Hardware arrangement and door or window arrangement for such hardware arrangement

Description

[0001] The invention relates to a fitting arrangement for a door or window arrangement with features of claim 1 and a door or window arrangement with features of the dependent claim.

[0002] Fitting arrangements for door or window installations are known from the prior art. These are used, for example, to pivot a sash of a door or window installation onto a frame of the door or window installation.

[0003] Such fitting arrangements are disclosed, for example, in EP 2 703 587 B1, which shows a fitting arrangement with features of the preamble of claim 1, and EP 2 444 578 A2. Furthermore, EP 3 480 398 discloses a fitting arrangement with a fixed and a movable arm, which are coupled by means of several levers and can be connected to a frame made of extruded profiles by means of a connection system. GB 2 279 695 A and JP 2019-183462 A each disclose a fitting arrangement for pivotally connecting a sash to a frame, wherein the fitting arrangement has two levers that are coupled to each other by means of toothing.

[0004] A disadvantage of these fitting arrangements is that they often have a large number of elements and complex kinematics. This makes them particularly prone to failure. Due to the large number of elements and the complexity of the kinematics, these fitting arrangements also exhibit high wear.

[0005] It is therefore an object of the present invention to provide a fitting arrangement for a door or window arrangement and a door or window arrangement, thereby eliminating the above disadvantages.

[0006] The above problem is solved by a fitting arrangement with the features of claim 1. The fitting arrangement can be designed as a corner hinge. The fitting arrangement is designed and / or intended for an arrangement, in particular a concealed arrangement, in a door or window assembly with a frame and a sash pivotable relative to the frame. A concealed arrangement refers in particular to an arrangement in a rebate between the frame and the sash (window rebate or door rebate).

[0007] The fitting arrangement can be a rotary fitting arrangement or a tilt-and-turn fitting arrangement.

[0008] The fitting assembly includes a fastening element for attachment to the frame. The fastening element can be attached to the frame, for example, by screws. The fastening element can be designed as a corner bracket.

[0009] The fitting assembly comprises a main lever pivotally mounted on or attached to the fastening element. The main lever may be designed to bear at least part of the sash's weight (load transfer). In other words, the sash's weight can rest at least partially on the main lever. The main lever is designed to pivot about a main lever pivot axis that is fixed relative to the fastening element.

[0010] The fitting assembly includes a control lever pivotally mounted on or attached to the fastening element. The control lever is designed to pivot about a pivot axis that is fixed relative to the fastening element. The control lever is designed and / or intended to pivot the main lever.

[0011] This allows the fitting assembly to be implemented with only a few components, thus reducing its complexity. This simplifies the kinematics and allows for a particularly robust fitting assembly. Furthermore, it increases reliability.

[0012] According to the invention, the control lever comprises a drive section for driving the main lever, and the main lever comprises an output element fixedly arranged on the main lever. The output element can be rotationally fixed to the main lever, particularly with respect to the main lever pivot axis. The output element is arranged along the direction of gravity below the main lever (on its underside). The output element serves, in particular, as the output of the control lever or its drive section. The output element and the main lever can be designed as two separate components or as one component. The drive section and the output element can be in engagement with each other. The drive section and the output element can be in engagement with each other during the pivoting of the main lever and / or the control lever.

[0013] This allows the main lever to be pivoted using the control lever with simple means. Additional drive elements for pivoting the main lever are unnecessary.

[0014] According to a further development, the drive section and the driven element can have corresponding engagement sections. Specifically, the drive section and the driven element can be designed as gear teeth or gear segments (engagement sections).

[0015] Due to the engagement sections (gears or gear segments), a secure (mechanical) coupling between the control lever and the main lever or between the drive section and the output element can always be ensured.

[0016] According to a further development, the drive section can have a rounded extension. The output element can be (essentially) annular segment-shaped or U-shaped. The extension can engage with the annular segment-shaped or U-shaped output element during pivoting of the main lever and / or the control lever.

[0017] This allows for a robust (mechanical) coupling with only a few elements between the control lever and the main lever or between the drive section and the output element.

