发明名称 BOARD PRESS
摘要 A board press (10) comprises a dog member (12) dimensioned and configured to grip a joist (14a) and a lever (16) attached to one end to the dog member (12) by a ball and socket mounting (18) for pivoting of lever (16) about a pivot axis P-P. The ball and socket mounting (18) enables the pivot axis to be angularly displaced about a point on pivot axis P-P, thereby permitting the user to pivot the lever (16) perpendicularly to the edge (27) of a board (26a) being pressed despite twisting of the dog member (12) on the joist (14a) during use. A method of pressing one or more boards disposed on a joist includes using the board press and pivoting the lever in a pivot plane which is kept perpendicular to the edge of the board while simultaneously twisting the dog member to seat it upon the joist.
