Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building anti-skid device that is attached to the stairs of a building, and more particularly to a building anti-skid device that is composed of a frame and a non-slip material that is attached to the frame.

Traditionally, the structure consists of a metal concrete that is fixed from the riser surface to the tread at the corner of a staircase, and an elastic shock absorber that is removably fitted into a fitting groove formed on the metal concrete. There is a non-slip structure for buildings in which the elastic shock absorber can be replaced and repaired if it becomes worn or deteriorated.

However, in such conventional anti-skid structures for buildings, the elastic shock absorber is formed of only a single layer, and in addition, the protrusions that form the fitting grooves in Kinogata are located on the front side of the corners of the stairs. This position impairs shock absorption at this angle, and there is a danger that if a person falls down, they may hit the protrusions on this corner and cause unexpected serious injury.

Additionally, in order to improve this point, it has been proposed that the ridges of metal concrete are lowered slightly from the corners on the riser side of the stairs so that the corners of the stairs are almost completely covered with an elastic buffer. In this case as well, the elastic buffer is formed of a single layer, and if the thickness of the elastic buffer is increased, the protrusion from the treads and risers at the corners of the stairs will increase.
There is a limit to increasing the thickness of the elastic shock absorber to improve its shock absorption properties, as there is a risk of tripping, especially at the corners of stairs. It has been difficult to exhibit sufficient shock absorption to the extent that it can be said to be safe even in the event of a collision.

In view of this point of view, the present invention provides that the frame body into which the anti-slip material is fitted has a deep groove portion in its front portion that is open at least on the upper side and the upper front side, and that the rear portion has a deep groove portion that is open at least on the upper side and the upper front side. It has a structure that has a shallow groove-shaped attachment part formed by a flat part continuous to the upper edge and extending to the rear side and a rising protrusion facing upward, and also has a non-slip material. , consisting of a filling part that fits into the deep groove part of the frame and a flat part that is attached to the shallow groove-shaped attachment part, and a surface layer with high wear resistance on the upper surface side of the filling part and the flat part, This surface layer and the intermediate layer on the lower surface thereof are formed from soft synthetic resin materials having different hardnesses, and a hard layer formed of a hard synthetic resin material is provided on the lower surface of the intermediate layer, and is engaged with the frame body. The surface layer prevents slips when people going up and down, and the surface layer is made of soft synthetic resin materials with different hardness and absorbs and softens the shock. It can efficiently and effectively absorb the large shock that occurs when falling down, improving the safety of stairs. To provide a non-slip for a building, which is firmly engaged with a frame body through its layers, and in which each layer can be easily replaced even if it deteriorates.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

1 and 2 show a non-slip structure for buildings according to an embodiment of the present invention. This non-slip for building is composed of a frame 1 and a non-slip material 2 attached to the frame 1, and is fixed to a corner A of a staircase S from a riser surface 20 to a tread surface 19.

The frame 1 is made of a rigid material such as a metal such as stainless steel, aluminum, or brass, or a hard synthetic resin, and has a horizontal wall in its front portion (in the direction of arrow B in FIG. 1, the same applies hereinafter). 11
A locking protrusion 12 with a relatively small protrusion dimension is formed at the tip of this horizontal wall 11 and protrudes upward (in the direction of arrow D in FIG. 1, the same applies hereinafter).
and a straight wall 13 which is formed at the rear end (in the direction of arrow C in FIG. 1, the same applies hereinafter) of the horizontal wall 11 and has a relatively large protruding dimension that protrudes upward. Deep groove portions 3 each having an approximately L-shaped cross section are formed with openings on the front side, and
In the rear portion thereof, a flat portion is provided at the rear upper edge of the deep groove portion 3 and extends rearward along the upper end extension line of the straight wall 13 via a protrusion 15 that projects upward. A shallow groove-shaped mounting portion 4 having an upwardly rising projecting piece 5 following the mounting portion 4a is formed.

The anti-slip material 2 also includes a thick filling part 6 which is removably fitted into the deep groove part 3 of the frame 1, and a flat part which is removably fitted into the shallow groove-shaped attachment part 4. It consists of 7. The filling part 6 has a surface layer 8 having excellent wear resistance on the upper surface side, and an intermediate layer 9 integrally formed on the surface layer 8 and the lower surface thereof.
and a soft layer 1 formed on the lower surface of this intermediate layer.
0 are made from soft synthetic resin materials with different hardnesses, allowing for high elastic deformation and shock absorption. Furthermore, the filling part 6 has a hard layer 24 formed of a hard synthetic resin material on the lower surface side thereof.
When fitted together, the engaging end 18' formed on the distal end side is engaged with the locking protrusion 12 of the deep groove 3, so that the fitting can be firmly performed.

Note that the reference numeral 22 is a hollow protrusion provided on the soft layer 10 formed on the lower surface of the intermediate layer 9, and the hollow protrusion 22 improves the impact absorption properties of the composite layers having different hardnesses, including the surface layer 8. It is becoming more and more effective.

