<p>A jaw clamp serves for moving an unsecured board (11;17) transversely along an underlying deck support (8;17) to a predetermined position on the deck support and for straightening warped or bowed deck boards on the deck support. The jaw clamp comprises a first jaw (2) attached to a bar (3), a second jaw (4) attached to a slide (5) on the bar, a handle lever (6) which is mounted on a transverse pivot (32) on the slide and partly is extending into a cavity (23) formed in the slide, a spring loaded ring (25) which is placed in said cavity and is encompassing the bar, and a pressure foot (36) attached to the handle lever for jamming the ring tight to the bar by exerting a pressure upon the ring when pivoting the handle lever. The handle lever is divided up into a first separate lever arm (30) extending into the slide and a second separate lever arm (31) extending outwards from the slide. Each of the two separate lever arms is pivotally mounted upon the pivot, whereby the two separate lever arms have a first and second coupling part (34;39), respectively arranged for coupling the two arms together in at least two mutual angle positions. The handle lever can advantageously be positioned in desired operative angle positions in a plane preferable perpendicular to the deck support.</p> |
