Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stair anti-slip device attached to a stairway.

In general, anti-slip devices for stairs are composed of a main part that is fixed to the stair tread by forming anti-slip uneven parts on the upper surface, and a front fixing part that is fixed to the riser surface of the stairs. A non-slip device has been proposed in which hollow strips are formed inside the main body to improve the overall cushioning effect and the feeling when stepping on the foot (Japanese Utility Model Publication No. 1401/1983).

However, in the above-mentioned case, the corners are formed with a thick wall in order to ensure a cushioning effect at the corners, but for this reason, the fleshy part of the main body located above the hollow strip is in the direction parallel to the tread surface. As a result of this, the hollow strips only function as a relief for the fleshy part in the direction of force that is approximately perpendicular to the tread surface, which has the drawback that it cannot be expected to improve the overall tread feel. Met.

In other words, ensuring the cushioning effect of the corners and improving the overall tread feel of the non-slip for stairs each work as contradictory factors, and a non-slip for stairs that satisfies both has not yet been proposed.

In view of this point of view, it is an object of the present invention to provide a non-slip for stairs that has an excellent cushioning effect at corners and has an improved overall tread feel.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

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

This anti-slip has an uneven part 2 for anti-slip in the longitudinal direction on the upper surface, and has two hollow strips 3 in the longitudinal direction inside, and is fixed to the tread 10 of the stairs 9. A flat belt-shaped non-slip main body part 1, a substantially flat belt-shaped front fixing part 4 fixed to the riser surface 11 of the stairs 9, and a non-slip main part 1 that connects the non-slip main part 1 and the front fixing part 4 and prevents the above-mentioned slip. These bulges are composed of a bulge 6 which has an arch-shaped cross section and which protrudes above the uneven part 2 formed on the upper surface of the stop main body 1, and a bottom 7 which is fixed along the corner 12 of the staircase 9. It consists of a hollow connecting part 5 that forms a hollow part 8 located at the corner part 12 of the staircase 9 between the protrusion part 6 and the bottom part 7, and the whole is made of a flexible material such as soft vinyl chloride resin. Molded.

The hollow strips 3 serve as a relief for the fleshy part of the non-slip main body 1 when stepping pressure is applied to the non-slip main body 1, thereby improving the overall treading feeling. In the present invention, The fleshy part of the anti-slip main body 1 is the tread 1 of the stairs 9.
It is configured so that it can easily move along a plane parallel to zero.

That is, the bottom portion 7 and the anti-slip main body portion 1 are connected and fixed to each other below an imaginary plane that includes the bottom surface of the hollow strip 3 and is parallel to the tread 10 of the stairs 9.

By doing so, the hollow portion 8 formed between the hollow connecting portion 5 and the bottom surface 7 extends along the tread surface 10 of the fleshy portion located above the bottom surface of the hollow strip 3 of the anti-slip main body portion 1. This provides relief when moving, further improving the overall feeling of stepping.

In this embodiment, the anti-slip main body part 1 and the front fixing part 4 are formed so as to be located on substantially the same plane via a hollow connecting part 5, and are bent from the hollow connecting part 5 when installing to the stairs 9. Both the bulging part 6 and the bottom part 7 of the hollow connecting part 5 are formed thinner than the anti-slip main body part 1 and the front fixing part 4, and the bottom part 7 also has a central part. A bending strip 13 is formed along the hand direction, making it easy to bend during installation.

Further, a pressure-sensitive adhesive sheet 14 whose lower surface side is protected by a release paper 15 is integrally or integrally provided on the lower surface of the bottom portion 7 of the anti-slip main body portion 1, the front fixing portion 4, and the hollow connecting portion 5. By peeling off the release paper 15 during installation, it can be adhesively fixed to the stairs 9.

Therefore, according to the anti-slip building of this embodiment, when installing it on the stairs 9, the release paper 15 protecting the pressure-sensitive adhesive sheet 14 is first peeled off, and then the treads 10 of the stairs 9 are removed.
The non-slip main body part 1 is glued and fixed to the hollow connecting part 5.
is bent along the bending line 13 formed on the bottom part 7,
The front fixing part 4 may be pressed against the riser surface 11 of the stairs 9 and bonded.

