Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a non-slip stair for elevating stairs that is installed in buildings such as buildings, department stores, theaters, stores, etc. where jutan, carpets, etc. are laid.

(Prior Art) A conventional non-slip for a Jutan / carpet staircase is a non-slip made of soft vinyl chloride or rubber with an L-shaped cross section attached to the nose of the staircase where the Jutan / Carpet etc. are laid. It had a structure. And the anti-slip was attached by overhanging outward from the rise surface depending on the thickness of the staircase rise surface such as Joutan. For this reason, the overhang portion of the non-slip is easily bent downward due to the weight of a passerby who is involved in the anti-slip, and as a result, wrinkles are likely to occur on the jottan and the like on the riser surface.

When the weight of a passerby is removed, the slip stoppers return to their original state, but during the passage of many people over a long period of time, jutan peels off from the driving surface, wrinkles do not disappear, or the slip stopper itself. There were many obstacles such as damage to.

As described above, the conventional anti-slip has various problems in terms of durability, so that the repair cost is high and the risk of accidents for passersby is high. Further, Japanese Utility Model Laid-Open No. 55-118829 discloses a slip stopper made of a hard synthetic resin / metal having an L-shaped cross section. The non-slip material disclosed in this publication is made of a hard material, and since its vertical surface is entirely in contact with the rise surface of the stairs, the non-slip material is not deformed. When laying up to the kicking surface of the surface, there is a problem that the lower end of the non-slip and the upper end of the kicking of the rug abut against each other, and the boundary thereof spoils the aesthetics due to the protrusion and unevenness of the gap at the upper end of the kicking. Further, since the anti-slip is hard, it puts a strain on the foot, and a metallic noise or a collision noise is generated.

Further, Japanese Utility Model Laid-Open No. 55-121830 discloses a square pad material having an L-shaped cross section made of a soft material, in which a groove for accommodating the adhesive layer of the tread portion is formed on the inner horizontal surface thereof. Since the front hanging part of the square pad in this publication is in direct contact with the rise surface of the stairs, it has strength against the load from the foot, but it is possible to lay a rug up to the rise surface of the stairs as in the above publication. In this case, there is a problem in that the front sloping part and the top end of the rug rise into contact with each other, resulting in a poor aesthetic appearance of the boundary.

(Problems to be solved by the invention) The problems to be solved by the present invention are that durability is good, safety is high, construction is easy with a simple structure, and repair cost can be reduced. Moreover, the purpose of the present invention is to provide a non-slip staircase for a Juttan carpet that can beautifully finish the boundary between the non-slip and the rug even when the rug is laid on the riser surface of the stairs.

(Means for Solving the Problem) The gist of the present invention which has solved the above problem is that a small step-like protrusion is formed along the inside of a corner of an elastic long-walled material having an L-shaped cross section and the inside is perpendicular to the inside. The bending prevention part whose surface comes into contact with the riser surface of the stairs is formed integrally with or separately from the long material and is formed by being connected to the long material, and is formed below the bending prevention part of the long material. It is on a non-slip stair of the Jutan carpet floor, which has an insertion groove for inserting the upper end of the kick of the rug.

(Operation) The anti-slip used in the anti-skid of the jutan carpet staircase of the present invention has an L-shaped cross section, and is provided with a bend preventing portion that protrudes in small steps along the inside of the corner. Then, the side surface of the bending prevention part is directly attached to the upper part of the rise surface of the stairs, and a space corresponding to the thickness of the jutan etc. laid on the rise surface is provided as an insertion groove. Insert the top of the rug's kick. As a result, the boundary between the non-slip and the rug serves as a lower end line of the anti-slip and becomes a beautiful horizontal line, and the protrusion defect from the rise surface of the upper end of the kick is hidden by the front hanging portion of the anti-slip, resulting in a beautiful finish. Further, the slip stopper is in an overhanging state by the amount corresponding to the insertion groove.

