Description

The invention relates to a window or a door according to the preamble of claim 1.

Windows or doors according to the preamble of claim 1 are known from EP 1403457 B1 already known. Such a window is provided with a turn, tilt and / or turn-tilt hardware. This fitting allows the wing to pivot about different axes with respect to the frame. Wing and frame are connected to each other via hinges and locking elements. In order to avoid in case of failure of one of the hinge parts that the wing falls out of the frame by omission of the axis and injured example, a person, it is provided that the rotation axis side a fuse element holds the wing to the frame. The security element is a flexible and in the normal operation of the window or the door unloaded rope.

The ends of the rope are attached to the wing and frame over two differently shaped brackets in each fold. The brackets must, in order not to restrict the limited space between the sash and frame, offset from each other and each have the rope-tightening winder on.

Such a window or a door with such a fitting is also from the EP 2159360 A2 , which discloses all features of the preamble of claim 1, known. In this case, a fitting system for windows or doors with trained between frame and sash rotation, tilt and / or turn-tilt axis is disclosed, which at least from a faceplate guided drive rod, locking elements, closing parts and / or at least one Ausstellschere existing arrangement for switching of the fitting system has on different effective axes, with rotation axis side between the wing and frame and this frame held rupture resistant at least one flexible, dormant in normal operation of the fitting system and outside the allowable nominal positions of the Wing is effective relative to the frame effective expectant security element is provided in a tear-resistant design. On this basis, the ends of the rope provided as a securing element are made thickened and the diameter is larger than the holes of mounting plates, which passes through the rope. Furthermore, a spring element is known, which tensions the rope, so that it comes to a reduced kinetic energy when the thus provided with a lesser degree rope is claimed to train.

The invention has for its object to provide a window or a door in which a particularly simple and cost-effective security element is provided, which is no impairment of the normal function and holds the wing on the frame at a failure of the fitting system.

To achieve this object, the invention consists of a window or a door with a securing element according to claim 1. Preferably, the element is made of an elastic material, for example of a plastic material or of a metallic material, which is coated with a plastic material or a rubber material, manufactured. It is also conceivable that the element is made only of a metallic material.

In order to reduce the collection of the wing and thus the speed of movement in a possible failure of the hinge components controlled upon impact of the element and with sufficient kinetic energy, the abutment stages are plastically deformable, so that by successively arranged at a distance abutment stages, a gradual reduction of kinetic energy is effected. The attenuating section, which at the same time can also be called, reduces the momentum of the impact load.

In order to achieve the simplest possible embodiment of the securing element, which can simultaneously generate a resistance by means of a positional fixation, a thickening is arranged at the ends of the rope whose dimension is matched to the clear dimension of the abutment arranged cylindrical receptacle or the guide, so the thickening in this movement is almost free of play and has a stop limit for effecting movement limitation. The thickening may have a cylindrical shape or be formed as a ball.

The securing element is designed so that the cylindrical receptacle is arranged on the abutment on the side remote from the wing or frame side, which is penetrated by the cable, wherein in the receptacle, the abutment steps are mounted. The visible side of the receptacle allows easy assembly or disassembly of the rope to the abutment without the abutment of the wing or the frame to solve. Furthermore, the abutment is flat on the side of the wing or frame, which allows installation without costly editing, such as milling on the wing or frame. Furthermore, the cylindrical receptacle extends in the longitudinal direction of the abutment, each with open ends.

If a thickening is attached to each end of the rope, the rope can be designed mirror-symmetrically. This simplifies the assembly, which can be done without confusion and reduces the number of components and machines required for the production on the one hand.

A further embodiment provides that each end of the rope is associated with an abutment and that the abutment are identical, so that the entire fuse element is mirror-symmetrical.

For space-saving storage of the rope and for easy installation in the abutment which is remote from the abutment stages end for introducing the thickening of the rope corresponds to the inner diameter of the cylindrical receptacle. In addition, the opposite end of the abutment stages adjacent to the rope closely encompassing adapted diameter-reducing opening, which holds the thickening under load as an end stop forming captives. In the cylindrical receptacle, the rope is thus fixed in its inactive position.

In order to make use of the space between the sash and the frame and to allow the installation of the rope from the freely accessible side of the abutment, it is further provided that the abutment consists of a substantially flat plate and the receptacle, wherein extending in the longitudinal direction the entire length on the plate remote free side of the cylindrical receptacle extends a gap opening, which is tuned in the width of the diameter of the rope so that the rope is pulled through.

