Abstract
Two mutually adjoining profile pieces (1a) of equal cross-section are connected by means of a coupling piece (16) which overlaps both of them and is situated in a coupling groove (15). The convexly arched floor of the latter is formed by the underside of a crossbar (5), the top side of which forms a running surface (6) for bearing rollers of running mechanisms. In the downward direction, the coupling groove (15) is limited by lateral holding strips (18a,b) exhibiting flat, inwardly inclined holding surfaces (19a,b), which point towards the floor of the said coupling groove and against which are pressed corresponding contact strips (20a,b) of the coupling piece (16), which coupling piece is braced against the holding strips (18a,b) of each of the profile pieces (1a), by means of, in each case, two tapping screws (17b) pressing against the floor of the coupling groove (15). At the bottom, the coupling groove (15) is adjoined by a guide groove (9) for receiving guide rollers. For the purpose of enabling a particularly stable connection of the profile pieces--for example in the case of a rail supported only punctually by means of sliding blocks, which are disposed in a fastening groove and in which threaded bolts engage--the profile pieces can be provided with two coupling grooves disposed at a distance apart one above the other.
