Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building anti-slip device that is attached to the stairs of a building.

Stairs are the most dangerous place in a building, and it has long been recognized that some measure must be taken to ensure safety on these stairs.A concrete example of this is anti-skid structures for buildings. be.

First, as shown in Fig. 1, this anti-slip device for buildings is a metal anti-slip device A that is formed in an angular shape and is fixed so as to cover the corner from the tread surface 21 to the riser surface 22 of the stairs S. ₁ has been used for a long time, and as shown in FIG. 2, a non-slip device A ₂ has been proposed in which the portion located on the tread 21 of the stairs S is formed of hard rubber or carborundum.

However, these anti-slip devices A ₁ , A ₂
This secures a foothold by preventing abrasion and damage to the corners of the stairs S, and exerts an anti-slip function based on this foothold to prevent falls on the stairs S. Accidents such as falls on stairs S cannot be completely prevented simply by adding anti-slip functionality to the corners of stairs S, and they often occur due to missteps or trips when going up and down. , anti-slip devices as mentioned above
In the case of A ₁ and A ₂ , since the anti-slip devices A ₁ and A ₂ at the corners of the stairs S are made of rigid bodies such as metal, it is easy to cause unexpected serious injury if they rub against the surface or get bruised. Ta. Also, these anti-slip devices
Since the surfaces of A ₁ and A ₂ were not flexible, they had the disadvantage that they could no longer exhibit sufficient anti-slip properties if they got wet with water or the like.

Therefore, as shown in Fig. 3, the treads 21 of the stairs S
Metal concrete 4 with a fitting groove 42 in the part located at
1 and a soft synthetic resin filler ₄₃ that is removably fitted into the fitting groove 42 has been proposed. In this non-slip building _A2 , when the surface of the filling material 43 is worn out, only the worn filling material 43 can be easily replaced without replacing the entire non-slip material, thereby improving the anti-slip function. In addition to being able to maintain this for a long period of time, the anti-slip function of the part located on the tread 21 of the stairs S has been improved, and the feeling of stepping when going up and down has also been improved. is frequently used. however,
Even with this non-slip device A ₃ for buildings, a rigid metal part is still exposed on the front side of the corner of the stairs S, so if a person going up or down accidentally falls down, the previous non-slip device A ₁ , As with A ₂ , there was a risk of causing serious injury.

Furthermore, as shown in FIG. 4, an upward fitting groove 45 is formed at the lower end of the locking front edge 44 of the metal concrete 41 fixed to the riser surface 22 of the stairs S. A non-slip building A ₄ has been proposed in which a hanging piece 46 formed on the front end side of a filler material 43 is fitted, and the filler material 43 covers the corners of the stairs S from the tread surface 21 to the riser surface 22. There is.
This anti-slip _A4 for buildings is the tread 21 of the stairs S.
In addition to exhibiting an excellent anti-slip function, by covering the entire corner of the stairs S with the filling material 43, it is possible to absorb some impact when a person falls down. However, even in this non-slip building _A4 , the thickness of the hanging piece 46 is limited in order to prevent the filling material 43 from falling out, and furthermore, the thickness of the hanging piece 46 is limited on the back side of the hanging piece 46. Because of the location of the protrusions 47 and the like, it was not possible to sufficiently absorb the impact at this portion. One possible way to solve this problem is to increase the thickness of the filler 43, but simply increase the thickness of the filler 43, especially the part that covers the corner of the stairs S. Then, the stairs S in this part
As the protruding dimensions from the treads 21 and risers 22 of the stairs become larger, it becomes easier for people to get their feet caught when going up and down, which may cause the person going up and down to fall. I've reached my limit.

In this way, anti-slip devices installed at the corners of stairs can be used to prevent human factors such as physical and mental fatigue of climbers, fast walking or unconscious climbing, or external factors such as deficiencies in lighting or the stair structure itself. In order to prevent the various accidents that occur on stairs from becoming serious accidents such as broken bones or death, we not only have measures to prevent wear and damage to the corners of stairs and prevent them from slipping when going up and down, but also to prevent accidental falls. However, it must have the ability to absorb that shock and allow you to safely go up and down stairs.

In view of this point of view, the present invention is divided into a cushion material that exhibits cushioning properties exclusively at the corners of stairs that are subject to intensive tread pressure and impact, and a non-slip material located on the upper surface of the cushion material.
The cushion material is protected with a non-slip material so that its cushioning properties can be maintained for a long period of time, and the shock absorption at the corners of the stairs is increased, so that the anti-slip material alone can bear the burden of wear. As a result, it exhibits excellent shock absorption properties in the event of a fall accident of a person going up or down, making it highly safe and durable, especially on stairs at stations, department stores, theaters, etc. To provide a non-slip material for buildings suitable for stairs where people of a wide range of ages go up and down.