[0018] According to a further development, the fastening element can include a sliding section. The output element can be configured (e.g., arranged and / or aligned accordingly) to slide on the sliding section during pivoting of the main lever and / or the control lever. The output element specifically contacts the sliding section of the fastening element. In this way, the output element can serve as a support, so to speak, for the main lever.

[0019] This allows the force acting on the main lever, caused by the weight of the wing, to be at least partially transferred via the output element, particularly during pivoting of the main lever and / or the control lever. The load on the main lever can thus be distributed and evened out. This further reduces wear, especially on the main lever.

[0020] According to a further development, the sliding section can include a sliding plate. The output element and the sliding plate can be designed such that the output element slides on the sliding plate during pivoting of the main lever and / or the control lever. The sliding plate can be made of stainless steel.

[0021] This can facilitate the sliding of the output element on the sliding section or sliding plate and reduce wear, particularly due to friction between the output element and the sliding section or sliding plate during pivoting of the main lever and / or the control lever.

[0022] According to a further development, the fitting arrangement can include a control lever bolt. The control lever can be pivotally mounted on or to the fastening element by means of the control lever bolt. The control lever bolt can protrude from the control lever. The end face of the control lever bolt (protruding from the control lever) can form a sliding surface for the main lever, particularly during pivoting of the main lever and / or the control lever. The main lever can, in particular with its underside (relative to the direction of gravity), contact the end face of the control lever bolt. Thus, the control lever bolt can serve as a support for the main lever.

[0023] This allows the force acting on the main lever, caused by the weight of the wing, to be at least partially transferred via the control lever bolt, particularly during pivoting of the main lever and / or the control lever. The load on the main lever can thus be distributed and evened out. This further reduces wear, especially on the main lever.

[0024] Furthermore, the fitting arrangement according to the invention includes a corner hinge for attachment to the sash. The corner hinge can be pivotally mounted on or around the main lever, in particular by means of a main lever bolt. The corner hinge, and thus the sash connected to the corner hinge, can therefore be pivoted around the main lever, in particular around the main lever bolt (rotational movement).

[0025] This allows both the storage and the pivoting (rotating) movement of the corner hinge or the wing connected to the corner hinge to be achieved with simple means.

[0026] Furthermore, a drive pin is arranged on the control lever. The drive pin is slidably guided, at least partially (in particular completely), within a guide arranged in the corner hinge, and in particular by linear guidance. The guide can be designed as a linear guide. The guide can be designed as an elongated slot. The drive pin can be slidably arranged within the guide. This allows the control lever to pivot (rotate) when the sash or the corner hinge connected to the sash is pivoted, in particular about the main lever pin.

[0027] This allows the pivoting of the control lever and thus the drive of the main lever to be achieved with simple means.

[0028] The pivoting of the corner hinge or the sash connected to the corner hinge (opening the sash or moving the sash from a closed to an open position) results in, in particular, a pivoting of the control lever and thus a pivoting of the main lever on which the corner hinge is pivotally mounted. This pivoting of the corner hinge therefore results in a movement of the corner hinge superimposed on two pivoting movements. The superimposed pivoting movement consists, in particular, of a pivoting of the corner hinge (first rotational movement) about the main lever bolt and a pivoting of the corner hinge (second rotational movement) about the main lever pivot axis.

[0029] According to a further development, the main lever can at least partially, and in particular completely, cover the drive section and the output element in an open position and in a closed position of the fitting arrangement (with respect to the direction of gravity).

[0030] This allows the output element and the drive section to be shielded and protected from external influences (e.g. wind, dirt, water), especially from above (in relation to the direction of gravity).

[0031] According to a further development, the control lever can include a protective section. This protective section can be designed to at least partially, and in particular completely, engage behind the output element (and / or the drive section) in an open position of the fitting assembly. Thus, the protective section of the control lever can at least partially overlap the output element in an open position (in a direction perpendicular to the direction of gravity).

[0032] In this way, the output element (and / or the drive section) can be shielded and protected from external influences (e.g., wind, dirt, water), especially those coming from the outside through an open wing.

[0033] According to further training, the protective section can be designed as part of the drive section. Alternatively, it is conceivable that the protective section can be arranged directly adjacent to the drive section.

