LOCK ASSEMBLY
A lock assembly (1) comprising one or two drop lock plunger(s) (2) configured to be in a locked operation state and in an unlocked operation state, a locking member (3) arranged to be moveable between an outer and an inner position, a pressure body (4) mounted to linearly cooperate with said locking member (3), a holding arm having an elongated shape and arranged to be rotatable about a rotation axis at one of its ends, and- an electromagnetic member (14) that upon activation is arranged to apply a pulling force to a release arm (7). The lock assembly further comprises an amplifier arm (6) having an elongated shape and arranged to be rotatable about a rotation axis at one of its ends, the other end is structured to cooperate with said release arm (7). The amplifier arm is provided with two contact surfaces, a first contact surface (20) in an indentation (16) intended to be in contact with the contact surface at other end of said holding arm (5), and a second contact surface (19) intended to be in contact with a contact surface of said pressure body protrusion (15), and wherein, when in the locked state and external pressure is supplied to the drop lock plunger (1), the external pressure is resulting in that a rotational force is applied to said amplifier arm (6) in a first direction. Upon activation of said electromagnetic member (14), the rotational force provides movement to the amplifier arm (6) such that the first contact surface (19) is released from the holding arm, thereby allowing the locking member (3) to move inwards that in turn will transfer the drop lock plunger into their unlocked operation state.
