Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-slip device installed on stairs of buildings, etc.

Traditionally, stairs, especially those made of concrete or terrazzo, were protected by L-shaped plates made of metal such as steel or brass to prevent wear and tear at the corners (Figure 15). ).

However, when this L-shaped board is installed, although it protects the corners of the stairs, the surface on the tread side is smooth, making it slippery and dangerous for people going up and down. Boards came to be used that had various concave and convex grooves continuous in the longitudinal direction on the top surface to prevent slipping. This was the first thing that changed from a protective plate to a stair anti-slip device (Figure 16). After that, the development of various materials led to the development of anti-slip materials for stairs, including one in which an inverted T-shaped metal frame was integrally molded with anti-slip material made of hard rubber material (Fig. 17), In order to maintain the anti-slip effect and to allow partial replacement when the top surface is worn out, a fitting groove is formed in the frame of the metal rod so that the metal rod can be attached to and removed from the filling material made of European synthetic resin. Insets (Fig. 18) were devised and came into use.

In this way, there has been a shift from protecting the corners of stairs to anti-slip products aimed at preventing stairs from slipping, and various improvements have been made, but mainly only the anti-slip effect on the foundation side has been emphasized. The corners of the stair cleats, which are the most likely to collide with when falling down the stairs, have metal frames and bases made of hard materials that protrude and are exposed, similar to the protective plate mentioned above. It was not possible to protect the stairs from collisions caused by the stairs, and safety on the stairs had not yet been achieved.

Another drawback of conventional anti-slip materials is the complexity of repair work.

Wear on stair anti-slip surfaces occurs fastest on the top non-slip part that receives tread pressure when going up and down, followed by the corner parts, but this wear does not occur uniformly on the non-slip surface, but relatively on the handrail side. concentrated near the
This tendency is particularly noticeable on stairs that are frequently climbed and descended, such as those in stations and department stores. Therefore, in a non-slip device such as that shown in Fig. 18, in which the filling material is removably inserted into the groove of the metal bar, the filling material must be replaced periodically or depending on the state of wear. was unable to maintain its functionality. However, as mentioned above, with this type of anti-slip, it is difficult to accurately judge when to replace the anti-slip because it wears out locally, and it is difficult to accurately judge when to replace it. Even if you replace
In many cases, the engaging portion of the metal frame was reduced and the filler material came off.

In addition, the stair anti-slip shown in Figure 17 cannot be partially replaced when its surface is worn out, so the entire non-slip had to be removed and replaced with a new product. It is firmly fixed with anchors or adhesives to prevent it from wobbling or coming off in the middle, so when replacing the entire non-slip part, the stairs near the non-slip part must be destroyed to create a mounting surface for the non-slip part. This results in large-scale but complicated work such as repairing stairs, and worn-out anti-slips are often left as they are.Similar to protection plates using L-shaped plates, they are simply used to protect stairs that have lost their anti-slip effect. I have often seen cases in which anti-slip devices have been installed that are only worthy of this.

In addition, for wooden stairs, etc., the flat plate part of the non-slip plate is fixed with fasteners such as wood screws or nails, but the load on the non-slip may cause wear of the fasteners exposed on the surface, etc. This has disadvantages in that the foot loosens and causes rattling, and the head of the fastener protrudes toward the surface and drags on the footwear, causing falls and spills when going up and down.

The present invention was made in view of the above-mentioned anti-slip problem, and the first purpose is to protect the stairs and to be able to always attach and fix the anti-slip in a stable state.

The second purpose is to have an anti-slip effect and absorb the impact of falls, preventing injuries and maintaining safety. The third purpose is to be able to maintain a certain anti-slip effect and cushioning effect by replacing parts as appropriate depending on the degree of friction, and to protect the stairs by being fixed to the base of the stairs, and to protect the stairs. There is a roughly L-shaped fixed board with rigidity to form a non-slip mounting surface at the corner, and it is fixed to the top surface of this fixed board, and the flexibility of the fleshy part prevents stepping on it due to the load when going up and down. A soft anti-slip body with a slightly thick wall that absorbs pressure and has a cushioning effect at the tip of the anti-slip and a separation effect from the floor finishing material at the rear end, and almost the entire top surface of this anti-slip body. To provide a non-slip for stairs formed by laminating thin anti-slip strips which are detachably attached and can always maintain a stable anti-slip effect. The structure of the present invention will be explained based on the embodiments of the accompanying drawings. As shown in FIGS. 1 and 2, the anti-slip according to the present invention is made of a rigid material that is fixed to the corner of the stairs. A substantially L-shaped fixed substrate A to be manufactured, a flexible and slightly thick anti-slip main body B fixed to the upper surface of the fixed substrate A, and this anti-slip main body B
It consists of a non-slip strip C that is removably attached to the top surface of the holder.

The fixed board A fixed to the green corner of the stairs is made of stainless steel.
It is made of a highly rigid material such as a metal such as aluminum or brass or a hard synthetic resin, and a locking front line 2 that covers the riser surface of the stairs is vertically provided at the front end of the elongated horizontal piece 1 at a substantially right angle. The horizontal piece 1 has an abbreviated shape in cross section, and on the rear end side of the horizontal piece 1 there is a rising edge that partitions the space from the floor finishing material 8 attached to the treads of the stairs and forms a concave engaging part 24 on the inner wall thereof. A greenery 3 is erected and fixed to the stairs with appropriate anchors 4 fixed to the lower surface of the horizontal piece 1.

