  • Publication number: 20010050323
    Abstract: An improved parachute and parachute deployment slider is disclosed. Embodiments of the improved slider seek to reduce slider rebound and more properly stage parachute deployment, particularly the deployment of ram air parachutes weighing two to fifteen pounds. One slider comprises of a rectangular fabric slider body with relatively lightweight grommets mounted adjacent each of the four corners on the slider. Another slider has relatively lightweight suspension line rings mounted externally from the slider fabric body at the corners of a rectangular slider body. One embodiment of the preferred parachute has a relatively smaller and lightweight pilot chute as well as relatively less elastic suspension lines at the slider stop positions on the parachute.

  • Patent number: 4428102
    Abstract: A quick release device comprising two members which may be releasably engaged to transmit a tensile force. Each of the members has a load-connection end and an engagement end. The engagement end of the members comprises two flat, elongate branches, with each of the branches terminating in a flat, rigid paddle. The paddles of one member foldingly engage the paddles of the second member whereby the paddles fold together into an interlocking arrangement. A releasable latch holds the paddles securely in the folded position so that the members can transmit a tensile force so long as the latch is in place, and the members will disengage from one another when the latch is released, without passing through any rings, links, loops or buckles.
