Likewise, according to another embodiment of the invention, it can be provided that the second traction means is a second ball cord with at least one ball. The length of the second traction element between the energy storage element and the second receiving element can be easily adjusted by the several spaced balls. This adjustability can be used to adjust the force with which the guard is operated. Thus, by shortening the length of the traction mechanism, the force can be increased by greater pretensioning of the force storage element, and by lengthening the length of the traction mechanism, the force can be increased by less pretensioning of the force storage element.

cher elements can be reduced.

According to a further embodiment of the invention it can be provided that the force storage element is a spiral spring, whereby the force storage element saves space and is protected from environmental influences in a profile element of the casement or a mounting profile, in particular a mounting

several interconnected casement profiles 4 may be formed.

According to one embodiment variant, the protective device 1 can have a mounting frame 5 . The mounting frame 5 can be used to attach the protective device 1 . However, the protective device 1 can also be fastened (attached) directly in the building opening, for example on the window or on the door or on the wall. Furthermore, according to another embodiment variant, provision can be made for the protective device 1 to have only one mounting profile 6 or mounting element. However, the mounting profile 6 or mounting element can also be part of the mounting frame 5 . The mounting frame 5 can also have several frame profiles (mounting profiles 6) which are connected to one another.

Casement 2 be connected.

The protective device 1 has at least one hinge 7 . Two hinges 7 or more than two hinges, for example three or four, are preferably provided. The protective device 1 can be rotated or pivoted (on the respective further element, as explained above, for example the mounting frame 5 or the mounting profile 6 or a door or window frame or the embrasure, etc.) by means of the hinges 7 , i.e. as a rotary or swivel element, for example as a revolving door. The two hinges 7

are preferably arranged on a vertical casement profile 4.

The at least one hinge 7 (preferably all hinges 7 are of the same design) has an upper hinge part and a lower hinge part, which can be pivoted or rotated in relation to one another. For this purpose, the upper hinge part has a first pivot axis receptacle and the lower hinge part has a second pivot axis receptacle.

Fig. 2 shows a section of the protective device 1. Shown is part of the upper casement profile 4 and a locking device 8. The locking device 8 is used to ensure that the casement 2 (i.e. the wing of the protective device 1, for example the door leaf) after the Open again automatically

returns to the closed position.

The locking device 8 comprises an energy storage element 9. The energy storage element 9 is designed as a tension spring, in particular as a spiral spring, in the embodiment variant of the locking device 8 shown. However, the energy storage element 9 can also be designed differently, for example as a gas pressure spring, etc. In this embodiment variant of the energy storage device, the energy storage element 9 is preferably completely in the casement 2, i.e. one of the casement profiles 4 (i.e. a hollow chamber of the casement profile 4), preferably

a vertical casement profile 4 arranged.

By way of explanation, it should be mentioned that the force storage element 9 is used to store at least part of the force or energy that is necessary for opening the casement 2 . This stored force or energy is then used for the automatic closing movement, for which, for example, the tension spring moves from a tensioned position (open position of the casement 2) to a rest position

(Closed position of the casement 2) returns.

The energy storage element 9 is arranged between a first receiving element 10 and a second receiving element 11 (visible from FIG. 1). The first receiving element 10 can be connected to the protective device 1, in particular a casement profile 4, preferably a vertical casement profile 4, in particular the casement profile 4, in which the energy storage element 9 can be connected

or is arranged. The second receiving element 11 is with the building $Öff-

tion having wall or arranged on this wall mounting element, in particular a mounting frame profile 6 (see Fig. 1), preferably a horizontal mounting frame profile 6, especially on the upper horizontal

Mounting frame profile 6, arranged or connectable.

It should be mentioned at this point that the embodiment of the protective device 1 with the force storage element 9 in the casement 2 described here is the preferred one, since in this case the force storage element is automatically removed when the casement 2 is dismantled. With a corresponding design of the force storage element 9, for example as a gas pressure spring, and the connections to the casement 2 and the mounting frame 5, the design described here can also be reversed. In this case, instead of the casement frame 2, the mounting frame 6 is used in this description, and instead

of the mounting frame 6 of the sash frame 2 to read.

