  In the above-described conventional exercise equipment, a weight, a fluid cylinder, and the like for generating a load are required. For this reason, the weight of the exercise equipment becomes heavy, and the installation place of the exercise equipment is restricted, and the carrying thereof is inconvenient.

  In addition, when the exercise equipment is used for the purpose of rehabilitation such as an elderly person or a physically handicapped person, for example, the user is in a state of standing by himself / herself. When such training is assumed, the exercise equipment is not required to have a performance that gives a large load to the exerciser, and it is desired that a relatively light load can be easily given to the exerciser. In the exercise equipment using the link structure as in Patent Literature 2, it is considered difficult to use the exercise equipment with a light load. In addition, assuming a light load exercise, it is not advantageous in terms of cost and the like to employ a large structure as in Patent Document 1 because an unnecessary weight is unnecessary.

  In view of the above points, an object of the present invention is to provide an exercise device suitable as a rehabilitation application for a person with reduced motor function. Another object of the present invention is to provide an exercise device that is light in weight and convenient for carrying and installation.

  In order to achieve the above object, an exercise device of the present invention includes a base part placed on a floor surface, a rail part attached to the base part so that an inclination angle with respect to the floor surface can be adjusted, and the rail A chair part supported movably on the part, and a foot pressing part that is fixed to the base part during exercise and is pressed by an athlete sitting on the chair part with a foot (first 1 configuration).

  According to this structure, the load given to an exerciser can be adjusted by adjusting the inclination angle with respect to the floor surface of a rail part. If the inclination angle of the rail portion is set to a small angle, the load applied to the athlete can be considerably reduced. Further, by gradually increasing the inclination angle of the rail portion, the load applied to the exerciser gradually approaches the force required to stand up from the sitting posture. For this reason, the exercise apparatus of this configuration can be suitably used for rehabilitation such as a person who does not stand by himself or herself. Further, the exercise device of this configuration does not require a weight or a hydraulic tool for applying a load to the exerciser. For this reason, the exercise apparatus of this configuration has a high degree of freedom in carrying and installation.

  In the exercise apparatus having the first configuration, a configuration (second configuration) in which a surface of the foot pressing portion that is pressed by an athlete can adjust an inclination angle with respect to the floor surface is preferable. According to this structure, it is easy to make an exerciser exercise safely with an appropriate posture.

  In the exercise device having the second configuration, the foot pressing portion is attached to one end side of the rail portion, and a surface of the foot pressing portion that is pressed by an athlete is used to change an inclination angle of the rail portion. A configuration (third configuration) in which the tilt angle is changed in conjunction with it is preferable. This configuration is convenient because the adjustment of the inclination of the rail portion and the adjustment of the inclination of the foot pressing portion can be performed together.

  In the exercise apparatus having any one of the first to third configurations, it is preferable that the rail portion has a configuration (fourth configuration) in which an inclination angle with respect to the floor surface can be changed steplessly. According to this configuration, it is easy to set an appropriate exercise load in accordance with the muscular strength level of the exerciser.

  In the exercise apparatus having any one of the first to fourth configurations, the chair portion includes a seat portion on which an exerciser places a buttock, and a backrest portion on which an exerciser sitting on the seat portion can lean, It is preferable that the backrest has a configuration (fifth configuration) in which an inclination angle can be changed with respect to the seat. According to this configuration, it is possible to exercise the exerciser safely in an appropriate posture in accordance with the inclination angle of the rail portion with respect to the floor surface.

  ADVANTAGE OF THE INVENTION According to this invention, the instrument for exercise suitable as a rehabilitation use of the person with a reduced motor function can be provided. Further, according to the present invention, it is possible to provide an exercise device that is light in weight and convenient for carrying and installation.

<Configuration of exercise equipment>

  FIG. 1 is a schematic perspective view showing a configuration of an exercise equipment 1 according to an embodiment of the present invention. FIG. 2 is a schematic plan view of the exercise device 1 shown in FIG. 1 when viewed from a plurality of directions. FIG. 2A is a view of the exercise device 1 as viewed from the left side. FIG.2 (b) is the figure which looked at the exercise equipment 1 from back. FIG.2 (c) is the figure which looked at the exercise equipment 1 from the bottom.

