Abstract (en)
[origin: JPH02136403A] PURPOSE: To enable a basic plank to be enlarged on each side to the half by connecting an extensible plank to an auxiliary cheek close to an inner movable cheek, and guiding and holding the auxiliary cheek by a guide means extensibly fixed on the outside parallel to a cylinder axis. CONSTITUTION: A telescopic cylinder 3 to extend an extensible plank 4 is fixed to each side end of a central cheek 2, and an outer movable cheek 5 and an inner auxiliary cheek 6 connected to the telescopic cylinder 3 are provided on the extensible plank 4. An inner movable cheek 8 and an outer movable cheek 5 are connected by an expansion rod 7, and a guide rod 13 parallel to an axis of the telescopic cylinder 3 or a guide member similar to that is fixed to the inner movable cheek 8. By an auxiliary cheek 6 guided by the guide rod 13, the extensible plank 4 can be extended to a width of roughly half that of a basic plank 1.
