Corner bearing for concealed mounting and window or french window with such a corner bearing

Abstract

A corner bearing (3) for the concealed mounting of a sash (2) that pivots against a frame (1) has a guide (20) for moving the sash (2) into a parallel resting position. The guide (20) is designed as an elongated hole (22) on a support arm (14) of a link assembly (12) and guides a guide pin (21) connected to the sash (2). This allows the sash (2) to be moved into the parallel resting position in addition to a closed position, a rotating position, and, if applicable, a tilting position.

Description

[0001] The invention relates to a corner hinge for the concealed mounting of a sash pivotable between a closed position and a rotation position against a frame of a window, door, or the like, comprising a frame-side fitting part, a sash-side fitting part, and a linkage connecting the fitting parts, a control link of the linkage assembly mounted in the frame-side fitting part and on the sash-side fitting part, and a support arm of the linkage assembly articulated to the fitting parts. The invention further relates to a window or French door with a sash pivotable against a frame and with a corner hinge according to one of the preceding claims, wherein the sash is movable between a closed position within the frame, a parallel position resting in its plane away from the frame, and a rotation position pivoted away from the frame.

[0002] A corner hinge designed for concealed installation is known from EP 2 835 483 A1. In this corner hinge, two pivoting arms, which can be rotated about a common axis of rotation, have longitudinal guides in the hardware components, the frame, or the sash. A sliding disc is arranged between the pivoting arms on the axis of rotation. This results in a very low-friction corner hinge. However, ventilation control of the window equipped with this corner hinge is very limited in the closed and open positions.

[0003] From EP 2 708 692 A2, a fitting for concealed installation in the rebate between a sash and a frame is known. A corner hinge of this fitting has a sash support arm and a control lever coupled to it. The control lever is connected to a sash pivot bearing via a connecting link, so that the pivot angle of the sash is increased beyond 90° to 135°. With this fitting as well, ventilation control via the closed and turn positions is only possible to a limited extent.

[0004] From EP 1 422 372 A1, a window with a fitting and a corner hinge is known in which the sash can be moved between a closed position within the frame, a turn position turned away from the frame, and a tilt position tilted away from the frame, into a parallel position. In the parallel position, the sash is essentially parallel to the frame. The various switching positions allow for a wide range of ventilation controls. In the parallel position, the sash is held by locking bolts located in guides of strike plates on the fitting. However, the corner hinge cannot be concealed between the frame and the sash and is therefore visible when the sash is in the closed position.

[0005] The invention addresses the problem of further developing a corner hinge of the type mentioned above in such a way that it enables particularly versatile ventilation control and can be concealed between the frame and the sash. Furthermore, the invention addresses the problem of designing a window or French door equipped with the corner hinge in such a way that ventilation is reliably prevented in the closed position.

[0006] The first problem is solved according to the invention by the fact that the support arm has a guide arranged transversely to its longest extent for the sash-side fitting part at its end facing away from the frame-side fitting part, so that the sash-side fitting part can be moved from the frame-side fitting part into a parallel parking position.

[0007] This design allows the guide in the support arm to move the two fitting components away from each other relative to one another. This relative movement enables the movement of one sash of the window equipped with the corner hinge according to the invention into the parallel opening position. Nevertheless, the corner hinge can be concealed between the frame and the sash. Thanks to the invention, the corner hinge allows for particularly versatile ventilation control.

[0008] The guide could, for example, be designed as a guide rail attached to the support arm or the sash-side fitting. According to an advantageous embodiment of the invention, the corner bearing is particularly simple in design if the guide has an elongated hole in one component of the support arm or the sash-side fitting and a guide pin in the other component of the sash-side fitting or the support arm that engages in the elongated hole. Compared to a guide rail, such an elongated hole requires a particularly small installation space and can be manufactured very cost-effectively.

[0009] According to another advantageous embodiment of the invention, the elongated hole can have particularly large dimensions if the elongated hole is arranged on the support arm and the guide pin on the sash-side fitting part. The large dimensions allow for a wide range of parallel opening of the sash.

[0010] According to another advantageous embodiment of the invention, the corner bearing can be used in existing fittings if the guide pin is arranged at one end of the elongated hole in the closed position and at the other end in the parallel position of the sash. With this design, the guide pin moves the support arm into the rotational position when the sash is moved.

