Diver operated retractable pad eye

Claim 2

A retractable pad-eye device in combination with a plate forming part of a hull or housing and having inner and outer surfaces and an opening therethrough, said device comprising: pivot-block means; trunnion means supporting said pivot-block means for rotation about an axis parallel to and spaced from said inner surface; a closure member; a pad-eye member having a bail; first and second means operatively connecting said closure member and said pad-eye member to said pivot-block means for rotation therewith about said axis to selectively bring said closure member and said pad-eye member alternatively into registration with said opening; said first means being operable, when said closure member is in registration with said opening, to move said closure member into and out of engagement with said plate and closing relation to said opening; and said second means being operable, when said pad-eye member is in registration with said opening, to move said pad-eye member into and out of engagement with said plate and closing relation to said opening with said bail exposed for attachment.

Claim 3

A device as defined in claim 1, and wherein: said first and second means comprise first and second jack-screws.

Claim 4

A device as defined in claim 2, and wherein: said pivot-block means comprises first and second pivot-block halves and means for securing said halves together.

Claim 5

A device as defined in claim 2, and wherein: p1 said trunnion means comprises a trunnion shaft extending from opposite sides of said pivot-block means, and trunnion bearing means fixed to said plate and having said trunnion shafts journalled therein.

Claim 6

A device as defined in claim 2, and wherein: said closure member comprises an obturator portion and a flange portion, said obturator portion having a complementary configuration engageable in said opening with said flange portion bearing against said inner surface of said plate, and said obturator portion presenting a substantially flush surface with said outer surface of said plate.

Claim 7

A device as defined in claim 2, and wherein: said pad-eye member comprises an obturator portion and a flange portion, said obturator portion having a complementary configuration engageable in said opening with said flange portion bearing against said inner surface of said plate, said obturator portion presenting a substantially flush surface with said outer surface of said plate, and said bail projecting outwardly of said flush surface and said outer surface.

Claim 8

A device as defined in claim 2, and further comprising: guide means cooperating between said closure member and said pivot-block means and between said pad-eye member and said pivot-block means, said guide means being operative to constrain said closure member and said pad-eye member to translational movements relative to said pivot-block means.

Claim 9

A device as defined in claim 7, and wherein: said guide means comprises cooperating rods and guide bores, said rods having sliding fits in corresponding guide bores.

Claim 10

A retractable pad-eye device in combination with a structure including a plate-like wall having inner and outer sufaces and an opening therethrough of predetermined configuration, said device comprising: a closure member having an operative position in said opening and a storage position remote from said opening; a pad-eye member having an operative position in said opening and a storage position remote from said opening; a pivot member; means supporting said pivot member in spaced relation to said wall for rotation about a predetermined axis. first and second connecting means supporting said closure member and said pad-eye member on said pivot member whereby rotation thereof about said axis between first and second rotative positions will alternatively move said closure member and said pad-eye member from their respective storage positions to intermediate positions in registration with said opening; said first connecting means being operative to move said closure member between said operative and said intermediate positions thereof when said pivot member is in one of said rotative positions; said second connecting means being operative to move said pad-eye menber between said operative and intermediate positions thereof when said pivot member is in the other of said rotative positions.

Claim 11

A retractable pad-eye device in combination with a structure including a plate-like wall having inner and outer sufaces and an opening therethrough of predetermined configuration, said device comprising: a closure member having an operative position in said opening and a storage position remote from said opening; a pad-eye member having an operative position in said opening and a storage position remote from said opening; a pivot member; means supporting said pivot member in spaced relation to said wall for rotation about a predetermined axis. first and second connecting means supporting said closure member and said pad-eye member on said pivot member whereby rotation thereof about said axis between first and second rotative positions will alternatively move said closure member and said pad-eye member from their respective storage positions to intermediate positions in registration with said opening; said first connecting means being operative to move said closure member between said operative and said intermediate positions thereof when said pivot member is in one of said rotative positions; said second connecting means being operative to move said pad-eye menber between said operative and intermediate positions thereof when said pivot member is in the other of said rotative positions.

Claim 12

A device as defined in claim 9, and wherein: said means supporting said pivot member comprises a trunnion shaft and trunnion bearing means.

Claim 13

A device as defined in claim 10, and wherein: said first and second connecting means comprise first and second jackscrews.

Claim 14

A device as defined in claim 11, and wherein: said first and second connecting means further comprise guide bore and rod means for constraining said closure member and said pad-eye member against rotation relative to said pivot member.

Claim 15

A device as defined in claim 12, and wherein: said closure member and said pad-eye member each comprise an obturator portion and a flange portion adapted respectively to fill said opening and to bear against said inner surface of said wall.

Claim 16

A device as defined in claim 13, and wherein: said pad-eye member further comprises a bail defining an eye, said bail spanning said obturator portion.

Claim 17

A device as defined in claim 14, and wherein: said first and second jack-screws are threadedly engaged in said closure member and said pad-eye member, respectively, each of said screws being rotatably connected to said pivot member.
