The invention also relates to a roller shutter box placed on a frame part, such as a window / or door frame, the roller shutter box having a static part which engages in a mounting part attached to the frame part and acts directly between the mounting part and a building wall, the mounting part also has a form-fit receptacle for a form-fit section of the static part and the static part is thereby prevented in an installation position from moving with respect to the form-fit section in any case vertically upwards and at a given installation location of the static part an opening of the mounting part given from above through which the form-fit section enters the form-fit seat can, is narrowed in a depth direction of the roller shutter box in such a way that there is a hindrance position in which a release of the form-fit section from the form-fit receptacle in the event of a load in the depth direction of the roller shutter joint astens is prevented.

In addition, the invention relates to a static part for connecting a frame part, such as a window or door frame, to a building wall, preferably enforcing a roller shutter box, the static part having a vertical extent in relation to an installation position, it extending from vertically below, assigned to the frame part, to vertically above, assigned to the building wall, and having a form-fitting section for connection to the frame part.

In addition, the invention relates to a mounting part for attachment to a frame part, such as a window or door frame, wherein the mounting part can serve to mount a roller shutter box on the frame part, the mounting part also having a longitudinal extension, an opening corresponding to the longitudinal extension and a form-fit receptacle.

Finally, the invention also relates to a combination of a mounting part for attachment to a frame part, such as a window or door frame, wherein the mounting part can serve to hold a roller shutter box on the frame part, and a static part, wherein the static part has a form-fitting section, the The mounting part has a longitudinal extension, an opening running corresponding to the longitudinal extension and a form-fit receptacle, and the static part with the form-fit section is received in the form-fit receptacle in an installation position.

State of the art

Such methods and roller shutter boxes and parts are already known in various ways. For the state of the art, for example EP 2 636 839 A2 referenced.

For the state of the art, refer to the EP 2 985 404 A1 to refer. In the method known from this, the roller shutter box is first opened placed on the frame part and locked in place with a mounting 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-fit section for form-fit interaction with the mounting part. As a result of the form-fit section, it cannot be removed in an upward vertical movement. The static part must, however, be inserted into the mounting part in an angled orientation in order to achieve the form-fit position with the form-fit section, so that it can then be lowered and 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 mounting part allows only an angled insertion with subsequent pivoting of the static part.

The static part known from the cited prior art is also designed as a bent sheet metal part, with a beveled lower horizontal limb and a vertical limb that protrudes from it.

Further to the state of the art, refer to DE 10 2015 102 302 A1 , the DE 10 2018 106 423 A1 , the DE 20 2014 101 111 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 easy to handle as possible. With the insertion of the roller shutter box, a connection between the static part and the holding part should be given 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, the method being intended to enable the roller shutter box to be installed as simply and safely as possible using the static part. Another object of the invention is to specify a roller shutter box with a mounting part, suitable for the simplest possible installation of the roller shutter box. In addition, the object of the invention is to design a static part of the type in question with continued stability, particularly in terms of production engineering.

This object is achieved first and foremost with regard to the method in 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 mounting part for installing the roller shutter box and that a form-fit connection between the static part and the bracket part is produced.

With regard to the roller shutter box, the object is achieved in the subject matter of claim 6, the aim being that the static part with the form-fit section can be inserted into the opening by vertical lowering when the form-fit section is aligned in accordance with the installation position and then into the obstructing position transversely to a longitudinal extension of the mounting part is relocatable.

With regard to the static part, the object is achieved in the subject matter of claim 14, the aim being that the static part is designed with the same width in an end view which only reveals the vertical extent, including the form-fit section.

According to the preferred method, the static part, at least one 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 it is latched to the mounting part on the frame part in the given case.

