Description

Riding device, power generation device, transport device and exercise device

The present invention relates to a power generation device that converts a predetermined motion of an occupant into a driving force, a riding device that uses the power generation device, and a transport device and an exercise device.

A bicycle is a device configured to convert a force when a passenger steps on a pedal into a driving force, thereby rotating an axle to obtain a propulsive force. A conventional bicycle is generally provided with a frame having a certain shape.

Japanese Patent Laying-Open No. 2015-009671

However, a passenger riding a conventional bicycle must take a posture determined by a fixed frame or pedal position, and in some cases must continue to lean forward, especially in high-speed travel over long distances. The human body may be burdened.

The basic structure of a conventional bicycle is that the left and right pedals are alternately stepped on and the crank and sprocket are rotated to drive the chain to obtain propulsive force. From the viewpoint of reducing the burden on the human body and from the viewpoint of ergonomic rationality, there are limitations and disadvantages derived from the structure.

An object of the present invention is to solve the disadvantages of the prior art described above, and to provide a riding device, a power generation device, and the like that can reduce the burden during traveling and realize high-speed and comfortable long-distance traveling. .

In order to solve such a problem, the present inventor has conceived a completely different configuration from the viewpoint of efficiency of driving force, a viewpoint of reducing a burden during travel, and an ergonomic rationality. I came up with an idea. The riding apparatus according to the present invention is
A frame that expands and contracts according to a predetermined movement of the occupant and changes the axial distance of the front and rear wheels;
A power generation device that converts the extension operation of the frame into the power of the wheels;
It is characterized by providing.

Moreover, the riding apparatus according to the present invention is
Drive wheels,
Non-drive wheels,
A front frame and a rear frame that respectively support either the driving wheel or the non-driving wheel, and are connected to each other so as to be relatively deformable in a manner that changes the axial distance of the driving wheel and the non-driving wheel. When,
A seat provided on the rear frame;
A pedal provided on the front frame;
A winding member provided on a central axis of the drive wheel;
A linear member in which a proximal end is wound around the winding member and a part of the distal end is locked to a frame supporting the non-driving wheel or a member attached to the frame;
An urging member that urges the winding member in a direction of winding the linear member;
An apparatus for intermittently transmitting power between the winding member and the driving wheel, and that is configured to transmit power from the winding member to the driving wheel only when the linear member is pulled out from the winding member. A clutch device for transmitting;
It is characterized by providing.

If the occupant steps out to push the pedal with the lower limbs while sitting on the seat, the front frame is deformed relative to the rear frame, and the axial distance between the driving wheel and the non-driving wheel increases. At this time, along with this deformation operation, the linear member drawn from the winding member rotates the winding member to drive the drive wheels. Further, when the occupant relaxes the lower limb force, the winding member winds up the linear member by the biasing force of the biasing member, and returns the relatively deformed frame to its original shape. At this time, since the clutch device cuts off the power transmission between the winding member and the drive wheel, the operation of the winding member winding the linear member does not affect the propulsive force of the riding device.

Such a riding device uses one of the greatest forces that can be exerted by the human body, which pushes out the pedal with the lower limbs, and transmits power using a linear member to directly transmit the drive wheels. Since the structure is rotated, efficient and effective traveling is realized. That is, in the conventional running, the muscle mainly used by the occupant stops only on the leg. For example, when only the muscle strength of the leg is used for a long time in the long distance running, the performance of the muscle fatigued portion gradually decreases. On the other hand, the riding apparatus according to the present invention has a structure that converts not only the legs but also the muscle strength of the whole body into motive power, and therefore, when the occupant travels at the same speed, there is less accumulation of fatigue in one part, which is advantageous. It is.

It is preferable that the riding apparatus further includes a handle member that is provided so as to be displaceable with respect to the front frame and that is engaged with a part of the front end side of the linear member. In this case, the occupant can further pull out the linear member by performing an operation of displacing the handle, and generate further propulsive force of the riding apparatus.

The handle member preferably includes a rolling handle that can rotate in the pitching direction. Even when the angle of the rolling handle relative to the occupant changes as the handle member is displaced, the rolling handle rotates appropriately to follow the movement of the occupant's palm.

Moreover, it is preferable that the riding apparatus further includes a pulley member around which a part of the linear member is wound to change the direction of the path of the linear member. According to the pulley member, the path of the linear member is set in accordance with the deformation mode of the frame and the displacement mode of the handle, and the frame deformation and the handle displacement can be more efficiently converted into power.

The riding apparatus may further include a pulley position changing mechanism that changes the position of the pulley member. By changing the position of the pulley member and changing the path of the linear member, the drawing amount of the linear member when the frame is deformed or when the handle is displaced can be changed.

