Abstract

In the case of a device for fixing folds (63 to 66) on curtains or drapes (62) with vertically extending webs which are open at the top and bottom, an inserted fold (64, 65) is held in a slot between two webs (54) . For the purpose of keeping the protruding folds securely and precisely fixed in their shape without making them completely rigid in the fixing area, a fold clamp (2), which can be locked elastically with a support plate (1), is provided, which on the front side ( 51) carries at least two fold clamping devices (52) formed by webs (54) which are aligned with one another and are spaced apart from one another. At least one fold clamping device (52) projects approximately as far as it corresponds to the depth of the folds (63 to 66) to be fixed. The other fold clamping device projects forward by a significantly smaller amount. The folding clamp (2) can be locked at a distance from the support plate (1) with this by means of centrally arranged locking devices and has on both sides of these locking devices elastically deformable wings (72, 73) with their outer longitudinal sides reaching into the vicinity of the support plate, so that the outer folds (63, 66) between the support plate (1) and the wings (72, 73) are held in a clamping manner.

Description

The invention relates to a device for fixing folds on curtains and curtains, with vertically extending webs which are open at the top and bottom, an inserted fold being held in an elastically clamping manner in a slot formed between two webs and projecting into the respective slot on the webs barb-like projections are arranged.

Such a device known from DT-PS 22 27 199 (corresponding to US-PS 3 861 ₀₀ 1) is formed in one piece. This known device has the general advantage that it is relatively simple due to its one-piece construction. Their disadvantage is that the folds are only held on their feet.

From US-PS 3 223 148 a device for fixing folds on curtains and curtains is known, in which the folds are held on a one-piece, made of hard-elastic plastic holding body, on which webs also extending from top to bottom are arranged, and an inserted fold is also held in an elastically clamping manner in the slot formed between two webs and open at the top and bottom. These slots are circularly widened at their inner closed end so that the folds can be held on their fold base by means of a holding rod of circular cross-section. The webs designed as hollow bodies must be so elastic that the circular holding rods can be inserted from the front together with the double layer of fabric. However, this in turn means that it can be pulled out again with the same force with which the curtain fabric and the holding rod are pressed into the slot. Furthermore, the relatively large width of the slot at its inner closed end also results in a correspondingly large distance between individual adjacent slots, so that the holding body as a whole is relatively large and bulky. This in turn leads to the fact that such a holding body cannot be used to carry out a crimp that is tightly summarized. Because of the low security of the wrinkle fixation, there is also the risk that the holding body will become detached from the fabric when the curtain is washed or cleaned.

From US-PS 1 149 628 a device for fixing folds on curtains is known, with which claws are provided which project downwards on a retaining ring which is adjustable in diameter and which is to be guided on a cylindrical curtain rod. A single claw with barbs projecting forward is provided on the side associated with the rear of the curtain, while two finger-like claws with barbs projecting backward are provided on the side facing the front of the curtain. By means of these claws, the curtain material is held in a point-like manner. Through the two front finger-like claws, a fold projecting forward perpendicular to the curtain can be pulled out. Furthermore, only a simple T-fold can be held with this known device. The disadvantage of this known device is that the formation of a so-called head on the curtain, i. H. it is not possible to form a part on the curtain that goes upward beyond the holding device. Furthermore, this known device is not suitable for holding more sensitive curtain fabrics, since, due to the punctiform mounting on the barbs of the claws, there is a risk of tearing the fabric when subjected to a load. In addition, the front finger-like claws are visible when a forward protruding fold is formed, which is aesthetically disturbing.

From DT-PS 22 55 328 (corresponding to US-PS 3 921 696) a holding device for curtains is known in which a hook can be fastened to a holding device by means of pins projecting from a plate of the hook with spherical heads which can be inserted into corresponding openings in the holding body.

The invention has for its object to provide a device of the type described above, by means of which protruding folds are held securely and precisely fixed in their shape without the folds becoming completely rigid in themselves in the fixing area.

