DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Referring now in detail to the drawings and in particular to FIG. 1 thereof, a vacuum assembly 10, in accordance with one preferred embodiment of the present invention, is shown generally in operative association with a container 12 which is adapted to function as a receptacle for articles vacuumed or picked up by the assembly 10. As shown in FIG. 1, the container 12 comprises a generally cylindrically shaped side wall 14 and is closed at the lower end thereof, as will be apparent. The container may, if deired, be mounted for roll ing movement on a suitable container chassis 16 having rollable casters or the like 18 on the underside thereof. It will be appreciated, of course, that the container 12 may be of various other configurations than a right circular cylinder, as shown herein, for example, the container 12 could consist of a frustoconically shaped bucket, pail or the like well known in the art.

The container 12 is provided with a handle or bail, generally designated by the numeral 20, which is of a U-shaped configuration and comprises an arcuate central portion 22 having diametrically opposed end portions 24 and 26 at the opposite ends thereof. The end portions 24, 26 are adapted for pivotal engagement with a pair of attachment fittings 28, 30, respectively, which are located on the diametrically opposite sides of the container 12, as best seen in FIG. 3. The container 12, and in particular, the cylindrical side wall 14 thereof, defines a generally circular shaped upper marginal edge 32 and an interior chamber 34. As will hereafter be described in detail, the vacuum assembly is adapted to be mounted on the upper marginal edge 32 so as to close the top of the chamber 34 and provide a generally air tight volume therewithin. Upon energization of the vacuum assembly 10, the chamber 34 will have a reduced pressure condition existing therein relative to the ambient pressure exteriorly of the container 12, whereupon foreign material such as dirt, liquids or the like may be transferred via a suitable suction hose (not shown) into the container 12.

The vacuum assembly 10 comprises an assembly housing, generally designated by the numeral 36, which consists of an upper, generally trapezoidal shaped housing section 38 and a lower annular or circular shaped housing section 40. Extending around the outer periphery of the lower housing section 40 is a peripheral lip element 42 which is adapted to be surmounted upon the upper edge 32 of the container 12 and form a generally air tight seal therewith. It will be appreciated, of course, that the lower housing section 40 may be of various other configurations either complimentary to or different from the size and shape of the associated container 12, provided, however, that a suitable air tight seal is provided between the underside of the housing 36 and the associated container. Disposed interiorly of the vacuum assembly housing 12 is a suitable electrically energizable motor (not shown) which is adapted to be communicable with a source of electrical energy by means of a conductor 44 connected to a suitable electrical circuit by means of a manually operated on-off" switch 46 mounted on the side of the upper housing section 38, as illustrated. The underside of the vacuum assembly 10 is provided with a filtering element, representatively designated'by the numeral 48, which is intended to prevent foreign material introduced into the chamber 34 from adversely affecting the normal operation of the vacuum motor therewithin. The assembly is provided with a vacuum conduit 50 which is depicted as being generally L-shaped and comprising an upper generally horizontally disposed inlet section 52 and a lower vertically oriented outlet section 54. Upon mounting the vacuum assembly 10 upon the container 12, the outlet end 54 of the conduit 50 will be disposed interiorly of the air tight chamber 34. Accordingly, at such time that the aforesaid vacuum motor is energized, a suitable reduction in pressure will occur within the container 12, thus creating a pressure differential between the interior and exterior thereof. Means in some form of a suitable vacuum conduit or hose may be connected to the inlet end 52 of the conduit 50 for use in directing the reduced pressure condition within the container 12 toward a position adjacent or in confronting relation with the foreign material, i.e., dirt, liquids or the like, which is to be vacuumed by the assembly 10. Accordingly, due to the reduced pressure condition which exists within the container 12, the foreign material will be ingested into the aforesaid conduit and eventually will be transferred thereby to the inlet end 52 of the conduit 50 and will thereafter be communicated via the outlet end 54 into the interior of the container 12 where same will be accumulated. A suitable float operated stopper may be provided interiorly of the assembly -10 for automatically closing the air flow path to the vacuum motor to prevent water, dirt or other foreign substances from being drawn up into the rotors of the vacuum turbine powered by the motor. It will be noted that the vacuum assembly 10 will find particularly useful application in removing liquids, such as cleaning water and the like'from floors, as well as for picking up dirt and the like therefrom, although it will be appreciated that the assembly 10 will find wide and varied use other than these specific applications.