It is also preferable that the winding member has a tapered shape. If the linear member is wound from the small diameter portion to the large diameter portion of the tapered winding member, the amount of rotation of the drive wheel increases as the linear member is pulled out. That is, according to this, it is possible to provide a function equivalent to a continuously variable transmission that automatically shifts using the structural features of the machine.

In addition, the riding device may further include a backrest provided behind the seat. The backrest makes it easier for the occupant to take a posture suitable for high-speed and comfortable long-distance travel.

Further, in the riding device, the linear member and the winding member may be provided in pairs on the left and right.

Moreover, the power generation device according to the present invention includes:
An output shaft;
A first frame that supports the output shaft;
A second frame that is deformably connected to the first frame;
A seat provided on the first frame or the second frame;
A pedal provided on the second frame or the first frame;
A winding member provided on the output shaft;
A linear member in which a proximal end is wound around the winding member and a portion of the distal end is locked to the second frame;
An urging member that urges the winding member in a direction of winding the linear member;
An apparatus for intermittently transmitting power between the winding member and the output shaft, wherein power is transferred from the winding member to the drive wheel only when the linear member is pulled out from the winding member. A clutch device for transmitting;
It is characterized by providing.

According to such a power generation device, one of the greatest forces that the human body can exert, such as pushing out the pedal by the lower limbs, can be used as power. Further, since the structure is such that power is transmitted using a linear member and the output shaft is directly rotated, efficient and effective travel is realized.

Such a power generation device can be applied to a power source such as a human-powered propeller aircraft or a power generation device.

In addition, the transport device according to the present invention is
Drive wheels,
Non-drive wheels,
A front frame and a rear frame that respectively support either the driving wheel or the non-driving wheel, and are connected to each other so as to be relatively deformable in a manner that changes the axial distance of the driving wheel and the non-driving wheel. When,
A seat provided on the rear frame;
A pedal provided on the front frame;
A winding member provided on a central axis of the drive wheel;
A linear member in which a proximal end is wound around the winding member and a part of the distal end is locked to a frame supporting the non-driving wheel or a member attached to the frame;
An urging member that urges the winding member in a direction of winding the linear member;
An apparatus for intermittently transmitting power between the winding member and the driving wheel, and that is configured to transmit power from the winding member to the driving wheel only when the linear member is pulled out from the winding member. A clutch device for transmitting;
It is characterized by providing.

Moreover, the exercise device according to the present invention includes:
An output shaft;
A first frame that supports the output shaft;
A second frame that is deformably connected to the first frame;
A seat provided on the first frame or the second frame;
A pedal provided on the second frame or the first frame;
A winding member provided on the output shaft;
A linear member in which a proximal end is wound around the winding member and a portion of the distal end is locked to the second frame;
An urging member that urges the winding member in a direction of winding the linear member;
An apparatus for intermittently transmitting power between the winding member and the output shaft, wherein power is transferred from the winding member to the output shaft only when the linear member is pulled out from the winding member. A clutch device for transmitting;
A load device connected to the output shaft;
It is characterized by providing.

In the embodiment described below, the present invention will be described based on an example in which the present invention is applied to a two-wheeled bicycle (see FIG. 1 and the like).

<Configuration Example of Passenger Device 100>
The riding device 100 shown in FIG. 1 and the like includes a handle member 30, a head tube 5, a top tube 6A, a down tube 6B, a base frame 7, a telescopic adjustment tube 8, a one-way clutch (clutch device) 9, a winding cone (winding). 10), mainspring spring (biasing member) 11, front fork 12, handle 13, arm 15, wire (linear member) 18, wire pulley (pulley member) 19, pedal 20, pulley position changing mechanism 21, seat 72, a backrest 74, and the like (note that FIG. 7 shows the handle 13 rotated 90 degrees together with the head tube 5). The handle member 30 includes a rolling handle 1, a steering rod 2, a front joint rod 3, a rear joint rod 4A, a rear joint link 4B, and the like.

The head tube 5 as the front frame constitutes the front skeleton of the riding apparatus 100, and the base frame 7 as the rear frame constitutes the rear skeleton. The head tube 5 supports a front wheel 55 that is a non-drive wheel via the front fork 12, and the base frame 7 directly supports a rear wheel 75 that is a drive wheel (see FIG. 1 and the like).

The head tube 5 and the base frame 7 are pin-coupled to a top tube 6A that is a link member and a down tube 6B that is also a link member, and together with the top tube 6A and the down tube 6B constitute a four-bar linkage mechanism. (Refer to FIG. 1 etc.). Thereby, the relative position of the head tube 5 and the base frame 7 is changed, and the axial distance of the riding apparatus 100 (also referred to as a wheel base, which is the distance between the center of the front wheel 55 and the center of the rear wheel 75) is changed (see FIG. 1, see FIG. In addition, a bearing may be utilized for the portion to be pin-coupled as necessary (hereinafter the same).

