Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a new cabinet for a television receiver or the like. Specifically, by improving the structure of the cabinet, the space inside the cabinet can be used effectively without unnecessary parts protruding into the cabinet, and the number of parts can be reduced. New television receivers, etc., which can reduce weight, significantly reduce the size, and significantly improve workability during manufacturing processes and maintenance work. It is intended to provide a cabinet.

BACKGROUND TECHNOLOGY AND PROBLEMS In recent years, television receivers and monitors have been required to be as compact as possible and to have multiple functions. In order to meet these demands, it is necessary to downsize various parts, to design the internal structure compactly, and to downsize the shape of the cabinet. In particular, in order to meet the above requirements, it is extremely important to be able to effectively utilize the space inside the cabinet without protruding any parts that are unnecessary for the internal structure as much as possible. be. This is because even if the internal devices housed in the cabinet are made as small as possible, it is difficult to connect or fix each part of the cabinet to the cabinet in which the internal devices are housed, or to support the internal devices. If the members for this purpose protrude, the shape of the cabinet cannot be made much smaller, and as a result, the overall size of the device cannot be made smaller.

FIG. 1 shows an example of a conventional cabinet such as a television receiver. In the figure, a
indicates the front panel. The front panel a has a frame c to which a cathode ray tube b is attached, and a frame c below this.
and a control panel part d integrally formed. Denoted at e is a control section mounted on the control panel section d, and is provided with various operation switches and display members. f is a back cover that is open at the front and has a substantially housing shape, and although not shown in the figure, mounting stays are protruded at several places around the front opening, and the mounting stays are attached to the front panel a with screws. etc., so that the front panel a and the back cover f are integrated. g and g are legs attached to both sides of the lower back of the front panel a, and the legs g and g are arranged so that their front end surfaces h and h are butted against the lower back of the front panel a. Then, the mounting pieces i, i are fixed to the front panel a with screws or the like. Reference characters j and j are rail parts attached to the upper surfaces of the legs g and g by appropriate means, and grooves having, for example, an inverted T-shaped cross section are formed. k is a chassis, on the top surface of which a circuit board l is attached; on both sides of the lower part there are formed protrusions that engage with the grooves formed in the rails j, j; are slidably attached to the legs g, g via rails j, j. Denoted at m is a control board attached to the back surface of the control panel section d, on which various circuit components constituting the control circuit are provided.
Note that n indicates a side board, and various circuit components constituting a signal system circuit are provided on this side board. Further, the above-mentioned substrate 1 is provided with various circuit components constituting a deflection system circuit. The cathode ray tube b is attached to the front panel a by a holding member called a CRT shield (not shown). o
indicates the speaker section.

The conventional cabinet shown in FIG. 1 has the above-mentioned structure. This conventional cabinet configuration consumes space within the cabinet in a highly unreasonable manner. This is because the legs g, g and the rails j, j protrude into the inside of the cabinet. Legs g and g are members that support the weight of the cathode ray tube attached to front panel a and speaker a, so they need to be quite strong, and as shown in leg g and g shown in Fig. If it is formed separately from front panel a,
It needs to be particularly robust, and therefore the legs g are made of fairly thick members, and the means for connecting them to the front panel a is also made to have a fairly sturdy structure. Then, the legs g, g and the front panel a
The design will include the area for butting with the back. Therefore, for example, the speaker section o provided in the control panel section d is positioned considerably above the control panel section d.

Since the legs g, g are protruding from the lower part of the space inside the cabinet, and the rail parts j, j are attached, the lower part of the internal space becomes narrow, and even worse, the rail parts j, j are attached. Part j,
It is said that the space below the chassis k attached to the chassis k is not used at all and is extremely inefficient in space utilization.

Furthermore, when assembling the cabinet, a step is required to attach the legs g, g to the front panel a, and a step is also required to attach the rail sections j, j to the legs g, g, which reduces the number of man-hours in the assembly process. There are also problems when there are too many.

As mentioned above, the legs g and g are made of fairly thick members, and the rails j and j are also made of members with some degree of rigidity, so the weight of the cabinet becomes quite heavy. There is also.

Another problem is that maintenance work is difficult due to the structure of the cabinet shown in FIG. In particular, the work of inspecting, adjusting, or repairing the control board attached to the back of the front panel a is extremely troublesome. This is because the control board m is attached to the lower part of the back of the front panel a.
Chassis k with board l attached is placed behind control board m, so in order to modify control board m, it is first necessary to pull out chassis k backwards along rail parts j, j. This is because it is said that However, since television receivers and the like are usually placed against walls in rooms, there is often not enough space to pull out the chassis k sufficiently to the rear.
In order to extract this, it is necessary to change the arrangement of the television receiver. Even if the chassis k is pulled out in this way, since the cathode ray tube b is installed close to the top of the control board m, maintenance work may not be carried out as expected due to interference from the cathode ray tube b.
In such a case, the cathode ray tube b must be removed one by one.

