Abstract
Abstract An infant carrier (2) for secure attachment of a shopping cart (4). The infant carrier includes a seating section (5) for supporting the infant. The seating section includes a bottom portion (6) and a back portion (8) disposed at an angle to the bottom portion. Side portions (10) are located adjacent to and substantially perpendicular to the back and bottom portions. Rear side extensions (12) are coplanar with the side portions, extending rearwardly therefrom, and include a lock (14) for securely attaching the carrier to a horizontal wire (20) of the shopping cart. The lock is disposed on a rear surface (13) of the rear side extensions in an elongated opening (26) formed in the rear surface. The lock includes a resilient cantilever member (28) connected by a connection end (32) at a lower end (30) of the opening. A latch (34) is disposed remote from the lower end for retaining the horizontal wire within a recess (22) formed in the rear side extension. To lock the horizontal wire in the recess, the infant carrier is positioned such that the latch contacts the horizontal wire. The infant carrier is pushed downwardly such that the horizontal wire exerts a force (arrow A) on the latch, pushing the resilient member into the opening. The horizontal wire is thus received in the recess. The resilient member is biased to its normal position such that an upper support surface (42) of the latch retains the horizontal wire within the recess.
