Description

Technical Field

[0001] This invention relates to an unfolding device for connecting a fixed frame of a window or door to a sash of a window or door. The unfolding device includes a slotted track assembly that can be fixed to the sash and an unfolding arm for connecting the slotted track to the fixed frame. The slotted track assembly has a slotted track.

[0002] The present invention also relates to a window or door having such an unfolding device. Finally, the present invention relates to a method for installing a window or door. Background Technology

[0003] As is well known, a window or door sash is connected to a fixed frame of the window or door by an unfolding device. In particular, tiltable sashes, preferably rotatable and tiltable sashes ("rotatable-tilt-sashes"), are connected to the fixed frame by an unfolding device.

[0004] For example, an unfolding device of this type has been disclosed in EP 1 612 354 A2. EP 1 612 354 A2 discloses a tiltable fan with guide elements arranged thereon. The unfolding device connects the fan to a fixed frame. An auxiliary rod of the unfolding device can be arranged on the guide elements by means of a snap-fit ​​connection.

[0005] DE 85 25 718 U1 describes a detachable hinge connection between two fittings, such as a window, door, or similar object. The hinge connection includes a perforated leaf spring on the first fitting, which is subsequently engaged by a mushroom-head pin on the second fitting.

[0006] DE 40 40 233 A1 discloses a method for connecting a deployment device to a sway bearing. The deployment device is connected in the direction of the bearing axis. Here, the mounting position between the sway bearing and the fixed leg of the deployment device is secured by a spring-loaded, yieldable locking element that moves in the mounting direction.

[0007] DE 91 02 070 U1 discloses a device for releasably connecting an extendable arm to an auxiliary rod. Here, the auxiliary rod has a locking pawl that can be opened by swinging or bending a bearing pin of the extendable arm. In the installed position, the locking pawl engages with the bearing pin from behind. An arc-shaped operating mechanism is provided on the auxiliary rod. By pressing this operating mechanism, the locking pawl can be opened to disassemble the auxiliary rod.

[0008] EP 0 495 234 A1 discloses a method for connecting an extendable arm to a sliding member. The extendable arm has a mushroom-shaped pin, which is acted upon from behind by a spring element in the installed state. An opening is provided in the sliding member to allow the spring element to be pressed with a tool, thereby releasing the connection.

[0009] GB 2 253 007 A discloses an extendable arm for a window or door, which can be connected to a fixed frame or sash via a rotating rod connector. The rotating rod has an elongated rod-shaped member with a widened flange.

[0010] DE 30 17 483 A1 discloses a hangable deployable device for windows, doors, or the like. Here, a guide portion with a longitudinal groove is provided on the sash of the window, door, or the like, leading to a widened opening. The deployable device has a mushroom-shaped pin, the head of which can be inserted into the opening. The mushroom-shaped pin can then be pushed into the longitudinal groove. To prevent the mushroom-shaped pin from accidentally dislodging from the opening, a blocking member is provided, which can be installed in the area of ​​the opening, thereby closing the opening when the deployable device is in the installed state.

[0011] EP 0 128 371 A2 discloses an unfolding device for a tiltable fan. This unfolding device has an unfolding arm, the end of which is connected to a sliding member via a pin-hole connection. A rotatable fixing element mounted on the sliding member overlaps the end of the unfolding arm in its fixed position. Furthermore, EP 0 128 371 A2 discloses a push-pull mechanism for connecting a frame side by means of a bayonet connection device.

[0012] However, known deployable mechanisms are often either not intuitive or cannot be quickly installed or removed. In particular, deployable mechanisms are often installed by skilled window installers who prefer a quick installation method, but removed by less skilled installers who prefer a more intuitive fastening method. Summary of the Invention

[0013] Therefore, the object of the present invention is to provide a deployable device that is both intuitive and easy to install and disassemble quickly. Furthermore, the object of the present invention is to provide a window or door with such a deployable device, and a method for installing the window or door.

