DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, 1 is a storage box exemplified as a drawer type ashtray for an automobile, and 2 is a well-known mounting plate which is slidably held on the lower surface of the ashtray and fixed to the body of the automobile. A housing, 3 is a first arm pivotally attached at one end to the rear lower surface of the housing, 4 is a second arm pivotally attached at one end to the rear end of the storage box, and 5 is a first arm on the other end of the second arm.
3 shows a pivot about which the other end of the arm is pivotally mounted. The second arm has a hole 4'through which the pivot shaft 5 is rotatably passed at the other end, and a circular recess 6 concentric with the hole, the recess being the surface opposite to the overlapping of the first arm, that is, the lower surface. It is open to the public.

The pivot 5 has an integral collar 7 which fits in the recess 6 near the lower end, and a portion 5a immediately below the collar 7 is circular, and a sealing plate 8 is fitted therein, and other than the circular shape below it. For example, a braking plate 9 is fitted on the oval lower end 5b. Then, the pivot 5 is passed through the hole 4'of the second arm from below so that the brim is housed in the recess 6, and the peripheral edge of the upper surface of the seal plate 8 is fixed to the lower end surface of the cylindrical wall 6'forming the recess 6 by swaging. Then dent 6
And a viscous fluid such as silicon grease is applied to the upper and lower surfaces of the braking plate 9 so that the braking plate 9 can rotate in the cap 10 which is fitted and fixed to the cylindrical wall from below.

Further, the first arm also has a hole 3'for passing the pivot 5 at the other end, but the shape is other than circular, for example, oval, and correspondingly, it projects from the upper surface of the second arm, The upper end 5c of the pivot passing through the hole 3'is also oval, for example. Therefore, the upper end 5c of the pivot is passed through the hole 3'and the first arm is superposed and pivotally mounted on the second arm, and the c-shaped clip 11 is provided in the annular groove at the upper end of the pivot projecting upward from the first arm. By assembling both arms 3 and 4 in a pivotally connected state to form a rotary damper device, and pivoting the pivot shaft 5 integrally with the first arm 3 when bending and extending both arms to open and close. Rotation of the brake plate 9 integrally with the pivot 4 can be braked by the viscosity of silicon grease or the like. In order to enhance the braking effect, the braking plate 9 may be provided with a plurality of radial holes.

The first arm 3 has a cylindrical portion 3b which is concentric with the hole 3'at the other end, and the lower end of the cylindrical portion overlaps the other end of the second arm. A coil-shaped spring 17 fitted around the pivot 5 is accommodated in the cylindrical portion 3, and the upper end of the spring is bent upward so as to project above the upper surface of the first arm, and tangentially from the lower end. The protruding end 17 ′ is brought out of the cylinder from between the lower end of the cylindrical portion 3 b and the upper surface of the second arm, bent downward, hooked on the second arm 4, and pushed to close the open ashtray. The movement of the first and second arms causes the spring 17 to be crimped and then accumulates a biasing force for opening the ashtray.

A projection 18 is provided on one of the surfaces of the first arm and the second arm which face each other, and a cam plate 19 which is actuated by the projection is provided on the other of the surfaces. Maintains the closed position against the bias. The cam plate 19 has a shaft 19 'on the upper surface of the second arm 4 in this embodiment.
One end of a coil-shaped spring 20 which is pivotally mounted on the shaft 19 'is hooked on the second arm and the other end is hooked on the cam plate 19 to elastically press the stopper 21.

Push the ashtray in, and
The projection 18 contacts the side surface 19a of the cam plate 19 slightly before the second arms 3 and 4 pivot about the pivot 5 and is folded up and down (FIG. 4I), and then the cam plate is biased by the spring 20. The side surface 19a is slidably contacted while being rotated so as to be pushed back (FIG. 4II). The cam plate has an inlet 2 on the side surface 19a.
When the ashtray is pushed in as described above and the ashtray is pushed a little way past the closed position and both arms 3 and 4 are folded up and down, the projection 18 is folded up and down. Cam groove inlet 22a opened on the side of the cam plate
To reach. As a result, the cam plate 19 which has been rotated against the spring 20 draws the projection 18 into the cam groove from the inlet 22a, hooks the projection on the intermediate bent portion 22 ', and stops.
The self (cam plate) is slightly rotated toward the stopper 21 by the urging force of the spring 20 (FIG. 4III), and the ashtray is the spring 1.
The urging force of 7 slightly pushes it back to close it, and the projection 18 is caught by the bent portion 22 'of the cam groove.
Cannot be opened further by the biasing force of the spring 17 and thus the ashtray is held in the closed position against the biasing force of the spring 17.

Next, in order to open the ashtray, the ashtray in the closed position is slightly pushed in with a finger. As a result, the protrusion 18 is disengaged from the bent portion 22 ', the cam plate 22 is moved toward the stopper 21 and is slightly pushed by the spring 20, and the passage 22c that connects the protrusion 18 to the outlet 22b.
Then, the first arm and the second arm can be rotated and opened by the urging force of the spring 17 (FIG. 4IV). Therefore, both arms pivotally open about the pivot 5 to push out the ashtray to the open position, the projection 18 goes out of the cam plate through the outlet 22b, and the cam plate rotates by the spring 20 and the stopper 21 again. (Fig. 4V). Both arms 3 and 4 are swung open by the urging force of the spring 17, and when the ashtray is pushed out, the pivot 5
Rotates with the braking plate 9 of the rotary damper device, and the rotation of the braking plate is braked by the viscosity of silicon grease or the like, so that the ashtray does not suddenly jump to the open position.

Both the entrance and the exit of the cam groove are open to the side surface 19a of the cam plate, and when the ashtray is pushed in and the projection 18 makes sliding contact with the side surface of the cam plate, the projection 18 is the exit 2 of the cam groove.
It doesn't fit in 2b. This is path 2 leading to the exit of the cam groove
2c is inclined toward the exit, and there is a step between the exit and the entrance so that the protrusion cannot enter the exit. For this reason, when the ashtray in the closed position is opened, the projection is in the path 2
When moving in 2c toward the outlet 22b, the cam plate 19
Pushes down the spring 20 a little and tilts it, and when the protrusion comes out of the outlet, it returns to its original state and is kept in contact with the stopper 21.
It can be rotated with.

When the spring 17 for urging the storage box to the open position is housed in the cylindrical portion provided at the other end of one of the first and second arms as in this embodiment, A bearing tube 2 which projects into one or both arms into the cylindrical part in order to pivotally connect the other ends of the second both arms without wobbling.
3 and 24 may be provided, and the pivot 5 may be passed through the bearing sleeve exactly. The inner shape of the hole 3'of the first arm or the bearing cylinder 23 is, for example, an oval shape, and is placed according to the outer shape of the portion of the shaft 5 passing through this.

Although the embodiment of the present invention has been described above, the storage box is not limited to the pull-out type ashtray, and may be a glove box of an automobile or a lid thereof.

[0015]

According to the present invention, the storage box moves quietly from the closed position to the open position, which does not impair the high-class interior of the vehicle and
A push-push actuated storage box is obtained in which the storage box can be moved to the open position by pushing the storage box pushed into the closed position again.
