<p>The invention provides a device for adjusting the effective length of a table leg. The device includes an upper and a lower member (10, 12, 14) that is rotatably associated with one another and are biased apart by spring means (20), the upper member (14) including a first downwardly directed ramp (22) spaced apart from a second ratchet ramps (24) associated with the lower member (12) by a wall. The upper member (10) includes one or more pawls (25) adapted to run in the channel between the ramps (22, 24), and including a formation adapted to engage the ratchet when the desired effective length of the leg plus device has been adjusted.</p> |
