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. However, the storage box 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, and the pin member moves. As the cam member is reliably prevented from coming off the lock part, as a result, the cam member cannot turn in the unlocking direction, the storage box remains in the closed position inside the housing, and It is prevented from accidentally projecting in one direction. 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 improve the storage device with the above-mentioned safety function, and the weight of the cam member is added to the cam member as an inertial response body so that the inertial response body can also be used. While supporting the cam member of the housing so that it can move in the opening and closing direction of the storage box with respect to the housing, the cam member is constantly urged in the opening direction of the storage box by the spring pressure of the balancing spring. Adopts a configuration in which the center of gravity of the cam member and the center of rotation of the cam member coincide.

[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. The cam member, which also serves as the inertial responding body, moves in the closing direction of the storage box against the spring pressure of the application spring, and at the same time, the storage box itself moves in the closing direction together with the cam member, and the pin member moves. As the cam member is reliably prevented from coming off the lock part, as a result, the cam member cannot turn in the unlocking direction, the storage box stays in the closed position in the housing, and is not removed from the housing. There is no worry of accidentally protruding.

Further, when an inertial force is applied from a lateral direction or the like which intersects the opening operation direction, even if the cam member is provided with a weight necessary as an inertial response body, the closed position of the storage box is maintained. In the locked state, that is, in the state of being urged in the opening direction of the storage box by the spring pressure of the balancing spring, the center of gravity of the cam member and the turning center of the cam member coincide with each other. Like the dual-purpose cam member, the cam member is easily swung in the unlocking direction by the inertial force from the lateral direction or the like, and the pin member is reliably prevented from coming off 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, the present embodiment is not limited to simply providing the above-mentioned cam member itself with the weight necessary as the inertial responsive body as in the above-described device, and in the locked state of the storage box in the closed position. It is characterized by further adding a configuration in which the center of gravity of the cam member that also serves as the inertial responding body and the center of rotation thereof are made to coincide with each other. As a method of giving a necessary weight to the cam member, for example, the cam member itself is integrally molded with a heavy metal material, or the cam member is molded with a synthetic resin material and the resin is A method in which a separately formed weight body is assembled to the cam member by a known fixing means is conceivable. In the illustrated embodiment, the latter method is adopted. However, the present invention is not limited to this.

Explaining this concretely, the cam member 1 which also serves as an inertial responding body also has a cam groove 2 for moving and guiding the pin member P provided on the storage box B side, as shown in FIG. The mounting shaft portion 7 on the housing H side is rotatably supported by a washer 8 and a torsion spring 9, and is constantly urged in a predetermined direction by the spring pressure of the torsion spring 9. In this case, the fitting hole 3 into which the mounting shaft portion 7 is fitted is formed in a long hole shape on the rear end side of the cam member 1, and the long hole shape of the fitting hole 3 is used to make the cam member 1 While supporting the housing H so as to be movable in the opening / closing direction of the storage box B, and integrally forming a plurality of holding claws 4 for holding the weight body 6 around the elongated hole-like fitting hole 3. Then, the U-shaped weight body 6 is attached to the cam member 1 by each holding claw 4. It is said to be composed.

Also, in the present embodiment, in addition to this, a balance compression spring 10 is provided between the rear end portion of the cam member 1 and the corresponding side wall surface of the housing H, and the balance compression spring 10 is provided. Although the cam member 1 is always elastically biased in the opening direction of the storage box B by the spring pressure of the spring 10, the difference from the previous device is that in the biasing state in this opening direction. The center of gravity of the cam member 1 which also serves as the inertial responding body and the center of the mounting shaft portion 7, in other words, the center of rotation thereof, coincide with each other. In the figure, 11 is a stopper wall portion that regulates the turning biasing position of the cam member 1, and 12 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 9. Is.

Therefore, even in the case of the storage device having such a structure, 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 10 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 5a of the cam member 1 by pushing it into the housing H against the biasing spring pressure, the cam When the member 1 reaches the introduction port of the cam groove 2 while rotating against the spring pressure of the torsion spring 9 and comes into contact with the second guide portion 5b of the cam member 1, the cam member 1 is turned to the above-mentioned torsion spring. Since the spring member 9 pivots slightly in the biasing direction, the pin member P is thereby introduced into the cam groove 2, but at this time, the storage box B also retracts due to the biasing spring pressure. Finally, as shown in FIG. 2 and FIG. It automatically engages with the lock portion 5c of the 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 5c of the cam groove 2, and the cam member 1 is further biased in the unlocking direction (lock releasing direction). 4), the pin member P is guided by the inclined third guide portion 5d 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, the spring pressure of the compression spring 10 for balancing is greater than the spring pressure of the balance compression spring 10 and the opening operation of the storage box B is performed when the vehicle collides or is suddenly braked. When an inertial force G1 in the same direction as the direction acts, the cam member 1 which also serves as an inertial responding body also has its own weight and the guiding action of the elongated hole 3 to cause the spring of the balance compression spring 10 to move. Although it moves in the closing direction of the storage box B against the pressure, at this time, as shown in FIGS. 6 and 7, the storage box B itself is synchronized with the cam member 1 in the closing direction. As a result, the pin member P is never disengaged from the lock portion 5c of the cam groove 2. 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 cam member 1 also serving as the inertial responder moves to its original position by the spring pressure of the balance compression spring 10, and at the same time, the storage box B is urged by itself. As a result of moving to the original position by spring pressure and automatically elastically returning to the state of FIGS. 2 and 3, the pin member P also disengages from the lock portion 5c of the cam groove 2 of the cam member 1 in this case as well. Since the cam member 1 is prevented from swinging in the unlocking direction, the storage box B remains in the closed position in the housing H.

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. 2 and 3 in the closed position, for example, the cam portion Even if the material 1 is given a weight necessary for the inertial responding body, in this state, the cam member 1 is biased in the opening direction of the storage box B by the spring pressure of the balance compression spring 10 and self-actuates. Since the center of gravity of the cam is coincident with the center of rotation of the pin, the cam member 1 easily pivots in the unlocking direction by the lateral inertial force G2, like the dual-purpose cam member of the previously provided device, and the pin is rotated. The member P is also reliably prevented from easily disengaging from the lock portion 5c of the cam member 1. 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. Further, in the embodiment, the independent compression spring 10 is used as the balancing means for constantly urging the cam member 1 in the opening direction of the storage box B, but the compression spring 10 is omitted. The torsion spring 9 can also be used as a means for urging the storage box B in the opening direction.

[0020]

[Effect of the device]

 As described above, the present invention is based on the premise that the cam member itself, which cooperates with the pin member to lock and unlock the storage box, is also used as the inertial responder, like the device previously submitted. However, since it is characterized in that the center of gravity of the cam member and the turning center of the cam member are made to coincide with each other when the balance spring is biased in the opening direction of the storage box by the spring pressure. Not only when an inertial force is applied in the same direction as the opening operation direction of the storage box, but also when an inertial force is applied from a lateral direction that intersects this direction, its safety function is fully exerted. As a result, it is possible to completely prevent the storage box from accidentally protruding outward from the housing.