[0014] According to the present invention, the task is accomplished by the deployment device of the present invention, the window or door of the present invention, and the method of the present invention.

[0015] Therefore, the objective of the present invention is solved in a surprisingly simple way by the unfolding device described at the beginning, wherein the unfolding arm can be reversibly and loosely connected to the sleeve track assembly in at least two, and in particular exactly two, different connection methods.

[0016] Therefore, a connection method can be provided that allows the fan to be connected to the fixed frame very quickly, directly or indirectly, while also providing an alternative connection method that can be easily handled by even inexperienced personnel. Thus, the accessories of the present invention can cater to different target groups.

[0017] Further preferably, the deployable arm can be detached from the slot track assembly by at least two, and in particular exactly two, different disassembly methods.

[0018] Preferably, the deployable arm can be connected to the slot track assembly in at least two, and in particular exactly two, ways without the use of tools.

[0019] Further preferably, the deployable arm can be detached from the slot track assembly in at least two, and in particular exactly two, disassembly methods without tools.

[0020] The slotted track assembly is preferably engaged from the rear by the deploying arm in a segmented manner with the deploying device in the installed state. To provide this rear engagement, in the first connection configuration, the deploying arm is preferably pushed onto the slotted track assembly in a segmented manner so as to act on the slotted track assembly from the rear. In the second connection configuration, a portion of the deploying device is preferably designed to be oscillating, thus providing rear engagement in the non-deflected state and eliminating rear engagement in the deflected state.

[0021] Here, the unfolding device may have a first pin, one end of which has at least one protrusion to act from behind on at least one side, preferably both sides, of the slotted opening region of the first opening. For a first connection, in this case, the first opening also has a widened opening region into which the first pin can be inserted, and the first pin can be pushed from this opening region into the slotted opening region. For a second connection, in this case, the first pin and the slotted opening region have relative deflectability, particularly around the longitudinal axis of the first pin. The first pin is preferably configured non-rotationally symmetrical about its longitudinal axis, at least at its free end, such that the first pin does not act from behind on the slotted opening region in the deflected position and acts from behind on the slotted opening region in the undeflected position.

[0022] In other words, the first pin can form a bayonet lock with the slotted opening area to achieve the second connection method. To achieve the first connection method, the first pin can be pushed in and pushed out through the widened opening area connected to the slotted opening area.

[0023] Here, the widened opening region is designed to be large enough to allow the first pin to be inserted into the widened opening region in the non-deflected position. For this purpose, the width of the widened opening region corresponds at least to the maximum width of the free end of the first pin in the non-deflected position.

[0024] The width of the slotted opening region (particularly in the slotted opening region directly adjacent to the widened opening region) at least partially exceeds the maximum width of the free end of the first pin in the deflected position, but at least partially is less than the maximum width of the free end of the first pin in the non-deflected position.

[0025] Here, the width is preferably determined perpendicular to the longitudinal axis of the first pin, and in particular perpendicular to the longitudinal axis of the sleeve track.

[0026] Preferably, the first pin is arranged or formed on the deploying arm, and the first opening is arranged or formed on the sleeve track assembly. This makes the deploying device particularly easy to operate.

[0027] A further preferred embodiment is that the relative oscillation of the first pin and the first opening, particularly with the slotted opening region, is achieved by allowing the pin to deflect about its longitudinal axis. Thus, the deployment device can be implemented in a structurally particularly simple manner.

[0028] In other words, the following implementation is preferred: In this implementation, the deploying arm has a first pin that is widened at its free end, and the sleeve track assembly has a first opening with a widened opening area and a slotted opening area.

