Description

The invention relates to a pleated curtain for covering an opening delimited by a frame, in particular for covering a window or door opening.

Pleated curtains on windows are used for sun protection. It is known to arrange a prefolded pleated fabric between two fabric retaining strips and to attach it to a window or door on the inside. Here, the upper and lower fabric folding rail are movably mounted, so that the pleated curtain as desired interconnects the entire window opening or even partial surfaces. The fabric holder strips can be moved manually here. For this purpose, handles are provided on the fabric support strips. The movement of such known pleated blinds via pull cords or pull chains, which are performed several times starting from a fabric support strip through the entire fabric. For this purpose, appropriate rows of holes in the pleated fabric are provided. Light can be introduced through the holes in these holes, and in addition, the string guide is visible to the fabric when the fabric is light, which is undesirable.

Object of the present invention is to provide a cordless Plisseevorhang available that is simple and versatile.

This object is achieved with a Plisseevorhang with the features of claim 1. Advantageous embodiments are specified in the subclaims.

The new pleated curtain serves to cover an opening, in particular a window or door opening and is preferably arranged on the inside. Such an opening is normally closed by a transparent glass or plastic disc translucent. This pane is held in a frame, for example in a window or door frame. To cover the opening a pleated fabric of the pleated curtain is guided in a plane parallel to the disc. So that the fabric remains in a plane parallel to the disc and is not arched outward or outward, the fabric is guided edge. It has at its two edges a row of holes for the marginal guidance by means of wires, ropes or rods. This row of holes is achieved by folding the pleated fabric accordion-like as a package and then punched at both ends. The fabric can be arranged steplessly at different heights in front of the opening. For this purpose, the fabric web is connected to two fabric retaining strips, for example with an upper and a lower fabric retaining strip. By a manual force on one of the two fabric retaining strips, the fabric can be moved continuously to cover the opening as desired. This is made possible by the fact that the fabric-holding strips are held and guided end-to-end displaceable. For holding the fabric-retaining strips, these have at their two ends means for a frictional connection with a holding element. Such a holding element is provided on the sides of the opening.

In a rectangular opening, these holding elements are arranged on the left and right side of the opening, namely parallel to the left and right frame side. The two fabric support rails are horizontally aligned and can be moved vertically up or down.

In a preferred embodiment, the holder of the two fabric retaining strips takes place by clamping connections between the ends of the fabric retaining strip and an associated retaining element. For such a clamping, a clamping element is preferably provided at the two ends of the fabric retaining strip, which cooperates with a holding rod or retaining rail as a holding element. Such a clamping element may be formed integrally with the fabric retaining strip or be connected as a separate part at the end with the fabric retaining strip. The design of the clamping element depends on the cross section of the support rod and the shape of the fabric retaining strip.

In a further embodiment of the cordless pleated curtain, the holding of the two fabric holding strips is effected solely or additionally by magnetic force. For this purpose, a magnet is preferably arranged on the fabric-holding strips, for example, attached via an adhesive connection to the outside of the fabric-holding strip facing the window, or held in a receptacle on the fabric-holding strip in a form-fitting manner. As a holding element acts in this case provided on both sides of the opening and extending along the left or right side of a rectangular frame support rail.

In the case of a rectangular opening, for example for a window or a door, the vertically extending holding elements are provided on both sides along the left or right side of the frame. These holding elements may be round rods made of solid material with different cross-section such as round, oval or polygonal, around pipe rods, profile bars or other forms of Hold rails act. These retaining elements are the end, so set at the top and bottom of the frame or a support rail can also be glued to the inside of the disc or attached to the frame. The holding elements may be made of metal, plastic, composite, glass or wood. For a magnetic holder, the holding rail must be ferromagnetic, ie either made of a ferromagnetic material such as iron or steel, or be coated with such a material.

If the retaining elements are, for example, round rods, the clamping element provided in the fabric retaining strips can, for example, be of annular design, with the retaining rod passing through this annular clamping element. In the region of the passage opening of the annular clamping element clamping tongues, clamping lips can be provided or in the simplest case, the clamping between the annular clamping element takes place in that the clamping element sits tightly on the support rod and the frictional forces cause a high holding force. A clamping element may also have a different shape and engage around the holding rod by means of clamping means. In a further embodiment, a clamping element is used which on the one hand has locking means to be clipped onto a retaining rail and on the other hand has locking means for connection to a fabric retaining strip.

