EP3705676B1 - Method for mounting a roller shutter box and roller shutter box mounted on a frame part - Google Patents

Description

field of technology

The invention initially relates to a method for assembling a roller shutter box according to the features of the preamble of claim 1.

The invention further relates to a roller shutter box placed on a frame part, such as a window or door frame, according to the features of the preamble of claim 4.

State of the art

Such methods and attached roller shutter boxes have already become known in various ways. The state of the art is referred to, for example EP 2 636 839 A2 referred.

The state of the art can be found further on EP 2 985 404 A1 to refer. In the method known from this, the roller shutter box is first placed on the frame part and locked with a holding part that is connected to the frame part. A static part is then threaded in and brought into a plug-in connection with an adapter strip. The static part has a form-fitting section for form-fitting interaction with the holding part. Due to the form-fitting section, it cannot be removed in a mere vertical upward movement. However, the static part must be inserted into the holder part in an angled orientation to achieve the positive locking position with the positive locking section, in order to then be lowered and be able to be connected to a bottom of the roller shutter box.

With regard to a roller shutter box placed on a frame part, the opening in the holding part only allows angled insertion with subsequent pivoting of the static part.

Next is the state of the art DE 10 2015 102 302 A1 , the DE 10 2018 106 423 A1 , the DE 20 2014101111 U1 and the EP 1 710 388 B1 to refer.

With the known methods and roller shutter boxes, there is still a need to achieve assembly that is as safe and easy to handle as possible. When the roller shutter box is inserted, the static part should be connected to the holding part as easily as possible.

Summary of the invention

Based on the prior art presented, the invention is concerned with the task of specifying a method for assembling a roller shutter box and a roller shutter box placed on a frame part, the method being intended to enable the simplest and safest possible installation of the roller shutter box using the static part. It is also an object of the invention to provide a roller shutter box with a holding part that is suitable for the simplest possible installation of the roller shutter box.

This task is solved with regard to the method in the subject matter of claim 1, the aim being that the static part is firmly connected to the roller shutter box before the roller shutter box is installed, that the roller shutter box with the connected static part is then snapped onto the holding part for installing the roller shutter box and that a positive connection is established between the static part and the holding part, so that the roller shutter box, after being placed on the holding part, moves into a displacement position in a longitudinal or transverse direction of the holding part is shifted and that the static part is assigned a blocking part by the displacement, which prevents the static part from being released from the positive connection in the displacement position when there is a load in a depth direction of the roller shutter box.

With regard to the roller shutter box placed on the frame part, the object of the subject matter of claim 4 is solved, with the aim being that the hindrance position is achieved by a blocking part acting at the installation location in the holding part, the static part being connected to the form-fitting section by vertical lowering when aligned of the form-fitting section can be inserted into the opening in accordance with the installation position and can then be moved into the hindrance position transversely to a longitudinal extent of the holding part.

According to the method, the static part, at least a lower part in the case of a two-part design of the static part, is already firmly connected to the roller shutter box before the roller shutter box is installed, that is to say in the given case it is locked with the holding part on the frame part.

The connection of the static part to the roller shutter box can be done, for example, by a screw connection, in particular a connection or screw connection to a base part of the roller shutter box.

With the static part installed in this way, the roller shutter box can be snapped onto the frame part in the usual way, while at the same time a positive connection can be established between the static part and the holding part. This form-fitting connection is preferably formed by a rear grip designed as an insert part, in particular as an insert tongue The positive locking section of the static part engaging the holding part is given, as seen in itself from what was already mentioned at the beginning EP 2 636 839 A2 is known. In contrast to the known prior art, however, the static part is not brought into this positive connection only after the roller shutter box has been snapped on, but at the same time as the roller shutter box is snapped on. The only vertical lowering that is possible at an installation location, which can be different from an installation location within the roller shutter box, makes it possible, even if the roller shutter box with the static part attached to it is inserted at a slight angle, at least in the last section of insertion to be able to move a horizontal plane and then reach the obstacle position at the end of this displacement path. In the hindrance position, the static part and thus the roller shutter box as a whole can no longer be moved transversely to a longitudinal extent of the holding part. The installation position can coincide with the insertion position of the roller shutter box, but it can also be the case that the insertion position is offset in a longitudinal direction of the holding part from the installation position and the roller shutter box with the static part attached to it, possibly also a static part alone (at least when dismantling) along a Longitudinal extension of the holding part can be moved, with the hindrance position then being reached (only) in the installed position.

The installation position is the position of the roller shutter box and the static part as it exists after completed assembly and corresponding to a usage position of the roller shutter box in relation to a longitudinal extent of the holding part.

The insertion position, on the other hand, refers to the position of the roller shutter box with the static part or the static part alone relative to the holding part, in which in the course of assembly or disassembly and in relation to a Longitudinal extension of the holding part, a first insertion of the static part or a final removal of the static part takes place. The holding part is usually attached to a top side of a frame part arranged in a building, with an opening that is open vertically at the top in this installation position.

