ROBERT A. KURLANDER ATTORNEYS REFUSE BAG HOLDER BACKGROUND OF INVENTION A wide variety of refuse bag holders are well known. Most such refuse bag holders are adapted to support a paper bag. Closure is effected by clamping or pressing opposed top edges of the bag together by means of parallel, pivotally opposed, spring-loaded frame members, generally as are illustrated in U.S. Pat. No. 3,374,976. 7

However, there is an increasingly greater demand for refuse bags which are absolutely water and moistureproof and which may be sealed against the escape of odors, particularly for receiving disposable diapers. Most commercially available impregnated paper bags are moisture resistant but not waterproof. It would be prohibitively costly to manufacture an impregnated paper bag that was absolutely waterproof. Nevertheless, plastic bags are both waterproof and very inexpensive, frequently less expensive than nonimpregnated paper bags. In addition, the plastic bag is so flexible that it readily accepts even most irregularly shaped articles. The plastic bag is, therefore, continuously self-contouring to the shape of the material disposed therein and thereby more efficiently uses the space which it occupies. As a result, the plastic bag is obviously the container of choice.

While refuse bag holders such as that disclosed in U.S. Pat. No. 3,175,760 function well with either impregnated or nonimpregnated paper bags, they do not function well with the thin plastic bag. The principal difficulty lies in the means to secure the plastic bag to the frame of the bag holder. Existing clamping means will not suffice since the top of the plastic bag is too thin to provide sufficient body for engagement with the clamping means. Thus, if the plastic bag is to be employed, the top thereof must be reinforced; otherwise the bag will tear or slip free of the frame. In addition, the top edge of the plastic bag is so thin, that the parallel opposed frames of the holder do not completely close the bag so as to be secure against the escape of odor. It is uneconomical to manufacture special plastic bags with reinforced top edges for use in the refuse bag holders contemplated.

The present invention comprises a refuse bag holder adapted to employ ordinary, thin-walled plastic bags without reinforced tops which will produce an absolutely complete closure against even the escape of odor.

SUMMARY OF INVENTION A refuse bag holder comprising a frame, support means generally at the top of the frame to support arefuse bag in a generally vertically depending position with the top open, and releasable closure means beneath the support means for cinching the refuse bag generally radially inwardly to effect a closure thereof.

PREFERRED EMBODIMENT OF INVENTION The objects and advantages aforesaid as well as other objects and advantages may be achieved by the refuse bag holder illustrated in the drawings in which:

FIG. 1 is a view in perspective of the refuse bag holder with a decorative cover applied thereto;

FIG. 2 is a side elevational view of the refuse bag holder frame without the cover illustrated in FIG. 1;

FIG. 3 is an end elevational view of the refuse bag holder frame without the cover applied thereto;

FIG. 4 is a top plan view of the refuse'bag holder frame without the cover applied thereto;

FIG. 5 is a view in perspective of the refuse bag holder frame without the cover illustrating the foot treadle in a depressed position showing the closure means opened to admit refuse to the bottom of the bag;

FIG. 6 is a view in perspective of the refuse bag holder frame without the cover with the foot treadle in the resting or up position with the clinching means engaged to the bag closing the same; and

" and bag lifting mechanism.

Referring now to the drawings in detail, the refuse bag holder comprises a self-standing frame 1 1 defined by a pair of generally

erect U-shaped members

12,13 each having a pair of radially inwardly directed

offsets

14,15 and 16,17 respectively. The

frames

12,13 are joined together at the top by a circular refuse bag support 18 attached to the terminal ends of the

respective offsets

14,15 and 16,17. While the refuse hag sup port 18 is shown and described as circular, it may take any convenient open configuration. The support 18 comprises a relatively thin, upstanding flange preferably, but not neces sarily, coated with some friction-generating material such as rubber or one of a wide variety of well-known plastics which tend to frictionally engage other plastics, usually employed in the fabrication of plastic refuse bags.

The frame 11 is provided with

feet

19, 19, 19, 19 attached to and generally depending from the bottoms of the respective U-shaped

members

12,13. The feet 19 space the bottom

horizontal portions

20,21 of the U-shaped

members

12,13 from the floor.

A pair of opposed, upwardly extending, cinching

members

22,23 each are pivotally engaged to and across the bottom

horizontal portions

20,21 of the

respective U-shaped members

12,13 of the frame 11.

Cinching member 22 comprises a pair of spaced apart, generally parallel, upwardly extending

rods

24,25 each pivotally engaged at its bottom respectively to both

horizontal portions

20,21 of

members

12,13 by means of

pivot pins

26,27. The

rods

24,25 extend upwardly to a position beneath the refuse bag support 18 to merge with integral, generally radially inwardly extending

offsets

28,29. The

offsets

28,29

merge at an apex 30.

