Corner bearing with a chamfered and eccentric support bolt

Abstract

The invention relates in particular to a corner hinge (16) with a frame part (18) and a sash part (20) that is pivotable horizontally relative to the frame part (18). The sash part (20) is supported on a support bolt (34). The support bolt (34) can be attached, in particular in a rotationally fixed manner, at its lower end to a support bracket (26) of a bracket assembly (24). At its upper end, the support bolt (34) is preferably formed eccentrically to its lower end above the support bracket (34) and has a chamfered contour (46). The eccentric design of the support bolt (34) with respect to its longitudinal axis (40) prevents the sash part (20) from tilting in the open position of the corner hinge (16), even under high loads on the sash part (20). The chamfered contour (46) allows the sash part (20) to tilt in the closed position of the corner hinge (16).The support bolt (34) is preferably received in an opening (38), in particular in the form of an axial through-opening, of the sash part (20), which may have a constriction (54) in the lower region of the support bolt (34), i.e., a narrowing of the radial width of the opening (38). The invention further relates to a window (10) or a door with such a corner hinge (16).

Description

Background of the invention

[0001] The invention relates to a corner bearing for connecting a sash of a window or door to a fixed frame of the window or door, wherein the corner bearing comprises the following: A) a frame part which can be attached to the fixed frame; B) a sash part which can be attached to the sash and which can be pivoted relative to the frame part in order to enable the sash to be pivoted from a closed position of the corner bearing into an open position relative to the frame part; C) a support bolt arranged rotatably in an opening in the wing part.

[0002] EP 0 803 625 B1 discloses such a generic corner hinge with a supporting bolt supported at the bottom by a ball head. The ball head enables the tilt opening of a sash connected to this corner hinge.

[0003] Various methods are known for using a corner bearing to connect a pivot-opening and tilt-opening sash to a fixed frame. The corner bearing can be designed – visually appealing – as a concealed corner bearing that is largely invisible when the sash is closed. Such a corner bearing is known, for example, from the applicant's EP 2 385 204 A2.

[0004] FR 2 881 167 A1 discloses a corner bearing with several adjustment options.

[0005] The applicant is also aware of a competitor's product in which a support bolt is firmly connected to a tab of a corner bearing, the tab being tiltable to enable a tilting function of a sash of a window or door.

[0006] Finally, the applicant is aware of a competitor's product in which a support bolt is pivotably mounted on a tab of a corner bearing in order to implement a tilting function.

[0007] The problem with the known corner bearings, however, is that either there is no possibility of tilting a sash or the corner bearing is not stable enough to support the sash during continuous operation without it sinking. Object of the invention

[0008] The object of the invention is therefore to provide a corner bearing that both provides a tilting option and is particularly stable. It is also an object of the invention to provide a window or door with such a corner bearing. Description of the invention

[0009] This object is achieved according to the invention by a corner bearing according to claim 1 and a window or a door according to claim 9. The dependent claims represent preferred developments.

[0010] The object of the invention is thus achieved by a corner bearing as described above, wherein D) the support bolt has, on a radial side of its free end, an axially extending contour at an acute angle to the longitudinal axis of the support bolt, wherein the inner wall of the opening in the closed position is at least partially spaced from this contour in order to enable tilting of the sash part relative to the frame part; and E) the support bolt is designed to be radially eccentric to its longitudinal axis in sections when viewed in the direction of its longitudinal axis.

[0011] The partially eccentric design of the support bolt counteracts the tilting of the open sash (in the open position of the corner hinge). At the same time, the angled contour of the support bolt allows a tilting movement of the sash section (and thus the sash) in the closed position of the corner hinge.

[0012] In this application, "closed position," "open position," and "tilt position" always refer to the corner hinge, the sash (if any) located on the sash part of the corner hinge, and the window or door with the corner hinge. The corner hinge can be moved from the closed position to the tilted position and back to the closed position.

[0013] Spatial designations such as “top”, “bottom”, “horizontal” and the like in the present application refer to the state of the corner bearing mounted in a window or door.

[0014] The bevel of the contour of the support bolt preferably has an angle between 1° and 80°, in particular between 2° and 60°, particularly preferably between 5° and 30°, to the longitudinal axis of the support bolt.

[0015] Preferably, the inner wall of the opening is also eccentrically designed, particularly adapted to the eccentric design of the support bolt. This ensures a particularly smooth opening movement while reliably supporting and guiding the support bolt on the inner wall of the opening.

[0016] Furthermore, the opening can have a radial constriction near its lower end. This constriction allows for a large tilt angle of the support bolt in the opening as well as good guidance of the support bolt.

[0017] The support bolt can be essentially mushroom-shaped. The support bolt can have an axially elongated head section at its free end that is wider and beveled than its lower end.

