The box also houses a smaller roller for an extending awning which is deployed outside the window/door opening. The awning is fitted with support braces which can be adjusted to hold the awning at different angles. A variation has the awning ducted partway down the same feed at the roller shutter and then extending outwards to provide the selected amount of shade.

Description

Structural unit of blind box.

The invention relates to a structural unit of blind box, with a box body and a frame of shutter arranged in it, and with an awning installed in the case body with winding shaft and awning key rolled over, the awning being configured as an extensible awning with awning canvas unrolled at least partially in sight side in the state of use in front of a window plane and / or in front of a plane of the blind armor.

A structural unit of blind box of the structure indicated at the beginning is described in JP document 2001-090451. There are the armor of blind and awning in separate housings, respectively, or in parts of the case body housing.

Within the framework of document DE 198 55 166 A1, further describes a combination of a shutter box with a blind armor found in it as well as with a Conventional awning not realized as an extensible awning. In this case, it is a combination of blind and curtain for the Impression image transmission. In this case, the axis of winding for the awning canvas is not arranged in the body of the box, but rather is at the height of the song top of a window or a window pane.

In the known awning it is a so-called awning vertical, which always extends parallel to the opening of the wall behind or parallel to the window that It is installed there. This is inconvenient in the sense that only insufficiently taken into account different mounting conditions, variable sun states, the desired lighting relationships in the space that find behind, etc.

In addition, JP 01083794 mentions a structural unit of blind box of the structure described at the beginning. Here a drive of relatively complicated zipper for the extensible awning. From this way, only this single awning can be combined with the known box body.

The invention is based on the technical problem of further develop a structural unit of box shutter of this type such that the respective awning is in conditions of being able to take into account very different requirements and specifically with a simple structure and favorable cost. In addition, the possibility of retrofitting the awning without problems.

For the solution of this approach of problems, a structural unit of blind box of the type mentioned at the beginning is characterized in the context of the invention because the body of the box has at least one point of separation configured as theoretical break point, to be able to install the extensible awning inside.

The extensible awning according to the invention has, in general, of an extender or an extension device, which ensures that the corresponding awning canvas adopts at least partially in the side view a bend in front of the plane of the window and / or the plane of the blind armor. This way different states of the sun can be taken into account, the geographical features, user requirements, etc. for the first time in a wide scope.

Thus, for example, an extensible awning of this type allows, in the summer, with a maximum shade formation, always still passing a sufficient amount of light to inside the space behind, without having to resort to artificial light here. This is a very clear advantage. in front of the vertical awning used in the state of the art, which almost completely overshadows a space behind. In addition, the extender or the extension device enables, in general, the regulation of different angles of the canvas of the awning with respect to the window plane and / or the plane of the blind armor. This way you can control different sun states, different times of the year as well as different requirements of the people who are in the shadowed space.

It has been revealed that it is advantageous that the awning extensible be configured as an articulated arm awning, of box, drop arm, basket or similar. In the case of a articulated arm canopy, articulated arms add up, like the function of the extender or the device of extension and can be extended to a greater or lesser extent to achieve the desired shadow effect.

In the case of a cashier's whole it is in the most cases also of an articulated arm awning, whose awning canvas, including the articulation arms, are housed in a separate box. An embodiment of this type is specially predestined to be installed in the body of the box within the framework of the invention. Obviously, each of a box awning can also be installed in the body of the box.

In addition, the invention proposes as a canopy Extendable a drop arm awning. An awning of this type is characterized by a drop tube (loaded with weights) that, in combination with one or several extendable rails, it deals with a automatic way of a layered awning canvas arrangement with respect to the plane of the window and / or the plane of the armor of the blind during the unwinding of the awning canvas from the winding shaft. In a similar way a called a marquee, which can also be used in the framework of the invention. This is characterized because the awning canvas is guided vertically in the upper area and only extends down below in a guide tube.

Finally, in the extensible awning included by the invention it can also be a so-called awning of basket, which has an extensible device, which has arches basket that converge in each case at a pivot point. These basket bows can support each other in the dejected state inward and tense, in the unfolded state, a segment spherical, for example a quarter sphere. Obviously also other extensible all are conceivable, provided that it is guaranteed simply that the awning canvas is at least partially layered  in the side view with respect to the plane of the window and / or the plane of the blind armor, and specifically in the state of use.

Although the invention also comprises configurations, in which the awning is installed outdoors of the body of the box, however, it has been revealed that it is especially advantageous that the blind and awning armor extensible are arranged in common inside the body of the box, since in this way the body of the box assumes also the function of a protection box for the awning. In this case, the blind armor is placed most of the times centrally in the body of the box and the awning Extensible is placed in a corner area. In this context, it has been revealed that it is favorable for the extensible awning be arranged on the outer side in front of the armor of the blind. This is best achieved when the winding shaft for the extensible awning is arranged in a front corner top of the blind box or the body of the box and in a vertical view it is arranged in front of the axis of winding for the armature of the blind, and specifically of the way described for a fabric rolling shutter metal within the framework of EP 0 724 064 A1. Evidently, this awning can be completed inside also with an awning additional exterior.

