Abstract
A hand-held can opener is provided with a grip handle, a grip block pivotally mounted to the forward end of the grip handle, a scissor handle pivotally mounted to the grip block and having a one way roller clutch connection with a unidirectionally driven feed wheel. The grip block is provided with a latch. Squeezing of the scissor handle toward the grip handle with pivot the grip block to position the feed wheel relative to the cutter for penetration of the can lid and lock the grip block into this position. Subsequent release and squeezing of the scissor handle will drive the feed wheel undirectionally for advancing the can lid past the cutter.
Claims18
A hand-held can opener, comprising:
- a scissor handle;
- a grip block, said scissor handle being pivotally mounted on said grip block, said grip block having a can rim feed wheel and a latch;
- a one-way clutch connected between the feed wheel and the scissor handle for rotating the feed wheel in one direction only with each pivotal swing of the scissor handle;
- a grip handle pivotally secured to the grip block but not to the scissor handle and having a freely rotatable cutter and a keeper releasably lockingly engageable by said latch for locking the feed wheel adjacent to the cutter;
- and
- a return spring for separating the scissor handle and the grip handle for allowing oscillation of the pivotal movement of the scissor handle by a repetitive squeezing motion.
A hand-held can opener having a first handle having forward and rearward ends, can rim gripping means having forward and rearward ends with the forward end being pivotally mounted on the forward end of the first handle;
- a second handle having forward and rearward ends with said forward end being pivotally mounted on the can rim gripping means;
- abutment means on the second handle engaged with the can rim gripping means for pivoting the gripping means into a can rim gripping position on said first handle, said gripping means including a unidirectionally driven feed wheel and
- said first handle having a cutter, latch means on said gripping means for holding the gripping means onto the first handle with the feed wheel and cutter operatively overlapping in a can lid cutting position whereby initially pivoting the second handle toward the first handle will swing the gripping means into a releasably latched can rim gripping and can lid cutting position, while subsequent pivoting cycles of the second handle will rotate the can feed wheel unidirectionally to advance the can past the cutter.