To achieve a large escape resistance and simplified positioning of the securing element is provided that the plate on the side facing the wing or frame side has a pin and to which is provided for receiving fasteners, not shown, for example, fastening screws, provided bore a cylindrical reinforcement. It can also be useful to use a drilling jig to help the bore for joining the pin and the cylindrical reinforcement on the wing and the frame. Depending on the load, the pin and the cylindrical reinforcement can vary in length, which increases the mechanical load capacity.

In order for one and the same securing element to be used in the case of a plurality of profiles, in particular for plastic profiles, shims are provided on the wing and / or on the frame which already have prefabricated recesses on the side for the abutment for the positive engagement for the pin and for the cylindrical reinforcement.

The space-saving design of the securing element proves to be particularly advantageous that the securing element is arranged concealed in the rebate of the wing and the frame. The hidden position is also made possible by the fact that the cable runs in an adjacent position of the wing to the frame almost congruent in the longitudinal direction of the fitting groove of the espagnolette in the rebate.

To save costs and simplify the production, the abutment is preferably made of a die-cast material.

For the basic function of the fuse element 1 and its interaction with the window or the door is on the EP 1403457 B1 to which reference is made in full. In the Fig. 1 a securing element 1 is shown, which consists of a rope 2 and two abutments 3, 4. In the illustrated embodiment, the abutments 3, 4 are formed as flat plates 21, which have a pin 5 and a cylindrical reinforcement 22 for adjusting the assembly on the side facing the wing 15 or frame 16 side, wherein the cylindrical reinforcement 22 by means not shown fasteners For example, fastening screws are penetrated in holes provided for this purpose 6. The abutments 3, 4 are identical and are penetrated by the cable 2 in a cylindrical receptacle 7, which is arranged on the side facing away from the wing 15 or frame 16 side. The cylindrical receptacle 7 extends in the longitudinal direction of the abutment 3, 4. Here, the cylindrical receptacle 7 is lined in the inner diameter so that it provides the cable 2 a nearly play-free guide 8.

The consisting of the rope 2 and the abutment 3, 4 fuse element 1 comprises after Fig. 2 preferably an element 9, which is associated with at least one frame-side and a wing-side abutment 3, 4, wherein at least one of the abutments 3, 4, a number of in the direction of the effectively claimed rope 2 at least one advantageously two or more consecutively arranged abutment stages 10th has predetermined breaking points at which the element 9 is supported. The abutment stages 10 are arranged in the inner diameter of the cylindrical receptacle 7 and form in the free space facing webs. Depending on the embodiment, the webs may take the form of a ring circumferentially per step, which form an abutment step 10. To form a predetermined breaking point, the connection of the webs to the inner diameter of the cylindrical receptacle 7 is material-reduced, for example, configured by a taper. The element 9 may be made of an elastic material, for example of a plastic material or of a metallic material, which is coated with a plastic material or a rubber material is to be made. However, it is also conceivable to produce the element 9 only from a metallic material.

By the successively arranged at a distance abutment stages 10 after Fig. 1 can be achieved in a failure of the hinge components, not shown, a catching of the wing 15 and thus a controlled reduction of the speed of movement. By acting on the element 9 and with sufficient kinetic energy, the abutment steps 10 are plastically deformable, thus effecting a gradual reduction of the kinetic energy by means of the abutment steps 10 arranged successively at a distance. The attenuating section, which at the same time can also be called, thus reduces the momentum of the impact load.

When loading the fuse element 1, a resistance builds up by means of a bearing fixation, which after Fig. 2 and Fig. 5 is formed by a arranged at the ends 11, 12 of the cable 2 thickening 13, 14, whose dimension is matched to the clear dimension of the abutment 3, 4 arranged cylindrical receptacle 7 and the guide 8, so that the thickening 13, 14 in this almost free of play is movable and has a stop limiting the movement limiting.

If at each end 11, 12 of the rope 2, a thickening 13, 14 is attached, the rope 2 can be designed mirror-symmetrically. This simplifies the assembly, which can be done without confusion and reduces the number of components and machines required for the production on the one hand.

To Fig. 1 It is shown that at each end 11, 12 of the rope 2, an abutment 3, 4 is assigned and that the abutments 3, 4 are identical, so that the entire fuse element 1 is mirror-symmetrical.