With regard to the roller shutter box, which is placed on a frame part such as a window or door frame, it is intended in detail that at the given installation location of the roller shutter box there is an opening accessible from above and possibly laterally, which is used to introduce the corresponding positive-locking section, for example the insertion tongue, of the static part is used in the holding part, such a narrowing is made that in the event of a load to be absorbed by the static part in particular in a transverse direction of the roller shutter box, the static part cannot emerge from the positive connection. This narrowing of the opening, which is initially required in its larger extent for a desired production of the positive connection in the course of snapping on the roller shutter box, which is also preferably already connected to the static part in this embodiment, is achieved by a blocking part, preferably by a specially inserted one and, if necessary, a correspondingly attached blocking part. A different width of the opening is provided in a longitudinal direction of the holding part, so that by moving the roller shutter box into the installation position for the static part in the course of the process already described, the static part is released from the holding part when a load is placed in the depth direction of the roller shutter box is hindered.

The static part can be characterized by a slim design, viewed in an installed position in a longitudinal direction of a roller shutter box, which can also be advantageously manufactured cheaply. The static part preferably has a constant thickness over its entire extent transversely to this longitudinal orientation of the roller shutter box, i.e. in the end view described. In particular, in a preferred embodiment, there are no projections or the like that protrude beyond the surface plane with respect to the broad side surfaces viewed perpendicular to the longitudinal extent of the roller shutter box. On the other hand, recesses or even through openings are possible, for example to enable the static part to be attached.

In addition, a static part designed in this way also proves to be convenient in terms of handling, especially when it can be handled within a roller shutter box that is in the installed state, that is to say in a state placed on a frame part, for example for inspection purposes.

With regard to the holding part, the opening can be designed with different opening widths over the longitudinal extent. Such a holding part enables the different insertion position described here compared to the installation position and in particular also enables the obstacle position to be reached in the installation position.

Here, the different opening width can also be given by the fact that, in particular in the installed position, two opposite opening edges of the opening are only partially present, namely only in relation to one opening edge, here the opening edge facing the outside of the building in the installed position. In this respect, in this area of larger or infinite opening width, the roller shutter box can be pushed in with virtually no lifting or lowering.

There can be a combination of a holding part and a static part, in which the opening is designed with an opening width that enables the static part to be inserted by vertical lowering with an alignment of the form-fitting section corresponding to the installation position. In this respect, reference is also made to the further explanation with regard to the combination of the roller shutter box with the static part and the holding part described here. In accordance with the above-described possible design of the holding part, the holding part can also have an opening width over at least part of its longitudinal extent, which is, so to speak, infinite, in which only one opening edge is formed.

With regard to the combination mentioned, however, a holding part is also possible which has an opening that is significantly larger than an opening of previously known holding parts, has a larger opening width, namely such that it allows the described insertion of the static part from vertically above immediately at a Alignment of the form-fitting section according to the installation position. This opening can be designed to be the same throughout the length of the holding part. This is particularly the case if, as described in a possible embodiment, the static part is already equipped or provided with a blocking part.

According to a preferred embodiment, a static part with a uniform thickness viewed transversely to the wide surface extent of the static part can be formed in a single layer, for example by laser cutting.

Alternatively, the static part can also be formed in multiple layers, with the multiple layers being put together to form a layer package. Any location can for example, be punched. A connection can be made by stamping packages. A clamping or cohesion of package layers of a possibly lower static part can alternatively or additionally be provided in the area of a possible screw connection between the lower and an upper part, in particular an upper static part.

The static part can also be undeformed, preferably not having any projections or bends or the like formed from the resulting extension plane transversely to the thickness direction.

According to a preferred embodiment, the static part can have a thickness of 4 mm or more up to 10 mm or more, for example up to 15 mm or 20 mm. This thickness is preferably not exceeded at any point on the static part. Only in the area of a screw connection between an upper and a lower static part can the relevant thickness be exceeded, more preferably solely through the arrangement of screws or rivets or other connecting means.

Compared to the previously described (maximum) thickness of the static part, the static part can have zones of smaller thickness, for example in the area of depressions starting from a side or wide surface up to openings or the like. In particular, it is also preferred that the static part has one or more through openings which extend in the direction of a surface extent of the static part. Based on the installed condition, they preferably run vertically. In addition, the through openings are preferably assigned to a leg that is horizontal with respect to an installed state.

The through openings serve in particular to connect the static part, preferably before the roller shutter box is installed in a corresponding building opening, to the roller shutter box, specifically and preferably a roller shutter box base. The design of the same thickness also includes embodiments in which one or more functional parts are attached to the static part, for example the blocking part also described in this application and/or a separate fastening tab. It is preferred that the said static part of the same thickness also has this same thickness (maximum) in the area of the form-fitting section, although the functional part can be thicker as a separate part and can also include the static part in this area. In particular, it is preferred that the essential force absorption with regard to forces acting transversely to a longitudinal extent of the roller shutter box occurs practically only through the mentioned static part of the same thickness.

