STATIC PART FOR A ROLLER SHUTTER BOX

Description

field of technology

[0001] The invention relates to a static part for a roller shutter box, for stiffening the roller shutter box against loads, such as wind loads, wherein the roller shutter box can be placed on a frame part, such as a window frame or door frame, with a connecting part for fastening the static part to a building part, such as a window lintel, and a connecting part for connecting the static part to the frame part, optionally by means of a stiffening part arranged between the static part and the frame part, such as an adapter strip. State of the art

[0002] Structural components of the type in question are known, for example, from DE 10 2012 101 895 A1 and DE 10 2014 111 792 A1. In particular, to stabilize a roller shutter box mounted on a frame part, such as a window or door frame, it is known to provide this with a structural component. This structural component passes through the roller shutter box with a roller shutter box part and is preferably connected to the frame part at the base. A connecting component of the structural component can further be used to fix the structural component to a building part, for example a building ceiling part or, for example, a window or door lintel. In this way, in particular in the case of wind loads pressing on the window or door, the corresponding loads, which could otherwise lead to undesirable movement of the window or door and / or the attached roller shutter box, can be absorbed.

[0003] For the initial alignment and fixing of the roller shutter box, preferably together with the window or door frame, in the building opening, it is known to fix the alignment, in particular between the roller shutter box and the building part, by means of wedges or blocks inserted into the gap resulting between the roller shutter box and the building part. This provides an initial (temporary) fixation, which is intended in particular to prevent slipping or tipping of the roller shutter box, optionally, as is also preferred, together with the frame part, during the final fixing, for example by screwing. The wedges and blocks are preferably provided as loose parts. The final fixing, due to a preferred screwing, is more preferably carried out using the connecting part of the structural part.

[0004] WO 2018 / 076111 A1 discloses a clamping element, particularly for the purpose of initially securing, for example, a frame part in a building opening. This clamping element is inserted into the joint between the frame part and the building part. By rotating a screw provided in the clamping element, the clamping areas are moved into an exposed position, in which exposed position, a claw engagement with the facing surface of the building part and / or the frame part can be achieved. These clamping elements are also available as loose parts.

[0005] DE 20 2014 101 111 U1 discloses a structural component for a roller shutter box in which the connecting part is connected to a window reveal by means of a screw / dowel connection. Wedge elements are arranged between the connecting parts of the window reveal. DE 20 2015 102 719 U1 discloses a structural component for a roller shutter box that can also be connected to a reveal, such as a window reveal, by means of a screw connection. The connection can only be established if the screw connection is also present.

[0006] From EP 047 563 A1 a spreading part is known with which a window or door frame can be suitably pre-positioned in a corresponding receptacle. Summary of the invention

[0007] Based on a prior art such as that known from DE 20 2015 102 719 U1, the invention is concerned with the task of improving a static part of the type in question, in particular with regard to handling during installation of the roller shutter box on the building part.

[0008] This object is achieved in the subject matter of claim 1, wherein the activation part is designed with a screw drive and the activation part is supported on the static part via the screw drive, wherein a spring drive is designed as an alternative or in combination with the screw drive.

[0009] The static part is designed with the activation part for at least only the external friction and / or form-fitting connection of the frame part to a building part, such as a window lintel.

[0010] The activation part can be activated by a separate action. For example, a part, such as a clamp, can be severable, thus releasing a spring preload that places the activation part in the desired position to provide the support between the frame part and the building. However, the activation part can also be activated immediately, without requiring any separate action, so that it automatically provides the support when the frame part is inserted, preferably together with the roller shutter box, into the building opening.

[0011] A possibly provisional fixing of the frame part, further possibly together with the roller shutter box, preferably via the static part, but also possibly directly via the roller shutter box, is carried out according to the invention in one embodiment via a part of the static part that is specifically activated by the user. Accordingly, this is preferably not a loose part, but rather a component of the frame part or of the static part installed on or in the roller shutter box. The activation part is therefore already present for activation immediately upon insertion of the roller shutter box, preferably together with the frame part, into the building opening and subsequent alignment.The activation of the activation part is preferably carried out by a deliberate triggering by the user, for example as a result of a direct influence on the orientation of the activation part, further for example as a result of moving the activation part from a basic position into a fixed position.

