The invention relates to an improvement and others Design of roll or slide hangers, in particular for centrifugal curtains and curtains, with an elastic hook that can be closed to form a hanging loop, which at its free end has a Has a barb-like acting end shape, which is under the spring action of the hook material used and under the influence of the curtain or curtain load, form-fit into the recess one of the roller or the sliding body ίο bearing head part engages.

In the known designs of such suspension eyes, the free hook end has a conical in contrast to a cylindrical or slightly conical tapering hook shaft Head on, which in its closed position in a lateral cylindrical recess of the hanger head engages and rests with its shoulder on a counter shoulder in the recess. To the cylindrical The head recess is closed by an open, likewise cylindrical, on the narrow outside of the head Groove into which the shaft section extending behind the end of the hook shank at Closing the loop occurs from the side. You can do this by pressing your finger against the lower bow of the eyelet free hook end can be lifted from its head rest. But since the hook head is in the free If space overhead pushes forward, it has to be swiveled to the side by reaching out with your hand will. Since, however, as already mentioned, the groove receiving the hook shaft is narrower than the Channel diameter, this can only be done with a certain amount of compulsion. This circumstance and the The small dimensions of the hook make the average user of the hangers considerable Trouble.

The situation is similar with another known hanger in which the free hook end is provided with a spherical head, inserted into a cylindrical recess of the hook head and is held there like a pushbutton by a locking bead. The snap fastener is proportionate weak and here, too, reopening and closing the eyelet is cumbersome.

The invention eliminates the disadvantages of the known hanger and consists in that the head part of the hanger above the locking recess for the locking hook end or directly above the in its closed position located hook end an obliquely outwardly extending stop surface or - Has edge that pushes it laterally outward when it is lifted out of its locking recess and Roll or slide hangers for sling curtains and curtains

this opens the eyelet. All that is needed is a light pressure on the lower eyelet.

In the drawing, the subject matter of the invention is shown in an exemplary embodiment. It shows that new hanger as a roll hanger

F i g. 1 in open and

F i g. 2 in the closed state, in side view,

F i g. 3. a section along the line III-III of the Fig. 2 and

F i g. 4 is an end view of the closed hanger, seen from the closing side.

The hanger consists of a z. Example, of two halves la, Ib composite U-shaped head portion and a fixed between these hook part 2 with a resilient hook portion 3, which at its free end, an acute-angled inwardly directed barbs. 4 The downwardly open U-recess 5 tapers strongly conically upwards and ends in a cylindrical bearing eye 6 in such a way that the transition point 7 of the recess 5 into the eye 6 is somewhat narrower than the diameter of the bearing eye.

This is so that you can push a roller body 9 made of one piece with its axis 8 under slight pressure into the bearing eye 6 from the side, the straight extension of the edge 5 a of the U-recess 5 opposite the closing part of the head through the adjacent edge 2a of the hook part 2 serves as a guide to facilitate the insertion of the roller 8, 9.

In which the edge 5 α opposite part of the hanger head is a barb end 4 adapted to the hook portion 3, open on its outer side angled recess 10 provided in which the barb 4 can then intervene just when the hook portion 3 approximates a

assumes a vertical position bent towards the hanger head, as shown in FIG. 2 shows.

This also results in the handling and mode of operation of the hanger described and shown. To close the eyelet, you only need to exert a slight pressure on the lower left corner E (Fig. 1) of the hook part in the direction of the arrow χ , whereupon the lower approximately horizontally lying hook section 3 α pivots around the bend A and the barb 4 so far opposite the recess 10 is raised so that it can be reached by light finger pressure in the direction of the arrow y of FIG. 1 and immediately after that the pressure in the direction of arrow χ when the lever arm 3 a springs back into the recess 4 engages.

Opening the closed eyelet is even easier. One only needs to go back to FIG. 2 exert a slight finger pressure on the corner E in the direction of the arrow x ^e. The hook section 3 a is thus pivoted clockwise again, the hook section 3 is raised and the barb is lifted out of the recess 10. Due to the inclined stop surface 10 a according to the invention, it is at the same time displaced in the direction of the arrow ζ and thus the eyelet is opened.

It is preferred to manufacture the hanger entirely from plastic. But it can also be made of metal or of metal and plastic, e.g. B. in such a way that the hook part 2, 3 made of plastic and the head part la, Ib made of metal or vice versa. Instead of the roller 8, 9, a sliding body can also be provided, e.g. B. in such a way that each hanger head half la, Ib also includes a sliding body half made of one piece with this.

Claims (9)

Patent claims: 1. Rolling or sliding hanger for centrifugal curtains and curtains with an elastic hook part that can be closed to form a hanger eyelet, which has a barb-like end shape at its free end, which under the spring action of the hook material and under the influence of the curtain or curtain load forms a positive fit recess of the roller or the slider-carrying head part engages, characterized in that the head part (la, Ib) an outwardly (a 10), obliquely above the is in its closed position the free hook end (3) extending abutment surface or edge which him when it is lifted out of its latching recess (10) it pushes outwards to the side and thereby opens the eyelet. 2. Hanger according to claim 1, characterized in that the free hook end (3) is bent back to form an acute-angled barb (4) and the hanger head (la, Ib) has an equally acute-angled recess (10) adapted to the barb, which is also acute-angled on the narrow side of the head having. 3. Hanger according to claims 1 and 2, characterized by such a design of barbs (4) and head recess (10) that the outer barb edge and the its nearest inclined edge (10a) of the recess (10) in the closed position of the barb are parallel to each other and close to each other. 4. Hanger according to claims 1 to 3, characterized in that the hanger head (la, Ib) has a downwardly open U-shape to which a likewise U-shaped hook part (2, 3 a) which is open towards the head , 3) connects. 5. Hanger according to claims 1 to 4, characterized in that the hanger head (la, Ib) and hook part (2, 3a, 3, 4) are initially made for themselves and then combined to form a single hanger body. 6.

Hanger according to claims 1 to 6, characterized in that the U-recess transition point (7) of the U-recess (5) of the head (la, Ib) in the bearing eye (6) for the roller axis (8) is narrower than the bearing eye diameter is large. 8. Hanger according to claims 1 to 7, characterized in that the free Closing hook legs (3) opposite edges (5 a, 2 a) of the U-recess and the hook part run in a straight line of escape. 9.
