Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the provision of a storage box structure for use in a structure having a mounting space inside such as a front panel surface or a cabinet surface of an automobile.

2. Description of the Related Art Boxes for storing parts required for driving or operation are provided in a front part of an automobile or operation parts of various machines so as to be drawn out.

Similarly, storage boxes for components required for handling operations are provided so as to be able to be pulled out in the operating part of various electric equipment and the operating part of audio equipment such as audio.

Also, various cabinets are provided with a large number of storage boxes in the same manner, and these boxes are pulled out of these cabinets by one-touch operation for easy and reliable removal and use of parts. Or it was configured to be able to be pushed back and stored.

In a structural box that is protruded from a cabinet or the like by one-touch operation and stored and locked inside the cabinet or the like in a pushed back state, this storage box is protruded from the mounting surface of the cabinet or the like by various spoon rings or the like. In many cases, the storage box is urged toward the outside, and one of them has a structure in which the storage box is resiliently pushed from the rear side by a coil spring provided in a direction in which the storage box protrudes from a mounting opening of a cabinet or the like. The other one has a structure in which the storage box is pulled using a coil spring in a direction in which the storage box protrudes from a mounting opening of a cabinet or the like.
As still another urging method, a gear rotating with a spiral spring and a rack meshing with this gear are provided on the side of the storage box and the side of the cabinet or the like, and the storage box is moved by the urging force of the spiral spring. There is a structure that projects forward from a mounting opening of a cabinet or the like.

[Problems to be Solved by the Invention] However, in the conventional method of using the storage box by repelling and pushing back and storing by one-touch operation, the urging force of the spring urging the storage box is reduced from the cabinet or the like. It is strong in the initial operation of popping out the storage box, and tends to gradually decrease as the storage box is flipped out.

For this reason, the storage box mounted on the cabinet or the like has a disadvantage that it shows a rapid movement in the initial stage of being pushed out of the cabinet or the like by the urging of the spring, and the movement becomes slow slowly in the later stage of the pushing out.

The magnitude of the range of change of the biasing action by the spring of the storage box is difficult to stably store various parts stored in this storage box, and it is intuitive when flipping the storage box Abrupt abruptness is inevitable,
In addition, the sensory frustration at the end of splashing was inevitable.

Also, the urging force of the spring which is extremely different depending on the state of the storage box being repelled is, for example, the urging force of the spring on the storage box at the position where the storage box is repelled from the cabinet or the like is weak, and the cabinet or the like There is a problem that it is difficult to stably maintain the biased state of the storage box protruding from the storage box by this spring. Also, when pushing the storage box into the cabinet or the like and locking it, it is necessary to store and lock the storage box in the cabinet or the like with the strongest force of the spun ring used for biasing, and There was a problem that adverse effects such as settling occurred.

The storage box structure according to the present invention eliminates inconvenience in the conventional storage box structure such as a small container, an ashtray, etc., and resists the repulsion by the spring of the storage box and the bias of the spring. Pushing is performed with a substantially uniform force and can be performed with a smooth operation, and the posture of the storage box at the position where the storage box is protruded is reliably maintained.
Further, it is an object of the present invention to provide a storage box structure capable of forming a reasonable locking state at the push-lock position of the storage box.

[Means for Solving the Problems] The storage box structure according to the present invention achieves such an object, and the storage box structure according to claim 1 is provided on an opening portion of a front panel or a cabinet of an automobile. An outer case A to be assembled, and an inner case B which is incorporated in the outer case A and at least a part of which can freely move out of the outer case A, is constructed.

It is configured to be locked against the force by the second locking means k.

Further, the storage box structure according to claim 3 is the storage box structure according to claim 1 or 2, wherein
, A rotatable sliding portion 1c is rotatably provided on the free end side.

[Operation] In the storage box structure according to the present invention, on the back side of the inner case B assembled to the outer case A and made to be able to come and go, it is pivotally supported by the inner bottom portion of the outer case A, In addition, the free end side of the rotating arm 1 that is elastically biased toward the opening side of the outer case A abuts, and the inner case B is biased toward the opening side of the outer case A by the rotating arm 1. doing.

As a result, until the rotation trajectory drawn by the rotation arm 1 and the direction of the horizontal or arc-shaped slidable path of the inner case B coincide with each other, the rotation residing on the back side of the inner case B is performed. A force corresponding to the difference between the directions of the respective trajectories is generated in the pressing force of the arm 1, and the pressing force of the rotating arm 1 is reduced by the pressing force corresponding to the component force. Further, when the rotation locus drawn by the rotating arm 1 and the direction of the horizontal or arc-shaped sliding path of the inner case B coincide with each other, the component of the pressing force on the rotating arm 1 is lost, and The urging force of the torsion coil spring 2 acting on the moving arm 1 acts on the inner case B as a pressing force.

On the other hand, the urging force of the torsion coil spring 2 urging the rotating arm 1 is strong in the initial stage of the pushing of the inner case B, and tends to gradually decrease toward the end of the pushing. In the relationship between the rotation locus drawn by the moving arm 1 and the direction of the horizontal or arc-shaped slidable path of the inner case B, the torsion coil spring 2 becomes gradually closer as the direction approaches.
Acts on the inner case B so as to be reduced.

The case B can be stored and locked in the outer case A.

Further, the urging force of the rotating arm 1 abutting on the rear side of the inner case B housed and locked in the outer case A generates a horizontal or arc-shaped trajectory of the sliding movement of the inner case B. A component force corresponding to the difference in the direction formed by the rotation locus of the moving arm 1 is generated, and the pressing force on the inner case B is reduced by this component force.

