Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to various storage devices provided on an instrument panel or the like of an automobile, and more particularly to improvement of a storage device with a safety function.

[0002]

[Prior Art]

 As a conventional storage device with this type of safety function, there is, for example, the one shown in Japanese Utility Model Laid-Open No. 25332/1990. Although not specifically shown, the conventional storage device supports a storage box in a housing provided on the instrument panel side so that the storage box can be opened and closed, and the storage box is always opened via a biasing spring pressure. While urging, a cam member having a cam groove is pivotally provided on the housing side, and a pin member that moves in the cam groove of the cam member is provided on the storage box side, and the pin member is attached to the cam groove of the cam member. When locked in the lock part, 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 in this state, the cam groove of the pin member Assuming that the locking box is released and the storage box can be automatically moved in the opening direction from the opening of the housing, a guide piece is integrally extended to the rear end side of the cam member. Inertia on the guide piece The weight body for slide is slidably arranged, and the weight body is pulled toward the rear end portion of the cam member by a tension spring, while allowing the end portion of the weight body body to project into the corresponding portion of the housing. The lock cylinder is provided.

Therefore, in the storage device with a safety function having such a structure, when the storage box is normally used, the storage box is pushed into the housing, and the pin member interlocks with the cam. While rotating the member in a predetermined direction, the member is locked in the lock portion of the cam groove, and the storage box is locked at the closed position in the housing against the biasing spring pressure. If is pushed further into the housing, the locking of the cam groove of the pin member with respect to the lock portion is released, and the cam member is allowed to pivot in the unlocking direction. Therefore, it is possible to automatically move in the opening direction by the biasing spring pressure.

However, in the locked state of the storage box in the closed position, when a large inertial force acts at the time of collision of the vehicle or sudden braking, the traction force of the tension spring is resisted against the guide piece of the cam member. The end of the inertial response weight body that is placed at the end protrudes into the lock cylinder to prevent the cam member from swinging in the unlocking direction, which causes the storage box to accidentally come out of the housing opening. It is prevented from projecting in one direction. Therefore, under the conventional storage device, even if the operation direction for unlocking the storage box in the closed position is the same as the direction of the inertial force generated at the time of a collision, the safety function described above Due to the action, the storage box does not accidentally project outward from the opening of the housing, so that there is no fear of damaging the driver or passengers.

[0005]

[Problems to be solved by the device]

 However, the conventional storage device requires an additional inertial response weight body, which is separate from the cam member, in order to obtain a safety function of preventing the storage box from projecting outward due to the action of inertial force. In addition, a guide piece is integrally extended to the rear end side of the cam member, and the separate weight body is arranged on the guide piece by applying the pulling force of the tension spring. Since it is necessary to separately form a lock cylinder on the housing side that allows the end of the housing to enter, the number of parts will naturally increase and the storage device itself will become complicated and large. As a result, the number of assembling steps increased, and the workability of assembling deteriorated, which was a major problem. Also, in the conventional storage device, when the lock release stroke of the storage box is short, the cam member swivels in the unlocking direction before the inertial response weight body moves on the guide piece, and the storage box I couldn't deny that I accidentally project it outside, so I hate it because it lacks reliability.

[0006]

[Means for Solving the Problems]

 The present invention was developed in order to effectively solve the problems of the conventional storage device with a safety function. A storage box is rotatably supported by a housing, and the storage box is supported by a spring pressure. The cam box is provided to the housing side so that it can be swung, the pin member is provided on the storage box side, and the pin member is locked to the lock portion of the cam member to store the storage box. Is locked at the closed position in the housing against the spring pressure, and in this state, the storage box is further pushed into the housing to release the locking of the pin member to the lock part of the cam member, Assuming an automobile storage device configured to automatically move the storage box in the opening direction from the opening of the housing, the above-mentioned cam member is provided with a weight necessary as an inertia response body, and the cam also serves as the inertia response body. Member While supporting it so that it can move in the opening and closing direction of the storage box, the cam member is always urged in the opening direction of the storage box by the spring pressure of the balancing spring, and the cam member is moved only when inertial force is applied. We adopted a configuration that moves the storage box together with the storage box in the closing direction.

[0007]

[Action]

 Therefore, even in the case of the present invention, when it is used for normal use, the spring pressure of the balance spring prevails, so if the storage box is pushed into the housing, it is provided on the storage box side. The pin member can be locked to the lock part of the cam member provided on the housing side to securely lock the storage box in the closed position inside the housing against the biasing spring pressure, and in this state If the storage box is pushed further into the housing, the pin member will disengage from the lock part of the cam member, allowing the cam member to pivot in the unlocking direction. It is possible to automatically move in the opening direction from the opening.

However, in the present invention, when the storage box is locked in the closed position and an inertial force larger than the spring pressure of the balancing spring acts at the time of a vehicle collision or sudden break, etc. The cam member that also serves as the inertial actuator moves in the closing direction of the storage box against the spring pressure of the balancing spring.At this time, the storage box itself moves in the closing direction together with the cam member. The pin member is reliably prevented from moving out of the lock part of the cam member, and as a result, the cam member cannot pivot in the unlocking direction, and the storage box is closed in the housing. No more worrying about accidentally protruding outward from inside the housing.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. A vehicle storage device with a safety device according to the embodiment has the same basic structure as that of a conventional device, and a known technique in the field. By using it, the housing provided on the instrument panel side is supported so that it can be opened and closed, and the storage box is always biased in the opening direction via the biasing spring pressure, while the housing is provided with a cam groove. If the cam member is provided 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 and the pin member is locked to the lock portion of the cam groove of the cam member, the storage box Can be securely 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 locking of the cam groove of the pin member with the lock part To release the cam member lock By allowing pivoting of the release direction, it is a storage box as a premise of the constitution that can be automatically moved to the opening direction from the opening of the housing in pressure it if biased above.

