This invention relates to a sturdy bag clip for supporting trash bags.
The invention will be described in its preferred embodiment of a clip 50 for a wire rack for use with recycling trash bags 100 such as are utilized in consumer collection of leaves and other lawn debris (see
Multiple clips are typically utilized to hold a trash bag 100 to the rack. Each clip 50 shown has contact surfaces to hold the paper or plastic material 100 to the rack. The preferred bags typically are paper. Upon insertion of the material into the clip 50, the compression action of the sides of the clip retains such material within the clip without the necessity of further consumer action. The linear contact length 120 of an individual clip 50 serves to retain the bag material within such clip 50 by a compression action. The cooperation of adjoining clips 50 reduces the separation of the material 100 from any individual clip perpendicular to the axis thereof. Preferably, the initial contact with the clip 50 is spaced from the tip of the clip to allow for preliminary guidance of the bag material into an opening 80 and through such opening into the body of the clip 50. The distance between the sides 110 of the clip allows for the physical contact between the consumer's fingers and the bag material being associated with the wire rack within any individual clip. This guides the consumer into proper use of the wire rack. This is further aided by the top frame 40 of the wire rack, which frame separates the user's fingers at the top of the adjoining motion.
One clip rack would serve to hold the bag in place; two clips would orient the bag, for example in respect to an opening therein; three clips would define a planar triangular opening; while four clips would define a rectangular opening. The rack, thus, cooperates with the clip to hold the bag in position.
The rack 10 shown is a wire rack having a side 11, a base 13, and a top 14 (
The side 11 is designed to retain the top 14 of the wire rack 10 a spaced distance from the ground substantially parallel thereto. In the preferred embodiment disclosed, this is accomplished by supporting the top 14 (later described) a fixed distance from the ground which distance is substantially equal to the length of the open trash bag to be utilized with the wire rack from the base 13. A ratio of 90-110% could be utilized if suitable for this purpose.
The side 11 is preferably simple in overall shape and mirror imaged about its centerline in order to lower the manufacturing costs for the rack by minimizing the number of construction jigs as well as easing the assembly of the rack. It is preferred that the side 11 be formed out of a unitary piece of bent rod, both to facilitate manufacture and in The first upright 21 and second upright 22 are located substantially in a single plane with the top portion 23 and bottom portion 24 slightly offset therefrom (see
In the preferred embodiment disclosed, the top and bottom portions 23, 24 extend off the two ends of the uprights at a backward angle (approximately 25° shown in
The support for the top 14 and base 13 in addition uses top stop pieces 25, 26 extending between upright 21 and upright 22 substantially parallel to the top portion 23 and bottom portion 24 slightly spaced therefrom respectively. These stop pieces 25, 26 form ledges on which the top 14 and base 13 rest in their extended use position, allowing a cantilever-type physical support between the single side 11 and such top 14 and base 13 (see
The dimensions of the side 11 are chosen in view of the bag to be utilized with the rack (i.e., the length of the uprights 21, 22 aid to define the operational height of the rack 10 while the top portion 23 and bottom portion 24 define the operational width of the rack 10).
The base 13 serves to physically support the side 11 (and remainder of the rack 10) to the ground.
The preferred base 13 consists of the two parallel sides 30, 31 joined by an end cross wire piece 35. An alternative base would be two longitudinal extensions of the sides 21, 22 of the rack 10 for use as prongs for pressing into the grass soil with which the alternative rack 10 is to be utilized (see
The primary purpose of the parallel sides is to provide a physical support for the rack 10 as well as connecting the end cross wire piece to the side 11 of the rack 10. In the preferred embodiment shown, the base 13 connection is provided by tip end loops having a diameter substantially equal to that of the bottom portion 24 of the side 11 (see the tip end loop 32 in
The use of two parallel sides 30, 31 integral with the end cross wire piece 35 is again preferred due to the structural simplicity and physical strength of the design. It also provides some external support for the trash bag utilized with the rack. The identity and nature of the cross piece 35 is not critical as long as this function is performed.
The top 14 serves to physically support the top of the trash bag 100 in addition to spacing the sides of such bag a certain distance apart. The top 14 also provides a handy fill opening for and physical protection of the open top of the trash bag 100.
The preferred top 14 disclosed includes a top frame 40 and bag clips 50. (The bag clips 50 provide the primary support for the bags to be utilized with the rack as later disclosed.)
The top frame 40 serves to provide the protected fill hole for the trash bag 100 in addition to providing the physical location of the bag clips 50. (The fill hole 41 in the top frame 40 provides for holding the opening for the trash bag 100 about its edges. The bag clips 50 retain the top of the trash bag to the top frame 40.)
The opening for the trash bag occurs because of the interconnection of the top, open end of the trash bag 100 to the bag clips 50. As the bag clips 50 are physically separated and spaced in respect to each other, they cooperate to retain the top of the trash bag open. The bag clips 50 thus serve to physically hold the material that forms the top walls of such bag in its proper, open position relative to the remainder of the bag rack 10.
Each bag clip 50 (shown in
In the preferred embodiment disclosed, the extending ends of the two portions cooperate to form an opening 80 to initially guide the top of the trash bag into its retention position in respect to the bag clips 50. The reason for this is that the portions 60, 70 themselves are designed to serve as a guide for the user's fingers (again typically forefinger and thumb) during the process of engaging the trash bag with the clips 50. This movement also inherently aligns the top of the bag with the bag clips 50. The distance between the portions is preferred to be ¼″ to ⅝″ to provide gripping between the user's fingers and the top of the bag between the portions 60, 70 of the rack (½″ further preferred). (An extension downwards is preferred for these bag clips 50 for ease of operation as well as providing an overweight release of the bag from the rack 10.)
