Abstract
A lock which includes a bolt which is movable between a locked position and an unlocked position against the action of a biassing element such as a spring, first retaining element which is engaged with the bolt and which retains the bolt in the locked position and which is movable between a first position at which the first retaining element restrains the bolt from being moved from the locked position to the unlocked position and a second position at which the first retaining element restrains the bolt from being moved from the unlocked position to the locked position, remotely actuable release element, which when actuated, causes movement of the first retaining element from the first position to the second position, and handle element for moving the bolt from the locked position to the unlocked position when the first retaining element is disengaged from the bolt.

22. A method of operating a lock that includes a bolt, a catch and a handle, the method comprising the steps of:
-
causing the bolt to move from a locked position to an unlocked position when the catch is moved by means of the handle from a latched position to an unlatched position;
storing energy when the bolt is moved from the locked position to the unlocked position;
latching the bolt at the unlocked position using a retainer;
with the bolt at the unlocked position allowing the handle to act on the catch independently of the bolt;
transmitting a signal to actuate the retainer to unlatch the bolt; and
allowing the bolt to move from the unlocked position to the locked position, under the action of the stored energy independently of the catch. - View Dependent Claims (23)
