Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-slip device used by being attached to stairs of buildings, ships, etc.

Conventional anti-slip devices for stairs include attaching a non-slip sheet to the nosing of the stairs, as shown in Figure 7,
As shown in the figure, a metal fitting frame 8 having a fitting groove provided on its upper surface is fixed to the step nosing, and a flexible filler 9 is fitted into the fitting groove.

However, although the anti-slip shown in Figure 7 is easy to install and does not protrude too far from the tread, so there is no risk of tripping over it, the corners are prone to wear and have no flexibility, which can lead to injury if you fall on the stairs. However, while the anti-slip shown in Fig. 8 provides flexibility to the tread with the filler 9 and protects the stair nosing due to the rigidity of the metal fitting frame 8, Since the end corner of the frame 8 is hard like the step nosing, it has the disadvantages that it is completely useless for preventing injury in the event of a fall, and that it protrudes too far from the tread surface, causing the risk of tripping.

Therefore, in order to solve such drawbacks, between the substantially flat main body fixed to the tread of the stairs and the front fixed edge fixed to the riser of the stairs, the above-mentioned A non-slip staircase for stairs is provided with a connecting portion that bulges upward from the substantially flat main body and forward from the front fixed edge, and a foam layer is integrally provided in the recess formed on the lower surface side of the connecting portion. Proposed.

However, although this kind of anti-slip for stairs, which is formed as a flat plate as a whole, can solve the various drawbacks mentioned above, it is difficult to install it to the stairs because the connecting part bulges out. Another problem is that it is difficult to position the connector, and in particular, it is extremely troublesome to accurately position the connector that is fixed to the nosing of the staircase while attaching it to the staircase.

Further, when the width of the substantially flat main body is large, the position of the rear end of the anti-slip portion on the tread side tends to be uneven, which poses a problem in construction.

The present invention solves the above-mentioned problems, and has the following features: the anti-slip does not protrude significantly from the tread, it is easy to install, the corners are hard to wear, the nosings of stairs are protected, and the corners are cushioned. It is an object of the present invention to provide a non-slip for stairs that can satisfy both the effectiveness and the anti-slip effect.

The configuration of the present invention will be explained based on the embodiments shown in the accompanying drawings.
Reference numeral 1 denotes a buffer band made of a flexible material such as soft rubber, synthetic resin, or a foam of these materials, which is placed above the tread part 5 of the stair nosing part 4 and in front of the riser part 6. Each bulges out and is fixed with adhesive or adhesive.

2 is a thin-walled flexible anti-slip sheet made of a highly abrasion-resistant material such as vinyl chloride or synthetic resin such as urethane, or rubber; and a covering sheet portion 2a that adhesively covers the surface of the buffer band 1. and a wide tread sheet part 2b which protrudes horizontally from the covering sheet part 2a toward the tread surface and has an anti-slip part 3 made up of numerous uneven parts on its upper surface. A offering sheet part 2c that projects downward on the riser side from the covering sheet part 2a is integrally formed, and the covering sheet part 2a is coated on the surface of the buffer band 1 attached in the longitudinal direction of the stair nosing part 4. At the same time, the tread sheet part 2b is extended from the buffer band 1 provided on the step nosing part 4 and attached to the tread part 5, and the offering sheet part 2c is similarly extended from the covering sheet part 2a and bonded to the riser part 6 near the step nosing part 4. It is fixed by fixing means such as glue, adhesive, and nails.

In addition, as shown in FIG. 2, the buffer strip 1 is provided with a hollow part 7 inside to further enhance the buffer effect, or as shown in FIG. Buffer strips 10 may also be provided on the surface portion 5 at appropriate intervals.

For installation on stairs, the anti-slip sheet 2 is made into a flat shape as shown in Fig. 4, and the buffer strip 1 is fixed to the nosing part 4 in advance as shown in Fig. 5. The covering sheet part 2a of the stopper sheet 2 covers the buffer band 1, and the tread sheet part 2b, which is bent and extended along the surface of the buffer band 1, is connected to the tread part 5, and the offering sheet part 2c is connected to the riser part 6. They are fixed with adhesive on each.

Further, as shown in FIG. 6, the back surface of the covering sheet portion 2a of the anti-slip sheet 2 is formed into a groove shape, and the tread sheet portion 2b of the anti-slip sheet 2 is fixed to the tread portion 5 of the stairs in advance. After that, it is also possible to fit the buffer band 1 into the back surface of the covering sheet part 2a, and then fix the offering sheet part 2c of the anti-slip sheet 2 to the riser part 6 of the stairs.

The present invention has the above-mentioned configuration, in which a flexible buffer band 1 is fixed to the nosing part 4 of a stairway, and an anti-slip sheet 2 that covers the upper surface and extends to the tread part 5 and the riser part 6 is provided. Since only the thickness of the anti-slip sheet 2 protrudes from the upper surface of the tread portion 5, there is no risk of accidentally tripping over the surface, and moreover, it absorbs some unevenness and warping of the tread portion 5 and the riser portion 6. It can be easily installed and the nosing part 4
The buffer belt 1 fixed to
The tread sheet part 2b that projects more horizontally and the offering sheet part 2c that projects downward extend longer and are fixed to the tread part 5 and the riser part 6 to wrap around the entire buffer band 1, so that the tread sheet part 2b and the offering sheet part 2c that project downward are extended and fixed to the tread part 5 and the riser part 6, respectively, and wrap around the entire buffer band 1, so that the tread sheet part 2b and the offering sheet part 2c that project downward are extended and fixed to the tread part 5 and the riser part 6, respectively, and wrap around the entire buffer band 1. It is possible to prevent the buffer band 1 and the covering sheet portion 2a from shifting or coming off due to treading pressure or pressure.

Moreover, since the buffer belt 1 and the anti-slip sheet 2 are formed separately from each other, they can be adjusted depending on the degree of elevation and frequency of use.
By changing the size of the buffer strip 1 or the length of the anti-slip sheet 2, it is possible to obtain anti-slip properties according to the intended use, and there is freedom in the installation procedure. For example, the buffer band 1 with a relatively narrow width may be first fixed to the stair nosing 4 and then the non-slip sheet 2 with a wide width may be fixed, or the tread sheet portion 2b of the non-slip sheet 2 may be fixed. It is possible to first fix the chisel to the tread part 5 of the stairs, then insert the buffer band 1 into the nosing part 4 and fix the offering sheet part 2c to the riser part 6, which prevents the buffer band 1 and slippage during installation. In addition to making it easier to position the stop sheet 2 and significantly improve its installation workability, when the buffer band 1 deteriorates or the anti-slip sheet 2 wears out, only one of them can be replaced. It is possible to save on repair costs.

Furthermore, the buffer belt 1 is fixed so as to bulge upward and forward than the tread portion 5 and the riser portion 6, and can absorb tread pressure and prevent damage to the step nosing portion 4, while also preventing accidental falls, falls, and tramples. There is no need to worry about serious injuries such as bruises or abrasions even if the stairs are damaged, and the feeling of stepping on the stairs is good when going up and down the stairs.It is also safe because it prevents your feet from slipping. Damage and wear can be prevented.

In addition, since the buffer band 1 has flexibility, it can be fixed in close contact with existing stairs where the step nosing 4 is worn out or existing non-slip surfaces.
