Curtain screen

7Q988A / 100?

The invention relates to a curtain screen for use over windows or passageways.

Curtain shades are commonly used over windows or doors to provide support or fasteners to cover a curtain of a window or a doorway, as the bracket or the fastening devices, e.g. curtain rails or a roller blind, the general aesthetic appearance of this area is detrimental can affect. The curtain screen can be made of fabric or of solid construction, and is generally decorated to enhance their appearance.

In the case of curtains made of either fabric or solid material, the fasteners for the window or Door curtain is first placed over the passage or window. This can be a chore that a requires precise alignment and attachment of a number of brackets, on which, for example, a curtain rail is attached. For the curtain screen, brackets are also required, which are just as elaborately arranged and need to be attached. In the case of a curtain screen made of fabric, this is relatively easy to attach Aperture possible on their holding devices. It is usually difficult to attach fixed curtain panels, as they are long and difficult to handle, and this presents difficulties when an accurate alignment on or is required on the brackets which are fixed at a relatively high point above the passage or window.

The object of the invention is to overcome the disadvantages mentioned above and a quick and easy-to-install curtain screen with window or door curtain holding devices to accomplish.

709884/1007

This object is achieved according to the invention in that a screen for use over a window or a passage is provided which is an elongate member with a generally U-shaped cross-section transverse to the longitudinal direction comprises that holding devices are provided for fastening a cover or a curtain for a work opening and mounted within the generally U-shaped cross-section in the elongate member. The curtain screen is designed so that it can be attached to a wing above the work opening.

The term "curtain" or "covering ¹ } as used in this specification includes draperies, door curtains, hangings, drapes, blinds or sunshades, blinds, shutters or any other possible door or window covering that is either rigid or flexible .

The present invention thus provides a curtain screen which is either a support for a curtain rail, for example or includes the curtain rail itself, which is used to attach and hold curtain hooks or the like. It therefore only the curtain panel according to the invention has to be attached to the holding surface, it then becomes the holder to attach the cover automatically also attached. The elongated element and the bracket are preferably made in one piece by extrusion, the curtain screen being made of an extrudable material such as aluminum or plastic material is produced. Alternatively however, the support can also be attached to the elongate element during manufacture by any suitable method be attached. The curtain cover can be made with an adhesive connection layer for immediate installation or with openings be provided to mount the curtain screen by means of screws. Alternatively, any suitable Arrangement for attaching the curtain cover to a holding

709884/1007

provide area.

The elongated member having a generally U-shaped cross-section is preferably formed by extrusion from a suitable material, and close rectangular end pieces the ends of the elongated member to form an open box structure. The end pieces can be in their positions latched or fastened there. The brackets for the cover have the shape of a groove or grooves that are formed during extrusion and provided in one, two or all of the walls of the U-shaped cross-section can. A sufficient number of retaining grooves can be provided in the panel, if this is desired, around normal curtains or hangings, a roller blind and curtains or net curtains, if the screen is placed over a window opening will. The screen can be connected to a holding surface by means of an adhesive; it can be screwed onto the holding surface or by any other suitable means. Furthermore, the front surface of the diaphragm can with Embossed or otherwise decorated during production.

According to a further feature of the invention, a screen is provided for use over a passage or window, which includes an elongate member having a generally U-shaped cross-section transverse to the longitudinal direction, and which contains a bracket for attaching a roller blind or roller curtain and a roller blind that is inside the U-shaped Cross-section is carried by the bracket.

According to one embodiment of this further feature of the invention, the curtain screen contains a roller blind arrangement, which is carried on arms that engage in a groove or channel based on the U-shaped cross-section is trained. The cover can be installed over a window or a passage by using an adhesive layer,

709884/1007

be fastened by screws or by brackets that are screwed or connected to the holding surface.

Conventional installation of blinds requires that the arms for both ends of the blind be attached, for example by means of screws, in generally relatively inaccessible locations. When a roller blind is installed over a window, for example, it is necessary that it be placed as close as possible to the window, and this generally means that the arms should be installed virtually adjacent to the side walls defining the window opening, so that the blind covers the entire window. It should be noted that this can be a difficult operation. Using the above-mentioned embodiment of the invention, the arms are inserted into the groove or channel of the elongate element and the shade is tensioned and secured on the arms before the screen or device according to the invention is put in place. The arms and the shade can thus be easily assembled, and then all that is required is that the elongate element is attached over the window opening. If an adhesive layer is used, the screen or the device according to the invention can only be installed by applying pressure. However, if the support surface is uneven, adhesive arms can alternatively be used on both sides of the elongate element. With this installation, the elongated element can be cut exactly to fit the opening, in which case the need for end pieces is no longer necessary.

According to a further Ausfüttitungsfonn of the invention extend There are essentially two channels along the entire length of the elongate element and serve as supports for covers in fora of a blind and a curtain. Retaining arms for a roller blind engage in a channel, and a curtain rail is recorded in the other channel. In this way delivers

709884/1007

the inventive device for a window opening both a roller blind and a fastening device for suitable curtains. End pieces are preferably used to close off the ends of the elongate element, and the device or screen according to the invention is preferably, for example, over a window opening by means of a Adhesive layer attached, which is preferably provided on the back of the U-shaped elongate element. Alternatively the device according to the invention can be screwed or fastened in its end position, or an arm can be provided which is attached to the holding surface in order to fit into corresponding complementary openings, channels or slots to engage in the elongated element.

