DESCRIPTION

Door or window with a hardware

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

Doors or windows according to the preamble of claim 1 are already known from EP 1403457 B1. A window of this type is provided with a turning hardware, a tilting hardware and / or a tilting and turning hardware. Through this fitting it is possible to rotate the blade in relation to the frame around different axes. To this end, the leaf and the frame are joined together by hinges and interlocking elements. To, in case of a failure of one of the hinge parts, prevent the blade from leaving the frame due to a detachment of the shaft and for example injuring a person, it is provided that, on the side of the axis of rotation, a security element fasten the sheet to the frame. The safety element is a flexible cable and, during normal operation of the window or door, not under load.

The ends of the cable are fixed to the sheet and to the frame by means of two fasteners of different configuration in the respective renewal. In order not to reduce the limited clearance between the sheet and the frame, the fasteners must be mounted offset with respect to each other and respectively have winding devices that tension the cable.

A door or a window of this type with a hardware of this type is also known from EP 2159360 A2, which discloses all the features of the preamble of claim 1. This document discloses a hardware system for doors or windows with a pivot, tilt and / or tilt-and-turn axis that is configured between the frame and the leaf and which has at least one arrangement composed of a connecting rod guided by lap rails, latch elements, of closing parts and / or at least one folding scissors to switch the axle fitting system of different effect, being provided on the side of the axis of rotation, between the blade and the frame and fixedly attached to this frame against the start-up, at least one flexible safety element configured in a way that is resistant to breakage, which does not have any function during normal operation of the hardware and which is activated outside the permissible nominal positions of the ho ha in relation to the frame. Starting from this, the ends of the cable provided as a safety element are made thickened and the diameter is greater than the holes of some fixing plates that the cable crosses. In addition, a spring element is known which tensiones the cable, so that reduced kinetic energy is produced when the cable, which thus has less play, is subjected to traction.

The invention aims to make available a door or a window in which a security element is provided that has a very simple configuration, is economical, does not impair normal operation and fastens the sheet to the frame in case of a failure of the hardware system.

To achieve this objective, the invention consists of a door or a window with a security element according to claim 1.

In this context, the element is preferably manufactured in an elastic material, for example in a plastic material or in a metallic material that is coated with a plastic material or with a rubber material. However, it is also imaginable that the element is manufactured only in a metallic material.

To brake the blade and therefore reduce the speed of movement in a controlled manner in case of a possible failure of the hinge components, the counter-support steps can be deformed plastically in case of a load on the element and with an energy sufficient kinetics, so that, by means of the counter-support steps arranged one after the other at a certain distance, a gradual decrease in kinetic energy is caused. At the same time, what can also be called the buffer section reduces the impact load impact. In order to achieve the simplest possible configuration of the safety element, which at the same time can produce a resistance by fixing the position, a thickening is arranged at the ends of the cable whose dimensions are adapted to the internal measurement of the guide or the cylindrical housing arranged in the counter-support, so that the thickening can move in the same or in the same almost without play and has a stop edge that causes a limitation of movement. The thickening may have a cylindrical shape or also be configured as a sphere.

The safety element is configured so that the cylindrical housing that is pierced by the cable is arranged on the counter-support, opposite the leaf or the frame, the counter-support steps being mounted in the housing. The visible side of the housing allows easy assembly or disassembly of the cable with respect to the counter-support, without releasing the counter-supports of the sheet or frame. In addition, the counter-support is configured flat on the side facing the sheet or towards the frame, which allows assembly without costly processing, for example milling work on the sheet or on the frame. In addition, the cylindrical housing extends in the longitudinal direction of the counter-support with respectively open ends.

If thickening is placed at each end of the cable, the cable can be configured with specular symmetry. This simplifies on the one hand the assembly, which can be carried out without any risk of confusion, and on the other hand reduces the number of components and machines necessary for manufacturing.

A refinement provides that each end of the cable has a counter-support assigned and that the counter-supports have an identical configuration, so that the entire safety element has specular symmetry.

So that the cable can be stored saving space and for easy mounting on the counter-support, the end that is away from the counter-support steps and intended for the introduction of the thickening of the cable corresponds to the inner diameter of the cylindrical housing. In addition, the end adjacent to the counter-support steps in front of them has a diameter reducing opening, which is adapted to wrap

tightly the cable and, in case of loading, hold the grease securing it as a final stop. Thus, the cable is fixed in the cylindrical housing also in its inactive position.

In order to take advantage of the free space between the sheet and the frame and enable the cable to be mounted from the freely accessible side of the counter-support, it is also provided that the counter-support is composed of an essentially flat plate and of the housing, extending in the longitudinal direction , along the entire length of the free side of the cylindrical housing that is away from the plate, a slit-shaped opening that is adapted in width to the diameter of the cable such that the cable can be passed through the same.

