Abstract

A table 2 is provided with a table top 4 and adjustable legs 6. The adjustable legs 6 are pivotally attached to the table top 4. An adjuster 10 is pivotally attached to the adjustable leg 6 and the table top 4 to independently allow the angle and height of each of the adjustable legs 6 to be altered such that the table top 4 may be levelled on uneven ground.

Claims

1. A table mountable on an uneven surface, said table comprising:

(i) a table top;

(ii) at least one adjustable leg, said leg having one end pivotally attached to said table top and a second end resting on said uneven surface; and

(iii) an adjuster for independently adjusting each adjustable leg, said adjuster being pivotally attached to said table top and said adjustable leg;

wherein

(iv) said adjuster can be varied to adjust the angle between said adjustable leg and said table top thereby varying the height and angle of said table top such that said table can be leveled on said uneven surface.

2. A table as claimed in claim 1, wherein said adjustable leg pivots in a single plane and said adjuster is a variable length strut with one end pivotally attached to said table top and the other end pivotally attached to said adjustable leg.

3. A table as claimed in claim 2, wherein said variable length strut comprises a central sleeve receiving at its threaded ends oppositely threaded coaxial rods, each said rod being pivotally attached to a respective one of said table top and said adjustable leg such that rotation of said sleeve relative to said rods either draws said rods together or forces said rods apart thereby shortening or lengthening said variable length strut.

4. A table as claimed in claim 3, wherein said sleeve is positioned outwardly of said adjustable leg.

5. A table as claimed in claim 1, wherein said table top comprises a table surface attached to a table top frame, said adjustable leg and said adjuster being attached to said table top frame.

6. A table as claimed in claim 5, wherein said table top frame includes a cross brace at a corner, said adjustable leg being attached to said cross brace and said adjuster being attached to said corner.

7. A table as claimed in claim 1, wherein all of the legs of said table are adjustable legs.

8. A table as claimed in claim 1, wherein said table has four legs.

9. A table as claimed claim 1, wherein said adjustable leg and said adjuster are made of metal.
