Description
Field of the Invention
The following invention relates generally to frames used in supporting flexible trash bags. More particularly, the essence of the invention is to provide a frame which circumscribes and supports, an opening of a trash bag or the like in a reliable and secure manner. A further component comprising a stand is included which allows the trash bag opening frame to be free standing.
Background of the Invention
A common problem exists with respect to flexible trash bags in maintaining the bag in an open position for subsequent filling. When the bag is used as a liner and conforms to the inner contour of a trash can, the opening, even if folded over the top edge of the supporting trash can, has a tendancy to collapse within the trash can. This is because the liner is influenced through friction and by entrainment with the debris which passes into the bag liner.
When the bag liner is used without the assistance of a supporting container, the problem is exacerbated because the bag has no memory which retains the open shape. Thus, an assistant is required to hold the bag in an open position or one of a person's hands is used in an attempt to open the bag to receive contents therewithin. Even with an assistant, the bag opening does not approach a cross sectional area which conveniently facilitates the through passage of material because the bag has not been constrained in its optimal widest open position.
The prior art is fairly rich in attempts to overcome the above stated deficiencies. Some of these patents have inherent dificulties in that they are somewhat dated. Thus, their structure cannot conform to the currently available bags now on the market. Mainly, these holders provide reusable bags that are custom contoured for the holder.
Other of these prior art devices include removeable clips or the equivalent which, while somewhat effective provides loose pieces which tend to get lost.
Another set of known prior art attempts includes a clamping type mechanism that is formed with the bag frame, and are therefore based on the same concept as the instant invention. These prior art attempts are deficient in at least one of the following areas: the ability to quickly fasten a removeable bag to an associated frame, the ability to securely fasten same, and the ability to secure the bag in such a manner that it does not interfere with the subsequent utilization of the thus supported bag.
Summary of the Invention
The instant invention is distinguished over the known prior art in that the components that fix the bag to the associated frame are integrally formed as a single device thereby precluding the possibility of losing the fastening instrumentalities associated with the frame.
In addition, the device according to the instant invention expeditiously and securely fastens a bag to the associated frame without the associated problem of interfering with the inherent function to be performed by the bag.
Essentially, the device embraces a hoop formed from a strip of material such as metal, configured as a closed loop. The loop supports a complimentally formed rim of resilient material such as wire at one or two points along the periphery of the hoop. The rim has a memory or biased resilience to cause it to press against the frame and hold the bag therebetween. One edge of the hoop supports a lip having a feathered edge which is remote from a handle so that when the handle is grasped, the feathered edge can be placed on a surface and readily admit debris into the bag.
The rim and the hoop frame collectively grasp a trash bag which is first placed within both the hoop and the rim. The open edges defining the mouth of the bag are looped over the wire rim and underneath the rim inside the hoop so that a trash bag is securely attached. To further enhance the retention of the bag with respect to the frame, the rim is also captured by a recess on the feathered edge lip to firmly fix the rim with respect to the hoop and therefore the bag.
In another form of the invention, the hand held portion can be affixed to a free standing instrumentatility which includes at least one downwardly extending member which holds the hoop frame and rim in a horizontal position elevated above a support surface. The vertically downwardly extending support member attaches to a base configured for stability. The base may also include a supporting axle having wheels for ease in transport.
Another version contemplates providing a frame formed from a pair of vertically upstanding support members communicating the base to the hoop and rim frame.
When the hoop assembly includes a support stand, the trash bag captured by the hoop and the rim can be used as a free standing waste basket. Alternatively, the stand assembly can be tipped on its side so that the feathered edge contacts a support surface and debris can be swept within the bag since one's hands are free from holding the hoop handle.
Objects of the Invention
Accordingly, it is a primary object of this invention to provide a novel and useful appliance to facilitate the use of trash bags.
A further object of this invention is to provide a device as characterized above which engages the mouth area of a conventional disposeable, flexible, trash bag in fixed relationship to a circumscribing frame so as to reliably enable use of the bag liner.
A further object of this invention contemplates providing a device as characterized above wherein a retaining rim is associated with a hoop collectively forming a frame which captures the bag securely for positive retention and support of the bag.
A further object of this invention contemplates providing a device as characterized above which can either be hand held or supported from a base to be free standing so as to provide a multiplicity of uses.
It is yet a further object of this invention to provide a device as characterized above wherein one edge of the hoop frame, remote from a hand holding area, includes a feathered edge to facilitate placement of the edge against a support surface to expedite passage of debris within to the trash bag.
