Embodiment Construction

[0020] The device of this embodiment comprises an upper element 10 , a lower element 12 and an intermediate element 14 .

[0021] The upper element has a larger inner diameter than the middle and lower elements and can be rotated by means of knurls 16 .

[0022] The intermediate element has a hollow annulus 18 for receiving such as Figure 4 The lower part of the spring 20 housed in the upper element is shown. A series of ramps 22 extend downwardly from the intermediate member, in this regard with reference to Figure 5 .

[0023] The lower element also has a series of ratcheted ramps 24, referenced in Figure 5 shown in .

[0024] Pawl 25 (in image 3 Only one of the is visible, in Figure 4 Two of them are visible) extending through the opening 26 of the intermediate element, so that the pawl can be positioned in the channel defined between the ramp 22 of the upper element and the lower element 24 .

[0025] The assembled unit is secured in the cooperating formation 2...

Abstract

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.

Description

technical field [0001] The invention relates to a device for adjusting the effective length of the legs of a table with multiple legs, especially a table with four or more legs. But it is also suitable for other furniture items such as beds, chairs and the like. Background technique [0002] One or more table legs losing contact with the floor due to unevenness in the floor can lead to a tendency for tables, especially in restaurants, to wobble or wobble, which is a source of annoyance and embarrassment. Any attempt to overcome this problem by moving the table is usually unsuccessful, many diners often place folded paper balls, wedges and the like under one of the legs not touching the floor, this sometimes works, But it usually results in the paper and wedge being thrown on the floor after a while and the same trouble happening again. [0003] Cam mechanisms have been proposed to solve this problem, which can be actuated with the feet and thus raise or lower the table leg...