This object is achieved according to the invention in that an elastic fold clamp which can be locked with a support plate is provided, which carries on its front side at least two mutually aligned, mutually aligned fold spacer devices, at least one fold clamp projecting approximately as far as the depth the to be fixed folding corresponds, while the other Faltenklemmeinrichtun ^g to a significantly small distance protrudes, that the folding clamp in the distance VOEN the support plate thereto by means of a centrally arranged Veriegeilungeinrichtung be locked on either side of these locking devices resiliently deformable, with its outer longitudinal sides to the vicinity of the Carrier plate reaching wings and that the folding clip in the region of its long sides and the support plate have tooth-like projections assigned to each other.

This configuration according to the invention makes it possible, on the one hand, to hold folds to be fixed in the widely projecting fold clamping device, which extends only over a small area of the total height of the device, in such a way that they are fixed over their full depth. In the other fold clamping device, on the other hand, only the foot is held by one or more folds, so that the folds can already spring open again without changing their position relative to the device. At the transition from the non-folded area of the curtain or the curtain to the folds, a double layer of fabric is firmly fixed between the fold clip and the support plate, whereby at the same time the respective outer layer of the outer folds is precisely fixed. Here, the curtain or the curtain itself is carried by the device. The thicker, H. the heavier the fabric of the curtain or the curtain, the further the wings of the pleated clip are elastically expanded, the stronger the clamping force between the pleated clip and the support plate. Because of the configuration according to the invention, the entire device is located on the back of the curtain and is therefore not recognizable from its visible side.

The fold clip advantageously has an approximately cylindrical segment-shaped cross section. According to a particularly advantageous embodiment, it is provided that at least one pair of elastic webs with protruding outwards on the inside of the fold clip jumps are provided with stop surfaces and that associated locking openings are provided on the support plate with contact surfaces for the stop surfaces.

Furthermore, it is particularly advantageous for the so-called American suspension system if a hook is provided which has at least one row with at least two projecting pins which can be inserted into corresponding openings in the support plate. In order to ensure an absolutely safe but detachable hanging, the hook has a bracket attached to a plate, the free end of which can be connected to the plate in the manner of a safety pin.

The device shown in the drawing consists of a support plate 1, on the front of which a folding clip 2 and on the rear of which a hook 3 can each be detachably attached.

The support plate 1 has a flat, elongated, rectangular shape. On its front side 4 it is provided with tooth-like projections 5, of which a row is provided in the vicinity of the associated side edge 6 and 7, respectively. These rows of tooth-like projections 5 run parallel to one another and to the center line 8 of the support plate 1. The tooth-like projections 5 have the shape of a triangular pyramid, one side surface 9 of which faces away from the associated side edge 6 and 7, projects vertically from the front side 4 of the support plate while the other two side surfaces 1 ₀ , 11 run flat inclined towards the outer edge.

Within the two rows of tooth-like projections 5, a row of openings 12 are again provided parallel to the center line 8 and on both sides at the same distance from it. These each consist of a cylindrical section 13 lying towards the front side 4 of the support plate 1, a cylindrical section 14 of smaller diameter adjoining it, located inside the support plate 1, and a frustoconical section 16 which widens towards the rear side 15 of the support plate 1. At the transition between the cylindrical section 13 and the cylindrical section 14 with a smaller diameter, an annular contact shoulder 17 directed towards the front side 4 is formed.

Along the center line 8 there are three locking openings 18, likewise extending through the support plate 1 from its front side 4 to its rear side 15, of approximately rectangular cross section in plan view. They consist of a narrowest rectangular section 19 lying in the interior of the support plate 1, on the vertical side surfaces 2o of which insertion surfaces 21 adjoin one another at a distance from the front side 4. The side surfaces 20 of the section 19 spring back towards the rear side 15, forming contact surfaces 22 which are open towards the rear side 15, so that an enlarged section 23 is formed here.

