Abstract
A vibration mounting comprises a base member (10) for mounting to a mounting location and a support member (14) for supporting a load. The support member is spaced apart from the base member in a load-bearing direction by a vibration-isolating element (18) of a resilient material. The vibration mounting has a centre-line in the load-bearing direction. The vibration-isolating element comprises a plurality of lobes (24) on each side of a plane passing through the centre-line. Each lobe (24) extends from the base member (10) towards the support member (14) and also extends in a lateral direction different from that of other lobes. Each lobe (24) has an upper surface engaging the support member and at least one free surface.

A vibration mounting comprising a base member for mounting to a mounting location and a support member for supporting a load, the support member being spaced apart from the base member in a load-bearing direction by a vibration isolating element of a resilient material, the vibration mounting having a centre-line in said load-bearing direction;
- wherein the vibration isolating element comprises a plurality of lobes on each side of a plane passing through said centre-line, wherein each lobe extends from the base member towards the support member and also extends in a lateral direction different from that of other lobes, and wherein each lobe has an upper surface engaging the support member and at least one free surface.
A vibration mounting comprising a base member for mounting to a mounting location and a support member for supporting a load, the support member being spaced apart from the base member in a load-bearing direction by a vibration isolating element of a resilient material,
- wherein the vibration isolating element comprises a plurality of lobes, each lobe extending from the base member towards the support member and also extending in a lateral direction different from that of other lobes;
- wherein the support member comprises at least one buffer member extending towards the base member between adjacent lobes of the vibration isolating element such that the buffer member contacts a resilient material buffer secured to the base member when vibration displacements exceed a first predetermined amplitude in a first direction;
- and
- wherein the vibration mounting further comprises a secondary buffer for further increasing resistance to displacement beyond a second predetermined amplitude of vibration displacement in the first direction.
A vibration mounting comprising:
- a base member for mounting to a mounting location;
- a support member for supporting a load, the support member being spaced apart from the base member in a load-bearing direction by a vibration isolating element of a resilient material, the vibration isolating element comprising a plurality of lobes extending from the base member towards the support member;
- and
- buffer means comprising a first buffer for increasing resistance to displacement of the support member relative to the base member in the load-bearing direction beyond a positive displacement threshold and a second buffer for increasing resistance to a negative displacement beyond a negative displacement threshold.