But, in addition, you can also conceive of the same way and it is possible to install the winding shaft for the Extendable awning in the upper or lower rear corner. Further, the invention naturally also includes configurations, in that the winding shaft for the extensible awning is not arranged in the corner area, but it is rather under the armor of the blind, as described in combination with an insect protection grid in the document DE 39 36 343 C2 or also in document DE 94 13 520 U1.

Usually, to the body of the box are associated two pairs of guide rails, namely, on the one hand, guide rails of the blind armor and, on the other hand, awning guide rails. In this case, the guide rails of the awning are arranged in front of the guide rails of the blind armor overlooking a wall opening that is found behind or overlooking a window. This is done this way because with it, even when the awning canvas Extendable is angled, armor can be activated without collision of the blind behind. In addition, this way you can use the blind armor in a complementary way (or alternative) to provide shade.

Obviously, it is also possible to drive the blind armor in front of the awning. Nonetheless then it must be ensured that when the stretchable awning canvas is layered, the blind armor does not damage the rails extendable, articulated arms, etc. This can be done in the simplest case with the help of a control facility, which controls and activates in common the armor of the blind and the extensible awning. Here it is conceivable to try, with the help of control installation, which, when the fabric of the extensible awning is layered, the blind's armor only silk lowered in a certain predetermined measure, so you don't have to fear collisions with the extensible device.

Obviously, the control facility is, also, in a position to detect the respective position of the blind armor the same as the extensible awning, and in concrete with the resource of one or several sensors. One or the other way, the control facility takes care that the operation respective of the armature of the blind and the extensible awning be mutually adapted - as described in the example -.

So that the extensible awning can be installed a simple and trouble-free way in the body of the box (also later), this body of the box has the point of separation already described to be able to install the extensible awning inside. At this point of separation it is a point theoretical breakage in the respective walls of the body of the box. A breaking point of this type can be easily defined because the respective walls are usually made as a profile plastic hollow

Finally, the awning canvas has on the side exterior most of the time of a decoration, an impression advertising, etc. In this way, accents can be applied optics with the extensible awning according to the invention, which influence an essential measure in the overall appearance of an equipped building in this way. All this is achieved with a structure extraordinarily safe, because the extensible awning can be integrate with your extensible device without problems in the body of box. In addition, the awning can be mounted without problems later in the case that the body of the box is equipped with one or several separation points. Here you can see The essential advantages.

The invention will be explained in detail below. with the help of a drawing that represents only an example of realization; in this case:

Figure 1 shows a structural unit of blind box according to the invention in the section with reinforcement of articulated arm blind and awning.

Figure 2 shows an embodiment Modified blind unit structural unit according to invention with blind frame and drop arm awning.

Figure 3 shows again a form of modified embodiment of the structural unit of blind box according to the invention, with blind and canopy armor, the canopy being arranged on the outer side in front of the blind armor, and

Figure 4 shows a modified variant according to Figure 3 with canopy installed in the lower corner rear

In the figures, a unit is represented structural blind box, which is composed in its structure basic of a box body 1, a blind frame 2 arranged in it and an awning 3 that is installed in or next to the body of the box 1 with winding shaft 4. Since the body of the box 1 is installed on a window only indicated, it In this case, it makes an overlapping box, although, naturally, the enclosed boxes are also conceivable. At winding shaft 4 is treated, within the framework of the example of realization of a roller shutter axis, that is, of a shaft, in general, hollow with spring arranged inside, which pulls an awning canvas 5 rolled over to its extended position. Is  that is, the awning canvas 5 can only be unwound against the spring force of the roller shutter shaft 4.

This force for unrolling the canvas the awning can be applied most of the time mechanical or electrical In the case that the awning 3 is about an extensible awning 3, more precisely said of an arm awning articulated (see figure 1), a manual driven gear or electrically, not expressly represented, deals with the winding shaft or the roller shutter shaft 4 is turned against the force of the spring, so that the corresponding 6 articulated arms. These articulated arms 6 they drag with their front edge 7 the awning canvas 5 that is fixed there, so that the shadow effect is guaranteed required, in general, from awning 3.

The awning of the articulated arm according to figure 1 It is in the framework of the embodiment on the side outside in front of the armature of the blind 7, being arranged its winding axis 4 in the side view in front of the axis of corresponding winding 8 of the blind armature 2. From the same way, in the variants according to figures 2 and 3, in the that also the winding axis 4 of the extensible awning 3 is found on the outer side in front of the blind armor 2 and, moreover, the winding shaft 4 is arranged in the vertical view in front of the winding shaft 8 of the frame of the blind 2.

