Abstract

A mount for a record player with variable antivibration controls that make it possible for the user of the player to separately establish an optimum antivibration setting depending on the conditions of the specific surface that the player is resting on and on the overall acoustical conditions with respect to footstep and acoustical feedback.

Claims

1. A resilient chassis mount and/or housing mount with variable antivibration controls for a record player, wherein resilient materials, like rubber and like helical springs in particular, produce separation in conjunction, comprising the following means positioned mutually coaxial:

helical spring means;

rubber antivibration means comprising a flange, and segments in shape of a cylindrical surface and in one piece therewith;

setting means in shape of a cylindrical surface and having segments with walls varying in thickness along one direction of rotation, said setting means having a radially projecting arm for initiating rotation; and

flange means with a concentric means for accommodating said setting means.

2. A resilient chassis mount and/or housing mount as defined in claim 1, wherein said helical spring means is at least partly cylindrical.

3. A resilient chassis mount and/or housing mount as defined in claim 1, wherein said segments of said rubber antivibration means are positioned between said helical spring means and said cylindrical surface of said setting means.

4. A resilient chassis mount and/or housing mount as defined in claim 2, wherein said helical spring means is on the inside and said setting means is on the outside.

5. A resilient chassis mount and/or housing mount as defined in claim 2, wherein said helical spring means is on the outside and said setting means is on the inside.

6. A resilient chassis mount and/or housing mount as defined in claim 1, wherein said helical spring means comprises a compression spring.

7. A resilient chassis mount and/or housing mount as defined in claim 1, wherein each section of said setting means has a wall varying in thickness over 120°

.

8. A resilient chassis mount and/or housing mount as defined in claim 1, wherein each section of said rubber anti-vibration means assumes an angle of 60°

.

9. A resilient chassis mount and/or housing mount as defined in claim 1, wherein said concentric means comprises a shoulder.

10. A resilient chassis mount and/or housing mount as defined in claim 1, wherein said concentric means comprises a setback.

11. A resilient chassis mount and/or housing mount as defined in claim 1, whrein said concentric means comprises a groove.
