  • Patent number: 4609183
    Abstract: A shopping cart corral kit having modular components for assembling and disassembling the modular components in the parking area of a business establishment providing shopping carts for its customers. The corral kit modular components can be assembled with conventional fasteners without welding and without exposing sharp edges. The modular components are small enough in size to be shipped in a carton unassembled to permit the business establishment's personnel to assemble the component parts. The major modular components are constructed of galvanized tubing or pipe that may be provided with a colored plastic coating to prevent rust.

  • Patent number: 4589513
    Abstract: The device includes an open topped housing, the bottom of which is interconnectable to a vehicle steering column through an adapter plate. A biasing plate is slideably supported in a horizontal position in the housing on a number of spaced vertical posts secured to a base plate in the housing. The biasing plate bears a number of spaced ridges extending up from the periphery thereof and defining peripheral recesses therebetween. A horizontal ring locking plate is fixed to the top of the posts above the biasing plate and bears spaced teeth defining a number of notches therebetween with the teeth partially overlying the biasing plate ridges. Coiled springs on the posts push up the locking plate. A lever secured to the biasing plate is needed to selectively move that plate down from the locking plate. A keylock in the housing extends out therefrom and releasably locks the biasing plate up against the locking plate.

  • Patent number: 4560180
    Abstract: A shopping cart of the over-the-counter type that includes front gates that slide under the basket of the shopping cart for storage purposes. The gate bumpers that are constructed and defined to permit the slide under action are interlocked with the front gate to prevent the ready theft of the front gate from the shopping cart. The front gate is provided with a positive latch to the basket to further prevent the unintentional opening of the gate. The baby seat compartment has a gate that may be pivoted forwardly and rearwardly as well as an upright back supporting position. The shopping cart is constructed of a single frame element for supporting the basket and baby compartment and functioning as a cart handle. The basket is pivotally supported on the frame element to permit it to be swung rearwardly to a storage position over the baby seat compartment. The forces transmitted to the baby seat compartment for elevating the basket are transmitted to the handle rather than the baby seat compartment.
