DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display staircase for providing information for designing and selecting a staircase for a person who is going to build a house at a house exhibition hall or the like .

[0002]

2. Description of the Related Art Standard stairs in a conventional house are designed by a house maker, and a client who builds the house gives an opinion on the shape of the stairs, the height of a handrail, and the like. It was impossible to design a staircase of your choice.

[0003]

Considering the future population structure of Japan, the ratio of elderly people will gradually increase. And the number of homes where only elderly couples live will increase. Therefore, it is necessary to consider the assumption that a house lives for a lifetime. In this way, when considering a house that will last a lifetime, it is necessary to design a house that is easy to live in when the elderly become elderly. Stairs are particularly problematic when elderly people live. If the stairs are not sufficiently sloped or treaded, the incidence of elderly people falling off the stairs, breaking, and becoming bedridden increases.

[0004] The present invention aims to make the stairs, which are the most problematic in houses where the elderly live, less likely to cause an accident.
It has the necessary functions. In addition, the size of the tread and kick-up, which constitute the gradient of the stairs, should be large enough, and the tread should be wide enough for the thumb ball of the toe to rest on. However, this leads to an improvement in the stability of the elderly when going up and down. In order to obtain a tread surface on which the thumb ball can be placed, the width of the tread plate and the width of the projecting portion of the step are optimized.

[0005]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. In claim 1, the step board 15
And the riser 7 and the tread protruding beyond the riser 7
A stair is constituted by 15 step portions 6, and from the width of the tread plate 15
The width obtained by subtracting the step 6 is defined as the tread effective width a, and the tread plate 15
The height between the tread and the tread plate 15 is referred to as a kick-up b, and the tread surface is present.
One staircase with different sizes of effect width a and kick-up b
Are continuously arranged on the stairs . According to a second aspect, in the gradient comparing step according to the first aspect, the step
The handrail wall on one side is a transparent plate .

Next, an embodiment of the present invention will be described. FIG. 1 is an overhead view showing the overall configuration of a staircase comparison staircase with a lifting handrail, FIG. 2 is an enlarged perspective view showing an electric lifting handrail part, FIG. 3 is an enlarged view of the same electric lifting handrail part, and FIG. FIG. 5 is a perspective view showing an elevating mechanism of the slide 1, and FIG.
FIG. 6 is a drawing showing the configuration of the life staircase A in an optimal state, FIG. 7 is a drawing showing the configuration of the limit staircase B of the Building Standard Law, and FIG. 8 is a standard pillar of a current house. It is a figure showing composition of standard 910 module stairs C calculated backward from 910 cm which is a position pitch.

In order to improve the stability of climbing up and down stairs,
The handrails that the elderly can have play an important role. And when you are young, the height of the handrail does not matter, but when the hips are bent and inconvenience occurs, the height of the handrail also becomes a problem, so this handrail is adjusted up and down electrically. It was made possible. FIG. 1 shows the configuration of a staircase with a lifting handrail provided with an electric lifting handrail. The staircase with a handrail is installed at a place such as a house exhibition hall or an exhibition hall of each facility for design study. It is a device that guides you to the front of the stairs and derives potential information about what stairs you want. In the case of prospective house builders, it is not possible to submit the figures and images clearly to the designer, even if they are thinking of potentially building such a house. , See a lot of existing houses, walk around the houses of each company at the house exhibition hall,
Most of them find some design guidelines.

[0008] However, what is usually most emphasized by the prospective construction person is the floor plan, the arrangement of the entrance, the garden, the doors and the windows, the floor and the curtain, etc., and the configuration of the stairs is overlooked. However, if you live in that home for the rest of your life, stairs will have the greatest impact as you become older, and the configuration of these steps is likely to be a major factor in determining the life of the elderly. is there. The people who are planning to build a house will clearly understand the way the stairs should be in this age.
I try to make use of it in design.

In FIG. 1, based on such a purpose,
Various devices are arranged on one stair. On one wall side, an electric handrail 1 having an electric part embedded in the wall is arranged. And the handrail wall 9 of the other wall is formed of a transparent plate so that an elderly person or a toddler can observe or visualize the way of going up and down the stairs. However, if the transparent plate alone is used, there is a possibility that the transparent handrail wall may be pushed down and fall.
Has reinforced strength.

The electric handrail 1 constitutes a lifetime residential stair A at the lowest position. Above the lifetime residential staircase A, the average staircase indexed from the current standard pillar position pitch of 910 millimeters is shown as 910 module staircase C. In addition, on the extension of the 910 module stairs C, at the opposite slope, the limit stairs B of the Building Standard Law
Is configured.

