Abstract
A coupling for the handle shaft of a power driven implement which permits angular adjustment of a drive head. The coupling clamps two parts of the handle shaft together, preventing rotation of one part and permits the selectable rotation of the other. The coupling comprises a split clamp joining and securely holding the handle parts in abutment with one part of the handle shaft telescopically interconnecting with the split clamp, and the other part of the handle shaft rotatably interconnecting with the split clamp in any one of a plurality of alignments. A releasable fastener permits loosening of the split clamp to allow rotational adjustment of the parts and their retention at a selected orientation.
Claims11
A handle held elongated power driven implement having a handle shaft formed by first and second separable and engagable handle shaft parts, a drive head mounted at the distal end of said first handle shaft part, an engine mounted at the distal end of said second handle shaft part, and means for operatively joining said engine to said drive head, the improvement comprising:
- a releasable coupling means for joining the other ends of said first and second handle shaft parts together;
- said releasable coupling means being constructed so that the other end of one of the handle shaft parts is positionable independently of and interlocking with the other end of the other of said handle shaft parts and comprising a split clamp surrounding and securely clamping the other ends of the juxtapositioned handle shaft parts in abutment with each other;
- said coupling means being provided with a stop means on its internal periphery;
- one of the other ends of the handle shaft parts being provided with a slot extending longitudinally inwardly thereof for telescopically engaging with said stop means when engaging with the other end of the other handle shaft part within said coupling means;
- and
- fastening means for releasably clamping said split clamp around the abuting ends of said first and second handle shaft parts.
