Description

Background of the invention

[0001] The invention relates to a window or a door with a frame and a tiltable and pivotable sash.

[0002] Every tilt-and-turn sash requires at least two bearing points on the underside of the sash to enable tilting around a tilt axis. A bearing point is usually a fixed bearing, i.e., a corner bearing, which, in addition to the lower pivot bearing (vertical axis), also enables the tilt bearing (horizontal axis) of the sash. This corner bearing is located below the scissor-arm bearing, which forms the upper pivot bearing. The second tilt bearing point on a tilt-and-turn sash is provided by a floating bearing. This floating bearing is available in various designs. A simple form of the floating bearing is described here.

[0003] DE 1 003 084 B discloses a tiltable and turn-openable window with a support plate that can be moved by a drive rod bolt to engage around a support roller.

[0004] DE 1 708 312 A1 discloses a tilting axis bearing in a slotted hole.

[0005] DE 2 243 916 A1 discloses a tilt-lock latch with a latch pocket on the frame into which a sash-side latch can be inserted during tilting. Other tilt-lock latch fittings equipped with a corresponding pocket are known from DE 2 255 042 A1 and DE 7 149 173 U.

[0006] DE 6 926 148 U discloses a fitting for tilt-and-turn windows in which a sash-side pin engages behind a locking piece mounted on the horizontal stile of a window frame in the tilt position.

[0007] From DE 10 2006 035 398 A1 a tilting bearing with a probe head is known, which is supported on the upper side of the horizontal beam of a window frame.

[0008] DE 10 2008 007 095 A1 discloses a turn-tilt fitting with a holding element and a locking element, wherein both the holding element and the locking element are designed like stud bolts.

[0009] DE 10 2008 021 047 A1 discloses another tilt-and-turn fitting that features a first locking piece on the horizontal stile of a frame and a second locking piece on the vertical stile of the frame. The locking pieces can be of identical design.

[0010] DE 10 2012 218 887 A1 and DE 201 14 422 U1 each disclose a locking piece with a slotted guide.

[0011] DE 27 22 692 A1 discloses an asymmetrically designed locking piece designed to effectively prevent a sash from being lifted out when tilted. DE 75 28 905 U discloses a tilt-and-turn fitting with a pivot pin that, in the tilt position, engages a recess in a fitting that can be connected to the frame.

[0012] From DE 200 04 941 U1 a turn-tilt fitting has become known in which a tilt pin bearing and a tilt pin interact in such a way that when the fitting is adjusted from the turn to the tilt position, the corner of a sash having the tilt pin is displaced in the opening direction with respect to a frame.

[0013] DE 26 48 735 A1 discloses a tilt-turn fitting, which tilt-turn fitting comprises: a striker arranged on a vertical frame member, a drive rod on the sash which is movable in its longitudinal direction, the drive rod having a pin which engages behind the striker in the closed position and engages behind it in the tilted position to form a joint. Object of the invention

[0014] In contrast, it is the object of the invention to provide a window or a door with a structurally simple tilt and turn fitting that enables a tension-free tilting of a sash. Description of the invention

[0015] This object is achieved according to the invention by a window or a door according to patent claim 1. The dependent patent claims represent preferred developments.

[0016] The object of the invention is thus achieved by a window or door with a frame, a tiltable and pivot-opening sash, a striker arranged on a vertical stile of the frame, and a drive rod with a pin that can engage behind the striker to form a hinge for tilting. The center of the pin, in the tilt position, has a distance of between 4 mm and 29 mm from the top of the rebate of the frame. This places the pin approximately at the height of a horizontal corner bearing axis, so that when the sash is tilted, high contact pressure from a sash overhang on the frame can be avoided.

[0017] The pivot engages behind the locking piece horizontally. The locking piece serves as a tilting anchor for the pivot.

[0018] The center of the pin in the lowest position, when the sash is in contact with the frame, preferably has a minimum distance of 4 mm, especially 8 mm. Alternatively or additionally, the center of the pin in the lowest position, when the sash is in contact with the frame, has a maximum distance of 15 mm from the top of the frame's rebate. The pin (bolt) is therefore in a particularly low position in its lowest position.

[0019] The pivot can preferably be moved by the drive rod (push rod) with a linear movement in one direction from the closed position into the turn-open position and from the turn-open position into the tilt position. In this embodiment of the invention, the sash has a turn-tilt standard closing sequence. In this turn-tilt standard closing sequence, the lowest position of the pivot corresponds to the tilt position. The center of the pivot preferably has a horizontal distance of 9 mm or 13 mm from the front of the frame. In the case of a horizontal distance of 9 mm from the front of the frame, the maximum distance from the center of the pivot to the top of the frame rebate is preferably 12 mm.

