APPARATUS FOR ATTACHMENT OF A MOUNT FOR SENSORS, SWITCHING MEANS AND THE LIKE TO RAILS
In the case of an apparatus for attachment of a mount (16) for sensors, switching means and the like to rails (1) comprising a rail claw with claw jaws (3, 4) which can be fitted onto the rail foot from opposite sides, one of which (4) is provided on the mount side and the other (3) can be adjusted relative to it by means of at least one adjusting screw (2) which can be passed through under the rail foot, and devices (5, 7, 10, 11, 12) are provided for adjustment of the distance between the mount (16) and the area where the mount-side claw jaw (4, 6) acts on the rail foot, in order to preset the rail claw for different rail foot widths, at least the claw part (6) on the mount-side claw jaw (4) is connected to the mount (16) itself or to a holding piece (5) seated on it, such that it can be adjusted and fixed in its own right independently of the adjusting screw, and this mount-side claw jaw (4), to be precise its claw part (6), is secured in each preset position integrally by means of for example grooves, which engage in one another, or profiles (11, 12), which have a sawtooth-like cross section, on opposite sides of the claw jaw (6) and of the mount or of the holding piece (5).