The static part can be connected to the roller shutter box, for example, by a screw connection, in particular a connection or screw connection to a bottom 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 a conventional manner, and at the same time a form-fit connection can be established between the static part and the mounting part. This form-fit connection is preferably provided by a form-fit section of the static part which is designed as a plug-in part, in particular as a plug-in tongue and engages in a grip behind the mounting part, as seen in isolation from the above-mentioned EP 2 636 839 A2 is known. In contrast to the known prior art, however, the static part is not brought into this form-locking 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 possible vertical lowering that is achieved at a place of insertion, which can be different from a place of installation within the roller shutter box, makes it possible, even if the roller shutter box with attached static part is inserted at a slight angle, but at least in the last section of the insertion to be able to move a horizontal plane and then to reach the hindrance 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 displaced transversely to a longitudinal extension of the mounting part. The installation position can match the insertion position of the roller shutter box coincide, but it can also be the case that the insertion position is offset in a longitudinal direction of the mounting part from the installation position and the roller shutter box with attached static part, possibly also a static part alone (at least when removing), can be moved along a longitudinal extension of the mounting part, the hindrance position is then (only) reached in the installation position.

The installation position is the position of the roller shutter box and of the static part as it is present after completion of assembly and corresponding to a use position of the roller shutter box in relation to a longitudinal extension of the mounting part.

The insertion position, on the other hand, denotes that position of the roller shutter box with the static part or the static part alone relative to the mounting part in which the static part is first inserted or the static part is finally removed in the course of assembly or disassembly and based on a longitudinal extension of the mounting part. The mounting part is usually fastened to an upper side of a frame part arranged in a building, with an opening that is vertically open 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, the focus is on the fact that at the given installation location of the roller shutter box, an opening accessible from above and / or from the side, which is used to introduce the corresponding form-fit section, i.e. For example, the insertion tongue of the static part is used in the mounting part, such a narrowing is made that in the event of a load in a transverse direction of the roller shutter box that is particularly to be absorbed by the static part, the static part does not come out of the positive connection can step out. This narrowing of the opening, which is initially necessary in its larger extent for a desired production of the form-fitting connection in the course of a snapping on of the roller shutter box, which is also preferably already connected to the static part in this embodiment, is preferably provided by a specially inserted and possibly appropriately attached Blocked part reached. However, the solution already mentioned in principle can also be given that a different width of the opening is provided in a longitudinal direction of the mounting part, so that by shifting the roller shutter box into the installation position for the static part in the course of the process already described, a Solution of the static part from the bracket part is prevented when a load in the depth direction of the roller shutter box.

The proposed static part is characterized in particular by a slim design, viewed in an installation position in a longitudinal direction of a roller shutter box, which can also be advantageously manufactured in an advantageous manner. In this case, the static part preferably has a constant thickness over its entire extension transversely to this longitudinal orientation of the roller shutter box, that is to say in the end view described. In particular, in a preferred embodiment, there are no projections or the like protruding beyond the plane of the surface with respect to the broad side surfaces viewed perpendicularly to the longitudinal extension of the roller shutter box. In contrast, 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 advantageous in terms of handling, in particular in the case of possible handling within a built-in state, that is to say in a on a frame part mounted state located roller shutter box, for example for inspection purposes.

With regard to the mounting part, the invention is based on the fact that the opening is formed with a different opening width over the longitudinal extent. Such a mounting part enables the different insertion position described here in relation to the installation position and, in particular, also enables the obstructing position to be reached in the installation position.

Here, the different opening widths can also be given by the fact that two opposite opening edges of the opening are only partially given, especially in the installation position, namely only in relation to one opening edge, here the opening edge facing the outside of the building in the installation position. In this respect, the roller shutter box can be pushed in practically without raising and lowering in this area of greater or infinite opening width.

With regard to the combination of a mounting part and a static part, the aim is that the opening is formed with an opening width that enables the static part to be inserted by lowering it vertically when the interlocking section is aligned according 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 mounting part described here. Corresponding to the previously described possible configuration of the mounting part, the mounting part can also in this context have an opening width over at least part of its longitudinal extent which is infinite, so to speak, in which only one opening edge is formed.

With regard to the combination mentioned, however, a mounting part is also possible and in this respect also has an independent meaning that an opening which is significantly larger than an opening of previously known mounting parts has a larger opening width, namely such that it enables the described insertion of the static part from vertically above immediately with an alignment of the form-fit section according to the installation position. This opening can be of the same design throughout the length of the holding part. This is particularly the case when, as also described according to 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 broad area of the static part can be formed in one layer, for example as a result of laser cutting.

