2. Description of the Related Art Conventionally, stairs have been used for connecting upper and lower floors of general houses and various public facilities. The dimensions of the rise of the stairs, the depth of the tread, the width and the like are specifically defined by the Building Standards Law. This is a reference value set to satisfy the function according to the type of the building, and does not specify the convenience of a normal stair user, that is, the ease of going up and down. For this reason, in public facilities and ordinary houses widely used by elderly people and children, there are various staircases in which the steps are too large and it is difficult for the elderly to ascend and descend.

[0003] For this reason, recently, a slope (ramp) is provided at an appropriate place in the facility, and a rise height is reduced,
Many public facilities, such as stairs with gentle slopes, have been constructed. In addition, various types of residential elevators and simple lifts using stair spaces have been developed and commercialized from the viewpoint of considering the convenience of elderly people to go up and down stairs.

[0004]

However, in the case of a design incorporating a ramp or a stairway with a gentle slope as described above,

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a modified staircase structure according to the present invention.
FIG. 1 shows the basic structure of the irregular staircase structure.
FIG. 1 shows an existing staircase portion 10 having the conventional structure dimensions.
And a step 20 formed over a certain width on the side of the wall of the occupied portion where the existing stairs 10 are provided. In the step portion 20, the depth L and the rise height H of the tread surface 22 are set to be equal to the depth L and the rise height H of the tread surface 12 of the existing stair portion 10, and the height and the depth direction of each tread surface 22 are set in the existing staircase. The portions 10 are arranged at positions shifted by １ ／ with respect to the tread surface height and the depth, respectively. As described in each of the following embodiments, the stepped portion is provided with a through hole.
Easy by adding simple modifications to the existing stairs
Can be formed.

A part of the stair structure has a stepped portion 2 as described above.
0 can be easily provided, so that when the user M shown by the imaginary line climbs the irregular stairs, the tread 22 of the step 20 and the tread 12 of the existing stair 10 are alternately arranged. By stepping up, the stride length of one step when moving forward and the rising height which affects the bending and extension of the knee can be reduced to の of the conventional staircase structure. As a result, the burden on the elderly, who has a reduced ability to flex and extend the knee, is reduced, especially when the person lifts and lowers. By providing such a stepped portion 20, a tread portion corresponding to a half step from the existing staircase portion 10 is widened at the exit and the ascent of the stairs. In addition, there is also a secondary advantage that the first step of descent can be easily performed, and the fear of the elderly when walking down the stairs can be removed.

The step 20 is provided on the side of the wall where the handrail 1 is arranged as shown in FIG. 1, so that the elderly, who is a user, can easily perform the irregular stairs while holding on to the handrail 1. You can go up and down. Therefore, the range b of the step portion 20 is set to a width to a position where the center line position of the body and the step boundary of the stairs coincide when a relatively small person such as an elderly person is gripped by the handrail 1. Is preferred. When the width of the step portion 20 is set in this manner, the width of the existing staircase portion 10 can be made sufficiently large, and a user who does not hinder the ascending and descending at a normal rising height can move up and down the existing staircase portion 10 as usual.

The modified staircase structure according to the embodiment shown below is
Usually used as a standard riser stair,
In a house or a public facility where the elderly people visit and use the stairs, or when the house built during prime work continues to live even if they become older, the above-mentioned step 20 may be used as necessary. Can be easily formed on a part of the existing staircase portion 10.

(First Embodiment) FIGS. 2 to 3 show a first embodiment in which a slidable step portion incorporated in a part of the existing staircase portion 10 is incorporated.
This will be described with reference to FIG. As shown in FIG. 2, instead of the stepped portion 20 shown in FIG. 1, between the existing staircase portion 10 and the wall, the tread surface 2 which has the same surface as the existing staircase portion 10 in appearance.
2 and a slide step portion having a rise height H are formed. The slide step section is divided into an upper slide step section 25 and a lower slide step section 26 as shown in FIG.

When the stair portion shown in FIG. 2 is used as the above-mentioned alternate staircase, the upper slide step portion 25 is first pushed in as shown by the arrow, and the inside of the stair is reduced by half of the depth of the tread. And a stepped lower portion 20A is formed at an intermediate position between the upper and lower existing stair portions 10. 1 so that it matches the position of the lower step 20A.
The lower slide step portion 26 at the upper position of the step is advanced so as to be pulled out of the inside of the stair by half of the depth of the tread surface, and is overlapped on the lower step portion 20A to form the upper step portion 20B. In this way, the slide steps 25 of each stage are retracted.
Then, the slide step portion 26 is advanced to easily form an alternately shaped tread having a step portion 20 (20A, 20B) as shown in FIG. 3 over the entire step portion.

