Description

BACKGROUND OF THE INVENTION

The present invention relates to ash receivers to receive a lighted cigar or cigarette therein and put out the same, and more particularly to a drawer type ash receiver adapted to be secured to an instrument panel of a vehicle.

In known drawer type ash receivers, a container in the form of a drawer is telescopically suspended by a stationary supporting member secured to the instrument panel in such a manner that the container is air-tightly covered by the supporting member in fully closed position to extinguish sparks of cigar or cigarette ends within the container. The supporting member is generally formed in a half-box shape from sheet metal cut in a proper shape by bending both side edges and the closed end edge. There are, however, undesired slit spaces between the bent side flanges and the bent flange at the closed end. The slit spaces decrease the air-tightness of the container in fully-closed position. This creates a danger that cigar or cigarette ends stored in the container may be ignited by a fresh butt thrown in before it is fully extinguished, since the fresh butt may keep smoking and resume a fully-lit condition with the help of the air supplied through the slit spaces. To avoid this kind of danger, some sealing members have to be additionally adapted to ensure the air-tightness of the closed container.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a drawer-type ash receiver assembly in which a supporting member for a container is formed in a half-box shape from sheet metal by stamping to have closed corners so as to avoid the above-mentioned drawbacks.

Another object of the present invention is to provide a drawer type ash receiver assembly, having the above-mentioned characteristics, in which the formation of the supporting member can easily and precisely be finished by stamping.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In a preferred embodiment of the present invention illustrated in FIGS. 1 to 4, an ash receiver assembly 10 comprises a supporting member 11 adapted to be secured to the under side of an instrument panel of a vehicle and an ash container 12 in the form of a drawer telescopically suspended by the supporting member 11.

The supporting member 11 is formed in a half-box shape from sheet metal by stamping to have a trapezoidal cross-section, as best shown in FIG. 2. In this formation, opposite-spaced sides flanges 13, 14 and a closed end flange 29 of the supporting member 11 are formed in one piece to provide closed corners therebetween and are downwardly and outwardly flared to circumscribe the three flanged rims 19, 20 and 28 of the container 12. The supporting member 11 is provided at the forward portion thereof with opposite spaced arms 13a and 14a which are inwardly extended from the respective side flanges 13 and 14 to provide a carrier for slidable movement of the container 12. Each of the arms 13a and 14a is provided at the inside thereof with bowed leaf springs 15 and 16 which are secured at the center thereof to each of the arms 13a and 14a by rivets 17 and 18.

The ash container 12 is made of heat-resistant synthetic resin and includes a finger knob 24 formed at the front thereof and a snuffer element 25 formed at the inside thereof to facilitate putting out cigars or cigarettes. Each of the flanged side rims 19 and 20 of the container 12 is provided at the outside thereof with tapered surfaces 19a and 20a which are formed complementary to the flared side flanges 13 and 14 of the supporting member 11 and extend from the forward end to the rearward end of the container 12. Each of the flanged side rims 19 and 20 is further provided at the bottom side thereof with taper surfaces 19b and 20b which are resiliently received by the opposite spaced arms 13a and 14a of the supporting member 11 by way of the leaf springs 15 and 16 to provide slidable engagement of the outside tapered surfaces 19a and 20a of the container 12 against the flared side flanges 13 and 14 of the supporting member 11.

At the rear end of the container 12, a pair of stop projections 21 are formed at both sides of the rear flanged rim 28 to be engageable with a pair of detents 22 provided on the forward region of the supporting member 11. The stop projections 21 engage the detents 22 to limit the outward movement of the container 12 when the container 12 is pulled outwardly into open position, as indicated by the dotted lines in FIG. 4. The rear flanged rim 28 is also provided with an end taper surface 28a complementary to the closed end flange 29 of the supporting member 11 and further provided with a bottom surface 28b engageable with a holding lug 23 which is extended inwardly from the closed end flange 29 of the supporting member 11. The resilient engagement of the rear flanged rim 28 against the holding lug 23 acts to secure the container 12 in fully closed position without rattling. Furthermore, the container 12 is provided at the forward end thereof with a stepped portion 27 engageable with a front end flange 26 of the supporting member 11. The stepped portion 27 has a flat surface 27a which is air-tightly engaged with the inside wall of the supporting member 11 due to biasing force of the leaf springs 15 and 16.

In practical use of the ash receiver assembly, the supporting member 11 is secured to the under side of the instrument panel (not shown) in the substantially horizontal direction, and the container 12 is telescopically supported on the opposite spaced arms 13a and 14a of the supporting member 11 with the leaf springs 15 and 16 depressed. In this assembly, when the container 12 is in fully-closed position, the rear flanged rim 28 of the container 12 is resiliently engaged with the holding lug 23 of the supporting member 11 so that the front stepped portion 27 of the container 12 is air-tightly engaged with the front end flange 26 of the supporting member 11, and the three flanged rims 19, 20 and 28 of the container 12 are also air-tightly engaged with the flared flanges 13, 14 and 29 of the supporting member 11 to hermetically close the interior of the container 12.

When the container 12 is pulled outwardly by the knob 24 into fully-open position, as indicated by the dotted lines in FIG. 4, the container 12 is released from the resilient engagement of the rear flanged rim 28 against the holding lug 23 of the supporting member 11 and engages at the rear projections 21 thereof with the detents 22 of the supporting member 11 to limit the outward movement of the container 12. The outward movement of the container 12 is guided by frictional engagements of the side flanged rims 19 and 20 of the container 12 against the flared side flanges 13 and 14 of the supporting member 11. To remove the container 12 completely for purposes of emptying the contents thereof, the forward end of the container 12 is merely moved upwardly in fully-open position so that the container 12 rotates counterclockwise around the front end 26 of the supporting member 11 to separate the projections 21 of the container 12 downwardly from the detents 22 of the supporting member 11.

In order to replace the container 12 after removal, it is simply necessary to insert the container 12 into the supporting member 11 until the projections 21 over-ride the detents 22 in such a manner that the side flanged rims 19 and 20 of the container 12 are resiliently received at the bottom tapered surfaces 19b and 20b thereof by the springs 15 and 16 on the arms 13a and 14a. When the container 12 is pushed into fully closed position, the interior of the container 12 is air-tightly closed by means of the side and closed-end flanges 13, 14 and 29 of the supporting member 11 circumscribing the three flanged rims 19, 20, and 28 of the container 12 and the front end flange 26 engaging the stepped portion 27 of the container 12 so as to put out sparks of butts stored in the container. In this instance, the flat surface 27a of the stepped portion 27 of the container 12 engages with the inner surface of the front end of the supporting member 11 in spite of any assembling tolerance to ensure the air-tightness of the container 12.

As already described, the construction shown is only an example of how the present invention can be put into practice. The present invention is, however, not restricted thereto, but modifications of the construction illustrated and also other forms of construction are possible. For example, the detents 22 of the supporting member 11 and the projections 21 of the container 12 may be arranged such that the container 12 can be removed by downward displacement thereto.
