Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a glove box installed in front of a passenger seat in a vehicle interior, and particularly relates to a lock structure for activating and releasing the lock.

(Prior Art) In the cabin of an automobile, a glove box for storing road maps and other small items is usually provided in front of the passenger seat. This glove box is provided with a lid that can be opened and closed, but is often provided with a locking mechanism to prevent theft when the lid is closed. This locking mechanism could be a mechanism that prevents the knob for opening and closing the lid from operating, but glove boxes, lids, and knobs are mostly made of plastic to reduce the weight of the car, so it is not often used. Since it is not strong enough, if the knob is not allowed to move at all when the lock is locked, there is a risk that the occupant may pull on the knob and damage the knob.

For this reason, it has been considered to create a structure in which the lid can be operated when the lid is locked, but the knob simply clicks blankly and the lid cannot be opened. For example, as disclosed in Japanese Utility Model Application No. 58-62753, a lock bar that slides up and down within the lid body engages and disengages from the striker, and a horizontal elongated hole in the lock bar is used. The locking plate placed on the lock bar is moved up and down in accordance with the rotation of the knob, and the locking bar is slid up and down.On the other hand, the locking plate is slid by a key cylinder lock for locking, and when the knob is locked, the locking plate is moved up and down according to the rotation of the knob. There is a device in which the locking plate is disengaged from the locking plate so that the locking plate does not move regardless of the rotation of the knob, allowing the knob to be driven blankly.

However, in the above case, a structure is required to hold the lock bar slidably up and down inside the lid body inside the knob, and since this lock bar holding part is relatively large, it is necessary to have a structure in which the lock bar is held inside the glove box or inside the knob. There is a problem of protrusion into the inner space. There is a limit to the size of the glove box itself due to vehicle space considerations, and it is desirable to keep the pressure on the internal space of the glove box due to the lock structure to the minimum necessary, so it is preferable for the lock bar holding portion to protrude into the inside of the glove box. do not have. Furthermore, if the lock bar holding portion protrudes into the space inside the knob, there is a problem in that the space in which the occupant can put his/her hand in to operate the knob becomes narrow, making it difficult to operate the knob. For this purpose, the knob may be extended downward, but this is undesirable in terms of appearance and strength.

(Purpose of the invention) The present invention has been made in view of the above circumstances, and an object thereof is to provide a glove box lock structure that is as compact and simple in structure as possible.

(Structure of the invention) The lock structure of the invention includes a hook member having an engaging part that engages with a striker on the glove box body side at one end, and a bifurcated leg part formed at the other end of the hook member, and both base ends of this leg part. is swingably attached to the lid, and the engaging portion is moved upward by this swinging to engage with the striker, and a lid opening/closing knob member is swingably attached to the lid, and is integrated with this knob member. A claw formed in the above-mentioned shape is positioned corresponding to the space between the bifurcated legs, and the other end of the connecting member, the other end of which is connected to the key cylinder lock attached to the lid on the side of the hook member, is connected to the leg. When the key cylinder lock is unlocked, the other end of the connecting member is located in the recess and below the pawl, and the knob member is swung to open the lid. When the key cylinder lock is locked, the claw portion that moves downward comes into contact with the other end of the connecting member and pushes the hook member, causing the engaging portion to move downward. When the key cylinder lock is locked, the connecting member is moved downward. The hook member is characterized by being slid on the concave portion so that the other end moves to a position away from the swinging locus of the claw portion, and the hook member does not swing even if the knob member swings. be.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the lock structure of the present invention, showing the structure with the lid closed and the lock released. In this figure, the glove box main body and the lid are shown with the lock structure of the present invention attached to the glove box main body and the lid.

