Description

  The present invention relates to a handrail, and more particularly to a handrail that can stand on its own.

  In recent years when the aging society has advanced, development of various welfare equipment has been progressing. In particular, it is very useful to assist standing, walking, etc. using handrails for elderly people with weak muscle strength. Conventionally, the handrail is generally fixed to a wall or the like. However, the type of handrail that is fixed to a wall or the like is not suitable for the purpose of assisting standing up and walking at any place because it is necessary to select an attachment place. Under such circumstances, as shown in Patent Document 1, a self-supporting handrail has been developed. Such a self-supporting handrail can be moved freely and can be placed at any place. For example, a self-supporting handrail can be arranged even in a place where there is no wall, such as near a bed, near a bed, or near a dining table. As a result, a person who needs assistance from a handrail, such as an elderly person or an injured person, can stand and walk while receiving assistance from the handrail.

Registered Utility Model No. 3095911 JP 2002-13270 A

  In the self-supporting handrail as described in Patent Document 1, the user cannot adjust the length of the handrail himself. Therefore, a self-supporting handrail having a length according to the user's request had to be manufactured. In the future, as an aging society progresses, freestanding handrails must be installed in every place, and a self-supporting handrail excellent in versatility that can freely change the length of the handrail is required. In FIG. 3 and paragraph 0015 of Patent Document 2, a handrail that can be adjusted in length is disclosed. However, the handrail rod described in Patent Document 2 adjusts the length by sliding the length adjustment rod, and the adjustable length is in a limited range. Therefore, an object of the present invention is to provide a self-supporting handrail that can freely change the length of the handrail.

  Conventional self-supporting handrails may get in the way when not in use. Therefore, an object of the present invention is to provide a self-supporting handrail that can be made compact so as not to get in the way when not in use.

  In the conventional self-supporting handrail, the inclination angle of the handrail is fixed. Typically, the inclination angle of the handrail is fixed horizontally. When a self-supporting handrail is installed in a place with a step, if the angle of the handrail can be freely changed depending on the level of the step, a self-supporting handrail with excellent versatility will be provided. Therefore, an object of the present invention is to provide a self-supporting handrail that can freely change the inclination angle of the handrail.

  The conventional self-supporting handrail has a structure in which a handrail is installed on a vertically extending column. Therefore, a support | pillar will extend from the edge part of a handrail perpendicularly. FIG. 1 of Patent Document 2 discloses a self-supporting handrail in which the support pillar does not extend vertically from the end of the handrail, but there is no change in that the support pillar extends vertically. If the struts extend vertically, the vertical struts may interfere with the movement. Therefore, an object of the present invention is to provide a self-supporting handrail that does not get in the way when moving.

  A conventional self-supporting handrail is attached only with a handrail. However, when walking with a handrail, you may have something. When moving by relying on a handrail while carrying an object in this way, there is a case where it is desired to temporarily place an object to be held somewhere. Therefore, an object of the present invention is to provide a self-supporting handrail capable of temporarily placing what it has.
