Abstract
A transport apparatus is arranged to include a platform pivotally mounted relative to and within the legs of a table structure, whereupon the platform includes lever apparatus to cantilever the platform and project wheel members of the platform to engagement to an underlying support surface to permit rolling support of the table structure.
Claims3
A transport apparatus, comprising,
- a table member, the table member including a plurality of forward legs spaced from a plurality of rear legs, and the table member including a table support top plate, with the top plate having a side wall flange extending at least between the rear table legs, and
- a carriage plate, the carriage plate positioned below the table support top plate and including a carriage plate forward end wall spaced from a carriage plate rear end wall, a carriage plate top wall spaced from a carriage plate bottom wall, and carriage plate side walls, with a plurality of caster wheels mounted to the carriage plate bottom wall in adjacency to the carriage plate rear end wall, with each carriage plate side wall including an axle, each said axle linearly aligned relative to one another, and each said axle pivotally mounted within one of said forward table legs, and
- a mounting flange orthogonally and fixedly mounted to the carriage plate top wall in adjacency to the carriage plate rear end wall, with linkage means extending between the table side wall flange and the mounting flange to effect displacement of the caster wheels from a first position spaced from an underlying support to a second position in engagement with an underlying support, and
- the linkage means includes a table side wall clamp, the table side wall clamp includes a side wall clamp receiving slot receiving said table side wall flange therewithin, and a table side wall clamp fastener directed through said table side wall clamp into said table side wall clamp receiving slot, and the table side wall clamp having a plurality of spaced clamp boss plates and a clamp front wall, with the clamp boss plates mounted to said clamp front wall, and a lever plate, the lever plate including a lever plate first end spaced from a lever plate second end, the lever plate first end including a lever axle directed through said lever plate adjacent said lever plate first end and orthogonally through said clamp boss plates, said lever plate second end including a pedal flange to permit ease of projection and pivoting of the lever plate about said lever axle, and an actuator link extending from said lever plate intermediate said lever plate first end and said lever plate second end, with the actuator link extending pivotally to said mounting flange from said lever plate, whereupon pivoting of said lever plate effects projection of said carriage plate to said underlying support surface.
