Abstract:
1. An electromechanical lock comprising: a housing; a locking lever slidably received by the housing; a blocking element positioned adjacent the locking lever, the blocking element rotatably movable between a first blocking element position that engages the locking lever and a second blocking element position that disengages the locking lever, the blocking element including a first non-threaded internal chamber, a second non-threaded internal chamber and a threaded internal annular ring positioned therebetween, said threaded internal annular ring having an axial length; a rotatable shaft received through said blocking element, said rotatable shaft having a first non-threaded portion and a second non-threaded portion with an annular threaded portion positioned therebetween, said annular threaded portion having an axial length substantially equal to the axial length of the threaded internal annular ring; a first spring co-axially surrounding said first non-threaded portion of the shaft and a second spring coaxially surrounding said second non-threaded portion of the shaft, said first and second springs structured to bias the blocking element toward the annular threaded portion of the shaft in the respective first and second blocking element positions; and an actuating device operable to control movement of the blocking element between the first and second positions.