In order to achieve a high resistance to starting and a simplified positioning of the safety element, it is provided that the plate has a pin on the side facing the sheet or towards the frame and that in the hole provided for the accommodation of fasteners not shown , for example fixing screws, a cylindrical reinforcement is provided. In this context, an interior gauge can also be conveniently used as an aid for the drill in order to fit the spike and for the cylindrical reinforcement in the blade and in the frame. Depending on the effort it is possible to vary the length of the spike and the cylindrical reinforcement, which increases the mechanical load capacity.

So that the same safety element can be used in the large number of existing profiles precisely in the case of plastic profiles, seat parts are correspondingly provided in the sheet and / or in the frame, which on the side facing the counter-support, have some recesses already practiced destined to a drag in form of drag for the spike and for the cylindrical reinforcement.

In the space-saving configuration of the security element it is particularly advantageous that the security element is arranged hidden in the leaf and frame renewal. The hidden position is also possible thanks to the fact that the cable, in the supported position of the blade with respect to the frame, extends over the recess almost coincidentally in the longitudinal direction of the groove of the connecting rod fitting.

To save costs and simplify production, the counter-support is preferably made of a molded material under pressure.

Other advantageous configurations of the invention emerge from the drawings. They show:

- Figure 1, a security element in an individual representation,

- Figure 2, an exploded view of a security element according to Figure 1 with the respective details,

- Figure 3, a cross section of the beams of a leaf and of a window frame along the side of the window hinges, with a safety element,

- Figure 4, a cross-section of the beams of a leaf and of a window frame according to figure 3 in a rotational opening position and

- Figure 5, a representation of a counter-support with a cable in a front view and in a sectional representation of a side view.

With regard to the fundamental operation of the security element 1 and its cooperation with the window or door, we refer to document EP 1403457 B1, whose complete content is referred to in this regard. In figure 1 a safety element 1 is shown, which is composed of a cable 2 and two counter-supports 3, 4. In the exemplary embodiment shown, the counter-supports 3, 4 are configured as flat plates 21 which , for the adjustment of the assembly, they have a pin 5 and a cylindrical reinforcement 22 on the side oriented towards the sheet 15 or towards the frame 16, the cylindrical reinforcement 22 being crossed by means of fasteners not shown, for example fixing screws, in some holes 6 provided for this purpose. The counter-supports 3, 4 are identical and are pierced by the cable 2 in a cylindrical housing 7, which is arranged on the side opposite to the sheet 15 or the frame 16. In this context, the cylindrical housing 7 extends in the longitudinal direction of the counter-support 3, 4. At the same time, the cylindrical housing 7 is covered in its inner diameter so as to offer the cable 2 a guide 8 almost free of play.

The safety element 1 consisting of the cable 2 and the counter-supports 3, 4 comprises according to Figure 2 preferably an element 9, which is assigned at least to a counter-support 3, 4 on the side of the frame and on the side of the sheet, having at least one of the counter-supports 3, 4 a series of, at least one and advantageously two or more, counter-support steps 10 arranged one after the other in the direction of the cable 2 subjected to an active load and provided of controlled break points, on which the element 9 is supported. For this purpose, the counter-support steps 10 are arranged in the inner diameter of the cylindrical housing 7 and form ribs that face the free space. Depending on the embodiment, the ribs may take peripherally in each step the shape of a crown, which constitutes a counter-support step 10. To form a controlled breaking point, the fastening of the ribs to the inner diameter of the cylindrical housing 7 is configured with a material reduction, for example by narrowing. At the same time, the element 9 can be made of an elastic material, for example in a plastic material or in a metallic material that is coated with a plastic material or with a rubber material. However, it is also imaginable to manufacture the element 9 only in a metallic material.

By means of the counter-support steps 10 arranged one after the other at a certain distance according to figure 1, a braking of the leaf 15 is achieved and therefore a controlled reduction of the movement speed, in case of a failure of the hinge components not represented When a load is exerted on the element 9 and with sufficient kinetic energy, the counter-support steps 10 can be plastically deformed, so that, by means of the counter-support steps 10 arranged one after the other at a certain distance, a decrease is caused Gradual kinetic energy. At the same time, what can also be called the buffer section thus reduces the impact load impact.

If the safety element 1 is subjected to stress, a resistance is established by means of a support fixation, which according to figure 2 and figure 5 is produced through a thickening 13, 14 which is arranged in the

ends 11, 12 of the cable 2 and whose dimensions are adapted to the internal measurement of the cylindrical housing 7 arranged in the counter-support 3, 4, or of the guide 8, so that the greasing 13, 14 can move therein almost no game and has a stop edge that acts as a movement limiter.

If at each end 11, 12 of the cable 2 a thickening 13, 14 is placed, the cable 2 can be configured with specular symmetry. This simplifies on the one hand the assembly, which can be carried out without any risk of confusion, and on the other hand reduces the number of components and machines necessary for manufacturing.

