Abstract

Pneumatic tools are staple elements of constructions sites. Pneumatic tools are often hand-carried to specific locations and balanced on an available surface or between the knees of a worker while the worker uses two hands for related activities. A universal quick-change hook according to an embodiment of the invention can be coupled between fittings of a pneumatic tool and pneumatic hose without obstructing airflow though the fittings and provides a hook stop to protect fittings attached to the universal quick-change hook, preventing accidental activation of a connection release. The universal quick-change hook is configured to support the weight of an attached tool from a wide variety of different support means, such as a ladder, lumber stock, nail, or utility belt. The universal quick-change hook provides a worker with a convenient way to secure a hook to pneumatic tools in rapid fashion to be more efficient and competitive on a jobsite.

Dependent claims

A universal quick-change hook for hand-held pneumatic tools, comprising:

a main body having a first end and a second end;
a fitting interface region at the first end of said main body, wherein the fitting interface region extends in a horizontal direction;
a fitting extension region between the first the second ends of said main body and adjacent to the fitting interface region, wherein the fitting extension region extends downwardly at an angle below the fitting interface region;
a fitting bend located at an intersection of said fitting interface region and said fitting extension region, said fitting bend defining an inside surface of said main body and an outside surface of said main body;
a pneumatic fitting coupled to the main body in the fitting interface region in an orientation enabling a direction of airflow though the pneumatic fitting perpendicular to the main body at the fitting interface region, said pneumatic fitting having an inlet and an outlet with a flow path therebetween;
a hook region at the second end of said main body and adjacent to the fitting extension region, wherein the hook region extends downwardly from the fitting extension region at an angle below the horizontal direction;
a hook stop projecting from said inside surface of said main body at an intersection of the fitting extension region and the hook region.
