BACKGROUND OF THE INVENTION

1. Field of the Invention

Handle means for carrying one or more bags having loop handles. In particular, a handle comprising a rod with knobs having annular grooves at each end for receiving grocery bag loop handles.

2. Description of Related Art

Grocery bag handles are members of a very crowded art. Many varieties are to be found in the US patent collection going back to 1948, long before the introduction of the modern thin plastic bag. Those closest to the present invention in that they may hold a bag crossways, or hold two or more bags on each end, have a pair of hooks flanking a central gripping portion, but the present invention does not use hooks. U.S. Pat. Nos. 6,651,941 and 6,499,781 by David Kinsel and Norman Flynn, respectively, are representative of this type of bag holder.

U.S. Pat. No. 5,368,393, FIG. 1 by J. B. Norman appears to have superficial resemblance to the present invention, but upon inspection it, it is found that it too, is merely a hooks-on-the-end type, only that the hooks are fabricated integrally with the handle bar instead of being separate and attached to the tip ends of the bar.

Many other types of handles having a groove or similar along the length of the handle were found. The bag handles are laid in a longitudinal groove and the handle gripping portion passes under the bag handles. The grip orientation is similar to gripping the bag without an aid. Unless this type is carefully designed to have the handle load close to the hand contacting surface, the handle will have a tendency to rotate axially and drop the bag off the handle. The present invention cannot drop the bag handle even if the handle is rolled axially. This type of handle cannot hold a bag crossways, that is, one bag loop handle on each end of the handle bar.

Many other patents are of the wrap around type in which a sheet of material is wrapped around the handles to provide a larger surface to support the weight of a filled bag against the hand. These are mechanically similar to the longitudinally grooved handle just described, and have most of the same limitations.

Both of these embodiments hold the handle loops in the plane of the loops.

The present invention is a dumb bell configuration with an annular slot on each end adapted to receive a bag handle. The slot having a bulge at the interior end to allow the bunched bag handle to expand and be gripped by the handle so the handle does not come loose from the bag when set down. The present invention is designed for use transversely across the bag. None of this type were found in the U.S. patent files.

U.S. Pat. No. 5,516,175 by Arthur Christiansen is the only prior art found that has an annular ring to hold the bag handles. This embodiment has a single annular ring in the center of the handle. The fingers of the gripping hand straddle the mounted bag handles. Both bag handles must be fitted into the single ring. To avoid or minimize non-symmetrical loading of the hand, the bag handle must be placed between two fingers, which leaves the load divided between two stronger fingers and two weaker fingers. Furthermore the full load is always born near the middle joint of the fingers. Such an arrangement could fatigue the hand and wrist.

In the present invention, the grip may be placed at the proximal end of the fingers or even in the anterior portion of the palm, next the fingers. Both of these positions should be far less fatiguing than Christiansen's version.

U.S. Pat. No. 466,276, Dec. 29, 1891 by E. Le Garde. Titled “Dumb Bell” shows an exercise dumbbell with ting-aling bells on the ends of a handle. This reference is from non-analogous art. An inventor of ordinary skill in bag handling tools would not expect to find relevant prior art in either athletic equipment or musical instruments. The dumbbell shown in Le Garde FIG. 2 has many of the structural characteristics of the present invention, but probably would not successfully carry a modern plastic shopping bag be cause the axial shaft separating the inner and outer shells of the bell has too small of diameter and would put considerable stress on the bag handle.

Any proposal for enlarging the shaft would destroy the resounding qualities of the bell halves. Bells of this design ring most loudly and clearly when the central support is minimal, so as to not dampen the vibrations of the gong.

Furthermore, the outer edges are sharp and would likely cut the thin plastic handles of a modern plastic bag.

OBJECTS OF THE INVENTION

It is an object of the invention to provide a rigid gripping device as an intermediary between a carrier person's hand and the very flexible (hand binding) loop handles of a common thin disposable plastic grocery bag or the loops of a durable reusable fabric bag.

It is another object of the invention that the handle not tend to rotate axially.

It is another object of the invention that if the handle is rotated axially, it will not disengage from the loop handles of a grocery bag.

It is another object of the invention that if the grocery bag is set down, and the tension of the bag's loop handles on the auxiliary handle is released, the bag will not disengage from the auxiliary handle.

It is another object of the invention that the auxiliary handle be capable of carrying either a single grocery bag or at least two grocery bags,

It is another object of the invention, that during use, the bottom of a loaded grocery bag not be lowered significantly from the “normal” position to where it could drag on the ground when carried by a woman of average stature.

BRIEF SUMMARY OF THE INVENTION

The preferred embodiment of the presently disclosed shopping bag carrying handle is basically a rigid, round, gripping bar with annular slots at each end adapted to receive the loops of a common plastic grocery bag or the loops of a cloth carrying bag. In one embodiment, a bar of wood, plastic, metal, etc is turned to have a central portion adapted to be gripped by the hand of a person and support the load of one or more filled grocery bags. On each end, just outboard of the handle gripping portion are two knobs, each of which have an annular slot for receiving the loop handles of a shopping bag. The slot has a widened interior end, ie, a bulge, which allows the bunched up handle to expand and be retained within the slot with increased friction. When used to support a single bag, the handle is placed transversely across the bag, with one bag loop handle in each of the annular slots. When used to support two or more bags, both loop handles of each bag are placed in one of the annular slots.