Alternatively, the static part can also be formed in multiple layers, with the multiple layers being combined to form a layer package. Each layer can be punched, for example. A compound can be made by means of punch-stacking. As an alternative or in addition, the package layers of an optionally lower static part can be clamped or held together 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, correspondingly preferably not having any projections or bends or the like formed out of the resulting plane of extension transversely to the direction of thickness.

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

Compared to the above-described (maximum) thickness of the static part, the static part can have zones of lesser thickness, for example in the area of depressions starting from a side or broad 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 extension of the static part. In relation to the installation state, 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 already before the installation of the roller shutter box in a corresponding building opening, to the roller shutter box, specifically and preferably a roller shutter box bottom. 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 the context of this application and / or a separate fastening strap. It is preferred that said static part of the same thickness also has this same thickness (maximum) in the area of the form-fit section, but the functional part as a separate part can be thicker and can also include the static part in this area. In particular, it is preferred that the essential force absorption with regard to transverse to a longitudinal extension The forces acting on the roller shutter box are practically only effected by the aforementioned 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 also by cutting it out of a thicker sheet metal, for example by laser cutting.

The features of the above-described independent claims are important both individually and in any combination with one another, further features of an independent claim can be combined with the features of a further independent claim or with features of several independent claims, and also with only individual features of one or more of the further independent claims.

Thus, in one possible embodiment, the proposed 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 both in the horizontal and in the vertical leg for arrangement in a roller shutter box, with one of in any case at a given installation location of the roller shutter box The opening of the mounting part given above, through which the form-fit section can get into the form-fit receptacle, is narrowed in a depth direction of the roller shutter box in such a way that a release of the static part in the displacement position from the form-fit connection is prevented in the event of a load in the depth direction of the roller shutter box.

Further features of the invention are below, also in the description of the figures, often in their preferred assignment to the subject matter of claim 1 and / or the further independent claim (s) or explained to features of further claims. However, they can also be assigned to only individual features of claim 1 and / or the further independent claim (s) or the respective further claim or in each case be independent of importance.

In further detail, it is particularly preferred in terms of the method that the roller shutter box is displaced into a displacement position in a longitudinal or transverse direction of the mounting part after it has been placed on the mounting part. This makes it possible in a simple manner to provide different configurations in the mounting part with regard to interaction with the static part, wherein a configuration given in the displacement position, which then corresponds to the installation position, can be designed to release the static part from the positive connection to prevent a load in a depth direction of the roller shutter box. In an alternative embodiment, the configuration that creates the hindrance in the displacement position can also be part of the roller shutter box or the static part. With the sliding displacement, the configuration can be brought into a position that brings about the desired hindrance.

The form-fit connection is preferably provided as an underhand grip between a free end of the static part and the holding part.

The fixing of the underhand grip is furthermore preferably achieved - optionally in the above-mentioned displacement position - by a blocking part attached to the holding part, alternatively to the static part. The blocking part serves in particular to narrow the free space of the opening for the static part or for the form-fit section of the static part, which is in positive engagement with the mounting part, in the load direction to be observed, i.e. in the transverse direction of the roller shutter box.

The displacement of the static part from the locked position, i.e. corresponds to the insertion position, in the direction of said shifting position can take place in the longitudinal direction of the roller shutter box and / or the mounting part. In particular, the mounting part can provide a rail-like guidance of the static part and, via this, 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 mounting part, in which position the static part is prevented from shifting transversely to the direction of displacement by appropriate measures on the mounting 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 shifted transversely to the longitudinal extension of the holder part for moving it from the latched position into the sliding position, with a blocking part to be rearranged in the sliding direction in the course of or at the end of this sliding shift into an underhand position in order to prevent the static part from shifting back in the load direction to be observed, removing the underhand grip.

Thus, the narrowing of the opening can also be achieved by a blocking part which is to be arranged separately or is connected to the static part. This blocking part can be provided before and / or in the course of taking the latched position of the static part in a standby position, for example on the static part, from which standby position in the latched position of the static part the blocking part can be brought into the blocking position reaching the narrowing of the opening.

