[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner cushion, and more particularly, when adjusting the length, the cut portion does not open, and the corner cushion does not expand in the summer, which results in a strip-shaped front surface material or a strip-shaped back surface material. The present invention relates to a corner cushion capable of preventing breakage and preventing wrinkles and slack from occurring in the belt-shaped back surface material and the adhesive material when it is bent, thereby facilitating easy and reliable attachment to the corner portion.

[0002]

2. Description of the Related Art Corners of construction sites and corners of buildings are dangerous when people or objects collide. For this reason, a cushioning material is often attached to the same corner portion in order to reduce the shock at the time of a collision.
In recent years, in addition to the cushion effect, a corner cushion (11) as shown in FIGS. 5 and 6 has been proposed as a device that can appeal the presence of a corner portion to call attention. This corner cushion (11) is formed by a strip-shaped surface material (12) and a strip-shaped back surface material (13) made of a water-resistant sheet material, and a closure formed between the strip-shaped surface material (12) and the strip-shaped back surface material (13). Cushion material (14) filled in the enclosed space and strip-shaped surface material (12)
The striped back surface material (13) has an oblique stripe pattern (15) formed on the outer surface thereof and an adhesive material (16) applied to the outer surface of the strip-shaped back surface material (13), and forms a strip shape as a whole. An open-cell type sponge is used for the cushion material (14).

The corner cushion (11) is bent along the corner and is attached to the corner with an adhesive material (16). This corner cushion (1
1) has a cushioning material (14) inside and also has a diagonal stripe pattern (15) on the surface, so that it alerts the surrounding people and shocks when a person or object collides. It was an excellent safety tool for corners.

[0004]

However, the above-mentioned corner cushion (11) has the following problems. That is, this corner cushion (1
Since 1) had a uniform cross-section structure with no breaks in the longitudinal direction, when cut according to the length of the corner, the cut part opened openly, and rainwater invaded through the opening during rainy weather. It was In addition, the cushion material (14) may fall out from the opening. Furthermore, since the continuous foam type sponge is used for the cushion material (14), rainwater that has entered the corner cushion (11) permeates the entire cushion material (14), and the corner cushion (11) is submerged. There was an occasion. When this happens, the corner cushion (1
There is a risk that the water will always drop from 1) and it will be very unattractive, and that it will not be able to sufficiently absorb the shock when a person or object collides.

Further, since the cushion material (14) is filled in the closed space formed between the strip-shaped surface material (12) and the strip-shaped back surface material (13), the closed space is provided in summer. The air inside expands and the corner cushion (1
1) The whole expands, and the belt-like surface material (12) and the belt-like backing material (13) may be broken by a shock when a person or an object collides. In this case, in rainy weather, rainwater may infiltrate from the torn portion, resulting in the above-mentioned water immersion state.

Further, in this corner cushion (11), the cushion material (14) is a strip-shaped surface material (12).
Since it was not adhered to the belt-shaped backing material (13),
When the cut is performed according to the length of the corner portion, the cushion material (14) may fall out from the opening portion due to the cut, and it may take time and effort to attach the cushion material (14) to the corner portion.

Further, in this corner cushion (11), when it is bent in the longitudinal direction to be attached to a corner portion, the strip-shaped backing material (13) is a strip-shaped surface material (12).
On the other hand, the radius of curvature is reduced by the thickness of the cushion material (14). For this reason, wrinkles and slack have occurred in the strip-shaped back surface material (13) and the adhesive material (16) applied to this. In this case, the adhesive material (16) due to wrinkles and slack
They stick to each other, which hinders the installation work in the corners, and corner cushions (11) to the corners.
It was difficult to bring them into close contact.

The present invention has been made in view of such a situation, and when the length is adjusted, the cut portion does not open even if it is cut, and the corner cushion does not expand in the summer. It prevents the backside material and the band-shaped backing material from breaking, and even when rainwater enters the inside, the rainwater does not penetrate into the cushion material, and when it is bent, the band-shaped backing material and the adhesive material do not wrinkle or sag. An object of the present invention is to provide a corner cushion that can be easily and surely attached to a corner portion.
