## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority to provisional applications Ser. No. 61/050,497, filed May 5, 2008 and Ser. No. 61/144,970, filed Jan. 15, 2009.


BACKGROUND OF THE INVENTION
Drinking glasses for banquet use are usually washed in racks with the glasses inverted so as to achieve better washing and to permit washing liquid to easily drain from the glasses. These racks typically hold between 16 to 36 glasses, and the glasses are rotated into the upright position by hand after washing, in order to be filled and taken to the banquet area for distribution onto tables.
U.S. Pat. No. 6,695,563 to Guzman suggests a technique for mechanically rotating a rack of washed glasses into the upright position for filling.
SUMMARY OF THE INVENTION
The present invention comprises a system, apparatus and method for preparing a quantity of drinking glasses for filling and distribution in a facile manner that reduces the risk of unsanitary contact and glass breakage, while permitting the glasses in a rack to be quickly filled and transported into a dining area for distribution.
In accordance with the present invention, the system is provided with an open-faced chassis fitted within an area of a frame or similar holding structure, with the chassis rotatable about an axis of rotation that extends through the open face. Holding means within the chassis receives a first empty rack through the open face and into a storage position, while a second holding means within the chassis receives a second rack filled with a plurality of glasses in an inverted state through the open face and into a second portion below the first rack. Means are provided for facilitating the rotation of the chassis about the axis of rotation so that the inverted glasses in the second rack slide downwardly into an upright position in the first rack.
In a preferred embodiment, the rotatable chassis is fabricated so that the first and second racks are inserted through the open face into the chassis in a horizontal direction generally parallel with the axis of rotation, with that axis passing through an area between the first and second racks. Further, the rotatable chassis is dimensioned such that an average adult operator may easily effectuate rotation of the rotatable chassis while standing in front of the open face. To this end, the rotatable chassis is fabricated such that an imaginary extension of the axis of rotation passes through the torso of an average adult operator standing in front of the open face.
Rotation of the chassis in the preferred form is facilitated with a rotatable swivel behind a rear portion, with the axis of rotation extending through the swivel.
In accordance with another aspect of the present invention, adapters having dimensions corresponding to that of the racks and a grid of openings are provided, with each opening in each adapter corresponding in size and cross-sectional dimension to the inverted glasses in the racks. The adapters are dimensioned to fit over each rack before insertion of the racks into the rotatable chassis.
In use, the preferred form of the present invention permits the rapid preparation of a quantity of drinking glasses for first filling and then distribution of the glasses by rotating the rotatable chassis about the axis of rotation so that the inverted glasses in the second rack slide through the adapters into an upright position in the first rack. To further facilitate this operation, the adapters are provided with braking means that reduces both the potential for improper alignment and breakage of the glasses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The details of the system, apparatus and method of the present invention will now be described with reference to FIGS. 1-16.
First noting FIGS. 1 and 2, one embodiment of the system and apparatus, referred to generally by the reference numeral 10, comprises an open frame 12 formed of vertical and horizontal struts shown in FIGS. 1 and 2. This strut arrangement includes forward opposing vertical struts 14, 16 and forward opposed upper and lower horizontal struts 18, 20, respectively. As shown in FIG. 2, the strut arrangement further includes rear opposing vertical struts, including strut 22, it being understood that a strut on the opposite side thereof is hidden from view. Noting both FIGS. 1 and 2, opposing upper and lower side struts 28, 30 and 32, 34 extend rearwardly from the forward horizontal struts 18, 20 shown in FIG. 1.
Now noting FIG. 1, vertical support struts 36, 38 extend between the rear horizontal struts 28, 30 and are fitted and spaced between and parallel with the rear vertical struts, including strut 22. A swivel plate 40 is fitted between the support struts 36, 38 with a swivel 42 mounted to the plate 40. As thus constructed, the frame 12 defines an open area 44.
In accordance with the present invention, the system 10 comprises a rotatable chassis 50 for supporting two glass racks in a stacked relationship. Noting first FIGS. 1 and 2 and for illustrative purposes, exemplary first and second racks 52, 54 are shown in dotted lines with a quantity of glasses 56 (also in dotted lines) shown loaded into the second rack 54, and with the first rack 52 being empty of any glasses. Each of the racks 52, 54 are fitted at the top with an adapter 90 shown in dotted lines in FIGS. 1 and 2 and described in greater detail below with reference to FIGS. 11-16.
Once rotation of the chassis 50 about the axis A of the swivel 42 is undertaken as shown by the arrows in FIG. 1, the empty first rack 52 is rotated into the downward position, such that the glasses 56 fall through the second rack 54 and into corresponding openings in the first rack 52, as shown in FIG. 2, again using dotted lines to illustrate the racks 52, 54, the adapters 90 and the glasses 56. Preferably, the frame 10 and the rotatable chassis 50 are constructed so that the axis of rotation A extends between the first and second racks 52, 54 and adapters 90. Additionally, the frame 12 and the chassis 50 are dimensioned such that the position of the chassis 50 in the frame 12 is at a height H such that an average adult operator may easily effectuate rotation of the chassis 50. That is to say, an imaginary extension of the axis of rotation A passes through the torso of an average adult operator standing in front of the frame 12 and the open face 70 of the rotatable chassis 50.