Thus, according to a possible embodiment, the blocking part can be attached to the static part in a vertically displaceable manner. From a standby position, in the engaged position of the static part, the blocking part can thus be lowered vertically, for example, to narrow the opening in the holding part.

The shifting of the blocking part from the standby position to the blocking position can be carried out manually with emphasis on the will. The blocking part can also be displaceable into a blocking position by virtue of its weight. According to a further possible embodiment, the blocking part can be spring-biased into the blocking position, for which purpose 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 by the weight alone, the blocking part is suitable for automatically lowering into the blocking position in the manner of a fall when the static part has reached the latched position.

To cancel the blocking position, for example to dismantle the static part with the roller shutter box attached, in such a configuration the blocking part must be lifted manually against the force of the spring.

As described above, the blocking part can be inserted as a separate position in the holding part, causing a narrowing of the opening, and fastened there, for example by means of a screw connection. Such a positioning of a blocking part in the mounting part can for example take place on site, immediately before the roller shutter box is mounted on the frame part.

In a further embodiment, the blocking part can also be an integral part of the mounting part as a whole. Thus, according to a possible embodiment, the opening can be designed according to the required constriction, with a built-in recess being formed on the mounting part on the side of the (constricted) opening - viewed in the longitudinal extension 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 extension of the mounting part in a form-fitting position.

With regard to the opening width viewed transversely to the longitudinal extent, the holding part can initially in principle completely 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 extension of the mounting part at least to such an extent that the static part can be inserted from the top vertically and, as a result of sliding displacement across the longitudinal extension of the mounting part, can be brought into the latching position, after which it can be a sliding displacement in the longitudinal direction of the holder part can be carried out into the blocking position.

Several such installation recesses can be provided on the mounting part, for example two, three or more such installation recesses distributed uniformly 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 one possible embodiment, the installation recess can be made by correspondingly cutting free an area of an otherwise in Be made with a narrowed opening continuous mounting part profile. In such a free-cutting area, the opening has only one opening edge, the opening edge of the mounting 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 fastening means that extends in the direction of the horizontal leg in the installed state. 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, the fastening formation can also be provided with a stop which limits a sliding displacement of the static part transversely to the longitudinal extension of the roller shutter box. The stop position can, as further preferred, be the position in which an optionally present blocking part can be displaced into a blocking position by weight, possibly spring-preloaded.

In this installed state (latched state), the installation 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 was previously, as is preferred in terms of the method, already at the Assembly was connected to the roller shutter box). In a preferred embodiment, this fastening means penetrates the fastening formation in the area of a penetration opening and engages in a roller shutter box section, in particular a section of the roller shutter box bottom part.

In addition, a latching projection can be formed at a distance from the fastening formation in the direction of the horizontal leg, for latching the static part on the roller shutter box. According to one possible embodiment, the latching projection can point in the same direction, starting from the horizontal leg, as the previously described fastening formation, and so on in the usual downward orientation of the static part.

The latching projection and the fastening formation can furthermore be formed 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 latching projection and the fastening formation, with a section of the latching projection also engaging under a mating section of the roller shutter box or the base part in such a way that a latching arrangement prevents a relative displacement of the static part with respect to the Counter-latching area having roller shutter box part is prevented vertically upwards.

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

The connecting legs, which are of different lengths, make it possible to achieve favorable assembly and disassembly, in particular of the lower static part in the roller shutter box. 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 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, the lower static part can be shifted relative to the upper static part, whereby a shorter connecting leg of the lower static part can be passed 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, viewed in the horizontal direction, without overlapping one another.

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

Description of the embodiments

Shown and described is a schematically and partially illustrated roller shutter box with reference to Figure 1 in the illustrated embodiment, a top part 2, a front wall 3, a bottom part 4, a bottom inspection part 5 and a rear wall 6.