The front ends of the top tube 6A and the down tube 6B are pin-coupled to the plate-like joint portion 5A of the head tube 5, and the respective rear ends are pin-coupled to the base frame 7 (see FIG. 1, FIG. 15, etc.). The top tube 6A and the down tube 6B of the present embodiment are, for example, H-shaped steel formed into an H shape, and the four ends of the H shape (in addition to two locations including one front end and one rear end) Good) has a built-in bearing, and constitutes a four-bar linkage mechanism.

The head tube 5 incorporates a bearing (not shown) and supports the front fork 12. Arms 15 are connected to the left and right sides of the lower portion of the head tube 5 (see FIG. 7). A pedal 20 is attached to the lower portion of the arm 15 via a pedal support member 16. The arm 15 includes an expansion / contraction adjustment tube 8 (see FIG. 7 and the like).

The head tube 5 and the base frame 7 have a rigidity required for running the vehicle body while reducing the weight for steering the vehicle body of the riding device 100. In addition, the head tube 5 and the base frame 7 can be smoothly operated without causing an operation of relative deformation so as to expand and contract without hindering an operation of a traveling passenger.

The seat (stool) 72 is formed on the base frame 7 (see FIG. 1 and the like). A backrest 74 is provided behind the seat 72. The backrest 74 can be used when the occupant takes a posture suitable for high-speed and comfortable long-distance running, for example, a lying posture in an easy state (see FIG. 5 and the like). The shape, size, and material of the seat 72 are not limited as long as the seat 72 can be seated and the backrest 74 can be seated.

The handle member 30 is provided so as to be displaceable so as to function as a steering device as well as a steering device as well as a steering wheel in a conventional bicycle. The handle member 30 of the present embodiment is provided so as to be able to roll to the left and right with respect to the head tube 5, steer the riding device 100 by rolling the handle member 30 to the right (left), and change the traveling direction. It can be changed to the right (left). Although not particularly illustrated, the head tube 5 is provided with a bearing for the handle member 30 as necessary.

Further, the handle member 30 is provided so as to be displaceable with respect to the head tube 5 so that the occupant can pull it up using the upper limbs. Specifically, the handle member 30 includes the steering bar 2, the front joint bar 3, the rear joint bar 4A, the rear joint link 4B, and the like as follows.

First, the steering rod 2 is composed of a pair of left and right two rods (see FIG. 6). A pipe 2A for inserting the rolling handle 1 is provided at the upper ends of these two bars. The steering rod 2 may be composed of a single rod, or the two rods may be joined together. Needless to say, the parts constituting the steering rod 2 and the handle member 30 are not limited to rod-like parts, and may be curved or bent as long as they can function.

The rolling handle 1 constitutes a grip that is held by an occupant. The rolling handle 1 of the present embodiment is supported by a pipe 2A so as to be rotatable in the pitching direction (see FIG. 6 and the like).

The front joint bar 3 is composed of a pair of left and right bars (see FIG. 6). One end portion of the front joint rod 3 is pin-coupled near the lower portion of the steering rod 2 via a connecting shaft 32 and a pin joint (member composed of pins, rivets, bolts, bearings, etc., the same applies hereinafter) 34, and the other end portion. Is pin-coupled to the front fork 12. In addition, the front joint rod 3 may be configured by one of the left and right bars.

The rear joint rod 4A and the rear joint link 4B have two joints, one for each of the left and right of the steering rod 2, for a total of four to form a joint structure (see FIG. 6 and the like). A total of two rear joint rods 4A and rear joint links 4B may be provided on either the left or right side of the steering rod 2. One end of the rear joint rod 4A is pin-coupled via a pin joint 43 around the middle of the steering rod 2, and the other end is pin-coupled via a pin joint 44 to a part of the rear joint link 4B. The other end of the rear joint link 4 </ b> B is pin-coupled to the upper portion of the front fork 12 via a connecting shaft 42 and a pin joint 45.

The connecting shaft 42 is the same as the handle 13 or a portion joined to the handle 13. That is, the handle 13 passes through the inside of the head tube 5 and is connected to the front fork 12, and realizes a steering function with the same structure as a general bicycle. Further, while a general bicycle has a handle connected to the front fork 12 at one location, the handle 13 of the present embodiment is connected to the handle 13 at two locations (the portion where the connecting shaft 42 and the connecting shaft 32 are connected). Therefore, it is possible to perform stability during running and stopping, and to perform steering smoothly.

The winding cone 10 is provided on the center shaft 76 of the rear wheel 75 (see FIG. 8). The winding cone 10 functions as a winding member that winds and stores the wire 18, and is connected between the one-way clutch 9 and the mainspring spring 11 in the power transmission path. One end of a wire 18 is attached to the small diameter portion of the winding cone 10.