  As shown in FIGS. 1 and 2, the exercise device 1 includes a base 10 that is placed on the floor surface. The base portion 10 includes a first bar 101 extending in the front-rear direction, and a pair of second bars 102, 102 that are disposed at both ends of the first bar 101 and extend in the left-right direction. . In the present embodiment, the base portion 10 is substantially H-shaped in plan view, but is not limited to this shape, as long as the exercise equipment 1 can be stably placed on the floor surface. Other shapes may be used.

  A support column 103 extending in the up-down direction is erected slightly forward from the center of the first bar 101 constituting the base unit 10. A depression 103a is provided in the upper part of the support column 103, and the support column 103 has a substantially concave shape when viewed from the front-rear direction. A part of the rail portion 11 is fitted in the recess 103a.

  The rail part 11 is attached to the base part 10 so that the inclination angle with respect to the floor surface on which the base part 10 is placed can be adjusted. Specifically, the rail portion 11 includes a rail 111 and a rail support base 112 that is disposed on the lower side of the rail 111 and supports the rail 111. The rail support base 112 is fitted in the recess 103 a of the support column 103 in the vicinity of the front end. The support shaft 13 is fixed to the left and right side surfaces thereof and the rotating shaft 13 that passes through the rail support 112 fitted in the recess 103a. The rail support 112 is rotatable with respect to the rotation shaft 13. For this reason, the rail part 11 is supported by the base part 10 so that rotation is possible.

  The inclination adjustment of the rail portion 11 is performed using a gas spring 14 (an example of an inclination adjustment means) disposed between the base portion 10 and the rail portion 11. The gas spring 14 includes a cylinder 141 and a piston rod 142 partly housed in the cylinder 141. The rear end of the cylinder 141 (the end opposite to the side where the piston rod 142 enters and exits) is rotatably supported by the rear end of the rail support 112. Further, the tip end portion of the piston rod 142 is rotatably supported in the vicinity of the center portion of the first bar 101 constituting the base portion 10 (behind the support column 103).

  FIG. 3 is a schematic view for explaining the operation of the gas spring 14 provided in the exercise apparatus 1 according to the embodiment of the present invention. FIG. 3A is a perspective view seen from the upper left and FIG. 3B is a side view seen from the left side. When the protrusion amount of the piston rod 142 from the cylinder 141 increases from the state shown in FIG. 1 and FIG. 2, the rail portion 11 is lifted around the rotation shaft 13 as shown in FIG. ) In the counterclockwise direction). As a result, the inclination of the rail portion 11 with respect to the floor surface increases.

  The gas spring 14 has a lock function. When the lock function is activated, the piston rod 142 does not move relative to the cylinder 141. On the other hand, when the lock function is released, the protruding amount of the piston rod 142 from the cylinder 141 tends to increase due to the gas pressure (the piston rod 142 extends). However, when a force in the opposite direction larger than the gas pressure is applied to the piston rod 142 in the unlocked state, the amount by which the piston rod 142 protrudes from the cylinder 141 can be reduced (the piston rod 142 contracts). For this reason, the inclination angle with respect to the floor surface of the rail part 11 can be changed steplessly (continuously).

  For example, a push button can be used for the operation and release of the lock function. The lock function is activated when the push button is not pressed, and the lock function is released when the push button is pressed. Since the structure of the gas spring with a lock function is known, a detailed description is omitted here.

  As shown in FIGS. 1 and 2, a chair portion 15 is disposed on the rail portion 11. The chair portion 15 includes a seat portion 151 on which an exerciser places a buttocks, a backrest portion 152 that serves as a backrest for the exerciser sitting on the seat portion 151, and a grip portion 153 that is held by the exerciser sitting on the seat portion 151. And. The backrest 152 is preferably provided so as to be rotatable with respect to the seat 151 and has a so-called known reclining function. The inclination angle of the backrest part 152 with respect to the seat part 151 may be changed steplessly or may be changed stepwise. Further, the grip portion 153 is also preferably provided so as to be rotatable with respect to the seat portion 151, and it is preferable that the inclination angle of the grip portion 153 with respect to the seat portion 151 can be adjusted.

  As shown in FIG. 2, a slide mechanism portion 16 is provided on the lower surface of the seat portion 151. The slide mechanism portion 16 includes a roller support portion 161 fixed to the lower surface of the seat portion 151 and a plurality of rollers 162 supported by the roller support portion 161. In the present embodiment, as an example, the plurality of rollers 163 are provided on the left and right sides with the rail portion 11 interposed therebetween. Each roller 162 is attached to the roller support portion 161 such that the rotation axis thereof extends substantially in the vertical direction. Each roller 162 is in contact with the rail 111 at its side surface.