In the roller shutter box 1, which is assembled from the parts mentioned in the 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, predominantly only a lower part of one in the figures the exemplary embodiments preferably two-part static part is shown. The static part 7 can furthermore have an upper part which can extend as far as the ceiling part 2 or, as is preferred in the context of the present application, beyond the ceiling part 2, penetrating an elongated hole in the ceiling part 2. Such an upper part is at least partially available 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 with the bottom part 4, the static part 7 is already prior to the in Figure 1 connected installation position shown, in the embodiment by fixing screws 8, 9, which, in the case of a static part 7 designed as a bent sheet metal part, for example, pass through a fastening leg 17 which is for example essentially parallel to the base part 4.

The static part 7 extends through a recess 10, which is also preferably embodied in the base part 4, and protrudes with a form-fitting section 11, here embodied as a tongue-like engagement projection, compare in particular Figure 3 , through the bottom part 4 through. The form-fit section 11 (engagement projection) can in particular be configured as one in the exemplary embodiment in the horizontal direction (based on an installation position, as shown, for example, in FIG Figure 4 is shown) angled plug-in nose be formed. In the assembled state of the roller shutter box, this form-fit section 11 can grip behind to an engagement recess 12 of the bracket part 13 fastened to the frame part 13, which is formed in a bracket section 19 of the bracket part 13, compare in particular Figure 2 , serve. The engagement recess 12 is also referred to above and below as a form-fit receptacle.

This rear grip is - also - prevents the roller shutter box from being lifted out vertically upwards together with the connected static part. A significant stress on such a roller shutter box 1 in the installed state, compare in particular Figure 3 , but is in a depth direction T, whereby this can of course also be given 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 referred to above and below as the insertion position, snap-connected to the mounting part 13 and then moved to a second position, a displacement position S2, which is also referred to as the installation position above and below (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 extension of the mounting 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, if applicable, the static part 7 alone has already been pushed forward, but could still be brought back into a position in the depth direction T by sliding it back it can be removed vertically upwards.

The prepared roller shutter box 1, i.e. That is to say, the roller shutter box 1 connected to the static part 7 is preferably set so that the area of the static part 7 having the form-fitting section 11 is lowered essentially from the top vertically through the opening 15 that is widened transversely to the longitudinal extension of the mounting part 13, after which the form-fitting engagement of the form-fit section 11 into the engagement recess 12 of the mounting part 13 of the roller shutter box 1 together with the static part 7 (or with the several static parts 7) transversely to the longitudinal extension of the mounting part 13 (essentially in the direction of the outside of the building).

In this vertical setting, the procedure can in particular be such that the form-fit section already has an alignment that is also given in the installation position, here as the displacement position S2.

From the inserted position S1, the inserted position, takes place accordingly below in the Figures 1 to 6 and 7 to 9 Shown embodiments subsequently a sliding displacement in the direction of arrow a into the displacement position S2, in which displacement position S2 the width b of the opening 15 viewed transversely to the longitudinal extension of the holding part 13 is reduced in such a way that at the rear of the region of the static part 7 having the form-fit section 11, a support is achieved which prevents the static part 7 from being displaced backwards while the form-fit connection between the form-fit section 11 and the engagement recess 12 is canceled.

In the in the Figures 1 to 6 The first embodiment shown is in the shift position S2 of the roller shutter box 1, which can also correspond to the installation and use position, such as in particular from Figure 2 can be seen, a blocking part 14 inserted into the holding part 13. It can be screwed to the mounting 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 mounting part 13 in the displacement position S2 compared to the width in the latching position S1 (cf. Figures 5 and 6 ) is narrowed in such a way that the static part 7 located in the form-fit connection with the mounting part 13 cannot move out of the form-fit in the depth direction. As described, a vertical blockage is preferably given in any case by the interaction of the engagement projection and engagement recess 12.

In the event that expansion of the static part 7 becomes necessary, for example when a roller shutter box shaft is to be expanded with a roller shutter box armor, the static part 7 can be detached from the roller shutter box 1, in this case by loosening a screw connection with the bottom part 4, and then within the holder part 13 can be shifted from the shifting position S2 into the latching position S1 in accordance with the shifting of the roller shutter box as a whole carried out during installation, but now only with reference to the static part 7, as indicated by the recess 10 provided for this in the bottom part (see Figure 4 ). The recess 10 is viewed in the longitudinal extension of the mounting part 13 on the displacement path from a Locking position S1 in the shifting 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 swiveled out and removed in the usual way without the need to move the entire roller shutter box 1 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. For further details of the mounting part 13 and its connection to the frame part 16 can also refer to the EP 2636839 A2 and the EP 1710388 B1 to get expelled. The explanations in these publications with regard to a possible configuration of the mounting part 13, also referred to there as an adapter strip, are hereby fully incorporated into the disclosure of the present application, also for the purpose of including the features of these older applications in the claims of the present application. The same applies to the German patent application 10 2018 106 423 referenced.

