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]

 The applicant has already provided, as a storage device with this type of safety function, that disclosed in Japanese Patent Application No. 3-101344. Although not specifically shown, the storage device supports the 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 in the opening direction via the biasing spring pressure. On the other hand, a cam member having a cam groove is rotatably provided on the housing side, and a pin member that moves within the cam groove of the cam member is provided on the storage box side. When locked in the lock part, the storage box can be locked in the closed position inside the housing against the biasing pressure. If the storage box is pushed further into the housing in this state, the cam groove of the pin member Assuming that the storage box can be automatically moved from the opening of the housing in the opening direction by releasing the lock to the lock part of the Power that doubles as a responder While supporting the member so that it can move in the opening and closing direction of the storage box with respect to the housing, this cam member is always biased by the spring pressure of the balancing spring in the opening direction of the storage box, and only when inertial force is applied. The cam member can be moved together with the storage box in the closing direction of the storage box.

Therefore, in this storage device with a safety function, when an inertial force larger than the spring pressure of the balancing spring acts at the time of a vehicle collision or sudden braking, the cam member also serves as an inertial responder. Will move in the closing direction of the storage box against the spring pressure of the balancing spring, but at this time, the storage box itself will also move in the closing direction together with the cam member, and the pin member will move. As the cam member is reliably prevented from coming off the lock part, as a result, the cam member cannot pivot in the unlocking direction, and the storage box remains in the closed position inside the housing, Accidental protrusion to the outside is prevented. Therefore, even if the opening operation direction for unlocking the storage box at the closed position and the direction of the inertial force generated at the time of collision are the same, the operation of the safety function causes the storage box to be Since it does not project outward from the opening of the housing, there is no need to worry about injuring the driver or passengers.

[0004]

[Problems to be solved by the device]

 However, this storage device, which the applicant has already provided, uses the cam member also as an inertial responder, so the number of parts required to exert a safety function is higher than that of the conventional devices. Since it can be reduced, it has an advantage that it can greatly contribute to the simplification and downsizing of the storage device itself, but on the contrary, due to the fact that the cam member is also used as the inertia response body, the following new problems are caused. To be invited.

That is, the inertial force generated at the time of a collision of a vehicle is not always the same as the opening operation direction for unlocking the storage box at the closed position, and sometimes crosses the direction. It is quite possible that an inertial force from the lateral direction, etc. will act.Therefore, if the storage device receives an inertial force from the lateral direction, this inertial force will cause the inertial response to occur. The cam member that also serves as the body easily pivots in the unlocking direction due to its own weight, and the pin member is easily disengaged from the lock portion of the cam member. Therefore, in this storage device, when an inertial force is applied from the lateral direction or the like, the safety function at the corner cannot be sufficiently exerted.

[0006]

[Means for Solving the Problems]

 The present invention was developed in order to effectively solve the above-mentioned problems of the storage device with a safety function, and the cam member can be rotated to a separately molded inertial reaction body on the technical premise of the basic structure of the device. While supporting the cam member and the inertial responsive body with respect to the housing so as to be movable in the opening / closing direction of the storage box, the movement of the inertial responsive body is guided by a guide wall provided on the housing side of the storage box. A structure is adopted in which only the opening / closing direction is restricted, and the inertia actuator and the cam member are constantly urged in the opening direction of the storage box by the spring pressure of the balancing spring.

[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 locked state of the storage box in the closed position, when the inertial force in the same direction as the opening operation direction of the storage box acts at the time of collision of the vehicle, sudden break, or the like, the balance is applied. First, the inertia response body moves in the closing direction of the storage box by receiving the guide of the guide wall against the spring pressure of the application spring, but at this time, the cam member connected to the inertia response body is also stored. It moves together with the box in the closing direction to reliably prevent the pin member from coming off the lock part of the cam member, and as a result, the cam member cannot pivot in the unlocking direction. The storage box stays in the closed position inside the housing, eliminating the risk of accidentally protruding outward from within the housing.

