Abstract
Abstract A reefing device for parachutes is provided with means for confining a parachute, or a portion thereof, together with control means operable in response to a combination of factors, namely the amount and duration of the forces applied to the confining means, for effecting the release thereof. The reefing device is therefore operable under widely varying conditions of loading and speed of travel of the parachute.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A reefing device for a parachute comprising restraining means engaging the parachute to delay deployment of the parachute after release of the parachute from a carrier, a cylinder and piston assembly connected to said restraining means and including a cylinder and piston which are relatively movable in response to forces applied to the restraining means after release of the parachute, two relatively movable retaining members engageable to hold said restraining means in restraining position with respect to the parachute, one of said retaining members being connected to an element of said cylinder and piston assembly and movable thereby out of engagement with the other of said retaining members to release said restraining means and permit deployment of the parachute.
Claim 2
Dependent Claim
119 words
A reefing device for a parachute comprising restraining means engaging the parachute to delay deployment of the parachute after release of the parachute from a carrier, a cylinder and piston assembly connected to said restraining means and including a cylinder and piston which are relatively movable in response to forces applied to the restraining means after release of the parachute, two relatively movable retaining members engageable to hold said restraining means in restraining position with respect to the parachute, one of said retaining members being connected to an element of said cylinder and piston assembly and movable thereby out of engagement with the other of said retaining members to release said restraining means and permit deployment of the parachute.
Claim 3
Dependent Claim
21 words
A reefing device as defined in claim 1 wherein said restraining means encircles a portiOn of the canopy of the parachute.
Claim 4
Dependent Claim
23 words
A reefing device a defined in claim 1 wherein said restraining means has opposite end portions connected to said relatively movable retaining members.
Claim 5
Dependent Claim
63 words
A reefing device as defined in claim 1 wherein a mounting plate is carried by said restraining means, said cylinder and piston assembly are secured to said mounting plate, and one of said retaining members is movably mounted on said mounting plate and connected to said cylinder and piston assembly for movement thereby out of engagement with the other of said retaining members.
Claim 6
Dependent Claim
89 words
A reefing device for a parachute comprising means arranged to confine at least a portion of the parachute, control mechanism having spaced portions thereof connected to said confining means in position to be subjected to oppositely directed forces applied to said confining means, retaining members movable into and out of release position, and fluid displacing means connected to at least one of said spaced portions of the control mechanism and movable thereby to move said retaining members to said release position for releasing said confining means from said parachute.
Claim 7
Dependent Claim
89 words
A reefing device for a parachute comprising means arranged to confine at least a portion of the parachute, control mechanism having spaced portions thereof connected to said confining means in position to be subjected to oppositely directed forces applied to said confining means, retaining members movable into and out of release position, and fluid displacing means connected to at least one of said spaced portions of the control mechanism and movable thereby to move said retaining members to said release position for releasing said confining means from said parachute.