[0029] In order to achieve the first connection method, the widened end of the first pin can be inserted into the widened opening region, and the first pin can be moved into the slotted opening region, in which the first pin acts from behind on the side of the slotted opening region; and

[0030] In order to achieve the second connection method, the first pin can swing about its axis, and the widened end of the first pin is formed non-rotationally symmetrically about the longitudinal axis of the first pin, so that the first pin does not act on the side of the slotted area from the rear in the first swing position (deflection position) and acts on the side of the slotted area from the rear in the second swing position (non-deflection position), wherein the first pin can be inserted into the widened opening area in the second swing position.

[0031] To further simplify the design, the first opening, especially the widened opening area and the adjacent slotted opening area, can be constructed as a keyhole shape.

[0032] The first pin is preferably constructed in a T-shape at its free end to simplify its manufacture and reliably act from behind on the edge of the slotted area.

[0033] The maximum width of the free end of the first pin at the deflection position of the first pin can correspond to the diameter of the region near the free end of the first pin.

[0034] The first pin can be constructed in the form of a mushroom-head pin, with its head width reduced at least on one side, especially on both sides.

[0035] To facilitate the deflection of the pin, the deployment device may include a lever that is connected to the first pin at one end in a torsion-resistant manner.

[0036] The lever may have an over-torsion protection device to limit the lever's deflection relative to the spread arm to less than 180°, particularly less than 150°, and preferably less than 100°. This makes installation and removal more intuitive. The over-torsion protection device may have a protrusion that stops the lever at its deflected position on the spread arm and thus limits the maximum deflection. The protrusion may be constructed in the form of a chamfer on the lever.

[0037] The first opening may have an axially widened opening region at one end and a narrowed neck region at the other end, and at least one side, particularly both sides, may be elastically, i.e., springily, compressed to enable locking of the first pin behind the neck region (from the widened opening region). This allows for the implementation of an additional safety device by which the fan can be detachably held in an inclined position.

[0038] In the context of this invention, the term "axial" should be understood as "the longitudinal direction of the unfolding arm installed on the socket track in a position parallel to the socket track." Furthermore, in the context of this invention, the terms "upper," "lower," etc., should be considered as referring to the installation state of the window or door.

[0039] Preferably, the sleeve track assembly includes a connecting member fixed to the sleeve track, with a first opening formed in the connecting member. Different opening characteristics of the fan can be achieved by replacing the connecting member. In particular, the tilt width of the fan can be determined by the axial length of the slotted opening area. The connecting member is preferably integrally formed, i.e., a single piece.

[0040] Particularly preferred is that the connecting component is axially movable on the sleeve track, wherein the connecting component is fixed to the sleeve track at different axial positions by a locking device, particularly by locking teeth. This allows for adjustment of the fan's tilt width while the fan is suspended.

[0041] In a particularly preferred embodiment of the invention, the unfolding device has a limiting device that, after being moved according to the first connection method, axially fixes the unfolding arm to the sleeve track assembly. Here, the limiting device is preferably reversibly releaseable.

[0042] More preferably, the deployment device includes an auxiliary rod assembly with auxiliary rods. In this case, the deployment arm is part of the deployment shears, which consists of the deployment arm and the auxiliary rods.

[0043] The auxiliary rod assembly is swayable and may have a second opening for receiving a second pin of the limiting device.

[0044] The auxiliary rod assembly may include a spring element. The spring element is preferably constructed in the form of a leaf spring.

[0045] The spring element may have a stop for the second pin at least in sections.

[0046] The spring element may include a portion of a second opening. This portion of the second opening may form the stop for the second pin.

[0047] The auxiliary rod may (especially on the end side) have a groove for abutting against the second pin in the locked position. This groove may form part of the second opening.

[0048] Particularly preferred is that the spring element can be compressed at least in sections (especially toward the sleeve track), thereby allowing the second pin to be axially removed from the second opening.

[0049] The second pin is preferably arranged or formed on the first unfolding arm, and the auxiliary rod assembly is preferably arranged or formed on the sleeve track.

[0050] The first pin and / or the second pin can have any cross-section. However, it is preferred that the first pin and / or the second pin have a predominantly circular cross-section in their longitudinal extensions.