[0020] In an alternative embodiment of the invention, the sash has a tilt-first closing sequence. In this tilt-first closing sequence, the lowest position of the pivot corresponds to the turn-open position. The pivot can be moved by the drive rod with a linear movement in one direction: from the closed position to the tilt position, and from the tilt position to the turn-open position. In this case, the center of the pivot preferably has a horizontal distance of 13 mm from the front of the frame.

[0021] The rebate area refers in particular to the inner circumferential area between the frame and the sash frame.

[0022] The top of the frame's rebate refers in particular to the highest point of the frame in the rebate area - apart from any seal that may be present.

[0023] The terms "top," "bottom," "inside," "outside," etc., refer to the installed position of the window or door. The terms "closed position," "open-and-turn position," "gap ventilation position," and "tilt position" refer to both the positions of the pivot on the striker and the positions of the sash and the window or door.

[0024] According to the invention, the drive rod and / or the pin protrudes downwards over the underside of the rebate of the sash when the sash is in contact with the frame in the tilt position.

[0025] The underside of the sash's rebate refers specifically to the lowest point of the sash frame in the rebate area—apart from any seal. The underside of the sash's rebate is preferably located adjacent to the hardware groove.

[0026] The sash can have a handle and a gear to convert a pivoting movement of the handle into a linear movement of the drive rod. The drive rod is preferably located on the gear side of the sash.

[0027] Alternatively or additionally, the window or door may have an electric drive to move the drive rod.

[0028] In a further preferred embodiment of the invention, the locking piece can have a first contact web, which the pin engages behind in the tilted position. This allows for a particularly simple design of the locking piece.

[0029] The first support rib can be tapered upwards, with the pin engaging behind the first support rib at the tapered point in the gap ventilation position. In the gap ventilation position, the wall of the support rib is partially recessed outwards. This allows a gap ventilation position for the window or door to be provided in a particularly simple design. The higher the pin is moved vertically, the more play the sash has outwards away from the frame side. Furthermore, the provision of the gap ventilation position prevents the sash from being lifted out in the tilt position.

[0030] Preferably, in the case of the turn-tilt standard closing sequence, the pin can be moved successively into the following positions by the drive rod: closed position, turn-open position, gap ventilation position, tilt position.

[0031] In addition to the first contact rib, the striker can have a second contact rib, which the pin engages behind in the closed position. The striker can have a through-hole between the first contact rib and the second contact rib, through which the pin can pass the striker in the open, pivoted position. The striker can thus be designed in a butterfly shape. This further simplifies the design and manufacture of the striker.

[0032] The locking piece can be used for left-hand and right-hand stop if the locking piece is mirror-symmetrical, in particular mirror-symmetrical to a central plane running perpendicular to its longitudinal axis.

[0033] Further preferably, the locking piece is designed without a slot and / or as a single piece. Due to the slot-free design, the locking piece is open on one long side and is only engaged by the pin on the opposite long side. This makes the locking piece particularly easy to manufacture.

[0034] The window or door can have an angled corner connector for attaching a center post. The corner connector can extend beyond the fiberglass edge. To prevent the corner connector from colliding with the striker in this case, the striker is preferably designed to be particularly narrow. The width of the striker is particularly preferably less than 18 mm, in particular less than 17 mm, and preferably less than 16 mm. This measure also makes the striker particularly material-efficient.

[0035] The pin can be designed in the form of a mushroom-head pin, and the locking piece can have a rear handle that can be engaged behind the mushroom head. This makes the window or door particularly burglar-proof.

[0036] In a further embodiment of the invention, the pin can be mounted eccentrically on the drive rod, allowing it to rotate. This allows the contact pressure of the sash against the frame to be adjusted in the closed position.

[0037] Alternatively or additionally, the pin can be riveted to the drive rod to enable a particularly simple structural attachment of the pin to the drive rod.

[0038] Preferably, the pin is cylindrical.

[0039] The pin can be arranged in a T-shape on the drive rod. This means the pin is positioned straight on the drive rod, does not form a Z-shape with the drive rod, and can therefore absorb particularly high forces.

[0040] The window or door may have a mounting bracket located at the sash corner to guide the drive rod. The mounting bracket (connecting bracket / corner connector) enables the drive rod and pin to be securely guided in the sash corner.

