Definitions

  • Pliers are used in conditions that can be cramped and restrict an operator's freedom of movement of hands, arms and body. It can be quite difficult to use pliers under such conditions. For example, residential plumbers installing sinks under countertops, commercial plumbers on ladders installing water pipe fittings in ceilings of buildings, and mechanics working on automobiles all can encounter problems accessing workpieces with pliers and can find it difficult, problematic or not possible to use pliers in many circumstances.
  • Some pliers can have two handles joined by a fulcrum and the operator uses both hands to manipulate and adjust the relative positions of the handles to prepare the pliers for use on a workpiece. The requirement that two hands be used to adjust such pliers poses a significant problem for operators and a failure of hand tool technology. There is a strong need to develop pliers having an improved system for changing the relative positions of the handles.
  • Pliers also known as gripping pliers, are a type of hand tool commonly used by tradesmen for firmly holding or moving a work piece.
  • the pliers can include handles and jaws configured to move about a fulcrum, such as a pivot lock.
  • a handle length can be longer than a jaw length and the pliers can be configured to apply high leverage to a work piece when gripped by the pliers.
  • a hand tool can have a slide bar which has a slide jaw and a slide jaw handle, as well as a base bar which has a base jaw.
  • a pivot lock can pivotally connect said slide bar to said base bar.
  • a push- lock actuator can be configured to reversibly move said pivot lock to achieve a reversibly locked state or a reversibly unlocked state.
  • the pivot lock can have a pivot lock opening through which at least a portion of the pivot lock passes.
  • a force can be applied to at least a portion of the push-lock actuator to achieve the reversibly locked state or the reversibly unlocked state.
  • the pliers can have the slide bar, the base bar and a push-lock which can have a pivot lock pivotally connecting the slide bar and the base bar.
  • the pivot lock has an engaged state when said push- lock is in a locked state and said pivot lock has a disengaged state when said push-lock is in an unlocked state.
  • the push-lock can have a push-lock actuator which has at least one actuator hinge which can rotate radially about at least a portion of a pivot axis of a slide bar hinge member.
  • the push- lock actuator can be configured to engage a portion of the pivot lock.
  • the push- lock actuator can impart a motive force to the pivot lock when the push-lock actuator is moved.
  • the pliers can be adjustable pliers and can have a distance between jaws, which is a jaw opening distance.
  • the opening range of the jaw opening distance can be from a maximum jaw opening distance to a minimum jaw opening distance.
  • the adjustable pliers can have with multiple discrete reversibly lockable positions within the jaw opening range. In use, the relative position of the jaws can be locked in any number of discrete positions along the opening range.
  • the technology herein achieves the result that the pliers can be directly adjusted to any position in the opening range by a one-handed operation by an operator. The technology allows the operator to adjust the jaw opening distance to a larger or smaller distance by as little as one lock increment, such as one lock tooth on a slide bar.
  • the adjustable pliers can be adjusted with one-hand to adjust the jaw opening distance to properly fit a work piece without having to engage in unwanted actions, or to fully opening the pliers prior to adjusting, or removing the pliers from the work piece to make an adjustment of the jaw opening distance.
  • the technology disclosed herein achieves the capacity for an operator to make small or large adjustments of the jaw opening distance which increase or decrease the jaw opening distance in an ergonomic, efficient and controlled manner, providing ease of use and eliminating guesswork in executing a desired adjustment.

Abstract

La présente invention concerne une pince réglable comportant un verrou-poussoir qui permet d'obtenir une capacité de réglage d'une main de la séparation des mâchoires de la pince par un opérateur. La pince réglable peut comporter une barre coulissante et une barre de base assemblée par un verrouillage à pivot. La pince réglable peut comporter un actionneur de verrou-poussoir sur la barre coulissante au moyen duquel un opérateur peut changer de façon réversible l'état du verrou à pivot d'un état verrouillé à un état déverrouillé en utilisant une seule main et permettant à l'opérateur d'ajuster la position de la barre coulissante par rapport à la barre de base lorsque le verrou-poussoir est dans l'état déverrouillé.
