The door 10 generally has a rectangular shape that is generally elongated in the transverse direction along the front shape of the tray (not shown), and a plurality of arms 12 having an inner hook shape are integrally formed, and the arms 12 are moved outward. Protruding hinge pins 14 and through holes.

The front panel 30 has an opening that corresponds to the shape of the door 10, and a plurality of brackets 32 and a locking piece 32a are formed at an inner side adjacent to the opening, and the bracket 32 is a spring 20. ) Is provided with a through hole for insertion of the hinge pin (14).

Operation of the front panel door structure of a conventional DVD player having such a configuration is as follows.

The opening of the front panel 30 is normally closed by the door 10, and the door 10 rotates and opens with respect to the panel 30 only when the tray is unloaded for seating or withdrawing the medium.

When the medium is settled or drawn out, the inner surface of the door 10 is pressed by the front side of the tray as the tray is ejected through the opening of the panel 30, and the door 10 is centered on the hinge pin 14. Rotation is open.

The hinge pin 14 is rotatably inserted around the through hole of the bracket 32 while the spring is inserted, and one extension end of the spring 20 is inserted and supported by the through hole of the door arm 12. The other extension end is caught by the catching piece 32a or the bracket 32 or is directly contacted and supported by the inner surface of the panel 30 so that the arm 12 of the door receives elastic restoring force against the inside of the panel 30. The greater the rotation angle of the door 10, the greater the restoring force.

While the tray is unloaded, the door 10 is supported by the tray while being pushed up. As the tray is inserted after the medium is seated or unloaded, the door 10 is returned to its initial position by the elastic restoring force of the spring 20. Thus, the opening of the panel 30 is closed.

The front panel door structure operating as described above fits the spring 20 into the hinge pin 14 of the at least one door arm 12 and inserts the door arm 12 through the opening of the panel 30. After arranging the hinge pin 14 to approach the bracket 32, first, the hinge pin without the spring 20 is inserted through the bracket 32, and then the hinge pin 14 with the spring 20 inserted therein. ) Is assembled by inserting through the through hole of the bracket (32).

However, the process of installing the hinge pin 14 into which the spring 20 is fitted to the bracket 32 is carried out by applying elastic restoring force to the door 10 and the panel 30 while being careful not to detach the spring 20. Precise manual work is required because both ends must be assembled in place.

In addition, even after assembly, the door 10 is axially eccentric due to vibration or shock, so that the hinge pin 14 on the other side is easily detached from the bracket 32, thereby causing the spring to be detached and lost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to eliminate the delicate manual work of installing a spring so that the door receives elastic restoring force against the panel, and at the same time, the door arm is deflected in the rotation axis direction by the impact. To prevent the separation from the bracket, thereby reducing the manufacturing time and cost of the DVD player front panel door structure.

In order to achieve the above object, the present invention provides a front panel having a bracket having a through hole formed therein, and a hinge pin inserted into the through hole of the bracket so as to open and close the opening rotationally. In the front panel door structure of a DVD player including a door having a plurality of arms, the hinge pin has a through hole formed therein, and the panel includes a support having a rod inserted into the through hole to provide an elastic force to return the door. Characterized in that.

As shown in FIG. 4, the front panel door structure of the DVD player according to the present invention includes a plurality of arms 12 in which the hinge pins 14 protrude outwardly and adjoin the through holes 16. Front panel 30 having a door 10, a support 33 on which a rod 33a is disposed to limit the rotational axial movement of the door arm 12 and providing an elastic restoring force, and a bracket 32. It includes.

2 to 4, the door 10 has a shape corresponding to the front surface of the tray, and a plurality of arms 12 protruding in a hook shape are formed at both ends, and the arms 12 are hinges protruding outside. The through hole 16 adjacent to the pin 14 is formed.

The panel 30 has an opening for opening and receiving a tray having a shape corresponding to the door 10 on an inner side thereof, a bracket 32 protruding from a position adjacent to the door arm 12 on both sides of the opening, and a door arm ( A support 33 is formed on the opposite side of the bracket 32 to the arm 12 to limit the rotational axial movement of the 12, the support 33 is a through hole 16 of the arm 12 to provide an elastic restoring force The flexible rod 33a inserted in the) is formed.

The rod 33a is a through hole of the door arm 12 when the door 10 rotates about the panel 30 about a hinge pin 14 rotatably inserted into the through hole of the bracket 32. 16 is formed to a suitable length so as not to be completely separated while applying the elastic restoring force in the inserted state, and a rounding portion is formed at its end to facilitate insertion into the through hole 16.

The operation of the front panel door structure of the DVD player configured as described above is performed as follows.

The arm 12 of the door 10 is disposed adjacent to the bracket 32 through the opening from the front of the panel 30, and is disposed between the bracket 32 and the support 33, and the rod 33a is disposed. The hinge pin 14 is inserted into the through hole of the bracket 32 in a state in which the flexible support 33 is pressed and opened so as not to interfere with the insertion of the door arm 12. Next, when the pressing force applied to the support 33 is released, the rod 33a is inserted through the through hole 16 of the door arm 12 as the support returns to the initial position.

Here, the rod 33a is easily inserted into the through hole 16 because the rounded portion is formed at the end.

When the tray (not shown) is advanced, the arm 12 integrally formed as the tip of the tray presses the rear surface of the door 10 and the pressurized door 10 moves away from the panel 30. Is rotated about the hinge pin 14, the through hole 16, which is eccentric with respect to the hinge pin 12, moves a predetermined distance by drawing an arc around the rotation axis, and is fixed to the support 33 Since the rod 33a is bent as a portion inserted into the through hole 16 moves with the door arm, an elastic restoring force is applied to the inner circumferential surface of the through hole 16.

As a result, the opening of the panel 30 is opened as the door 10 moves away from the panel 30 in an arc, and is kept open because the tray 10 is continuously supported by the tray. .

When the tray enters through the opening of the panel 30, the force applied to the rear surface of the door 10 is released by the tray, and the door arm 12 presses the inner circumferential surface of the through hole 16. By receiving only the action of the elastic restoring force of the rod 33a, the opening of the panel 30 is closed while the door 10 is returned to the initial position while being rotated about the hinge pin 14.

In the assembled front panel door structure according to the preferred embodiment of the present invention, when the hinge pin 14 of the door arm 12 is largely deflected in the rotational axis direction by being subjected to a dropping impact or the like, the hinge pin 14 is inserted. The direction movement is limited by the bracket 32 and the movement in the opposite direction of the insertion direction is limited by the support 33, thereby preventing the hinge pin 14 from being separated from the through hole of the bracket 32.

According to a preferred embodiment of the present invention as described above, opening and closing of the door by the elastic restoring force of the support and the rod formed on the support without installing a separate elastic means such as a spring for applying the elastic restoring force to return the door to the initial position This makes it possible to easily assemble as compared to the delicate manual work for assembling a separate elastic part, and to prevent the deflection of the door after the assembly and the detachment from the panel.

As described above, the front panel door structure of the DVD player according to the present invention replaces an elastic member such as a spring with a flexible rod provided in the panel itself, so that when the spring-loaded hinge pin is mounted on the bracket, Careful attention is to be taken from the hinge pins, eliminating the delicate manual work necessary to insert and install them in the rotational axis direction through the through holes of the brackets. After the installation, the door is axially eccentric to prevent the hinge pin of the door arm from being separated from the through hole of the bracket and thus has an effect of strengthening the assembly.