The upper vacuum housing section 38 is formed with a pair of upwardly and inwardly inclined

side wall portions

56 and 58 and with a pair of upwardly and inwardly inclined end wall portions 60 and 62. The wall portions 56-62 terminate at the upper end thereof in a generally flat top section 64 that is defined in part by an imaginary, generally horizontal plane. The central portion of the top section 64 is formed with a generally rectangular shaped recessed area 66 which is adapted to nestingly receive a vertically movable or retractable carrying handle, generally designated by the numeral 68 and which is constructed in accordance with the principles of the present invention. More particularly, the handle 68 is adapted to be moved vertically between an upper extended position, as seen by the solid line position in FIG. 3, and a lower retracted position (shown in dotted lines in FIG. 3) wherein the handle is recessed below the top section 64. The handle 68 comprises a generally U-shaped member 70 fabricated, for example, of a strip of steel or the like and includes a pair of vertically disposed, spaced

parallel end sections

72 and 74 that are integrally connected by a generally horizontally disposed top section 76. The recessed area 66 is formed with a pair of spaced apart slots or

openings

78 and 80 at the opposite ends thereof which are arranged in generally vertical registry or alignment with the

end sections

72, 74 of the member 70 and through which the lower ends of the

end sections

72, 74 extend. Suitable stop means (not shown) are provided on the lowermost portions of the

end sections

72, 74 which are disposed below the recessed area 66, which stop means are adapted to engage the underside of the recessed area 66 to limit outward movement of the handle 68. The length of the

end sections

72, 74 and the distance which the recessed area 66 is located below the horizontal plane defining the top 64 are such that when the handle 68 is disposed in its lower retracted position, the same is entirely below the plane defining the top 64, for purposes hereinafter to be described.

In accordance with one feature of the present invention, the handle 68 is formed with elongated cut-away slot 82 extending the entire length thereof. The handle 68 is also provided with a pair of handle members. generally designated by the numeral 84, which are adapted to be fixedly secured to the top section 76 adjacent the opposite sides of the cut-away slot 82, whereby to de fine an elongated recessed area adapted to nestingly receive the arcuate central portion 22 of the handle or bail 20. Accordingly, the bail 20 and handle 68 may be simultaneously manually grasped or engaged to permit the entire assemblage consisting of the vacuum assembly l0 and container 12 to be transported as a single composite unit. More particularly, at such time as it is desired to effect transport of the aforesaid assemblage, the bail 20 can be pivoted from its normally stored position, as shown in FIG. 1, to an upwardly disposed position, as shown in FIGS. 2 and 3. Thereafter, the handle 68 may be raised from its lower or retracted position in FIG. 3 to its upper extended position. As the handle 68 moves upwardly beneath the bail 20, the recess defined between the handle members 84 and the cut-away slot 82 receives the central portion 22 of the bail 20, as best seen in FIGS. 2 and 3. Accordingly, it is possible to manually grasp both of the handles 68 and bail 20 simultaneously and transport the vacuum assembly l0 and container 12 as a single or composite structure. This is extremely important in that the assemblage may be transported through the use of only a single arm or hand of the operator instead of having to use both arms as is necessary when the vacuum assembly l0 and container 12 are separated or disassembled. At such time as the assemblage has been moved to some predetermined destination, the handle 68 may be biased downwardly to its retracted position recessed below the surface of the top 64, and the bail 20 may be again moved to its inoperative position shown, for ex- .ample, in FIG. 1.

Another feature of the present invention resides in the fact that the top 64 is of a flat, horizontal configuration, and that the handle 68 is recessed entirely therebelow when it is in its retracted position. Accordingly, the entire vacuum assembly 10 may be inverted and rested or supported on a suitable flat surface so that access may be provided into the interior thereof, for example, for adjusting, repairing the filter element 48 and/or safety switches or the like located in the interior thereof. Still another feature of the present invention resides in the fact that the vacuum assembly 10 is of an extremely compact construction and is thus lightweight and easy to handle. Additionally, the assembly 10 will find universality of application due to the fact that it may be operatively associated with the various type containers other than the container 12 depicted herein, as will be appreciated by those skilled in the art.

While it will be apparent that the preferred embodiment of the invention disclosed are well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.
