Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a non-slip material for stairs, and relates to an improved anti-slip material provided at the corners of stairs where people go up and down.

BACKGROUND OF THE INVENTION Stairs in houses, office buildings, etc. are frequently used by people to go up and down. The soles of footwear often touch the corners of such stairs, especially when descending them. Therefore, there is a risk of slipping on these corners and missing your step on the stairs, so anti-slip materials are installed to prevent footwear from slipping even if the soles of your footwear are to step on the corners of the stairs. There is.

This kind of anti-slip material is made from Utility Model 104615
Publication No. 51-92929, Utility Model Application No. 52-
As described in Publication No. 16219 and Japanese Utility Model Application Publication No. 55-92818, a buffer portion made of soft synthetic resin is provided at the corner of a substrate made of hard synthetic resin and having a substantially L-shaped cross section through a gap. It is shown.

All of these have a buffer section with a gap in the corner to relieve pressure from above. In particular, in the case of a cushion part 6 corresponding to a buffer part protruding upward from the horizontal piece 2, such as the one described in Japanese Utility Model Application Publication No. 55-92818, the gap becomes large. Therefore, its buffering capacity has increased.

However, although the above-mentioned conventional type has a large buffering effect from above, the inclined surface of the hard substrate and the front surface of the buffer section are configured to form almost the same plane, and the gap in the front and rear direction is relatively large. Because they are small, these cushioning parts have a small cushioning effect against the impact from the front when you miss a step on the stairs.
When a person falls or falls, the impact from the front is not alleviated, and the person's body is hit directly, causing not only the pain of the impact but also the risk of injury. this is,
Although some improvement has been made in the case of the one described in Utility Model Application Publication No. 55-92818, in which the buffer part is made to protrude upward and the gap is enlarged, the buffer function is still insufficient. Not only is it not possible, but when a person is trying to go down the stairs in a hurry,
Another major drawback is that the toes and the corners of the heel of the shoe tend to get caught in this upward protrusion, creating the risk that the user's foot will be taken off, causing him to lose his weight balance and fall downward.

In addition, in all of the anti-slip materials described in the above publications, the cushioning section exerts treading pressure on the hard substrate almost from above to below, so when this cushioning section is stepped on, the sole of the footwear becomes cushioned. When the direction of pressure is gradually changed from the top to the side of the part, this buffer part is forced to deform as if rolled inward, and as a result, a shearing force is generated at the end of the joint part, so that the contact with the hard substrate is forced. Either the base is subjected to concentrated stress that would cause it to be torn off, or if the bonding force at the base is large, the sides of the buffer are excessively deformed, making it uncomfortable to step on, and if this is repeated, the elasticity will deteriorate. It also had the disadvantage of causing fatigue, impairing its elastic function and rendering it useless, and greatly reducing its durability.

Furthermore, anti-slip materials whose hard substrates have a roughly L-shaped cross section, such as those described in the above-mentioned publications, are often fixed to the treads of stairs with nails or adhesives. However, if you are not careful when installing these, the lower end of the hard board will often be fixed in a state that protrudes in front of the riser surface. Your finger may hit the corner or the edge of the lower end, causing severe pain or even injury.

Problems to be Solved by the Invention As described above, conventional anti-slip materials have little cushioning effect in the front and back direction in the buffer part, and even if the upper part of the buffer part is made to protrude and the gap is enlarged, Not only does it fail to increase the cushioning effect in the direction, but it also has the disadvantage that shoes, etc., may get caught and become dangerous.There is also a problem with the support structure for the tread pressure in this cushioning part, and furthermore, the lower end of the hard board and the upper surface of the There is also a problem in the case where a gap is formed between the contact portions, and an improvement has been desired.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a horizontal plate part located on the tread of the stairs, a lower end of which is almost in contact with the riser surface of the stairs, and an upper part of the horizontal plate part that is placed on the riser surface of the stairs. A substantially L-shaped cross-sectional shape having an inclined plate portion located at a position gradually spaced apart from the front, and a stepped bent portion integrally provided between the upper end of the inclined plate portion and the horizontal plate portion. A hard substrate is formed, and a gap is provided between a horizontal covering part that is coupled to the upper surface of the horizontal plate part and the stepped bent part that extends horizontally from the front end of the horizontal covering part. a curved covering section provided between the front end of the extended covering section, the front end of the stepped bent section, and the upper end of the inclined plate section; In the anti-slip material for stairs, which is integrally provided on the above-mentioned hard substrate, a plurality of anti-slip parts each having a plurality of uneven stripes are arranged at intervals on the upper surface of the horizontal covering part, and the upper surface of the extended covering part is formed lower than the upper surface of the ridge, and the curved covering part is formed in a substantially semicircular shape and protrudes forward from the front end of the extension covering part and the upper end of the inclined plate part, and the lower end thereof is curved. The present invention is characterized in that a slightly thick soft end covering material is integrally connected to the corner portion located on the direction extension and further curved and protruded downward and forward at the lower end of the inclined plate portion. The present invention provides an anti-slip material for stairs.

Function Since the curved covering part protrudes forward from the inclined plate part, there are many voids in the front and back direction, and the buffering capacity in the front and back direction can be increased. The upper surface of the extended covering part provided horizontally and the curved covering part provided in front of it are formed lower than the upper surface of the ridges provided on the horizontal covering part, so that the toes of the foot and the heel of the shoe are The corners do not catch. In addition, even if the extension covering part or the curved covering part is subjected to stepping pressure by feet or shoes that gradually changes direction, the pressure will be applied to the extended covering part or the curved covering part in a stepped manner with the hard substrate on the extension in the curved direction. Since it is connected to the corner of the bent portion and is received without difficulty, no shearing force is applied to this joint, and excessive deformation of the curved covering portion can be suppressed.
Further, since a soft end covering material having a curved surface is provided at the lower end of the hard substrate, it is possible to reduce the gap with the riser surface and to soften the contact with fingers.

