  • Patent number: 6517224
    Abstract: An integral constant tension rotation stop for a lighting fixture includes an aiming arm, a lamp retaining member, a lamp retaining arm, a rivet and a tension washer. The aiming arm includes an end having an opening. The lamp retaining member receives a lamp and includes an opening and a slot. The lamp retaining arm retainer is a lamp against the lamp retaining member and includes an opening and a tab configured to pass through the slot in the lamp retaining member. The rivet has a head and a shank having a first end extending from the head to a second end. The tension washer has an opening. The shank passes through the opening in the aiming arm, the opening in the tension washer, the opening in the lamp retaining member, and the opening in the lamp retaining arm. The rivet is riveted in place such that the tension washer is under compression and rotation of the aiming arm is limited by the tab.
