Description

Locking device for windows, doors or the like. Openings

The invention relates to a closure device for windows, doors or the like. Openings with the features in the preamble of claim 1.

Closure devices of this type are known, for. B. from DE 89 09 836, Ul. In this closure device, the curtain sections and their axes run parallel to the retaining bar. The holding strip and the holder run essentially parallel to one another and to the curtain sections. The holder on the z. B. upper end of the curtain is significantly narrower than that at the other end of the curtain, z. B. below, holding strip. The two edges of the curtain, which extend between the holding bar and the holder, run obliquely to the axis of the curtain sections, each enclosing an acute angle with the curtain sections and the holding bar that is less than 90 °. Along the two sloping edges of the curtain each run guide devices that extend from the retaining strip to the holder and attack both. The curtain is approximately trapezoidal in shape. It is designed as a folding or slatted blind or as a roller blind.

Such a known closure device in this configuration and with the aim of essentially completely covering an opening in its covering position is only suitable for appropriately approximately trapezoidal openings up to at most those openings which are approximately rectangular and above and below, for example, by two horizontal ones , equally large, mutually parallel edges and on both sides are delimited by two mutually parallel vertical edges.

The invention has for its object to design a closure device of the type mentioned so that it is suitable for a variety of other contours and / or sizes of openings to their substantially complete coverage in its extended cover position and at least also for such openings which the edges or individual edges or edge parts run arcuately and / or in such a way that this inclined edge with another, z. B. includes approximately horizontal edge, an obtuse angle greater than 90 °. In particular, the design according to the invention also prevents warping sections from being warped and / or overstretched.

This object is achieved in a closure device of the type mentioned according to the invention by the features in claim 1. Due to this serving as a compensating memory for forming at least one compensating element excess of the curtain along its length between the retaining bar and the holder, the curtain is able to adapt to different contours or sizes of openings, so that these in the extended covering position of the curtain in essentially complete can be covered by the latter. The closure device is extremely simple and inexpensive and thus opens up a variety of uses for all possible openings, for. B. also those of vehicles, and in particular those of motor vehicles. Especially openings of vehicles, in particular motor vehicles, have, depending on where they are located, the most varied contours and sizes following the vehicle design, for which, despite a great need, there have so far been no suitable locking devices. The closure device according to the invention, in particular with an approximately pleated curtain, now makes it possible to cover these differently contoured and dimensioned openings and thus z. B. in motor vehicles to provide effective protection against heating and a privacy screen. It goes without saying that even in vehicles, in particular motor vehicles, the various openings present there can be equipped with a closure device according to the invention, ie the openings in the region of the front window and / or rear window and those in the region of the front and / or rear side windows. The curtain of the closure device according to the invention can be adapted on the edge to the contour of the respective openings. Even then it can be folded into its release position and z. B. recordable within the retaining bar when z. B. at least one edge of the opening runs obliquely and at an obtuse angle with an angle greater than 90 ° to the retaining strip or to the curtain sections or their axes.

Further details and advantages of the invention result from the following description, to which reference is made here to avoid unnecessary repetition. The full wording of the claims is not reproduced above solely to avoid unnecessary repetition, but instead is referred to only by mentioning the claim numbers, whereby all these features of the claim are to be considered as explicitly disclosed here and essential to the invention. All of the features mentioned in the above and the following description, as well as the features that can only be inferred from the drawings, are further components of the invention, even if they are not particularly emphasized and in particular are not mentioned in the claims.

The invention is explained in more detail below with reference to exemplary embodiments shown in the drawings. Show it:

Embodiment,

Fig. 10 is a schematic side view of the

Locking device in Fig. 9, but pivoted upwards in the non-functional position and in the opening.

In Fig. 1, a closure device 10 for windows, doors or the like. Openings 11 is shown, which is in its covering position, in which the opening 11 is substantially completely covered. At opening 11 it is any opening, for example one

Window opening, door opening and here e.g. around one of a vehicle window, which can consist of a front or rear or side window of the vehicle. The opening 11 can e.g. that of a side window of a vehicle, in particular a motor vehicle, which e.g. can be closed by means of a disk which can be moved up and down essentially in the vertical direction. The opening 11 is delimited in FIG. 1 at the bottom by a lower edge 12, on the left by a side edge 13, at the top by an upper edge 14 and in FIG. 1 on the right by an arcuate right edge 15, all edges 12 to 15 or some of these can be formed by a frame part not shown here.

1 shows that the lower edge 12 extends approximately horizontally in this example, but this is not mandatory, and that the lateral edge 13 extends at an obtuse angle with respect to the edge 12 which is greater than 90 ° . The upper edge 14 runs parallel to the lower edge 12 and also has a relative offset in FIG. 1 to the left with respect to the lower edge 12. Otherwise, the upper edge 14 is shorter than the lower edge 12. The arcuate edge 15 connects the edge 14 to the lower edge 12. An opening 11 designed in this way is e.g. typical of some front motor vehicle side windows.