The design of the static part in the manner described with the same thickness transversely to a vertical extension makes it possible, in particular, to produce the static part inexpensively, for example by punching out or even cutting it out of a thicker sheet metal by, for example, laser cutting.

In one embodiment, the static part can be used with a thickness that is the same in relation to the installation position in a direction transverse to the vertical extension in both the horizontal and vertical legs for arrangement in a roller shutter box, with an opening provided from above at a given installation location of the roller shutter box of the holding part, through which the form-fitting section can reach the form-fitting receptacle, is narrowed in a depth direction of the roller shutter box in such a way that the static part can be released from the form-fitting connection in the displacement position is prevented when there is a load in the depth direction of the roller shutter box.

According to the method, the roller shutter box is moved into a displacement position in a longitudinal or transverse direction of the holding part after being placed on the holding part. This makes it possible in a simple manner to provide different configurations in the holding part with a view to interacting with the static part, with a configuration given in the displacement position, which then corresponds to the installation position, being designed to release the static part from the positive connection at a To prevent loading in a depth direction of the roller shutter box. In an alternative embodiment, the design that creates the obstacle in the displacement position can also be part of the roller shutter box or the static part. With the sliding displacement, the design can be moved into a position that creates the desired obstacle.

The positive connection is preferably provided as a grip between a free end of the static part and the holding part.

The setting of the displacement position, preferably the underhand grip, is further achieved by a blocking part attached to the holding part, alternatively to the static part, or assigned to the static part by the displacement. The blocking part serves to narrow the free space of the opening for the static part or for the positive-locking section of the static part, which is in positive engagement with the holding part, in the load direction to be taken into account, that is, in the transverse direction of the roller shutter box.

The static part can be displaced from the latching position, which corresponds to the insertion position, in the direction of the displacement position mentioned in the longitudinal direction of the roller shutter box and/or the mounting part. In particular, the holding part can provide rail-like guidance for the static part and, through it, the roller shutter box connected to the static part in the course of the sliding displacement.

With the above-described sliding displacement, in particular the static part is brought into a position relative to the holding part, in which position the prevention of displacement of the static part transversely to the direction of displacement is ensured by appropriate measures on the holding part or by appropriate measures on the static part.

According to a further possible embodiment, the static part (together with the roller shutter box) can be displaced transversely to the longitudinal extent of the holding part in order to be moved from the latching position into the displacement position, with a blocking part to be arranged at the rear when viewed in the sliding direction being provided during or upon completion of this sliding displacement into an underhand position in order to prevent the static part from shifting backwards in the load direction to be observed, thereby removing the underhand grip.

The narrowing of the opening can be achieved by a blocking part to be arranged separately or by a blocking part connected to the static part. This blocking part can be provided before and/or in the course of assuming the latching position of the static part in a ready position, for example on the static part, from which ready position in the latching position of the static part the blocking part can be moved into the blocking position that reaches the narrowing of the opening.

According to a possible embodiment, the blocking part can be attached to the static part in a vertically displaceable manner. From a standby position, the blocking part can be lowered vertically, for example, in the locked position of the static part, in order to narrow the opening in the holding part.

The blocking part can be moved manually from the standby position to the blocking position. The blocking part can also be moved into a blocking position by its weight. According to a further possible embodiment, the blocking part can be spring-biased into the blocking position, for which purpose, for example, a spring, for example a compression spring, which loads the blocking part in the direction of the blocking position and is supported at the other end on a section of the static part, can be provided. As a result of such a possible configuration, possibly due to the weight alone, the blocking part is suitable for automatically lowering into the blocking position like a trap when the static part reaches the latching position.

In order to remove the blocking position, for example to dismantle the static part with the roller shutter box in place, in such a design the blocking part must be lifted manually against the force of the spring.

As described above, the blocking part can be used separately in the holding part, in a position that narrows the opening, and can be fastened there, for example by means of a screw connection. Such positioning of a blocking part in the holding part can be done, for example, on site, immediately before installing the roller shutter box on the frame part.

In a further embodiment, the blocking part can also be an integral part of the holding part as a whole. According to a possible embodiment, the opening can be designed according to the required narrowing, with an installation recess on the holding part being formed on the side of the (narrowed) opening - viewed in the longitudinal extent of the attached roller shutter box - which allows the static part to be inserted from vertically above and a subsequent displacement of the static part transversely to a longitudinal extent of the holding part into a positive locking position.