[0012] In such an activated fixing position, a compressive bracing can be achieved between the building part and the frame part, more particularly a clamping fixation, which allows at least a temporary fixation of the frame part and the roller shutter box arranged thereon. Such a compressive bracing or clamping fixation can be maintained after a final fixation of the frame part to the building part, for example, as a result of a final screwing of the structural part to the building part.

[0013] In particular, the surface of the activation part facing the surface of the building part that interacts with the activation part can, as is also preferred, be designed for frictional and / or positive connection with the building part. Accordingly, a profiling of the relevant surface of the activation part can be provided.

[0014] This screw drive can be operated by the user, as is preferred, using a standard tool to activate the activation part. The screw drive can be used to move the activation part from a deactivated home position to an activated position for compressive bracing between the building part and the frame part. Furthermore, the screw drive can also be used to return the activation part to the deactivated home position.

[0015] For this purpose, the screw drive can, for example, have a spindle that interacts with a spindle mount of the activation part to move the activation part. Part of the activation part can be an extension part, which, when activated, can be moved into an exposed position relative to the roller shutter box, more preferably relative to the static part, in particular to its connecting part.

[0016] To secure the assumed compression-tension position, especially until the frame part or the static part is finally secured after final screwing, a measure can be taken to prevent the activation part from shifting backwards in the compression-tension position. This can be achieved, for example, by securing the spindle and / or the activation part or extension part. The thread of the screw drive can also be designed to be self-locking by selecting the appropriate thread pitch.

[0017] Alternatively, or in combination with the screw drive described above, the activation part can also be designed with a spring drive. This spring drive can, if necessary, support the screw drive, particularly with regard to the pressure tension to be built up between the building part and the activation part, and thus between the building part and the roller shutter box. The spring drive can also, if necessary, serve solely to move the activation part from the deactivated basic position into the active pressure-tension position, for example, to automatically move the activation part after the targeted release of a detent securing the deactivated basic position or the like.

[0018] Such a spring drive, for example in the form of a compression spring, can also generally hold the activation part in the activated position. In this case, the activation part is activated, as explained above, without any separate intervention being required. When the frame part is inserted, for example, pivoted in, together with the roller shutter box into the building opening, the activation part is automatically aligned to the compression-tension position against the restoring force of the spring, depending on the gap height between the roller shutter box and the building part.

[0019] In a further embodiment, the activation part facing the building part can have a structure for interlocking with the building part. For example, a plurality of wedge- or claw-shaped projections or elevations can be formed on the surface of the activation part facing the building part.

[0020] In addition, a surface of the activation part facing the building part, more preferably a gripping surface of the activation part, can be displaced approximately parallel to the plane of a roller shutter box ceiling for activation. The activation part can be displaced according to a sliding wedge. This can preferably result in a parallel alignment of the above-described surface to the plane defined by the roller shutter box ceiling in every displacement position of the activation part between the deactivated basic position and the active pressure-tensioning position. The roller shutter box ceiling extends essentially in a horizontal plane in the installed and used position of the roller shutter box.Accordingly, the activation part with its preferably provided gripping surface is brought to the facing surface of the building part while maintaining a substantially horizontal alignment, with which facing surface of the building part a gripping is to be brought about in particular.

[0021] According to the invention, the activation part is supported on the structural part via the screw drive. In this regard, support on the connecting part of the structural part is also preferred. This allows corresponding compressive bracing to occur directly in the area that is also used for the final fixation of the frame part and the roller shutter box attached to it, namely in the area of ​​the section of the structural part that extends beyond the roller shutter box toward the building part. In this preferred embodiment, the roller shutter box itself is free of compressive bracing.

