Although the bicycle is provided with a pedal that is a driving means, it may be a moving means that is provided with a prime mover and receives the power of the prime mover to rotate the wheels to travel.

In (a) of FIG. 1-1, rolling rotation is made by contacting a road surface (including a track, a road, etc.) (slightly rotating in either direction at least in the opposite of rotation). It is also possible to freely rotate the rear wheel 2 and the rear wheel 2 which is freely rotatable and is connected to a small-diameter sprocket g2 (rotary body) composed of a toothed drive means so as to be rotatable.

Then, the elastic member 40 made of a spring shown in FIG. 9B is allowed to rotate in the forward and reverse directions within the expansion and contraction range of the elastic member 40.
-2 is alternately stepped on by the force (power) of the foot of the person getting on the moving means to transmit the power and the pressing force, so that the first member 21, the pressing structure c1, the second member 22, and the ring-shaped member r, the sprocket g2, and the rear wheel 2 are transmitted in this order to rotate the rear wheel 2 so that the rear wheel 2 can be rotated to travel on a road surface. 2 shows a transportation means consisting of a fixed bicycle. or,
The rotating bodies 9-1 and 9-2 composed of the pedal are the first member 2
This is an example of a driving means which is configured to be able to rotate more than one rotation relative to one and which can be connected to an external driving means or power so as to be freely rotatable.

Next, the speed change structure and the pressurizing structure c1 shown in FIGS. 1A and 1B will be specifically described. A circular shaft e1 (engaging means) protruding at a position of a substantially parallel central axis 84 provided at a distance from the central axis 81 is relatively connected (fixed) to the first member 21. The member 22 has an arcuate slot f at a position spaced from the central axis 81.
1 (engaging means) is provided, the shaft e1 and the elongated hole f1 are relatively fitted to each other, and the guide and the guide rail are configured to be movable including the slide relatively.
The second member 22 is relatively rotatably (slightly forward / reverse rotatively movable) held (similar to a shaft support) relative to the rotary shaft 30 connected to the first member 21 about the central axis 81. Between the stoppers of m and n indicated by an arrow in the drawing, for example, 30 between m and n.
The first member 21 and the shaft e are
The second member 22 is attached to the first member so as to be slightly movable in forward and reverse directions.

Further, a driving member k1 (rotating body) having a circular hole w1 is provided, and the hole w1 and the shaft e1 are fitted to each other so that the driving member k1 is centered on the central shaft 84 as the first member 21.
And the second member 2
2 is provided with a circular hole w2 at a position of a central axis 85 that is substantially parallel to the central axis 81 and is spaced from the central axis 81.
The shaft e2 of the driving member k2 (rotating member) including two and the hole w2 are fitted together, and the driving member k2 is held so as to be rotatable forward and backward relative to the second member 22 about the central axis 85. Further, the elastic member 40 (first means) has a restoring force capable of elastically expanding and contracting by transmission of the pressing force and returning to a substantially original state by the repulsive force of the pressing force.
A coil-shaped spring made of and is fitted and mounted between the driving member k1 and the driving member k2, and the first member 21
And the second member 22 are rotationally transmitted to each other, and constitute a speed change structure of the present invention including a pressurizing structure c1 composed of the first means and the second means.

The first member 21, the second member 22 (sprocket g1) and the sprocket g2 are configured to be capable of rotating one or more revolutions each, and the rotational force in either the normal direction or the reverse direction is input from any of them. Even if the first member 21 and the second member 2
2 and the sprocket g2 show a structure in which they are connected so that rotation can be transmitted. Further, when the sprocket g1 is rotated once, the sprocket g2 constitutes three speed increasing mechanisms. This configuration can also be configured using a speed reduction mechanism. Further, the elastic member 40 may be attached so as to pressurize between the first member 21 and the second member 22 without providing the driving members k1 and k2.

Next, the functions of the speed change structure, the pressure structure c1 and the moving means will be described. In the first embodiment described above, a person who rides on the moving means rides on the rotating body 9-
1 and 9-2 are alternately stepped on by the force of the human foot and the first member 2
By rotating 1 in the direction of j1 in the figure, the second member 2
The traveling of the moving means can be started by rotating 2 to rotate the wheels, but the resistance of the moving means and the person and the road surface are also generated, and the rotation of the first member 21 is accompanied by a large rotation resistance. There is a thing. When the pressure structure c1 is not provided, the rotation resistance causes at least the rear wheel 2
, Sprocket g2, ring-shaped member r, and second member 22
As a matter of course, the relative pressing force is applied to the first member 21 without being relieved, and the transmitting portion between these driving means is also subjected to the burden of the pressing force and is damaged or the power by the foot is also applied. The pressure may be forced, which may cause a burden.

However, when the pressurizing structure c1 is provided, when the rear wheel 2 or the second member 22 is rotated and rotation resistance is involved, the rotating member 9- When the rotational pressure is transmitted to 1 and 9-2, the driving member k1 and the second member 22 provided on the first member 21 side are provided.
Elastic member 4 located between the drive members k2 provided on the side
Since the pressure can be applied in the direction of shrinking 0, the applied pressure can be elastically absorbed in the elastic member 40 in a stepless manner and temporarily stored.

In this case, even if the second member 22 and the rear wheel 2 are not rotated, the pressing force is transmitted in the rotating direction. Then, the rotational speeds of the second member 22, the rear wheel 2, and the front wheel 3 are gradually increased from the vicinity where the rotational resistance force of the second member 22 and the rear wheel 2 and the pressing force in the elastic member 40 are relatively balanced. While being rotated, it becomes possible to drive the moving means. Further, after the moving means starts traveling, the applied pressure that is absorbed and stored in the elastic member 40 becomes a repulsive force, and the elastic member 40, the driving member k1, and the driving member k are moved.
The second member 2 in the direction in which 2 is restored to the original state including the original position and shape (in the case of the illustrated spring structure, the extending direction).
2 and other driving means and the rear wheel 2 can be output as rotational power. Therefore, the relative repulsive force (pressurizing force) stored after absorbing the pressurizing force can be output, and efficiency can be obtained without waste.

Further, when the applied pressure is elastically absorbed, the rotational angular velocity of the second member 22 may be delayed with respect to the rotational angular velocity of the first member 21 to alleviate the load on the driving means and the foot. In addition, it is possible to prevent the drive means from being damaged or obstructed. On the contrary, when the absorbed and stored pressure is output, the rotational angular velocity of the second member 22 can be made faster than the rotational angular velocity of the first member 21.
Therefore, even when traveling on a rough road surface including up to the start of traveling or when traveling uphill, during turning or during transmission of rapid acceleration due to power, the rotational resistance from the wheels is relatively large. The pressure resistance structure c1 absorbs and relieves the transmission of these rotational resistances and abrupt speeds to some extent, and the gears are appropriately shifted while adapting to road surface conditions and rotational resistances. It can be output as power.
In addition, it is possible to efficiently transmit the rotation while traveling while smoothly outputting the pressing force that is absorbed and stored as the rotation resistance is loosened or released. In particular, a bicycle is effective in that these functions and effects are likely to be realized, and the burden of power generated by a person can be effectively alleviated.

The speed change structure and the pressurization structure c1 are
When absorbing the pressing force and outputting the pressing force, the central axis 8
4, the driving member k1 is slightly rotated, and the central shaft 85
The driving member k2 is slightly rotated about the
It causes an effect that reduces the resistance when expanding and contracting.
Further, in the elastic member 40, an imbalance in which the outer diameters of the springs have the same diameter so that a strong repulsive force is obtained steplessly from the both ends (symbols x and y in the figure) to the middle position z. Since it has a large diameter, the rotational speed of the second member 22, the driving means and the wheels, and the traveling speed of the moving means are transmitted to the first member 21 while enabling a small stepless speed change. The burden of rotation resistance in power can be further reduced steplessly.

FIGS. 1-2 are schematic views showing further features of the speed change structure and the pressurization structure c1 of the first embodiment.
Further, FIG. 1-2 is based on (b) of FIG. 1-1, and FIG. 1-2 (a) shows that the first member 21 and the second member 22 are connected to each other. It is a schematic diagram showing a state when a pressure is about to be applied, and FIG. 6B is a partially enlarged view of FIG. 4A.
It is a figure which shows the condition which is moved by changing the relative distance ratio between a fulcrum, a force point, and an action point, absorbing the pressing force between them.

In FIG. 3A, when the second member 22 has a rotation resistance and the second member 22 is stopped or fixed, the first member 21 is rotated in the direction of arrow j1 in the figure. When the pressing force is applied, the pressure is applied near the pressing position s1 between the outer wall surface of the circular shaft e1 provided in the first member 21 and the inner wall surface of the hole w1 provided in the driving member k1. Suppose that occurs. In addition, it is shown that the pressure is applied near the pressure position t1 between the outer wall surface of the circular shaft e2 of the driving member k2 and the inner wall surface of the hole w2 of the second member 22. In addition, the straight line u1 formed by the dotted line shown in the figure acts on the elastic member 40 in the direction connecting the central axes 84 and 85 and having a relative angle to the axial direction of the central axis 81 itself. Indicates that it shrinks in the direction of arrow j2. In addition, the force point to which the power consisting of the pressing force is input is the straight line u
Assuming that the pressurization position s1 on 1 is, the point of action is the straight line u1.
It can be assumed that the upper pressure position t1. Further, the fulcrum for the force point and the action point can be assumed to be the central axis 81.
The power point, the fulcrum, and the point of action can be set to various positions other than the above positions, but they are assumed to be the above positions for easy explanation and understanding, and based on this assumption, Further description will be made.

In FIG. 2B, when the second member 22 has a rotational resistance, the first member 21 is rotated (applied pressure force) in the direction of the arrow j1 to move the central shaft 84 (84- in the figure).
It shows a state in which 1) is moved to the position of 84-2 in the figure. By this movement, the pressing position s1 is moved to the vicinity of the pressing position s2 in the drawing, and the pressing position t1 is the pressing position t in the drawing.
It is shown that it will be moved to a position near 2. Further, the straight line u1 formed by the dotted line indicates that the pressing force acts in the direction connecting the pressure positions s1 and t1 before the movement, and the straight line u1 formed by the dotted line
2 is the center axis 84 (84-2 in the figure) after movement and the center axis 8
It is shown that the pressing force acts in the direction connecting 5 and the pressing positions s2 and t2 are located on the straight line u2.

Further, when the pressing position s1 is moved to the s2 position, the pressing position of the force point is slightly moved in the direction away from the central axis 81 and changed by increasing the distance between the force point and the fulcrum. By moving the pressurizing position t1 to the t2 position, the pressurizing position of the action point is largely moved in the direction approaching the central axis 81, and the distance between the action point and the fulcrum is decreased to be changed. It is shown that this movement changes the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the action point and the fulcrum. Further, it is shown that the second means of the pressurizing structure is provided. Therefore, the elastic member 40
When the pressing force is absorbed by the (first means of the pressurizing structure), the ratio of the distance between the force point and the fulcrum and the distance between the action point and the fulcrum can be changed steplessly, and the elastic member can be further changed by this change. It is possible to gradually expand and contract 40 without steps and at a non-constant speed, and to stop or transmit smoothly receiving a pressing force or a repulsive force. Further, even when the absorbed pressing force is output, the rotational angular velocity of the second member 22 relative to the rotational angular velocity of the first member 21 can be steplessly changed.

In the speed change structure and the pressurizing structure c1 shown in FIGS. 1-1 and 1-2, the distance between the central shaft 84 and the central shaft 81 and the central shaft 81 are within the scope of the gist of the present invention. On the other hand, the distance between the central axes 85 may be the same or different. Further, the diameters of the holes w1 and w2 may be the same or different. Further, the first member 21 and the second member 22 may be relatively provided with a plurality of pressurizing structures composed of the first means and the second means.

FIG. 2 is a schematic view showing a second embodiment and features of the speed change structure of the present invention including a plurality of pressurizing structures. The figure (a) is a front view, the figure (b) is a sectional view of a right side surface, and the figure (c) is a fulcrum and a force point when the pressurizing force is absorbed between the first member 21 and the second member 22. FIG. 5 is a diagram showing a change in a point of action and an enlarged view showing a part of the front view.

In the speed change structure shown in FIG. 2, the first member 21 and the second member 22 are relatively rotatably supported about the central shaft 81, and the second member 22 is composed of gears.
The member 21 is provided with a plurality of substantially quadrangular elongated holes f1 so as to surround the center axis 81 at a position where a distance is provided with respect to the center axis 81, and the second member 22 is also provided at a position where a distance is provided with respect to the center axis 81. A plurality of substantially quadrangular elongated holes f2 surrounding the central axis 81, and a plurality of rubbers made of elastic members 41 (first means) that are elastically expandable and contractible and can restore the shape. The elastic members 41 are fitted in both the long holes of the hole f2, and the stoppers of m and n shown in the drawing, which are both ends of the elastic member 41, are configured by a right-down inclined surface, and the elastic member 41 resembles a rhombus. The speed change structure is provided with the pressurizing structure c2 configured as described above. The first member 21 and the second member 22 are each 1
The first member 21 and the second member 22 are configured so that they can rotate more than the rotation, and the first member 21 and the second member 22 are rotatably connected to each other regardless of which of the forward and backward rotational forces is input.

Next, the features of the speed change structure and the pressurizing structure c2 will be described. For example, the arrow j
When the second member 22 is rotated in one direction and a rotational resistance is given to the second member 22, the elastic members 41 fitted in the elongated holes f1 and f2 absorb the pressing force while receiving the power transmission, and the arrow j2 direction. It will shrink relative to. Further, when the transmission of power is released, the elastic member 41 expands in the direction in which it is restored to the original state by the repulsive force, and the repulsive force becomes the rotational force and becomes the first member 21.
Therefore, at least one of the second members 22 is rotated.

Further, as shown in FIG. 3A, the first member 2
1 is about to start rotating in the direction of the arrow j1 by the input power, the inner wall surface of the slot f1 of the first member 21 and the elastic member 4
The pressure is particularly large at the pressure position s1 at one end of No. 1 and at the pressure position t1 at the inner wall surface of the slot f2 of the second member 22 and the other end of the elastic member 41. In the figure, the distance between the central axis 81 (fulcrum) and the pressing position t1 (point of action) is shorter than the distance between the central axis 81 (fulcrum) and the pressing position s1 (force point).

FIG. 6C shows the case where the first member 21 is further rotated in the direction of arrow j1 (or the direction opposite to the arrow j1) from the state of FIG. 6 shows a state in which the shape is changed while shrinking in the direction of j2 in the figure to absorb the applied pressure. The pressure at the pressure position s1 and the pressure position t1 which is the contact portion between the inner wall surface of the elongated hole f2 and the elastic member 41 is further increased,
Further, it is shown that the elastic member 41 is elastically changed in shape to relatively move the pressurizing position in the pressurizing positions s2 and t2, thereby increasing the pressurizing area as a whole. It is shown that when further pressing force is applied, the pressing position is further moved to the pressing positions s3 and t3 and the pressing area is increased.