Can completely cover the locking means 10, which in its covering position shown in FIG. 1, the opening 11 described substantially comprises a curtain 16 which is formed in particular from Behangsektionen 17 miteinan ^¬ parallel to the about and / or unparallel axes 18 about concertina-like articulated connection, the individual curtain sections 17, for example, each having the same width. The curtain 16 consists, for example, of fabric, plastic or instead it has metallic curtain sections 17 which are in the Area of the respective axes 18 and adjacent edges are hinged together.

The curtain 16 is fastened at one end approximately in the area of the curtain section 17 'there to a retaining strip 19 which runs approximately parallel to the axis 18 of the curtain section 17'. At the other end, the curtain 16 has a holder 20 attached to it, for example in the area of the curtain section 17 ″ there. The retaining strip 19 can be fastened in the area of the lower edge 12, e.g. be arranged invisibly recessed in a longitudinal slot there.

The curtain 16 is adapted to the special shape of the opening 11. Thus, at least one of the two edges extending between the holding bar 19 and the holder 20, i.e. in the example in Fig. 1, the left edge 21 of the curtain at least partially deviating from a line approximately perpendicular to the retaining strip 19 and thereby approximately parallel to the edge 13. The edge 22 of the curtain 16 assigned to the arcuate edge 15 has in the covering position shown the Curtain 16 one of the arc shape of the edge 15 substantially corresponding arc shape.

The length of the curtain 16 between the retaining strip 19 and the holder 20 is provided with an oversize as a compensation store for forming at least one compensation element. This excess would only show up when the curtain 16 is fully extended. However, the excess of the curtain 16 should serve to ensure that the curtain, in the covering position in which the opening 11 is substantially completely covered, adapts to the dimension and the contour of the opening 11 due to the excess and with the formation of at least one compensating element their edges 12 to 15. Thus, the curtain 16 can be arranged in the region of the opening 11 in its covering position in such a way that under substantially complete covering the opening 11, the retaining strip 19 and the holder 20 run according to the course of the edges 12 and 14 with a longitudinal offset and / or non-parallel to each other. In the cases in which the upper edge 14 would run parallel to the edge 12, but also, for example, with a longitudinal offset from one another, the retaining strip 19 and the holder 20 would then be able to run with a longitudinal offset and parallel to one another. The excess of the curtain with the function of serving as a compensating memory for forming at least one compensating element also allows the curtain 16 to be arranged in the covering position in the region of the opening 11 such that an edge, for example the edge 21, of the curtain 16 with respect to the retaining strip 19 extends at an angle greater than 90 °. The curtain 16 can thus be arranged in the area of the opening 11 in its covering position in such a way that a curtain-side compensation with adaptation to the contour and / or size of the opening 11 takes place by means of the compensation store created by the excess and with the formation of at least one compensation element therefrom in substantially complete coverage of the opening 11.

In the exemplary embodiment in FIG. 1, viewed in the pull-out direction of the curtain 16, a compensating element

23 in one, here the lower, end-side curtain area and at least one second compensating element 24 in the other, here upper, end-side curtain area, in addition to or instead of this also between these two end-side curtain areas a compensating element 25 can be formed from the compensating memory, which of the Contour and / or size of the opening 11 depends in detail. In order to illustrate this in FIG. 1, there are therefore a total of three such compensation elements 23 in the curtain 16 there,

24 and 25 are shown, of which the compensating element

25 has formed approximately in the middle of the curtain 16. The lower compensating element 23 is formed as a fan with fanning out of some curtain sections 17 on the right side in FIG. 1 and stratification of these curtain sections 17 fanned out on the left side in FIG. 1. In the upper compensating element 24, the fanning out is on the left side in FIG. 1 and the layering on the right side in FIG. 1 of these upper curtain sections 17. How many curtain sections 17 are used for the formation of the respective compensating elements 23 to 25, results essentially from the contour and / or size of the opening 11 to which the curtain 16 is adapted with its edges. The greater the obtuse angle between the retaining strip 19 and the edge of the curtain 21, the greater the number of curtain sections 17 ', 17, 17 "which are required to form the associated compensating element 23, 25, 24.

The layering of some curtain sections 17 at one end of the compensating element 23 and / or 24 can e.g. on this side of the curtain 16 solely by means of self-assembling or by specific holding together of the curtain sections 17 in these end curtain areas. A targeted holding together of some curtain sections to form such layers can e.g. by gluing or e.g. by means of fastening means holding together, such as screws, eyelets, rings, loops or the like.

The holder 20 and / or the holding strip 19 can be detachably attachable in the region of the respective edge 14 or 12 or frame part of the opening 11. For this purpose, effective holding means 26, 27, for example in the form of magnetic holders, which are only indicated schematically in FIG. 1, can be provided for the holder 20 between the holder 20 and the edge 14. In another exemplary embodiment, not shown, the holding means of the holder 20 can also be formed from drivers of the holder 20, which can be brought into engagement with an associated upper edge of a disk which can be moved up and down in approximately vertical direction in FIG. 1 and which open the opening 11 closes in the raised state. Here is in particular thought of window panes that can be moved up and down by electrical actuation, for example in motor vehicles. If one assumes such a starting position of the missile device 10, in which it is in its folded release position, in which the curtain 16 is folded and, for example, is accommodated together with the holder 20 within the holding bar 19, the covering position of the Curtains are produced by first moving the disc down in the opening 11 and then the holding means 26, 27 in the form of

Carriers activated in this way, e.g. are extended so that they can be grasped from the upper edge of the disc. The disc is then raised, whereby, by attacking the holder 20, the closure device 10 is simultaneously pulled out and brought into its covering position, which is achieved when the disc has reached its upper position, in which the disc closes the opening 11.

