HAA/E) 0: 6056 TTORNE Y5 United States Patent 3,460,876 ASH TRAY Henry De Boer, Grand Rapids, Mich, assignor to F. L. Jacobs Co., Detroit, Mich, a corporation of Michigan Filed July 19, 1967, Ser. No. 654,640

Int. Cl. B60n 3/08, 3/10, 3/12 U.S. Cl. 312-246 13 Claims ABSTRACT OF THE DISCLOSURE There is disclosed an ash receptacle or tray for installation within an automobile dashboard, including an ash receiving receptacle body or drawer slidable from a fully retracted and enclosed position within the dashboard to a fully open position forwardly of the dashboard. A housing is provided for attachment to the dashboard or other suitable support structure within the vehicle as is conventional in the art. The drawer is slidably received within the housing for withdrawal as the need arises.

The drawer has elongated guides 01' tracks on each side thereof. Each track comprises a bearing surface and a guide surface which are connected and are located approximately 90 apart. The housing is provided with a resilient tension element or tensioner, made from a plastic material, opposite each track. A single mounting element connects the tension element to the housing approximately midway between the ends thereof. Each tension element is provided with resilient bearing means and guide means which are in contact with the adjacent bearing surface and the guide surface respectively.

Specifically, each resilient tension element includes a pair of elongated cantileverly supported resilient arms interconnected on their inner ends and a pair of bearing protuberances. The resilient arms contact the corresponding bearing surface of the track and urge the drawer and in particular the bearing surface thereon into contact with the guide protuberances.

Background of the invention Numerous designs for vehicle ash trays have been made in the past. An acceptable ash tray design must meet a number of requirements. One requirement is that the ash tray construction must be susceptible to low cost manufacture. Another is that the design should be compact so as to use a minimum amount of space in the vehicle. The ash tray design must be rugged to withstand the stress of years of use in a vehicle.

Further in drawer-type ash trays, the drawer element must be easily slidable inwardly and outwardly and it must be sufficiently restrained so that it will not move without the application of an external force applied thereto. The construction must be such that the drawer will not bind or jam and that it will be maintained in proper alignment at all times. Finally, the drawer must be easily removable to permit emptying thereof.

The present invention utilizes a minimum number of parts including the resilient tension elements made from a plastic material and combines all of the aforementioned qualities to an optimum degree.

Summary of the invention The vehicle ash tray comprises a housing for fastening to a vehicle. A drawer for ashes is removably received in the housing. The drawer has an elongated track on each side thereof, each track comprising a bearing surface and a guide surface. The housing is provided with a resilient tension element or tensioner opposite each track. Each tension element includes resilient bearing means and ice guide means which are in contact with the adjacent bearing surface and guide surface respectively. Each bearing means comprises a pair of resilient arms connected on their inner ends and each guide means comprises a pair of guide protuberances. The resilient arms acting against the corresponding bearing surface urges the drawer against the guide protuberances to maintain the drawer in proper alignment in the housing.

FIGURE 1 illustrates a vehicle ash tray 10 comprising a housing 12 and a drawer or tray 14 which is removably received in the housing 12. In use, the housing 12 is secured to a suitable panel or support structure in the vehicle, usually the vehicle dashboard.

The housing 12 is made from metal and comprises an upper plate-like portion 16 having downwardly directed

side walls

18 and 20 on each side thereof. Each

side wall

18 and 20 is provided, intermediate the edges thereof, with an outwardly extending longitudinally curved zone 22 of transverse V-shaped cross section. The zone 22 includes a downwardly and outwardly extending wall portion 24 and an inwardly and downwardly extending wall portion 26 as best illustrated in FIGURE 2. The wall portion 26 terminates in a flange portion 28. Angle A between

wall portions

24 and 26 is approximately 90 as shown in FIG. 2.

The drawer 14 is made from metal and includes a bottom 30 having upwardly extending

walls

32 and 34. Each

wall

32 and 34 is provided with an outwardly extending longitudinally curved metal track 36 of substantially V- shaped cross section. Each track 36 comprises an upper downwardly and outwardly extending bearing surface 38 and a lower downwardly and inwardly extending guide surface 40. The upper ends of the

side walls

32 and 34 are provided with inwardly extending

flanges

42 and 44 respectively. Angle B, between the bearing and

guide surfaces

38 and 40, is approximately 90 as illustrated in FIGURE 2.

FIGURES 37 inclusive illustrate the resilient tension element or tensioner 50. The element is made entirely from a self-lubricating material such as a plastic material, as an example from nylon. The element 50 comprises bearing means 52 and guide means 54. The bearing means 52 are in the form of a pair of longitudinally aligned cantileverly supported resilient arms 56. The adjacent and inner ends of the arms 56 are connected by a bridge or strap portion 58. The outer ends of the arms 56 are unsupported and free. The arms 56 are provided with contacting surfaces 60 which are located in a plane 62. The surfaces 60 contact the bearing surface 38 of the corresponding track 36 with a minimum of friction contact therebetween due to the small area of contact.

The guide means 54 of each tension element 50 comprises a pair of longitudinally spaced apart guide protuberances 64 which are located on a wall or flange 66 connected to the strap 58. The flange 66 is located at one side of the resilient arms 56 as best illustrated in 3 FIGURES 3 and 7. The guide protuberances 64 are provided with contacting surfaces 68 which are located in a second plane 70.

Planes

62 and 70 intersect at approximately 90. The strap 58 is provided with a mounting opening 59 which is centrally located midway between the ends of element 50.

A pair of tension elements 50 are located in each tray 10, with one element 50 opposite each track 36. Each element 50 is connected to the housing 12 by means of a single rivet or fastener 72 which extends through the element 50 and the wall portion 24 as best illustrated in FIGURE 2. With such a construction the flange 66 abuts the wall portion 26 while the strap 58 abuts the other Wall portion 24 as best illustrated in FIGURE 2.

Each tension element or tensioner 50 is formed or molded as a single and integral unit from a plastic material such as nylon or from other self-lubricating materials which are well known in the art. The tension element 50 is resilient whereby the arms 56 function as springs. With such a construction there is no requirement for metal springs, rollers, ball bearings, etc. as in prior art devices. Thus the plastic tension element or tensioner 50 performs the various functions previously performed by metal springs and plastic rollers in some prior art devices.

It should be noted that the contacting bearing and guide

surfaces

60 and 68 of each element 50 have substantially line contact with the corresponding metal track surface thus minimizing friction contact therebetween and thereby insuring longer life and lower maintenance costs.

The drawer 14 when assembled in the housing 12 is held in proper alignment by means of the tensioners 50. The resilient arms 56 exert a biasing force on the bearing surface 38 of the drawer 14 effective to hold the guide surface 36 of the drawer 14 in contact with the guide protuberance 64 and to thus insure proper alignment of the drawer 14 as it is moved with respect to housing 12 in the usual manner.

The drawings and the foregoing specification constitute a description of the improved ash tray in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
