The invention further relates to a window or door, in particular tiltable, having a fixed frame and such a spreading device (20), wherein the spreading device (20) is preferably arranged on the upper side of the door leaf. Finally, the invention preferably relates to a method for mounting or demounting such a window or such a door, wherein the upper side of the sash or leaf is pivoted away from or towards the fixed frame in order to move the first pin (26) into and out of the slot-like opening area (40).

Description

Deployable devices mountable by various means

Technical Field

The invention relates to a spreading device for connecting a fixed frame of a window or door to a leaf of the window or door. The deployment device has a cuff rail assembly that can be fastened to the fan and has a cuff rail and a deployment arm for connecting the cuff rail to the fastening frame.

The invention also relates to a window or door with such a deployment device. Finally, the invention relates to a method for installing a window or door.

Background

It is known to connect the leaves of a window or door to the fixed frame of the window or door by means of a spreading device. In particular, a tiltable fan, preferably a fan that can be swiveled open and tilted ("swivel-tilt fan"), is connected to the stationary frame by means of a spreading device.

A deployment device of this type is already known, for example, from EP 1 612 354 A2. EP 1 612 354 A2 discloses a tiltable fan on which guide elements are arranged. A fan is connected to the fixed frame by a spreading device. The auxiliary rod of the deployment device can be arranged on the guide element with a snap connection.

DE 85 25 718 U1 describes a detachable hinge connection between two fittings of a window, door or the like. The hinged connection includes a perforated leaf spring on the first fitting that is engaged behind by a mushroom head pin of the second fitting.

DE 40 233 A1 discloses connecting the deployment device to a pendulum bearing. The deployment device is connected in the direction of the bearing axis. The mounting position between the pivot bearing and the fastening leg of the deployment device is fixed by a yieldable locking element that springs in the mounting direction.

DE 91 02 070 U1 discloses a device for releasably connecting a deployment arm to an auxiliary lever. The auxiliary lever has a locking claw which can be pivoted or bent open by means of a bearing pin of the spreading arm. In the installation position, the locking claw engages behind the bearing pin. An arcuate actuating mechanism is provided on the auxiliary lever. The locking claw can be opened by pressing the operating mechanism so as to detach the auxiliary lever.

EP 0 495 234 A1 discloses connecting the deployment arm to the slider. The spreading arm has a mushroom pin which is acted upon from behind by a spring element in the mounted state. An opening is provided in the slider in order to press the spring element with a tool and thereby release the connection.

GB 2 253 007A discloses a deployment arm for a window or door which may be connected to a fixed frame or leaf by a rocker connection. The turn bar has an elongated bar with a widened flange. The elongate bar element can only be moved into or out of the open slot of the turn bar connection part when the window or door is in the closed state.

DE 30 17 483 A1 discloses a suspendable spreading device for windows, doors or the like. In this case, a guide section with a longitudinal slot is provided on a window, door or similar leaf, which can be guided into the widened opening. The stent has a mushroom pin, the head of which can be inserted into the opening. The mushroom pin can then be pushed into the longitudinal groove. In order to prevent the mushroom pin from accidentally coming out of the opening, a blocking element is provided, which can be mounted in the region of the opening, so that the opening is closed in the mounted state of the spreading device.

An unfolding device for a tiltable fan is known from EP 0 128 371 A2. The deployment device has a deployment arm which is connected at its fan-side end to the slider by a pin-hole connection. A rotatable securing element, which is arranged on the slider, engages the spreading arm end in its securing position. Furthermore, EP 0 128 371 A2 discloses a push-pull mechanism which is connected to the frame side by means of a bayonet connection.

However, known deployment devices are often either not intuitive or cannot be quickly installed or removed. In particular, the deployment device is often installed by skilled window installers who wish to have a quick installation, but is removed by unskilled installers who prefer a more intuitive fastening.

Disclosure of Invention

It is therefore the task of the present invention to provide a deployment device that is intuitive and easy to install and remove quickly. The invention also provides a window or door with such a deployment device and a method for installing a window or door.

