Abstract

An object of the present invention is to provide a step board used for a stair provided with an elasticity effect by using a spring in order to reduce a weight burden on a knee or a foot when climbing up and down stairs. A stair climbing assisting tool attached to each step of a stair, comprising: a step plate (6) via a pedestal (1) having a resilient spring member (2) capable of exhibiting elasticity in a vertical direction attached to a floor of each step of the stair. Attach. The spring member is composed of at least one or more piano wires 2, one end of the spring member is fixed to the base 1, the other end of the spring member is slidably mounted on the base, and further fixed to the base. The other end of the spring member is mounted obliquely upward on the pedestal with respect to one end of the spring member, and the bending angle of the spring, which is the spring member, is increased to increase the elasticity of the stair climbing aid. .

Description

  The present invention relates to a footboard used for a staircase that uses a spring to give a resilient effect in order to reduce the weight burden on knees and feet when the stairs are raised and lowered.

  Although there are some differences among individuals, every time people get older, their knees and legs weaken, making it difficult to walk and climb stairs, making it painful. Therefore, conventionally, stair lifts using coil springs are commercially available. However, since an independent suspension mechanism is employed, the stability is poor and it is hardly used.

  Therefore, the present invention provides a stair lift support tool that can reduce the burden on the knees and feet as a result of intensive research on the drawbacks and problems of the conventional stair lift support tool.

The present invention is a stair climbing support tool that is attached to each step of a staircase, and a step board is attached to each step board floor surface through a pedestal that is attached with a spring member that can be elastically expressed in the vertical direction. A stair lift support tool characterized in that the spring member is composed of at least one piano wire, one end of the spring member is fixed to the pedestal, and the other end side of the spring member can slide on the pedestal Furthermore, the other end of the spring member is attached to the pedestal obliquely upward with respect to one end of the spring member fixed to the pedestal, thereby increasing the bending angle of the spring as the spring member. It is a stair climbing aid with enhanced elasticity.

  As described above, by laying the stair climbing aid according to the present invention on the staircase step board, when the stair is raised, the repulsive force of the stepped spring pushes the foot that has been stepped up together with the tread board to assist By doing so, even if the leg strength declined, it was possible to go to the upper stage and reduce the burden on the knees and feet.

  A specific example of the stair climbing aid according to the present invention will be described below with reference to FIGS.

Hereinafter, embodiments of the present invention will be described with specific examples. In this embodiment, one end of a spring (piano wire) 2 is attached to the base of an L-shaped spring pedestal 1 as shown in FIG. 1, and then the other end of the spring (piano wire) 2 as shown in FIG. The side was slidably inserted into a slide-type hole (spring insertion hole) 4 of the footboard attachment 3 and the footboard attachment 3 was fastened to the footboard 6 via the footboard mounting screw 5. Next, the base joint portion A on the base side of the L-shaped spring base 1 was fitted into the joint groove B for mounting the base engraved on the tread plate 6 shown in FIG.
Further, the L-shaped spring pedestal 1 was attached to the tread plate 6 via the step plate fixing element 8.

  4 shows the state of the L-shaped spring pedestal 1 which is the pedestal main body of the stair lift assisting tool according to the present invention and the tread board 6 arranged on the upper part of the spring 2, and FIG. The bending state of the spring pedestal 1 and the spring 2 is shown. Reference numeral 9 in the figure indicates a staircase, and reference numeral 10 indicates a foot.