  FIG. 4 is a schematic diagram for explaining the operation of the slide mechanism unit 16 included in the exercise apparatus 1 according to the embodiment of the present invention. 4A is a perspective view seen from the upper left side, and FIG. 4B is a side view seen from the left side. When a force directed in the rear direction is applied to the chair portion 15 from the state illustrated in FIGS. 1 and 2, the chair portion 15 moves to the rear portion as illustrated in FIG. 4. On the other hand, since the rail part 11 is inclined with respect to the floor surface, the chair part 15 moved to the rear part moves forward due to its own weight. In addition, it is preferable that a stopper is provided in front of and behind the rail portion 11 so that the slide mechanism portion 16 and the rail portion 11 are not disengaged.

  As shown in FIGS. 1 and 2, a foot pressing portion 17 is disposed in front of the chair portion 15. The foot pressing portion 17 includes a foot plate 171 and a foot plate support portion 172 that supports the foot plate 171. The foot plate support portion 172 is a rod-like member bent in a substantially U shape. A foot plate 171 is fixed to one end of the foot plate support 172, and the other end is fixed to the rail support 112.

Note that the foot plate support 172 may be provided integrally with the rail support 112. Further, the foot plate support portion 172 may be attached to the rail support base 112 so that the position of the foot plate 171 in the front-rear direction can be adjusted. The foot plate 171 is supported by the foot plate support portion 172 so that the plate surface thereof faces the exerciser sitting on the chair portion 15. Since the foot pressing portion 17 is fixed to the rail portion 11, the foot plate 171 rotates with the rotation of the rail portion 11 (see FIGS. 2A and 3).
<Examples of using exercise equipment>

  Next, a usage example of the exercise equipment 1 configured as described above will be described with reference to FIG. Drawing 5 is a mimetic diagram for explaining an example of use of exercise equipment 1 concerning an embodiment of the present invention. Fig.5 (a) is a figure which shows the state in which the exerciser M became the attitude | position at the time of an exercise | movement start. FIG.5 (b) is a figure which shows the state which the exerciser M extended the leg (knee) for the exercise | movement from the state of Fig.5 (a).

  In starting the movement, the inclination angle of the rail portion 11 with respect to the floor surface is adjusted using the gas spring 14. The adjustment of the inclination angle is appropriately determined in consideration of the exercise intensity given to the exerciser M. Further, the angles of the backrest 152 and the grip 153 are appropriately adjusted according to the height of the athlete M and the like. Furthermore, if the position of the foot plate 17 can be adjusted, the position is appropriately adjusted according to the height of the athlete M and the like. In addition, each adjustment may be performed in a state where the exerciser M is sitting on the chair portion 15 as necessary.

  As shown in FIG. 5A, at the start of exercise, the exerciser M places the buttocks on the seat 151 and drowns on the backrest 152 (the back abuts against the backrest 152). Then, the exerciser M places both feet on the foot plate 171 fixed to the base 10 with the knee joint, hip joint, and the like bent at a predetermined angle (for example, 90 °). Specifically, the exerciser M attaches the sole of the foot to the plate surface of the foot plate 171 (the surface pressed by the foot). The exerciser M holds the grip portion 153 with his / her hand.

  From the state shown in FIG. 5 (a), the exerciser M pushes the foot plate 171 with both feet in such a manner that the knee is stretched. Due to this reaction force, the chair portion 15 on which the exerciser M is placed slides backward on the rail portion 11. Since the rail part 11 inclines with respect to a floor surface, when using the slide movement of the chair part 15 back, the load using the gravity is applied to the exerciser M. The load can be adjusted by selecting the inclination angle of the rail portion 11 with respect to the floor surface. For example, as shown in FIG. 6, when the inclination angle of the rail portion 11 is increased, the load applied to the exerciser M is increased when the knee is extended, as compared with the case of FIG.

In addition, when increasing the inclination angle with respect to the floor as shown in FIG. 6, it is preferable to increase the inclination angle of the backrest 152 with respect to the seat 151 as compared with the case of FIG. Accordingly, the exerciser M can safely press the foot plate 171 with his / her foot in a stable posture (see FIGS. 2A and 3B).