According to the method now described here, the procedure for installing a roller shutter box 1 can be as follows.

The roller shutter box 1 is initially assembled in the workshop, usually outside of a building in which it is ultimately to be installed, with regard to some or all of the parts which are related 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 so that it can be handled uniformly for installation with the roller shutter box 1.

Further in the explanations according to Figures 1 to 6 and 7 to 9 stipulated 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 shift position S2. In view of this, according to the Figures 1 to 6 The illustrated first embodiment, the holder part 13 is provided with the blocking part 14 at the point or locations concerned. For this purpose, the blocking part 14 is preferably screwed to the mounting 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 also be attached to the mounting part 13 only after such a connection between the mounting part 13 and 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 mounting part 13 is initially and essentially designed in such a way that, with respect to the opening 15, there is basically a constriction according to the above-described exemplary embodiment in the area of the arranged blocking part 14.

Viewed in the longitudinal extension of the mounting part 13, an installation recess 20 is formed laterally, preferably on both sides, of a section of the mounting part 13 forming the blocking part 14 on the mounting part 13. In the area of these installation recesses 20, the widened width of the opening 15 that enables the vertical insertion of the area of the static part 7 that has the form-fitting section 11 is shown as shown in FIG 8 given. In this case, the installation recess 20 can be formed by cutting out a partial block section from the mounting part 13. The opening 15, which is otherwise and in any case formed with two opening edges in the installation position, can, as shown, be formed in the area of the installation recess 20 with only one opening edge.

In this embodiment, too, the prepared roller shutter box 1 with the static part 7 is initially placed in the area of the installation recess 20. After taking the form-fit position between the form-fit section 11 and the engagement recess 12 of the mounting part 13, a sliding displacement of the roller shutter box 1 takes place 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 mounting part 13, in this embodiment the displacement position S2 of the static part 7 can be taken essentially freely between two installation recesses 20 following one another in the longitudinal direction of the mounting part 13.

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

Furthermore, the roller shutter box 1 prepared as described can be placed in an inclined raised position on the mounting part 13 and shifted slightly forwards, that is to say towards the outside of the house, and then lowered. This also results in the engagement of the form-fit section 11 of the static part 7 in the corresponding area of the holding part 13 and the latching of corresponding parts of a bottom part 4 of the roller shutter box 1 with the holding part 13.

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

With regard to a given in the displacement position S2, or the installation position, hindrance of the static part 7 from a substantial movement transversely to a longitudinal extension of the mounting part, be it through the blocking part or a mere narrowing of the opening, the above and below also mentioned hindrance position 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. Insofar as the static part 7 is designed in two parts, the connection to the lower part, which is already connected to the roller shutter box 1 in the described manner, can also initially be made. The upper part can also be connected to the lower part when it is inserted.

The fact that preferably an upper and a lower part, which are for example screw-connected to one another, are provided with regard to the static part 7, this lower part can be removed if the static part 7 is to be removed, whereby an expansion of the lower part is usually sufficient release from the upper part and remove in the manner described by lateral displacement counter to the sliding direction a from the displacement position S2 and thus also remove from the blocking part 14, so that it is moved to an area in which it can then be easily lifted upwards by angling and removed from the roller shutter box 1. The position of the static part 7 reached in this way relative to the holding part 13 can be the latched position S1 described. A sufficient working opening is then provided, 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, if necessary.

The Figures 10 to 15 show a further embodiment in which the blocking part 14 is attached to the static part 7 so as to be vertically displaceable. 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 it can be displaced in the vertical direction relative to the static part 7 in the usual installation situation of the static part 7 or the roller shutter box 1.

