Abstract
Abstract A rollable cart that may be readily assembled from a knock-down condition using conventional fasteners and tools and with a minimum of skill is disclosed. The rollable cart includes a chassis having a pair of pivotable, relatively small front wheels and a pair of larger, rear wheels. A three-sided housing defined by a front, a rear and a side panel is mounted on the chassis. The fourth side is open so that articles may be placed into and taken out of the housing. Side edges of the front and rear panels and the side panel are provided with a plurality of vertically spaced apart L-shaped notches. A plurality of shelves each having front and rear pairs of downwardly opened notches is also provided. The shelves may be adjustably positioned in the housing by transverse front and rear bars on which the shelves rest. The ends of the transverse bars are received in the L-shaped notches of the front, rear and side panels, which L-shaped notches are in registry with one another. The combination of the L-shaped notches and the transverse bars also provide for coupling securement of the front and rear panels to the side panel. The housing may also include a tray at the upper end thereof, a handle at the rear end thereof, hanger members at the forward end thereof and platforms at the lower, forward and rear ends thereof.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
270 words
A device comprising: a chassis having front and rear ends; a housing mounted on and extending upwardly from said chassis, said housing including opposed front and rear panels and a side panel extending therebetween, said front, rear and side panels each having a pair of upright, elongated side edges; at least one shelf mounted in said housing, said shelf extending along said side panel and longitudinally between said front and rear panels; securing means for coupling the side edges of said side panels to opposed side edges of said front and rear panels, said securing means also serving to adjustably support said shelf in said housing to permit said shelf to be selectively positioned at different heights above said chassis; said securing means including a plurality of L-shaped notches spaced apart along said side edges of said front, rear and side panels with a first leg of said L-shaped notches terminating and being open at said edge of each of said panels and with the second leg of each said L-shaped notches extending in the same direction as the upright edges of said panels; said L-shaped notches in said side panel being in registry with said L-shaped notches in said front and rear panels; side edges of said shelf having opposed, downwardly open notches proximate forward and rear ends thereof, said shelf notches being in registry with the second legs of said L-shaped notches; and said securing means further including elongated bars each having opposed ends which are removably positioned in said registered L-shaped and shelf notches, whereby said device is readily disposed in a knocked-down condition for shipping thereof.
Claim 2
Independent Claim
270 words
A device comprising: a chassis having front and rear ends; a housing mounted on and extending upwardly from said chassis, said housing including opposed front and rear panels and a side panel extending therebetween, said front, rear and side panels each having a pair of upright, elongated side edges; at least one shelf mounted in said housing, said shelf extending along said side panel and longitudinally between said front and rear panels; securing means for coupling the side edges of said side panels to opposed side edges of said front and rear panels, said securing means also serving to adjustably support said shelf in said housing to permit said shelf to be selectively positioned at different heights above said chassis; said securing means including a plurality of L-shaped notches spaced apart along said side edges of said front, rear and side panels with a first leg of said L-shaped notches terminating and being open at said edge of each of said panels and with the second leg of each said L-shaped notches extending in the same direction as the upright edges of said panels; said L-shaped notches in said side panel being in registry with said L-shaped notches in said front and rear panels; side edges of said shelf having opposed, downwardly open notches proximate forward and rear ends thereof, said shelf notches being in registry with the second legs of said L-shaped notches; and said securing means further including elongated bars each having opposed ends which are removably positioned in said registered L-shaped and shelf notches, whereby said device is readily disposed in a knocked-down condition for shipping thereof.
