Japanese Patent Laid-Open No. 7-222827

  However, with conventional training devices, it is difficult for a person who does not have normal exercise ability to sit on an unstable balance board, so an elderly person or other person with low exercise ability can perform ankle training. There wasn't.

  Accordingly, an object of the present invention is to provide a training device that can easily perform ankle training even for a person with low exercise ability.

  In order to solve the above-described problems, a training apparatus according to the present invention includes a placement plate on which a user's foot is placed, a swing shaft provided so as to protrude from the placement plate, and a swing shaft that swings the swing shaft. A support base that is movably supported, and an elastic member is provided between the support base and the mounting plate that biases the mounting plate tilted by the user to return to the initial position. It is characterized by being.

  According to the present invention, when the user puts his / her foot on the mounting plate and tilts the ankle in the front / rear and left / right directions, the elastic member contracts, and the return force (biasing force) becomes a load on the user's ankle. That is, since the user stands up on the balance plate as in the prior art, the exercising force of the elastic member is used as a load compared to the one that trains the ankle with the load of the user's own weight, so the exercise ability is low. Even if it is a person, for example, if the ankle is tilted by placing the foot on the mounting plate while sitting, the ankle can be easily trained.

  In the present invention, the rocking shaft and the support base may be rotatably connected via a sphere and a recess.

  According to this, when the user puts his / her foot on the mounting plate and tilts the ankle back and forth and right and left, the mounting plate tilts around the sphere. That is, since the sphere and the recess slide during ankle training, the wear of the sliding part is suppressed compared to the conventional structure in which the sharp tip of the conical support and the balance plate slide. Can do.

  Moreover, in this invention, you may further provide the retaining part which prevents that the said spherical body escapes from the said recessed part.

  According to this, since the sphere is prevented from falling out of the recess by the retaining portion, the training apparatus can be made easier to handle.

  In the present invention, the upper surface of the mounting plate may be covered with a heat insulating member.

  According to this, even when the mounting plate is very cold when using the training device in a low ambient temperature such as in winter, the heat of the user's foot is Is suppressed by the mounting plate, so that the user can perform training comfortably.

  According to the present invention, since the urging force of the elastic member is used as a load, even if the person has low exercise ability, if the ankle is tilted by placing the foot on the mounting plate in a stable posture, Training can be done.

  Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In the drawings to be referred to, FIG. 1 is an exploded perspective view showing a training apparatus according to the present embodiment, and FIG. 2 is a cross-sectional view showing the training apparatus.

  As shown in FIG. 1, the training apparatus 1 includes a mounting plate 10, a swing shaft 20, a support base 30, a retaining plate 40, a cover 50, and a coil spring S as an example of an elastic member. .

A cylindrical tubular member 32 fitted along the inner peripheral surface of the recessed portion 31 and a bottom plate 33 inserted along the inner surface of the tubular member 32 are provided in the recessed portion 31. Thereby, the spherical portion 22 of the swing shaft 20 is rotatably supported by the recess 31 via the cylindrical member 32 and the bottom plate 33, and the swing shaft 20 is swingably supported by the support base 30. It has become so. The cylindrical member 32 and the bottom plate 33 are both made of resin, whereas the swing shaft 20 is made of a material different from the resin, for example, stainless steel. Therefore, the slidability between the spherical portion 22 of the swing shaft 20, the cylindrical member 32, and the bottom plate 33 is good. In addition, the use of stainless steel can suppress the occurrence of rust and the like due to long-term use.

  Note that the cylindrical member 32 and the bottom plate 33 may be formed in an integral bottomed cylindrical shape. However, in this case, since it is necessary to form an air vent hole in the bottom of the recess 31 in order to fit the bottomed cylindrical member into the recess 31, the tubular member as in the present embodiment. 32 and the bottom plate 33 are preferably configured separately.

