2. Description of the Related Art FIG. 5 shows a part of a panel portion of a conventional in-vehicle CD changer, (A) is a front view of the panel portion,
(B) is a sectional view taken along line BB of (A).

[0005] A CD changer 1 for a vehicle shown in FIG. 5 (A) has a housing section formed of a metal chassis (not shown) and a panel section (escussion) 2 made of synthetic resin mounted in front of the housing section. It is composed of In addition, a disk magazine for accommodating a CD, a mechanism for selecting a CD, a drive mechanism for reproducing and driving the CD, and the like are built in the casing. The panel 2 has an opening 3 formed therein, through which the disk magazine loaded with the CD is loaded into the housing.

The upper edge 2A and the lower edge 2B of the opening 3 are formed with guide grooves 2a and 2b extending in the X direction in the figure. Upper edge 4 of slide door 4 made of synthetic resin
A and lower edge 4B have sliding claws 4a and sliding claws 4b
Are respectively formed to protrude. These sliding claws 4a, 4b
Slides in the guide grooves 2a and 2b, so that the slide door 4 is slidable in the X direction.

A stepped portion 3 is provided at the edge of the opening 3 on the X2 side.
a is formed, and a locking portion 3b is formed at the center of the locking portion 3b so as to protrude forward from the apparatus. In addition, the slide door 4 shown in FIG.
A lock claw 4e projecting toward the inside of the apparatus is formed at the end on the side.

When the slide door 4 is moved to the position X2 in the figure, the lock claw 4e is slightly locked by the locking portion 3b, and the opening 3 is closed. When the slide door 4 is moved in the X1 direction from the closed state, the light lock is released and the opening 3 can be opened.

[0007]

In the slide door device shown in FIG. 5, the locking portion 3b formed on the panel portion 3 and the lock claw 4e formed on the slide door 4 are both substantially rigid. There is a structure in which the locking portion 3b close to the rigid body and the lock claw 4e are forcibly fitted. for that reason,
When the slide door 4 is locked in the closed position and when the slide door 4 is moved in the opening direction to release the lock, the load acting on the slide door 4 is large, and therefore, the operation feeling when the slide door 4 is closed and opened is reduced. There are inferior drawbacks.

Further, since the panel portion 3 and the slide door 4 are made of synthetic resin, the distortion of the molding causes the locking portion 3b.
The lock between the lock claw 4e and the lock claw 4e may be too hard or too loose, resulting in a disadvantage that the locked state is not stable.

Also, in order for the slide door 4 to slide, a gap is required in the vertical direction in FIG. 5 (A) at the sliding portion between the sliding claws 4a, 4b and the guide grooves 2a, 2b. Due to this gap, the slide door 4 locked in the closed state rattles up and down, and a rattling sound is generated when the body vibration or the like acts.

A gap is also formed between the upper edge 4A and the lower edge 4B of the slide door 4 and the upper edge 2A and the lower edge 2B of the opening 3. Since the slide door 4 is not biased to any of the above, the slide door 4 moves up and down when the slide door 4 is locked in the closed state, and even while moving in the opening and closing direction, and the position is not stabilized. Therefore, the gap δ1 formed on the upper edge side of the slide door 4 and the gap δ formed on the lower edge side
2 tends to be non-uniform, and has the disadvantage of impairing the appearance of the panel surface.

The present invention solves the above-mentioned conventional problems. When the slide door is closed, the locked state is always stable, and the slide door is locked and unlocked when the slide door is locked and unlocked. It is an object of the present invention to provide a slide door device capable of stabilizing a load acting on a door.

Another object of the present invention is to provide a slide door device capable of preventing rattling of the slide door and stabilizing the vertical position of the slide door.

[0013]

According to the present invention, there is provided an opening formed in a panel, and a sliding door moving between an open position for opening the opening and a closed position for closing the opening. In one of the slide door devices, one of the slide door and the panel is provided with an elastic arm capable of being elastically deformed in a direction intersecting the opening and closing movement direction of the slide door, and the other is provided with the slide door. A convex or concave engaging portion that engages with the elastic arm when moved to the closed position is provided.

[0014] More preferably, the other is provided with a convex or concave locking portion which engages with the elastic arm when the slide door moves to the open position.

In the above means, when the slide door is in the closed position, and more preferably, when the slide door is in the open position, the elastic arm is hooked on the convex or concave locking portion, thereby locking the slide door. Is done. Since the sliding door is locked by the elastic arm being pressed by the locking portion in this manner, the locking force of the sliding door is stabilized, and the sliding door is acted upon when the sliding door is locked and when the locking door is unlocked. The load to be applied becomes constant, and the operation becomes easy.

Further, the locking portion has a convex shape protruding in the direction of the elastic arm, and when the elastic arm is engaged with the locking portion, the elastic force of the elastic arm causes the sliding door to move. Preferably, a biasing force in a direction orthogonal to the opening and closing movement direction is applied to the opening.

In this structure, when the sliding door is locked in the closed state or the opened state, the urging force is applied to the sliding door, so that the locked sliding door does not rattle. In addition, the position of the sliding door with respect to the panel is also stabilized, and the appearance is improved.

In this case, when the elastic arm is disengaged from the locking portion and the slide door moves, the elastic arm does not apply an urging force to the slide door, or the elastic arm applies a biasing force to the sliding door moving. It is preferable that the applied biasing force is smaller than the biasing force applied to the sliding door in the closed position.

With this configuration, the sliding resistance when the sliding door is moved in the opening and closing direction can be reduced, and the sliding door can be opened and closed smoothly.

