Patent

CA 2558504

The adjustable wrench has two wrench elements (8,9) each having a jaw portion (8) and a body portion (9), each body portion having angled tongues (42) and grooves (40), slideably mounted opposite one another with the jaw portions opposing each other. Between the two body portions is an actuator (20,22,24) with a plate (22) having two sides. Each side has angled tongues (42) and grooves (40) corresponding to and slideably engaging the angled grooves of each of the body portions. The actuator moves along a longitudinal axis (5) of the handle thereby urging the wrench elements and jaws towards and away from one another depending on the direction of movement of the actuator, by interaction of the inclined grooves, acting as wedges using the inclined plane principle.

La clef réglable selon la présente invention comprend deux éléments constitutifs (8,9) qui comportent chacun une partie mâchoire (8) et une partie corps (9), chaque partie corps étant pourvue de languettes inclinées (42) et de rainures (40) installées coulissantes en face l'une de l'autre alors que les parties mâchoire sont opposées entre elles. Entre les deux parties corps se situe un élément d'actionnement (20, 22, 24) comportant une plaque (22) présentant deux côtés. Chaque côté est doté de languettes inclinées (42) et de rainures (40) correspondant aux rainures inclinées de chacune des parties corps, dans lesquelles elles sont en contact coulissant avec lesdites rainures inclinées. L'élément d'actionnement se déplace sur un axe longitudinal (5) du manche, ce qui sollicite ainsi les éléments et les mâchoires de la clef dans le sens du rapprochement ou de l'éloignement en fonction du sens de déplacement de l'élément d'actionnement, du fait de l'interaction des rainures inclinées, qui font office de coins selon le principe du plan incliné.