When a downward force is applied to the overhang portion by the foot of a passerby, the downward bending force is changed to pressure on the kicking surface via the same bending prevention portion because there is the same bending prevention portion. Therefore, the overhang portion is not largely deformed downward. Therefore, the slip stopper is prevented from being deformed and damaged, and wrinkles or peeling of the jottan or the like on the riser surface are prevented.

In the present invention, the size of the anti-slipping anti-slip portion is adapted to the thickness of the jutan or the like laid on the stairs. The anti-slip part may be integrally molded with the anti-slip body or may be manufactured by separately molding the anti-slip part and the anti-slip part and then combining them.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of the first embodiment, FIG. 2 is a cutaway sectional view of the same portion, and FIG. 3 is a partially cutaway sectional view showing a conventional stair slip stopper.

FIG. 4 is a partially cutaway perspective view of the second embodiment.

In the first embodiment, the bending prevention portion (2) that protrudes in small steps along the inside of the keener of the long material having the L-shaped cross section (1).
The non-slip (3) provided with is attached to the nose (6) of the stairs (5) on which the jutan (4) is laid.

The anti-slip (3) used in Example 1 has an L-shaped cross section (1), and is provided with a flexure prevention portion (2) protruding in small steps. And the bending prevention part (2)
The side face (7) of the stairs (6) is attached directly to the upper part of the riser surface (8) of the stairs (6), and only the amount corresponding to the thickness of the jutan (4) laid on the riser surface (8) is enough. The slip stopper (3) is in an overhanging state, and an insertion groove (19) having the thickness of the jutan (4) is provided below the bending prevention portion (2) inside thereof.

When a downward force (10) is applied to such an overhang portion (9) by a foot of a passerby, the downward force (10) exists through the anti-flexion portion (2) because of the anti-flexion portion (2). Changes to pressure (11) on the riser surface (8) of the stairs (5).
Therefore, the overhang portion (9) is not largely deformed downward. Therefore, the slip stopper (3) is prevented from being deformed and damaged, and the jutan of the riser surface (8) is not wrinkled or peeled off.

Fig. 3 shows the conventional stair slip stopper, but since the slip stopper (12) does not have a bending prevention part, when a downward force is applied by the foot (13) of a passerby, the slip stopper (12) overhangs. The part (14) was greatly deformed downward, and there were various obstacles such as peeling of the jutan (15) on the riser surface.

The size of the anti-slip portion (2) of the slip stopper (3) in the first embodiment is adapted to the thickness of the jutan (4) or the like laid on the stairs (5). The anti-slip portion (2) of the slip stopper (3) in the first embodiment is integrally formed with the main body of the slip stopper (3).

In the second embodiment, the bending prevention portion (17) of the slip stopper (16) is molded separately from the main body of the slip stopper (16) and then combined to be manufactured and attached to the stairs (18). The operation and the like of the other parts are similar to those of the first embodiment.

Although Examples 1 and 2 both describe the non-slip of stairs laid with jutan, it can be applied as a non-slip of stairs laid with carpet or other flexible floor covering materials other than jutan. Has become. In Examples 1 and 2, the slip stoppers (3), (16)
Since the material is rubber, it does not crack or crack due to cold or deterioration like vinyl chloride. In addition, since the structure is such that no metal is used, no annoying metal noise is generated during walking, and the load on the legs and knees of the pedestrian is reduced. Furthermore, even when a pedestrian falls, the shock can be reduced.

As described above, according to the present invention, the durability of the anti-slip on the stairs is improved, the deformation and the damage are significantly reduced, the safety is improved, and the repair cost can be reduced. Further, the anti-slip of the present invention is simple, it can be assembled only by using an adhesive, no troublesome anchors and bolts are required, and special processing does not require a technique and the like, so that construction is easy.

(Effects of the Invention) The present invention provides a non-slip staircase for a jutan carpet floor that has good durability, high safety, simple structure, easy construction, and low repair cost. be able to. In addition, the stairs of the rug will be finished to look beautiful.