With regard to the opening width viewed transversely to the longitudinal extent, the holding part can initially basically have the required narrowing over a preferably largest part of the longitudinal extent. For attaching and locking the static part, at least one installation recess is provided, in the area of which the opening is enlarged transversely to the longitudinal extent of the holding part at least to such an extent that the static part is inserted from vertically above and can be brought into the locking position by sliding transversely to the longitudinal extent of the holding part, after which then a sliding displacement in the longitudinal direction of the holding part into the blocking position can be carried out.

Several such installation recesses can be provided on the holding part, for example two, three or more such installation recesses distributed evenly or unevenly over the length. The number and arrangement of installation recesses can be adapted to the number and positioning of static parts provided.

According to a possible embodiment, the installation recess can be made by appropriately cutting out an area of an otherwise in Longitudinal extension direction continuous, provided with a narrowed opening mounting part profile. In such a free-cutting area, the opening only has one opening edge, which is the opening edge of the holding part that is assigned to the outside of the housing during normal installation.

The static part can also have a fastening formation with a penetration opening for a fastener that extends in the direction of the horizontal leg when installed. The fastening formation can be designed for possible contact with an optionally given shoulder of the roller shutter box, for example in the area of the base part, in particular the fixed base part. According to a possible embodiment, a stop can be provided via the fastening formation, which limits a sliding displacement of the static part transversely to the longitudinal extent of the roller shutter box. The stop position can, as is further preferred, be the position in which an optionally present blocking part can be moved into a blocking position by weight, possibly spring-loaded.

In this installed state (locking state), the installed position, the static part can be fixed to the roller shutter box, in particular to a bottom part of the roller shutter box, via a fastening means, for example in the form of a screw (unless it has already been connected to the roller shutter box during assembly). was). In a preferred embodiment, this fastening means passes through the fastening formation in the area of a penetration opening and engages in a roller shutter box section, in particular in a section of the roller shutter box base part.

In addition, a locking projection can be formed in the direction of the horizontal leg at a distance from the fastening formation, for locking the static part on the roller shutter box. According to a possible embodiment, the locking projection can point from the horizontal leg in the same direction as the above-described fastening formation, so further in the usual orientation of the static part downwards.

The locking projection and the fastening formation can also be designed in one piece and of the same material with the static part, and, as is also preferred, have the same thickness as the static part.

A section of the roller shutter box, for example a section of the fixed base part, can be caught between the locking projection and the fastening formation, with a section of the locking projection engaging under a counter section of the roller shutter box or the base part in such a way that a locking fixation prevents a relative displacement of the static part with respect to the Roller shutter box part having counter-locking area is prevented from moving vertically upwards.

In a static part of the type in question, the static part is composed of an upper static part and a lower static part, the lower static part being designed for attachment to the frame part and the upper static part for connection to a building ceiling part, to solve the problem It can be provided that the upper static part has two connecting legs that are spaced apart in the horizontal direction relative to the installation position for connection to the lower static part and that the connecting legs are of different lengths in the vertical direction.

Thanks to the connecting legs of different lengths, a favorable assembly and disassembly, in particular of the lower static part in the roller shutter box, can be achieved. The connecting legs of the lower static part to be connected to the connecting legs of the upper static part can, as is also preferred, be adapted in length to the previously described lengths of the connecting legs of the upper static part, with a connecting leg and an assignable connecting leg of the upper static part together forming the vertical leg of the static part as a whole .

After releasing a connection between the lower static part and the upper static part, this can result in a sliding displacement option for the lower static part relative to the upper static part, with a shorter connecting leg of the lower static part being able to pass under the shorter connecting leg of the upper static part.

Connecting means provided on the connecting leg for connecting the upper static part to the lower static part can be provided in the installed state in the horizontal direction without overlapping one another.

Overall, this also results in a design of the static part that is favorable in terms of handling.

Description of the embodiments

Shown and described is a schematic and partially shown roller shutter box, which is related to Figure 1 in the exemplary embodiment shown has a ceiling part 2, a front wall 3, a floor part 4, a floor inspection part 5 and a rear wall 6.

In the roller shutter box 1, which is assembled from the parts mentioned in a workshop for later installation in a building, on a frame part 16 such as a window or door frame, a static part 7 is arranged, with predominantly only a lower part in the figures The exemplary embodiments are preferably shown in two-part static part. The static part 7 can further have an upper part which can extend up to the ceiling part 2 or, as is preferred in the context of the present application, beyond the ceiling part 2, passing through an elongated hole opening in the ceiling part 2. Such an upper part is at least partially designed as an upper static part 29 in Figure 20 shown. It preferably has a connection area above the uppermost area of the parts shown, so that the upper part is also an upper static part that can be handled in a uniform manner.

According to the preferred method for assembling the roller shutter box, the static part 7 is already connected to the base part 4 before the in Figure 1 Installation position shown connected, in the exemplary embodiment by fixing screws 8, 9, which, in the case of a static part 7 designed, for example, as a bent sheet metal part, pass through a fastening leg 17 which is aligned, for example, essentially parallel to the base part 4.