Furthermore, when the inner case B is protruded from the outer case A, the horizontal or arc-shaped trajectory of the sliding of the inner case B and the direction of the rotation trajectory of the rotating arm 1 are made to match or as close as possible. No component force is generated in the pressing force of the rotating arm 1 against the inner case B, and the inner case B is kept in the protruding state by receiving all the urging forces of the rotating arm 1. Further, the feeding of the inner case B sent out from the outer case A in this manner is regulated by the guide means l, l '.

The convex ridge 10 is fitted and guided in the guide groove 4 on the bottom surface of the outer case A which constitutes the other of the guide means l '. , The inner case B does not rattle or shake in the width direction. Further, since the rotating arm 1 pushes the rear side of the inner case B with an arc-shaped locus drawn by the rotating arm 1, the ridge 26 of the inner case B slides on the upper surface side of the guide groove 3 in a pressed state. The inner case B is prevented from rattling in the vertical direction when the inner case B moves in and out.

Further, the gear 8 interlocked with the oil damper 5 is meshed with the rack 9 on the surface of the ridge 10 of the inner case B, so that the inner case B can be smoothly operated.

Further, since the inner case B and the ashtray C are separately configured to facilitate the attachment and detachment of the ashtray C, the inner case B
Can be used as an ashtray or as another small container.

Further, in the above embodiment, the inner case B is configured to operate by drawing an arc-shaped trajectory with respect to the outer case A. Even if the opening D 'of the panel D or the like is inclined or curved, the inner case B may not move. The decorative front plate 25 of B can be accommodated on the surface of the panel D or the like without a sense of incongruity, and the width of the storage box structure on the depth side can be reduced.

Note that a structure in which the inner case B is slid horizontally without moving the inner case B relative to the outer case A in an arc-shaped locus as in this embodiment may be employed.

Next, the relationship between the operation of the inner case B of the storage box and the rotating arm 1 will be described. FIG. 11 is a typical example thereof, which is a point t where the locus mn of the rotating arc of the inner case B and the locus nn of the rotating arc at the position where the rotating arm 1 contacts the inner case B. The center s' of the rotating arm 1 is positioned on a line yy connecting the center point s of the rotation arc of the inner case B.

In this state, the urging force f of the turning arm 1 is changed according to the difference between the direction of the turning locus nn drawn by the turning arm 1 and the direction of the locus mm drawn by the turning arc of the inner case B. A component force f 'is generated. The component force f' is represented by a rotation locus nn drawn by the rotary arm 1 and a rotation locus m drawn by the inner case B.
As the direction of −m gradually approaches the same direction,
The component force f 'becomes smaller, and at a point t where the direction of the locus nn drawn by the rotating arm 1 and the direction of the rotation locus mm drawn by the inner case B coincide with each other, the component force f' becomes zero, and The urging force of the moving arm 1 acts as a pressing force for the inner case B in the state in which the urging force is maintained.

As a result, the urging force of the torsion coil spring 2 that elastically urges the rotating arm 1 in the rising direction gradually decreases with the rising of the rotating arm 1, whereas the inner case by the rotating arm 1 is reduced. Increase the bias on B,
The inner case B is extruded at a uniform speed,
Even when the inner case B is pushed into the outer case A, the inner case B can be housed and locked in the outer case A with substantially uniform pressing force.

The relationship between the inner case B and the rotating arm 1 is as follows.
A line y connecting the center t of the arc drawn by the rotating arm 1 to the point t where the locus of the arc drawn by the rotating arm 1 contacts the locus of the arc drawn by the inner case B, and the center line s of the arc of the inner case B.
It is preferable to position it on -y or on the side in the biasing direction of the rotating arm 1 with respect to this line yy.

Also, from the point that the pushing speed of the inner case B is kept constant, the line yy
Is preferably set to 90 degrees or less with the locus mm of the arc drawn by the inner case B.

[Effect] The storage box structure according to the present invention has a feature that the operation of the inner case housed in the outer case is smooth and operates at a substantially constant speed because of the characteristic configuration described above. It is possible to provide a storage box with a small difference between the inner case extrusion speed at the beginning of operation and the end of operation.

Also, the urging force of the rotating arm with respect to the inner case pushed into and locked in the outer case against the urging force of the torsion coil spring is appropriately reduced, and the engagement of the inner case in an unreasonable state against the strong urging force is reduced. It does not have to stop.

Further, the rotating arm operates with no component force generated in the biasing force of the rotating arm with respect to the inner case protruding from the outer case, and the inner case protruding from the outer case stabilizes. Posture can be maintained.

Further, since the rotating arm is provided in the outer case in a biased state, the assembling of the biasing means and the assembling of the inner case are particularly easy, and the assembling cost can be reduced.

Further, since the guide means is provided on the outer case and the inner case, it is possible to reliably prevent rattling when the inner case is moved in and out, and to enable smooth sliding of the inner case. Particularly, in the guide means l ', a rack 9 is provided on the ridge 10, and a gear 8 interlocking with the rotation shaft of a shock-absorbing rotating body such as the oil damper 5 is meshed with the rack 9 so that a stable rotation shock is obtained. It has the feature of being made.

According to the second aspect of the present invention, since the free end side of the rotating arm is in contact with the arc-shaped guide rib on the back side of the inner case, stable and smooth sliding of the inner case can be achieved.

Furthermore, according to the third aspect of the present invention, since the rotary arm is provided with a rotatable sliding contact portion that is rotatable, the contact with the inner case is smoothly performed, which further improves the smooth sliding of the inner case. Is what makes it possible.
