Such devices are shown in US. Pats., No. 310,101 to Wagner of Dec. 30, 1884; No. 611,498 to Lyon of Sept. 27, 1898; No. 1,322,445 to Hyer of Nov. 18, 1919; and No. 3,491,973 to Hartbauer of Jan. 27, 1970. They do not lend themselves to low cost high production, raise problems of shipment and storage, and are not foldable or usable both indoors and outdoors.

Another approach to the problem of holding open the limp end of a limp garbage, trash or litter bag of thin plastic is found in the type of device which is made of low cost light material such as wire or strip metal. A hoop, supported by rods stuck in the ground, is taught in US. Pats., No. 3,532,314 to Vosbikian of Oct. 6, 1970 and No. 3,604,677 to Gits of Sept. 14, 1971, but these devices are useful only outdoors and have no base for use indoors. Bag holders made of similar material which are usable only indoors and not outdoors, and which have no folding capability, are disclosed in US. Pats., No. 3,576,306 to Grebon of Apr. 27, 1971, and No. 3,598,350 to Kaufman of Aug. 10, 1971.

Another bag holder, usable with small garbage bags, is taught in U.S. Pat. No. 3,614,042 to Jensen of Oct. 19, 1971, wherein a table-like pivoted framework is suggested for use indoors on a table and of a size which would fit in a package of the garbage bags.

SUMMARY OF THE INVENTION In this invention, the bag holder is foldable into a relatively flat, compact package for shipment and storage because it is formed from a vertical standard, a horizontal planar upper bag-holding frame and a horizontal planar lower base-forming frame, all of light weight rod, or wire, material such as metal, the frame being foldable flatwise against the standard. The holder is unique in that the lower frame includes prongs and can be folded into position in extension of the standard and thrust into the ground for outdoor use, the upper frame being thereby at a higher level to accommodate larger trash or litter bags.

The upper frame is preferably circular with a tail which fits in the channel groove of the single standard, and the standard includes a pair of locking recesses in the lower terminal end which receive the upper frame. A novel locking means is provided consisting of a plate with a U-shaped slot and an arcuate cam surface, so that the lower frame is a lever for snapping the upper frame out of folded position and so that the lower frame is lockable in both horizontal and vertical extended positions.

DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in the drawing, the bag holder 20, of the invention, is preferably formed of relatively low cost, light weight rod, wire or strip material, such as the steel 21, or other metal, or structurally equivalent material.

The bag holder 20 includes vertical standard means 22, preferably in the form of a single upright metal standard 23 of channel cross section, having an upper end 24 with

holes

25 and 26 in the

side walls

27 and 28 and a recess 29 in the rear wall 31. Standard 23 includes a lower end 32, in which the

side walls

27 and 28 are pinched toward each other at 33 and 34 to receive a locking plate, there being a slot 35 in the rear wall for the plate and a pair of

recesses

36 and 37 in the terminal ends of the

side walls

27 and 28 to receive the upper frame, as shown in FIGS. 2 and 5, or to receive the lower frame as shown in FIGS. 1 and 3.

The upper frame means 41 is flat, planar, light weight and preferably in the form of a closed circular loop forming a frame 42, made of aluminum of round cross section about one-quarter of an inch in diameter, and having an integral tail 43 normal thereto. As shown, the upper, flat, planar frame 42 is approximately the diameter of the open end 44 of a limp, thin-walled, plastic trash bag, or liner, 45 so that the end 44 may be draped thereover and supported while the bag is being filled. When the frame 42 is folded, as in FIG. 2, the tail 43 projects slightly from recess 29 of standard 23, but when turned through an angle of 270, the tail rests in the channel to maintain the frame in horizontal bagholding position. The tail 43 thus cooperates with the upper end 24 of the channel to form stop means 46 which normally supports the upper frame 42 horizontally. Preferably, the aluminum, or other material, 21, of which frame 42 is made, is resilient and slightly deformable so that in folded position the free end 47 of the loop can be stretched over the terminal end 32 of standard 23 to snap into the

recesses

36 and 37, as shown in FIG. 5.