In the same figure (c), the central axis 81 (fulcrum)
And the center axis 81 with respect to the distance between the pressurizing position s2 (power point)
It shows a state where the distance between the (fulcrum) and the pressurization position t2 (action point) is equal, and the central axis 81 (fulcrum) and the pressurization position s3.
It is shown that the distance between the central axis 81 (fulcrum) and the pressing position t3 (point of action) is increased with respect to the distance between (power points). Therefore, the force point is moved toward the central axis 81, the point of action is moved away from the central axis 81, and the pressing position s
It becomes possible to change the ratio of the relative distance between the relative force point and the fulcrum, the relative action point and the fulcrum, while expanding from the position 1 to s3 and the position from the pressurization position t1 to t3. The second means of the pressure structure is realized.

The functions of the speed change structure and the pressurization structure c2 exhibit substantially the same effect as that of the first embodiment shown in FIGS. 1-1 and 1-2, which can absorb the pressing force and obtain the repulsive force. In addition, since the elastic member 41 has a partially inclined surface and the pressing position is changed, even if the elastic member 41 has a large repulsive force, the pressing force can be absorbed steplessly. However, the ratio of the relative distance between the force point, the fulcrum, and the action point is changed steplessly to further change the absorption of the pressing force and the repulsive force steplessly, and the relative rotational angular velocity between the first member 21 and the second member 22 is changed. It is the same in that it can be changed smoothly.

Further, the elastic member 41 accommodated in the elongated holes f1 and f2 may have a shape other than that shown in the drawing, or may have the same outer shape as the elongated holes f1 and f2, but the distance between the force point and the fulcrum in the internal configuration. Alternatively, the ratio of the distance between the fulcrum and the action point can be changed. For example, the elastic member 41
Another elastic member such as a sponge, which is weaker than the repulsive force of the elastic member 41, is inserted in the gap between the slot and the slot (f1 and f2).
1 and f2 may be provided to fill the gap, and by this, the ratio of the relative distances between the force point, the fulcrum, and the portion to be the action point can be changed in substantially the same manner.

FIG. 3 is a schematic view showing a third embodiment of the speed change structure of the present invention including a plurality of pressurization structures and its features. The figure (a) is a front view, the figure (b) is sectional drawing of a right side, and the figure (c-1) and the figure (c-2) are the 1st member 2.
It is a figure showing a situation where a fulcrum, a power point, and an action point are moved from the time of starting to absorb the pressing force between 1 and the 2nd member 22, and the front view (a) is partially omitted. It is a figure.

The speed change structure shown in FIG. 3 is a structure in which the first member 21 and the second member 22 are relatively rotatably supported about the central shaft 81. Central axis 8
The circular shape is provided at the respective positions of the rotary shaft 30 having a circular hole w1 near 1 and the central axes 82, 83, 84 and 85 which are provided at the same distance with respect to the central axis 81 and are substantially parallel to the central axis 81. A plurality of elastic members 42 (the first and second elastic members 42 having the circular outer shape) are provided with shafts e3 having outer wall surfaces at respective positions, and further have circular holes w4 so as to be expandable and contractible and to be able to restore the original shape. 1 means) is fitted to each of the plurality of shafts e3, and the plurality of elastic members 42 are rotatable about the central shafts 82, 83, 84 and 85 with respect to the shaft e3 (connected and fixed to the shaft e3). It may be done). Further, the elastic member 42, the shaft e3, the central shafts 82, 83, 84 and 85 are positioned so as to surround the central shaft 81. In addition, the second member 22 is connected to the gear and the rotary shaft 30 connected to the first member 21.
A circular hole w2 that is fitted with the circular hole w2 and a plurality of circular holes w3 that are provided at different positions with respect to the central axis 81 are provided at different positions. Then, the rotary shaft 30 of the first member 21 and the hole w2 of the second member 22 are fitted to each other, the elastic member 42 is further inserted into the hole w3, and a part of the outer peripheral surface of the elastic member 42 is provided on the inner wall surface of the hole w3. The speed change structure is provided with a pressurizing structure c3 in which the first member 21 and the second member 22 are arranged to be pressure-connected and relatively rotatable with respect to the central axis 81.

In the figure, in order to facilitate understanding, a circular hole w with respect to the diameter of the circular elastic member 42 is formed.
3 and the center of the circle of the circular hole w3 and the center axis of each elastic member 42 (center axes 82, 83, 84,
There is a slight distance between 85). It is possible to configure them so that they are on the same center, but it is desirable to construct them within the scope of the gist of the present invention. In addition, the first member 21 and the second
The member 22 is configured to be capable of rotating one or more revolutions each, and the first member 21 and the second member 22 are connected so that rotation can be transmitted regardless of which rotational force in the forward direction or the reverse direction is input. It is made to be a structure.

Next, the features of the speed change structure and the pressurization structure c3 will be described with reference to FIGS. 3 (c-1) and 3 (c-2). For example, when the first member 21 is rotated in the direction of the arrow j1 by the input power and the second member 22 is given a rotation resistance to be stopped or fixed, the elastic member 42 located in the hole w3 is rotated by the power of the rotation. The pressure force is absorbed while being transmitted, and it is expanded and contracted in the relative direction indicated by the arrow j2 in FIG.
Further, if the transmission of power or the rotation resistance is canceled, the elastic member 42
Is expanded and contracted in the direction in which it is restored to the original state by the repulsive force, and the repulsive force becomes the rotational force, and at least one of the first member 21 and the second member 22 is rotated and restored to the original state. become.

Further, the first member 21 is driven by an input power to generate an arrow j1.
When it is about to start rotating in the direction, as shown in FIG. (C-1), the power is applied to the contact portion between the shaft e3 of the first member 21 and the inner wall surface of the hole w4 and the pressure position s1 in the drawing. It can be assumed that the central axis 81 serves as a fulcrum, the contact point between the outer wall surface of the elastic member 42 and the inner wall surface of the hole w3, and the vicinity of the pressing position t1 in the figure is the point of action. it can.
In this state, when the first member 21 is about to start rotating slightly in the direction of the arrow j1, in the initial stage, the pressing positions s1 and t1
Although the pressing force and resistance are hardly transmitted to the elastic member 42, the pressing force and resistance between the first member 21, the elastic member 42, and the second member 22 increase steplessly as the rotation angle increases. become. Further, the absorption of the pressing force in the elastic member 42 is carried out very smoothly and steplessly, and the repulsive force is also increased very gently and steplessly.

Further, as shown in FIG. 2 (c-2), when the second member 22 has a rotation resistance, the first member 21 is further rotated in the direction of arrow j1 (which may be the opposite direction of arrow j1). Then, the elastic member 42 expands and contracts to change its shape.
The pressing position t1 (position of the point of action) indicated by -1) is moved in the directions of pressing positions t2 and t3 to increase the pressing area of the elastic member 42, and the pressing position t2 is slightly different. It is shown that the central axis 81 is approached and the pressurization position t3 is significantly approached to the central axis 81. For example, pressure positions t2 and t3
Fig. (C-2) with respect to Fig. (C-1) at least at an intermediate action point (the most concentrated position of the applied pressure vector) as an average action point. It means that the action point of () is close to the central axis 81. Therefore, it is possible to absorb the pressing force very smoothly while changing the ratio of the distance between the force point and the fulcrum and the distance between the action point and the fulcrum. It also shows that the second means of the pressure structure is provided. Further, by releasing the transmission and absorption of the pressing force, the first member 21, the second member 22 and the elastic member 42 can be restored to their original shapes, positions and states.

As described above, the speed change structure and the pressurizing structure c3 shown in the third embodiment are substantially the same as the speed change structures shown in the first and second embodiments. By absorbing the force, the portions that can be the force point, the fulcrum, and the action point are relatively moved, and the absorption of the pressing force and the repulsive force are further changed steplessly, and the It is possible to change the rotational angular velocity of the two members 22 by further delaying it infinitely.

FIG. 4 is a schematic diagram showing the features and features of a speed change structure and a pressurizing structure according to a fourth embodiment of the present invention. The figure (a) is a front view, the figure (b) is sectional drawing of a right side, and the figure (c-1) and (c-2) absorb the pressurization force between a 1st member and a 2nd member. It is a figure showing the situation where a fulcrum, a power point, and a point of action when it absorbs from the time of beginning to be moved, and Drawing (c-2) is an enlarged view which abbreviate | omitted a part of said front view (a).

The speed change structure shown in the figure includes a second member 22,
The first member 21 has a structure capable of being rotatably supported relative to the central axis 81 relative to each other, and is configured to be rotatable for one rotation or more. Whichever the rotational force is input from the first member 21 and the second member 2
2 is a structure that can be connected so that rotation can be transmitted.

The structure of the first member 21 shown in FIGS. 9A and 9B is a curved surface (a shape other than a circular shape may be used, which is composed of outer wall surfaces having substantially the same radius with the central axis 81 as the center, and is constituted by a gear. The hole w7 is formed in the direction of the central axis 81.
And the hole w6 are relatively provided in a cylindrical shape, and are formed by an arcuate relative wedge surface having a radius smaller than the radius of the hole w7 (a relative inclined surface other than the arcuate shape may be used). The hole w5 is provided with a plurality of groove-shaped curved surfaces q9 which engraves the inner wall surface of the hole w7, and further has an outer wall surface formed into a cylindrical shape (may be a shape other than a cylindrical shape) including a circular curved surface q4. The third member 23 is arranged in the plurality of holes w5 one by one (a plurality may be provided), and the third member 23 is provided in the first member 21 so as not to fall off from the hole w5 (first
It may be fixed, rotatable or movable with respect to the member 21), and is movable within the holding means v by being partially surrounded by the surface in the arrow j1 direction and the surface in the opposite direction j3 direction in the holding means v. (It may be rotated or swung freely). Further, elasticity provided in the first member 21 and the holding means v so as to bring the third member 23, which is rotatably held around a position away from the central shaft 81, toward the central shaft 81 side. The pressure is applied by the member 43.

Further, the third member 23 is approached to the central shaft 81 in a rotation direction of the first member 21 (a direction other than the rotation direction) which is different from the forward and reverse directions and the rotation direction. It is held so as to be slightly movable and pressurizable in the forward and reverse directions, that is, the direction away from and the direction away from it. Further, the plurality of holes w5 and the third member 23 are configured to surround the central axis 81, but the holes w5 are located at a position close to the central axis 81.
6 is configured. The radius of the outer circumference of the third member 23 is smaller than the radius of the hole w5. The configuration of FIGS. (C-1) and (c-2) corresponds to the first member 21.
Into the hole w6 of the second member 22, the second member 22 configured by including the curved surface q2 having the circular outer wall surface having the substantially same radius with the central axis 81 as the center is inserted, and the outer wall surface of the second member 22 is inserted. While being surrounded, the curved surface q2 of the second member 22 and the third member 2
3 is a diagram showing a state in which the curved surfaces q4 of the outer wall surface of No. 3 and the curved surface q9 of the first member 21 and the curved surface q4 of the outer wall surface of the third member 23 are in contact with each other. This is the purpose of configuring the gear shift structure.

Next, the features of the speed change structure and the pressurization structure c4 will be described with reference to (c-1) and (c-2) of FIG. For example, when the first member 21 is rotated in the direction of the arrow j1 by the input power and the second member 22 is stopped or fixed by giving the rotation resistance, the third member 23 located in the hole w5 is w
While receiving the transmission of the pressing force from the curved surface q9 in 5 and absorbing the pressing force by the elastic member 43, the elastic member 43 slightly rolls or moves in the direction of the arrow j4 with respect to the curved surface q2 of the second member 22, It is sandwiched between the curved surface q9 of 21 and the curved surface q2 of the second member 22, and pressure is applied while being stuck. If the rotational resistance of the second member 22 is small with respect to this pressing force, the second member 22 will rotate in the direction of arrow j1.

On the contrary, when the second member 22 is rotated in the direction of the arrow j1 by the input power, and the first member 21 is stopped or fixed by giving the rotation resistance, the curved surface q2 of the second member 22. Presses the curved surface q4 of the third member 23,
Presses the elastic member 43 and presses the curved surface q9 in the hole w5 of the first member 21 while absorbing the pressing force by the elastic member 43, and the third member 23 of the second member 22 and the curved surface q2 of the first member 21. If the rotation resistance of the first member 21 is small, the first member 21 has a small rotation resistance because the first member 21 has a small rotation resistance while rolling or rotating slightly with respect to the curved surface q9 in the hole w5.
The member 21 is rotated in the direction of arrow j1.

In this state, as shown in FIG. 2 (c-2), the elastic member 43 is relatively compressed and contracts due to the expansion and contraction force. Further, if the transmission of the rotational power or the rotational resistance is released, the elastic member 43 becomes elastic. The member 43 expands in the direction in which it is restored to the original state by the repulsive force, and the repulsive force becomes the rotational force, and at least one of the first member 21 and the second member 22 is rotated and restored to the original state. It will be a matter. In addition, the first member 21 is driven by the input power to generate an arrow j.
When trying to start rotating in one direction, see Figure (c-1).
As shown in, the curved surface q9 in the hole w5 of the first member 21
The vicinity of the pressurizing position s1 in the drawing, which is the contact portion of the member 23 with the curved surface q4, is the first force point for transmitting power, and the central axis 8
1 serves as a fulcrum, and the curved surface q4 of the third member 23 and the second member 2
The contact point between the second curved surface q2 and the vicinity of the pressurizing position t1 in the figure can be the point of action.

In this state, the pressing positions s1 and t1 are initially set when the first member 21 is about to start slightly rotating in the direction of arrow j1 (or the direction opposite to the direction of arrow j1).
Although the pressing force and the resistance are hardly transmitted to the third member 23, the pressurization position s1 is changed to the pressurization position s as the rotational resistance of the second member 22 is increased to increase the rotation angle of the first member 21.
2, the pressurization position t1 is moved to the pressurization position t2, and the force point approaches the central axis 81. Further, the absorption of the pressing force in the elastic member 43 is carried out very smoothly and steplessly, and the repulsive force is also increased very gently and steplessly.

Further, substantially the same effect can be obtained by rotating the second member 22 in the direction opposite to the j1 direction. Further, when the second member 22 is rotated in the j1 direction or the j3 direction, the pressing position s1. Is a point of action, and the pressurizing positions t1 and t2 are points of force. Further, the pressing direction between the first member 21 and the second member 22 is
It is possible to freely transmit and receive (may be locked) the pressing force in a direction that does not face the central axis 81 and in a direction of the rotation direction j1 or j3 or a direction connecting the force point and the action point. .

