Device for supporting a sub-frame of a disc record player on a frame, and disc record player comprising such a device

Claim 3

A device as claimed in claim 1, characterized in that each supporting element (10) comprises a tubular base (11), connected to the frame (2) and carrying a rigid projection (15) at its end which is remote from the frame, said projection being connected to the sub-frame (1) by means of the pivotal joint (20;25) near its end which is remote from the tubular base.

Claim 4

A device as claimed in claim 2, characterized in that the projection is a cylindrical spindle (15) whose axis (16) extends at least substantially parallel to the pivotal axis (5) of the scanning arm (4) and intersects the pivotal axis (21) of the pivotal joint (20; 25) at least substantially perpendicularly.

Claim 5

A device as claimed in claim 3, characterized in that the pivotal axis (21) of the pivotal joint (20; 25) is situated near that side of a mounting plate (1A) of the sub-frame (1) which faces the frame.

Claim 6

A device as claimed in claim 4, characterized in that the supporting element (10) further comprises a helical spring (17) which surrounds the tubular base (11) and which at the side of the sub-frame (1) acts against a spring seat (18; 24), which retains the helical spring (17) at a level which relative to the pivotal axis (21) is situated at the side opposite the side at which the mounting plate (1A) is situated.

Claim 7

A device as claimed in claim 5, characterized in that the pivotal joint comprises a trunnion (20) which is connected to the spindle (15) and which at least over a part of its length is retained between the mounting plate (1A) and the spring seat (18) secured to said plate.

Claim 8

A device as claimed in claim 5, characterized in that the spring seat (24) is mounted on the spindle (15) and is connected to the mounting plate (1A) by the trunnion (25).

Claim 9

A disc-record player, comprising a frame (2) and a sub-frame (1), which carries a turn-table (3) and a scanning arm (4) which is pivotable about a pivotal axis (5), which player is provided with a device (9) for supporting the sub-frame on the frame, said device comprising a plurality of supporting elements (10) arranged between the frame and the sub-frame for damping vibrations or shocks exerted on the sub-frame via the frame, the sub-frame carrying parts, including a turn-table (3) and a scanning arm (4) with a scanning element (6), which arm is pivotable about a pivotal axis (5), characterized in that the supporting elements (10) are connected to the sub-frame by means of pivotal joints (20; 25), the pivotal axis (21) of said joints (20; 25) being oriented radially or substantially radially of the mass centre (M) of the sub-frame (1) including the parts carried by said sub-frame.

Claim 10

A disc-record player, comprising a frame (2) and a sub-frame (1), which carries a turn-table (3) and a scanning arm (4) which is pivotable about a pivotal axis (5), which player is provided with a device (9) for supporting the sub-frame on the frame, said device comprising a plurality of supporting elements (10) arranged between the frame and the sub-frame for damping vibrations or shocks exerted on the sub-frame via the frame, the sub-frame carrying parts, including a turn-table (3) and a scanning arm (4) with a scanning element (6), which arm is pivotable about a pivotal axis (5), characterized in that the supporting elements (10) are connected to the sub-frame by means of pivotal joints (20; 25), the pivotal axis (21) of said joints (20; 25) being oriented radially or substantially radially of the mass centre (M) of the sub-frame (1) including the parts carried by said sub-frame.