The holding bar 19 has e.g. an upwardly open U-profile at least on the side facing the curtain 16, so that the retaining strip 19 can thereby serve to accommodate the folded curtain 16 and, depending on the circumstances, also the holder 20.

In the first exemplary embodiment, the holder 20 running on the upper side of the curtain 16 in FIG. 1 is approximately strip-shaped. The holder 20 can be deformably adaptable to the shape and the contour of the associated edge 14. Depending on the course and shape of one or more of the edges 13, 14 and 15, the holder can have a shape that deviates from the linear course, at least on its side facing away from the curtain 16, as will be explained later.

In the embodiment according to FIG. 1, the curtain 16 in the fully extended state has an at least substantially trapezoidal edge contour, in which the right edge 22nd 1 is correspondingly arcuate. In particular, the curtain 16 is dimensioned in accordance with the first embodiment such that in the fully extended state it has the shape of, for example, a rectangle with an arch part located on one side of the rectangle, namely in FIG. 1 5 on the right side of this. If, for example, the curtain 16 according to FIG. 1 is pulled up completely beyond its cover position shown, the upper compensating element 24 becomes an essentially rectangular part. If you refer to this in the whole

10 curtain 16, then including this upper part, the curtain 16 has approximately rectangular shape formed by the left edge 21 and the e.g. horizontally running upper edge approximately at the curtain section 17 ″ there, which is approximately as long as the edge 14, with corresponding opposite

15 can continue the horizontal sides of the curtain, to which then in Fig. 1 on the right the sheet-like arch part adjoins, which is defined by the arched edge 22 and below by about half the length of the curtain section 17 'there.

20th

The closure device 10 has at least one guide device 30 of the curtain 16, which can be pulled out with the curtain 16 when it is pulled open into the cover position according to FIG. 1 and when it moves back into the not

25 shown release position can be moved back. In the exemplary embodiment in FIG. 1, the closure device 10 is provided with a total of three such guide devices 30, 30 'and 30' '. These guide devices have a linear guide 31, 31 ', 31' ', e.g. a tensioning element, on that

30. is displaceable relative to the curtain 16 and on which the curtain 16 is guided with guide parts on the curtain side. These guide parts of the curtain 16 exist here e.g. from openings not shown in the individual curtain sections 17, 17 ', 17' 'through which the associated linear guide extends

35 31, 31 ', 31 *', e.g. the tensioning element, extends through it.

1 shows that, for example, the two guide devices 30, 30 ', in particular their linear guide 31, 31', At least about extend to the axes 18 of the Behangsektionen 17 rather ^¬ angled, wherein the angle formed by the linear guides 31 and 31 include 'with axes 18 to the left in Fig. 1 side, starting from the retaining strip 19 up to the holder 20 about fluctuates by a value of 90 °. The other

Guide ^device 30 ", in particular linear guide 31", runs obliquely with ^respect to these axes 18, the linear guide 31 "on the left in FIG. 1 being at an acute angle to the axes 18 and in FIG. 1 to the right of this an obtuse angle results. The linear guides 31, 31 ″ run approximately parallel to the left edge 13.

The at least one guide device 30, 30 ', 30' 'extends from the holding bar 19 to the holder 20 and engages both. The at least one linear guide 31, 31 ', 31' 'can be designed to be elastically extendable and automatically contractible, e.g. consist entirely or in part of its length of a rubber band or a heather. In the exemplary embodiment shown, the at least one guide device 30, 30 ', 30' 'has at least one receiving memory 32 or 32' or 32 '', only schematically indicated in FIG. 1, for the respectively assigned linear guide 31 or 31 'or 31' ', from which the linear guide 31 or 31' or 32 '' can be emitted, e.g. removable, and by means of which the linear guide 31, 31 ', 31' 'automatically, e.g. by means of spring force, is recordable and storable. The recording memory 32, 32 ', 32' 'is e.g. from a spring accumulator, for example from a spring roller. Other designs are also within the scope of the invention. The storage memory 32, 32 ', 32' 'is arranged on or, as is indicated schematically in FIG. 1, advantageously in the holding bar 19. Instead of or in addition, an arrangement on the holder 20 is also possible.