[0018] In a particularly preferred embodiment of the invention, the corner bearing has a bracket arrangement with a support bracket and a first control bracket. The bracket arrangement is provided for guiding the pivoting and opening movement of the sash part. The support bolt can be arranged on the support bracket.

[0019] The support bracket can be rotatably mounted on the first control bracket. The first control bracket can be rotatably mounted on the frame part. The bracket arrangement can further comprise a second control bracket, which is rotatably mounted on the sash part and rotatably mounted on the first control bracket. Alternatively or additionally, the bracket arrangement can comprise a third control bracket, which is rotatably mounted on the support bracket and rotatably mounted on the frame part. The bracket arrangement enables a large opening angle of the sash part relative to the frame part in the open position of the corner bearing while efficiently distributing the sash load.

[0020] The sash part can have a stop projection which, in the closed position, strikes the tab arrangement and / or the frame part so that a defined closed position is achieved.

[0021] The support bolt is preferably arranged in a rotationally fixed manner. This significantly stabilizes the corner hinge and prevents sagging when transferring high sash loads. The support bolt is preferably attached to the support bracket in a rotationally fixed manner.

[0022] The sash part is preferably supported axially on the support bolt, either directly or indirectly, via a threaded pin screwed into the opening. The opening of the sash part can have an internal thread for screwing in the threaded pin. At least one buffer part can be provided between the threaded pin and the support bolt. The buffer part can be provided to reduce friction during the pivoting opening of the corner bearing.

[0023] The support bolt can rotate between 0° and 50° around its longitudinal axis when moving the corner hinge from the closed position to the open position. This allows for particularly secure guidance and good support from the support bolt throughout the entire opening movement. Preferably, the longitudinal bolt only rotates between 0° and 30°, especially between 0° and 20°, around its longitudinal axis.

[0024] To allow the sash to be opened as far as possible, the sash part can preferably be pivoted by more than 160° relative to the frame part, in particular around the longitudinal axis of the support bolt. The sash part can preferably be pivoted by more than 170°, in particular more than 180°, so that the opened sash (corner hinge in the open position) does not protrude into the room. The sash part can preferably be pivoted by a maximum of 330°, in particular a maximum of 300°, and particularly preferably a maximum of 270°, relative to the frame part.

[0025] The object of the invention is further achieved by a window or door with a fixed frame, a sash, and a corner bearing as described here, which is arranged between the fixed frame and the sash for pivoting and tilting the sash. The corner bearing is preferably arranged on the underside of the sash.

[0026] The corner bearing can be designed as a concealed corner bearing, which is largely, or even completely, concealed between the sash and the fixed frame in the closed position. This design of the window or door is particularly visually appealing, as the corner bearing is essentially invisible in the closed position.

[0027] Further advantages of the invention will become apparent from the description and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combination in any desired manner. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention.

[0028] Detailed description of the invention and drawing Fig. Figure 1a shows a plan view of part of a window with a fixed frame, a sash and a corner bearing for connecting the sash to the fixed frame, with the corner bearing and window in the closed position. Fig. 1b shows an enlarged top view of the corner bearing in the closed position according to Fig. 1a in unique position. Fig. 2 - 4 show the corner bearing according to Fig. 1b in an increasingly open position. Fig. 5a shows the window according to Fig. 1a in the open position. Fig. 5b shows the corner bearing in the open position according to Fig. 5a in enlarged unique position. Fig. 6 shows a sectional view of the corner bearing according to Fig. 1b, where the section runs through a supporting bolt of the corner bearing. Fig. 7 shows the sectional view according to Fig. 6, with the corner bearing in the tilt position. Fig. 8 shows the sectional view according to Fig. 6, whereby the corner bearing is in the open position according to Fig. 5b is located.

[0029] Fig. 1a shows a window 10 with a fixed frame 12 and a sash 14. The sash 14 is supported on the fixed frame 12 via a corner bearing 16. The corner bearing 16 is designed as a concealed corner bearing, so that it can be Fig. 1a is practically invisible.

[0030] Fig. 1b shows the corner bearing 16 without fixed frame 12 and sash 14 (see Fig. 1a).

[0031] Fig. 2 shows the corner bearing 16 in a partially open position. Fig. 2 it can be seen that the corner bearing 16 is connected to the fixed frame 12 (see Fig. 1a) connectable frame part 18 and a wing 14 (see Fig. 1a) connectable sash part 20. The sash part 20 has a stop projection 22 which prevents the movement of the corner bearing 16 (see Fig. 1b) limited to the closed position.

[0032] Between the frame part 18 and the wing part 20, a tab arrangement 24 is provided, which holds the wing part 20 during the opening movement from the closed position according to Fig. 1b into the open position according to Fig. 5b from the fixed frame 12 (see Fig. 1a) spaced and pivoted.

