Description

Frame with int. Magnetic mounting arrangement for attachment elementsDescription

The invention relates to a composite construction for closing a Gebäudeöffnnung, in particular windows, with a floor frame and a header frame, which is in each case formed from a frame made at the corners interconnected Profilab¬schnitten.

The attachment frame is formed from frame profiles, which form a tenter frame and a mesh fabric, which may for example consist of a fine-meshed fabric.

Increasingly, window systems are being constructed for insulation engineering purposes such that a stick-frame gasket (Figure 1) rests directly against the window glass, thus allowing the classical installation of conventional insect-protection systems with fold-over frame seams, e.g. metallic hooks is no longer possible without damaging the window glass.

The use of known mounting applications with hooks mounted on the insect screen frame, as are known, for example, from the patent applications DE 10032 170, DE 198 35 390, DE 40 16 421, EP 1433 920, DE 10 2005 000 692, is thus no longer possible without on the window glass to collide with various Metaleinhänge¬ flaps.

Conventional attachment frames can only be fastened to window frames by means of drilling, screwing or adhesive fixtures, but this has the disadvantage that after removal of the attachment frames damage to the frame can always occur.

The known from the prior art, usually metallic suspension elements on the attachment elements, moreover, there is the danger that in an improper assembly process, the floor frame of the window system is scratched.

A front door for insect protection is known from DE 10 2007 007 170 A1. The front door has a wing, which consists of a frame profile and a mesh fabric and can be pivotally attached to a door frame by means of a hinge joint. This attachment door has a magnetic element which can cooperate with a further magnet element attachable to the door frame to serve as a closure for the auxiliary door.

A similar attachment door is known from EP 1 520 953 B1, which also relates to a mitztels a hinged hinge pivotally arranged additional door with a Insek¬tengitter that can be kept closed by means of a magnetic closing part. If an additional frame is provided, the corresponding magnetic closing part can be received in the frame and encapsulated therein. The frame itself is to be attached to the door frame by means of screws.

Furthermore, from DE 383 960 (of June 16, 1921) and DE 20 2011 000 289U1 in size adjustable insect screens are known.

The invention is therefore based on the object of providing a composite construction which is suitable for closing a building opening surrounded by a floor frame, such as e.g. a window or a door, a header frame, so that the frame frame and the attachment frame no visibly arranged Halte¬rungen are attached and the attachment frame is releasably attachable to the floor frame, without leaving neither the floor nor the attachment frame tracks.

The object is achieved by a composite construction with the features of claim 1. Advantageous embodiments of the inventions are indicated in the subclaims.

The composite construction according to the invention for closing a building opening, in particular for closing a window or a door, comprises a frame bordering the building opening and an attachment frame provided with an insect screen. The composite construction is characterized in that magnets are arranged in the frame or in the attachment frame inside the respective frame and in the other frame magnetic elements are arranged, which cooperate with the magnets such that the attachment frame exclusively by means of the magnetic effect with the frame is ver¬bindbar.

Between the floor frame and the attachment frame are no mechanical connection elements such. As hinges or other joints provided. The attachment frame is held on the pole frame solely by the magnetic force. The attachment frame is thus releasably attachable to the floor frame. Such a composite construction is particularly suitable for dwellings with changing dwellers, as certain residents would like to have an insect screen with an insect screen, whereas other dwellers prefer not to close building openings with such insect screens. Since the magnets or magnetic elements are integrated into the floor frame of the window or the door, no measures must be taken on the floor frame of the window or the door in order to be able to attach a front frame according to the invention to it.

Preferably, the header frame has a tread edge that, when placed on a respective pole frame, rests against it so that the header frame is supported by the pole frame. This profile edge is typically formed on the lower transverse frame section of the attachment frame, which is supported on the lower transverse frame of the pole frame. As a result, a large part of the weighting force of the attachment frame is derived via the frame, so that the requirements for the magnetic force exerted by the magnets are kept low.

The magnetic element may be either another magnet or a ferromagnetic body that can interact with the magnet. The magnets and magnetic elements are arranged in such a way in the floor frame and the attachment frame, that they are opposite to each other and tighten when the attachment frame is attached to the pole frame.

The building opening is preferably a window having at least one glass pane, the glass pane being integrated in the floor frame.

The floor frame can be sealed off from the glass pane by means of a sealing element, in particular a sealing lip, which bears directly against the glass pane. This sealing lip is preferably an integral part of the Stock¬rahmens. The floor frame may have an integrally and non-releasably connected to the frame frame Blendrahmen on which the sealing lip is arranged such that a window sash in the closed state of the window rests with a Glas¬scheibe on the sealing lip.