FIGS. 2, 3 and 4 show the configuration of the electric handrail 1 provided on one wall side. The configuration for driving the electric handrail 1 is configured as shown in FIG. That is, the electric handrail 1 is supported by the support rod 4, and the support rod 4 can move up and down in the elongate hole 2 provided in the wall. The base of the support rod 4 is fixed to the female screw 5. The female screw 5 is screwed onto the male screw rod 3, and the male screw rod 3 is connected to a drive motor 10 having a reduction gear 11.
Is rotated forward and reverse. An elevating operation switch for rotating the drive motor 10 forward and backward is separately provided, and by operating this switch, the position of the electric handrail 1 is changed up and down. A plurality of sets of the drive motor 10 and the male screw 3 are arranged at upper and lower positions.

As shown in FIG. 2 and FIG.
The height scale 7 is clearly indicated on the side so that the height of the electric handrail 1 can be specifically grasped as a numerical value. While watching this, the height of the handrail is determined on the assumption that the elderly will be elderly. If the height of the handrail is determined based on the present condition when the body is healthy, it will be an inadequate housing for a lifetime. Also, since the life of the elderly changes daily, in order to be able to change the height of the handrail according to the state of this life,
It is most effective that the electric handrail 1 is provided. However, the cost is slightly higher.

As described above, in the handrail supporting portion provided on the wall of the stairs, a long hole perpendicular to the wall of the stairs is opened,
Since the handrail support moves up and down in the long hole, the elderly can gradually move up and down the electric handrail on the stairs according to the degree of obstacle. As a result, even a disabled person can go up and down to the second floor. In the handrail support provided on the wall of the stairs, an elongated hole perpendicular to the wall of the stair is opened, and the support of the handrail moves up and down in the elongated hole. Since the handrail wall on one side of the handrail is made of a transparent plate, it is possible to record from the side as a video record the state in which the handicapped person goes up and down with the electric handrail up and down, and goes up and down the stairs of the handicapped person It became possible to reproduce the state of, and use it as a basis for future life-long housing design.

FIGS. 5 and 6 disclose the configuration of the life-long residential staircase A. FIG. In the life staircase A,
The tread effective width a and the kick-up b are safe even if the elderly person goes up and down. In this configuration, a step 6 protrudes from the step board 15 beyond the riser 7. The width of the tread 15 including the step 6 is 23 cm,
Among them, the length of the step portion 6 which is a protruding portion from the riser plate 7 is set to 1 cm. As a result, the width of the tread effective width a is 22 cm. The kick-up b is 19.85
cm.

With this configuration, the probability that the part of the foot of the foot up to the ball of the thumb is placed on the tread plate 15 is increased, and the elderly can climb up and down in a stable state. In other words, whether or not the thumb ball portion of the foot is placed on the tread effective width a constitutes the boundary line between slippery and slippery. In the lifetime housing stairs A shown in FIGS. 5 and 6, a sufficient tread effective width a and a kick-up b are taken so that the thumb ball of the foot rides on the tread effective width a. It is also assumed that the elderly can climb up and down.

FIG. 7 shows the limit staircase B of the Building Standards Law. In the Building Standards Law, a certain standard of the width is defined for the stairs, and the stairs are formed on the limit side of the wide standard in the Building Standard Law Limit Stairs B. In this case, the width of the step board 15 is 15 cm.
As described above, since the portion of the step portion 6 protruding from the riser plate 7 is specified to be 7 cm, the actual effective width t of the tread surface is about 7.5 cm.
Also, the kick-up b is specified to be 23 cm, which is very high for an elderly person and is unstable.

In FIG. 8, the pitch 9 of the current pillar position is shown.
At 10 mm, a standard 910 module staircase C is shown. In this case, the step board 15
Is 18.2 cm, the step 6 is 3.8 cm, and the tread effective width a is 14.4 cm. Also, the rise b is as high as 20.2 cm. As described above, the stairs shown in FIGS. 7 and 8 have a high kick-up b and a small effective width a of the tread surface, so that the foot is not placed up to the thumb ball, so that the foot slips on the stairs. Occurs.

[0018]

As described above, the present invention has the following advantages. As described in claim 1, a plurality of stairs having different sizes of the tread effective width a and the kick-up b are successively arranged on one stair, so that a person who intends to construct a house from now on can check the quality of the stairs. As a personal experience, it became possible to understand the importance of handrails.

According to a second aspect of the present invention, a plurality of steps having different sizes of the tread effective width a and the kick-up b are successively arranged on one step, and the handrail wall on one side of the step is formed of a transparent plate. As a result, it was possible to take a picture of an elderly person climbing up and down various stairs as a video record such as a video, and to examine this in detail. This made it possible to incorporate stairs and handrails that are optimal for the elderly when designing the house.
