Claim 3:
4. The adjustable weight lifting device as set forth in claim 3, further comprising
a cam knob having an exterior surface that varies between a first distance from an axial center of the tube and a second distance from the axial center of the tube, the second distance being greater than the first distance, the cam knob being attached to and rotatable with the axially inner portion and at least partially disposed inside the axially outer portion,
one or more lateral pins spring mounted inside the axially outer portion and urged against the cam knob and adapted to be moved radially against a spring force out of one or more corresponding holes in the axially outer portion when in contact with a portion of the exterior surface of the cam knob that is at the second distance and to be retracted radially inward of the axially outer portion under the spring force when in contact with a portion of the exterior surface of the cam knob that is at the first distance, and
a butterfly weight disk having a recess extending radially inward from a periphery of the butterfly weight disk in which the axially outer portion is adapted to be received and to be radially movable relative to the housing when the one or more lateral pins are retracted radially inward of the axially outer portion, the butterfly weight disk comprising one or more radially extending openings arranged to receive the one or more lateral pins when the one or more lateral pins are moved radially out of the one or more corresponding holes so that radial and axial movement of the butterfly weight disk relative to the axially outer portion is prevented.
