Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame fixture, and more particularly to a frame fixture for attaching and holding a second frame member midway through a first frame member.

As shown in FIG. 1, the conventional fixture is a rectangular tube-shaped first frame member 1 disposed almost vertically.
Similarly, in the middle of the rectangular cylindrical second
When installing the frame material 2, first, the through hole 3 is bored in a direction substantially perpendicular to the side of the first frame material 1, and the second
A space member 4 is inserted into the end cylinder of the frame member 2,
A screw hole 5 is formed approximately in the center of this space member 4, and a screw 6 is used to connect the first frame member 1 and the second frame member.
This is a configuration in which the frame material 2 is fixed. However, in the case of a fixture that screws the second frame material 2 in the middle of the first frame material 1, it is necessary to provide a through hole 3, a space member 4, a screw hole 5, etc., which makes the molding work complicated, and The assembly work is also troublesome, and there are problems such as not being able to assemble it in a short time.

The present invention eliminates these drawbacks,
The present invention will be described in detail below based on the accompanying drawings.

2 and 3 are a perspective view and a plan view showing a state in which the second frame member is fixed in the middle of the first frame member using the fixture according to the present invention, and in the drawings, 10 is arranged almost vertically. The first frame material 1 shown in FIG.
0 has a pipe shape with a rectangular cross section, and rectangular concave grooves 11 are formed along the longitudinal direction on the four corners of the rectangular cross section. Furthermore, two long ribs 12 are formed along the longitudinal direction on the inside of the cylinder at the bottom of each groove 11 of the first frame member 10 . On the other hand, the first
The second frame member 14 attached to the frame member 10 by the fixture 13 according to the present invention is also formed in substantially the same manner as the first frame member 10. To explain the fixture 13 according to the present invention, a substantially rectangular main body 16 (shown in FIG. 4) is formed with a protrusion 15 that is a first protrusion that fits into the groove 11 of the first frame member 10. is fitted into the groove 11, and a V groove 17 having a V-shaped cross section along the groove 11 is formed in the center of the convex portion 15 of the main body 16.
A boss portion 17', which is a second convex portion having a rectangular cross section, is formed on the surface opposite to the surface on which the convex portion 15 is formed, and both side surfaces of the main body 16 adjacent to the surface on which the convex portion 15 is formed. A groove 18 substantially parallel to the longitudinal direction of the first frame member 10 is formed in each of the grooves 18 . Further, a fixing piece 23 having bent portions 21 and 22 formed at both ends of a plate-shaped base portion 20 that is screwed to the main body 16 with a screw 19 is attached to the first frame member 1
The bent portion 22 is inserted into and engaged with the groove 18 of the main body 16 and screwed to the main body 16 by the screw 19. Although the fixing pieces 23 are attached to both opposing sides of the main body 16, it is also possible to attach them to only one of the sides.

As described above, in order to attach the second frame member 14 to the middle of the first frame member 10 using the fixture 13 according to the present invention, first the boss portion of the main body 16 is
7' into the cylinder at one end of the second frame member 14,
stick. At this time, the rib 12 formed in the cylinder of the second frame member 14 is pressed and deformed by the boss portion 17', and the main body 16 is more firmly fitted and fixed to the end of the second frame member 14. . The convex portion 15 is the first frame member 1.
The main body 16 and the second
A frame material 14 is arranged. Furthermore, a fixing piece 23 is arranged on both opposing sides or one side of the main body 16,
At this time, one bent portion 21 of the fixed piece 23 is brought into contact with the side wall 11a of the groove 11 of the first frame member 10, and the other bent portion 22 is inserted into and engaged with the groove 18 of the main body 16. . Then, the fixing piece 23 is screwed to the main body 16 by the screw 19, and at the same time, the bent part 21 presses the groove 11 and the corner part of the first frame member 10 is pressed together with the convex part 15 of the main body 16. 1
0a, and the second frame member 14 can be attached to the middle of the first frame member 10 in a substantially orthogonal direction.

As described above, the mounting device according to the present invention is different from those that are mounted by forming through holes, screw holes, etc. in the frame material, and can be installed by forming the frame material in a certain shape by extrusion molding or the like. During assembly, there is no need to provide holes etc. in the frame material itself, and the first frame material 10
The second frame member 14 can be attached easily and in a short time at any location. At this time, when the corner portion 10a of the first frame member 10 is held between the bent portion 21 of the fixed piece 23 and the convex portion 15 of the main body 16, the bent portion 21 of the fixed piece 23 can be held by simply loosening the screw 19. can be inserted into the groove 11 of the first frame member 10, so there is no need to slide it from the end of the first frame member 10 and insert it into the groove 11, and the insertion is easy. Further, in this case, since the V-groove 17 is formed in the convex portion 15, a spring effect is generated in the convex portion 15, and the sandwiched state between the bent portion 21 and the convex portion 15 is prevented from loosening due to vibration or the like. Its utility value is remarkable.