According to the invention, this object is achieved by a deployment device according to claim 1, a window or door according to claim 14 and a method according to claim 15. The dependent claims reflect preferred embodiments.

The object of the invention is therefore achieved in a surprising manner simply by the deployment device described at the outset, in which the deployment arm can be reversibly releasably connected to the cuff-rail assembly in at least two, in particular exactly two, different connection modes.

Hereby, it is possible to provide a connection which enables a very quick connection of the fan directly or indirectly to the fixing frame, while at the same time providing a further connection which also allows easy handling by unskilled handling personnel. Thus, the accessory of the present invention can address different target groups.

It is further preferred that the deployment arm can be released from the cuff track assembly by at least two, in particular exactly two, different removal means.

Preferably, the deployment arm can be connected to the cuff track assembly in at least two, and particularly exactly two, ways without the use of tools.

It is further preferred that the deployment arm can be released from the cuff track assembly without tools in at least two, in particular exactly two, disassembly modes.

The cuff track assembly is preferably engaged posteriorly by the deployment arm in sections in the mounted state of the deployment device. In order to provide such a rear fit, the deployment arm in the first connection mode is preferably pushed onto the cuff rail assembly in sections so as to act on the cuff rail assembly in sections from behind. In the second connection, a part of the deployment device is preferably designed to be pivotable, so that there is a rear fit in the non-deflected state and no rear fit in the deflected state.

The spreading device can have a first pin, which has at least one projection at one end for acting from behind on at least one side, preferably both sides, of the slotted opening region of the first opening. In order to realize the first connection, the first opening also has in this case a widened opening region into which the first pin can be inserted and from which the first pin can be pushed into the slot-like opening region. In order to realize the second connection, the first pin is in this case relatively deflectable to the slot-like opening region, in particular about the longitudinal axis of the first pin. The first pin is preferably designed at least at its free end in a rotationally asymmetrical manner with respect to its longitudinal axis, so that it does not act behind on the slot-like opening area in the deflected position and does not act behind on the slot-like opening area in the undeflected position.

In other words, the first pin can form a bayonet lock with the slot-like opening region to achieve the second connection. In order to realize the first connection mode, the first pin can be pushed in and out through the widened opening area which is connected with the slot-shaped opening area.

The widened opening area is designed to be sufficiently large to allow the first pin to be inserted into the widened opening area in the non-deflected position. To this end, the width of the widened opening area corresponds at least to the maximum width of the free end of the first pin in the non-deflected position.

The width of the slot-like opening area (in particular in the slot-like opening area directly adjacent to the widened opening area) exceeds at least in sections the maximum width of the free end of the first pin in the deflected position, but is at least in sections below the maximum width of the free end of the first pin in the undeflected position.

The width is preferably determined perpendicular to the longitudinal axis of the first pin, in particular perpendicular to the longitudinal axis of the cuff rail.

Preferably, the first pin is arranged or formed on the deployment arm and the first opening is arranged or formed on the cuff track assembly. Thereby making the deployment device particularly easy to handle.

It is further preferred that the relative pivotability of the first pin to the first opening, in particular to the slot-like opening area, is achieved by: the pin may be deflectable about its longitudinal axis. The deployment device can thereby be realized in a particularly structurally simple manner.

In other words, the following embodiments are preferable: in this embodiment, the deployment arm has a first pin that widens at its free end, and the cuff track assembly has a first opening with a widened opening area and a slot-like opening area,

wherein, in order to realize the first connection mode, the widened end of the first pin can be inserted into the widened opening area, and the first pin can move into the slot-shaped opening area, in the opening area, the first pin acts on the side of the slot-shaped opening area from the back; and

in order to realize the second connection, the first pin can be pivoted about its axis, and the widened end of the first pin is formed rotationally asymmetrically with respect to the longitudinal axis of the first pin, so that it does not act behind on the side of the slot-shaped region in the first pivoted position (deflected position) and acts behind on the side of the slot-shaped region in the second pivoted position (undeflected position), in which it can be inserted into the widened opening region.

In order to further simplify the design, the first opening, in particular the widened opening area and the adjoining slot-like opening area, can be configured as a keyhole.

