Abstract
Abstract A piece of luggage has a case with a substantially flat bottom wall formed with a pair of generally parallel grooves, with a pair of longitudinally spaced relatively wide outwardly open recesses in each groove, and with a wheel cutout adjacent a lower end of each groove. Respective solid support blocks are force-fitted in the recesses and are each formed with a throughgoing passage aligned with the respective groove. Respective tubes extend longitudinally along the grooves through the respective passages in the blocks and are rotatable in these blocks. Pivot mounts for wheels are carried on the lower tube ends and a handle is connected to the upper tube ends and are displaceable longitudinally relative thereto. Structure in the tube between the handle and the pivot mounts pivots these mounts through about 90° between positions with the wheels in the cutouts and the wheels standing up from the bottom wall on displacement of the handle longitudinally away from the upper tube ends.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
A piece of luggage comprising: a case having a substantially flat bottom wall formed with a pair of generally parallel, relatively narrow, and outwardly open elongated grooves having upper and lower groove ends, a pair of longitudinally spaced, relatively wide, and outwardly open recesses at each groove between the ends thereof, and a wheel cutout adjacent each lower groove end; respective solid support blocks force-fitted in said recesses and each formed with a throughgoing passage aligned with the respective groove; respective tubes extending longitudinally along said grooves through the respective passages and rotatable therein and having upper tube ends at said upper groove ends and lower tube ends at said lower groove ends; respective pivot mounts carried on said lower tube ends; respective wheels journaled on said pivot mounts; a handle connected to said upper tube ends and displaceable longitudinally relative thereto; and means in said tubes between said handle and said pivot mounts for pivoting said mounts through about 90° between positions with said wheels in said cutouts and with said wheels standing up from said bottom wall on displacement of said handle longitudinally away from said upper tube ends.
Claim 2
Dependent Claim
