DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner protecting member for protecting a corner portion of a pillar, a leg, or the like constituting a desired structure, which is susceptible to an external impact.

[0002]

2. Description of the Related Art Conventionally, in a column or a leg, a protection member made of a resilient material or a material capable of relieving a shock is applied to a portion which is likely to be damaged by an external impact with an adhesive, an adhesive tape or the like. Was attached by the material which has.

[0003]

In the case of the above-mentioned prior art, when the protective member is glued and fixed with an adhesive or a tape, it is difficult to peel off the protective member again, and the adhesive and the like can be completely removed. Did not. further,
Once peeled, there is a problem that the coating on the surfaces of the pillars and legs or a part of the film is peeled off, and the appearance becomes unsightly.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a corner protection member which can be freely attached to and detached from a corner portion and which reliably protects the corner from impact.

[0005]

SUMMARY OF THE INVENTION A corner protection member according to the present invention includes a columnar member such as a pillar or a leg having a concave portion at or near a corner portion such as a corner portion, a protective member having a convex portion and having elasticity. A corner protection member comprising a member, wherein a protrusion of the protection member is engaged with a recess of the columnar member, and a shock applied to a corner of the columnar member is buffered by the protection member.

The protective member is made of shock absorbing rubber having a constant cross-sectional shape. The columnar member has a constant cross-sectional shape, and the concave portion is a T-shaped groove having a space of a predetermined size inside.

Further, the convex portion has a triangular shape which becomes thinner toward the tip portion, has a contact surface wider than the opening of the concave portion, and is formed narrower than the contact surface.
A corner protection member, comprising a support portion that can be inserted into the opening of the groove, wherein the contact surface of the projection contacts the inner surface of the opening of the recess when the projection is engaged with the recess.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, in which a columnar member 14 having two T-groove-shaped concave portions 12 at a corner portion 10 and a protection member having two convex portions 16 inserted into the concave portions 12. The member 18 is shown.

As shown in FIG. 2, the columnar member 14 has a substantially L-shape in which the corner portion 10 is curved in an arc shape.
An opening edge 20 having a predetermined width and thickness, a width larger than the width between the opening edges 20 and a space 22 having a predetermined height are provided inside. The two concave portions 12 are separated by a side wall portion 24 having a predetermined thickness, and the columnar member 14 is an extruded member having a constant cross section.

On the inner and outer side surfaces of the columnar member 14, T-grooves 25 through which nuts can be inserted are formed, and the L-shaped inner side surfaces are positioned at right angles to each other. In addition, an arc-shaped groove 27 is formed at the L-shaped inner corner, and the inside of the columnar member 14 is formed hollow.

The protective member 18 is made of a resin such as rubber which has elasticity and has a function of absorbing and buffering an external impact, and has a constant cross-sectional shape. As shown in FIG. 3, both ends 18 a of the protective member 18 are formed in a shape that is slightly curved inward from the curved surface of the corner 10.

The protective member 18 has a convex portion 16 at a position where it can be inserted into each concave portion 12 when it is attached to the corner portion 10. The convex portion 16 has a height of approximately the same as or slightly smaller than the thickness of the opening edge portion 20 of the concave portion 12 and a width between the opening edge portions 20. And a supporting portion 28 having a predetermined width.

The columnar member 14 and the protective member 1 of this embodiment
8 is inserted into the space 22 of the concave portion 12 by inserting the fixing portion 26 of the convex portion 16, and the contact surface 30 of the fixing portion 26 is engaged with the engaging surface 32 which is the back surface of the opening edge 20 of the concave portion 12. At the same time, the support portion 28 of the convex portion 16 is
It is fitted and fixed between 0.

At this time, each contact surface 30 of the two convex portions 16
Are engaged with the engaging surfaces 32 of the respective concave portions 12 and the both end portions 18a of the protective member 18 are curved inward, so that the concave portions 12 and the convex portions 16 are securely engaged with each other. Once the protection member 18 is once attached to the columnar member 14, it does not easily come off. Further, the protection member 18 absorbs an external impact, thereby preventing the columnar member 14 from being damaged.

Since the protective member 18 is made of elastic rubber, the protective member 18 can be removed by pulling it out of the concave portion 12 of the columnar member 14, and can be attached again.

Next, a second embodiment of the present invention will be described with reference to FIGS. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted. The corner protection member of this embodiment includes two corner portions 10.
A columnar member 32 having one T-groove-shaped recess 12 each;
2 shows two protection members 34 each having one projection 16 inserted into the recess 12.

As shown in FIGS. 4 and 5, the columnar member 32 is substantially L-shaped having two corner portions 10, and each corner portion 10 has one recess 12. An opening edge 20 having a predetermined width and thickness is provided, and a space 22 having a width larger than the width between the opening edges 20 and surrounded by a side wall 24.

The protection member 34 is made of a resin such as rubber which has elasticity and has a function of absorbing and buffering an externally applied impact, and as shown in FIG. One unit 16 is provided. The convex portion 16 is provided on the protection member 3.
4, the protection member 34 is curved in the direction of the convex portion 16 and has a shape corresponding to the curve of the corner portion 10. The convex portion 16 includes a fixed portion 26 and a support portion 28 similar to those in the above-described embodiment.

The columnar member 32 and the protective member 3 of this embodiment
The mounting method of 4 is such that the protrusion 16 of each protection member 34 is inserted into each recess 12, and the contact surface 30 of the fixing portion 26 and the engagement surface 32 of the recess 12 are engaged. The portion 28 is fitted and fixed to the opening edge 20 of the recess 12.

Further, the protective member 34 can be easily removed by pulling out the protective member 34 from the columnar member 32, and can be attached again in the same manner as described above.

According to the corner protection member of this embodiment, the protection member 34 is attached to the columnar member 32 having a plurality of corner portions 10 having one recess 12 and having different distances between the corner portions 10, or It can be attached only to a predetermined corner portion 10.

The corner protection member of the present invention is not limited to the above embodiment, and the protection member may be any material that absorbs external impact and has elasticity.
The length may be about the same as the columnar member, or may be a predetermined length, and can be appropriately selected. The material forming the columnar member and the protective member is appropriately selected according to the application.

[0023]

The corner protecting member of the present invention has a simple shape, allows the columnar member to be freely attached to and detached from the corner portion, and can surely protect the corner portion from external impact. In addition, by providing the engagement surface in each of the convex portion and the concave portion of the corner portion of the protection member, the protection member can be more firmly fixed to the columnar member.