The first pin is preferably T-shaped at its free end in order to simplify its production and to reliably act from behind on the edge of the slot-shaped region.

The maximum width of the free end of the first pin in the deflected position of the first pin may correspond to the diameter of the first pin in the region near the free end of the first pin.

The first pin can be designed in the form of a mushroom-head pin, the head width of which is reduced at least on one side, in particular on both sides.

To facilitate the deflection of the pin, the spreading device may comprise a lever which is connected at one end in a torsionally fixed manner to the first pin.

The lever may have an overtorque protection to limit the pivotability of the lever relative to the deployment arm to less than 180 °, in particular less than 150 °, preferably less than 100 °. This makes mounting and dismounting more intuitive. The overtwist protection can have a projection which, in the pivoted position of the lever, stops against the deployment arm and thus limits the maximum pivotability. The projection may be configured in the form of a chamfer of the lever.

The first opening can have a widened opening region at one end and a narrowed neck region at the other end in the axial direction, at least one side, in particular both sides, of which can be pressed elastically, i.e. resiliently, in order to make possible a locking of the first pin behind this neck region (from the widened opening region). Thereby, an additional safety device can be realized, by means of which the fan can be detachably held in the tilted position.

The term "axial" is to be understood in the sense of the present invention as "longitudinal direction of the deployment arm mounted on the cuff track in a position parallel to the cuff track". Furthermore, in the sense of the present invention, the terms "upper", "lower", etc. should be considered to refer to the installation state of the window or door.

Preferably, the cuff rail assembly includes a connection member fixed to the cuff rail, and the first opening is formed in the connection member. By replacing the connecting member, different opening characteristics of the fan can be achieved. In particular, the angular width of the fan can be determined by the axial length of the slot-shaped opening region. The connecting part is preferably integrally formed, i.e. one-piece.

It is particularly preferred that the connecting part is arranged axially displaceably on the cuff track, wherein the connecting part can be secured in different axial positions on the cuff track by means of a locking device, in particular can be locked by means of locking teeth. Thereby, the tilt width of the fan can be adjusted with the fan suspended.

In a particularly preferred embodiment of the invention, the deployment device has a stop device which, after being moved in the first connection, axially fixes the deployment arm to the cuff-rail assembly. The stop device is preferably reversibly releasable here.

It is further preferred that the deployment device comprises an auxiliary rod assembly with an auxiliary rod. In this case, the deployment arm is part of a deployment scissors composed of a deployment arm and an auxiliary rod.

The auxiliary lever assembly may swing and may have a second opening for receiving a second pin of the limiting device.

The auxiliary rod assembly may include a spring element. The spring element is preferably designed in the form of a leaf spring.

The spring element may have, at least in sections, a stop for the second pin.

The spring element may comprise a portion of the second opening. A portion of the second opening may form the stop for the second pin.

The auxiliary lever may have a recess (in particular on the end face) for abutment with the second pin in the locking position. The recess may form part of the second opening.

It is particularly preferred that the spring element can be pressed at least in sections (in particular against the cuff track) so that the second pin can be axially removed from the second opening.

The second pin is preferably arranged or formed on the first deploy arm and the auxiliary rod assembly is preferably arranged or formed on the cuff track.

The first pin and/or the second pin may have any cross section. However, it is preferred that the first pin and/or the second pin have a mainly circular cross section in its longitudinal extension.

The object of the invention is also achieved by a window or door with a spreading device for connecting a fastening frame to a door leaf of the window or door.

The window or door preferably has a tiltable leaf. The cuff track assembly is then preferably arranged on the upper stay of the fan. The deployment arm is connected to the fixed frame, in particular by an upper corner support. The deployment arm may be referred to as an "axe arm" and the cuff track may be referred to as an "axe cuff".