As described above, also in the speed change structure and the pressurizing structure c4 shown in the fourth embodiment, the first or second or third structure is used.
The effect similar to that shown in the embodiment can be obtained, and in particular, since the elastic member 43 absorbs the pressing force, the force point, the fulcrum, and the portion that can be the action point are further moved while absorbing the pressing force. And further changing the repulsive force steplessly, further retarding the rotational angular velocity of the second member 22 (first member 21) or changing the rotational angular velocity of the second member 22 (first member 21) with respect to the rotational angular velocity of the first member 21 (second member 22). Is possible.

Further, in FIG. 4, the third member 23 is constituted so as to be rotatable forward and backward about a central axis substantially parallel to the central axis 81. Alternatively, it may be configured so as to be freely rotatable in the forward and reverse directions about the inclined central axis. Further, although the second member 22 is formed in a cylindrical shape,
The outer peripheral curved surface having various circular shapes including a cylindrical shape, a cylindrical shape, a conical shape, and the like can be provided and configured. Also, hole w6
Even on the inner surface of the outer peripheral surface of the third member 23
Although the surface is parallel to the center axis 81, it may be a surface which is not parallel to the central axis 81 and is inclined in a relatively straight line or curved line.

Particularly, in the speed change structure and the pressure structure c4 of FIG. 4, the speed change structure and the pressure structure of the present invention can be realized only by inserting the second member 22 into the hole w6 of the first member 21. Be efficient. Further, by making the outer periphery of the first member 21 circular and the end portion thereof an arcuate inclined surface q10 and the end portion of the third member 23 also an arcuate inclined surface similar to the inclined surface q10, This is more convenient because it is possible to smoothly press-fit or insert a member having a relative arc including a cylindrical shape or a cylindrical shape to fasten it. Therefore,
It is also possible to utilize the structure of the first member 21 to form a pressurizing structure including a single driving means and fastening means.

The above is a description of a simple embodiment of the speed change structure of the present invention including the first means and the second means of the pressurizing structure and the features thereof. As the function described in the above embodiment, even if the first member 21 is pressed in any of the forward and reverse rotational directions about the central axis 81, the second member 22 is continuously pressed while the pressing force is absorbed by the pressing structure. While being able to receive the pressing force transmitted from the first member 21 while being accompanied by the repulsive force of the absorbed pressing force, the second member 21 can be rotated about the central axis 81 in either forward or reverse rotation directions. The first member 21 has a function of receiving the pressing force transmitted from the second member 22 and being able to rotate even if it is pressurized to. Further, when receiving the pressing force, the relative rotation angular velocity between the first member 21 and the second member 22 can be changed steplessly by the first means and the second means which are composed of a pressurizing structure. It is a thing.

In the embodiment described below, the structure and function of the above embodiment are latent (internal or equipped),
Further, the transmission structure and the pressurization structure of the present invention have latent (internal or equipped) elements capable of exhibiting a plurality of special functions.

The basic structure A in which the elements capable of exhibiting the plurality of special functions are hidden is the above-mentioned pressurizing structure capable of receiving the pressurizing force of rotation and elastically absorbing the pressurizing force. A flexible elastic member 43 composed of a first means that freely and repulsively absorbs the applied pressure, and an action point and a fulcrum between the action point and the fulcrum that are transmitted with respect to the distance between the force point and the fulcrum that transmit the pressure force. A relative wedge surface composed of the second means capable of changing the distance ratio, and at least two members rotatably supported (meaning similar to holding) relatively rotatable about the central axis 81. And a third member that is movably held (similar to shaft support) in at least one of the two members at any position away from the central axis 81, including rotation, slide, and swing. The member and the two members centering on the central axis 81 To rotatably less or relatively four induced to stop or fixing eye and a member is held comprising also, the four members first member respectively 2
1 and the second member 22, the third member 23 and the fourth member 24,
At least one of the first member 21, the second member 22, the third member 23, and the fourth member 24 is provided with the pressing structure, and the first member 21, the second member 22, and the third member 23 are provided. And the fourth
The pressing force of the rotation is absorbed and received by at least one of the members 24 by the pressurizing structure, and the relative rotational angular velocity can be continuously changed with the repulsive force of the absorbed pressing force. It is configured.

Further, in the basic structure A in which the elements capable of exhibiting the plurality of special functions are hidden, at least the following five functions and configurations can be established.

The first function is ... the first member 21, the second member 22, and the fourth member 24 about the central axis 81, which is the same central axis, as the pivotal support means 90 (a relatively fixed member or a rotary member). May be rotatably supported relative to each other), and further relative to at least one of the first member 21 and the second member 22 at a position spaced from the central axis 81. Provided with a third member 23 that is movably held
Rotational transmission between the first member 21 and the second member 22 is transmitted to the first member 2
The first and second members 22, the third member 23, the wedge surface relative to the third member 23 and the elastic member 43 are configured to transmit and receive the pressing force of rotation, and the pressing force from the third member 23 is transmitted to the fourth member. The member 24 is configured to be able to transmit and receive the pressing force of rotation, and the third member 23 is configured to be unable to receive the transmission of the pressing force from the transmission of the pressing force from the fourth member 24. In this case, the pressing force transmitted from the first member 21 is applied to the third member 23 regardless of whether the first member 21 is pressed in one of the forward and reverse directions about the central axis 81 and rotated once. The pressure force is absorbed steplessly by the first means and the second means of the structure, and the second member 22 receives the pressure force transmitted from the first member 21, and the forward and reverse directions are accompanied by the repulsive force of the absorbed pressure force. Approximately one rotation in either direction (approximately once And it is exactly under the influence of pressure the structure having a function that is 1 is slightly greater than the range slightly or 1 rotates less than the rotation.).

In this case, when the fourth member 24 has a rotation resistance, the fourth member 24 is stopped while the second member 22 is rotated by the transmission of the rotational pressure from the first member 21. The function that can do is also possible. Further, even if the second member 22 is pressed in one of the forward and reverse directions about the central axis 81 and rotated once, the pressing force transmitted from the second member 22 is the same as that of the third member 23 and the pressing structure. The first member and the fourth member 24 absorb the pressure force steplessly by the first and second members.
Has a function of receiving the pressing force transmitted from the second member 22 and being rotated by one revolution in either the forward or reverse direction with the repulsive force of the absorbed pressing force.

Further, when the rotation resistance means capable of generating rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, the central shaft 8
Even if the fourth member 24 is pressed in one of the forward and reverse rotation directions about 1 and rotated once, the pressing force transmitted from the fourth member 24 is applied to the first member 21 and the second member 22. It is possible to rotate the fourth member 24 approximately one direction in either forward or reverse directions without being received by the first means and the second means of the structure.

By applying the first function by realizing the first configuration and the first function, the following second, third and
Elements capable of showing the fourth and fifth functions are hidden in the basic structure A.

As the second function, the first member 21 is fixed to the shaft support means 90 and the second function is performed based on the first structure.
In the case of the configuration, even if the pressing force of one rotation is transmitted to the second member 22 in either the forward or reverse rotation direction, the pressing force is absorbed steplessly by the first means and the second means of the pressing structure. The first member 21, the third member 23, the fourth member 24, and the shaft support means 90 receive the pressing force transmitted from the second member 22 and rotate the second member 22 with the repulsive force of the absorbed pressing force. Against the rotation of the second member 22 or with the repulsive force of the absorbed pressing force, the first member 21, the third member 23, the fourth member 24, and the shaft support means 90 It makes about one full rotation about the central axis 81.

As a third function, the second member 22 is fixed to the shaft support means 90 while being based on the above-mentioned first structure, and the third function is achieved.
In the case of the configuration, even if the pressing force of one rotation is transmitted to the first member 21 in either the forward or reverse rotation direction, the pressing force is absorbed steplessly by the first means and the second means of the pressing structure. At least, the second member 22 and the shaft support means 90 receive the pressing force transmitted from the first member 21 and give a large resistance to the rotation of the first member 21 with the repulsive force of the absorbed pressing force. The first member 21 is prevented from rotating, or the second member 22 and the shaft supporting means 90 are rotated about the central axis 81 at least about one rotation while accompanied by the repulsive force of the absorbed pressure.

The fourth function is ... In the case of the fourth structure in which a slight rotational resistance is provided between the first member 21 and the shaft support means 90 while being based on the first structure, the second member is used. Even if 22 is pressed in the positive direction and rotated once, the pressing force is absorbed steplessly by the third member 23 and the first and second means of the pressing structure, so that at least the first member 21 and the fourth member. A24 receives the pressing force and is rotated about one revolution in the forward direction with the repulsive force of the absorbed pressing force. Further, it is possible to continue the rotation of the fourth member 24 even if the rotation of the second member 22 is stopped while the fourth member 24 is being rotated in the positive direction. Further, it has a function of preventing the first member 21 and the second member 22 from rotating even if the fourth member 24 is rotated in the forward direction.

The fifth function is to apply a rotation resistance between the fourth member 24 and the shaft supporting means 90 while fixing or stopping the fourth member 24 and the shaft supporting means 90 based on the first structure. In the case of the fifth configuration described above, if the first member 21 is pressed in the positive direction and rotated once, the third member 23 and the first member of the pressing structure are pressed.
The second member 22 absorbs the pressure force infinitely by the means and the second means, receives the pressure force transmitted from the first member 21, and has a repulsive force of the absorbed pressure force. Is rotated. However, when the second member 22 is pressed in the direction for rotating the first member 21 once in the forward direction or the reverse direction when the rotational force is not transmitted to the first member 21, the second member 22
The pressing force transmitted from the fourth member 24 and the third member 23 is
The first member and the second member of the pressurizing structure absorb the pressure force steplessly, and the first member 21, the third member 23, and the fourth member 24 are accompanied by the repulsive force of the absorbed pressure force.
It is received by the shaft support means 90, and a large resistance is given to the rotation of the second member 22 while being accompanied by the repulsive force of the absorbed pressing force, so that the rotation of the second member 22 is blocked or absorbed. The first member 21, the fourth member 24, and the shaft supporting means 90 have a function of being rotated about the central axis 81 about one rotation in the positive direction while being accompanied by the repulsive force of the pressing force.

Other functions are as follows: By understanding and utilizing the configurations and functions described in 1 to 5 above, a plurality of further configurations and functions are inherent, and it is also possible to utilize the further configurations and functions. is there.

The shifting structure and the pressing structure c5 shown in FIG.
Is a structure in which the second member 22 and the first member 21 can be rotatably supported about a central axis 81, each of which is configured to be rotatable for one rotation or more. No matter which rotational force in the opposite direction is input from which one, the first member 21
The second member 22 and the second member 22 have a structure capable of being connected so that rotation can be transmitted.

First, a description will be given based on the first function and the first configuration. The first member 21 has the configuration shown in FIGS.
And the second member 22 is a schematic view showing that the second member 22 is rotatably supported relative to the shaft supporting means 90 about the central shaft 81. Further, the second member 22 is formed of a curved surface q2 (having a shape other than a circular shape, or may be formed of a gear) having outer wall surfaces having substantially the same radius around the center axis 81, and the direction of the center axis 81. Has a substantially cylindrical shape or a tubular shape in which a hole w7 and a hole w6 are relatively provided, and an arc shape having a radius smaller than the radius of the hole w7 (a relative inclined surface other than the arc shape may be used). The plurality of holes w5 are formed by a curved surface q9 which is a groove-shaped and inclined relative wedge surface that engraves the inner wall surface of the hole w7. In addition, in the hole w5, the curved surface q9 can be freely rotated and reciprocally moved.
A plurality of third members 23 that can be pressed relative to
It is attached so as to surround. Also, the third member 2
Reference numeral 3 denotes a curved surface q4 which is formed in a cylindrical shape and is composed of its outer wall surface.
Is connectable to the curved surface q9 of the second member 22 in a freely pressurizable manner. Further, the first member 21 movably holds the third member 23 including rotation and forward / reverse motion of the plurality of third members 23 at a position spaced apart from the central axis 81, and the rotation j1. The elastic member 43 is provided on the surface in the direction j3 and the surface in the direction j3 to press the third member 23 in the direction of the central axis 81. Next, the configurations shown in (c-1) and (c-2) of FIG.
A curved surface q composed of circular outer wall surfaces with a radius of approximately 1
3 and the curved surface q3 of the fourth member 24 and the first member 21.
A plurality of third members 23 that are movably held by the third member 23 and are arranged so as to surround the central shaft 81, are pressurizedly connected to the surfaces of the curved surfaces q4 of the third member 23 that are close to the central shaft 81.
The member 24 is rotatably supported relative to the shaft support means 90, the first member 21, and the first member 23 about the central shaft 81, thereby establishing the first configuration.

In the figures (c-1) and (c-2), the fulcrum is the central axis 81, and the pressure position to be the force point or the action point is s.
It is also assumed to be indicated by the symbol t. The figure (c-2) is
It shows a state in which the first member 21 is pressed (rotational power is input) in the rotation direction j1 from the state of FIG.
When the second member 22 and the fourth member 24 have a rotation resistance,
When the first member 21 is pressed in the j1 direction, the elastic member 43 presses the third member 23 in the j1 direction, and the third member 23 presses the curved surface q9 and the second member 22 in the j1 direction to rotate them. . Further, the pressing force of the rotation of the first member 21 is
If it is not transmitted to the fourth member 24, the third member 23 rolls or rotates or slides in the rotation direction J4 with respect to the curved surface q3 of the fourth member 24, so that the fourth member 24 can be kept in a non-rotated state. Also, due to this pressurization, the elastic member 43 and the third
The pressing position s1 with the member 23 becomes the force point, and the third member 23
The pressing position t1 between the curved surface q9 and the curved surface q9 (relative wedge surface) becomes the point of action and the pressing position t in the direction of approaching the central axis 81.
While being moved to 2, the pressing force transmitted from the first member 21 is absorbed by the expansion and contraction of the elastic member 43, and the third member 23, the curved surface q9, and the second member 22 relatively receive the first pressure.
The rotational angular velocity of the second member 22 can be delayed with respect to the rotational velocity of the member 21, and the repulsive force of the elastic member 43 after the rotational angular velocity of the first member 21 and the second member 22 become the same velocity. And the third member 23 and the curved surface q9
It is also possible to make the rotational angular velocity of the second member 22 faster than the member 21.

