<Prior art> In an ashtray installed in the interior of a car, when the front of the stored ashtray body is pushed toward the back and then released, the lock is released and the ashtray moves in the extraction direction.
Japanese Unexamined Patent Publication No. 145633/1983 discloses a structure in which the movement of the ashtray body is decelerated from the vicinity of the extraction end to extract the ashtray body, the extracted ashtray body is pushed in the storage direction, and then locked at the storage position.

<Problem to be solved by the invention> In the conventional structure described above, as a means for pushing the ashtray main body in the extracting direction, coil springs are inserted between the left and right sides between the back wall of the housing and the back end surface of the ashtray main body. This configuration requires two coil springs, and requires a large number of parts and assembly man-hours.

Further, the movement deceleration means for the ashtray body includes a bellows between the two coil springs, which are opposed to each other between the rear wall of the housing and the rear end surface of the ashtray body, and a narrow passageway that acts to throttle the air sucked into the bellows. If the check valve becomes clogged with dirt or the like, its function will be impaired, and the structure is complicated, causing problems in the durability of the bellows.

Furthermore, the locking mechanism of the ashtray body includes a latch attached and supported by a bolt to the inner wall of the housing so that it can pivot vertically and tilt toward the side wall of the housing, and an engagement pin that engages and disengages from this latch is attached to the inner wall of the ashtray body. The latch is provided protruding from the side wall, and the engaging pin is used to tilt the latch to allow extraction and movement of the ashtray body.

Therefore, in order to tilt the latch, it is necessary to assemble the latch while adjusting the way in which it is attached and supported to the bolt appropriately, which complicates the assembly work.

<Means for Solving the Problems> In order to solve the above-mentioned conventional problems, the present invention provides a box 1, an ashtray main body 2 guided in the box 1 so that it can be stored and extracted, and the box 1. The bottom surface 1b is attached to the bottom surface 1b by the rotating shaft 4.
A pin 5 is provided on the rear end surface of the ashtray main body 2 so as to be rotatable in the moving direction of the ashtray main body 2 in a plane parallel to the ashtray main body 2.
a spring 7 that urges the actuating arm 3 in the extraction direction of the ashtray main body 2; and a spring 7 that is connected to the back wall 1a of the box 1 and the actuating arm 3 and an air damper for buffering near the extraction moving end; a stopper pin 11 protruding below the bottom surface of the ashtray body 2; A locking pawl 8 is pivotally supported by a rotating shaft 9 in a direction perpendicular to the moving direction of the ashtray body 2 in a plane parallel to the bottom surface 1b, and a rotation range of the locking pawl 8 is It consists of a stopper shaft 12 for regulating, and a spring 10 for biasing the locking pawl 8 to a neutral position within the turning range regulated by the stopper shaft 12. A locking groove 13 that locks the stopper pin 11 at the storage position of the ashtray main body 2 toward the back wall side, and a locking groove 13 that locks the stopper pin 11 at the storage position of the ashtray main body 2, and a locking groove 13 that locks from the open end of the locking groove 13 to one side with this locking groove 13 in the center. An inclined guide surface 14 inclined outward toward the tip of the locking pawl 8 and a convex arc-shaped guide surface 15 formed on the other side from the tip of the inclined guide surface 14 toward the open end of the locking groove 13. This is what I did.

<Function> With the above configuration, the ashtray main body 2 is connected to the operating arm 3.
is always biased in the extraction direction, and the stopper pin 1
1 is locked in the locking groove 13 of the locking pawl 8 and held at the storage position.

In this state, by pushing the ashtray body 2 a little, the stopper pin 11 comes off the locking groove 13 and moves to the inclined guide surface 14 of the locking pawl 8, and by releasing the pushing force of the ashtray body 2,
is moved in the extracting direction by the operating arm 3, and the stopper pin 11 slides on the inclined guide surface 14 to rotate the locking pawl 8, allowing the ashtray main body 2 to be moved for extraction.

In the vicinity of the extraction movement end of the ashtray body 2, the air damper 6 weakens the turning force of the operating arm 3 to provide a buffering effect.

By pushing the ashtray main body 2 from the extraction end in the retracting direction, the stopper pin 11 slides into contact with the convex arc-shaped guide surface 15 of the locking claw 8, causing the locking claw 8 to rotate, and the stopper pin 11 is inserted into the locking groove 13. Guide, ashtray body 2
At the retracted position, the stopper pin 11 is locked in the locking groove 13 by biasing and turning the locking pawl 8 to the neutral position.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a box in which an extractable ashtray main body 2 is stored. An operating arm 3 is mounted on the bottom surface 1b in this box 1 so as to be able to rotate in the direction of movement of the ashtray body 12 in a plane parallel to the bottom surface 1b.
is supported by a rotating shaft 4, and a pin 5 that abuts the rear end surface of the ashtray body 2 is fixed on the tip of the operating arm 3.
The operating arm 3 is biased by a spring 7 with a turning force in the direction of pushing out the ashtray main body 2 and opening, and constantly presses the ashtray main body 2 in the pushing out direction via the pin 5. Further, an air damper 6 between the actuating arm 3 and the back wall 1a of the box 1 is connected via a rotating shaft. A stopper pin 11 is provided protruding from the bottom of the ashtray body 2.

