  The first contact part 11, the second contact part 12, the third contact part 13, and the connecting part 14 are integrally formed of a synthetic resin material. The material is not particularly limited, but for example, a thermoplastic elastomer, rubber, sponge material, or the like can be used.

The second contact portion 12 and the third contact portion 13 can expand the second contact portion 12 and the third contact portion 13 toward the outside of the corner guard 1 by applying an external force.
FIG. 3 shows a state where the second contact portion 12 and the third contact portion 13 are expanded. As shown in FIG. 3, the first contact part 11, the second contact part 12, and the third contact part 13 are connected to each other via a connection part 14.
The connecting portion 14 between the first contacting portion 11 and the second contacting portion 12 is formed so that the thickness of the intermediate portion between the first contacting portion 11 and the second contacting portion 12 is reduced. It inclines toward the outside of the corner guard 1 from the contact surface 11a and the second contact surface 12a. That is, the connecting portion 14 between the first contact portion 11 and the second contact portion 12 includes an inclined surface 14a on the first contact portion 11 side and an inclined surface 14b on the second contact portion 12 side. The cross section of each of the inclined surface 14a and the inclined surface 14b of the connecting portion 14 is substantially V-shaped.
Similarly, the connecting portion 14 between the first contact portion 11 and the third contact portion 13 is formed such that the thickness of the intermediate portion between the first contact portion 11 and the third contact portion 13 is reduced. In addition, it is inclined from the first contact surface 11a and the third contact surface 13a toward the outside of the corner guard 1. That is, the connecting portion 14 between the first contact portion 11 and the third contact portion 13 also includes the inclined surface 14a on the first contact portion 11 side and the inclined surface 14b on the third contact portion 13 side.

The inclined surface 15b is provided so as to incline in the direction and the second contact portion 12 direction.

  The inclined surfaces 14a and 14b of the connecting portion 14 between the first contact portion 11 and the second contact portion 12 or the third contact portion 13 are in contact with each other when no external force is applied to the corner guard 1. It is in contact. At this time, the first contact surface 11a, the second contact surface 12a, and the third contact surface 13a are in contact with the other two contact surfaces at substantially right angles. At this time, the inclined surface 15a of the second contact portion 12 and the inclined surface 15b of the third contact portion 13 are in a state of contacting each other.

  That is, the connecting portion 14 has elasticity. For example, a person can apply force by hand so that the second contact portion 12 or the third contact portion 13 of the corner guard 1 can be spread outward, so that the corner guard 1 can be spread outward. An elastic force is generated toward the inside of the guard 1 (the direction in which the second contact surface 12a or the third contact surface 13a is substantially perpendicular to the first contact surface 11a). Then, when the hand to which this force is applied is released, the corner guard 1 is closed inward by the elastic force, and the inclined surfaces 14a and 14b and the inclined surfaces 15a and 15b are brought back into contact.

  In the state where no external force is applied to the corner guard 1, the first contact surface 11, the second contact surface 12a of the first contact portion 11, the second contact portion 12, and the third contact portion 13 are provided. Alternatively, the surfaces opposite to the third contact surface 13a (the first outer surface 11b, the second outer surface 12b, and the third outer surface 13b (see FIG. 1)) are in contact with the other two outer surfaces at substantially right angles. Has become. Further, portions of the first outer surface 11b, the second outer surface 12b, and the third outer surface 13b that are in contact with the other two surfaces are connected to the other two surfaces so as to form a smooth curved surface.

A projecting portion 16 is provided at an intermediate portion of the inclined surface 15b of the third contact portion 13. The projecting portion 16 is provided so as to project from the third contact portion 13 toward the second contact portion 12 in the corner guard 1 in a state where no external force is applied. The thickness of the protruding portion 16 is the same as that of the second contact portion 12 and the third contact portion 13. Further, the tip portion of the protruding portion 16 has a shape bulging toward the surface direction of the second contact portion 12.
The protruding portion 16 is provided integrally with the third contact portion 13 using a synthetic resin material.

When the protrusion 16 is fitted into the notch 17, the inner surface and the outer surface of the corner guard 1 of the protrusion 16 are flush with the second contact surface 12a and the second outer surface 12b, respectively. Becomes

Next, a method of attaching the corner guard 1 to the attachment 2 according to the present embodiment will be described.
Here, as shown in FIG. 1, each of the three surfaces (first surface 3, second surface 4, and third surface 5) of the shelf (attachment 2) intersects the other two surfaces at a substantially right angle. The case of mounting on a corner formed by the method will be described as an example.