The frictional clamping connection of the clamping elements with the support rods or the retaining profile rails are designed so that a movement of the material holding strips connected to the Klenmelementen is easily possible. If, for example, round handrails are used, these handrails at the same time ensure guidance of the fabric support strips which can be moved up or down along these handrails separately from one another and, during this displacement, pull apart or push together the pleated fabric web. The fabric is also guided edge. she owns on both edges of the row of holes for the two handrails, so that the fabric left and right is guided on the support rod.

In further embodiments of the cordless pleated curtain, a holder of the two fabric retaining strips is effected by magnetic force on a retaining rail or by means of clamping on a retaining rail. If such a holder provided, the leadership of the fabric in the same manner as described above, by means of a rod, comparable to the aforementioned support rod, can be effected, which in this case, however, can be very thin. Or such a bar is replaced by ropes or wires which are fixed at both ends to the frame of the window or the door above and below the opening and pass through both the fabric holding strips and through the fabric. If a rope made of an elastic material is used, it is also possible to attach this rope to the fabric-retaining strips, so that it is stretched between the two fabric-retaining strips or provided circumferentially, i. passes through both fabric retaining strips and both rows of holes of the fabric.

Advantageously, the row of holes is covered by a retaining rail or by a retaining rail, which is located immediately behind such a guide the pleated fabric and thus also behind the row of holes of the pleated fabric, and it is a relevant light incidence prevented. Such a guide can on the one hand by the small diameter of the rods used for leadership, ropes or wires and on the other hand by the choice of materials, such as transparent plastic, glass fiber or similar transparent material, move into the background for the viewer and the attention alone on the pleated fabric to steer.

In the Fig. 1 A first embodiment of a pleated curtain 20 is shown partially covering an opening 11 of a window. This pleated curtain 20 leaves can move continuously up or down and so can completely cover the opening 11. Shown is a central arrangement of the pleated curtain 20 in front of the opening 11. In this case, below or above the fabric 22, light can pass unhindered through the window. The fabric web 22 is a pleated fabric web 22, which is connected at the upper edge with the fabric retaining strip 23 and at the bottom with the fabric retaining strip 24. Such a connection can be made by gluing or pinching the fabric edges. The upper and lower fabric retaining strips 23, 24 are independently displaceable up or down. For this purpose, corresponding gripping elements can be provided on the fabric support strip 23, 24.

The fabric support strips 23, 24 are held and guided end. How better Fig. 2 can be seen, the fabric retaining strip 23 and also, but not shown, the fabric retaining strip 24 at its two ends a receptacle 25 for a clamping element 40. This clamping element 40 is configured in this case annular and takes in a through hole, the support rod 32. The clamping connection between the clamping element 40 and the support rod 32 takes place in this case solely by a sufficient frictional engagement. The support rod 32 is provided at the left edge of the opening 11 and extends parallel to the left side of the frame 10. At the right side of the frame 10 at the same distance from the frame 10, a support rod 32 is provided in the same way with a clamping member 40 at the other End of the fabric retaining strip 23 and the fabric retaining strip 24 cooperates. Between the upper fabric retaining strip 23 and the lower fabric retaining strip 24, the retaining rods 32 each pass through a row of holes provided in the fabric web 22. In this case, each fold of the fabric web 22 along the support rods 32, which are simultaneously rods 21, 21 'for guiding the fabric web 22, due to the existing holes 27 out. The rods 20, 20 'are secured by means of brackets 26 on the frame of the window.

In the Fig. 2 Furthermore, a holder of the fabric support strip 23, 24 by means of magnetic force is shown, which would not be necessary per se, since the aforementioned clamping connection between the clamping elements 40 and support rods 32 is sufficient to hold the pleating process 20. For the non-positive magnetic connection, a magnet 50 is attached to the outside of the fabric retaining strip 23 by means of an adhesive bond 51. This magnet 50 and thus also the fabric support strip 23 are held on a support rail 30. This is a running from the upper edge to the bottom of the window steel rail, which is either attached to the frame of the window or glued as in this case to the glass 12 of the window It is also possible the support rail 30 integral with a spacer of Train window. The holding force is so great that the pleated blind 20 can be held on both holding rails 30, 30 ', namely by the magnets 50 provided at both ends of the upper fabric holding strip 23 and by the two magnets 50 provided on the lower fabric holding strip 24. This holding force is so large that a manual displacement of the fabric support strip 23, 24 is possible.

