Description

[Detailed description of the invention] This invention is for stairs that is attached to the tread surface of stairs to prevent slipping, and also has good drainage so that water does not accumulate on the top surface, and integrates the anti-slip ridge and the step flat part. Regarding blocks.

In the past, there have been examples of stair blocks in which long anti-slip protrusions are lined up horizontally on the top of stairs in station premises, etc., but the protrusions near the corners, where feet are frequently stepped on, are particularly prone to wear. Since the stair block is easily attached, it requires time and effort to replace it at an early stage, and since the upper surface of the stair block is substantially horizontal and has no slope, water tends to accumulate, often causing walking problems.

The present invention eliminates such drawbacks, and the embodiment thereof will be described in detail below.
On the top surface, from the side that will be the tip corner side to the side that will be the base end side when attached to the top surface of the stairs, there is a long protrusion 2 with the same length as the width of the board 1, and the long protrusion 2. Same length as 2 and long protrusion 2
Several long protrusions 3 formed to a width of approximately l...
are arranged in parallel rows near the sides with a narrow interval between them, and
Several elongated protrusions 4 are formed approximately in the center of the elongated protrusions 3 and have the same length and width, and are arranged in parallel rows with very narrow intervals, Several long protrusions 4', which are slightly taller than the long protrusions 4, are located between the long protrusions 4 and the long protrusions 3.
... are arranged horizontally in parallel with very narrow intervals, and the substrate 1 surface between the long protrusions 2 and 3 and the substrate 1 on the side where the long protrusions 2 are provided. Caution signs are attached to each of the recessed side surfaces 1' of the board 1, but the most distinctive feature of the present invention is that the long protrusion 4' is longer than the long protrusion 4 provided in the center of the board 1. It is taller and has long protrusions 2 and 3.
are formed taller than the long protrusions 4', and the tangents X touching the top surfaces of the long protrusions 2, 3, 4' and the long protrusions 4
The height of the tread is gradually increased toward the corner of the tread so as to form an angle with respect to the upper surface of the tread.

The periphery of each long ridge is missing and rounded.

As another example, as shown in FIG. 7, if a large number of three long protruding strips 5... are provided on the bottom surface of the substrate 1, they will slip by turning them upside down and attaching them. It can be a block that also serves as a stop.

Since the present invention is constructed in this way, use adhesive or the like on the staircase surface so that the tangent line X connecting the top surface of each long protrusion is horizontal, and the long protrusion 2 is placed on the tip corner side of the staircase. If the board 1 is attached integrally in the same position, the top surface of the board 1 will form a slight downward slope toward the tip corner of the stairs, so there is no risk of water accumulating on the top surface of the board 1, and walking obstruction will be avoided. Does not cause

In addition, long protrusions 2 and 3 are provided on the tip side of the stairs, where feet come into contact most often when going up and down the stairs and have a high degree of wear.
・ are raised and protruding from each other to withstand long-term use.
Since the space between the and long protrusions 2 and the side surface 1' of the base plate 1 are each colored yellow, even a visually impaired person can clearly see the tip of the stairs, thereby preventing accidents such as tripping.

As described above, the present invention has a simple structure, is easy to manufacture, and has a long service life.

[Scope of utility model registration request] This stair block is formed by forming an angle between the upper surface of a rectangular base plate and tangents that touch the top surfaces of multiple anti-slip ridges protruding from the upper surface, gradually increasing the height toward the corners of the tread.
