Description

The invention relates to a roller shutter box, with a roller shutter disposed in its interior, which is received by a telescoping roller shutter shaft, and with an up / Abwickeleinheit for the roller shutter shaft.

As a rule, the roller shutter box is composed of a cuboid box body with side covers to its lateral conclusion. In addition, the box body regularly has a floor board, which may have a revision flap or even designed to be foldable. The roller shutter shaft is supported by means of cheeks, which are placed in the context of the generic state of the art according to DE 39 20 200 A1 inside the box body. This leads to a structurally high effort, because the cheeks must be realized in addition to the side covers, which also brings cost disadvantages.

Roller shutter boxes are known in a variety of configurations. So you know attachment boxes that are front set in front of a door, a window or the like and often used in renovations use. The same applies to Aufsetzkästen, as described for example in DE 297 00 160 U1. Such a Aufsetzkasten requires only a wall opening, which corresponds to that for the associated window or door. Compared to original equipment variants so the masonry above the upper frame plate leg of a window is not widened.

Such Aufsetzkästen have proven to be complete because they are composed as a complete unit of, for example, windows and attached to the upper frame leg leg shutter box in the workshop or on the site completely with the window. Supplementary masonry / caulking is not required. However, a problem is the operation of the arranged in the box body roller shutter during winding and unwinding. Because because of the adapted to the width of the window or door opening size of the box body in a Aufsetzkasten the required and recorded on a belt reel roller shutter is visible along a side Blendrahmenschenkels out.

This not only bothers you from an aesthetic point of view, but often leads to the fact that usually only narrow roller shutter belts can be used. However, these are susceptible to wear and less grip and therefore practically unsuitable for wide and heavy roller shutter. In addition, in the known Aufsetzkästen usually the up / unwinding is placed inside the box body, so that the replacement of the worn roller shutter is difficult.

For this reason, DE 39 20 200 A1 has already proposed a telescoping roller shutter shaft, which is mounted with the aid of two cheeks provided inside the box body. In this case, a gurtrollen side cheek is placed with a width of the belt roll corresponding distance from the masonry body inside the box body. The other cheek holds a predetermined distance from the masonry. This valuable space for the roller shutter is given away or this has a width which covers an associated window only inadequate or works with unnecessarily wide and disturbing roller shutter guide rails.

Although the roller shutter is hidden in that it is not performed parallel to the vertical frame leg on this, but outside the box body on the externally placed up / unwinding. This means that even wider roller blind dress copies can be used. However, this is with the previously outlined disadvantages of limited width and consuming storage of the roller shutter purchased. Here, the invention aims to provide a total remedy.

The invention is based on the technical problem of further developing such a roller shutter box so that, in particular, concealed roller shutter belts with sufficient width can be used with a simple construction.

To solve this technical problem, a generic roller shutter box in the invention is characterized in that for guiding the roller shutter shaft, a guide / coupling device is provided, which is mounted in a box end side realized winding side cover.

In contrast to the prior art, the winding-side side cover is therefore the box end of a box body of the shutter box, thus closing this at one end. If the other side cover is placed on the box end side, the entire installation space inside the box body is available for receiving the roller shutter shell. In this case, the roller shutter shaft can pass through the aforementioned guide / coupling device and receive the end of the up / unwinding, which may be plugged. In the region of the opposite side cover is found in this variant usually a telescoping device for the roller shutter shaft.

But it is also possible that the roller shutter shaft is connected with the interposition of the guide / coupling device with the up / unwinding. Then the roller shutter shaft quasi ends in the guide / coupling device. In this case, the guiding / coupling device is regularly as a plug-in sleeve with two plug-in receptacles on the one hand, the up / unwinding and on the other hand, the roller shutter shaft is executed. Of course, instead of the two or a socket and connecting means such as screw, rivet or locking connections can be realized.

The plug-in socket or coupling device may, on the one hand, pick up the inserted roller shutter shaft and, on the other hand, the plugged on / unwinding unit, or vice versa. D. h., The plug-in sleeve can also be designed so that on the one hand the roller shutter shaft is plugged and on the other hand, the up / unwinding is inserted into the socket.

In both cases, the guiding / coupling device ensures that the roller shutter shaft is properly connected to the up / down unit, either directly, because it passes through the guide / coupling means or indirectly by the guide / coupling device is interposed. In this case, the winding / unwinding unit is arranged outside of the box body as a whole, in the axial extension of the roller shutter shaft beyond the winding side side cover. This also explains the naming of the relevant page cover.

