Description

  The present invention relates to a front cabinet of a display housing which is a thinned display device such as an electronic device such as a liquid crystal TV or a plasma TV, and a part of a front frame made of a plastic material, for example, an upper frame portion or a left frame portion. By using a metal material such as an aluminum material, an object of the present invention is to improve the texture of the outer casing, to provide design features, and to obtain a display casing of a display device in consideration of recyclability.

For example, a liquid crystal TV (television) or a plasma TV (television) may be cited as an example of a thin display device as an electronic device. This type of thin display device includes a front cabinet that forms a front panel of the four circumferences of the display device, and a rear cabinet that protects the display device disposed on the back side of the front cabinet. For example, the front cabinet is often made of a plastic material, but a metal film sheet is attached to the surface of the plastic material in order to give a high-class feel to the front cabinet, and a CRT (cathode ray tube) type television is used. In some receivers, the front cabinet material itself uses a metal material such as aluminum.

    However, in the case of a front cabinet in which a metal film sheet is attached to the surface of a plastic material, there is a problem that the metal film sheet may be peeled off.

  Incidentally, in FIG. 2 of [Patent Document 1], the front cabinet of the CRT type television receiver is a metal material such as an aluminum extrusion material, a top frame 20, a right frame 22, a left frame 24, and the like. The bottom frame 26 is composed of four frames, and a corner bracket 30 made of a zinc die-cast material as a metal material is interposed at each corner portion of an adjacent frame, and is integrally connected in a rectangular shape using a tapping screw 40. What has been made to be disclosed is disclosed.

  However, the front cabinet as described above has a problem that since the entire front cabinet is made of an aluminum material, the front cabinet itself cannot make a design difference and the texture does not appear. Further, in the case of a CRT type television receiver, the depth of the receiver can be increased, so that the depth of the front cabinet itself can be increased, and the above-described frames can be connected by the corner bracket 30. Therefore, it is difficult to apply such a structure to the structure of the front cabinet of the display device that is thinned.

  [Patent Document 2] shows a structure of an example of a front panel of a plasma display device thinned as a display device. This front panel is a front panel in which an upper piece and left and right side pieces are integrated, and a structure in which a lower piece is stretched with a net for a speaker is disclosed.

  For example, the front panel constructed in this way is assumed to be integrally molded from plastic material, metal material, etc., but the front panel itself can not be designed differently and the texture does not appear There is.

  In order to solve the above problems and achieve the object of the present invention, the display housing of the electronic device according to claim 1 according to the present invention is such that the front cabinet of the display device, which is a display device, is substantially composed of two frame members. A display housing in which one of the two opposing frame members is molded from a plastic material and the other two opposing frame members are made of a metal material. The metal frame member is made to be held with the auxiliary bar suspended integrally between the opposing plastic frame members as the back, and the metal frame member made of a metal material has both ends at the plastic frame member. It is characterized by being fixed by a fixing means that can be disassembled.

  According to the display casing of the electronic device according to the first aspect of the present invention, it is possible to make a design difference in the front cabinet and to improve the appearance of the appearance. In addition, the thin display housing can be securely fixed in a small space without variation. By removing the fixing means, the metal frame member can be easily separated from the plastic frame member, and recycling can be easily realized.

  Hereinafter, the best mode of a display casing of an electronic device according to the present invention will be described with reference to the drawings, taking a display casing of a liquid crystal TV as an example.

  FIG. 1 is an external perspective view of a liquid crystal TV as viewed from the front cabinet side constituting the four-round frame of the liquid crystal screen, and FIG. 2 is a perspective view of only the front cabinet as viewed from the back side.

FIG. 3 is a perspective view showing a state in which the metal frame member of the upper panel is separated from the metal frame members in which the upper and lower panel portions of the front cabinet 1 are made of a metal material.

  The front cabinet 1 includes a quadrilateral frame-like plastic frame member made of a plastic material such as an ABS resin material and a metal frame member made of a metal material. The two opposite side frame members on the left and right sides are plastic side frame members 6 and 7 whose surfaces are decorated, and both side frame members 6 and 7 are thin reinforcing bars at their upper and lower end portions. 8 and 9 are integrally connected.

  The details of the reinforcing bars 8 and 9 and the plastic side frame members 6 and 7 will be described with respect to the upper reinforcing bar 8. The reinforcing bar 8 is connected so as to be passed to the back side of the plastic side frame members 6 and 7. Therefore, the ends 6a and 7a on the surface side of the plastic side frame members 6 and 7 are cut off. Slit grooves 10 and 11 are formed between the cut-off plastic side frame members 6 and 7 and the reinforcing bar 8. A concave surface 12 is formed over the entire upper surface of the reinforcing bar 8 so as to surround the slit grooves 10 and 11.

  Reference numerals 13 and 14 denote metal frame members made of a metal material constituting the upper and lower frames of the front cabinet 1. The metal frame members 13 and 14 are formed, for example, by extrusion molding of an aluminum material or an alumite material. The surfaces of the metal frame members 13 and 14 may be glossy or matte.

  Since the configuration of the metal frame members 13 and 14 is vertically symmetrical, the configuration of the upper metal frame member 13 will be described.

  On the upper side of the metal frame member 13, a bowl-shaped flange portion 15 is formed that is bent backward. The left and right end portions of the metal frame member 13 are formed with two grooves 16 and 17 having different lengths on the inner side and on the outer side in a stepped shape, and there are no grooves above the shorter groove hole 17. A hole 18 is opened in the hole.

