Welding Table Elevating and Rolling

A welding table with elevation system, powered with cordless drill, gear reducer, chain, sprockets and, ultimately turning screw posts synchronously, lifting four telescoping legs. Maximum elevated height exceeds most work benches for height matching, and a minimum height goes lower than most low tables. Folding wheel system is independent, lever operated, and works in conjunction with the elevation system. Once table rolls into position, drill is activated, braking is instant, the table lifts itself from the wheels. Wheels are then folded up, a position necessary during minimum height, as the frame gets closer to the ground. This low height enables sitting roll stool usage, and knees and legs enter the rear frame opening. Two drawers above conceal the wheels, have a lever locking system, and necessary when rolling the table. The table top is heavy, one piece removable with normal modular patterned holes throughout, and the addition of large oval holes, and top side overhang, both establishing C-Clamp usage.

Hole-Less Editable Binding System

A system for externally binding a stack of loose-leaf paper, fabric or other flat media by hand for presentation purposes without a need for creating a spine, hole-punching paper, permanent covers or insertion into pre-constructed sleeves. It employs a slim, external bar made of a dense material, placed in the margin area on the front side of a paper or fabric stack and a rigid backing board on the rear side. The entire assembly is held together firmly by threaded bolts and adjoining screw posts that are adjusted depending upon the quantity of sheets included and their thicknesses. The stack is compressed and decompressed by tightening or loosening the threaded bolts whenever sheets are added or removed. The low-profile system firmly grips paper or fabric with unlikely slippage, requires no heat or adhesives, and provides the ease of turning the pages or sheets as typical in a perfect-bound book. It accommodates common lengths of paper stock and fabric swatches, and multiple thicknesses within the same stack.