In the present embodiment, the power generation devices 200 including the winding cone 10, the wire 18, the wire pulley 19 and the like are symmetrically arranged on the left and right. In this way, the power generation device 200 composed of a pair of left and right members bisects the power and transmits it equally to the left and right. Note that the winding cone 10, the wire 18 and the like can function even when provided on either the left or right side instead of the left and right pair, and in such a case, further weight reduction is possible.

The wire 18 is wound around the taper cone 10 in order from a small diameter portion to a large diameter portion. For this reason, when the wire is pulled out, the amount of rotation of the winding cone 10 and the rear wheel 75 increases as the wire 18 is pulled out, and acceleration occurs. That is, a function equivalent to a continuously variable transmission that automatically shifts is realized by utilizing the characteristics of the structure that employs a tapered member.
That is,
(1) As the rotation decreases from the large diameter portion to the small diameter portion of the winding cone 10, the rotational speed of the drive unit for the same pulling distance increases. This means that if the rolling handle 1 is pulled at the same speed, acceleration is automatically generated, and conversely, even if the pulling force gradually decreases, the speed can be maintained. In terms of ergonomics, the ease of entering force differs depending on when the rolling handle 1 is started to be pulled and when the rolling handle 1 is finished. Therefore, according to this mechanism, adjustment according to the individual can be performed.
(2) As the angle from the small diameter portion to the large diameter portion of the winding cone 10 increases, the wire 18 may slip or clog toward the small diameter portion. However, slipping can be prevented by providing fine grooves and steps on the surface of the cone.
(3) Even when a cylindrical body is employed instead of the winding cone 10, acceleration can be generated like a cone. That is, for example, the wire 18 is tapered so that the diameter gradually changes so that the wire 18 itself has a width and thickness, and the other part of the wire 18 is wound on the wound wire 18 so as to be folded. Thus, there is a difference in circumference between the portion folded inward and the portion folded outward. It is possible to generate acceleration using the difference between the circumferences.
(4) Although not specifically shown, by providing a step in the winding cone 10 and changing the step in which the wire 18 is wound, the performance equivalent to the speed change function adopted in a general bicycle is obtained. It can also be demonstrated.

In addition, although the conical body is used as the winding member here, a winding member having a shape in which the bus bar is not a straight line but has a bulge or a constriction (for example, a spindle shape) may be employed. Further, as the winding member, a member having a constant diameter such as a cylindrical shape can be used instead of a tapered member such as the winding cone 10. In the present embodiment, the winding cone 10 is rotated coaxially with the central axis 76, but this is only a preferred example, and the winding member is not coaxial with the central axis 76. And may be connected by a gear train.

The mainspring 11 urges the winding cone 10 in the direction in which the wire 18 is wound. If the wire 18 is pulled out, the mainspring spring 11 is wound as it is pulled out, and the repulsive force due to elasticity is stored. Although not shown in particular, the mainspring 11 is housed in the casing, one end (for example, the inner end) of the mainspring 11 is connected to the central shaft 76, and the other end is fixed inside the casing. When the cone 10 rotates forward, the cone 10 is wound in the casing from one end (inner end) side and is fed. Further, when the force for pulling the wire 18 (that is, the torque for rotating the winding cone 10) does not work, the winding cone 10 is rotated in the reverse direction by the repulsive force that has been fed.

The mainspring spring 11 described in the present embodiment is only a suitable example of a member that biases the winding cone 10. In addition, an elastic member that generates a required torque, such as a spring wheel or a coil spring, can be used as the urging member.

The one-way clutch 9 is a device that interrupts power transmission between the winding cone 10 and the rear wheel 75. The one-way clutch 9 of the present embodiment is configured to transmit power from the winding cone 10 to the rear wheel 75 to rotate forward only when the wire 18 is pulled out from the winding cone 10. Yes.

<About the one-way clutch 9>
Here, the one-way clutch 9 in the riding apparatus 100 of the present embodiment will be described in detail (see FIG. 9 and the like). That is, the one-way clutch (clutch device) 9 is
An inner ring body (drive side rotating body) 91 that rotates by receiving a driving force;
A plurality of recesses 92 formed on the outer peripheral surface 91A of the inner ring body (drive side rotating body) 91;
A power transmission roller (power transmission body) 93 disposed corresponding to the recess 92;
An inertia claw (tubular shape) having a chamber 94C partitioned by a restriction wall 94B for restricting the movable range in the circumferential direction of the power transmission roller 93 and capable of rotating relative to the inner ring body (drive side rotating body) 91. Intermediate rotating body) 94,
An outer ring body (driven-side rotating body) 95 having a transmitted surface 95D with which the power transmission roller 93 contacts and separates;
With
The recess 92 is
An extruding portion 92P that pushes the power transmission roller 93 radially outward when the inner ring body 91 rotates in the forward direction and contacts the transmitted surface 95D of the outer ring body 95;
A claw portion 92Q that cooperates with the restriction wall 94B and maintains the power transmission roller 93 at a position not in contact with the transmitted surface 95D of the outer ring body 95 except when the inner ring body 91 rotates in the forward direction. ,
It has.