[0011] According to another advantageous embodiment of the invention, the sash is additionally supported at a further point beyond the guide pin when a pivot bearing arranged at the free end of the control link is designed with the sash-side fitting part as a pivot bearing or tilt-and-turn bearing. This design results in particularly high stability for the sash support provided by the corner bearing. Furthermore, the corner bearing can be selectively used in either a pivot fitting or a tilt-and-turn fitting by appropriately designing the bearing.

[0012] According to another advantageous embodiment of the invention, the corner bearing enables a uniform circumferential distance of the sash from the frame if the dimensions of the control link and support arm are dimensioned such that a straight line connecting the pivot bearing at the free end of the control link and the guide pin is arranged in a closed position above a corner bearing angle of the frame-side fitting part and parallel to it in a parallel parking position.

[0013] According to another advantageous embodiment of the invention, the corner bearing is designed to be particularly simple in construction if the guide bolt has a head connected to the wing-side fitting part with a base pin projecting from the head and guided in the elongated hole.

[0014] According to another advantageous embodiment of the invention, the manufacture of the corner bearing is particularly cost-effective if the head of the guide pin has a wide head section and a comparatively narrow base section, and if the base pin projects from the base section. This design allows the base pin to be configured as a rivet pin.

[0015] According to another advantageous embodiment of the invention, the corner bearing is designed to have particularly low friction if the base part has a sliding layer or sliding disc on its side facing the base pin. The sliding layer or sliding disc thus supports the weight of the wing on the support arm. Corresponding projections and recesses between the sliding disc and the guide pin prevent the sliding disc from rotating.

[0016] According to another advantageous embodiment of the invention, further simplifying the assembly of the corner bearing on the wing is achieved if the support arm is connected to a retaining body provided for attachment to the wing.

[0017] According to another advantageous embodiment of the invention, the retaining body is designed to be particularly simple in construction if the retaining body has a spring plate connected to the base pin and a locking element attached to the spring plate for locking with the wing.

[0018] According to another advantageous embodiment of the invention, the corner bearing is designed to be particularly simple in construction if the support arm is guided longitudinally displaceably in a longitudinal guide in the frame-side fitting part, if the support arm and control link are rotatably connected to each other via a link bearing, and if the control link has the rotary bearing for the wing-side fitting part at its free end.

[0019] The second problem mentioned, namely the design of a window or French door equipped with the corner bearing in such a way that ventilation is reliably prevented in the closed position, is solved according to the invention by the fact that the support arm and the guide are arranged completely in a rebate between the frame and the sash in the closed position.

[0020] This allows the window or French door to be fitted with a completely continuous, uninterrupted seal. The width of the support arm provides sufficient guidance for a large gap between the sash and the door when the door is held in the parallel position. This reliably prevents ventilation when the window is closed.

[0021] According to another advantageous embodiment of the invention, mounting the corner hinge on the window is particularly simple if the head of the guide bolt is arranged in a guide in the sash. With this design, the guide for the guide bolt and a sash hinge bracket for supporting the tilt bolt together form the sash-side hardware component.

[0022] The invention allows for numerous embodiments. To further illustrate its basic principle, one of these is shown in the drawing and described below. This shows in Fig. 1 A partial view of a window with a corner hinge, Fig. 2 enlarges the corner hinge of the window. Figure 1Fig. 3 a top view of the corner hinge in the closed position of the window, Fig. 4 a top view of the corner hinge in the parallel opening position of the window, Fig. 5 a top view of the corner hinge in the middle rotation position of the window, Fig. 6 greatly enlarged a guide bolt of the corner hinge Figure 1 .

[0023] Figure 1Figure 1 shows a window with a sash 2 that pivots against a frame 1 and with a corner hinge 3. The sash 2 is in a pivoted position away from the frame 1. When the sash 2 is closed, the corner hinge 3 is arranged in a rebate between the frame 1 and the sash 2 below a sash overlap 4, thus providing concealed support for the sash 2. Preferably, the window has a locking rod (not shown) for locking the sash 2 in a closed position, where the sash 2 lies within the frame 1, and in a parallel position, where the plane of the sash 2 is substantially parallel to the frame 1. Such a locking rod is described, for example, in EP 1 422 372 A1, and reference is made to that document for its disclosure.

