[Structure of the idea]

Γ Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a cabinet that connects a front cabinet and a back cover, by connecting a small number of connecting pipes to the rear inward surface of the front cabinet. Insertion groove, insertion hole,
an engaging stepped portion is provided, and an insertion hole for a screw connected to the connecting pipe is provided at the front edge of the back cover;
Fitting pieces for insertion into the front cabinet are provided protruding from the top, bottom, left and right of the front lip, respectively, and a protrusion that fits into the fitting groove from the front lip, and a protrusion that fits into the insertion slot from the front lip to the insertion opening. Means is taken to form an insertion piece to be inserted and an engagement/disengagement portion that engages with the engagement step.

Γ Structure of the Embodiment The present embodiment is for a television receiver, and the front cabinet 1 and back cover 2, which have various means described below, are each integrally formed of plastic. The front cabinet 1 includes a top plate 1a, a bottom plate 1b, and side plates 1c, 1c.
and a front frame 1d, a pair of connecting pipes 3, 3 are integrally formed on the rear inward surface of the upper surface plate 1a at a predetermined interval, and on the rear inward surface of the lower surface plate 1b, they are inserted into the center. A left and right backlash prevention means A having grooves 4, 4 is provided with an insertion port 5 and an engagement step 6 on the left and right sides, respectively.
Vertical rattling prevention and rear slippage prevention means B, B having
are integrally formed. As shown in the second figure, the left-right backlash prevention means A has a stepped portion 4a that is lower than the lower surface plate 1b, and both side edges are formed into a tapered shape, and a pair of fitting grooves 4 are formed at a predetermined interval on the lower surface 4b. , 4 are formed in parallel, and the entrance 4 of each fitting groove 4
c is widened, and there is an elongated opening 4d in front of the lower surface 4b.
As shown in the third figure, a portion 1b' of the lower surface plate 1b extends in the form of a thin plate above the elongated opening 4d. As shown in FIGS. 5 and 6, the vertical backlash prevention and backward slippage prevention means B has a step 6a lower than the bottom plate 1b, and a pair of front and rear engagement steps 6 and an elongated plate 5a are connected to the bottom opening 6b of the step 6a. It is integrally spanned between the engagement step portion 6 and the elongated plate 5a,
Furthermore, an elongated plate 5b is integrally extended upward, and an insertion port 5 is formed by the elongated plates 5a and 5b.

The back cover 2 is a plastic housing as shown in the first figure, and the front upper edge 2a of the back cover 2 is connected to the connecting pipes 3 and 3 as shown in the first and third figures.
Insertion holes 8, 8 are provided at opposing positions, a fitting piece 10 is provided from the front upper edge 2a, a fitting piece 9 is placed from the center of the front lower edge 2b, and fitting pieces 11, 11 are provided from the front left and right edges 2c.
11 is projected, and each fitting piece 9, 10, 11
The width diameters a, b, and c of the fitting pieces 9, 10, 11, and 11 are set in the relationship a>b>c, respectively, and both side edges of each of the fitting pieces 9, 10, 11, and 11 are cut into a widening shape. Fitting piece 10
A gap 15 is provided between the connecting pipe 3 and the bottom surface of the fitting piece 9 to match the fitting grooves 4, as shown in the second and fourth figures. It is integrally formed, and the tip of the protrusion 12 is tapered. Furthermore, as shown in the first diagram, a pair of insertion pieces 13, 13 are provided from the left and right sides of the front lower edge 2b.
is provided protrudingly, and a detachable portion 14 is provided at the tip of each insertion piece 13.
is formed into a hook shape.

Γ Example connection method From the rear of the front cabinet 1, first insert the fitting piece 9 and the insertion pieces 13, 13, then insert the fitting piece 10.
Finally, insert the fitting pieces 11, 11. The width diameters of the fitting pieces 9, 10, and 11 are a>b>c, and both side edges are cut in a widening shape, so that they can be easily fitted. By the above-mentioned fitting operation, each protrusion 12 is fitted into the fitting groove 4, and the lower surface of the fitting piece 9 is placed on the lower step surface 4b. Note that the step portion 4a and the fitting piece 9 are formed in a widening shape, and the entrance 4c of the fitting groove 4 is widened, and the tip of the protrusion 12 is tapered.
Easy to insert. Further, as shown in the fifth and sixth figures, each insertion piece 13 is inserted from each insertion opening 5. At this time, the engaging/disengaging portion 14 is slightly compressed, but since it is made of plastic, it returns to its original state after passing through the insertion port 5, moves forward further, and engages with the engaging stepped portion 6. Also, the fitting piece 10,1
The outward facing surfaces of 1 and 11 are the top plate 1a and the side plates 1c and 1.
c, and the connecting pipes 3, 3 are attached to the inward surface of
Located within 5.15. Thereafter, as shown in the third figure, each screw 7 is inserted through the insertion hole 8 and screwed into the hole 3a of each connecting pipe 3. Note that the hole 3a may be a screw hole, but in the case of this embodiment, it is a hole with a diameter slightly smaller than the shaft diameter of the screw 7, and is screwed in by the screw 7 in a tapping manner. This work is done on connecting pipe 3.
Since it is made of plastic, it can be made easily. Note that in order to disassemble the assembled cabinet, the steps described above can be reversed.

[Effect of idea]

In this way, this invention allows the cabinet to be assembled extremely quickly and easily by simply fitting the back cover into the front cabinet and fixing it with a few screws.Moreover, it is possible to assemble the back cover into the front cabinet by simply inserting the protrusion into the insertion groove. By inserting the insertion piece into the insertion port, vertical play can be prevented, and by engaging the disengagement part with the engagement stepped part, there is no risk of it coming off backwards, and at the same time Each fitting piece comes into contact with the inward surface of the front cabinet, and together with the screw fixing, a secure connection can be achieved, and only a small number of screws are required.