A hook 3 has a plate 24, from the top 25 of which a bracket 26 is attached bent backwards and downwards. The bracket 26 is provided with a tapered section 27 in the region of its free end. In the lower region of the rear side 28 of the plate 24 facing the bracket 26, an upwardly open catch 29 is attached to the latter, one side wall 30 of which is provided with a recess 31 in the region of the rear side 28 of the plate 24. By bending the bracket 26 towards the rear 28 of the plate 24 with simultaneous slight lateral deformation, the tapered section 27 of the bracket 26 can be guided past the side wall having the recess 31 and the tapered section 27 can be inserted through the recess 31 into the interior of the box 29 . Due to the elastic expansion of the bracket 26 when relieved, the tapered section 27 lies against the rear wall 32 of the box and is laterally between the Side wall 3o and the opposite side wall 33 set. The hook 3 can therefore be closed like a safety pin.

Attached to the front 34 of the plate 24 are two rows of vertically projecting pins 35, each having a spherical head 36 at its end. The two rows of pins 35 with heads 36 are at the same distance a from one another that the two rows of openings 12 have in the support plate 1. The distance b between two adjacent pins 35 with heads 36 in a row is the same as the distance between two adjacent openings 12 in the support plate 1. The diameter of the pin 35 is slightly smaller than the diameter of the narrow cylindrical sections 14 in the support plate. The diameter of the spherical heads 36, on the other hand, is somewhat larger than the diameter of the narrower cylindrical sections 14 and somewhat smaller than the diameter of the further cylindrical sections 13. When a connection is made between the hook 3 and a support plate 1, the heads 36 become into the frustoconical sections 16 pressed in, causing the heads to deform slightly elastically so that they can be pushed through the narrower sections 14. In the other cylindrical sections 13, they spring back up elastically and lie behind the contact shoulders 17, as a result of which a very firm but, with the greatest effort, detachable connection between the hook 3 and the support plate 1 is produced. Since a relatively large number of openings 12 are provided on the support plate 1 in each row, the hook 3 can be very difficult different heights are attached to the support plate 1.

The folding clip 2 has an elongated, elastically deformable clip part 37, approximately rectangular in plan view, which - in cross section - has approximately the shape of a ring cylinder segment. The fold clip 2 is constructed symmetrically to a plane of symmetry 38. On the inside 39 of the bent bracket member 37 respectively in pairs projecting elastic webs 4 _0, attached 41 having at their free ends outwardly projecting barbs 42 43rd These barbs 42 and 43 have inclined surfaces 44 which run away from the inside 39 and stop surfaces 45 which face the inside 39. The three pairs of webs 4 _0, 41 are at the same distance c attached to each other as the locking apertures 18 in the support plate 1. The length of the webs 4o, 41 is slightly smaller than the length of the locking openings 18. When the folding clamp 2 with the support plate 1 is to be locked, these two parts are pressed against one another in such a way that the inclined surfaces 44 bear against the insertion surfaces 21 of the support plate 1. In the event of a force directed against one another, the webs are thereby moved elastically against one another, that is to say towards the plane of symmetry 38, by using the free space 46 located between them. After the barbs 42, 43 have been pushed through the narrowest section 19 in the support plate, the webs spring open again, so that the abutment surfaces 45 of the barbs 42, 43 lie against the contact surfaces 22. This is the pleated clip 2 and the support plate 1 locked tightly together. A release of this lock is only possible in such a way that the webs are bent back together so that the barbs can be pulled out through the narrow section 19.

On the two long sides 47, 48 of the clamp part 37, a series of tooth-like projections 49 is attached, which are identical to the projections 5. The distance d between the two rows of projections is the same as in the case of the support plate 1. The individual projections 49 are only arranged such that they come between two adjacent projections 5 of the support plate 1 when the fold clamp 2 is locked with the support plate 1. In particular, these projections 49 thus have mutually facing side surfaces 5 ₀ lying parallel to the plane of symmetry 38.

The length of the webs 4ö, 41 on the one hand and the curvature of the clamp part 37 is selected such that when the fold clamp 2 is locked with the support plate 1, some air is still left between the respective tips of the projections 5 and 49 and the associated front side 4 of the support plate 1 and the longitudinal edges. 47, -48 of the folding clip 2.