The magnet and / or the magnetic element can be arranged in a recess in the frame and / or in the attachment frame. The recess may comprise a receptacle detachable on the respective frame, with which the magnet and / or the magnetic element can be fixed to the frame. The receptacle is designed in particular as a cap or cover and can be arranged flush with the surface of the frame. This makes it possible to arrange the magnet and / or the magneti¬sche element on the floor frame, if this is already integrated in a building. The receptacle preferably has locking means which form a latching connection with the corresponding frame, so that the receptacle can be clipped together with the magnets and / or together with the magnetic element in the frame or in the attachment frame.

The magnets and the magnetic elements are preferably arranged in the respective frame adjacent to the wall facing the respective other frame.

The floor frame may have a closed or partially open profile contour.

On the attachment frame, a carrying handle may be arranged so as to simply attach the attachment frame to the building opening or to remove it again.

The holding force of the attachment element on the pole frame is generated by the magnetic force of the opposing magnets in profile frames of the attachment element and of the frame.

The magnets on the floor frame are ideally arranged so that they are located in a splash-proof zone or else also a hollow chamber, can be fixedly connected to the floor frame or, due to the design, can be attached to contoured profile contours.

Likewise, the attachment of the magnets to their own holding / support parts is possible, which are preferably attached / installed on the splash-proof zones of the floor frame.

The attachment of the magnets and / or magnetic elements to the attachment frame is to be done in the same manner as on the frame.

An additional advantage of the system results from the fact that the attachment frame can be statically kept smaller in the profile cross-sections compared to known systems, since this must be stabilized by the peripheral magnetic holding force on the window frame and thus not self-supporting, which in turn beigeringen space-based installation situations eg between roller shutter and window mitgeringem distance allows a narrow insect screen frame arrangement.

A groundbreaking mounting relief over known systems results in that when attaching the attachment element on the floor frame, which must be mounted mostly from the inside of the room on the outside of the window, this moves automatically already at a distance of several centimeters by the attraction of the magnets, the final position.

The magnetic holding force of the attachment frame to the pole frame may optionally be provided with two opposing magnets in north-south polarity, as well as with a magnet and a magnetic element, such as e.g. a ferromagnetic metal part.

In the attachment method according to the invention an attachment door on Stockrah¬men the magnets are preferably designed as permanent magnets, in particular neodymium magnets.

Such magnets have the advantage that their magnetization practically does not change during a long period of time.

The attachment frame can be mounted and dismounted via the profile frame as well as via handles attached thereto.

Magnets and at the same time magnetic elements which are not magnets can also be provided on a header frame and / or on a pole frame, if, corresponding to other frames, a respective magnet is associated with the magnetic elements, which are not magnets.

Further advantages and details will be explained by means of embodiments with reference to the figures.

FIG. 1 is a view, cut in the vertical direction, of a magnetically supported attachment frame 1 on a pole frame 8 with concealed magnets 6 + 7.

A composite construction according to the present invention is used for closing a building opening 2, such. As a window or a door. In the attached figures, a window with a window floor 3 and a window sash 4 is shown as an exemplary embodiment of the building opening. The window stock 3 is conventionally mounted in the building opening 2. The window sash 4 is pivotally mounted on the window stock 3. In the present exemplary embodiment (FIG. 1), the window sash 4 has a triple glazing with three glass panes 19, which are an integral part of the window sash 4. Seals are provided on the window sash or on the window sill 3 in a manner known per se in order to seal the window sash 4 with respect to the window sill 3. The window stock 3 has a base body to which a frame-shaped header 8 is attached. The attachment shell 8 is an integral part of the window stock 3 and not lösbarer connected to the body. The front shell 8 has a Flohlkammer 8a, which is formed on the window frame 3 circumferentially. In the area of the floc chamber 8a, a sealing lip 20 is arranged on the side facing the window sash 4, which, in the closed state of the window, rests against the outside glass pane 19 in order to additionally seal the window sash 4 with respect to the window sill 3.

At a lower cross member of the window frame 3, a weather rail 11 and on the inside of a window sill 12 are arranged in a conventional manner on the outside.

The attachment frame 1 is formed from profile sections, which has a groove for receiving a welt 9 in the inner region, with which an insect protection fabric 10 acting as an insect screen is attached to the attachment frame 1. In the embodiments shown in Figures 1 and 2, the Profil¬abschnitte are formed with two Flohlkammern 5a, 5c. The Flohlkammer 5c is an¬ grenzend to the groove for receiving the welt 9 arranged. The Flohlkammer 5a is arranged radially outside the Flohlkammer 5b. The Flohlkammer 5c is wider in cross-section than the Flohlkammer 5a and projects slightly inwards, so that it either directly a profile edge 5b (Figure 1) or indirectly by means of an additional profile web forms a profile edge 5b (Figure 2). The profile edge 5b projecting in the direction of the window sash 4 on the attachment frame serves to bear against the window sill 3 and, in the present exemplary embodiment, in particular on the attachment shell 8.

