Total Claims: 14
Claim 1
Independent Claim 213 words
A shopping cart for counter-level discharge from the basket thereof and for telescoping storage of the carts and baskets when not in use, comprising, in combination: a cart with an elevated basket support, an elongated basket on the basket support having rear and front ends and provided with a movable upright rear wall that permits telescoping of baskets, handle means operatively associated with the basket carrying cart for applying push and pull forces to the cart for controlling movement of the cart, the handle means including a handgrip that is normally positioned at a level between the upper and lower boundaries of the upright rear wall of the basket so as to be located at a convenient level for the user of the basket, but which is at a position to normally obstruct telescoping of the baskets, releasable means operatively connecting the handgrip to the basket upon a downward force being applied to the handgrip, and means on the basket adapted to be engaged by another basket for effecting release of the releasable means and for effecting movement of the handgrip upwardly away from its operative position to a position that permits telescoping of the baskets when the forward end of one basket begins to move toward a telescoping relationship with another basket.