In the present example according to Fig. 1 and 2 are for holding the pleated curtain 20 two positive connections of the fabric support strips 23, 24 on the one hand by clamping on the support rods 32 and on the other by magnetic force on the support rails 30, 30 'shown. For holding the pleated curtain 20, however, a frictional connection is usually sufficient, ie either a clamp or a holder by means of magnetic force. If the clamping is dispensed with in the present example, support rods 32 for holding the fabric support strips 23, 24 are no longer needed, but still rods 21, 21 'for guiding the fabric 22. These rods 21, 21' can therefore be replaced by thinner rods 21 , 21 ', ropes or wires are replaced, since they do not have to assume a holding function, but are used exclusively to guide the fabric 22 of the pleated curtain 20.

Another example of a pleated curtain is shown in detail in the Fig. 3 shown. Here, the fabric support strips 23 and 24, shown only the upper fabric support strip 23, the end each held slidably via a clamping connection to a holding element. As a holding element, a retaining rail 31 is shown, which is arranged on the glass pane 12 adjacent to the frame 10. This retaining rail 31 runs parallel to the left frame side 10 comparable to the retaining rail 30, shown in FIG Fig. 1 , A similar retaining rail 31 is provided on the right side of the opening 11 of the window, comparable to the arrangement of the rail 30 'in Fig. 1 , Both retaining profile rails 31 have a fastening strip 310, with which it is attached to the glass pane 12 by means of an adhesive bond. Such a retaining rail 31 may also be fixed to the frame 10, for example via an adhesive connection or via a screw connection. In this case, corresponding holes are provided in the mounting bar 310 or the mounting bar 310 is by means of brackets 26, as in Fig. 1 shown set. From the mounting rail 310 of the retaining rail 31 protrudes perpendicular to the front, ie away from the glass pane 12, a web 311, the end two locking strips 312, 313 has. At this locking strips 312, 313 of the clamping head 410 of a clamping element 41 is held.

The clamping elements 41 serve the displaceable mounting of the fabric support strips 23, 24 on the two retaining rails 31, ie at its two ends, the fabric support strip 23 and 24 releasably connected to such a clamping element 41 and slidably held in this way on the retaining rails 31. The clamping elements 41 are provided for connection to the retaining rail 31 with a clamping head 410 and for connection to the fabric retaining strip 23, 24 with a support body 420. The following is based on the Fig. 3 and the Fig. 4 only the connection with one end of the fabric support strip 23 explained. In the same way the connection of the other end of the fabric support strip 23 or the connection of the fabric support strip 24 with the retaining profile rails 31.

For connection to the retaining rail 31 of the clamping head 410 of the clamping element 41 has a terminal strip 411 and a clamping hook strip 412, which include a groove 414 between them, in which the web 311 of the retaining rail 31 with its locking strips 312 and 313 recording. For fastening the clamping element 41, this is applied with the terminally crowned terminal strip 411 behind the locking strip 312 and pressed the clamping element 41 against the retaining rail 31 until the hook strip 412 snaps behind the locking bar 313. For better support and guidance of the clamping element 41, a locking bead 413 may be provided adjacent to the hook of the hook strip 412. The above-described clamping connection of the clamping element 41 with the clamping head 410 on the retaining rail 31 is designed so that the clamping element 41 along the retaining rail 31, i. vertically along the opening 11 of the window, is displaceable. In order to facilitate mounting of the clamping element 41 adjacent to the frame 10, the clamping head 410 of the clamping element 41 has a bevel 415.

For connection to the fabric support strip 23 of the support body 420 of the clamping member 41 is provided, which - as better Fig. 4 to see - two hook strips 421, 422 facing away from the disc 12 of the opening 11. These hook strips 421, 422 are used for clamping connection with the fabric support strip 23. In Fig. 4 the clamping connection between the support body 420 of the clamping element 41, in particular between the hook strips 421, 422 and the fabric support strip 23 is shown, which has a clamping bead 236 for this clamping connection on its upper side 231 and on its underside 233. Such an embodiment of the fabric support strip 23 makes it possible in a simple manner Press fabric holder strip 23 on the mounted on the retaining rail 31 clamping elements 41 from the front.

