Description

According to the preamble of claim 1, the invention relates to a connection arrangement for connecting a winding shaft box of a building opening shading device, such as a roller shutter with a window or door frame, and a winding shaft box equipped with such a connection arrangement.

The German Utility Model DE 92 04 891 U1 remove an awning whose awning housing is fixed to a wall or ceiling. For this purpose, a console is provided, which is dowelled to the wall or ceiling and having angled lugs are hooked into the corresponding, oppositely directed hooks of the awning housing.

The European patent application EP 2 843 179 A1 discloses a roller shutter box which is attached to a wall via an adapter profile. The adapter profile has hook strips, in which the box is hooked with corresponding counter hooks on its rear side wall.

On top roller shutters the winding shaft or roller shutter box sits on top of the window or door frame. Usually, the roller shutter box is preassembled at lying window frame with the window frame to form a complete unit and then used as a unit in the designated building opening on the building.

Although this is the main fixation of the shutter box on Window frame often on metal bracket, which are attached to the front side panels of the shutter box on the one hand and the vertical struts of the window frame on the other hand, as for example from the German patent application DE 10 2005 055 384 A1 or the European patent specification EP 1 775 416 B1 evident. Nevertheless, while the winding shaft box is placed with its bottom on the upper horizontal strut in the installation position of the window frame, which thus carries the main load of the box.

Even in order to bridge gaps and manufacturing tolerances and to prevent it from passing between the upper horizontal strut of the window frame and the winding shaft box, but also to stabilize the attachment of the winding shaft box on the window frame, there are also known connection arrangements, the connection of the box bottom Make the upper horizontal bar of the window frame.

A generic connection arrangement with a floorboard profile of the winding shaft box and an attachable to the upper horizontal strut of the frame adapter profile is the European patent EP 1 710 388 B1 refer to.

Proceeding from this, the present invention seeks to provide a winding shaft box and a connection arrangement therefor, with which a simple assembly of the winding shaft box on the window or door frame is possible.

This object is achieved with regard to the connection arrangement with the features of claim 1, with regard to the winding shaft box having the features of claim 8.

According to the invention, the adapter profile of the connection arrangement has engagement projections designed as hook strips, which in the case of an adapter profile mounted on the horizontal strut, in the assembly position with upward directed Outside lying frame are open towards the top. The bottom board profile of the connection assembly according to the invention further comprises counter-engagement projections, which are engageable with the engagement projections of the adapter profile and this when attaching the winding shaft box with its bottom board profile from the top of the mounted on the horizontal frame adapter profile are open at the bottom and in the after Hang the hook strips of the adapter profile open at the top. In this case, according to the invention, at least one of the engagement projections of the adapter profile on a protruding locking projection, which is associated with a Gegenrastvorsprünge a Gegenrriffsvorsprünge the floorboard profile, which pushes when hanging in attack on the locking projection and then resiliently past it in the back handle. The latching projection stands on an outer side of the attack projection, which is turned down when lying in the mounting position frame and mounted thereon adapter profile. The winding shaft box according to the invention is equipped with a corresponding connection arrangement, wherein the floor board profile is connected to the winding shaft box.

By the present invention formed engagement projections on the adapter profile or these associated Gegeneingriffsvorsprünge the floor board profile, the installation of the winding shaft box on the window or door frame is greatly simplified. For the frame is usually placed with outwardly facing side on mounting brackets to mount the guide rails for the building opening shading device on the window frame. If the winding shaft box can then be hooked onto the adapter profile from above at the top of the window frame after mounting the adapter profile on the upper horizontal strut of the window frame, this is much easier than if it had to start from below, or the frame would have to turn over the hanging of the winding shaft box.

After assembling the winding shaft box to the frame is the thereby arising overall unit erected and used, for example, in the window opening on the building. By the latching projection on the adapter profile and the associated counter-latching projection on the floor board while a securing device is provided in an advantageous manner, which prevents slipping of the winding shaft box against the Einhängrichtung - ie towards the window outside. Characterized in that the locking projection protrudes on the outer side of the engagement projection of the locking projection and the counter-locking projection are designed so that the hanging is not hindered and the inside of the engagement projection as a flat surface and thus as an inclined plane can slide off the corresponding counter-engagement projection.

It is advantageous if the upwardly open as hook strips formed engagement projections of the adapter profile each have a plane, obliquely upwardly facing inside, which forms an inclined plane and designed as downwardly open Gegenhakenleisten formed Gegeneingriffsvorsprünge the floorboard profile also a plane, however have obliquely downwardly facing inside, which are slidably down when hanging the winding shaft box with its floor board profile on the frame mounted on the adapter profile or slide on the engagement projections of the adapter profile in the desired, suspended position gravity assisted. The assembly is further simplified.

