Abstract

PURPOSE:To make it possible to pull up one's body effectively without producing a slip by forming a grip which is inclined relatively horizontally or vertically to a slope angle of a staircase. CONSTITUTION:Rod-shaped hand rails 2 are installed over the whole area of a staircase in the upper part of a side wall 5 of a staircase 1. Grips 3, which comprise rod-shaped members, are installed directly in the upper part of the hand rails 2 in the vertical direction, and what is more, a plurality of grips are installed to comply with the steps of the staircase 1 with a spacing separated from each other. The length of the grips 3 are arranged to be equivalent to the number of steps of the staircase 1 while they are arranged to be located slightly on a rising side from steps 4. This construction makes it possible to reduce power which exerts to leg muscles, and what is more, to be less slippery since the grips are vertical in shape. In addition, as for the spacing between the handrails 2 and the grips 3 it is better to set their dimension so that a human hand may pass through the spacing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail structure for stairs, and more particularly to an improvement of a grip portion structure for reliably assisting a lifting operation.

[0002]

2. Description of the Related Art Conventionally, as a handrail structure for stairs, FIG.
The structure shown in is generally adopted. That is, the bar-shaped handrail 2 is installed parallel to the inclination angle of the stairs 1, and by grasping this, it is intended to reduce the load applied to the legs when moving up and down the stairs.

[0003]

[Problems to be Solved by the Invention] Now, let us consider concretely the assisting operation by hand when going up and down stairs. When you go up the stairs, you can grasp the action of holding the handrail to pull up your body, and when you go down the stairs you can grasp the action of holding the handrail to support your body as an assist action.
It can be said that it is necessary to hold the handrail in any movement.

However, in the above-mentioned conventional handrail structure,
Since the grip is parallel to the slope of the stairs, the force that assists the lifting operation works toward the lower part of the handrail, and as a result, it is relatively slippery, and the force of the arm does not efficiently affect the assisting force. It has the drawback of

In this case, in the case of an adult whose legs are relatively strong,
The handrails are rarely used when climbing the stairs, and even if they are used for a car, they do not require very strong assist, and because they have sufficient grip, the above-mentioned drawbacks do not become a big problem.

However, in the case of an elderly person whose legs and waist are weakened, a handrail is used to move up and down the stairs, and an action that relies heavily on the arm is required. Moreover, since the grip and arm strength of the old man is relatively weaker than that of an adult, the slipperiness, which is a drawback of the conventional handrail, can be said to be a big problem when climbing stairs.

In order to solve this problem, it can be considered that the surface of the handrail is made of a non-slip material such as rubber. With this configuration, it is possible to prevent slipping to some extent, but since the grip is still inclined,
We cannot solve the drawback that the force of the arm does not work efficiently to support the body.

The present invention has been made in view of the above problems of the conventional handrail structure, and an object of the present invention is to provide a handrail structure capable of sufficiently assisting the stair climbing motion even for an elderly person.

[0009]

According to the present invention, as a result of analyzing how to use a handrail when going up and down stairs, the handgrip of the handrail can be shaped so that a force is always applied in the vertical direction when the handrail is gripped. This handrail structure was completed after discovering that it is important for increasing assist, and is a handrail structure in which a grip part that is inclined horizontally or vertically relative to the inclination angle of the stairs is formed. The grip portion may have only a horizontal portion or a vertical portion, but it is preferable that both are alternately provided over the entire step portion of the stairs.

[0010]

According to the present invention, the horizontal handrail is capable of supporting the body by placing the hand on the stairs when descending stairs, and the grip force is not required so much. In addition, the vertical handrail allows the body to be effectively pulled up without slipping by grasping and pulling it when climbing stairs.

