Description

Description: FIELD OF THE INVENTION The present invention relates to an apparatus for obtaining an inclined surface by artificially tilting and moving a plane, and in particular, to any movable device whose inclination direction is not restricted. The present invention relates to a device for obtaining an inclined surface.

2. Description of the Related Art A sports training apparatus, a special environment simulation apparatus, and the like using a limited relatively small surface artificially inclined and using the inclined surface are used. Especially in recent years,
With increasing interest in health, training has been conducted from a scientific or sports medical standpoint, and more complicated slopes and arbitrary slopes whose slope directions are not limited can be easily obtained. Devices that are required.

[Problem to be Solved by the Invention] As a device used for the above-mentioned purpose, in the past, most of devices in which the inclination was limited to a specific direction,
There was an expensive simulation device that created a special environment with a partly wide range of functions. All of them are functionally restricted and have low versatility, so multiple units must be installed to obtain complex functions, or a large-scale system requires extremely expensive and extensive installation space. For example, it has been used only for limited applications.

Therefore, in the present invention, it is intended to enable more effective training by obtaining an arbitrary inclined surface which is not functionally restricted and a mechanism for horizontally moving the inclined surface with an inexpensive device.

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration. That is, a member constituting a first surface rotatably supported about one rotation axis, and a fulcrum of the rotation axis of the first surface included in the surface and orthogonal to the rotation axis of the first surface. A gimbal mechanism comprising a member constituting a second surface rotatably supported about a rotating shaft to be rotated, and a fixed member supporting the rotating shaft of the second surface; A frame member movably supported on the frame member, driving means for horizontally moving a fixed member with respect to the frame member, one end of which is locked to a member constituting a first surface of the gimbal mechanism, and the other end is Consists of a pair of telescoping means locked to the fixing member,
The position where the expansion / contraction means is locked to the first surface is disposed in each of adjacent regions divided by two orthogonal rotation axes of the gimbal mechanism, and the member constituting the first surface is fixed to the fixed member. Both ends locked by the member are locked so as to be tiltable with respect to the locking surface with respect to the locking point.

[Operation] In the device configured as described above, when the load surface of the gimbal mechanism is held horizontally, the expansion / contraction means is held at an intermediate position between expansion and contraction. This state is referred to as an initial state. The inclination of the load surface of the gimbal mechanism can be obtained by appropriately and selectively driving the pair of expansion and contraction means from the initial state.

First, by extending and contracting both the expansion and contraction means simultaneously, the area where the expansion and contraction means is locked when the expansion and contraction means is extended around the center line between the area where the expansion and contraction means is locked and the other area as the center of rotation. Rise, and the other areas fall, so that the inclination of the load surface can be obtained. Conversely, when the expanding / contracting means is contracted, the ascending and descending of each area is reversed, and the inclination of the load surface opposite to the above can be obtained.

When the expansion and contraction of the expansion and contraction means are made to be opposite to each other, the area where the extended expansion and contraction means is locked and the area where the expansion and contraction means adjacent to the area is not locked rises, and the contracted expansion and contraction means The locked area and the area where the expansion and contraction means adjacent to the area are not locked are lowered to obtain the inclination of the load surface. When the expansion and contraction of the expansion and contraction means are reversed, a reverse inclination of the load surface can be obtained.

When one of the pair of expansion and contraction means is driven to expand and contract and the other is fixed at an intermediate position between the extension and the contraction, the area where the one expansion and contraction means is locked by the one expansion and contraction is raised or lowered. Indicates that a region at a diagonal position falls or rises.

Next, as for the horizontal movement, when the fixed member is reciprocated along the frame member by the driving means integrally with the gimbal mechanism, the fixed member operates in combination with the tilting operation of the gimbal mechanism or independently. That can be done.

[Example] Hereinafter, a more detailed description will be given based on the illustrated example.

