TECHNICAL FIELD
This invention relates generally to trash receptacles, and more particularly to devices for supporting trash bags and maintaining openings at the upper ends thereof for receiving waste.
BACKGROUND AND SUMMARY OF THE INVENTION
Traditional waste receptacles comprise an outer structure such as a can or basket and a trash bag set inside the outer structure through an opening in the top thereof. The open upper end of the trash bag is generally stretched and folded over the upper edge of the outer container, and a tie or knot is sometimes placed in any extra bag material to tighten the bag's seal around the container. When items are placed into the bag and the weight within the bag begins to pull the top of the bag down the seal is easily loosened or lost causing the top of the bag to collapse and fall into the container. Re-fastening the top of the bag around the container may or may not occur before more items are put into the container resulting in an undesirable outcome.
After the trash bag is filled it must be lifted out of the container through the opening in the top of the container. Items inside the trash bag often compact together thereby stretching the sides of the trash bag thereby preventing the filled bag from being easily lifted through the opening at the top of the container. Often a bag will tear when an item is pushing outward against the bag causing the bag to catch on or below the surface of the container opening as the filled bag is being removed from the container. If the filled bag is successfully lifted and removed from the container without tearing or spilling trash deposited therein, the filled bag must then be transported to a trash collection site which may be a large waste collection container, a dumpster, or the like. The task of transporting the filled trash bag be difficult for some persons as not everyone has the strength or ability or desire to lift a filled trash bag and carry it to a larger waste collection container.
Alternatively, trash bags are not always placed in a container. For example, although a lawn and leaf trash bag may stand on its own it is usually difficult to keep the top of the bag open while placing trash therein. After the bag is filled the top must be folder over and the filled bag must be transported to a designated area for pickup or disposal. Although lawn clippings, leaves, and the like which are generally deposited into lawn and leaf trash bags are light in weight a bag filled with such materials is generally bulky in size and the quantity of trash filling the bag can have a substantial weight thereby making the filled bag cumbersome and difficult to transport.
The present invention comprises an devices for supporting trash bags which overcome the foregoing and other difficulties which have long since characterized the prior art. In accordance with specific aspects of the invention a trash bag supporting device comprises an open frame having a bag support ring incorporated thereon. A trash bag is extended through the ring, the upper perimeter of the bag is folded over the ring, and a pressure ring is placed over the bag and support ring to maintain the bag in engagement with the frame. Once the bag is filled the pressure ring is removed and the upper perimeter of the bag may be pulled beneath the support ring thereby enabling the bag to be removed without requiring the bag be lifted through the confined area of the support ring. The bag is easily removed from the frame without the risk of tearing and without requiring the strength to lift a heavy filled trash bag.
In accordance with specific aspects of one embodiment of the invention the frame comprises an upper portion and a lower portion which are adjustably coupled together. The upper portion telescopes between different pre-defined positions enabling the apparatus to accommodate various sizes of trash bags. A lid engages the pressure ring and provides a cover over the trash bag. The lower portion of the frame may comprise a set of wheels thereby enabling the apparatus to be transported with the trash bag supported therein thereby facilitating transport of a filled trash bag to a larger waste collection container or location.
Other embodiments of the invention comprise otherwise conventional trash bag receiving containers that are equipped with the support ring and the pressure ring of the present invention. A lid may be engaged with the interior surface of the pressure ring to prevent vermin from entering and odors from escaping from trash bags supported in accordance with the invention.

DETAILED DESCRIPTION
Referring now to the Drawings, and particularly to FIG. 1 thereof, there is shown a trash bag supporting apparatus 10 comprising one embodiment of the present invention. The apparatus comprises an open frame 12 having an upper portion 14 and a lower portion 16. The upper portion 14 comprises an upper support wall 18 having a support ring 20 extending perpendicularly therefrom for receiving and supporting a trash bag T. The lower portion 16 comprises a lower support wall 22 and a base 24 extending perpendicularly therefrom for further supporting the trash bag T. The upper portion 12 is adjustably fastened on the lower portion 14 and telescopes vertically in relation thereto such that the frame 12 may be adjusted to different heights to accommodate various sizes of trash bags. Wheels 26 secured to the lower portion 16 enable the apparatus 10 to be moved while supporting the trash bag T.
After placing a trash bag T through the support ring 20 the upper perimeter of the bag T is folded over the support ring 20 and a pressure ring 28 is then placed thereover and pressed downward until the pressure ring 28 seats within the support ring 20. The pressure ring 28 thereafter maintains the trash bag T in mating engagement with the support ring 20 and thus the apparatus 10. A lid 30 provides a covering over the top of the trash bag T and provides further downward pressure on the pressure ring 28 and support ring 20. To remove the trash bag T from the apparatus 10 the pressure ring 28 is lifted from the support ring 20, the upper perimeter of the bag T is lowered through the support ring 20, and the bag T is removed by pulling the bag T horizontally outward from within the frame 12.
Referring to FIG. 2, there is shown an exploded perspective view of the trash bag supporting apparatus 10. The upper portion 14 and the lower portion 16 of the frame 12 are adjustably fastened by a bracket 34 secured to the lower support wall 22 by a threaded fastener 36 extending through an aperture 38 in the lower support wall 22. The upper support wall 18 telescopes vertically in relation to the lower support wall 22 and nests over the lower support wall 22 when the frame 12 is assembled together for receiving a trash bag therein. Threaded fasteners 40 extend through one of a plurality of sets of apertures 42a and 42b, through the apertures 44 in the lower support wall 22 and into threaded engagement with the bracket 34. The plurality of sets of apertures 42a and 42b facilitate securing the upper portion 14 at different heights in relation to the lower portion 18 in order for the frame 12 to accommodate various sizes of trash bags.
The upper portion comprises an upper lip 46 beneath the support ring 20 for providing horizontal support to a trash bag within the frame 12 and also for securing the upper portion 14 to the lower portion 16 in a storage configuration as will be discussed in conjunction with FIG. 4. The lower portion 16 comprises a lower lip 48 on the base 24 for providing horizontal support to a trash bag within the frame 12 and also for securing the upper portion 14 to the lower portion 16 in a storage configuration as will be discussed in conjunction with FIG. 4.
A handle 50 is provided at the upper end of the upper portion 14 and is supported by a dowel 52 extending therethough which is in turn secured by a nut 56 or other suitable fastening means known to those skilled in the art. The wheels 26 are secured to the lower portion 16 by an axle pin 60 and fasteners 62, or other suitable fastening means known to those skilled in the art.
