Description

[Detailed Description of the Invention] The present invention relates to a hinge mounting mechanism for opening and closing a dust cover of a player, etc., and in particular, a hinge shaft is attached to a hinge pocket part formed inside the dust cover by a hinge plate part and a hinge bracket part. The present invention relates to an improvement in a hinge mounting mechanism for opening/closing a dust cover of a player, etc., in which the hinge plate portions of hinges connected via the hinge are inserted and connected.

A hinge attachment mechanism for opening and closing the dust cover is used to attach the dust cover to the cabinet of a player or the like so that the dust cover can be opened and closed.

FIG. 1 is a sectional view showing an example of a conventional dust cover opening/closing hinge attachment mechanism, in which a dust cover 1 is attached to a cabinet 3 by a hinge 2 so as to be openable and closable. The hinge 2 is constructed by connecting a hinge plate portion 2a and a hinge bracket portion 2b via a hinge shaft, and the hinge plate portion 2a is a hinge pocket formed inside the dust cover 1, that is, on the inside of the top surface. The hinge bracket portion 2b is configured to be inserted into the cabinet 3.

FIG. 2 shows a state in which the dust cover 1 is opened, and the dust cover 1 is opened by rotating upward about the hinge shaft 4 as a fulcrum.

With this hinge mounting mechanism for opening and closing the dust cover,
Since the hinge 2 is provided at the end of the dust cover 1, even when the dust cover 1 is in the open state, the dimensions of the rearwardly protruding part of the dust cover 1 are extremely small, so the cabinet 3 cannot be attached to a wall surface 5, etc. Even when placed close together or in contact, the dust cover 1
This has the advantage that it is possible to open the In addition, this hinge mechanism has a hinge plate portion 2 attached to a hinge pocket portion 1b formed inside the dust cover 1.
Since the hinge bracket part 2b is inserted into the cabinet 3 and connected, the hinge 2 is not exposed to the outside, resulting in an excellent appearance.

However, in this dust cover opening/closing hinge attachment mechanism, simply inserting the hinge plate part 2a into the hinge pocket part 1b in the direction along the top surface of the dust cover 1 has a small tensile strength in that direction. Easy to come off. For this reason, conventionally, the hinge plate portion 2a is fixed by using a fixing member such as a screw 6 or a rivet.

Therefore, it is necessary to tap a hole in the hinge plate portion 2a for fixing the fixing member, and a process of fixing with the fixing member is also required. Furthermore, if the dust cover 1 is molded from a brittle material such as resin, extra steps such as selecting the shape of the screw head and controlling the screw tightening torque become necessary. Furthermore, since the head of the fixing member protrudes, there is also a drawback that this space becomes difficult to utilize.

An object of the present invention is to solve the drawbacks of the prior art, and to provide a hinge plate portion of a hinge in which a hinge plate portion and a hinge bracket portion are connected via a hinge shaft to a hinge pocket portion formed inside a dust cover. A hinge mounting mechanism for opening and closing a dust cover that is inserted and connected is easy to manufacture and assemble, and the dust cover and the hinge are arranged in a form in which there are no members protruding from a hinge pocket formed in the dust cover. It is an object of the present invention to provide a hinge mounting mechanism for opening and closing a dust cover of a player, etc., which can be strongly connected.