It is possible to insert the articulated arm awning according to figure 1 in a separate housing in the case body 1. However, usually the body of the box 1 assumes the same time also the function of a protective housing for the extensible awning 3.

A point of 2 is recognized in Figures 1 and 2 separation 9 in the body of the box 1 or its side wall front 1a. This front side wall 1a is made, as also the remaining walls of the body of the box 1, that is, the top wall 1b, the rear side wall 1c and the bottom board or Well the bottom wall 1d as a hollow plastic profile wall. In this way, the point of respective separation 9, so that the extensible awning 3 can be insert into the body of the box 1. This separation point 9 it even allows a rear mounting of the extensible awning 3.

Within the framework of the embodiment according to the Figure 2, an arm awning of 3 is used as an extensible awning drop, which has a drop tube 10, which is filled usually with weights. The forces of weight caused by this way they take care that the awning fabric 5 is unwound from the corresponding winding shaft 4, when a brake or similar. Conversely, the awning canvas 5 can be roll again with the help of a drive on the shaft winding 4.

In any case, it is guaranteed that the awning or either the extensible awning 3 is extended at least partially in the state of use represented with respect to a plane F of the window or with respect to a plane E coplanar of the armor of the blind. This means that at least a part of the awning canvas 5 is unwound in the side view in front of the plane F of the window and / or in front of plane E of the blind armor. He corresponding angle α of the inclined position of the canvas of the fabric 5 is usually predetermined through the extensible device configuration 6, 7, but, in principle, It can be varied.

Within the framework of figures 3 and 4, it is used finally as an extensible awning 3 a so-called canopy with tube drop 10 and guide tube 11 as well as with extendable rails 12. The mode of operation of this marquee and its structure possible are described in the state of the art, for which purpose it is made reference only by way of example to document DE 199 49 163 C1.

In the framework of the configuration according to the figure 3, the winding axis 4 of this canopy is of new on the outer side in front of the blind armor 2 and otherwise, the winding shaft 4 is placed in the vertical view in front of the winding shaft 8 of the frame of the blind 2. On the other hand, the canvas of the awning 5 extends, in the configuration frame according to figure 4, on a device deviation 13, because here the extensible awning 3 or the marquee are arranged in the lower back corner of the body of the box 1. Instead, the armor of the blind 2 is placed in each case centrally within the body of box 1, while extensible awning 3 is placed - as described - in the corner area of the body of the box one.

In the framework of the configuration according to the figures 3 and 4, guide rails 14 of the awning are provided for driving the awning canvas 5. On these guide rails 14 of the awning extend slide rails not shown expressly, whose free ends are connected to each other to through guide tube 11. On these slide rails are mounted, on rotating bearings not shown neither, the extendable rails 12, whose free ends are connected to each other through the drop tube 10, and in particular of the manner described in detail in document DE 199 49 163 C1 already mentioned at the beginning. Obviously, they are also conceivable other configurations of the extensible device 6, 7, 10, 11, 12 and are encompassed by the invention.

In any case, under the variant according to figure 3, the guide rails 14 of the awning are arranged in front of the corresponding guide rails 15 of the armor of the blind, overlooking the opening of the wall that is behind or with views of the window that is behind. In this way, it is ensured that the extensible awning 3 does not can collide in the state of use with the awning canvas 5 angled or with the blind armor 2.

In order to ensure this also in the variant according to figure 4 with the guide rails 15 of the blind which is found there in front of the awning guide rails, the object of the invention uses a control installation 16. This  control facility processes signals from two position sensors 17, which monitor the opening state, on the one hand, of the reinforcement of the blind 2 and, on the other hand, of the extensible awning 3 and notify control facility 16.

To guarantee now that, with the awning canvas layered 5, under the variant according to figure 4, the 2 blind armor does not collide with extendable rails 12 found there, the shutter armor stops 2 after a certain number of unwinds. This presupposes, naturally, that also the corresponding drives 18 and only indicated, on the one hand, of the blind armor 2 and, on the other hand, of the winding axis 4 of the extensible awning 3 be driven in a corresponding manner by the installation of control 16. Obviously, control installation 16 can be send by remote control, but this is not mandatory. Also they time controls are naturally within the framework of the invention. In the same way, the control installation 16 is not limited to the functions described above. Instead of this way you can perform intelligent control of the Armature of the blind 2 as well as the extensible awning 3, and specifically only, for example, within the framework of a control of day / night, solar control, etc. Without a doubt, the installation of control 16 described can be used in combination with all possible variants (and shown).

The possibility of equipping the awning canvas 5 on the outer side with a decoration, a advertising printing, etc., to influence in a selective way about the general optical character of a building equipped with it. In  This case, the awning canvas is, of course, not just a fabric, but it can be conceived in the same way also used in This place a printed or unprinted plastic sheet. Also I know they comprise laminated materials, i.e. rolled fabric tapes Multi-layered
