Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 237 words
A child carrier comprising seat means having a seat base including a foot end, head end, a back, and side walls; a spring-biased latch extending through said back of said seat means; a base geometrically configured so as to mate with the bottom of said seat means, said base having a bottom surface, a head end, foot end, and side walls; a frame movably mounted within said base and being configured at one end so as to mate with and move with said spring-biased latch; a pair of steel hooks pivotally mounted within said base, said hooks being of a substantially wear-resistant material; means for securing the other end of said frame to said hooks; a second spring for biasing said frame in a direction so as to maintain said hooks in a substantially upwardly extending position; a pair of orifices in the bottom of said seat means configured so as to mate with said hooks when said seat means is placed on said base; an L-shaped steel plate secured adjacent each of said orifices for mating with said hooks, said L-shaped plates being of a substantially wear-resistant material; whereby movement of said spring biased latch in one direction moves said frame so as to overcome the bias of said second spring and rotate said hooks to a position of non-engagement with said L-shaped plates so as to permit removal of said seat means from said base.
