An optical sight (30) is affixed to a rail (26) on a receiver (22) of a weapon (20) by a torque-limiting weapon mount (40). Force is applied to clamp the optical sight (30) to the rail (26) by the relative movement of two inclined ramps (58, 72), one on a rotating knob (44) and the other on a nut (42)whose turning generates the clamping force. The torque, and thence the force, that can be applied in attaching the optical sight (30) is limited by the selection of a spring (102) and by steps (64, 78) at the ends of the two inclined ramps (58, 72) that prevent a clamping force greater than that permitted by the spring(102) force when the knob (44) is turned.
Cette invention concerne un mécanisme limiteur de couple (40) servant à monter une lunette de tir (30) sur un rail (26) disposé sur la carcasse d'une arme à feu (20). La force de serrage de la lunette de tir (30) sur le rail (26) est déterminée par le mouvement relatif de deux rampes inclinées (58, 72), une ménagée sur un bouton tournant (44) et l'autre sur un écrou (42) dont la rotation développe la force de serrage. Le couple et, partant, la force de serrage sont limités par la raideur du ressort (102) choisi et par les gradins (64, 78) prévus au bout des deux rampes (58, 72) et ayant pour rôle d'empêcher une force de serrage supérieure à celle permise par le ressort (102) sollicité à la rotation du bouton (44).