Finally, the object according to the invention is achieved by a method for mounting a deployment device, in particular the one described above, having the following method steps:

a) Attaching the deployment arm to the fixed frame and securing the cuff track assembly to the fan;

b) Inserting a first pin of the deployment arm into the widened open area of the first opening of the cuff track assembly;

c) The fan is moved axially so that the first pin is inserted into the slot-like opening region of the first opening, in which region it acts with its widened free end at least in sections from behind on the edge of the slot-like opening region, wherein the axial movement of the fan is continued until the stop device is locked.

In method step a), the cuff-rail assembly is preferably fixed to the upper stay of the fan. The connection of the deployment arm to the fixed frame is preferably achieved by an upper corner support.

In method step B), the upper side of the fan is preferably deflected toward the fixed frame in order to insert the first pin into the widened opening region. Here, the fan may be supported at the lower corner. In particular, the fan may be supported at the lower corners by lower corner mounts on the fixed frame.

The insertion of the first pin in method step B) is preferably carried out with the upper side of the fan deflected toward the fixed frame.

The movement of the fan in method step C) is preferably carried out by deflecting the upper side of the fan away from the fixed frame.

Method steps a), B) and/or C) are preferably carried out with the fan rotated open, wherein the fan is arranged on the fixing frame, in particular by means of the lower corner support.

The deployment device, the window or the door used in carrying out the method of the invention may have the features described above and/or below.

Further advantages of the invention can be derived from the description and the drawings. Likewise, the features mentioned above and those yet to be described in detail can also be used in accordance with the invention either individually or in any combination. The embodiments shown and described are not to be understood as exhaustive enumeration but rather have exemplary character for the description of the invention.

Detailed Description

Fig. 1 shows the upper part of a window 10 with a fixed frame 12 and a sash 14 arranged on the fixed frame 12. The fan 14 has an upper brace 16. Between the upper supporting bar 16 and the upper corner support 18, there are provided unfolding means 20 for holding the fan 14 tiltably and/or rotatably open on the fixed frame 12.

Fig. 2 shows a deployment device 20. The deployment device has a deployment arm 22 that is connected to the fixed frame 12 (see fig. 1) by an upper corner bracket 18 (see fig. 1). A cuff rail assembly 24 (see fig. 1) is provided on the upper strut 16, particularly on a fitting portion channel (not shown) of the upper strut 16 (see fig. 1). The suspension of the fan 14 (see fig. 1) is accomplished by the connection of the deploy arms 22 to the cuff track assembly 24.

The deployment arm 22 has a first pin 26, the free end 28 of which widens T-shaped. Furthermore, the deployment arm 22 has a second pin 30. The cuff rail assembly 24 has a cuff rail 32. A connecting member 34 is provided on the cuff rail 32. The connecting part 34 has a first opening 36 for receiving the first pin 26. The first opening 36 has a widened opening area 38 for inserting the first pin 26 and a joint slot-like opening area 40 with

flanks

42, 44. The first pin 26 is designed to hook behind the

flanks

42, 44 with its T-shaped widened end 28 in the mounted state of the stent 20.

In the slot-like opening area 40, there is a neck area 46. The neck region 46 narrows and thus makes it difficult for the first pin 26 to pass through when the first pin 26 moves from an inclined position 48 in which the fan 14[ see fig. 1] is in an inclined position in the longitudinal direction of the cuff track 32. Thereby, impact protection of the deployment device 20 in the tilted position 48 is achieved.

An accessory bar assembly 50 is provided on the cuff track 32. The auxiliary rod assembly 50 can be deflected away from the position shown in fig. 2 (parallel to the longitudinal axis of the cuff track 32) by a swing bearing 52. The auxiliary lever assembly 50 has an auxiliary lever 54 which, in the mounted state of the spreading device 20, forms a spreading shear with the spreading arm 22.

Furthermore, the auxiliary rod assembly 50 comprises a spring element 56. A second opening 58 is formed in the spring element 56 for receiving the second pin 30. In the mounted position of the spreading device 20, the second pin 30 continues to rest on the groove 60 of the auxiliary lever 54. The recess 60 here forms part of the second opening 58. The groove 60 is preferably at least in sections of semicircular configuration.