If the closure device 10 is in its folded release position as the starting position and is to be brought into its covering position, then the holder 20 is gripped, for example, by motor or by hand, and this together with the curtain 16 and the linear guides 31, 31 ', 31''described by the retaining strip 19 away in Fig. 1 upwards and, for example, pulled obliquely to the left. The linear guide 31, 31 ', 31''is removed from the receiving memory 32, 32', 32 '', for example against spring force, and remains under constant tension, so that reliable guidance of the individual curtain sections 17, 17 ', 17''is ensured. also in the final covering position, in which the

Fix holder 20 at the edge 14 by means of the holding means 26, 27. is cash. If the locking device 10 is to be moved out of this covering position back into its release position, the holding force of the holding means 26, 27 is overcome and the curtain 16 by touching e.g. again moved downward on the holder 20, the curtain sections 17, 17 ′, 17 ″ being folded like an accordion and being received in the holding strip 19. Here, the linear guides 31, 31 ', 31' 'are still clamped, which, due to the receiving memories 32, 32', 32 '', e.g. Spring storage, are under tension and are thus taken up again by the storage memory 32, 32 ', 32' 'when the curtain 16 is moved back. The pulling force can also be sufficient in the fully folded state of the curtain 16 in order to exert such a pulling force on the holder 20 that the individual folded curtain sections 17, 17 ', 17' 'are held together in layers.

When pulling out the curtain 16 from the release position into the covering position according to FIG. 1, the lower compensating element 23 and the upper compensating element 24 are formed automatically by fanning out on one side and layering on the other side, due to the excess of the curtain 16 from the compensating store created therewith , depending on the design, the compensating element 25 can also automatically form in the middle. In this way, the closure device 10 is capable of essentially completely covering the specially shaped opening 11 in the covering position by means of its curtain 16. In the second exemplary embodiment shown in FIGS. 2 and 3, the same reference numerals are used for the parts which correspond to the first exemplary embodiment in FIG. 1, so that reference is made to the description of the first exemplary embodiment.

The opening 11 in the second embodiment differs from that in the first embodiment in that the right, curved edge 15 does not immediately merge into the lower edge 12, but ends at a distance above the edge 12 and a straight line at this end of the curved edge 15 running edge part 33 connects, which can run approximately at right angles to the edge 12. In adaptation to this, the curtain 16 then has a rectilinear edge section 34 at the edge 22 with an arc shape. If one were to completely pull out the oversize curtain 16, this would result in the lower compensating element 23 designed in the covering position being pulled out to a possible rectangular shape with the side dimensions of approximately the edge section 34 and the transverse dimension of approximately the lower blind section 17 '.

A further difference compared to the first exemplary embodiment in that in FIGS. 2 and 3 is that at least the lower compensating element 23 is separated from it by means of a schematically indicated reinforcing element 35 in the border area between the compensating element 23 and the subsequent curtain section 17 which follows. By means of the reinforcing element 35, the formation of the compensating element 23 is at least promoted or, depending on the circumstances, also enforced, in particular if, for example, the reinforcing element 35 is articulated on the retaining strip 19 at the left end in FIG. 2 in the position according to FIG. 2. It goes without saying that in the same way, instead of or additionally, such a reinforcing element 35 can be provided in the upper compensating element 24 in FIG. 2. The reinforcing element 35 consists, for example, of a curtain section which is stiffer in itself, a bracing for the latter, or of a separate reinforcing element, for example in the form of a flat material.

As is further illustrated in the second exemplary embodiment with reference to FIG. 3, specifically with the aid of the upper compensating element 24 that is being formed, the top three curtain sections, for example, which enable the fan shape for the compensating element 24, are held together by means of the at least one oblique linear guide 31 ″ and in such a way that this linear guide 31 ″ runs approximately at a right angle to these uppermost three curtain sections 17, for example essentially parallel to the other linear guide 31 ′. FIG. 3 also shows for this area of the curtain 16 that the latter with the linear guides 31 '31' 16 cooperating guide members, for example, '36''aremade' for guiding the curtain from apertures 36. to multiplex attitude of Behangsektionen 17, he ^¬ drive in this range, the stratification of the fan-shaped compensating element 24 are shown in FIG. 3, the first three openings 36 ', calculated from the holder 20, in such a way that not only the linear guide 31 'but also the oblique linear guide 31 "passes through these openings 36'. The openings 36 'coincide. When the linear guide 31 'is pulled tight, the uppermost three curtain sections 17 are layered in this area of overlapping openings 36', the layering being held together by the linear guide 31 ". The linear guide 31" extends to the lowest of the three upper curtain sections 17 obliquely and at an angle not equal to 90 ° to the axes 18 of the curtain sections 17. Only after the linear guide 31 "has entered the lowermost opening 36 'does the linear guide 31" make a sharp bend and now runs parallel to the linear guide 31'. The sides of the linear guide facing each other form an obtuse angle in the kink area. ^■ Also in the example shown in Fig. 4 for the third embodiment, parts corresponding to the first embodiment, used for the same purpose, the same reference numerals.

In Fig. 4, the opening 11 is designed so that the left side edge 13 is inclined and at an acute angle to the lower edge 12. The right edge 15 runs in a straight line and, like the edge 13, at an angle * 0 of less than 90 ° to the lower edge 12. The upper edge 14 is not as wide as the lower edge 12 and is at least slightly curved upwards.

