Description

[Detailed explanation of the idea] The present invention relates to a lidlock device.

2. Description of the Related Art Automobiles, general houses, factories, etc. are equipped with various types of storage compartments depending on their uses, and representative examples of such storage compartments in automobiles include glove boxes and console boxes. Such storage compartments are provided with a lid for closing the storage compartment and a lid locking device for locking the lid when the storage compartment is closed. However, conventional lid lock devices usually consist of a lock body, a pin that supports the lock body, a holder that holds the pin, a spring that provides rotational behavior to the lock body, etc., and has a large number of parts. For this reason, the number of man-hours required to assemble the lid lock device to the lid increases, which not only requires a great deal of time but also increases the cost of the device.

In addition, a lid lock device has been proposed that reduces the number of parts and is composed of only a lock body and a spring, but in the configuration related to the conventional proposal, a pivot pin protruding from the lock body is fitted into a hole formed in the lid. By doing so, the lock body is supported on the lid, which complicates the shape of the lid and increases its manufacturing cost. Furthermore, there is also the disadvantage that the work of assembling the lock body to the lid is complicated. Furthermore, in the lid lock device proposed in the prior art, if the lock body is strongly pulled toward the user, there is a risk that the pivot pin may come off from the hole in the lid.

This invention was made based on the above recognition,
The purpose of this is to reduce the number of parts, simplify the structure and assembly work, reduce manufacturing costs, and even when the lock body is pulled strongly.
This is to provide a lid lock device that does not become detached from the lid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention as a lid lock device for a glove box attached to an automobile will be described in detail below with reference to the drawings.

1 to 3, reference numeral 1 indicates an instrument panel (hereinafter referred to as an instrument panel) provided at the front of a driver's cab of an automobile, and a glove box 2 is attached to this instrument panel 1. As shown in FIG. In this example, the box 2 is integrally molded with the instrument panel 1, and objects (not shown) can be stored in the box 2.

The opening of the glove box 2 is closed by a lid 3 which can be opened and closed, and a mounting portion 4 attached to the lower part of the lid is screwed to the glove box side. A thin hinge part 5 with a reduced wall thickness is formed between the lid 3 and the mounting part 4, and the lid 3 moves around this thin hinge part 5 in the closed position shown by a solid line in FIG. 3 and in the closed position shown by a chain line in FIG. and can be rotated between open positions.

The lid may be composed of two panels,
The lid can also be pivotally attached to the glove box side by a suitable hinge other than the thin-walled hinge portion. Alternatively, it is also possible to mold the lid integrally with the glove box via a thin hinge.

The lid 3 brought into the closed position is locked by a lid locking device 6 according to the invention. The lid lock device 6 has a lock body 7 and a leaf spring 8, as shown clearly in FIGS. 3 to 8. The lock body 7 includes a handle part (knob) 9 used when operating the lock body, an arm part 10 protruding from the handle part 9, a hook part 11 formed at the tip of the arm part, and a hook part 11 protruding from both sides of the arm part. It has a pair of guide pins 12 and a pair of rotation center parts 13 arranged closer to the handle part 9 than these pins 12, and these are integrally molded in advance. The rotation center portion 13 is a portion around which the lock body 7 rotates within a predetermined angular range, as will be described later.The illustrated rotation center portion 13 is integrally connected to the handle portion 9 and has a substantially semicircular shape. It has a cross-sectional shape of . Of course, the rotation center may be placed apart from the handle portion 9, provided that it can function as the rotation center.

On the other hand, a recess 15 is formed in the lid 3 from the passenger compartment 14 side toward the glove box side, and when this recess 15 is viewed from the glove box 2 side, it is shown in FIGS. 4 and 5. It has a prominent box-like shape. In addition, a through hole 16 is formed in the lid portion constituting the bottom of the recess 15, and this through hole 16 is connected to the wide portion 1 at the bottom of the through hole 16.
6b, and a narrow portion 16a that communicates with this and is laterally narrower than the wide portion 16b. In addition, a pair of receiving surfaces 17 are formed in the recessed portion 15, as shown in FIGS. 6 and 8, which are located on both sides of the narrow portion 16a of the through hole 16.
It is formed on the front side of the lid 2, that is, on the surface facing the passenger compartment, and has a shape corresponding to the rotation center portion 13 described above.

The arm portion 10 of the lock body 7 is passed through the narrow portion 16a of the through hole 16 from the front side (interior side) of the lid 3, and the rotation center portion 13 is rotatably fitted into the receiving surface 17. Therefore, the lock body 7 moves around the axis X of the rotation center 13 as shown by the arrow A (FIG. 3).
It is supported on the lid 3 so as to be rotatable in the direction. The handle portion 9 is located in the recess 15, and an occupant inside the vehicle can reach the handle portion and place his or her fingers on it.