As mentioned above, conventional cabinets suffer from a number of problems, including the inability to make effective use of the internal space and downsizing, the large number of parts and heavy weight, and the large number of man-hours required for assembly and maintenance. had.

Purpose of the invention The present invention has been devised in view of the above-mentioned problems. It is possible to effectively utilize the space inside the cabinet, reduce the number of parts, reduce weight, and significantly reduce the shape. The object of the present invention is to provide a new cabinet for a television receiver, etc., which can be downsized and can significantly improve workability during manufacturing processes and maintenance work.

Summary of the invention In order to achieve the above-mentioned object, the present invention divides the front panel into a frame body and a base, and the base has a front part whose upper part is connected to the lower part of the frame body, and a front panel whose upper part is connected to the lower part of the frame body. It consists of a bottom part protruding from the lower part of the frame toward a side corresponding to the side on which the cathode ray tube is attached to the frame body, and the bottom part has a rail part on which a chassis member is slidably attached. It is characterized by the fact that it has been formed.

It is designed to fit into a gap-like space (not shown) formed between the CRT shield 5 and the CRT shield 5. The bottom part 13 has reinforcing ridges 20, 20 connected to the front part 12 on both side edges, and the top surface of the bottom part 13 is a flat surface. And the bottom part 13
Rail portions 21, 21 extending along the protruding direction of the bottom surface portion 13 are formed in the central portion of the lower surface of the slider 1 so as to be parallel to each other. That is, in the central part of the bottom part 13, the bottom part 1 extends along the protruding direction of the bottom part 13.

Walls 75 and 76 are formed by providing reinforcing frames 73 and 74 on the sides opposite to the rear frame piece 65b above and below the reinforcing rib 69, respectively, and hinge members are attached to these walls 75 and 76, respectively. Mounting holes 77, 77' are formed. In addition, the holes for attaching each hinge member described above are as follows:
71 and 71', 72 and 72', and 77
and 77' are formed at vertically corresponding positions, respectively. 78, 78, 79, 79, and 80, 80 are presser claws, respectively.

d intersects toward the side frame piece 47c of the bottom chassis 46, and this receiver 82 and the side frame piece 47c of the bottom chassis 46
A locking mechanism for locking the rotation of the side chassis 64 is constituted by the protrusion 83 protruding from the side surface. That is, the protrusion 83 has a thickness such that the tip thereof is tightly fitted into the inner surface of the receiving tube 82, and the side chassis 64 is placed in parallel with the side frame piece 47c of the bottom chassis 46. At times, the tip of the protrusion 83 is fitted into the receiving tube 82, thereby locking the movement of the side chassis 64 so that it cannot easily rotate. Thus, the side chassis 64 has a lower front cylindrical portion 66.
A shaft 59 in front of the bottom chassis 46 is rotatably fitted to the bottom chassis 46, thereby being rotatably connected to the bottom chassis 46, and therefore can be rotated in the horizontal direction about the shaft 59 as a rotation center. At the same time, it is supported relative to the bottom chassis 46 so that its rotation is locked by lock mechanisms 82 and 83.

84, 85 and 86 are signal system circuit boards, respectively, and the signal system circuit is divided into these three boards, and each board 84, 85 and 86 is rotatably attached to the side chassis 64. It will be worn.

The first board 84 of the signal system is sized to cover substantially the entire area of the side surface of the outer frame 65 on the bottom chassis 64 side, and the front end of the board 84 is attached to the side surface of the side chassis 64.
It is rotatably attached to the body via a hinge member 87. Reference numerals 88 and 88' designate holes for attaching hinge members formed above and below the front end of the base plate 84, respectively, and the hole 88 is connected to the hole 72 formed in the side chassis 64, and the hole 88' is connected to the hole 72'. They correspond to each other in terms of location. Hinge members 87 and 87 are installed between holes 88 and 72 and between holes 87' and 72', respectively.