The inner ring body (drive side rotating body) 91 is formed integrally with the winding cone 10 and rotates the same amount as these. The inner ring body 91 of the present embodiment is formed in a ring shape and is fitted to the central shaft 76 in a rotatable state (see FIGS. 12 and 13). Reference numerals 9A, 9B, 9C are bearings provided inside the one-way clutch 9 (see FIG. 8).

For example, three recesses 92 are formed on the outer peripheral surface 91A of the inner ring body 91 at regular intervals (the intervals may be random) as an example (see FIGS. 9 and 14). The recess 92 has an asymmetric shape with different shapes and depths on one side and the other side in the circumferential direction. That is, one side is an extruding portion 92P made of a shallow inclined surface that gently inclines from the outer peripheral surface 91A, and the other side is a claw portion 92Q made of a dent deeper than the extruding portion 92P. The extruding part 92P is so shallow that it cannot maintain the power transmission roller 93 between the extruding part 92P and the regulating wall 94B (see FIG. 11). On the other hand, the claw portion 92Q has an inclined surface that is deep and steep so that the power transmission roller 93 can be hooked and maintained between the claw portion 92Q and the restriction wall 94B (see FIG. 10).

The power transmission roller 93 is a power transmission body that is mounted so as to be movable between a position where the power of the inner ring body 91 is transmitted to the outer ring body 95 and a position where it is not transmitted. The power transmission roller 93 of this embodiment is formed of a cylindrical body, and is provided so as to be able to move inside a chamber 94C formed in the inertia claw 94 (see FIG. 14 and the like). That is, the power transmission roller 93 can move between a position where it abuts against one regulating wall 94B of the chamber 94C and a position where it abuts against the other regulating wall 94B in the circumferential direction, and the inner ring body in the radial direction. It can move between a position where it contacts the recess 92 formed in 91 and a position where it contacts the transmitted surface 95D of the outer ring body 95 (see FIGS. 10 and 11). In place of the power transmission roller 93, for example, a spherical member or the like can be used as the power transmission member.

The inertia claw 94 is a cylindrical member that has a larger inertia than the inner ring body 91 and operates after the movement of the inner ring body 91, for example, by being formed of a material having a higher specific gravity than the inner ring body 91. 91 and the outer ring body 95 (see FIG. 9 and the like). The inertia claw 94 has chambers 94 </ b> C corresponding to the recesses 92 at three locations that are equally spaced in the circumferential direction.

The chamber 94C is composed of a space partitioned by a restriction wall 94B. The restriction wall 94B may be a surface perpendicular to the rotation direction, or may be a surface that is somewhat inclined. Further, the regulation wall 94B may be a smooth surface or a surface including a curved surface or a chamfered surface.

The outer ring body 95 is a member located outside the inertia claw 94. The inner peripheral surface of the outer ring body 95 is a transmitted surface 95D. The outer ring body 95 is connected to the rear wheel 75 and rotates integrally with the rear wheel 75.

Subsequently, the operation of the one-way clutch 9 will be described (see FIG. 10, FIG. 11, etc.).

In the stationary one-way clutch 9, all of the recess 92, the power transmission roller 93, the inertia claw 94 (the regulating wall 94B), and the outer ring body 95 (the transmitted surface 95D) are independent without interfering with each other. It has become.

When the inner ring body 91 is driven to rotate forward, the power transmission roller 93 moves relatively toward the pushing portion 92P of the concave portion 92, and by the outward force received from the inclined surface of the pushing portion 92P, In some cases, the centrifugal force acting on the roller itself is applied and pushed outward to be pressed against the transmitted surface 95D of the outer ring body 95 (see FIG. 11). Further, the inertia claw 94 having inertia applies a force in a direction opposite to the forward direction to the power transmission roller 93 via the regulation wall 94B. Due to the wedge effect by these actions, the inner ring body 91, the power transmission roller 93 and the outer ring body 95 are engaged with each other, and the rotational power of the inner ring body 91 is transmitted to the outer ring body 95. In addition, the inertia claw 94 is braked only when engaged.