[0034] This allows the drive section and the protection section to be designed compactly, thus saving installation space.

[0035] The aforementioned problem is also solved by a door or window arrangement with the features of the dependent claim. The door or window arrangement comprises a frame and a sash pivotably mounted on the frame by means of a hardware arrangement as described above. Regarding the advantages achievable thereby, reference is made to the relevant descriptions of the hardware arrangement. The measures described in connection with the hardware arrangement and / or those explained below can be used to further develop the door or window arrangement.

[0036] The sash can be pivotally mounted on the fitting assembly and can be pivoted relative to the frame between a closed position (sash is in or on the frame plane) and an open position (sash is pivoted open relative to the frame plane).

[0037] The window arrangement can be either a casement window or a tilt-and-turn window. The door arrangement can be either a hinged door or a tilt-and-turn door.

[0038] According to further training, the fitting arrangement can be located at least partially, and in particular completely, in a rebate (window rebate or door rebate) between the frame and the sash.

[0039] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of an exemplary embodiment with reference to the drawings. The drawings show: Fig. 1 a partial and perspective view of a window arrangement with a hardware arrangement; Fig. 2 a perspective view of the hardware arrangement according to Figure 1 in a closed position; Fig. 3 a perspective view of the fitting arrangement according to Figure 1 in an open position; Fig. 4 an exploded view of the fitting arrangement according to Figure 1 ; Fig. 5 a top view of the fitting arrangement according to Figure 1 in the closed position; and Fig. 6 a top view of the fitting arrangement according to Figure 1 in the open position.

[0040] In the following description and in the figures, corresponding components and elements bear the same reference symbols. For the sake of clarity, not all reference symbols are shown in every figure.

[0041] Figure 1Figure 1 shows a perspective view of a window arrangement 12 with a hardware arrangement 10. The window arrangement 12 comprises a frame 14 and a sash 16 which can pivot relative to the frame 14. In this case, the sash 16 is pivotably mounted on the frame 14 by means of the hardware arrangement 10.

[0042] The hardware assembly 10 is arranged in a rebate 56 between the frame 14 and the sash 16 of the window assembly 12. The hardware assembly 10 is located in a lower corner (with respect to the direction of gravity 15) of the frame 14, in the rebate 56 (window rebate). The direction of gravity 15 is in Figure 1 indicated by an arrow.

[0043] Figure 2 shows a perspective view of the fitting arrangement 10 according to Figure 1 in a closed position 52 and Figure 3 in an open position 50.

[0044] The fitting assembly 10 includes a fastening element 18 for fastening the fitting assembly 10 to the frame 14. In the example, the fastening element 18 is designed as a corner bearing bracket.

[0045] The fitting assembly 10 further comprises a main lever 20 pivotably mounted on or attached to the fastening element 18. The main lever 20 is designed to pivot about a fixed main lever pivot axis 22. The fitting assembly 10 also comprises a control lever 24 pivotally mounted on or attached to the fastening element 18. The control lever 24 is designed to pivot about a fixed control lever pivot axis 26 (see figure). Figure 4 ) designed to swivel.

[0046] The fitting arrangement 10 comprises a corner hinge 42, which is connected to the sash 16 (see below). Figure 1The corner hinge 42 is pivotally mounted on or to the main lever 20 by means of a main lever bolt 44. Thus, the weight of the sash 16 (and the corner hinge 42) rests at least partially on the main lever 20.

[0047] Figure 4 shows an exploded view of the fitting assembly 10 according to Figure 1 , with corner band 42 for better clarity in Figure 4 not shown. The main lever pivot axis 22 and the control lever pivot axis 26 are each designed to be immovable with respect to the fastening element 18.

[0048] The control lever 24 has a drive section 28 for driving the main lever 20. On the main lever 20, on its underside (with respect to the direction of gravity 15; cf. Fig. 1 ), an output element 30 is arranged. The drive section 28 and the output element 30 are engaged with each other during the pivoting of the main lever 20 and / or the control lever 24.

[0049] In this example, the output element 30 is designed in the shape of an annular segment or a U-shape, and the drive section 28 of the control lever 24 has a rounded extension 32. During pivoting of the main lever 20 and / or the control lever 24, the extension 32 engages with the output element 30. The pivoting movement of the main lever 20 and / or the control lever 24 is described in detail below.

