Abstract

On large window and door openings frequently made today, the manufacturers of venetian blinds in particular cannot cover the whole opening with just one blind. Therefore, it is necessary to arrange two or more hangings. However, these must be guided on both sides, and therefore a lateral guide between the two jambs of the opening is necessary. Such a guide is, however, undesirable for aesthetic reasons. According to the invention a temporary guide is created for the edges which need not be guided in the jambs and does this by means of a guide arrangement which can be accommodated rolled-up above the elevating device and can be introduced into the door or window opening.

Description

Guide arrangement for a curtain

The invention relates to a guide arrangement for a curtain, such as a store or awning, according to

Preamble of claim 1.

Guide arrangements serve the vertical lateral

Guiding of hangings, in particular slat blinds and awnings. The guide rails give the curtain a lateral guidance and a definitive grip and

prevent a movement of the curtain in horizontal

Direction in gusts of wind. Each curtain is usually guided by two guide rails which are attached laterally to the soffits of windows or doors of the building.

For some years, door and window openings have been made larger and often designed as huge sliding windows. This results in openings of a width of several meters and thus exceed the maximum of the Storenherstellern available blind widths. To still a slat blind or a vertical awning, too

200123WO 10.10.2013 Before attaching such large openings, it is necessary to set up between the two lateral soffits of the window one or more columns with guide rails arranged in the clear cross-section of the opening. This is for aesthetic reasons

undesirable, because the clear view, which is ensured by the modern sliding windows, through

Guide rail columns is impaired.

It is also known that in fixed glazing the

Slats are supported and guided in the middle by a fixed fixed wire at the top and bottom.

An object of the present invention is to provide a temporary guide arrangement, which in each case two adjacent hangings, which are guided on one side of fixed guides, to guide in the lowered state on the second side and in raised hangings the second temporary guide again out of the field of vision, that is, from the light

Opening of the window or door disappear.

This object is achieved by a guide arrangement according to the features of claim 1. Advantageous embodiments of the guide arrangement are described in the dependent claims. With the help of elongated linear guide forming body, either from above vertically down into the door or window opening retract or on the one hand can be deflected by a diverter and on the other hand are rigid in the extended or tensioned position, can be a guide before or during lowering of

Create hangings and also remove them from the field of vision once the hangings have been raised.

With the use of two link chains, which are arranged lying for example on the elevator device and deflected to form a temporary guide down and hooked together during the deflection, a stable, in particular rigid guide can be created. In a preferred embodiment, the front, that is to say the lower end of the two joined together

Link chains with one at the bottom of the door or

Window opening arranged holding and catching device, which a lateral pivoting away the stiff

Guide rail in the floor area prevents, if depending on wind conditions, larger forces on the

hang down hanging hangings. In strong gusts of wind, the lowering and forming of the new temporary

Guiding before lowering the blind, so that only the guide is exposed to any wind forces.

In a further advantageous embodiment of

Invention occurs in place of a link chain in

Hibernation essentially an arcuate Cross-section steel strip, which is also stored above the Aufziefersvorrichtung and when descending leading unites with a second mirror-image arranged band and has a high rigidity by the thus formed tubular hollow body. The two bands are held securely in any position by guide sliders attached to the ends of the two adjacent edges of the blinds.

In a further cost-effective embodiment, a wire rope or a band is guided vertically downwards before lowering or in calm, together with the lowering of the curtain, and the lower end of which is guided at one

corresponding holding and clamping device, for example, a slot or eyelet hooked. By slightly pulling back, that is, pulling the rope upwards, it can be stretched and thus likewise forms a temporary guide in the center of the window or door opening. Of course, the tensioning can also be done by moving the holding and tensioning device downwards. For door openings that have a width that requires more than two hangings, the central

arranged hangings are guided on both sides of temporary guides according to the invention. With reference to three illustrated embodiments, the invention will be explained in more detail. Show it: Figure 1 with a window or door opening

In the first embodiment according to Figures 1 to 6 is a curtain in front view, for example a

Slat blinds indicated by reference numeral 1. At

Elevator belts 3 hangs a disk pack 5 comprising a plurality of fins 5a. The lamellae 5a or the lamella packet 5 is suspended with its elevator belts 3 on an elevator device 7, which is shown in the figures with a rectangle. In the elevator apparatus of conventional construction, the elevator elements are for

Winding and unwinding of the elevator belts 3, the Drive elements and the drives for turning tapes 4 housed. The box-shaped elevator device 7 is arranged in the fall (not shown) of a window opening or door opening 11 in a wall 9.