The curtain 16 is adapted to this contour and size of the opening 11 * 5 with corresponding inclined edges 21 and 22. The closure device 10 here further has two guide devices 30 ″, both of which run at an acute angle to the axes 18 of the curtain sections 17. The respective acute angles are formed between each

20 a linear guide 31 '' and z. B. the lower retaining bar 19, which runs approximately parallel to the axes 18.

The holder 20 has approximately such a length here that the distance between the edges 13 and 15 at the upper end of one

25 other corresponds. The peculiarity of the holder 20 is that it has a shape deviating from the linear profile at least on the side facing away from the curtain 16, here on its upper side, specifically on this upper side being approximately curved in conformity with the curved profile of the Margin 14.

The holder 20 is shorter than the retaining strip 19. Both run essentially non-parallel to each other, and there may also be a certain longitudinal offset between the two. The curtain 16 is in the fully extended state 1 approximately trapezoidal shape and such an oversize to form a compensation memory that in this embodiment, an upper compensation element 24 as a fan with some on the right in Fig. 4 fanning out

° curtain sections and on the other, in Fig. 4 left layering of these curtain sections results.

For all the other exemplary embodiments, the same reference numerals are used for the parts according to FIG. 1 for the reasons mentioned.

In the fourth embodiment in Fig. 5 is the opening

11 approximately parallelogram-shaped, the lower edge

12 and the upper edge 14 can run approximately parallel to one another 5 and can also be of approximately the same size, but have a longitudinal offset to one another. The two lateral edges 13 and 15 can run approximately parallel to one another and be of approximately the same size. The left edge 13 encloses an acute angle with the lower edge 12, while the right edge 15 encloses an obtuse angle with the edge 12.

The curtain 16 of the closure device 10 is also adapted to these dimensions and contours of the opening 11. He has ° z. B. about half the length, viewed in the pull-out direction, and on the lower half, in the fully extended state approximately rectangular shape. The adjoining area of the curtain has curtain sections 17 which run approximately parallel to one another and are articulated about the axes 18. The lower curtain part, which is approximately rectangular in the extended state, has the excess with the formation of a compensating store, in which in FIG shown cover position here results in a lower compensating element 23. This compensating element also forms 5 as compartments with the one on the left in FIG. 5

Fanning out some curtain sections 17 and stratification of these curtain sections 17 on the other side. The closure device 10 has two guide devices 30 and 30 ″ with respective linear guides 31 and 31 ″, of which the guide device 30 with linear guide 31 runs approximately at right angles to the axes 18 of the curtain sections 17 above the compensating element 23, while the other guide device 30 ″ its linear guide 31 "is inclined at an acute angle to it, such that there is an acute angle on the right of the linear guide 31 ' ^{1 and} an obtuse angle on the left. The right edge 22 of the curtain 16 extends to the retaining strip 19 at an obtuse angle at an angle greater than 90 °. The length of the individual curtain sections 17 of the upper curtain part decreases approximately along the edge 14 in FIG. 5 to the right. The curtain sections 17 are thus becoming increasingly shorter in this direction. The holder 20 is here approximately triangular, whereby it fits in the right corner area formed between the edges 14 and 15. The curtain 16 is approximately trapezoidal in the fully extended state.

In the fifth exemplary embodiment shown in FIG. 6, the curtain 16, in adaptation to the contour and size of the opening 11 in the fully extended state, has an edge contour which corresponds at least approximately to a semi-ellipse. The holder 20 is located on the left-hand end curtain region in FIG. 6, while the retaining strip 19 engages on the right-hand end curtain region, the holding strip 19 being dimensioned considerably longer than the holder 20 and at

Half ellipse represents approximately the shorter ellipse half axis when the curtain 16 is fully extended. It can be seen that the holder 20 and the retaining strip 19 run non-parallel relative to one another and some curtain sections 17 with their axes 18 run approximately parallel to one another on the curtain side in the covering position shown. Due to the overhang on the curtain side between the holder 20 and the holding bar 19, a curtain-side compensating memory results in FIG. 6 on the right, from which, in the covering position shown, a compensating element 23 is formed as a fan adjacent to the holding bar 19 by fanning out at the upper edge region in FIG. 6 some curtain sections and by layering these curtain sections on the other side, the stratification occurs at the lower end of the holding strip 19 in FIG. 6.

The locking device 10 has, analogously to that in FIG. 4, two oblique guide devices 30 ″ with oblique linear guides 31 ″, both of which run at an acute angle to the approximately parallel axes 18 of the curtain sections 17, the upper linear guide 31 ″ being an acute angle smaller than 90 ° and the lower linear guide 31 '' form an obtuse angle greater than 90 ° with the retaining strip 19. The holder 20 has, at least on the side facing away from the curtain 16, a shape deviating from the linear profile, here an arc shape.

