Cremone 1

Описание к видео Cremone 1

Ellipse knob is linked by a rack and pinion gear to a pair of half-round rods which slide over the outside surface of the door or window and extend into sockets at the head and sill of the opening. The gear mechanism operates the two vertical rods at the same time; one rod extends up into the door head, and the other extends down into the door sill.
