DEVICE TO INSTALL SHEET ON CEILING Russian patent published in 2014 - IPC E04F21/18 

FIELD: construction.

SUBSTANCE: device for installation of a sheet on a ceiling comprises a horizontal support platform and a mechanism of sheet supply with a telescopic support. The sheet feeding mechanism is made in the form of two telescopically sliding frames along length, with the possibility of fixation in intermediate positions, and the frames are hingedly mounted on the horizontal support platform on one horizontal axis, with the possibility of rotation in the vertical plane. The frame is made as capable of rotation and resting with an upper end against a vertical support, is "П"-shaped, and the frame made as capable of rotation in the vertical plane between the horizontal support platform and "П"-shaped frame, is H-shaped, including mounted rollers on free ends, with the possibility of fixation in intermediate positions on the horizontal support platform with the help of a stop mechanism. The stop mechanism includes brackets on axes mounted hingedly at both sides of vertical stands of the H-shaped frame, connected with the common horizontal cross-piece, with the help of synchronous rotation relative to axes in the vertical plane and interaction by toothed surfaces with fixators, having limiters, made at both sides on the horizontal support platform. Besides, inclination of teeth on toothed surfaces of brackets is made towards the horizontal support platform.

EFFECT: increased efficiency in operation due to simplified design.