A double-sided adhesive tape 6 is provided on each of the first contact surface 11a, the second contact surface 12a, and the third contact surface 13a of the corner guard 1. In addition, a release paper is provided on each double-sided adhesive tape 6 so as to cover the adhesive surface, and adhesion to other objects is prevented.
Note that the double-sided adhesive tape 6 may be attached to the first contact surface 11a, the second contact surface 12a, the third contact surface 13a, or the like in advance in the manufacturing process of the corner guard 1, The person who attaches the guard 1 may attach it to the corner guard 1 or the attachment 2 at the time of attachment. Further, the corner guard 1 may be fixed to the attachment 2 with an adhesive, a nail, or the like.

The procedure for attaching the corner guard 1 to the shelf 2 according to the present embodiment will be described below.
First, the release paper provided on the double-sided adhesive tape 6 on the first contact surface 11a is peeled off.
Next, the first contact surface 11 a is attached to one of the three surfaces forming the corners of the shelf 2 (first surface 3) with the double-sided adhesive tape 6.
Next, the release paper provided on the double-sided adhesive tape 6 on the second contact surface 12a is peeled off.
Next, the second contact surface 12a is attached to one of the three surfaces (second surface 4) forming the corners of the shelf 2 with the double-sided adhesive tape 6.
Next, the release paper provided on the double-sided adhesive tape 6 on the third contact surface 13a is peeled off.
Next, the third contact surface 13 a is attached to one of the three surfaces (third surface 5) forming the corners of the shelf 2 with the double-sided adhesive tape 6.
Next, the protruding portion 16 is fitted into the cutout portion 17 and fitted.
Through the above procedure, the corner guard 1 is attached to the attachment 2.
The protrusion 16 may be fitted into the notch 17 at the same time that the third contact surface 13 a is attached to one of the three surfaces forming the corners of the shelf 2.

Note that, instead of the first contact surface 11a, the second contact surface 12a or the third contact surface 13a may be attached first. In this case, it is desirable to attach the first contact surface 11a second. Further, in this case, the fitting of the protruding portion 16 into the cutout portion 17 may be performed simultaneously with the attachment of the third contact surface, or may be performed after the attachment of the third contact surface. Good.
Alternatively, any one of the first contact surface 11a, the second contact surface 12a, and the third contact surface 13a may be attached to the object 2 with the double-sided adhesive tape 6. Even in this case, since the corner guard 1 can be prevented from being unfolded by fitting the protruding portion 16 with the notch portion 17, the corner guard 1 can be securely attached to the object 2. Becomes

In the corner guard having such a configuration, the second contact portion 12 and the third contact portion 13 can be separately bent with respect to the first contact portion 11, respectively. Therefore, after any one of the first contact portion 11, the second contact portion 12, or the third contact portion 13 is adhered and fixed to the attachment 2 as in the above-described attachment procedure. , And the other two can be sequentially adhered and fixed.
In the conventional corner guard, since one of the first contact portion 11, the second contact portion 12, and the third contact portion 13 is fixed to the other two, the first contact surface 11a, When the double-sided adhesive tape 6 is provided on a plurality of the second contact surface 12a and the third contact surface 13a, the three contact surfaces are simultaneously attached to the object 2 when the corner guard 1 is attached. Need to be installed. However, when actually trying to do this, it is very difficult to accurately attach it to the position where it is to be attached, because one of the abutting surfaces sticks first.
According to the corner guard of the present embodiment, only one of the first contact portion 11, the second contact portion 12, and the third contact portion 13 can be bonded first. Become. In addition, since the second abutment portion 12 and the third abutment portion 13 can be developed, it is possible to visually confirm the portion where the corner guard 1 and the attachment 2 are bonded from various directions. Becomes possible.
Therefore, the corner guard 1 can be easily and accurately attached to the attachment 2.

  Also, the corner of the object 2 to which the corner guard 1 is to be attached is not formed from three surfaces that intersect at a substantially right angle, but has a larger or smaller angle, or has four or more surfaces. The corner guard 1 can be attached even when the corner is formed from the corner.