In the sixth exemplary embodiment shown in FIG. 7, the opening 11 and, in adaptation thereto, the curtain 16 have approximately the shape of a symmetrical half of a semi-ellipse, only half of the shorter semiaxis of which is present, along which the retaining strip 19 lies when the curtain 16 is fully extended runs. The edge 15 of the opening 11 on the right in FIG. 7 and, in an adaptation thereto, the edge 22 of the curtain 16 running there in the covering position run obliquely and at an obtuse angle to the retaining strip 19 with which these edges 15 and 22 enclose an angle greater than 90 °. The opposite edge 13 of the opening 11 and 21 of the curtain 16 has an essentially arch shape, the arch extending from the lower edge 12 to the upper end of the edges 15, 22. In the corner position shown, the holder 20 is located in this corner area, which is designed to be essentially triangular in adaptation to the corner. Two guide devices 30/30 "extend between the holder 20 and the holding strip 19. The linear guide 31 of the guide 30 runs approximately at right angles to the axes 18 of individual mutually parallel curtain sections 17 and thereby obliquely at an obtuse angle that is greater than 90 ° to the retaining strip 19. The other guide device 30 "with its linear guide 31" extends obliquely to the curtain sections 17 and at an acute angle, including an angle of less than 90 ° between the Linear guide 31 "with its side facing the retaining bar 19 and the retaining bar 19. The excess of

Curtain 16 enables the formation of a lower compensating element 23 adjoining the holding bar 19 by fanning out some hanging sections at the edge 21 and by layering these hanging sections on the other edge 22, for example at the right end region of the holding bar 19.

In the seventh exemplary embodiment shown in FIG. 8, the holding strip 19 runs on the left edge 13 of the opening 11 and the holder 20 at a distance to the right thereof, which is likewise approximately triangular here. The shape of the curtain 16 in the fully extended state corresponds approximately to that of the sixth exemplary embodiment in FIG. 7. This also applies to the two guide devices 30, 30 "with linear guides 31, 31". Overall, the closure device 10 in FIG. 8 is similar to that in FIG. 7, whereby it is only placed differently in the room to match the opening 11.

In the eighth exemplary embodiment of the closure device 10 shown in the covering position in FIG. 9, the opening 11 has approximately the contour of that in FIG. 1 with a lower edge 12, left edge 13, which extends obliquely to the edge 12 to form an obtuse angle, an upper edge 14, the z. B. can run approximately parallel to the edge 12, but in comparison is dimensioned much shorter, and an arcuate edge 15 located on the right. In contrast to FIG. 1, in FIG. 9, however, the pull-out direction of the curtain 16 runs horizontally, for. B. in Fig. 9 from left to right. The individual curtain sections 17, and a substantial part of them, including their axes 18 run essentially at right angles to the edge 12, 22. In the covering position shown in FIG. 9, the retaining bar 19 runs obliquely and approximately parallel to the edge 13, the retaining bar 19 including an obtuse angle greater than 90 ° with the lower edge 22 of the curtain 16. The holder 20 acting on the curtain 16 on the right in FIG. 9 runs parallel to the holding strip 19 and can have a relative longitudinal offset. The holder 20 is designed to match the arcuate edge 15 on its upper side in an arc shape, where holding means 26 and 27 are indicated.

The closure device 10 has two guide devices 30 and 30 "with respective linear guides 31 and 31", respectively, which run between the holder 20 and the holding strip 19. One linear guide 31 runs approximately parallel to the edge 12, 22 and approximately at right angles to the axes 18 and most of the curtain sections 17, while the other linear guide 31 ″ runs obliquely with respect to the retaining bar 19 and the axes 18 and curtain sections 17, in this way 9, most of the curtain sections 17 run approximately vertically, and here too the curtain 16 has an excess over its length between the retaining bar 19 and the holder 20 as a compensation store Formation of at least one compensating element, with compensating elements 23 and 24 respectively forming in the covering position shown on the left and right end region of the curtain in Fig. 9. The compensating element 23 is formed by fanning out some curtain sections

17 on the upper edge region 21 in FIG. 9 and by layering on the lower edge region 22 in FIG. 9 and at the end of the holding strip 19 there. The other compensating element 24 is formed in the region of the holder 20 by fanning out on the lower edge 22 of the curtain 16 and 16 there by layering the corresponding curtain sections at the upper end of the holder 20 in FIG. 9.

In the area of the upper edge 14 is a receiving strip 40 z. B. releasably attached, which has in cross section approximately U-profile with the U opening directed downward. The recording bar 40 can be detachably attached, for example, to a frame part running along the edge 14 or to another edge of the opening 11. On this receiving bar 40, the holding bar 19 together with the curtain 16, which can be accommodated therein in the folded state (FIG. 10), is held with one end, namely with the end located at the top in FIG. 9, about the axis 41. In this way, when the closing device 10 is brought into its release position relative to the holding bar 19 and received in the latter, the holding bar 19 together with the closing device can be inserted into the

Receiving bar 40 can be folded in, as shown in Fig. 10. Conversely, in this way the retaining bar 19 and together with this the entire closure device 10 can be folded out about the axis 41 from the receiving bar 40 into the functional position shown in FIG. 9, in which the curtain 16 can then be pulled out as far as described, until the cover position shown in FIG. 9 for the opening 11 is reached.

9 and 10 schematically indicate that the receiving bar 40 near the pivot axis 41 of the holding bar 19 has at least one securing element 42, by means of which the holding bar 19 pivoted out of the receiving bar 40 can be secured in the pivoted-out state (FIG. 9).

