Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stair anti-slip device that is attached to the stairs of a building, etc., and particularly relates to an arch that forms double internal and external hollow portions at the most dangerous corners of the stairs. The present invention relates to a non-slip for stairs, which can improve the safety of stairs by forming a cushion part composed of shaped outer and inner bulging pieces to improve shock absorption at the corner of the stairs.

Conventionally, this type of anti-slip for stairs has been made entirely of elastic soft synthetic resin and has a substantially flat shape, and has two components: a tread portion that is fixed to the tread of the stairway, and a riser surface that is fixed to the riser surface of the stairway. and a cushion part connected between these stepping parts, and when several steps are installed on the stairs, the cushion part forms a hollow part at the corner of the stairs and exhibits cushioning properties, and A device has been proposed that improves safety by exhibiting shock absorbing properties when falling down stairs.

However, in such conventional anti-slip stairs, if the thickness of the cushion part is made thin, the cushion part itself easily deforms, making it difficult to provide sufficient cushioning and shock absorption. Since this cushion part is most frequently subjected to pressure when going up and down, it can become fatigued and partially collapse, causing problems with its durability.If the thickness of the cushion part is made thicker, the cushioning properties and shock absorption properties will be significantly reduced. The problem arises that it is degraded.

In view of this point of view, the present invention provides a cushion portion that covers the most dangerous corner of a staircase, with one end attached to a substantially flat tread portion fixed to the tread of the staircase, and the other end attached to the foot-L side of the staircase. a substantially arch-shaped outer bulge that is integrally connected to the riser surface and projects upwardly from the upper surface of the step portion and forward from the front surface of the riser surface; an arch-shaped inner bulging piece having both ends connected to a bottom wall that is integrally connected to the bottom wall and protruding in substantially the same plane as the upper surface of the step portion and the front surface of the riser surface; The outer hollow part is formed toward the step part by the bulging piece and the inner bulging piece facing the outer bulging piece while maintaining a predetermined interval, the inner bulging piece and the bottom wall. To provide a bean stopper for stairs, in which an inner hollow part and an inner hollow part are formed independently from each other, thereby solving various problems such as not only anti-slip shock absorption but also durability and shape retention. It is.

EMBODIMENT OF THE INVENTION Hereinafter, based on the Example shown in an accompanying drawing, the anti-slip for stairs of this invention is demonstrated.

1 and 2, a non-slip for stairs according to an embodiment of the invention is shown.

This stopper includes a step portion 1 fixed to a tread 10 of the stairs 8, a riser surface 3 located on a riser surface 11 of the stairs 8,
A cushion part 4 is located at a corner of the staircase 8 and is integrally connected to the step part 1 and the riser surface 3, and a thin plate provided on the lower surface side of the step part 1, the riser surface 3, and the cushion part 4. When manufactured, the whole is formed into a substantially flat shape, and when installed, it is bent at a substantially right angle from its cushion portion 4 as shown in Figure 2. The width 1 and the riser surface 3 may be formed in advance in the shape of a letter .

The tread portion 1, riser surface 3, and cushion portion 4 are integrally formed from a flexible elastic material such as soft vinyl chloride during molding, and the upper surface of the tread portion 1 is formed into an appropriate shape such as a mountain shape. Anti-slip uneven portions 2 are formed.

The cushion portion 4 has one end attached to the front end side of the substantially flat step portion 1 fixed to the tread 10 of the stairs 8, and the other end attached to the upper end side of the riser surface 3 located on the riser surface 11 of the stairs 8. The tread portion 1) has a substantially arch-shaped outer bulging piece 4a that projects upward from one surface and forward from the front surface of the riser surface 3, and both ends thereof are integrally connected to the tread portion 1 and the riser surface 3, respectively. An arch-shaped inner bulging piece 4b is integrally connected at its end to the bottom wall 12 connected to the bottom wall 12, and projects in substantially the same plane as the upper surface of the step portion 1 and the front surface of the riser surface 3. It is formed toward the tread portion 1 side and the riser surface 3 side by the outer bulging piece 4a and the inner bulging piece 4b facing the outer bulging piece 4a while maintaining a predetermined interval. The outer hollow part 5a, the inner hollow part 5b formed by the inner bulging piece 4b, and the bottom wall 12 are formed independently from each other.

