Patent number: 9831819Abstract: A rotating, pivoting mount for mounting a panel is disclosed. The mount can include a mounting block, a driveshaft, and a base. A socket in the mounting block can be mounted on a ball of the base to pivotally couple the panel to a structure. The ball can also include a cam profile, while the mounting block can include a complementary cam follower. As the mounting block rotates, therefore, the cam follower can follow a path set forth by the cam profile to tilt the mounting block about one axis as the mounting block rotates about a second axis. In this manner, the panel can be rotated and tilted—or moved about two axes—using a single motor. The use of a single motor can, in turn, reduce the cost and complexity of the system, while maintaining high efficiency for the panel (e.g., a solar panel) mounted thereon.Type: GrantFiled: March 24, 2016Date of Patent: November 28, 2017Assignee: KIRK-RUDY, INC.Inventors: Harry V. Kirk, Bryan Carbon, Wolfgang G. Fraint, Michael Aiken
