Title (EN) WRENCH
(FR) CLE A VIS
Abstract:
(EN) A wrench for holding one fastener element of a nut-and-bolt fastener against rotation while the other fastener element is turned to tighten or loosen the fastener. The wrench comprises a wrench plate (9) having a plurality of different size openings (27) for fitting fastener elements (e.g., the bolt) of different sizes, the wrench plate being engageable with an adjacent part (P) when the other fastener element (e.g., the nut) is turned for holding the one fastener element against rotation, and a resilient material (15) affixed to one face of the wrench plate, the resilient material projecting a relatively small distance beyond an edge of each opening for resilient engagement by the one fastener element (e.g., the bolt) when the latter is fitted into the opening. The resilient engagement of the fastener element and the resilient material holding the wrench plate in a fixed, self-retaining position with respect to the one fastener element prior to turning the other fastener element whereby both hands may be used to turn the latter for tightening or loosening the fastener.
(FR) Une clé à vis qui serre un élément de fixation faisant partie d'u ensemble de fixation formé d'un écrou et d'un boulon, de façon à l'empêcher de tourner lorsque l'on visse l'autre élément de fixation afin de serrer ou de relâcher l'ensemble de fixation, comprend une plaque (9) de vissage avec une pluralité d'ouvertures (27) de différentes dimensions qui s'adaptent à des éléments de fixation (par exemple, des boulons) de dimensions diverses. La plaque de vissage peut enclencher une partie adjacente (P) lorsque l'on visse l'autre élément de fixation (par exemple, l'écrou), de façon à empêcher le premier élément de fixation de tourner. Un matériau élastique (15) fixé à une face de la plaque de vissage s'étend sur une distance relativement réduite au-delà d'un bord de chaque ouverture, afin d'enclencher de manière élastique un élément de fixation (par exemple le boulon) lorsque l'on introduit celui-ci dans l'ouverture. L'enclenchement élastique de l'élément de fixation et du matériau élastique maintient la plaque de vissage dans une position fixe d'auto-blocage par rapport à l'autre élément de fixation avant que l'on visse l'autre élément de fixation, de sorte que l'on peut utiliser les deux mains pour visser ce dernier afin de serrer ou de relâcher l'ensemble de fixation.