The lid opening/closing knob 1 is swingably attached to the lid via a shaft 4 whose upper ends 1a and 1b are attached to the lid. The knob 1 is operated by an occupant pulling the lower end 1c toward him (in the direction of arrow B), and is normally held in the state shown in the figure by a torsion spring or the like. knob 1
A claw portion 2 projecting obliquely upward is integrally formed at the center of the upper end, and this claw portion 2 is adapted to swing together with the knob 1. On the other hand, hook 3
has an engaging portion that engages with the striker 10 fixed to the glove box body at one end, and bifurcated leg portions 3b, 3b at the other end. This leg portion 3b,
The proximal ends 3d, 3d of 3b are swingably attached to a shaft 4 to which the knob 1 is swingably attached, and the hook 3 is swingably attached to the lid via the shaft 4. There is. Further, recesses 3c, 3c extending laterally are formed on the upper surfaces of the legs 3b, 3b, and the other end 5a of the connecting member 5 is placed on the recesses 3c, 3c. Note that the claw portion 2 is located above the space between the leg portions 3b, 3b.

Further, on the right side of the knob 1, a key cylinder lock 6 for locking is fixed to a lid, and the key cylinder lock 6 is connected to one end 5b of the connecting member 5 at the rear surface of the key cylinder lock 6. FIG. 2 shows this connected state when viewed from the direction of arrow A. As can be seen from this figure, the protrusion 6c on the rear surface of the rotating part 6b into which the key is inserted and turned, and one end of the connecting member 5. 5b is fitted into the elongated hole 5c, and the connecting member 5 is slid by a distance "E" in the direction of arrow D as the protrusion 6c moves due to the rotation of the rotating part 6b. .

The operation of the lock structure constructed as above will be explained below.

First, when the lock is released, that is, as shown in FIG. 1, the other end 5a of the connecting member 5 is placed on the recesses 3c, straddling the legs 3b, 3b. For this reason, the lower end 1c of the knob 1 is pulled forward and arrow B
When the claw portion 2 swings in the direction, the claw portion 2 moves downward and connects the connecting member 5.
It comes into contact with the other end 5a and pushes the hook 3 downward via this connecting member 5. For this reason, hook 3
swings around base ends 3d, 3d attached to the shaft 4, and the engaging portion 3a moves downward to disengage from the striker 10, allowing the lid to be opened. Note that since the hook 3 is biased upward by a torsion spring or the like, the engaging portion 3a engages with the striker 10 due to the biasing force even if the knob 1 is not operated when the lid is closed. I'm starting to do that.

Next, to lock the lock, press the key cylinder lock 6.
The key is inserted into the key opening 6a to rotate the rotating portion 6b, thereby causing the connecting member 5 to slide to the right in FIG. 1 via the projection 6c. Therefore, the other end 5a of the connecting member 5, which was placed on the recess across the legs 3b, 3b of the hook 3, slides to the right and moves to the right from the space between the legs 3b, 3b. position, and deviates from the swing locus of the claw portion 2 located above this space.

In this state, even if the knob 1 is operated to move the claw part 2 downward, the claw part 2 only moves within the space between the legs 3b, 3b, and does not give any movement to the hook 3. That is, the knob 1 is in an idle state, and the engagement of the hook 3 is maintained as it is.

(Effects of the invention) As explained above, according to the invention, the hook member for engaging with the striker to close and hold the lid is swingable with respect to the lid, and the hook is attached to the lid through the claw part. The lid opening/closing knob member is swung to engage and disengage from the striker in response to the swiveling of the lid opening/closing knob member. Since the lock is operated and released by intermittent vibration transmission, the lock structure can be made compact and simple, and the pressure on the internal space of the glove box due to the lock structure can be reduced. I can do it. Furthermore, there is sufficient space inside the knob to put your hand in to operate the knob, making it easy to operate the knob. In addition, since the knob is pressed dry when the lock is locked, it is possible to prevent the knob from being forcibly pulled and damaged.
In addition, since the legs of the hook member are bifurcated and the load from the knob is received between the two forks, the load is transmitted within the same rotational plane, and the rotation support shaft of the hook member and knob member is No bending moment is added and load transmission is improved.
