Abstract
A tool device is disclosed to include a hollow upright pivot shaft, coupling rings rotatably mounted on the hollow upright pivot shaft at different elevations, and support arms respectively coupled to the coupling rings and turnable with the respective coupling rings about the hollow upright pivot shaft, each support arm having a plurality of open receiving chambers respectively vertically cut through the top and bottom walls thereof for holding hand tools, each open receiving chamber having a front opening, a top opening connected to the top open side of the front opening, and a bottom opening.
Claims10
A tool storage device comprising:
- (a) a hollow upright pivot shaft having two ends, a top end and a bottom end;
- (b) the hollow upright pivot shaft end capped on the top end and the bottom end;
- and
- (c) a plurality of coupling rings respectively mounted on the hollow upright pivot shaft at different elevations, and a plurality of support arms respectively coupled to the coupling rings, each of the support arms having a proximal end, a distal end, a front wall, a top wall, and a bottom wall, and a plurality of open receiving chambers respectively vertically cut through said top and bottom walls for holding hand tools, each said receiving chamber having a top opening in said top wall, and a bottom opening in said bottom wall,
- wherein each said support arm has a male coupling block at the proximal end thereof for coupling one coupling ring;
- each coupling ring has a female coupling block at the periphery thereof for receiving the male coupling block of one said support arm, and
- wherein the male coupling block of each said support arm has a T-shaped coupling portion;
- the female coupling block of each said coupling ring defines an upwardly extended T-groove for receiving the T-shaped coupling portion of the male coupling block of each said support arm.