When the inner ring body 91 stops or begins to rotate in the opposite direction, the wedge effect is lost, and the meshed state of the inner ring body 91, the power transmission roller 93 and the outer ring body 95 is released. Further, when the inner ring body 91 starts to rotate in the reverse direction, the power transmission roller 93 does not interlock with the movement of the inner ring body 91 due to its own inertia, and the remaining inertia claw 94 causes the power transmission roller 93 to It is pushed out relatively toward the claw portion 92Q. At this time, the claw portion 92Q of the recess 92 sandwiches the power transmission roller 93 between the restriction wall 94B of the inertia claw 94 and maintains the power transmission roller 93 in a state where it does not contact the transmitted surface 95D of the outer ring body 95. (See FIG. 10). Therefore, the rotational power of the inner ring body 91 is not transmitted to the outer ring body 95.

It should be noted that the conventional general one-way clutch is as follows.

That is, as a general one-way clutch, there is a cam-type one-way clutch composed of an outer ring and an inner ring, a roller, a spring, etc., and a pocket having a cam surface provided on the inner side of the outer ring or the outer side of the inner ring (also called a roller type). be called). A roller is disposed inside the pocket and is kept in contact with the cam surface of the outer ring and the outer side of the inner ring or the cam surface of the inner ring and the inner side of the outer ring by a spring. When the outer ring tries to rotate in one direction with respect to the inner ring, the contact surface pressure between the cam surface and the roller increases, and the resistance is transmitted to the inner ring. When rotating in the opposite direction, the contact surface pressure between the cam surface and the roller decreases, and the power transmission is cut off by sliding.

However, such a one-way clutch may cause friction even when the power is cut off. That is, for example, a one-way clutch used for a general bicycle is idling while the clutch can be always engaged while the bicycle is running, and energy is lost due to friction.

On the other hand, the one-way clutch 9 as in the present embodiment activates both the state in which the clutch is engaged and the state in which the clutch is not engaged while the riding apparatus 100 is running, thereby reducing or eliminating the friction when the clutch is not engaged. ing.

<Other configuration of the riding apparatus 100>
The wire 18 is pulled out of the winding cone 10 with the relative deformation operation of the head tube 5 and the like with respect to the base frame 7 and the expansion and contraction operation of the rolling handle 1 and the like with respect to the head tube 5 to rotate the rear wheel 75. . The proximal end side of the wire 18 is attached to the small-diameter portion of the winding cone 10, and the distal end side (the distal end or the middle portion of the wire 18) is attached to the steering rod 2. Moreover, the wire 18 is hung on the wire pulley 19 in the middle (refer FIG. 5 etc.). From the wire pulley 19 to the steering rod 2, the wire 18 is inserted through the head tube 5. Needless to say, the wire 18 functions even if it does not pass through the head tube 5.

The wire pulley 19 is attached to the lower end of the telescopic adjustment tube 8 built in the arm 15 and changes the path of the wire 18 that is hung.

The expansion / contraction adjustment tube 8 is slidable with respect to the arm 15 and constitutes a pulley position changing mechanism 21 that changes the position of the wire pulley 19 (see FIG. 7 and the like). Although not shown in detail in detail, the pulley position changing mechanism 21 includes a member such as a long groove, a butterfly screw or a butterfly bolt for sliding the telescopic adjustment tube 8 and fixing it to the arm 15 at a desired position. By changing the position of the wire pulley 19, it is possible to change the drawing amount of the wire 18 accompanying the frame deformation operation and the handle expansion / contraction operation.

<Operation of the riding apparatus 100>
Subsequently, the operation of the above-described riding apparatus 100 will be described (see FIG. 1 and the like).

When the occupant sits on the seat 72 (see FIG. 1) and steps on the pedal 20 with both feet, the links of the top tube 6A, the down tube 6B, and the head tube 5 move with respect to the base frame 7, and the front wheel 55 The distance between the rear wheels 75, that is, the axial distance (wheel base) increases (see FIGS. 2 and 3). This movement is converted into power for pulling the wire 18 from the winding cone 10 and rotating the inner ring body 91 forward. At this time, since the one-way clutch 9 is in a state of transmitting power as described above, the power is transmitted to the rear wheel 75 and acts as a force for propelling the riding device 100 forward.

Subsequently, when the occupant pulls the rolling handle 1 upward, the links of the front joint rod 3, the rear joint rod 4A, and the rear joint link 4B move, and the rolling handle 1 and the steering rod 2 are pulled up (FIG. 4). reference). Along with this movement, the wire 18 is further pulled out from the winding cone 10 and becomes a power for further rotating the inner ring body 91, and acts as a force for further propelling the riding apparatus 100 (see FIG. 5).

Note that during the operation of pulling the rolling handle 1, the rolling handle 1 automatically rotates in the pitching direction with respect to the steering rod 2 and follows the direction of the occupant's palm. For this reason, it is not necessary for the occupant to hold the rolling handle 1 again, and the lifting operation can be performed smoothly.

