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) As a lock structure of a glove box provided on the instrument panel at the front of the vehicle body, as described in Japanese Utility Model Application Publication No. 49-3235, a striker fixedly provided on the glove box body side is used. It is well known that a hook that is swingably provided on the lid side is engaged.

However, with such a lock structure, the engagement between the striker and the hook tends to be insufficient.
When a passenger hits the lid during a vehicle collision, the lid may open inadvertently, creating a risk of danger. Furthermore, since the fixed striker and the swingable hook are simply engaged, contact noise between the two may be generated as the vehicle vibrates, which may cause abnormal noise.

(Purpose of the invention) This invention was made in view of the above points.
To provide a lock structure for a glove box, which has a strong lock structure that prevents the engagement between a striker and a hook from being easily released even when an impact is applied to the lid, and which can also prevent the generation of abnormal noise. (Means for achieving the purpose) In the present invention, as a means to achieve the above purpose, a striker rotatably provided on the glove box body and a striker that engages when the lid is closed are provided. A second hook that follows the swing of a knob rotatably provided on the lid is pivotally supported on a first hook fixed to the lid, and the second hook has the striker and the striker on one end side. The two-pronged engaging part that engages,
an interlocking part that follows the swinging of the knob is formed on the other end side, and the engaging part is a holding part that presses the striker to maintain engagement between the striker and the first hook; and a claw portion that presses and rotates the striker when the knob swings in the opening direction to release the engagement between the striker and the first hook.

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

(1) When the lid is closed, the striker, which is rotatably provided on the glove box body side, is firmly engaged and held by the holding part of the engaging part formed on the second hook and the first hook. Since the striker sometimes follows the deformation of the lid, separation of the striker is prevented.

(2) Since the striker is firmly engaged and held by the holding portions of the first hook and the second hook, no abnormal noise is generated even when the vehicle vibrates.

(3) When the knob is swung in the opening direction, the striker is pressed and rotated by the claw portion of the engagement portion formed on the second hook, and the engagement between the striker and the first hook is easily released.

(Embodiments) Hereinafter, some 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 the lid 3 of the glove box 2 provided in the instrument panel 1 in the closed state at the front of the vehicle body (see FIG. 7).

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.

A first embodiment of the invention is shown in FIGS. 1-3.

The lock device 5 in this embodiment includes a striker 7 rotatably provided on the glove box body 6 side, and a first hook 8 fixed to the lid 3 to engage with the striker 7 when the lid 3 is closed.
and a knob 9 rotatably supported on the lid 3 (actually, the rear end of the first hook 8 fixed to the lid 3);
A second hook 10 rotatably supported on the hook 8
It is composed of:

The first hook 8 has a gutter-like boss 1 formed on the lid 3 with mounting pieces 11 protruding from both sides thereof.
It is fixed to the lid 3 by fastening it to the striker 2 using a fastening element 13, and the front end thereof has a locking part 14, 1 for locking the striker 7.
4 is formed. The front end surface of the first hook 8 serves as a guide surface 15 for guiding the lower end of the striker 7 when the lid 3 is closed.

The second hook 10 is disposed within the first hook 8 and rotatably supported at the center of the first hook 8 via a pin 16, and is located at one end (i.e., front end) of the second hook 10. is formed with a bifurcated engaging portion 18 that engages with the striker 7, while the other end (i.e., rear end side) is formed with an engaging piece 17 protruding from the knob 9. An interlocking portion 19 is formed to follow the swinging movement of the knob 9.

The engaging portion 18 includes a holding portion 18a that is located on the upper side and presses the striker 7 to maintain engagement between the striker 7 and the first hook 8 (specifically, the locking portion 14); The striker 7 is rotated in the direction of the arrow Y as the second hook 10 is rotated in the direction of the arrow Y as the knob 9 swings in the opening direction (in the direction of the arrow X). A claw portion 18 that is pressed and rotated to release the engagement between the striker 7 and the first hook 8 (more specifically, the locking portion 14)
It is composed of b.

