ABSTRACT:
A pivot-joint construction for a binocular telescope wherein each telescope ube is pivotable for adjusting the interocular distance between the tubes is provided. Required friction between hinged telescope tube and connection bridge elements is provided by hinge friction tabs stressed in the direction of the axis of the hinge. The tube and the bridge include at least two outer pairs of cooperating non-tensioned hinge tabs having axial holes therein for retaining a hinge pin. A pre-stressed spring is disposed on a central hinge tab of one element about the pin between cooperating tabs on the other element for stressing in the axial direction so that the interocular distance of the telescope will remain set without disturbing the required parallelism between the telescope tubes. The construction is particularly well suited for binocular telescopes fabricated from synthetic materials.
