[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure for a disc player in which a disc loading portion having a recessed opening is formed on the upper surface of a player case, and a door for opening and closing the disc loading portion is provided.

[0002]

2. Description of the Related Art As shown in FIG. 5, a CD player used as a game device or an audio device is provided with a compact disc loading section B having a recessed opening on the upper surface of a player case A and a compact disc loading section. A door C is attached to the part B, and the setting and resetting of the compact disc are performed in the open state of the door C. In this case, as a hinge structure of the door C, as shown in FIG. L-shaped arms D, D provided with hinge pins E, E on both sides of the base protrude, and these arms D, D are attached to a hinge bracket F, which is attached to the inner lower surface of the player case as shown in FIG. F so that it can be opened and closed.

[0003]

However, according to the above-mentioned conventional hinge structure, the arms D, D need to be sunk under the player case A, and the arms D, D hinder the opening and closing of the door C. In order to prevent this, a relatively large hole G for inserting an arm portion must be provided in the concave opening on the upper surface of the player case A, which is difficult in terms of design, and the hinge pins E, E are hinged. Bracket F,
When the arm parts D, D are inserted into the holes G, they must be bent in the direction of the arrow in FIG.

Accordingly, an object of the present invention is to provide a hinge structure in which the design of the above-described disc player is improved and the door can be easily mounted.

[0005]

That is, the present invention relates to a door for a disc player in which a disc loading portion having a recessed opening is formed on the upper surface of a player case and a door for opening and closing the disc loading portion is provided. A hinge pin is provided on both sides of a base serving as an opening and closing fulcrum of the door, and a hinge pin insertion groove perpendicular to the hinge pin is formed in the recessed opening, and these hinge pin insertion grooves are A hook portion for retaining formed near the entrance and a pin fitting portion formed on the inner side of the groove with respect to the hook portion are provided,
Further, the retaining hook portion is formed on a movable member that is elastically deformed with the inner side of the groove as a fulcrum when the hinge pin is inserted, and the inserted hinge pin is fitted into the pin fitting portion by an elastic reaction force of the movable member. It is characterized by having been done as follows.

[0006]

According to the above structure, when the hinge pin is inserted into the hinge pin insertion groove, the retaining hook portion made of the movable member is lowered downward by the insertion pressure, whereby a force for pushing the hinge pin upward is applied, and the hinge pin is applied. The pin is automatically fitted into the pin fitting portion, and the door can be opened and closed with the fitted portion as a fulcrum.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a CD player 1, in which a compact disc loading section 3 having a recessed opening is provided on the upper surface of a resin player case 2, and the same resin door for opening and closing the compact disc loading section 3 is provided. 4 is attached.

In this case, a swelling portion 5 is formed at the base of the door 4 on the hinge side, and a pair of hinge pins 6 and 6 are integrally protruded from both sides of the swelling portion 5 in a coaxial state. You. On the other hand, the compact disc loading section 3 is formed with a recess 7 into which the bulging section 5 of the door 4 is fitted,
Hinge pin insertion grooves 8, 8 perpendicular to the hinge pins 6, 6 are formed on both inner sides of the concave portion 7.

As shown in FIGS. 3 and 4, these hinge pin insertion grooves 8, 8 have an entrance 9 provided on the compact disk loading section 3 side, and have grooves near the entrance 9. A retaining hook portion 10 formed on the lower surface and a pin fitting portion 11 formed on the upper surface of the groove on the inner side of the groove with respect to the hook portion 10 are provided. The hinge pin 6 is formed on the movable member 12 that is elastically deformed downward with the inner side of the groove as a fulcrum when the hinge pin 6 is inserted, and the inserted hinge pin 6 is fitted into the pin fitting portion 11 by the elastic reaction force of the movable member 12. It has been done. The height of the hinge pin insertion groove 8 when the hinge pin 6 is not inserted is sufficiently smaller than the pin diameter of the hinge pin 6, and the tip of the movable member 12 is
The hinge pin 6 is formed on a tapered surface 13 for guiding when the hinge pin 6 is inserted.

According to such a hinge structure of the door 4,
The hinge pin 6 is inserted from the state of FIG.
When inserted from the inlet portion 9, the height of the hinge pin insertion groove 8 is smaller than the pin diameter as described above.
The movable member 12 is lowered by the insertion pressure of the hinge pin 6 that is guided and entered by the tapered surface 13, whereby the hinge pin 6 gets over the retaining hook portion 10 and enters the hinge pin insertion groove 8.
A force is applied to the hinge pin 6 to push the movable member 12 upward, so that the hinge pin 6 is automatically fitted into the pin fitting portion 11, and the door 4 can be opened and closed with the fitted portion as a fulcrum.

Therefore, the door 4 can be mounted only by inserting the hinge pin 6 into the hinge pin insertion groove 8, and the door mounting workability is improved. Further, unlike the conventional example, it is not necessary to provide an irregular opening on the upper surface of the compact disc loading section 3, and the design is improved.

Once the hinge pin 6 is inserted into the insertion groove 8, it is retained by the fitting portion 11. However, in order to further enhance the retaining property, the bulging portion 5 of the door is shown by a chain line in FIG. Such a retaining hook 14 is protruded, and a slit 15 into which the hook 14 can enter may be formed on the case 2 side. Of course, in this case hook 14
As the hinge pin 6 enters the insertion groove 8, the hinge pin 6 enters and engages with the slit 15 while bending. The slit 15 is an elongated slit as shown in FIG. 3 so as to allow the hook 14 to pivot even when the door 4 opens and closes.

[0014]

As is apparent from the above description, according to the present invention, when the hinge pin is inserted into the hinge pin insertion groove, the retaining hook portion made of the movable member is lowered downward by the insertion pressure, and thereby the hinge pin is inserted. The hinge pin is automatically fitted into the pin fitting portion by applying a force for pushing upward, and the door can be opened and closed with the fitted portion as a fulcrum. Therefore, the door needs only to be inserted by inserting the hinge pin into the hinge pin insertion groove, and the mounting workability is improved.

Further, since the hinge pin is inserted into a hinge pin insertion groove formed on the lower surface of the player case to control the opening and closing of the door, it is necessary to provide an unusual opening for inserting a hinge arm on the upper surface of the disc loading portion. Disappear and the design gets better.
