Abstract

Provided is a stair lift support tool attached to each step on a stair, which is provided with a resilient effect in order to reduce the weight burden on knees and feet when the stair is lifted. After attaching one end of a spring (piano wire) to the base of an L-shaped spring fixing base, the other end of the spring (piano wire) is connected to a slide hole (spring) of a spring slide bar. The front footboard was attached to the spring slide rod 7 via the footboard mounting screw 9. The front tread plate mounting plate 14 is inserted into the free portion insertion hole of the fixed tread plate mounting plate 11 through the universal portion 1 of the pivot support.

Description

  The present invention relates to an improved tread board used for a stair to which a resilient effect is imparted by using a spring (piano wire or the like) 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. For this reason, conventionally, stair lifts using coil springs are commercially available, but since an independent suspension mechanism is employed, the stability is scarce and hardly used.

  As a result of diligent research on the drawbacks and problems of the conventional stair lift support tool, the inventor has been able to provide a stair lift support tool that can reduce the burden on the knees and feet. Therefore, when the prototype was mounted on the test stairs and the test riders were asked to take a questionnaire, there was an opinion that the tread board attached to the stairs was inclined, so it felt somewhat scary, The present inventor previously devised an improved tread to solve the problem, but further devised an improved tread to eliminate the problem.

The present invention is a stair lift assisting tool attached to each step of a staircase, and a step board is attached to each step board floor surface through a pedestal attached with a resilient spring member that can be elastically expressed in the vertical direction. In the stair lift support tool, the step plate of the stair lift support tool is divided into a front part and a rear part. The front part of the step board has one end of a spring member fixed to the base, and the other end side of the spring member is a slide bar on the step board. Slidably mounted, the rear portion of the tread plate forms a horizontal portion on the upper surface portion of the rear tread plate mounting plate, and is fixed to the fixed tread plate mounting plate via the pedestal, A stair-climbing assisting tool, which is rotatably attached via a shaft support round bar inserted into the fixed tread plate mounting plate standing on the pedestal.

  As described above, the rear step board of the stair lift assisting tool according to the present invention has the horizontal portion formed on the upper surface of the rear step board mounting plate, so that the stability equivalent to that of a normal stair can be reliably maintained.

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

In this embodiment, one end of a spring (piano wire) 6 is attached to the base of an L-shaped spring fixing base 10 as shown in FIG. 1, and then the other of the spring (piano wire) 6 as shown in FIG. The end side was slidably inserted into a slide hole (spring insertion hole) 8 of the spring slide bar 7, and the front tread plate 5 was attached to the spring slide rod 7 via a tread plate mounting screw 9. FIG. 2 illustrates a state in which the front footboard mounting plate 14 is inserted into the free part insertion hole 16 of the fixed footboard mounting plate 11 through the free part 1 of the pivot support 3.

FIG. 3 shows a state where the step board of the stair climbing assist tool is divided into the front step board 5 and the rear horizontal step board 4 and attached to the spring 6 slide bar 7. FIG. 4 shows a state in which the front tread plate 5 of the stair lift support tool is mounted on the spring fixing base 10. FIG. 5 shows a state before the foot 13 is stepped on when the person steps on the front step board 5 of the stair lift support tool according to the present invention, and FIG. 6 shows a state when the person steps on the front step board 5 of the step lift support tool. The situation where the foot 13 is depressed is shown. Reference numeral 2 in FIG. 1 denotes a rear footboard mounting plate, and reference numeral 12 denotes a step plate mounting plate. Reference numeral 15 in FIG. 6 illustrates a slip stopper.