[0024] Figure 2 shows enlarged corner bearing 3 from Figure 1with a frame-side fitting part 5 and a sash-side fitting part 6. The frame-side fitting part 5 has a clamping plate 7 for fastening to the frame 1 and a corner bearing bracket 9 connected to the clamping plate 7 via an adjustment device 8. The sash-side fitting part 6 has a sash bearing bracket 10 for mounting on the sash 2 and a locking plate 11 attached thereto. The fitting parts 5 and 6 are connected to each other via a linkage assembly 12.

[0025] The linkage assembly 12 has a control link 13 and a support arm 14, which are connected to each other via a common link bearing 15. The support arm 14 is guided longitudinally displaceably and pivotably in a longitudinal guide 16 in the frame-side fitting part 5. The control link 13 has a pivot bearing 17, 18 in both the frame-side fitting part 5 and the sash-side fitting part 6. The pivot bearing 18 on the sash-side fitting part 6 has an adjustment device 19 for adjusting the height of the sash bearing angle 10 relative to the control link 13. In the embodiment for a tilt-and-turn fitting, the pivot bearing 18 of the control link 13 on the sash-side fitting part 6 can be designed as a tilt-and-turn bearing.

[0026] The support arm 14 has a guide 20 at its end facing away from the frame-side fitting 5 for a guide bolt 21 arranged in the sash 2. The guide 20 is designed as an elongated hole 22 and is arranged essentially transversely to the longest extent of the support arm 14. The guide bolt 21 penetrates the elongated hole 22 with a Figure 6 The support arm 14 has a base pin 23 and a head 24 which, in the assembled state, is held in a guide groove (not shown) of the wing 2. Furthermore, a retaining element 25 is attached to the free end of the support arm 14. The retaining element 25 has a spring plate 26 connected to the support arm 14 and a locking element 27 attached to the spring plate 26 for locking it to the wing 2.

[0027] Figure 3 The corner bearing 3 is shown in a top view in the closed position, in which the wing 2 is... Figure 1The sash lies within frame 1 and can be locked via the connecting rod fitting (not shown). A plane of the sash 2, perpendicular to the plane of the drawing, passes through the axes of the pivot bearing 18 of the control link 13 on the sash-side fitting part 6 and of the guide bolt 21, and is shown with a dashed line in the drawing. This longitudinal axis lies above a straight line formed by the pivot axes of the link assembly 12 in the frame-side fitting part 5. The axis of the guide bolt 21 is located here at one end of the guide 20 formed by the elongated hole 22 in the support arm 14.

[0028] Figure 4 Figure 3 shows the corner bearing 3 in a top view in the parallel position. It can be seen that the line formed by the axes of the pivot bearing on the sash-side fitting part 6 and the guide pin 21 is slightly offset from the line formed by the pivot axes of the link assembly 12 in the frame-side fitting part 5. These lines are in Figure 4 The line is shown with a dashed line. The axis of the guide pin 21 is located here in comparison to... Figure 3 at the other end of the elongated hole 22. The movement and locking of the wing 2 relative to the frame 1 is effected, for example, by the connecting rod fitting described above.

[0029] Figure 5 Figure 1 shows the corner hinge 3 in a top view in its middle pivot position, in which the sash 2 is pivoted a short distance away from the frame 1. The bearing of the control link 13 on the frame-side fitting 5 is located here close to the end of the longitudinal guide 16, so that the distance between the bearings of the control link 13 and the support arm 14 is shorter than in the closed position. The straight line formed by the axes of the pivot bearing 18 of the sash-side fitting 6 and the guide pin 21 is shown in Figure 5 shown with a dash.

[0030] Figure 6Figure 1 shows an enlarged perspective view of the guide pin 21 of the corner bearing 3. The in Figure 2 The aforementioned base pin 23 is designed as a rivet pin and, in the assembled state, penetrates the elongated hole of the 22 support arm 14. The base pin 23 is riveted to the spring plate 26. The head 24 of the guide bolt 21 has a head section 29 arranged on a base part 28 and serves to guide it into a guide groove of the wing 2. On the side facing the base pin 23, the head 24 has a sliding disc 30.
