The invention relates to a window (10) or a door with a sash (14) that can be tilted and opened by rotation. A tilting axis of the sash (14) is realized at a sash corner by a horizontally extending pin (18) which, in the tilted position, engages behind a locking piece (20) on a vertical window frame part. When the sash (14) is in contact with the window frame (12), the pin (18) is only arranged between 4 mm and 29 mm above the rebate top side of the window frame (12) in order to achieve a stress-free tilting of the sash (14) and a strong pressing of a sash overlap on the Glare frame (12) to avoid.

Description

Background of the Invention

The invention relates to a window or a door with a window frame and a sash that can be tilted and opened by rotation.

Each turn-tilt sash requires at least 2 bearing points on the underside of the sash to enable tilting around a tilting axis. A bearing point is usually a fixed bearing, ie a corner bearing, which, in addition to the lower rotary bearing (vertical axis), also allows the sash to be tilted (horizontal or horizontal axis). This corner bearing sits below the scissor-stay bearing, which forms the overhead pivot bearing. The second tilt bearing point is solved by a floating bearing on a tilt and turn sash. This loose bearing is available in various designs. A simple form of the floating bearing is described here.

the DE 1 003 084 B discloses a window that can be tilted and rotated and has a support plate that can be displaced by a connecting rod bolt for gripping around a support roller.

From the DE 1 708 312 A1 a tilting axis bearing in a slot has become known.

the DE 2 243 916 A1 discloses a tilting latch lock with a latch pocket on the frame, into which a latch attachment on the wing side can dip when tilted. Other toggle bolt locking fittings with a corresponding pocket are from DE 2 255 042 A1 and the DE 7 149 173 U known.

the DE 6 926 148 U discloses a fitting for turn-tilt windows, in which a sash-side pin in the tilted position engages behind a locking piece mounted on the horizontal bar of a window frame.

From the DE 10 2006 035 398 A1 a tilting bearing with a probe head has become known, which is supported on the top of the horizontal beam of a frame.

the DE 10 2008 007 095 A1 discloses a tilt and turn fitting with a holding element and a locking element, both the holding element and the locking element being designed like studs.

From the DE 10 2008 021 047 A1 another tilt and turn fitting has become known, which has a first locking piece on the horizontal bar of a frame and a second locking piece on the vertical bar of the frame. The closing pieces can be of the same design.

the DE 10 2012 218 887 A1 and DE 201 14 422 U1 each disclose a closing piece with a link guide.

From the DE 27 22 692 A1 an asymmetrically designed closing piece has become known, which is intended to effectively prevent a wing from being lifted out when it is tilted.

the DE 75 28 905 U discloses a tilt and turn fitting with a joint-forming pin which, in the tilted position, engages in a recess of a fitting which can be connected to the window frame.

From the DE 200 04 941 U1 a tilt and turn fitting has become known in which a pivot bearing and a pivot pin interact in such a way that when the fitting is adjusted from the pivot position to the tilt position, the corner of a wing containing the pivot pin is displaced in the opening direction with respect to a window frame.

object of the invention

In contrast, the object of the invention is to provide a window or a door with a structurally simple tilt and turn fitting that allows a sash to be tilted without tension.

Description of the invention

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

The object according to the invention is thus achieved by a window or a door with a window frame, a tiltable and rotatably openable sash, a locking piece arranged on a vertical beam of the window frame and a connecting rod with a pin which can engage behind the locking piece to form a joint for tilting, the center of the pin in the tilted position has a distance of between 4mm and 29mm to the rebate top side of the window frame. As a result, the pin is located approximately at the level of a horizontal corner bearing axis, so that when the sash is tilted, a high contact pressure of a sash overhang on the frame can be avoided.

The pin engages behind the locking piece in the horizontal direction. The closing piece serves as a tipping anchor for the pin.

The center of the pin in the lowest position preferably has a minimum spacing of 4 mm, in particular 8 mm, when the sash is in contact with the window frame. As an alternative or in addition to this, the center of the pin in the lowest position when the sash is in contact with the window frame has a maximum distance of 15mm to the rebate top side of the window frame. The pin (bolt) is in its lowest position as a result at a particularly low position.

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

In an alternative embodiment of the invention, the wing has a tilt-first closure sequence. In this tilt-first closing sequence, the bottom position of the pin corresponds to the pivot open position. The pin can be moved by the connecting rod with a linear movement in one direction after the closed position into the tilted position and after the tilted position into the rotary opening position. In this case, the center of the pin preferably has a horizontal distance of 13 mm to the front of the window frame.

The rebate area is understood in particular as the inner peripheral area between the frame and the sash.

The upper side of the rebate of the window frame is understood to mean, in particular, the highest point of the window frame in the rebate area - apart from any seal that may be present.

