DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(11) This disclosure of the invention is submitted in furtherance of the Constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).

(12) A collection and sifting device for vacuumed debris generally provides a resiliently deformable body 20 and bottom cap 40 for collection of vacuumed debris within a powered vacuum 60.

(13) The body 20 has a general configuration of a truncated funnel having an open top portion 21 defining a top circumferential edge 22 and further defining a top diameter 23. A closed bottom 24 is carried by the body 20 spaced apart from the open top 21. The closed bottom 24 defines a bottom circumferential edge 25 and further defines a bottom diameter 26. A sidewall 34 extends between the closed bottom 24 and the open top 21. An interior volume 27 is defined between the closed bottom 24 and the top circumferential edge 22 and an inner surface 29 of the sidewall 34. An exterior surface 28 extends along the sidewall 34 opposite the interior volume 27. At least one handle 30 and preferably two handles 30 are carried by the body 20 proximate the top circumferential edge 22 to facilitate grasping by a user and agitation by a user. (FIGS. 2, 4). In one embodiment (FIGS. 1, 4, 5) the handles 30 are interconnected with the exterior sidewall 28 and do not extend above the top edge 22. In a second embodiment (FIGS. 2, 3) the handles 30 are interconnected with the body 20 at the top edge 22 and extend upwardly therefrom. The handle 30 placement is generally controlled by available space within the volume 65 of the vacuum 60. (FIG. 8).

(14) A plurality of spacedly arrayed through holes 31 are defined in the closed bottom 24 and in the sidewall 34 proximate the closed bottom 24. The holes 31 communicate between the interior volume 27 and the exterior of the body 20. As shown in FIG. 7A, each hole 31 has a diameter 32 and the diameter 32 is less than approximately 18 mm and is less than the diameter of a U.S. dime.

(15) As shown in FIGS. 2, 3 in a second contemplated embodiment, a locking protrusion 32 may be carried on the exterior circumferential surface 28 of the sidewall 34 to provide a locking attachment for the bottom cap 40 so as to secure the bottom cap 40 in a closed position relative to the body 20.

(16) In the preferred embodiment, the handles 30 carried by the body 20 are at generally diametrically opposed positions on the body 20 and in the preferred embodiment the body 20 is formed of rubber, fiber reinforced rubber or a flexible thermoplastic. Materials other than those specifically identified herein may likewise be used to form the body 20 and the bottom cap 40 so long as the materials are durable, flexible, resilient and have retentive memory and are resistant to wear and tear during use. Flexibility is necessary because access doors 67 defined in vacuum housings 65 are typically dimensionally smaller than the body 20.

(17) The bottom cap 40 is somewhat “cake-pan” like in configuration and is generally circular. The bottom cap 40 has an upper surface 41, an opposing bottom surface 42 and a circumferentially extending sidewall 43 that extends somewhat angularly upwardly and outwardly from the upper surface 41. The bottom cap 41 further has an inside diameter 44 that is slightly larger than the diameter 26 of the bottom of the body 20 so that the circumferentially extending wall 43 of the bottom cap 40 covers and obstructs the holes 31 defined in the sidewall 34 of the body 20 when the bottom cap 40 is in a closed orientation (FIGS. 2, 4). The bottom cap 40 is preferably formed of the same material as the body 20, but may also be formed of a different material.

(18) In one embodiment, the bottom cap 40 is hingedly attached to the body 20 by means of a hinge 45 (FIG. 7) so that the bottom cap 40 may pivot outwardly from the body 20 to unobstruct the holes 31 (FIG. 9) during sifting. In another contemplated embodiment, the bottom cap 40 has one handle 47 that is diametrically opposite an interconnection 50 of the bottom cap 40 to the body 20. The one handle 47 cooperates with a handle 30 carried by the body 20 so that when a user grasps the two handles 47, 30 simultaneously, the body 20 and bottom cap 40 can be easily manipulated in unison. (FIG. 4). Handle 47 extends angularly and upwardly from the circumferentially extending wall 43 by means of a handle strap 48. (FIG. 5).

