  • the plurality of tool components 224 include a bottle opener, pry bar, bit driver, file, and scissors.
  • the term “coupled” means the joining of two components directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature.
  • the relative dimensions, including angles, lengths and radii, as shown in the Figures are to scale. Actual measurements of the Figures will disclose relative dimensions, angles and proportions of the various exemplary embodiments. Various exemplary embodiments extend to various ranges around the absolute and relative dimensions, angles and proportions that may be determined from the Figures. Various exemplary embodiments include any combination of one or more relative dimensions or angles that may be determined from the Figures. Further, actual dimensions not expressly set out in this description can be determined by using the ratios of dimensions measured in the Figures in combination with the express dimensions set out in this description.

Abstract

Un outil à main, tel qu'un outil polyvalent comprenant des poignées pivotantes, est présenté. L'outil polyvalent comprend une première et une seconde poignée, une première et une seconde partie de mâchoire, accouplées aux première et seconde poignées, et une pluralité de composants d'outil. L'outil polyvalent comprend en outre un mécanisme de verrouillage qui comprend un élément de mise en prise, une broche et un élément de sollicitation. Lorsque la première ou la seconde poignée est dans une position verrouillée, l'élément de sollicitation applique une force poussant la broche en prise avec l'élément de mise en prise pour fixer la première ou la seconde poignée. Lorsque la première ou la seconde poignée est dans une position déverrouillée, la broche est mobile le long de l'élément de mise en prise de telle sorte que la première ou la seconde poignée peut pivoter. Dans un mode de réalisation spécifique, l'outil polyvalent comprend un mécanisme de pré-déploiement conçu pour déployer le composant d'outil à divers angles, ce qui permet d'améliorer l'accès et l'ouverture des composants d'outil.
