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.

A bolt restraint mechanism for restraining a bolt of a bolting mechanism, the bolt restraint mechanism comprising:
- a bolt moveable between thrown and retracted positions;
- a catch plate having an aperture through which the bolt extends, the catch plate biased to pivot such that a restraint surface of the aperture pushes against the bolt to restrain movement of the bolt;
- and
- a release trigger arranged such that when depressed the release trigger pushes against the catch plate to pivot releasing the restraint surface from pushing against the bolt to release the bolt.
A bolt restraint mechanism for restraining a bolt of a bolting mechanism moveable between thrown and retracted positions, comprising:
- a housing;
- a catch plate supported by the housing for pivotal movement and having a restraint surface at least partially defining an aperture through which the bolt extends, the restraint surface contacting the bolt in a pivoted position and restraining movement of the bolt;
- and
- a release supported by the housing such that when depressed the release contacts and pivots the catch plate from the pivoted position releasing the bolt.