In figure 1 it is shown that each end 11, 12 of the cable 2 is assigned a counter-support 3, 4 and that the counter-supports 3, 4 have an identical configuration, so that the entire safety element 1 has specular symmetry .

Figure 3 and Figure 4 show the sheet / frame arrangement 15, 16 in a sectional representation in which the pivot-tilt axis 17 is indicated, the stringers being configured as profiled bars. You can also use a sheet and a frame formed by a profile of wood or a light metal. The sheet 15 can be rotated in relation to the frame 16 around an axis 17. The axis 17 is formed by a hinge, not shown here, which is part of a window fitting. Other elements of the window fitting also act between the sheet 15 and the frame 16, which can be part of a connecting rod fitting that is arranged between the frame 16 and the sheet 15 and by which different axes 17. Figure 3 shows that the safety element 1 is mounted on the side of the axis of rotation between the blade 15 and the frame 16. It is provided that the safety element 1 does not currently have any function during normal operation of the hardware and that do not take action until a position outside of a nominal permissible position of sheet 15 in relation to frame 16 occurs.

The safety element 1 is configured so that, on the counter-support 3, 4, the cylindrical housing 7 is arranged on the side opposite to the sheet 15 or the frame 16. In this position, the cable 2 passes through the housing 7 In addition, in the housing 7, the counter-support steps 10 are visibly arranged. The visible side of the housing 7 enables easy assembly or disassembly of the cable 2 with respect to the counter-support 3, 4, without releasing the counter-supports 3 , 4 of the sheet 15 or of the frame 16. In addition, the counter-support 3, 4 is configured flat on the side facing the sheet 15 or towards the frame 16, which allows assembly without expensive processing, for example milling works on sheet 15 or frame 16.

So that the cable 2 can be accommodated, saving space and for easy mounting on the counter-support 3, 4, the cylindrical housing 7 extends, according to Figure 1, in the longitudinal direction of the counter-support 3, 4 with ends 18, 19 respectively open, the end 18 corresponding to the counter-support steps 10 for the introduction of the thickening 13, 14 of the cable 2 corresponding to the inner diameter of the cylindrical housing 7 and the end 19 adjacent to the counter-support steps being corresponding 10 in front of them, according to FIG. 2, a diameter-reducing opening 20, which is adapted to closely wrap the cable 2 and which, in case of loading, secures the thickening 13, 14 securing it. Thus, the cable 2 is fixed in the cylindrical housing 7 also in its inactive position.

In order to take advantage of the renewal 24 between the sheet 15 and the frame 16, according to figure 3, and to enable the assembly of the cable 2 from the freely accessible side of the counter-support 3, 4, it is also provided, according to the exploded perspective of the Figure 2, that the counter-support 3, 4 is composed of an essentially flat plate 21 and of the housing 7, extending in a longitudinal direction, along the entire length of the free side of the cylindrical housing 7 that is remote from the plate 21, from the end 18 to the end 19, a slit-shaped opening 26 that is adapted in width to the diameter of the cable 2 such that the cable 2 can be passed through it.

The detailed sectional representation according to figure 5 shows the safety element 1 with the plate 21, which, on the side facing the sheet 15 or the frame 16, has a pin 5 and, in the bore 6 provided to accommodate elements fasteners not shown, for example fastening screws, are provided with a cylindrical reinforcement 22. In this way, high starting resistance and simplified positioning of the safety element 1 are achieved. An interior gauge can also be conveniently used as an aid to the hole in order to fit the pin 5 and for the cylindrical reinforcement 22 in the sheet 15 and in the frame 16. Depending on the effort it is possible to vary the length of the pin 5 and the cylindrical reinforcement 22, which increases the capacity of mechanical load

So that the same safety element 1 can be used in the large number of existing profiles precisely in the case of plastic profiles, they are correspondingly provided in sheet 15 and / or in frame 16, as shown in Figure 2 and Figure 3, a seat piece 23 which, on the side facing the counter-support 3, 4, has recesses already practiced, not shown in the drawings, intended for a snap fit so that the pin 5 and for the cylindrical reinforcement 22.

It should also be noted that the configuration of the security element 1 results in a saving of space and, consequently, it is arranged hidden in the rebate 24 of the sheet 15 and of the frame 16. The hidden position is also made possible by the fact that the cable 2, in the supported position of the leaf 15 with respect to the frame 16, extends along the recess 24 almost coincidentally in the longitudinal direction of the groove 25 of the connecting rod fitting. Finally, we refer to the configuration of the counter-support 3, 4, which, thanks to the type of the component conceived according to Figure 1 and Figure 2, is very easy and therefore economical to manufacture when the counter-support is manufactured in a molding process under pressure. In this way the possible edges in the transitions that otherwise present a danger of material breakage can be selectively replaced by radii. This characteristic has a positive impact in particular as regards the forces that can be expected to appear in the event of a load of the safety element 1.
