Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 241 words
A new and improved inflatable life raft assembly comprising: inflatable life raft means; valve assembly means directly attached to said inflatable life raft means by a conduit without any other intervening support structure positioned between said valve assembly means and said raft, said valve assembly means includes a manually reciprocable valve member means for effecting inflation of said life raft means; said manually reciprocable valve member means including a non-shearable pin means positioned for manual removal within an aperture contained within a shaft of said valve member for manual removal to permit reciprocation of said valve member, said shaft formed with a manually engageable first end extending outwardly and exteriorly of a housing first end and extending interiorly of said housing terminating in a pointed second end proximate a compressed gas means securable to said housing at a housing second end remote from said housing first end, said non-shearable pin means positioned exteriorly of said housing, and said compressed gas means operably attachable to said valve assembly means for releasing gas to said inflatable raft means upon reciprocation of said valve member to rupture said compressed gas means; container means including a closure flap for enabling complete removal of said raft and valve member from said container means and for carrying said inflatable life raft means in a deflated condition, and attachment means for effecting a direct attachment to a user prior to an inflation of said inflatable life raft means.
Claim 2
Dependent Claim 241 words
A new and improved inflatable life raft assembly comprising: inflatable life raft means; valve assembly means directly attached to said inflatable life raft means by a conduit without any other intervening support structure positioned between said valve assembly means and said raft, said valve assembly means includes a manually reciprocable valve member means for effecting inflation of said life raft means; said manually reciprocable valve member means including a non-shearable pin means positioned for manual removal within an aperture contained within a shaft of said valve member for manual removal to permit reciprocation of said valve member, said shaft formed with a manually engageable first end extending outwardly and exteriorly of a housing first end and extending interiorly of said housing terminating in a pointed second end proximate a compressed gas means securable to said housing at a housing second end remote from said housing first end, said non-shearable pin means positioned exteriorly of said housing, and said compressed gas means operably attachable to said valve assembly means for releasing gas to said inflatable raft means upon reciprocation of said valve member to rupture said compressed gas means; container means including a closure flap for enabling complete removal of said raft and valve member from said container means and for carrying said inflatable life raft means in a deflated condition, and attachment means for effecting a direct attachment to a user prior to an inflation of said inflatable life raft means.
Claim 3
Dependent Claim 26 words
The new and improved portable inflatable life raft as described in claim 1, wherein said attachment means comprises flexible straps having hook and loop attachment means.
Claim 4
Dependent Claim 41 words
The new and improved portable inflatable life raft as described in claim 1, and further including guide means positioned within said valve assembly means, said guide means serving to direct said reciprocable valve member into contact with said compressed gas means.
Claim 5
Dependent Claim 39 words
The new and improved portable inflatable life raft as described in claim 3, and further including flange means attached to said reciprocable valve member, said flange means preventing said valve member from becoming disengaged from said valve assembly means.
Claim 6
Dependent Claim 34 words
The new and improved portable inflatable life raft as described in claim 4, and further including seal means for preventing gas from escaping to the atmosphere after a rupture of said compressed gas means.
Claim 7
Dependent Claim 34 words
The new and improved portable inflatable life raft as described in claim 5, and further including spring biasing means for maintaining said reciprocable valve member out of rupturing contact with said compressed gas means.