In addition, as shown in FIGS. 3 to 5, the through hole 1
A pair of guide surfaces 18 are formed on both sides of the narrow portion 16a of the lock body 7, and these guide surfaces 18 align the rotation axis of the lock body 7, that is, the axis X of the rotation center portion 13, as shown clearly in FIG. It is formed along a circular arc B at the center. The guide surface 18 is formed on the back surface of the lid (the surface opposite to the vehicle compartment),
A guide pin 12 protruding from an arm portion 11 of the lock body 7 is in contact with a guide surface 18.

One end of the leaf spring 8 is fixed to the lid 3 by a screw 19, and the free end of the spring is pressed against the lower surface of the arm portion 10. Therefore, arm part 1
0 is given a clockwise rotation behavior in FIG. 3, and therefore, when the lid 3 occupies the closed position shown by the solid line in FIG. Striker 20 attached to glove box 2 (see also Figure 2)
While protruding into the locking hole 21, it is securely locked to the edge 22 of the locking hole 21. The lid 3 is thus locked in the closed state, and the inconvenience of opening it inadvertently is prevented. As the striker, any suitable striker other than the one shown may be used, such as a striker made of a bar fixed to a lid.

To open the lid 3, touch the handle 9 with your finger 23.
(Figure 3) and pull it in the direction of arrow C. As a result, as shown in FIG. 7, the lock body 7 rotates counterclockwise in FIG. 7 about the axis X of the rotation center portion 13 against the action of the leaf spring 8, and the hook portion 11 is rotated counterclockwise in FIG. It comes off from the edge 22 of the locking hole 21. At this time, the guide pin 12 rotates around the axis X of the rotation center 13 while slidingly contacting the guide surface 18, so that the lock body 7 rotates smoothly without coming off from the lid 3 or rattling. can move. Even if the handle part 9 is accidentally pulled strongly toward the front (interior side), the lock body 7 will not come off from the lid 3. In this way, the lid 3 is released from its locked state and can thus be pulled in the direction of arrow D (FIG. 3) to bring it into the open position shown in phantom.

To close the lid 3, it is only necessary to rotate it from the open position shown in dashed lines to the closed position shown in solid lines in FIG. At that time, when the hook part 11 enters the locking hole 21, the back surface of the tip hook part 11 is connected to the edge 22.
After the lock body 7 rotates slightly counterclockwise in FIG. 3, the hook part 1
1 engages with the edge 22 of the locking hole 21.

The operation of the above-mentioned lid lock device 6 is the same as that of the conventional device, but its main components are only the lock body 7 and the leaf spring 8, and an independent pin and a holder to support it are unnecessary, and the number of parts is reduced. can be reduced. Further, since the lock body 7 is assembled to the lid 3 by fitting the rotation center portion 13 into the receiving surface 17 of the lid 3, the shape of the lid 3 can be simplified and its manufacturing cost can be reduced. . Moreover, the assembly work of each part is easy, and an example thereof is as follows.

First, when assembling the lock body 7 from the front side of the lid 3, the lock body 7 is brought close to the recess 15, and the arm portion 10 and the pair of guide pins 12 are inserted into the through hole 16.
pass through the wide part 16b of. Wide portion 16 of through hole 16
Since b is formed to have a wide width, the guide pin 12 protruding from the arm portion 10 can also pass through the through hole 16 without any hindrance. Next, the lock body 7 is slightly lifted to fit the rotation center portion 13 into the receiving surface 17, and the guide pin 12 is brought into contact with the guide surface 18.

On the other hand, one end of the leaf spring 8 is screwed to the lid 3, and the spring 18 is brought into pressure contact with the lower surface of the arm portion 10 that has already been fitted into the through hole 16.

It goes without saying that the present invention is applicable not only to lids for glove boxes, but also to lids for other suitable storage spaces.

As can be seen from the above explanation, the lid lock device according to the present invention has a small number of component parts,
In addition, the lock body is provided with a rotation center with an approximately semicircular cross-sectional shape, and this is fitted into the receiving surface of the lid to support the lock body on the lid, which simplifies the shape of the lid and reduces manufacturing costs. Can be reduced. Furthermore, since the guide pin provided on the lock body is brought into contact with the guide surface provided on the lid, it is possible to prevent the lock body from coming off the lid during normal use. Moreover, the lock body can be assembled to the lid very easily.
