  • Arrangement of cylinder elements for a lens barrel
    Patent number: 4297002
    Abstract: An arrangement of cylinder elements for a lens barrel includes a first cylinder element and a second cylinder element which is coupled to and carried within the first cylinder element. An annular ridge portion is carried on an outer peripheral surface of either the first or the second cylinder element. The peripheral surface which carries the annular ridge portion faces an outer peripheral surface of the other cylinder element. A reinforcing member is attached to the annular ridge portion for reinforcing the strength characteristics of the cylinder elements. The reinforcing member is annularly shaped and is made of a material which is stronger than the material of the cylinder element which carries the annular ridge portion to thereby structurally reinforce this cylinder element and prevent deformation of the cylinder elements upon the application of external forces.