Here, the hinge member 87 will be explained (first
(see Figure and Figure 12). The hinge member 87 is made of a synthetic resin material having some degree of flexibility. Reference numeral 89 denotes a base having an L-shape in plan view;
A rib 90 formed in a cross shape is provided inside the rib 9 . Reference numeral 91 denotes a fixed-side engaging head projecting from the center of one wall 89a of the base 89, and the engaging head 91 has a planar shape and is formed approximately in the shape of an arrowhead. A rotating wall 92 extends from the tip of the other wall 89b of the base 89 via a thin hinge member 93, and extends outward from the center of the rotating wall 92 to the engaging head 91. A rotating side engaging head 94 formed in the same manner as above is provided in a protruding manner. Thus, if the fixed side engaging head 91 is inserted into the hole 72 or 72' formed in the wall 70 of the side chassis, the engaging head 91
passes through the hole 72 or 72' while the engaging pieces 91' and 91' on both sides are folded together,
After passing through the hole 72 or 72', the engaging pieces 91', 91' on both sides are restored to their original state and engaged with the wall surface of the wall 70, so that the hinge member 87
is attached to the chassis 64 so that a part of the wall 70 of the chassis 64 is sandwiched between the engaging head 91 and one wall 89a of the base 89. Similarly, the rotating side engaging head 94 is inserted into the hole 88 or 88' of the base plate 84, and both engaging pieces thereof are inserted into the hole 88 or 88'.
4' and 94' are engaged with the surface of the board 84, so the hinge part 87 is also attached to the board 84 with a part of the board 84 sandwiched between the engaging head 94 and the rotating wall 92 ( 12). Since the upper and lower front portions of the substrate 84 are supported by the chassis 64 via the hinge members 87, 87, the substrate 84 can be rotated horizontally with respect to the chassis 64. That is, when the substrate 84 is rotated in the direction indicated by the arrow in FIG. 12 from the state shown by the solid line in FIG. 12, the rotation wall 92 is rotated integrally with the substrate 84 via the thin hinge portion 93. ,
The base plate 84 is folded up until it becomes parallel to the chassis 64, and the base portion 89 and the rotating wall 92 form a U-shape (the state shown by the two-dot chain line in FIG. 12). Of course, by rotating the base plate 84 in the direction opposite to the arrow from the folded state, the base plate 84 can be opened to a state perpendicular to the chassis 64.

95 is a notch formed by cutting out the bottom rear corner of the base plate 84, and the receiving cylinder 82 of the lock mechanism provided on the side chassis 64 passes through this notch 95 to the bottom chassis 46 side. stand out. Note that when the substrate 84 is brought into a state parallel to the side surface of the chassis 64, a portion of the upper edge and lower edge of the substrate 84 are held by the presser claws 80, 80, so that the substrate 84 is It is locked so that it cannot be rotated. The operation when the upper and lower edges of the substrate 84 are partially held by the presser claws 80 is such that the peripheral edge of the deflection system substrate 61 is held by the presser claws 5 on the bottom chassis 46 described above.
3, 53, and 53, the explanation thereof will be omitted here.

The second board 85 of the signal system is the front part of the side surface opposite to the bottom chassis of the outer peripheral frame 65, that is, the front frame piece 65.
a, the rib 69, and the upper and lower frame pieces 65c, 65d, and the front end of the base plate 85 rotates with respect to the side chassis 64 via the hinge member 87 mentioned above. Can be attached freely. Reference numerals 96 and 96' are holes for attaching hinge members formed above and below the front end of the base plate 85, and the upper hole 96 is the hole 71 formed in the side chassis 64, and the lower hole 96' is the hole 71 formed in the side chassis 64. 71', respectively. A hinge member 87 is installed between the hole 96 and the hole 71 and between the hole 96' and the hole 71', respectively. The attachment state of the hinge member 87 installed between the holes 96, 96' of the base plate 85 and the holes 71, 71' of the chassis 64 and the rotational movement of the base plate 85 made possible by the hinge member 87 are determined by the aforementioned base plate. The manner of attachment and rotation between the hinge member 84 and the hinge member 87 are exactly the same.
Since the upper and lower front parts of the board 85 are supported by the chassis 64 via the hinge members 87, 87, the board 85 is supported by the chassis 64 in correspondence with the front part of the side surface of the chassis 64 opposite to the bottom chassis 46. It can be placed in a state parallel to the chassis 64, or it can be placed in an open state relative to the side surface of the chassis 64 by rotating horizontally via hinge members 87, 87, if necessary.
Note that when the board 85 is placed parallel to the side surface of the chassis 64, parts of the upper and lower edges of the board 85 are held by the presser claws 78, 78, so that the board 85 can be moved freely. It is locked so that it cannot be rotated.

