Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stair slip stopper that is used by attaching it to the stairs of buildings, etc., and particularly improves the safety of the stairs by increasing shock absorption at the most dangerous corners of the stairs. Concerning the prevention of slippage for stairs that can be used.

Conventionally, this type of stair stopper has been made entirely of elastic soft synthetic resin and has a substantially flat shape, and has a tread portion that is fixed to the floor surface of the stairs, and a riser that is fixed to the riser surface of the stairs. It has an upper part, and a cushion part that connects between these tread parts and the riser part, and when installed on the stairs, the cushion part forms a hollow part in the corner part of the stairs and exhibits cushioning properties. , It also exhibits shock absorption properties when falling down stairs,
Some proposals have been made to ensure safety.

However, in such conventional anti-slip staircases, when the thickness of the cushion part is made thin, the cushion part itself easily deforms, making it difficult to exhibit sufficient tension and shock absorption properties. Since this cushion part is most often subjected to pressure when going up and down stairs, it can become fatigued and partially collapse, causing problems with its durability.Additionally, increasing the thickness of the cushion part will reduce its cushioning properties and shock absorption. The problem arises that the sexual quality is significantly reduced.

In view of this, the present invention provides a cushion portion that covers the most dangerous corner of a staircase by forming a hollow portion with an arch-shaped bulging piece and a flat bottom wall, and in which a plurality of cushion portions are formed. A cylindrical reinforcing rod is connected to the bulging piece and the bottom wall with ribs, and a buffer section is partitioned into multiple parts to improve shock absorption at the corners of the stairs, and to prevent the most frequent damage when going up and down. To provide a stair stopper that can always maintain the safety of stairs by preventing deformation of a cushion part that is repeatedly stepped on.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the road surface anti-stick device of the present invention will be described based on embodiments shown in the accompanying drawings.

1 and 2, a stairway stopper according to an embodiment of the invention is shown.

This anti-slip device includes a step portion 1 fixed to the road surface 12 of the stairs 11, and a riser portion 3 located on the riser surface 13 of the stairs 11.
and a cushion part 4 located at a corner of the staircase 11 and integrally connected to the step part 1 and the riser part 3, the step part 1,
It is composed of a riser part 3 and a thin plate 6 provided on the lower surface side of the cushion part 4, and when manufactured, the entire part is formed into a substantially flat shape, and when installed, the cushion part is flat as shown in FIG. Although it is used by being bent at a substantially right angle from 4, it is also possible to form the step part 1 and the riser part 3 in an L-shape in advance. The above step section 1, riser section 3 and cushion section 4
is made of a flexible elastic material such as soft vinyl chloride, and is integrally formed during molding, and on the upper surface of the riser portion 1, a slip-preventing uneven portion 2 formed in an appropriate shape such as a mountain shape is formed. There is.

The cushion part 4 has one end on the front end side of the substantially flat step part 1 fixed to the tread 12 of the stairs 11, and the other end on the front end side of the tread part 1 fixed to the tread 12 of the stairs 11.
substantially arch-shaped bulging pieces that are integrally connected to the upper end sides of the riser parts 3 located on the riser faces 13 of the step part 1 and project upward from the upper surface of the step part 1 and forward from the front surface of the riser parts 3; 5 and a flat bottom wall 8 whose end portions are integrally connected to the step portion 1 and the riser portion 3, forming a hollow portion 7.

This hollow portion 7 is provided with a cylindrical reinforcing rod 10 connected by a plurality of ribs 9 extending from the inner surface of the arch-shaped bulging piece 5 and the flat bottom wall 8. A large number of cavities 7a are formed which are partitioned by a plurality of ribs 9 and reinforcing rods 10. Note that only the cushion portion 4 may be formed of a flexible and wear-resistant material such as urethane or nylon. Furthermore, the thin plate 6 is made of a rigid material such as a metal plate or a hard synthetic resin, and may be caused by poor adhesion to the stairs 11 due to elastic deformation of the step part 1 and riser part 3, which constitute the anti-slip part, and by loads. This prevents permanent deformation caused by the slip and maintains shape retention throughout the slip prevention.

In addition, this thin body 6 has the step portion 1 and the riser portion 3 formed into a substantially flat shape, and has rigidity and is resistant to plastic deformation when it is bent at right angles when installed on the stairs 11. The tread portion 1 is formed from a metal plate such as aluminum, which is possible;
It is integrally provided on substantially the entire lower surface of the bottom wall 8 that constitutes the lower surfaces of the riser portion 3 and the cushion portion 4 during manufacturing.

Further, the thin plate 6 has the function of imparting rigidity to the slip stopper to facilitate its handling, and also has the function of increasing adhesiveness between the stairs 11 and the slip stopper. The present invention has the above configuration, and the cushion portion located at the corner of the staircase forms a hollow portion with an arch-shaped bulging piece and a flat bottom wall. In the hollow part, a plurality of ribs form a cylindrical reinforcing rod connected to the bulging piece and the bottom wall, and the interior is partitioned into a plurality of parts to provide a buffer part to improve the shock absorption of the corner part of the stairs. At the same time, the safety of the stairs can be maintained at all times by preventing deformation of the cushion part, which is most frequently subjected to repeated pressure when going up and down the stairs.

The stairway stopper of the present invention can also be used as a corner stopper for walls, pillars, edges, etc.
