[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention can be applied to, for example, moving an openable / closable body provided on the dashboard side of an automobile in the closing direction so as to secure a closed lock state of the open / close body. The present invention relates to an improvement in a vehicle lock device that can automatically release the above-mentioned closed lock state when the opening / closing body is further moved in the closing direction and move the opening / closing body in the opening direction.

2. Description of the Related Art As a conventional lock device of this kind, there are lock devices disclosed in Japanese Utility Model Laid-Open No. 60-184963 and Japanese Utility Model Laid-Open No. 62-67071. The conventional locking device,
Although not specifically shown, a slider is movably mounted inside a cylindrical case fixed to the dashboard side or the like, and the slider is constantly urged outward from the cylindrical case by urging spring pressure. At the same time, a cam means is provided on one of the cylindrical case or the slider, and a swing pin member is provided on the other, which is engaged with and disengaged from the cam means. When pressed inward of the case, the rocking pin member is locked by the cam means to restrain the slider at its inward position, whereby the closed lock state of the opening / closing body can be ensured. When the slider in the restrained position is further pressed inward by the movement of the body, the locking of the swing pin member to the cam means is released, and the slider is automatically moved outward by the urging spring pressure. To open and close the opening and closing body. State and has a configuration that can be guaranteed. Therefore, in such a lock device, it is possible to easily obtain the closed lock state and the open state only by moving the opening / closing body in the same direction and pressing the slider inward. It can be said that it is extremely convenient as a lock device for various opening / closing bodies including it.

[0003]

However, when a large inertial force acts upon a collision or sudden braking of an automobile in a state where the opening / closing body is locked in the closed position under the conventional locking device, Since the direction of the inertial force is the same as the direction in which the slider at the restrained position is released from the restraint, once the inertial force acts in such a state, the opening / closing body moves in the same direction due to the inertial force. By moving the slider inward of the cylindrical case, the locking of the swing pin member with respect to the cam means is easily released.
There was a risk that the opening and closing body would be accidentally opened. Therefore, there is a great demand in the art for a lock device with a safety function that can prevent a driver or a passenger from being harmed by erroneous opening of the opening / closing body due to the inertial force.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed in response to such a demand, and a slider is movably mounted in a cylindrical case having an open front end, and the slider is biased. The spring is always urged outward from the cylindrical case, and a cam means is provided on one of the cylindrical case or the slider, and a swing pin member is provided on the other of the cam means to move the opening / closing body. Then, when the slider is pressed inward of the cylindrical case against the urging spring pressure, the swing pin member is locked by the cam means, and the slider is restrained at the inward position. When the closing / locking state of the body is ensured, and the slider at the restrained position is further pushed inward by the movement of the opening / closing body, the locking of the swing pin member to the cam means is released, and the slider is moved by the urging spring. Automatically move outward by pressure Further, on the premise of a vehicle opening / closing body locking device that guarantees the open state of the opening / closing body, a safety member that prevents the slider in the restrained position from moving inward is turned around the rear end of the cylindrical case. The safety member is configured to be movably provided, and only when an inertial force is applied, the inertia-responsive sphere is moved to rotate the safety member in a direction that prevents the slider from moving inward.

[0005]

Therefore, according to the present invention, if the opening / closing body is moved in the closing direction and the slider mounted in the cylindrical case is pressed inward, the swing pin is interlocked therewith. Since the member is locked to the cam means and restrains the slider at the inner position thereof against the urging spring pressure, the closing lock state of the opening / closing body is ensured, and the opening / closing body is kept closed in the closing direction. When the slider at the restrained position is further pressed inward, the locking of the swing pin member to the cam means is released, and the slider is automatically moved outward by the biasing spring pressure. Therefore, the open state of the opening / closing body is thereby ensured.

However, when a large inertial force is applied in a closed or locked state of the opening / closing body at the time of a collision or sudden braking of an automobile, the inertial responsive sphere moves to cause a rear end side of the cylindrical case to move. The forcible rotation of the safety member provided at the lock position prevents the slider in the restrained position from further moving inward, so that the slider moves inward as in the related art. The locking of the moving pin member to the cam means is easily released, and the opening / closing body can be completely prevented from being accidentally opened.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.
As shown in the figure, a rectangular slider 2 is movably mounted inside a cylindrical case 1 having an open front end 1a side, and a stopper 2a of the slider 2 is attached to an edge of the guide groove 3 of the cylindrical case 1. Until contact, the outer end 2 of the slider 2
b is always urged outward by the spring pressure of the compression coil spring 4, and a cam means 5 having a lock portion 5 a is integrally provided on the bottom wall surface of the cylindrical case 1, while a corresponding portion of the slider 2 is provided. Further, a swing pin member 6 which is elastically urged in a predetermined direction by the spring pressure of the compression coil spring 4 is provided so as to be swingable. Therefore, when the slider 2 is pressed inward of the cylindrical case 1 against the urging spring pressure of the compression coil spring 4 by movement of the opening / closing lid described later, the swing pin member 6 locks the cam means 5. The slider 2 can be restrained at its inward position by being locked to the portion 5a. In this state, when the slider 2 is further pressed slightly inward, the swing pin member 6 is engaged with the lock portion 5a. The stop is released, and the slider 2 can be automatically moved outward by the urging spring pressure. Although the cam means 5 is not shown in detail, it goes without saying that a guide portion for introducing and ejecting the swing pin member 6 is integrally provided in its own lock portion 5a.