At this time, as shown in FIG. 4, it is also possible to form a storage drawer in each stage in which the slide step portion is formed as a hollow box and the inside of which the tread surface 22 is a lid 27 is a storage space. The slide step section 25 has a slide
The amount of retreat (pressing amount) at the time of
Reference numeral 6 is provided with a stopper and a position holding mechanism for defining a forward movement amount (drawing amount) at the time of sliding . Thereby, in each step, the position can be reliably secured by sliding the slide step portions 25 and 26 to the stopper position. As the stopper, a dowel having a predetermined fitting portion may be formed on each sliding surface,
A stopper mechanism may be incorporated in a slide rail (not shown) for sliding the slide step portions 25 and 26.

Second Embodiment A modified staircase structure using a staircase block in which an existing staircase structure is used as it is to realize a modified staircase structure will be described with reference to FIGS. The staircase block 30 shown in FIG. 5 has a structure installed on each tread 12 of the existing stairs, and the dimensions of each part are set according to the dimensions of the existing stairs. The block width is set to be equal to the existing step width B, and the height of the block 30A constituting the existing step portion 10 is set to be equal to the rise height H, and the depth is set to be equal to 1/2 of the tread surface L. This block 30A
3 that constitutes the step 20 formed integrally with the block 3
0B is set so that the height is equal to 1/2 of the rise height H and the depth is equal to the tread surface L. The width b of the block 30B constituting the step portion 20 is set to be equal to that of the handrail 1 as described above.
Can be set to an appropriate width based on the positional relationship with.

As shown in FIG. 6, the stair block 30 having the above-described structure is sequentially installed and fixed to the existing stairs 10 to form an alternately shaped step stair having a step 20 similar to that shown in FIG. Can be configured. Note that the lowermost staircase block 30 may be placed and fixed on the floor at the stairway entrance. By incorporating the stair block 30 into the existing stairs 10, the tread of the existing stair portion 10 is constituted by the tread 12 of the existing stair 10 and the tread 31 of the block 30A, but the tread 31 is made of the same material as the existing portion. Alternatively, a material having an anti-slip effect may be used. Further, since the staircase block 30 is arranged at each step, it is preferable to provide a fixing tool (not shown) that is securely fixed at each step. For example, it is preferable to form an uneven portion that can be fitted between the existing tread surface and the lower surface of the staircase block 30 and fix the staircase block 30 so that the staircase block 30 does not accidentally move. It is also preferable to use a vinyl acetate adhesive in the case of a wooden stair and a mortar or an epoxy resin adhesive in the case of a concrete stair, in addition to a method of mechanically fixing a fixture or the like.

FIG. 7 shows an example in which a modification of the staircase block is sequentially installed and fixed to the existing staircase 10 to form an alternately shaped staircase having a stepped portion 20 similar to that shown in FIG. Things. In the present modification, a part of the existing staircase 10 is moved from the front position of the stairs to approximately 1/2 of the depth length L of the tread surface 12 and approximately 1/2 of the kick height H from the tread surface 12 over the range b forming the step portion 20. Of the existing stairs 10 while cutting out only the stair cut portion 32 which forms a substantially rectangular parallelepiped.
The stepped portion 20 is formed and fixed on the tread surface 12 such that the stair cut portion 32 and the stairs ascending and descending directions are alternately positioned. At this time, the lower part 20A of the step part is the stepped cut part 32.
Is formed of the remaining portion of the existing stairs 10 from which the stairs are removed, and the upper step portion 20 </ b> B is formed of a stair block 33. Further, in order to fix the stair block 33 on the tread surface 12 of the ready-made stairs 10, the above-mentioned fixing means for fixing the stair block 30 can be applied. In this modification, an operation of cutting a predetermined portion of the ready-made staircase 10 into a substantially rectangular parallelepiped shape occurs. However, the cutting operation can be easily performed by designing the staircase structure 10 in advance to a structure in consideration of the cut portion. .

[0023]

As is apparent from the above description, according to the present invention , a relatively inexpensive structure is added to the existing stairs and simple operations are performed to reduce the existing stairs to the elderly or the body.
This has the effect that the disabled can be remodeled into stairs that can be safely moved up and down.
