For this reason, the conventional opening / closing lid is designed to be opened and closed by rotating about one axis as described above, so that a rotatable gap is required between the lid and the instrument panel. However, these gaps appear as gaps when the opening / closing lid is fully closed, which impairs the beauty of the interior of the vehicle, and when dust or the like accumulates in the gaps, cleaning becomes difficult, which is not preferable in terms of hygiene. In addition, when the opening / closing lid is fully closed and fully opened, there is a problem that a rattling sound is generated by transmission of vibration from the body of the automobile. Furthermore, since the openable lid is protruded from the front of the instrument panel, there is a problem that the lid becomes dangerous when a collision occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide no gap between the open / close lid and the instrument panel when fully closed, and to fully close and fully open the open / close lid. It is an object of the present invention to provide an opening / closing mechanism for a storage box for a vehicle, which can obtain an open state of an opening / closing lid that does not sometimes generate rattling noise and does not project from an instrument panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on illustrated embodiments. FIG. 1 shows a storage box 2 to which an opening / closing mechanism 1 according to an embodiment of the present invention is attached. The storage box 2 is formed in the instrument panel 3 as a recess opening toward the occupant, and the opening is closed by an opening / closing lid 4 that is opened / closed by the opening / closing mechanism 1.

The opening / closing mechanism 1 is mounted on the left and right sides of the opening / closing lid 4 so as to be suspended between the opening / closing lid 4 and the side wall 2a of the storage box 2, and guides the opening / closing of the opening / closing lid 4. The opening and closing mechanism 1 includes a first link member 5 and a second link member 6 as shown in FIGS. 2 and 3.

The first link member 5 has an arm portion 5d bent in a substantially U-shape. One end 5a is pivotally supported by a bracket 9 fixed to the side wall 2a of the storage box 2, and the opening / closing lid 4 is provided.
The other end 5b is pivotally attached to a bracket 10 fixed to the bracket 10. As shown in FIG. 2, a groove 5c is formed in the arm 5d of the first link member 5, and the groove 5c is formed in the arm 5d.
Is formed with a through hole 5f (see FIG. 6). The first link member 5 is attached to the left and right sides of the opening / closing lid 4 with a similar attachment structure.

The second link member 6 has an arm portion 6c bent in a substantially rectangular shape, and the other end 6b is extended to form a connecting rod 7. The other second link member 6 is similarly formed at the other end of the connecting rod 7. Protrusions 6d, 6d are formed on both side surfaces of the arm 6c (see FIG. 5). Of the convex portions 6d, 6d, the convex portion 6d formed on the surface side (on the paper surface of FIG. 2) of the arm portion 6c fits into the through hole 5f of the first link member 5 when the cover 4 is fully opened. Yes (see FIG. 6), convex portion 6 formed on the opposite back side
d is a recess 9 formed in the bracket 9 when the cover 4 is fully closed.
a (see FIG. 5). One end 6a of the second link member 6 is pivotally supported by a bracket 9, and a connecting rod 7 is rotatably supported and mounted on a bearing 10a of the bracket 10. The second link member 6 is mounted on the left and right sides of the opening / closing lid 4 with a similar mounting structure.

The opening / closing mechanism 1 configured as described above operates as follows. FIG. 4 shows the open / close lid 4 in a fully opened state. In this state, the groove 5c of the first link member 5 abuts against the arm 6c of the second link member 6, and the projection 6d of the second link member 6 is inserted into the through hole 5f of the first link member 5. (See FIG. 6), further opening operation of the opening / closing lid 4 is prevented. At this time, the opening / closing lid 4 is supported at a position separated from the instrument panel 3 by the first link member 5 and the second link member 6. At this time, the opening / closing lid 4 is in a fully opened state with no play due to the concave / convex fitting of the through hole 5f and the convex portion 6d.

When the opening / closing lid 4 is closed in the direction A from the fully opened state, the fitting of the through-hole 5f and the projection 6d is released, and the opening / closing lid 4 is connected to the first link member 5 and the second link member. 6 to rotate while asymptotically approaching the opening of the storage box 2. Thus, the opening / closing lid 4 reaches the fully closed state shown in FIG. 2, and the other convex portion 6d of the second link member 6
Fits into the concave portion 9a of the bracket 9 (see FIG. 5), and the handle 13 engages with the lock claw 12 to maintain this state. At this time, the opening / closing lid 4 is in a fully closed state with no backlash due to the concave and convex fitting of the concave portion 9a and the convex portion 6d.

The opening operation is performed by rotating the lock claw 12 in the direction B to release the engagement with the handle 13 as shown in FIG. When the opening / closing lid 4 is loaded in the opening direction after the release, the concave / convex fitting between the concave portion 9a and the convex portion 6d is first released, and the opening / closing lid 4 rotates in the opening direction. This rotation is guided by the first link member 5 and the second link member 6, and the opening / closing lid 4 rotates while gradually moving away from the opening of the storage box 2.

As described above, according to the opening / closing mechanism 1, the opening / closing lid 4 is opened or closed while ascending or approaching the opening of the storage box 2. Even if it is formed to a considerable size,
The opening / closing lid 4 does not interfere with the instrument panel 3 at the time of opening / closing, and a smooth opening / closing operation can be obtained. Therefore, a fully closed state with no gap between the opening / closing lid 4 and the opening of the storage box 2 is obtained.

The present invention is not limited to the above-described embodiment, but may be modified as follows without departing from the spirit of the present invention. That is, the through hole 5f formed in the first link member 5 may be a simple concave portion, or a convex portion may be formed in the first link member 5 and the concave portion in which the convex portion fits in the second link member 6 may be formed. It may be formed. At this time, the concave portion formed in the second link member 6 may be formed by a through hole, and the bracket 9 may be formed with a convex portion that fits into the concave portion. Alternatively, instead of the bracket 9, the side wall 2a of the storage box may be used as it is, and the recess 9a may be formed in the side wall 2a.
