A bulk bag support for filling wherein the bulk bag has plural handles spaced around a top perimeter thereof. The support includes a frame and an elevatable mounting platform mounted on the frame. A plurality of spaced, openable and closeable support hooks are provided on the mounting platform and are selectively activatable for movement between opened and closed positions for selectively gripping and releasing the aforesaid handles. The support hooks, when in the closed position, releasably grip the handles thereby causing the bulk bag to be suspended from the support hooks and, when lifted, above a base member of the frame and to facilitate is filling of the bulk bag. When the support hooks are in the opened position, the handles on the bulk bag are thereby released causing the bulk bag to rest on the aforesaid base member. A yieldable biassing spring is provided for continually urging the support hooks toward the closed position.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A bulk bag support for filling, said bag having at least a bottom wall extending upwardly from a perimeter of the bottom wall and a sidewall terminating in a top perimeter and plural handles spaced around the top perimeter, comprising:a frame, said frame including a ground engaging base adapted to engage the bottom wall and support the bulk bag during and after a filling thereof and an upstanding column;a mounting platform on said frame and overlying said base;a plurality of spaced support means on said mounting platform, each of said support means including selectively actuable means supported for movement between first and second positions for respectively selectively gripping and releasing said handles, said selectively actuable means, when in the first position, non-releasably gripping said handles thereby causing said bulk bag to be suspended from said support means and above said base for filling and, when in the second position, releasing said handles thereby causing said bulk bag to rest on said base, wherein said selectively actuable means includes a bracket mounted on said mounting platform and a hook member pivotally mounted on said bracket and adapted to grippingly engage and release said handles, said hook member including an arcuately shaped, upwardly facing handle engaging surface having a distal end juxtaposed said bracket when said selectively actuable means is in the first position to thereby prevent the handle passing therebetween, a center of said arcuate handle engaging surface approximating a pivot axis for said hook member so that when a weight force from said bulk bag is applied to the handles, a theoretical vector of the force will be transmitted through said bracket adjacent said pivot axis; andyieldable biassing means for continually urging said selectively actuable means toward said first position.