The fabric-holding strips 23, 24 are thus held slidably on the retaining profile rails 31 via the clamping elements 41, and with the fabric-holding rails 23, 24 the fabric web 22, as in FIG Fig. 1 shown, moved accordingly. For the fabric 22 has the in Fig. 4 Cloth guide rail 23 shown a receptacle 237. For assembly, the pleated fabric web 22 can be pushed concertina like a package and inserted into the receptacle 237. The fabric web 22 can then unfold at the upper fabric support strip 23 downwards, namely via an opening on the underside 233 of the fabric support rail 23, wherein the upper edge of the fabric web 22 is held in the receptacle 237 of the fabric support strip 23. The same applies to the lower fabric rail 24, where the opening is provided at the top. In the example Fig. 4 is the profile cavity of the fabric support rail 23, which is surrounded by the top 231, the back 232, the bottom 233 and the front 230 of the fabric support rail 23, by two oppositely extending ribs in the lower receiving space 237 for the fabric 22 and in an upper receiving space 238th divided. The upper receiving space 238 may be the determination of end-side closure elements, which in the Fig. 6a and 7a are shown serve. In addition, the in Fig. 4 shown fabric retaining strip 23 a handle 234. This can be provided over the entire length of the fabric rail or only in the central region of the fabric support strip 23 as a handle element. This handle 234 facilitates the up and down sliding of the fabric support strip 23 during the displacement of the fabric web 22. In addition, in the fabric support strip 23, the front side 230 is extended upward to a Abschirmleiste 235. This shielding strip 235 is for decorative purposes only. Namely, if the upper fabric retaining strip 23 is displaced upwardly along the retaining profiled rails 31, a displacement up to the upper end of the retaining rail 31 is not possible in this exemplary embodiment, since at the upper and lower end of the retaining rails 31, a cable holder 60 is fixed, to which the clamping elements 41 together with the fabric support strip 23, for example, in the uppermost or lowermost position. These cable holders 60 become invisible to the viewer of the curtain behind the shielding strip 235 of the fabric support strip 23. The length of the Abschirmleiste 235 depends on the thickness of the cable holder 60th

The in Fig. 5 shown rope holder 60 is provided at both ends of a rope and is used to open the rope for lateral guidance of the fabric 22 along the frame 11. The rope replaces the in the Fig. 1 The cable holder 60 is connected to the upper and lower ends of the retaining rail 31. This cable holder 60 is pressed onto the retaining profiled sheets 31 and held via a clamping connection, to which he has a clamping head 62. In order to allow spreading of the two terminal strips of the clamping head 62 during pressing, a slot 63 is provided between terminal strips in this example. Through the cable holder 60, namely in a vertical orientation, runs a cable receptacle 61. A correspondingly parallel to the left and right side of the frame 10 extending cable can be determined by means of a plug in this cable receptacle 61. Such a plug can additionally be anchored by means of a fastening element via a bore 64 in the cable holder 60. The stretched between an upper and lower cable holder 60 rope for the guidance of the fabric 22 extends, in an analogous manner to the execution by means of the rods 21, 21 'in Fig. 1 through the row of holes of the fabric web 22, each fold of the fabric web being provided with a hole 27. Furthermore, a corresponding bore 239 at the two ends of the fabric support strips 23, 24 is provided for the cable, shown in FIG Fig. 3 on the left side of the fabric support strip 23. If a closure element 70 or 80 is provided at the two ends of the fabric support strips 23, 24, then these closure elements 70, 80 corresponding holes 73, 83 for the cable feedthrough. Instead of ropes thin rods or wires for guiding the fabric 22 can be provided in this example, too.

For a decorative finish of the fabric support strips 23, 24 preferably closure elements 70 or 80 are provided. A simple closure element 70 is in the Fig. 6a and 6b shown. It is inserted with one end, the plug-in arm 72, in the receptacle 238 of the fabric-holding strips 23 and 24 at the end. In Fig. 6a and Fig. 6b the upper fabric retaining strip 23 is indicated in dashed lines. At the other end, the closure element 70 has a covering 71 which is flat over the entire cross-section of the profile cavity of the fabric support strip 23 Fig. 7a, 7b another closure element 80 is shown. Again, the plug-in arm 82 is inserted into the receptacle 238 of the fabric support strip 23 or in the same manner, which is not shown, in the fabric retaining strip 24. A cap 81 is pushed over the end of the fabric retaining strip 23. This cap has a cross section which is adapted to the cross section of the fabric retaining strip 23.
