Embodiment Construction

[0033] Referring to FIGS. 2 , 3A, 3B and 4 , the cylinder door lock 10 of the present invention includes a handle assembly 12 , a housing 14 with an outer latch 16 , an inner latch 18 and rotating cam 20 and outer handle 22 . The handle assembly 12 is mounted on the inner pin 18 . The housing 14 and rotating cam 20 are of the size and form of a standard cylinder lock and can be retrofitted in any standard door lock. A standard door lock is latched by a bar which, under the action of a rotating cam 20, slides into a recess in the door frame (lock, bar and frame not shown). In the following, it is assumed that the handle assembly 12 is located on the inside (room side) of the door, while the outer latch 16 and outer handle 22 face outside (hallway or street side).

[0034] The two latches 16 and 18 are rotatably accommodated in the housing 14 together with a rotary cam 20 and are held stationary by two fastening bolts 24 designed to allow only these latches to rotate. The rota...

Abstract

A cylinder lock for use in a door lock, comprising an outer plug, an inner plug, a rotary cam adapted to move a deadbolt of the door lock, and a clutch adapted to engage for rotation the outer plug to the rotary cam. The cylinder lock further comprises an electronic blocking device (EBD) and a drive adapted to actuate the clutch upon an unblocking command from the EBD generated upon receiving therein an unblocking signal emitted from the outer side of the door, thereby enabling moving the deadbolt by rotation of the outer plug. The cylinder lock comprises an inner handle attached thereto at the inner side of the door, the EBD and the drive being entirely accommodated within the inner handle. The signal is emitted by an electronic key or panel and may be a mechanical vibration signal, a light signal, or a radio signal.

Description

technical field [0001] This invention relates to door cylinder locks (snag locks), and more particularly to electronic door locks that are opened by a coded input signal. Background technique [0002] Cylinder locks are well known and widely used as locking mechanisms in doors, windows, boxes, chests, safes, padlocks, bicycle locks, and the like. Mechanical cylinder locks have one or two cylindrical deadbolts (pin plugs) that can be turned by inserting a key to move the locking bolt from the door into the frame or back. Mechanical varieties of cylinder locks are standardized to enable mass production and general replacement and retrofitting of existing doors. Examples of conventional mechanical cylinder locks such as the European cylinder lock 1 , the Swiss lock 2 and the Schlage(R) locks 3 and 4 are shown in FIG. 1 . [0003] Electronic locks are also known. Some electronic locks have a keypad control panel near the door or on the door itself for entering an access code....