Alternatively, when the slide door moves in the opening / closing direction, the elastic arm disengaged from the locking portion slides while resiliently pressing the panel or the slide door. An urging force in a direction perpendicular to the opening and closing movement direction may be applied.
As described above, the elastic arm slides while being pressed against the panel, thereby preventing rattling during movement of the slide door.

The elastic arm may be formed of a wire spring or a leaf spring.

Alternatively, the elastic arm may be formed of a synthetic resin material so as to be elastically deformable. In this case, the elastic arm may be formed integrally with the slide door.

As shown in FIG. 4, a locking portion 14 and a locking portion 15 projecting downward from the upper inner wall 12 in a triangular shape are formed on the panel portion 11 at intervals in the X direction. . The locking portion 14 is an open locking portion, and the locking portion 15 is a closed locking portion. An inclined surface is formed on both sides in the X direction of the locking portions 14 and the locking portions 15.

As shown in FIG. 3, the stepped portion 23 of the slide door 20 is formed with a hooked recess 23b which is pulled out in the vertical direction (Z direction) in the figure. On the closed side (X2 side) of the rear surface of the slide door 20, a boss 27 and a locking hole 28 protruding in the rear direction (Y1 direction) are formed. Then, the locking recess 23b, the boss 27 and the locking hole 28
A spring member 30 is provided between them.

The spring member 30 is formed by bending a metal wire spring. One end is a fixed part 30a, the other end is an elastic arm 30b, and the part between the fixed part 30a and the elastic arm 30b is bent. The fulcrum 30c is the center. The spring member 30 is mounted in a state where the fixing portion 30a is inserted into the locking hole 28 and the fulcrum portion 30c is interposed between the boss 27 and the step portion 23. At this time, the elastic arm 30
b is slightly bent in the Z2 direction and is hooked on the hooking recess 23b, so that the elastic arm 30b is projected upward from the upper edge 21 of the slide door 20. Therefore, in a state where the spring member 30 is attached to the slide door 20, the elastic arm 30b is elastically deformable in the counterclockwise direction in FIGS. 3 and 4 with the contact portion between the fulcrum portion 30c and the boss 27 as a fulcrum. is there. Further, the bending of the elastic arm 30b in the clockwise direction is restricted by the engaging recess 23b.

Hereinafter, the operation of the slide door device will be described. Open the slide door 20 (X1 direction)
, The end of the slide door 20 on the X1 side in the drawing comes into contact with a stopper (not shown) in the panel section 11, the slide door 20 reaches the open limit position, and the opening 11A is opened. At this time, as shown in FIG.
The elastic arm 30b of the spring member 30 climbs over the open side locking portion 14 formed on the inner wall 12 of the panel portion 11, is locked on the X1 side inclined surface of the locking portion 14, and
0 is in the light lock state. At this time, the distal end portion 30b1 of the elastic arm 30b gives an upward elastic force F1 to the inclined surface of the locking portion 14, and the reaction force thereof causes the sliding door 20 to face the downward direction in a direction opposite to the elastic force F1. Energizing force is given. Further, the component of the elastic force F1 in the X1 direction acts on the slide door 20 by the inclined surface of the locking portion 14, so that the slide door 20 is stabilized in the open state.

As shown in FIG. 4C, the sliding door 2
0 is moved in the closing direction (X2 direction), the end surfaces of the step portions 23 and 24 of the slide door 20 are moved to the panel portion 1.
1, the slide door 20 reaches the closing limit position, and the opening 11A is closed. At this time,
The elastic arm 30b of the spring member 30 is
5, the sliding door 20 is lightly locked by being pressed by the inclined surface on the X2 side of the locking portion 15. In this closed state, the distal end portion 30b1 of the elastic arm 30b applies an upward elastic force F2 to the slope on the X2 side of the locking portion 15. Therefore, the slide door 20 is urged downward by the reaction force. Further, due to the inclined surface of the locking portion 15, a component force of the elastic force F2 in the X2 direction acts on the slide door 20, so that the slide door 20 is stabilized in the closed state.

When the slide door 20 moves to the open position shown in FIG. 4A and the closed position shown in FIG. 4C, the distal end portion 30b1 of the elastic arm 30b is elastically deformed while the locking portion 14 or Get over 15 slopes. Therefore, when the slide door 20 is lightly locked between the closed position and the open position, and when the lock is released, the resistance force applied to the slide door 20 depends on the elastic force of the elastic arm 30b and the inclination angle of the inclined surface. Will be decided
A stable and moderate resistance always acts on the sliding door 20.

When the slide door 20 is in the closed position and in the open position, a downward urging force is applied to the slide door 20 by the reaction force of the elastic pressures F1 and F2. When the slide door 20 is not rattled in the vertical direction and the vehicle body is vibrated, it is possible to prevent the rattle sound from being generated.

When the sliding door 20 is closed, the sliding door 20 is urged downward by the urging force and its position is stabilized, so that the upper edge 21 and the opening of the sliding door 20 shown in FIG. 11A, the gap δa with the upper edge 11A1, the lower edge 22 of the slide door 20 and the opening 1
The gap δb with the lower edge 11A2 of 1A is always stable without fluctuation. Therefore, if the dimensions of the panel portion 11 and the slide door 20 are determined so that the gaps δa and δb always have the same size, δa and δb will always be the same when the slide door 20 is closed. The appearance becomes better.

As shown in FIG. 4B, while the sliding door 20 moves in the opening and closing direction,
The distal end portion 30b1 of the zero elastic arm 30b slides on the upper inner wall 12 of the panel portion 11. At this time, it is preferable that the elastic force F0 applied to the inner wall 12 by the distal end portion 30b1 is set to be almost zero. That is, when the spring member 30 is attached to the slide door 20, the elastic arm 30b