[0051] Furthermore, the objective of the present invention is achieved through a window or door equipped with an unfolding device, as described herein, for connecting a fixed frame to the sash of a window or door.

[0052] Here, the window or door preferably has a tiltable sash. The latching track assembly is then preferably arranged on the upper support of the sash. The deployable arm is connected to the fixed frame, particularly via upper corner supports. The deployable arm may be referred to as an "axe arm," and the latching track may be referred to as an "axe latch."

[0053] Finally, the objective according to the invention is achieved by a method for installing, in particular, the deployment device described above, comprising the following steps:

[0054] A) Connect the unfolding arm to the fixed frame and fix the sleeve rail assembly to the fan;

[0055] B) Insert the first pin of the unfolding arm into the widened opening area of ​​the first opening of the sleeve track assembly;

[0056] C) The fan is moved axially such that the first pin is inserted into the slotted opening region of the first opening, in which the first pin acts at least partially from behind on the edge of the slotted opening region with its widened free end, wherein the axial movement of the fan continues until the limiting device locks.

[0057] In step A), the sleeve track assembly is preferably fixed to the upper support rod of the fan. The connection between the unfolding arm and the fixed frame is preferably achieved through the upper corner support.

[0058] In step B), the upper side of the fan is preferably deflected toward the fixed frame to insert the first pin into the widened opening area. Here, the fan can be supported at the lower corner. In particular, the fan can be supported at the lower corner by a lower corner support on the fixed frame.

[0059] In step B), the insertion of the first pin is preferably performed when the upper side of the fan is deflected toward the fixed frame.

[0060] In step C), the fan is preferably moved by deflecting the upper side of the fan away from the fixed frame.

[0061] Method steps A), B) and / or C) are preferably performed with the fan rotated open, wherein the fan is arranged on a fixed frame, particularly by means of a lower corner support.

[0062] The unfolding device, window, or door used in carrying out the method of the present invention may have the features described above and / or below.

[0063] Further advantages of the invention can be seen from the specification and drawings. Similarly, the features described above and those to be described in detail below can also be used alone or in any combination according to the invention. The illustrated and described embodiments should not be construed as exhaustive, but rather as exemplary in illustrating the invention. Attached Figure Description

[0080] Figure 1 The upper part of window 10 is shown, which has a fixed frame 12 and a sash 14 arranged on the fixed frame 12. The sash 14 has an upper support rod 16. An unfolding device 20 is provided between the upper support rod 16 and the upper corner support 18 for holding the sash 14 tiltably and / or rotatably open on the fixed frame 12.

[0081] Figure 2 The deployment device 20 is shown. This deployment device has a deployment arm 22, which is supported by an upper corner bracket 18 (see...). Figure 1 ) and fixed frame 12 (see Figure 1) connection. On the upper strut 16, especially on the upper strut 16 (see upper strut 16) Figure 1 The fitting part slot (not shown) is provided with a sleeve track assembly 24 (see Figure 1 The sector 14 (see) Figure 1 The suspension of the arm is achieved by connecting the unfolding arm 22 to the sleeve track assembly 24.

[0082] The deploying arm 22 has a first pin 26, the free end 28 of which is T-shaped and widened. Additionally, the deploying arm 22 has a second pin 30. The slot track assembly 24 has a slot track 32. A connecting member 34 is provided on the slot track 32. This connecting member 34 has a first opening 36 for receiving the first pin 26. The first opening 36 has a widened opening region 38 for inserting the first pin 26 and a slotted opening region 40 with sides 42, 44. The first pin 26 is designed to hook the sides 42, 44 from behind with its T-shaped widened end 28 when the deploying device 20 is in the installed state.

[0083] A neck region 46 is provided in the slotted opening region 40. The neck region 46 is narrowed and therefore, when the first pin 26 moves from the inclined position 48 (in which the fan 14 [see...]),... Figure 1 When the device is in the tilted position and moves along the longitudinal direction of the slot track 32, the first pin 26 is difficult to pass through. Thus, impact protection is achieved for the deployment device 20 in the tilted position 48.