This cushion portion 4 has an outer bulging piece 4 as shown in FIG.
a and the inner bulging piece 4b may be formed to be large, and furthermore, only the cushion portion 4 may be formed of a flexible wear-resistant material such as urethane or nylon.

Furthermore, the thin plate 7 is made of a rigid material such as a rolled metal plate or a hard synthetic resin, and is prevented from adhesion failure or load between the step part 1 constituting the bevel stop and the staircase 8 due to elastic deformation of the riser surface 30. This prevents permanent deformation caused by other factors and maintains shape retention throughout the anti-slip device.

In addition, this thin plate γ has rigidity and can be plastically deformed when the tread portion 1 and riser surface 3 are formed into a substantially flat shape and bent at right angles when installed on the stairs 8. It is formed from a metal plate such as aluminum, and is integrally provided on substantially the entire lower surface of the bottom wall 12 that constitutes the lower surface of the step section 1, riser surface 3, and cushion section 4 during manufacturing.

The thin plate 7 also has the function of imparting rigidity to the anti-slip to facilitate its handling, and increasing the adhesiveness between the stairs 8 and the anti-slip.

Therefore, when attaching to the stairs 8, the thin plate 7 is usually attached in advance with an adhesive 9 provided on the lower surface, or fixed with nails, etc., and the tread portion 1 and the riser surface 3 are attached at the cushion portion 4. is bent so that the cushion part 4 has a substantially right-angled shape, and the cushion part 4 is made to protrude above the tread part 1 and in front of the riser surface 3, so that the tread part 1 and the riser surface 3 are connected to the tread surface 10 and the riser surface of the stairs 8. 11
Install them so that they are in close contact with each other without leaving any gaps.

The present invention has the above-mentioned configuration, and the cushion portion located at the corner of the staircase is formed by an arch-shaped outer bulging piece and an arch-shaped inner bulging piece to form a step portion and a footstep. It has an outer hollow part formed toward the upper surface and an inner hollow part formed independently of this outer hollow part,
Even if the tread pressure load applied to the stair corners when going up and down stairs is absorbed step by step and independently by the arch-shaped inner and outer bulges and the inner and outer hollow parts, the degree of deformation is reduced. The outer bulge piece that makes up this cushion part has one end as a step part, and the other end can be used as a tread part. are integrally connected to the riser surface and protrude above the tread portion and forward of the riser surface, and furthermore, the inner bulge piece has both ends integrally connected to the tread portion and the riser surface, respectively. The outer hollow part is connected to the bottom wall and protrudes almost parallel to the top surface of the tread and the front surface of the riser, so even if a person falls down and hits his/her body violently, the outside hollow part will not be damaged. The impact is effectively absorbed by the deformation of the outer bulging piece, and the inner bulging piece prevents the outer bulging piece from being deformed more than necessary and is still restored, so there is no risk of serious injury. .

Moreover, since the cushion part, especially the outer bulging piece, is made to protrude above the step part, it is possible to produce a thick anti-slip effect by cooperating with the uneven part for sliding on the top surface of the step part.

Furthermore, when the cushion part moves up the stairs, the outer bulging piece is pressed against the corner of the stairs via the inner bulging piece,
However, since the inner bulging piece is pressed through the bottom wall, the inner and outer bulging pieces will not wear out or deteriorate easily from both sides, and the durability will be maintained and the stairs will be improved. It is possible to maintain the cushioning effect and the anti-slip effect at the corners for a long period of time.

The stair slide of the present invention can also be used as a corner of a wall or pillar, or a corner of a veranda.
