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 been recognized for a long time that some kind of measure must be taken to ensure safety on these stairs, and a concrete example of this is anti-skid structures for buildings. .

First, as shown in Fig. 1, this anti-slip for buildings is a metal anti-slip that is formed in an angular shape and is fixed to cover the corner of the staircase S from the tread surface _S1 to the riser surface _S2 . Tool A ₁ has been used for a long time, and as shown in Figure 2,
A non-slip tool _A2 has been proposed in which the portion located on the tread surface _S1 is made of hard rubber or carborundum.

However, these anti-slip devices A ₁ , A ₂
This method secures a foothold by preventing abrasion and damage to the corners of the stairs S, and prevents falls on the stairs S by exerting an anti-slip function based on this foothold. Accidents such as falls on stairs S cannot be completely prevented simply by adding anti-slip functionality to the corners of stairs S, and often occur due to missteps or tripping when going up and down. Anti-slip device A ₁ as described above,
In the case of A ₂ , the anti-slip device A ₁ at the corner of the stairs S,
Since A ₂ is a rigid body such as metal, it is easy to cause unexpected serious injury if the surface is rubbed or bruised. In addition, these anti-slip tools A ₁ ,
Since the surface of _A2 was not flexible, it had the disadvantage that it could no longer provide sufficient anti-slip properties if it got wet with water.

Therefore, as shown in Fig. 3, the tread S ₁ of the staircase S
Gold concrete 5 with a fitting groove 51 in a portion located at
2 and a soft synthetic resin filler ₅₃ that is removably fitted into the fitting groove 51 has been proposed. When the surface of the filling material 53 wears out, the anti-slip A ₃ for buildings does not require replacing the entire non-slip material.
3 can be easily replaced, which not only maintains the anti-slip function over a long period of time, but also improves the anti-slip function of the part located on the tread _S1 of the stairs S. Today, it is frequently used for stairs in buildings because of its improved tread feel. However, even with this anti-slip device A ₃ for buildings, a rigid metal part is still exposed on the front side of the corner of the stairs S, and if a person going up or down accidentally falls down, the anti-slip device A ₁ , A ₂ , there was a risk of causing serious injury.

Further, as shown in FIG. 4, an upward fitting groove 55 is formed at the lower end of the locking front edge 54 of the metal concrete 52 fixed to the riser surface _S2 of the stairs S. A hanging piece 56 formed on the front end side of the filler 53 is fitted into the filler 55, and the tread of the stairs S is fitted with this filler 53.
A non-slip building _A4 has been proposed that covers the corner from _S1 to the riser surface _S2 . This non-slip A ₄ for buildings not only exhibits an excellent anti-slip function on the tread S ₁ of the stairs S, but also covers the entire corner of the stairs S with a filler material 53 to absorb some impact when a person falls down. Can be absorbed.

However, even in this anti-slip building _A4 , the thickness of the hanging piece 56 is limited in order to prevent the filling material 53 from falling out, and furthermore, the thickness of the hanging piece 56 is limited on the back side of the hanging piece 56. protrusion 5
Because the 7th grade was located in this area, it was not possible to sufficiently absorb the impact. One possible way to solve this problem is to increase the thickness of the filler 53, but simply increase the thickness of the filler 53, especially the part that covers the corner of the stairs S. As a result, the protrusion of this part of the stairs S from the tread _S1 and the riser surface _S2 becomes larger, which makes it easier for people to get their feet caught when going up and down, causing the person going up and down to fall. There is a limit to the improvement of shock absorption at the corners, and since the filler 53 is made of a single material, the suitability of the material required for the tread and the suitability required for the corners are different. The drawback was that one of them had to be sacrificed.

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 turning into serious accidents such as broken bones or death, we not only have a function that prevents wear and damage on the corners of stairs and prevents them from slipping when going up and down, but also prevents them from falling accidentally. It must have the ability to absorb the impact and allow safe movement up and down the stairs.

In view of this point of view, the present invention provides an anti-slip function by the anti-slip part from the corner of the staircase to the tread, and also provides a front part of the anti-slip part attached to the front filling body and the upper surface thereof. Therefore, the safety of the stairs is significantly improved by increasing shock absorption near the corners of the stairs, and the front filling body and the rear filling body, which are manufactured separately, are used in the deep grooves and shallow grooves of the frame. By fitting and locking the anti-slip material to the frame body, the anti-slip material can be firmly attached to the frame, and a material with high cushioning properties can be selected for the front filling body, and a material suitable for the tread can be selected for the rear filling body. In this way, we provide a non-slip structure for buildings that allows the use of the most suitable material for that part.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In FIG. 5, a non-slip structure for buildings according to an embodiment of the present invention is shown.

