Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stair stopper that is improved to be suitable for stairways covered with carpets, felt, mats, etc.

Traditionally, when carpets are placed on stairs, the carpets are usually pasted on the stairs or
It has been fixed to the stairs using a foot presser.

However, with this type of carpet laying method, the carpet is extremely worn out at the tip edge of the stairs, giving people a sense of discomfort between the carpet and the non-slip material, and making long-term use difficult. ing. In addition, conventionally, anti-slip devices for this type of carpet were attached to the stairs from above the carpet at the tip edge of the stairs, but the connection with the carpet was unstable and Because the slip stopper was insufficiently fixed, when it was stepped on, it behaved as if it would fall, which was extremely dangerous.

The purpose of this invention is to simplify the structure so that it can be directly attached to the stair step, to make the installation work simple and easy, and to make it possible to firmly fix it to the step, so that it can be installed directly on the stair step. It securely fixes the rug to the stair, protects the leading edge of the stair, and provides anti-slip and cushioning effects to the leading edge of the stair step. It protects the human body from stairs, and also avoids excessive abrasion of carpets, felt, mats, etc. at the tip edges of stairs, and protects the human body from stairs.
To provide a non-slip for stairs used for stairs covered with carpets, felt, mats, etc., which eliminates incompatibility between felt, mats, etc. and the non-slip, and can be manufactured at low cost.

Hereinafter, preferred specific examples of the stairway stopper according to the present invention will be described with reference to the drawings.

Figures 1 to 3 show a specific example 10 of the anti-slip for stairs of the present invention, which is applied to lay a carpet 30 consisting of a plurality of carpet pieces 31 on a step 41 of a staircase 40 of a building. ing. The stair slip stopper 10 is located on a thin edge base 11 attached to the tread surface 42 of the step 41 so as to cover the tip edge 44 of the step 41, and on the tip edge 44 of the step 41. The edge●heat● is integrally molded on the edge base 11 so that
Cushion 12 and its edge●Heat●Cushion 1
At the rear of the step 41, the gripper 13 is arranged on the edge base 11, and a fastener 14 fixes the gripper 13 together with the edge base 11 to the tread surface 42 of the step 41.

The thin edge base 11 is molded from hard synthetic resin, and is integrally attached to the tip of the riser surface cover 15 attached to the riser surface 43 of the step 41 so as to cover the tip edge 44 of the step 41. Not only does this make it easy to attach the slip stopper 10 of the step 41, but also a front flange 16 extending forward of the riser surface 43 is integrally formed at the tip.

The front flange 16 has an upwardly inclined surface 1 lowered forward.
7, and an insertion groove 18 is formed on the lower surface.

The front flange 16 configured in this manner does not protrude high upwardly from the tread surface 42 of the step 41, nor does it protrude long forward from the riser surface 43 of the step 41. 17 and edge base 11
The edge heat cushion 12, which is integrally molded at the top end, is thickened to improve the cushioning effect and durability of the edge heat cushion 12.
Moreover, damage to the leading edge 44 of the step 41 is effectively prevented.
The edge◆heat●cushion 12 is made of soft synthetic resin, semi-hard synthetic resin, etc. and is integrally molded on the tip of the upper surface of the edge base 11 and the upper inclined surface 17 of the front flange 16, and the rear abutting surface. A flexible cover flap 20 on the tread side is protruded from the tread surface 19, and a flexible cover flap 21 on the riser side is protruded downward from the front so as to cover the tip of the front flange 16. It abuts against the surface 19 and the insertion groove 18, and also covers the front and rear edges of the jacket piece 31 to be inserted, and eliminates overlocking of the front and rear edges of the jacket piece 31. I'm trying to get it. This edge heat cushion 12 has an elastic hollow structure with hollow parts 22 and 23, and not only improves its cushioning effect, but also has a slip prevention surface 24 with a sawtooth cross section formed on the upper surface. Improved anti-slip effect.

As can be understood from FIG. 3, the gripper 13 is formed by processing a band-shaped metal plate, and a large number of protruding claws 25 are protruded from the upper surface of the band-shaped metal plate by roll forming. At this time, the driving groove 26 is formed on the upper surface and the pair of ribs 27 are formed on the lower surface by roll forming.

The driving groove 26 is formed in the center of the plate width by roll forming or the like in a strip-shaped metal plate extending in the length direction, and the fastener 14 is driven in to fix the edge base 11 and the gripper 13 to the tread surface 42 of the step 41. It is designed to hide the head of the person.

As a result, the step or protrusion caused by the head 28 does not appear on the carpet piece 31. In addition, the pair of ribs 27 are formed by bending both side edges of a band-shaped metal plate downward.
This makes it easy to sit on the base 11. Fastener 1
Numeral 4 is a nail driven into the step 41 on the tread surface 42, which firmly fixes the stacked edge base 11 and gripper 13 to the tread surface 42, and protects the edge heat cushion 12 when stepped on. Prevent falls.

Of course, the fastener 14 differs depending on whether the staircase is made of wood or concrete, but it may be a special nail, a wood screw, a self-tapping screw, a self-trilinking screw, a screw for concrete structures, or the like.
