[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a so-called push-open type storage device attached to an instrument panel or the like of an automobile.

[0002]

[Prior art]

 An example of a conventional push-open type storage device of this type is shown in FIG. 4, in which a storage box B is rotatably supported by a housing H fixed to the instrument panel side. Is always biased in the opening direction by a biasing spring pressure (not shown), the cam member 11 is pivotally provided on the housing H side, and the pin member 13 is provided upright on the storage box B side. When the pin member 13 is locked to the cam member 11, the storage box B can be locked at the closed position in the housing H against the biasing spring pressure. In this state, the storage box B is further stored in the housing H. When pushed, the lock of the pin member 13 with respect to the cam member 11 is released, and the storage box B can be automatically moved from the opening of the housing H in the opening direction.

Further, as shown in the figure, the cam member 11 itself used in such a storage device is an integrally molded product of synthetic resin, and has a cam groove 12 having a series of an inlet 12a, a lock portion 12b and an outlet 12c. It is formed so as to be rotatable on the mounting shaft portion 14 on the housing H side via a torsion spring 15, and is constantly kept at a predetermined pressure by the spring pressure of the torsion spring 15 until it is regulated by the regulation wall portion 16. Biased in the direction. In the figure, 17 is a washer for fixing the cam member 11 to the mounting shaft portion 14, and 18 is a locking wall for locking the end of the torsion spring 15 in cooperation with the locking arm 11b of the cam member 11. It is a department.

When the storage box B is pushed into the housing H during the actual opening / closing operation, the pin member 13 provided on the rear end side of the storage box B abuts on the outer peripheral guide surface 11 a of the cam member 11. Then, the cam member 11 reaches the introduction port 12a of the cam groove 12 while rotating in a direction opposite to the biasing direction of the torsion spring 15. Then, this time, the cam member 11 pivots slightly in the biasing direction by the spring pressure of the torsion spring 15, guides the pin member 13 into the cam groove 12, and at the same time, the storage box B also retracts by the biasing spring pressure. Since the pin member 13 is automatically locked to the lock portion 12b of the cam groove 12, the storage box B can be locked at the closed position in the housing H against the biasing spring pressure. Further, if the storage box B is further pushed into the housing H in this state, the pin member 13 is disengaged from the lock portion 12b of the cam groove 12, and the cam member 11 is allowed to further pivot in the urging direction. After that, if the pushing operation to the storage box B is released, the pin member 13 is automatically disengaged from the cam groove 12 of the cam member 11 while being guided in the direction of the outlet 12c of the cam groove 12. B can be automatically moved in the opening direction from the opening of the housing H by the biasing spring pressure.

[0005]

[Problems to be solved by the device]

 However, in the conventional vehicle storage device, when the storage box B is locked at the closed position in the housing H, the pin member 13 on the storage box B side is locked to the locking portion 12b of the cam groove 12. However, at this time, for example, if another person's vehicle collides from the rear side of the vehicle body or the rear portion of the vehicle body collides with an obstacle or the like at the time of backing, the housing H is caused by this impact force. Although it moves forward together with the vehicle body, the storage box B itself, which is supported by the housing H so as to be openable and closable, tries to stay there because of its urging spring pressure. Causes a separation phenomenon similar to the case where the housing H and the storage box B move in opposite directions. Then, once this separation phenomenon occurs, as shown in FIG. 5, the pin member 13 in the upright state is easily tilted by the impact force, and the tip end side of the cam member 11 is released upward. Therefore, this may cause the pin member 13 to be easily disengaged from the lock portion 12b of the cam groove 12, and the storage box B may be erroneously projected outward from the opening of the housing H by the biasing spring pressure. Was there.

[0006]

Means for Solving the Problems The present invention was developed in order to effectively solve such a conventional problem. A housing is supported by a housing so that the housing can be opened and closed, and the housing is attached. While constantly biasing in the opening direction by the biasing spring pressure, a cam member with a cam groove is provided on the housing side so as to be rotatable, and a pin member that moves in the cam groove of the cam member is provided on the storage box side. By locking the pin member to the lock part of the cam groove, the storage box is locked at the closed position in the housing against the biasing spring pressure, and in this state, the storage box is further stored in the housing. Assuming an automobile storage device configured to release the lock of the cam groove of the pin member with respect to the lock portion by automatically pushing the storage box into the opening direction of the housing, One of the pin member and the lock part of the cam groove Both the adopted a configuration to impart a guide shape for guiding the lock portion of the cams groove at the base direction of the pin member.