In the figure, 1 is a member constituting the first surface or the first surface, 2 is a member constituting the second surface or the second surface, 3
Is a fixing member, 4 is a rotation axis of the first surface, 5 is a rotation axis of the second surface, 6 and 7 are expansion and contraction means, and 8 is an expansion and contraction means 6 and 7 related to the first surface 1 and the fixing member 3. It is a universal mechanism that stops. 101 is a first frame member, 102 is second frame members 103 and 104 are driving means.

FIG. 1 is a diagram schematically showing the present invention, and FIG. 2 is a vertical sectional side view of FIG. FIG. 3 is a longitudinal sectional side view showing an example of the expansion / contraction means 6, 7, and FIG. 4 is an exploded perspective view showing a universal mechanism for locking the expansion / contraction means 6, 7 to the first surface 1 and the fixing member 3. .

Now, for a specific explanation, an explanation will be given based on an apparatus composed of a combination of FIG. 1, FIG. 2, FIG. 3, and FIG. In the figure, the first surface 1 is in an initial state.
And the second surface 2 is held in a horizontal state. That is, the prime mover 18, which is preferably constituted by a servomotor, is driven so that the detecting piece 22 of FIG. 3 is engaged with the detector 26, and the telescopic means 6, 7 are held at the intermediate position. In order to obtain an inclined surface, the expansion and contraction means 6 and 7 may be selectively expanded and contracted. First, in order for the areas A and B to move up and down at the same time about the rotation axis 5, and to make the areas C and D move up and down at the same time,
The expansion and contraction means 6 and 7 are simultaneously extended and contracted. Each prime mover 18 connected to the expansion and contraction means 6 and 7 is simultaneously driven.
When the nut 12 fixed to the rotating cylinder 13 is rotated by the driving of the prime mover 18 via the belt wheel 17, the belt 16, and the belt wheel 15, the screw shaft 11 moves up or down according to the rotation direction of the nut 12. When the screw shaft 11 rises, the areas A and B rise and the areas C and D fall together with the second surface 2 and the first surface integrated around the rotation shaft 5. Similarly, when the screw shaft 11 descends, the areas A and B descend and the areas C and D rise as the second surface 2 and the first surface 1 are integrated around the rotation shaft 5. Next, when one of the screw shafts 11 of the expansion / contraction means 6 and 7 is raised and the other screw shaft 11 'is lowered, the first surface 1 forms a second surface around the rotation shaft 4. The tilting movement is performed in the member 2, and the screw shaft 11 of the expansion / contraction means 6 rises,
When the screw shaft 11 'is lowered, the areas A and D rise around the rotation shaft 4, and the areas B and C fall. Further, when one of the expansion and contraction means 6 and 7 is held at the neutral position and the other performs the expansion and contraction operation, the area where the expansion and contraction means performing the expansion and contraction operation is locked and the area at the diagonal position thereof rises, Perform a descending operation. For example, when the expansion / contraction unit 6 performs the expansion / contraction operation and the expansion / contraction unit 7 is held at the neutral position, the area A and the area C move up and down. Strictly speaking, a line connecting the intersection point P of the axis Y of the rotating shaft 4 and the axis X of the rotating shaft 5 and the point at which the stretching means 7 is locked to the first surface 1 by the stretching movement of the stretching means 6. The first surface 1 and the second surface 2 can move together to move the region A and the region C up and down around W. At this time, the region B and the region D rotate around the line W. That is, as a whole, the region A side and the region C side move up and down around the axis W with the line W as a fixed axis. Similarly, when the expansion and contraction means 7 performs the expansion and contraction operation and the expansion and contraction means 6 is stopped, the area B side and the area D side move up and down about the line V. Surface 1 of expansion / contraction means 6, 7
Are locked with the axes Y and X of the rotating shafts 4 and 5, respectively.
Are arranged on the lines V and W that bisect the angle between the orthogonal axes X and Y in the areas A and B defined by By being held at the position, it is possible to effectively perform a tilting operation about the axis V or W, and to expand and contract in a movement about any of the axes X and Y. Control is easy because the amount of expansion and contraction of the means and the amount of inclination of the surface correspond one-to-one.

