Abstract
A barbecue tongs is provided wherein the arms are yieldingly outwardly biased. The tongs incorporate an arm pivot limiter for each of outward pivotal movement and inward pivotal movement as well as an arm lock that holds the arms in an almost fully jaws closed configuration for convenient storage. The tongs utilize a slidable U-shaped sleeve at the rear end which can have either one of two positions selected by a user. In one position, the arm lock is operational while in the second position the outward pivot limiter is operational.
Claims10
Tongs for use in barbecuing and the like comprising in combination:
- a pair of elongated arms, one arm extending in adjacent, aligned relationship relative to the other, each arm having a front end portion and an opposed rear end portion;
- said respective front end portions coacting to comprise a pair of jaws that open and close to grasp a selected object;
- said respective rear end portions being pivotably associated together whereby said jaws can advance pivotably towards and away from one another relative to said rear end portions;
- a spring extending between said arms and yieldingly biasing said arms into an outward configuration relative to each other;
- a reversibly actuatable clamp means for holding when actuated said respective jaws in a nearly closed configuration;
- first pivot limiting means associated with said clamp means for limiting maximum outward movement of said jaws relative to one another;
- and
- second pivot limiting means associated with said arms limiting further inward movement of said arms when said jaws are in a substantially fully closed configuration.

Tongs for use in barbecuing and the like having tong clamp means and tong pivoting means, said tongs comprising in combination:
- a pair of elongated arms, one arm extending in adjacent, aligned relationship relative to the other, each arm having a front end portion and an opposed rear end portion;
- said respective front end portions coacting to comprise a pair of jaws that open and close to grasp a selected object;
- said respective rear end portions each having at least one terminal hinge leaf portion, said hinge leaf portions of both arms coacting with one another so that adjacent leaf portion side faces of each respective rear end portion are oppositely pivotable relative to one another about an axis the extends generally normally to said arms whereby said jaws can advance pivotably towards and away from one another relative to said hinge leaf portion;
- a pintle that extends along said axis and that interconnects said hinge leaf members;
- a spring extending between said arms and yieldingly biasing said arms into an outward configuration relative to each other;
- a reversibly actuatable clamp means for holding when actuated said respective jaws in a nearly closed configuration, said clamp means comprising:
- a flange with opposed side faces, said flange rearwardly projecting from said rear end portion of one said arm, and said flange extending along and adjacent to said hinge leaf portions,
- a U-shaped sleeve having opposed respective leg members, said sleeve slidably extending over said flange with each said leg member slidably engaging a different one of said side faces,
- a terminal portion of one said leg member extending into a channel defined between one side face of said flange and said rear end portion of said other arm, said terminal portion being slidably moveable in said channel when said sleeve slidably moves over said flange;
- said one leg member terminal portion and said rear end portion of said other arm cooperating with each other so that
- when said sleeve is in a first position along said flange, and said respective jaws are in said nearly closed configuration, said rear end portion of said other arm abuts against said one leg member terminal portion and said arms are in a clamped together configuration, and
- when said sleeve is in a second position along said flange, and said jaws are pivotable relative to one another, and when said jaws are in a prechosen maximum outwardly divergent configuration, said rear end portion of said other arm abuts against said flange and said jaws diverge only to said maximum divergent configuration;
- and
- a pedestal medially located on each said arm, each pedestal having an outer facial portion configured to abuttingly engage with the other, and each pedestal being in aligned relationship with the other, so that, when said jaws are pivotably advanced to a substantially fully closed configuration, said respective outer facial portions of each pedestal engage, thereby limiting further pivotal closing of said jaws.
