Description

  The present invention relates to an improved tread plate used for a staircase having a springy effect by using a spring 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.

  Utility Model Registration No. 3166164

  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 inventor has devised an improved tread board that solves the problem.

The present invention is a stair lift assisting tool that is attached to each step of a staircase, and is provided with a step board attached via a pedestal attached with a spring member that can be elastically expressed in the vertical direction on each step board floor. In the stair lift assisting tool, one end of the spring member is fixed to the pedestal and the other end side of the spring member is slidably mounted on the pedestal. This is a stair lift aid that wipes away the anxiety of the inclined footboard. Furthermore, a torsion coil spring was drilled in the lower part of the tread board of the stair lift assisting tool, a pin insertion hole was drilled in the round mounting plate in the lower part of the tread board, and a torsion coil spring strength adjustment pin was inserted into the pin insertion hole.

  As described above, a horizontal portion is formed on the upper surface of the step board of the stair lift assisting tool according to the present invention, and the anxiety of the inclined step board of the stair lift can be cleared. Furthermore, by inserting a torsion coil spring in the lower part of the tread plate of the stair lift assisting tool, and inserting a torsion coil spring strength adjustment pin in the multi-perforated pin insertion hole in the lower part of the tread board, the torsion coil spring is adjusted according to the inclination angle of the tread plate. The strength can be adjusted.

The perspective view which shows the basic principal part of the stair-climbing auxiliary tool which concerns on this invention The perspective view of a notch which shows the raising / lowering stabilization horizontal member mounted in the upper surface part of the tread of the stair-climbing auxiliary tool which concerns on this invention The side view which shows the operating condition of the step board of the stair-climbing auxiliary tool shown in FIG. Perspective view showing the bending footboard of the stair climbing aid It is a perspective view which shows the condition which has arrange | positioned the torsion coil spring which adjusts the angle of a tread board to the tread board of the stair-climbing auxiliary tool which concerns on this invention.

  A specific example of the stair lift support tool according to the present invention will be described below with reference to FIGS.

  In this embodiment, after attaching one end of a spring (piano wire) 2 to the base of an L-shaped spring pedestal 5 as shown in FIG. 1, the spring (piano wire) 2 as shown in FIGS. The other end of the slidable hole was slidably inserted into a slide type hole (spring insertion hole) 6A of the tread board attachment 6 and the tread board 8 was fastened to the tread board attachment 6 via the tread board attachment screw 6B. FIG. 3 shows a bent state of the bent horizontal lifting / lowering stabilizing portion 9 and the L-shaped spring 2 mounted on the upper part of the step board 8 of the stair lift support tool. In the figure, reference numeral 1 denotes a tread plate mounting plate, reference numeral 7 denotes a step plate mounting plate, reference numeral 10 denotes a slip stopper, and reference numeral 11 denotes a step. Next, FIG. 4 illustrates an example in which the step board 8 of the stair climbing assist tool is a bent step board 8A.

  FIG. 5 shows that a torsion coil spring 12 that adjusts the angle of the tread plate 8 is inserted into the step support plate 8 of the stair climbing assisting device according to the present invention into the pivot support plate 3 fixed to the round mounting plate 4, By attaching the torsion coil spring strength adjustment pin 13 to the dedicated mounting plate 4 in the perforated pin insertion hole 14, the angle of the horizontal portion of the upper surface of the tread plate can be adjusted according to the inclination angle of each staircase. The situation is illustrated. Reference numeral 15 in the figure denotes a tread board installation base, and reference numeral 16 denotes a staircase skeleton.
