Abstract:
1. A bead crimping tool suitable for crimping a bead element, the tool comprising: a base handle comprising a crush plate member adapted to seat the bead element; a pair of opposed pincer members positioned on opposite sides of the crush plate member, at least one of the pincer members pivotally mounted to the base handle; an actuator handle member pivotally mounted to the base handle, the actuator handle member comprising a cam portion engageable with the at least one pivotally mounted pincer member, an actuator portion, and a lever arm portion; a crush arm member pivotally mounted to the base handle, the crush arm member comprising a head portion and a tail portion engageable with the lever arm portion of the actuator handle, the crush arm member biased to cause the head portion to exert a holding force on the bead element seated on the crush plate member; and the actuator handle adapted to first cause the cam portion of the actuator handle to pivot the at least one pivotally mounted pincer member during actuation of the actuator handle so as to impart a lateral compressive force to a lateral portion of the bead element, the lateral compressive force being sufficient to collapse the bead element in a lateral direction, and the actuator handle adapted then to cause the lever arm portion to engage the tail portion and urge the head portion of the crush arm to impart a longitudinal compressive force about a top portion of the bead element, the longitudinal compressive force sufficient to compress the collapsed bead element in a longitudinal direction.