In order to facilitate the entry of the second pin 30 into the second opening 58 in the axial movement, the spring element 56 has a ramp 62 at its free end. When the second pin 30 enters the second opening 58, the spring element 56 is pressed in the direction of the cuff track 32. Once the second pin 30 enters the second opening 58, the spring element 56 rebounds and axially locks the second pin 30. Thus, the auxiliary rod assembly 50 forms the limiting means 64 together with the second pin 30.

The deployment device 20 is intended to provide a simple and quick possibility for various users to mount or dismount the fan 14 (see fig. 1) on the fixed frame 12 (see fig. 1). To this end, the deployment arm 22 can be mounted on or removed from the cuff track assembly 24 in at least two different ways, particularly exactly two ways.

A first connection of the mounting of the deployment arm 22 to the cuff track assembly 24 is shown in figures 3a to 5 b.

Figure 3a shows the deployment device 20 with the cuff rail assembly 24 mounted to the sash 14 and the deployment arm 22 mounted to the upper corner mount 18 (see figure 1). The first pin 26 is at the same level in the axial direction as the widened opening region 38, so that the first pin 26 can be introduced into the widened opening region 38 in the direction of its longitudinal axis L26 in a next mounting step. To this end, the width B38 of the widened opening region 38 corresponds at least to the maximum width B28-1 of the free end 28 of the first pin 26 in the illustrated non-deflected position. The widths B28-1 and B38 are determined perpendicular to the longitudinal axis L26 of the first pin 26 and perpendicular to the longitudinal axis of the cuff rail 32.

Fig. 3b shows how an axial correspondence of the first pin 26 (see fig. 3 a) with the widened opening area 38 (see fig. 3 a) is achieved. According to fig. 3b, the fan 14 is raised on its free side in the rotated open position. Here, the fan 14 is preferably connected to the fixed frame 12 at a lower corner support 66. If the fan 14 is fixed to the lower corner support 66, the swinging movement shown in fig. 3b is automatically performed by the lifting of said fan 14.

Fig. 4 shows a next mounting step, in which the first pin 26 is sunk into the widened opening region 38. Here, this sinking has already occurred due to the lifting of the fan 14 (see fig. 3 b).

Fig. 4 further shows that the second pin 30 presses the spring element 56, in particular in the region of its ramp 62. Thereby, the spring element 56 is tensioned.

Fig. 5a shows a next mounting step, in which the first pin 26 is moved into the slot-like opening area 40 so as to act with its widened free end 28 (see fig. 2) from behind on the flanks 42, 44 (see fig. 2) of the slot-like opening area 40. Thus, the deployment arm 22 is locked to the cuff track assembly 24 in the direction of the longitudinal axis L26 of the first pin 26.

Further, axial displacement of the deploy arms 22 causes the second pins 30 (see also fig. 2) to sink into the second openings 58 (see fig. 2). The spring member 56 is released and secures the deployment arm 22 against axial movement relative to the cuff track assembly 24. Thus, the deployment arm 22 is secured against removal relative to the cuff track assembly 24 in all three spatial directions.

Fig. 5b shows that the movement of the first pin 26 (see fig. 5 a) into the slot-like opening area 40 (see fig. 5 a) is done by swinging the upper side of the fan 14 away from the fixed frame 12. If fan 14 is secured to lower corner mount 66, this movement occurs automatically as fan 14 is lowered. In other words, the deployment arm 22 (see fig. 5 a) is locked to the cuff track assembly 24 (see fig. 5 a) by yielding to the weight of the fan 14 itself, so that it can move slightly downward on the free side.

Fig. 6 to 8 show a first disassembly of the stent 20.

Fig. 6 shows a first disassembly step in which the spring element 56 is pressed by a tool 68, here in the form of a screwdriver, to allow the second pin 30 to move axially. Alternatively, the pressing can also be performed with the fingers without tools. The compression is preferably performed towards the cuff track 32.

Fig. 7a illustrates the next axial displacement of the deployment arm 22 relative to the cuff track assembly 24. As a result, the first pin 26 no longer acts from behind on the slot-like opening area 40 (see also fig. 2). The position of the window 10 in fig. 7a corresponds to the position in fig. 4.

