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).
Claims9
An electronic cylinder lock comprising a cylinder housing accommodating a two-stage pin assembly comprising a lower pin cooperating with an upper pin, a solenoid-operated electronic cylinder lock mechanism, an inside knob fitted with a solenoid therein, and an outside knob having a cavity, the outside knob being configured for assuming a first non-accessible, non-operable, retracted position, in which the outer knob is arrested from movement within the housing by projection of the two-stage pin assembly into the cavity;
- and a second, accessible operative position in which the outside knob is allowed to project from the cylinder housing following displacement of the two-stage pin assembly induced by the solenoid.
A method in accordance with 7, wherein applying inward axial pressure on the outside knob will urge the outside knob into its initial, retracted position.
