JPH09296578A - Step-shaped row for aiding ascending/descending step - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate ascending/descending of the aged by providing a sub step-shaped row whose height is specified to a main step on the main step as an auxiliary step. SOLUTION: An auxiliary step 1 which is a step-shaped row is provided on either side, on each side, or at a center of a normal step. Each step surface of the auxiliary step 1 is shifted at the height of 1/2 of the step difference to a proximal floor or each step surface of the normal step. The part before and behind the step surface is flush with the part before and behind the step surface of the normal step. When an aged person ascends the step provided with the auxiliary step 1 on the left side of the normal step, his/her left leg is placed on the step surface of the auxiliary step 1 and his/her right leg is placed on the step surface of the normal step, and ascends the step progressively, and in the reverse order when he/she descends the step, and ordinary persons ascend/descend the normal step. In addition, the auxiliary step 1 and a boundary part between the auxiliary step 1 and the normal step is colored, or a projection for blind persons is provided to improve the safety. Ascending/descending can be facilitated.

Description

Detailed Description of the Invention

[0001]

[0001] The present invention relates to a staircase. That is, indoors and outdoors such as residential buildings, offices, factories, workplaces, warehouses, schools, gymnasiums, stores, hotels, hospitals, nursing homes, museums, station buildings, etc., and undulating land, mountains / hills, shrines and temples It is related to a continuous corridor that is used for raising and lowering people by being installed in the entrances and exits of underground shopping streets and underground passages, pedestrian bridges, and inside vehicles such as buses and trains, aircraft and ships.

[0002]

2. Description of the Related Art A conventional staircase is one for one staircase.
The steps are continuous in rows, and there is no structure in which further steps are added, such as staggered steps to assist the lifting.

[0003]

The stairs are used by various people, but most of the current stairs are designed according to the stride of the adult and the width of raising and lowering of the foot, so that the elderly and the physically disabled. It is not easy for people to use it because it has large steps. In addition, it may not be easy for a person with a short height, a woman who wears shoes such as high-heeled shoes that are likely to be unstable, and a child to easily move up and down. If the steps of the stairs are made smaller according to the elderly, the steps will be difficult for adults to use.

An object of the present invention is to make it easy for a person who feels that the steps of the stairs are too large and is inconvenient to raise and lower the stairs. At that time, it is also intended not to interfere with the lifting of a person who does not feel particularly inconvenient.

[0005]

In order to achieve the above object, in the present invention, a so-called sub-step-like row is provided as an auxiliary step in a so-called main stair so that the stairs can be easily moved up and down. Is.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an example and FIG. 2 is for reference. In the embodiment of FIG. 1, an auxiliary step (1), which is a step-like row, is provided on the left side of the normal stairs. The step surface of the auxiliary step (1) is offset from the floor in front of the normal stairs or each step surface of the normal stairs by half the height of the step, and before and after the step surface. Are aligned with the front and back of the normal stair step surface. When ascending, an elderly person or the like will have their left foot on the step surface of the auxiliary step (1) and their right foot on the step surface of a normal staircase in order to ascend. On the contrary, when getting off, the right foot is put on the step surface of the auxiliary step (1) and the left foot is put on the step surface of the normal stairs in order to get off. Now, focusing on only the movement of the right foot when climbing, the right foot is the step surface of the normal stairs, the step surface (2a), the step surface (2
b), the step surface (2c), and the step surface (2d) are traced in this order. When an ordinary person climbs this normal staircase, the right foot follows the step surface (2a) and then the step surface (2c) or the step surface (2b) and then the step surface (2d). If you do this, the number of times your feet are raised and lowered while moving at the same height will be half, but the width of each foot movement will be halved, and elderly people will use the stairs. Easier to do. If such an auxiliary step (1) is provided, it may be confusing to see two stair-like rows before starting to climb, and the step surface of the auxiliary step (1) and a normal step There is always a step with the surface, and there will be a step difference between the left and right with the climbing person in the middle, but the way of moving the left and right legs is not different from the case of climbing the normal stairs, for example The arrangement of the rod-shaped projections for raising and lowering on the electric poles and towers also causes a step difference on the left and right with the person in the middle ascending, so if you get used to it, you will lose the strange feeling. In the case of elderly people, when climbing stairs, it may be seen that, for example, if the left foot is placed on a certain step surface, then the right foot is placed on the step surface having the left foot. Since the body moves from the forward leaning posture to the upright posture when the right foot is put on and the movement is temporarily stopped, it is possible to climb faster when the auxiliary step (1) and the normal staircase are simultaneously used as described above.

As shown in FIG. 2, an auxiliary step (3), which is a step-like row, is provided on the left side of the normal step, and the front side of the step surface of this auxiliary step (3) is retracted to set the front and rear widths. If the width is made smaller than the width of the normal step surface of the stairs so that the step surface of the auxiliary step (3) and the step surfaces located before and after the auxiliary step (3) can be used to move up and down, the user of FIG. Although there is no confusion as embraced in the embodiment, however, since the step surface of the auxiliary step (3) and the step surfaces located in front of and behind the auxiliary step (3) are passed by both feet, the step surface of the auxiliary step (3) is It becomes necessary to widen the width on the left and right. Also,
It is often difficult to secure a certain width on the front side of the step surface of the auxiliary step (3) without unnecessarily lengthening the width in front of and behind the step surface of a normal staircase. Furthermore, the width of the entire staircase is required to be larger in order to prevent a person using a normal staircase from getting caught in the auxiliary step (3). Considering the limited space, especially in the case of stairs in a general household, the embodiment of FIG. 1 is preferred.

In the embodiment shown in FIG. 1, the stairs may be moved up and down, for example, in the dim light, people with low vision or blind people may be moved up and down, and people with a drunk condition may be moved up and down. So that there is an auxiliary stage (1) or an auxiliary stage (1)
It is desirable that the boundary between the stairs and the normal stairs be clearly colored and that a sign for the blind is provided with a protrusion on the floor.

With respect to the embodiment of FIG. 1, it is not difficult to repair the existing stairs to provide the auxiliary step (1).

Even if the auxiliary step (1) of the embodiment of FIG. 1 is provided only on one side of a normal staircase, the person who climbs up and the person who descends will meet each other. It is desirable to install it on the side or in the middle of the stairs so that both the climbing person and the descending person can use one foot each.

It is desirable that the width of the auxiliary step (1) in the embodiment of FIG. 1 is set so that a person who uses the auxiliary step (1) to move up and down and a handrail for assisting the vertical movement are not too far apart.

[0012]

According to the present invention, it is possible to easily move up and down stairs.
