Description

The invention relates to a horizontal blind for window or door openings according to the preamble of claim 1.

A generic horizontal blind with a top rail and a bottom rail, both of which are held freely displaceable in the vertical direction on clamping cords, for example, from EP 1 489 258 A1 known. The horizontal blind comprises a spring mechanism, so that the upper rail and lower rail can be kept in a tensioned state regardless of their position. Both the upper rail and the lower rail can be moved independently of each other on the clamping cords to change in this way the size of the attached between the upper rail and the lower rail sunshade.

A disadvantage of the known horizontal blinds is that the user to resize either the top rail or the bottom rail touch with his hand and then move manually. In some installation situations, for example, when installing the horizontal blinds in the roof area, it is for the user due to the respective Height sometimes not possible to reach both the top rail and the bottom rail by hand. If the upper rail is mounted, for example, at a height of more than 2.50 m, a manual displacement of the upper rail by directly moving the upper rail itself is no longer possible.

Based on this prior art, it is therefore an object of the present invention to propose a new horizontal blind in which the upper rail or the lower rail can be operated remotely either by pressing the respective other rail.

This object is achieved by a horizontal blind according to the teaching of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

The horizontal blind according to the invention is based on the idea that on the horizontal blind a coupling device is provided with which the upper rail and the lower rail can be mechanically connected to each other. The coupling device has the task, in the event of their intervention in upper rail and lower rail to ensure that the upper rail and lower rail are held in the same distance from each other. This then ensures that by shifting only the lower rail or only the upper rail a simultaneous displacement of the respective second rail is achieved. As a result, the user can then reach by the inventive coupling of the upper rail and the lower rail by the coupling means a remote control by pressing the respective other rail. For example, if the upper rail is at a height of more than 2.50 m, it can be achieved by engagement of the coupling device that the user simultaneously displaces the lower rail, which is for example at a height of 1.50 m realized the top rail. By decoupling the coupling device, it is then possible in turn for the two rails to be positioned independently of one another on the tensioning cords.

The type in which the coupling device is designed for mechanical coupling of the upper rail to the lower rail is fundamentally arbitrary. According to a preferred embodiment, it is provided that the coupling device comprises a left and a right pull loop.

The two pull loops are preferably produced by annular connection of the two ends of a cord section. Such textile pull loops can be integrated with the same construction elements as the tension cords in the horizontal blind and installed constructively. In particular, the same deflection can be used for deflecting the pull loops at certain deflection points, which are also used for the tension cords. To store the pull loops on the window or door opening, it is particularly advantageous if both pull loops are deflected in each case at an upper and a lower deflector, wherein the deflection points are arranged in the context of the window or door opening. The two pull loops are divided by the two deflection points each in an outer center and an inner center. To implement the coupling device, it is furthermore particularly advantageous if both pull loops are each firmly connected to a fixing element with the upper rail or the lower rail. This means in other words that it is ensured by this fixation of the pull loops on the upper rail or the lower rail that move the pull loops each synchronously with the displacement of the corresponding rail.

Furthermore, it is preferred if both pull loops are each detachably connectable by means of a manually operable fixing device to the upper rail or the lower rail, which does not comprise the fixing elements. By engagement of the fixing device, the corresponding rail then be attached to the pull loop, so that in this way the movement of the other rail is transmitted via the two pull loops on the rail with the fixing device. This means in other words that can be achieved by manual actuation of the fixing device that the upper rail and lower rail are mechanically coupled together by the Zugschlaufen and the movement of a rail is transmitted to the other rail. By loosening the fixing device, it is then possible in turn for the two rails to be displaced independently of one another on the tensioning cords. According to a preferred embodiment, it is provided that the fixing element and the fixing device, which are associated with a pull loop, come into engagement together at the outer center or together at the inner center of the respective pull loop.

The way in which the fixing device is designed constructively, in turn, is basically arbitrary. Particularly simple and inexpensive, the fixing device can be formed by using two jaws, and by actuation of an actuating device, the two jaws can be approximated to each other and the pull loop can be clamped between the jaws.

In order to realize the coupling of the two rails to each other by the two pull loops, it is necessary that both fixing devices are clamped to the respective associated pull loops. In view of improved ease of use, it is therefore advantageous if both fixing devices are simultaneously fixed by actuation of a common actuating device on the respective associated pull loop. As a result, the user can fix both fixing devices on the pull loops solely by the actuation of the common actuating device and then realize a coupled displacement of the two rails on the clamping cords.

In the realization of the horizontal blind according to the invention, the pull loops between the two rails along the in between arranged sun protection device run. To realize this in a simple manner, it is particularly advantageous if the outer center and the inner center of the Zugschlaufen are threaded through recesses in the sun protection device.

Particularly cost, this threading can be realized by the recesses of the sun protection device, if the recesses are used, which are provided in the sun protection device anyway for the threading of the tension cords.

According to a preferred embodiment variant, it is provided that the outer center and the inner center of the pull loops are each led out of the upper rail or the lower rail on the left and the right front side.