The receiving bar 40 is preferably at a distance from the pivot axis 41, for. B. at the right in FIGS. 9 and 10 end region, at least one schematically indicated locking element 43, z. B. in the form of a magnet, by means of which the holding bar 19 received in the holding bar 40

(Fig. 10) can be locked on the receiving bar 40, so that this non-functional position is secured according to FIG. 10. If the closure device 10 is to be brought into its functional position, the detent of the holding bar 19 is brought about from the receiving bar 14 in the latching element 43 and then the holding bar 19 together with the whole locking device 10 in it and pivoted about the axis 41 in Fig. 10 clockwise and towards the edge 13 until the locking element 42 engages in the end position shown in Fig. 9 and secures this position of the retaining bar 19. Then z. B. by touching the holder 20 of the curtain 16 in FIG. 9 approximately in the horizontal direction into the covering position together with the guide devices 30, 30 ", the receiving strip 40 for the edge region 21 of the curtain 16" which runs along the upper edge 14 , can at the same time form a reception and a guide.

In an advantageous embodiment of the invention, the curtain sections in the extended covering state of the closure device extend at least in the area of a curtain edge and thereby in the direction of the axes of the curtain sections beyond the surface area which passes through the holding strip, the holder and the two connecting lines between adjacent end points of the holding strip and holder is formed.

In FIG. 2, the holding strip 19 has a left end point 46 and a right end point 47. The holder 20 has a left end point 44 and a right end point 45. The aforementioned connecting line 49 extends from the right end point 45 of the holder 20 to the right end point 47 of the holding bar 19. The aforementioned connecting line 50 extends from the left end point 44 of the holder 20 to the left end point 46 of the holding bar 19.

A folding curtain is described for utility model 89 09 836.6. In this case, the distance between an oblique edge (there 3, 4) and the adjacent linear guide (there 18a, 18c) is a maximum of one to two centimeters, which can be described as the cantilever length of the curtain. The Krag ^¬ length of individual Behangsektionen over the entire Behangbereich is only a fraction of the run length of individual Curtain sections. In contrast, in the closure device according to the invention, the cantilever length of individual curtain sections is at least in individual curtain areas and at least in the area of a free curtain edge, the same size or only insignificantly smaller than the guided area of these curtain sections. The cantilever length of individual curtain sections, particularly in the area of inclined and / or curved curtain edges, is quite large in comparison to the guided length of these curtain sections. The guided area of a curtain section is the area that extends between two linear guides.

In a further advantageous embodiment of the invention, the contour of the surface piece, which enclose the two outer linear guides with retaining strip and holder, is not identical to the contour of the curtain in the extended state of the closure device. The contour of the curtain deviates from the course of the associated linear guide and thus from the contour of the aforementioned surface piece, at least in the region of one and thereby the curved, partially curved or curved straight curtain edge. The arch-shaped, partially arch-shaped or arch-straight curtain edge deviates from the course of the assigned linear guide over at least part or even over its entire curtain edge length and thus runs non-parallel to it. Also the other roughly straight curtain edge, shown as the left curtain edge e.g. in Fig. 2, deviates in the region of its compensating part associated with the holder from the straight course and runs there approximately slightly arcuate. This curtain edge also deviates at least over a small, upper area in the extended state of the curtain from the straight course of the adjacent, assigned linear guide.

In a further advantageous embodiment of the invention, the curtain sections which are assigned to the compensating part on the retaining bar are all of the same length. In another embodiment, the curtain sections are this Compensating part starting from the holding bar towards the holder evenly or even unevenly shorter. The maximum length of a curtain section is equal to the length of the retaining bar. In one embodiment, all curtain sections have the same length in the curtain area between the compensating part on the holding bar and the compensating part on the holder. In another embodiment, these curtain sections are evenly or unevenly shorter in the direction of the holder.

In a further advantageous embodiment, the curtain sections which are assigned to the compensating element on the holder are all of approximately the same length. In another embodiment, these curtain sections become longer or longer, starting from the holder towards the holding bar.

In a further, but not shown, advantageous embodiment, the linear guides 31 ″ in FIG. 4 run at right angles to the holding bar 19.

In a further embodiment, not shown, the holder 20 is e.g. 2 shorter than the assigned edge 14. The length of the holder 20 can be three quarters, half or even just a quarter of the length of the assigned edge 14.

In a further advantageous embodiment, the receiving strip 40 is not arranged on the upper edge 14 of the opening 11, as shown in FIG. 9, but on the lower edge 12. The retaining bar 19 is folded out in the counterclockwise direction into the position shown in FIG. 9 and fixed there. In a further advantageous embodiment, the

Openings 36 ′ and / or 36 ″ are designed as elongated holes, the long axis of the respective elongated hole running approximately parallel to the axis 18 of the curtain sections 17. The design of the openings 36 'and / or 36' 'as elongated holes, in particular in the area of the fan-like compensating elements, guarantees that individual curtain sections are not clamped between the linear guides or between a linear guide and the holder and warp. This guarantees the full freedom of movement of each linear guide over the entire area of the curtain.

