Abstract

1,164,731. Cam mechanism. BRITISH BROADCASTING CORP. 15 Jan., 1968 [30 Jan., 1967], No. 4447/67. Heading F2K. Equipment is mounted in a housing 1 by four cam plates 2 pivotally mounted on axes O upon the housing walls, the plates 2 having curved cam profiles 3 upon which bear four roller cam followers 4 which are mounted upon the equipment. The cam plates 2 are coupled together by a tray 5 which is acted upon by springs 6 connected at one end 10 to the tray 5 and at the other end 11 to the housing 1. The arrangement is such that in the rest position shown, the spring tension causes the cam plates 2 to exert on the cam followers 4 an upward force a little less than the weight of the equipment. When a small forward and upward force is applied to the equipment, the spring force causes the cam plates to rotate and the rollers 4 roll along the cam profiles 3, lifting the equipment and carrying it forward. The rollers 4 are brought to rest by depressions 7 in the cam profiles and positive stops 12. Rotation of the cam plates 2 is limited by stops 8 fixed to the housing 1. Suitable cam shapes are specified.
