Abstract
The presently disclosed subject matter is directed towards an anti-vandalism electronic cylinder lock (10). The lock comprising a cylinder housing (30), an electronic cylinder lock mechanism, an inside knob (26), and an outside knob (100), the outside knob (100) being configured for assuming a first non-accessible, non-operable, retracted position, and a second, accessible operative position, in which the outside knob (100) projects from the cylinder housing (30).
Claims10
An anti-vandalism electronic cylinder lock comprising a cylinder housing, an electronic cylinder lock mechanism, an inside knob, and an outside knob, the outside knob being configured for assuming a first non-accessible, non-operable, retracted position, and a second, accessible operative position, in which the outside knob projects from the cylinder housing.
A cylinder lock for use with a door lock configured for mounting in a door defining an inside and an outside, the lock comprising a housing accommodating an inside plug, an outside plug and a rotary cam for manipulating a deadbolt of the door lock, wherein, the inside plug is articulated to an inside knob fitted with a solenoid operable by an electric mechanism, and the outside plug is articulated with an outside knob, said outside knob displaceable between a closed position in which it is received within the cylinder housing and substantially flush with an outside surface of the cylinder housing, and an open position in which it projects from the outside surface of the cylinder housing and is engaged with the rotary cam.
A method of unlocking an anti-vandalism electronic cylinder lock, the method comprising:
- (a) Providing an electronic cylinder lock mechanism mounted within a cylinder housing fitted within a door lock, the electronic cylinder lock comprising an electronic cylinder lock mechanism, an inside knob, and an outside knob, the outside knob being configured for assuming a first non-accessible, non-operable, retracted position, and a second, accessible operative position, in which the outside knob projects from the cylinder housing;
- (b) Actuating the locking mechanism to unlock the cylinder lock;
- (c) Applying axial pressure on the knob, configured to achieve inward, axial displacement of the outside knob resulting in an outward axial displacement of the knob to at least partially project from the cylinder;
- and
- (d) Rotating the outwardly projecting knob to unlatch the lock.
A door fitted with a door lock comprising an electronic cylinder lock comprising a cylinder housing, an electronic cylinder lock mechanism, an inside knob, and an outside knob, wherein the outside knob is configured for assuming a first non-accessible, substantially non-operable, retracted position, and a second, accessible, operative position in which the outside knob is configured to project from the cylinder housing and is accessible from the outside.
