Description

The invention relates to the field of building: sliding doors (gates) with a drive, both mechanical and manual. A device for opening sliding doors, comprising a drive and a troso-block system, is known. However, this device does not allow manual opening of the door. The purpose of the invention is to provide the possibility of manually controlling the door leaf in the event of an emergency. This is achieved by the fact that a drum is fixed on the door leaf, to which the safety coils of the cable are attached to us, equipped with a brake, kinematically connected with a door handle. FIG. 1 shows the proposed device for opening sliding doors (gates); in fig. 2 is a section along A-A in FIG. 1; in fig. 3 - a section lo B - B in FIG. 2. The device for opening the sliding doors (gates) includes a closed branch of the cable 1, the envelope of the barcan hivivoda 2, the guide blocks 3-7 and the drum 8, mounted on the canvas of the door 9, open on the rollers 10 along the guides 11,: Drum, mounted on the door leaf, provided with a brake 12, spring 13 pressed and an eccentric controlled from the door handles 14. On the drum 8, the cable has several safety turns that prevent it from slipping. The work is carried out as follows. Getting movement from drive 2, cable 1 moves the door leaf 9 to the right or left, as drum 8 is constantly braked by brake 12. When the door handles 14 are acting through eccentrics 15, brake 12 releases drum 8, which gets a possibility of rotation. The door leaf is freed from the rigid joint ;: neither: with the driven cable, it is able to roll away freely. ..