Next, when the first member 21 is pressed in the j3 direction, the elastic member 43 presses the third member 23 in the j3 direction,
The third member 23 can press and rotate the curved surface q9 and the second member 22 in the j3 direction. If the pressing force of the rotation of the first member 21 is not transmitted to the fourth member 24, the third member 23 rolls or rotates or slides on the curved surface q3 of the fourth member 24, so that the fourth member 24 is not rotated. You can keep the condition. Also, due to this pressurization, the elastic member 43 and the third member 2
The pressing position s2 with respect to 3 becomes the force point, and the pressing position t1 between the third member 23 and the curved surface q9 becomes the acting point and is moved to the pressing position t3 in the direction approaching the central axis 81, The pressing force transmitted from the member 21 can be absorbed by the elastic member 43, and the rotational angular velocity of the second member 22 can be delayed with respect to the rotational speed of the first member 21 while the curved surface q9 and the second member 22 are relatively received. After the rotational angular velocities of the first member 21 and the second member 22 become the same, the repulsive force of the elastic member 43 and the curved surface q9 make the rotational angular velocity of the second member 22 faster than the first member 21. Will also be free.

Next, when the second member 22 is pressed in the direction of rotation j1, the curved surface q9 presses the third member 23, and the third member 23 is pressed.
The member 23 is sandwiched between the curved surface q9 and the curved surface q3 of the fourth member 24 while approaching in the direction of the central axis 81 along the curved surface q9, and the elastic member 43, the first member 21, and the fourth member 21
The member 24 is pressurized and the first member 21 and the fourth member 24 are
It is possible to rotate in the j1 direction while receiving the pressing force transmitted from the member 22. Further, due to this pressurization, the elastic member 43 expands and contracts while absorbing the pressurizing force, and the pressurization position t1 between the curved surface q9 and the third member 23 moves to the pressurization position t3 in the direction approaching the central axis 81 as a force point. While the pressing position s1 between the third member 23 and the elastic member 43 serves as an action point, the pressing force transmitted from the second member 22 is applied to the curved surface q9, the elastic member 43, the first member 21, and the fourth member 24. It is possible to delay the rotational angular velocities of the first member 21 and the fourth member 24 with respect to the rotational velocity of the second member 22 while receiving the first member 21, the second member 22, and the fourth member 24.
After the rotational angular velocities of the second member 2 become the same, the repulsive force of the elastic member 43, the curved surface q9, and the third member 23 cause the second member 2 to rotate.
It is also possible to increase the rotational angular velocities of the first member 21 and the fourth member 24 faster than 2.

Next, when the second member 22 is pressed in the direction of rotation j3, the curved surface q9 presses the third member 23, and the third member 23 is pressed.
The member 23 is sandwiched between the curved surface q9 and the curved surface q3 of the fourth member 24 while approaching in the direction of the central axis 81 along the curved surface q9, and the elastic member 43, the first member 21, and the fourth member 21
The member 24 is pressurized and the first member 21 and the fourth member 24 are j3
It can be rotated in any direction. Also, due to this pressurization
The elastic member 43 expands and contracts while absorbing the applied pressure, and the curved surface q
The pressing position t1 between the third member 23 and the elastic member 43 becomes the point of action while the pressing position t1 between the third member 23 and the elastic member 43 is moved to the pressing position t2 in the direction approaching the central axis 81. The pressing force transmitted from the second member 22 to the curved surface q9.
The elastic member 43, the first member 21, and the fourth member 24 receive the first member 21 against the rotational speed of the second member 22 while receiving the same.
And the rotational angular velocity of the fourth member 24 can be delayed, and after the rotational angular velocity of the first member 21, the second member 22, and the fourth member 24 become the same velocity, the repulsive force of the elastic member 43 and the curved surface. It is also possible to make the rotational angular velocities of the first member 21 and the fourth member 24 faster than the second member 22 by q9 and the third member 23.

Next, when the fourth member 24 is rotated in the forward and reverse directions of the rotation directions j1 and j3 while the first member 21 and the second member 22 are stopped or the rotation resistance is given, the third member is rotated. Two
3, the elastic member 43, the curved surface q9, the first member 21, the second member 22, and the shaft supporting means 90, if the pressing force of the rotation of the fourth member 24 cannot be received, only the fourth member 24 is rotated. become.

Therefore, in the first configuration, the pressing structure c5
By this, at least the relative rotational angular velocity between the first member 21 and the second member 22 can be changed steplessly, and
The ratio of the relative distance between the fulcrum and the force point and the relative distance between the fulcrum and the action point can be changed steplessly. Further, in the first configuration of FIG. 5, the main direction in which the pressing force acts is the direction that does not face the central axis 81, that is, the direction that connects the relative force point and the action point, and the rotation direction.

Next, the second configuration and the second function will be described. When the first member 21 is fixed to the shaft supporting means 90 to have the second structure while being based on the first structure, when the second member 22 transmits a pressing force of one rotation in the rotation direction J1 or j3. , The curved surface q9 pressurizes the third member 23,
The member 23 absorbs the pressurizing force while pressing the elastic member 43, and the third member 23 is stuck between the curved surface q9 and the curved surface q3 of the fourth member 24, and the first member 21 is stuck.
Although the fourth member 24 and the pivotal support means 90 can be pressurized, the pressure applied by the rotation of the second member 22 is the third member 23, the elastic member 43, the first member 21, the fourth member 24, and the pivotal support means. 90
To prevent further rotation of the second member 22, or to prevent the second member 22 from rotating further.
It is also possible to rotate the shaft 4 and the shaft support means 90 substantially once around the central axis 81. In addition, the direction in which the pressing force acts in the second configuration is also generated in the direction described in the first configuration, and the pressing position, which should be the force point and the action point, is also moved relatively.

Next, a description will be given based on the third configuration and the third function. When the second member 22 is fixed to the shaft supporting means 90 to have the third structure based on the first structure, when the first member 22 transmits a pressure force of one rotation in the rotation direction J1 or j3. , The elastic member 43 is pressed in the rotational direction and expands and contracts to absorb the applied pressure, the elastic member 43 presses the third member 23, and the third member 23 presses the curved surface q9 and the curved surface q.
9 and the curved surface q3 of the fourth member 24 can be deadlocked, but the third member 23, the elastic member 43, the second member 22, the shaft and It may be received by the supporting means 90 to prevent further rotation of the first member 22, or the first member 21, the second member 22 and the shaft supporting means 90 may rotate about the central axis 81 about one revolution. It will be possible. In addition, the direction in which the pressing force acts in the third configuration is also generated in the direction described in the first configuration, and the pressing position, which should be the force point and the action point, is relatively moved.

Next, a description will be given based on the fourth configuration and the fourth function. In the case of the fourth configuration, which is based on the first configuration, is provided with a rotation resistance means capable of giving a slight rotation resistance between the first member 21 and the shaft support means 90,
When the pressing force of one rotation is transmitted to the member 22 in the direction of rotation J1 or j3, the pressing force is continuously absorbed between the elastic member 43 and the curved surface q9 as described in the first function, and the third member 23 is absorbed. Then, the first member 21 and the fourth member 24 receive the pressing force and are rotated about once in the rotation direction J1 or j3 with the repulsive force of the absorbed pressing force. Further, while the fourth member 24 is being rotated in the forward direction by the rotation transmission of the second member 22, the first member 22 and the first member 22 are rotated.
Even if the rotation of the member 21 is stopped, the fourth member 24 can continue to rotate in the positive direction. In addition, the direction in which the pressing force acts in the fourth configuration is also generated in the direction described in the first configuration, and the pressure point, which should be the force point and the action point, is relatively moved.

Next, a description will be given based on the fifth configuration and the fifth function. In the case of the fifth configuration in which the fourth member 24 and the pivotal support 90 are connected or fixed or stopped by giving a rotational resistance between the fourth member 24 and the pivotal support 90 while being based on the first configuration. Is the rotation direction J1 or j with respect to the first member 21.
When the pressing force of one rotation is transmitted in the direction of 3, the elastic member 43 and the curved surface q9 absorb the pressing force steplessly and pressurize the third member 23 in the rotating direction as described in the first function, The third member 23 pressurizes the curved surface q9 and the second member 22,
The second member 22 is rotated approximately once in the relative positive direction. However, when the second member 22 is pressed in the direction for rotating the positive member in the positive direction once when the rotational force is not transmitted to the first member 21, the second member 22 as described in the first function is described.
The curved surface q9 pressurizes the third member 23, the third member 23 is sandwiched between the curved surface q3 of the fourth member 24 and the dead end, and the second member 22 does not rotate further. It is also possible to prevent it in stages, or to rotate the second member 22, the first member 21, the fourth member 24, and the shaft support means 90 substantially once about the central axis 81. Further, the working direction of the pressing force in the fifth structure is also generated in the direction described in the first structure, and the pressurizing position, which should become the force point and the working point, are relatively moved.

In any of the above constructions, the first member 2
By receiving the pressurizing force between any one of the first member 2, the second member 22, the third member 23, the fourth member 24, the elastic member 43, and the curved surface q9, the first function and the first configuration are described. Therefore, the relative pressing position is moved, and the ratio of the distance between the action point and the fulcrum to the distance between the fulcrum and the force point is also changed. In addition, in the pressing structure c5 shown in FIG. 5, the cylindrical or cylindrical fourth member 24 having the curved surface q3 on the outer wall surface is provided with the hole w.
It is possible to obtain the above-mentioned numerous functions by inserting the first member 21 and the second member 21 without using the fourth member 24.
This is particularly efficient because rotation transmission between the members 22 in the forward and reverse directions can be freely performed.

FIG. 6 is a schematic view showing a sixth embodiment and features of the speed change structure and the pressurization structure of the present invention capable of showing the plurality of special functions, and FIG. 6 (a) is a front view. FIG. 6B is a diagram showing the right side surface. Further, the speed change structure and the pressurization structure c6 shown in FIG.
Is a structure capable of being relatively rotatably supported about a central shaft 81, and is configured to be rotatable one or more times, and to rotate in either forward or reverse direction. The structure is such that the first member 21 and the second member 22 can be connected so that rotation can be transmitted regardless of which is input.

First, a description will be given based on the first function and the first configuration. In the configuration shown in the figure, the first member 21 and the second member 22
Is rotatably supported relative to the fourth member 24 and the shaft support means 90 about the central shaft 81, respectively.
4 is rotatably supported relative to the first member 21, the second member 22, and the shaft support means 90 about a central shaft 81. Further, the first member 21 has an axis e1 provided with a curved surface q1 formed of an outer wall surface having the same radius with the center axis 81 as the center, and a center axis 82 provided with a distance substantially parallel to the center axis 81. And a hole w2 provided with an inner wall surface q6 having a radius. In addition, the second member 22 has an axis e2 having a curved surface q2 formed of an outer wall surface having the same radius with the center axis 81 as the center, and a center axis 82 having a distance parallel to the center axis 81 and having the same radius as the center. Is connected to a shaft e3 provided with a curved surface q5 composed of the outer wall surface of the above. Further, the fourth member 24 is configured to include a curved surface q3 formed of an outer wall surface having the same radius based on the central axis 81, and a hole w3 having an inner wall surface q7 having the same radius centered on the central axis 81. ing.

Further, the axis e3 of the second member 22 and the first member 2
One hole w2 is fitted, but a bearing be2 made up of a bearing provided with a plurality of cylindrical rolling members 242 is provided between the shaft e3 and the hole w2, and the fourth member 24 is provided with a bearing w2 in the hole w3. The axis e1 of the first member 21 and the axis e2 of the second member 22 are inserted, but the inner wall surface q7 of the fourth member 24
Between the shaft e2 of the member 22, a bearing be1 formed of a rolling bearing provided with a plurality of rolling members 231 is provided. Further, the elastic member 43 is formed by the rolling members 232 and 231.
The rolling members 232 and 2 can be configured as
It is also possible to provide the retainer 31 which is composed of a retaining means for rotatably retaining each of them. Also, the bearing be
The rolling member 232 included in No. 2 and the rolling member 231 included in the bearing be1 can be made to correspond to the third member 23. It should be noted that the third member 23 including the rolling members 232 and 231 may be omitted. The first configuration is established by the above configuration.

When the second member 22 and the fourth member 24 have rotational resistance, when the first member 21 is pressed about the central axis 81 in the rotational direction j1 direction, the first member 21 is rotated with respect to the axis e3.
Is slightly rotated, and the inner wall surface q6 of the hole w2 and the axis e3 are rotated.
Of the rolling member 232 located between the curved surfaces q5 of
6 and the curved surface q5 are pressed while being sandwiched by the relative wedge surfaces, and press the shaft e3 in the rotational direction j1.
The pressing force transmitted from the first member 21 is applied to the rolling member 232.
Then, the second member 22 can receive the second member 22 and rotate at least in the rotation direction j1.

Although not shown in the drawings, the force point and the action point at the pressing position are moved by the central axis 81 while being pressed at a part between the inner wall surface q6 and the curved surface q5 to move the pressing position.
When the fulcrum is used as a fulcrum, the pressing force is transmitted and absorbed while changing the ratio of the relative distance between the force point and the fulcrum and between the action point and the fulcrum. Further, by absorbing the pressing force, it is possible to delay the rotational angular velocity of the second member 22 with respect to the rotational velocity of the first member 21.
After the rotational angular velocity of the second member 22 and the rotational velocity of the second member 22 become the same, the rotational angular velocity of the second member 22 can be made faster than that of the first member 21 by the repulsive force of the elastic member 43 and the relative wedge surface. . Further, since the rolling member 231 is disposed between the second member 22 and the fourth member 24, it is possible to prevent the fourth member 24 from receiving the pressure and not rotating. It should be noted that the bearings be1 and be2, which are provided with the above-mentioned rolling members, can achieve an effect of efficiently performing smooth rotation and receiving the applied pressure.

Next, when the first member 21 is pressurized in the j3 direction, the first member 21 is slightly rotated with respect to the axis e3, and the inner wall surface q6 of the hole w2 and the curved surface q5 of the axis e3 are moved relative to each other. The rolling member 232 located between the wedge surfaces is pressed while being sandwiched between the inner wall surface q6 and the curved surface q5, presses the shaft e3 in the rotational direction j3, and is transmitted from the first member 21. Is received by the rolling member 232 and the second member 22, and at least the second member 22 can rotate in the direction j3 of rotation, and the same function as described above is produced.

Next, when the first member 21 and the fourth member 24 have a rotation resistance, when the second member 22 is pressed about the central axis 81 in the rotation direction j1 direction, the hole w3 of the fourth member 24 is formed.
The shaft e2 and the rolling member 231 are slightly rotated in the
While the shaft e3 is slightly rotated in the hole w2 of the member 21, the inner wall surface q6 of the hole w2 receives the pressing force transmitted from the shaft e3 and the rolling member 232, and the curved surface q1 of the first member 21 corresponds to the fourth member 24. The inner wall surface q7 of the hole w3 is pressed, and the first member 2
It is possible to press the first and fourth members 24 in the rotation direction j1. Therefore, the first member 21 and the fourth member 24 receive the pressing force at least and rotate in the rotation direction j1.