The static part 7 passes through a recess 10, which is also preferably formed in the base part 4, and protrudes with a form-fitting section 11, here designed as a tongue-like engagement projection, compare in particular Figure 3 , through the base part 4. The form-fitting section 11 (engagement projection) can in particular be in the horizontal direction in the exemplary embodiment (relative to an installation position, such as in Figure 4 is shown) can be formed with an angled insertion nose. In the assembled state of the roller shutter box, this form-fitting section 11 can engage behind an engagement recess 12 formed in a holding section 19 of the holding part 13 of the holding part 13 attached to the frame part, compare in particular Figure 2 , serve. The engagement recess 12 is also referred to above and below as a form-fitting receptacle.

This rear grip also prevents the roller shutter box from being lifted out vertically together with the connected static part. A significant stress on such a roller shutter box 1 when installed, see in particular Figure 3 , but is in a depth direction T, although this can of course also be the case in the opposite direction depending on the suction load or wind pressure load.

The roller shutter box 1 prepared in this way is, as in Figure 3 shown, in a first position, a latching position S1, which is also referred to above and below as an insertion position, latched with the holding part 13 and then in a second position, a displacement position S2, which is forward and Also referred to below as the installation position, shifted (in sliding direction a). The roller shutter box 1 with the connected static part 7 can be brought into the latching position by practically simply lowering it vertically and then moving it transversely to a longitudinal extent of the holding part 13. In the latching position S1, which is also referred to as the insertion position, the roller shutter box 1 with the static part 7 or possibly the static part 7 alone is already clearly pushed forward, but could still be brought back into a position in the depth direction T by moving it back in which it can be removed vertically upwards.

The prepared roller shutter box 1, i.e. the roller shutter box 1 connected to the static part 7, is preferably positioned in such a way that the area of the static part 7 having the positive locking section 11 is lowered essentially from vertically above through the opening 15, which is correspondingly widened transversely to the longitudinal extent of the holding part 13 is, after which, for the positive engagement of the positive-locking section 11 in the engagement recess 12 of the holding part 13, the roller shutter box 1 is displaced together with the static part 7 (or with the several static parts 7) transversely to the longitudinal extent of the holding part 13 (essentially in the direction of the outside of the building).

In this vertical placement, the procedure can in particular be such that the form-fitting section already has an orientation that also exists in the installed position, here given as the displacement position S2.

From the insertion position S1, the insertion position, takes place accordingly in the Figures 1 to 6 and 7 to 9 In the embodiments shown below, a sliding displacement in the direction of arrow a into the displacement position S2, in which displacement position S2 is transverse to the longitudinal extent The width b of the opening 15 considered by the holding part 13 is reduced in such a way that a support is achieved at the rear of the area of the static part 7 having the positive locking section 11, which prevents the static part 7 from being displaced back, thereby eliminating the positive connection between the positive locking section 11 and the engagement recess 12.

In the in the Figures 1 to 6 The first embodiment shown is in the displacement position S2 of the roller shutter box 1, which can also correspond to the installation and use position, as shown in particular Figure 2 can be seen, a blocking part 14 is inserted into the holding part 13. It can be screwed to the holding part 13 or connected in some other way. This shows a width b of the opening 15 or displacement recess or displacement recess 18 of the holding part 13 in the displacement position S2 compared to the width in the latching position S1 (compare Figures 5 and 6 ) is narrowed in such a way that the static part 7 located in the form-fitting connection to the holding part 13 cannot move out of the form-fitting connection in the depth direction. As described, a vertically upward blockage is, as described, preferably provided anyway by the interaction of the engagement projection and the engagement recess 12.

In the event that it becomes necessary to remove the static part 7, for example if a roller shutter box shaft with a roller shutter box armor is to be removed, the static part 7 can be detached from the roller shutter box 1, here by loosening a screw connection with the base part 4, and then within the holding part 13 can be moved from the displacement position S2 into the locking position S1 in accordance with the displacement of the roller shutter box as a whole, but now only based on the static part 7, during installation, as indicated by the recess 10 provided for this purpose in the base part (see Figure 4 ). The recess 10 is in Longitudinal extension of the holding part 13 viewed on the displacement path from a locking position S1 into the displacement position S2 and back adapted in the form of an elongated rectangular or oval opening. Then the static part, in the given exemplary embodiment the lower part of the static part 7, can be swung out and removed in the usual way, without the need for the entire roller shutter box 1 to be moved (back) into the latching position S1.

The blocking part 14 as well as the holding part 13 are preferably designed as metal parts, for example sheet metal parts, in particular with regard to the holding part 13. Further details of the holding part 13 and its connection to the frame part 16 can also be found on the EP 2636839 A2 and the EP 1710388 B1 to get expelled. The same applies to the German patent application 10 2018 106 423 referred.