The blocking part 14 can, as is also preferred, be arranged on a leg 21, which is essentially horizontally aligned in the installation situation, essentially rearward of the form-fit section 11, the horizontal leg 21 providing a vertical guide to the blocking part 14 comprising this horizontal leg 21 in the form of a fork in the exemplary embodiment.

The blocking part 14 can be spring-preloaded in the direction of 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 loads the blocking part 14 acts (see also the sectional views in Figures 11 and 14th ).

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

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

By subsequently sliding the static part 7 in the direction of arrow c (see Figure 13 ), as is customary in the above-described exemplary embodiments for bringing about the form-locking engagement, the form-locking section 11 is shifted into the engagement recess 12. The at the same time dragged along in the direction of arrow c blocking part 14 loses in the course of this sliding displacement, the support on the leg 23, as a result of loading via the compression spring 22 and / or the weight of the blocking part 14 according to the illustrations in Figures 13 to 15 falls into the blocking position in which the blocking part 14, seated on the displacement recess 18, narrows the width b of the opening 15 in such a way that a backward displacement of the static part 7 against the direction of arrow c can be prevented.

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 8, 9, which penetrate the horizontal leg 21 in the vertical direction. Alternatively, a clamp or the like spanning the horizontal limb 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 bottom part 4, the blocking part 14 is manually shifted against the force of the compression spring 22 vertically upwards into a position releasing the entire width b of the opening 15, after which the Static part 7 can be removed in the usual way.

The analysis part used in this embodiment may be a analysis part according to that shown in FIGS Figures 16 to 19 be illustrated embodiment. Such a static part 7 can also be used in the further embodiments according to FIGS Figures 1 to 9 Find use.

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

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

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 limb 21 and the vertical limb 25 and, moreover, the form-fit section 11 with the bridging section 26 are preferably designed in one piece and of the same material. For example, the static part 7 is produced according to laser cutting.

The static part 7, as shown, can be produced in one layer. Furthermore, the static part 7 is undeformed, and accordingly does not have any bends or projections that protrude or repel outwardly from the set 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 as a result of free cutting. An upper static part 29 can be attached via this, via which upper static part 29 a connection with 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 is also a uniform static part is manageable by itself.

As in connection with the embodiment of 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, for example in the form of bores, which are oriented perpendicular to its longitudinal extension.

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

Figure 21 FIG. 11 shows a further embodiment of a lower static part 30 which is formed in one piece with the same thickness and has a blocking part 14, preferably resiliently supported on the horizontal leg 21, according to the one shown in FIG Figures 10 to 15 illustrated embodiment.

The fastening of the lower static part 30 to the roller shutter box 1, in particular to its bottom part 4, is also achieved here as a result of a screw connection. For this purpose, the horizontal limb 21 has a fastening formation 34 which projects downwards in the installed state. This projection-like fastening formation 34 is preferably formed in one piece and made of the same material with the horizontal leg 21, further in particular with the entire lower static part 30, in this case further preferably having the same thickness d as the remaining lower static part 30.

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

After the screw connection, the floor revision part 5 can be attached or latched.

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

The above-described arrangement and configuration of the latching projection 37 and the fastening formation 34 enable the lower static part 30 to be held in a form-fitting manner on the roller shutter box 1. This form-fit position can be secured via the fastening means 36.

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

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

The connection limbs 32 can be connected to one another via a fastening limb 17 extending between them on the foot side and essentially forming the horizontal limb 21, which fastening limb 17 can form the form-fit section 11 in the region of its free end.

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

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

The lengths l, l 'and m, m' are selected 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 shifting position S2 in the direction of the latching position S1 of the connecting legs 32 of shorter length m ' in the course of the displacement under the connecting leg 33 of shorter length l 'of the upper static part 29 can be passed.

The added total length of the attachment 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 provided on the connecting legs 33 (fastening screws 28 and / or recesses 27) for connecting the upper static part 29 to the lower static part 30 are provided in the installed state, viewed in the horizontal direction, without overlapping one another, are accordingly projected in a common vertical plane, preferably in the vertical direction Side by side spaced apart.