The state of transmission of these rotations depends on the elastic member 43.
The rolling member 242 is compressed so as to be sandwiched between the curved surface q5 of the axis e3 and the inner wall surface q6 of the hole w2 that can be a relative wedge surface while absorbing the pressing force, and the pressing force and the repulsive force. Is the curved surface q1 of the first member 21 and the fourth member 2
It is possible to pressurize between the inner wall surfaces q7 of the holes w1 of 4. Although the force point and the action point which are the pressurizing positions are not illustrated and specifically described, when the central axis 81 is used as the fulcrum, the relative distances between the force point and the fulcrum and between the action point and the fulcrum are shown. There is no change in that the pressure is transmitted and absorbed while the ratio of is changed. For example, in a configuration in which the distance between the force point and the fulcrum and the distance between the action point and the fulcrum are not changed, the fulcrum (the central axis 8
It is limited to the case where both the pressure point and the action point, which are the pressure positions, are at the same distance from the fulcrum with respect to 1) and the positions of the force point and the action point are fixed relative to the fulcrum. The pressure position in the case of each of the other embodiments including this configuration is that the relative arcuate inclined surface or wedge surface is formed, and the position to be the force point and the action point is slipped. It is intended to be changed without fail because it is configured to match or rotate or move relatively.

The first speed relative to the rotation speed of the second member 22
The rotation angular velocities of the member 21 and the fourth member 24 can be delayed, and after the rotation angular velocities of the first member 21, the second member 22, and the fourth member 24 become the same speed, the elastic member 4
It is also possible to make the rotational angular velocities of the first member 21 and the fourth member 24 faster than the second member 22 by the repulsive force of 3 and the relative wedge surface.

Next, when the second member 22 is pressed in the rotational direction j3, the first member 22 and the fourth member 24 receive the applied pressure at least and are rotated in the rotational direction j3. And the same function as described above is generated.

Next, a rotation resistance means capable of imparting rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, and the rotation resistance means is provided around the central axis 81. When the 4 member 24 is rotated in either the normal direction or the reverse direction of the rotation directions j1 and j3, it is not configured to give a large rotation resistance, so at least the first member 21 and the second member 21
The member 22 and the shaft support means 90 cannot receive the pressure applied by the rotation, and only the fourth member 24 is rotated.
Further, in the first configuration of FIG. 6, the main direction in which the pressing force acts is the direction that does not face the central axis 81, that is, the direction that connects the relative force point and the action point, and the rotation direction.

Further, by providing at least the first function shown in the first configuration, the first function to the fifth function and the configuration thereof are hidden as described in the fifth embodiment of FIG. It is the point that will be done. Therefore, any configuration or function can be used freely.

FIG. 7 is a schematic view showing a seventh embodiment and features of the speed change structure and the pressure applying structure of the present invention capable of showing the plurality of special functions, and FIG. 7 (a) is a front view. FIG. 6B is a diagram showing the right side surface. Further, the speed change structure and the pressurization structure c7 shown in FIG.
Is a structure that can be rotatably supported about a central axis 81, is configured to be capable of rotating one or more times, and inputs either the forward or the reverse rotational force from which. Even so, the structure is such that the first member 21 and the second member 22 can be connected so that rotation can be transmitted.

A description will be given based on the first function and the first configuration.
With the configuration shown in the figure, the first member 21 and the second member 22 are rotatably supported relative to the fourth member 24 and the shaft supporting means 90 about the central axis 81, and the fourth member 24 is Central axis 81
Is rotatably supported relative to the first member 21, the second member 22, and the shaft support means 90.

Further, the first member 21 has an axis e1 provided with a curved surface q1 formed of an outer wall surface having the same radius around the central axis 81.
And the central axis 8 which is provided substantially parallel to the central axis 81.
2 is an axis e2 provided with a curved surface q2 formed of an outer wall surface having the same radius, and an inner wall surface q6 having the same radius based on the central axis 81.
Are connected to a circular hole w1. The second member 22 has an axis e3 provided with a curved surface q3 having an outer wall surface with the same radius centered on the central axis 81, and a circular hole w2 provided with an inner wall surface q7 having the same radius centered on the central axis 81. , And a circular hole w3 provided with an inner wall surface q8 of the same radius centered on a central axis 82 which is provided substantially parallel to the central axis 81. Also, the fourth
The member 24 is formed in a cylindrical (or cylindrical) shaft shape having a curved surface q4 having an outer wall surface with the same radius centered on the central axis 81.

Further, the hole w3 of the second member 22 is fitted into the shaft e2, and a bearing be2 consisting of a bearing provided with a plurality of cylindrical rolling members 232 is provided between the shaft e2 and the inner wall surface q8. The hole w2 of the second member 22 and the first
The fourth member 24 is fitted in the hole w1 of the member 21, and a bearing be1 composed of a rolling bearing provided with a plurality of cylindrical rolling members 231 is provided between the hole w2 and the fourth member 24. . Further, the elastic member 43 composed of the first means can be configured as the rolling members 231 and 232, or can be provided in the retainer composed of the holding means for rotatably holding the rolling members 232 and 231 respectively. Further, at least one of the rolling members provided in the bearings be1 and be2 may be the third member 23. Alternatively, the bearings be1 and be2 and the third member 23 including a rolling member may be omitted. The first configuration is established by the above configuration.

When the second member 22 and the fourth member 24 have a rotation resistance, when the first member 21 is pressed in the rotation direction j1 around the central axis 81, the second member 22 and the fourth member 24 are pressed.
On the other hand, the shaft e2 is slightly rotated, and a part of the rolling member 232 located between the inner wall surface q8 of the hole w3 and the relative wedge surface formed by the curved surface q2 of the shaft e2 is located between the inner wall surface q8 and the curved surface q2. The inner wall surface q8 is pressed while being sandwiched by the inner wall surface q8 in the rotation direction j1, and the pressing force transmitted from the first member 21 is used as a wedge surface (curved surface q2 and inner wall surface q8) relative to the rolling member 232. The second member 22 receives the second member 22, and at least the second member 22 can rotate in the j1 direction.

Although illustration of the force point and the action point at the pressurizing position is omitted, when the central axis 81 is used as the fulcrum, the ratio of the relative distances between the force point and the fulcrum and between the action point and the fulcrum. There is no change in that the applied force is transmitted and absorbed while being changed. Further, by absorbing the pressing force, it is possible to delay the rotational angular velocity of the second member 22 with respect to the rotational velocity of the first member 21, so that the rotational angular velocity of the first member 21 and the second member 22 become the same velocity. After that, the repulsive force of the elastic member 43 (rolling member 242) and the relative wedge surface make it possible to increase the rotational angular velocity of the second member 22 faster than the first member 21. Further, since the rolling member 231 is disposed between the second member 22 and the third member 23, it is possible to prevent the fourth member 24 from receiving the applied pressure and not rotating. It should be noted that the bearings be1 and be2 can obtain the effects of efficiently performing smooth rotation and receiving the applied pressure.

Next, when the first member 21 is pressurized in the j3 direction, the pressing force transmitted from the first member 21 is wedged surface (the curved surface q2 and the inner wall surface q8) relative to the rolling member 232 as described above. The second member 22 receives and the second member 22
It is rotated in three directions.

Next, when the first member 21 and the fourth member 24 have rotational resistance, when the second member 22 is pressed about the central axis 81 in the rotation direction j1, the fourth member 24 and the first member 24 are rotated. The second member is slightly rotated with respect to the member 21, so that the rolling member 232 and the curved surface q2 of the first member 21 receive the pressing force transmitted from the inner wall surface q8 of the hole w3 of the second member 22, and the second member The pressing force transmitted from the inner wall surface q7 of the hole w2 of the member 22 presses the curved surface q4 of the fourth member 24, and the pressing force transmitted from the inner wall surface q8 of the hole w3 of the second member 22 is the first.
Since it is possible to pressurize the inner wall surface q6 of the member 21 and the curved surface q4 of the fourth member 24 relatively,
The member 24 can be pressed in the rotation direction j1.
Therefore, the first member 21 and the fourth member 24 receive at least the pressing force and rotate in the j1 direction.

The state of transmission of these rotations is determined by the elastic member 43.
The curved surface q2 and the hole w3 of the axis e2 that can be a relative wedge surface while the rolling member 232 expands and contracts to absorb the applied pressure.
Is pressed so as to be sandwiched between the inner wall surfaces q8 of the first member 21, the pressing force and the repulsive force press the curved surface q2 of the first member 21 in the j1 direction, and the curved surface q4 of the fourth member 24 inside the first member 21. The wall surface q6 can apply pressure in the j1 direction. or,
Although illustration and specific description of the force point and the action point which are the pressurizing positions are omitted, when the central axis 81 is used as the fulcrum, the ratio of the relative distances between the force point and the fulcrum and between the action point and the fulcrum. There is no change in that the applied force is transmitted and absorbed while being changed. Further, it is possible to delay the rotational angular velocities of the first member 21 and the fourth member 24 with respect to the rotational speed of the second member 22, and the first member 21, the second member 22, and the fourth member 24.
After the rotational angular velocities of the first member 21 and the fourth member 24 are made higher than the second member 22 by the repulsive force of the elastic member 43 including the first means and the relative wedge surface. Things are also free.

Next, when the second member 22 is pressurized in the j3 direction, the first member 21 and the fourth member 24 receive the pressing force at least and the first member 21 and the fourth member 24 rotate in the j3 direction. Then, the same function as described above is generated.

Next, a rotation resistance means capable of imparting rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, and a first rotation center means is provided around the center axis 81. 4 member 24 is rotated in either the forward or reverse direction of rotation directions j1 and j3, at least the first member 21
Therefore, the second member 22 and the shaft supporting means 90 cannot receive the pressure applied by the rotation, and only the fourth member 24 is rotated.

Further, in the first configuration of FIG. 7, the main direction in which the pressing force acts is the direction not facing the central axis 81, and the direction connecting the relative force point and the action point, and the rotation direction. Further, by providing at least the first function shown in the first configuration, the first function to the fifth function, and the configuration thereof are hidden, as is apparent from FIG. .

FIG. 8 is a schematic view showing an eighth embodiment and features of the speed change structure and the pressure applying structure of the present invention capable of showing the plurality of special functions, and FIG. 8 (a) is a front view. FIG. 6B is a diagram showing the right side surface. Further, the speed change structure and the pressurization structure c8 shown in FIG.
Reference numeral 1 denotes a structure that can be rotatably supported about a central shaft 81, and is configured to be capable of rotating one or more revolutions. Even if input, the first member 21 and the second member 22 have a structure capable of being connected so that rotation can be transmitted.

A description will be given based on the first function and the first configuration.
In the configuration shown in the figure, although not shown in the drawings, the first member 21 and the second member 22 have a fourth member 24 centered on a central axis 81.
And is rotatably supported relative to the shaft supporting means 90,
The fourth member 24 includes the first member 21 and the second member 24 around the central axis 81.
It is configured to be rotatably supported relative to the member 22 and the shaft support means 90.

Further, the first member 21 is centered on a position at which a distance is provided between the axis e1 provided with a curved surface q1 formed of an arc-shaped outer wall surface having the same radius about the central axis 81 and the central axis 81. It is connected to an axis e2 provided with a curved surface q2 having an outer wall surface protruding in an arc shape having the same radius, and the curved surface q2 forms an arc curved surface from the substantially central axis 81 toward the outer peripheral direction of the first member 21. is doing. Further, the second member 22 has an axis e3 provided with a curved surface q3 formed of an arcuate outer wall surface having the same radius with the central axis 81 as the center, and an axis e3 having the same radius centered on a position provided with a distance from the central axis 81. Is connected to an axis e4 provided with a curved surface q4 formed of an outer peripheral surface protruding in an arc shape,
The curved surface q4 is formed into an arcuate curved surface from the substantially central axis 81 toward the outer peripheral direction of the second member 22. Further, the fourth member 24 is formed in a cylindrical shape having a curved surface q5 formed of an outer wall surface having the same radius about the center axis 81 and a hole w1 formed of an inner wall surface q6 having the same radius based on the center axis 81. ing.

Furthermore, the curved surface q2 of the first member 21 and the curved surface q4 of the second member 22 are positioned so as to be pressurizable in the vicinity of the central axis 81, and the first member 21 and the first member 21 are inserted into the hole w1 of the fourth member 24. Two
The member 22 is inserted and relatively rotatably held.
Further, between the second member 22 and the fourth member 24, a bearing be1 including a bearing provided with a plurality of cylindrical rolling members 231 is provided. Also, the curved surface q
One of 2 and q4 may be formed into a flat surface or a concave arcuate curved surface instead of the convex arcuate curved surface. or,
The curved surfaces q2 and q4 may be considered as relative wedge surfaces. or,
It is also possible to provide any one of the curved surfaces q2 and q4 or the elastic member 43 including the first means of the pressing structure so as to relatively press the curved surfaces q2 and q4. Also, the rolling member 2
31 may be considered as the third member 23 or the elastic member 43. The first configuration is established by the above configuration.

When the second member 22 and the fourth member 24 have a rotational resistance, when the first member 21 is pressed about the central axis 81 in the rotational direction j1 direction, the curved surface q2 serving as a pressing surface becomes the second surface.
The pressurization position is changed while slightly sliding with respect to the curved surface q4 of the member 22, and the curved surface q2 is stuck with respect to the curved surface q4. It can be pressurized to. This causes the rolling member 231 to roll and rotate to the second position.
The curved surface q4 of the member 22 and the elastic member 43 absorb the pressurizing force transmitted from the curved surface q2 of the first member 21 and receive it with a repulsive force, so that the second member 22 rotates in the rotation direction j1.
Will be rotated in the direction of.

In this case as well, when the central axis 81 is assumed to be the fulcrum, the pressurizing position serving as the force point and the action point is the curved surface q.
By the relative sliding movement between 2 and the curved surface q4, the pressing force is transmitted and absorbed while the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the action point and the fulcrum is changed steplessly. Does not change. Further, by absorbing the pressing force, it is possible to delay the rotational angular velocity of the second member 22 with respect to the rotational velocity of the first member 21, so that the rotational angular velocity of the first member 21 and the second member 22 become the same velocity. Elastic member 4 after
By the repulsive force of 3 and the relative wedge surface, the first member 2
It is also possible to increase the rotational angular velocity of the second member 22 faster than 1. Further, since the rolling member 231 is disposed between the second member 22 and the fourth member 24, it is possible to prevent the fourth member 24 from receiving the pressure and not rotating.

