Abstract

An isolator comprising a base (2) and a shell (3) connected to but extending from the base (2). The shell (3) has an aperture (15) substantially opposite the base (2). A support structure such as a connecting arm (27) is provided having one end positioned within the shell (3). The connecting arm (27) has means thereon exterior to the shell whereby the connecting arm (27) may be connectable in use to a structure. Also provided are a plurality of links (45), each link (45) being pivotally connected at or adjacent one end to the shell (3) and being pivotally connected at or adjacent the other end to the connecting arm (27). The connection between each link (45) and the connecting arm (27) is closer to the base (2) than the connection between each link (45) and the shell (3), the link (45) comprising an arm (46) having two apertures (47).

Description

Vibration Isolator and Connecting Rod Summary An isolator includes a base (2) and a housing (3) connected to but extending from the base (2). The housing (3) has a hole (15) substantially opposite to the base (2). A support structure such as a connecting arm (27) is provided, one end of which is located inside the housing (3). The connecting arm (27) has means located outside the housing, so that the connecting arm (27) can be connected to the structure in use. A plurality of links (45) are also provided, each link (45) being pivotally connected at one end or adjacent to the housing (3) and at the other end or adjacent to the connecting arm (27). The connection point between each link (45) and the connecting arm (27) is closer to the base (2) than the connection point between each link (45) and the housing (3), and the link (45) includes an arm (46) having two holes (47).

Claims

CLAIMS:

1. A link (45) characterised in that the link (45) has an arm (46) having a first recess or aperture (47) and a second recess or aperture (47) spaced from the first recess or aperture (47), the first recess or aperture (47) receiving a first bearing (48) and the second recess or aperture (47) receiving a second bearing (48), the first bearing (48) being attachable in use to a first structure and the second bearing being attachable in use to a second structure so as to allow movement of one structure substantially independently of the other structure over at least some distance, the recess or aperture (47) having an inward facing surface (49) and the bearing (48) having an outward facing surface, the inward facing surface (49) of the recess or aperture (47) and the outward facing surface of the bearing (48) being substantially arcuate.

2. A link as claimed in claim 1 characterised in that the radius of curvature of each arcuate surface is substantially identical.

3. An isolator comprising a base (2), and a shell (3) connected to but extending from the base (2), characterised in that the shell (2) has an aperture (15) substantially opposite the base (2), a support structure having at least a part thereof positioned within the shell (3), and a plurality of links (45), each link (45) being pivotally connected at or adjacent one end to the shell (3) and being pivotally connected at or adjacent the other end to the support structure, the connection between each link (45) and the support structure being closer to the base (2) than the connection between each link (45) and the shell (3).

4. An isolator as claimed in claim 3 characterised in that the support structure includes a connecting arm (27) having one end positioned within the shell, the connecting arm (27) having means thereon exterior to the shell (3) whereby the connecting arm (27) may be connectable to a structure.

5. An isolator as claimed in claim 3 characterised in that the support structure includes a disc (116) on which a structure rests in use.

6. An isolator as claimed in any one of claims 3 to 5 characterised in that each link (45) comprises an arm (46) having a first recess or aperture (47) and a second recess or aperture (47) spaced from the first recess or aperture (47), the first recess or aperture (47) receiving a first bearing (48) and the second recess or aperture (47) receiving a second bearing (48), the first bearing (48) being attachable in use to the shell (3) and the second bearing being attachable in use to the connecting arm (27) so as to allow movement of the shell (3) and connection arm (27) substantially independently of the other structure over at least some distance, each recess or aperture (47) having an inward facing surface (49) and each bearing (48) having an outward facing surface, the inward facing surface (49) of the recess or aperture (47) and the outward facing surface of the bearing (48) being substantially arcuate.

7. An isolator as claimed in claim 6 characterised in that the radius of curvature of each arc is substantially identical.

8. An isolator as claimed in any one of claims 3 to 7 characterised in that the connection between each link (45) and the shell (3) is adjacent the aperture (15) in the shell (3).

9. An isolator as claimed in claim 4 characterised in that each connection between the link (45) and the shell (3) and between each link (45) and the connecting arm (27) allows pivotal movement in the plane of the link (45) and rotational movement about the axis of the link (45).

10. An isolator as claimed in any one of claims 3 to 9 characterised in that three links (45) are provided spaced substantially equidistantly about the shell (3).

11. An isolator as claimed in any one of claims 3 to 10 characterised in that the base (2) is connected to the shell (3) in a manner which allows adjustment between the base (2) and the shell (3) to allow the distance between the base (2) and the connecting arm (27) to be varied.

12. An isolator as claimed in any one of claims 3 to 9 characterised in that the connecting arm (27) extends outwardly through the aperture (15) in the shell (3).

13. An isolator as claimed in claim 9 characterised in that movement between the shell (3) and the support for a sound producing device is damped by a resilient member (141) positioned directly or indirectly therebetween.

14. An isolator according to any one of claims 3 to 13 when mounted between a sound speaker and a supporting surface.

15. A support for a vibrating apparatus comprising the link or isolator of any preceding claim.