Further, the flat part 7 is formed of two upper and lower layers F and G that are continuous to the surface layer 8 and the intermediate layer 9 of the filling part 6, respectively, and these two layers are shallower than the flat part hard layer 23 provided at the bottom layer. It is firmly fitted into the groove-shaped attachment part 4.

In the anti-slip material 2, anti-slip uneven strips 16 are formed on the upper surface of the surface layer 8, and between the lower layer G and the hard layer 23 constituting the flat portion 7, the cushion of the flat portion 7 is formed. Hollow strips 17 are formed to improve the performance and feel of the pedal.Furthermore, at the rear end of the flat part hard layer 23 constituting the flat part 7, a shallow groove-shaped attachment part 4 of the frame body 1 is formed. An engaging end 18 is formed to be fitted and locked to the rising protrusion 5 provided on the holder. A locking groove 14 is formed between the filling part 6 and the flat part 7, and the protrusion 15 of the frame body 1 fits and locks therein. The anti-slip material 2 is firmly fitted into the shallow groove-shaped attachment portion 4 of the anti-slip material 2 and is prevented from shifting forward as a whole.

When installing the building anti-slip of this example on the stairs S, as shown in Fig. 2,
The part where the deep groove part 3 of the frame 1 and the shallow groove-shaped attachment part 4 are fixed by installing a fixed tree (not shown) from the riser surface 20 of the staircase S to the corner of the tread surface 19 during finishing construction. A step-shaped mounting base 21 is formed, a frame 1 is adhered to this mounting base 21, and a non-slip member 2 is fitted onto this frame 1. In addition to the above-mentioned adhesion, the frame 1 can be fixed by reinforcing it with embedded plugs or screws, or by using anchors installed on the back side of the frame 1 during finishing construction of the stairs S. may be buried and fixed. In addition,
In FIG. 1, the reference numeral 25 is the riser surface 20 of the stairs S.
and a finishing material pasted on the tread surface 19.

FIG. 3 shows a modification of the anti-skid structure for buildings according to the above embodiment.

This anti-slip for buildings has a frame 1 made of copper plate,
It is made by bending and forming a metal plate material such as a stainless steel plate, and the anti-slip material 2 extends to the front side and upper surface layer 8 of the filling part 6 and the upper surface of the flat part 7 that is continuous with this surface layer 8. The upper layer F is formed of a soft synthetic resin material with excellent wear resistance, such as urethane resin or nitrile rubber, and covers the entire surface of the anti-slip material 2 in a substantially L-shape.

In addition, the intermediate layer 9 of the filling part 6 and the lower layer G formed on the lower surface of the flat part 7 are continuously formed in a substantially L-shape from a general-purpose soft synthetic resin material such as vinyl chloride resin. The soft layer 10 of the filling part 6 is made of a soft synthetic resin material having a hardness different from that of the intermediate layer 9, and has hollow strips 22 to exhibit excellent cushioning properties. Moreover, the hard layer 24 on the lower surface side of the filling part 6 and the flat hard layer 23 of the flat part 7 firmly and stably fit and hold the anti-slip material 2 .

This anti-slip structure for buildings has an intermediate layer of a filling part 6 which exhibits excellent shock absorption properties and cushioning properties at the corner of the stairs S, and a lower layer G of a flat part 7, and a wear-resistant surface layer 8 and an upper layer. Since it is covered with F, the durability of the anti-slip material is significantly improved.

As described above, the present invention includes a frame body having a deep groove portion and a shallow groove-shaped attachment portion continuous to the rear upper edge of the deep groove portion and fixed from the corner of the staircase to the tread;
It has a thick-walled filling part that fits into the deep groove part and a flat part that is attached to the attachment part, and has a surface layer and an upper layer with excellent wear resistance on the upper surface side, and the surface layer, the upper layer, and the upper layer. The intermediate layer and lower layer on the lower surface are made of soft synthetic resin materials with different hardnesses, and the anti-slip layer is provided with a hard layer and a flat hard layer in the deep groove part of the frame material on the lower surface side and the engagement part with the mounting part. Since the above-mentioned filling part is constructed with a material made of aluminum, the impact absorption properties at the corners of the stairs are particularly exhibited.In other words, the corners of the stairs can not only absorb impacts from above, but also absorb impacts from diagonally and from the front. In addition, the surface layer and intermediate layer, which have different hardness, can sequentially absorb the impact that acts on the filling part located at the corner of the stairs based on the difference in hardness. As a result, it is possible to efficiently and effectively absorb from relatively small impacts to large impacts that occur when the user does not fall.Furthermore, the filled part and flat part of the anti-slip material The hard layer and flat hard layer individually engage the deep groove and the shallow groove-like mounting portion, so the anti-slip material does not shift forward without compromising replaceability. This allows for a firmer grip, significantly improving the safety and durability of the stairs.
