Description

  The present invention relates to a handrail auxiliary holder, and more particularly, to a handrail auxiliary holder that enables an elderly person or a handicapped person with weak grip strength to safely move up and down stairs while holding a handrail. It is.

  Conventionally, handrails have been provided to assist in raising and lowering in public facilities and household stairs.

  By the way, a long bar-shaped member having a predetermined cross-sectional shape such as a circle or an ellipse is usually used for the handrail, but this bar-shaped member is formed smoothly so that a pedestrian's hand is not caught. Therefore, particularly in the case of an elderly person with a weak grip and a handicapped person, there is a problem that a hand having a rod-like member slips and hinders walking.

In order to cope with this, it has also been proposed that the cross-sectional shape of the rod-shaped member is irregular (see, for example, Patent Document 1). In this case, the pedestrian will obtain from the rod-shaped member in order to maintain the balance of the body. Since the holding force direction coincides with the axial direction of the rod-shaped member, there is a problem that it is difficult to obtain a large holding force.
JP 2001-295444 A

  In view of the problems of the conventional handrails described above, the present invention makes it easy to obtain a holding force for maintaining the balance of the body, even for an elderly person or a handicapped person with weak grip strength, and safely An object of the present invention is to provide a handrail auxiliary holder that can be moved up and down.

  In order to achieve the above object, the handrail auxiliary holder of the present invention is a handrail auxiliary holder mainly composed of a long bar-like member, and the bar-like member constituting the handrail is provided with the bar-like member. It is characterized by comprising a gripping member that is mounted to protrude upward at a substantially right angle to the shaft.

  In this case, the gripping member can be composed of a straight bar-shaped piece.

  In addition, the gripping member can be constituted by a rod-shaped piece whose tip side is bent.

  According to the handrail auxiliary holder of the present invention, the pedestrian maintains the balance of the body because the grip member is attached by protruding upward substantially at right angles to the axis of the bar-shaped member constituting the handrail. Therefore, the holding force to be obtained from the rod-shaped member is obtained by projecting upward at a substantially right angle with respect to the axis of the rod-shaped member, and thereby being obtained via the grip member extending in the direction perpendicular to the direction of the holding force. Therefore, for example, even elderly people with weak grip and disabled people can easily obtain holding power to maintain the balance of the body, so that a hand with a handrail can slip and interfere with walking. It is possible to safely ascend and descend the stairs without any problems.

  In this case, by configuring the grip member from a straight bar-shaped piece, the desired effect can be obtained by the grip member having a simple structure.

  Also, by constructing the grip member from a rod-shaped piece bent at the tip side, the holding force for maintaining the balance of the body is easy for the distal pedestrian to hold the base and tip of the rod-shaped piece of the grip member. Therefore, it is possible to set the stairs up and down more safely.