According to the method described here, the following procedure can now be followed when installing a roller shutter box 1.

The roller shutter box 1 is initially assembled in a workshop, usually outside of a building in which it is ultimately to be installed, with regard to some or all of the parts in relation to Figure 1 are described. In addition, the static part 7 is installed and firmly connected to the roller shutter box 1 produced in this way, that is to say it can be handled in a uniform manner for installation with the roller shutter box 1.

The explanations continue in accordance with Figures 1 to 6 and 7 to 9 determined at which point, based on a width of the frame part 16, one or more of the static parts 7 should be located in the final installed state of the roller shutter box 1 in the displacement position S2. In view of this is according to the in the Figures 1 to 6 In the first exemplary embodiment shown, the holding part 13 is provided with the blocking part 14 at the relevant location or locations. For this purpose, the blocking part 14 is preferably screwed to the holding part 13 at the relevant point.

This holding part 13 prepared in this way is then firmly connected to the frame part, preferably also by screwing. If necessary, one or more blocking parts 14 can only be attached to the holding part 13 after such a connection of the holding part 13 with the frame part.

The Figures 7 to 9 show an embodiment in which the blocking part 14 is essentially an integral part of the holding part 13.

The holding part 13 is initially and essentially designed in such a way that, with respect to the opening 15, there is basically a narrowing in accordance with the above-described exemplary embodiment in the area of the arranged blocking part 14.

Viewed in the longitudinal extent of the holding part 13, an installation recess 20 is formed on the holding part 13 laterally, preferably on both sides, of a section of the holding part 13 that forms the blocking part 14. In the area of these installation recesses 20, the expanded width of the opening 15, which enables the vertical insertion of the area of the static part 7 having the form-fitting section 11, is as shown in Figure 8 given. The installation recess 20 can be formed by cutting out a blocking section from the holding part 13. The opening 15, which otherwise and at least in the installed position, has two opening edges is formed, can, as shown, be formed in the area of the installation recess 20 only with an opening edge.

In this embodiment too, the prepared roller shutter box 1 with the static part 7 is first placed in the area of the installation recess 20. After assuming the form-fitting position between the form-fitting section 11 and the engagement recess 12 of the holding part 13, the roller shutter box 1 is displaced together with the static part 7 from the latching position S1 in the sliding direction a into the displacement position S2 (see also Figures 7 to 9 ).

Viewed in the longitudinal direction of the holding part 13, in this embodiment the displacement position S2 of the static part 7 can be assumed essentially freely between two installation recesses 20 which follow one another in the longitudinal direction of the holding part 13.

Such limited variability with regard to the displacement position S2 can also be achieved with a separately provided blocking part 14 according to the one shown in FIG Figures 1 to 6 The first exemplary embodiment shown can be given by a correspondingly selected extension of the blocking part 14 in the longitudinal direction.

Furthermore, the roller shutter box 1 prepared as described can be placed in an obliquely raised position on the holding part 13 and moved slightly forward, i.e. towards the outside of the house, and then lowered. This results in the engagement of the form-fitting section 11 of the static part 7 in the corresponding area of the holding part 13 and the locking of corresponding parts of a base part 4 of the roller shutter box 1 with the holding part 13.

The roller shutter box 1 placed in this way is then moved in a longitudinal direction of the holding part 13 in the sliding direction a into the described displacement position S2.

With regard to a hindrance of the static part 7 in the displacement position S2, or the installation position, from a significant movement transversely to a longitudinal extent of the holding part, be it by the blocking part or a mere narrowing of the opening, the hindrance position mentioned above and below is given.

The static part 7 can then be firmly connected in an upper area to a building wall, possibly a lintel of a window opening. If the static part 7 is designed in two parts, the connection can also be made first to the lower part, which is already connected to the roller shutter box 1 in the manner described when it is inserted. The upper part can also be connected to the lower part when it is inserted.

Because an upper and a lower part, which are connected to one another, for example by screws, are preferably provided with respect to the static part 7, this lower part can be removed if the static part 7 is possibly required to be removed, with removal of the lower part generally being sufficient detach from the upper part and remove it in the manner described by lateral displacement against the sliding direction a from the displacement position S2 and thus also remove it from the blocking part 14, so that it is moved into an area in which it can then easily be angled upwards can be lifted out and removed from the roller shutter box 1. The position of the static part 7 achieved here relative to the holding part 13 can be the locking position S1 described. Then there is a sufficient one Working opening is given, if necessary after removing the floor inspection part 5, in order to be able to remove the roller shutter curtain and / or a drive shaft of the roller shutter curtain from the roller shutter box 1.

The Figures 10 to 15 show a further embodiment in which the blocking part 14 is attached to the static part 7 in a vertically displaceable manner. Accordingly, the blocking part 14 according to this embodiment is part of the static part 7.