[0022] The activation part or the screw drive preferably provided for moving the activation part can thus be accessible according to the connection part of the static part after alignment of the roller shutter box together with the frame part essentially in the connection area between the roller shutter box and the building part.

[0023] The connecting part can also have one or more openings for an anchoring screw. For example, two such openings can be provided, which can be located on either side of the support of the activation part on the connecting part. The anchoring screws provide a final and permanent attachment of the frame part, and through this, the roller shutter box, to the building part.

[0024] A possible embodiment in which the activation part is accessible for activation from the rear of the roller shutter box has proven particularly advantageous. Activation can therefore take place from an easily accessible position. If necessary, the roller shutter box can have an opening or recess in the roller shutter box housing for accessing the screw drive of the activation part using a conventional tool, which opening or recess is preferably closed after anchoring is complete. To activate the activation part and / or to secure the anchoring screws, a rear wall of the roller shutter box housing can also be removed or relocated, for example pivoted, into a position accessible to the screw drive of the activation part and the anchoring screws.

Description of the embodiments

[0026] Shown and described is, firstly, with reference to Figure 1 , a roller shutter box 1, preferably in the form of a top-mounted roller shutter box, which is mounted on a frame part 2, which can be, for example, an upper window frame or door frame. The roller shutter box 1 is further preferably provided with a static part 3 and with an activation part 26 that enables a first fixation.

[0027] The roller shutter box 1 further comprises a rear side 4 facing a room and an outer side 5. Above the roller shutter box 1, a building part 6, for example in the form of a building ceiling, further, for example, in the form of a window or door lintel, can be provided. This building part 6 preferably serves to anchor the roller shutter box 1 together with the frame part 2, wherein in the aligned installed state of the roller shutter box 1 and the frame part 2, as this installed state is shown, for example, in the Figures 1 and 2 and 12, the surface 7 of the building part 6 facing the roller shutter box 1 is spaced from the facing surface 8 of the roller shutter box 1 in the region of a roller shutter box ceiling 9. In this regard, a mounting gap 10 with an exemplary gap height a of approximately 30 to 80 mm, further, for example, approximately 40 to 60 mm, is preferably created.

[0028] In the anchored state, in which the installation situation is fixed for normal use, the frame part 2 can be connected together with the roller shutter box 1 to the building part 6 by the structural part 3 penetrating the roller shutter box 1. This structural part 3 serves in particular to absorb possible movements of the frame part 2 toward the rear side 4 and / or the outer side 5, furthermore in particular in the case of wind forces acting on the window or door.

[0029] For this purpose, the static part 3 can, as also shown, be essentially formed in two parts, comprising a static lower part 11 and a static upper part 12. The static lower part 11, viewed in an extension transverse to a longitudinal extension L of the roller shutter box 1, can be L-shaped, with a connecting leg 13 extending vertically in the installed state and a base leg 14 extending essentially horizontally.

[0030] The base leg 13 can be aligned substantially parallel to a roller shutter box base 15 and, at the end facing away from the connecting leg 13, can carry a downwardly stepped connecting part 16. This connecting part 16 is formed on the front side of the base leg 14, facing the outer side 5 of the roller shutter box 1. With this connecting part 16, the static lower part 11 engages in a correspondingly formed rear grip of a preferably provided stiffening part 17 in the manner of an adapter strip, which is screwed to the top of the frame part 2. A window-like opening can be formed in the roller shutter box base 15 for this engagement.

[0031] According to a preferred embodiment, the static upper part 12 can also be formed substantially L-shaped in an extension transverse to the longitudinal direction L of the roller shutter box 1. A connecting leg 18 extending substantially vertically in the installed state can be provided, which preferably merges in one piece and of the same material into a connecting part 19 extending substantially horizontally in the installed state. According to the illustrated embodiment, the connecting part 19 and the connecting part 16 can be arranged oriented away from one another, viewed in the longitudinal direction L.

