A spreading device for a tiltable fan is known from EP 0 128 371 A2. The spreading device has a spreading arm, which is connected at its fan-side end to the slider via a pin-hole connection. In its fixed position, the rotatable fastening element mounted on the slide overlaps the end of the spreading arm. Furthermore, EP 0 128 371 A2 discloses a push-pull mechanism connecting the frame sides by means of a bayonet connection.

However, known deployment devices are often either not intuitive or cannot be quickly installed or removed. In particular, spreaders are often installed by skilled window installers desiring a quick means of installation, but are removed by unskilled installers who prefer a more intuitive means of fastening.

Contents of the invention

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

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

The object of the invention is thus solved in a surprisingly simple manner by the opening device described at the outset, in which the opening arm can be reversibly releasably connected to the collar rail in at least two, in particular exactly two, different ways of connection. Component connections.

Thereby, a connection can be provided which makes it possible to connect the leaf very quickly, directly or indirectly, to the fixing frame, and at the same time another connection which makes it possible also to be connected by unskilled Handlers handle it with ease. Thus, the accessory of the invention can address different target groups.

It is further preferred that the deployment arm can be released from the collar rail assembly in at least two, in particular exactly two, different ways of detachment.

Preferably, the deployment arm can be connected to the socket rail assembly in at least two, in particular exactly two, ways without the use of tools.

It is further preferred that the deployment arm can be detached from the collar rail assembly without tools in at least two, in particular exactly two, ways of detachment.

Preferably in the installed state of the spreading device, the collar rail assembly is engaged in sections by the spreading arm from behind. In order to provide such a rear fit, the deployment arm is preferably partially pushed onto the socket rail assembly in the first connection type in order to act partially on the socket rail assembly from behind. In the second connection type, a part of the stent is preferably designed to be pivotable, so that there is a back fit in the non-deflected state and no back fit in the deflected state.

In this case, the spreading device can have a first pin having at least one projection at one end in order to engage from behind at least one side, preferably both sides, of the slot-shaped opening region of the first opening. In order to realize the first connection type, in this case the first opening also has a widened opening area, into which the first pin can be inserted and from which the first pin can be pushed into the slot-shaped opening area. In order to realize the second type of connection, in this case the first pin is relatively deflectable relative to the slot-shaped opening region, in particular around the longitudinal axis of the first pin. The first pin is preferably formed rotationally asymmetrically at least at its free end with respect to its longitudinal axis, so that it does not act on the slot-shaped opening area from behind in the deflected position and from behind in the undeflected position. Acts on the slot-shaped opening area.

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

In this case, the widened opening area is designed sufficiently large to allow insertion of the first pin in the non-deflected position into the widened opening area. For this purpose, 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-shaped opening region (in particular in the slot-shaped opening region directly adjacent to the widened opening region) exceeds at least in sections the maximum width of the free end of the first pin in the deflected position, but at least in sections ground below the maximum width of the free end of the first pin in the non-deflected position.

In this case, the width is preferably determined perpendicular to the longitudinal axis of the first pin, in particular perpendicular to the longitudinal axis of the socket track.

Preferably, the first pin is arranged or formed on the deployment arm and the first opening is arranged or formed on the socket track assembly. This makes the spreading 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-shaped opening region, is achieved in that the pin is pivotable about its longitudinal axis. As a result, the deployment device can be realized in a structurally particularly simple manner.

In other words, an embodiment is preferred in which the deployment arm has a first pin widened at its free end and the socket track assembly has a first opening with a widened The opening area and the 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 be moved into the slot-shaped opening area, in which the first pin The pin acts from behind on the sides of the slot-like opening area; and

Wherein, in order to realize the second connection mode, the first pin can swing around its axis, and the widened end of the first pin is formed non-rotationally symmetrically with respect to the longitudinal axis of the first pin, so that the first pin is in the first In the swivel position (deflected position), the side of the slot-shaped area is not acted from behind and in the second swiveled position (non-deflected position), the first pin acts on the side of the slot-shaped area from behind, wherein the first pin is in the second swivel position. The position can be inserted into the widened opening area.

In order to further simplify the design, the first opening, in particular the widened opening area and the immediately adjacent slot-shaped opening area, can be designed in the form of a keyhole.

The first pin is preferably T-shaped at its free end in order to simplify its production and to engage reliably behind the edge of the slot-like 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 vicinity of the free end of the first pin.

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

In order to facilitate the deflection of the pin, the spreading device can comprise a lever which is connected at one end in a rotationally fixed manner to the first pin.

