Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame that can be assembled by simple operations.

Generally, when configuring an audio rack etc.
As shown in FIG. 1, a cabinet 4 is composed of a top plate 1, a bottom plate 2, and a back plate 3. A frame-shaped support 5 is attached between the top plate 1 and the bottom plate 2, and a shelf board, etc. You may want to install it.

Conventionally, when constructing such a support, as shown in FIG. 2, both ends of square metal pipes 6 to 9 were each cut at 45 degrees and then welded together. Note that 10 and 10 are arranged between the upper and lower ends of the support 5 and the top plate 1 and the bottom plate 2, and
It is a mounting part for attaching to these top plate 1 and bottom plate 2, and a hole 10a for screw insertion is provided in the center, and through-holes 9a of square pipes 8 and 9 (through-holes of square pipe 8) are provided at both ends. The pins 10b and 10b are inserted into holes (not shown), and the pins 10c are inserted into through holes (not shown) in the top plate 1 and the bottom plate 2.
is provided.

However, if you do this, square pipes 6 to 9
The cutting process itself of cutting the flow end at 45 degrees is extremely difficult, and there is a problem in that it is difficult to achieve dimensional accuracy. Welding also takes time, and
There is also a problem in that it is extremely time consuming because surface treatment must be performed after polishing the weld marks during welding. Moreover, since the surface had to be treated after being assembled into a frame, there were problems such as the inner surface not being plated or paint not adhering to it, and the overall cost being extremely high. .

The present invention constitutes a frame that solves these conventional problems.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In FIGS. 3 and 4, 11 and 11 are metal square pipes, and the respective square pipes 11 and 11 are square pipes made of metal.
As shown in FIG. 4, through holes 11a (other through holes are not shown) are provided at both ends of the surfaces facing each other. 12, 12 are two square pipes 1
It is a decorative part arranged between 1 and 11, and is formed into a U-shaped cross section by an upper surface 12a and left and right side surfaces 12b, 12b.
A locking pawl 12c (the other one is not shown) is formed to be locked in one of the through holes 11a. Grooves 12d, 12d are formed between the side surfaces 12b, 12b and the locking claw 12c, into which ribs 13b of a joining component 13, which will be described later, are inserted. Note that this decorative component 12 is ultimately given the same surface finish as the square pipe 11. Reference numerals 13, 13 are joint parts integrally formed of resin, and have protrusions 13a, 13a on both sides of one side, which are press-fitted into the center holes 11b, 11b of the square pipes 11, 11, and the above decoration in the center. It has two ribs 13b, 13b that are inserted into the inner grooves 12d, 12d of the side surfaces 12b, 12b of the parts 12, 12, and there are through holes in the top plate 1 and the bottom plate 2 shown in FIG. 1 on both sides of the other side surfaces. Pin 1 inserted into
3c and 13c, and has a screw hole 13d in the center thereof. Note that the protrusion 13a is composed of four ribs joined together radially, and the ribs 13b are slightly inclined so that their tips are separated from each other.

In the above configuration, the locking claw 12 of the decorative component 12
c, 12c are the through holes 11a of the square pipes 11, 11,
11a, and in this state, square pipe 1
1 and 11 and the decorative part 12 as shown by the arrows in FIG. The tips of the decorative parts 12 are press-fitted into the grooves 12d, 12d, and a frame-shaped support as shown in FIG. 3 is finally constructed. At this time, the protrusions 13a, 13a are composed of four ribs joined radially, and if the tips of each rib are brought into contact with the four corners of the center hole of the square pipes 11, 11, the joint parts 13 There is no risk that the square pipes 11, 11 will be deformed due to the press-fitting.
The square pipe 11 and the connecting part 13 can be beautifully and firmly connected. Further, since the ribs 13b, 13b of the joint part 13 are inclined so as to separate from each other, the ribs 13b, 13b are strongly pressed against the inner surfaces of the side surfaces 12b, 12b of the decorative part 12 when press-fitting. Therefore, the bonding strength between the decorative component 12 and the connecting component 13 becomes extremely stable.

In this way, according to the above embodiment, the square pipe 11
Since there is no need to cut both ends at 45 degrees, the processing becomes extremely easy, and there is no need for welding, buffing, etc., so the work can be significantly simplified compared to conventional ones. Moreover, since the square pipe 11 and the decorative parts 12 can be surface-treated separately before being assembled into a frame shape, there is no problem that plating is difficult to adhere to the inside or uneven coating occurs, and the entire surface can be beautifully finished. Also, since surface treatment can be applied to the square pipe, even if one of the square pipes is damaged,
If you use this as a rectangular pipe in the back that you can't see, you can lower the overall defect rate.
In this respect as well, cost reduction can be achieved.

In the above embodiment, the case where the frame body is used as a support has been described, but it goes without saying that the present invention can also be applied to other decorative beams.

As described above, in the present invention, a frame is constructed from a square pipe and a decorative part by press-fitting a connecting part into the square pipe and a decorative part, so there is no need for welding, polishing, etc. This can significantly improve work efficiency. Furthermore, since surface treatment can be applied to the square pipes and decorative frames before assembly, uneven plating and uneven coating can be reduced, and an extremely beautiful frame can be constructed as a whole.