Alternatively to turning, the invention may be cast in plastic or metal either in the turned shape or modified to have different handling characteristics.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, the handle 1 has a rigid central gripping portion 3 adapted to be held in a human hand. The preferred length of the gripping portion (grip bar) is approximately 4½ inches long and 1¼ inched in diameter at the center, which is adequate for most adult hands. A longer gripping portion permits the hand to be moved longitudinally along the gripping portion to balance unsymmetrical weight of two or more bags suspended from the ends of the handle. The gripping portion may or may not have surface patterning to improve grippability. FIG. 1 shows a grip enhancing pattern 9 as a series of rounded annular rings which are like the outer portions of torus arranged progressively larger from the ends to the middle forming a surface of undulating, rounded, hummocks. The preferred number of rings is 9, but fewer or more are acceptable and work well for the purpose.

The key feature of the present invention is the large knob on each end of the gripping bar 3. Each knob having an annular slot 6 dividing the knob into separated portions 4 and 5 and connected together by rod 7 at the bottom of the slot. Each slot is defined by two parallel or nearly parallel faces 11 extending from near the outer rims of the knob halves 4&5 inwardly at least ½ the slot depth. The interior end of the slots has an annular bulge 12 at the bottom. The external end of the slot is flared 10 either with a rounded or beveled transition from the slot sides to the knob periphery. In addition to providing a smooth transition (fairing) between the slot and the knob perimeter, flaring creates a funnel like shape to guide the bag handles into the slot and to break what otherwise would be a sharp edge which may cut the thin plastic of a common bag handle.

The bulge 12 at the bottom of the slot allows the bunched-up bag handle to expand thereby locking the handle into the slot which prevents the handle from falling off the bag when the bag is set down in the car for transport or while the user unlocks a car or house door or the like. Yet, the locking is not so secure that the handle is difficult to remove from the bag. One alternative way to produce the bulge is to have the slot walls taper away from each other, forming a wider bottom as illustrated in FIG. 3. Another alternative way to produce the bulge is to have the bulge extend from the interior of the flares to the bottom of the slot. Usually the slot/bulge side walls will open forming a pear shaped bulge. The bag handle will work equally well for carrying bags with the bulge omitted, but may not reliably retain the handles under relaxed conditions.

It has been found that the preferred width of the slot is ⅛ to 3/16 inch, and the bulge has a preferred width of approximately ⅜ inch or less, and a height of at least ⅜ inch.

At these dimensions, the loops fit easily within the slot and because of bunching in the bulge, are locked into the slot, and are retained when the tension is released. This retention is accomplished by friction alone, without mousing, clips, compression closures, or any other devices to prevent disengagement of the bag loop handles from the carrying handle.

Another feature of the present invention not found in the prior art, especially hook variants, is that when the load is lifted, the round handle may roll slightly which balances the tension on the bag handle bands depending from each side of the slot and rod 7. This reduces the likelihood of one band being over stressed and breaking.

The central bag hanging rods 7 are generally cylindrical having a minimum diameter of approximately ½ inch. This is sufficient to provide adequate strength to join the two knob segments, to resist the various forces encountered from heavy suspended loads, and to spread the load on the bag handles so they do not break.

The overall length of the preferred embodiment is approximately 7¼ inches. The knobs are 1½ inches in diameter, and each half has an axial length of approximately ⅜ inch. The outer perimeter of the knobs is gently rounded so as to not have any corners or edges. This prevents the handle from scuffing a car seat while in use, or the insides of a purse or pocket while being transported to the grocery store. At the knob ends, while shown in the figures as being rounded, the rounding is modest, having a radius not of at least 1¼ inches to leave an adequately flat surface to be embossed or printed with a logo, advertising, or other indicia. The axial thickness of the knobs provides strength against cantilever forces applied to the outer half of the knobs when the loaded handle is tipped, causing the bag to hang at an acute angle to the handle axis and bear against the outer knob portion.

Many people like the feel, warmth, appearance, and uniqueness of wood grain. The cylindrical embodiment may be manually turned on a lathe, which, when hand turned, may have the added appeal that each article is shaped slightly uniquely differently. The shape, large radiuses, and cross sectional thickness of the bar, rods, and knobs is ideal for turning in wood.

However, the preferred embodiment may be mass produced by molding in plastic. An optional central bore may be included to reduce the amount of material used.

HOW TO USE THE INVENTION

FIGS. 5, 6, and 7 illustrate the handle holding a grocery bag.

FIGS. 5 and 6 show the bag hanging from the rod 7 within the slots 6, and the handle oriented across the bag.

FIG. 7 illustrates the handle supporting two bags, one from each end.

The loop handles of a loaded grocery bag are passed into the annular slot as previously described, and the assembly of bag and handle grasped in the hand and lifted, to be carried away. However, to improve the ability to prevent disengagement and also to provide slightly more bearing circumference, the loop handles may be twisted 180 degrees before being inserted into the slots. To release the handle, the loops are simply lifted out of the annular slots.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to as falling within the scope of the invention as defined by the claims which follow.