  The metal frame member 13 described above is inserted from the slit grooves 10 and 11 of the plastic side frame members 6 and 7 and is fixed by fixing means described later, thereby constituting the upper frame of the front cabinet 1.

  4 is an enlarged perspective view of one end portion of the metal frame member 13 and the plastic side frame member 6 as viewed from the front side of the front cabinet 1, and FIG. 5 is also an end portion of the metal frame member 13, FIG. 6 is a perspective view of the plastic side frame member 6 from the back side of the front cabinet 1, and FIG. 5 shows the structure of the fixing means for the metal frame member 13.

  On the back surface of the plastic side frame member 6, two stepped bosses 19, 20 are projected at positions corresponding to the two slots 16, 17 of the metal frame member 13 described above, and at the center of both bosses 19, 20. Screw holes 19a and 20a are formed.

  Reference numeral 21 denotes, for example, an array-shaped holder made of a plastic material serving as a fixing means for the metal frame member 13. Through holes 22 and 23 are formed on both ends of the holder 21 so as to be engaged with the outer peripheral surfaces of the bosses 19 and 20 described above. Further, a rib 24 is provided on one side of the holder 21, and a pin 25 is provided on the back side of the rib 24 to be engaged with a hole 18 formed in the metal frame member 13.

  Next, how the metal frame member 13 is fixed to the plastic side frame member 6 will be described with reference to FIGS. 4 to 7 by taking one end of the metal frame member 13 as an example.

  First, as shown in FIGS. 4 and 5, the metal frame member 13 is inserted into the slit groove 10 from above the plastic side frame member 6. Here, the inserted metal frame member 13 is inserted such that the two slots 16 and 17 are respectively engaged and guided by the two bosses 19 and 20 on the plastic side frame member 6 side. When the insertion of the metal frame member 13 is completed, the flange portion 15 of the metal frame member 13 fits into the concave surface 12 on the upper surface of the plastic side frame member 6 and the holes 16 and 17 of the metal frame member 13 are inserted. The end portion comes into contact with the bosses 19 and 20 (see FIG. 6), and the metal frame member 13 is positioned relative to the plastic side frame member 6 without backlash.

  Thereafter, the holder 21 and the through holes 22 and 23 are inserted into the bosses 19 and 20 from the back side of the metal frame member 13. By inserting the holder 21, the pin 25 provided on the rib 24 is engaged with the hole 18 formed in the metal frame member 13. Finally, by screwing the screws 26 and 26 into the screw holes 19a and 20a of the bosses 19 and 20 through the through holes 22 and 23 of the holder 21, the metal frame member 13 is sandwiched between the plastic side frame member 6 and the holder 21. Fixing is complete.

  By fixing the metal frame member 13 as described above, the stepped bosses 19 and 20 are screwed by the holder 21 and the pins 25 of the holder 21 are engaged with the holes 18 formed in the metal frame member 13. As a result, the metal frame member 13 does not have a gap between the plastic side frame member 6 and has a firm structure without rattling, and the pin of the holder 21 can be fixed. By engaging 25 with the hole 18 formed in the metal frame member 13, the metal frame member 13 can be reliably prevented from coming out.

  In addition, since the metal frame member 13 is joined and supported by the reinforcing bar 8 suspended over the plastic side frame members 6 and 7, the metal frame member 13 is a case where a thin-walled aluminum material is used. Even so, the strength of the upper frame of the front cabinet can be maintained sufficiently.

However, the metal frame member 14 on the lower side of the front cabinet 1 has the same fixing structure. In this case, the metal frame member 14 is inserted from below the left and right plastic side frame members 6 and 7.

  FIG. 2 shows a state in which the upper and lower metal frame members 13 and 14 are fixed to the left and right plastic side frame members 6 and 7 by the holder 21 from the back side. The rear cabinet 2 in which liquid crystal display elements, circuit boards, and the like are accommodated with the front cabinet 1 thus configured is screwed to a plurality of retaining bosses 27 protruding from the back surfaces of the left and right plastic side frame members 6 and 7. As a result, the liquid crystal TV as shown in FIG. 1 is obtained.

  As described above, the display housing of the present invention has the upper and lower frames from the metal frame members 13 and 14 such as aluminum materials with respect to the side frame members 6 and 7 in which the left and right frames of the front cabinet 1 are made of plastic material. By being configured, it is possible to make a design difference in the front cabinet 1, improve the appearance of the front cabinet 1, and provide a high-class feeling such as a liquid crystal TV.

  Further, as a fixing means for the metal frame members 13 and 14, a pair of holes of the holder 21 are inserted into the bosses 19 and 20 of the plastic side frame members 6 and 7, and the holder 21 is screwed to the bosses 19 and 20 with screws. Then, the metal frame members 13 and 14 are sandwiched and fixed, and the pin 25 provided on the holder 21 is engaged with the hole 18 formed in the metal frame members 13 and 14, thereby reducing the thickness. The display housing can be securely fixed in a small space without variation. Further, the metal frame members 13 and 14 can be prevented from coming off.

  Moreover, by removing the screws of the holder 21, the metal frame members 13, 14 can be easily separated from the side frame members made of a plastic material, and recycling can be easily realized.

  The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

  In the display housing according to the present invention, the case where the left and right frames of the front cabinet 1 are composed of metal frame members 13 and 14 such as aluminum materials with respect to the side frame members 6 and 7 made of plastic material will be described.
