Coupling device for a camera
Abstract
Abstract A DEVICE FOR COUPLING A PAIR OF MOVBLE MEMBERS, PARTICULARLY A PAIR OF CONCENTRICALLY ORIENTED, ROTATABLE MEMBERS, INCLUDES A STUD HAVING A CYLINDRICAL MAIN PORTION ROTATABLY MOUNTABLE IN ONE OF THE MEMBERS AND A CONICAL ECCENTRIC PORTION FIXED TO THE CYLINDRICAL MAIN PORTION FOR ROTATION WITH THE MAIN PORTION TO A POSITION OF COUPLING ENGAGEMENT WITH THE OTHER OF THE MEMBERS. IN THE ILLUSTRATED EMBODIMENT, THE ON MEMBER IS THE SETTING RING AND THE OTHER MEMBER IS THE LENS BARREL OF A PHOTOGRAPHIC OR CINEMATOGRAPHIC CAMERA. THE STUD IS RECEIVABLE IN A RADIAL, SMOOTH-BORED HOLE IN THE SETTING RING, AND THE CYLINDRICAL MAIN PORTION IS SKEWED IN THE HOLE WHEN THE CONICAL ECCENTRIC PORTION IS ROTATED TO A POSITION OF COUPLING ENGAGEMENT WITH A MATING SURFACE ON THE LENS BARREL. THE STUD IS PREFERABLY MADE OF AN ELASTIC PLASTIC MATERIAL, SO THAT THE CONICAL ECCENTRIC PORTION IS DEFORMABLE BY SERRATIONS ON THE MATING SURFACE OF THE LENS BARREL TO PREVENT ACCIDENTAL REVERSE ROTATION OF THE STUD AND CONSEQUENT UNCOUPLING OF THE TWO MEMBERS.