While the listed embodiments can be purchased properly sized for a specific application, or otherwise cut to length with regard to the desired choice of roller blind, allows another Embodiment of the present invention provides a degree of length adjustment of the elongated element. In this embodiment, the elongated element contains two elongated end pieces, which each grip axially sliding over one end of a central part. In that the end pieces slide axially relative to the central part are displaceable, a desired length of the device according to the invention can be set. Alternatively can it is sufficient to make only one end piece adjustable. Then a roller blind and a curtain rail can be used desired length can be installed.

In the event that only a roller blind is to be held, the arms can be used in short channels that are attached to the both end pieces are present, the channels extending axially along the elongate member. In the middle part no channel is required. However, if a curtain fastening device is to be provided

709884/1007

A channel is preferably also provided in the middle part to allow the Distribute the weight of the curtain, with the ends of the curtain rail in short, axially extending channels are located in the end pieces and are recorded there.

In the embodiment described, the elongate member has a generally U-shaped cross section to the longitudinal direction, which is preferably produced in one piece by extrusion. The elongated element can, however also alternatively in sections, e.g. the front and rear walls, the upper wall, and these can be produced Connect sections together.

In the embodiments of the present invention that include a roller blind, the roller blind has a tendency to become to roll up towards one end, unless the roller blind is caused by a substantially downward movement is released. In this way, the roller blind can get tangled up on a holding arm and not run back fully. Around To overcome this problem, a generally circular member is freely rotatable at either end of the roller blind appropriate. The generally circular element is preferably in the form of a cup-shaped washer.

If the case is considered in which an unrolled roller blind is to be withdrawn by a release movement, the differs to the left in relation to the vertical direction, the left-hand edge of the roller blind forming the blind touches it Materials the cup-shaped washer on the left-hand end of the roller blind as the blind retracts, whereby the disc is caused to rotate while the blind material is in the required central position Position is brought by force win effect. Alternatively, the generally circular element can also be a flat one Be washer. The advantage of the cup-shaped

709884/1007

Washer consists, however, in the fact that in the event that the blind material runs over the washer, no sharp edge can touch and damage the blind material. Furthermore, the generally circular element can be designed as a rib construction, and the circular element can be made in any of the desired shapes from any suitable material, e.g., plastic material or metal will.

While the elongated element has an aesthetic appearance due to its natural color or surface design a fabric or rigid outer panel, if desired, can be attached to the elongate member to adapt the device according to the invention to its environment.

In the following, exemplary embodiments of the invention are explained in more detail with reference to the drawing. Show it :

709884/1007

The embodiment of the invention shown in Fig. 1 shows an elongate element 1 with a generally U-shaped Cross-section transverse to the longitudinal direction. In use, the elongated element is inverted as shown, so that it has a front wall 2 and a rear wall 3 'which extend from the top wall 4 downwards. from the lower surface of the upper wall 4 extend two ribs 5, which extend over the entire length of the elongated Elements extend and together form a support channel 6. It should be noted that this channel is towards the center the top wall 4 is offset for reasons which will be explained below. The elongated element with the front, the back and top walls 2, 3, 4 are made together with the ribs 5 by extrusion of a plastic material. However, any other suitable extrudable material such as aluminum can alternatively be used. An arm 7 engages at each end of the support channel 6, one arm (see FIG. 1) with a cross-shaped Opening 8 and an offset opening 9 is provided, while the one engaging the other end of the channel 6 Arm (not shown) has corresponding circular openings. A conventional roller blind arrangement, in general denoted by 10, is carried by this arm, wherein the spring-tensioned end 11 of the roller blind engages in one of the openings 8 or 9, while the free-running The end of the roller blind runs into the corresponding circular opening in the other arm 7. The choice of opening 8 or 9 depends on the size of the blind to be installed. The main criterion for pulling part A of the roller blind is: to be placed as close as possible to the rear wall 3, i.e. to run as close as possible to the window, and the openings 8 and 9 represent the only degree of adjustability in the offset channel 6. The Cross-shaped opening 8 only allows easier insertion of the tensioned end 11 of the roller blind. The ends of the elongated element are closed by end pieces 12

709884/1007

sen, bracketed in their position. Alternatively, the end pieces can be fastened or in their position Welding are brought. In order to prevent the roller blind from becoming entangled in an arm 7 during operation, a rotatable, cup-shaped washer 15 is provided at each end of the roller blind. So if the When the roller blind rolls up against one end of the roller blind, it contacts the washer 15, which rotates with the blind, and drives the blind back to the desired central position. Since the washer 15 is cup-shaped, touches only a small edge area covers the arm 7 and the washer therefore actually rotates relatively freely.

