2. Description of Related Art
Many consumers have faced the battle of trying to prevent a shopping or grocery cart from rolling away while trying to unload it, this is particularly important if a child is still in the grocery cart seat. Sometimes it is also difficult to keep the shopping cart from banging into the consumer's car or other cars in a parking lot.
Many attempts have been made to fix this problem. However, most conventional devices used to keep a shopping cart from rolling away involve the use of wheel brakes, which are often cumbersome to use. Further, these conventional devices are not installed on all carts and the user often times has no means of using them personally to restrain the cart. Moreover, conventional devices are cost prohibitive for a manufacturer to install. Still further, conventional devices are even more cost prohibitive for a store owner to retrofit the current inventory of shopping carts. Additionally, if the store owner desired to retrofit the current inventory of shopping carts, the retrofit process would take the shopping carts being modified out of service, which is not a desirable action.
Accordingly, it appears there exists a need to keep shopping/grocery carts from rolling away or banging into other objects, such as cars, and to meet this need without presenting manufacturers and store owners with an unreasonable expense or burden.
It is the object of the present invention to overcome the drawbacks and shortcomings of conventional devices in use for keeping shopping carts from rolling away. This present invention allows for a user of shopping carts to attached the present invention to a shopping cart and keep the shopping cart from rolling away or colliding with other objects.
Further, the present invention allows for a conscientious store owner to retrofit a current inventory of shopping carts with the present invention at a reasonable cost and with no loss of service time for the shopping carts.

The first member or suction cup 120 is the same as the suction cup 20 in the device 10. The suction cup has a base portion 122 and a stem portion 124. The second member or handle 140 is different from the second member described in the device 10 in that the second member 140 is one portion having a hollow cylindrical shape. The second member 140 has a first end 144 and a second end 149. The second member 140 includes a bore or hollow core 154, which extends from the first end 144 through to the second end 149. In this embodiment the second end includes a cavity 151 that has a diameter that is large enough to receive the stem 124. The stem 124 is affixed to the interior of the cavity at the second end 149 of the second member. The cavity 151 is also operably configured to receive both ends of the third member 180 as will be discussed further below.
The third member or cord 180, is similar to the cord 80 in the device 10, in that the cord 180 has a length defined by a first end and a second end. Prior to placing the second end 149 over the stem portion 124, both the first end and the second end of the cord 180 are inserted into the first end 144 through to the second end 149. The first and second ends of the cord 180 are tied in a figure-of-eight loop knot (or affixed together through some other conventional means), such that a loop 182 is formed exterior to the first end 144 of the handle 140. The loop 182 is pulled such that the knot is wedged tight inside the cavity 151 of the handle 140.
The fourth member or connector 160 is different from the fourth member 60 of the device 10. In this embodiment, the connector 160 is a conventional carabineer clipped onto the loop 182 of the cord 180.
The device 100 is used in the same way as the device 10 is used. The user 2 presses the suction cup 120 onto a side of the vehicle and then hook the carabiner 160 to a bar 5 of the shopping cart 4.
The fourth member 200 further includes a first orifice 268 and a second orifice 269. The first orifice 268 starts on the second surface at a point that is at the intersection of the midpoint of the length 291 and the width 262. The first orifice 268 has diameter and a depth. The second orifice 269 has a diameter and a height.
In the present embodiment, the length 291 is 2.634 cm and the width 262 is 0.634 cm. The height 263 of the first member 60 is 0.500 cm. The diameter 270 of the first orifice 268 is 0.310 cm and the depth 271 is 0.400 cm. The diameter 272 of the second orifice 269 is about 0.185 cm. It should be appreciated that in other various exemplary embodiments, the dimensional value presented may be changed depending on the size desired for the device 10.
The fourth member 200 is different from the fourth member 60, in that the fourth member 200 includes a first portion 260A and a second portion 260B, and a plurality of fasteners 310. Further, the first portion 260A includes two additional orifices, orifices 276 and cavities 277. The cavity 277 in the present embodiment is six sided to allow the fit of a fastener, such as a six sided nut. It should be appreciated that in other various exemplary embodiments other fasteners common in the art may be used and the cavity operably configured to receive the fastener chosen. The orifices 276 are the same as the orifice 269, however, the orifices 276 allow for the fastener 310 to pass through the first portion 260A.
The first of the orifices 276 and cavities 277 is disposed on one side of the cavity 268 halfway between the cavity 268 and the first end 265. The second of the orifices 276 and cavities 277 is disposed halfway between the cavity 268 and the second end 266.
The second portion 260B has a length and a width 291 and 292, which are equal to the length and width of the first portion 260A. The second portion 260B has a height 263, a first surface 293 and a second surface 294. The second portion 290 further includes a plurality of orifices. The first orifice 299 corresponds to the orifice 269 of the first portion. The orifice 299 allows for the cord 80 to pass through. Two more orifices 296 are disposed on the second portion opposite the two orifices 276 of the first portion 260. The two orifices 296 allow for the plurality of fasteners 310 to pass through the second portion 290.
The second portion 260B further includes two cavities 297, similar to the cavities 277 on the first portion 260A. The cavities 297 in the present embodiment are circular and operably configured to receive a head of the fastener 310. Further, the fastener 310 used in the present embodiment is a bolt and nut fastener common in the art. It should be appreciated that in other various exemplary embodiments, other fasteners common in the art may be used.
The first portion 260A and second portion 260B in the present embodiment is molded out of acrylonitrile butadiene styrene (ABS) hardened plastic similar to the handle 40. The first portion 260A and second portion 260B are not solid, and the portions include a plurality of vanes 275 to reduce weight and material required in manufacturing, as is common in the art of molded plastics. It should be appreciated that the first and second portions could be constructed out of other materials such as wood or metal, for example.
When the fourth member or connecter 200 is in use, the first and second portions 260A and 260B are affixed to the shopping cart with the plurality of fasteners 310. The device 10 is not removable by the consumer. The device 10 with the fourth member 200 provides a way for the store owner to modify an existing inventory of shopping carts without great expense and without taking the shopping carts out of service.