Next, one embodiment of the present invention will be described based on FIGS. 1 to 3.

Reference numeral 1 denotes a hard substrate, and the hard substrate 1 is formed into a substantially L-shaped cross section by extrusion molding of hard synthetic resin, etc., and has a horizontal plate portion 1a located on the tread 10a of the stairs 10, and a riser surface 10b of the stairs. an inclined plate part 1b whose lower end is in almost contact with the riser surface and whose upper part is gradually spaced forward from the riser surface and which bulges slightly outward;
It consists of a stepped bent part 1c provided between the inclined plate part 1b and the horizontal plate part 1a.

Further, 2 is a soft covering material, and this soft covering material 2 is molded integrally with the above-mentioned hard substrate 1 using a soft synthetic resin. An extended covering part 2b extending horizontally from the front end of the covering part to the stepped bent part 1c through a gap, and a front end of the extended covering part and the front end of the stepped bent part 1c. A curve formed in a semicircle between a corner where the upper end of the inclined plate part 1b intersects, and the corner is located on an extension of the curved direction of this semicircular curve and joined to this corner. It has a covering part 2c. The lower part of the horizontal covering part 2a has longitudinal grooves 2a-1, 2a-1, 2a.
-1 are provided in three pieces spaced apart in the width direction, and furthermore, on the upper part of the horizontal covering part 2a facing these grooves, there is an uneven strip 2a having a sawtooth shape in cross section and projecting upward.
-2, 2a-2, 2a-2 are provided in the length direction, and the upper surface of the extension covering portion 2b is formed lower than the upper surface of the protruding strips of these uneven stripes.

Further, 3 is an end covering material made of a soft material, which is integrally provided along the lower edge of the inclined plate part 1b,
The outer surface is a curved surface that is curved and protruded downward and forward, and is formed so that it can come into contact with the riser surface of the stairs when the anti-slip material of this embodiment is attached to the stairs.

Further, reference numeral 4 denotes a bonding portion consisting of an adhesive layer provided on the lower surface of the hard substrate 1 and a release layer thereon.

Further, reference numeral 5 denotes a horizontal end member provided between the hard substrate 1 and the soft covering material 2 so as to reduce the gap between it and the tread of the stairs.

The anti-slip material formed as described above is
The peeling layer of the adhesive part 4 is peeled off to expose the adhesive layer, and the vertical inner surface of the stepped bent part 1c of the hard substrate 1 is brought into close contact with the riser surface 10b of the stairs 10, as shown in FIG. First, the horizontal plate part 1a is placed on the tread of the stairs, and the inclined plate part 1b is placed on the stairs so that the end covering material 3 contacts the riser surface. When a person walks on the anti-slip material in this condition, the grooves in the horizontal covering portion 2a provide cushioning properties, and the bottom of the footwear is prevented from slipping by the uneven stripes. The bottom of the footwear is curved from the upper surface of the extended covering part 2b to the curved covering part 2c.
As you step on the side gradually, the curvature of this curved covering portion and the direction of movement of the footwear's treading force almost match, and the lower end of this curved covering portion is in step with the inclined plate portion 1b of the hard substrate on the extension of the curvature. Since it is joined to the corner between the shaped bent part 1c, the above-mentioned tread pressure is transmitted so as to be applied entirely to this corner, and this is the part that contacts the riser surface of the inclined plate part and the stepped bent part. The above-mentioned tread pressure is received smoothly, so that the extended sheathing portion and the curved sheathing portion are not deformed excessively, and no unreasonable shearing force is applied to their bases. In addition, when the anti-slip material is attached to the stairs in this way, the horizontal plate portion 1a of the hard substrate 1 is tightly attached to the tread surface 10a of the stairs by the adhesive portion 4, but the inclined plate portion 1b
Even if its lower end becomes separated from the riser surface 1b, the end covering material 3 provided on the lower end can eliminate any gap between it and the riser surface.

Effects of the invention As explained above, according to the invention, the curved covering part provided as a buffer part of the soft covering material has an approximately semicircular cross section at the front end of the extension covering part and the front face of the upper end of the inclined plate part. Since it is designed to protrude forward and create a large gap in the front and back directions, the cushioning function in the front and back direction is increased, and even if a person accidentally falls, the impact can be alleviated. At this time, since the upper surfaces of the extended covering part and the curved covering part are formed lower than the upper surface of the protrusions provided on the horizontal covering part, the toes of the foot or the corner of the heel of the shoe may get caught in this part. It is safe when going down the stairs.

Furthermore, since the curved covering part is connected to the corner where the hard substrate and the stepped bent part intersect on the extension in the curved direction, the base is not forced to deform unreasonably, and the As a result, it is possible to prevent this part from peeling off from the joint or cracking due to repeated fatigue at the end of the joint, and the curvature of the curved covering part is not forced to deform due to treading pressure, so the treading feeling can be improved. .

Also, if the lower end of the hard board does not come into close contact with the riser surface of the stairs and is installed with this part protruding forward, but you do not notice that it is protruding and you wipe it with a rag. The lower end of the sloping plate is integrally formed with a slightly thick soft end covering material that curves and protrudes downward and forward, so it will not cause injury even if your fingers or hands are hit or rubbed against it. Inconveniences such as severe pain can be avoided.