Reference numeral 8 denotes a locking pawl that is a component of a locking device that locks the ashtray main body 2 in the storage position within the box 1. This locking claw 8 is located on the bottom surface 1b inside the box 1.
The stopper pin 11 is pivotally supported by a rotating shaft 9 near the movement locus line thereof so as to be able to turn in a plane parallel to the bottom surface 1b with its tip facing toward the opening side of the box 1. As shown in FIG. 3A, this locking pawl 8 has both ends of a spring 10 that is spirally wound around the rotation shaft 9 and crosses in contact with both sides of the locking pawl 8. A spring 10 abuts on both sides of a stopper shaft 12 protruding from the bottom surface 1b of the box 1 in parallel with the rotating shaft 9, thereby regulating the rotation range of the locking pawl 8.

A locking groove 13 for locking the stopper pin 11 and a locking groove 1 are provided at the tip of the locking pawl 8.
The stopper pin 11 released from the ashtray body 3 slides into contact with the slanted guide surface 14 that rotates the locking pawl 8 and allows the ashtray body 2 to be pushed out, and the ashtray body 2 that has been pushed out.
By pushing box 1 inward, stopper pin 1
1 to the locking groove 13.

Next, the operation of the above configuration will be explained. When the ashtray body 2 is stored in the box 1, the stopper pin 11 is locked in the locking groove 13 of the locking pawl 8, and the spring 7 of the operating arm 3 is held in the ashtray body 2, as shown in FIG. 3A. It accumulates repulsive force in the direction of pushing out.

When opening the ashtray main body 2 in this state, the ashtray main body 2 is pushed slightly inward into the box 1. As a result, the stopper pin 11 is released from the locking groove 13 as shown in FIG. 3B, and the locking pawl 8 is displaced to one side by the spring 10 as shown in FIG. 3C. When the push of the ashtray main body 2 is released in this state, the ashtray main body 2 is pushed in the pushing direction by the operating arm 3, the stopper pin 11 slides along the inclined guide surface 14, and the locking claw 8 is moved to the second position. As shown in FIG. 3D, the ashtray body 2 is further displaced to one side and the ashtray body 2 is automatically pushed out of the box 1 and opened.

When the ashtray main body 2 is pushed out, the stopper pin 11 passes the tip of the inclined guide surface 14, and the locking pawl 8 is returned to the neutral position by the force of the spring 10 as shown in FIG. 3E.

On the other hand, the ashtray main body 2 that reaches the push-out end by the operating arm 3 buffers the shock at the push-out end by the action of the air damper 6, opens gently, and then stops.

When storing the ashtray main body 2 with the above-mentioned push-out opening in the box 1, when the ashtray main body 2 is pushed inward into the box 1, as shown in FIG. Guide surface 15
The stopper pin 11 comes into contact with the stopper pin 11, and as shown in FIG. Stoppin 1
1 passes the end of the convex arc-shaped guide surface 15 as shown in FIG. Lock in the stored position.

<Effect of the invention> As described above, according to the invention, the actuation arm 3 is provided on the bottom surface 1b of the box 1 so as to be pivotable in the moving direction of the ashtray body 2, and the actuation arm 3 is rotated in the extraction direction of the ashtray body 2. Since the structure is such that the ashtray main body 2 is always biased in the extraction direction by the spring 7 that biases the ashtray, two coil springs unlike the conventional one are not required.

Furthermore, as is clear from the drawings, the air damper 6 is of a piston-cylinder type, so it is durable and does not have a complicated structure like the conventional bellows and check valve type.

Further, the locking mechanism of the stopper pin 11, which is a locking and unlocking mechanism for the ashtray main body 2, is arranged on the bottom surface 1b of the box 1 near the movement locus of the stopper pin 11, with its tip facing toward the opening side of the box 1, and facing the rotating shaft 9. Therefore, the locking pawl 8 is pivotably supported in a plane parallel to the bottom surface 1b in a direction orthogonal to the moving direction of the ashtray body 2, and the stopper shaft 12 restricts the rotation range of the locking pawl 8. It consists of a spring 10 that urges the locking pawl 8 to a neutral position in the rotation range regulated by the stopper shaft 12, and the tip of the locking pawl 8 has an opening facing the back wall of the box 1; a locking groove 13 that locks the stopper pin 11 in the storage position of the ashtray main body 2;
On one side of the center, there is an inclined guide surface 14 that slopes outward from the open end of the locking groove 13 toward the tip of the locking pawl 8, and on the other side, from the tip of the slope guide surface 14 to the tip of the locking claw 8. Since the convex arc-shaped guide surface 15 is formed toward the open end of the stop groove 13, it is difficult to properly mount the bolt for tilting and deforming the latch toward the side wall of the housing, as in the conventional method. It has the advantage of eliminating the need for adjustment and assembly work and ensuring reliable locking and unlocking.