In order to accommodate the usually inserted into the socket sleeve roller shutter shaft, this has a plug insert which is adapted to the exterior of the roller shutter shaft. In addition, the socket has a stub shaft as Aufsteckzapfen for receiving the up / unwinding. The winding / unwinding is attached to this stub shaft. Aufsteckzapfen and plug insert form the two plug-in receptacles of the socket.

Once the roller shutter shaft is inserted into the plug insert of the plug-in socket and the up / unwinding is attached to the stub shaft of the socket, there is a continuous connection between the up / unwinding and the roller shutter shaft. This also applies in the event that the roller shutter shaft the Passes through guide / coupling device. This undergoes the desired storage in the winding side side cover box end side of the box body. D. h., The associated bearing cheek coincides with the relevant side cover, so in contrast to the DE 39 20 200 A1 is not arranged separately in the interior of the box body.

If also the second required for the storage of the roller shutter cheek coincides with the second side cover on the opposite side, the entire box body is available for receiving the roller shutter.

Thus, an underlying door, a window or the like can be covered over a large area, without having to be realized visually disturbing wide roller shutter armor guide rails side of an associated wall opening. Rather, narrow roller shutter armor guide rails are sufficient here.

At the same time, a concealed arrangement of a roller shutter belt can be realized. This usually works on the rewind / unwind unit. Since the winding / unwinding unit is usually designed as a belt reel and attached to the shaft extension provided in the extension of the roller shutter shaft on the socket, the aforementioned winding / unwinding is outside of the box body. The belt attachment is thus comparable to that in a conventional roller shutter box. It is sufficient overall to create in the wall opening only a space for the up / unwinding or the belt reel. This can be done in the simplest case by an appropriately designed stone with opening.

Preferably, the guide / coupling device has an outer peripheral side bearing ring rotatably in the winding side side cover is stored. The bearing ring can be accommodated in an associated pivot bearing. However, it has proven useful if the relevant bearing ring rolls on provided in the winding side cover several pivot bearings. Usually two pivot bearings are used, which are mounted on the foot side of a bearing opening in the winding side side cover. As a result of the weight forces occurring, the guide / coupling device rests with its bearing ring on these two pivot bearings and can roll on it rotatably. In principle, three pivot bearings can be used, which are placed in 60 ° arrangement to each other and thus cause a statically determined storage of the guide / coupling device by means of the outer peripheral side bearing ring. For cost reasons, however, you usually fall back on two pivot bearings.

For the axial support of the guide / coupling device in the winding side side cover this has a stop flange. The stop flange can interact with a counter flange in the relevant side cover. Preferably, however, the stop flange is supported on the pivot bearing or the two pivot bearings. As soon as the telescoping roller shutter shaft is inserted into the guide / coupling device or passes through it, the entire length of roller shutter shaft and optionally plug-in sleeve and winding / unwinding unit is predetermined and the roller shutter shaft undergoes an axial support in this way. The same applies to the optional push-in socket. However, if the telescoping roller shutter shaft is removed, the above-mentioned components can be easily disassembled as a result of their plug connection.

Finally, a cover to protect the up / unwinding may still be provided. This is placed on the outside of the winding side side cover and is connected in the simplest case with this. For the already mentioned recess in the wall opening for receiving the winding / unwinding unit So it is only necessary to provide sufficient space for receiving the cover at this point.

As a result, a roller shutter box is made available, which has proved particularly in the embodiment as Aufsetzkasten. That is, the Aufsetzkasten can connect to an associated frame of a window or door and is housed in a common wall opening. Consequently, the installation of the roller shutter box including window or door can be made by a single craftsman.

The production, processing and appearance is comparable to that in conventional Aufsetzkästen, as described for example in DE 297 00 160 U1. In contrast, however, a hidden Gurteinlauf is realized because the cooperating with the up / Abwickeleinheit usually roller shutter belt is not parallel and quasi on the vertical frame legs, but rather laterally on the wall along the wall opening. As a result, also suitably wide roller shutter belts can be used. In addition, the entire roller shutter box can be reversed from the inside. In this work process so stemming and / or masonry work is not required.

For the revision, that is, for example, the replacement of the roller shutter, it is sufficient to open the floorboard and / or open a flashback and push the telescoping roller shutter shaft together. Previously, if necessary, a lock of the telescopic device must be opened. Since the guiding / coupling device is released during this process, it can be transported into the box inside, including the attached unwinding / unwinding unit, through the obligatory bearing opening in the winding side cover. As a result, not only is the roller shutter shell easy to replace, but, for example, the roller shutter belt can be changed easily.

