The invention relates to an inner slider made of one-piece thermoplastic material for hanging and guiding of curtains in tunnel-shaped profile rails consisting of a slider, neck part and disc-shaped push rosette with hanging hook.

Inner sliders are already known which have a sliding piece running in the sliding channel of the curtain rail have, to which one of the clear width and height of the longitudinal slot adapted cylindrical Neck part is connected, which is in a stop piece with a circular cross-section (push rosette) with a hook transforms. In the formation of such inner sliders, it is known to have the push rosette on its underside to design the surface facing the slide rail to be flat or spherical; but one also knows gliders, in which the stop piece or the push rosette has the overall shape of a ball.

A slider is also known in which the slider and the push rosette are disc-shaped and form a truncated cone on the sides facing each other. The slider has on this one Slider has a much larger diameter than the push rosette. On the underside of the push rosette there is an eyelet for attaching a clip.

A slider is also known in which the slide piece and a plate-shaped stop piece are connected Shaft, d. H. the slider neck, is formed much longer than the height of the longitudinal slot of the Slide rail and in which the slider neck protrudes as a hook over the plate, at its end by 90 ° is bent and is provided with a button-like plate at this bend.

The previously known gliders have a very serious disadvantage in that they are in their inclined position with a relatively small point-like or line-like surface area against put the underside of the slide rail and thereby locally a very high pressure on the surface of the Exercise slide rail. This pressure is increased by the fact that when a curtain is pulled back, d. H. if the individual sliders are pushed against each other, the next one in each case Slider engages the stop piece of the previous slider. The lever arms that become effective here increase the contact pressure against the underside of the slide rail. As practice has shown With such sliders, even slight unevenness and dirt on the underside are sufficient the slide rail in order to make the smooth running of the slider very difficult.

The well-known glider with the relatively long neck part also hits against it when it runs at an angle the stop of the previous slider, making it even more firmly against the lower surface of the Slide rail is pressed and the running properties are also significantly impaired.

The above-mentioned disadvantages of the known gliders are particularly evident, if the sliders are constantly attached to the curtain or the curtain or the like, d. H. even when cleaning or washing the parts. As has been established, however, there is a problem with washing There is a risk of the surface being damaged by harsh detergents or deposits of components in the washing liquor of the stop piece rough or at least with regard to the deposition of dirt and dust becomes more sensitive.

The invention is therefore based on the object of providing a slider for a permanent stay on the Curtain, on the curtain or the like. Train that its running properties are not caused by dirt the curtain rail can still deteriorate through washing treatments and that it is against unintentional Solving in a simple manner is practically completely protected.

Starting from a slider made of one-piece thermoplastic material for hanging and Guiding curtains in tunnel-shaped profile rails, consisting of a sliding piece, neck part and disc-shaped push rosette with hanging hook, the diameter of the push rosette is larger than the width of the slider extending transversely to the running direction of the rail consists of the width according to the invention Training in that the push rosette on
