Abstract
An apparatus and an article of manufacture providing a parachute ripcord pull force reducer device, method and system offering mechanical gain such that the pull force required to pull the main parachute closing pin is reduced. Further disclosed is a parachute container using the novel parachute ripcord pull force reducer, and methods for manufacturing and/or modifying a parachute to operate with various embodiments of the ripcord pull force reducer in accordance with the instant disclosure.
Claims5
A parachute compound pulley ripcord pull force reducer comprising:
- A first line section having a first end fixedly coupled to a movable ring member and a second end fixedly attached to an anchor point, the first line section slidingly engages a pin having an eyelet forming a pin engagement point, the first line section forming a first tension section;
- An activation line fixedly coupled to the anchor point and extending therefrom to slidingly engage the movable ring member, a portion of the activation line between the anchor point and the movable ring member forming a second tension section, the activation line further extending away from the movable ring member to form a third tension section coupled to a pull handle, the activation line being arranged such that a tensile force applied to the pull handle is transmitted to the pin via the first, second, and third tension sections, the second and third tension sections forming a dynamically determined angle therebetween during application of the tensile force to the handle.
A parachute compound pulley ripcord pull force reducer comprising:
- an activation line having a first end fixedly coupled to a movable ring member, the activation line extending therefrom and slidingly engaging a pin at a pin engagement point, a portion of the activation line forming a first tension section extending generally between the movable ring member and an anchor ring, the activation line slidingly engaging the anchor ring and further extending from the anchor ring to slidingly engage the movable ring member, a portion of the activation line forming a second tension section between the anchor ring and the movable ring, and further extending away from the movable ring member to form a third tension section coupled to a pull handle, the activation line being arranged such that a tensile force applied to the pull handle is transmitted to the pin via the first, second, and third tension sections.
A parachute container comprising:
- a. A compartment comprising a backing and at least one flap having a closing hole;
- b. a closing loop coupled to the container, the closing loop positioned to interact with the closing hole to maintain the flap is a closed state by a pin passed in the closing loop, the pin having a pin engagement point;
- c. an anchor point coupled to the container;
- d. an activation line having a ring member coupled to an end thereof, the activation line extending from the ring member and slidingly engaging the pin at an engagement point, a first segment of the activation line forming a first tension section extending generally between the ring member and the anchor point, the activation line further extending from the anchor point to the ring member and slidingly engaging the ring member, a portion of the activation line forming a second tension section between the anchor point and the ring member, and further extending away from the ring member to form a third tension section coupled to a pull handle;
- the second and third tension sections are formed by a second segment of the activation line and are being arranged such that when tensile force is applied to the activation line from the pull handle, the second and third tension sections form a dynamically determined pulley angle therebetween, the pulley angle apex being at the ring member, and the second and third tension section imparting a tensile force on the ring member.