In any operation, the rotation axes 4, 5 and the line V,
Coupled with the fact that both W are arranged on the same plane of the first surface 1, the point P is not moved as a fixed point at all times.

Assuming that the expansion / contraction means 6 and 7 are installed perpendicularly to the first surface 1 and the fixing member 3 in the neutral position, if the member 1 constituting the first surface is extended or contracted and the member Although the vertical state cannot be maintained with respect to the first surface 1 and also with respect to the fixing member 3, both ends of the expansion and contraction means 6 and 7 are locked by the universal mechanism, so that the inclination of the surface 1 may be reduced. It can also follow effectively. Although the expansion and contraction means 6 and 7 are inclined with respect to the fixed member 3 by the inclination of the surface 1, the inclination angle is minute, and if the expansion and contraction means 6 and 7 are driven by the motor 18 via the belt 16, The belt 16 effectively absorbs the slight inclination between the expansion / contraction means 6 and 7 and the fixing member 3 and can operate satisfactorily.

In the above description, the operation based on the rotation axes 4, 5, the axis V, and the axis W has been described. However, by appropriately controlling the amount of expansion and contraction of the expansion and contraction means 6 and 7, the inclined surface in any direction in which the operation is combined And the elastic means 6,
By controlling the rotation direction and rotation speed of the prime movers 18 and 18 'connected to each of 7, the inclination speed and the inclination angle of the surface 1 can be arbitrarily set.

An embodiment of the universal mechanism 8 is shown in FIG. Needless to say again, a rotating shaft 30 perpendicular to the axis of the expanding and contracting means 6 and 7 is fixed to the extending portion 28 and 29 of the screw shaft 11 or the cylindrical member 14 constituting the expanding and contracting means. A rotation member 32 extending perpendicularly to both the axis of the expansion and contraction means 6 and 7 and the rotation shaft 30 is extended from a support member 31 for supporting the rotation member 30, and the rotation shaft 32 is formed by a locking member 33 to constitute a first surface. 1 and the fixing member 3.

The horizontal movement mechanism will be described. The gimbal mechanism and its driving means are mounted on the fixing member 3 as described above. When the fixing member 3 moves, the gimbal mechanism and the driving means 103 move together with the fixing member 3. ing. Now, the fixing member 3 can be moved in a predetermined direction so that the frame member 10 is movable.
Supported by one. Driving means 103 is provided on the frame member 101. The driving means 103 is preferably constituted by a prime mover 110 such as an electric motor.
2 are extended. On the other hand, the fixing member 3 has the screw shaft 1
A nut 113 that engages with 12 is fixedly provided. A guide rod 116 supported by a support member 114 and a guide rod 119 supported by a support member 117 are disposed on the first frame member 101, and the fixed member 3 is slidable on the guide rods 116, 119, respectively. Sliding members 115 and 118 are provided. Therefore,
By operating the prime mover 110, the screw shaft 112 rotates, and the nut 113 engaged with the screw shaft 112 moves in a predetermined direction depending on the rotation direction of the screw shaft 112, and moves the fixing member 3 to the right or left direction in the second illustration. It is something to move. Since the moving operation of the fixing member 3 can operate independently of the tilting operation of the gimbal mechanism, the moving operation of the fixing member 3 can be performed independently of the gimbal mechanism alone or in cooperation with the tilting operation of the gimbal mechanism. More effective operation can be performed.

If the frame members are arranged in two layers of the first frame member 101 and the second frame member 102, each frame member is configured to be able to move in a direction orthogonal to each other, and if each is driven independently, The desired motion can be obtained by operating the two frame members 101 and 102 and the tilting motion of the gimbal mechanism together or independently, to obtain a more complicated surface motion, more precisely, the first motion. With respect to the load surface embodied on the surface 1, the tilt and horizontal movement operations can be performed alone or in combination.