Finally, the respective storage of the roller shutter shaft in the side covers of the roller shutter box ensures that associated with the storage of the roller shutter armor safely and reliably from underneath and compared to the box body the same width frame are properly recorded. Here are the main benefits.

In the figures, a roller shutter box is shown, which receives in its interior only in Figs. 1 and 2 indicated roller shutter 1. The roller shutter shell 1 is supported by a telescoping roller shutter shaft 2 and can be wound up and unwound from this roller shutter shaft 2 in a known manner. The telescoping of the roller shutter shaft 2 is in the context of Representation and not limiting so achieved that the roller shutter shaft 2 of two telescoping hollow shafts 2a, 2b composed, which are fixed by means of a screw 3 or a similar locking device releasably against each other.

Furthermore, the illustrated shutter box a box body 4 and two the box body 4 laterally occlusive box end realized side covers 5, 6. The right in the illustration of FIG. 1 side cover 6 is used to support the hollow shaft 2b. In contrast, the left in Fig. 1 side cover 5 takes in the form of the winding side side cover 5, the hollow shaft 2a, which is formed axially displaceable relative to the relevant side cover 5.

In the variant according to FIG. 2, the left-hand side cover 6 in the representation there likewise serves to support the hollow shaft 2 b, whereas the hollow shaft 2 a penetrates the winding-side side cover 5. An associated telescopic device can be found in the representation of FIG. 1 in the area of the winding side side cover 5, while the variant of FIG. 2, the telescopic device in the region of the opposite side cover 6 arranges.

In order to achieve the telescoping of the roller shutter shaft 2, the hollow shaft 2a is inserted into the hollow shaft 2b. This makes it possible, on the one hand, to replace the roller shutter shell 1 from the interior of the box body 4 through an inspection opening in the bottom board 7. On the other hand, the telescoping of the roller shutter shaft 2 ensures that an outside of the box body 4 provided and connected to the shutter shaft 1 winding / unwinding 8 in the form of a belt reel 8 with a wound on it and merely indicated roller shutter 9 also inside spent the box body 4 and can be exchanged here. This is done in detail as follows.

With reference to FIGS. 1 and 3 it can be seen first that the box body 4 is adapted with its bottom board 7 of its length to a wall opening 11 receiving the shutter box together with a frame 10. That is, the shutter box is designed as Aufsetzkasten on the frame 10 and does not require special recesses within the wall opening 11. To connect the shutter box with the frame 10, the bottom board 7 has two legs 12, which clamp the upper frame legs between them. As a result, the roller shutter box can be used in conjunction with the frame 10 as a complete unit in the wall opening 11.

In the variant according to FIG. 1, the winding / unwinding unit or belt reel 8 is connected to the roller shutter shaft 2 with the interposition of a guiding / coupling device 13. Here, the coupling device 13 and not restrictive to a plug-in sleeve 13. In this case, the plug-in sleeve 13 is mounted in the winding-side side cover 5, which has a bearing opening 14 thereto. It can be seen that the winding / unwinding unit or belt reel 8 is connected in an axial extension to the roller shutter shaft 2 and is located outside of the box body 4 beyond the winding side side cover 5.

At the foot of the bearing opening 14 there are two pivot bearings 15, which cooperate with an outer peripheral side bearing ring 16 of the socket 13. In fact, the weight of the roller shutter 1 in conjunction with the roller shutter shaft 2 ensures that the plug-in sleeve 13 rests with its bearing ring 16 on the two pivot bearings 15. In addition, the bearing ring 16 rolls on the respective pivot bearings 15 in the winding side side cover 5 from. This happens when the take-up / unwinding unit or belt reel 8 is rotated (with the help of the roller shutter belt 9 or motor).

The plug-in sleeve 13 has, on the one hand, a plug-in insert 17 and, on the other hand, a stub shaft 18 as a plug-in pin (compare FIGS. 3 and 4). On the stub shaft 18, the up / unwinding or belt reel 8 is attached, while the plug insert 17, the roller shutter shaft 2 and there receives the hollow shaft 2a. Of course, instead of the plug insert 17, the stub shaft 18 could also be realized in the interior of the box body 4 for attaching the roller shutter shaft 2, whereas the up / unwinding unit 8 is inserted into an associated plug insert 17 outside the box body 4.