Fig. 7b shows that for this axial displacement the upper side of the fan 14 is swung towards the fixed frame 12.

Fig. 8 shows how the deployment arm 22 is finally extracted upwards. Here, the first pin 26 is pulled out of the widened opening region 38. The position of the window 10 in fig. 8 corresponds to the position in fig. 3 a.

The first mounting and dismounting manner is particularly advantageous for experienced window workers, since it can be carried out quickly and also here particularly safely. By retracting the first pin 26 (see fig. 5 a) into the slot-like opening area 40 (see fig. 5 a), an unintentional lowering of the fan 14 (see fig. 5 b) can be caught.

Fig. 9 to 11 show a second mounting or dismounting manner of the stent 20. This second manner of mounting or dismounting is very intuitive and is therefore particularly suitable for unskilled installers.

Fig. 9 shows that the first pin 26 is connected to the lever 70 in a rotationally fixed manner. By toggling the lever 70, the first pin 26 is toggled in a first disassembly step to a toggled, unlocked position.

The lever 70 has an overtorque protection 71 (see in particular fig. 8), here in the form of a chamfer.

Fig. 10 illustrates a further step of disassembly in which the deployment arm 22, along with the first pin 26, is lifted from the cuff track assembly 24. As a result of the first pin 26 being pivoted, the widened free end 28 of the first pin 26 no longer engages behind the edge of the slot-like opening area 40, so that the first pin 26 can be displaced in the direction of its longitudinal axis L26. The width B40 of the slot-like opening region 40 is here at least in sections greater than the maximum width B28-2 of the free end 28 of the first pin 26 in the deflected position, but less than the maximum width B28-1 of the free end 28 of the first pin 26 in the undeflected position (see fig. 3 a).

As a result, the first pin 26 can be pulled out of the slotted opening region 40 in the pivoted position by pivoting the lever 70 in order to detach the deployment arm 22. In the pivoted position, the first bolt 26 can, in turn, be inserted into the slot-like opening region 40 and then pivoted in order to mount the first deployment arm 22.

In the mounted state of the spreading arm 22, the first pin 26 is moved in the slot-like opening area 40 in order to pass from the closed position of the leaf 14 (see fig. 1; but where the leaf 14 is shown rotated to the open position) into the tilted position. The maximum tilting width can be achieved by an axial displacement of the connecting part 34. In order to be able to lock the connecting part 34 in different axial positions, the latter has a locking device 72.

The first pin 26 may be riveted to the lever 70. The lever 70 may include a spring section 74 to create a defined pressure of the lever 70 against the deployment arm 22. The spring section 74 may be pressed during riveting.

The lever 70 may include (particularly at its free end) a lever projection 76 (preferably in the form of a chamfer of the lever 70). In the non-pivoted position of the lever 70, the lever projection 76 can be sunk into the lever recess 78 (in particular in the form of a through-recess) in order to prevent the lever 70 from being pivoted unintentionally from the non-pivoted position. In order to rotate the lever 70 into the pivoted position, the lever 70 can be lifted at least in sections in order to eliminate the form fit between the lever projection 76 and the lever recess 78.

Fig. 11 shows that the lever 70 has curved sections 80, 82 (here in the form of curved sides) so that the lever 70 can be held comfortably without injury.

The present invention is particularly directed to a stent 20 that can be mounted and dismounted in a variety of ways, as a whole from all of the illustrations in the drawings. In the first mounting and dismounting mode, the first pin 26, which can be pivoted about its longitudinal axis L26, can preferably be moved into and out of the widened opening region 38 of the cuff-rail assembly 24 at the spreading arm 22 and can be pushed in and out of it into the slot-like opening region 40, in which it acts with its widened free end 28 from behind on at least one

side

42, 44 of said slot-like opening region 40. In the pivoted position of the first bolt 26, the first bolt 26 can preferably be moved into and out of the slot-like opening area 40 in the direction of its longitudinal axis L26 at least in a position directly adjacent to the widened opening area 38, in order to achieve a second mounting and dismounting manner.
