Orientable pivot in particular for a television set

Claim 2

An orientable pivot in particular for a television set, comprising a case, a support plate parallel to and spaced from said case, mounting means comprising two series of rolling elements disposed on each side of said support plate adjacent to an outer peripheral edge of said support plate between said support plate and said case for rotatively mounting said support plate relative to said case, said case support plate and said series of rolling elements being coaxial, and combined resiliently yieldable means for taking up axial play between said case and said support plate and for braking said support plate relative to the case, said resiliently yieldable means being in an axially stressed condition between said case and said support plate and in rubbing contact with said support plate.

Claim 3

An orientable pivot in particular for a television set, said pivot comprising a case, a support plate parallel to and spaced from said case, mounting means comprising two series of rolling elements disposed on each side of said support plate adjacent to an outer peripheral edge of said support plate, a first raceway and a second raceway, a first series of said series of rolling elements being disposed between a first surface of said support plate and said first raceway and a second series of said series of rolling elements being disposed between a second surface of said support plate opposed to said first surface and said second raceway, said support plate, said case and said raceways being coaxial, a flexible member for taking up play being disposed between said case and one of said first and second raceways, and braking means for braking said support plate relative to said case and comprising a substantially axially extending lip of said flexible member, which lip is in sliding contact with a surface of said support plate.

Claim 4

An orientable pivot in particular for a television set, said pivot comprising a case, a support plate parallel to and spaced from said case, mounting means comprising two series of rolling elements disposed on each side of said support plate adjacent to an outer peripheral edge of said support plate, a first raceway and a second raceway, a first series of said series of rolling elements being disposed between a first surface of said support plate and said first raceway and a second series of said series of rolling elements being disposed between a second surface of said support plate opposed to said first surface and said second raceway, said support plate, said case and said raceways being coaxial, a flexible member for taking up play being disposed between said case and one of said first and second raceways, and braking means for braking said support plate relative to said case and comprising a substantially axially extending lip of said flexible member, which lip is in sliding contact with a surface of said support plate.

Claim 5

An orientable pivot according to claim 2, wherein said flexible member is of plastics material and said lip terminates in a shoe which is in rubbing relation to the surface of said support plate.

Claim 6

An orientable pivot according to claim 3, wherein said flexible member is of spring steel and said lip terminates in a flange, a ring of a material having an appropriate coefficient of friction being interposed between said flange and the surface of the support plate.

Claim 7

An orientable pivot according to claim 3, wherein said flexible member is of spring bronze and said lip terminates in a flange, a ring of a material having an appropriate coefficient of friction being interposed between said flange and the surface of the support plate.

Claim 8

An orientable pivot according to claim 1, wherein said case includes a base member and a hollow round cover, said support plate being round and having a diameter which is such that said support plate extends with minimum clearance into said cover, said support plate having an edge surface which cooperates with a confronting surface of said cover so as to form a radial bearing.

Claim 9

An orientable pivot according to claim 1, wherein said combined resiliently yieldable means for taking up axial play and braking said support plate has a continuous annular portion which is disposed radially inwardly of the series of rolling elements on an upper side of said support plate and provides a seal between said upper side of said support plate and said case and a protection of said series of rolling elements.
