Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-slip material used for stairs laid with jutan.

In recent years, it has become common for businesses to cover dangerous staircases with carpets and carpets, especially on the stairs, in order to improve the safety of their families, improve customer service, or improve the image of the store itself.

However, the carpets and carpets located at the corners of these staircases wear out quickly and are unsightly because they are used with the base exposed, and even parts such as the treads that are still usable must be replaced. It was extremely uneconomical.

For this reason, non-slip metal fittings made of aluminum or brass are installed at the corners of frequently used double-sided stairs, but in order to install these types of non-slip metal fittings, the double-sided wooden stairs at the corners of the stairs must be cut away or In addition to requiring a curing period for the adhesive used in the metal fittings, fasteners such as screws tend to loosen due to the flexibility of jutan and carpet, making it difficult to provide sufficient durability. Often requires repair work.

In addition, the present inventor has already devised a rug edge fixing device that attempts to solve the above problem by integrally providing a thin plate with a locking claw that is inserted into the rug on the lower surface of the flexible presser piece. However, since all the locking claws are formed on a thin plate that is integrated with the holding piece, the thin plate increases the rigidity.
It prevents the plasticizer from seeping out, and the flexible holding piece allows it to adapt to the thickness of the rug and follow the flexibility of the rug, making it less likely to come off. It has not yet been possible to increase or decrease the number of claws easily.

The present invention has been made in view of the above-mentioned conventional anti-slip metal fittings for stairs with jutan flooring. A plurality of pointed locking protrusions independent of the anti-slip body are inserted into grooves provided in the longitudinal direction on the back surface of the anti-slip body to form a group of protrusions on the back surface of the non-slip body to engage with the jutan. To provide a non-slip material for stairs with a carpet floor, which allows easy installation of locking protrusions and allows the number and arrangement of the locking projections to be freely adjusted according to the type of carpet.

The configuration of the present invention will be explained based on the embodiments shown in the accompanying drawings.
The anti-slip main body 1 is made of a flexible soft synthetic resin material such as vinyl chloride resin or polyurethane, and is a wide flat plate portion with numerous anti-slip uneven stripes 2 on the upper surface that is fixed to the treads of the stairs 11. A front fixed edge 6 that is fixed to the riser surface of the stairs 11 is continuously hung at the tip of 3, and an arc-shaped expansion having a hollow 4 inside is provided at the corner of this flat plate portion 3 and the front fixed edge 6. The projecting portion 5 is formed so that the entire body is shaped like an abbreviated character, and as shown in FIG.
has been established.

This anti-slip main body 1 is formed in advance into an abbreviated shape as shown in FIG. 1, but is also formed into a flat state as shown in FIG. It is attached to the carpet 7 that has been laid.

Therefore, numerous grooves 14 .
4, as shown in FIG. 3, a thank-you card insertion part 10 made of flexible aluminum or the like is formed on the base side independent of the anti-slip body 1, and an extension part 10 is formed on the lower surface of this insertion part 10. A plurality of pointed locking protrusions 9 having a detent part 8 are inserted into the provided shaft part 15 to form a protrusion group a on the back surface of the anti-slip body 1.
It is locked and fixed to the jacket 7 which is laid on the stairs.

The locking protrusions 9 constituting the protrusion group a may be formed with shaft parts is, is at both ends of the insertion part 10 as shown in FIG. As shown in FIG. 7, the detent portion 8 formed on the shaft portion 15 can be modified in various ways.

In addition, as shown in FIG. 5, the insertion part 10 of the letter of appreciation is formed into a semicircular arc shape, and its peripheral edge is extended, and the certificate is inserted while strongly pressing the side wall of the groove 14 of the non-slip main body 1. However, by forming the groove 14 into a substantially T-shaped cross section that widens slightly on the bottom wall side, and using the locking protrusion 9 equipped with the insertion portion 10 having a shape corresponding to the groove 14. ,
The removal and insertion work can be easily performed together with the stopper.

To attach it to the jumper 7, place the flat plate part 3 of the anti-slip body 1 on the tread of the stairs 11, and attach the front fixed edge 6 to the stair 11.
The protrusion group a on the lower surface of the non-slip main body 1 is inserted and fixed by pressing the protrusion group a on the lower surface of the non-slip main body 1 so as to wrap it around the weaving yarn of the jutan 7.

The present invention has the above-mentioned configuration, and the anti-slip body 1 is made of a flexible soft synthetic resin material so as to be able to adapt to the elastic deformation of the tongue 7, and the back side of the anti-slip body 1 A plurality of pointed locking projections 9, which are independent of the anti-slip body 1, are inserted into a groove 14 provided in the longitudinal direction of the anti-slip main body 1, and are locked by a projection group a formed by inserting a plurality of pointed locking projections 9. The number and arrangement of the locking protrusions 9 can be freely adjusted to the jute tongue 7 so that the anti-slip body 1 can be attached so as not to be easily peeled off.

In addition, since the shaft portion 15 of the locking protrusion 9 is provided with a detent portion 8 that entangles with the hair and threads of the jutan 7 and prevents it from coming off, the non-slip main body 1 can be inserted directly from above the jutan 7. It can be installed by pressing, eliminating the traditional cutting process of laying the jutan except for the corners of the stairs, the work of directly gluing or screwing the non-slip metal fittings to the stairs, and the installation curing period. The work can be easily carried out without damaging the surface of the jacket 7 by drilling holes or applying adhesive to the attachment part of the jacket 7.