The lever can have an overtwist protection device in order to limit the pivotability of the lever to less than 180°, in particular less than 150°, preferably less than 100° relative to the spreading arm. This makes installation and removal much more intuitive. The overtwist protection device can have a projection which, in the deflected position of the lever, stops against the spreading arm and thus limits the maximum deflection. The projection can be configured in the form of a chamfer of the lever.

The first opening can axially have a widened opening area at one end and a narrowed neck area at the other end, at least one side, in particular both sides, of which can be pressed elastically, that is to say springing, To make locking of the first pin behind this neck area possible (from the widened opening area). As a result, an additional safety device can be realized by means of which the leaf can be detachably held in the tilted position.

The term "axial" is to be understood in the sense of the present invention as "the longitudinal direction of the deployment arm mounted on the collar rail in a position parallel to the collar rail". Furthermore, in the sense of the present invention, the terms "upper", "lower", etc. shall be regarded as referring to the installed state of the window or door.

Preferably, the socket track assembly includes a connecting member secured to the socket track, the first opening being formed in the connecting member. By changing the connecting parts, different opening characteristics of the fan can be achieved. In particular, the oblique width of the fan can be determined by the axial length of the slot-shaped opening region. The connection part is preferably formed in one piece, ie in one piece.

Particularly preferably, the connecting part is arranged axially displaceable on the socket rail, wherein the connecting part can be fixed in different axial positions on the socket rail by a locking device, in particular by locking teeth. As a result, the tilt width of the fan can be adjusted when the fan is hung.

In a particularly preferred embodiment of the invention, the spreading device has a stop device which, after movement according to the first connection, axially fixes the spreading arm on the collar rail assembly. In this case, the locking device is preferably reversibly detachable.

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 the deployment shears consisting of the deployment arm and the auxiliary rod.

The auxiliary lever assembly is pivotable and may have a second opening for receiving a second pin of the limiter.

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

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

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

The auxiliary lever can have, in particular on the end side, a recess for abutting against the second pin in the locked position. The groove may form part of the second opening.

Particularly preferably, the spring element can be pressed at least in sections, in particular towards the collar rail, so that the second pin can be moved axially out of the second opening.

The second pin is preferably arranged or formed on the first deployment arm and the auxiliary rod assembly arrangement is preferably arranged or formed on the socket track.

The first pin and/or the second pin can have any desired cross-section. However, it is preferred that the first pin and/or the second pin has a predominantly circular cross-section in its longitudinal extension.

Furthermore, the object of the invention is solved by a window or door having a deployment device described here for connecting a fastening frame to a window or door leaf.

In this case, the window or door preferably has a tiltable leaf. The socket track assembly is then preferably arranged on the upper strut of the fan. The deployment arms are connected to the fixed frame, in particular via upper corner supports. The deployment arm may be referred to as the "axe arm" and the socket track may be referred to as the "axe socket".

Finally, the object according to the invention is solved by a method for installing, in particular, a deployment device as described above, which has the following method steps:

A) Connect the deployment arm to the fixed frame and fix the socket track assembly on the fan;

B) inserting the first pin of the deployment arm into the widened opening area of the first opening of the socket track assembly;

C) The leaf is moved in the axial direction, so that the first pin is inserted into the slot-shaped opening region of the first opening, in which the first pin is at least partially viewed from behind with its widened free end Acts on the edge of the slot-shaped opening area, wherein the axial displacement of the leaf is carried out until the locking of the locking device.

In method step A), the collar rail assembly is preferably fastened to the upper strut of the fan. The connection of the spreading arm to the fixed frame is preferably effected via the upper corner mounts.

In method step B), the upper side of the leaf is preferably pivoted towards the fastening frame in order to insert the first pin into the widened opening region.

Detailed ways

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 strut 16 . Between the upper strut 16 and the upper corner support 18 is arranged a spreading device 20 for holding the leaf 14 on the fixed frame 12 in a tiltable and/or rotatable open manner.

FIG. 2 shows the deployment device 20 . The spreading device has a spreading arm 22 which is connected to the fastening frame 12 (see FIG. 1 ) via an upper corner support 18 (see FIG. 1 ). A pocket track assembly 24 (see FIG. 1 ) is provided on the upper strut 16 , particularly on a fitting portion slot (not shown) of the upper strut 16 (see FIG. 1 ). The suspension of the fan 14 (see FIG. 1 ) is achieved through the connection of the deployment arm 22 to the socket track assembly 24 .

