The closing-opening unit is designed to open the doors of dwelling-houses, service spaces and strongboxes. The aim of the invention is: the fingers inside of the unit are tightly fixed to the disk perpendicularly to its surface, on the plain side of each of the puller, mounted on the disk there is a tracking notch (8), into which an axis (2) is placed. The longitudinal axis (9) of this notch is parallel or corresponds to the longitudinal axis (10) of the puller. Each of the mentioned tracking notches (11) is used for the placement of the fore mentioned finger, is made on the plain side of each puller, the longitudinal axis (12) of this notch (11) is perpendicular to the longitudinal axis (10) of the puller. When the closing-opening unit is in a fully closed position, the mentioned finger corresponds to the end of the tracking notch (11), which is closer to the longitudinal axis (10) of the puller. The fingers in the plane of the disk are positioned in such way, that the angles (α) between the lines, connecting the axis of the neighbouring fingers with the mentioned axis (2), fixed to the still plane base, are equal to the angles (β) between the longitudinal axes (10) of the corresponding pullers, and the distance between the fingers and the axis (2), fixed to the still plane base is selected in such way, that it can not disturb the sliding movement of the pullers. The tenon of the lock is connected to one of the pullers, one or more supplementary disks can be mounted on the mentioned axis (2), that would be parallel to the mentioned disk and tightly connected together and with the disk, and the mentioned pullers are mounted on disks. |