[0041] The mounting bracket can be attached to a horizontal lower sash spar with a vertically aligned screw. This ensures that the screw is not covered by the connecting rod and is easily accessible for the installer.

[0042] Furthermore, the mounting bracket can have a support surface on the underside to support the sash against the top of a horizontal lower frame stile. In the event of the sash sagging or sinking, this allows the sash to rest on the frame during closing and reliably guide it into the closed position.

[0043] In order to be able to securely lock even wide sashes to the frame, the window or door can have a corner drive coupled to the drive rod and a center lock coupled to the corner drive.

[0044] The window or door may include a corner bearing with a horizontal pivot axis at a lower sash corner. The pivot axis is preferably immovable in the vertical direction.

[0045] In a further embodiment of the invention, a faceplate bar on the sash has a horizontal support for the run-up on the striker, in particular for the run-up on the upper side of the second contact web.

[0046] Further advantages of the invention will become apparent from the description and the drawings. The embodiments shown and described are not intended to be exhaustive, but rather serve as examples for describing the invention. Detailed description of the invention and drawing

The wing 14 is at least lockable, rotatable and tiltable (in Fig. 1the rotary opening position is shown).

[0049] To select these positions, the wing 14 has a drive rod 16 on which a pin 18 The pin 18 is designed to engage behind a locking piece 20 The striker 20 is attached to a vertical frame beam 22 The pin 18 is mounted on a vertical wing spar 24 arranged to be vertically movable.

[0050] The locking piece 20 and the pin 18 form a loose bearing 25. The wing 14 is fixed to the horizontally opposite wing corner by a corner bearing 26, here in the form of a fixed bearing, held on the frame 12.

[0051] The drive rod 16 is fixed to the wing 14 by a mounting bracket 28 The mounting bracket 28 is held by a vertical screw 30 on a horizontal wing spar 32The mounting bracket 28 can have a bottom run-up surface 33 for support on the top side of a horizontal lower frame beam 34 have.

[0052] Fig. 2 shows window 10 in the tilt position. Fig. 2 It can be seen that the corner bearing 26 has a horizontal corner bearing axis 35 The horizontal corner bearing axis 35 is vertically offset from the tilt axis of the pin 18 in the tilt position. This creates stresses in the sash 14 (see Fig. 11 ), which are, however, significantly reduced according to the invention.

[0053] Fig. 3 shows window 10 according to Fig. 2 supplemented by a corner deflection 36 and a center lock 38. This allows even large sash widths to be realized with the window 10 or door according to the invention. Corner guide 36 and center lock 38 are coupled to the drive rod 16.

[0054] Fig. 4 shows the drive rod 16 together with the mounting bracket 28 and the pin 18. The pin 18 protrudes straight from the drive rod 16.

[0058] Fig. 8 shows window 10 according to Fig. 7 in the gap ventilation position. In this position, the sash 14 can be opened slightly (by a few degrees). For this purpose, the first contact web 40 has a tapered 48 The wing 14 can be tilted until the pin 18 rests against the taper 48.

[0059] Fig. 9 Finally, the window 10 is shown with the fittings in the tilt position. In this position, the pin 18 engages behind the first contact bar 40 at a non-tapered point.

[0060] Fig. 10 shows window 10 according to Fig. 9 with a dimension. From Fig. 10 It can be seen that the center of the pin 18 in the tilted position is offset by the amount X above the top of the fold 50of the frame 12. Furthermore, the center of the tenon 18 is located by the dimension Y below the bottom of the fold 52 of the sash 14. The values ​​for X are preferably between 4 mm and 15 mm, in particular between 8 mm and 15 mm. The values ​​for Y are preferably between 4 mm and 3 mm. The center of the tenon 18 is thus located significantly below the rebate underside 52. This enables a largely stress-free tilting of the sash 14 and a pressing of a sash overlap 54 on the frame 12 when tilting the sash 14 is largely prevented.

[0061] The center of the pin 18 is Z horizontally offset from the front of the frame 12. In the present embodiment with standard turn-tilt closing sequence, dimension Z is preferably 9 mm or 13 mm.

[0062] Fig. 11 shows the window 10 in the tilt position, whereby Fig. 11It is evident that, due to the first contact web 40 projecting far upwards, the pin 18 is not lifted above the first contact web 40. Therefore, even with a "sweeping tilt," the wing is not lifted.
