Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lock structure for a glove box of a vehicle.

(Prior Art) Generally, the glove box lid of a vehicle is
By operating a swingable knob on the lid, a hook that engages with a striker on the glove box side is actuated, and the lid is released by disengaging the two from each other. However, in recent years, devices have been developed that have a lock structure that makes the hook inoperable.
In such a lock structure, if the knob cannot be operated when the hook is inoperable, if the user operates the knob without knowing that it is in the locked state, abnormal force may be applied to the knob. act,
This may lead to damage.

In order to deal with this problem, Utility Model Application No. 58-62753
As mentioned in the issue bulletin, there is already a lock structure with a swinging type knob and a vertically sliding type hook that is configured so that the operating force of the knob does not act on the hook when locking (i.e., in a dry firing state). Proposed. That is, as shown in FIG.
A key cylinder (not shown) connects the connecting rod C that engages or engages with the engagement piece B of the swing type knob A.
When the engaging piece B and the connecting rod C are in a disengaged state ( In other words, when the lock is in place), the operating force of the knob A is not applied to the hook D. However, in the case of this known example, since a vertically sliding type hook D is adopted, it is necessary to take the operating stroke l of the hook D in the vertical direction, and the vertical dimensions of the locking device are inevitably large. When combined with the operation space S, the vertical dimension h that occupies the entire lock device
becomes larger. On the other hand, due to its installation location (instrument panel), glove boxes
Since the lid cannot have a very large dimension in the vertical direction, the vertical dimension of the lid is naturally limited. Therefore, it may be technically difficult to attach a locking device having a large vertical dimension as in the above-mentioned known example to such a lid which has a limited vertical dimension.

(Purpose of the invention) This invention was made in view of the above points.
The purpose of the present invention is to provide a compact lock structure with a small vertical dimension and a swing type knob blank firing structure, which is ideal for installation in the lid of a glove box with limited vertical dimensions. It is something to do.

(Means for Achieving the Object) In the present invention, as a means for achieving the above object, a horizontal sliding type hook provided on the lid of the glove box to engage with a striker provided on the glove box main body is provided. A key cylinder is formed with a sloping part that acts as a cam surface for slidingly operating the hook, and a contact part that comes into contact with the sloping part at one end is formed on a key cylinder that prevents the lid from opening when the lid is locked. a swing-type knob that connects a connecting rod consisting of the striker and is provided on the lid and that slides the hook to release the engagement with the striker;
An engaging piece is formed that applies a rotational movement to the inclined part via the abutting part, and when the key cylinder is unlocked and locked, the abutting part is rotated by the engaging piece. It is possible to move within the locus and outside the rotation locus.

(Function) In the present invention, the following effects can be obtained by the above-mentioned means.

(1) When the key cylinder is unlocked, as the knob swings, the rotational movement of the engagement piece is applied to the inclined part of the hook via the contact part of the connecting rod, and the rotational force causes the hook to slide horizontally. and the engagement with the striker is released.

(2) When the key cylinder is locked, the abutment part of the connecting rod is located outside the rotational trajectory of the engagement piece;
This results in a blank firing state in which the rotational movement of the engaging piece cannot act on the inclined portion of the hook.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The lock structure of the present invention is for holding a lid 3 of a glove box 2 provided in an instrument panel 1 in a closed state at the front of an automobile body (see FIG. 4).

The lid 3 can be opened and closed by hinge-coupling its lower end to the opening edge of the glove box 2, and a locking device 5, which will be described in detail later, is attached to a recess 4 formed in the upper part of the lid 3. There is.

This locking device 5 is fixed in the recess 4,
It has a lock body 9 that horizontally slides and holds a hook 8 that engages with a striker 7 provided on the side of the glove box body 6. The lock body 9 includes a holding portion 10 having a U-shaped cross section that holds the hook 8 in a horizontally slidable manner, and a pair of bearing pieces that protrude from the front surface of the lock body 9 and pivotally support a swing type knob 11. 12, 12, and a key cylinder 13 integrally formed on the side of the lock body 9.

The hook 8 has the striker 7 on its rear surface.
It has a slope 8a that guides it when engaged with the holding part 10, and is held against the holding part 10 by being biased in the projecting direction by a spring 14. Reference numeral 15 is a stopper for holding the hook 8 in a protruding state.

An inclined surface 16 is formed on the upper surface of the hook 8 and acts as a cam surface for sliding the hook 8 (moving in the direction of arrow Y). That is, the hook 8 is configured to slide when a pressing force is applied to the inclined part 16 as the inclined part 16 escapes.