[0007]

[Action]

 Therefore, even in the present invention, when the storage box is pushed into the housing, the pin member on the storage box side is locked by the lock portion of the cam groove of the cam member provided on the housing side, and the storage box is opened. It can be locked in the closed position in the housing against the biasing spring pressure, and if the storage box is pushed further into the housing in this state, the pin member will come off from the lock part of the cam groove and the storage box will be closed. It can be automatically moved in the opening direction from the opening of the housing by the biasing spring pressure.

However, in the locked state of the storage box in the closed position, the rear side of the vehicle body collides with another person's vehicle, or the rear portion of the vehicle body collides with an obstacle or the like at the time of backing, and the impact force of In the present invention, even if a separation phenomenon similar to the case where the housing and the storage box move in opposite directions occurs, the guide shape is positively provided to one or both of the pin member and the lock portion of the cam groove. The structure that automatically guides the lock portion of the cam groove in the direction of the base of the pin member ensures that the pin member will not easily come off the lock portion of the cam groove as in the past. It can be prevented.

[0009]

[Embodiment] The present invention will be described in detail below with reference to an illustrated embodiment. The vehicle storage device according to the embodiment is also not specifically illustrated, but is of the conventional push-open type described above. Similar to the above, the housing provided on the instrument panel side supports the storage box so that it can be opened and closed, and the storage box is always biased in the opening direction by the biasing spring pressure, while the cam member can be swung to the housing side. If a pin member is provided on the storage box side and the pin member is locked to the cam member, the storage box can be locked in the closed position in the housing against the biasing spring pressure. If the storage box is pushed further into the housing as it is, the lock of the pin member to the cam member is released, and the storage box can be automatically moved in the opening direction from the opening of the housing by the biasing spring pressure. It is assumed.

Then, in this embodiment, under such a precondition, as shown in FIG. 1, the pin member 3 is inclined at a certain angle in the direction of the lock portion 2b of the cam groove 2 of the cam member 1. 2, or, as shown in FIG. 2, while leaving the pin member 3 upright, a cut-shaped inclined shape 4 is provided on the end edge side of the lock portion 2b of the cam groove 2, or as shown in FIG. As described above, the pin member 3 is inclined in the direction of the lock portion 2b, and at the same time, the cut-shaped inclined shape 4 is provided also to the end edge of the lock portion 2b of the cam groove 2 so that the lock portion of the pin member 3 and the cam groove 2 is When an impact force or a vibration force is applied in the locked state of 2b, the lock portion 2b of the cam groove 2 is automatically moved in the direction of the base of the pin member 3 by the guide action of the respective inclined shapes. It is characterized by being configured to guide. The cam member 1 is the same as the conventional one except that the inclined shape 4 is provided, and thus detailed description thereof will be omitted.

Therefore, even in the vehicle storage device according to the present embodiment, if the storage box B is pushed into the housing H against the biasing spring pressure, the pin member 3 causes the cam groove 2 to move as in the conventional case. The storage box B can be locked at the closed position in the housing H against the biasing spring pressure by automatically locking the storage box B to the housing 2B. When pushed into H 2, the pin member 3 is disengaged from the cam groove 2 via the outlet 2c, and the storage box B 1 is automatically moved in the opening direction from the opening of the housing H by the biasing spring pressure.

However, even in the present embodiment, when the storage box B is in the locked state at the closed position and the rear side of the vehicle body collides with another person's vehicle or the rear portion of the vehicle body collides with an obstacle or the like at the time of backing. The impact force causes a separation phenomenon similar to the case where the housing H and the storage box B are moved in the opposite directions, but in the present embodiment, the pin member 3 or the cam groove 2 is generated. When the impact force is applied due to the fact that the one or both of the lock portions 2b of FIG. 3 is provided with an inclined shape, this time, due to the guide action of the inclined shape, as shown by the phantom line in each figure, in particular, the cam Since the lock portion 2b of the member 1 is forcibly guided in the base direction along the pin member 3, the pin member 3 tilts and the tip portion of the cam member 1 escapes upward as in the conventional case, and both 2b・ There is a concern that the lock of 3 will come off easily. It ’s all gone. Therefore, under the present embodiment, even if the above-mentioned impact force or another vibration force is received, the storage box B reliably stays in the closed position in the housing H and is erroneously moved from the inside of the housing H to the outside. That is, the protrusion can be effectively prevented.

[0013]

[Effect of device]

 As described above, according to the present invention, by adopting the above-mentioned configuration, even if an impact force or a vibration force is applied, the locked state of the pin member and the lock portion of the cam groove can be easily achieved by adopting an extremely simple configuration. Since there is no need to worry about canceling it, it has become possible to eliminate the problems faced by conventional vehicle storage devices.