In the hollow chamber 5 a of the attachment shell 8 magnets 7 are arranged. The attachment shell 8, like the attachment frame 1, has a circumferential hollow chamber 8a in which corresponding magnets 6 are arranged. These magnets 6 are fixed in the hollow chamber 8a by suitable profile webs 8b in their position adjacent to the wall of the attachment shell 8 facing the attachment frame 1.

The attachment frame 1 can be placed on the window stock 3 with its attachment shell 8 such that the magnets of the attachment frame 5 and the magnets of the window stock 3 attract each other and fix the attachment frame 1 to the window stock 3. In this case, the profile edge 5b rests on the lower cross member of the window stock 3 such that a large part of the weight force of the attachment frame is introduced into the window stock 3 via this profile edge 5b.

In principle, however, it is also possible, without such a profile edge 5b, to fix an attachment frame on the window stock 3 exclusively by means of magnetic forces, where the attachment frame 1 is then held by a combination of the magnetic forces and a frictional engagement of the surfaces lying against one another.

For reasons of insulation technology, the glass pane in the window sash 4 is preferably sealed by means of a rubber strip fastened to the floor frame 8.

The attachment frame 1 is preferably provided with an insect protection fabric 10 fixed by a rubber spring 9 for protection against insects. The insect protection fabric forms an insect screen.

In the present embodiment, the magnets 6 + 7 are arranged in the pole frame 8 and the header frame profile 5 so as to be at least selectively positioned so as to face each of a south pole 6a and a north pole 7b to provide the required holding force.

However, it is also possible to use only one magnet 6 or 7 on one and one ferromagnetic, in particular iron-containing, metal on the other side, between the frame frame and the attachment frame, in order to generate the magnetic closing force.

Fig. 2 shows the horizontal section of another embodiment in the assembled state. The sectional views of the floor frame 3 + 8 and attachment frame profiles 5 and the components arranged therein.

3 shows a horizontal section of a further exemplary embodiment in the mounted state in the case of a special profile with insulating foam behind the protected outer shell of e.g. aluminum

2 shows how the magnets 6 + 7 should be arranged on the pole frame 8 and attachment frame profile 5 in their polarity 6a + 6b, 7a + 7b in order to be able to generate the magnetic holding force caused by this. The reference numerals 6a and 7a indicate the north and 6b and 7b the south pole.

The magnets 7 of the attachment frame profiles 5 are arranged in a closed hollow chamber 5a, in order to protect them against weather-related environmental influences, which also applies to the same extent to the magnets 6 in the hollow chamber 8a in the frame 8.

The magnets, in particular of the floor frame, but can also be attached to own Trä-ger / holding parts.

These parts may also be attached to the appropriate positions only occasionally in the splash-proof zones of the hanger profile on both the space and the outside.

In order not to fully absorb the dead weight of the attachment frame 1 by the magnet 7 in the attachment frame profile 5 and the magnet 6 in the frame 8, it is proposed to load the load via a profiled edge 5b, as shown in FIG. 1, on the hollow profile is formed, or can be ausgebil¬det on an additional profile web (Fig. 2) to support the attachment frame profile 5 on the floor frame 8.

The profile web 5b according to FIG. 2 extends from the attachment frame 1 in the direction of the frame 3.

In the exemplary embodiment shown in FIGS. 4a-4c, in turn, an attachment frame 1 can be fixed to a window stock 3 exclusively by means of magnetic forces. Here, the window stock 3 on the inside has a recess 16, in which a magnet 6 together with a magnet holder 13 can be arranged such that the magnet 6 is fixed in position in the window frame 3. The magnet holder 13 is formed in the shape of a cap which encloses the magnet 6 with a small clearance. In the magnet holder 13, there is disposed a compression spring 15 which presses the magnet 6 against the outer wall of the window stock 3. For this purpose, the magnet holder 13 has a compression spring receptacle 18. On the outer surface of the cap-shaped Mag¬nethalters 13 locking lugs 17 are formed, with which the magnet holder 13 is fixable in the recess 16.

With such a design of the window stock 3, a magnet 6 can subsequently be inserted into the window stock 3 without the window stock 3 having to be altered or damaged thereby. The recess 16 is arranged on the inside of the window stock 3 and thus on a splash-proof area of the window stock 3.