Next, when the first member 21 is pressurized in the j3 direction, the second member 22 can receive the pressing force transmitted from the first member 21 in the same manner as described above and rotate.

Next, when the first member 21 and the fourth member 24 have a rotation resistance, when the second member 22 is pressed about the central axis 81 in the rotation direction j1, the fourth member 24 and the first member 24 are rotated. When the second member 22 is slightly rotated with respect to the member 21,
The curved surface q4 of the second member 22 is slightly slid with respect to the curved surface q2 of the member 21, the elastic member 43 expands and contracts to absorb the applied pressure, and the curved surface q4 changes the rotational direction of the curved surface q2 with a repulsive force. The pressure is applied in the relative radial direction (the direction in which the central axis 81 is not connected), and this pressurization causes the curved surface q1 of the first member to change the inner wall surface q6 of the hole w1 of the fourth member 24.
Can be pressurized in the radial direction relative to the direction of rotation.
By this pressurization, the first member 21 and the fourth member 24 are rotated in the rotation direction j1 while receiving the applied pressure.

In this case as well, when the central axis 81 is assumed to be the fulcrum, the pressing position serving as the force point and the action point is the curved surface q.
By the relative sliding movement between 2 and the curved surface q4, the pressing force is transmitted and absorbed while the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the action point and the fulcrum is changed steplessly. Does not change. Further, due to the absorption of the pressing force, the first member 21 and the fourth member 24 are rotated with respect to the rotation speed of the second member 22.
It is possible to delay the rotational angular velocity of the first member 21, the second member 22 and the fourth member 24 after the rotational angular velocity becomes the same speed, the repulsive force of the elastic member 43 and the relative wedge surface. It is also possible to make the rotational angular velocities of the first member 21 and the fourth member 24 faster than the second member 22 by (curved surfaces q2 and q4).

Next, when the second member 22 is pressurized in the j3 direction, the first member 21 and the fourth member 24 receive the pressing force at least and rotate, so that the same function as described above occurs. To be

Next, a rotation resistance means capable of imparting rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, and the rotation resistance means is provided around the central axis 81. 4 member 24 is rotated in either the forward or reverse direction of rotation directions j1 and j3, at least the first member 21
Therefore, the second member 22 and the shaft supporting means 90 cannot receive the pressure applied by the rotation, and only the fourth member 24 is rotated.

Further, in the first configuration of FIG. 8, the main direction in which the pressing force acts is the direction not facing the central axis 81, and the direction connecting the relative force point and the action point, and the rotation direction. In addition, since the first function shown in the first configuration is provided at least, as is clear from FIG. 5, the first function to the fifth function and the configuration thereof are latent. .

FIG. 9 is a schematic view showing the ninth embodiment and features of the speed change structure and pressurization structure of the present invention capable of showing the above-mentioned plurality of special functions, and FIG. 9 (a) is a front view. FIG. 6B is a diagram showing the right side surface. Further, the speed change structure and the pressurization structure c9 shown in FIG.
Is a structure that can be rotatably supported about a central axis 81, is configured to be capable of rotating one or more times, and inputs either the forward or the reverse rotational force from which. Even so, the structure is such that the first member 21 and the second member 22 can be connected so as to be rotatable.

A description will be given based on the first function and the first configuration.
In the configuration shown in the figure, although not shown in the drawings, the second member 22 and the fourth member 24 have the first member 21 centered on the central axis 81.
Is rotatably supported relative to the shaft supporting means 90, and the first member 21 is rotatable relative to the second member 22, the fourth member 24, and the shaft supporting means 90 about the central axis 81. The structure is freely supported.

The first member 21 has a shaft e1 provided with a curved surface q1 composed of an arcuate outer wall surface having the same radius around the center shaft 81, and a diameter smaller than the outer diameters of the shaft e1 and the center shaft 8.
A curved surface q2 composed of arc-shaped outer wall surfaces with the same radius centered on 1
Is connected to an axis e2 provided with a central axis 8
The external gear g3, which is provided with a concave and convex tooth centered on a central axis 82 which is provided at a distance from the central axis 81 and is substantially parallel to the central axis 81.
The external gear g4 is rotatably supported by a small amount, and the external gear g4 engaging or meshing with the external gear g3 is slightly centered on the central shaft 83 provided with a distance substantially parallel to the central shaft 81 and the central shaft 82. It is rotatably supported. Also, the external gear g
3 is provided with a plurality of single teeth at the same radius position around the central axis 82, and the external gear g4 is provided with a plurality of gear teeth at the same radius position around the central axis 83 and the central axis. 8
3 is provided so as not to have the same radius but to have a curved surface q3 protruding from the vicinity of the central axis 83 toward the outside and having an arcuate outer wall surface. The external gear g3 and the external gear g4 are used as the third member 23. The curved surface q3 is a relative wedge surface.

The second member 22 is composed of an external gear g5 meshing with the external gear g3, and has a curved surface q4 formed of an arcuate outer wall surface with the same radius centered on the central shaft 81.
4 are connected. Also, the fourth member 24 is
An axis e5 provided with a curved surface q5 having an arcuate outer wall surface with the same radius around the central axis 81, and a hole w3 provided with an arcuate inner wall surface q6 with the same radius based on the central axis 81 are provided. Is configured.

Further, the curved surface q3, which is a relative wedge surface and is connected to the external gear g4, is arranged so as to be pressurizable with the inner wall surface q6 of the hole w3 to establish the first configuration. The elastic member 43 constitutes the curved surface q3 or the inner wall surface q5, or the pressurizing structure and the speed change mechanism of the present invention shown in FIGS. 2 and 3 are relatively provided between the first member 21 and the second member 22. By being provided with the configuration, the effective effects described with reference to FIG. 2 and FIG. 3 can be obtained.

When the second member 22 and the fourth member 24 have a rotation resistance and the first member 21 is pressed in the rotation direction j1 around the central axis 81, the curved surface q3 slightly adds the inner wall surface q6. Although pressed, the external gear q4 can press the external gear q3 in the rotational direction, and the external gear g3 can press the external gear g5 in the rotational direction. Therefore, the second member 22 receives the pressing force transmitted from the first member 21 and rotates in the rotation direction j1. Also in this case, the first member 21 and the second member 21
When the pressurizing structure and the speed change mechanism of the present invention described in FIGS. 2 and 3 are relatively provided between the members 22, absorption of the pressing force, the distance between the force point and the fulcrum, and the point between the action point and the fulcrum There is no change in that the pressure force is transmitted and absorbed while the ratio of the relative distance to the distance is continuously changed. Also, the elastic member 43
It is possible to delay the rotational angular velocity of the second member 22 with respect to the rotational velocity of the first member 21 by absorbing the pressure force on the relative wedge surface.
After the rotational angular velocity of the member 22 reaches the same velocity, the repulsive force of the elastic member 43 and the relative wedge surface cause the first member 2 to rotate.
It is also possible to increase the rotational angular velocity of the second member 22 faster than 1. If the rotational resistance due to the pressing force and sliding friction between the second member 22 and the fourth member 24 is small, the fourth member 2
It is also possible that 4 cannot receive the applied pressure and cannot rotate.

Next, when the first member 21 is pressed in the j3 direction, the second member 22 can receive the pressing force transmitted from the first member 21 in the same manner as described above and rotate.

Next, when the first member 21 and the fourth member 24 have rotational resistance, when the second member 22 is pressed around the central shaft 81 in the rotational direction j1 direction, the external gear g5 causes the external gear g5 to rotate.
3, the external gear g3 is slightly rotated about the central axis 83 of the external gear g4 in the rotation direction j5 direction, and the curved surface q3 can press the inner wall surface q6. By this pressurization, the curved surface q3 can press the inner wall surface q6 of the hole w3 of the fourth member 24 in the radial direction (direction not connecting the central axis 81) relative to the rotation direction, and at the same time as the first member 21. The fourth member 24 receives the applied pressure and is rotated in the rotation direction j1 with a repulsive force. Even in this case, the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the action point and the fulcrum is changed steplessly, and the pressing force is transmitted and absorbed.

Also, the second member 22 is absorbed by absorbing the applied pressure.
It is possible to delay the rotational angular velocities of the first member 21 and the fourth member 24 with respect to the rotational speed of No. 1, and the rotational angular velocities of the first member 21, the second member 22 and the fourth member 24 become the same speed. After that, the rotational angular velocities of the first member 21 and the fourth member 24 can be made faster than the second member 22 by the repulsive force of the elastic member 43 and the relative wedge surfaces (the curved surface q3 and the inner wall surface q6).

Next, when the second member 22 is pressed in the direction of rotation j3, the first member 21 and the fourth member 24 receive at least the pressing force and are rotated in the direction of rotation j3. And a function similar to the above is produced.

Next, a rotation resistance means capable of providing rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, and the rotation resistance means is provided around the central axis 81. 4 member 24 is rotated in either the forward or reverse direction of rotation directions j1 and j3, at least the first member 21
Therefore, the second member 22 and the shaft supporting means 90 cannot receive the pressure applied by the rotation, and only the fourth member 24 is rotated.

Further, in the first configuration of FIG. 9, the main direction in which the pressing force acts is the direction not facing the central axis 81, and the direction connecting the relative force point and the action point, and the rotation direction. In addition, since the first function shown in the first configuration is provided at least, as is clear from FIG. 5, the first function to the fifth function and the configuration thereof are latent. .

FIG. 10 is a schematic view showing the tenth embodiment and features of the speed change structure and the pressurizing structure of the present invention capable of showing the plurality of special functions, and FIG. 10 (a) is a front view. FIG. 6B is a diagram showing the right side surface. Further, the speed change structure and the pressurization structure c10 shown in FIG.

An axis e5 having a smaller diameter than the outer diameter of 1 and provided with a curved surface q5 formed of an arc-shaped outer wall surface having the same radius about the central axis 81.
And a circular hole w1 is provided at a position where a distance is provided substantially parallel to the central axis 81, and a cylindrical elastic member 43 is provided in the hole w1. The rotary shaft 31 is rotatably supported about the central shaft 82, though slightly, and an external gear g4 meshing with the external gear g3 is coupled to the rotary shaft 31 at one end of the rotary shaft 31, and the shaft e1 is interposed therebetween. At the other end of the rotary shaft 31, a third member 23 having a curved surface q4 composed of an arcuate outer surface (which may be a flat surface) not centered on the central shaft 82 is connected to the rotary shaft 31. There is.

In addition, the third part including the rotary shaft 31 and the external gear g4
The member 23 can also be used. Further, the curved surface q4 has a central axis 82
Is a relative wedge surface that is formed by an arcuate surface that passes through, and is a surface that is connected from a position approaching the central axis 82 to a position distant from it. Further, the curved surface q4 of the third member 23 and the curved surface q3 of the fourth member 24 are connected so as to be pressurizable in the vicinity of the central axis 82 to establish the first configuration.

When the second member 22 and the fourth member 24 have a rotation resistance, when the first member 21 is pressed in the rotation direction j1 about the central axis 81, the inner wall surface of the hole w2 of the elastic member 43 becomes While the pressing force is absorbed in the rotating direction of the rotating shaft 31 and the repulsive force is absorbed, the curved surface q4 connected to the rotating shaft 31 and the curved surface q3 of the fourth member 24 are slightly pressed, The external gear g4 is the second member 2 including the external gear g3.
2 can be pressed and rotated in the rotation direction j1.

In this pressure-applied state, the pressing force acts in a direction that does not face the central axis 81, and the external gear g3
The third member 23 including the external gear g4 meshing with the central shaft 8
1 is moved (moved) by being relatively pressurized in the illustrated j2 direction which is inclined relative to 1, and the central axis 8
The pressure is applied in the illustrated j4 direction having a relative angle with respect to 1, and is combined with a direction away from the central axis 81 or a direction approaching the central axis 81 and a direction rotated about the central axis 81. It will be pressurized in different directions. By this pressurization, the elastic member 43 expands and contracts, the meshing of the teeth between the external gear g3 and the external gear g4 is strengthened, and the meshing pitch position between the external gear g3 and the external gear g4 is changed from a normal position to an inappropriate position. Then, the meshing position between the external gear g3 and the external gear g4 is moved in the outer peripheral direction of the external gear g3, and the central shaft 81
The relative position, which is to be the force point and the action point with the fulcrum as the fulcrum, is moved to the meshing position between the external gear g3 and the external gear g4, and the ratio of the relative distance between the fulcrum and the action point with respect to the distance between the fulcrum and the force point. As a result, the pressing force of the first member 21 is relatively received between the elastic member 43, the curved surface q4, and the second member 22, and the second member 22 is rotated in the rotation direction j1.

Further, by absorbing the applied pressure, the first member 21
It is possible to delay the rotation angular velocity of the second member 22 with respect to the rotation speed of the first member 21, and after the rotation angular velocity of the first member 21 and the second member 22 become the same speed, the repulsive force of the elastic member 43 and the above-mentioned It is also possible to make the rotational angular velocity of the second member 22 faster than the first member 21 by the relative wedge surface. Further, if the pressing force between the curved surface q4 of the third member 23 and the curved surface q3 of the fourth member 24 and the rotation resistance due to sliding friction are small, the fourth member 24 cannot receive the pressing force and can be prevented from rotating. is there.

Next, when the first member 21 is pressurized in the j3 direction, the second member 22 receives the pressing force transmitted from the first member 21 and rotates in the rotation direction j3 shown in the figure, as described above. I can do things.

Next, when the first member 21 and the fourth member 24 have a rotation resistance, when the second member 22 is pressed about the central axis 81 in the rotation direction j1, the elastic member 43 exerts a pressing force. The curved surface q4 of the third member 23 presses the curved surface q3 of the fourth member 24 while the external gear g4 moves in a direction away from the central axis 81 while absorbing and absorbing, and the relative wedge surfaces (curved surface q3 and curved surface q4). The first member 2 is stuck due to
The first and fourth members 24 are rotated while being pressed in the rotation direction j1. The direction in which the pressing force acts at this time is also the composite direction described above. Even in this case, the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the action point and the fulcrum is changed steplessly, and the pressing force is transmitted and absorbed. In addition, it is possible to delay the rotational angular velocities of the first member 21 and the fourth member 24 with respect to the rotational velocity of the second member 22 by absorbing the pressing force. After the rotational angular velocities of the four members 24 become equal to each other, the repulsive force of the elastic member 43 and the relative wedge surface cause the second member 22 to move to the first position.
It is also possible to increase the rotational angular velocities of the member 21 and the fourth member 24.

