Quick release supporting apparatus for a canister

The quick release canister supporting apparatus of the present invention includes a mounting bracket mountable to a rigid support, a rigid, canister retaining frame releasably mountable into mating engagement with the mounting bracket, and at least one latch cooperating between the mounting bracket and the retaining frame for the releasable mounting into mating engagement of the retaining frame with the mounting bracket. The latch may be mounted to the mounting bracket or to the retaining frame. A manually operable release actuator cooperates with the latch for selective actuation of the latch to release the retaining frame from the mounting bracket. The retaining frame defines a rigid cavity having an opening for receiving a gas canister substantially completely into the cavity. The retaining frame includes at least one selectively releasable canister rotation restraint for inhibiting rotation and sliding of the canister about and along its longitudinal axis. At least one selectively releasable canister ejection restraint may also be provided for inhibiting sliding ejection of the canister from the cavity.