In order to attach and fix the device or screen according to the invention, an adhesive layer 13 is provided on the upper surface of the upper wall 4 between ribs 14. The screen can be fastened in this way in that only the elongate element is pressed against a holding surface until the ribs 14 allow the screen to rest on the holding surface and align with it. If desired, small areas of adhesive material can also be provided in place of the continuous strip layer.

Alternate means of attachment are shown in Figures 1A and 1B the bezel provided in place. These alternative means are suitable for fastening the panel, if a flat holding surface is not available. The fasteners of Figure 1A include two Brackets 16 and 17, which are provided with an adhesive strip 18 are. The bracket 16 has a lip 19 which rests around one end of the upper wall 4 of the elongate element 1 and extends into the channel 6. The other bracket 17 has a lug 20, which extends around the other end of the upper Wall 4 can put. When attaching the 16 and 17 in

709884/1007

of the desired location, and through the engagement of one end of the elongate element in the bracket 16, the elongate Element are set so that the other end of the upper vvand 4 engages in the approach 20 of the bracket 17. By applying pressure the extension 20 bends and clings to the other end of the upper wall 4 and thus secures the inventive Device in place. For safety reasons, a screw (not shown) can go through the approach 20 and introduced into a threaded hole 21 in the arm 7 (see. Fig. 1). In the alternative embodiment According to FIG. 1 B, the brackets 16 and 17 are screwed onto the holding surface.

Another embodiment of the invention is shown in Fig. 2, and the same reference numerals are used for parts that are equivalent to parts of the embodiment of Fig. 1. The main difference between the embodiment of FIG. 2 and that of FIG. 1 is that a curtain support rail 22 is provided. This support rail 22 has a generally I-shaped cross-section, one part of which engages in a channel 23 which is defined by the ribs 24 which extend downwards from the top wall 4; the channel 23 extends over the entire length of the elongate element. The support rail 22 has a recess 25 which, when in use, receives curtain hooks 26 and enables the curtain hooks 26 to slide back and forth in this recess 25. As can be seen from Fig. 2, the support rail 22 can be attached to the channel 23 in two ways. In the position shown, the curtain hooks 26 are at the greatest distance from the front wall 2. If, on the other hand, the rail 22 in the channel 23 is reversed, the curtain hooks 26 can be brought closer to the front wall 2. This is only an option for a special attachment.

709884/1007

The device of FIG. 2 is held by using an adhesive layer 27 provided on the rear wall 3 is. Alternatively, the device can be screwed to a holding surface. Figures 3A and 3B show one another possible form of a bracket. This has a finger bracket 28 that is screwed on or otherwise the holding surface can be attached. The bracket has a number of finger-shaped lugs 29 in corresponding Openings 30 can engage in the rear wall of the device according to the invention.

In the embodiments described above, the elongate element is selected, cut to the desired length or been dressed, wherein the blind or the blind and the curtain rail should have suitable dimensions. As an alternative to having elongated element as desired cut, is in Figures 4 to 6 a telescopically extendable version of the device according to the invention or aperture. Again, the reference numerals already used in FIGS. 1 and 2 were also used in FIGS. 4 to 6 for equivalent parts. The elongated one Element in Figures 4 to 6 is an elongated central portion 31 with a generally U-shaped cross-section transversely to the longitudinal direction and two elongated end pieces 21. Each end piece 32 snugly fits over one end of the central portion 31 and has a top wall 33 »side walls 34 and one End wall 35, the lower ends 36 of the side walls 34 are bent upwards to grip the lower edges of the front and rear walls 2 and 3. By sliding displacement of the end pieces 32 relative to the central part 31, the length of the diaphragm can therefore be adjusted. In the event that only one If the roller blind is to be installed, short channels 37 are only provided in the end pieces 32, these short channels 37 are disposed in the lower surface of the top wall 33 adjacent to the end wall 35. The arms 7 engage in this short channels. However, if a telescopic aperture for a

709884/1007

Roller blinds and a curtain bracket are required, as shown in As shown in FIGS. 5 and 6, in addition to the short channels 37 and 39 in the end pieces 32, there is a channel 58 in the middle part 31 provided to support the rail 22. By choosing the correct length of blind, and by cutting the rail 22 on the correct amount, the diaphragm can be adjusted to fit by moving the end pieces 32 relative to the middle part 33.

While in all of the embodiments described so far, the U-shaped elongate element as a one-story extrusion mold is made, the elongated element can be removed from large screens, which can prove to be unwieldy interlocking, extruded parts. Such an example is shown schematically in FIG. the top wall 4 has bulbous lugs 40 on all side edges, and the front and rear walls 2 and 3 have corresponding ones matching recesses 41. These parts can therefore, as shown on the right in FIG. 7, be connected to one another form. This arrangement of parts which can be plugged into one another can be used in all embodiments within the scope of this invention use.

The front wall is preferably decorated with ribs which are produced during manufacture, for example during extrusion. However, in order to enhance the aesthetic appearance of the device of the present invention, an outer panel 42 (see FIG. 1) may be attached to the elongate member by any suitable means.

According to the present invention, a screen or device is created that combines a roller blind or a roller blind with a curtain rail, and which can be easily installed with respect to known types of attachment.
