Ratcheting tool with angular positioning handles for cutting non-metal pipe and tubing

摘要

Disclosed is an improved pipe cutting tool based upon a ratchet closure action wherein handles are pivotedly attached to allow successive movement of a cutting blade in response to the squeezing of the handles. The handles are also hingedly coupled to the cutting member to maintain the cutting member in a position perpendicular to the tubular item to be cut while allowing the operator to squeeze the handles at offset angles, up to and including a right angle cut. The hinged handles allow for offset operation without forgoing the ease of operation by the consumer or causing a large reduction in the mechanical advantage. A ratchet allows sequential advancement of a cutting member toward a tubular shaped jaw that holds the item to be cut.

主权项

1. A tool for cutting non-metal pipe or tubing comprising:
a base member formed from a rigid S-shaped support section having a tubular shaped jaw along a first end for receipt of tubular items to be cut and a second end; a first handle having an upper end secured to said second end of said base member for rotation about a pinion pin member, said pinion pin member providing single axis rotation of said first handle with respect to said base member, and a lower grip end positioned substantially parallel to said tubular shaped jaw; a second handle secured to said first handle for rotation about a pivot, said pivot being positioned at central portion of said second handle and oriented substantially perpendicular with respect to said pinion pin member; a coupling post having a first end and a second end, said first end pivotally secured to said base member via an engagement rivet, said engagement rivet oriented to be substantially parallel to said pivot, said second end secured to a first end of said second handle via a spherical coupler; a cutting member pivotally secured to said base member; and a ratchet means allowing sequential advancement of said cutting member toward said tubular shaped jaw; wherein the sequential squeezing of said first and said second handles causes the pivotal movement of said cutting member over said tubular shaped jaw for cutting of a tubular shaped item placed therebetween.