The energy storage element 9 is connected to the first receiving element 10 with a first traction means 12 and/or to the second receiving element 11 with a second traction means 13 . In this case, the expression "and/or" refers to the fact that the energy storage element 9 can also be connected directly to the first receiving element 10 or the second receiving element 11, i.e. without traction means 12, 13. However, this embodiment is not the preferred one

Within the meaning of the invention, tool-free means that no tool is required to release the connection between the first traction means 12 and the first receiving element 10 and/or to release the connection between the second traction means 12 and the second receiving element 11, this connection(s). ) So only by hand and without destroying the first traction device 12 and the first receiving element 10 and/or the second traction device 13 and the second receiving

meelement 11 can (can) be solved.

N2021/23400-AT-00

In the preferred embodiment variant of the locking device 8, the first traction means 12 is a first ball cord with at least one ball 14. The ball 14 is used to connect the first traction means 12 to the first receiving element 10. For this purpose, it has an undercut ball receptacle 15, as can be seen in Fig 3, which shows a preferred variant embodiment of the first receiving element 10. FIG. The undercut ball receptacle 15 can be provided with a slit 16 and can be embodied as a slit in its entirety in the longitudinal direction or that widens in the longitudinal direction. You can also with insertion bevels 17 at the open end of the slot 16 for easier insertion of the ball cord

be trained.

The width of the slot 16 of the ball socket 15 is at least as large as the diameter of the cord of the ball cord. In addition, the slot 16 or the slot 16 that widens in the longitudinal direction is nowhere as wide as the diameter of the ball 14, so that the ball 14 is prevented from sliding out by the undercut. The area of the first receiving element 10 adjoining the undercut is dimensioned in such a way that the ball 14 can be accommodated therein.

It should be mentioned at this point that instead of a ball 14, other shaped bodies can also be arranged on the first traction means, for example cylinders, cubes, etc. The functionality of these shaped bodies is also tool-free

Dismantling possible as with the ball 14.

In the embodiment variant shown, tool-free disassembly is achieved in such a way that by tightening the first traction means 12, the force that acts on the ball 14 through the energy storage element 9 is reduced, so that the ball 14 is subsequently pushed out of the ball receptacle 15 -

In the preferred embodiment variant of the locking device 8, this tool-free disassembly does not necessarily serve to disassemble the wing frame.

mens 2 with the locking device 8, but preferably the setting of the

N2021/23400-AT-00

tension of the energy storage element 9. For this purpose, the first traction means 12 has a plurality of balls 15 (or shaped bodies) spaced apart from one another, so that the length of the first traction means 12 between the energy storage element 9 and the first receiving element 10 can be changed. If the first traction means 12 is hooked into the first receiving element 10 with a ball 14, which is arranged closer to the energy storage element 9 compared to other balls 15, this is pretensioned more, which also increases the force with which the locking device 8 automatically closes the casement frame 2 becomes. Conversely, with a corresponding

With the ball 14 further away, this force can be reduced.

The plurality of balls 15 (or shaped bodies) are preferably arranged at the same distance from one another. However, it can also be provided that this distance becomes smaller or larger in order to exert a corresponding influence on the prestressing of the energy storage element 9 . For example, by reducing the distance between the balls 15 in the direction of the power storage element

ment 9 the preload force can be adjusted more precisely.

In the embodiment variant of the first receiving element 10 shown in Fig. 3, it is provided that the first traction means 12 is arranged within the corresponding casement profile 4 (in particular in a hollow chamber of the casement profile 4) and via an opening in the region of the first receiving element 10 from the casement profile 4 exits so that it can be operated without tools in the sense of the above statements. The first receiving element 10 can also have an opening behind the ball socket 15, through which the first traction means 12 can be guided out of the casement profile 4 via the undercut ball socket 15 to the outside. In this way, the first traction means 12 can be arranged to run within the casement frame 2 so as to be largely protected from environmental influences, with the exception of the protruding end. As can be seen from the screw shown in FIG. 3, a surface 18 of the first receiving element 10 penetrated by this screw is its

visible side.

