DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glove box which can be opened and closed at an opening of an instrument panel for a vehicle, and more particularly to a glove box having a box body, an inner door panel and an outer door panel. It is about structure.

[0002]

2. Description of the Related Art Generally, a storage means called a glove box is provided at a position corresponding to a front passenger seat of an instrument panel in a vehicle cabin. By the way, if there is any acceleration fluctuation in the automobile, the knee of the occupant sitting in the passenger seat may hit the glove box. The following two measures can be considered to absorb the impact in such a case. That is, one is to absorb the impact force by deforming the door panel itself of the glove box (Japanese Utility Model Laid-Open No. 4-109650). Another one is to provide a shock absorbing means inside the instrument panel so as not to deform the glove box door panel itself as much as possible (JP-A-4-63745). The deformation of the shock absorbing means allows the entire glove box to move.

[0003] The latter example will be described in more detail.
As shown in FIG. 9, for example, the glove box 51 includes a box body 52 and a door 53. The door 53 is made of a resin inner door panel 54 and an outer door panel 5.
5 and a reinforcing insert 56 made of iron plate is provided in the inside thereof. Further, inside the instrument panel 57, an impact absorbing means 58 is provided, one end of which is separately fixed and the other end of which is in contact with the glove box 51.

[0004] When an impact is generated in such a structure, the glove box 51 itself is not deformed due to the presence of the reinforcing insert 56, and the stress is transmitted to the shock absorbing means 58. When the shock absorbing means 58 is deformed, the entire glove box 51 moves forward (to the left in FIG. 9), and the shock force is absorbed. According to such a technique, since the door 53 has a predetermined rigidity and is not easily deformed, the door panels 54 and 55, especially the outer door panel 55, are hardly deformed.

[0005]

However, in the latter prior art, since the reinforcing insert 56 made of an iron plate is provided, the weight is significantly increased. For this reason, a load is applied to the hinge portion (around the rotation axis) that allows opening and closing of the glove box 51, and the strength of the portion must be set strong. Also,
Since the weight of the entire glove box 51 increases,
Opening and closing operations were sometimes difficult.

Further, the number of parts has increased, which has led to an increase in cost and a deterioration in assembling workability. The present invention has been made to solve the above problems, and an object of the present invention is to reduce the weight, reduce the cost, and improve the assembling workability without reducing the rigidity. It is to provide a glove box structure.

And a resin outer door panel attached to the outer side of the inner door panel, wherein a glove box structure is provided so as to be openable and closable at an opening of the vehicle instrument panel, wherein the inner door panel and the least one of the outer door panel, provided integrally protrudes a reinforcing rib for reinforcing the entire two panels towards the other door panel, and, prior to
A gap is provided between the reinforcing rib and the other door panel.
That provided that the gist thereof.

Further, in the invention according to claim 2,
In the glove box structure according to claim 1, the gist is that the reinforcing ribs are formed in a lattice shape.

Further, in the invention according to claim 3, in the glove box structure according to claim 1,
The gist is that the reinforcing ribs are composed of a plurality of ribs and are formed so as to extend in parallel with each other.

According to a fourth aspect of the present invention, in the glove box structure according to the first or third aspect , the tip of the reinforcing rib is connected to the other door.
The gist is that it is housed in a recess formed in the panel .

[0011]

[0012]

[0013]

According to the first aspect of the present invention, the box body, the inner door panel provided integrally with or joined to the box body, and the outer door panel attached to the outer side of the inner door panel. The glove box configured as described above is disposed in an opening of the vehicle instrument panel and can be opened and closed. And various goods can be accommodated in a box main body.

In the present invention, at least one of the inner door panel and the outer door panel is integrally provided with a reinforcing rib protruding toward the other door panel. For this reason, the rigidity of the inner door panel and the outer door panel is ensured by the ribs, and the entire panels are reinforced. Further, since the ribs are made of resin similarly to the inner door panel or the outer door panel, the presence of the ribs does not significantly increase the weight. In addition, reinforcing ribs
