Description

  The present invention relates to a television cabinet, and more particularly to a television cabinet having a CRT mounting boss.

  The CRT of the television receiver is attached to a plurality of bosses formed on the back surface of the front plate of the front cabinet of the receiver. Such a CRT mounting boss is formed to extend rearward from the front plate of the front cabinet. The CRT mounting boss is required to have a strength to withstand an impact during a drop test and actual use while supporting a heavy CRT.

  One possible measure for improving the strength of the CRT mounting boss is to increase the thickness of the boss. However, if the boss is thickened, sink marks are likely to occur on the surface opposite to the back surface of the front plate on which the CRT mounting boss is formed, that is, on the front plate surface. If sink marks occur on the front plate surface of the front cabinet, the appearance may be adversely affected and the product may be handled as a defective product. Therefore, the CRT mounting boss cannot be thickened to improve the strength of the CRT mounting boss.

  It is also possible to increase the thickness of the base of the boss in order to improve the strength of the CRT mounting boss. There is a risk of sink marks, which may adversely affect the appearance and be handled as defective products. Therefore, it is necessary to improve the strength of the CRT mounting boss while preventing the occurrence of sink marks.

  Various structures have been proposed for the purpose of improving the strength of resin molded parts such as television cabinets.

  In Patent Document 1, a rear cabinet mounting boss and a holding rib are integrally formed on the inner surface of a front cabinet of a television cabinet, and the holding rib and the CRT guide rib are connected. In addition, the rib base portion is thinned to prevent sinking of the cabinet outer surface, and the portion away from the root portion is thickened to improve strength.

  In Patent Document 2, a triangular structure is formed by connecting three cylindrical posts with plate-shaped pieces around a CRT mounting rib formed on the inner surface of a front cabinet of a television cabinet. Reinforcing ribs are provided on the shaped structure. Thereby, even if a large load or impact is applied to the front cabinet, whitening of the synthetic resin around the CRT mounting boss can be prevented.

  In Patent Document 3, the resin flow is generated by adjusting the thickness near the base of the boss portion in the resin molded product, and the orientation of the filler flowing in the boss portion and the filling flowing in the bottom surface adjacent to the boss portion Prevents the orientation of the material from being orthogonal. Specifically, shrinkage is reduced by reducing the thickness near the base of the boss, so that the occurrence of sink marks can be prevented at the base of the boss, and by increasing the thickness near the base of the boss, It is possible to prevent the occurrence of welds at the protrusions and to improve the strength.

  Patent Document 4 deals with a configuration for preventing sink marks and warpage caused by curing of the resin, which occurs in a photo-curable resin mold. The box frame of the mold is thinly formed of a low heat resistant resin, and a large number of reinforcing ribs are integrally formed on the back surface thereof in a lattice shape and filled with a backing material. With this structure, the occurrence of sink marks and warping after curing of the photo-curing resin is prevented, and the strength is improved.

  In patent document 5, the synthetic resin molded product which prevents the sink of a thick part by internal foaming is handled. The internal foaming is generated by providing a plurality of reinforcing protrusions and injecting and filling a melted raw material in which a foaming agent is mixed into a mold cavity. Volume expansion occurs due to this foaming, and shrinkage of the raw material accompanying cooling is corrected, so that occurrence of sink marks can be prevented.

  In patent document 6, the intensity | strength of a panel is improved by combining two panels injection-molded in the stack metal mold | die. Each of these panels is formed with a grid-like rib, and a boss is formed at the intersection or in the middle of the rib.

  Patent Document 7 describes a configuration in which a plurality of CRT mounting bosses extending substantially horizontally toward the rear are provided inside the four corners of the front cabinet in order to mount the CRT.

  Patent Document 8 describes a configuration in which a plurality of substantially rectangular ribs are integrally formed on an inner wall surface of a front cabinet, and a CRT mounting boss and a post are connected by these ribs.

  Patent Document 9 describes a configuration for increasing the strength against the load of the bottom plate of the container container, particularly the rigidity against deflection and the like. On the back surface of the bottom plate of the container container, that is, the outer wall of the bottom surface of the container container, lattice-like ribs regularly connected in the vertical and horizontal directions are formed, and the strength against the load on the bottom plate is improved by the ribs. In addition, a structure in which lattice-like ribs have a hexagonal shape is described.

  Patent Document 10 describes an automobile trim that is integrally resin-molded so that ribs are arranged in a hexagonal shape.

Patent Document 11 describes a shelf board used when firing a ceramic product. On the shelf plate, ribs arranged in a triangular shape are formed for the purpose of preventing the ceramic product placed thereon from coming off.

As described above, in Patent Document 1, since the contact area between the boss and the holding rib is small, there is a problem that the contact portion between the boss and the rib is easily cracked during the drop test. In Patent Document 2, the boss and the triangular structure are connected by a rib. However, since the contact area between the rib and the boss is small, there is a problem in that the contact portion between the boss and the rib is likely to be cracked during a drop test. . In Patent Document 3, although the strength is improved by adjusting the thickness of the base portion of the boss portion, sinking may occur on the surface of the cabinet when the thickness of the base portion is increased. Conversely, when the thickness of the root portion is reduced, the strength cannot be improved even if the occurrence of sink marks can be prevented. In Patent Document 4, grid-shaped reinforcing ribs are formed and a backing material is filled to prevent the occurrence of sink marks and warpage of the thin box-shaped frame body and to improve the strength. The relationship between the thickness of the boss for use and the occurrence of sink marks is not described, and such a structure cannot be applied as a measure for preventing sink marks when the CRT mounting boss is strong. Also in patent document 5, although the sink of a thick part is prevented by foaming, since thickness is not thickened, it cannot be said that the improvement of intensity | strength is enough. And in patent document 6, although the grid-like rib is formed in a panel and the boss | hub is formed in the intersection of a rib or in the middle, since the contact area of a boss | hub and a holding rib is small, at the time of a drop test, a boss | hub and rib There is a problem that cracks are likely to occur at the contact portion.

In the structure described in Patent Document 8, the CRT mounting boss is connected to the post by a rib. However, since the contact area between the boss and the rib is small, the contact portion between the boss and the rib is cracked during a drop test. There is a problem that it is easy. In the container container described in Patent Document 9, the height of the rib is not specifically mentioned, and the relationship with the boss is not described. That is, Patent Document 9 does not describe a structure that needs to be configured so that there is no sink in appearance according to the thickness of the boss, such as a reinforcing structure of a CRT mounting boss. The structure described in Patent Document 10 achieves both ensuring of shock absorption and prevention of sink marks on the surface by the rib formed on the back surface of the trim for automobiles. There is no description of a structure that needs to be configured so that there is no sink in appearance according to the thickness of the boss. In the structure described in Patent Document 11, ribs arranged in a triangular shape are provided for the purpose of preventing slipping off, but there is a sink on the appearance according to the thickness of the boss, as in the reinforcement structure of the CRT mounting boss. There is no description of structures that need to be constructed so that they do not occur.
