TECHNICAL FIELD OF THE INVENTION
The present invention relates to a glove box locking device. More specifically, the present invention relates to a glove box locking device that enables a ratchet to be engaged with a striker provided in a vehicle to be manufactured accurately and at low cost.
[0002]
[Prior art]
FIG. 3 shows a cross-sectional view of an example of a glove box and a lock device used in a conventional vehicle. In the figure, reference numeral 1 denotes an instrument panel (or dashboard) of a vehicle, 2 denotes a glove box, and the glove box is rotatably supported by the instrument panel 1 by hinge pins 3. The glove box 2 is provided with a lock device 4, and the instrument panel 1 is provided with a striker 5 to which the lock device 4 is locked.
[0003]
Further, the lock device 4 is provided with a hook 6 and a ratchet 7 which are engaged with the striker 5, and the ratchet 7 is fixed to a knob 8, and the knob 8 is turned around the pin 9 in the direction of arrow A. As a result, the engagement with the striker 5 is released, and the glove box 2 can be pulled out forward. In the lock device 4 configured as described above, the hook 6 is made of die-cast and the ratchet 7 is made of iron in terms of strength. This has the disadvantage of increasing the cost of the product. For this reason, a low-cost resin lock device has recently been developed.
[0004]
FIG. 4 is a view showing a lock device made of resin. As shown in a front perspective view of FIG. 4A, a rear perspective view of FIG. 4B, and a cross-sectional view of FIG. 4C, the locking device is rotatable with respect to a base 10 fixed to a glove box. , A knob 12 for driving the ratchet 11, and a striker 13 provided in the vehicle. The ratchet 11 has a hook shape, is rotatably supported on the base 10 by a ratchet rotating shaft 14, and the knob 12 has a shape substantially covering the front surface of the base 10, and is different from the ratchet rotating shaft 14. It is rotatably supported on the base 10 by a shaft, and is urged in the direction of arrow A by a spring (not shown).
[0005]
The ratchet 11 is urged in the direction of arrow B by a spring (not shown). The ratchet 11 can be engaged with the striker 13 at the hook. In order to release the engagement, the lower arm of the knob 12 is rotated in the direction opposite to the arrow A as shown in FIG. The flat portion 11a formed on the ratchet 11 is pressed to rotate the ratchet 11 in the direction opposite to the arrow B in FIG. 3 (c) to release the engagement with the striker 13, thereby opening the glove box. be able to.
[0006]
[Problems to be solved by the invention]
In the conventional lock device for a glove box as described above, in order to form a complicated ratchet having a shape as shown in FIG. 4 (d), as shown in FIG. Since two slide cores 18 and 19 moving in opposite directions are required, the mold becomes complicated and the wall thickness increases, so that the surface accuracy of the ratchet striker contact surface 15 shown in FIG. In addition, there is a problem that the mold manufacturing cost increases.
[0007]
SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to realize a glove box locking device that can easily produce ratchets at low cost.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a first aspect of the present invention is to provide a box-like base 21 attached to a glove box used in a vehicle, and a body 21 supported by the base 21 so as to be swingable by a ratchet rotating shaft 25. A glove box comprising: a ratchet 22 that can be disengaged from a striker 24 provided on the vehicle; and a knob 23 that is supported on a shaft different from the ratchet rotation shaft 25 and can rotate the ratchet 22. The ratchet 22 includes a striker holding portion 26 for engaging with the striker 24, a hook portion 28 having a striker contact surface 27 formed in a U-shape, a hook portion 28 and a ratchet rotation shaft 25. And a connecting portion 29 connecting the striker and the striker contact surface 27 of the hook portion 28. The distance between the two divided striker contact surfaces 27 is substantially equal to the width of the striker holding portion 26 of the hook portion 28.
[0009]
By adopting this configuration, it is possible to realize a glove box locking device that can easily produce ratchet accuracy and can be manufactured at low cost.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a view showing an embodiment of a glove box locking device according to the present invention, in which (a) is a front perspective view, (b) is a rear perspective view, and (c) is a line cc in FIG. And (d) is a perspective view of the ratchet. The present embodiment includes a base 21 fixed to a glove box, a ratchet 22 rotatably supported by the base 21, and a knob 23 for driving the ratchet 22. Reference numeral 24 denotes a striker provided on the vehicle.
[0011]
The ratchet 22 has a hook shape, is supported by a ratchet rotating shaft 25 and is urged in the direction of arrow B by a spring (not shown), and the knob 23 has a shape substantially covering the front surface of the base 21. It is supported on a shaft different from the ratchet rotation shaft 25 and is urged in the direction of arrow A by a spring (not shown). The above is the same as the conventional example described with reference to FIG.
[0012]
The present embodiment is characterized in that a ratchet 22 is provided. The ratchet 22 has a striker holding portion 26 which is engaged with a striker 24, a hook portion 28 having a striker contact surface 27 formed in a U-shape, and a hook portion 28. A connecting portion 29 for connecting the ratchet rotating shaft 25 is provided, and the striker contact surface 27 of the ratchet 22 is divided into two as shown in FIG. The distance between the two divided striker contact surfaces 27 is substantially equal to the width of the striker holding portion 26 of the hook 28.
[0013]
The present embodiment configured as described above can be formed by a mold as shown in FIG. 3A is a longitudinal sectional view, FIG. 3B is a sectional view taken along line bb in FIG. 3A, and FIG. 3C is a sectional view taken along line cc in FIG. The die includes a lower die 30, an upper die 31, and a slide core 32. The lower die 30 forms the lower part of the ratchet 22, the upper die 31 forms the upper part of the ratchet 22 and the striker contact surface, and the slide core 32 forms a striker holding part. To move to.
[0014]
As described above, since the present mold includes the three molds of the upper, lower, and core, the structure is simpler than that of the conventional mold using four molds described with reference to FIG. Since the contact surface is formed by one upper mold, the accuracy can be improved and the cost can be reduced. Therefore, the ratchet using the present mold is also inexpensive.
[0015]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the locking device of the glove box of this invention, the metal mold | die for forming this ratchet can be simplified by dividing the striker contact surface of a ratchet into two, and, thereby, the ratchet striker contact surface. Can be improved, and it can be manufactured at low cost.
