Abstract: A grenade device produces a delayed bang upon coupling to a pressurized canister containing gas. The device includes an annular housing, an awl, a sleeve, a diaphragm, a base and a cap. The housing has first and second axial ends and an internal bulkhead disposed therebetween with a choke flow-through orifice. The awl extends axially outward from the bulkhead. The sleeve connects to the housing at the first axial end. The diaphragm is disposed between the sleeve and the housing to form an annular chamber. The cap inserts into the housing at the second axial end and receives the canister facing the awl. The base connects to the housing at the second axial end. When the canister is compressed towards the device the awl punctures the canister to release the gas, which flows through the choke orifice to pressurize the chamber, and the diaphragm ruptures upon exceeding a pressure threshold.

Abstract: A device is provided for holding and releasing a missile within a canister. The device includes a housing attached to the canister, a latch mechanism extending from the housing into the canister, a tension applier disposed in the housing to restrain the missile in the canister, a release mechanism disposed on the housing, an interface mechanism and a compression applier. The tension applier forces the latch mechanism against the housing to withdraw from the missile. The interface mechanism initially couples the release mechanism and the tension applier. The compression applier anchors to the interface mechanism and forces the latch mechanism against the housing to engage the missile and counteract said tension applier. On command, the release mechanism disengages from the housing to release the compression applier from the interface mechanism. This action enables the tension applier to withdraw the latch mechanism from the missile.
