Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel connecting structure for connecting adjacent portions of panels used for partitioning a room, for example.

[0002]

2. Description of the Related Art Conventionally, when connecting adjacent parts of panels used for partitioning or the like, the protruding parts provided at the end parts of the adjacent panels are overlapped and fastened with bolts and nuts.

[0003]

However, in the above-mentioned conventional panel connecting structure, the male screw portion of the bolt is screwed into the nut and the adjacent panels are connected by tightening the nut. There was a problem that the work efficiency was poor because it had to be turned many times.

The present invention solves such a problem, and an object of the present invention is to make it possible to connect adjacent panels to each other easily and efficiently.

[0005]

In order to solve this problem, the present invention provides a plurality of overhanging parts which are provided at the ends of adjacent panels over a substantially entire length thereof. Align the holes of the Daruma type with each other, and provide a head with a diameter smaller than the large diameter section of the Daruma type hole and larger than the small diameter section at the tip of the shaft, and at a suitable distance from the head. By inserting the head portion of the tightening fitting having the inclined flange portion on the upper side, after inserting the head portion into the large diameter portion of the daruma-shaped hole, and rotating the head portion in the state of being positioned on the small diameter portion side, the overlapped protruding portion is removed. It is configured to be sandwiched between the head portion and the inclined collar portion.

[0006]

With the above construction, when connecting the panels together, the tightening metal fittings are 90 degrees to 180 degrees as compared with the conventional case where the nut is turned many times with a spanner or the like.
It only needs to be turned a few times, and it is easy and efficient to connect adjacent panels.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIGS. 1 to 3 will be described. Reference numeral 1 is two panels connected so that their end faces are overlapped with each other. The projecting portions 2 and 2 are overlapped with each other, and in the overlapped state, the bulfer-shaped holes 3 and 3 provided at a plurality of positions on the projecting portions 2 and 2 are aligned with each other, and the tightening metal fitting 4 is fitted into the daruma-shaped holes 3 and 3. Is inserted to connect the two panels 1 and 1.

More specifically, the holes 3 of each daruma type are formed by connecting a small diameter portion 3a and a large diameter portion 3b. Further, the tightening fitting 4 is provided with a head 5 having a diameter smaller than the large diameter portion 3b of each of the daruma-shaped holes 3 and larger than the small diameter portion 3a at the tip of the shaft 6, and an appropriate distance from the head 5. An inclined collar portion 7 is provided on the shaft 6, and the overlapped projecting portions 2 and 2 are sandwiched between the head portion 5 and the inclined collar portion 7. It should be noted that an uneven portion 8 by knurling is formed on the inner surface portion of the inclined collar portion 7 that is closest to the head portion 5.
Is formed, and is configured so as to be pressed into one of the overhanging portions 2 and 2 while biting.
Reference numeral 9 is a handle portion formed by bending the other end of the shaft 6.

In the above structure, the two panels 1, 1
The case where the end faces are connected so that the end faces overlap each other will be described. With the protruding portions 2 and 2 of the panels 1 and 1 stacked, the head portion 5 of the tightening metal fitting 4 is inserted into the duller-shaped hole 3 and the large diameter portion 3b. Insert more. After that, the shaft 6 of the tightening fitting 4
Is moved to the small-diameter portion 3a side of the daruma-shaped hole 3, the handle portion 9 is gripped, and the fastening metal fitting 4 is rotated by about 90 to 180 degrees. As a result, the concave-convex portion 8 of the inclined flange portion 7 of the tightening fitting 4 is pressed against one of the overlapped protrusion portions 2 and 2, and the overlapped protrusion portions 2 and 2 are connected to the head portion 5 and the inclined collar portion 7. It is sandwiched between them. The head 5
And the sloped collar portion 7 are spaced apart from each other by the overlapping protruding portion 2,
It is appropriately determined according to the thickness of 2.

Next, in a second embodiment shown in FIG. 4, in order to adjust the distance between the head portion 5 and the inclined collar portion 7 in accordance with the thickness of the overhang portions 2 and 2, Head 5
The nut 10 provided with is screwed onto the male screw portion 11 at the tip of the shaft 6.

By the way, in the embodiment shown in the drawings, the case where the two panels 1 and 1 are connected so that the end faces thereof overlap each other is shown, but the case where the two panels 1 and 1 are connected at a right angle can also be carried out. Needless to say.

[0012]

As described above, according to the present invention, when connecting the panels together, compared with the conventional case where the nut is turned by a wrench many times and tightened, the tightening metal fitting is 90 degrees to 180 degrees. It only needs to be turned a little, and the adjacent panels can be connected easily and efficiently.

Claims (1)

[Claims] 1. The above-mentioned daruma-shaped holes are formed by aligning the bulge-shaped holes provided at a plurality of positions in the bulged portions with the bulged portions provided over the entire length of the adjacent panels being overlapped with each other. The head portion of the tightening fitting is provided with a head portion having a diameter smaller than that of the large diameter portion and larger than that of the small diameter portion at the tip of the shaft, and an inclined collar portion is provided on the shaft at an appropriate distance from the head portion. Is inserted into the large-diameter portion of the Daruma-shaped hole and then rotated while being positioned on the small-diameter portion side so that the overlapped protruding portion is sandwiched between the head portion and the inclined collar portion.