The lower frame means 51 is also flat, planar, light weight and may be formed of the same round cross section rod-like material 21 as the upper frame 42. The frame means 51 comprises a frame 52 which is bifurcated into a pair of oppositely disposed

legs

53 and 54 which define a triangle having its apex 55 welded at 56 to the cam locking plate 57, and having an integral cross brace 58 intermediate thereof, the legs terminating in prong means 59, comprising the parallel

free terminal ends

61 and 62 which are blunt, chisel-pointed for insertion into the ground.

The locking means 71 includes the cam and locking plate 57 which is provided with a U-shaped slot 72 and a recess 73 for weldment to the apex 55 of lower frame 52, the plate being pivotable on a pivot pin 74, passing through

holes

75 and 76 in

side walls

27 and 28 of the pinched

portions

33 and 34, which pivot pin is conveniently a wing nut set screw 77, although the device will remain in selected positions by spring bias even if not screw tightened by set screw 77. As shown in FIG. 1,

the

legs

53 and 54, when horizontal, constitute a pair of oppositely disposed, side frame elements sufficiently spaced apart to firmly support the standard vertically on the floor of a room, while the open end of a bag is supported in the upper frame 42 for filling. The standard 23 is of predetermined length, substantially equal to the length of the bag 45, to hold the conventional indoor type bag 45 at the correct height for filling. The resilient deformable looped upper frame 42, as shown in FIG. 2, is of a cross-dimension substantially equal to the length, or height, of standard 23 to be snap received, and cam unseated, from locking

recesses

36 and 37. The lower frame and prong means are so dimensioned that when the cross brace is used as a foot rest and the prongs inserted into the ground to the brace, the upper frame will be at the correct height to support the larger outdoor type bag.

In operation, it will be seen that the bag holder 20 folds compactly with upper frame 42 flatwise, in parallelism with the rear of standard 23, and lower frame 52 flatwise, in parallelism with the front of standard 23. As shown in FIG. 5, the upper frame is locked in position by being snapped into the

recesses

36 and 37, and the lower frame is locked in position because the pivot pin 74 is at 78, intermediate of the length of slot 72 with the resilient frame 42 pressing on the arcuate exterior cam-like surface 79 of plate 57 to spring press the lower frame against the standard.

A novel feature of the invention is that to unfold the device, a slight pressure on the

prongs

61 or 62 applies leverage through cam face 79 to unseat the loop frame 42 from the

recesses

36 and 37, whereupon the upper frame may be pivoted 270 to bag-holding position.

The lower frame may be placed in indoor baseforming position by straddling the portion of lower frame 52 adjacent the plate 57 by the

recesses

36 and 37 in the end of the standard 23, and permitting the pivot pin to enter the end 81 of U-shaped slot 72, as in FIG. 1, the device then being fixed in position. The screw 77 is preferably then tightened.

To achieve outdoor position, the lower frame is unfolded into extension of standard 23, as in FIG. 3, the

recesses

36 and 37 are straddled on the adjacent portion of the lower frame, and the pivot pin permitted to enter the end 82 of U-shaped slot 72. The screw 77 is then tightened, the device thrust into the ground and used to support a larger sized bag outdoors.

As shown in FIG. 1A, clamping means 83 may be used, wherein the upper frame 42 includes an annular peripheral groove 84 for a resilient deformable clamping ring 85 of rubber, plastic, metal, or the like, to grip the bag 45 therebetween.

Alternatively, as shown in FIG. 1B, the clamping means 83 may include an upper frame 42 of magnetizable metal 86, such as steel, and at least one permanent bar magnet 87 for clamping the bag 45 therebetween.

A cover 91 is provided which is also light weight and comprises a pair of

concentric metal rings

92 and 93, ring 92 fitting closely within ring 93, with limp plastic material 94, such as a plastic bag, clamped therebetween and tautly stretched thereacross in the manner of a drum head. The plastic 94 is wrapped around the outside of the outer ring 93 and then extends between the clamp rings to cover up the steel strip material of the rings. The cover 91 can be used in the manner of a scoop to pick up leaves outdoors, and it forms a closure for the trash bag held in the holder to lock in odors and prevent access by insects. Preferably, the diameter of

rings

92 and 93 is slightly greater than the diameter of the upper frame 42 so that a relatively tight closure is obtained. When folded, as in FIG. 2, the holder fits within the cover for protection and shipment, the area enclosed by the rings being substantially equal to the area of the upper frame, regardless of the configurations thereof.
