Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a corner guard that is attached to a corner of a wall surface and protects the wall surface or pedestrians from impact. It's all about good corner guards.

[Conventional technology]

Conventionally, as shown in FIG. 3, this type of corner guard is made of a substrate 3 fixed along a corner of a wall surface 1 and an elastic material such as a hard resin, and there is a gap between the substrate 3 and the substrate 3. It consists of a cover 5 that is attached with a gap 4 and a cushion material 6 that is attached to the corner portion 2, and the shock applied to the cover 5 is absorbed by the deformation of the cover 5 and the cushion material 6. The following was proposed.

In such a case, the cover 5 is attached to the board 3 by bending the cover 5 itself so that, for example, the engaging parts 5a, 5a formed at both ends of the cover 5 are connected to the engaging receiving part 3a of the board 3. , 3a.

[Problem that the invention seeks to solve]

In this way, by bending the cover 5 itself, the engaging portion 5
When a is engaged with the engagement receiving part 3a, at a certain stage it enters the board 3 side from the position when the cover 5 was installed, which causes the cushion 6 to bend, but in the conventional example, the cushion 6 If the hardness is high, the cushion 6 will not bend easily, making it difficult to attach the cover 5. Conversely, if the hardness is low, the cushioning effect against impact cannot be exhibited.

The present invention has been made in response to these circumstances, and provides a corner guard that allows the cover 5 to be easily attached and that maintains the necessary flexibility and exhibits a cushioning effect after being attached. The purpose is to

[Means for solving problems]

Hereinafter, means for achieving the above object will be explained based on FIG. 1 corresponding to the embodiment. In addition to actively wearing it,
A gap 4 formed between the substrate 3 and the cover 5
This invention relates to an improvement of a corner guard that is constructed by mounting a cushion material 6 inside the corner guard. It is mounted along the substrate 3 at the portion 7 .

From the supporting part 7 of the cushion material 6, the outer side, that is, the supporting part 7 corresponds to the substrate 3.
A large number of protrusions 8 perpendicular to the upper plane,
8... is provided protrudingly.

[Effect]

Generally, in order to install this type of corner guard, first, the board 3 with the cushion material 6 attached is fixed to the corner part 2 of the wall surface 1, and then the cover 5 is elastically attached to the board 3. However, when attaching the cover 5 to the board 3, it is necessary to bend the cushion material 6, and the cushion material 6 must have the required deflection reaction force after the cover 5 is attached, and be It is desirable that the bending reaction force be as small as possible during installation.

On the other hand, when observing the deflection of the cushion material 6 in detail, the direction of deflection when the cover 5 is attached and the direction of deflection when acting as a shock absorbing material after attachment are different. (See FIG. 2), it can be seen that in the latter case, the cushion material 6 is deflected in the direction perpendicular to the wall surface 1.

The present invention has been made with attention to such points, and the cushion material 6 is provided with a large number of protrusions 8, 8... This is an attempt to obtain a corner guard which is formed by protrudingly provided with a cover 5 and has the required impact absorption performance while being easy to attach the cover 5 to.

That is, the load in the direction A in FIG. 1 acts as a buckling load on the protrusion 8 of the cushion material 6 of the present invention, and as a result, the deflection reduces the reaction force to a sufficient degree as a buffer against the impact force. On the other hand, the load in the direction B in FIG. 2 acts as a bending load, making deformation relatively easy and preventing large resistance from occurring when the cover 5 is attached.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, an embodiment of the invention is shown.

In this embodiment, the substrate 3 is a long material bent into a substantially L-shaped cross section to correspond to the corner portion 2 of the wall surface 1, and is extended over substantially the entire length of the wall surface 1 in the height direction by an anchor 9. It is fixed.

This substrate 3 has an engagement receiving part 3a formed by bending both ends thereof outward in a semicircular arc shape, and engages an engagement part 5a of a cover 5 made of an elastic material such as a hard synthetic resin. The cover 5 can be attached elastically, and attachment grooves 3b are formed near the corners of the cover 5, so that the support portion 7 of the cushion material 6 can be supported.

The cushion material 6 is made of a flexible material such as vinyl chloride or rubber. 3b, 3
b and is configured to be attached over the entire length of the board 3.

Further, a circular concave portion 7b is formed at the corner of the support portion 7 of the cushion material 6, and is engaged with a bulge portion 3c protruding from a corresponding portion of the substrate 3. To prevent displacement, the protrusions 8 in this region protrude radially from the center.

Next, the procedure for attaching the corner guard of this embodiment to the corner portion 2 of the wall surface 1 will be explained. First, after fixing the board 3 to the corner portion 2 of the wall surface 1 from the ceiling to the vicinity of the floor, Both ends 7b, 7b of the support part 7 are engaged with the mounting groove 3b, and the cushion material 6 is
Attach.

Next, one engaging portion 5a of the cover 5 is attached to the substrate 3.
While deforming the entire cover 5, the other engaging portion 5a is connected to the substrate 3.
The cover 5 is elastically attached onto the substrate 3 by engaging with the engagement receiving portion 3a of the cover 5.

At this time, the cushion material 6 is easily bent as shown in FIG. 2 as the cover 5 moves laterally, so the cover 5 can be easily attached.

In the above explanation, the case where the board 3 is fixed to the corner part 2 of the wall surface 1 from near the ceiling to near the floor has been explained, but the present invention is not limited to this, and the piece-like board can be fixed to the appropriate height. It goes without saying that a plurality of cushion members 6 may be fixed to the substrate 3, and furthermore, the cushion members 6 may be attached to areas other than the corners of the substrate 3.

〔Effect of the invention〕

As is clear from the above description, according to the corner guard according to the present invention, the cushion material is formed with a large number of protrusions protruding outward from the support portion located along the base plate. The material easily bends when the cover is bent and attached, and when the front of the cover receives an impact, the required bending reaction force can be obtained.

Therefore, it is possible to obtain a corner guard whose cover is easy to attach and which has excellent cushioning performance.