(19) As noted previously in a second embodiment, a latch 46 may be carried by the bottom cap 40 at a position generally diametrically opposite the hinge 45. The latch 46 is releasably engagable with the locking protrusion 33 carried on the exterior circumferential surface 28 of the sidewall 34 of the body. (FIGS. 2, 3).

Operation

(20) Having described the structure of my collecting and sifting device for vacuumed debris, its operation may be understood.

(21) The body 20 is oriented so that the bottom cap 40 engages therewith by pivoting about the connection 50 so that the upper surface 41 of the bottom cap 40 is immediately adjacent the exterior bottom 24 of the body 20, and the circumferentially extending wall 43 carried by the bottom cap 40 covers or otherwise obstructs the holes 31 defined in the closed bottom 24 and in the sidewall 34 proximate the closed bottom 24.

(22) In the embodiment where the bottom cap 40 carries handle 47 diametrically opposite the interconnection 50, the handle 47 may be cooperatively engaged with a handle 30 carried by the body 20 so that a user may simultaneously grasp the handles 47, 30 to keep the bottom cap 40 engaged to the body 20.

(23) In the embodiment where the bottom cap 40 carries a latch 46 (FIGS. 2, 3), the latch 46 is engaged with the locking protrusion 33 carried on the exterior surface 28 of the sidewall 34 so that the bottom cap 40 is positionally secured in a closed orientation, as seen in FIG. 2.

(24) The body 20 and the engaged bottom cap 40 are placed within interior of the vacuum housing 65 (FIG. 8) through an access door 67 at a location therein so that debris 81 vacuumed up by the vacuum 60 by means of the vacuum hose 64 are collected and deposited into the interior volume 27 defined by the body 20.

(25) In the preferred embodiment, both the body 20 and the bottom cap 40 are formed of a flexibly resilient material such as rubber or flexible thermal plastic having retentive memory and that is durable and easy to clean. The flexibility of the material forming the body 20 and bottom cap 40 is essentially when an access door 67 is smaller than the body 20. Further, in the preferred embodiment, the diameter 23 of the top portion 21 is substantially similar to an interior diameter (not shown) of the vacuum housing 65 so that the great majority of vacuumed-up debris and the like are collected within the interior volume 27 and only minimal amounts of vacuumed-up debris fall between the upper circumferential edge 22 of the body 20 and the interior surface (not shown) of the vacuum housing 65.

(26) The vacuum 60 is operated as is customary wherein customers vacuum up debris, typically from the interiors of their motor vehicles, and the vacuumed up debris 81 are collected in the interior volume 27 of the body 20 within the vacuum housing 65. After some period of time, depending on the amount of use, the operator removes the body 20 and the engaged bottom cap 40 from the interior of the vacuum housing 65 by simultaneously removing the body 20 and bottom cap 40 through the access door 67. Because the access door 67 may have dimensions smaller than the body 20, the flexible resiliency of the body 20 allows the body 20 to be manipulated into and out of the vacuum 60.

(27) As shown in FIG. 9, the user grasps the body 20 and the closed bottom cap 40 containing the vacuumed up debris 81, and orients the body 20 and closed bottom cap 40 vertically above a trash receptacle 80, such as a garbage can having an open top. Once oriented above the opening of the trash receptacle 80, the bottom cap 40 is disengaged from the body 20 allowing the bottom cap 40 to pivot downwardly and away from the body 20 which unobstructs the holes 31 defined in the closed bottom 24 and sidewall 34 of the body 20. The user would then agitate the vacuumed-up contents of the body 20 such as by shaking. Particles, dust, dirt and the like having diameters smaller than the diameter 32 of the holes 31 pass through the holes 31 and into the trash receptacle 80. Larger items, including coins and change and waste having diameters greater than the diameter 32 of the holes 31 are retained within the interior volume 27 of the body 20. Valuables, including coins and dollar bills that were vacuumed up, remain within the interior volume 27 so that they may be collected by the user. Larger debris that have no value, such as pieces of paper and plastic and the like, are easily separated from the valuables retained within the interior volume 27.

(28) After the collected debris and valuables have been sifted, separated and collected or disposed of, the bottom cap 40 is reengaged with the body 20 and the combined body 20 and bottom cap 40 are replaced in the vacuum interior 65 through the access door 67 for continued operation and collection of debris.
