Abstract
An attachment arrangement for attaching an object (4), for instance a rail, such as a support rail, brake rail, mounting rail or the like, onto a piston-cylinder control device (1), the cylinder of which has two undercut grooves (3) extending along at least one of its sides, these grooves being parallel with one another and therewith also with the cylinder axis. The object (4) is provided with two parallel ridges or keys (5), each of which is intended for locking coaction with a respective undercut groove (3). At least one wedge-shaped, elongated device (6) is arranged between the outside of the cylinder (1) and the object (4), in connection with each pair of coacting grooves (3) and ridges (4). Means (9) are provided for moving the wedge-shaped devices (6) in a direction transversely to the cylinder axis, so that these devices (6), in engagement with oblique surfaces (7) on the cylinder (1) and/or the rail (4), will fixate the rail in a position parallel with the cylinder axis.
