  • Patent number: 9753483
    Abstract: A click knob assembly that has a fixture having a circular inner surface defining uniformly spaced ridges separated by grooves and a knob, set in the fixture, and including a user accessible portion; a spring holder, attached to the user accessible portion; a spring assembly, engaged to the spring holder; and a first plunger and a second plunger engaged to the spring holder, each facing the circular inner surface, in opposed direction to each other, and each being pushed outwardly by the spring assembly, and thereby being pressed into the circular inner surface. The first plunger includes a click surface sized and positioned to engage the uniformly spaced grooves. When the knob is rotated, the click surface is pushed over a ridge, and then falls into a groove, making a click sound and both the plungers are maintained in contact to the circular inner surface by the spring assembly.

  • Patent number: 5671088
    Abstract: The present invention provides an erector system characterized by centered erector lenses and lens holder movement capability to alter relative erector lens placement. Alignment of the erector lens optical centers facilitates the reduction of the phenomenon of trackout. Alteration of relative erector lens position permits a pistol scope or another device embodying the erector system to operate at more than one magnification.