The deployment arm 22 has a first pin 26 whose free end 28 is widened in a T-shape. Furthermore, the deployment arm 22 has a second pin 30 . The socket track assembly 24 has a socket track 32 . A connecting part 34 is arranged on the socket rail 32 . The connection 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 an adjoining slot-shaped opening area 40 with sides 42 , 44 . The first pin 26 is designed such that its T-shaped widened end 28 hooks behind the sides 42 , 44 in the installed state of the spreading device 20 .

A neck region 46 is located in the slot-shaped opening region 40 . The neck region 46 narrows and thus causes the first pin 26 to move as it moves in the longitudinal direction of the collar track 32 from the tilted position 48 in which the fan 14 [see FIG. 1 ] is in the tilted position. 26 is difficult to pass. As a result, impact protection of the splay device 20 in the tilted position 48 is achieved.

An auxiliary rod assembly 50 is provided on the socket track 32 . The auxiliary rod assembly 50 can be pivoted out of the position shown in FIG. 2 (parallel to the longitudinal axis of the socket track 32 ) via the pivot 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 lever assembly 50 includes a spring element 56 . A second opening 58 is formed in the spring element 56 for receiving the second pin 30 . In the installed position of the splay device 20 , the second pin 30 continues to bear against the groove 60 of the auxiliary rod 54 . The groove 60 here forms part of the second opening 58 . The recess 60 is preferably semicircular at least in sections.

To facilitate the entry of the second pin 30 into the second opening 58 during 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 socket rail 32 . As soon as the second pin 30 enters the second opening 58 , the spring element 56 springs back and locks the second pin 30 axially. Therefore, the auxiliary lever assembly 50 forms a limiting device 64 together with the second pin 30 .

The deployment device 20 is intended to provide various users with a simple and quick possibility of mounting or dismounting 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 detached from the collar rail assembly 24 in at least two different ways, in particular exactly two ways.

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

Figure 3a shows the deployment device 20 with the collar track assembly 24 mounted on the sash 14 and the deployment arm 22 mounted on the upper corner mount 18 (see Figure 1). The first pin 26 is axially at the same level as the widened opening area 38 , so that the first pin 26 can enter the widened opening area 38 in the direction of its longitudinal axis L26 in a next assembly 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 non-deflected position shown. 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 socket track 32 .

FIG. 3b shows how the axial correspondence of the first pin 26 (see FIG. 3a ) to the widened opening area 38 (see FIG. 3a ) is achieved. According to FIG. 3 b , the leaf 14 is lifted on its free side in the swivel open position. In this case, the leaf 14 is preferably connected to the fastening frame 12 at the lower corner support 66 . If the sash 14 is fastened on the lower corner support 66, the pivoting movement shown in FIG. 3b takes place automatically by raising said sash 14.

FIG. 4 shows the next installation step in which the first pin 26 is sunk into the widened opening region 38 . Here, the sinking already takes place due to the lifting of the fan 14 (see FIG. 3b ).

FIG. 4 further shows that the second pin 30 presses against the spring element 56 , in particular in the region of its ramp 62 . As a result, the spring element 56 is tensioned.

FIG. 5 a shows the next installation step, in which the first pin 26 is moved into the slot-like opening area 40 so that it acts on the pin from behind with its widened free end 28 (see FIG. 2 ). The side surfaces 42 , 44 of the slot-shaped opening region 40 (see FIG. 2 ). Thus, the deployment arm 22 is locked on the socket track assembly 24 in the direction of the longitudinal axis L26 of the first pin 26 .

Furthermore, axial displacement of the deployment arm 22 causes the second pin 30 (see also FIG. 2 ) to sink into the second opening 58 (see FIG. 2 ). The spring element 56 is released and secures the deployment arm 22 against axial movement relative to the socket track assembly 24 . Thus, deployment arm 22 is secured against disassembly relative to collar track assembly 24 in all three spatial directions.

FIG. 5 b shows that moving the first pin 26 (see FIG. 5 a ) into the slot-shaped opening area 40 (see FIG. 5 a ) is accomplished by pivoting the upper side of the leaf 14 away from the fixing frame 12 . If the sash 14 is fixed on the lower corner support 66, this movement takes place automatically when the sash 14 is lowered. In other words, the deployment arm 22 (see FIG. 5a ) is locked to the collar track assembly 24 (see FIG. 5a ) by yielding to the weight of the sash 14 itself so that the deployment arm can move slightly downward on the free side.

