Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an operating mechanism for a rotary latch in a glove box locking device for an automobile or the like.

(Prior art) Conventionally, this type of glove box lock device was disclosed in Utility Application No. 155369/1983 (Utility Model Application No. 62-63362).
There is something like the one shown. That is, as shown in FIG.
The striker 17 is rotated counterclockwise by the biasing force 5, and the striker 17 is thereby released from the rotating latch 14, allowing the lid to be opened. When the pulling operation of the handle 13 is completed, the handle 13 is rotated clockwise by the biasing force of the handle spring 16 and returned to its original position.

(Problem to be solved by the invention) However, in the conventional device described above, although there is a handle spring for returning the handle, the rotary latch is separately rotated in the direction of opening the striker. Therefore, a separate spring must be provided for this purpose, which results in a complicated structure and shape, resulting in a disadvantage that it takes a lot of effort to assemble.

(Purpose of the present invention) In view of the above-mentioned drawbacks of the prior art, the present invention eliminates the latch spring and uses a handle spring to rotate the rotary latch in the direction of opening the striker. The object of the present invention is to provide a glove box locking device which has a simple structure and can be easily assembled.

(Structure of the invention) Therefore, in the present invention, a part of the handle spring wound around the handle shaft that supports the handle of the glove box locking device is biased in the direction in which the rotary latch opens the striker. The rotary latch is engaged with the rotary latch.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. 1 is a front view showing a glove box locking device according to the present invention, FIG. 2 is a sectional view taken along line A-A in the locked position, FIG. 3 is a sectional view taken along line A-A when the handle is pulled, and FIG. The figure shows A- in the unlocked position.
It is an A sectional view.

As shown in Figures 1 and 2, the handle spindle 1
The upper back surface of the handle 3, which is pivoted on the handlebar 3 and biased clockwise in FIG.
A chevron-shaped cam portion 4 consisting of is provided in a protruding manner. Further, the lower part of the rotary latch 7 is supported by the latch support shaft 5, and is biased counterclockwise in FIG. is provided with a receiving surface 8 that comes into sliding contact with the cam portion 4 provided on the handle 3. It should be noted that the upper part of the rotary latch 7 is approximately U.
A striker engagement groove 9 in the shape of a letter is provided. Here, as shown in FIGS. 2 to 4, the cam portion 4 provided on the handle 3 and the receiving surface 8 of the rotary latch 7 slide into contact with each other by pulling the handle 3 and are engaged in a detachable manner. The sliding surface 4a on the cam portion 4 side and the sliding surface 8a on the receiving surface 8 side of the rotary latch 7 are both formed in an arc shape centered on the handle shaft 1.

Further, as shown in FIGS. 3 and 4, the cam portion 4 is formed to separate from the receiving surface 8 of the rotary latch 7 when the pulling operation of the handle 3 reaches a predetermined angle. Furthermore, a chevron-shaped latch cam portion 7a is provided at the lower part of the receiving surface 8 of the rotary latch 7.

In addition, as shown in FIGS. 1 and 2, the handle 3
On the back side, the left and right ends 1a of the handle spindle 1,
A base 10 that pivotally supports 1b and is fixed to the back side of the lid body.
is provided. Both ends of the handle spring 2 wound around the handle shaft 1 are engaged with the upper surfaces 3a and 3b of the handle 3, and the approximately central portion is
It is sandwiched between the U-shaped striker receiving portion 12 and extends toward the rotary latch 7, and is engaged with the rotary latch 7 in a manner that wraps around the rotary latch 7. Further, a part of the extending part 2a of the handle spring 2 is formed with a rattling prevention part 2b having a shape facing into the striker engagement groove 9, so that it comes into contact with and locks the striker 11 when the handle spring 2 is locked. There is.

Next, the operation of this embodiment will be explained.

(a) First, the case of opening the glove box will be explained. When the handle 3 is pulled from the locked state shown in FIG. 2, the sliding surface 4a of the cam portion 4 provided on the handle 3 slides against the sliding surface 8a of the receiving surface 8 of the rotary latch 7 and moves. , the position of the cam portion 4 is from the sliding surface 4a to the separation surface 4.
The movement is not transmitted to the rotary latch 7 until reaching b.

Next, as shown in FIG. 3, when the pulling operation of the handle 3 reaches a predetermined angle and the position of the cam portion 4 reaches the detachment surface 4b from the sliding surface 4a, the cam portion 4 is separated from the receiving surface 8 of the rotary latch 7. Leave and handle 3
and the rotation latch 7 is disengaged. and,
The rotary latch 7, which is biased counterclockwise by the extension 2a of the handle spring 2, rotates until the abutting groove 7b of the rotary latch 7 abuts against the cam 4, and then stops. If the handle 3 is further pulled from this state, the striker 11 is disengaged from the striker engagement groove 9 of the rotary latch 7, and the engagement between the two is released and the lid can be opened (FIG. 4).

(b) Next, the case of closing the glove box will be explained. When the lid is pushed toward the glove box from the opened state, the striker engagement groove 9 of the rotary latch 7 provided on the lid hits the striker 11 provided on the glove box, as shown in FIG. Contact, striker 11
The rotary latch 7 rotates clockwise about the rotary latch support shaft 5 in a state that includes the rotary latch 7 . At that time, the latch cam portion 7a is connected to the cam portion 4 of the handle 3.
As the rotary latch 7 rotates, the handle 3 rotates counterclockwise about the handle shaft 1 as a fulcrum (FIG. 3). When the latch cam portion 7a passes over the detachment surface 4b of the cam portion 4 of the handle 3, the handle 3, biased clockwise by the handle spring 2, rotates clockwise (FIG. 2). In this state, the striker 11 on the glove box side engages with the rotating latch 7 on the lid side, and the glove box is locked so that it cannot be removed. Here, the rotation latch 7 has a handle spring 2.
The extending portion 2a of the handle is always biased counterclockwise, but in the locked state, the cam portion 4 of the handle 3 acts as a stopper to prevent the handle from rotating counterclockwise. There is.

In addition, in the above-mentioned locked state, as shown in FIG. 2, the striker 11 comes into contact with the rattling prevention portion 2b of the handle spring 2, so that rattling between the glove box side and the lid body side is prevented. .

(Effects of the invention) As mentioned above, this invention eliminates the latch spring and allows the handle spring to rotate the rotary latch in the direction of opening the striker, which simplifies the structure of the device itself and makes assembly easier. This has the great effect of saving time and effort.
