Both ends of the belt 20 extending on both sides in the front-rear direction of the frame 12 are looped under the seat portion 92 and connected by the buckles 23 . That is, the belt 20 is wound around in the front-rear direction. Finally, the user 99 removes slack in the belt 20 with the adjuster 22 and fastens the frame 12 to the seat portion 92 (seat surface 91 ) with the belt 20 .

As described above, the exercise assistance device 1 is fixed on the seat surface 91 .

[Training without exercise aids]
Next, before explaining how to use the exercise aid 1, a case where the exercise aid 1 is not used and only the chair 90 is used for standing training will be described with reference to FIG. FIG. 9 is a side view for explaining standing-up training without using the exercise aid 1. FIG.

First, in the present specification, the “stand-up motion” is the motion of the user 99 seated on the seat surface 91 of the chair 90 until the user 99 separates the buttocks 99A from the seat surface 91 and stands up. It should be noted that the standing posture (standing posture) does not need to have the knees stretched, and may be a posture in which the knees are bent and the body is bent forward. Further, in this specification, "training of standing motion" means to repeat the above-described standing motion and sitting motion to improve the muscle strength of the lower limbs (mainly the quadriceps femoris).

When training the standing motion without using the exercise aid 1, the user 99 of the chair 90 sits shallowly on the seat surface 91, corrects the posture of the upper body, and puts both hands on the knees (Fig. 9 (1)). The user 99 is seated and tilts the upper half of the body forward while pulling the heel backward (see (2) in FIG. 9). The user 99 moves the center of gravity forward, pushes the floor with the feet, separates the buttocks 99A from the seat surface 91, and stands on his/her own legs (see (3) and (4) in FIG. 9). After that, the user 99 sits on the seat surface 91 again (see (1) and (2) in FIG. 9). Thereafter, the user 99 repeats standing up and sitting down.

Here, when the user 99 stands up, a larger load is applied to the lower limbs (muscles, etc.) of the user 99 than when the user 99 is seated. Moreover, the user 99 shifts from a stable posture (see (1) and (2) in FIG. 9) in which most of the weight is placed on the seat surface 91 to an unstable posture in which the user's entire weight must be supported by both legs. (See (3) in FIG. 9), so not only a large load is applied to the lower limbs, but also the stability (balance) changes greatly. If the user 99 has the muscle strength necessary to stand up, he/she can cope with the load on the lower limbs and the change in stability described above, and can stand up from the state in which the buttocks 99A are in contact with the seat surface 91. However, some elderly people with weakened legs and people with disabilities in the lower limbs cannot cope with the above-described changes in the load on the lower limbs and stability, and the buttocks 99A are brought into contact with the seat surface 91. Sometimes it is difficult to stand up from the state (see (2) in FIG. 9).

[How to use exercise aids]
In order to solve the above problems, the exercise assisting device 1 according to the first embodiment reduces the amount of change in the load on the lower limbs and the stability, so that even a person whose leg strength has weakened can train to stand up. making it possible. A method of using the exercise aid 1 will be described with reference to FIG. 6 . FIG. 6 is a side view explaining how to use the exercise aid 1. FIG.

The user 99 adjusts the inclination angle of the receiving surface portion 10 according to his or her physical ability (leg strength). For example, for persons with significantly weakened leg strength or severe disabilities, the inclination angle (X2) of the receiving surface 10 is set large (close to vertical) (see FIG. 4), and persons with slightly weakened leg strength or For persons with mild disabilities, the tilt angle (X3) of the receiving surface 10 is set small (close to horizontal) (see FIG. 5).

Next, the user 99 sits on the inclined receiving surface 10, corrects the posture of the upper half of the body, and puts both hands on the knees (see (1) in FIG. 6). At this time, since the receiving surface portion 10 is inclined, the user 99 does not sit firmly on the receiving surface portion 10, but leans on the receiving surface portion 10 and contacts the buttocks 99A with the receiving surface portion 10. Let Therefore, the load applied to the lower limbs (legs) of the user 99 is greater than when the user is seated on the seat surface 91 of the chair 90 and less than when the user is standing. The user 99 sits on the receiving surface 10 and tilts the upper half of the body forward while pulling the heel backward (see (2) in FIG. 6). The user 99 moves the center of gravity forward, pushes the floor with the feet, separates the buttocks 99A from the receiving surface 10, and stands on his/her own legs (see (3) and (4) in FIG. 6). After that, the user 99 sits on the receiving surface portion 10 again (see (1) and (2) in FIG. 6). Thereafter, the user 99 repeats standing up and sitting down.

According to the standing motion training using the exercise assistance device 1 according to the first embodiment described above, since the user 99 is lightly sitting on the receiving surface 10, a certain amount of load is applied to the lower extremities (legs). An action to wake up from the state can be initiated. As a result, in the process from sitting on the receiving surface 10 to standing, the load on the lower limbs and the amount of change in stability can be kept small. As a result, even an elderly person or the like whose leg strength has weakened can easily perform standing-up training.

Further, according to the exercise assisting device 1 according to the first embodiment, since the inclination angle (X1 to X3) of the receiving surface portion 10 can be changed stepwise, the user 99 other than the specific person can also perform the standing motion. Can be used for training. As a result, the standing motion training can be performed according to the leg strength of the user 99 and the degree of disability (physical ability). Moreover, since the exercise aid 1 is detachably attached to the seat surface 91 of the chair 90 , the exercise aid 1 can be removed from the seat surface 91 and used as a normal chair 90 . Furthermore, since the exercise assisting device 1 can be attached to a suitable chair 90 on site, the exercise can be performed anywhere.

Further, according to the exercise assisting device 1 according to the first embodiment, the holding portion 11 can be easily fixed on the seat surface 91 by fastening the holding portion 11 to the seat portion 92 with the belt 20 . Moreover, since the belt 20 can be manufactured at a lower cost than the clamping mechanism or the like, the manufacturing cost of the exercise assisting device 1 as a whole can be reduced.

Moreover, according to the exercise assistance device 1 according to the first embodiment, the length of the belt 20 can be adjusted with the adjuster 22 . As a result, the length of the belt 20 can be adjusted according to the size and shape of the seat portion 92 , so that the exercise assistance device 1 can be attached to various chairs 90 . In addition, since both ends of the belt 20 can be easily connected and separated by the buckle 23, the exercise assisting device 1 can be easily attached to and detached from the seat surface 91 of the chair 90. FIG. Furthermore, since the belt 20 is a separate member from the holding portion 11 and the like, for example, only the belt 20 can be replaced. Further, for example, the belt 20 can be always kept at a plurality of installation locations, and only the exercise assisting device 1 (the receiving surface portion 10 and the holding portion 11) other than the belt 20 can be carried around.

Further, according to the exercise assisting device 1 according to the first embodiment, the receiving surface portion 10 can be transformed into the storage form F2 in which the holding portion 11 and the holding portion 11 are arranged substantially on the same plane (see the upper part of FIG. 2). As a result, the operator can easily carry the exercise aid 1 deformed to the storage form F2, and by putting the exercise aid 1 into the storage form F2, when storing the exercise aid 1 that is not in use. It does not take up a lot of space, and the storage (storage) space can be saved.