It is particularly preferred if that engaging projection, which carries the locking projection projecting therefrom, is located above the lowermost engagement projection in the mounting position lying frame and mounted thereon adapter profile and provided for locking on the locking projection Gegenrastvorsprung not on the on the engagement projection with the locking projection is arranged to be engaged counter-engagement projection, but is located on the opposite the engagement projection with the locking projection next lower engagement projection to be suspended counter-engagement projection. Because of this, the latching projection and the counter-latching projection can be designed so that the Vorbeidrücken of the counter-latching projection on the Locking projection for locking the fuse against sliding down the winding shaft box disturbs the suspension movement when mounting the winding shaft box on the lying in the mounting position frame as little as possible.

In a further development of the locking projection is formed in the form of a relation to the counter-detent projection shorter, but wider locking lug and the counter-detent projection in the form of a relative to the locking projection longer, but thinner leaf spring. The leaf spring forming the counter-detent projection can advantageously be aligned and have such a length that it presses against the detent projection during the engagement of the reel shaft box with its spring leaf on the detent projection and relaxes in the detent projection behind the engaging rear handle after hanging the reel shaft box. This avoids, on the one hand, that the prestressing force becomes too great when the counter-detent projection is in engagement while being hooked in on the detent projection, and, on the other hand, that a residual prestressing force remains after the suspension, which leads to material fatigue and thus to permanent fracturing of the detent projection or counter-detent projection would lead, which would ultimately be associated with a failure of the safety device against sliding down the winding shaft box.

In order to wind-tight seal due to manufacturing tolerances possibly occurring gap between the adapter profile and the floorboard profile or between the floorboard profile and the window frame even in storm, the floorboard profile, the adapter profile or both may be provided with sealing lips. In this case, plastic profiles, as both the floorboard profile and the adapter profile are preferably formed, can be produced inexpensively with anextruded sealing lips made of rubber or silicone rubber or the like.

To attach the floorboard profile to the roller shutter box, the floorboard profile advantageously has a plurality of screw channels extending along the profile, on which it engages with the two box side parts of the frame Winding shaft box is screwed.

For mounting the adapter profile on the upper horizontal strut of the frame, however, Klipselemente may be provided which protrude from the base plate of the adapter profile to the horizontal strut and use corresponding window frames of most window manufacturers already provided Gegenklipselemente.

A greater compatibility of the winding shaft box according to the invention to different frames of different manufacturers can be achieved if the winding shaft box attaches different adapter profiles with different Klipselementen, if the connection arrangement thus comprises a plurality of different adapter profiles with different Klipselementen so that the connection arrangement compatible counter-clip elements of different frames is. Alternatively or additionally, clip elements for more than the counter-clip elements of a window manufacturer could also be provided on an adapter profile.

A further advantageous development of a winding shaft box according to the invention relates to a flag, which is attached to the floor board profile and presses in the installed state of the floor board profile in the winding shaft box on an example designed as Styrofoam or PU foam layer insulation layer, which is arranged on a revision flap, which a adjacent the building inside the floorboard profile. This ensures on the one hand that the insulation remains in positions and on the other hand makes opening the access door easier.

First, reference is made to the Fig. 1 showing a winding shaft box attached to an upper vertical rail or upper vertical strut 1 of a window frame. The winding shaft case in this case has an approximately U-shaped jacket 2, which is provided at its two front ends with side parts 11 on which a bottom board profile 8 is screwed from the outside. The floorboard profile 8 has for this purpose two screw channels 12 extending along the profile. The frame with the horizontal strut 1 is shown in a pointing with its outer side facing up, lying mounting position in the guide rails 3 on the frame are mounted, in which can accumulate on a winding shaft contained in the winding shaft box mounted curtain. At the vertical in the mounting position of the frame, in the installed position on the building upper side of the upper horizontal strut 1 while an adapter profile 7 is screwed, which is adapted to the wooden horizontal strut 1 by a flat underside, which corresponds to the flat top of the flat wooden strut , wherein on the adapter profile 7 of the winding shaft box is mounted with his floor board profile 8.