As for the handrail structure, horizontal portions and vertical portions, which are grip portions, may be alternately and continuously formed corresponding to the steps of stairs, but they are attached to a member formed in a cross section. Form a part to make one gripping member, and install it by the number corresponding to the number of steps of the stairs, so that the handrail can be constructed with a common gripping member even for buildings with different steps of stairs. You can

By the way, the position of the horizontal part or the vertical part forming the handrail with respect to the stairs can take various positions depending on the nature of the person using the stairs, especially the characteristics of the posture. For example, in the forward leaning position, the vertical part would have to be set further forward (uphill) with respect to the steps of the stairs. Therefore, in the present invention, by providing the grip member with the mounting portion whose mounting position is variable, it is possible to provide the handrail structure according to the body position of the group using the stairs.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, in which a grip portion extending in the vertical direction is additionally installed in addition to the conventional handrail. Reference numeral 1 is a staircase, and a bar-shaped handrail 2 is provided above the side wall 5 of the staircase 1 over the entire area of the staircase. Further, a grip portion 3 made of a rod-shaped member is provided immediately above the handrail 2.
Are installed in a vertical direction and at a plurality of intervals corresponding to the steps of the stairs. The grip portion 3 has a length that is substantially equal to the step of the stairs 1, and is located slightly on the climbing side of the step portion 4 of the stairs 1. This makes it possible to reduce the load applied to the legs and waist by gripping the grip portion 3 with the hand when climbing the stairs, and moreover, since the grip portion is vertical, it does not slip. In addition, handrail 2
The gap between the grip 3 and the grip 3 is, for example, 10
It is preferable to set it to about 0 mm.

FIG. 2 shows a second embodiment of the present invention.
As the structure of the handrail 6, a plurality of grip portions 7 extending substantially horizontally are installed in a spaced manner corresponding to the step portions 4 of the stairs 1. The grip part 7 is composed of a horizontal part 7b and a slightly inclined part 7a, and adjacent grip parts overlap each other at their ends. The grip portion of this embodiment is mainly excellent in the function of supporting the body, and since the part to which the body weight is applied is horizontal, the hands do not slip when supporting the body, and reliable assist is provided both when climbing and descending stairs. You can do it.

FIG. 3 shows a third embodiment of the present invention.
The structure of the handrail 8 in which a horizontal portion and a vertical portion 9 are formed is shown. In the figure, the handrail 8 of the staircase 1 has a structure in which a vertical part 9b and a horizontal part 9a corresponding to the step part of the staircase are continuously formed over the entire area of the staircase 1 as a grip portion. ing. The height of the vertical portion 9b is set to be substantially equal to the step H of the stairs 1, and the length of the horizontal portion 9a is set to be substantially equal to the step width W of the stairs 1.
Also, the positional relationship of this handrail to the stairs is
b, the horizontal portion 9a is set to be offset by a predetermined amount D to the ascending side compared to that of the stairs 1, and the predetermined amount D is preferably set within a range of half the step width of the stairs 1 or less. In the embodiment configured as described above, the assisting force can be surely obtained by grasping the vertical portion 9b when climbing the stairs, and it is possible to surely obtain the assisting force by climbing the horizontal portion 9a when descending the stairs. It has the effect of supporting the body.

FIG. 4 shows a fourth embodiment of the present invention.
As a modified example of the third embodiment, the grip portions are installed separately. Although it is the same as that of the third embodiment as a whole, the handrail 10 is not continuous, and a plurality of grip portions 11 are installed at intervals according to the steps of the stairs 1. The grip portion 11 is composed of a vertical portion 11b and a horizontal portion 11a.
Is slightly vertical rather than perfectly vertical. This is more versatile than the third embodiment because the most suitable grip position of the vertical portion can be selected when climbing stairs. The installation position, the size of each part, and the basic usage when climbing the stairs are the same as in the third embodiment. However, in this embodiment, since the grip portion 11 is independent as one member, even when the handrails of stairs having different numbers of stairs are configured, they can be configured by common members, which has an effect of cost reduction. is doing.

FIG. 5 shows the details of the grip portion 11 in FIG. 4, and explains the mounting portion. In the figure, mounting holes 12a, 12 are provided at both ends of the horizontal portion 11a of the grip portion 11 as mounting portions for mounting the grip portion on a wall or the like.
