Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure for mounting cabinets used for mounting two cabinets.

[0002]

[Prior art]

 In video / audio equipment such as televisions and video-integrated televisions, the cabinet is divided into a front cabinet and a rear cabinet, and these cabinets are connected to each other using mounting screws. In recent years, an integrated molded article of a synthetic resin is often used for each cabinet. When such a synthetic resin front cabinet and a rear cabinet are connected by mounting screws, For example, a method may be employed in which a mounting screw inserted through a mounting screw insertion hole provided in a rear cabinet is screwed into a raw hole of a boss portion provided in a front cabinet while a screw groove is formed.

On the other hand, Japanese Utility Model Publication No. 2-8732 discloses a technique in which a mounting screw is screwed into a raw hole of a boss portion made of a synthetic resin to fix another member to the boss portion. . In addition, Japanese Utility Model Application Laid-Open No. 60-137512 and Japanese Utility Model Application Publication No. 4-7938 disclose a technique for forming an undercut portion of a molded product by using an inclined pin. Then, it has been found that a boss portion having a raw hole on the inner surface side of each outer plate of the front cabinet and the rear cabinet can be integrally formed together with those cabinets.

[0004]

[Problems to be solved by the invention]

 However, when a structure is used in which the front cabinet and the rear cabinet are connected to each other by means of screwing the mounting screws into the raw holes of the synthetic resin boss, the mounting screws are screwed into the raw holes or the mounting screws are inserted through the raw holes. If the removal is repeated several times, the thread groove formed on the raw hole side when the first mounting screw is screwed in gradually becomes loose and becomes a so-called stupid hole, and the mounting screw should be tightened to the specified torque. There was a problem that it became impossible to do.

[0005] The present invention has been made in view of this problem, and in a case where one elementary hole becomes a stupid hole, the other elementary hole can be used for screwing a mounting screw. The purpose is to do.

[0006]

[Means for Solving the Problems]

 In the mounting part structure between cabinets according to the present invention (hereinafter simply referred to as “mounting part structure”), a plurality of holes are provided on one side of the first cabinet and the second cabinet, and the first hole is provided on the other side. When the cabinet and the second cabinet are aligned with each other, each of the plurality of raw holes is provided with a plurality of mounting screw insertion holes respectively facing each other, and each of the raw holes facing each other is provided. The mounting screw inserted into the mounting screw insertion hole is screwed into the element hole at one of the mounting screw setting portions at a plurality of locations including the mounting screw insertion hole and the mounting screw insertion hole. Here, the first cabinet can be, for example, a front cabinet and the second cabinet can be, for example, a rear cabinet.

According to this mounting portion structure, if the hole into which the mounting screw is actually screwed becomes a stupid hole, another mounting screw is set instead of the mounting screw setting portion having the stuck hole. The screw setting part can be selected, and the mounting screw inserted through the mounting screw insertion hole of the selected mounting screw setting part can be screwed into the element hole and tightened.

In the present invention, a boss portion made of a synthetic resin having a plurality of the above-described element holes is provided on one side of the front cabinet and the rear cabinet, and a cylindrical portion fitted to the boss portion is provided on the other side. It is desirable that each of the plurality of element holes is provided with a plurality of the mounting screw insertion holes respectively opposed to each other when the portion is fitted to the boss portion. According to this mounting portion structure, since the cylindrical hole is fitted to the boss portion, the raw hole forming the mounting screw setting portion and the mounting screw insertion hole are aligned, so that the mounting screw is inserted into the mounting screw insertion hole. The mounting screw can be screwed into the raw hole without being eccentric, which has the advantage that the raw hole is less likely to be a stupid hole.

[0009] The advantage as described above is that a contact surface is provided on the inner side of the tubular portion when the tubular portion is fitted to the boss portion, the contact surface being in contact with the end surface of the boss portion. This is more pronounced by adopting a configuration in which a plurality of mounting screw insertion holes are open.

In the present invention, the boss portion is integrally formed on the inner surface of the outer plate on one side of the front cabinet and the rear cabinet via a rib, and the cylindrical portion is formed on the inner surface side of the other outer plate via the rib. The plurality of element holes are integrally formed, and are arranged in parallel along the inner surface of the outer plate on one side, and the plurality of mounting screw insertion holes are arranged in parallel along the inner surface of the outer plate on the other side. Is desirable. According to this, the boss portion becomes wider in the direction along the inner surface of the outer plate on one side, and the cylindrical portion fitted to the boss portion becomes wider in the direction along the inner surface of the outer plate on the other side. The wide boss portion is integrally formed on the inner surface of the outer plate on one side via the rib, and the wide cylindrical portion is integrally formed on the inner surface of the outer plate on the other side via the rib. When the mounting screw inserted into the mounting screw insertion hole is screwed into the raw hole and tightened, the moment when the mounting screw is tightened is less likely to be transmitted to each outer plate via the cylinder or boss. However, it helps to suppress the warp deformation of each outer plate. This point will be described in more detail in the description of the embodiment.

The mounting screw may have a shaft portion having a male screw having a function of carving a screw groove on a hole wall surface of the raw hole, and a flange-shaped projecting head at a base portion of the shaft portion. Desirable. According to this, a step of separately engraving a screw groove in the raw hole before screwing the mounting screw into the raw hole becomes unnecessary.

The front cabinet and the rear cabinet are formed in a substantially polygonal shape as viewed from the rear, and the bosses are provided at each corner on one side of each cabinet, and the corners on the other side are provided. It is desirable that each of the above-mentioned parts is provided with the above-mentioned cylindrical part. According to this, the front cabinet and the rear cabinet can be securely connected at their respective corners.

It is preferable that the number of the raw holes in the boss portion is two, and the number of the mounting screw insertion holes is two. According to this, instead of unnecessarily increasing the number of raw holes and mounting screw insertion holes, another mounting screw setting part is selected instead of the mounting screw setting part having a stupid raw hole, and then selected. The mounting screw inserted into the mounting screw insertion hole of the mounting screw setting part can be screwed into the raw hole and tightened. Further, when a boss having a raw hole or a cylindrical portion having a mounting screw insertion hole is formed by using an inclined pin, the shape of a mold used for the molding is not so complicated.

The front cabinet and the rear cabinet may be video / audio equipment, for example, a television or a video integrated television.