One embodiment of the construction of the rotatable chassis 50 will now be described with reference to FIGS. 1-5, it being understood that a number of modifications may be made in this construction without departing from the spirit and scope of this invention.
First noting FIGS. 3-5, the rotatable chassis 50 is provided with a generally orthogonal arrangement of vertical and horizontal structural elements 58-69 that defines an open-face 70 into which the first and second racks 52, 54 may be inserted. Opposing mid-section rack holders 72, 74 receive one of the racks 52, 54 in one portion of the interior of the chassis 50, and with opposing rack holders 76, 78 along the four outer horizontal structural elements 60, 61, 62 and 63. As shown in FIGS. 3 and 4, a pair of vertical structural elements 82, 84 at the rear of the rotatable chassis support a swivel plate 86; as shown in FIG. 5, the swivel 42 is attached to the rear of plate 86 with spring mounts 43 as depicted in the side view of FIG. 8, and with intermediate bearing plate 41 and bearing 43.
As shown in FIGS. 6 and 7, the sliding surfaces across which the racks 52, 54 are installed into the chassis 50 are provided with cushioning to dampen the side-to-side and vertical movement of the racks and further reduce the likelihood of damage to the glasses. In FIG. 6, rail 80 extending from front to rear on the bottom of the chassis between structural elements 69 and 59 is provided with a cushioning foam layer 81. In FIG. 7, sliding element 74 is provided with foam cushion 75, it being understood that such cushioning is provided to all of the corner and mid-section sliding elements.
FIG. 9 depicts the details of another embodiment of the rack holder 76, including a space L-shaped bracket 77 fitted along the corresponding structural element (in the case of FIG. 9, structural elements 63). An alternative form of the rack support is shown in FIG. 10, utilizing a bracket 78 that is mounted upon springs 83.
FIG. 11 is a perspective illustration of one of the racks, for example rack 54, with glasses 56 positioned therein. Typically, the rack 54 is provided with an upper area of each side wall, including area 57 which is suitable for insertion of an adapter 90, such as that shown in FIGS. 12 and 13. The adapter 90 includes side walls 92, 94, 96 and 98 that are dimensioned to fit on top of the rack 54 within the volume defined by the extending dimension shown as element 57 in FIG. 11. The adapter 90 comprises a grid formed of longitudinal grid elements 100, 102 that are dimensioned to correspond to the openings in the rack 54 for glasses 56.
In accordance with another aspect of this invention, means are provided for customizing the dimension in the racks to accommodate for differences in the thickness, length and width and depending upon the weight and diameter of specific glasses to be handled by the system 10. To this end, each rack 90 is provided with brakes 104 along the periphery of each glass opening 106, the details of which are shown in FIG. 15, it being understood that the brakes 104 may be positioned along each side of the opening 106 as shown in FIG. 14.
In use, a first empty rack 52 is extended through the open face 70 of the chassis 50. Thereafter, a second, full rack 54 filled with inverted glasses 56 is extended through the open face 70 of the chassis 50 below the first rack 52 as shown in FIG. 16. The chassis 50 is then rotated about the axis of rotation A so that the inverted glasses in the second rack 54 slide into the upright position in the first rack 52, as shown in FIG. 2. Again, the brakes 104 in each adapter 90 significantly reduce the likelihood of damage to the glasses during the “flipping” of the two racks 52, 54 about the axis of rotation. It will be appreciated that an average adult operator standing in front of the open face 70 of the rotatable chassis 50 can easily rotate the chassis 50 about the axis of rotation A by grasping the handles 84 and then guiding the chassis 50 manually through the 180° rotation in order to achieve movement of the glasses from the second rack 54 to the first rack 52. Alternatively, the rotation may also be effectuated automatically by use of a motor arrangement.
Once the glasses 56 have been moved from the second rack 54 to the first rack 52, the first rack may then be removed and the glasses 56 filled with a beverage and the filled rack 52 taken to the banquet area for distribution. The second rack 54, now empty, is positioned in the upper portion of the rotatable chassis 50. A third, full rack of inverted glasses may then be inserted into the rotatable chassis 50 below the second rack 54, and the rotation of the chassis again executed and so forth as needed. It will of course be appreciated by those skilled in the art that a large quantity of glasses may very quickly be prepared for filling and distribution utilizing the system and method of the present invention.
The embodiments of the system, apparatus and method of the present invention as set out above are for purposes of illustration only and by way of example, and the scope of these inventions are not limited to the exact details of construction and use but only by the appended claims.
