DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The first embodiment of the present invention, generically shown in its operating environment in

FIG. 1

, is a frame


10


for a plastic bag


12


. The invention facilitates a single individual in emptying food and liquids into a plastic or other flexible bag without spilling its contents. Referring to

FIG. 2

, a base-supported member


16


is insertable into a base member


14


. Base member


14


includes a planar, horizontal female segment


18


having a front edge


20


and two side edges


22


(shown alternately in

FIG. 2

with phantom lines) connecting a back arc


24


from which extends an arcuate vertical first wall


26


. First wall

. Rear arc


38


of base-supported member


16


(the upper member) has a radius that is less than the radius of base member


14


by slightly more than the thickness of first wall


26


. This enables base-supported member


16


, including its vertical second wall


40


, to be slidably rotatable with respect to, and inside of, base member


14


and its vertical first wall


26


. In fact, second wall


40


can rotate 360° inside of first wall


26


. And as shown in

FIG. 3

, this enables one to save valuable space when storing the device in a drawer or cupboard.




A rivet


33


, preferably made from plastic, is used to secure member


16


to member


14


so that they may freely rotate 360 degrees with respect to each other. Rivet


33


has a vertical shank


35


extending through a center point of both male segment


32

140


and


160


consists essentially of a flat, interlocking horizontal segment integrated with an arcuate, vertical wall. Each vertical wall has a removable, arcuate, vertically telescoping extension.

FIG. 5

illustrates these four essential parts. When the two horizontal segments interlock so as to be in a ready-to-use position, the device takes the shape of a topless barrel slotted or truncated along a vertical plane through each of two opposite sides of the barrel. The bottom is horizontally extendable and the walls are vertically extendable, each having multiple locking positions. The device


510


can be disassembled and stored in a substantially L-shaped arrangement, similar to

FIG. 3

, and stacked for compact storage.




Base member


140


of female segment


180


has an arcuate, vertical first wall


260


extending from back arc


240


along a perimeter edge of base member


140


. An arcuate, vertical first wall extension


480


telescopes in and out of first wall


260


. Formed within female segment


180


is a first chamber


620


. First chamber


620


extends from front edge


200


to proximate back arc


240


. Formed within base member

620


of female segment


180


so as to maintain a plurality of locking positions. First latch


390


maintains camming engagement with two opposing inside walls of first chamber


620


, and locking engagement with each of said first latch path pairs


680


while the lateral edges


360


abut the inside walls of first chamber


620


. Simultaneous finger pressure on the outer edges of first latch


390


unlocks male segment


320


from female segment


180


so as to enable a person to change the locking positions, and thus, to change the distance between first wall


260


and second wall


400


to adapt to the size of the bag.




Formed within first wall


260


and extending from top edge


300


to proximate back arc


240


is a second chamber


640


to receive a vertical, arcuate telescoping first wall extension


480


. First wall extension


480


has an upper first rim


560


substantially normal to a pair of vertical second arms


580


. An outwardly disposed cam-type second latch


600


defines a free end of the pair of second arms


580


. For receiving the extension


480


, formed within first wall


260


is a plurality of oppositely disposed second latch path pairs


700


. These pairs of pathways extend from second chamber


640


to each of the vertical edges


280


of first wall


260


. First wall extension


480


is slidably insertable into first wall


260


so as to maintain a plurality of locking positions. Second latch


600


maintains camming engagement with two opposing inside walls of second chamber


640


, and it maintains locking engagement with each of second latch path pairs


700


. Similar to the interlocking horizontal segments, simultaneous finger pressure on outer edges of second latch


600


unlocks first wall extension


480


from first wall


260


so as to enable a person to vary the locking positions, and therefore, to vary the height of base member


140


.




Formed within second arcuate wall


400


, and extending from upper edge


440


to proximate rear arc


380


is a third chamber


660


to receive a vertical, arcuate telescoping second wall extension


460


. Second wall extension


460


has an upper second rim


500


substantially normal to a pair of vertical third arms


520


. An outwardly disposed cam-type third latch


540


defines a free end of the pair of third arms


520


. For receiving the extension


460


, formed within second wall


400


is a plurality of oppositely disposed third latch path pairs


720


. These pairs of pathways extend from third chamber


660


to each of the upright edges


420


of second wall


400


. Second wall extension


460


is slidably insertable into second wall


400


so as to maintain a plurality of locking positions. Third latch


540


maintains camming engagement with two opposing inside walls of third chamber


660


, and it maintains locking engagement with each of third latch path pairs


720


. Again, simultaneous finger pressure on outer edges of third latch


540


unlocks second wall extension


460


from second wall


400


so as to enable a person to alternate the locking positions, and therefore, to alternate the height of base-supported member


160


. Thus, the present invention can accommodate bags having various volumes.




A second embodiment is drawn to a horizontally and vertically extendable book shelf bag support


510


, shown in

FIGS. 5 and 6

. Second wall


400


extends below the horizontal plane of male segment


320


by a distance equal to approximately one half of the thickness of female segment


180


so as to form a leg


740


for member


16


such that male segment


320


maintains horizontal alignment with first chamber


620


of female segment


180


. A bottom surface of female segment


180


can have a plurality of rubber feet


760


to improve traction. Another gripping feature can be found in first rim


560


and second rim


500


(

FIG. 5

) which are capped with a rubbery material to facilitate the grip on the opening circumference of plastic bag


12


.





FIGS. 7A

,


7


B and


7


C illustrate a third embodiment drawn to another book shelf bag holder frame


800


. A rectangular base plate


810


has three blind grooves


820


,


830


and


840


of equal length formed from a front edge


850


, but not extending the entire width of the base plate


810


. It can be appreciated that the distance between groove


820


and


830


is shorter than the distance between


830


and


840


to accommodate different sized bags. Walls


860


shown in

FIG. 7A

are taller than the single wall


870


depicted in

FIG. 7B

to show the relative height difference.




A critical feature of this embodiment is the configuration of the bottom partial pentagonal portions


880


of each wall


860


and


870


, to fit snugly in the pentagonal shaped grooves


820


,


830


and


840


which are commensurate in length with the widths of the walls


860


or


870


. A corrugated rubber layer


890


is positioned under the base plate


810


for preventing slippage on a smooth counter surface.




Thus, a taller and wider plastic bag


900


can be readily accommodated by locating the taller walls


860


in the outside grooves


820


and


840


as depicted in

FIG. 7A

with the lip


910


disposed over the walls


860


. A smaller bag can be framed with the shorter walls


870


shown in FIG.


7


B. Then, the frame


800


can readily be dismantled and stored as a flattened package when not in use.
