Abstract

An improved shock isolating mounting comprising at least three substantially U-shaped leaf spring members, each leaf spring member comprising at least two leafs arranged to define a space therebetween. In one arrangement, the respective at least three substantially U-shaped leaf spring members are arranged in an array having a substantially equal angular spacing between adjacent spring members.

Claims (27)

1. A mount comprising at least three substantially U-shaped leaf spring members, each leaf spring member comprising at least two leafs arranged to define a space therebetween,

wherein each substantially U-shaped leaf spring member has an upper and a lower end, the upper and lower ends representing respective terminal ends of each leaf of each leaf spring member, and wherein the respective terminal ends of each leaf of adjacent leaf spring members are interleaved relative to each other;

wherein the space defined by adjacent leafs of the leaf spring members is filled with a damping material;

wherein each leaf spring member has a recessed portion at each of its respective terminal ends, the respective recessed portions being configured such that when the leaf spring members are interleaved, the respective recessed portions come into proximity with each other to define apertures at the top and bottom of the mount; and

wherein the mount further comprises inserts, each having a shoulder that is adapted to extend at least partially into a respective aperture at the top and bottom of the mount, the inserts being adapted to receive the shanks of mount securing bolts which extend through the respective apertures at the top and bottom of the mount.

2. The mount of claim 1 , wherein the respective at least three substantially U-shaped leaf spring members are arranged in an array having a substantially equal angular spacing between adjacent spring members.

3. The mount of claim 2 , wherein the at least three adjacent substantially U-shaped leaf spring members are separated by an angle that is substantially 360°/n, where n is a whole number greater than or equal to three.

4. The mount of claim 1 , wherein the mount comprises three substantially U-shaped leaf spring members.

5. The mount claim 1 , wherein the mount comprises four substantially U-shaped leaf spring members.

6. The mount of claim 1 , wherein each leaf spring member comprises two leafs arranged to define a space therebetween.

7. The mount of claim 1 , wherein each leaf spring member comprises three leafs arranged to define a space therebetween.

8. The mount of claim 1 , wherein each leaf is formed from a band of stainless steel.

9. The mount of claim 1 , wherein the damping material comprises a viscoelastic damping compound.

10. The mount of claim 1 , wherein the damping material comprises a wire mesh.

11. The mount of claim 9 , wherein the damping material comprises a wire mesh.

12. The mount of claim 1 , wherein the respective interleaved leafs are connected together via bolts which engage with locking nuts which extend through closure plates provided at either side of the respective upper and lower ends of said leaf spring members.

13. The mount of claim 1 , wherein the apertures defined by the respective recessed portions are substantially concentric.

14. The mount of claim 1 , wherein each of the closure plates each has a corresponding aperture that is in coaxial alignment with the apertures at the top and bottom of the mount.

15. The mount of claim 1 , wherein the inserts are made from comprise nylon.

16. The mount of claim 1 , wherein the mount further comprises one or more caps formed from a resilient material that is/are adapted to be fitted over the head/heads of the mounting bolt(s), wherein the one or more caps are adapted to protect the mount securing bolts in the event of mount bottoming.

17. The mount of claim 16 , wherein each cap is formed from rubber of not more than 60 shore hardness.

18. The mount of claim 16 , wherein each cap has side walls adapted to engage with the head of a corresponding mount securing bolt, and a bulbous dome which defines an air gap between the dome and the head of the corresponding bolt.

19. A mount assembly comprising a plurality of mounts according to claim 1 , wherein the mounts are arranged between spaced apart upper and lower mount rails.

20. The mount assembly according to claim 19 , wherein each mount rail comprises a welded steel transverse beam to which the mounts are attached at their respective upper and lower ends by mount securing bolts and threaded nuts.

21. The mount assembly according to claim 19 , wherein the lower mount rail comprises one or more interface pads which are disposed at each end of said mount rail and which are adapted to bolt to a supporting surface.

22. The mount assembly according to claim 19 , wherein the lower mount rail comprises twistlocks which are disposed at each end of said mount rail and which are adapted to fasten to a complementary aperture provided on a supporting surface.

23. The mount assembly according to claim 19 , wherein the upper mount rail spans a width of the mounting rail assembly and has a twistlock at each end.
