Traditionally, when a carpet is placed on a staircase, the carpet is typically pasted onto the staircase or secured to the staircase using a carpet retainer.

However, with this type of carpet laying method, the carpet is extremely worn out at the edge of the stair step, causing confusion and making long-term use difficult.

In addition, conventionally, anti-slip for this type of carpet has been attached to the leading edge of the stair step from above the carpet to prevent partial wear of the carpet, but this prevents slippage on the stairs. It was difficult to fix the stopper.

The purpose of this invention is to protect the leading edge of each step on the stairs, and to provide a non-slip and cushioning effect to the leading edge of each step on the stairs. It provides protection from stairs, makes it easy and simple to attach to the stair steps, and makes it possible to securely fix the rug to the stair steps. Makes the laying work simple and easy,
Eliminate partial wear of the rug at the tip edge of the stair steps,
It makes it possible to use the rug for a long time without giving people a feeling of discomfort due to the wear of the rug, and in particular, it makes it possible to firmly assemble the rug, and it also makes it possible to easily remove the rug. Used on stairs to cover carpets, felts, mats, etc. that allow the rug to be replaced depending on the degree of wear and damage, and to be washed and reused depending on soiling. The aim is to provide anti-slip products for stairs.

Hereinafter, preferred specific examples of the anti-slip for stairs according to this invention will be described with reference to the drawings.

FIGS. 1 and 2 show a specific example 10 of the anti-slip stairway of this invention, which is applied to spread a tread mat 20 made of a carpet on a step 71 of a staircase 70 of a building.

The anti-slip 10 for stairs is arranged so as to cover the leading edge 74 of the step 71, and the edge base 11 attached to the tread 72 of the step 71, and the edge base 11 that is positioned on the leading edge 74 of the step 71. In addition, an edge bead cushion 12 is formed integrally on the edge base 11, and at the rear of the edge bead cushion 12, the tip side is protruded from the upper surface of the edge base 11. , a large number of sharp claws 13 nailed in two rows at appropriate intervals on the lower surface of the edge base 11, and the edge bead.
It is comprised of a tread side flexible cover flap 14 integrally formed with the cushion 12.

The edge base 11 is molded from hard synthetic resin, and is designed to cover the tip edge 74 of the step 71.
A positioning lip 15 that can be hooked onto the riser surface 73 of the step 71 is integrally formed at the tip, making it easy to attach the anti-slip 10 to the step 71.

Further, the edge base 11 has two rows of driving positioning grooves 16 formed at appropriate intervals on its rear back surface to facilitate driving of the sharp claw 13 and to hide the head of the sharp claw 13.

Of course, this edge base 11 can also be formed from a thin strip-shaped metal plate.

The edge bead cushion 12 is made of soft synthetic resin and is integrally formed on the edge base 11. In particular, the edge bead cushion 12 is located at the front end side of the edge base 11, and is located in the hollow part. 17, which further improves the cushioning effect.

Further, the edge bead cushion 12 has an abutting surface 18 at the rear for abutting against the leading edge of the tread mat 20, and in particular, the abutting surface 18 is inclined.

Furthermore, the edge bead cushion 12 has a transversely serrated anti-slip surface 19 from the top surface to the front surface, thereby improving the anti-slip effect.

A large number of pointed claws 13 are made of rivets, nails, etc., and are attached to the back surface of the edge base 11 so that the pointed end protrudes from the top surface of the edge base 11 at the rear of the edge bead cushion 12. They are driven into the positioning grooves 16 at appropriate intervals, and are fixed to the edge base 11 without the head protruding from the lower surface of the edge base 11.

Of course, it is also possible to heat the actual claws 13 to melt the edge base 11, insert them through the positioning grooves 16 of the edge base 11, and fix them to the edge base 11.

A tread side flexible cover flap 14 is integrally molded above the edge bead cushion 12 so as to project from the inclined abutting surface 18 of the edge bead cushion 12 and is attached to the inclined abutting surface 18 of the edge bead cushion 12. The leading edges of the tread mats 20 to be butted can be covered, and overlocking of the leading edges of the tread mats 20 can be omitted.

Next, a case will be described in which the anti-slip staircase 10 configured as described above is attached to the stairs 70 of a building. As shown in FIG. are driven into the positioning grooves 16 at appropriate intervals and fixed to the edge base 11.
First, adhesive is applied to the back surface of the edge base 11, and then the edge base 11 is positioned on the tip edge 74 of the step 71 by hooking the positioning lip 15 on the riser surface 73 of the step 71. In that state, Edge Base 11
Press it against the tread 72 of the step 71 to make the stair anti-slip 1.
0 to the tip edge 74 of the step 71.

Once the stair anti-slip 10 has been attached to the step 71 in this way, the tread mat 20 is then positioned on the tread 72 of the step 71, and the leading edge of the tread mat 20 is Press it against the inclined abutment surface 18 of the edge bead cushion 12, and from that state further,
The leading edge of the tread mat 20 is pressed onto the edge base 11, the sharp claws 13 are inserted into the tread mat 20, and the tread mat 20 is fixed on the edge base 11.

Thereafter, the tread mat 20 is fixed onto the tread surface 72 of the step 71 by applying an adhesive to the back surface of the tread mat 20 and using an appropriate fastener.

3 to 5 show modified embodiments 30, 40, 50 of the stair cleats of this invention, which stair cleats 30, 40, 50 are also similar to the stair cleats 10 described above. In the same manner, the tread mat is attached to each step 71 of the stairs 70, and in the same manner, the tread mat is fixed to the step 71, and the components correspond to the components of the non-slip 10 for stairs. The same reference numerals are given and their explanations are omitted.

The non-slip 30 for stairs shown in FIG. 3 is made by integrally fixing a metal band-shaped reinforcing plate 32 having a groove corresponding to the positioning groove 16 for driving in the non-slip 10 for stairs to the back surface of an edge base 31. It is.

A plurality of driving positioning grooves 33 extending in the length direction of the reinforcing strip 32 are roll-formed at appropriate intervals, and are positioned above the upper surface of the reinforcing strip 32. , both side edges are bent into embedded edges 34 and 35 so that it can be embedded in the edge base 31.

Of course, the band-shaped reinforcing plate 32 is integrally fixed to the edge base 31 in the extrusion molding machine, and since the edge base 31 is structured in this way, it is of course possible to reinforce itself. This is firmly fixed by the step 71 of the staircase 70, and also fixes the pointed claw 13 more firmly.

The anti-slip for stairs 40 shown in FIG. 4 is a stair anti-slip 10 in which a thin protective layer 41 made of soft synthetic resin is integrally molded into the positioning groove 16 of the edge base 11. By integrally fixing the layer 41 to the positioning groove 16, when the pointed pawl 13 is struck against the positioning groove 16, the thinned groove portion of the edge base 11 is prevented from cracking.

The anti-slip for stairs 50 shown in FIG. It is fixed to the top surface.

That is, the edge base 51 of the anti-slip 50 for stairs has a plurality of driving positioning grooves 52 formed at appropriate intervals on its rear back surface, and in particular, the top wall 53 of the groove 52 is formed on the lower surface of the edge base 51. This gives an inclination angle to the driven sharp claw 13, hides the head of the sharp claw 13, and improves the close contact of the step 71 to the tread surface 72.

In addition, the edge base 51 of this anti-slip 50 for stairs
Since it is provided with a thin foamed surface layer 54 on its upper surface, the anti-slip staircase 50 further improves the prevention of the sharp nails 13 driven into the edge base 51 from being pulled out.