Further, when an inertial force from a lateral direction or the like intersecting the opening operation direction acts, even if the inertial responder tries to move in the same direction, the inertial responder does not move the guide wall. The movement of the cam in that direction is reliably prevented, and since the weight required for the inertial actuator is not given to the cam member at all, it is as if it was a dual-purpose cam member of the previously provided device. The cam member pivots easily in the unlocking direction, and the pin member is reliably prevented from easily disengaging from the lock portion of the cam member. Therefore, in the present invention, it is possible to prevent the storage box from accidentally protruding outward from the opening of the housing regardless of the inertial force from any direction.

[0010]

【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 the device previously provided by the applicant. , A housing provided on the instrument panel side so as to support the storage box so that it can be opened and closed, and constantly biases the storage box in the opening direction via biasing spring pressure, while a cam member having a cam groove on the housing side 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 side of the storage box, and the pin member is locked to the lock portion of the cam groove of the cam member, the storage box is opened. It can be locked at 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 lock of the cam groove of the pin member with respect to the lock part is released, Allows turning in the unlocking direction of the cam member By assumes a configuration which can be moved automatically to the opening direction from the opening of the housing by the biasing spring pressure receiving box.

However, in the present embodiment, unlike the above-mentioned device, the cam member itself is not positively given the weight necessary as the inertial responsive body so that the cam member itself also serves as the inertial responsive body. As shown in FIG. 1, the cam member 1 and the inertial responding body 2 are separately molded, and the cam member 1 and the inertial responding body 2 are rotatably coupled to each other, and the both 1 and 2 are coupled. It was developed with a focus on keeping it running.

Explaining this concretely, the cam member 1 is a lightweight body integrally molded of synthetic resin, and as shown in the drawing, a cam groove 3 for guiding the movement of the pin member P provided on the storage box B side. In addition to the above, a fitting hole 4 into which a mounting shaft portion 8 provided on the housing H side is fitted is formed in a proper shape near the rear end portion in a long hole shape, and the mounting shaft portion 8 has a washer 9 and a torsion spring. At the same time, it is rotatably supported via 10, and is also supported so as to be movable in the opening / closing direction of the storage box B with respect to the housing H by utilizing the elongated hole shape of the fitting hole 4. .. The torsion spring 10 has a function of constantly urging the cam member 1 in a predetermined direction by its spring pressure until the cam wall 1 is regulated by the stopper wall portion 11. Both end portions of the torsion spring 10 have arm portions 1a of the cam member 1. And the locking wall portion 12 on the housing H side. In addition to this, in this embodiment, a connecting shaft portion 5 that fits into a connecting hole portion of the inertial response body 2 described later is formed at the rear end portion of the cam member 1 and is connected to the connecting shaft portion 5. The rear end of the cam member 1 is rotatably connected to the inertial responding body 2 by fitting the hole.

On the other hand, the inertial response body 2 is formed in a rectangular shape from a heavy metal material or the like, and a pair of U-shaped guide walls 13 provided on the housing H side allow the inertial response body 2 to move in the opening / closing direction of the storage box B. Is formed so as to be movable only, and an arcuate connecting hole portion 7 is formed on the bottom surface side thereof to rotatably fit the connecting shaft portion 5, and the rear end portion of itself and the housing H are associated with each other. A balancing compression spring 14 is provided between the side wall surfaces, and is constantly elastically biased in the opening direction of the storage box B by the spring pressure of the balancing compression spring 14. Therefore, the urging state of the inertial response body 2 is transmitted to the cam member 1 as it is, and the cam member 1 is always urged in the opening direction of the storage box B.

