Abstract

Abstract In the legs of a clevis of a webbing connector are opposite aligned passages in which is journalled a pin for harness webbing. The pin is formed of a release body the hub of which fits between the legs. Parts of a pair of lock pins project the hub into the respective passages to hold the pin in place. The lock pins are fixed in the body by shear pins. Inside of the hub are a pair of plungers. A slot in each plunger riding on a set screw limits the outward movement of each plunger respectively to the adjacent end of the hub, whereby the adjacent lock pin is pushed totally into the leg passage and the release body is freed. The force for outward movement of the plungers is imparted through a thruster which includes a suitable expandable device which when expanded axially pushes the plungers apart for pushing the lock pins out of the hub of the release body.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 131 words
In a harness release pin a connector element having spaced legs and axially registering passages in said legs, a release body engageable by a harness webbing, a hub of the release body fitting between the legs and having a passage therethrough in axial registry with the passages in said legs, a lock pin in each end of the passage of said hub extending into the passage of the adjacent leg to hold said hub in connecting position, expandable means between said lock pins for pushing said lock pins apart and out of said hub passage, and controlled means to impart a force to such expandable means to expand in opposite directions to push said lock pins out of said hub passage into the respective leg passages for releasing said release body.
Claim 2
Dependent Claim 131 words
In a harness release pin a connector element having spaced legs and axially registering passages in said legs, a release body engageable by a harness webbing, a hub of the release body fitting between the legs and having a passage therethrough in axial registry with the passages in said legs, a lock pin in each end of the passage of said hub extending into the passage of the adjacent leg to hold said hub in connecting position, expandable means between said lock pins for pushing said lock pins apart and out of said hub passage, and controlled means to impart a force to such expandable means to expand in opposite directions to push said lock pins out of said hub passage into the respective leg passages for releasing said release body.
Claim 3
Dependent Claim 55 words
The harness release pin specified in claim 1, and said expandable means including a pair of plungers engageable with the respective lock pins, limiting means in said hub to limit the outward movement of said plungers to where the outer ends of said plungers are in registry with the respective outer ends of said hub.
Claim 4
Dependent Claim 68 words
The harness release pin specified in claim 2, and said limiting means being a slot in each plunger, and a projecting element extended from said body into each slot, the inner end of each slot being at a distance from the said projecting element equal to the distance between the outer end of the plunger and the adjacent outer end of the hub in the initial connecting position.
Claim 5
Dependent Claim 33 words
The harness release pin specified in claim 1, and a shear member holding each lock pin in said passage of said hub and being sheared by the force exerted by said expandable means.
