Abstract:
A rotary clamp comprising:means for converting linear actuator motion between a first position and a second position into rotary motion of a clamp arm between an unclamped position and a clamped position, respectively; a housing having said converting means disposed therein and a shaped aperture formed therein; a substantially cylindrical member having a longitudinal axis and a shaped surface for matingly engaging said shaped aperture in said housing or in a portion of said housing defining said shaped aperture engages said shaped surface to prohibit rotational movement of said cylindrical member about said longitudinal axis; and said cylindrical member having an eccentric outer portion relative to said longitudinal axis for engaging said converting means in said clamped position to prohibit said converting means from moving beyond said clamped position, and said eccentric outer portion creating a plurality of predetermined radial distances from said longitudinal axis to said outer portion corresponding to predetermined rotational positions of said shaped mating surface within said shaped mating aperture, wherein said predetermined radial distances correspond to predetermined incremental angular adjustments of said converting means in said clamped position.