[0084] An auxiliary rod assembly 50 is mounted on the slot track 32. The auxiliary rod assembly 50 can be driven by a swing bearing 52. Figure 2 The indicated position (parallel to the longitudinal axis of the sleeve track 32) is deflected outwards. The auxiliary rod assembly 50 has an auxiliary rod 54, which forms an unfolding shear with the unfolding arm 22 when the unfolding device 20 is installed.

[0085] Furthermore, the auxiliary rod 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 deployment device 20, the second pin 30 continues to rest against a groove 60 in the auxiliary rod 54. The groove 60 here forms a portion of the second opening 58. The groove 60 is preferably at least partially constructed as a semicircle.

[0086] 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 towards the sleeve track 32. Once 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 rod assembly 50, together with the second pin 30, forms a limiting device 64.

[0087] The unfolding device 20 is designed to provide various users with the ability to unfold the fan 14 (see Figure 1 Install or remove from fixed frame 12 (see) Figure 1 This allows for a simple and quick process. To this end, the deployable arm 22 can be mounted on or removed from the socket rail assembly 24 in at least two different ways, and in particular exactly two ways.

[0088] exist Figures 3a to 5b The image shows a first connection method for the installation of the unfolding arm 22 and the sleeve track assembly 24.

[0089] Figure 3a The unfolding device 20 is shown, wherein the sleeve track assembly 24 is mounted on the fan 14 and the unfolding arm 22 is mounted on the upper corner support 18 (see...). Figure 1 The first pin 26 is at the same axial height as the widened opening region 38, so the first pin 26 can enter the widened opening region 38 along its longitudinal axis L26 in the next installation step. For this purpose, 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. 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 sleeve track 32.

[0090] Figure 3b This shows how to implement the first pin 26 (see...) Figure 3a ) and the widened opening area 38 (see Figure 3a The axial correspondence of ). According to Figure 3b In the rotated open position, the fan 14 is lifted on its free side. Here, the fan 14 is preferably connected to the fixed frame 12 at the lower corner support 66. If the fan 14 is fixed to the lower corner support 66, Figure 3b The swinging motion shown will be automatically performed by lifting the fan 14.

[0091] Figure 4 The next installation step is shown, in which the first pin 26 is recessed into the widened opening area 38. This recessing has already occurred due to the lifting of the fan 14 (see...). Figure 3b ).

[0092] Figure 4 As further shown, the second pin 30 compresses the spring element 56, particularly in the region of its ramp 62. Thus, the spring element 56 is tensioned.

[0093] Figure 5a The next installation step is shown, in which the first pin 26 is moved into the slotted opening region 40, thereby extending its widened free end 28 (see...). Figure 2) acting from the rear on the sides 42, 44 of the slotted opening region 40 (see Figure 2 Therefore, the unfolding arm 22 is locked onto the sleeve track assembly 24 in the direction of the longitudinal axis L26 of the first pin 26.

[0094] In addition, the axial displacement of the deployable arm 22 causes the second pin 30 (see also) Figure 2 ) Sink into the second opening 58 (see Figure 2 In this configuration, the spring element 56 is released and secures the deploying arm 22, preventing axial movement relative to the sleeve rail assembly 24. Therefore, the deploying arm 22 is secured in all three spatial directions to prevent disassembly relative to the sleeve rail assembly 24.

[0095] Figure 5b As shown, the first pin 26 (see Figure 5a ) Move into the slotted opening area 40 (see Figure 5a This is accomplished by swinging the upper side of the fan 14 away from the fixed frame 12. If the fan 14 is fixed to the lower corner support 66, this movement is automatic when the fan 14 descends. In other words, the unfolding arm 22 (see...) Figure 5a It is locked to the socket track assembly 24 by yielding to the weight of the fan 14 itself (see Figure 5a This allows the deployable arm to move slightly downwards on the free side.