Further, the second hook 10 is biased in the engagement direction by the return spring 20, while the knob 9
, the engagement piece 17 is connected to the interlocking part 1 of the second hook 10.
It is biased by a spring 21 for preventing backlash so as to come into contact with the top of 9.

In the drawing, 22 is a spring that urges the striker 7 in the engagement direction, 23 is a stopper that positions the striker 7 at a position where it can come into contact with the guide surface 15 of the first hook 8 when the lid is closed, and 24 is a knob 9.
A bearing piece 25 protruding from is a pin for pivotally supporting the knob 9.

The locking device of the first embodiment operates as follows.

When the lid 3 is in the closed state, as shown in FIG.
4, and the engaging portion 1 of the second hook 10
8, and is held in an extremely firm engagement state. Therefore, in this state, the striker 7 will not come off even if a force such as longitudinal or torsional force is applied, and the lid 3 will not open inadvertently even in the event of a secondary collision with the lid 3. Further, since the holding portion 18a of the second hook 10 presses the striker 7, the engagement portion between the two is prevented from wobbling.

Next, when trying to open lid 3,
When the knob 9 is swung in the direction of the arrow X, the interlocking portion 19 of the second hook 10 is pushed down by the engaging piece 17 of the knob 9, and the second hook 10 is rotated in an arc in the direction of the arrow Y. Then, as shown in FIG. 2, the striker 7 is pushed up and rotated by the claw portion 18b of the second hook 10, and the engagement with the locking portion 14 of the first hook 8 is released, and the lid 3 is opened. It becomes possible.

A second embodiment of the invention is shown in FIGS. 4-6. In this case, the pin 16 that pivotally supports the second hook 10 is connected to the side walls 8a, 8 of the first hook 8.
The second hook 10 is engaged with and installed in elongated holes 26, 26 formed in the second hook 10, and is slidable in the front and rear directions. Moreover, the interlocking part 19 of the second hook 10
is the pin 25 that is the center of rotation of the knob 9.
The second hook 10 is rotatably supported on a bearing piece 27 protruding from a lower position, so that the second hook 10 can slide in the direction of the arrow Z following the swinging of the knob 9 in the direction of the arrow X. has been done. Reference numeral 28 is a return spring for returning the knob. The rest of the configuration is the same as that of the first embodiment, so the explanation thereof will be omitted.

The locking device of the second embodiment operates as follows.

When the lid 3 is in the closed state, the striker 7 is held in an extremely firmly engaged state by the locking portion 14 of the first hook 8 and the holding portion 18a of the second hook 10, as in the first embodiment. (See Figure 4).

Next, when trying to open lid 3,
When the knob 9 is swung in the direction of the arrow X, the second hook 10 connected to the knob 9 via the interlocking part 19 is slid in the direction of the arrow Z, and as shown in FIG. 2 Claw portion 1 of hook 10
8b and rotates, and the first hook 8
The engagement with the locking portion 14 is released, and the lid 3 can be opened.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that the design can be changed without departing from the gist of the invention.

(Effect of the invention) As described above, according to the invention, when the lid is closed, the striker on the glove box body side is
When it is engaged with the first hook provided on the lid side, it can be pressed by the holding part of the second hook pivotally supported on the first hook to maintain a firm engaged state. Even if force is applied in the longitudinal or torsional direction due to a secondary collision during a vehicle collision, the striker will no longer disengage, preventing the danger of a secondary collision due to the lid opening inadvertently. There is a practical effect that it can be done.

Furthermore, since the striker is pressed by the holding portion of the second hook when the lid is closed, the contact noise of the engaging portion is suppressed, and there is also the effect that abnormal noise can be prevented from occurring.

Furthermore, by swinging the knob in the opening direction, the claw portion of the second hook presses the striker and rotates it, thereby releasing the engagement with the first hook. Another advantage is that it can be done extremely smoothly.
