Abstract
A bolt restraint mechanism for restraining a bolt of a bolting mechanism. The bolt restraint mechanism includes a bolt moveable between thrown and retracted positions and a catch plate having an aperture through which the bolt extends. The catch plate is biased to pivot such that a restraint surface of the aperture pushes against the bolt to restrain movement of the bolt. A release trigger is arranged such that when depressed the release trigger pushes against the catch plate to pivot thereby releasing the restraint surface from pushing against the bolt to release the bolt. The catch plate may be biased such that when the restraint surface pushes against the bolt to restrain movement of the bolt, the catch plate is non-orthogonal to the bolt.
Claims28
A touch bar assembly for releasing a bolt, the touch bar assembly comprising:
- a touch bar for actuation by a user;
- an action slider coupled to the touch bar, the action slider configured for lateral motion;
- a cam coupled to the action slider and arranged to couple the lateral motion of the action slider to a rotational motion for driving the bolt between an extended position and a retracted position;
- and
- a gating assembly arranged to block rotation of the cam and lateral motion of the of the action slider wherein (a) the gating assembly is arranged to be driven by an actuator to drive part of the gating assembly in to the path of the cam to block rotation of the cam and (b) the gating assembly comprises a blocking finger and a blocking rotor, the blocking finger is biased out of the path of the cam and the actuator is a motor configured to drive the blocking rotor to rotate the blocking finger into the path of the cam to block the cam.