The elevator device may also be mounted above the window or door opening on the facade.

At the lateral soffits of the opening 11 or the outside of the facade guide rails 13 are fixed, in which the slats 5a and at the ends thereof

attached guide elements or pins (not

shown) are guided in a vertical slot. The fins 5a, the guide elements or pins and the guide rails 13 are known from the prior art in many designs. The two hangings 1a and 1b are thus guided by the guide rails 13 on one side at the ends of the slats 5a. The two adjacent sides of the two hangings 1a, 1b, which lie in the middle of an opening 11, are not guided in fixed guide rails, but according to the invention, in a guide arrangement, as in the enlarged view A in Figure 3

is shown in sections. This guide assembly 15 forms a temporary guide, which is constructed before or during the lowering of the slats 5a and the

Pulling up the fins 5a or thereafter to expose the opening 11 in the wall 9 is removed again. The

Guide assembly 15 includes two elongate ones in one In the first exemplary embodiment according to FIGS. 1 to 6, the elements 17 comprise a cross-sectionally curved elastic metal or plastic strip, which is guided above the elevator device 7 either parallel to it or on a core (not shown) is wound up. In the stretched form are the

Elements 17 in relation to their cross section rigid and can be easily deflected by a deflection roller 19 by 90 °. Such pulleys 19 are at the two opposite ends of

Elevator devices 7 are arranged and guide the elements 19 from the horizontal position to a vertical position.

Alternatively, in front of the pulleys 19 guide and

Press rollers 21 may be arranged, with which the initially arcuate elements 17 are flattened to abut when entwining the guide rollers 19 thereto. After the deflection by 90 ° reach the band-shaped elements 17 along the edges 17a in mutual contact.

This contact is supported by a

Guide sleeve 23. The now fed with their edges 17a adjacent elements 17 penetrate the

Guide sleeve 23. Below the guide sleeve 23 guide slide 25 are arranged, on which the fins 5a are hinged on both sides. Hinged means: The slats 5a can through the turning tapes 4 and Elevator belts 3 are pivoted in a conventional manner. The passage opening in the guide slides 25 are dimensioned such that the guide slides 25 with low friction, preferably approximately frictionless, along the two now combined into a hollow body band-shaped elements 17 can slide.

Of course, the rigid ones too

Guide rails 13 are replaced by flexible temporary elements 17.

Below is briefly the operation of the first

Embodiment of the invention explained.

Starting from a raised curtain 1, in which the fins 5a are superimposed on each other and a

Disc set 5 form (see black area in Figure 1) is lowered in a known manner by unwinding the elevator belts 3, the plate pack 5 successively and the

second-highest lamella 5a dissolves from the uppermost

lying until a gap between the two slats arises, which is determined by the distance between the fastening elements 27 on the turning belts 4, arises. Synchronous to the lowering movement of the elevator belts 3, the two band-shaped elements 17 via the pulleys 19th

deflected and fed together in the guide sleeve 23 and thus continuously form a rigid temporary tubular vertical guide 29th Preferably, at the lower end of the vertical guide, ie at the two free but mutually rigidly connected ends of the elements 17, a conical tip 31 or the like arranged, which in a specific recess 33 as anchoring to the lower edge of

Window opening 11 or can engage the ground to stabilize the vertical guide down and hold.

The drives for the elevator belts 3 in the two

Curtains la and lb and the drives for the two elongated elements 17 are preferably

synchronized, if necessary, the drives for the elements 17 can run slightly faster or faster, so that the temporary vertical guide 29 with its tip 31 the

Recess 33 reached before the curtain 1 completely

is extended. Of course, the temporary vertical guide 29 is already completely down

be extended before the curtain 1 is lowered. This variant ensures that even at unfavorable

Wind conditions of the curtain 1 safely and vertically down can be driven.

