Austrian Patent Application No. 77 350 774 further discloses a shutter cabinet comprising an intermediate fastener that can be fastened to a window frame in which the intermediate fastener is pushed into the sectional leg of a fastening wall element. The fixed position of the retaining wall member and the intermediate connector is locked by a locking member introduced into the groove to prevent the locking of the shutter and the intermediate connector.

Further structures for attaching an additional roller shutter cabinet to a window frame section are also described in EP 1 710 388 A1 and EP 0 848 912 B1.

Based on the published structural solution DE 295 2Ö 504 Ul, the object of the present invention is to provide a connection structure for additional roller shutters which, in addition to being easy to install, also facilitates subsequent renovation works,

To accomplish the object of claim 1, a fastening and non-destructive connection is provided between the connecting lower member and the base section. Preferably, at least one clip is provided for such connection.

Thanks to this solution, the additional roller shutter can be easily mounted on the window frame section, creating a fast and releasable connection between them. In this way, window replacement, for example in the event of a subsequent renovation of the building, can be carried out quickly and with little effort without destroying the base of the accessory shutter. During the renovation, the additional roller shutter can remain blinded, eliminating the need for removal, which results in significant time savings. Since the bottom bracket is not damaged when replacing the window frame section, it may be sufficient, if necessary, to have only the base section and the window frame section connection to the additional roller shutter ♦ »♦ suitable for all windows and the production window same

The connecting lower element may be formed as a integral part of the base of the auxiliary shutters. However, it has proven to be advantageous if the connecting lower member is configured as a separate bottom profile insert from the bottom plate. In this way, the advantageous, re-releaseable connection between the window frame section and the additional roller shutter can be achieved without changing the cost of the additional roller shutter manufacturing operation.

For example, a structural arrangement may be advantageous in that at least one catching element protruding from the outside edge of the connecting lower window towards the base section, the base section having at least one receiving groove associated with the catching member and having a rear shoulder and the connecting lower member has a cooperative extension of the rear shoulder. Thanks to such a design, the connecting rear member can be easily connected to the base profile with non-destructive solubility of the coupling between the sections.

Advantageously, the connection between the separate connecting member formed as a separate structural element and the housing section is achieved by placing the additional shutter box with the connecting member on top of the profile section with the base section and then perpendicular to the surface of the window glass. For this purpose, it is advantageous to use a clamping body which secures and secures a protrusion of the projection of the connecting lower element and a protruding part of the rear shoulder of the base section. Thus, the additional roller shutter can be attached to the window frame section without much effort and the locking between them can be released at any time by removing the clip.

It has been found advantageous to have a notch on the opposing surfaces of the projections and on the faces of the clamping element facing the projections to provide a solid, yet resolvable, connection between the attachment lower member and the base section.

Advantageously, the base section is provided with legs with locking nails extending below the recesses delimiting the groove in the upper side of the window frame. With the locking nails on both sides of the base section, the base section simply clicks without the need for additional accessories such as bolts! easy and fast to connect and install. window frame for profile. Particularly, for example, in the case of wooden window sections, screw fastenings can be used as an alternative or even combined method for connecting the base section and the window frame section.

The base section and the connecting bottom member are preferably made of plastic, optionally various plastics.

Other preferred embodiments of the invention may be deduced from the following subclaims. Any combination of features that can provide a meaningful solution is talented.

In the following, a preferred embodiment of the invention will be based on the accompanying drawings

Figure 4 is a sectional view of an additional roller shutter attached to the window frame section.

Figure 1 shows a section of a window frame 1 to be connected to an additional roller shutter 10 (shown in Figure 3) of a window. A base section 2, preferably made of plastic, is used for the connection. Such a structural material is light in weight and can be produced at a lower cost than metal materials. The base panel 2 extends over the entire window width and has an upper panel 3 and a lower panel 5 spaced therefrom by ribs 4. The chamber cavities resulting from this design also serve to accommodate the heads of recessed screws 8 in addition to weight reduction, as will be described below.

According to a first embodiment, the bottom panel 5 sits flat, facing the window frame section 1. has a flat surface. In contrast, the upwardly facing surface of the top panel 3 of the base assembly 2 is provided with grooves 8 transverse to the window (extending along the top frame of the section frame 1), which, like the base assembly 2, extend over the entire width of the window. At least one abutment 7 is formed in the lateral region of the base panel 2 outside the window. To connect the base frame 2 and the window frame section 1, the base section 2 is placed on the window frame section 1 with the operation shown by an arrow so that the stop 7 lies exactly on the side surface of the window frame section 1. The stop 7 thus serves as a mounting aid. In order to establish a fixed connection between said structural members, the base section 2 is fastened to the window section 1 with screws 8. The insertion points of the screws 8 are defined by the grooves 8, so that the screws 8 are screwed into the base section 2 at predetermined spaced distances for fixing the window frame section. Recessed head screws are preferably used, since they can be folded into the base section 2 in their entirety and thus retain the flat surface of the top panel 3 of the base section 2. This connection method is preferably used for the wooden window frame sections 1.

Another embodiment of the connection between the base section 2 and the window frame section 1 is shown in FIG. In this exemplary embodiment, the base section 2 also has foot pins 9 with locking nails on the underside 5 of the base section. The feet 9 are structural members associated with the bottom sheet 5 and are perpendicular to the bottom sheet 5. To connect the base section 2 to the window frame section 1, the base section 2 is placed on the window section section 1 in the same way as in the direction of the arrow. however, in the embodiment, the locking nose feet 9 engage in the lower notches of a groove formed on the upper side of the window frame, thereby engaging the elements. The locking nuts snap into the undercuts without the need for additional mounting aids and mounting tools. In this case it is not necessary, but it is also possible to use screw joints between the base section 2 and the window frame section 1 if desired. Such a connection is particularly advantageous for plastic window frame sections 1, whereby the snap-locking of the base section 2 is also facilitated by the resilient material properties of the plastic.