[0032] The vertically extending connecting legs 18 and connecting legs 13 of the static lower part 11 and the static upper part 12 are rigidly connected to each other in the installed position. For this purpose, as for example in Figures 5 and 6As shown, a screw connection 20 may be provided. The connecting leg 18, together with the connecting leg 13, forms a vertical leg 21. This extends, starting from the base leg 14, penetrating the interior of the roller shutter box 1, beyond the roller shutter box ceiling 9, preferably passing through an opening 22 provided in the roller shutter box ceiling 9.

[0033] The structural part 3, as well as preferably the stiffening part 17, is made of a metal material. These can be bent sheet metal parts.

[0034] As can be seen particularly from the illustrations in the Figures 1 and 3As can be seen, in addition to the roller shutter box ceiling 9 and the roller shutter box base 15, a roller shutter box outer wall 23 and a roller shutter box rear wall 24 can also consist of plate-shaped, preferably extruded hollow-chamber plastic parts, which can be plug-connected to one another, particularly in the corner areas. As further described in particular in Figure 3 As shown schematically, the box interior can be lined with an insulating body 25, leaving a cavity to accommodate the roller shutter (not shown) and its roller which can rotate about a roller shutter axis x.

[0035] To insert and install frame part 2 and roller shutter box 1 in a building opening, the roller shutter box 1 provided with the static part 3 can first be plug-connected to the frame part 2, in particular due to a plug-in connection between the connecting part 16 of the static part 3 and the frame-side stiffening part 17. After this, frame part 2 and roller shutter box 1 can be pivoted together into the building opening in preparation for anchoring.

[0036] As a preparatory measure for the final anchoring, the arrangement of roller shutter box 1 and frame part 2 must first be (temporarily) fixed in the desired orientation. The activation part 26 of the roller shutter box 1 or the static part 3 serves this purpose. In accordance with the preferred multiple arrangement of static parts 3 over the length of the roller shutter box 1, viewed in longitudinal extension L, a plurality of activation parts 26 are preferably also available for fixing.

[0037] The activation part 26 can be designed like a sliding wedge for sliding displacement along an imaginary line z, which in a cross section through the roller shutter box 1, in which cross section the roller shutter axis x of the roller shutter (not shown) is represented as a point, in the installed state of the frame part 2 to be fixed together with the roller shutter box 1 according to Figure 1an acute angle α to a horizontal plane E, preferably also defined by the surface 7 of the building part 6, of approximately 30 to 60 degrees, further approximately 45 degrees.

[0038] In the installation situation, the plate-shaped connecting part 19 of the static part 3 preferably extends above the roller shutter box ceiling 9, occupying a small distance of a few millimeters, for example of 3 to 10 mm, from the surface 8 of the roller shutter box ceiling 9.

[0039] According to the Figures 1 to 11In the illustrated embodiments, for example, due to the free cut and bending, a guide section 27 can be formed which is formed integrally with the connecting part 19 and of the same material, which guide section is oriented, including the above-described angle, in the direction of the box interior and in the direction of the roller shutter box rear wall 24. Along its surface facing an extension part 44 of the activation part 26, the extension part 44 can be guided and displaced, wherein a window-like opening 28 allowing the throughput of the extension part 44 is further provided in the connecting part 19.

[0040] A further angled leg 29 of the connecting part 19 can form a support base 30. On this, the extension part 44 of the activation part 26 of the first embodiment sits in the deactivated position according to the Figures 1 to 3preferably such that the activation part 26 does not protrude beyond the surface 31 of the connecting part 19 opposite the surface 7 of the building part 6.

[0041] Facing the surface 7 of the building part 6, the activation part 26 or the extension part 44 has a structuring 32. This can be provided by the arrangement of a plurality of isolated tips with a circular or square base (see in particular Figure 4 ). In particular, the tips of this structuring 32 span a claw surface F which, upon displacement of the activation part 26 along the line z, can be displaced preferably parallel to the roller shutter box ceiling 9, more preferably parallel to the horizontal plane E.