[0096] Figures 6 to 8 The first disassembly method of the unfolding device 20 is shown.

[0097] Figure 6 The diagram illustrates 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 axial movement of the second pin 30. Alternatively, this pressing can also be performed with fingers without a tool. The pressing is preferably performed towards the sleeve track 32.

[0098] Figure 7a The following axial displacement of the unfolding arm 22 relative to the sleeve track assembly 24 is shown. As a result, the first pin 26 no longer acts from the rear on the slotted opening region 40 (see also...). Figure 2 ). Figure 7a The position of window 10 in the middle and Figure 4 The corresponding position in the middle.

[0099] Figure 7b This indicates that, for this axial displacement, the upper side of fan 14 swings toward the fixed frame 12.

[0100] Figure 8 This illustrates how the deployable arm 22 is ultimately removed upwards. Here, the first pin 26 is pulled out from the widened opening area 38. Figure 8The position of window 10 in the middle and Figure 3a The corresponding position in the middle.

[0101] The first installation and first removal method is particularly advantageous for experienced window installers because it can be done quickly and is also especially safe. This is achieved by using the first pin 26 (see...) Figure 5a ) retracts back to the slotted opening area 40 (see Figure 5a ), can grab fan 14 (see Figure 5b The unintentional reduction of ).

[0102] Figures 9 to 11 A second method of installing or removing the deployment device 20 is shown. This second method of installation or removal is very intuitive and therefore particularly suitable for inexperienced installers.

[0103] Figure 9 As shown, the first pin 26 is torsionally connected to the lever 70. By turning the lever 70, the first pin 26 is turned during the first disassembly step, bringing it to the turned, unlocked position.

[0104] Lever 70 has an over-torque protection device 71 (see in particular) Figure 8 ), here is the form of a bevel.

[0105] Figure 10 A further disassembly step is shown, in which the deploying arm 22, together with the first pin 26, is lifted from the slotted track assembly 24. Because the first pin 26 is swung, the widened free end 28 of the first pin 26 no longer acts from behind on the edge of the slotted opening region 40, thereby allowing the first pin 26 to move in the direction of its longitudinal axis L26. Here, the width B40 of the slotted opening region 40 is at least partially 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 non-deflected position (see...). Figure 3a ).

[0106] Thus, by swinging the lever 70, the first pin 26 can be pulled out from the slotted opening area 40 in the swinged position to disassemble the deployable arm 22. Conversely, in the swinged position, the first pin 26 can be inserted into the slotted opening area 40 and then swing to install the first deployable arm 22.

[0107] With the extended arm 22 in the installed state, the first pin 26 moves in the slotted opening area 40 to allow movement from the closed position of the fan 14 (see...). Figure 1However, there, fan 14 is shown in the rotated open position to reach the tilted position. Here, the maximum tilt width can be achieved by the axial displacement of the connecting member 34. In order to lock the connecting member 34 in different axial positions, the latter has a locking device 72.

[0108] The first pin 26 can be riveted to the lever 70. The lever 70 may include a spring section 74 to create a limiting pressure of the lever 70 on the deployable arm 22. The spring section 74 can be pressed down during riveting.

[0109] The lever 70 may include (particularly at its free end) a lever protrusion 76 (preferably in the form of a chamfer on the lever 70). In the non-oscillating position of the lever 70, the lever protrusion 76 may be recessed into the lever groove 78 (particularly in the form of a through groove) to prevent the lever 70 from unintentionally oscillating in the non-oscillating position. To rotate the lever 70 into the oscillating position, the lever 70 may be lifted at least in sections to eliminate the form fit between the lever protrusion 76 and the lever groove 78.

[0110] Figure 11 As shown, lever 70 has curved sections 80, 82 (here in the form of curved sides) so that lever 70 can be held comfortably without injury.
