[The problem that the idea aims to solve]

However, the frame connector C has a supporting portion 12.
Cut slits 13 are formed on the left and right sides, engagement pieces 15 are provided, and release pieces 16 are provided near the engagement pieces 15, respectively.
The disadvantage is that the structure is complicated. In addition, the support part 12
Since the cut slits 13 are formed on the left and right sides, cracks are likely to occur from there, and the strength is also weak.

In order to solve this problem, a forehead frame connector as shown in FIG. 6 has been proposed (Japanese Utility Model Publication No. 53-94291).

The frame connectors of the forehead are an upright piece 17a and a horizontal piece 1.
There is a frame connector base 1 consisting of 7b, and its upright piece 17a and horizontal piece 17b are inserted into the guide grooves 18 of the vertical frame A and horizontal frame B, respectively, to form the slit portions 19 of the vertical frame A and horizontal frame B. The vertical frame A and the horizontal frame B are connected by engaging an engaging piece 21 which also serves as a release piece in the locking groove 20. By removing the joining piece 21, the connected vertical frame A and horizontal frame B can be disassembled.

However, the engagement piece 21 that also serves as the removal piece is an engagement piece that is removed from the locking groove 20 by moving toward the cylinder interior of the vertical frame A and the horizontal frame B. When removing the piece 21, there is a risk that the fingers may come into contact with the sharp edges of the locking grooves 20 formed in the vertical frame A and the horizontal frame B, causing injury.

In addition, since engaging pieces 21 are provided on the upright piece 17a and the horizontal piece 17b of the frame connector base 1, when disassembling the vertical frame A and the horizontal frame B, both engaging pieces 21 are engaged. The removal operation is troublesome because it has to be removed from the stop groove 20 respectively. In addition, the engagement piece 21
Since the frame itself is hard, there is a drawback that the vertical frame A and the horizontal frame B cannot be easily disassembled.

The present invention has been made in view of the above, and its purpose is to provide a frame connecting device for a frame, which allows the frame, that is, the connected vertical frame and horizontal frame, to be safely and easily disassembled.

[Means to solve the problem]

The forehead frame connector of the present invention is constructed by inserting one side and the other side of the frame connecting base into the guide grooves of the vertical frame and the horizontal frame of the forehead, respectively, and inserting the frame into the locking grooves formed in the vertical frame and the horizontal frame. In a frame connecting tool for assembling a frame by connecting the vertical frame and the horizontal frame by engaging the engaging pieces provided at both ends of the connecting base, each engaging piece is provided on the back side of the frame connecting base. , between both engaging pieces,
It is characterized by the provision of a reinforcing plate that also serves as a detachable piece that connects the two together.

[Effect]

If a reinforcing plate is provided between both engaging pieces provided at both ends of the back side of the frame connection base, which also serves as a removal piece to connect both together, the engaging pieces can be far away from the locking groove in which they are engaged. The engagement piece can be removed from the locking groove by operating a reinforcing plate that also serves as a separated removal piece. Therefore, the fingers can be removed without coming into contact with the edges of the locking groove, and injuries caused by contact with the edges of the locking groove are eliminated.

In addition, by removing the engaging piece from the locking groove by operating the reinforcing plate that also serves as a removal piece that connects both engaging pieces together, both engaging pieces provided at both ends of the frame connection base can be simultaneously removed. It comes off, and it also comes off with a small force due to the principle of leverage. Therefore, the vertical frame and horizontal frame can be easily removed.
