Abstract
Abstract A personnel or cargo net has a cushioned base spreader ring which carries a padded load supporting platform for the net, a top pick-up ring, an upper spreader ring of smaller diameter than the base spreader ring between the pick-up ring and base spreader ring, a web-like sidewall having longitudinally extending, circumferentially spaced lacings secured to the spreader rings and looped through the pick-up ring, a cable for securing the pick-up ring to a hoist, lacings secured at one end to the pickup ring and at the other end to the upper spreader ring and twisted along with the lacings which are looped through the pickup ring in a direction opposite to the lay of the cable whereby any rotative forces of the cable are resisted by the twisted lacings and spinning of the net is avoided.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
A personnel and cargo net comprising a base spreader ring carrying a platform to support the personnel or cargo, a second spreader ring spaced longitudinally from the base and of smaller cross-section than the base, a pick-up ring disposed above the second spreader ring, circumferentially spaced longitudinally extending lacings secured at each end to the base spreader ring, secured to said second spreader ring and looped through the pickup ring, lacings secured at one end to the second spreader ring and at the other end to the pick-up ring, said lacings being twisted and secured against untwisting adjacent to the pick-up ring, and a cable having a lay opposite to the direction of twisting of the lacings secured to the pick-up ring and adapted to be secured to a hoist.
Claim 2
Dependent Claim
130 words
A personnel and cargo net comprising a base spreader ring carrying a platform to support the personnel or cargo, a second spreader ring spaced longitudinally from the base and of smaller cross-section than the base, a pick-up ring disposed above the second spreader ring, circumferentially spaced longitudinally extending lacings secured at each end to the base spreader ring, secured to said second spreader ring and looped through the pickup ring, lacings secured at one end to the second spreader ring and at the other end to the pick-up ring, said lacings being twisted and secured against untwisting adjacent to the pick-up ring, and a cable having a lay opposite to the direction of twisting of the lacings secured to the pick-up ring and adapted to be secured to a hoist.
Claim 3
Dependent Claim
51 words
The net of claim 1 wherein said base spreader ring comprises top and bottom rings secured together in longitudinally spaced relationship, chordal strands form a web across the space enclosed by the top ring, a buoyant pad surrounds each spreader ring, and a cover is secured about the web and padding.
Claim 4
Dependent Claim
49 words
The net of claim 2 wherein longitudinally spaced cross-lacings extend only partially around the periphery of the space bordered by the longitudinally extending lacings, whereby at least one longitudinally extending opening is provided for access to the interior of the net between a pair of adjacent longitudinally extending lacings.
Claim 5
Dependent Claim
65 words
The net of claim 3 wherein 12 longitudinally extending lacings are spaced circumferentially about the base spreader ring and upper spreader ring, four lacings have one end secured to the upper spreader ring and the other end secured to the pick-up ring and said four lacings are twisted to the left and bound against untwisting by a rope wound thereabout adjacent to the pick-up ring.
Claim 6
Dependent Claim
69 words
The net of claim 1 wherein said cable is secured at one end to said pick-up ring and at the other end to means for attaching it to a hoist, and a plurality of elastic members of shorter length than the length of the cable are secured at one end to the pick-up ring and at the other end to the means for attaching the cable to the hoist.
Claim 7
Dependent Claim
21 words
The net of claim 5 wherein the weight of the platform exceeds the weight lifting capability of the said elastic members.
Claim 8
Dependent Claim
106 words
In a personnel or cargo net having a base and a pick-up means for attaching the net to a lifting means, said pick-up means and base being spaced longitudinally from each other, and lacings spaced circumferentially about the base, said lacings being secured to the base and looped through the pick-up means, the improvement which comprises providing a cable between said lifting means and pick-up means which has a lay in one direction and lacings which are twisted adjacent to the pick-up means in a direction which is opposite to the direction of the lay of the cable, and means for securing the lacings against untwisting.
Claim 9
Dependent Claim
106 words
In a personnel or cargo net having a base and a pick-up means for attaching the net to a lifting means, said pick-up means and base being spaced longitudinally from each other, and lacings spaced circumferentially about the base, said lacings being secured to the base and looped through the pick-up means, the improvement which comprises providing a cable between said lifting means and pick-up means which has a lay in one direction and lacings which are twisted adjacent to the pick-up means in a direction which is opposite to the direction of the lay of the cable, and means for securing the lacings against untwisting.
Claim 10
Dependent Claim
21 words
The combination of claim 7 wherein the cable has a right hand lay and the lacings are twisted to the left.
Claim 11
Dependent Claim
77 words
The net of claim 7 wherein the means for lifting the net comprises an inelastic cable and at least one elastic member secured to the top of the net and to means for attaching the said cable and member to a hoist, the length of the cable being greater than the relaxed length of the said member, and the weight of the said base spreader ring being greater than the weight lifting capability of the said member.
Claim 12
Dependent Claim
20 words
The net of claim 9 wherein at least one of the rings of the base spreader ring contains a ballast.
Claim 13
Dependent Claim
122 words
A personnel and cargo net comprising a base spreader ring carrying a platform to support the personnel or cargo, a second spreader ring spaced longitudinally from the base spreader ring, a pick-up ring disposed above the second spreader ring, circumferentially spaced longitudinally extending lacings secured to the base spreader ring and to said second spreader ring and looped through the pick-up ring, said base spreader ring comprising upper and lower rings secured together in longitudinally spaced relationship, a resilient means wrapped around the rings and the spaced therebetween to serve as a bumper for the rings and to impart buoyancy thereto, a web of chordal lacings across the space encircled by the upper of said rings, and a cover over the webbing.
Claim 14
Dependent Claim
122 words
A personnel and cargo net comprising a base spreader ring carrying a platform to support the personnel or cargo, a second spreader ring spaced longitudinally from the base spreader ring, a pick-up ring disposed above the second spreader ring, circumferentially spaced longitudinally extending lacings secured to the base spreader ring and to said second spreader ring and looped through the pick-up ring, said base spreader ring comprising upper and lower rings secured together in longitudinally spaced relationship, a resilient means wrapped around the rings and the spaced therebetween to serve as a bumper for the rings and to impart buoyancy thereto, a web of chordal lacings across the space encircled by the upper of said rings, and a cover over the webbing.
