ABSTRACT:
The present invention concerns an anti-friction device for the sliding of cloth rings of curtains, pelmets and similar.
It is known that at present users like to replace the conventional wood, metal or plastic sliding rings on the support for curtains, pelmets and similar with corresponding rings produced with the same cloth and/or color shade of the curtains.
This solution shows the disadvantage that the deformability of said rings and their considerable friction along the supports don't allow an easy sliding of the curtains.
It is the aim of the present invention to completely solve above mentioned inconvenience by means of a device which maintains the possibility of using aesthetically pleasant cloth rings and allows an easy sliding thereof along the support, as if they were of wood, metal or plastic, greatly reducing the friction.
The aim set forth is reached by means of the device according to the present invention, consisting of an element out of rigid plastic material or other kind, having a curving corresponding to the one of the lateral surface of the support, and provided with means for being applied in the internal upper portion of each cloth ring, so as to be arranged between the ring and the support, helping the reciprocal sliding and transforming the friction into a rolling friction similar to the one of the conventional wood, plastic or metal rings. Furthermore, the device has minimal dimensions so that it may be housed inside the cloth eyelets of already existing curtains, into which no structure of long shape could be inserted.