The stub shaft 18 extends coaxially in comparison to the roller shutter shaft 2, perpendicular to a stop flange 19 of the plug-in sleeve 13. The stop flange or stop ring 19 cooperates with a counter-flange 20 in the winding-side side cover 5. Two alternatives are shown in the exemplary embodiment and not restrictive. Usually, the two pivot bearings 15 represent the mating flange (solid line of reference number 20). But it is also possible that an alternative (or additional) counter-flange or counter-stop ring 20 is realized in the winding-side side cover 5, as indicated by dash-dotted lines. Either way, the stop flange or stop ring 19 experiences an axial fixation.

Of course, on the one hand, the roller shutter shaft 2 and / or on the other hand, the up / unwinding 8 also not pluggable with the plug-in sleeve or coupling device 13 are connected. Conceivable here are, for example, screw or rivet and Locking connections. For the sake of ease of assembly, however, you regularly accesses the plug receptacles 17, 18 back.

In fact, the hollow shaft 2a inserted into the plug-in insert 17 of the plug-in socket 13 ensures that the plug-in socket 13 and also the roller shutter shaft 2 are held axially. Because the hollow shaft 2a is fixed relative to the hollow shaft 2b by means of the screw 3. As a result, the stop flange 19 of the plug-in sleeve 13 is also positioned in comparison to the counter-stop flange 20 or counter-flange 20.

Now, if the roller shutter 9 is pulled or spring-assisted wound on the belt reel 8, the respective rotational movements of the belt reel 8 via the stub shaft 18 are finally transmitted to the roller shutter shaft 2 to raise or lower the roller shutter shell 1. This can also be done in such a way that the up / unwinding unit 8 is driven by a motor. Then the roller shutter belt 9 is missing.

In any case, the up / unwinding 8 is outside the Kastenköpers 4, and stored on the stub shaft 18 of the turn in the winding side cover 5 mounted plug-in sleeve 13. A only in Fig. 5 to be recognized cover 21 ensures that the roller shutter 9 and the belt reel 8 are protected from contamination. In addition, a belt guide, not shown, may be realized in the cover 21 to introduce the roller shutter belt 9 from outside the masonry in the cover 21 located inside. The belt guide can be screwed to the cover 21 and plastered in an opening to be closed in the masonry.

If, for example, the roller shutter shell 1 and / or the roller shutter belt 9 are exchanged and / or repaired, this is done through the open bottom board 7. This has a not explicitly shown Inspection flap. Since the roller shutter shaft 2 is made telescoping, the hollow shaft 2 a can be pressed into the hollow shaft 2 b and fixed by means of the screw 3. As a result, the hollow shaft 2a can be removed from the plug insert 17 of the plug-in sleeve 13 so that the roller shutter shaft 2 with the roller shutter shell 1 can be lifted out of the box body 4 as a whole. At the same time thereby falls away the axial support of the plug-in sleeve 13, which consequently can be conveyed together with the belt reel 8 through the bearing opening 14 in the side cover 5 into the interior of the box body 4 and revised.

A guide plate 22 for the roller shutter 1 is also removed. This is easily achieved because the guide plate 22 by means of pins 23 in the associated plug-in openings 24 of the respective side cover 5, 6 is held detachable. In addition, the guide letter 22 in conjunction with its pins 23 ensures that the two pivot bearings 15 are held in their axial position.

To accommodate the belt reel 8 including cover 21 in masonry, it is only necessary to provide in the area of the winding side cover 5 for a corresponding recess in the wall opening 11. Mostly you will install a suitable stone with recess here, the recess is closed by the previously mentioned plastered belt guide.

Comparable components and functionalities are used in the variant according to FIG. 2. However, here the guide / coupling device 13 does not receive the roller shutter shaft 2, but the roller shutter shaft is passed through this guide / coupling device 13, it consequently engages. As in the case of the plug-in sleeve 13, the guide / coupling device is mounted in the box-side realized winding side side cover 5, namely - As already described - with the help of the bearing ring 16, the two pivot bearing 15 and the stop flange 19. Instead of the plug insert 17 has the guide / coupling device 13 via a through hole 17 ', in which the shutter shaft 2 is inserted with its hollow shaft 2a and passed , Consequently, the roller shutter shaft 2 is equipped with an associated stub shaft 18 ', on which the up / unwinding or belt reel 8 - similar to the stub shaft 18 on the plug-in sleeve 13 - is plugged.

The assembly and disassembly succeeds as described above, because the guide / coupling device 13 can be moved in conjunction with the winding / unwinding 8 in the box interior by the hollow shaft 2a in the hollow shaft 2b - after optionally loosening the screw 3 - is inserted ,
