BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a connecting tool used for assembling and connecting a flat structure having a frame and a pier or a net. The present invention relates to a connector used for manufacturing a body, a protective fence, a foldable partition, a book holder, a triangular corner shelf, and the like.

[0002]

2. Description of the Related Art In general, when manufacturing a cage made of wire mesh, a bar or the like is first welded to form a cubic frame, and then a wire mesh or a bar is fixed to the outer peripheral surface of the frame. Many methods have been adopted. Recently, a method of forming a rectangular frame to which a metal net or the like is attached first, and then welding the frame to assemble into a box shape from the viewpoint of increasing the efficiency of manufacturing the cage and the like has been proposed. Widely used. However, since the method of welding and assembling the frame body to which the above-described metal net or the like is attached into a box shape is extremely poor in welding workability,
There is a drawback in that the production efficiency of the cage cannot be greatly increased. In addition, the cage and the like manufactured by each of the above-mentioned construction methods,
Inevitably, the product becomes bulky, causing various problems in terms of storage and transportation of the product.

[0003] Also, in the construction work and road construction, etc.
By arranging flat frames with metal nets etc. in series and connecting the frames with a band or wire,
A protective fence is formed. However, the connection of the frames by means of a band or a wire is troublesome and unpleasant, and has a drawback in that, for example, when a passerby touches the body, the human body or clothing is damaged.

[0004] Further, a partition member for a large room, a shelf for a corner of a room, and the like are formed by connecting a frame body to which a metal net or the like is attached by a hinge or the like so as to be freely foldable. However, when the frames are connected by hinges or the like, each frame cannot be removed freely, which makes transport and storage when not in use extremely difficult, and it takes time to attach the hinge itself. There is a difficult point.

[0005]

[Problems to be Solved by the Invention] The present invention is based on a conventional structure such as a basket, a protective fence, a foldable partition, a corner shelf, a frame such as a book holder and a frame or a net. The above-mentioned problems in various products, namely, the connection and assembly by welding, are inferior in workability, so that it is difficult to improve the production efficiency, and the bulky products make it difficult to store and transport them. When assembled using gold or wire, the appearance of the finish is poor and it is easy to damage the human body and clothing. It is intended to solve problems such as excessive installation time, etc., and it is extremely easy to connect flat structures with a frame and a crosspiece or a net,
In addition to being able to be connected firmly and detachably, the crossing angle and connecting height at the time of connecting the structures can be set arbitrarily, and furthermore, it provides a new connecting tool excellent in terms of beauty and safety. It is.

[0006]

A frame 4 and a crosspiece or net 5 are provided.
In the connecting tool used for assembling the flat structure A having the structure, the connecting body 1 is made of an elastic synthetic resin, and the connecting body 1 is provided with the frame 4 of the structure A. The two frame fitting grooves 2 provided with an insertion opening 2a on the front surface for fitting the frame 2 are formed in parallel, and further, the cross section of the frame A of the structure A crosses the frame fitting groove 2. The basic structure of the present invention is that a cross member locking groove 3 for engaging the cross member 5a of the net body 5 is formed.

[0007]

The insertion opening 2a of the frame fitting groove 2 is pushed open by utilizing the elasticity of the connector body 1, and the frame 4 of the structure A is fitted into the fitting groove 2. Then, the pier or net 5 of both structures A
Of the horizontal member 5a and the horizontal member locking groove 3 of the connecting member main body 1, the two structures A are rotated in opposite directions to each other, and the back surface (rear surface) of the horizontal member locking groove 3 ) Is brought into contact with the cross member 5a. Thus, the two structures A are connected at a predetermined intersection angle α. That is, the frame 4 of both structures A is connected and supported by the fitting groove 2, and the height position and the cross angle α of both structures A are regulated by the cross member locking groove 3, respectively.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a connector showing a first embodiment of the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a front view thereof, and FIG.

In the drawings, reference numeral 1 denotes a connecting member main body, 2 denotes a frame fitting groove, and 3 denotes a cross member engaging groove. The connecting member main body 1 is made of a synthetic material having elasticity such as polyethylene, polypropylene or hard nylon. It is integrally molded in a form in which a short cylinder is almost halved by a resin material. The frame fitting groove 2 is for fitting the frame 4 of the structure A to be connected, has an inner diameter corresponding to the outer diameter of the frame 4, and The opening size of the front opening 2a is appropriately selected according to the elasticity of the synthetic resin material. In this embodiment, two frame fitting grooves 2 are vertically arranged on the front side of the connector body 1. Further, the cross member locking groove 3 is used to insert and lock the cross member 5a of the crosspiece 5 or the net member 5 of the structure A to be connected or the auxiliary cross member of the frame body 4. , The horizontal bar of the fence, the auxiliary horizontal member of the support frame 4 and the like are engaged in the locking groove 3.
In this embodiment, the cross member locking groove 3 is formed orthogonal to the frame fitting groove 2.

In the embodiment shown in FIGS. 1 to 4, the cut depth of the cross member locking groove 3 is slightly larger than the cut depth of the frame body fitting groove 2. However, as will be described later. The cutting depth of the cross member locking groove 3 is appropriately selected according to the connection cross angle α of the structure A to be connected and the mounting position of the cross member 5a with respect to the frame 4. Further, in this embodiment, the connecting member main body 1 is made of synthetic resin. However, if the frame 4 of the structure A is made of synthetic resin having elasticity, it may be made of metal. Furthermore, in this embodiment, one cross member locking groove 3 is formed in the center of the connecting member main body 1 so as to cross the fitting groove 2 in the horizontal direction. When 5a is disposed in an oblique direction, the cross member locking groove 3 is also formed in an oblique direction with a fixed inclination angle,
Further, it is needless to say that the cross member locking groove 3 may be formed in two steps as required.
