That is, in FIG. 8, symbol a is a column extending in the vertical direction, and four columns are arranged. Casters b are fixed to the lower end surfaces of the columns a. In addition, a handle C having a substantially U-shape is fixed to the upper end surface of each column a. In addition, reference numeral d is a substantially U-shaped reinforcing member, and the pillar b is reinforced by connecting the adjacent pillars b to each other by the reinforcing member d.

When performing walking training with the above-described walking assist device, the trainee enters the space defined by the handle c and the reinforcing member d and supports the body with the handle c by hand. Then, it walks while maintaining that state.

[0004]

Since the trainee who needs the above-mentioned walking aid has a lame leg, he / she often lives in a bed especially in a hospital or the like.
When such a trainee performs walking training with the above-mentioned walking aid, the walking aid is pulled near the bed so that the open portion of the handle c faces the bed side. Then, while holding the handle c with both hands and supporting the body, it enters the space defined by the handle c and the reinforcing member d. In this case, if the handle c is far from the trainee, the burden on both hands increases. Therefore, it is desirable for the walking aid to be such that the handle c can be located inside the side surface of the bed when pulled toward the bed.

However, in the above-mentioned conventional walking aid, the pillar a is disposed on the open side (rear end side) of the handle c, and when the pillar a pulls the walking aid to the bed, Hit the side. Therefore, there is a problem that the handle c cannot be pulled inward from the side surface of the bed.

If the portion up to is removed, the lower portion from the reinforcing member d gets under the bed when the walking assist device is pulled toward the bed. Therefore. The handle c can be pulled inward from the side of the bed. However, when the rear columns a and a are removed, the load applied to the handle c is supported only by the two front columns a and a, and the fixed portions of the columns a and c are not supported. A large bending stress is applied. Usually, the support a and the handle c are fixed by welding the support a to the lower surface of the handle c in a state where they are butted against each other, and the fixing portion has relatively low strength. For this reason, there is a possibility that the fixed portion may be destroyed.

The present invention has as its first object to solve the above problems. The first object of the invention is to provide a novel walking assist capable of pulling the handle to the inside of the side surface of the bed and having sufficiently high strength. To provide a container. Moreover, this invention makes it the 2nd objective to provide another walking aid which can perform gait training in the state leaning on leaning by using the above new walking aid, and also a walking aid.