At least one top end 61, 71 of the respective portions 60, 70 of the bag clips 50 serves to attach the bag clips 50 to the top 14 of the wire rack 10. In the preferred embodiment disclosed, this attachment is provided for the welding of the top end 61 of the clip 50 to the top frame 40. This welding securely connects the clip 50 to the side pieces 42, 43 against torsion forces as well as lateral and longitudinal forces.
In the embodiment disclosed, the portions 60, 70 are each a generally U-shaped piece having a top end 61, 71 respectively and a bottom loop 65, 75. The end locations 52 is spot welded to the top frame 40 to securely interconnect the bag clip 50 to the top 14 of the rack 10 (top frame 40 side piece 43 shown).
The bottoms 65, 75 of the portions 60, 70 are formed into an upright U-shape with two spaced sides 66 (76), 67 (77) and an outer end 68 (78).
The two spaced sides provide for a resilient reaction surface for the retention of the trash bag (later described). The spaced sides 66, 67 provide this reaction surface by forming two spaced substantially parallel contact lines with the spaced sides 76, 77 of the other portion 70. These contact lines hold the top of the trash bag to the rack 10 (as later set forth).
The outer end 68 of the portion 60 cooperates with the outer end 78 of the other portion 70 to form an opening 80 into which the material of the trash bag may be inserted by the consumer. In the preferred embodiment disclosed, the outer end 78 is slightly deflected from the plane of the two spaced sides 76-77. This facilitates the proper and instinctive location of the trash bag with the opening 80 of the bag clip 50. (One need not compensate for the central junction of an alternative opening formed by two angled surfaces; instead one merely pushes the top edge of the bag into the opening and picks up to engage the clip 50.) This one outer end deflection is thus preferred.
The main spaced sides of the portion 60, 70 of the bag clip 50 serve to retain the bag material in respect to the top frame 40 of the wire rack 10. The sides 76-77 of the portion 70 are parallel and substantially aligned with the spaced sides 66-67 of the portion 60. This forms two straight spaced friction lines of contact to retain the bag material in the clip 50 by a compression-type force. This reduces tearing by spreading out the forces while at the same time extending service life by eliminating the need to retention or realign the bag clip on use.
The outer end 78 of the portion 70 is spaced from the outer end 68 of the portion 60 so as to create an opening 80 for the insertion of the bag material into the bag clip 50 against the spring-like action of the two portions 60, 70 of such bag clip 50. This facilitates use by eliminating any complex threading of the bag material into the bag clip 50.
In the preferred embodiment disclosed in
In the preferred embodiment disclosed, the length of the bag clip 50 is within 1″ to 2″ preferred (some 1.7″ in length shown). The top of the bag clip 50 is within the preferred 0.4″ to 0.9″ wide (some 0.750″ in width shown). There is a 0.063″ to 0.250″ offset between the two non-aligned parts of the bag clip 50 (at 80) (0.125″ shown). The clip material is some 0.1″ to 0.075″ preferred in diameter (some 0.092″ shown). The outer end 78 of the portions 60, 70 is angled at substantially 25° for the last ¼″ of its length (some 15° to 35° preferred for the last 0.125″ to 0.350″ in length).
The dimensions of the wire rack should substantially match the height and width and length of the bag to be utilized with the rack 10. For example, a particular paper bag has an opening 12″ wide by 16″ deep by 35″ high (30 gallons). The 12″ would define the base 13 and top 14 dimensions of the rack, while the 16″ and 35″ would define the side dimensions.
It is preferred that the rack 10 have a height within the range of 12″ to 36″, a width within the range of 8″ to 20″, and a depth within the range of 5″ to 20″. It is further preferred that the dimensions of the rack 10 substantially match those of the bag. It is further preferred that the height of the top of the bag clips 50 be substantially equal or less than the height of the bag. This allows the bag itself to provide part of the support of the items within the trash bag.
To use the rack 10, one moves the top 14 and base 13 approximately 270° in respect to the plane of the side 11 of the rack 10. The base 13 is then placed on the ground. At this time, the trash bag to be utilized with the rack 10 is opened and its top edges are pulled into the bag clips 50, one clip at a time. The bag can then be filled through the bag opening 40. Upon the completion of filling the bag, one removes the bag from the rack 10, one clip at a time. The bagged material is then amenable to disposal. On completion of all bagging, the wire rack 10 is collapsed back into its compact storage position and put away for use at a later time.
With a large trash bag in the wire rack 10, the rack is being utilized for its intended purpose.
Although the invention has been described in its preferred embodiment with a certain degree of particularity, it is to be understood that numerous changes can be made without deviating from the invention as hereinafter claimed.
A bag clip could be utilized with both of its now symmetrical pieces welded to the top rod 40 (see 50A in
An example, extending a looping back of the tips of both portions 60, 70 of the bag clip 50 increases the friction exerted to the bag clip 50 on the bag (see extension in dotted lines 90 in
An additional example, the bag clips 50 can be utilized with differing racks. An example of such a rack is that contained in U.S. Pat. No. 5,303,889 or U.S. Pat. No. 5,014,944, the contents of which are included by reference. Other changes can also be made.
Other modifications are also possible.
