Description

TECHNICAL FIELD The present invention relates to a glove box for an automobile, and more particularly to a device for locking and unlocking an opening / closing body of the glove box.

-Prior Art-As is well known, in a glove box provided in an instrument panel of an automobile, for example, the actual open sho 60-1438 is used.
As disclosed in Japanese Patent Laid-Open No. 56-56, a locking device and a steering wheel are usually arranged at the center of the lid of the glove box in the width direction to be opened and closed by a driver or the like. That is, FIGS. 6 and 7 show the glove box disclosed in the publication, and the lower part of the lid B of the glove box provided on one side of the instrument panel A is hinged to the instrument panel A so that the lid can be opened and closed. A lock device D that engages with the striker C inside the glove box is installed at the upper edge of the central portion of the lid B in the width direction. The escutcheon portion b of the lid B corresponding to the lock device D
Includes a handle E for forcibly unlocking the lock device D.
And the operating lever e of the handle E is connected to the dog d of the lock device D. Although not shown, the key cylinder F that can be locked and unlocked by a key is
It is attached to the lid B close to the handle E, and one end of the key cylinder F is exposed to the handle E.

-Problems to be Solved by the Invention- However, in the locking / unlocking operation device of this structure, since the locking device D is provided at the center portion in the width direction of the lid B, the lid B can be reliably locked on the instrument panel A. Although there are advantages, since the handle E and the key cylinder F are located far from the driver, when opening and closing the lid B or locking and unlocking the lid B,
The driver had to extend the upper body to the lid side for operation, which was not a convenient structure for the driver. With such a structure, the handle E
Since the position B is a position where the lid B is divided into two parts, the overall appearance design of the instrument panel A has an unchanged appearance, and it is difficult to obtain an appearance configuration having commercial value. When the lid B is locked by the key, the movement of the handle E is restricted by the key cylinder F. Therefore, if the handle E is forcibly operated without knowing the locked state, a failure may occur. It was

In view of the problems of the conventional glove box locking and unlocking operation device as described above, the object of the present invention is that it is convenient for the driver, rich in variability in appearance, and causes a failure due to an excessive operation of the steering wheel. To obtain the locking / unlocking operation device of the difficult glove box.

-Means for Solving the Problems-To achieve this object, the present invention provides a locking device arranged in the central portion in the width direction of an opening / closing body of a glove box and a steering wheel provided on the driver's side of the opening / closing body. In a glove box including a key cylinder of a key cylinder housing, the operation side end of an operation rod for operating the lock device is slidably supported by a mounting frame located near the handle, and fixed to the mounting frame. A follower arm having a linkage lever that is pivotally controlled by a key operation is fixed to the key lever, is located within the operating range of the operating lever of the handle when the key cylinder is unlocked, and is retracted outside the range of motion of the operating lever when locking. In addition, when the key cylinder is unlocked, the key cylinder is located within the range of motion at the operation side end and is retracted outside the range of motion of the operation side end at the time of locking. The present invention proposes a glove box locking / unlocking operation device in which an escape operation arm is provided on the link lever.

-Examples-Hereinafter, the details of the examples of the present invention will be described with reference to FIGS.

In FIG. 1 to FIG. 5, the instrument panel 1
The lid 2 as an opening / closing body of the glove box provided on one side has a lower portion hinged to the instrument panel 1, and the lock device 3 is attached to the central portion of the upper edge in the width direction. is there. The lock device 3 has a lock device body 4 which is fixed inside the lid 2, and a pawl 6 biased in a counterclockwise direction in FIG. It is supported so as to be rotatable around. This pawl 6 is a pair of locking claws 6a, 6 that can engage with a striker 8 arranged on the lower surface of the opening of the glove box body forming a part of the instrument panel 1.
b and an engaging portion 6c that is locked by a dog 9 provided in the lock device body 4. As shown in FIG. 1, the dog 9 is slidably supported by the lock device body 4 in a state of being biased toward the pawl 6 by a biasing spring 10.
The pawl 6 is locked at the locking position shown by the solid line by the tip locking claw 9a. Further, a driven-side end portion 12a of an operation rod 12 driven by a linkage lever 11 described later is connected to a base end portion 9b of the dog 9 protruding from the lock device body 4.

Further, an escutcheon portion 2a is formed on the upper right surface of the lid 2, and a handle 13 which can be manually operated is arranged on the escutcheon portion 2a. As can be understood from FIGS. 1 and 3, the handle 13 is rotatably supported at its upper part by a hinge shaft 15 of a mounting frame 14 incorporated in the lid 2, and the hinge shaft 15 is mounted on the hinge shaft 15. The fitting hinge spring 16 urges it in the counterclockwise direction in FIG.
The key cylinder housing 17 is attached to a part of the mounting frame 14.
Is integrally molded, and this key cylinder housing 17
A key cylinder 18 that is rotationally operated by a key (not shown) is supported by the key cylinder 18. One end of the key cylinder 18 is exposed on the surface of the lid 2. Then, as shown in FIG.
A key cylinder is provided at one end of the key cylinder housing 17.
A linkage lever 11 that is forcibly rotated by 18 is supported. The linkage lever 11 has a driven arm 11a, and an operation lever 13a integrally formed on the upper portion of the handle 13 at a right angle faces the movement locus range of the tip of the driven arm 11a. The link lever 11 is an elastic claw integrally formed with the base thereof.
11b, and the tip of this elastic claw 11b is in contact with the peripheral surface of the key cylinder housing 17, and the key cylinder housing 17 is provided on the peripheral surface of the key cylinder housing 17 corresponding to the moving range of the elastic claw 11b. The protrusion 19 for preventing easy movement is integrally molded. Therefore, because of the presence of the projection 19, the linkage lever 11 can freely rotate in the clockwise direction in FIG. 3 only within a certain range, but the key cylinder 18 forces the linkage lever 11 to rotate in the clockwise direction. Then, the elastic claw 11b gets over the protrusion 19 and the linkage lever 11b
Is placed in the locking position indicated by the phantom line, and the driven arm 11a of the link lever 11 retracts out of the range of motion of the operating lever 13a of the handle 13.

