Abstract
A slingbar includes a sling attachment member and an actuating mechanism. The sling attachment member includes a frame, a portion of which defines an opening, the frame and opening defining an interior of the sling attachment member and a closure element. The actuating mechanism includes a cam and a linkage arranged to be driven by the cam and to operate the closure element in response to motion of the cam thereby causing the closure element to block or expose the opening.
