Title: Cylinder lock
IPC: E05B27/00
Filed: 2014-03-19
Abstract: A cylinder lock includes body with long channel and radial recesses, movable body installed in the long channel of the body, core as a spring-supported pusher fixed with a pin in the rotary body installed with possibility of coupled rotation in the long channel of the body, pin stops, retaining washers that hold the inner core, and a pole from long displacement, rotary shaft with bearing element and a pole placed in the inner core as a shaft, this with the side surface interacts with it, opening in the movable body with depression as grooves and recesses for installation and connection to those of the structural elements of the key at the outer side of the lock, coaxial pins and pusher that is connected to the pole, insert placed in the depressions of the movable body with possibility of long displacement and interaction with one of the ends with the key at opening from outside, stop for restriction of stroke of key at placement of this one to the opening for the key, surrounding the pole and installed with rotation with the pusher that interacts with the pole and the level of the lock, this is equipped with the movable body one and the movable body two, a spring installed in the fixed body one, shutoff pusher as a rod-shaft with circular lug as a piston. In the movable body two at least two fixed reading pins are provided, for reading the slots on the cylindrical surfaces of the key. In the second movable body at least two cylindrical circular recesses with given lengths are provided, those are placed eccentrically with respect to the central axis of the second movable body, and by means of those displacement of one with respect to another is provided by pre-set angle for reading with key of grooved surfaces, with correspondence to those recesses on the key at its turn in the openings at least by 360 degrees, in the second movable body, together with insert as a fixed shaft attached to it, volume is formed and cylindrical grooves are provided, those are coaxial to the central axis of the movable body two. In the movable body two rigidly and normally to the axis pins for reading the surfaces of structural key coding are fixed, the movable body two is equipped with a partition in which an opening is provided, there a bearing bushing by type of movable piston is installed, this with the piston sections interacts with the pin that in its turn interacts with the grooves on the cylindrical section of the surface of the insert. The pin is installed in the rod-shaft as rigidly fixed normally to the axis. The pins in the movable body two installed in the partition normally to the axis jointly with radial recesses and grooves of the second movable shaft by given depth and length of the grooves provide interaction with the grooves of the cylindrical surfaces on the key for reading the pressing section of the key at different diameters of the radial surfaces provided, and by the length to the depth of placement of the grooves of the pressing section of the key. In the volume formed with the connection of the second movable body, insert as a fixed shaft and the stop bushing in axial direction a spring-supported shaft-pin moves, its pin interacts with the groove of the insert; in the movable body one by means of pin joint a cover is fixed, to this one at outside a flywheel is attached. On the inner side of the cover of the movable body one a lug is provided, with additional groove with a cross-like slot, there the lug of the rod-shaft can be installed at instant of opening from outside, and at instant of opening/closing from inside of premises force from the flywheel, through the cover and the pin joint of the cover and the movable body one and the pin joint of the last one interacts with the pole that acts on the level of the lock. The spring installed in the cavity of the first movable body with one end interacts with the inner surface of the cover, and with the other one – with the side surface of the lug as a piston on the shaft-rod. The pole is fixed with possibility of rotation on the axle of the shaft-rod. The movable body one and the movable body two are fixed in the body by means of retaining washers, each of those with one side interacts in hinged way with the pole, and with the other one – with the body of the cylinder lock.
