An electric lock includes a base, a driving module, a handle and a clutch member. The driving module is arranged on the base. The driving module includes a driving member rotatable relative to the base, and a motor configured to drive the driving member to rotate. The handle is rotatably mounted to the base, and has a plurality of pushing structures. The clutch member includes a main body having a first end and a second end opposite to the first end, and a pushed structure formed on the first end of the main body.

Barricade devices and methods of barricading a door are disclosed. Such devices and methods may be used to barricade a door, and thereby prevent an intruder from entering a sheltering space, such as a classroom, storeroom, or hallway. The barricade-device may have a pivotable stop-device that is pivotable from a location adjacent to a door. The pivot-location may be at an elevation that is lower than a door handle on the door. The stop-device may be pivotable from a reserve-position to a stop-position. In the reserve-position, the stop-device does not barricade the door. In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the use of one or more major muscle groups of the body, but need not require precise dexterity of the fingers or hands (e.g. such as that required to manipulate small keys, latches, and/or the grasping and turning of assemblies). As such, the barricade-device may be used properly and quickly by a wide range of people having differing physical and mental capabilities.

An electromechanical locking device for a closure element includes a stator, with a rotor, a locking element and a blocking element, wherein the rotor is mounted in the stator, wherein the locking element is movable between two positions, wherein a starting position and a release position can be assumed by the blocking element. In the starting position, the blocking element prevents a movement of the locking element into the second position and in the release position the blocking element enables a movement of the locking element into the second position. The locking device includes a spring element, wherein the spring element interacts with the blocking element such that when the blocking element moves from the starting position into the release position, the spring element is at least temporarily tensioned in such a way that the spring element pushes the blocking element back in the direction of the starting position.