The information "top", "bottom", "inside", "outside" etc. refers to the assembled state of the window or door. The terms "closed position", "opening position", "gap ventilation position" and "tilt position" refer both to the positions of the pin on the closing piece and to the positions of the sash and the window or door.

Preferably, the connecting rod and/or the pin in the tilted position protrudes downwards over the rebate underside of the sash when the sash is in contact with the window frame.

The underside of the rebate of the sash is understood to be the lowest point of the sash frame in the rebate area - apart from any seal that may be present. The underside of the fold of the wing is preferably located adjacent to the fitting part groove.

The wing may include a handle and gearing to translate pivotal movement of the handle into linear movement of the connecting rod. The connecting rod is preferably provided on the wing on the transmission side.

Alternatively or additionally, the window or the door can have an electric drive for moving the connecting rod.

In a further preferred embodiment of the invention, the closing piece can have a first contact web, which the pin engages behind in the tilted position. This enables a structurally particularly simple design of the closing piece.

The first contact web can be tapered upwards, with the pin engaging behind the first contact web in the gap ventilation position at the tapered point. In the gap ventilation position, the wall of the contact bar is partially outwards reset. As a result, a gap ventilation position for the window or the door can be provided in a structurally particularly simple manner. The higher the pin is moved in the vertical direction, the more play the sash has outwards away from the frame side. In addition, the provision of the gap ventilation position prevents the sash from being lifted out in the tilted position.

In the case of the turn-tilt standard closing sequence, the pin can preferably be moved one after the other by the drive rod into the following positions: closed position, rotating-open position, gap ventilation position, tilt position.

In addition to the first contact web, the closing piece can have a second contact web, which the pin engages behind in the closed position. The closing piece can have a through-opening between the first contact bar and the second contact bar, through which the pin can pass the closing piece in the rotary open position. The closing piece can therefore be designed in the shape of a butterfly. This further simplifies the design and manufacture of the closing piece.

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

More preferably, the closing piece is formed without a link and/or in one piece (in one piece). Due to the link-free design, the closing piece is designed to be open on one long side and the pin only engages behind it on the opposite long side. The closing piece is particularly easy to manufacture as a result.

The window or door may have an angled corner connector for attachment of a mullion. The corner connector can protrude beyond the glass fiber edge. In this case, a collision of the corner connector with the locking piece to avoid, the closing piece is preferably particularly narrow. The width of the closing piece is particularly preferably less than 18 mm, in particular less than 17 mm, preferably less than 16 mm. The closing piece is also designed to be particularly material-saving as a result of this measure.

The pin can be designed in the form of a mushroom head pin and the closing piece can have a catch behind which the mushroom head can be gripped. This allows the window or door to be made particularly burglar-proof.

In a further embodiment of the invention, the pin can be arranged eccentrically rotatable on the connecting rod. As a result, the contact pressure of the sash on the frame in the closed position can be adjusted.

Alternatively or in addition to this, the pin can be riveted to the connecting rod in order to enable the pin to be fastened to the connecting rod in a structurally particularly simple manner.

Preferably, the pin is cylindrical.

The pin can be arranged in a T-shape on the connecting rod. The pin is thus arranged straight on the connecting rod, does not form a Z-shape with the connecting rod and can therefore absorb particularly large forces.

The window or door can have a mounting bracket arranged at the sash corner for guiding the connecting rod. The mounting bracket (connecting bracket / corner connector) enables the drive rod and the pin to be guided securely in the sash corner.

The mounting bracket may be attached to a horizontal lower wing spar by a vertically oriented screw. As a result, the screw is not covered by the drive rod and is easily accessible for a fitter.

Furthermore, the mounting bracket can have an underside run-up surface for supporting the sash on the upper side of a horizontal lower frame member. In the event of sagging or lowering of the sash, the sash can be supported on the window frame when closing and can be guided reliably into the closed position.

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

The window or door can include a corner bearing with a horizontal corner bearing axis at a lower sash corner. The corner bearing axis is preferably designed to be immovable in the vertical direction.

In a further embodiment of the invention, a faceplate on the sash has a horizontal support to run up on the closing piece, in particular to run up on the upper side of the second contact bar.

Further advantages of the invention result from the description and the drawing. Likewise, the features mentioned above and those detailed below can be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

1 shows a window 10 with a frame (fixed frame) 12 and a sash 14, the sash 14 in 1 for reasons of clarity is largely hidden and only indicated with dashed lines (see also 11 ). The wing 14 is at least closable, rotatable and tiltable (in 1 the rotary opening position is shown).

To select these positions, the wing 14 has a connecting rod 16 on which a pin 18 is arranged. The pin 18 is provided for engaging a locking piece 20 from behind. The closing piece 20 is arranged on a vertical frame member 22 . The pin 18 is arranged to be vertically movable on a vertical wing spar 24 .

The closing piece 20 and the pin 18 form a movable bearing 25. The wing 14 is held on the horizontally opposite wing corner by a corner bearing 26, here in the form of a fixed bearing, on the frame 12.

