Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a glove box mounting lock device formed in an automobile instrument panel or the like.

The lid of a conventional glove box has a knob 2 at the center of the upper side of the lid 1, as shown in Figure 1.
A single claw 3 that can be operated by the box 4 is provided, and locking is performed by hooking this claw 3 onto a locking piece 5 provided on the upper edge of the opening of the box 4 on the instrument panel side.

For this reason, the position of the lid 1 with respect to the box 4 is regulated at the center, which tends to make the compatibility between the lid 1 and the box 4 especially at the left and right ends of the lid uncertain, and it is difficult to adjust this alignment. .

In addition, in the lid structure described above, play is likely to occur at the left and right parts of the lid, so bumper rubbers 6 are installed at the left and right ends of the box 4.
6 is provided, and a reaction force P is applied to both ends of the lid 1 when the lid is locked. However, in conventional lids in which resin or the like is used as the material, the reaction force P acts as shown in Fig. 1A. The left and right ends tend to be thermally deformed, such as curving outward, and to prevent this, expensive materials with high rigidity and heat resistance must be used.

Furthermore, since the lock part must be provided at the center of the lid 1, the installation position of the knob 2 is limited to the center of the lid 1, that is, a position that is difficult for the driver to reach, making it difficult for the driver to open and close the lid 1. It's inconvenient.

Furthermore, in order to improve the engagement between the pawl 3 and the locking piece 5, it is necessary to make the locking piece particularly large, and the space occupied by the locking piece becomes large, making effective use of the inside of the box 4. It makes the space narrower.

The present invention has been developed in view of the above, and its purpose is to improve the compatibility between the lid and box at the left and right ends by providing separate locking mechanisms at the left and right ends of the lid and the box, respectively. It is an object of the present invention to provide a lid locking device which can prevent thermal deformation of a lid, improve warp engagement, and reduce the volume of a locking mechanism occupying inside a box, thereby making effective use of the inside of the box.

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 2 is an exploded perspective view of the device of the present invention, and FIG. 3 is a plan view thereof. The lower end of the lid is connected to hinges 11, 11, and rotates in the vertical direction to open and close the opening of the glove box 10.

Approximately L-shaped locking pieces 12 and 13 are attached to the left and right ends of the opening of the glove box 10, respectively.
13a is facing inward.

The lid 20 is integrally attached to an inner plate 21 curved to match the opening shape of the box 10 and to the outside of this inner plate 21, and defines a predetermined internal space between the lid 20 and the inner plate 21. It consists of an outer plate 22.

The portion facing the locking pieces 12 and 13 is configured so that the inner plate 21 and the outer plate 22 form parallel planes, and the area defined by the parallel inner plate 21 and outer plate 22 is The claw body of the locking device is housed within the internal space.

That is, a pin support shaft 23 is provided at the inner side portions of the left and right ends of the inner plate 21, in other words, at portions facing each of the locking pieces 12,13.
24 and stopper 25. 26 will be erected.

A spring 27 is inserted into one (left side of the figure) pin support shaft 23, and a pawl body 28A having an arc-shaped locking portion 28a on the outside and a hook 28b on the inside is loosely inserted, and the snap ring 29 is used to remove the spring 27. I'm trying to stop it.

The claw body 28A is biased to rotate clockwise around the pin support shaft 23 in a plane parallel to the inner plate 21 and the outer plate 22 by the spring 27 suspended between the stopper 25 and the spring 27. When the lid is rotatably locked by the stopper 25, the tip of the locking portion 28a protrudes from the right end surface of the lid.

The other pin support shaft 24 (on the right side of the figure) has a claw body 30 having a substantially arc-shaped locking part 30a on the outside, a knob fitting part 30b on the inside, and a hook 30C protruding on the opposite side.
B is loosely inserted, and a snap ring 31 is used to prevent it from coming off.

This claw body 30B is connected to the hook 30C and the claw body 28A.
The steel wire link 32 hooked between the hook 28 b
As a result, the urging force of the pawl carrier 28A is transmitted, and the stopper 26 is urged to rotate around the pin support shaft 24 in a plane parallel to the inner plate 21 and the outer plate 22 in a counterclockwise direction.
When the lid is rotationally locked, the tip of the locking portion 30a protrudes from the left end surface of the lid.

An operating knob 34 having a protruding pin portion 34a on the lower surface thereof is fitted into the knob fitting portion 30b through a long hole 33 formed in the left-right direction near the right end of the outer plate 22, and the operating knob 34 has a protruding pin portion 34a on the lower surface thereof. is inserted into the elongated hole 35 of the knob fitting part 30b.

Needless to say, the operation knob 34 is prevented from falling off by a locking means (not shown).

According to the above-mentioned explanation and the locking device, when the lid 20 is closed as shown in FIG. 7') Due to the biasing force in the a2 direction, the claw body 28A engages with the short piece part 12a of the locking piece 12, and the claw body 30B engages with the short piece part 13a of the locking piece 13, and each locking part 28a , 30a protrude in the lid opening direction (direction of arrow A in the figure), so that the locking portion 2
8a, 30a cannot get over the short pieces 12a, 13a, and therefore the rotation of the lid 20 in the direction of arrow A in the figure, that is, the opening rotation is locked.

When the operation knob 34 is moved from side to side in this state, the protruding pin portion 34a forcibly rotates the claw body 30B in the direction b2 in the same figure, releasing the locking of the locking portion 30a, while simultaneously rotating the claw body 30B. This rotation rotates the pawl body 28A in the direction b1 in the figure through the link 32, and releases the locking of the locking portion 28a.

This allows the lid 20 to be opened. When closing the lid, strongly rotate the lid 20 to close the lid, and the claw body 2
8A, each of the locking portions 28a, 30a of the claw body 30B is in a protruding state and abuts on the short piece portions 12a, 13a, but since each of the locking portions 28a, 30a is an arcuate surface, due to the corresponding contact, the locking portions 28a, 30a in the same figure b1 , b are rotated in the two directions, respectively, and the short pieces 12 a,
13a, and once it has been overcome, it automatically enters the locked state as described above.

Note that a string with high tensile strength may be used as the link instead of the steel wire in the above embodiment, which is effective in reducing costs and preventing abnormal noise caused by contact with the claw body.

In summary, according to the present invention, since the lid is locked by providing a locking portion consisting of a locking piece and a pawl at both the left and right ends of the lid, the compatibility between the box and the lid is particularly improved at the left and right ends of the lid. Moreover, even if a problem occurs between the two, the left and right positions can be adjusted independently.

In addition, since the lid is locked at the left and right ends, there is little play, and the bumper rubber can be omitted, preventing thermal deformation of the lid.

In addition, each pawl body is biased to rotate in a direction in which the locking portion protrudes to the outside of the lid, and when the lid is rotated to close, it can rotate against the biasing force due to contact with the locking piece. With this structure, when the lid is closed, it is automatically locked.

In addition, since the rotation plane of the claw body is set to be parallel to the inner and outer plates of the lid, the lid can be made thinner and the compatibility between the box and the lid is improved, allowing the lid to move closer to the box side. The provided locking piece can be made smaller and the space it occupies can be reduced, so that the effective use space of the box can be increased.

Furthermore, since both claw bodies are linked and the operating knob is provided on one of the claw bodies, it is easier to reach the operating knob, and if the operating knob is installed on the side near the driver's seat, It has many practical effects, such as making it easier to open and close the lid.