Next, when the second member 22 is pressed in the j3 direction, the first member 21 and the fourth member 24 receive the applied pressure at least and rotate, so that the same function as described above occurs. To be

Next, a rotation resistance means capable of imparting rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, and the rotation resistance means is provided around the central axis 81. When the four member 24 is rotated in any of the rotation directions j1 and j3, at least the first member 21 and the second member
The member 22 and the shaft support means 90 cannot receive the pressure applied by the rotation, and only the fourth member 24 is rotated.

Further, by providing at least the first function shown in the first configuration, as has been made clear in FIG. 5 and the fifth embodiment, at least the first function to the fifth function, and It is the main idea that the structure is latent. Further, in any of the first to fifth configurations, the directions in which the pressing force is generated when the rotational pressing force is received are the above-described composite directions and are concentrated on the central axis 81 at least. Not a thing. Therefore, it is possible to prevent the member that is rotated around the central shaft 81 from being pressurized intensively and ensure the safety.

6 and 6 are slightly pressed, and the external gear g4 can press the internal gear g7 in the rotational direction. In this pressurizing state, the pressing force acts in a direction that does not face the central axis 81, and the third member 23 including the external gear g4 meshing with the internal gear g7 and the rotary sleeve 31 is fixed to the central axis 81. In addition to being moved (movable) by being relatively pressed in the illustrated j2 direction that is relatively inclined with respect to the illustrated, and being pressed in the illustrated j4 direction that has a relative angle with respect to the central axis 81, Central axis 81
The pressure is applied in a direction away from the center axis 81 or in a direction approaching the central axis 81, and is applied in a combined direction with a direction rotated about the central axis 81.

By this pressurization, the elastic member 43 expands and contracts, the meshing of the teeth between the external gear g4 and the internal gear g7 is strengthened, and the meshing pitch position of the teeth between the external gear g4 and the internal gear g7 becomes incorrect from the normal position. It becomes the proper position and the external gear g
4 and the internal gear g7 are moved so that the meshing position between them is the inner peripheral direction of the internal gear g7 and is closer to the central shaft 81,
When the central axis 81 is used as the fulcrum, the relative position of the pressurization to be the force point and the action point is moved, and the ratio of the relative distance between the fulcrum and the action point is changed with respect to the distance between the fulcrum and the action point, while the first member is being changed. The pressing force of 21 is relatively received between the elastic member 43, the third member 23, and the second member 22, and the second member 22
Is rotated in the rotation direction j1.

It is possible to delay the rotation angular velocity of the second member 22 with respect to the rotation speed of the first member 21, and after the rotation angular velocity of the first member 21 and the second member 22 become the same speed, the repulsive force of the elastic member 43 and the above-mentioned First by the relative wedge surface (curved surface q4)
It is also possible to make the rotational angular velocity of the second member 22 faster than the member 21. Further, if the pressing force between the curved surface q4 of the third member 23 and the inner wall surface q6 of the fourth member 24 and the rotation resistance due to sliding friction are small, the fourth member 24 cannot receive the pressing force and can be prevented from rotating. Is.

Next, when the first member 21 is pressurized in the j3 direction, the second member 22 receives the pressing force transmitted from the first member 21 and rotates in the j3 direction shown in the figure in the same manner as described above. it can.

Further, in the speed change structure and the pressurization structure c12 shown in the figure, the first member 21 and the second member 22 have the central shaft 81
It is a structure that can be rotatably supported around a center, and each is configured to be capable of rotating one or more times. The member 21 and the second member 22 have a structure capable of being connected so that rotation can be transmitted.

A description will be given based on the first function and the first configuration.
In the configuration shown in the figure, although not shown in the drawings, the first member 21 and the fourth member 24 have the second member 22 centered on the central axis 81.
And is rotatably supported relative to the shaft supporting means 90,
The second member 22 is arranged with the first member 21 and the fourth member 21 about the central axis 81.
The member 24 and the shaft supporting means 90 are rotatably supported relative to each other.

The second member 22 is provided with a curved surface q2 (which may be a flat surface) which is rotatable about the central axis 81 and which is a concave hole in an arc shape. Is connected to a cylindrical shaft e4 formed of the outer wall surface. In addition, the fourth member 24 is configured by connecting an internal gear g7 having a plurality of uneven teeth so as to surround the central shaft 81 and a cylindrical shaft.

Further, the first member 21 is provided with a circular hole w1 at a position where a distance is provided substantially parallel to the central axis 81 on a cylindrical axis formed of an arcuate outer wall surface with the central axis 81 as the center. At the same time, a cylindrical elastic member 43 is arranged in the hole w1, and the cylindrical rotary shaft 31 is rotatably held in the hole w2 of the elastic member 43 about the central shaft 82. An external gear g4 and an external gear g5, which are provided with uneven teeth that mesh with the internal gear g7, are connected to the rotating shaft 31.

The external gear g4 and the external gear g5 are connected to the rotary shaft 31.
The outer diameter is larger than the radius of the.
The rotation shaft 31, the external gear g4, and the external gear g5 are included in the third
The member 23 can also be used. The curved surface q2 is a relative wedge surface. Further, the curved surface q2 of the second member 22 and the outer wall surface of the rotary shaft 31 of the third member 23 are pressurizedly connected to each other to establish the first configuration.

When the second member 22 and the fourth member 24 have rotational resistance, when the first member 21 is pressed in the rotation direction j1 about the central axis 81, the inner wall surface of the hole w2 of the elastic member 43 is The outer wall surface of the rotating shaft 31 presses the curved surface q2 of the second member 22 in the rotating direction while absorbing the pressurizing force while pressing the rotating shaft 31 in the rotating direction and accommodating the repulsive force. The teeth (outer wall surface) are the teeth (inner wall surface) of the internal gear g7.
It is possible to apply a slight pressure. In this pressurized state, the pressing force acts in a direction that does not face the central shaft 81, and the third member 23 including the external gears g4 and g5 meshing with the internal gear g7 and the rotary shaft 31 is the central shaft. It is moved (moved) by being relatively pressed in the illustrated j2 direction which is inclined relative to 81, and is also pressed in the illustrated j4 direction having a relative angle with respect to the central axis 81. With
The pressure is applied in a direction away from the central axis 81 or in a direction approaching the central axis 81, and a pressure is applied in a composite direction with a direction rotated about the central axis 81. By this pressurization, the elastic member 43 expands and contracts, the meshing between the teeth and surfaces of the external gears g4 and g5 and the internal gear g7 and the applied pressure are strengthened, and the meshing pitch of the teeth between the external gears g4 and g5 and the internal gear g7 is further increased. From the normal position to the inappropriate position, the meshing position of the external gears g4 and g5 and the internal gear g7 becomes the central shaft 8.
When the center axis 81 is moved as a fulcrum by moving in a direction away from 1, the relative position of the pressurization to be the force point and the action point is moved, and the relative distance between the fulcrum and the action point is relative to the distance between the fulcrum and the action point. The pressing force of the first member 21 is relatively received between the elastic member 43, the third member 23, and the second member 22 while the ratio of is changed, and the second member 22 is rotated in the rotation direction j1 direction. become.

Further, by absorbing the applied pressure, the first member 21
It is possible to delay the rotational angular velocity of the second member 22 with respect to the rotational speed of the first member 21, and after the rotational angular velocity of the first member 21 and the second member 22 become the same speed, relative to the repulsive force of the elastic member 43. It is also possible to make the rotational angular velocity of the second member 22 faster than the first member 21 by means of the general wedge surface (curved surface q4). Further, since the external gears g4 and g5 can roll and rotate on the tooth surface of the internal gear g7, if the resistance is small, the fourth member 2
It is also possible to prevent the internal gear g7 composed of 4 from rotating because it cannot receive the pressing force.

Next, when the first member 21 is pressed in the j3 direction, the pressing force transmitted from the first member 21 can be received by the second member 22 and rotated in the j3 direction as shown in the same manner as described above. .

Next, when the first member 21 and the fourth member 24 have rotational resistance, the second member 22 is pressed in the rotational direction j1 direction, and the curved surface q2 causes the rotating shaft 31 and the external gears g4 and g5.
Is pressed in a direction further away from the central axis 81, and the elastic member 4
3, the external gears g4 and g5 are pressed against the internal gear g7 and the external gears g4 and g5 strengthen the meshing with the internal gear g7, while the external gears g4 and g5 are between the internal gear g7. The meshing of the teeth is changed from the normal pitch position to the inappropriate pitch position, and the external gears g4 and g5 move to the central shaft 8
1, the external gears g4 and g5, and the internal gear g7 cannot move relative to each other after being moved in the direction away from 1, and the pressing force transmitted from the second member 22 is transferred to the curved surface q2 and the rotary shaft 3
The first member 21 and the fourth member 24 are rotated in the rotation direction j1 while being received by the gear 1, the external gear g4, g5, and the internal gear g7. The direction in which the pressing force acts at this time is also the composite direction described above. Even in this case, the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the action point and the fulcrum is changed steplessly, and the pressing force is transmitted and absorbed. Also, by absorbing the applied pressure,
It is possible to delay the rotational angular velocities of the first member 21 and the fourth member 24 with respect to the rotational speed of the second member 22, and the rotational angular velocities of the first member 21, the second member 22 and the first member 24 are the same. After reaching the speed, the rotational angular speeds of the first member 21 and the fourth member 24 can be made faster than the second member 22 by the repulsive force of the elastic member 43 and the relative wedge surface (curved surface q2).

Next, when the second member 22 is pressurized in the j3 direction, the first member 21 and the fourth member 24 receive the pressing force at least and rotate, so that the same function as described above occurs. To be

Next, a rotation resistance means capable of imparting rotation resistance is provided between at least one of the first member 21 and the second member 22 and the shaft support means 90, and the rotation resistance means is provided around the central shaft 81. 4 member 24 is rotated in either the forward or reverse direction of rotation directions j1 and j3, at least the first member 21
The second member 22 and the shaft supporting means 90 cannot receive the pressure applied by the rotation, the third member 23 is rotated about the central axis 32, and the fourth member 24 is rotated about the central axis 81. It will be a matter.

Further, by providing at least the first function shown in the first configuration, the first function to the fifth function, and the configuration thereof are hidden as described in FIG. 5 and the fifth embodiment. It is the purpose. Further, in any of the first to fifth configurations, the direction in which the pressing force is generated when the rotational pressing force is received is the above-described composite direction and is concentrated on the central axis 81 at least. Not a thing.

The above is the embodiment of the speed change structure and the pressure structure according to the basic structure A of the present invention.

The following embodiments are a speed change structure and a pressurizing structure according to the present invention, and have a structure having a function partially different from the function hidden in the basic structure A. Further, the structure including the first means and the second means of the pressurizing structure clarified in the first, second, third, fourth and fifth embodiments is the same.

FIG. 13 is a schematic view showing a thirteenth embodiment and features of the speed change structure and pressurizing structure of the present invention capable of showing a plurality of special functions, and FIG. 13 (a) is a front view. (B) is a figure which shows a right side surface. Further, the speed change structure and the pressurization structure c13 shown in FIG.
Reference numeral 2 denotes a structure that can be rotatably supported about a central axis 81, and is configured to be rotatable one or more times. Even if input, the first member 21 and the second member 22 have a structure capable of being connected so that rotation can be transmitted.

First, the basic structure A will be described based on the first function and the first configuration. In the configuration shown in the figure, although not shown in the drawings, the first member 21 and the second member 22 are rotatable relative to the fourth member 24 and the pivotal support means 90 about the central axis 81. The fourth member 24 is pivotally supported and the central shaft 8
1, the first member 21, the second member 22, and the pivotal support means 90
It is configured to be rotatably supported relative to.

The first member 21 includes an external gear g3 rotatable about the central shaft 81 and a cylindrical shaft e1 provided with an arcuate outer wall surface having the same radius about the central shaft 81. It is configured by being connected. Further, the second member 22 has the central shaft 8
1 and a cylindrical shaft e provided with an outer gear wheel g4 rotatable about 1 and an arcuate outer wall surface having the same radius around the central shaft 81.
It is configured by connecting 2 and.

The fourth member 24 has an axis e3 composed of an arcuate outer wall surface having the same radius about the central axis 81, and the axis e3.
3, which is smaller than the outer diameter of 3 and is connected to an axis e5 formed of an arc-shaped outer wall surface having the same radius around the central axis 81, and a circular hole w1 is provided at a position spaced from the central axis 81. At the same time, an arcuate elastic member 43 is fitted in the hole w1 as shown in the drawing, and the rotary shaft 31 is rotatably held in the hole w2 of the elastic member 43 about the central shaft 82 and is rotatable relative to the central shaft 81. Inclined j2 direction and central axis 8
It is held so as to be slightly rotatable in the illustrated j4 direction having a relative angle with respect to 1. An external gear g5 that meshes with the external gear g3 is connected (fixed) to the rotating shaft 31 at one end of the rotating shaft 31, and an external gear g5 is connected to the other end of the rotating shaft 31 with the shaft e3 in between. An external gear g6 that meshes with the gear g4 is connected to the rotating shaft 31.

Further, the relative wedge surface in this construction is the angle of the tooth surface of the teeth of the external gears g1, g2, g3 and g4 (for example, the angle of inclination of the tooth surface is 20 °).
In addition, since the teeth of the concavities and convexities of each external gear have a relative angle (the pressure angle provided for the meshing teeth), they can play a wedge-like role. In addition, the third member 23 is the rotating shaft 31.
And the external gear g5 and the external gear g6. The first configuration is established by these configurations.

Further, the number of teeth of the external gear g3 used here is 16
The number of teeth of the external gear g4 is 18, the number of teeth of the external gear g5 is 18, and the number of teeth of the external gear g6 is 16. However, the number of teeth can be set freely. I can do things.

When the first member 21 is pressed in the direction of rotation j1 when the second member 22 has a rotational resistance, the external gear g5 is moved by the relative wedge surface (the pressure angle of the teeth).
A composite of a direction of j2-1 illustrated with respect to the central axis 81 with the inner wall surface of the hole w2 as a fulcrum, and a direction of j4-1 illustrated with a relative angle with respect to the direction of the rotation direction j1. In this direction, the external gear g6 is slightly pressurized and slightly moved, and the external gear g6 is tilted with respect to the central axis 81 about the inner wall surface of the hole w2 as a fulcrum. Is moved at least slightly in a combined direction with the direction of j4-2 shown in the drawing having a relative angle with respect to. As a result, the teeth of the external gear g3 and the external gear g5 and the teeth of the external gear g4 and the external gear g6 slightly mesh with each other while firmly meshing with each other while slightly moving in the meshing position, and the teeth at the meshing portion are pressed together. The two members are restrained (locked) by a frictional force and a pressing force, and when the first member 21 is rotated once, the pressing force transmitted from the first member 21 is received and the second member 22 and the fourth member 24 are in the same direction. It is possible to make about one rotation.