It is yet a further object of this invention to provide a device as characterized above which is extremely durable in construction, safe to use, lends itself to economies of scale for mass production, is light weight and reliably secures a conventional garbage bag for the attendant purposes.
It is a further object to provide a device as characterized above which is so fabricated that when disassembled the elements are oriented in a substantially flat plane for convenient shipping.
These and other objects will be made manifest when considering the following detailed specification taken in conjunction with the appended drawing figures wherein there has been provided a means for removeably fastening a conventional trash bag mouth to a frame which retains the mouth, a handle on one side of the frame, a feathered edge on a remote side of the frame, and optionally, a support stand to hold the frame in an elevated horizontal position above the supporting surface.

Brief Description of the Preferred Embodiment
Referring to the drawings now, wherein like reference numerals refer to like parts throughout the various drawing figures, reference numeral 10 is directed to the trash bag holder according to the present invention.
In its essence, the trash bag holder 10 includes a hoop/rim type frame 50 or 60, which may be used independently or in combination with a stand assembly 20 or 20', 30 or 40. The hoop and frame assembly will first be discussed, particularly with reference to FIG. 5B.
As shown, a trash bag TB is fastened to the frame 50 by means of first taking the mouth opening of the trash bag and threading it within the interior of the frame. The peripheral edge E denoting the trash bag mouth is looped over a wire rim 54 and threaded between the wire rim 54 and a hoop 52. Contents within the bag provide a downward force pinching the rim 54 against the hoop 52 and in conjunction with other retention means, hold the bag in place securely.
More particularly, and with reference to FIGS. 1, 2, 7, 8 and 10 specific details with respect to the hoop and rim frame can now be explored. Basically, the hoop 52 is formed from a piece of material, preferrably metal, having rectangular cross section and formed so as to be a four sided hoop. Note a three sided, triangular version would also work acceptably. Ends of the hoop are placed in mating registry and fixed together by spot welding or riveting (not shown). The free ends of the hoop frame extend outwardly from a medial portion of an outside wall of one frame side and are received within a handle 58 (FIG. 3).
A side of the hoop frame 52 remote from the handle 58 supports a lip 56 along its length and about corners thereof. The lip 56 has a feathered edge 56a (FIG. 5A) which facilitates through passage of debris within the hoop. More particularly, the feathered edge 56a, forming a part of lip 56 includes an arcuate portion 56b which retains the wire rim 54. A linear portion 56c is attached to the hoop frame 52 so that the feathered edge 56a can be free standing. Note the presence of the notch 56d which serves as an abutment shoulder upon which the rim 54 resides.
The rim 54 is formed from a resilient material, preferrably wire, having a configuration complimental to that of the hoop 52 so that it overlies the hoop 52 as shown in FIG. 7. FIG. 3 details the means by which the wire rim 54 and hoop 52 attach to a sleeve 58 defining a handle. The free ends of both the hoop 52 and rim 54 terminate within the handle 58 and are retained therewithin by means of a screw 59 which passes between the free ends of the hoop 52 wedging them apart and against the sleeve 58. The rim 54 can optionally be track welded onto a top surface of the hoop 52 so that the remainder of the rim 54 is separable by biasing the rim 54 away from the hoop 52 to allow the trash bag TB to be placed as shown in FIG. 5B and FIG. 7. Once the trash bag TB has been placed as discussed, the edge of the rim 54 remote from the handle sleeve 58 is snapped into place by depressing the rim 54 into the lip 56.
A different form of hoop rim frame arrangement is shown with respect to reference numeral 60 illustrated in FIG. 8. In this instance, the rim 64 is formed from two substantially U shaped pieces capable of articulation about sides of the frame 52. The rim 64 is not tack welded adjacent the handle 58, but is attached to the side edges of the hoop 52 substantially medially between the handle side 53 and the lip 56.
More particularly, a clip 62 (FIG. 8A) attaches the wire rim 64 in the following manner. A clip 62 having substantially U shaped configuration including a short leg 62a, a long leg 62b and a bight portion 62c straddles the frame hoop 52 from a bottom edge thereof and is frictionally retained thereon by means of the spring resilience of the clip 62. The long leg 62b extends upwardly and within the periphery of the hoop 52 and includes an opening 62d within which a free end 64a of the rim is rotatably placed. Thus, the two U shaped sections of rim 64 move in the direction of the arrows A and each rim segment is retained in a closed position either by the lip 56 or by a tang 66 adjacent the handle 58.
