The invention relates to a hanger for the movable arrangement of a Curtain, a curtain or tarpaulin on a guide rail, with a Guide element and with a holding body, which fasteners for the Has a curtain, curtain or tarpaulin.

From DE 36 35 422 A1 is a hanger with a hook-shaped Fasteners for a curtain hem and a holding body with two in a guide rail engaging guide elements known.

EP 1 080 675 A1 discloses a hanger with a hook for hanging in a guide element and with a holding body. The holding body has two hinged and one fold of the curtain encompassing thighs. A separate fastening clip is used for clamping the thigh. The hanger has a complicated structure and requires an elaborate tool. Due to the hook, the holding body cannot be held captive on a guide element.

US 5 388 313 discloses a two-part hanger, one Holding body for the detachable fastening of a flat material and a has pivotally connected fastening loop on which the Hanger is hung together with the flat material. The Fastening loop and the holding body are after assembly inextricably linked.

With these known hangers, curtains, curtains, tarpaulins or similar on a guide rail, a tether or the like become. Different guide rails or tethers require that Use of individual guide elements through which the hanger with the Guide rails or tethers is connected. Because the curtains, curtains or tarpaulin are often inextricably linked to the hanger is an insert only on a specially suitable guide rail or a tether possible.

It is an object of the present invention to provide a simple hanger To provide, which is inexpensive to manufacture and with little effort can be used on different guide rails or the like. At the same time the hanger uses curtains, tarpaulins or curtains with high Weight, e.g. for use with car and advertising tarpaulins, tents, stage or industrial curtains.

This task is essentially with the features of claim 1 solved in that the guide element releasably on the holding body is attachable. According to the invention, the overall function of the Hanger, namely holding a curtain or the like, in two Sub-functions separately, namely the attachment of the curtain, etc. on the Hanger itself and the guidance of the hanger on a guide rail or similar. The latter function, performed by the guide element of the Hanger running, can be customized to the used Guide rail or the like. That the guide element is releasably and thus interchangeably attached to the holding body. For the Others can use a curtain or the like on a tether Guide elements on the hanger are used, for example, in the Use of a guide rail. In this way it is not only possible to use the same bracket for curtains on different curtains Guide rails or the like. To be attached, but it is also possible the guide elements, which are subject to a certain amount of wear, easy to replace.

A particularly simple and inexpensive detachable fastening of Guide element and holding body can be achieved by locking or clamping means become.

According to a preferred embodiment of the invention, this Guide element has a T-shaped end with a cross bar for engaging in one End of the holding body. In this way, the guide element is safe fixed in the holding body, so that even large loads through this Connection are transferable.

The inclusion of the guide element in the holding body is thereby relieved that the side of the crossbar facing away from the holding body to the Outer edges are chamfered or rounded.

In a further development of the inventive concept, it is provided that at each Side of the crossbar material reinforcements in the area of the transition into the Guide element are formed. This will make an improved one Force line flow and thus increased strength achieved.

It is also an alternative to the T-shaped configuration of the guide element possible to provide locking pins on the guide element. These are suitable especially for absorbing large forces such. B. when hanging from Stage curtains or large and heavy tarpaulins.

The holding body is advantageously provided with a latching recess and with a Provide groove for engagement of the locking or clamping means. This will make one simple but secure releasable attachment of the guide element to the Holding body allows.

According to a preferred embodiment of the invention, the holding body has a encompassing the guide element at least in some areas Fastening area. The guide element is so in the Fastening area of the holding body added that an unwanted Falling out of the guide element can be avoided.

In further development of this idea, it is provided that the Fastening area parallel to a displacement axis of the curtain or the like lying sleeve, which has at least one in their Circumferential direction first slot and at least one in their Axial direction extending second slot having each other in Connect. One embodiment is particularly preferred which is the first slot over a range of 90 ° to 210 ° of the sleeve extends and the second slot does not extend the full length of the sleeve extends. A guide element, for example a T-shaped end or Has locking pin, can in this embodiment of the mounting area of the holding body through the axial slot in the sleeve and by pivoting the guide element about the axis of the sleeve in brought into position in the circumferential direction of the first slot in which the guide element is held securely in the sleeve. The Replacing a guide element is thus in no time and with lowest possible technical effort possible. At the same time, the at their ends reinforced sleeve absorb large forces.

A Direction of extension of a displacement axis A of the guide rail each exemplified in Figures 1b, 6b, 15 and 19b. The Holding body 3 has two legs 5, 6, which have an upper, ceiling part of the curtain, curtain or tarpaulin - preferably overlap an edge - U-shaped.

