Abstract:
1. A storage device for transporting equipment, the device comprising: a housing having opposite upper and lower ends and opposite first and second surfaces extending therebetween, and defining at least one compartment for storing the equipment and defining a separate pair of wheel wells, said housing having an opening into said at least one compartment, a door for selectively closing said opening, and a handle mounted to said upper end of said housing; a first and a second retractable wheel mounted on a shaft, said first retractable wheel mounted on a first side of said housing and said second retractable wheel mounted on an opposite second side of said housing, said shaft extending through said housing from said first side to said second side; and an actuator for displacing said first and said second retractable wheels between a refracted position within said wheel wells and an extended position at least partially cantilevered from said second surface, from said lower end of said housing, said actuator only coupled with said lower end of said housing; a latch for releasably locking said actuator when said wheels are in said extended position so as to maintain said wheels in said extended position, wherein said actuator includes a foot pedal disposed in said second surface, in said lower end of said housing and cooperating with said shaft for rotation of said shaft upon movement of said foot pedal relative to said housing, and wherein said wheels are mounted on at least one arm mounted on said shaft for simultaneous rotation of said at least one arm upon said rotation of said shaft, wherein said actuator is exclusively a foot pedal actuated mechanism only actuated by actuation of said foot pedal, said mechanism in operable communication via a mechanical linkage with said wheels such that said wheels are disposed within said wheel wells when said linkage is in a first position and such that said wheels extend outwards from said wheel wells when said linkage is in a second position, wherein said latch includes a manually operable lever cooperating with a receiver, said lever mounted in said second surface for selectively releasable registration of an end of said lever with said receiver, said receiver mounted to said linkage wherein, with said end of said lever engaged in said receiver said linkage is locked statically relative to said housing and wherein when said lever is dis-engaged from said receiver said linkage is free to move relative to said housing, wherein said receiver is mounted on, for rotation with, said shaft, wherein said receiver includes a notched cam member, wherein said second surface is a rear surface and said first surface is a front surface, wherein said foot pedal is rotatably mounted in said rear surface and is coupled to a rigid drive member so that rotation of said pedal translates said drive member causing said drive member to rotate a bell-crank mounted on said shaft, said rotation of said bell-crank causing said retractable wheels to extend into said extended position against the return biasing force of said spring.
