Patent ID: 7694832

Claim:
A suspension display rack for tools comprising: a rail having a back-strip being longitudinal and flat and having an inner surface, a top edge, a bottom edge and two opposite ends; two hooks being longitudinal, being formed on and perpendicularly protruding from the inner surface respectively at the top and bottom edges of the back strip and each hook having a longitudinal groove defined in the hook and having a curved inner surface, and the curved inner surface having an arcuate outline; and two securing members defined respectively at opposite ends of the back-strip; multiple sliding blocks mounted slidably in the rail and each sliding block having a base being substantially V-shaped and having a thickness; and two supporting plates separated from the inner surface of the back strip at an interval, connected to each other with an included angle being obtuse and each supporting plate having a distal end; two cylindrical slides formed respectively on the distal ends of the supporting plates of the base, slidably mounted respectively in the longitudinal grooves of the hooks and each cylindrical slide having a diameter being larger than the thickness of each supporting plate; and a circular cross section corresponding to the arcuate outline of the curved inner surface of the longitudinal groove of one hook; and a seat being substantially U-shaped body, formed on the distal ends of the supporting plates of the base and having two lateral plates formed on and perpendicularly protruding respectively from the distal ends of the supporting plates of the base and each lateral plate having a thickness and a distal end; an upright plate formed perpendicularly between the distal ends of the lateral plates and having a thickness; and a central space surrounded and defined by the supporting plates, the lateral plates and the upright plate and having a height, a width and a depth and each of the height, width and depth of the central space being larger than the thicknesses of supporting plates, lateral plates and upright plate, wherein the seat of each sliding block is a semi seat and each of two adjacent sliding blocks cooperates with each other to form a clamp; the semi seat of each sliding block has two arcuate cutouts defined respectively in the lateral plates of the semi seat and being parallel to each other; and the arcuate cutouts on the semi seat of one of the adjacent sliding blocks respectively face the cutouts on the semi seat of the other sliding block.