The design of the hanger 1 results in a central introduction of the Curtain weight in the guide rail or the like. And thereby one centric stress on the guide element 2. The two legs 5, 6 extend parallel to each other and parallel to the axis of displacement A. the guide rail or the like. and are integral with the holding body 3 arranged. The holding body 3 does not have a center to the shown guide rail provided mounting area 7 for releasable Connection of the holding body 3 with the guide element 2. Furthermore, the Holding body 3 via a branch point 8, from which the two legs 5, 6 out. There is one between each leg 5, 6 Receiving groove 9, into which the curtain, curtain or tarpaulin is threaded can be. The groove points depending on the thickness of the curtain or the tarpaulin, for example, has a width of 1 mm. For a defined attachment are the inside of the legs 10, 11 with a structure 12, in particular one Toothed or corrugated. One lies on one of the legs 5, 6 provided projection 13 of an associated recess 14 on the each other leg 6, 5 opposite.

The fastening area 7 of the holding body 3 is in the direction of the Displacement axis A extending sleeve 15 formed which is integral with the holding body 3 is formed. The sleeve 15 has at least a first one Slot 16 which extends in the circumferential direction of the sleeve. The first slot 16 extends over a range of approximately 90 ° to 210 ° of the sleeve in which enlarged representation of Figures 5a to 5c about half the circumference (180 °) of the sleeve 15. Furthermore, there is at least one second slot 17 in the sleeve 15 provided, which extends in the axial direction of the sleeve 15, d. H. in the direction the axis of displacement A. The second slot 17 essentially opens at right angles in the first slot 16, so that the two slots 16, 17 a define approximately T-shaped opening in the sleeve 15, which with the is enclosed by the sleeve 15 cavity. On the Cavity facing inside of the sleeve 15 are a plurality of projections 18th formed so that the cavity enclosed by the sleeve 15, as in the Figures 5a to 5c shown a substantially cross-shaped cross section having. On the side of the sleeve 15 facing the two legs 5, 6 runs a further slot 19, which extends over the entire length of the Holding body 3 extends and substantially parallel to the Displacement axis A runs.

The holding body 3 also has a through hole or opening 20 for passing a pull rope. Each through hole 20 extends parallel to the axis of displacement A, so that the pull rope through the Holding body 3 can be passed through, and on an end hanger 1 is attachable. One opening at right angles into the through hole 20 Hole 21 is used to screw in a fastener (screw) Securing the position of the hanger 1 relative to the pull rope.

The guide element 2 points in that shown in Figures 1a to 13 Embodiments with a lower T-shaped end 22 in the figures a crossbar 23 on. The crosspiece 23 extends essentially parallel to the axis of displacement A of the hanger 1. The holding body 3 facing outer edges of the crosspiece 23 can be chamfered or as in the Figures are shown rounded. Can on each side of the crossbar 23 for example, with guide elements made of plastic or cast metal parts Material reinforcements 24 in the area of the transition into the guide element 2 be designed to increase the strength in this transition region.

The side of the guide element 2 facing away from the T-shaped end is for slidable connection with a guide rail, a tether, a Rod or the like. For example, in FIGS. 1a to 6b Guide element 2 equipped with a hook-shaped ring holder 25. Further embodiments of the guide element 2 are shown in FIGS. 7 mapped to 13. 7 shows a ring hook 26, FIG. 8 an open one Rope holder 27, FIG. 9 a closed rope holder 28, FIG. 10 a cranked piping hook 29, Figure 11 with a two-axis roll holder 30 two axes 31a, 31b, not shown on each side of the hanger Can carry rollers, Figure 12 shows a uniaxial roller holder 32 and Figure 13 shows a guide element 2 with ball hook 33.

The assembly of a guide element 2 on a Holding body 3 to a hanger 1 using the in Figures 1a to 6b described process steps explained in more detail. First, the holding body 3 firmly connected with a curtain, curtain, tarpaulin or similar. For a guide rail, a tether, a rod or the like, that is now to select a suitable guide element 2, as in FIGS. 1a to 6b shown as an example with a ring holder 25. Fig. 2 shows how now first end of the crossbar 23 in the second, extending in the axial direction extending slot 17 of the holding body 3 is inserted. The length of the second slot 17 is smaller in the exemplary embodiments shown than the length of the crossbar 23.

In Figure 3, the pivoting of the cross bar 23 of the guide element 2 is in illustrates the second slot 17 of the holding body 3. This is through the rounded outer edges of the crosspiece 23 facilitated. Then will the guide element 2, the cross bar 23 is now in the through the sleeve 15 enclosed cavity is moved in the axial direction, so that the end of the ring holder 25 facing the crosspiece 23 also in the first Slot 16 is as shown in Figures 4 and 5a.

By pivoting the guide element 2 relative to the holding body 3 about the longitudinal axis of the sleeve 15, the guide element in its Figures 5c, 6a and 6b brought position shown. The crossbar passes 23 in the cavity enclosed by the sleeve 15, the projections 18, so that the crossbar 23 with the guide element 2 in the shown in Figure 5c Position snaps into place. Passing the projections 18 is facilitated that the sleeve 15 can expand elastically through the further slot 19.