Further, due to the transmission of the pressing force of this rotation, the elastic member 43 near the rotary shaft 31 is expanded and contracted while accommodating the repulsive force and absorbs the pressing force, and the meshing position of the external gears is in the central axis 81 direction. When the central axis 81 is used as the fulcrum, the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the fulcrum and the action point can be changed by approaching or leaving the center axis 81. Therefore, as described in each of the above-described embodiments, the rotational angular velocities of the second member 22 and the fourth member 24 can be slightly delayed with respect to the rotational speed of the first member 21 by absorbing the pressing force. , The first member 21
After the rotational angular velocities of the second member 22 and the fourth member 24 become equal to each other, the repulsive force of the elastic member 43 and the relative wedge surface (pressure angle of gear teeth) cause
It is also possible to increase the rotational angular velocities of the member 22 and the fourth member 24.

Next, the first member 21 is pressed in the j3 direction to
When rotated, the first member 2 has the same function as described above.
Even if the pressing force transmitted from 1 is small, the elastic member 43, the external gears g5 and g6, the rotation shaft 31, and the external gear g4 including the second member 22 receive the second member 22 and the fourth member 24, and the second member 22 and the fourth member 24 are shown by j3 in FIG. It is possible to make about one rotation in the direction.

Next, when the first member 21 has a rotation resistance, the second member 22 is pressed in the direction of rotation j1 and rotated once, and is transmitted from the second member 22 by a function substantially similar to the above. Even if the applied pressure is small, the elastic member 43, the external gears g5 and g6, the rotation shaft 31, and the external gear g3 including the first member 21 receive the first member 21 and the fourth member 24 in the direction j1 shown in FIG. Can rotate.

Next, the second member 22 is pressed in the j3 direction to 1
When rotated, the second member 2 has the same function as described above.
Even if the pressing force transmitted from 2 is small, the elastic member 43, the external gears g5 and g6, the rotating shaft 31, and the first member 21 receive the first member 21 and the fourth member 24 in the j3 direction shown in the figure.
Can rotate.

Next, when the fourth member 24 is fixed to the shaft supporting means 90 and the fourth member 24 and the shaft supporting means 90 are not rotated, when the second member 22 has a rotation resistance, When one member 21 is rotated once in the rotation direction j1, the second member 22 is rotated about 64/81 in the rotation direction j1 when calculated based on the number of teeth. or,
When the second member 22 is rotated once in the rotation direction j1 when the first member 21 has a rotation resistance, the first member 21 is rotated about 81/64 in the rotation direction j1. The pressing force is absorbed while accompanied by the repulsive force of the pressing force similar to the above, and the direction in which the pressing force works is also substantially the same as the above.

Next, when the first member 21 is fixed to the shaft supporting means 90 and the first member 21 and the shaft supporting means 90 are not rotated, when the second member 22 has a rotation resistance, When the four member 24 is rotated once in the rotation direction j1, the second member 22 is rotated about 17/81 in the rotation direction j1 when calculated based on the number of teeth. However, in this state, when the rotation of the fourth member 24 is stopped (may be rotated) and the second member 23 is pressurized to rotate in the direction j1 or the direction j3, The direction in which the pressing force acts is not in the direction of the central axis 81, and the external gears g5 and g6 are at least inclined with respect to the central axis 81 and have a relative angle with respect to the central axis 81. Is applied in a complex direction, the meshing pitch between the external gears becomes an inappropriate position, and the external gear g3 fixed to the external gear g5 is strengthened in meshing and receives a pressurizing force to be restrained (locked). Therefore, the external gear g5 cannot roll and rotate on the tooth surface of the external gear g3, and the relative rotation of the second member 22 with respect to the first member 21 is prevented.
In this case as well, the pressing force is absorbed steplessly by the elastic member 43 and the relative wedge surface.

Next, when the second member 22 is fixed to the shaft supporting means 90 and the second member 22 and the shaft supporting means 90 are not rotated, the first member 21 has a rotational resistance when the first member 21 has a rotation resistance. When the four members 24 are rotated once in the rotation direction j1, the first member 21 is rotated about 17/64 in the direction opposite to the rotation direction j1 when calculated based on the number of teeth. However, in this state, if the rotation of the fourth member 24 is stopped (may be rotated) and the first member 21 is pressed to rotate in the rotation direction j1 or the rotation direction j3, The direction in which the pressure acts is a direction that does not face the direction of the central axis 81, and the external gears g5 and g6 are at least a combination of a direction inclined with respect to the central axis 81 and a direction having a relative angle with respect to the central axis 81. In the appropriate direction, the meshing pitch between the external gears becomes an inappropriate position, and the external gear g6
The external gear g4, which is fixed to the second member 22, is prevented from rolling and rotating on the tooth surface of the external gear g4 because the meshing of the external gear g4 is strengthened and the pressing force is received and restrained. The relative rotation of 21 will be blocked. In this case as well, the pressing force is absorbed steplessly by the elastic member 43 and the relative wedge surface.

In addition, the structure of FIG. 13 has various latent functions and structures, and any of the various functions and structures can be utilized. Further, in any of the configurations including the first configuration, the directions in which the pressing force is generated when receiving the pressing force of the rotation are the above-described composite directions and are not concentrated on the central axis 81 at least.

FIG. 14 is a schematic view showing the features and features of a speed change structure and a pressurizing structure of the present invention capable of showing a plurality of special functions, and FIG. 14 (a) is a front view. (B) is a figure which shows a right side surface. Further, the speed change structure and the pressurization structure c14 shown in FIG.
Reference numeral 2 denotes a structure that can be rotatably supported about a central axis 81, and is configured to be rotatable one or more times. Even if input, the first member 21 and the second member 22 have a structure capable of being connected so that rotation can be transmitted.

First, a description will be given based on the first function and the first configuration. In the configuration shown in FIG.
The member 21 and the second member 22 are rotatably supported about the central shaft 81 relative to the fourth member 24 and the shaft support means 90, and the fourth member 24 is the first member about the central shaft 81. 21, the second member 22, and the pivotal support means 90 are rotatably supported relative to each other.

The first member 21 is rotatable about the central axis 81 and has an internal gear g7 having a plurality of concave and convex teeth, and an arcuate outer wall surface having the same radius about the central axis 81. Is connected to a cylindrical shaft e1. The second member 22 is rotatable about the central axis 81 and has an internal gear g8 having a plurality of concave and convex teeth.
And a cylindrical shaft e2 having an arcuate outer wall surface with the same radius centered on the central axis 81.

The fourth member 24 has an axis e3 formed of an arcuate outer wall surface having the same radius about the central axis 81, and the axis e.
3 has a smaller diameter than the outer diameter of 3 and has an axis e5 formed of an arc-shaped outer wall surface having the same radius with the central axis 81 as the center.
1 is provided with a hole w1 formed by cutting the outer wall surface of the shaft e3 at a position spaced apart from the shaft e3, and a U-shaped elastic member 43 is provided in the hole w1. The rotary shaft 31 is rotatably held about the center of the shaft, and is rotatably held in the illustrated j2 direction inclined with respect to the central shaft 81 and the illustrated j4 direction having a relative angle with respect to the central shaft 81. . Also, an external gear g3 having a plurality of concave and convex teeth that mesh with the internal gear g7 is connected (fixed) to the rotary shaft 31 at one end of the rotary shaft 31, and the rotary shaft 31 is provided with the shaft e3 in between. An external gear g4 having a plurality of uneven teeth meshing with the internal gear g8 is provided at the other end of the rotary shaft 31.
Are linked to.

Further, the relative wedge surface in this configuration is the inclination angle (for example, a pressure angle of 20 °) of the tooth flanks of the concavo-convex teeth of the internal gears g7 and g8 and the external gears g3 and g4.
In addition, since the uneven teeth have a relative inclination angle (a pressure angle provided for meshing teeth), they can play a wedge-like surface role. Further, the third member 23 can be the rotating shaft 31, the external gear g3, and the external gear g4. The first configuration is established by these configurations.

The number of teeth of the internal gear g7 used here is 60
The internal gear g8 has 62 teeth, the external gear g3 has 20 teeth, and the external gear g4 has 22 teeth.

When the first member 21 is pressed in the rotational direction j1 when the second member 22 has a rotational resistance, the external gear g3 is caused by the relative wedge surface (the pressure angle of the teeth).
A composite of a direction of j2-1 illustrated with respect to the central axis 81 with the inner wall surface of the hole w2 as a fulcrum, and a direction of j4-1 illustrated with a relative angle with respect to the direction of the rotation direction j1. The external gear g4
Is a composite of the direction of j2-2 illustrated with respect to the central axis 81 with the inner wall surface of the hole w2 as a fulcrum, and the direction of j4-2 illustrated with a relative angle to the direction of the rotation direction j1. The teeth of the internal gear g7 and the external gear g3 and the teeth of the internal gear g8 and the external gear g4 are firmly meshed while moving in the meshing position by being pressurized and moved at least in the desired direction. When the first member 21 is rotated once because the teeth in the meshing portion are constrained (locked) by the relative pressure, the second member 22 receives the applied pressure and the fourth member 24.
At the same time, it is possible to make about one rotation in the same direction.

By the transmission of the pressing force of this rotation, the elastic member 43 near the rotary shaft 31 expands and contracts with the repulsive force to absorb the pressing force, and the meshing position between the external gear and the internal gear is changed. When the central axis 81 is used as a fulcrum, the ratio of the relative distance between the distance between the force point and the fulcrum and the distance between the fulcrum and the action point can be changed by moving the central axis 81 closer to or away from the central axis 81. it can. That is, the meshing pitch of the gears may be changed to an inappropriate position.
Therefore, as described in each of the above-described embodiments, the rotational angular velocities of the second member 22 and the fourth member 24 can be slightly delayed with respect to the rotational speed of the first member 21 by absorbing the pressing force. After the rotational angular velocities of the first member 21, the second member 22, and the fourth member 24 become the same, the repulsive force of the elastic member 43 and the relative wedge surface (pressure angle of the gear teeth) cause the first It is also possible to make the rotational angular velocities of the second member 22 and the fourth member 24 faster than the member 21.

Next, the first member 21 is pressed in the j3 direction to
When rotated, the elastic member 43, the external gears g3 and g4, the rotation shaft 31, and the second member 22 receive the second member by a function substantially similar to the above, even if the pressing force transmitted from the first member 21 is small. 22 and the fourth member 24 are 1 in the j3 direction shown.
Can rotate.

Next, when the first member 21 has a rotation resistance, the second member 22 is pressed in the rotation direction j1 direction and rotated once, and is transmitted from the second member 22 by a function substantially similar to the above. Even if the applied pressure is small, the elastic member 43, the external gears g3 and g4, the rotary shaft 31, and the first member 21 receive the first member 21 and the fourth member 24 so that the first member 21 and the fourth member 24 can rotate once in the j1 direction.

Next, the second member 22 is pressurized in the j3 direction to 1
When rotated, the elastic member 43, the external gears g3 and g4, the rotary shaft 31, and the first member 21 receive the first member 21 by a function substantially similar to the above, even if the pressing force transmitted from the second member 22 is small. 21 and the 4th member 24 are 1 in the j3 direction of illustration.
Can rotate.

Next, when the fourth member 24 is fixed to the shaft supporting means 90 and the third member 23 and the shaft supporting means 90 are not rotated, when the second member 22 has a rotation resistance, When one member 21 is rotated once in the rotation direction j1, the second member 22 is rotated about 33/31 in the rotation direction j1 when calculated based on the number of teeth. or,
When the second member 22 is rotated once in the rotation direction j1 when the first member 21 has a rotation resistance, the second member 22 is rotated about 31/33 in the rotation direction j1. The pressing force is absorbed while accompanied by the repulsive force of the pressing force similar to the above, and the direction of the pressing force also becomes substantially the same as the above.

Next, when the first member 21 is fixed to the shaft supporting means 90, and the first member 21 and the shaft supporting means 90 are not rotated, when the second member 22 has a rotation resistance, When the four members 24 are rotated once in the rotation direction j1, the second member 22 is rotated approximately 2/31 in the rotation direction j3 based on the number of teeth. However, in this state, when the rotation of the fourth member 24 is stopped (may be rotated) and the second member 23 is pressed to rotate in the rotation direction j1 or the direction j3,
The direction in which the pressing force acts is not in the direction of the central axis 81, and the external gears g3 and g4 and the rotary shaft 31 are inclined at least with respect to the central axis 81 and the relative angle with respect to the central axis 81. The internal gear g7 fixed to the external gear g3 and the external gear g3 is firmly meshed with the external gear g3 to receive the applied pressure and are relatively restrained (locked). In order to change the tooth surface of the internal gear g7 to the external gear g
3 cannot rotate and the external gear g4 cannot rotate on the tooth surface of the internal gear g8.
On the other hand, the relative rotation of the second member 22 is prevented. Even in this case, the pressing force is absorbed steplessly by the wedge 10 relative to the elastic member 43.

Next, when the second member 22 is fixed to the shaft supporting means 90 and the second member 22 and the shaft supporting means 90 are not rotated, if the first member 21 has a rotation resistance, When the four members 24 are rotated once in the rotation direction j1, the second member 22 is rotated approximately 2/33 in the rotation direction j1 based on the number of teeth. However, in this state, if the rotation of the fourth member 24 is stopped (may be rotated) and the first member 21 is pressed to rotate in the rotation direction j1 or the rotation direction j3, The direction in which the pressure acts is not in the direction of the central axis 81, and the external gears g3 and g4 and the rotary shaft 31 are inclined at least with respect to the central axis 81 and the relative angle with respect to the central axis 81. The external gear g4 and the internal gear g8 fixed to the internal gear g8 are pressed and moved slightly in a combined direction of the holding directions, the meshing is strengthened, the pressing force is received, and the locking is locked.
As a result, the external gear g4 cannot roll and rotate on the tooth surface of the internal gear g8, and the tooth surface of the internal gear g7 does not rotate.
Will not be able to roll and rotate, and the relative rotation of the first member 21 with respect to the second member 22 will be blocked.

Also in this case, the pressing force is absorbed steplessly by the wedge surface relative to the elastic member 43. Further, the configuration of FIG. 14 has various latent functions and configurations, and any of the various functions and configurations can be utilized. Further, in any of the configurations including the first configuration, the directions in which the pressing force is generated when receiving the pressing force of the rotation are the above-described composite directions and are not concentrated on the central axis 81 at least.

Further, although the external gear and the internal gear are used in the thirteenth and fourteenth embodiments, other gears may be used, or a plurality of gears and rotary shafts may be used. Further, it is not limited to the gear and it is also possible to use a rotating body having a smooth arc-shaped surface or a flat surface that can be frictionally driven as a driving means instead of the gear.
