Abstract

The present invention discloses a portable work station that provides a strong work surface combined with a significant volume of secure tool storage. The disclosed invention allows a single user to collapse, load, transport, unload, assemble and move the apparatus to a specific work area without assistance. Once at the designated work site, the apparatus of the present invention can be locked in place, preventing unwanted motion during use. Further, the disclosed invention provides an adjustable height work surface that includes the ability to transport large construction materials safely.

Claims

a rear surface, said rear surface having a handle bar and a pair of latch buttons, one of said pair of latch buttons disposed on each end of said rear surface wherein said handle bar is used both to control a rear latch mechanism and to urge said rectangular volume into and out of a transport condition and said pair of latch buttons control a front latch mechanism;

a first side surface;

a second side surface;

a bottom surface;

a top surface, said top surface having one or more sections hingably attached to said first side surface, said one or more sections being capable of being locked;

a first set of roller wheels fixably mounted in close proximity to the front surface of said rectangular volume;

a second set of roller wheels fixably mounted two thirds of the way from said front surface of said rectangular volume;

one or more storage compartments formed by said front surface, said rear surface, said first side surface, said second side surface, said bottom surface and said top surface, said one or more storage compartments being accessible by the one or more of said hingably attached sections of said top surface;

a front pair of collapsible telescoping legs hinged at said front of said rectangular volume, said front pair of collapsible telescoping legs further comprised of;

a front outer fixed leg portion and a front inner telescoping leg portion, said front outer fixed leg portion and said front inner telescoping leg portion having a plurality of front mating height adjustment holes;

a set of fixed wheels, one of said set of fixed wheels disposed at the end of each of said front inner telescoping leg portions;

said front latch mechanism capable of locking said front pair of collapsible telescoping legs in a locked position, and;

a secondary loading wheel disposed in the center of said front set of collapsible telescoping legs approximately one third of the way from the bottom surface of said rectangular volume;

a rear pair of collapsible telescoping legs hinged at said rear of said rectangular volume, said rear pair of collapsible telescoping legs further comprised of;

a rear outer fixed leg portion and a rear inner telescoping leg portion, said rear outer fixed leg portion and said rear inner telescoping leg portion having a plurality of rear mating height adjustment holes;

a set of rotatable wheels, one of said set of rotatable wheels disposed at the end of each of said rear inner telescoping leg portions, and;