As shown in the various drawing figures, the handle 58 can be of various lengths or configurations. The handle 58 can have a terminal portion adjacent its connection to the hoop ends 52 and rim 54 that is rectangular in section (FIG. 10), paralleling the configuration of the hoop and rim portion that it overlies. Specifically, FIG. 10 shows an elongate handle arrangement which is squared adjacent the connection to the hoop 52 and rim 54. The handle is long enough so that the hoop and rim frame assembly reaches the ground easily and can be used independently of any other instrumentality other than the trash bag TB. In addition, however, the hoop/frame arrangement can be associated with a support stand so that the device can serve as a waste basket, for example, in a manner now to be defined.
More particularly, and with reference to FIGS. 2 and 4 for example, the handle 58 can be integrally formed within a support member 34a defined simply as an upper horizontal portion of a vertical support member 34. The vertical support member 34 (FIG. 4) includes an internal spring 58a of "U" shaped configuration that supports a detent 58b passing through a hole 2 in a vertical sleeve 32. Thus, by depressing the detent 58b the member 34 can be raised or lowered changing the height of the hoop and frame assembly.
With respect to FIG. 1, a vertical support member 34, integral with the horizontal upper portion 34a telescopes within the sleeve 32 so the hoop and rim can be adjusted at different vertical elevations. By providing a plurality of holes 2 along the length of the sleeve 32 and providing the "U" shaped spring 58a within the support member 34, the elevation of the hoop/rim arrangement can be alered so that different vertical elevations can be afforded the hoop while the hoop remains in a substantially horizontal plane.
The lowermost end of the sleeve 32 terminates in a substantially horizontally extending base leg 36 which as shown in FIG. 2 extends below a central portion of the hoop to provide stability. The base leg 36 in turn communicates with a base transverse leg 4 disposed at right angles with respect to an end 39 of the base leg 36. The detail for this structure is shown at FIG. 1A. More particularly, the base leg 36 connects to the transverse leg 4 by means of a bolt 6 passing through a wall of the leg 4 and extending into the interior of the base leg 36. The bolt 6 is secured thereto by means of a nut 38 fixed on the interior of the base leg 36 by means of inwardly extending prongs 37 made by distressing the side wall portions of the base leg 36 inwardly to provide prongs 37 that retain the nut from translation outside of the base leg 36. As shown in FIG. 2, the transverse leg 4 has feet 8 at extremities thereof to prevent marring of the support surface.
Alternatively, and with respect to FIGS. 6A and 6B, the free end of the base leg 36 can lead to a transverse leg 4 that supports wheels W thereon. FIG. 6A shows that the base leg 36 is linear with respect to its extension to the transverse leg 4, but that the bend in the tubing between the sleeve 32 and the base leg 36 is less than 90 degrees to offset the incline in support 36 dependent on the size of wheels W. This angle can be varied as desired. In addition, FIG. 6B has two variations of free ends of the base leg 36 in which 36a shows a possible serpentine configuration with a free end substantially parallel to the major aspect to the base leg 36, or alternatively a free end 36b which is upwardly angulated.
With respect to the wheels W, FIG. 9 shows a construction detail for the free ends of the transverse leg 4 as it supports the wheels W. As shown, a bolt 6 attaches the wheel W to a nut 38 fixed with the tubing of the transverse leg 4. The transverse leg 4 includes prongs 37 formed by distressing and bending in portions of the transverse leg 4. The wheel W itself is supported by means of a fender 12 of substantially "U" shaped configuration. Inboard fender leg 12b, an outboard fender leg 12c and a bight portion 12a collectively straddle the wheel W. Holes 12d are provided to allow the through passage of the bolt 6 therethrough.
FIGS. 11 and 12 detail another possible embodiment 48 with respect to the support stand. As shown, this stand favors utilization with the hoop/rim version 60 including two rim sections 64. In this eventuality, a pair of vertical support members 42 extend downwardly from side edges of the hoop 52 proximate to where the clip 62 attaches the rim 64 to the hoop frame 62. A pair of nuts and bolts 42a attach the upper horizontal portion 34a to the frame 52 and the vertical support member 34 and sleeve 32 include a base leg 36 so that as shown FIG. 12, two substantially "L" shaped support members carry the hoop/frame in an elevated horizontal position. The base leg 36 include a leg 46 interconnecting the two "L" shaped support members at ends of legs 36 for stability.
Note that no component discussed above has substantial "thickness", three dimensionally. Thus, when disassembled, a kit is provided which can be shipped in a relatively thin container.
Having thus described the invention it should be apparent that the numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention set forth herein above and defined herein below in the claims.