The third board 86 of the signal system is the rear part of the side surface of the outer peripheral frame 65 opposite to the bottom chassis 46, that is, the rib 69, the rear frame piece 65b, and the upper and lower frame pieces 65c, 6.
The front end portion of the substrate 86 is rotatably attached to the side chassis 64 via the hinge member 87 described above. Reference numerals 97 and 97' are holes for attaching hinge members formed above and below the front part of the board 86, and the hole 97 is connected to the hole 77 formed in the side chassis 64, and the hole 97' is connected to the hole 77'. The hinge members 87 are attached between the holes 97 and 77 and between the holes 97' and 77', respectively. Holes 97, 97' in substrate 86
The manner in which the hinge member 87 is attached between the holes 77, 77' of the chassis 64 and the rotation of the base plate 86 made possible by the hinge member 87 are based on the base plate 84 and the hinge member 87, which are also described above. The manner of attachment and rotation between the chassis 64 and the chassis 64 are exactly the same. Since the upper and lower front ends of the board 86 are supported by the chassis 64 via the hinge members 87, 87, the board 86 is supported by the chassis 64 in correspondence with the rear portion of the side surface of the chassis 64 opposite to the bottom chassis 46. It can be placed in a parallel state, or if necessary, it can be turned in a horizontal direction via the hinge members 87, 87 to make it open to the side surface of the chassis 64. Note that the board 86 is the chassis 64.
When the substrate 86 is parallel to the side surface, a portion of the upper edge and lower edge of the substrate 86 are held by the presser claws 79, 79, thereby preventing the substrate 86 from being rotated without permission. It will be locked like this.

As described above, in the chassis block 45, the bottom chassis 46 and the side chassis 64 are connected to each other in such a manner that the side chassis 64 can rotate relative to the bottom chassis 46. Handling operations during adjustment and wiring of each attached circuit board and during service after being assembled into a set can be carried out extremely easily and rationally. That is, the bottom chassis 46 to which the deflection system board 61 is attached, and each signal system board 84, 85, 86.
The respective boards 61, 84, 85 and 86 are connected to the side chassis 64 to which the boards 61, 84, 85 and 86 are connected by rotatably fitting the connecting parts 59 and 66 to each other.
can all be combined into one board block. Therefore, the work of wiring the cord between the substrate 61 and the substrate 84 can be easily performed. Further, since it is often necessary to adjust the circuit parts of each circuit configured on all of the boards 61, 84, 85, and 86 while relating all the circuit parts to each other, each board is one block. It is very convenient for the adjustment work to be summarized in the following. Then, when performing maintenance or other services after the chassis block 45 and various boards 61, 84, 85, and 86 have been incorporated into the set, the necessary boards can be replaced without having to take out all the chassis blocks 45 from the set. You can only modify it. For example, when modifying only the deflection system board 61, pull the bottom chassis 46 backward from the base 11, and if necessary, rotate the side chassis 64 relative to the bottom chassis 46 to open it laterally. ,
The substrate 61 can be easily modified. Also, when modifying only the first board 84 of the signal system, by rotating the side chassis 64 and opening it to the side in the same way, the board 84 can be taken out to the outside of the set. This work is also easy because it can be put in a state like this. Furthermore, the chassis 64 of each of the signal system boards 84, 85 and 86 attached to the side chassis 64
When touching the back side of the board on the side opposite to the side surface, the respective boards 84, 85, and 86 are released from the holding pieces 78, 79, 80, and the side chassis 64 is moved through the hinge members 87, 87, . . . This operation is also easy because the back side of each board can be easily exposed by rotating it relative to the board.

Effects of the Invention As is clear from the above description, the cabinet of the television receiver of the present invention is formed by dividing the front panel into a frame and a base, and the base has an upper part connected to a lower part of the frame. and a bottom part that protrudes from the lower part of the front part toward a side corresponding to the side where the cathode ray tube is attached to the frame, and a chassis member is attached to the bottom part. A feature is that a rail portion is formed to be slidably attached.

Therefore, according to the present invention, since no unnecessary members for the internal structure are protruded into the inside of the cabinet, the space inside the cabinet can be effectively used only for accommodating the internal devices. . In addition, since the legs are formed integrally with the base, there is no need to prepare a butting area on the front panel for attaching the legs unlike in conventional cabinets, so the height of the cabinet can be reduced accordingly. It can be made smaller.

Since the cabinet part is formed integrally with the bottom part of the base, the number of parts can be reduced and the weight of the cabinet can be reduced.

Furthermore, since the front panel is divided into a frame body to which the CRT is attached and a base to which the control panel is attached, it is possible to remove the CRT together with the frame from the base. The cathode ray tube can be easily removed if necessary when modifying the board, making maintenance work on the control board extremely easy.