Further, as the wire 18 is pulled out from the winding cone 10, the mainspring spring 11 is wound, and the winding cone 10 is biased in the direction in which the wire 18 is wound. When the occupant relaxes the force of both feet that have been stepped on and the force of the arm that has been pulled up, the winding cone 10 rotates in the reverse direction and winds up the wire 18, and accordingly, the top tube 6A, down tube 6B, head Each link of the tube 5, each link of the front joint rod 3, the rear joint rod 4A, the rear joint link 4B, the rolling handle 1, the steering rod 2, etc. return to the initial state (see FIG. 1). At this time, since the one-way clutch 9 is in a disengaged state, the rear wheel 75 continues to rotate in the forward direction and does not affect the running of the riding apparatus 100.

Heretofore, as an example of the form of returning to the initial state, the wire 18 is rewound by the force of the mainspring spring 11, whereby the front wheel 55 is pulled back, and the head tube (front frame) 5 and the base frame (rear frame) 7. However, the mechanism for returning these frames to the initial state is not limited to this, and there are other forms as described below.

(1) By using a stretchable linear member (such as a rubber string) instead of the heel wire 18, the effect of pulling back the front wheel 55 and the effect of returning the frame to the initial state can be enhanced. .

(2) There is friction between the foot (shoe) that pushes the heel pedal 20 and the pedal 20. This friction is also used when the foot is pulled back, and the frame expansion and contraction is returned to the initial state in conjunction with the pulling motion. Note that the shoe can be joined or fixed to the pedal 20 by binding as in a general sports road bike.

(3) When the rear wheel 75 is used as a driving wheel, the front wheel 55 is more affected by friction from the ground than the rear wheel 75, so that the speed of the front wheel 55 is delayed, resulting in friction. The resistance force acts as a force to return the frame to the initial state.

(4) The air resistance acting on the front wheel 55 that directly receives air from the eaves traveling direction is greater than the air resistance acting on the rear wheel 75 located behind the front wheel 55. For this reason, the air resistance acting on the front wheel 55 helps the force to return the frame to the initial state.

(5) A stopper 51 installed between the top tube 6A connected to the head tube 5 and the front end of the down tube 6B on the head tube 5 side restricts the movable range of the top tube 6A relative to the head tube 5, and the frame The movement is restricted so that the (vehicle body) does not become too stretched (see FIG. 15). Further, the stopper 51 restricts the movement of the down tube 6B when the frame (vehicle body) returns to the initial state, and restricts the contraction of the down tube 6B.

(6) Centering on the drive part (winding cone 10) of the rear wheel 75, two points, a connection point 6a between the base frame 7 and the top tube 6A, and a connection point 6b between the base frame 7 and the down tube 6B. The center of gravity of the occupant (in FIG. 20, a symbol representing the center of gravity is attached) is located on the circumference represented by the alternate long and short dash line (see FIG. 20). Moreover, the line shown with the broken line and the dashed-two dotted line represents the force added from said 2 connection location 6a, 6b and a passenger | crew's gravity center. These are vector lines, the direction, and the length and number of the lines indicate the strength of the force. When the weight of the occupant rotates counterclockwise in FIG. 20, the top tube 6A is pushed forward relatively. When the head tube 5 receives a strong force from the top tube 6A, the top tube 6A moves up and the front wheel 55 moves backward. The above is the mechanism in which the frame returns to the initial state due to the influence of the weight of the occupant. However, the force indicated by the broken line and the two-dot chain line changes by changing the position where the occupant sits, which affects the ease of return.

Here, in order to make it easier to understand the movement of each member, the operation of depressing the pedal 20 and the operation of pulling up the rolling handle 1 have been described separately. However, the greatest power can be obtained by using the pedal 20. This is when the stepping-out operation and the operation of pulling up the rolling handle 1 are performed simultaneously. This motion is similar to the motion of lifting the barbell at a stretch by weight lifting, and the strongest force can be generated when the motion of pulling and pressing the motion at the same time are performed simultaneously.

Further, as can be seen from the contents shown in FIGS. 4, 5, etc., the rolling handle 1 does not move linearly at the time of pulling, but each link of the front joint bar 3, the rear joint bar 4A, and the rear joint link 4B. It moves on the curve determined by. For this reason, the occupant can pull up the rolling handle 1 in such a manner as to draw a parabola as when rowing a boat.

Moreover, as can be seen from the figure, the occupant can continue to ride on the riding apparatus 100 while keeping the weight on the backrest 74. Therefore, it is easy to take a posture suitable for high-speed and comfortable long-distance driving, and it is hard to get tired.

In the riding apparatus 100, when the vehicle travels, the situation where the wire 18 is rewound (the situation where the one-way clutch 9 is not engaged) is always after the situation where the wire 18 is pulled out (the situation where the one-way clutch 9 is engaged). appear. In this respect, the riding apparatus 100 of the present embodiment is completely different from a general bicycle or the like. That is, if resistance is generated in a situation where the wire 18 is rewound, unnecessary resistance may be given to the traveling itself, but such resistance is eliminated in the riding apparatus 100.

