DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a damper device used for opening a glove box of a vehicle.

[0002]

2. Description of the Related Art A conventional damper device used when opening and closing a glove box of a vehicle is disclosed in Japanese Patent Publication No. 5-6839.
As exemplified in Japanese Unexamined Patent Application Publication No. 1 (1999) -2000, a lower end of a glove box is pivotally supported by a housing of an instrument panel concave portion, and a speed control device is provided between the other ends of two links each having one end pivotally connected to the housing and the glove box. Is arranged, and the opening and closing speed of the glove box is adjusted by a speed control device.However, since the speed control device is provided between the housing and the glove box, the gap becomes relatively large. There is a problem that the volume in the glove box is reduced accordingly, and in the device that regulates the speed by restricting the oil flow, the viscosity of the oil is greatly affected by the temperature of the vehicle interior, and the governing characteristics are reduced. There was a problem of change.

SUMMARY OF THE INVENTION An object of the present invention is to provide a compact damper device which can prevent a glove box of a vehicle from opening suddenly without a sense of moderation.

[0004]

SUMMARY OF THE INVENTION Accordingly, a damper device according to the present invention includes a support having a different diameter section formed on a side wall surface of a vehicle body, and a spring clip for elastically sandwiching the support. The support is disposed substantially coaxially with a pivot point at the lower end of the glove box with respect to the side wall surface of the vehicle body, and the spring clip is engaged with the lower end of the glove box to rotate the glove box around the pivot point. Accordingly, the support is displaced around the support so that when the glove box is closed, it engages with the small diameter portion of the support, and when the glove box is fully opened, it engages with the large diameter portion of the support. Is configured.

Therefore, when the glove box is opened by rotating it around the pivot point on the side wall surface of the vehicle body, the spring clip is engaged with the small diameter portion of the support at the beginning of opening of the glove box. Although a large resistance does not act on the rotation, the spring clip engages with the large diameter portion of the support when the glove box is fully opened, so that a relatively large resistance acts on the rotation of the glove box. The glove box can be easily prevented from being fully opened suddenly without a sense of moderation due to the above-described resistance. On the other hand, in the damper device, the clip elastically sandwiches the support having the different diameter cross section formed on the side wall surface of the vehicle body. Because of the compact structure in which the lower end of the glove box is engaged with the clip, the distance between the side wall of the vehicle and the glove box should be relatively small. It can be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be described below. The instrument panel and / or lower panel body side wall surface 1 of the vehicle defines a recess 2 that opens to the rear and inside of the vehicle, and the recess 2
Notched cylindrical portions 4 are respectively formed in the vehicle width direction at the left and right lower ends in the vehicle width direction of the glove box 3 disposed therein, and the cylindrical portions 5 are formed on the vehicle body side wall surface 1 adjacent to the notched cylindrical portions 4 respectively. Are formed in the vehicle width direction, and hinges 7, 7 are formed by press-fitting a shaft 6 inserted and fixed in the cylindrical portion 5 into the cutout cylindrical portion 4, and the The left and right lower ends are pivotally supported on the vehicle body side wall surface 1 by hinges 7, respectively, and the upper end of the glove box 3 on the vehicle interior side is locked to the vehicle body side wall surface 1 by hooks and latches 8 so as to be freely detachable.

A projection 10 is provided forwardly of the vehicle at the center lower end of the glove box 3 in the vehicle width direction, and a shaft 6 is provided at the lower end of the vehicle body side wall surface 1 facing the projection 10.
A support 11 having a different diameter section extending substantially coaxially with the support 11 is provided. A spring clip 12 made of a spring steel plate elastically sandwiches the support 11, and upper and lower arms 13, 13 of the spring clip 12.
Engages with the protrusion 10 of the glove box 3 to form the damper device 14.

In the damper device 14, when the glove box 3 is closed, the arm 1 of the spring clip 12
3 and 13 are engaged with the small diameter portion of the support 11, but when the hook and the latch 8 are released and the glove box 3 is rotated rearward by the hinges 7 and 7 and opened, the glove box 3 is closed. With the rotation, the projection 10 becomes the spring clip 12
Is displaced clockwise in FIG. 4 around the support 11, so that the spring clip 12 is gradually expanded by the support 11 having a different diameter cross section against its own spring force, and the glove box 3 is fully opened. At this time, the spring clip 12 is engaged with the large-diameter portion of the support 11 as shown by a two-dot chain line in FIG.

That is, when the glove box 3 is opened and closed, the frictional force always acts due to the elastic contact between the notched cylindrical portion 4 and the shaft 6 at the hinges 7, 7, and the glove box 3 suddenly moves without a sense of moderation. The spring clip 12 is engaged with the small-diameter portion of the support 11 when the closed glove box 3 starts to open, while a large resistance force acts on the rotation of the glove box 3 while the glove box 3 is fully opened. Therefore, the glove box 3 can be opened relatively easily by its own weight.
When the glove box 3 is fully opened, the spring clip 12 engages with the large-diameter portion of the support 11 and expands sufficiently, so that a relatively large resistance force acts on the rotation of the glove box 3. From this point, it is possible to easily prevent a sudden full opening without a sense of moderation, and it is possible to give the glove box 3 a sense of high quality.

The vehicle body side wall surface 1 and the glove box 3
Between the hinges 7, 7 are provided,
A spring clip 12 sandwiches a support body 11 having a different diameter section formed on the vehicle body side wall surface 1, and a damper device 14 is provided in which an arm portion 13 of the spring clip 12 is engaged with a projection 10 at a lower end of the glove box 3. Therefore, the distance between the vehicle body side wall surface 1 and the glove box 3 can be made relatively small, and there is a great advantage that the volume in the glove box 3 can be easily increased.

Further, since the structure of the damper device 14 is very simple, the manufacturing cost can be easily reduced, and there is an advantage that the use temperature is not particularly limited.

In the above embodiment, the damper device is provided at one place between the side wall surface of the vehicle body and the glove box. However, a plurality of damper devices may be provided at appropriate intervals in the vehicle width direction. Needless to say.

[0013]

In the damper device according to the present invention,
The support having a different diameter section formed on the side wall surface of the vehicle body is sandwiched by the spring clip, and the lower end of the glove box is merely engaged with this clip. Can be made relatively small, so that the volume inside the glove box can be easily increased, and since the structure is extremely simple, the manufacturing cost can be greatly reduced.