The blocking part 14 is arranged on the static part 7 in such a way that, in the usual installation situation of the static part 7 or the roller shutter box 1, it can be displaced in the vertical direction relative to the static part 7.

In this case, the blocking part 14 can, as is also preferred, be arranged on a leg 21 which is essentially horizontally oriented in the installation situation, essentially to the rear of the form-fitting section 11, the horizontal leg 21 giving the blocking part 14, which in the exemplary embodiment is forked in a fork-like manner, surrounding this horizontal leg 21, a guide in the vertical direction.

The blocking part 14 can be spring-biased towards a blocking position. For this purpose, a compression spring 22 can be provided, which is supported on the horizontal leg 21 of the static part 7 and has a loading effect on the blocking part 14 (see also the sectional views in the Figures 11 and 14 ).

In this embodiment, in order to achieve the blocking of the static part 7 in the transverse direction, as described, it is not necessary to shift it Static part 7 together with the roller shutter box 1 in the longitudinal direction of the holding part 13.

Rather, the roller shutter box 1 together with the static part 7 is first inserted in the usual manner from vertically above through the opening 15 of the holding part 13, which has the expanded width b, in the direction of the sliding recess 18. This provides support for the blocking part 14 arranged on the static part 7 a leg 23 delimiting the opening 15 opposite the holding section 19, this is achieved under appropriate tension of the compression spring 22 (see illustrations in the Figures 10 and 11 ).

By subsequently sliding the static part 7 in the direction of arrow c (see Figure 13 ), as is also common in the above-described exemplary embodiments for bringing about the positive engagement, the positive locking section 11 is displaced into the engagement recess 12. The blocking part 14, which is simultaneously dragged along in the direction of arrow c, loses the support on the leg 23 in the course of this sliding displacement, as a result of which the blocking part 14 is affected by the compression spring 22 and / or the weight force as shown in the Figures 13 to 15 falls into the blocking position, in which the blocking part 14, sitting on the displacement recess 18, narrows the width b of the opening 15 in such a way that the static part 7 can be prevented from moving back against the direction of the arrow c.

In this embodiment too, the static part 7 is preferably screwed to the roller shutter box 1, in particular to the base part 4. For this purpose, the horizontal leg 21 has through openings 24, for example bores, for fixing screws, which pass through the horizontal leg 21 in the vertical direction 8, 9 on. Alternatively, a clamp or the like spanning the horizontal leg 21 can also be screw-connected to the base part 4.

To remove a static part 7 of the above-described embodiment from a built-in roller shutter box 1, after loosening the screw fastening with the base part 4, the blocking part 14 is manually moved vertically upwards against the force of the compression spring 22 into a position that releases the entire width b of the opening 15, after which the Statistical part 7 can be removed in the usual way.

The static part used in this embodiment can be a static part according to that shown in FIGS Figures 16 to 19 be the exemplary embodiment shown. Such a static part 7 can also be used in the other embodiments according to Figures 1 to 9 find use.

The statics part 7 of the embodiment in the Figures 16 to 19 (also in accordance with the Figures 10 to 15 ) is essentially composed, with reference to a vertical installation position, of horizontal legs 21 and vertical legs 25 arranged at a 90 degree angle in a side view, with the horizontal leg 21 associated with its free end forming the form-fitting section 11.

The form-fitting section 11 is, for example, in the side view in Figure 17 can be seen, formed in a plane offset vertically from the horizontal leg 21 and connected to the horizontal leg 21 via a substantially vertically extending bridging section 26.

In a direction R transverse to the vertical extension, the static part 7 including the form-fitting section 11 has a constant thickness d. This thickness d can, as is also preferred, be 5 to 15 mm, more preferably about 10 mm.

The horizontal leg 21 and the vertical leg 25 and beyond that the form-fitting section 11 with the bridging section 26 are preferably formed in one piece and of the same material. For example, the static part 7 is manufactured using laser cutting.

The static part 7 can be made in one layer, as shown. Furthermore, the static part 7 is undeformed and accordingly does not have any outwardly projecting or rejecting bends or projections from the family of planes resulting in the thickness direction.

In the area of the vertical leg 25, recesses 27 can be provided, for example for the passage of fastening screws 28, for example by cutting free. An upper static part 29 can be attached here, via which upper static part 29 a connection to a building ceiling part can be achieved.

In this case, the upper static part 29, together with the static part 7 designed as a lower static part 30, forms an overall static part 31. The upper static part 29 is preferably also connected to a connecting section, not shown here, between the legs shown, so that it also forms a uniform static part is manageable on its own.

As also in connection with the exemplary embodiment Figures 10 to 15 explained, but also in the embodiment of Figures 16 to 19 shown, the horizontal leg 21 can have through openings 24 aligned perpendicular to its longitudinal extent, for example in the form of bores.