[0033] The tab assembly 24 preferably includes a support tab 26, a first control tab 28, and a second control tab 30. The tab assembly 24 may further include a slot 32. The first control tab 28 may be rotatably mounted on the frame member 18. The support tab 26 may be rotatably mounted on the first control tab 28. The support tab 26 may further be guided at one end in the slot 32. Alternatively, the support tab 26 may be guided on the frame member 18 via a third control tab (not shown).

[0034] The second control tab 30 can be arranged with a rotatable connection between the first control tab 28 and the wing part 20.

[0035] Fig. 3 shows the corner bearing 16 in a further opened state. Fig. The position shown in Figure 3 corresponds to an opening angle of 90°. In this position, the wing 14 (see Fig. 1a) vertically from the fixed frame 12 (see Fig. 1a) protruding into the room.

[0036] Fig. 4 shows the corner bearing 16 in an even wider open state. Fig. 4 it is evident that the wing part 20 in this state has already pivoted far beyond the frame part 18. A wing 14 (see Fig. 1a) with a high sash weight already exerts a considerable torque on the frame part 18 and a high bending moment on the tabs 26, 28 in this position.

[0037] Fig. 5a shows the window 10 with the corner bearing 16 in the opening position, with the sash 14 opened by 180° to the fixed frame 12.

[0038] Fig. 5b shows the corresponding corner bearing 16 in isolation. In the opening position shown, the support bracket 26 rests partially on the first control bracket 28, so that a high weight of the sash 14 (see Fig. 5a) reliably into the frame 12 (see Fig. 5a) can be removed.

[0039] Fig. 6 shows the cut corner bearing 16 in the closed position (cf. Fig. 1b). From Fig. 6 shows that the corner bearing 16 has a support pin 34 that is non-rotatably mounted on the support bracket 26. The support pin 34 has a projection 36 that is inserted into the support bracket 26. The projection 36 has a flattened portion on the side to ensure the correct installation position. The support pin 34 is received in an opening 38 in the sash part 20.

[0040] The support bolt 34 has a longitudinal axis 40 which runs centrally, in particular radially rotationally symmetrically, through the support bolt 34 in the region of its fixed end, but outside the projection 36. In order to prevent the support bracket 26 from tipping over in the open position of the corner bearing 16 (see Fig. 8), the free end of the support bolt 34 has a free longitudinal axis 42 offset from the longitudinal axis 40, which extends centrally, in particular radially rotationally symmetrically, through the free end of the support bolt 34. The free end of the support bolt 34 is formed eccentrically to its longitudinal axis 40, in particular due to the offset of the free longitudinal axis 42 from the longitudinal axis 40.

[0041] In the present case, an inner wall 44 of the opening 38 in the region of the free end of the support bolt 34 is also eccentric to the inner wall 44 in the region of the fastened end but outside the projection 36 of the support bolt 34.

[0042] Fig. 7 shows the corner bearing 16 in the tilted position. Fig. 7 shows that the free end of the support bolt 34 has a contour 46 that is beveled relative to its longitudinal axis 40 to enable the tilting of the wing part 20 relative to the support bracket 26. The contour 46 has an acute angle 48.

[0043] Fig. 8 shows the corner bearing 16 in the open position (see also Fig. 5b). From Fig. 8 shows that tilting of the wing part 20 is prevented by the support pin 34, on the one hand, in the region of its free end (particularly at reference numeral 50) against the inner wall 44 and, on the other hand, in the region of its fixed end (particularly at reference numeral 52), against a constriction 54 of the opening 38 (radial with respect to the longitudinal axis 40 of the support pin 34). The eccentric design of the free end of the support pin 34 particularly effectively prevents the tilting of the wing part 20.

[0044] The support of the wing part 20 on the support bolt 34 (axial with respect to the longitudinal axis 40 of the support bolt 34) is preferably provided by a threaded pin 56 screwed into the opening 38. A buffer part 58 can be provided between the threaded pin 56 and the support bolt 34. Both the threaded pin 56 and the buffer part 58 are in Fig. 8 is shown only schematically.

[0045] Taking a summary of all the figures in the drawing, the invention relates in particular to a corner bearing 16 with a frame part 18 and a sash part 20 that can be pivoted horizontally relative to the frame part 18. The sash part 20 is supported on a support bolt 34. The support bolt 34 can be fastened, in particular in a rotationally fixed manner, at its lower end to a support bracket 26 of a bracket arrangement 24. At its upper end, the support bolt 34 is preferably eccentric to its lower end above the support bracket 34 and has a beveled contour 46. The eccentric design of the support bolt 34 with respect to its longitudinal axis 40 prevents the sash part 20 from tipping in the open position of the corner bearing 16, even under high loads on the sash part 20. The beveled contour 46 enables the sash part 20 to tilt in the closed position of the corner bearing 16.The support bolt 34 is preferably received in an opening 38, in particular in the form of an axial through-opening, of the sash part 20, which may have a constriction 54 in the lower region of the support bolt 34, i.e., a narrowing of the radial width of the opening 38.