However, the present embodiment does not exert the safety function by using the inertial response weight body separately formed as in the related art and its accessories, and the cam member itself is used as an inertial response body. It was developed by paying attention to a new idea in which the necessary weight is positively applied and the cam member itself also serves as an inertial response body. As a method of giving a necessary weight to this cam member, the cam member itself is molded with a heavy metal material, or when the cam member is molded with a synthetic resin material, the cam member made of resin is used. It is assumed that a heavy object is assembled by insert molding or a known fixing means. However, in the drawings, a cam member formed by a heavy metal material is shown.

Explaining this concretely, the heavy cam member 1 that also serves as the inertial responder moves the pin member P provided on the side of the storage box B as in the conventional case, as shown in FIG. It has a cam groove 2 for guiding and is pivotally supported by a mounting shaft 5 on the housing H side through a washer 6 and a torsion spring 7, and is always biased in a predetermined direction by the spring pressure of the torsion spring 7. However, in the present embodiment, in addition to this, a fitting hole 3 into which the mounting shaft portion 5 is fitted is formed in the rear end portion of the cam member 1 in the shape of an elongated hole, and the fitting hole 3 is formed. By utilizing the elongated hole shape of the hole 3, the cam member 1 is supported so as to be movable with respect to the housing H 1 in the opening and closing direction of the storage box B, while the rear end portion of the cam member 1 and the corresponding side wall surface of the housing H 1. A compression spring 8 for balance is provided between The spring pressure of the balance compression spring 8 constantly elastically urges the cam member 1 in the opening direction of the storage box B so that the cam member 1 is stored only when a large inertial force acts. A configuration is adopted in which the storage box B is moved together with B in the closing direction. In the figure, 9 is a stopper wall portion that regulates the turning biasing position of the cam member 1, and 10 is a locking wall portion that cooperates with the arm portion 1a of the cam member 1 to lock the end portion of the torsion spring 7. Is.

Therefore, even in the case of the storage device having such a configuration, when the storage device is used for normal use, the storage box B is housed due to the prevailing spring pressure of the compression spring 8 for balancing. If the pin member P provided on the rear end side of the storage box B is pressed against the first guide portion 4a of the cam member 1 by pushing it against the biasing spring pressure (not shown) into the ring H. When the cam member 1 comes into contact with the second guide portion 4b of the cam member 1 while rotating the cam member 1 against the spring pressure of the torsion spring 7 and comes into contact with the second guide portion 4b of the cam member 1, this time, the cam member 1 Is pivoted slightly in the biasing direction by the spring pressure of the torsion spring 7, so that the pin member P is introduced into the cam groove 2. At this time, the storage box B is also biased by the biasing spring pressure. As it retreats, this causes the pin part material to P automatically engages with the lock portion 4c of the cam groove 2 to reliably lock the storage box B in 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 P is disengaged from the lock portion 4c of the cam groove 2, and the cam member 1 is further biased (lock unlocking direction). 4), the pin member P is guided by the inclined third guide portion 4d as shown in FIGS. 4 and 5, and the cam member 1 is rotated. Since it is automatically disengaged from the cam groove 2, the storage box B is automatically moved in the opening direction from the opening of the housing H by the biasing spring pressure.

In the locked state of the storage box B in the closed position, when an inertial force G larger than the spring pressure of the balancing compression spring 8 acts at the time of a vehicle collision or sudden braking, the inertial response is increased. The cam member 1, which also serves as a body, moves in the closing direction of the storage box B against the spring pressure of the compression spring 8 for balancing due to its own weight and the guiding action of the elongated hole-like fitting hole 3. However, at this time, as shown in FIGS. 6 and 7, the storage box B itself also moves together with the cam member 1 in synchronization with the closing direction, whereby the pin member P locks the cam groove 2. It never goes off of section 4c. Therefore, as a result, the cam member 1 is prevented from swinging in the unlocking direction, and the storage box B remains in the closed position in the housing H, and there is no fear of accidentally protruding outward from the housing H. It is a translation. When the inertial force G disappears, the cam member 1 also serving as the inertial actuator moves to the original position by the spring pressure of the balance compression spring 8, and at the same time, the storage box B also returns to the original position by its own biasing spring pressure. As a result of moving to the position and automatically elastically returning to the state of FIGS. 2 and 3, the pin member P does not come off from the lock portion 4c of the cam groove 2 of the cam member 1 in this case as well. Again, the cam member 1 is prevented from turning in the unlocking direction, and the storage box B remains in the closed position in the housing H.

The above embodiment is directed to the storage box B that opens and closes linearly with respect to the housing H, but the present invention is not limited to this, and the storage box B can be rotated downward. It goes without saying that a vertically rotating storage box that is opened by moving and closed by rotating upward can be easily implemented and applied without departing from the spirit of the present invention.

[0016]

[Effect of the device]

 As described above, according to the present invention, the cam member itself, which cooperates with the pin member to lock and unlock the storage box, is also used as an inertial responder, and the cam member is constantly operated only by the spring pressure of the balancing spring. Since it is characterized by urging the storage box in the opening direction, the number of parts required to exert the safety function can be greatly reduced compared to the conventional storage device. Not only can it contribute greatly to simplification and miniaturization, but it can also reduce the man-hours for assembling, which can contribute to the cost reduction. Also, when the inertial force is applied, the cam member that also serves as the inertial responder moves together with the storage box.For example, even when the lock release stroke of the storage box is short, the pin member remains locked to the lock part. Since it will be reliably maintained, its reliability can be greatly improved compared to the conventional one.
