APPARATUS FOR FIXING OPTICAL SIGHTING DEVICE Russian patent published in 2014 - IPC G02B27/00 

FIELD: physics.

SUBSTANCE: apparatus for fixing an optical sighting device consists of a mounting plate 1 on which there are opposite blind-end graded slots 2. Supports 4 are mounted in the slots 2 such that they are able to rotate on axes 3, said supports having a radius surface 5 on which there are liners 6 made of elastic material, the outer side of which has a slant 7. The axes 3 are mounted in slots 8 perpendicular to the graded slots 2 and are fixed with screws 9. In the graded slots 2 under the supports 4, there are plate springs 10, one end of which forced into a cut 11 made in the step 12 of the slot 2 and the other rests on the edge of the supports 4.

EFFECT: fast and reliable fixing of the device when switching the device from a working position to a stowed position and vice versa.