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 in the housing box B because the balance compression spring 14 has a higher spring pressure. If the pin member P provided on the rear end side of the storage box B is brought into contact with the first guide portion 6a of the cam member 1 when pushed into the housing H against the biasing spring pressure, the cam member 1 1 reaches the inlet of the cam groove 3 while turning 1 against the spring pressure of the torsion spring 10 and comes into contact with the second guide portion 6b of the cam member 1, this time, the cam member 1 moves to the above-mentioned position of the torsion spring 10. Since the spring member pivots slightly in the biasing direction, the pin member P is introduced into the cam groove 3, but at this time, the storage box B also retracts due to the biasing spring pressure. As shown in FIGS. 2 and 3, the pin member P is It automatically engages with the lock portion 6c of the groove 3 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 6c of the cam groove 3 and the cam member 1 is further biased (lock unlocking direction). 4), the pin member P is guided by the inclined third guide portion 6d as shown in FIGS. 4 and 5, and the cam member 1 is rotated. Since it is automatically disengaged from the cam groove 3, the storage box B is automatically moved in the opening direction from the opening of the housing H by the biasing spring pressure. When the storage box B is opened and closed, even if the cam member 1 is connected to the inertia response body 2, the connection shaft portion 5 is rotatably fitted in the connection hole portion 7 of the inertia response body 2. Due to the combined relationship, there is no concern that the turning movement of the cam member 1 will be hindered.

In the locked state of the storage box B at the closed position, the spring pressure of the balance compression spring 14 is greater than the spring pressure of the balance compression spring 14 at the time of a vehicle collision or sudden braking, and the operation of opening the storage box B is performed. When the inertial force G1 in the same direction as the direction acts, the inertial response body 2 first obtains its own weight and the guide of the guide wall 13 against the spring pressure of the balance compression spring 14. , The storage box B is moved in the closing direction, but at this time, as shown in FIGS. 6 and 7, the cam member 1 connected to the inertia response body 2 also guides the elongated hole-like insertion hole 4. As a result of the action, the pin member P moves together with the storage box B in the closing direction of the storage box B, so that the pin member P is never disengaged from the lock portion 6c of the cam groove 3. 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. ..

When the inertial force G1 disappears, the inertial responsive body 2 moves to the original position with the cam member 1 by the spring pressure of the balance compression spring 14, and at the same time, the storage box B also urges itself. As a result of moving to the original position by the spring pressure and automatically returning to the state shown in FIGS. 2 and 3, the pin member P also disengages from the lock portion 6c of the cam groove 3 of the cam member 1 in this case as well. Therefore, the cam member 1 is prevented from pivoting in the unlocking direction, and the storage box B remains in the closed position in the housing H.

Further, when the lateral inertial force G2 intersecting the direction of the inertial force G1 acts in the locked state of the storage box B shown in FIGS. Even if the inertial response body 2 tries to move in the same direction, the inertial response body 2 is surely prevented from moving in that direction due to the existence of the guide wall 13, and the cam member 1 has the inertial response body 2. Since the necessary weight is not given at all, the cam member 1 easily pivots in the unlocking direction, like the dual-purpose cam member of the previous device, and the pin member P moves from the lock portion 6c of the cam member 1. It is reliably prevented from coming off easily. Therefore, in the storage device of the present embodiment, the storage box B may accidentally project outward from the opening of the housing H regardless of the inertial forces G1 and G2 from any direction. It can be prevented.

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. Needless to say, the present invention can be easily applied to a vertically rotatable storage box that is opened by opening and closed by rotating upward, as long as it does not violate the spirit of the present invention.

[Effect of the device]

 As described above, according to the present invention, the cam member and the inertial response body are separately formed, and the latter inertial response body is supported by the guide wall that restricts the moving direction of the latter. It is characterized in that the member and the member are constantly urged in the opening direction of the storage box by the spring pressure of the balance spring, so of course when an inertial force in the same direction as the opening operation direction of the storage box acts. Therefore, even if an inertial force from a lateral direction that intersects with this direction is applied, its safety function is fully exerted, and it is possible to completely prevent the storage box from accidentally protruding outward from the housing. It can be prevented.
