Description

[Detailed Description of the Invention] The present invention relates to a double locking device in which a movable member is locked to a fixed member by two locking devices. The present invention relates to a double locking device in which these members are fixed to each other by locking the locking device and then operating the other locking device.

For example, in a high-roof type automobile, it is conceivable to use the space under the roof to provide a large console box on the rear roof portion of the vehicle interior. In that case, the console box main body is fixed to the lower surface of the roof on the vehicle body side, and can be opened and closed using a lid. This lid body is
The box is supported on a box body so as to be able to rotate vertically, and the box is opened by rotating downward.

In such a device, the lid is locked to the box body by a locking device, but there is no possibility that the lock may come off due to vibrations while driving, and the lid may fall under its own weight. If there is a problem, the rear view may be obstructed by the lid or the rear seat occupant may feel uncomfortable. Therefore, it is desirable that such a lid be reliably locked to the box body by a double locking device using two locking devices.

By the way, such a double locking device generally temporarily locks a movable member such as a lid and a fixed member such as a box body by one locking device.
The other locking device is then operated to secure these parts together. and,
One of the temporary locking devices has a claw that protrudes to the side by spring force, and has a simple structure in which the claw locks the other member by engaging with it. It is said to belong to Such a locking device cannot be unlocked unless the operating member is operated to retract the pawl. When the operating member is released, the claws protrude and return to the engaged state. Therefore, in a console box or the like using such a double locking device, if the two locking devices are released in the wrong order, the lid, etc. cannot be opened.

In addition, in such a double lock device,
Each lock device has its own operating member, but if a large number of operating members are exposed,
Not only is this not visually appealing, but it also becomes difficult to identify which lock device is being operated, and is likely to cause erroneous operation.

The present invention was devised in view of the above circumstances, and its purpose is to provide a double lock device that completely prevents erroneous operations and is simple in appearance.

Another object of the present invention is to make it possible to identify at a glance that two locking devices are both locked, thereby reliably preventing forgetting to lock them.

In order to achieve these objectives, this invention:
A first operating member for operating the first locking device and a second operating member for operating the first locking device.
A second operating member for operating the second locking device is provided adjacent to the second operating member, and a cover body is provided which is rotated by operating the second operating member, and when the second locking device is locked, the cover body is provided. 1st by body
The operating member is covered so that the first operating member is exposed when the second locking device is unlocked.

On the other hand, the cover body 16 is provided with a protrusion 16a that tightly engages with the engagement groove 17a when the cover body 16 is in a position to completely cover the recess R. When these protrusions 16a and the engagement grooves 17a engage,
When the surface of the cover body 16 is flush with the lower surface 2a of the lid body 2 and the protrusion 16a is out of the engagement groove 17a, the surface of the cover body 16 is flush with the lower surface 2a of the lid body 2.
It protrudes downward from.

At the upper end of the lock plug 12, wing portions 12b are provided that extend to both sides. On the other hand, a circular through hole 18 is provided in the lock receiving portion 7 on the side of the box body 1, and a striker 19 is fixed to the upper surface of the through hole 18. This striker 19 has a wing portion 1 of the lock plug 12.
2b, and a tapered surface 19b that can be engaged with the wing portion 12b.
is formed. This tapered surface 19b is formed in the circumferential direction on both sides of the insertion hole 19a,
When the wing portion 12b of the lock plug 12 inserted through the insertion hole 19a is rotated, the wing portion 12b is pulled up along the tapered surface 19b.

Next, the double lock device L configured in this way
The effect of this will be explained.

Now, as shown in FIG. 2, the lid 2 is attached to the hinge shaft 3.
Assume that the console box C is opened by being rotated downward around the console. At this time, the second lock device 10 is in the unlocked position, and the cover body 16 is in a position where its longitudinal direction is approximately perpendicular to the longitudinal direction of the opening of the recess R, as shown in FIG. , the first operating member 8 of the first locking device 8
A is exposed. In this state, the cover body 1
The protrusion 16a of 6 is disengaged from the engagement groove 17a of the guide surface 17 on the lid body 2 side, and the protrusion 16a and the flat part of the guide surface 17 are in contact with each other, so that the guide surface 17 and the cover body 16 are The distance corresponds to the height of 16a. Thereby, the surface of the cover body 16 protrudes downward from the lower surface 2a of the lid body 2, and is held so as to be rotatable along the lower surface 2a of the lid body 2.

When closing the console box C from this state, the lid 2 is lifted and rotated around the hinge shaft 3, and the lid 2 is pressed toward the box body 1. Thereby, as mentioned above, the first
The lock body 8b of the locking device 8 is inserted into the locking hole 9 of the lock receiving part 7 on the box body 1 side, and its claw 8d engages with the lock receiving part 7, and the lid body 2 is temporarily attached to the box body 1. be stopped. Note that even if the claw 8d of the first locking device 8 is inserted or removed only by operating the operating member 8a, the operating member 8a is exposed in this state as described above. Through this operation, they can be temporarily fixed in the same way.

In this manner, when the lid body 2 is temporarily attached to the box body 1, on the side of the second lock device 10, the wing portion 12b of the lock plug 12 is inserted into the insertion hole of the striker 19, as shown in FIG. 1
9a. Therefore, when the second operating member 13 of the second locking device 10 is rotated in this state, the second operating member 13
The spacer 11, whose relative rotation is restrained, and the lock plug 12 fixed to the spacer 11 rotate together, and the wing portion 12b of the lock plug 12 rides on the tapered surface 19b of the striker 19, which gradually becomes higher. As a result, the lock plug 12, the spacer 11, and the bottom wall 5 held between the lock plug 12 and the spacer 11 are drawn toward the lock receiving portion 7 of the box body 1. Due to this action, even when the first locking device 8 is in a half-locked state, the claw 8
d passes through the locking hole 9, and the locking device 8 is completely locked. As the second operating member 13 rotates, the cover body 16 also rotates in the same direction, but during this period, the protrusion 16a of the cover body 16 slides along the flat part of the guide surface 17, and the cover body 16 also rotates in the same direction. It is held in a floating state from the lower surface 2a of the lid body 2.