In this position, the guide element 2 is firmly in place by the crossbar 23 Sleeve 15 of the holding body 3 held so that the guide element 2 with a not shown guide rail, a guide rope, a rod or Like. Can be connected. With holders for light curtains with Small cross section of the sleeve 15, the slot 19 can be omitted, since a thin Wall thickness has sufficient elasticity to screw in the cross piece 23 and to allow it to snap into place.

To exchange a guide element 2 for another The guide element 2 and the holding body 3 can be guided easily separate from each other by following the process steps described in reverse order.

FIG. 14 shows a further embodiment of a holding body 3, which is different from differs from the embodiment shown in FIGS. 1a to 6b in that that only one fastening means 4 is provided on the holding body 3. The holding body 3 shown in FIG. 14 is therefore particularly suitable for the Use with light curtains or curtains.

In contrast, Figure 15 shows a holding body 3, which is used for the attachment of heavy tarpaulins or curtains. In this embodiment of the Holding body 3, two fasteners 4 are provided. The size, i.e. the Length, width and thickness, of the holding body 3 and the number of Fastening means 4 can be adapted to the respective requirements. In addition, the holding body 3 has two first slots 16a and 16b and two second slots 17a and 17b. Examples of guide elements 2, which on the Holding bodies 3 shown in FIG. 15 can be fastened are shown in FIGS. 16a to 18 shown. Figures 16a and 16b show different ones Views a ring holder 34 while in Figures 17 and 18 biaxial roll holder 30 and a uniaxial roll holder 32 shown are. Of course, you can also send more individually to one Guide rail, a tether, a rod or the like Guide elements, similar to those shown in Figures 1a to 13 Guide elements are connected to the holding body 3 according to Figure 15.

For connection to the holding body 3 according to FIG Guide elements 2 of Figures 16a to 18 do not have a continuous Transverse web 23, but two locking pins 35a, 35b, which are analogous to the above described procedure inserted into the slots 17a, 17b and through Swiveling in the slots 16a, 16b in the hanging position of the Guide element can be brought.

Different views of another are shown in FIGS. 19a to 19c Embodiment of a holding body 3 shown. In this embodiment of the holding body 3 are each other in the direction of the axis of displacement A. opposite ends of the sleeve 15 each by a bead 36a or 36b completed. In this way it is possible for greater forces to go through the sleeve 15 reinforced by the bead 36 are received. This Embodiment is therefore particularly suitable for extremely heavy curtains or tarpaulins, such as stage curtains or so-called side curtain tarpaulins for trucks.

Furthermore, in FIGS. 19b and 19c there is also a narrowing 37 caused by the two slots 16, 17 defined opening in the sleeve 15. On unintentional pivoting of the guide element 2 from the in Figure 5c position shown in the position of Figure 5a can be avoided. The guide element 2 is thus triple in the holding body 3 Secured falling out: first over the longer one compared to slot 17 Cross bar 23, further over the projections 18 and finally also over the Cross-sectional narrowing 37.

In contrast, with light curtains it is for simplification and Accelerated assembly is also possible, the cross bar 23 of the same length how to form the slot 17. The insertion or insertion of the Crossbar 23 in the sleeve 15 according to Figures 2 to 4 can be omitted. Due to the shorter length of the crossbar 23, however, this can only lower forces are transmitted from the guide element 2 to the holding body 3 become. In the embodiments shown in FIGS. 15 to 18 with Locking pin 35 is used to compensate for the reduced force absorption shortened locking pin 35 possible, not only, as in Figures 16 to 18 shown to provide outwardly facing locking pins 35a, 35b, but to form additional locking pins pointing inwards.

In one embodiment shown in Fig. 20 is on one or both Legs 5, 6 between the holes 21 for riveting or screwing a positioning hole 38 is provided. On the detail in Fig. 21 The insertion tool (rivet plate) 39 shown is then between rivet dies 40 Threaded or retaining pin 41 is provided. If the set screw 41 is unscrewed, the holding body 3 with the positioning hole 38 can thus enter the tool 39 are inserted that the holding body 3 firmly and securely in the tool 39 lies and does not slip when the tarpaulin material or the like is inserted. at overhead handling is also possible for this handling, since the holding body 3 cannot fall out of the tool 39. The pin 41 also secures the situation of the holding body 3 when riveting against unintentional shifting. at Holding bodies 3 without a positioning hole can be used with the insertion tool 39 withdrawn set screw 41 can also be used. 21 are shown in the bores 21 pre-assembled rivets 42, through which the assembly can also be simplified.

The guide elements 2 and the holding bodies 3 are preferably made of Plastic, for example polyamide or PVC. However, it is also possible the guide elements 2 and / or the holding body 3 made of metal, for example to manufacture as metal castings or metal stampings.