On the front side 51 of the clamp part 37, two fold clamping devices 52, 53 are attached at a distance from one another. These in turn consist of two spaced apart webs 54 and 55, which are provided in the region of their free ends with tooth-like projections 56, 57 directed towards each other. These tooth-like projections 56, 57 have on their outer side inclined insertion surfaces 58, 59 towards the front side 51 of the clamp part and on their side lying towards the front side 51 approximately perpendicular to the plane of symmetry 38 side surfaces 6 ₀ and 61; the tooth-like projections 56, 57 are thus designed like barbs. The webs of the fold clamping device 52 protrude much more from the front side 51 than the webs 55 of the fold clamping device 53.

If four protruding folds 63, 64, 65, 66 are to be formed and fixed at the upper edge of a curtain or a curtain 62, then these folds are formed with appropriate gathering of the fabric and the three between the two middle folds 64, 65 and at the transition to the two outer folds 63, 66, the fold feet 67, 68, 69 are pushed with a corresponding widening of the fold clamping device 52 between their webs 54 up to the front side 51 of the fold clamp 2 located between the webs 54.

After relieving the webs 54, they rest elastically against one another and hold the fabric firmly with the tooth-like projections 56 so that it cannot be pulled out again without the webs 54 being bent apart.

Simultaneously or subsequently, the middle fold foot 68 is pushed between the webs 55 of the smaller upper fold clamping device 53, where it is then likewise secured against being pulled out. On closing the fabric of the curtain or the curtain 62 along the longitudinal sides 47, 48 of the folds bracket 2 is folded, so that between these longitudinal edges 47, 48 and the webs 4 _0, 41 each have a double ply 7o, 71st Subsequently, the pleated clip 2 is locked in the manner already described with the support plate 1, the two double fabric layers 7 ₀ , 71, each forming an outer pleated foot, being firmly secured between the support plate and the pleated clip against being pulled out.

The thicker, H. the heavier the fabric of the curtain. of the curtain 62, the greater the locking forces in the fold clamping devices 52, 53 and between the clamp part 37 of the fold clamp 2 and the support plate 1, since the webs 54 and 55 and the elastic wings 72, 73 of the clamp part 37 depend on the thickness of the fabric are elastically deformed.

The support plate 1, the folding clip 2 and the hook 3 are each made in one piece from a hard elastic thermoplastic.

The hook 3 can be attached to the support plate 1 at any height, as described. Then the entire curtain or the curtain 62 is securely but releasably attached to a curtain rail according to the so-called American system by means of the hook.

At the upper end of the support plate 74 are aligned with each other and directed towards each other pins 75, 76, by means of which a fastening on roll or slide hangers is possible, as described and described in detail in DT-OSes 24 53 46o and 25 42 963 (corresponding US Serial No. 631 197). Furthermore, this configuration makes it possible to hang ready-made curtains or curtains, that is to say permanently provided with a device according to the invention, for hanging up or hanging down and / or for washing in a device as described in DT-OS 25 53 834 (corresponding to US Serial No. 745 984) is known.

The support plate 1, folding clip 2 and the hook 3 are expediently made of alkali and light-stable plastic, such as. B. made of a polyamide. As can be seen from the drawing, the device is long in relation to its width, so that all of the pleat feet can be summarized relatively tightly, but on the other hand a sufficient fixing and holding length is available.

In order to give the folds 63 to 66 of the curtain or the curtain 62 a good stand, ie in order to make these folds sufficiently dimensionally stable, a knitted or woven stiffening band 77 is always processed at the same time when folding, which is shown in FIG. 12 only in the side Areas are shown so as not to disturb the clarity of the drawing. It lies close to the back of the fabric, so it also extends along the folds 63 to 66 on the inside thereof. Such a stiffening band 77 will generally be so wide that it extends from the upper edge of the curtain to below the lower pleat clamping device 52. However, it can also be particularly important a curtain is simply a lining material attached to the back of it. As a rule, such a stiffening tape will be sewn onto the curtain or the curtain 62.