In the second exemplary embodiment according to FIGS. 7 to 10, two link chains 117, for example pusher link chains, which are mounted above the elevator device 7, take the place of bands bent in cross section. In a guide sleeve 123, the link chains 117, after passing over pulleys (pulleys not

shown) are deflected in the guide sleeve 123 down and united, to a vertical guide 129th

transformed. Link chains 117, which in one

Guide sleeve 123 are hooked together, are known in the art as a replacement for lifting devices and are not described in detail. A well-known link chain, by union with a second to a stiff one

Element is shaped, is known under the name Zip chain. In order that the link chains 117 are capable of guiding the ends of louvers 105a, guide rail elements 125 are attached laterally thereon respectively to the chain links, which join together after the union of the two link chains 117 to form a continuous vertical guide 129 for the lamellae 5a. In the slots of the guide rail elements 23, the guide pins on the slats 5a are guided laterally and can move freely in the vertical. The following is the operation of the second

Embodiment explained. Synchronously with the lowering of the plate pack 5 or more or less flow, the link chains 117 are connected in the guide sleeve 123 together and slide as a rigid

Vertical guide 129 vertically downwards. The fins 5a, laterally guided in the guide rail elements 125 on the chain links 117 also travel down and take their spaced position with respect to the vertical.

As in the first embodiment, a mandrel or the like may also be attached here at the lower end of the united link chains 117, which is held centered in a recess in the bottom of the window or door opening.

The third embodiment according to Figures 11 to 14 differs from the second in that the

Guide rail elements 125 not laterally to the

Chain links are attached, but between the individual chain links (see Figure 14). To the mass of the lowered link chain 117th

can compensate, at its upper end a spring 137 or a rubber band to be attached, the second end is connected to the elevator device 7. Of course, the two adjacent hangings 1, which are guided by the guide arrangement, not adjacent to each other in a plane, but they can be arranged at any angle, be it now in a corner of 90 ° or more or less degrees.

In Figures 15 to 22 is another aesthetically sophisticated embodiment of the invention in two Illustrations shown. Instead of a link chain or other stiffening guide member enters a cable or a rope 217, which is stored in the Aufzubugsvorrichtung 7, for example, wound up and can be lowered together with the curtain 1 or can run this. At the lower end of the cable 217 or at the bottom of an anchoring device, for example a magnet 231 is arranged and recessed preferably recessed in the ground, which adheres to the lower boundary 239 of the opening 11 in the wall or on which device the cable is held, as soon as the cable 217 is lowered.

In FIG. 23, a first embodiment of a

Device 241 shown, with which the magnets 231 can be held at the lower end of the cable 217 after lowering and tensioned. In FIG. 23, the

Device 241 by a cover 243, which is flush with the floor, closed. In order for the lid 243 can be opened, 245 are attached to this slots.

In the opened state according to FIG. 24 it can be seen that at the upper cover 247 at right angles to the

Slots 245 on the lid 243 extending second slots 249 are formed. On the two side walls of the

Device 241 are formed below the second slots 249 recesses 251, which are intended to insert the cable 217 with the attached magnets or metal parts 231 in the device 241. In the device 241 are suitably trained

Fanghooks or tabs (not shown) arranged, which take the magnets 231 or metal parts and with a tensioning device, of which only a tensioning shaft 252 is visible pull the cables 217 down and tighten. Alternatively, the top cover 247 of the

Clamping device 241 are lowered and pull the voltage applied to the underside of magnets 231 down. As an alternative to a shaft 253 to be rotated by hand with a corresponding key as a tensioning element, an electrically operated tensioning device can also be used in the device 241. In a particularly advantageous embodiment of the device 241 for

Clamping the cables 217 may also be further used a sensor (not shown), which triggers the clamping in the presence of the magnets 231 in the clamping device 241, so that the command for clamping must not be done manually.