N2021/23400-AT-00

According to a non-preferred embodiment of the protective device 1, however, it can also be provided that the first traction means 12 is on the outside of the wing

frame 2 runs, for example in an outwardly open groove.

The first traction device 12 can be directly connected to the energy storage element 9 . For example, the first traction means 12 may have a loop with which

it is hung on the force storage element 9.

In the preferred embodiment variant of the locking device 8 , however, the first traction means 12 is connected to the energy storage element 9 via a connecting element 19 . A variant embodiment of the connecting element 19 is shown in FIG. This can have an approximately H-shaped form, with a web 20 being arranged in one part, which connects the two H-legs to one another and in which a recess or an opening 21 is formed, into which the energy storage element 9 can engage, for example an end

can be attached to the tension spring.

A receptacle 22 for a ball 14 (see FIG. 2) or a shaped body of the first traction means 12 can be provided in the adjoining part of the connecting element 19 . This connection between the first traction mechanism 12 and the connecting element 19 can be non-positive and/or positive and/or material

be made conclusive.

In the preferred embodiment variant of the locking device 8, the second traction means 13 is designed as a second ball cord with at least one ball 14 (see FIG. 2) or at least one shaped body. This ball 14 is arranged in the end region, in particular at the end, of the second traction means 13 and serves for the tool-free, detachable connection to the second receiving element 11, and there

with the mounting element, for example the mounting frame 5 (see Fig.

1).

A variant embodiment of the second receiving element 11 is shown in FIG. This is a U-shaped bracket with two fastening straps in the end

rich trained. In the middle part of the bracket there is a slot-shaped

N2021/23400-AT-00

Breakthrough 23 arranged. This has an expanding end area 24 . A depth 25 between the central part and the fastening tabs is dimensioned in such a way that the ball 14 or the shaped body can be accommodated between the second receiving element 11 and the component to which it is fastened, for example the mounting element or the mounting frame 5, after which the second traction means 13, ie in particular the cord of the ball cord, was introduced into the opening 23. The tool-free release of the connection between the second traction means 13 and the second receiving element 11 is thus also easy to implement. By pulling the second pulling means 13 out of the engagement area of the second receiving element 11, the locking device 8 can be easily deactivated at any time if required and vice versa activated again. This makes it possible to leave the sash 2 in the open position at any time, if necessary, with a flick of the wrist by locking the locking device 8 as described

is deactivated.

Of course, the second receiving element 11 can also be designed differently, as long as the tool-free solution of the connection between the second

Traction means 13 and the second receiving element 11 is achieved.

The second traction means 13 can be connected to the energy storage element 9 in the same way as the first traction means 12, in particular also via a connecting element 19 (see FIGS. 2 and 4). The above explanations can therefore also be transferred accordingly for this connection. In the case of the arrangement of the connecting element 19, the second traction means 13 can have a second ball 14 or a second shaped body, in order to use this to establish the connection to the connecting element as described above.

ment 19 to produce.

As can be seen from FIG. 1, the second receiving element 11 can be arranged in the area of the upper horizontal mounting element or mounting profile 6 . If the energy storage element 9 is arranged in/on a vertical profile, a deflection of the second traction means 13 is necessary. For this purpose, it can be provided according to one embodiment that the first traction means

has at least one 90° deflection in the longitudinal direction. This can be done via a

N2021/23400-AT-00

Deflection element 26 can be provided, which is shown in FIG. 6 and can also be seen in FIG. If the second traction device 13 is partially arranged in a casement profile 4 , the deflection element 26 can have an opening 27 through which the second traction device 13 emerges from the casement profile 4 . This opening 27 can be provided with a bevel 28 running in the direction of the deflection, in order to support the deflection of the second traction means 13 or to be able to make it easier. If necessary, the side wall delimiting the opening 28 and/or the bevel 28 can have a friction-reducing coating, for example made of polytetrafluoro

rethylene, be provided.