From the state shown in FIG.
When the operating member 13 is rotated 90 degrees counterclockwise, the wing portion 12b of the lock plug 12 comes to engage with the tapered surface 19b of the striker 19 at its highest position, and the lid is closed as shown in FIG. The bottom surface 5 of the recess R of the box body 2 and the lock receiving portion 7 of the box body 1 are fixed to each other. At this time, the cover body 16 also rotates 90 degrees counterclockwise in FIG. 3, so that it completely covers the recess R of the lid body 2, as shown in FIG. In this state, the cover body 16
The position of the protrusion 16a and the engagement groove 17a of the guide surface 17
Since the positions of the two lines tend to match, they engage with each other. Therefore, the second operation member 13 that is urged toward the spacer 11 by the compression spring 14 and the cover body 1 fixed thereto
6 is drawn toward the opening side of the recess R, and the cover body 16 fits into this opening to completely close the recess R, and the surface of the cover body 16 and the lid body 2
The lower surface 2a of the holder is now flush with the lower surface 2a of the holder.

In this way, when the first locking device 8 and the second locking device 10 are completely locked, the recess R of the lid body 2 is completely closed by the cover body 16, so that the locking mechanism 8 and the second locking device 10 are completely locked. The condition can be judged at a glance. Moreover, since the cover body 16 is flush with the lower surface 2a of the lid body 2,
Objects do not get caught and the appearance is very good.

When removing the lid body 2 locked by the double locking device L from the box body 1 and opening the console box C, first, the second operating member 13 of the second locking device 10 is opened as shown in FIG. Rotate 90 degrees clockwise. During this time,
The protrusion 16a of the cover body 16 is disengaged from the engagement groove 17a of the guide surface 17, and the cover body 16 is attached to the lower surface 2 of the lid body 2.
Since the cover body 16 protrudes downward from a, the cover body 16 can rotate as the second operating member 13 rotates. Then, when the second operating member 13 rotates 90 degrees, the cover body 16 also comes to form an angle of 90 degrees with respect to the longitudinal direction of the recess R as shown in FIG. The operating member 8a is exposed. At this time, as shown in FIG. 4, the wing portion 12b of the lock plug 12 is rotated to the position of the insertion hole 19a of the striker 19, and the engagement between the lock plug 12 and the striker 19 is completely disengaged. Then, the first operating member 8a of the first locking device 8 is operated to retract the claw 8d. If the lid body 2 is pulled down in this state, the lock body 8b of the first lock device 8 will be pulled out from the locking hole 9 of the lock receiver 7, and the second lock device 10 will be removed.
The lock plug 12 also has the insertion hole 1 of the striker 19.
9a, the lid body 2 is rotated downward around the hinge shaft 3, and the console box C is opened.

In this way, when releasing the lock by this double locking device, first the second locking device 10 is released.
The first locking device 8 cannot be unlocked unless the second operating member 13 of the lock device is unlocked and the cover body 16 is rotated, so do not make a mistake in the order of operations. do not have.

In the illustrated embodiment, the pin 1 fixed to the second operating member 13 of the second locking device 10 is
5 and the through hole through which it passes through the spacer 11, a slight gap is provided so that the pin 15 can be inclined with respect to the spacer 11.
Furthermore, the protrusion 13a of the second operating member 13 and the recess 11b of the spacer 11 are fitted with some play. By doing so, this double lock device can be provided even when the rotational axis of the second operating member 13 and the rotational axis of the spacer 11 do not coincide. Therefore, even if the box body 1 and the lid 2 are not parallel, the cover 16 can be made flush with the surface of the lid 2 in the locked position.

In the above embodiment, a double lock device installed in a console box C of an automobile M is shown, but such a double lock device can also be used as a lock device for other rotating members. That should be obvious. For example, in a high-roof type hatchback vehicle, a rotatable speaker box is provided on the lower surface of the roof of the interior of the vehicle so that the speaker box can face the inside of the vehicle or face the rear outside the vehicle. In order to be able to hold the speaker box fixedly in place, it is conceivable to use such a double locking device.

As the first lock device 8, various general-purpose devices can be used in addition to those shown in the above embodiments. For example, the hook may be rotated by operating the first operating member 8a to be engaged with and disengaged from the lock receiving portion 7.

As is clear from the above description, according to the present invention, the first operating member of the first locking device rotates the cover body by operating the second operating member of the second locking device. The first locking device cannot be operated unless the second locking device is in the specified state, and therefore there is no possibility of mistaking the order of its operation. Nothing will happen. Since the first operating member of the first locking device is exposed unless the second locking device is locked, it can be determined at a glance whether or not the second locking device is locked. This will surely prevent you from forgetting to lock your device.
Further, when the second locking device is locked, the first operating member of the first locking device is covered by the cover body, so that the appearance when the second locking device is locked is extremely simple. Can be done.

Moreover, since the movable member and the fixed member are independently locked by both the first locking device and the second locking device, they are doubly locked, and the locking between them is reliable. Become something. Further, since the cover body is integrally formed with the second operating member, the cover body is rotated simultaneously with the locking or unlocking operation of the second locking device. Therefore, there is no need to operate the cover body separately.
