Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a cabinet used in television receivers and the like.

(B) Prior Art In general, television receivers have a cabinet of the type in which a synthetic resin rear cover is joined to a wooden front cabinet frame. In such a cabinet, conventionally, as shown in FIG. 1 or 2, when screwing the edge 3 of the rear cover to the reinforcing crosspiece 2 on the opening side of the front cabinet frame 1, A stopper 4 made of a plate spring (metal) is fitted into the reinforcing bar 2, or a stopper 5 made of synthetic resin is fitted.
are fixed with screws, and rear cover mounting screws 6 are tightened to these fasteners 4 and 5. The reason why such fasteners 4 and 5 are used is that when the rear cover 3 is directly screwed to the auxiliary crosspiece 2 with wood screws, the rear cover may be installed or removed many times for repair or inspection. This is to prevent the screw holes of the auxiliary crosspiece 2 from becoming so-called screw holes as the screws are being used.

By the way, the plate spring stopper 4 in the case of Fig. 1
Since it requires bending and drilling, the cost is high, and the screw 6 needs to be long enough to penetrate the reinforcing beam 2. Furthermore, the fastener 5 shown in FIG. 2 has to be screwed onto the reinforcing beam 2 from the lateral direction of the front cabinet frame 1, which has the disadvantage of extremely poor workability.

(c) Purpose of the invention This invention was created in view of the above points,
To provide a cabinet in which a front cabinet frame and a rear cover can be joined with very good workability by using an inexpensive joint made of synthetic resin.

(d) Structure of the invention In the cabinet of the invention, a through hole is provided in the wooden reinforcing frame attached to the opening edge of the front cabinet frame, and the first boss provided in the synthetic resin connector is connected to the through hole. The coupling tool is attached to the reinforcing bar by inserting it into the hole and engaging the reinforcing bar with an engaging piece that is provided on the coupling tool and prevents it from coming off in a direction opposite to the insertion direction, and attaching the coupling tool to the reinforcing bar; The rear cover is characterized by a structure in which the opening edge of the rear cover is screwed into an axial through hole of the second boss that protrudes in a direction parallel to the second boss.

(e) Embodiment FIG. 3 shows an embodiment of the cabinet of the present invention. In FIG. 3A, 11 is a wooden front cabinet frame, and 13 is a synthetic resin rear cover. Three wooden reinforcing bars 12 are adhesively fixed to the rear edges of the top plate 11a and side plates 11b, 11c of the cabinet frame 11, as in the case of the conventional example described above. Through holes 14 are formed in the reinforcing bar at four locations as shown in the figure, passing through the reinforcing bar in the front-rear direction. Reference numeral 15 denotes a synthetic resin coupling tool, which, as shown in FIG.
A second boss 17 for screw fixing having a diameter 7a is integrally molded. Then, the first
By press-fitting the bosses 16 into the through holes 14 of the reinforcing bar 2 from the inside of the bar, the four connectors 15 are attached to the front cabinet frame 11 as shown in FIG. 3a. At that time, as shown in Figure 3c, the second boss 17
The back side of the reinforcing bar 12 is in contact with the inner end surface of the reinforcing bar 12 to prevent the coupling tool 15 from rotating.

On the other hand, in the opening edge of the rear cover 13, there are through holes 18 for screw insertion at respective positions facing the second bosses 17 of the respective couplings 15 attached to the reinforcing beam 12.
is provided. Therefore, this rear cover 13
against the front cabinet frame 11, as shown in Fig. 3c.
When the tapping screw 19 passed through the through hole 18 of the rear cover 13 is tightened into the small hole 17a of the second boss 17 of the connector 15 as shown in FIG. In this state, the rear cover 13 is fixed to the front cabinet frame 11.

Next, FIG. 4 shows another embodiment of the cabinet of the present invention, and parts corresponding to the embodiment of FIG. 3 are given the same figure numbers. As shown in FIG. 4b, the coupling tool 15 of this embodiment includes a first boss 16 for positioning and a second boss 17 having a small hole 17a.
, a third boss 20 having a small hole 20a, and a locking pawl 21 are integrally molded and are made of synthetic resin.

In addition, each reinforcing bar 12 of the front cabinet frame 11
The first to third bosses 16, 1 of the coupling tool 15
Three through holes into which holes 7 and 20 are inserted are provided at four locations. Then, the first to third bosses 16, 1 of the coupling tool 15 are inserted into each of the four through holes.
7 and 20, the locking pawl 21 of this coupling tool 15 engages with the reinforcing bar 12 as shown in FIG. Installed. Here, the third boss 20 of the connector 15 is made slightly shorter than the second boss 17, and the tip of the third boss 20 is attached to the reinforcing bar 12 as shown in FIG. 4b. It becomes flush with the front surface of the crosspiece 12.

Then, in such a state, the first one of the coupling tool 15 is inserted into one 23a of the through holes 23a and 23b provided in the mounting pieces 22a and 22b of the printed board holding frame 22 made of synthetic resin.
The holding frame 22 is attached to the front cabinet frame 11 by screwing the tapping screw 24 passed through the boss 16 and through the other through hole 23b into the small hole 20a of the third boss 20. Although only one holding frame 22 on the left side is shown in FIG. 4a, one holding frame 22 can be similarly attached to the right side.

Next, with the printed board holding frame 22 attached as described above, the rear cover 13 is butted against the front cabinet frame 11, and the first boss 1 of the connector 15 is attached.
6 is inserted into one of the through holes 18a and 18b of the rear cover 13. Then, insert the tapping screw 19 into the other through hole 18b of the rear cover 13,
Insert this screw into the small hole 17 of the second boss 17 of the coupling tool 15.
By screwing the rear cover 13 into the front cabinet frame 11, the attachment of the rear cover 13 to the front cabinet frame 11 is completed. At that time, tighten the screws 19 on the rear cover 1.
3 is connected to the front cabinet frame 1 by the first boss 16.
Since the work can be carried out while it is temporarily fixed to 1, the workability is extremely good. In addition, coupling tool 1
Since the second and third bosses 17 and 18 of 5 are provided with a step, the screws 2 for attaching the printed board holding frame 22
4 does not get in the way in any way when attaching the rear cover 13.

(f) Effects of the invention According to the cabinet of the invention, an inexpensive connector made of synthetic resin can be used to connect the front cabinet frame and the rear cover, and this connector can be attached to the front cabinet frame. Since the screws can be easily tightened to this coupling tool, workability during assembly is good, and since a retaining piece is provided, the state of attachment of the coupling tool to the reinforcing frame is stable. Another advantage is that the coupling tool does not move back when tightening the screws, further improving workability.