According to such a riding apparatus 100, the human body (occupant) can fully exert its power, and at the same time, the speed can be reduced by reducing the air resistance, and the constitution can be improved by the whole body movement based on ergonomics. And can achieve a fitness effect.

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the present invention has been described with reference to an example in which the present invention is applied to a bicycle. However, a similar structure has more than two wheels (including auxiliary wheels) such as a three-wheeled vehicle and a four-wheeled vehicle. Needless to say, the present invention can also be applied to a passenger apparatus having the following (see FIG. 17).

Further, in the above-described embodiment, as the frame that expands and contracts according to the predetermined movement of the occupant and changes the axial distance of the front and rear wheels, it is as if the links of the top tube 6A, the down tube 6B, and the head tube 5 are used. Although a frame that bends and stretches like a scale insect has been illustrated, this is only a preferred example. Although not shown in particular, the front frame and the rear frame slide linearly using a linear motion slider (for example, one in which large and small pipes are fitted and slid to displace one). A frame that can be expanded and contracted by a mechanism that performs the above operation can also be configured.

Further, in the above-described embodiment, the riding device 100 having a structure that converts both the operation of depressing the pedal 20 and the operation of pulling up the rolling handle 1 into power is illustrated, but this is only a preferable example. Although not particularly illustrated, by attaching the tip end side of the wire 18 not to the steering rod 2 but to the head tube (front frame) 5, only the operation of depressing the pedal 20 can be converted into power. In this case, the rolling handle 1 functions as a steering device that is not related to the propulsion power of the riding device 100. A steering device other than the rolling handle 1 may be employed (for example, a front wheel device that turns the rudder in response to weight shift in a three-wheeled vehicle).

In the above-described embodiment, the riding apparatus 100 that drives the rear wheel 75 is illustrated, but this is also only a suitable example. Although not specifically shown, the present invention can be applied to the riding apparatus 100 having a structure for driving the front wheels 55 on the contrary. In such a front wheel drive riding apparatus 100, the rear wheel 75 may be a steering wheel.

Further, the power generation device 200 described in the above-described embodiment can be applied not only to bicycles and the like, but also to various devices such as human power propeller aircraft and human power generators. The power generation device 200 includes an output shaft 78 instead of a rear wheel (drive wheel) (see FIG. 18), a base frame (first frame) 7 that supports the output shaft 78, and the base frame 7. A head tube (second frame) 5, a seat 72, a pedal 20, and a winding cone (winding member) 10 provided on the output shaft 78. The base end side is wound around the winding cone 10, and a part of the distal end side is locked to the head tube 5 (a linear member) 18, and the wire 18 is wound in the winding direction. Power transmission between the mainspring spring (biasing member) 11 that biases the cone 10 and the winding cone 10 and the output shaft 78 is interrupted, and the wire 18 is pulled out from the winding cone 10. From the winding cone 10 only when Provided to the power shaft 78 and the one-way clutch 9 for transmitting power, the.

In this case, for example, in the power generation device 200, the base frame 7 is supported by the pedestal 202, while the head tube 5 is supported by the slider 204 on the pedestal 202 so as to be slidable in the front-rear direction (see FIG. 16). ). Thereby, the output shaft 78 can be rotated while the frame 202 is expanded and contracted on the pedestal 202. The output shaft 78 rotates the propeller 206 connected directly or indirectly (see FIG. 18). Reference numerals 208 and 210 are bearings.

Further, the power generation device 200 used in the human power generator 400 rotates the rotation shaft of the human power generator 400 with the output shaft 78 (see FIG. 19). An inertia wheel 402 may be provided on the output shaft 78.

According to the power generation device 200 as described above, one of the greatest forces that the human body can exert, such as pushing out a frame or the like by the lower limbs, can be used for power. Furthermore, an output by pulling the handle with the upper limb can be added. In addition, since the power is transmitted using the wire 18 and the output shaft is directly rotated, power can be generated efficiently and effectively.

In other words, the muscles mainly used by the occupant in the conventional running stop only in the leg, for example, when only the muscle strength of the leg is used for a long time in long distance running, the performance of the muscle fatigued part gradually decreases, On the other hand, according to the riding device 100 of the present embodiment that converts not only the legs but also the muscle strength of the whole body into power, there is less local fatigue accumulation in one part of the occupant when traveling at the same speed, This is advantageous.

The present invention is suitable for application to a vehicle such as a bicycle having a plurality of wheels and propelled by human power. The present invention is also suitable for application to power sources such as human-powered propeller aircraft and power generators.
