Abstract
Abstract Apparatus is described for releasing a storage container from an inflatableupport such as a parachute, comprising a container for holding the inflatable support, an attachment mechanism extending through the container, linear slide means engaging the attachment mechanism and a storage container when tension is applied to the attachment mechanism, and means for holding the attachment mechanism in tension until the inflatable support is inflated, whereby the storage container remains fixed to the inflatable support until tension on said attachment component is relieved.

Claim 1
Independent Claim
215 words
A release mechanism for separating a storage container from a parachute comprising: a parachute container for holding a parachute; means for attaching a storage container to the bottom of said parachute container comprising: an attachment component having one end extending through a centrally located opening in the bottom of said parachute container for connecting to said parachute, said parachute providing a tension to said attachment component when deployed; linear slide means located on the bottom of said parachute container, said slide means having at least one horizontally movable end for engaging an opening in said storage container, said slide means being biased into engagement by a catch on the remaining end of said attachment component when tension is applied to said one end; means for maintaining tension on the one end of said attachment component until deployment of said parachute, said means for maintaining tension comprising a lever having one end pivoted to said attachment component, the remaining end of said lever being attached to the connecting lines of said parachute, said lever having a diameter less than said centrally located opening, and being pivoted into horizontal position with respect to said container bottom, whereby said storage container remains fixed to the bottom of said parachute container until tension is relieved from said attachment component.

215 words
A release mechanism for separating a storage container from a parachute comprising: a parachute container for holding a parachute; means for attaching a storage container to the bottom of said parachute container comprising: an attachment component having one end extending through a centrally located opening in the bottom of said parachute container for connecting to said parachute, said parachute providing a tension to said attachment component when deployed; linear slide means located on the bottom of said parachute container, said slide means having at least one horizontally movable end for engaging an opening in said storage container, said slide means being biased into engagement by a catch on the remaining end of said attachment component when tension is applied to said one end; means for maintaining tension on the one end of said attachment component until deployment of said parachute, said means for maintaining tension comprising a lever having one end pivoted to said attachment component, the remaining end of said lever being attached to the connecting lines of said parachute, said lever having a diameter less than said centrally located opening, and being pivoted into horizontal position with respect to said container bottom, whereby said storage container remains fixed to the bottom of said parachute container until tension is relieved from said attachment component.
Claim 3
Dependent Claim
215 words
A release mechanism for separating a storage container from a parachute comprising: a parachute container for holding a parachute; means for attaching a storage container to the bottom of said parachute container comprising: an attachment component havine one end extending through a centrally located opening in the bottom of said parachute container for connecting to said parachute, said parachute providing a tension to said attachment component when deployed; linear slide means located on the bottom of said parachute container, said slide means having at least one horizontally movable end for engaging an opening in said storage container, said slide means being biased into engagement by a catch on the remaining end of said attachment component when tension is applied to said one end; means for maintaining tension on the one end of said attachment component until deployment of said parachute, said means for maintaining tension comprising a retaining element located on the one end, and a flexible pin with two branches between said retaining element and said bottom, said pin branches being flexed so that they move away from retaining element in response to a force applied by said parachute to said attachment component, whereby said storage container remains fixed to the bottom of said parachute container until tension is relieved from said attachment component.
Claim 4
Dependent Claim
215 words
A release mechanism for separating a storage container from a parachute comprising: a parachute container for holding a parachute; means for attaching a storage container to the bottom of said parachute container comprising: an attachment component havine one end extending through a centrally located opening in the bottom of said parachute container for connecting to said parachute, said parachute providing a tension to said attachment component when deployed; linear slide means located on the bottom of said parachute container, said slide means having at least one horizontally movable end for engaging an opening in said storage container, said slide means being biased into engagement by a catch on the remaining end of said attachment component when tension is applied to said one end; means for maintaining tension on the one end of said attachment component until deployment of said parachute, said means for maintaining tension comprising a retaining element located on the one end, and a flexible pin with two branches between said retaining element and said bottom, said pin branches being flexed so that they move away from retaining element in response to a force applied by said parachute to said attachment component, whereby said storage container remains fixed to the bottom of said parachute container until tension is relieved from said attachment component.
Claim 5
Dependent Claim
29 words
The release mechanism of claim 1 or 2, further comprising means for preventing said linear slide means from engaging said opening once tension is released from said attachment component.
Claim 6
Dependent Claim
63 words
The release mechanism of claim 1 or 2, wherein the catch connected to the remaining end of said attachment component is shaped as a truncone, the broader part of said truncone providing a bearing surface for said linear slide means before release of said attachment component, the narrower portion providing a bearing surface to said slider means after the release of said attachment.
Claim 7
Dependent Claim
63 words
The release mechanism according to claim 4, wherein said slider means comprises two horizontal spring biased bolts, said bolts having an end for engaging one of two openings in said storage container, and a remaining end communicating with said truncone, wherein said larger diameter portion of the truncone maintains said bolts in said opening when a tension is applied to said attachment arm.
Claim 8
Dependent Claim
35 words
The release mechanism according to claim 1 or 2, further comprising at least one opening in the bottom of said parachute container for permitting movement of said slider means into engagement with the storage container.
