FUR COUPLING FOR SNIPER HAND HEAT INSULATION WHEN FIRING A SNIPER RIFLE Russian patent published in 2020 - IPC F41H3/00 

FIELD: clothes.

SUBSTANCE: invention relates to winter outer clothes and, in particular, to systems for protection of sniper hands against frostbite during firing from sniper rifle and is intended for heat insulation of hand sniper hand at prolonged waiting, aiming and execution of several shots in frost. Technical result is achieved by that the upper part of the right side wall of the coupling is made with a through shaped incision, which in the operating position of the coupling in the area of the projection of the sleeve-opening window and the trajectory of reciprocal movement of the handle of the rifle arm forms in the wall a flap of elongated shape with rounded angles and with a base, providing external flap deflection upward and simultaneous opening in wall of hole having length and width exceeding by 6–12 mm accordingly distance between maximum remote points of trajectory and window and distance between lower and upper edges of window, as well as due to the presence of a cast plastic permanent zip tape, made in a structural modification of type "A", sewn by its side edges, respectively, to free edges of the flap and a hole, providing multiple attachment to each other and their detachment, and due to the presence of belts firmly attached by their ends to the external surface of the flap in the front and back parts thereof perpendicular to its longitudinal axis and in direction from it, providing reliable fixation of the flap in the bent position.

EFFECT: device ensures heat preservation in fingers of working hand at long-term waiting, sighting and multiple firing at frost and ejection of shell cases from rifle beyond confines of coupling.