[0042] The extension part 44 of the activation part 26 of the Figures 1 to 9The first embodiment shown is displaceable via a screw drive 33. For this purpose, as initially provided, a screw 36 can be provided with its shaft 34 seated in a threaded bore 35 of the support base 30. The screw head 37 points in the direction of the roller shutter box rear wall 24, while the free end of the screw 36 facing away from the screw head 37, passing through the threaded bore 35, serves to act on the extension part 44.

[0043] To activate the activation part 26, the roller shutter box rear wall 24, as shown in Figure 2 shown schematically in dash-dotted representation, can be swung into an open position or alternatively completely removed in order to then be used in the Figures 1 to 9 shown first embodiment to be able to act on the screw head 37 of the screw drive 33.

[0044] For this purpose, the insulating body 25 can further comprise a wedge-shaped cutout 38 (see Figure 3 ).

[0045] Preferably using a conventional tool, a spindle-like sliding displacement of the activation part 26 or the extension part 44 along the guide section 27 can be achieved via the screw head 37, until it reaches a position as shown in the illustrations in the Figures 8 and 9 , in which the structuring 32 of the activation part 26 engages frictionally and / or positively with the facing surface 7 of the building part 6. In this position, a compressive bracing between the frame part 2 and the building part 6 can be achieved via the static part 3. The roller shutter box 1 and, with it, the frame part 2 are then fixed for the final anchoring to be carried out.

[0046] This anchoring is also preferably carried out from the rear of the roller shutter box 1, more preferably with the roller shutter box rear wall 24 open. For this purpose, the static part 3, in particular the connecting part 19, has several, in the illustrated embodiment two, through openings 39 for anchoring screws 40. These through openings 39 can, as also preferred and for example from Figure 5 As can be seen, viewed in the longitudinal extension L of the roller shutter box 1, the opening 28 for the activation part 26 is provided in the connecting part 19 on both sides.

[0047] The anchoring screws 40 to be inserted from the rear of the roller shutter box 1 are driven, preferably on both sides of the angled leg 29 of the connecting part 19, through the passage openings 39 into the building part 6 to anchor the static part 3 and, via this, the roller shutter box 1 to the frame part 2 (see Figures 8 and 9 ).

[0048] How to continue in the Figures 10 and 11 As shown schematically, a spring drive 41 can also be provided as an alternative to a screw drive 33. For this purpose, the activation part 26 can also be guided in the form of an extension part 44 along the line z, wherein the activation part 26 is loaded in the direction of the activation position by a compression spring 42 supported on the support base 30.

[0049] The activation part 26 can be in the spring-loaded basic position according to Figure 10and be secured accordingly in this deactivated basic position, for example by a pin 43 passing through a partial area of ​​the activation part 26 and resting on a surface, for example the support base 30. This pin 43 is preferably accessible from the rear of the roller shutter box and can be removed to activate the activation part 26, after which, due to the then released force of the compression spring 42, the activation part 26 is pushed forward into the activated protruding position to achieve the friction and / or form-fitting connection with the building part 6 (cf. Figure 11 ).

[0050] Figure 12shows an embodiment in which the activation part 26 is arranged directly on the roller shutter box part 1. In the same configuration, although not shown, it can also be arranged on the static part. For example, this can be pivotably mounted on the surface 8 of the roller shutter box cover 9, with a geometric pivot axis that preferably runs in the longitudinal direction L of the roller shutter box 1.

[0051] In this embodiment, the activation part 26 is activated immediately, without any separate action being required.

[0052] A spring drive 41, for example in the form of a compression spring, which is supported at one end on the roller shutter box 1, for example on the roller shutter box ceiling 9, and at the other end acts against the activation part 26, loads the activation part 26 in the direction of a preferably stop-limited distance position from the surface 8 of the roller shutter box ceiling 9.

[0053] When the roller shutter box 1 is inserted, for example pivoted, into the building opening, the activation part 26 is automatically aligned depending on the gap height a in the mounting gap 10. The activation part 26 is aligned via the surface 7 of the building part 6 against the restoring force of the spring drive 41 into the activation position, in which engagement with the surface 7 is achieved.