The connecting rod 16 is held on the wing 14 by a mounting bracket 28 . The mounting bracket 28 is attached to a horizontal wing spar 32 by a vertical screw 30 . The mounting bracket 28 can have a ramp surface 33 on the underside for support on an upper side of a horizontal lower frame member 34 .

2 shows the window 10 in the tilted position. Out of 2 it can be seen that the corner bearing 26 has a horizontal corner bearing axis 35 . The horizontal corner bearing axis 35 is offset vertically to the tilting axis of the pin 18 in the tilted position. This creates tension in the wing 14 (see 11 ), which are significantly reduced according to the invention.

3 shows the window 10 according to FIG 2 supplemented by a corner drive 36 and a center lock 38. As a result, large leaf widths can also be realized with the window 10 according to the invention or the door according to the invention. Corner drive 36 and center lock 38 are coupled to the drive rod 16 for movement.

4 shows the drive rod 16 together with the mounting bracket 28 and the pin 18. The pin 18 is straight from the drive rod 16 from.

figure 5 shows the locking piece 20. Off figure 5 it can be seen that the closing piece 20 is symmetrical. It has a first contact bar 40 and a second contact bar 42 . Between the contact webs 40, 42 there is a through-hole 44 for fastening the closing piece 20 by means of a screw (not shown).

6 shows the window 10 in the closed position. In this position, the pin 18 engages behind the second contact web 42.

7 shows the window 10 according to FIG 6 in the rotary opening position. In this position, the pin 18 can pass through a central passage opening 46 of the closing piece 20 . The through opening 46 extends in the width of the closing piece 20.

8 shows the window 10 according to FIG 7 in the gap ventilation position. In this position, the wing 14 can be opened slightly (by a few degrees). For this purpose, the first contact bar 40 has a taper 48 . The wing 14 can be tilted until the pin 18 abuts the taper 48 .

9 finally shows the window 10 with fittings in the tilted position. In this position, the pin 18 engages behind the first contact web 40 at an untapered point.

10 shows the window 10 according to FIG 9 with a dimension. Out of 10 it can be seen that the center of the pin 18 is in the tilted position by the dimension X above the rebate top 50 of the frame 12. Furthermore, the center of the pin 18 is located by the dimension Y below the fold underside 52 of the wing 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 -4mm and 3mm. The center of the pin 18 is therefore significantly below the fold underside 52 arranged. As a result, a largely stress-free tilting of the sash 14 is made possible and a pressing of a sash overlap 54 on the frame 12 when the sash 14 is tilted is largely prevented.

The center of the pin 18 is offset horizontally to the front of the frame 12 by the dimension Z. In the present exemplary embodiment with a turn-tilt standard closing sequence, the dimension Z is preferably 9mm or 13mm.

11 shows the window 10 in the tilted position, with off 11 it can be seen that due to the first contact bar 40 projecting far upwards, the pin 18 is not lifted out via the first contact bar 40 . As a result, the wing is not lifted even in the case of a "sweeping tilting".

12 Figure 12 shows a window 10 with a tilt-first closing sequence with a peg 18 on a sash 14 in the closed position. The pin 18 rests against a thickened section 56 of a closing piece 20 .

13 shows the window 10 with the pin 18 in the tilted position. Out of 13 it can be seen that the center of the pin 18 when the sash 14 is in contact with the frame 12 is offset upwards by the dimension X above the rebate top side 50 of the frame 12 . The dimension X is preferably 26.5 mm. The dimension Z is preferably 13mm.

14 shows the window 10 with the pin 18 in the tilted position. Out of 14 it can be seen that the pin 18 rests against a first contact web 40 of the closing piece 20 when the leaf 14 is tilted.

15 shows the window 10 with the pin 18 in the rotary open position. In this lowermost position of the pin 18, the pin 18 can pass through the closing piece 20, in particular the first contact web 40, preferably on the underside.

16 shows the locking piece 20. Off 16 it can be seen that the closing piece 20 is mirror-symmetrical to a central plane running perpendicular to its longitudinal axis is trained. The closing piece 20 is hereby suitable both for a left-hand stop and for a right-hand stop. Furthermore, the closing piece 20 is formed without a link and in one piece.

17 also shows the locking piece 20. Off 17 It can be seen that the closing piece 20 has through-holes 44a, 44b for fastening the closing piece by means of screws (not shown).

Taking all the figures of the drawing together, the invention relates in summary to a window 10 or a door with a sash 14 that can be tilted and rotated 20 engages behind on a vertical frame part. When the sash 14 rests against the frame 12, the pin 18 is only between 4 mm and 29 mm above the rebate top 50 of the frame 12 in order to achieve a stress-free tilting of the sash 14 and to avoid a strong pressing of a sash overlap 54 on the frame 12.
