Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a locking device for a glove box of an automobile or the like.

(Prior art) The opening/closing mechanism of a glove box installed in the interior of a vehicle is such that when a handle attached to the lid is pulled, a slider on the lid side that engages with a striker on the box side is pulled in using a connecting piece or the like, and the slider is removed from the striker. The slider collides with the striker and moves downward against the biasing spring when the cover is closed, and after the striker passes over the slider, the slider moves downward again to hold the striker. is being used.

Conventionally, as a locking device in which a cylinder lock is attached to the opening/closing mechanism of such a glove box, there is known, for example, one disclosed in Japanese Utility Model Application No. 58-62753. That is, both the slider and the main body slidably supporting the slider are provided with elongated holes extending vertically and penetrating horizontally. A swinging piece whose one end engages with a crank formed in the cylinder lock rotor is inserted into this elongated hole. The other end of this swinging piece engages with the protrusion of the manual handle when the cylinder lock is in the unlocked position, and is disengaged from the protrusion of the manual handle when the cylinder lock is in the locked position. ing.

(Problem to be solved by the invention) However, in the conventional glove box locking device described above, the swinging piece is inserted into a long hole formed in the slider, and the swinging piece and the slider are always interlocked. Because of this structure, the swinging piece swings every time the lid is closed, resulting in a problem that a rattling sound is generated.

(Objective of the Present Invention) In view of the above-mentioned problems in the prior art, an object of the present invention is to provide a glove box locking device that does not generate a rattling sound when the lid is closed.

(Means for solving the problem) Therefore, in this invention, a cylinder lock is attached to the opening/closing device, which moves the slider on the lid side downward by pulling the handle and disengages from the striker on the box side. A locking device for a glove box that cannot be opened when locked includes a slider having a slider pin on the back side, a handle having a handle protrusion on the back side located between the cylinder lock rotor and the slider, and a handle of the rotor. a swinging piece having an elongated protrusion-containing portion that includes a handle protrusion and one end of which is pivotally supported by an eccentric pin provided on the back side; In the locked position, it faces the top of the slider pin, while in the locked position of the cylinder lock, it is arranged to separate from the top of the slider pin.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a rear view of the glove box locking device according to the present invention in an unlocked state, FIG. 2 is a sectional view taken along the line AA in FIG. 1, and FIG. 3 is a rear view of the glove box locking device in a locked state.

As shown in FIGS. 1 and 2, one end of a swing piece 5 is rotatably attached to an eccentric pin 4 protruding from the back surface of a rotor 3 of a cylinder lock 2 attached to an opening/closing device 1. The rotor 3 is supported so that it can move forward and backward by rotating the rotor 3. An elongated protrusion-containing portion 6 is provided approximately at the center of the swinging piece 5.
The tips of handle protrusions 8 fixed to the back surface of the handle 7 of the glove box are inserted and included in the protrusion containing portions 6. In addition, this rocking piece 5
As shown in FIG. 1, when the cylinder lock 2 is in the unlocked position, the other end is positioned above a slider pin 10 fixed to the back surface of a slider 9 which is biased by a spring 12 and can move downward. There is. Further, as shown in FIG. 3, when the cylinder lock 2 is in the locked position, the other end of the swinging piece 5 is moved downwardly by the slider pin 10, which moves downward together with the slider 9 due to the rotation of the rotor 3.
It is designed to separate from the upper part (on the operating trajectory). A hook-shaped striker receiving part 13 is provided at the upper part of the case 11 that houses the spring 12 and the lower part of the slider 9, and the handle 7 is attached to the shaft rod 15 around which the spring 19 is wound, at the front of this case 11. One end of the spring 19 is engaged with the back surface of the handle 7, and the other end is engaged with the front surface of the case 11, thereby biasing the handle 7.
In this way, by providing the handle protrusion 8 between the rotor 3 and the slider 9, the width dimension of the device main body can be reduced, and the operating angle of the handle 7 can also be reduced. By shortening the length, the dimension in the thickness direction of the device body can also be reduced, and as a result, the locking device can be made smaller.

