Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corner connector for connecting end portions of edge members such as a skirting board, a peripheral edge, and a parting at corner portions such as a corner of a room and a corner of a room.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 6, a corner connector (b) for connecting the ends of the edge member (a), which is a skirting board, is known in the corner portion of the room. In this case, the edge member (a) is fixed to the corner portion between the wall surface (c) and the floor surface (d) by means such as adhesion or nailing, and the projected corner portion of the wall surface (c) ( (E) It is mounted on both sides with a margin between each other. Further, the corner connecting tool (b) is formed by arranging mold members having a substantially L-shaped cross section along the outer shape of the edge member (a) at a substantially right angle and integrally formed with a synthetic resin. It is a thing. The corner connecting tool (b) is fitted and nailed between the ends of both edge members (a) and fixed, and the ends of both edge members (a) to be connected are It is housed and hidden in a space (f) behind the corner connector (b).

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, a void (f) is generated in the middle backside of the corner connecting device (b) in a state of being fitted over the end portions of both edge members (a), The corner portion of the corner-connecting tool (b) was likely to be dented and deformed by an external force.

The present invention has been devised to solve the above-mentioned problems in the prior art. That is, the problem is that it is hard to be dented and deformed by an external force and is thick on the surface of the edge member. It is an object of the present invention to provide a corner connector which is connected neatly so as not to project.

[0005]

[Means for Solving the Problems]

 In the corner connector of the present invention, a mold having a cross-sectional shape along the outer shape of an edge member to be connected is continuously formed at a substantially right angle to form a connector main body, and the connector main body is provided on the back side of the connector main body. The reinforcing material is lined, and recesses where the reinforcing material is not lined are provided at both end portions of the connector main body, and this configuration solves the above problem.

[0006]

[Action]

 In the corner connector of the present invention, a mold body having a cross-sectional shape along the outer shape of an edge member to be connected is continuously provided at a substantially right angle to form a connector body, and the back side of the connector body is formed. Since the reinforcing material is lined on the surface of the connector, it is strong and hard to be deformed even when external force is applied to the surface of the connector body.In addition, the reinforcing material is not lined on both ends of the connector body. Since the location is provided, the end portion of the edge member is housed in the recess, and the connector body is connected in a good appearance so as not to project thickly on the surface of the edge member.

[0007]

【Example】

 The corner connecting tool shown in FIGS. 1, 2 and 3 is an embodiment of the present invention, in which mold members having a cross-sectional shape along the outer shape of the edge member 1 to be connected are continuously provided at a substantially right angle. The connector body 2 is formed, the reinforcing material 3 is lined on the back side of the connector body 2, and the recesses 4 in which the reinforcing material 3 is not lined are provided at both ends of the connector body 2. .

The edge member 1 is a skirting board, and a synthetic resin sheet 6 is adhered and formed on the surface of a wood material 5, and a concave groove portion 7 is provided in the middle of the surface. Further, the edge member 1 is cut to an appropriate length dimension and fixed to a corner portion between the wall surface 8 and the floor surface 9 by a method such as bonding or nailing, and the edge portion 10 of the wall surface 8 is fixed. It is mounted on both sides with an appropriate distance from each other.

The connector body 2 is formed by bending a synthetic resin-coated steel plate obtained by coating the surface of a steel plate core material 11 with a synthetic resin layer 12, and A groove-shaped portion 13 corresponding to the concave groove portion 7 is provided in the middle portion thereof.

On the back side of the connector body 2, a reinforcing material 3 is lined, leaving recesses 4 at both ends thereof. The reinforcing material 3 is made of a synthetic resin foam such as a vinyl chloride resin foam or a urethane resin foam, and is integrally molded on the back side of the connector main body 2. Further, the reinforcing member 3 and the connector main body 2 are formed so that the total thickness thereof is the same as the thickness of the entire corner connector.

Further, the recesses 4 provided at both end portions of the connector main body 2 may be formed in such a size that the end portions of the edge member 1 to be connected can be accommodated and the expansion / contraction deformation thereof can be absorbed. The same shape is formed at both end portions of the connector main body 2. Further, the end portion of the edge member 1 housed in the recess 4 is fitted in a state of being elastically contacted with the end surface of the reinforcing member 3.

In the corner connector of the embodiment, an adhesive is applied to the back surface of the reinforcing member 3 and the inner surfaces of the both recesses 4, and the adhesive is fixed to the wall surface 8 and the front surfaces of both edge members 1 by the adhesive material. In this case, a double-sided tape may be attached in advance to the inner surface of the recess 4 or the like, and it may be fixed by nailing.

Therefore, in the corner connector of the embodiment, the connector main body 2 is formed by connecting the mold members having the cross-sectional shape along the outer shape of the edge member 1 to be connected, at a substantially right angle. Since the reinforcing material 3 is lined on the back side of the connector body 2, the connector body 2 is hard to be dented and strong even if an external force is applied to a surface corner portion of the connector body 2. Moreover, since the recesses 4 in which the reinforcing material 3 is not lined are provided at both end portions of the connector main body 2, the end portions of the edge member 1 are housed in the recesses 4 and the surface of the edge member 1 is accommodated. The connector body 2 is connected in a good appearance so that the connector body 2 does not project thickly. Further, in this embodiment, since the end of the edge member 1 is fitted and held in the recess 4, the synthetic resin sheet 6 on the surface of the edge member 1 is prevented from peeling off. .

The corner connecting device of the present invention may be the one as shown in FIGS. 4 and 5. That is, in the corner connecting device of the embodiment, the edge member 1 is a rounded edge, is made of synthetic resin foam and is integrally formed by extrusion molding, and is formed between the wall surface 8 and the ceiling surface 14. Are fixed to the corner portions of the wall surface 8 and are attached to both sides of the corner portion 15 of the wall surface 8 at appropriate intervals. The connector body 2 is integrally molded by injection molding with a synthetic resin, and two synthetic resin foams are adhered to the back side of the connector body 2 to form a lining material 3 on the back side. Therefore, there is a substantially V-shaped missing portion in the middle of the reinforcing member 3, but this missing portion does not hinder the reinforcement on the surface side, It serves as an escape space for the entry corner 15.

[0015]

[Effect of the device]

 As described above, in the corner connector of the present invention, since the reinforcing material is lined on the back side of the connector body, even if external force is applied to the surface of the connector body, the connector body is not easily dented and is strong. In addition, since the recesses not lined with the reinforcing material are provided at both end portions of the connector main body, the end portions of the edge members are housed in the recesses and are connected in a good appearance.
