Patent Abstract:
A handle grip and handle grip assembly for shopping baskets. A pair of identical handle grips are fabricated of molded plastic, each comprising a unitary body component and cover component connected by a hinge component. A handle element is seated in each body component and the corresponding cover component closes over the handle element and is locked to the body component. The cover components of the grips engage each other when the basket is carried and the weight of the basket increases the engagement force.

Full Description:
FIELD OF THE INVENTION 
     This invention relates generally to a handle grip for wire handle containers and the like. It relates particularly to a handle grip for shopping basket handles. 
     BACKGROUND OF THE INVENTION 
     Hand carried shopping baskets are popular with customers in grocery stores, for example, where smaller quantities of goods are involved, i.e., where wheeled shopping carts are unnecessary. Conventional baskets have two wire handles, each in an inverted U-shaped configuration, pivotally connected to a basket rim in spaced relationship. The basket might be fabricated of wire, itself, although molded plastic baskets are now widely used. 
     To carry the basket, the two basket handles are brought together and gripped by the shopper in a well-known manner. The basket can be carried easily and little, if any, discomfort is caused by the wire in the shopper&#39;s hand when the basket is empty or only lightly loaded. When the basket is loaded, however, its weight causes the wire handles to painfully press into the shopper&#39;s hands because forces are concentrated. 
     Of course, there have been numerous force dispersion handle grips designed for wire handles in the same or similar environments. An example is illustrated in the Sweeny U.S. Pat. No. 4,932,702. None affords a high degree of shopper comfort while still being simple, inexpensive and highly reliable, however. The present invention is directed toward overcoming the shortcomings of the prior art. 
     SUMMARY OF THE INVENTION 
     A primary object of the present invention is to provide a new and improved handle grip for shopping basket handles or the like. 
     Another object is to provide a one-piece, molded plastic handle grip which closes and locks securely on each wire handle of a shopping basket. 
     Yet another object is to provide a handle grip which is mounted so that the force exerted on the grip during use serves to further prevent opening of the handle. 
     Still another object is to provide a handle grip which is simple and inexpensive in construction. 
     A further object is to provide an improved handle grip assembly for two handles on a shopping basket. 
     The foregoing and other objects are realized in accord with the present invention by providing a clam-shaped, one-piece, molded plastic handle grip which closes and locks securely on each wire handle or bail of a shopping basket. The grips associated with the two handles abut each other when they are grasped in the shopper&#39;s hand to carry the basket. This force exerted on the grips causes each grip to remain securely closed and, in fact, as the load in the basket increases the force holding the grip closed increases. The size and shape of each grip, and the assembly of grips, obviates shopper discomfort normally associated with carrying a loaded basket.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, and particularly to FIGS. 1 and 2, a conventional shopping basket is seen generally at 10. The basket 10 is fabricated of molded plastic, and is adapted to be carried by a shopper through the medium of two U-shaped (inverted) wire handles 11 and 12. As will be seen, each handle 11 and 12 includes a pair of legs 20 pivotally connected to the basket 10, and a base 21 connecting the legs. 
     Each handle 11 and 12 is fabricated in a conventional manner from either 8 or 9 gauge steel wire. The wire base 21 of each handle 11 and 12 has an offset section 24 at its mid-point, and a handle grip 30 embodying features of the invention is mounted on it. The handle grips 30 for both handles come together in flush, mating relationship when they are gripped by a shopper, as seen in FIG. 2. 
     Referring now to FIGS. 4-7, a handle grip 30 is shown in its open configuration, i.e., as it appears after fabrication and before mounting on a basket handle 11 or 12. The grip 30 is molded in one piece of plastic using conventional techniques. In the preferred embodiment, the plastic used is a polypropylene. 
     The handle grip 30 comprises an elongated body component 31 and a correspondingly elongated cover component 32 joined by a somewhat shorter, but still elongated, hinge component 33. The body component 31 is 4 inches long, 0.750 inches deep and 0.598 inches wide in the embodiment illustrated. The cover component 32 is slightly shorter and slightly narrower, for reasons which will hereinafter become apparent. 