Furthermore, the handle 7 is in the locked state shown in FIG.
Even if the glove box is pulled and the handle protrusion 8 is pushed down, the glove box will not open, so if an erroneous operation is performed by moving the cylinder lock 2 to the unlocked position while pulling the handle 7 and attempting to open the lid, the above operation will not work. If allowed, the other end of the swinging piece 5 on the slider pin 10 side will sink into the lower part of the slider pin 10, causing a failure. To prevent this, the rocking piece 5 has an engaging protrusion 18.
is provided so as to be able to engage with a stopper 17 provided on the back surface of the case 11.

Next, the operation of this embodiment will be explained.

(a) First, when opening a lid that is closed in a locked state, insert a key (not shown) into the key insertion hole 16 shown in FIG. When the swinging piece 5 is rotated to the right in the figure and moved to the unlocked position as shown in FIG. 1, the other end of the swinging piece 5 will be located above the slider pin 10 (on the operating trajectory). In this state, when the handle 7 is pulled, the handle protrusion 8 pushes down the swinging piece 5 via the protrusion inclusion part 6 of the swinging piece 5, and as a result,
The slider pin 10 is also pushed down (Fig.
one-dot chain line state) The slider 9 moves downward. As a result, the striker 14 on the box side and the striker receiving portion 13 on the lid side are disengaged, and the lid can be opened.

(b) Next, when closing and locking the lid from the opened state, press the lid against the box side and press the striker 14 and slider 9 on the box side.
When the slider 9 collides with the spring 12, the slider 9 moves downward against the spring 12, the striker 14 climbs over the slider 9, and the slider 9 moves against the spring 12 again.
The striker 14 is held between the slider 9 and the striker receiving portion 13. still,
When the lid is closed, the swinging piece 5 is held by the handle protrusion 8, and as a result, the swinging piece 5 does not swing unnecessarily, so there is no rattling noise. will never occur.
In this closed state, when the cylinder lock 2 is moved to the locked position as shown in FIG. 3, the other end of the swinging piece 5 separates from the upper part of the slider pin 10, which is on the operating locus. As a result, even if the handle 7 is pulled and the swinging piece 5 is pushed down by the handle protrusion 8, the slider 9 does not move downward (as shown by the dashed line in FIG. 3), and the lid cannot be opened.

(c) Next, when closing the lid that is open with the cylinder lock 2 still in the locked position, the slider 9 itself will be moved downward by external force without being restricted in any way, as shown in Figure 3. Therefore, the lid can be closed using the same action as in (b).

(d) Next, if the cylinder lock 2 is in the locked position, pull the handle 7, move the cylinder lock 2 to the unlocked position, and attempt to open the lid. The engaging protrusion 18 of No. 5 is locked by the stopper 17 to restrict further rotation and prevent erroneous operation.

(Effects of the invention) As described above, in this invention, a cylinder lock is attached to the opening/closing device that moves the slider on the lid side downward by pulling the handle and disengages from the striker on the box side. A locking device for a glove box that sometimes cannot be opened has a slider with a slider pin on the back side, a handle with a handle protrusion on the back side located between the cylinder lock rotor and the slider, and a handle on the back side of the rotor. a swinging piece having an elongated protrusion-containing portion that includes a handle protrusion, one end of which is pivotally supported on an eccentric pin provided, and the swinging end of the swinging piece is in the unlocked position of the cylinder lock. The swing piece faces the top of the slider pin when the cylinder lock is in the locked position, and is separated from the top of the slider pin when the cylinder lock is in the locked position.The swing piece only moves with the slider when the lid is opened, and is moved by the handle protrusion when the lid is closed. Since the swinging piece is held in place, the swinging piece does not swing unnecessarily when the lid is closed, and as a result,
This has the excellent effect of not causing any rattling noise. In addition, by providing the handle protrusion between the cylinder lock rotor and the slider, the width of the device body can be reduced, and the operating angle of the handle can also be reduced, so the length of the handle protrusion can be shortened. As a result, the size of the device main body in the thickness direction can be reduced, and as a result, there is an excellent effect that the locking device can be made smaller.
