Abstract

The present invention relates to a stabilising device for stabilising an object having a plurality of support elements on a surface, particularly objects that are moved frequently such as garden furniture or the tables or restaurant terraces. The stabilising device comprises a plurality of fluid-containing compartments which are in fluid communication with each other by way of a restricted flow mechanism such that they are each variable in height in response to the amount of fluid contained therein and are located between the support elements and the surface. The stabilising device eliminates the requirement for using a valve to control the flow of fluid by using the restricted flow mechanism comprising a plurality of interconnected narrow-bore hoses.

Claims

1. A stabilising device for stabilising an object having a plurality of support elements on a surface, the stabilising device comprising a plurality of fluid-containing compartments wherein each fluid-containing compartment

is in fluid communication with the other fluid-containing compartments by way of a restricted flow mechanism;

is variable in height in response to the amount of fluid contained within the fluid-containing compartment and

engages a support element of the object such that the weight of the object acts on the surface through that fluid-containing compartment characterised in that

the restricted flow mechanism comprises a plurality of interconnected narrow-bore hoses;

wherein each fluid-containing compartment is retained within a housing, and wherein the housing includes a support element engaging section and a surface engaging section which is slidably mounted in the support element engaging section.

2. A stabilising device as claimed in claim 1 in which the narrow-bore hoses have an internal diameter of approximately 2 mm.

3. A stabilising device as claimed in claim 1 in which the narrow-bore hoses are interconnected by way of a central filling device.

4. A stabilising device as claimed in claim 1 in which the surface engaging section of the housing comprises a boss which abuts against the fluid-containing compartment.

5. A stabilising device as claimed in claim 1 in which the fluid-containing compartment comprises a flexible bladder.

6. A stabilising device as claimed in claim 5 in which the bladder is substantially hemispherical in shape.

7. An table having a plurality of support elements wherein the table is fitted with a stabilising device comprising:

a plurality of fluid-containing compartments wherein each fluid-containing compartment

is in fluid communication with the other fluid-containing compartments by way of a restricted flow mechanism;

is variable in height in response to the amount of fluid contained within the fluid-containing compartment and

engages a support element of the object such that the weight of the object acts on the surface through that fluid-containing compartment characterised in that

the restricted flow mechanism comprises a plurality of interconnected narrow-bore hoses;

wherein each fluid-containing compartment is retained within a housing, and wherein the housing includes a support element engaging section, fitted to a respective one of the plurality of support elements of the table, and a surface engaging section which is slidably mounted in the support element engaging section.