  Further, since the projection 16 and the cutout 17 are provided, the second contact 12 and the third contact 13 are connected by fitting the protrusion 16 and the cutout 17. can do. When the second contact portion 12 and the third contact portion 13 are not connected to each other, the second contact portion 12 and the third contact portion 13 can move independently of each other. When an external force is applied to the corner guard 1 in a state in which the adhesive is fixed, the force may concentrate on a part of the adhesive part and the like and the adhesive part may come off. By connecting the second contact portion 12 and the third contact portion 13 by fitting the protruding portion 16 and the notch portion 17, the force can be dispersed, and the adhesive portion is prevented from peeling. be able to. In addition, since the second contact portion 12 and the third contact portion 13 are connected to each other, the movement of each other is restricted, so that the first contact surface 11a, the second contact surface 12a, or the third contact surface 12a. The corner guard 1 can be attached to the object 2 only by bonding one of the surfaces 13 a to the object 2.

Further, in a state where no external force is applied, the first contact surface 11a, the second contact surface 12a, and the third contact surface 13a are respectively in contact with the other two surfaces at substantially right angles, and The surface is provided so as to face the inside of the corner guard 1. Therefore, when the corner guard 1 is attached to the attachment 2, unnecessary elastic force is generated in the corner guard 1, and it is possible to prevent the bonded portion from being peeled off.
Note that the second contact surface 12a and the third contact surface 13a may be formed so as to be inclined inward of the corner guard 1 from the first contact surface 11a side toward the opposite side. By doing so, the corner guard 1 can be brought into closer contact with the mounted object.
In a state where no external force is applied, for example, by making the connecting portion 14 or the like having a small elastic force, the second contact surface 12a and the third contact surface 13a are reversed from the first contact surface side. The corner guard 1 may be formed so as to be inclined outward toward the side. By doing so, the corner guard 1 can be easily deployed, so that the corner guard 1 can be easily attached to the object 2.

  The shape of the first contact portion 11, the second contact portion 12, or the third contact portion 13 is not limited to the above shape. The first contact portion 11 may have a substantially rectangular plate shape, the second contact portion 12 and the third contact portion 13 may have a triangular plate shape, or other plate shapes. There may be. For example, a form in which the first contact part 11 and the second contact part 12 are interchanged in the present embodiment is also conceivable. Further, the corner guard 1 is not limited to a plate shape, and a part of the corner guard 1 may be expanded into a spherical shape or the like, or may have a three-dimensional shape imitating a character or the like.

  Note that a plurality of protrusions 16 and notches 17 may be provided, respectively. Further, each of the second contact portion 12 and the third contact portion 13 may be provided with one protrusion 16 and one notch 17, for example. The shape of the protruding portion 16 and the cutout portion 17 is not particularly limited as long as the shape can connect the second contact portion 12 and the third contact portion 13.

  The surface shape of the first contact surface 11a, the second contact surface 12a, or the third contact surface 13a is not limited to a plane. For example, the surface may be a curved surface or the like, or the surface may be uneven. In the case of a curved surface, the corner guard 1 suitable for the case where the mounted object 2 has a curved surface can be obtained. In addition, when the surface has irregularities, it is possible to prevent the corner guard 1 from shifting after being attached.

  Note that only one of the second contact portion 12 and the third contact portion 13 may be connected to the first contact portion 11 via the connection portion 14. Even with such a configuration, only the second contact surface 12a or the third contact surface 13a can be first adhered to the attachment 2 and fixed.

  Note that the first contact portion 11, the second contact portion 12, the third contact portion 13, and the connecting portion 14 may not be integrally formed of the same material. The connecting portion 14 is formed of a material that can easily bend or expand the second contact portion 12 and the third contact portion 13, and the first contact portion 11, the second contact portion 12, or the third contact portion The contact portion 13 may be formed of a hard material such as metal or wood to protect the attachment 2. Further, the connecting portion 14 may have another shape that allows the second contact portion 12 and the third contact portion 13 to bend or extend easily. For example, instead of being connected by the connecting portion 14 over one side as in the present embodiment, a form in which only a part of one side is connected may be used.

  In addition, the positional relationship between the second contact portion 12 and the third contact portion 13 is not limited to that of the present embodiment. That is, in the present embodiment, as shown in FIG. 1, when the first contact portion 11 is turned upward and the corner guard 1 is viewed from the outside, the second contact portion 12 is on the left side and the third contact portion 11 is on the left side. The contact portion 13 is located on the right side, but the second contact portion 12 may be located on the right side and the third contact portion 13 may be located on the left side.