The Fig. 3 and Fig. 4 shows the wing / frame assembly 15, 16 in a sectional view indicating the turn-tilt axis 17, wherein the spars are formed as profile bars. Likewise, a wing and frame made of a wood or light metal profile can be used. The wing 15 is pivotable relative to the frame 16 about an axis 17. The axis 17 is formed by a hinge, not shown here, which is part of a fitting of the window. Between wing 15 and frame 16 next to other fitting parts of the window are effective, which may be part of an espagnolette fitting, which is arranged between the frame 16 and wings 15 and about the different axes 17 can be adjusted. From the Fig. 3 it becomes clear that that Securing element 1 is mounted on the rotation axis side between the wing 15 and frame 16. It is envisaged that the fuse element 1 is initially inoperative during normal operation of the fitting and is effective only outside a permissible target position of the wing 15 relative to the frame 16.

The securing element 1 is designed such that the cylindrical receptacle 7 is arranged on the abutment 3, 4 on the side facing away from the wing 15 or frame 16. In this position, the receptacle 7 is penetrated by the rope 2. Furthermore, in the receptacle 7, the abutment steps 10 are shown attached. The visible side of the receptacle 7 allows easy assembly or disassembly of the rope 2 to the abutment 3, 4 without the abutment 3, 4 from the wing 15 or the frame 16 to solve. Further, the abutment 3, 4 on the side of the wing 15 or frame 16 is formed flat, which allows mounting without costly processing, for example, milling on the wing 15 or frame 16.

For space-saving storage of the rope 2 and for easy installation in the abutment 3, 4, the cylindrical receptacle 7 extends after Fig. 1 in the longitudinal direction of the abutment 3, 4, each with open ends 18, 19, wherein the distal end of the abutment stages 10 18 for inserting the thickening 13, 14 of the rope 2 corresponds to the inner diameter of the cylindrical receptacle 7 and wherein the abutment steps 10 opposite adjacent end 19 after Fig. 2 a diameter of the rope 2 closely matched diameter-reducing opening 20, which holds the thickening 13, 14 secured under load. In the cylindrical receptacle 7, the rope 2 is thus fixed in its inactive position.

To the rebate 24 between the wing 15 and frame 16 after Fig. 3 to make use of and to allow the installation of the rope 2 from the freely accessible side of the abutment 3, 4, is further according to the perspective exploded view of Fig. 2 provided that the abutment 3, 4 consists of a substantially flat plate 21 and the receptacle 7, wherein in the longitudinal direction over the entire length on the plate 21 remote free side of the cylindrical receptacle 7 from the end 18 to the end 19, a gap opening 26th extends, which is matched in width to the diameter of the rope 2 so that the cable 2 is pulled through.

The detailed representation in the section to Fig. 5 shows the fuse element 1 with the plate 21, which has a pin 5 on the side directed toward the wing 15 or frame 16 and a cylindrical reinforcement 22 is provided on the bore 6 provided for receiving 7 of fasteners, not shown, for example fastening screws. Thus, a large escape resistance and a simplified positioning of the fuse element 1 are achieved. Conveniently, a drilling jig to help the bore for joining the pin 5 and the cylindrical reinforcement 22 on the wing 15 and the frame 16 can be used. Depending on the load, the pin 5 and the cylindrical reinforcement 22 may vary in length, which increases the mechanical strength.

So that one and the same securing element 1 can be used in the case of a large number of profiles, especially in the case of plastic profiles, as in FIG Fig. 2 and Fig. 3 Shown on the wing 15 and / or on the frame 16 according to shims 23 provided on the side of the abutment 3, 4 not already shown in the drawing prefabricated recesses for positive engagement for the pin 5 and the cylindrical reinforcement 22.

Furthermore, it should be noted that the design of the fuse element 1 proves to be space-saving and concealed in the rebate 24 of the wing 15 and the frame 16 is arranged. The hidden position is also made possible by the fact that the cable 2 in the adjacent position of the wing 15 to the frame 16 extends almost congruently in the longitudinal direction of the fitting groove 25 of the espagnolette in the rebate 24.

Finally, reference is made to the design of the abutment 3, 4, that by the way of the designed component after Fig. 1 and Fig. 2 makes it particularly simple and thus inexpensive to produce when the abutment 3, 4 is produced by a die-casting process. This makes it possible to selectively replace possible edges in the case of transitions through radii, which otherwise offer the risk of material fractures. In particular, this feature has a positive effect on the expected forces occurring during a load of the fuse element 1.
