Patent number: 11953808Abstract: A mounting system for an image capture device that includes three pivotably connected arms is disclosed. The first arm includes a first fastener that is lockable and unlockable to allow for connection and disconnection of the image capture device, and a second fastener that is lockable and unlockable to regulate the position of the image capture device relative to the first arm. The mounting system further includes a third fastener that is lockable and unlockable to regulate the relative positioning between the first arm and the second arm, and a fourth fastener that is lockable and unlockable to regulate the relative positioning between the second arm and the third arm. Whereas the first fastener is removable, each of the second, third, and fourth fasteners is captive to (nonremovable from) the mounting system.Type: GrantFiled: September 9, 2021Date of Patent: April 9, 2024Assignee: GoPro, Inc.Inventors: Huy Phuong Nguyen, Bessy Liang, John George Muhlenkamp, IV, Scott Alberstein, Joshua T.