Which type has the horizontal blind with respect to the sunscreen used, is basically arbitrary. According to a preferred variant, the sunshade device is formed by a plurality of lamellae, which are held in the conductor cords and can be adjusted in their inclination.

Alternatively, as a sun protection device and a Plisseebehang with an expandable and collapsible, multiply pleated and a plurality of parallel folds having sheet formed.

Two embodiments of the invention are shown schematically in the drawings and are explained below by way of example.

a second embodiment of a horizontal blind according to the invention in a lateral view.

Fig. 1 shows a horizontal blind 01 with a top rail 02 and a bottom rail 03 in a lateral view. The upper rail 02 and the lower rail 03 are mounted vertically displaceable on clamping cords, wherein the tension cords in Fig. 1 are not shown. Between the upper rail 02 and the lower rail 03 is a variable in size sun protection device 04, which is formed by a plurality of fins 05. The slats 05 are adjustably mounted in ladder cords in their inclination, wherein the conductor cords in Fig. 1 are not shown.

To increase or decrease the shadow of the horizontal blinds 01, the upper rail 02 and the lower rail 03 can be moved independently vertically, whereby the two rails 02 and 03 are either approached to each other or away from each other.

For coupling according to the invention of the upper rail 02 and the lower rail 03, a coupling device is used on the horizontal blind 01, which is formed by two pull loops 06 and 07, two fixing elements 08 and 09 and two manually operable fixing devices 10 and 11 in cooperation with an actuating device 12. The operation of this coupling device will be explained below by way of example.

At the in Fig. 1 state shown, the two fixing devices 10 and 11 are not engaged with the two pull loops 06 and 07. Will now, as in Fig. 1 indicated, the lower rail 03 moved vertically, the fixing devices 10 and 11 thereby move relative to the two non-moving pull loops 06 and 07.

Fig. 2 again represents a state in which the fixing means 10 and 11 are not in engagement with the pull loops 06 and 07. Now the upper rail 02, as in Fig. 2 indicated, moved vertically, so the two Zugschlaufen 06 and 07 are mediated by the fixing 08 and 09 entrained, so that the pull loops 06 and 07 are moved through the two non-engaged fixing devices 10 and 11.

Fig. 3 now shows the horizontal blind 01 after actuation of the actuator 12. By pressing a wedge-shaped actuator 13, two push rods 14 are pushed apart horizontally and bring in this way the fixators 10 and 11 at the inner center 15 and 16 for engagement. The two pull loops 06 and 07 are deflected at deflection points 17 and 18 or 19 and 20, wherein the deflection points 17 and 18 divide the pull loop 06 into the inner center 15 and the outer center 21 and the deflection points 19 and 20, the pull loop 07 in the Innentrum 16th and divide the outside center 22. The deflection points 17 to 20 can be arranged on the frame of the window or door opening.

How out Fig. 3 can be seen upon actuation of the actuator 12, both the fixing elements 08 and 09 and the fixing means 10 and 11 at the respective inner center 15 and 16 of the two pull loops 06 and 07 fixed. Will now, as in Fig. 3 indicated, the lower rail 03 is displaced vertically, so by fixing the fixing means 10 and 11 to the pull loops 06 and 07, the corresponding adjusting movement synchronously transmitted via the inner center 15 and 16 on the fixing elements 08 and 09 and thus on the upper rail 02. As a result, so all operating movements of the lower rail 03 synchronously transmitted to the upper rail 02 and vice versa, all actuating movements of the upper rail 02 synchronously transmitted to the lower rail 03 when actuated actuator. After releasing the actuator 12, the two rails 02 and 03 then again, as in Fig. 1 and Fig. 2 shown to be moved vertically independently of each other.

The fixing devices 10 and 11 are each of two clamping jaws 23 and 24 (s. Fig. 1 ) educated. The two pull loops 06 and 07 with their inner center 15 or 16 and their outer center 21 and 22 are threaded through recesses of the slats 05.

Fig. 4 shows a second embodiment 25 of a horizontal blind according to the invention. The same functional elements of the horizontal blind 25 are designated by the same reference numerals as on the horizontal blind 01. In Fig. 4 are the durchlinierten tension cords 26 on which the upper rail 02 and lower rail 03 are mounted vertically displaceable, indicated schematically. By means of suitable deflection of the pull loops 06 and 07 it is achieved that the pull loops 06 and 07 are led out on the end faces 28 from the upper rail 02 or the lower rail 03. The deflection points 17 to 20, at which the pull loops 06 and 07 are deflected, are arranged on the frame 29 of the window or door opening. By operating the actuator 12 with the shortened push rods 14, the bottom rail 03 can be connected via the fixing devices 10 and 11 connected to the pull loops 06 and 07, so that thereafter all movements of the upper rail 02 are synchronously transmitted to the lower rail 03 and vice versa all movements Lower rail 03 are transmitted synchronously to the upper rail 02.
