Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a glove box locking device used in a vehicle. More specifically, the present invention relates to a glove box locking device that can be provided with a cylinder key to prevent theft and can be manufactured at low cost.
[0002]
[Prior art]
FIG. 4 shows a cross-sectional view of an example of a glove box and its locking device used in a conventional vehicle. In the figure, reference numeral 1 denotes an instrument panel (or dashboard) of a vehicle, and 2 denotes a glove box provided on the instrument panel or dashboard. The lower part of the glove box 2 is supported by a hinge pin 3 so as to be pivotable. The glove box 2 is openable and closable. Moreover, the striker 5 which the said locking device 4 latches is provided in the instrument panel or dashboard.
[0003]
The lock device 4 is provided with a hook 6, a ratchet 7, and a knob 8 that engage with the striker 5. During normal use, pulling the knob 8 in the direction of arrow A causes the lever formed on the knob 8 to rotate the ratchet 7 to disengage the striker 5 and pull the glove box 2 forward. Can do. When the key is locked, the key cylinder is rotated by a key (not shown) so that the shaft assembled to the key cylinder moves laterally to the place where the lever of the knob 8 does not touch. The 8 lever is swung and the shaft is not pushed down. Therefore, the ratchet does not rotate and the lock is not released.
[0004]
[Problems to be solved by the invention]
The conventional glove box locking device as described above is effective in preventing theft, but in terms of strength, the hook 6 is formed by die casting, the ratchet 7 is formed by iron, and the number of components is also increased. There is a problem that the cost of the product is increased because of about 10 points. For this reason, recently, resin lock devices that can be manufactured at low cost have been developed.
[0005]
In view of the above-described conventional problems, an object of the present invention is to realize a glove box locking device having a small number of components, low cost, and excellent antitheft.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, claim 1 of the present invention provides a base 21 having a box shape attached to a glove box used in a vehicle, and a ratchet supported on the base 21 by a ratchet rotating shaft 27 so as to be swingable. 22 and a knob 23 that is supported by a shaft different from the ratchet rotation shaft 27 and can rotate the ratchet 22, and a key cylinder 24 that is provided on the knob 23 and that can rotate as the knob 23 rotates. And a striker 34 provided on the vehicle body to which the ratchet 22 can be engaged and disengaged. The ratchet 22 includes a lever portion 28 that is normally driven by the knob 23 and a key cylinder only when the key is locked. formed projection 30 which engages the 24, the key cylinder 24 has projections 35 are provided, wherein at the time of key lock key 2 places and the abutment of the projection 30 of the wall 21a and the ratchet 22 of the protrusion 35 of the cylinder 24 is the base 21, the interference to prevent rotation of the ratchet 22, engagement of the said ratchet 22 striker 34 It is possible to prevent the release of the match. A second aspect of the present invention is characterized in that the base 21, the ratchet 22, and the knob 23 are made of resin. According to a third aspect of the present invention, the key cylinder 24 can be rotated 90 ° by a key.
[0007]
By adopting this configuration, it is possible to obtain a glove box locking device that has a small number of components, is low in cost, and is excellent in theft prevention.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a view showing an embodiment of a glove box locking device according to the present invention, wherein (a) is a front perspective view, (b) is a rear perspective view, and (c) is a ratchet perspective view. In the present embodiment, as shown in the figure, a base 21 fixed to a glove box, a ratchet 22 rotatably supported by the base 21, a knob 23 for driving the ratchet 22, and the knob 23 And a cylinder key 24 that is provided to lock or unlock the knob. The base 21, ratchet 22, and knob 23 are preferably made of resin.
[0009]
The ratchet 22 has a hook shape, and the hook-like portion 25 is connected to the ratchet rotating shaft 27 through a connecting portion 26 as shown in FIG. Further, a lever portion 28 is provided on the side of the connecting portion 26, and a planar portion 29 that is pressed and driven by the knob 23 and a protrusion 30 that contacts and locks the key cylinder are formed on the lever portion 28. Yes.
[0010]
Further, in the present embodiment, as shown in the cross-sectional views of FIGS. 2B, 2C, and 2D, the ratchet 22 is supported by the ratchet rotating shaft 27, and the ratchet return spring 31 is used to indicate the arrow as shown in FIG. It is biased in the A direction. The knob 23 has a shape substantially covering the front surface of the base 21, is supported by a shaft 32 different from the ratchet rotation shaft 27, and is urged in the direction of arrow B by a knob return spring 33. Reference numeral 34 denotes a striker provided in the vehicle. Further, as shown in FIG. 4D, the key cylinder 24 has a protrusion 35 formed at the tip, and the protrusion 35 is engaged with a flat portion 29 of the lever portion 28 formed on the ratchet 22. The key cylinder 24 is rotated 90 ° clockwise by the key when locked.
[0011]
The operation of the present embodiment configured as described above will be described with reference to FIG. FIG. 5A is a front view, FIG. 5B is a cross-sectional view taken along line bb in FIG. 5A, and FIG. 5C is a cross-sectional view taken along line cc in FIG.
First, during normal use, as shown in FIG. 5B, the key cylinder 24 has its projection 35 positioned at the top. Accordingly, when the knob 23 is rotated in the direction of arrow C, the flat surface portion 29 of the lever portion 28 of the ratchet 22 is pressed downward by the projection 35 of the key cylinder 24, and is rotated to the position shown in FIG. And the striker 34 can be disengaged to open the glove box.
[0012]
When the key cylinder 24 is locked, the key cylinder 24 is rotated by 90 ° from the normal use state, and the protrusion 35 is positioned at the height of the center line of the key cylinder 24 as shown in FIG. Even if it is attempted to move the knob 23 in this state, the projection 35 of the key cylinder 24 hits the wall 21a of the base 21 and cannot be rotated. Further, the ratchet 22 cannot be moved with its protrusion 30 abutting against the protrusion 35 of the key cylinder 24. That is, the lock device is locked. In order to release the lock, the key cylinder 24 may be rotated by 90 ° to return to the state shown in FIG.
[0013]
【The invention's effect】
According to the glove box locking device of the present invention, the number of components can be reduced, and it can be manufactured at low cost, and can be locked. In this case, the knob and the ratchet cannot be moved independently, and theft is excellent. Prevention becomes possible.
