Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame material fixing device, and particularly to a fixing device that can fix another frame material in the middle of a long frame material in a right angle direction.

Generally, for furniture such as two shelves, a long frame material 1 is
Assemble and manufacture as shown in the figure.

In this case, if the frame material 1 is a hollow metal material, the frame material 1,
Although they can be integrated, in order to fix the frame material 12 in the right angle direction, a hole 3 is formed in the frame material 1 and the frame material 1 □, and the other flat plate 4 of this hole 3 is We must stop them and integrate the two.

However, this method requires a great deal of effort to form the holes 3, delays assembly work, causes dimensional errors, and weakens the connection strength.

An object of the present invention is to provide a frame material fixing device that allows one-touch identification of frame materials in the right angle direction, and will be described in detail below using examples.

FIG. 2 is a perspective view showing an embodiment of the frame material fixing device according to the present invention, and FIG. 3 is a sectional view taken along the line A-A in FIG. Both frame members 5 and 6 are made of square vibrators, and grooves 8 are formed in the squares of the frame members 5 and 6, and from the bottom of each groove 8 there are 2 The ribs 9 of the book protrude inward.

The fixing device 7 includes a core portion 10 and a cover portion 11 having a substantially right triangular shape.
The thickness of the core portion 10 is set to be approximately equal to the width of the groove 8, and a screw hole 12 is provided at the corner of the core portion 10.
A pin 13 is implanted near 2.

The cover part 11 has a holding part 18 on the orthogonal side 14 side, which is composed of a curved piece 16 that covers the corner part 15 of the frame members 5 and 6, and a blocking piece 17 that comes into contact with the side wall 8 □ of the groove 8.
A hole 19 is provided at a location where the screw hole 12 and pin 13 correspond.

That is, the first groove 8 having a plurality of grooves 8 extending in the longitudinal direction
．． In the fixing device for fixing the second pipe-shaped frame members in a direction perpendicular to each other, the plate members having orthogonal sides are used, and the plate members having the orthogonal sides are fixed to each other in a direction perpendicular to each other. A core part 10 that fits into each groove 8 of the second pipe-shaped frame material, and a core part 10 that is attached to the above-mentioned core part 10 and is connected to the first part. and a cover part 11 that holds the second pipe-shaped frame member, and the corresponding first part is located on the orthogonal side of the centering part 10. Curved pieces 16□, 16□ that cover the convex corner portions 15□, 15□ of the second pipe-shaped frame material, and the above-mentioned curved pieces 16□, 16□
A blocking piece 17□ bent from the end toward the bottom of the groove 8,
172 is provided on the cover part 11, and the cover part 11
Curved piece 16. ．． 16□, the blocking pieces 17□, 172, and the orthogonal sides of the core portion 10.
A part of the corner of the second pipe-shaped frame material is sandwiched between the 15□ and 152 sides.

In such a configuration, in order to fix the frame member 5 to the frame member 6, first, the screw 20 is screwed into the screw hole 12 through the hole 19, somewhat loosely.

Next, the insertion portion of one orthogonal side end frame member 6 of the core portion 10 into the groove 8 and the corresponding curved piece 16 and blocking piece 17 will be explained.
, the convex corner portion 15□ of the frame member 6 is inserted into the recess formed between .

Next, the convex corner portion 15□ of the frame member 5 is inserted into the recess formed between the other orthogonal side end of the core portion 7 and the curved piece 162 and the blocking piece 172.

Next, after positioning the frame material 5 and the frame material 6 in their proper positions, the screws 20 are firmly tightened.

As a result, a portion 15 of the convex corner of each frame member 5, 6 is in a state where it is engaged with the end of the orthogonal side of the core portion 10 and the holding portion 18, and both frame members 5, 6 are held together via the fixture 7. Fixed.

According to this embodiment, the holes 3 are connected to the frame members 5 and 6 as in the conventional
There is no need to provide a frame material 5, 6, and individualization can be done simply by tightening the screws 20, making the work extremely easy.
are determined with the bottom surfaces of the grooves 8 in contact with the orthogonal sides of the core 10, so that they are exactly orthogonal to each other, and no error occurs.

Further, since the load applied to the frame member 5 is transmitted to the frame member 6 mainly through the core portion 10, the connection strength between the two frames can be increased.

Further, since the pin 13 is provided, it penetrates into the hole 19 and serves as a guide, thereby preventing misalignment between the cover portion 11 and the core portion 10.

In addition, in the present invention, the end opening side 3 of the frame material 5 and the frame material 6
0 to each other, a connector 33 consisting of a main body 31 and a protrusion 32 projecting from the main body 31 in a perpendicular direction may be used, as shown in FIG.

That is, one of the protrusions 32 is connected to the frame members 5 and 6, respectively.
It may be press-fitted from the end opening side 30 against the rib 9.

Therefore, by using the fixture 7 according to the present invention and the connector 33 shown in FIG. 4, the assembly member having the structure shown in FIG. 1 can be easily manufactured.