In the in Fig. 1 shown assembly position of the window frame below the floorboard profile 8, in the installed position shown in the window frame and the winding shaft box on the building, however, on the building inside, there is a revision flap 4. The inspection flap 4 closes an inspection opening of the box interior to the building inside. Since the box interior is connected via the outlet opening for the curtain with the outside of the building, a heat insulation is provided on the access panel 4, which consists of a board-like glued on the inspection panel 4 insulation layer 5 and a corner subsequent thereto additional insulation 6. At the bottom board profile 8 while a hold-down flag 9 is clipped, which is biased against the insulation layer 5 and thus supports an opening of the access door 4.

The in the Fig. 1 shown connection assembly consisting of the screwed onto the wooden frame adapter profile 7 and the floor board profile 8 is in the Figures 3 . 5 and 7 shown in different situations during assembly of the winding shaft box on the window frame, namely in an initial position when attaching the winding shaft box ( Fig. 3 ) in an intermediate position, in which the winding shaft box is during hooking ( FIG. 5 ) and in a hinged end position ( Fig. 7 ). The Figures 2 . 4 and 6 show in corresponding positions one of the same floor board profile 8 and a slightly modified adapter profile 17 existing connection assembly in the same assembly sequence. The adapter profile 17 has different than the adapter profile 7 on its side facing the window frame two Klipsleisten as Klipselemente on which it is clipped to locking lugs, which are provided on the formed as a plastic profile upper cross member 10 of an industrially manufactured plastic window, but otherwise differs from its bottom plate 20 ago and his the floorboard profile 8 side facing not from the Klipsprofil 7 for wooden windows.

The bottom board profile 8 in this case has two counter-engagement webs 21, 22, the engagement webs or projections 23, 24 are assigned, which protrude obliquely upwards to the floor board profile 8 at the attached to the window frame frame adapter profile 7 and 17, whereas the counter-engagement projections or . Webs 21, 22 of the floorboard profile 8 in the position shown, in which the winding shaft box is attached to the outside with its outside facing, lying frame, obliquely downward. The obliquely upward inner surface of the hooks formed by the engagement projections 23, 24 is planar and corresponds to the obliquely downwardly facing, planar inner surface of the hooks formed by the counter-engagement projections 21, 22. This results in an inclined plane, along which the box can slide on suspension assisted suspension, as in particular from the FIGS. 4 and 5 evident.

In this case, a security against slipping of the hinged box during or after the erection of the total unit formed from the window and the box is provided via a latching or securing mechanism. The securing device comprises a latching projection 27 provided on the upper engagement projection 23, to which a counter-latching projection 25 provided on the lower counter-engagement projection 22 is assigned. The locking projection 27 projects from the obliquely downwardly facing outside of the hook formed by the upper engagement projection 23 approximately at 90 ° angle and has the shape of a relatively short, but thick locking lug with a rounded tip. The counter-locking projection 25, however, is almost at a relatively steep angle vertically upwards from the lower counter-engagement projection 22 and has the shape of a narrow, compared to the latching nose shape of the locking projection 27 but relatively long leaf spring.

When sliding along the inclined plane of the leaf spring-like counter-locking projection 25 first comes into attack on the locking projection 27, as shown in the FIGS. 4 and 5 is shown and then springs before reaching the end position of the box in its bias-free end position in the rear grip on the locking projection 27. This ensures the desired security against sliding of the box.

At the lower counter-engagement projection 24, a sealing lip 26 is extruded, which presses in the end position against the bottom plate 20 of the adapter profile 7 and 17 and thus closes off a possible occurring due to manufacturing tolerances gap between floorboard profile 8 and adapter profile 7 windproof. Like in the Fig. 3 denoted by reference numeral 28 is also on the underside of the adapter profile 7 a sealing lip anextrudiert to seal a possible gap between the adapter profile 7 and the upper horizontal strut 1.

Furthermore, the floor board profile 8 has a flag web, designated 29, on which the hold-down tab 9 pressing on the insulating layer 5 on the access door 4 is clipped.

Advantageous modifications and modifications of the embodiments shown are possible without departing from the scope of the invention.

Thus, depending on the type of window frame, it is possible to adapt the clip elements provided (or not provided) for attachment thereto.

Furthermore, for example, for a roller shutter with external audit, so provided by an inspection opening on the outside of the building maintenance, which accordingly has no access door on the inside of the building, The hold-down flag for the inspection insulation and according to the flagpole are also omitted.

To connect the floorboard profile to the winding shaft box, other connection possibilities could also be provided on the floorboard profile-alternatively or in addition to the screw connection to the screw channels with the box side parts. For example, it would be conceivable to provide clip strips in order to clip them along the box to corresponding counter-clip elements on a further profile or on a box wall.