Next, the deflection element 26 may have a guide element 29 with which

the second traction means 13 is at least partially guided on the upper casement profile 4 of the casement 2. The guide element 29 can, for example, be an angle element, as is shown in FIGS. But it can also

be designed differently, for example as an eyelet, etc.

The second traction means 13 can also have a further 90° deflection, which can be supported or implemented, for example, with a further deflection element 30 . The other deflection element 30 can be seen in FIGS. This further deflection essentially takes place in a direction perpendicular to the preceding 90° deflection. The further deflection element 30 can have a deflection roller 31 in order to support the deflection of the second traction means 13 when moving the casement 2 from the closed position to the open position and vice versa or to reduce the wear on the second traction means 13 . Instead of a deflection roller 31, it is also possible to have only one fixed deflection, for example a deflection cylinder, a deflection

hyperboloid, etc.

If necessary, the surfaces coming into contact with the second traction means 13 can be provided with a friction-reducing coating, for example made of polymer

Iytetrafluoroethylene, be provided.

N2021/23400-AT-00

To improve the arrangement of the second traction means 13 in a casement profile 4, it can be provided that a corner bracket 32 shown in Fig. 8 is provided with an opening 33, in particular a bore, through at least one of the two legs 34 of the corner bracket 34, through which the second traction means 13 is guided. Such corner brackets 34 can be used to connect the wings

gel frame profiles 4 are used, as can be seen from FIG.

But it is also possible that the corner angle 31 with a guide provided on the outside of a leg 34, for example a guide groove, for the second

Traction means 13 is equipped.

In Fig. 9 an embodiment of the locking device 8 is shown. In this case, the energy storage element 9 can be detached from the mounting element, for example the mounting frame 5 shown in FIG. 1, without tools. For this purpose, the locking device 8 can have a pivoting locking element 35 which is arranged on the mounting element. The pivot locking element 35 also allows the energy storage element 9 to be adjusted between an operative position and a non-operative position by engaging or disengaging the pivot locking element 35 with the energy storage element 9 . For the engagement of the swivel locking element 35, this can have, for example, an angled end area which fits into a corresponding recess on the power storage unit.

cher element 9 can be brought.

The energy storage element 9 itself can be designed, for example, as a torsion spring

be formed.

A rotatable force setting element 36 which is connected to the force setting element 9 can be provided for the adjustment or setting of the force with which the casement 2 is brought back into the closed position after opening. The force setting element 36 can, for example, be designed at least partially in the form of a mandrel. The twisting of the force adjustment element 36 causes the force storage element to be prestressed, depending on the direction of rotation

9 reduced or enlarged.

N2021/23400-AT-00

In order to fix the position of the force setting element 36 in a definable position, the force setting element 36 can be connected to a pivoting lever 37 according to one embodiment variant, which is arranged so that it engages in a recess 38 in the force setting element 9 or a receptacle for the force storage element 9 in a detachable manner. For this purpose, the pivoting lever 37 can, for example, be equipped with an angled

kelten end be formed.

According to a further embodiment of this locking device 8 can be provided that the force storage element 9 with a connecting pin 40 with

is detachably connected to the respective mounting element without tools.

Although the energy storage element 9 has always been described above as being arranged in a vertical casement profile 4 or assembly profile 6, within the scope of the invention there is also the possibility of arranging the energy storage element 9 in a

to be arranged with a horizontal casement profile 4 or mounting profile 6.

The exemplary embodiments show possible variants of the protective device 1 or the closing device 8, it being noted at this point that combinations of the individual variant variants are also possible

are.

Finally, for the sake of order, it should be pointed out that for a better understanding of the structure of the protective device 1 or the closing device 8

these are not necessarily shown to scale.