On the other hand, the mounting frame 14 is formed with a guide groove 21 for guiding the slider 20 fixed to the operation side end 12b of the operation rod 12, and as described above, the urging spring 10 of the dog 9 urges the slider 20 in one direction. The operation side end portion 12b of the operated operation rod 12 is projected within the range of motion of the operation arm 11c integrally formed with the linkage lever 11. Therefore, handle the driver's hand
When 13 is operated, the driven arm 11a of the linkage lever 11 is pressed downward by the operation lever 13a of the handle 13,
The linkage lever 11 is rotated counterclockwise in FIG. 3 and the slider 20 is moved leftward by the operation arm 11c of the linkage lever 11, the dog 9 is retracted from the pawl 6 by the operation rod 12, and the pawl 6 is moved. The lid 2 is opened by rotating around the pole shaft 7.

Since the locking / unlocking operation device for the glove box according to the illustrated embodiment has the above-described structure, in the assembled state of the link lever 11 with respect to the mounting frame 14, the presence of the protrusion 19 causes the link lever 11 to move clockwise in FIG. Such a rotational movement is suppressed, and the counterclockwise rotational movement of the linkage lever 11 is restricted by the slider 20. Therefore, when the handle 13 is assembled to the mounting frame 14, the driven arm 11a of the linkage lever 11 moves as shown by the phantom line in FIG. 3, and the handle 13 is disabled due to an assembly error. It can be prevented.

Further, since the lid 2 of the glove box after the assembly is completed is locked at the center portion in the width direction by the lock device 3, it is possible to obtain a stable locked state against vibration of the vehicle body and the like, and the handle 13 and the key cylinder 18 are provided. Is arranged on one side of the lid 2 that is close to the driver side, so that the driver can open and close the lid 2 simply by reaching. That is, to open the lid 2, pull the handle 13 by pulling it by hand.
The operating lever 13a rotates the linkage lever 11 clockwise in FIG. 1 and pulls the operating rod 12 rightward in FIG. 1, so that the dog 9 is pushed against the force of the biasing spring 10. 6
The striker 8 is pushed out by the force of the return spring 5 of the pawl 6, and the lid 2 is opened. On the contrary, when the lid 2 is closed, if the lid 2 is strongly pressed toward the instrument panel 1, the striker 8 intrudes to rotate the pawl 6 in the clockwise direction in FIG. The tip claw of the dog 9 falls into the engaging portion 6c of 6, the dog 9 prevents the pawl 6 from returning, and the lid 2 is locked to the instrument panel 1.

Further, in order to prohibit the opening of the lid 2 by the handle 13, the key cylinder 18 is operated by the key to move the linkage lever.
11 may be located at the position indicated by the phantom line in FIG. That is, when the key cylinder 18 forcibly moves the link lever 11 from the position shown by the solid line in FIG. 3 to the position shown by the virtual line, the elastic claw 11b of the link lever 11 gets over the projection 19 during this time, so Can feel to know that the key cylinder 18 is in the locking position. In other words, at this position of the linkage lever 11, the operation arm 11c of the linkage lever 11 is retracted outside the movement locus of the operation lever 13a of the handle 13. Therefore, even if the handle 13 is operated by hand, the locked state of the lid 2 is not canceled only by freely rotating the handle 13, so that the handle 13 can be prevented from being forcibly operated. Of course, even when the linkage lever 11 is returned to the position shown by the solid line in FIG. 3 by the key cylinder 18 and the lid 2 is unlocked, the elastic claw 11b of the linkage lever 11 rides over the protrusion 19, so the operator , It is possible to clearly know the unlocked state of the lid 2 by touch.

As can be seen from FIG. 2, the glove box according to the illustrated embodiment has a handle 13 and a key cylinder 18 which are arranged closer to one side of the lid 2, so that the glove box has a variety of appearances and is highly marketable. .

In addition, in the above-mentioned embodiment, although the example in which the present invention is applied to the lid type glove box has been described, it is needless to say that the present invention is also applicable to a so-called bucket type glove box.

-Effects of the Invention-As is apparent from the above description, according to the present invention, it is possible to obtain a locking / unlocking operation device for a glove box that has a wide variety of appearances and is easy for a driver to operate. Further, according to the present invention, it is possible to improve durability without exerting an unreasonable force on the operation lever and the locking device when locking.
