Abstract
Abstract A parachute reefing/release device wherein when an actuator is activated and the device is subjected to a predetermined force, a multi-sectioned reefer will separate from a cylindrical housing causing separation of the multi-sectioned reefer into its components causing either a release of a submunition from a parachute or a reefing function of the parachute to take place.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A parachute reefing/release device comprising: a reefer having a plurality of severable sections; releasable means for holding said sections of said reefer together until such time as reefing/release action is desired, said releasable means having a safe position, an actuated position, and release of said reefer; force actuating means connected to said releasable means and said reefer for holding said releasable means in the safe position and allowing said releasable means to move to the actuated position upon the application of a predetermined force to said reefer; and means mounted adjacent said releasable means for initiating release of said releasable means when said releasable means is in the actuated position and a signal is supplied thereto.
Claim 2
Dependent Claim
116 words
A parachute reefing/release device comprising: a reefer having a plurality of severable sections; releasable means for holding said sections of said reefer together until such time as reefing/release action is desired, said releasable means having a safe position, an actuated position, and release of said reefer; force actuating means connected to said releasable means and said reefer for holding said releasable means in the safe position and allowing said releasable means to move to the actuated position upon the application of a predetermined force to said reefer; and means mounted adjacent said releasable means for initiating release of said releasable means when said releasable means is in the actuated position and a signal is supplied thereto.
Claim 3
Dependent Claim
104 words
A parachute reefing/release device comprising: a reefer having a plurality of severable sections; a cup shaped collar and stationary cylindrical housing mounted adjacent said reefer and holding said sections of said reefer in place; an axially upwardly movable shaft initially held stationary by a breakable shear wire positioned through said shaft and anchored in said cylindrical housing; an electro-explosive actuator fixed to said cylindrical housing; a slotted plate held stationary by a spring until said electro-explosive actuator is activated causing compression of said spring; and a shoulder extending radially outwardly from said shaft to engage said slotted plate prior to activation of said activator.