In a further advantageous embodiment, the holder and / or the holding strip can be curved and can be adapted to the curved contour of the assigned window edge. A design of the retaining strip in the form of an arc is possible because the curtain has enough flexibility both in the stacked state and in the extended covering position to adapt to the curved edge.

If one considers the curtain 16 in FIG. 1, it can easily be seen that the curtain sections 17 'are layered on the left curtain edge 21 and there in the area of the compensating element 23. Thereafter, in the area of the curtain edge 21 there is a large area of fanned out curtain sections 17, which is followed by a small area of layered curtain sections 17. The two aforementioned areas consisting of curtain sections 17 both belong to the compensating element 25. The aforementioned small area of layered curtain sections 17 is followed by the compensating element 24 with a curtain sections 17 ″ also fanned out in a small area. On the right, curved curtain edge 22 of the curtain 16 are in the area of the compensation 23 the individual curtain sections 17 'fanned out.

This area of fanned curtain sections 17 'is adjoined at the top by an area of layered curtain sections 17, which already belongs to the compensating element 25. A further area of fanned curtain sections 17, which also still belongs to the compensating element 25, adjoins these curtain sections 17. It follows that the compensation element 25 consists of two fan-like compensation areas. Going further up, there is an area of closely layered curtain sections 17 ″, which belongs to the compensating element 24. Thus, the curtain 16 in FIG. 1 consists of three compensating elements 23, 24, 25, but the compensating element 25 is formed from two compensating areas. Compensation element 23 and 24 each have only one compensation area. The curtain 16 thus consists of four different compensation areas which are arranged with respect to one another in such a way that continuously stratified and fanned areas follow one another at each edge 21 and 22 of the curtain 16. If one considers each edge 21 and 22 of the curtain 16 in isolation, continuously stratified and fanned areas alternate along these edge edges 21, 22. If both edge edges are considered at the same time, it is found that a layered area of edge edge 21 is assigned a fanned-out area of edge edge 22 and a fanned-out area of edge edge 21 is a visible area of edge edge 22. The fan-like compensating areas of the compensating elements 23, 24, 25 are thus essentially arranged in the area of the curtain in the covering position, as B. triangular cake pieces on a rectangular tray to save space.

If the compensating element 25 is replaced in FIG. 1 by an association of essentially parallel curtain sections 17, the law of the alternate occurrence of layered and fanned curtain areas still applies along the same edge. The parallel bond between the compensating elements 23 and 24 acts as an absolutely neutral area.

If the curtain of the closure device is in the fully extended state, all adjacent curtain sections enclose approximately the same angle with one another. The oversize of the curtain is defined as the curtain surface which arises when the surface of the opening which the curtain of this closure device covers in the cover position thereof is subtracted from the cover surface of a closure device in the fully extended state of the curtain.

If a closure device e.g. as configured in FIG. 2, this consists of an upper and a lower compensating element and a parallel assembly of curtain sections arranged between the two compensating elements. This configuration brings optical advantages above all because it enables a uniform distribution of the curtain sections over the entire area of the curtain.

In further advantageous embodiments, the curtain 16 in Fig.l, Fig.2, Fig.4, Fig.5 can be arranged so that the curtain sections - as in Fig.9 - essentially perpendicular to the edge 12 of the respective

Opening 11 run. In the cover position of the closure device 10, the retaining strip 19 is assigned to the lateral edge 13 (Flg.l, Fig.2) or edge 15 (Fig. 4). In FIG. 5, the holding strip 19 can be assigned to both the edge 13 and the edge 15 in the covering position of the closure device 10.

In an advantageous embodiment, the curtain sections in the vertical cross section are honeycomb-like

Formed parts that can be folded into a stack of packages. In Fig. 2, a closure device 10 is shown in the cover position thereof. If this closure device is brought into its release position (storage position), the holder 20 lies on a stack of folded curtain sections 17 ″, 17 and 17 ^* . This stack of folded curtain sections is in turn on the holding bar 19. The end point 46 of the holding bar 19 and the end point 44 of the holder 20 lie directly one above the other. Now you set up a vertical line on the retaining bar 19, which goes through the end point 46 and extends up to the edge 14 of the opening 11. It is found that the end point 44 of the holder 20 lies on this vertical. If the curtain 16 is now brought into its covering position and the holder 20 is in its uppermost position shown in FIG. 2, it can be seen that the end point 44 of the holder 20 is at a longitudinal distance from the said vertical. This longitudinal distance of the end point 44 of the holder 20 from the vertical through the end point 46 of the retaining strip 19 is called the longitudinal offset.

The linear guides also run in a straight line in the area of the compensating part and thus also in the fanned area. In the covering position of the closure device, the linear guides can run perpendicular to the associated holding strip 19.

At least one of the existing linear guides runs at an angle unequal to 90 degrees to the holder in the covering position of the locking device. The angle mentioned can deviate considerably from 90 degrees.

In the covering position of the closure device, at least one linear guide preferably runs at an angle unequal to 90 degrees to the retaining strip. The angle mentioned can deviate considerably from 90 degrees.