     The body component 31 comprises a combined outer side wall and bottom wall 41 which is scalloped along its length to create four indentations 42 for receipt of the four fingers of a shopper&#39;s hand. The wall 41 is arcuate in cross-section along its length. The radius of the arc varies, however, depending upon the position on the wall 41 in relation to the four indentations 42. 
     The body component 31 also comprises a top wall 44 which joins the combined outer and bottom wall 41. The top wall 44 includes an elongated central wall section 46 and bracketing outer wall sections 47. The central wall section 46 and bracketing outer wall sections are each flat. However, the outer wall sections are inclined downwardly relative to the central wall section 46, as best seen in FIG. 4. 
     The body component 31 also comprises two end walls 51, and three internal compartment walls 52 which lie parallel to the end walls. The compartment walls 52 provide structural rigidity to the body component 31. 
     The end walls 51 and the compartment walls 52 each have a roughly semi-circular depression 55 formed therein, as best seen in FIG. 7. These depressions 55 collectively define a receptacle for the offset section 24 of each wire handle, the insertion of which will hereinafter be discussed in detail. 
     Piercing the arcuate outside and bottom wall 41, in a horizontal path at each of the four scalloped indentations 42, are four locking ports 61. Each of the four locking ports 61 includes a vertically oriented locking lip 62 (see FIG. 9). The operation of the ports 61 and corresponding locking lips 62 will hereinafter be discussed in the context of the assembly of the handle grip 30. 
     Turning now to the cover component 32 of the grip 30, it will be seen to have a configuration corresponding to that of the inner, exposed side of the body component 31. As such, it comprises a flat wall 71 which has scalloped outer indentations 72. Extending perpendicular to the wall 71, at the base of each indentation 72, is a locking tab 73. Each locking tab 73 has a locking shoulder 74 formed on its lower surface, the purpose of which (as hereinafter discussed) is to mate with a corresponding locking lip 62 in the arcuate outside and bottom wall 41. 
     The components 31 and 32 are formed unitarily with, and joined by, the hinge component 33, as has been pointed out. The hinge component 33 is approximately one-half the thickness of the walls 41 and 44 making up the components 31 and 32, as will be seen. In this regard, the walls 41 and 44 are approximately 1/8 inch thick and the hinge component 33 is approximately 1/16 inch thick in the handle grip 30 illustrated. The cover component 32 pivots on the hinge component 33 to mate with the body component 31 and form a flat inner side wall for the handle grip 30. 
     Referring now to FIGS. 3, 8 and 9, in addition to FIGS. 1-7, a grip 30 is shown as it is being closed and locked onto a wire handle section 24 (FIG. 9) and as it appears when locked on (FIGS. 3 and 8). The wire section 24 is first seated in the depressions 55 formed in end walls 51 and compartment walls 52 of the body component 31. The cover component 32 is then closed over the body component 31. 
     As the cover component 32 closes, the hinge component 33 bends, acting as a hinge. The locking tabs 73 enter corresponding locking ports 61. The locking shoulders 74 pass by, and snap behind, corresponding locking lips 62. As best seen in FIG. 8, the cover component 32 is then permanently locked closed over the body component 31. The tabs 73, in entering the locking ports 61, bend outwardly in elastic deformation until their shoulders 74 pass the lips 62, when they return to their undeformed shape, creating the locking effect described. 
     The external dimensions of the cover component 32 are such that it nests inside the body component 31, as best seen in FIGS. 4 and 8. As such the cover component 32 nests between portions of the two end walls 51 of the body component 31. 
     The handle grips 30 for each handle 11 and 12 are identical. However, as will best be seen in FIG. 2, they are oriented 180° from each other when mounted on corresponding handle sections 24. As such, the cover components 32 of two grips 30 engage each other when the basket 10 is lifted. As the basket 10 is loaded, the grips 30 are pressed tightly together. The effect is that the only forces acting on the grips 30 serve to maintain their closed relationship with the handles 11 and 12, rather than disturb it. 
     While preferred embodiments of the invention have been described, it should be understood that the invention is not so limited and modifications may be made without departing from the invention. The scope of the invention is defined by the appended claims, and all devices that come within the meaning of the claims, either literally or by equivalence, are intended to be embraced therein.