Through the through openings 24, two of which can be provided one behind the other in the longitudinal direction of the horizontal leg 21, fixing screws 8, 9 can be inserted for screw fastening the static part 7 or the entire static part 31, for example to a base part 4 of a roller shutter box 1.

Figure 21 shows a further embodiment of a lower static part 30 formed in one piece with the same thickness with a blocking part 14, which is preferably resiliently supported on the horizontal leg 21, according to the figure shown in FIG Figures 10 to 15 illustrated embodiment.

The attachment of the lower static part 30 to the roller shutter box 1, in particular to its base part 4, is also achieved here using a screw connection. For this purpose, the horizontal leg 21 has a downwardly projecting fastening formation 34 when installed. This projection-like fastening formation 34 is preferably formed in one piece and of the same material with the horizontal leg 21, more particularly with the entire lower static part 30, here preferably having the same thickness d as the remaining lower static part 30.

In the allocation position according to Figure 21 The fastening formation 34 can rest against a back surface of the base part 4 facing away from the engagement recess 12 of the holding part 13 in a stop-limiting manner. In this contact position, a fastening means 36, for example in the form of a screw, in particular a self-tapping screw, can be used, if necessary after removal of the floor inspection part 5, can be screwed into the floor part 4 through an opening 35 in the fastening formation 34. In this screwing position, the fastening means 36 extends essentially in the extension direction of the horizontal leg 21.

After screwing has been completed, the floor inspection part 5 can be attached or snapped into place.

In a further embodiment, a locking projection 37 can be formed on the horizontal leg 21 with a given spacing in the extension direction of the horizontal leg 21 from the fastening formation 34. In the fixing position, the locking projection 37 engages under a counter-locking section 38 of the base part 4 (see enlarged illustration in Figure 21 ).

Due to the above-described arrangement and design of the locking projection 37 and the fastening formation 34, a positive holding of the lower static part 30 on the roller shutter box 1 can be achieved. This positive locking position can be secured via the fastening means 36.

In the representation in Figure 20 Based on a further embodiment, an overall static part 31 is shown, which essentially has two vertical legs 25 that are spaced apart in relation to the installation position in the horizontal direction or in the longitudinal direction of the holding part 13 or the roller shutter box 1.

For this purpose, the lower static part 30 or the static part 7 can have correspondingly spaced, vertically aligned connecting legs 32. These can have the recesses 27 described above.

The connecting legs 32 can be connected to one another via a fastening leg 17 which extends between them on the foot side and essentially forms the horizontal leg 21, which fastening leg 17 can form the positive-locking section 11 in the area of its free end.

The connecting legs 33 of the upper static part 29, which are also spaced apart from one another, are connected in the usual position of use via fastening screws 28 to the connecting legs 32 of the lower static part 30 and are spaced apart from one another in accordance with the connecting legs 32.

Furthermore, the connecting legs 33 have different lengths l and l 'when viewed in the vertical direction. The relevant vertical lengths of the connecting legs 32 of the lower static part 30 are adapted to the lengths of the connecting legs 33, so that a longer connecting leg 33 with a length l has a shorter connecting leg 32 with a vertical length m 'and the connecting leg 33 with the shorter length l' a connecting leg 32 with a greater length m are assigned.

The lengths l, l' or m, m' are chosen so that after loosening the fastening screws 28 for sliding displacement of the static part 7 or the lower static part 30 out of the displacement position S2 in the direction of the latching position S1 of the connecting leg 32 of shorter length m' In the course of the displacement, it can be passed under the connecting leg 33 of shorter length l 'of the upper static part 29.

The added total length of the connecting and connecting legs of shorter lengths l', m' is less than the total vertical length p of the vertical leg 25.

The connecting means V (fastening screws 28 and/or recesses 27) provided on the connecting legs 33 for connecting the upper static part 29 to the lower static part 30 are provided in the installed state in the horizontal direction without overlapping one another, and are accordingly projected in a common vertical plane, preferably in the vertical direction Side by side spaced apart. <b>List of reference symbols</b> 1 Roller shutter box 28 Fastening screw 2 ceiling part 29 Upper static part 3 front wall 30 Lower static part 4 bottom part 31 Total statics part 5 Floor inspection part 32 connection leg 6 Back wall 33 connecting leg 7 statics part 34 Fastening formation 8th Fixing screw 35 Enforcement opening 9 Fixing screw 36 Fasteners 10 recess 37 locking projection 11 Form-fitting section 38 Counter-locking section 12 engagement recess 13 Bracket part a Sliding direction 14 Blockade part b Width 15 opening c Sliding direction 16 frame part d thickness 17 Fastening leg l length 18 Displacement depression l' length 19 Bracket section m length 20 Installation recess m' length 21 Horizontal leg p Vertical length 22 Compression spring R Direction 23 leg S1 Locking position 24 Passage opening S2 Shift position 25 vertical leg T Depth direction 26 bridging section v lanyard 27 recess
