Description

[Detailed Description of the Invention] This invention relates to a building anti-slip device that is installed to cover the corner of a staircase, and in particular, the entire anti-slip device is made of a flexible material to absorb as much impact as possible when falling. This invention relates to a non-slip device for buildings that is designed to prevent as much as possible the risk of serious injury.

Conventionally, this type of anti-slip for buildings consists of a main body fixed to the treads of the stairs, a front fixing part fixed to the riser of the stairs, and these main parts and the front fixing part connected together. Some are constructed with a connecting part that covers the corner of the stairs.

However, building anti-skids that are installed to cover the corners of stairs are always stepped on by people when going up and down the stairs, and in particular, the joints that cover the corners of the stairs are sharpened at almost right angles by tread pressure. Since the corners of the connector are pressed strongly and rubbed, the wear and damage is severe compared to other parts, and even though there is not much wear or damage on the main body or the front fixing part, only this connection part is subject to wear and damage. In some cases, the entire building anti-slip system had to be replaced with a new one.

For this reason, the durability of anti-slip structures for buildings is determined by the connections that are most susceptible to wear and damage, making it difficult to make them durable for long-term use, and it is difficult to ensure that they can withstand long-term use. Replacement of anti-slip devices for buildings, which are firmly attached to stairs using these methods, is extremely troublesome work.

In view of the above, the present invention provides a main body part located on the tread of the stairs, a front fixing part button located on the rising surface of the stairs, and a corner part of the stairs that is shaped between the main body part and the front fixing part. The connection portions located in the connection portions are made of a non-slip material integrally formed from a flexible material, and the covering body has a flexible strip plate removably attached to the top surface of the connection portions. The corner part of the staircase has a double structure by making the part thinner than the main part and the front fixing part, and gaps are formed between the connecting part and the corner part and between the covering body and the connecting part. By increasing the shock absorption of the corner of the stairs and preventing accidents on the stairs, the flexible cover is removably locked.
Only the coverings attached to the corners of the stairs, which are most frequently worn and damaged, can be replaced, providing highly safe anti-slip protection at all times.

The structure of the present invention will be explained in detail based on the embodiment shown in the attached drawings. As shown in FIG. It is a non-slip material shaped into a shape, and includes a main body part 1 fixed to the tread of the stairs, a front fixing part 2 fixed to the rising surface of the stairs, and the main body part 1 and the front fixing part 2.
The connecting part 3 is formed thinner than the main part 1 and integrally connects the front end of the main body part 1 and the rear end of the front fixing part 2, and is bent during installation to cover the corner of the stairs while maintaining a gap. A pair of engaging strips 4, 4 each having a concave shape are provided on the upper surface of the front end of the main body portion 1 and the upper surface of the rear end of the front fixing portion 2 along the longitudinal direction thereof.

B shown in FIG. 2 indicates a pair of engaging strips 4, 4 formed on the anti-slip material A on both side edges of the flexible strip plate 5 made of soft vinyl chloride resin, polyethylene resin, etc. It is a distal end envelope formed by forming bulging locking strips 6, 6 that fit together, and the distal end envelope B is relatively thin, and the distance between the pair of engaging strips 4, 4 is small. It is formed wider than the
When attached to the anti-slip material A, it is curved to cover the surface side of the connecting portion 3 while forming a gap.

It should be noted that this tip envelope B would be more effective if manufactured using a material with excellent wear resistance such as urethane resin.
It is desirable not to lose flexibility.

In order to attach the above-mentioned anti-slip material A and tip envelope B to the stairs 7, as shown in FIG. The main body part 1 and the front fixing part 2 are bent to have a substantially L-shaped cross section, and the main body part 1 and the front fixing part 2 are fixed to the treads and risers of the stairs 7 by means such as adhesive (preferably using a pressure-sensitive adhesive). Locking strips 6, 6 provided at both ends of the envelope B curved into an arched shape
is fitted onto the engagement strips 4, 4 of the anti-slip material A, or the tip envelope B is first attached to the anti-slip material A and then both are bent at the same time to be attached to the stairs 7.

The present invention has the above-mentioned configuration, and since the tip envelope B is removably attached to the surface side of the connection part 30 which is most susceptible to wear and damage with respect to the anti-slip material A, the connection part due to tread pressure etc. Abrasion and damage from the surface side of the main body 1 can be completely prevented by the tip envelope B, and the cause of peeling of the main body 1 can be prevented by severing the gap between the main body 1 and the front fixing part 2. Moreover, since the corners of the stairs 7 are most susceptible to tread pressure, only the cover B needs to be replaced, and the most dangerous corners of the stairs 7 can always be kept safe. The durability of the anti-slip material A can be improved and it is economical.

Furthermore, the connecting part 3 is formed into a thin wall and is integrated with the main body part 1'J=- and the front fixing part 2, so that the staircase 7 together with the button covering body B can be attached.
The corners of the button and the staircase 7 have a double structure, and gaps are formed between the corner of the connection part 3 and the staircase 7, and between the connection part 3 and the envelope B. In addition to further improving the impact absorption effect at the corners of the 7, the feeling when stepping on it is also improved.

Furthermore, since the anti-slip material A and the tip enveloping body B are formed separately, they can be manufactured in various colors. By selecting a color similar to that of the stairs 70, and selecting a material with a color different from that of the stairs 7 or a material coated with luminous paint for the distal end encapsulation B, the stairs 70
It is possible to improve the identification of the tip envelope B located at the corner, and to adopt various color combinations according to the preference of the construction owner, which is excellent in terms of safety and design effect. Can provide anti-slip protection for buildings.

In addition, the anti-slip material A and the envelope B are separate bodies, and only the connecting part 3 of the anti-slip material A is made of a material with high abrasion resistance and shock absorption, so that the main body part 1 and the front fixing part are made of a material with high wear resistance and shock absorption. There is no need for complicated processes such as using a material different from the second material to form a certain shape, and it is sufficient to mold a single material using a relatively common technique, and the manufacturing cost can be reduced.

In addition, although the above description has been made of the non-slip material A and the tip envelope B being made into a substantially flat shape, in order to eliminate the bending work during installation, the non-slip material A may be made into a substantially L-shaped cross section. Alternatively, the tip envelope B may be formed to have a substantially arcuate cross section, each wrapped in a tape shape, and when attached, the tape may be unrolled and returned to its original shape due to the flexibility of the material.