As described above, the anti-slip for stairs according to the present invention includes the bottom surface of the hollow strip 3 formed in the anti-slip main body part 1, and the bottom part 7 which is fixed to the corner 12 of the staircase 9 and cannot be expected to undergo elastic deformation. By connecting and fixing one end of the non-slip main body 1 below a plane parallel to the tread surface 10, the fleshy part of the non-slip main body 1 located above the hollow strip 3 is oriented in a direction parallel to the tread surface 10. By providing an escape area for movement, the cushioning effect in the above-mentioned direction is enhanced, and in combination with the hollow strips 3 which enhance the cushioning effect in the direction perpendicular to the tread surface 10, the overall tread feeling can be improved.

Moreover, at this time, the corners 12 of the stairs 9 do not have any cracks that reduce the cushioning effect due to the hollow connecting portions 5.

Therefore, the cushioning effect at the corner portion 12 is excellent, and the stepping feeling as a whole can be improved.

That is, the hollow connection part 5 covering the corner part 12 of the staircase 9 exerts a shock-absorbing property at the corner part 12 of the staircase 9, and when going up and down, you may stumble on the riser surface 11 or step over several steps. Even if you hit your knees or fall down, the bulge 6 of the hollow connecting part 5 that protrudes upward from the top surface of the anti-slip main body 1 is formed between the bottom γ of the bulge 6. The first hollow part 8 is deformed to the extent allowed and absorbs the impact, and furthermore, the bulge part 6 and the bottom part 7 formed of a soft flexible material are compressed between the corner part 12 of the staircase 9. It absorbs the impact when being hit, minimizes bruises, and prevents serious injuries such as broken bones and internal bleeding.

Further, the hollow connecting part 5 covering the corner part 12 of the staircase 9 is fixed along the corner part 12 of the staircase 9 to a bulging part 6 having a substantially arch-shaped cross section that projects upward from the upper surface of the anti-slip main body part 1. A hollow part 8 located at the corner part 12 of the stairs 9 is formed between the bulging part 6 and the bottom part 1, so that when an impact such as tread pressure is applied, the hollow part 8 is the largest. The stress caused by the elastic deformation of the deforming bulge 6 does not directly affect the bonding surface and is not concentrated locally, and even if the bulge 6 is largely elastically deformed, it does not tighten locally. There is no occurrence of phenomena such as partial peeling or floating.

In addition, as shown in phantom lines in FIGS. 2 and 3, when a tread pressure A is applied substantially vertically or diagonally from the upper edge of the tread 10 of the stairs 9, the bulge 6 6 deforms toward the corner 12 of the staircase 9, but this corner 12 is covered with the bottom 7, and especially after the back surface of the bulge 6 comes into contact with the bottom 7, the bulge 6 and the bottom 7 is compressed at the same time, and the back surface of the bulge 6 is not directly strongly pressed or rubbed against the hard, sharp corner 12, which prevents abrasion of the bulge 6 and increases its durability. This will improve your performance.

Furthermore, an anti-slip main body part 1 having an uneven part 2 for anti-slip on the upper surface and a hollow strip 3 inside is fixed to the tread 10 of the stairs 9, and a non-slip main part 1 is fixed to the corner part 12 of the staircase 9. Since the bulging part 6 which has a generally arch-shaped cross section and which protrudes upward from the upper surface of the part 1 forms a hollow part 8, the main body part is prevented from slipping when going up and down, as shown by the imaginary line in FIG. 1 and the bulge 6, the anti-slip main body 1 and the bulge 6 do not elastically deform and come into contact with the sole of the foot over a wide area, which simply prevents the wear of the corner 12 of the stairs 9. It not only prevents slipping, but also actively prevents slipping on the tread surface 10, significantly improving the anti-slip effect.Moreover, the elastic cushioning properties of the anti-slip main part 1 and the bulging part 6 make the tread smoother. It can improve the feeling.

In addition to molding the anti-slip main body part 1, front fixing part 4, and hollow connecting part 5 from the same material such as soft vinyl chloride resin, considering wear resistance, flexibility, installation workability, usage conditions, etc. A portion of the anti-slip uneven portion 2, bulge portion 6, etc. may be molded using a different material such as urethane resin.
