Abstract
Abstract A rotatable device for marine use is provided, comprising a housing designed to be embedded in the deck of the boat, with such housing having therein an opening in which is rotatably mounted a cleat member. The rotatable cleat member comprises a plate substantially flat on one side, and having affixed on its other side an upstanding cleat or other such fitting. The rotatable cleat member is supported by a pair of parallel shafts, with one extending outwardly from each side or end thereof, and each of the oppositely extending shafts being received in a respective elongate, vertical slot in the wall of the housing. At least one of the shafts is configured so as to be non-rotatable in a portion of its respective slot. A bias is provided for biasing the rotatable cleat member upwardly, with such bias being able to be overcome by finger pressure such that the cleat member can on occasion be moved downwardly in its housing. Such downward movement causes the shafts to be moved downwardly in their respective slots, which slots are enlarged at their bottom locations to permit the cleat member to then be rotated 180°, such that either the cleat or the flat plate may be selected to reside flush with the upper surface of the deck.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
179 words
A rotatable device for marine use, comprising a housing adapted to be embedded in the deck of the boat, said housing having an opening defined therein in which is mounted a rotatable member, said rotatable member comprising a plate substantially flat on one side, and having affixed on its other side an upstanding fixture, said member being rotatably supported by a pair of parallel, oppositely extending shafts, at least one of which shafts has flattened side edges that are closely received in an elongate, vertical slot in a wall of said housing, bias means normally biasing said member upwardly in its housing, said bias means being able to be overcome such that said member can be moved downwardly in its housing, this causing said oppositely extending shafts to be moved downwardly in their respective slots in said housing, said slots being enlarged at bottom locations to permit said member to be rotated 180° in either direction, such that either the fixture or the flat plate may be selected to reside in contact with the upper surface of the deck.
Claim 2
Dependent Claim
179 words
A rotatable device for marine use, comprising a housing adapted to be embedded in the deck of the boat, said housing having an opening defined therein in which is mounted a rotatable member, said rotatable member comprising a plate substantially flat on one side, and having affixed on its other side an upstanding fixture, said member being rotatably supported by a pair of parallel, oppositely extending shafts, at least one of which shafts has flattened side edges that are closely received in an elongate, vertical slot in a wall of said housing, bias means normally biasing said member upwardly in its housing, said bias means being able to be overcome such that said member can be moved downwardly in its housing, this causing said oppositely extending shafts to be moved downwardly in their respective slots in said housing, said slots being enlarged at bottom locations to permit said member to be rotated 180° in either direction, such that either the fixture or the flat plate may be selected to reside in contact with the upper surface of the deck.
Claim 3
Dependent Claim
18 words
The rotatable device as defined in claim 1 in which said member is rotatable about its longitudinal axis.
Claim 4
Dependent Claim
23 words
The rotatable device as defined in claim 2 in which manually releasable locking means are provided for preventing undesired rotation or other motion.
Claim 5
Dependent Claim
36 words
The rotatable device as defined in claim 1 in which both of said supporting shafts are non-circular at least one location, having flattened, parallel side edges that are closely received in respective slots in said housing.

Dependent Claim
18 words
The rotatable device as defined in claim 1 in which said member is rotatable about its lateral axis.
Claim 7
Dependent Claim
31 words
The rotatable device as defined in claim 5 in which one of its supporting shafts takes the form of a removable screw, the removal of which facilitates disassembly of the device.
Claim 8
Dependent Claim
15 words

Claim 9
Dependent Claim
184 words
A rotatable cleat for marine use comprising a housing adapted to be embedded in the deck of the boat, said housing having an opening defined therein in which is rotatably mounted a cleat member, said cleat member comprising a plate substantially flat on one side, and having affixed on its other side an upstanding cleat, said cleat member being rotatably supported by a pair of parallel, oppositely extending shafts, at least one of which shafts has flattened side edges that are closely received in an elongate, vertical slot in a wall of said housing, bias means normally biasing said cleat member upwardly in its housing, said bias means being able to be overcome such that said cleat member can be moved downwardly in its housing, this causing said oppositely extending shafts to be moved downwardly in their respective slots in said housing, said slots being enlarged at bottom locations to permit said cleat member to be rotated 180° in either direction, such that either the cleat or the flat plate may be selected to reside in contact with the upper surface of the deck.
Claim 10
Dependent Claim
184 words
A rotatable cleat for marine use comprising a housing adapted to be embedded in the deck of the boat, said housing having an opening defined therein in which is rotatably mounted a cleat member, said cleat member comprising a plate substantially flat on one side, and having affixed on its other side an upstanding cleat, said cleat member being rotatably supported by a pair of parallel, oppositely extending shafts, at least one of which shafts has flattened side edges that are closely received in an elongate, vertical slot in a wall of said housing, bias means normally biasing said cleat member upwardly in its housing, said bias means being able to be overcome such that said cleat member can be moved downwardly in its housing, this causing said oppositely extending shafts to be moved downwardly in their respective slots in said housing, said slots being enlarged at bottom locations to permit said cleat member to be rotated 180° in either direction, such that either the cleat or the flat plate may be selected to reside in contact with the upper surface of the deck.
