It is impossible to fix it, and it is necessary to use the screw 15 to fix it, and for that purpose, the screw insertion hole 6 is also required, which makes drilling the hole troublesome and the work of installing the screw 15 is also troublesome, resulting in poor workability. .

Therefore, the purpose of the present invention is to provide a connecting tool suitable for connecting greenhouse door frames, frames constituting a greenhouse, etc., which does not require hole drilling and can be easily and quickly attached and detached. be.

[Means to solve the problem]

In order to achieve the above object, the structure of the connector of the present invention is as follows: The device is characterized by comprising a pair of supporting pieces, and a hook portion provided at the tip of each supporting piece and extending outward in parallel with the main body.

Further, in order to facilitate attachment of the support piece, a tapered surface is formed on the back surface of the hook portion.

[Effect]

When joining two frames in orthogonal directions,
When the connector is inserted diagonally into the slit of one frame and the main body is rotated, the hook portion is hooked on the lip of the frame, and the connector is fixed to one frame using only the support piece and the hook.

The tapered surface on the back of the hook guides the oblique insertion of the support piece and the hook into the slit.

〔Example〕

Embodiments of the present invention will be described below based on FIGS. 1 to 5.

FIG. 1 is a perspective view showing a connector according to an embodiment of the present invention.

The connector 16 includes a plate-like main body 17, a pair of clamping pieces 3, 3 standing up on both sides of the end of the main body 17, and a main body 17.
A pair of support pieces 18, 18 stand up in the same direction as the clamping pieces 3, 3 on both sides of the other end, and hook parts 19, 19 are provided at the tips of each support piece and extend outward in parallel with the main body 17. A bolt insertion hole 5 is formed in the main body 17. The main body 17 is provided with one or more auxiliary screw insertion holes 6.

A tapered surface 2 is provided on the back surface of the hook portion 19 in an oblique direction.
0,20 is formed, but this tapered surface 2
0 and 20 can be used even without them.

FIG. 3 shows a door D in a greenhouse C assembled using the connector 16 of the present invention.

The door D is assembled with frames of the same structure, and the four frames 7 constitute a rectangular outer frame A, and the outer frame A
A plurality of frames 7 are constructed in the middle to form a horizontal frame B, and the horizontal frame B, which is perpendicular to the outer frame A, is connected by a connector 16.

Each frame body 7 constituting the outer frame A and the horizontal frame B has a narrow opening dovetail groove 8 for fixing a vinyl sheet or the like on one side, and a slit 9 for inserting a fastener on the other side. It is formed between lips 11, 11 formed by bending the ends of both sides 10, 10, and defines a hollow part 21 inside, which opens outward through the slit 9.

The end surface of the frame body 7 on the side of the horizontal frame B abuts and is perpendicular to the side surface of the frame body 7 on the side of the outer frame A. two frames 7,
7 are connected via the connector 16 in the following manner.

First, as shown in FIG. 4, the frame body 7 on the outer frame A side
The hook part 19 and support piece 18 are inserted diagonally toward the hollow part 21 through the slit 9, and then the hook part 19 is hooked onto the lip 11, and the main body 17 is rotated in the direction of the arrow Y using this as a fulcrum. Fold it down, insert the frame body 7 on the horizontal frame B side into the clamping pieces 3, 3, and clamp it. When inserting the hook part 19,
The tapered surface 20 is used as a chamfer to guide the movement of the hook portion 19 and to prevent the end of the support piece 18 from coming into contact with the edge of the slit 9.

However, if the width of the slit 9 is wider than the width of the support piece 18, it can be used without this tapered surface 20.

The hook part 12a of the stopper 12 is inserted into the slit 9 and the hollow part 21 in the frame 7 on the side of the horizontal frame B, and is hooked, and the bolt 13 of the stopper 12 is connected to the connector 1.