The base sections 2 as shown in Figures 1 and 2 are independent of the inward facing thickness of the window frame section 1. This means that, regardless of the thickness of the window frame section 1, the same base section 2 can be applied to almost all windows. As a result, there is no need to produce 2 custom-made base sections per window type. This reduces production and material costs.

After placing the base section 2 on the window frame section 1 and securing it securely, in a subsequent operation step the additional roller shutter 10 is connected to the window section section 1 as shown in FIG. Connecting the additional 18 roller shutter casing of the one frame section 2 base coupon comprises, according to a possible embodiment related additional 10 roller shutter bottom 12 face material, but preferably the current exemplary According solution embodiment includes a discrete from 11 engaging the lower member, hereinafter referred to as the bottom face 11 _v «« »« «*« ♦ X «0 *« x * x <·. ♦ «· ·· ♦» <* «» «*» # * 4 X · »4> ♦ <* * φ 4χ φ *> ^ 4 ** 4 «χ« 4 * «*« & 4 '«« * «4 V * *« »X is a structural thread known as an adapter. The bottom flap fitting 11 is inserted into the retaining groove 12 of the bottom flap 12 of the auxiliary shutters 10, and is secured therewith by the engaging elements. At a lateral exterior edge, the bottom flap adapter section 11 is provided with at least one inwardly facing auxiliary engaging member 13, while a transverse interior end portion is joined by a stepped ridge which engages with the bottom flap 12 in occupies a position parallel to its base

To connect the base plate 11 to the base frame 2 of the window frame 1, the additional shutter 10 with the base plate 11 is placed from above on the base 2, as shown in Figure 3. After being mounted, the base plate 11 is perpendicular to the glass unit (shifted in the direction of the arrow as shown in Figure 3). In doing so, the preformation hook 13 of the bottom panel fitting 11 is inserted into a groove 15 or recess 15 formed in the base section 2, while the inner projection 14 of the bottom panel fitting window 11 is positioned to accommodate a window base 2. stepped shoulder 10 on the inside edge. Thus, the position of the auxiliary roller shutter 10 relative to the base section 2 of the window is fixed in a horizontal direction, while the bottom panel fitting 11 can be moved or removed from the vertical in the direction indicated by a dashed arrow on the inside of the window.

To prevent the additional roller shutter 10 from slipping, a

In the retracted state, it engages a protruding portion of the projection 14 of the base plate 11 and a protruding portion of the rear shoulder 16 of the base plate 11, and secures and connects the 11 to each other without the need for screwing. and 2 coupons. The clamping element 17 is pushed into the recess formed for this purpose until its mounting stop 18 protruding in the window direction rests on the inner surface of the section 1 of the window frame.

In addition to reliably securing the auxiliary roller shutter 10 to the window frame section, to provide adequate protection against draft and heat loss, the elastic member 17 may be provided with an additional wiping lip 19 or other similar top member, and the elastic member 17 may also have teeth in which case the teeth engage the respective teeth of the base plate 11 and base 2. The teeth of the sections 11 and 2 are respectively formed on the facing faces of the projections. This prevents any unwanted release of the connection between the sections 2 and 11, even in the event of a window opening.

It is, of course, also possible to use a plurality of small stepping elements to individually join the affected sections across the entire width of the window frame section 1. However, it has proved advantageous to provide a clamping element 17 which completely fills the gap between the base plate 12 and the window frame section 1 and extends over the entire window width as a continuous element. This gives an additional wiping effect.

After the additional shutter 10 and the window frame section 1 are connected by means of the sections 2 and 11, the window with the additional shutter 10 can be inserted into the window opening of the building wall. Thus, especially in the case of prefabricated structures, there is no need for the individual or additional installation of the additional 10 roller shutters, which

The additional 10 roller shutters installed can be plastered together with the plastering of the building.

It is particularly advantageous to design and use the joining structure to carry out repair work such as replacing glass panes or even the entire window. A window for the additional 10 wardrobes! To remove it, the clip 17, inserted from the inside of the window, is pulled away from the protrusions of the base plate 11 and base 2. Thereafter, the window, together with the window frame section 1 (as indicated by the arrow in the lower region of the window frame section 1 in FIG. 3), can be hinged inwardly and outwardly in the upper region of the window. Meanwhile, the bottom plate fitting 11 remains non-destructively secured in the recess 12 of the bottom plate 12 of the additional shutter. The base section 2 is also non-destructively coupled to the window frame section 1, although it may be necessary to remove the base section 2 from the window section section 1 to perform window upgrades. If the base section is bolted to the window frame section 1, it is possible, for example, for another window section section, to use the base section 2 repeatedly.

Such a connecting structure between the bottom panel 12 and the window frame section 1 allows for the non-destructive separation of the section window window section section 1 from the additional roller shutter 10. Furthermore, it is not necessary to remove the additional roller shutter 10 for repair work on the window. This eliminates the need for operations such as repackaging the auxiliary roller shutter 10 after the window replacement. This significantly simplifies the replacement of the windows, reduces installation costs and saves costs.

For the additional 10 shutters. With respect to the attachment, the bottom plate adapter 11 may also be configured so that the additional plate 10 may be provided
