Claim 1
Independent Claim
343 words
A luggage carrier comprising: (a) an upright frame member; (b) a handle assembly affixable to said frame member and projecting therefrom; (c) a base support member pivotably carried by said frame member; (d) a pair of wheel assemblies for transporting said luggage carrier, each of said wheel assemblies having means for pivotly connection to said frame member whereby said assemblies are moveable from an operative position to an inoperative position; and (e) further means for moving said wheel assemblies from said operative to said inoperative position responsive to upward pivotal movement of said base support member, further comprising: (f) said upright frame member being an inverted generally U-shaped tubular rod having a pair of parallel side arms and a connecting horizontal extending portion; (g) said handle assembly having adjusting means for extending collapsing and pivotly locking said handle assembly to said connecting horizontal extending portion of said frame member; (h) said base support member being a generally U-shaped tubular rod having a pair of parallel side sections each having a free end at one end and at their opposite ends an offset connecting end section, an axle rod extending through said side sections and pivotably mounted on said side arms of said frame member; (i) each of said wheel assemblies including a bracket having a hooked portion and a wheel rotatable on said bracket, said bracket pivotable on one of said side arms on said frame member in which said free end of each of said side sections of said base support member can engage with said hooked portion on said bracket when said base support member is down to keep said wheel assembly in said operative position; and (j) said moving means being an elongated spring extending between said brackets of said wheel assemblies whereby when said base support member is placed in an upward position, said free ends of said side sections will disengage from said hooked portions allowing said spring to pull said wheel assemblies inwardly towards each other to be flush with said side arms of said frame member.
