(EN) TOGGLE OPERATED CLAMP
(FR) BRIDAGE A GENOUILLERE
Abstract
(EN)
Juxtaposed-links differential toggle linkages as used hitherto on industrial clamps usually apply toggle pressure to a straight clamp bar sharing pressure between a fixed fulcrum pin and the clamping end of said bar, or else use a cranked clamp bar with arm lengths fixed by overall height of clamp, and having the short toggle link and handle pivotally fixed to clamp body. This invention concerns a toggle clamp having a juxtaposed-links differential toggle linkage to actuate near end of adjacent clamping bar (8), said bar (8) having a fulcrum element (10) intermediate said linkage and the remote clamping end (9) of said bar with, on manually operated clamps, the optional use of quick release/retention slots (11) for fulcrum element (10) and clamp bar, plus slot/s (14) in clamp base for rapid set-up/removal of clamp.

Les chainages a genouillere differentielle a tiges d"assemblage juxtaposees utilisees jusqu"a present dans les bridages industriels appliquent habituellement une pression articulee sur une barre de bridage droite qui decompose la pression entre un axe pivot et l"extremite de bridage de ladite barre ou bien ils utilisent une barre de bridage coudee avec des bras fixes sur la hauteur de la bride et ayant la tige d"assemblage courte et la poignee fixee de maniere pivotante sur le corps de bridage. Cette invention concerne un bridage a genouillere ayant un chainage a genouillere differentiel a tiges d"assemblage juxtaposees pour actionner l"extremite proche de la barre de bridage adjacente (8), ladite barre (8) ayant un element a pivot (10) entre ledit chainage et l"extremite de bridage distante (9) de ladite barre avec, sur les brides a fonctionnement manuel, la possibilite d"utiliser des fentes a deblocage/retenue rapide (11) pour l"element a pivot (10) et une barre de bridage plus des fentes (14) de bridage pour le serrage/desserrage rapide de la bride.