In the present embodiment, in addition to this, as shown in FIG.
A mounting wall 8 having a concave surface 8a for movably mounting a sphere 7 as an inertial responder between a standby position and an operating position is integrally formed with the stopper wall 9a on both sides of the mounting wall 8. , Which is rotatably supported, and is constantly urged by the spring pressure of the torsion spring 10 in the direction in which the stopper claw 9a rotates upward and outward. By arranging the inertial response sphere 7 movably between the mounting wall 9 and the mounting wall 8, the inertial response sphere 7 is normally attached to the standby position of the mounting wall 8 by the spring pressure of the torsion spring 10. When the inertia force is applied, the inertia-responsive sphere 7 is moved to the operating position to forcibly rotate the safety member 9 in the opposite direction, and the stopper claw 9a of the safety member 9 is moved.
A configuration is adopted in which the window case 11 is formed to penetrate between the rear end wall 1b and the inner end 2c of the slider 2 from the window 11 formed on the upper surface of the cylindrical case 1.

In this embodiment, the slider 2 is provided on the outer end 2b side projecting outward from the front end opening of the cylindrical case 1 with
A pair of stoppers 12a and 1 for detachably holding the opening / closing body
When the slider 2 is moved inward while the free ends of the stoppers 12a and 12b are urged in a direction to expand by a spring 13, the stoppers 12a and 12b are pivoted.
The free ends of 12b are configured to close together.

Therefore, the lock device having such a configuration is now temporarily attached to a rotatable opening / closing lid L provided for opening / closing audio equipment A mounted on a dashboard B of an automobile shown in FIG. If used, Dashboard B
At the side, the cylindrical case 1 of the lock device is
c, and an L-shaped receiving portion 14 is provided on the upper back surface side of the opening / closing lid L. When the opening / closing lid L is rotated in the closing direction, the receiving portion 14 of the opening / closing lid L is moved outside the slider 2. The end portion 2b is pressed inward, and as shown in FIGS.
The slider 2 is securely locked at the inward position by being locked to the lock portion 5a of the cam means 5 provided on the side, while the pair of stoppers 12a and 12b are closed together, and the opening / closing lid L is closed. Since the receiving portion 14 is securely held,
As a result, the opening / closing lid L is placed in the closed lock state.

When the opening / closing lid L is further rotated in the closing direction in this state, as shown in FIGS. 6 and 7, the rocking pin member 6 comes off the lock portion 5a of the cam means 5. The outward movement of the slider 2 is immediately permitted by the swing pin member 6 swinging in a predetermined direction in response to the urging spring pressure. As a result, the slider 2 Until the portion 2a comes into contact with the edge of the guide groove 3, it is automatically pushed out by the spring pressure of the compression coil spring 4, and at the same time, in conjunction with this, a pair of stoppers 1
8a and 12b are expanded by the spring pressure of the spring 13, and the holding of the receiving portion 14 of the opening / closing lid L is released.
As shown in FIG. 9, the opening / closing lid L automatically rotates in the opening direction.

When the inertia force G larger than the spring pressure of the torsion spring 10 is applied during a collision of an automobile, sudden braking, or the like in the closed lock state of the opening / closing lid L, FIG. Like, inertial response sphere 7
Moves from the standby position to the operating position, rotates the safety member 9 in a direction opposite to the biasing direction of the torsion spring 10, and moves the stopper claw 9 a of the safety member 9 from the window 11 to the cylindrical case 1. The slider 2 is instantaneously penetrated between the rear end wall 1b and the inner end 2c of the slider 2, so that the inward movement of the slider 2 at the restrained position is completely prevented. Therefore, in the present embodiment, the swing pin member 6 does not easily come off the lock portion 5a of the cam means 5 by the movement of the slider 2 as in the related art.
That is, the closing / locking state of the opening / closing lid L is reliably maintained, so that accidental opening of the lid L is completely prevented.
When the inertia force G disappears, the safety member 9 rotates again in the biasing direction to move the inertial response sphere 7 to the standby position, and at the same time, the stopper claw 9a of the safety member 9 is moved to the cylindrical case 1.
Since it is pivoted upward from the inside to the outside, the normal opening and closing operation described above is immediately guaranteed.

In the above embodiment, the opening / closing body is the opening / closing lid L pivotally supported on the dashboard B side, but the present invention is not limited to this. However, it is needless to say that the present invention can be applied to an opening / closing lid L configured to be mechanically moved in the opening direction via a forced moving means or a braking means thereof,
In addition to this kind of lid L, a box itself such as a glove box or an ashtray case may be used as the opening / closing body according to the embodiment.

[0014]

As described above, the present invention employs the above-described structure, and the inertia-responsive sphere can be used even when a large inertia force is applied to the vehicle in the event of a collision or sudden braking in the closed lock state of the opening / closing body. Is moved to forcibly rotate the safety member provided on the rear end side of the cylindrical case, so that the slider at the restrained position can be reliably prevented from moving further inward. As described above, the locking of the swing pin member with respect to the cam means due to the movement of the slider can be easily released, and the opening and closing body can be completely prevented from being accidentally opened. In addition, in the present invention, it is possible to provide a safety function to the lock device only by adopting an extremely simple structure in which the safety member is rotated by the inertial response ball, so that the lock device itself can be downsized. Can greatly contribute to
