Abstract
Abstract A device for coupling together two bodies having relative motion therebetween, such as a submarine deck and hull, which comprises a bearing member having a generally flat surface on one of its sides, an arm member adapted to be pivotally connected to one of the bodies, a slide member adopted to be fixedly connected to the other of the bodies and having a slot therein adopted to receive the flat surface of the bearing member in slideable relationship therewith, and a concavo-convex connection between the bearing member and the arm member permitting relative movement therebetween. In one embodiment of the invention the device includes a second bearing member adapted to be received in slideable relationship in a second slot in the slide member and a second concavo-convex connection between the second bearing member and the arm member, wherein the concavo-convex connections are hemispherical in shape and the bearing members are constructed of a plastic material having a low coefficient of friction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
In a submarine having a hull and at least one internal, generally horizontal deck supported by said hull, the improvement which comprises coupling sAid deck to said hull with a plurality of coupling devices, each of said coupling devices comprising a bearing member having a bottom bearing surface generally hemispherical in shape and a top bearing surface which is generally flat, a generally horizontal arm member one end thereof being pivotally connected to said hull and the other end thereof having a generally hemispherically shaped socket in the top side thereof, said socket being adapted to receive the hemispherically-shaped surface of said bearing member in rotational relationship therewith, and a slide member having one end there fixedly connected to said deck and including a generally horizontal slot in the upper part thereof adapted to receive the flat surface of said bearing member in slideable relationship therewith.
Claim 2
Dependent Claim
146 words
In a submarine having a hull and at least one internal, generally horizontal deck supported by said hull, the improvement which comprises coupling sAid deck to said hull with a plurality of coupling devices, each of said coupling devices comprising a bearing member having a bottom bearing surface generally hemispherical in shape and a top bearing surface which is generally flat, a generally horizontal arm member one end thereof being pivotally connected to said hull and the other end thereof having a generally hemispherically shaped socket in the top side thereof, said socket being adapted to receive the hemispherically-shaped surface of said bearing member in rotational relationship therewith, and a slide member having one end there fixedly connected to said deck and including a generally horizontal slot in the upper part thereof adapted to receive the flat surface of said bearing member in slideable relationship therewith.
Claim 3
Dependent Claim
106 words
The invention according to claim 1 including a second bearing member having a first bearing surface generally hemispherical in shape on one of its sides and a second generally flat bearing surface on its opposite side, said arm member including a second generally hemispherically-shaped socket in the side thereof opposite said first-mentioned hemispherically shaped socket, said second socket being adapted to receive the hemispherically-shaped surface of said second bearing member in rotational relationship therewith, and said slide member including a second slot in parallel spaced relationship to said first-mentioned slot and adapted to receive the flat surface of said second bearing member in slideable relationship therewith.
Claim 4
Dependent Claim
49 words
The invention according to claim 2 wherein said slide member includes a spacer member mounted in one of said slots and adapted to bear against the flat bearing surface of the associated bearing member to thereby urge the hemispherical surface thereof into the associated socket of said arm member.
Claim 5
Dependent Claim
68 words
The invention according to claim 1 wherein the end of said arm member connected to said hull is clevis-shaped and is provided with a pair of aligned bore holes in the clevis-shaped portion thereof, said coupling device including a vertically disposed pin pivotally mounted in the bore holes of said clevis-shaped portion of said arm member and a support element connected to said hull pivotally engaging said pin.
Claim 6
Dependent Claim
22 words
The invention according to claim 1 wherein said bearing member is made of a plastic material having a low coefficient of friction.
Claim 7
Dependent Claim
14 words
The invention according to claim 5 wherein said plastic is an acetal fluorocarbon resin.
Claim 8
Dependent Claim
35 words
The invention according to claim 1 wherein said slide member includes a rectangular-shaped housing and the end thereof adjacent said hull is provided with a flexible sealing element between said housing and said arm member.
Claim 9
Dependent Claim
153 words
In combination with two bodies having relative motion therebetween and in which one of said bodies supports the other of said bodies wherein said one body is a submarine and said other body is an internal submarine deck, a coupling device which comprises a bearing member having a bottom bearing surface generally hemispherical in shape and a top bearing surface which is generally flat, a generally horizontal arm member one end thereof being pivotally connected to one of said bodies and the other end thereof having a generally hemispherically-shaped socket in the top side thereof, said socket being adapted to receive the hemispherically-shaped surface of said bearing member in rotational relationship therewith, and a slide member having one end thereof fixedly connected to the other of said bodies and including a generally horizontal slot in the upper portion thereof adapted to receive the flat surface of said bearing member in slideable relationship therewith.
Claim 10
Dependent Claim
153 words
In combination with two bodies having relative motion therebetween and in which one of said bodies supports the other of said bodies wherein said one body is a submarine and said other body is an internal submarine deck, a coupling device which comprises a bearing member having a bottom bearing surface generally hemispherical in shape and a top bearing surface which is generally flat, a generally horizontal arm member one end thereof being pivotally connected to one of said bodies and the other end thereof having a generally hemispherically-shaped socket in the top side thereof, said socket being adapted to receive the hemispherically-shaped surface of said bearing member in rotational relationship therewith, and a slide member having one end thereof fixedly connected to the other of said bodies and including a generally horizontal slot in the upper portion thereof adapted to receive the flat surface of said bearing member in slideable relationship therewith.