  The retaining plate 40 is formed in a disk shape, and an engaging recess 41 that engages with the other end (lower end) of the coil spring S is formed at the center thereof. In addition, a hole that gradually increases in diameter as it goes downward is formed in the bottom portion of the engagement recess 41 so as to penetrate vertically, and a portion that forms the inner surface of the tapered hole is a sphere of the swing shaft 20. A retaining portion 42 is provided on the upper half surface of the portion 22 so as to face vertically. The retaining plate 40 is fixed to the support base 30 by four bolts B. In this fixed state, the retaining portion 42 restricts the upward movement of the spherical portion 22 of the swing shaft 20. The spherical portion 22 is prevented from coming off from the recess 31.

  The cover 50 is formed of a nonmetal (a heat insulating member) such as rubber or sponge, and includes a bottomed cylindrical cover portion 51 and a flange portion 52 extending radially inward from the opening edge of the cover portion 51. Configured. The cover 50 is attached so as to cover the mounting plate 10 from above, thereby covering the upper surface and the outer peripheral surface of the mounting plate 10.

  The coil spring S is provided between the support base 30 and the mounting plate 10, specifically, between the retaining plate 40 and the mounting plate 10, and the mounting plate 10 is placed at the initial position (the lower surface of the support base 30 and It is configured to be biased so as to return to a parallel position. That is, the coil spring S is provided between the retaining plate 40 and the mounting plate 10 in a natural state (no-load state) or in a contracted state by a predetermined amount, so that the user tilts the mounting plate 10. At this time, the mounting plate 10 is returned to the initial position by the return force.

Next, a method for assembling the training device 1 will be described.
As shown in FIG. 1, a cylindrical member 32 and a bottom plate 33 (see FIG. 2) are attached to the recess 31 of the support base 30. Thereafter, the spherical portion 22 of the swing shaft 20 is inserted into the recess 31, and the center hole (engagement recess 41 and retainer 42) of the retaining plate 40 is passed through the shaft portion 21 of the swing shaft 20. The retaining plate 40 is set on the upper surface of the support base 30 and fixed with bolts B.

  Thereafter, the coil spring S is inserted from the distal end side of the shaft portion 21 of the swing shaft 20 and set in the engagement recess 41 of the retaining plate 40. Then, the mounting plate 10 is set at the tip (upper end) of the swing shaft 20 and the coil spring S, and the mounting plate 10 is fixed to the swing shaft 20 with screws N. Thereafter, the assembly of the training apparatus 1 is completed by covering the mounting plate 10 with the cover 50. When exchanging the coil spring S with a different type, the coil spring S can be exchanged by simply removing the cover 50, the screw N, and the mounting plate 10 in order.

  Next, a method for using the training apparatus 1 will be described. In the drawings to be referred to, FIG. 3 is a sectional view showing a state where the user tilts the ankle forward, and FIG. 4 is a sectional view showing a form in which both ankles are trained simultaneously.

  As shown in FIG. 3, for example, in a state where the user is sitting on a chair, the user places the area around the arch on the sole of one foot on the placing plate 10 (cover 50). Thereafter, when the ankle is tilted back and forth and right and left (tilt forward in the figure), the load of the coil spring S is applied to the ankle, and the ankle can be trained. After tilting the ankle in the forward / backward / left / right direction, the user can remove the force, and the ankle is returned to the initial position by the urging force of the coil spring S, which makes the operation smooth and effective training. It can be performed.

  When the user wants to increase the load applied to the ankle, the mounting plate 10 or the like may be removed and the coil spring S may be replaced as described above. If it is desired to train both ankles, two training devices 1 may be prepared and each foot may be placed on each training device 1. Furthermore, when it is desired to train both ankles at the same time, for example, as shown in FIG. 4, a plate 60 is placed so as to straddle the upper surface of each training apparatus 1, and training can be performed by placing both feet on the plate 60. It can be carried out. According to this, since both ankles can be tilted simultaneously in each direction, both ankles can be trained with good balance. It is desirable that the plate 60 be fixed to the placement plate 10 of each training apparatus 1 with a bolt or the like.
