DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a patient with a weakened lower limb or an elderly person who walks without assistance from an attendant, or a person with a disease on the lower limb who walks without assistance from an attendant. For example, the present invention relates to the provision of a walking assist device used when performing the movement.

[0002]

2. Description of the Related Art When an elderly person with a weakened lower limb, a sick person, or a disabled person having a sickness in the lower limb is moved, for example, appropriate moving means such as a wheelchair is used. Access means such as wheelchairs are provided in various facilities.

[0003] However, in facilities other than public facilities, for example, general private homes, various private facilities, or conventional public facilities, most of them are facilities that are assumed to be used by healthy persons. In many cases, facilities that are suitable for comfortable use of persons with difficulty in walking are not provided, and some of the facilities are provided with handrails for walking assistance only in, for example, corridors.

[0004]

However, this type of handrail for assisting walking is generally premised on equipment such as a wall provided with the handrail, and is used for assisting walking in areas without walls. There was difficulty in setting up the equipment.

[0005] In addition, a handrail configured as an assisting means for walking requires that a pedestrian who stands up along the handrail moves while grasping from above with the handrail as a support.
It was not satisfactory as a walking aid for people with disabilities who could not get up.

[0006] Also, the handrail to be provided is usually fixed to a wall or the like, and the height of the handrail is adjusted as needed according to the height of each pedestrian, the degree of obstacles to the pedestrian, and the like. There was a problem that could not be adjusted.

Further, when handrails are provided along the wall surface of a corridor or the like, the effective use width of the corridor or the like is reduced, which impairs comfortable operability in a living space, and when carrying in and out various articles such as furniture. There were difficulties such as the installation handrail becoming an obstacle.

According to the present invention, by utilizing a ceiling portion of a structure such as a building, a walking assist device can be optionally provided at an arbitrary position other than a wall, as needed.
Moreover, it is an object of the present invention to provide a walking assist device that does not narrow the occupant's working space and is capable of supporting the body at a relatively high position.

[0009]

According to the present invention, in order to achieve the above-mentioned characteristic object, a walking assist device according to the first aspect of the present invention comprises a guide rail A on a ceiling D of a structure such as a building. At the same time, a guide means B movably provided on the guide rail A is provided with a holding means C for holding a pedestrian when moving, in a hanging state.

Next, in the walking assist device according to the second aspect of the present invention, the wheel 20 of the guide B which is rolled and guided in the guide groove 12 of the guide rail A is provided. When the pedestrian pulls and grips the gripping means C of the guide B, the guide B is elastically deformed so as to be in close contact with the surface of the guide groove 12.

Further, in the walking assist device according to the third aspect of the present invention, in the walking assist device according to the first aspect of the present invention, the wheel 20 provided on the guide B has an annular grounding wheel 21 that is elastically deformed. The guide groove 12 of the guide rail A, which is provided on the outer periphery and rolls and guides the wheel 20 of the guide B, has a receiving recess 12a of an elastically deformable portion of the annular grounding wheel 21 which is elastically deformed. It is prepared for the side inside.