This non-slip device for buildings is fixed to the tread _S1 of a staircase S, and has a horizontal mounting piece 3 that forms a shallow groove 2 on the top surface thereof, and a deep groove 4 that extends to the front end of the horizontal mounting piece 3. , a frame body 1 consisting of a vertical mounting piece 5 fixed to the riser surface _S2 of the stairs S, and this frame body 1
The rear filling body 6 is fitted and locked in the shallow groove 2 of the horizontal mounting piece 3, and the rear filling body 6 is formed on the front side of the rear filling body 6 and is fitted and locked in the deep groove 4 of the vertical mounting piece 5. The front filling body 7 has a front filling body 7, and a non-slip member 9 includes a substantially flat anti-slip portion 8 which is attached to the upper surface of the front and rear filling bodies 6, 7.

The frame body 1 is made of a rigid material such as a metal such as aluminum or brass or a hard synthetic resin, and the horizontal mounting piece 3 is provided with hook-shaped locking protrusions 10a and 10b at its front and rear ends. The locking protrusion 10a on the front end side receives the front side edge 11a of the rear filling body 6 to prevent it from shifting forward, and the locking protrusion 10b on the rear end side receives the front side edge 11a of the rear filling body 6 to prevent it from shifting forward. The rear filler 6 is removably fitted into the shallow groove 2 formed in the horizontal mounting piece 3 by engaging the side edges 11b.

At the front end of the horizontal mounting piece 3, the vertical mounting piece 5 extending downward has a bottom wall 12 projecting laterally from its lower end, and a locking protrusion projecting upward at the tip of the bottom wall 12. The deep groove part 4 is formed by the strip 13.
are formed to removably fit and lock the front filling body 7.

The locking protrusion 13 has an inward protrusion 14 projecting on the inner surface of its upper end, and is fitted into a groove 15 formed on the side surface of the front filling body 7 to prevent the front filling body 7 from coming off. I'm going.

In addition, this frame body 1 is fixed to a step-shaped mounting base 16 formed on the stairs S with an adhesive or the like, and also has screws 1.
It is reinforced with 7th grade.

Next, a front filling body is fitted and locked to the frame 1,
The details of the anti-slip material 9 in which the rear filling body and the flat anti-slip portion are made separately will be described.

That is, the rear filling body 6 is formed of a flat plate-shaped hard synthetic resin with a thin overall wall thickness in consideration of the cushioning properties and workability of the entire anti-slip material 9.
The installation work is simplified by using the mounting base 16 in which the tread surface _S1 is not stepped.

In addition, the front filling body 7 is required to have more cushioning properties than the rear filling body 6 in order to absorb shocks at the corners when falling, etc. Therefore, at the same time as selecting a material with high cushioning properties, hollow parts are formed inside the front filling body 7. 18 to meet the requirements.

Furthermore, the substantially flat anti-slip portion 8 attached to the upper surfaces of the front and rear fillers 6 and 7 has a plurality of uneven stripes 19 formed on its upper surface in consideration of anti-slip properties and wear resistance. A material with excellent wear resistance, such as urethane resin, is selected.

FIG. 6 shows a modification of the anti-slip material 9 in the above embodiment, in which the locking protrusion 3 forming the deep groove portion 4 of the frame body 1 is protruded diagonally, and the front filling body 7 of the anti-slip material is It is formed into a wedge shape, and is made of a different material from the rear filler, and is made of a soft synthetic resin with high cushioning properties, thereby increasing the shock absorption properties of the corners.

As described above, the anti-slip for buildings according to the present invention exhibits the anti-slip function from the corner of the stairs to the tread by the anti-slip part, and the anti-slip part applied to the front filling body and its upper surface. The front part improves shock absorption near the corners of the stairs and significantly improves the safety of the stairs, and the materials for the front and rear filling bodies are selected to meet the optimal conditions required for each. The front filler is attached to the deep groove of the frame, and the rear filler is attached to the shallow groove of the frame using locking protrusions, so that they are coated on the outer surface of the frame. As a result, the anti-slip material can be firmly attached to the frame, and the shock absorbing properties of the corners can be significantly improved. In particular, since the rear filling body made of a hard material is held by the locking protrusion, displacement due to pedal pressure and accompanying peeling do not occur, and the above-mentioned effect is remarkable.