Cinching member 22 is provided with

lever legs

31,32 at the bottom of rods'24,25 respectively. The

lever legs

31,32 extend from

pivot points

26,27 to pivotally engage cinching member Cinching member 23 is similar in construction to cinching member 22 and comprises a pair of spaced apart, generally parallel, upwardly extending

rods

33,34 pivotally engaged at their bottoms respectively to the bottom

horizontal portions

20,21 of

U-shaped frames

12,13 by means of

pivot pins

35,36. The

rods

33,34 extend upwardly to a position beneath the refuse bag support 18 to integral, generally radially inwardly extending

offsets

37,38. The

offsets

37,38 merge at an apex 39.

Cinching member 23 is provided with a pair of

lever legs

40,41 at the bottom of

rods

33,34. The

lever legs

40,41 extend toward and past the ends of

lever legs

31,32 respectively of cinching member 22. The

respective lever legs

31,40 and 32,41 are slidably and pivotally engaged at

slide links

42,43 respectively.

Lever legs

40,41 extend beyond the

slide links

42,43 and are joined by an integral crossmember 44 to define a foot treadle.

Springs 45,45 are engaged between

rods

24,25 of cinching member 22 and opposed portions of U-shaped frame member 12. Springs 46,46, are engaged between

rods

33,34 of cinching member 23 and opposed portions of U-shaped frame member 13. The

springs

45,45 and 46,46 normally urge the

respective apexes

30,39 of cinching

members

22,23 toward each other when initially in overlapping relationship.

The

apexes

30,39 are adapted to cinch the refuse bag 47 beneath its open top, which is secured to support 18, thereby trapping refuse 48 collected in the bottom thereof. The

apexes

30,39 overlap when the cinching means are disengaged from the bag 47. The bag 47 therefore depends between the

offsets

28,29 and 37,38 of the opposed cinching

members

22,23. The

apexes

30,39 are in an overlapping position. When the cinching

members

22,23 are pivoted toward each other, the

passage defined by thesaid offsets and apexes opens to permit It is preferable that the

apexes

30,39 be generally parallel to each other and horizontal. It is also preferable that the

apexes

30,39, as they converge, define a circle of ever-decreasing radius until the apexes crush the bag 47 to effect a complete closure. Nevertheless, any cinching means of the character described will suffice even though the apexes portions are not absolutely parallel, and indeed may tend to cross. The particular configuration of the apexes should be determined by the crushing characteristics of the bag 47. Generally, the apexes will have a small radius.

The cinching

members

22,23 are operated by means of the crossmember 44 which defines a foot treadle. When the foot treadle 44 is depressed,

lever legs

40,41 depress, depressing the slide links 42,43. This in turn depresses

lever legs

31,32 of cinching member 22. The slide links 42,43 comprise elongated slots through which a pin 49 extends. Thus, the slide links 42,43 permit not only pivotal movement of the lever legs of the respective cinching members, but also some translational movement with respect thereto and necessary because of the fact that no translational movement is permitted at pivot pins 26,27 and 35,36.

Depression of the foot treadle 44 causes the

respective cinching members

22,23 to converge. However, since the

apexes

30,39 normally overlap, the said apexes diverge, thereby increasing the opening for the bag 47. Conversely, release of the foot treadle 44 permits the cinching

members

22,23 to diverge under the influence of

springs

45,45 and 46,46. The

apexes

30,39 however, converge to cinch the bag 47 therebetween to effect a closure.

Frequently, it is advantageous to relieve the weight of refuse collected in the bottom of the bag 47 during cinching so as to make the' cinching movement more efficient. Thus, a floor or bar may be provided at the bottom of the bag, which rises as the

apexes

30,39 converge and falls as the

apexes

30,39 diverge. Such a floor may be created by means of a rod 50 extending between and across the slide links 42,43. Obviously, a flat floor may be attached to the bar 50 if desired. Since the pivot pins 49 of the

respective slide links

42,43 rise and fall with convergence and divergence of the cinching

members

22,23, the pressure of the refuse in the bag 47 may be relieved upon closure.

In order to give the refuse bag holder a neat, compact appearance, a cover 51 may be provided which slides downwardly over the frame 11. The cover 51 comprises four

rectangular walls

52,52, etc. and a top 53 having an opening 54 therein to conform to the bag support 18. ln addition, one of the walls 52 terminates short of the floor in order to produce an opening 55 for the foot treadle 44.

Positive stops 56,56 may be employed across the

respective frame members

12,13 to limit the extent of divergent movement of the cinching

members

22,23. The position and nature of the stops 56 is a matter of choice although the function thereof is of value.

The foregoing description is merely intended to illustrate an embodiment of the invention. The component parts have been shown and described. They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper substitutes for the said components and may have actually been known or invented before the present invention.