On the other hand, a connecting rod 17 is connected to the key cylinder 13 and has a contacting portion 18 formed at one end thereof to be brought into contact with the inclined portion 16 . Applicable contact part 18
protrudes forward at right angles from the other end of the connecting rod 17, and has a certain thickness so that it comes into contact with the inclined portion 16 when the key cylinder 13 is unlocked. Furthermore, this connecting rod 17 has a small rod portion 17a on the contact portion 18 side and a large rod portion 17 on the key cylinder 13 side.
It consists of b. This small rod portion 17a is made thin in order to secure a gap between the upper surface of the lock body 9 and the upper surface of the lock body 9 to allow the downward movement of the abutting portion 18 when the abutting portion 18 is in contact with the inclined portion 16. On the other hand, when the key cylinder 13 is locked (that is, when the connecting rod 17 is moved in the direction of arrow It is formed thick so that it can be held in place by the pieces 19.

Further, a swing type knob 11 is pivotally supported on the bearing pieces 12, 12 via a pin 20 so as to be rotatable in an arc. Reference numeral 21 is a bearing piece on the knob 11 side.

At the center of the upper end of this knob 11, the inclined portion 1
An engagement piece 22 is integrally provided to apply a rotational motion to the contact portion 6 via the abutting portion 18 . That is, when the key cylinder 13 is unlocked, the engagement piece 22 rotates in an arc as the knob 11 swings in the direction of the arrow Z, and engages the hook 8 via the contact portion 18 of the connecting rod 17. A rotational movement is applied to the inclined portion 16, and the hook 8 is slid in the direction of the arrow Y.

In the drawing, reference numeral 23 indicates a spring for returning the knob 11, and 24 indicates a spring for returning the lock body 9 to the lid 3.
a boss onto which the fastener 25 is screwed in order to fix it to the
26 is an opening formed in the lid 3 to allow the striker 7 to enter and exit.

Next, the operation of the illustrated locking device 5 will be explained.

() When the key cylinder is unlocked At this time, the contact portion 8 of the connecting rod 7 is interposed between the inclined portion 16 of the hook 8 and the engagement piece 22 of the knob 11, as shown by the solid line in FIG. There is. In other words, the contact portion 18 is positioned within the rotation locus of the engagement piece 22.

When the knob 11 is swung in the direction of the arrow Z in this state, the inclined portion 1
A rotational movement is applied to the hook 6 through the abutting portion 18, and the rotational movement is converted into a horizontal sliding movement by the inclined portion 16, thereby causing the hook 8 to slide in the direction of the arrow Y. Therefore, the engagement between the hook 8 and the striker 7 is released, and the lid 3 is opened.

() When the key cylinder is locked At this time, the connecting rod 17 is operated in the direction of the arrow X by the rotation of the key cylinder 13 in the direction of the arrow M.
The contact portion 18 is positioned outside the rotational trajectory of the engagement piece 22, as shown by the chain line in FIG.

When the knob 11 is swung in the direction of arrow Z in this state, the engagement piece 22 rotates in an arc, but the contact portion 1
This results in a blank operation (that is, a blank firing) by an angle corresponding to the amount that 8 was present, and it becomes impossible to apply a rotational movement to the inclined portion 16. Therefore, hook 8
The engaged state of the striker 7 is maintained, and the lid 3 cannot be opened.

Due to the above-mentioned action, even if the user swings the knob 11 without knowing that the key cylinder 13 is in the locked state, the engaging piece 22 will hit blankly as described above, resulting in an unreasonable force being applied to the knob 11. has no effect.

Furthermore, since the locking device 5 of this embodiment employs the swinging type knob 11 and the horizontal sliding type hook 8, a space for the horizontal sliding stroke is required, but the vertical dimension is This makes it possible to make the locking device compact and provides a locking device 5 that is most suitable for a device whose vertical dimension is limited, such as a lid 3 for a glove box.

It should be noted that the lock structure of the glove box of the present invention is not limited to the illustrated embodiment, and it goes without saying that the design can be changed without departing from the gist of the invention.

(Effects of the invention) As described above, according to the invention, the rotating movement of the engaging piece of the swinging type knob provided on the lid is connected to the key cylinder by the inclined part formed on the horizontal sliding type hook. The hook is actuated through the abutting portion of the connecting rod, and the hook is horizontally slid to disengage from the striker on the glove box body side. By displacing the contact portion outside of the rotational trajectory of the engaging piece, the engaging piece is driven dry when the knob swings, so that the vertical dimension is reduced from the point where the operating stroke of the hook becomes horizontal. A small lock structure can be obtained, which has the practical effect of ensuring sufficient operating space below the knob even when installed in an item where the vertical dimension is restricted, such as the lid of a glove box.