Note that, as shown in FIG. 2, the fixed board A is also used as a fixed tree to form a recessed part 6 for attaching a non-slip member to the corner part when stairs are manufactured in advance. To prevent particulate matter such as mortar from adhering to the upper surface of the fixed substrate A or causing damage, as shown in FIG. 3, a foam or similar protective material 7 is temporarily attached and removed at the time of construction. is desirable. Also, when fixing the anti-slip after finishing the stairs, fix the horizontal piece 1 with adhesive, etc., and make the rising edge 3 a very slight rise of about 8 of floor finishing material such as tiles (not shown). figure). In addition, as shown in FIG. 2, the fixed substrate A is not only made in advance into an L-shape by extrusion molding, but also has bending guides such as notches and stripes in a plate made of aluminum or the like that is relatively easy to bend. The strips are provided near the front and rear ends, and during construction, from this bending guide strip, one side is bent downwards and the other side is bent upwards, and the front green 2 and rising green 3
It is also possible to use a material formed by forming a.

The anti-slip body B provided on the upper surface of the fixed substrate A is made of a synthetic resin material such as soft vinyl chloride or a flexible material such as rubber. A hollow part 26 is provided inside, and a buffer band 11 is formed in a protruding manner on the upper side and the front side, and the rear end side is engaged with a concave engaging part 24 formed on the inner wall of the rising edge 3. A swollen locking portion 25 is provided integrally with each other, and a medium-wide iron groove 5 is formed in the longitudinal direction on the entire surface of the road surface.

It is desirable that the buffer band 11 be formed in a protruding shape upwardly from the line ff in FIG. 1 and in front of the line h-h in FIG. (not shown).

In addition, 12 is a recess provided on the lower surface of the flat base 10, which improves the adhesion with the fixed substrate A, and 13
This is a hollow ridge provided at the center of the flat base 10, and is intended to provide an even more cushioning effect to the flat base.

As shown in FIG. 4, this anti-slip main body B has an awning part 14 integrally provided below the buffer band 11, and a fixed base plate A.
The front surface of the locking front edge 2 of the fixed board A
In order to further improve the adhesion between the
In order to further prevent wear of the anti-slip body B, it is desirable to use a material with excellent wear resistance, such as urethane, at least on the front end side buffer band 11 or the rear end side.

This anti-slip main body B has the buffer band 11 on the front end side, and the bulging locking part 25 on the rear end side on the rising edge 3.
The flat base 10 is fixed to the upper surface of the horizontal piece 1 by engaging with the concave engaging portion 24 of the flat base 10 .

When installing this, in the case of stairs where there is not much going up and down and the buffer strip 11 at the front end will be used for a long period of time, it is possible to attach it with adhesive, etc.; When used on stairs with very high levels of friction, the anti-slip main body B may be fastened to the fixed base plate A with screws (not shown), or a locking portion 15 may be provided in advance on the fixed base plate A and the buffer band 11 at the front end may be tightened. It is desirable to be able to replace the anti-slip body B when it becomes worn out or damaged (Fig. 7). In addition, the flat base 10 of the anti-slip main body B
If a part of the anti-slip material is made of a relatively hard material such as semi-hard material, remove the caps 16 on both ends of the non-slip material to prevent the non-slip material from slipping, as shown in FIGS. 8 and 9. The main body B is laterally pulled out from the fixed base plate A, and a new anti-slip main body B is similarly pushed in from the side and attached, and the cap 16 is again covered. The slightly thin anti-slip strip C attached to the upper surface of the anti-slip main body B has a number of anti-slip parts 18...18 provided on the upper surface of the flat main plate 17. Anti-slip body B
The iron fitting is removably engaged in the iron fitting groove 5 formed on the upper surface of the holder.

The present invention has the above-mentioned configuration, and is fixed to a corner of a staircase, and has a substantially L-shaped cross section and has a rising edge having a grooved engaging portion on the inner wall on the rear edge side. A buffer band having a hollow portion formed therein for absorbing tread pressure due to the load during lifting and lowering is formed on the top surface in a protruding shape at least on the tip side, and a swollen locking portion that is engaged with the concave engaging portion on the rear edge side. A flexible anti-slip body is provided, and a thin anti-slip strip with a non-slip part is removably locked in a lattice groove formed on the entire surface of the anti-slip body. The corner portion of the stair base is protected by the rigid fixed substrate, and the lower surface of the flexible anti-slip body is always supported in a stable state on the fixed substrate. A rising green is provided in the partition between the surface part and the floor finishing material, and a swollen locking part formed in the back green of the anti-slip body is engaged with a concave engaging part formed on the inner wall of the raised green. This prevents the rear end of the anti-slip body from lifting up due to tread pressure or sliding horizontally and peeling off, and also protects the tip of finishing materials such as tiles, and prevents the rear end of the anti-slip body from peeling off due to tread pressure. There will be no gaps between the two. Furthermore, a fixed base plate having rigidity, a flexible slightly thick anti-slip body fixed to the upper surface of the fixed base plate, and a medium-wide iron groove formed on the entire road surface of this non-slip body. It is formed separately from a thin anti-slip strip that is removably locked to the steel plate, so if you use the anti-slip strip alone or together with the non-slip main body, the wear and tear of the non-slip strip can be reduced. Alternatively, it is possible to perform partial repairs depending on the state of wear, and this can be done quickly and easily, and the stairs will not be damaged during such repairs.

In addition, the anti-slip body has a flexible material characteristic and a buffer band on the tip side that is hollow inside and protrudes at least upwards, so that it can withstand the load when going up and down or the most impact when falling. It is installed in corners that are susceptible to damage, and absorbs the impact of falling accidents that occur when going up and down stairs, so you can always go up and down stairs safely.
