US Patent 11982483 Ice shaver with multi-link control arm

The present invention provides an ice shaver with a multi-link, self-locking, force-reduction, motion control arm or armature to press an ice block against a blade. The armature has a lever with a forward handle, an intermediate connection to the column, and a rear connection to the frame of the ice shaver. A link is coupled between the rear connection of the lever and the frame of the ice shaver to form a four-bar linkage. The armature has a raised locked configuration in which the lever and the link are oriented substantially co-linear to maintain the column in a raised position. In another aspect, joints between the lever and the column can comprise dampers.
