<p>A device for fixing an object (2) on a supporting surface (3) and having means (14,15,16) for adjusting the position of the object (2) comprises a lower part (6) for fixing against the support surface (3), and upper part (7) for mounting on the lower part (6), and locating means between the two parts (6,7) for determining the relative position therebetween in two mutually perpendicular directions in the dividing plane between said parts. The locating means consists of parallel locating strips (17,18) placed on either side of a rectangular cavity (8) in the lower part (6). The position of the upper part (7) relative to the lower part (6) in each direction is adjusted by replacing the two locating strips (17,18) with two other ones of the same composite width but another width ratio between themselves. The upper part (7) is also fixed by means of a fastener (31) to the lower part (6) and the supporting surface (3) and has means (5) for fixing the object (2). Spacers (14) between the lower and the upper parts (6,7) permit adjustment in a direction perpendicular to the dividing plane between the two parts (6,7).</p> |
