Abstract:
Exemplary embodiments provide a foldable grappling device comprising a shank or crown having a hollow tubular shaft member and a telescopic slide bar slidably coupled within the hollow tubular shaft member. The device further includes a plurality of foldable grappling arms attached to a base of the shank or crown and a plurality of linking arms coupled to the telescopic slide bar to push the grappling arms to an unfolded position from a folded position or pull the grappling arms to the folded position from the unfolded position. Raising the telescopic slide bar within the hollow tubular shaft member unfolds the foldable grappling arms simultaneously and when lowering the telescopic slide bar, the foldable grappling arms are folded simultaneously.
