Here, although all of the conventional health appliances can support the knee joint at an appropriate height from below, it is difficult to actively assist the knee joint flexion movement.

Specifically, in Patent Document 1, since the entire thigh portion and calf portion are supported across the knee joint, it is merely a cushion and does not actively promote the movement of the knee joint.

In the above-mentioned Patent Document 2, the knee joint is supported by a pipe from directly below, and the knee joint is suspended, and conversely, the knee joint is not hung up, and the knee joint is not actively promoted to bend. It was.

However, in Patent Document 2, it is possible to move the knee joint by supporting only the knee joint of one leg on the pipe and entangle the other leg (under the pipe) with one leg. However, it was impossible to assist the appropriate flexion movement because the suspended foot where only the knee joint was supported by the pipe was pulled from the bottom, and the load on the knee joint was excessive.

In view of the above circumstances, an object of the present invention is to provide a health device capable of assisting positive and appropriate flexion movement of the knee joint and a method for using the same.

When the support is sandwiched under the knee of the user, the base angle on the toe side is It is larger than the diagonal and smaller than the base angle on the thigh side.

According to the health device of the first aspect of the invention, the support having one side of the triangular prism as the bottom is a width with which one knee is supported, and the cross-section is a triangle having the acute angle diagonally with the one side as the base. When placed under the knee, the base angle on the toe side is arranged to be larger than the diagonal and smaller than the base angle on the thigh side. Therefore, it is possible to form an appropriate gap space on the placement surface side that allows movement of the knee joint while supporting the knee joint and the front and back thereof along the side of the triangular column along the thigh and calf with the knee standing.

And, it is attached to the toe side of the user's knee, and the toe side is pulled to the thigh side by an assisting tool that the user can draw, so that it is an active flexion movement of the knee joint, but in the range of the gap space. The knee joint can be flexed without excessive load on the knee joint.

As shown in FIGS. 1 and 2, the health device of the present embodiment is a health device that can exercise the knee joint while supporting the knee joint in a state where the user is lying on his back or sitting, A support body 1 having one side surface of a triangular prism as a bottom surface 11 and an auxiliary tool 2 that is attached to the toe side of the user's knee and can be pulled by the user.

The support 1 is made of, for example, a member made of urethane or synthetic resin (foamed resin), and has a width W where one knee is supported, and the cross section is a triangle with a diagonal angle θ1 having one side 11 as a base and an acute angle. Thus, when sandwiched under the knee of the user, the toe side base angle θ2 is larger than the diagonal angle θ1 and smaller than the thigh side base angle θ3.

Diagonal θ1 is the smallest angle among the three interior angles, and is selected from 10 ° to 40 °, more preferably selected from 15 ° to 25 °, taking into account the load of flexion movement of the knee joint, When it is desired to reduce the load, a larger angle is selected. When it is desired to increase the load, a smaller angle is selected.

The base angle θ2 is selected from 50 ° to 80 °, more preferably from 65 ° to 75 °. The base angle θ3 of the maximum angle is selected from 70 ° to 90 °, more preferably from 80 ° to 90 °.

Here, by selecting the diagonal θ1 and the base angles θ2 and θ3 from the above range so as to satisfy the above relationship, the user can support the knee joint immediately above the diagonal θ1 in a kneeling state. The side surface 12 located on the thigh side supports a part of the thigh continuously from the knee joint, and the side surface 13 on the toe side supports a part of the calf continuously from the knee joint.

At this time, in the kneeling posture, the person has an inclination angle on the thigh side with respect to the inclination angle on the toe side across the knee joint. Therefore, by setting the base angle θ3 of the support 1 to 70 ° to 90 ° (preferably 80 ° to 90 °) and the base angle θ2 to 50 ° to 80 ° (preferably 65 ° to 75 °), The side surface 12 can extend along the thigh more widely, and the side surface 13 can extend along the calf wider.

This makes it possible to stably support the knee joint and its front and back along the side surfaces 12 and 13 of the triangular prism on the thigh and calf, giving a sense of security to the user using the health device.

Further, at this time, moderate gap spaces S2 and S3 that allow the movement of the knee joint are formed between the mounting surface of the support body 1 and the thigh and the calf, and in the range of the gap spaces S2 and S3, The user can perform a flexion movement of the knee joint.

Next, the assisting device 2 assists such a bending motion, and if it can be brought into contact with or wound around the toe side of the knee and pulled under the knee, a towel or a towel, etc. It may be a thing.
