Abstract (en)
[origin: WO02077394A1] The invention relates to a mechanism comprising a casing (9) containing at least two interacting shafts (6) which are nested into each other and which have successive adjustable spaces between them. Each shaft comprises a threaded part (6a) that passes through a nut (11), said nut being housed in the casing and supporting a step support (4). Another shaft (12) is disposed in parallel to the aforementioned shafts (6). Said second shaft passes through the different nuts (11) and is fitted with eccentric members (13) which are connected to the respective nuts (11). Each eccentric member (13) is rotationally fixed to the shaft (12) and co-operates by means of pressure with a head (14) of the associated support (4) in order to adjust the angle of inclination of the support to a pre-determined value. The inventive mechanism can be used to adjust both the variable distances between the nested shafts (6) and to adjust the angle of inclination of the different supports (4) simultaneously, thereby making it unnecessary for different devices to be used for each adjustment.