[0050] The control lever 24 has a protective section 54 which is designed to engage the output element 30 at least section by section in an open position 50 of the fitting arrangement 10 (cf. Figure 6 ).

[0051] The fastening element 18 has a sliding section 34. The sliding section 34 comprises a sliding plate 36. During pivoting of the main lever 20 and / or the control lever 24, the output element 30 slides on the sliding section 34 or the sliding plate 36.

[0052] The fitting assembly 10 has a control lever bolt 38. The control lever 24 is pivotably mounted on or to the fastening element 18 by means of the control lever bolt 38. In other words, the control lever 24 is designed to pivot about the control lever bolt 38. The control lever bolt 38 projects from the control lever 24 and, with its end face 40 projecting from the control lever 24, forms a sliding surface for the main lever 20.

[0053] This provides additional support for the main lever 20 by the output element 30 and the control lever bolt 38. This allows the weight of the wing 16 acting on the main lever 20 to be distributed more evenly, thus reducing wear.

[0054] The control lever 24 has a drive pin 46. The drive pin 46 engages in a guide 48 formed in the corner band 42 (see figure). Figure 2 and 3The drive bolt 46 is guided linearly within the corner band 42 by means of the guide 48. In this case, the guide 48 is designed in the form of an elongated hole.

[0055] Figure 5 shows a top view of the fitting arrangement 10 according to Figure 1 in the closed position 52 and Figure 6 shows a top view of the fitting arrangement 10 according to Figure 1 in the open position 50. The corner band 42 is in place for better clarity. Figure 5 and 6 not shown. The following explains the function of the fitting arrangement 10 and its kinematics: In the closed position 52 ( Figure 5 ) the fitting arrangement 10 contains the window arrangement 12 or the sash 16 (see Figure 1 ) also in a closed position. In other words, the wing 16 is closed or swung inwards. In the open position 50 ( Figure 6 The window arrangement 12 is also located in the fitting arrangement 10 (see below). Figure 1) also in an open position, or in other words, wing 16 is open or swung open.

[0056] If the window arrangement 12 or its sash 16 is now opened or swung open (from the in Figure 5 the closed position 52 shown in the Figure 6 When the wing 16 is moved to the open position 50 shown, the corner hinge 42 connected to the wing 16 is pivoted about the main lever bolt 44. Since the drive bolt 46 is guided linearly within the guide 48 of the corner hinge 42, the pivoting of the wing 16 and thus of the corner hinge 42 causes the control lever 24 to pivot about the control lever pivot axis 26.

[0057] As the control lever 24 pivots, the extension 32 moves about the control lever pivot axis 26 and engages the circular segment-shaped or U-shaped output element 30. This causes the output element 30, and thus the main lever 20, to pivot about the main lever pivot axis 22. The pivoting of the main lever 20 also pivots the main lever bolt 44 about the main lever pivot axis 22. Consequently, the corner band 42, which is pivotally mounted on the main lever bolt 44, also moves about the main lever pivot axis 22. This moves the corner band 42 in a direction perpendicular to the direction of gravity 15, away from the fastening element 18.

[0058] The movement of the corner hinge 42, or of the wing 16 connected to it, therefore corresponds to a superposition of two pivoting movements. The first pivoting movement corresponds to a pivoting (rotation) about the main lever bolt 44, and the second pivoting movement corresponds to a pivoting (rotation) about the main lever pivot axis 22.

[0059] In this case, the main lever 20 covers the drive section 28 and the output element 30 in both the closed position 52 and the open position 50, thus protecting them from above (with respect to the direction of gravity 15; cf. Figure 1 ).

[0060] Additionally, the protective section 54 shields the output element 30 and the extension 32 of the control lever 24 in the open position 50 of the fitting arrangement 10 along a direction oriented perpendicular to the direction of gravity 15 (in Figure 6"from above"). This protects the drive element 30 and the extension 32 in particular from external influences, which can act from the outside, for example, through the window arrangement 12 in an open position (or its open sash 16).