6 to 8 show a first disassembly of the deployment device 20 .

FIG. 6 shows a first disassembly step in which the spring element 56 is squeezed by a tool 68 , here in the form of a screwdriver, to allow the axial movement of the second pin 30 . Alternatively, the squeezing can also be performed with fingers without tools. This pressing preferably takes place towards the collar rail 32 .

FIG. 7 a shows the subsequent axial displacement of deployment arm 22 relative to collar track assembly 24 . As a result, the first pin 26 no longer acts on the slot-shaped opening region 40 from behind (see also FIG. 2 ). The position of the window 10 in FIG. 7 a corresponds to that in FIG. 4 .

FIG. 7 b shows that, for this axial displacement, the upper side of the fan 14 swings towards the fixed frame 12 .

Figure 8 shows how the deployment arm 22 is finally withdrawn upwards. In this case, the first pin 26 is pulled out of the widened opening region 38 . The position of the window 10 in Fig. 8 corresponds to that in Fig. 3a.

The first method of installation and removal is particularly advantageous for experienced window workers, since it can be carried out quickly and here also in a particularly safe manner. Unintentional lowering of the leaf 14 (see FIG. 5b ) can be caught by retracting the first pin 26 (see FIG. 5a ) into the slot-shaped opening region 40 (see FIG. 5a ).

9 to 11 show a second way of mounting or dismounting the deployment device 20 . This second way of installation or removal is very intuitive and 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 activating the lever 70 , the first pin 26 is oscillated in a first removal step into the oscillating, unlocked position.

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

FIG. 10 shows a further disassembly step in which the deployment arm 22 is lifted from the collar track assembly 24 together with the first pin 26 . Since the first pin 26 is swiveled, the widened free end 28 of the first pin 26 no longer acts on the edge of the slot-shaped opening area 40 from behind, so that the first pin 26 can be positioned in the direction of its longitudinal axis L26. direction to move. Here, the width B40 of the slot-shaped opening region 40 is 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 smaller than the free end 28 of the first pin 26 in the non-deflected position. Maximum width B28-1 of end 28 (see FIG. 3a).

Thus, by pivoting the lever 70 , the first pin 26 can be pulled out of the slot-shaped opening region 40 in the pivoted position in order to dismantle the deployment arm 22 . Conversely, in the pivoted position, the first pin 26 can be inserted into the slot-shaped opening region 40 and then pivoted in order to mount the first deployment arm 22 .

In the mounted state of the deployment arm 22, the first pin 26 is moved in the slot-shaped opening area 40 in order to reach the tilted position from the closed position of the leaf 14 (see FIG. 1; but there, the leaf 14 is shown in a rotated open position). Location. In this case, the maximum bevel 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 can be riveted on 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 . Spring section 74 can be pressed down during riveting.

The lever 70 may comprise (in particular at its free end) a lever protrusion 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 sink into the lever recess 78 , in particular in the form of a through-recess, in order to prevent the lever 70 from being unintentionally pivoted from the non-pivoted position. In order to rotate the lever 70 into the swivel 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.

Taken as a whole in all the figures of the drawings, the invention relates in particular to a stent 20 which can be mounted and disassembled in various ways. In a first mounting and dismounting mode, the first pin 26, which is pivotable about its longitudinal axis L26, is preferably movable in and out of the widened opening area 38 of the socket track assembly 24 at the deployment arm 22, and can be pushed in from there. and pushed out into the slot-shaped opening area 40 , in which it engages with its widened free end 28 on at least one side 42 , 44 of the slot-shaped opening area 40 from behind. In the swivel position of the first pin 26 , the first pin 26 is preferably movable in the direction of its longitudinal axis L26 at least at the position of the slot-shaped opening area 40 , in particular directly adjacent to the widened opening area 38 . Move out to this slot-like open area for a second way of mounting and dismounting. Further preferably, the deployment device 20 includes a limiting device 64, the limiting device includes a second pin 30 on the deployment arm 22, the second pin can be locked on the free end of the auxiliary rod assembly 50 of the socket track assembly 24 superior. Furthermore, the invention relates to a window 10 or door, in particular a tiltable window or door, comprising a fixed frame 12 and such a deployment device 20 which is preferably arranged on the upper side of the window or door leaf 14 . Finally, the invention preferably relates to a method of installing or dismounting such a window 10 or door, wherein the upper side of the window or door 14 is swung away from or towards the fixed frame 12 in order to move the first pin 26 into and out of the slot-like opening Area 40.