In a further advantageous embodiment of

Clamping device 241 may be formed in the lid 243 and in the top cover 247 a funnel-shaped opening into which the magnet 231 is inevitably inserted when lowering the cable 217, so that the tensioning of the cable 231 is automatically made as soon as cable 231 reaches the lower end to have. As a trigger for the Lowering the cable 231 is done by the command, the

Disturbing or awning, i. the curtain 1, is lowered.

FIG. 25 shows schematically a take-up drum 255 for the cable 217. On the cable 217, a compression sleeve 257 is applied, which at the end of

Lowering of the cable 217 in a clamping pot 259, in which a tension spring 261 is housed, enters. On the upper end of the spring 261 sits a switching tab 263, which is pressed by the compression sleeve 257 down when the cables 217 are tensioned in the tensioning device 241. As soon as the voltage has built up completely, the switching tab 263 releases from a switch 265. From the switch 265, a signal is sent to the control of the curtain 1 so that the hanging 1 can be lowered. As long as the switching tab 263 out of contact with the

Switch 265, the curtain 1 can open and

be driven down. In a further embodiment of the

Monitoring device according to Figures 28 and 29, the shaft of the winding drum 371 for the rope 317 is mounted on a rocker 373, which is pivotable about a fixed pivot point 375 on the housing of the elevator device 7. The rocker 373 can either be on one side or

be arranged on both sides of the take-up drum 355. The pivot point 375 opposite end of the rocker 373 hangs on a tension spring 377, which is attached fixed above above and at the bottom of a bolt 379 on the rocker 373th

attacks. In an untensioned condition, as shown in FIG. 28, a tab 381 extending horizontally away from the rocker 373 does not touch a switching element 383 or its axially displaceable switching button 385. However, once the rope 317 is stretched in the direction of the arrow P, that is, when the lower end of the rope 317 in the device 241 for tensioning the rope 317 pulled taut, the rocker 373 is in

Turned counterclockwise and the tab 381 is pressed against the switch button 385 and pushes it in

Switching element 383 upwards. Once this is done, the controller recognizes (not shown) that the

Vertical guide for the blind (store or awning) is ready to lower the curtain down and to guide laterally in the lowered position.

As soon as the curtain has been raised again by the operator and thus the window or

Door is no longer swept by a curtain, the rope from the device 241 for tensioning the rope 317 can be dissolved out again and is wound up by a built-in winding drum 371 spring back on the winding drum 355. A braking element (not shown) in the winding drum 355 causes the pulling up of the rope 17 is slow and whose lower end can not be thrown uncontrollably with the magnetic or metal support member.

In FIGS. 26 and 27, the housings of FIGS

Take-up drum 255 can be seen and their arrangement laterally or above the elevator device 7. In Figure 26, which shows the elevator device for a vertical awning, is clearly visible as the cable 217 through

End pieces 267 are guided on a end rail 269 on the curtain 1.

In FIG. 27, the cables 217 preferably extend in suitably arranged openings 271 in the edge regions of the lamellae of the lamella packet 5. Consequently, there are no additional lugs protruding beyond the ends of the lamellae

Guide pins or the like necessary, as they are common in de guide in lateral rigid guide rails. Down-driving, i. the unwinding of the cable 217 is carried out in the basic version by pulling down the cable 217 to the magnet 231 or magnetizable metal elements, for example, with a arranged at the end of a rod magnet (not shown).

Of course it is also possible, the

To drive take-up drum 255 electrically, that is to handle the cable 217 without manual intervention and, if there is a funnel-shaped inlet in the tensioning device 241, allow the cable to run in there and tension by the tensioning device. In another embodiment, not shown, the vertical guide for the slats 5a is formed by a plurality of tube sections lined up on a rope. The pipe sections can, if the rope is not stretched, as the chain links in the second

Embodiment to a deflection roller are guided in the vertical and by tensioning the rope after

Transfer to the vertical position will be the

Pipe sections pressed together so that they form the stiffened guide for the slats 5a.

In a further embodiment of the invention, not shown, the vertical guidance by a

Telescopic tube formed, which enters from above into the light of the door or window opening and are arranged on the guides which guide the ends of the blades 5a of the adjacent hangings 1 (not shown).
