Description

The invention relates to a tilt and turn fitting for a Window, door or the like with a gear, Folding tapes and locks.

Windows or doors, both around a vertical axis swung open (rotated) as well as around a horizontal axis can be tilted are well known. This Windows or doors have a tilt and turn fitting, which is driven by a handle. This is used for Gear, which is operated by the handle and with which the folding tapes are moved in the casement. The rotary handle usually has three positions, whereby one position represents the closed position which rotates the rotary handle by 90 ° into the rotary position can be. The window can then be turned in this position or the door is pivoted about the vertical axis and can be opened. If the wing is closed the Turned the handle by another 90 °, then there is the fitting in its tilted position, so that the wing turns around a horizontal axis can be tilted. The wing will usually from a pair of scissors, which on the Attacks the upper edge of the wing, held. It turned out to be disadvantageously found that in the tilted position of the Wing cannot take intermediate layers, i.e. only can be fully tilted until the Folding scissors limit the tilting movement.

The invention is therefore based on the object To provide turn-tilt fitting, with which the sash when Tilting can also take intermediate positions.

This object is achieved in that a turn-tilt fitting of the type mentioned There is a rotating fitting and a tilt fitting and that Gearbox is constructed in two parts and a drive for the Swivel fitting and a drive for the tilt fitting has, the rotary fitting and the tilt fitting are driven one after the other.

In the turn-tilt fitting according to the invention, the wing unlocked by means of the rotating fitting and the rotating position enables. For this, only the rotating fitting is driven, for which a separate drive is provided. Should the sash can be tilted, then the swivel fitting in its other end position with regard to the locking position brought in which the wing on the side with the fixed Frame is locked around which the wing is tilted shall be. The rotary fitting is in this End position, then the tilt fitting is driven and the Wing gradually from its closed position in the fixed frame brought into the tilt position. Each the further the tilt fitting is driven, the larger it becomes the opening angle of the tilted wing. With the invention Tilt & Turn hardware is now available depending on how far the tilt fitting is driven will tilt the wing more or less far. Located the tilt fitting in its opposite the Close position other end position, then the wing takes its fully tilted position.

It should be emphasized that the tilting of the wing does not go through the rotary fitting that drives the locks becomes. There is a separate one for tilting the wing Tilt fitting provided, which is independent of the rotating fitting is driven.

Preferably, the rotary fitting can be driven when the Tilt fitting takes its rest position and vice versa. It so the rotating fitting and the tilt fitting cannot be driven at the same time, but always one after the other, i.e. then one fitting can be driven when the other fitting is in its rest position occupies.

According to one embodiment, the transmission has one central slide, which is a first slide for the Swivel fitting and a second slide for the tilt fitting drives. The central slide is e.g. about one central drive, e.g. a twist grip, a crank or The like. Driven. By means of the central slide then the first slider in succession and then the second Slider moves over which the rotary fitting and then the Tilt fitting can be driven. The sliders have that essential advantage that they build relatively flat and therefore can be easily accommodated in the frame of the wing can.

According to one embodiment, the first and the second slider coupled to the central slider in such a way that only one of the two other sliders is moved. Coupling or Uncouple the two sliders from the central slider takes place by means of a clutch, which automatically the one Slider then couples when the other slider in the corresponding end position is located and uncoupled. Then the drive movement e.g. from the swivel fitting the tilt fitting or vice versa.

In another embodiment it is provided that the Gear can be driven by means of a crank. A crank has the main advantage that finer settings are possible, which in particular when tilting the wing of The advantage is that almost every intermediate position in this way between the completely closed and the completely tilted position of the wing can be adjusted can. It is also noted that the transmission is also motor-driven, so that the wing can be tilted remotely.

The transmission preferably has a gear transmission, in particular a differential gear, on. Differential gear are well known and they have the advantage that relatively high forces can be transmitted with them. The Lever arm of the crank can therefore be kept relatively short and it can still be relatively heavy wings tilted and closed again.

The connection of the swivel fitting and the tilt fitting to the gearbox is made by the fact that the rotary fitting has a first rack section and the tilt fitting one second rack section, which is part of the transmission are. The gearbox therefore grips directly over the Rack sections on the swivel fitting and on the tilt fitting on and relocated them as part of the wing. However, it is also noted here that either the swivel fitting or the tilt fitting are driven, in particular both fittings one after the other.

In a preferred embodiment, the drive for the turn-tilt fitting on and there are Rack sections next to each other or one above the other inside the case and are stacked by two lying gears driven, the two gears are motion-coupled. The two point Gears on part of their circumference teeth stand up sequentially engaged with the racks. Means of these two gears, in particular driven together be the one rack section brought from its one end position to the other end position, then the other rack section is driven and brought from its one end position to the other end position becomes. The turn-tilt fitting becomes part of this movement from its wing locking position to its Wing fully tilted position.

A further development provides that the two rack sections by means of a locking device can be locked with the housing of the turn-tilt fitting, that only one rack section can be driven by means of the transmission is. The locking device prevents both rack sections are moved. In particular becomes the non-driven rack section against unintentional Relocated secured. That way ensures that the rack sections then when the drive from one rack section to the other transferred, take their rest positions. This also applies to the slider mentioned above.

According to a preferred embodiment, the locking device a locking element on which is driven by a rack section and connects another rack section to the housing and vice versa. This locking element is always from a rack section driven when his Rest position or end position reached. Then the other rack section released so that its end position can leave, which then the other rack section is locked in the previously assumed end position. Only then will this locked rack section released again when the other rack section has returned to its end position and that Locking element releases.

As a locking element e.g. a bullet or a Serve cylinder roller that in openings of the rack sections intervenes. Since the ball or roller from Housing is fixed, that rack section fixed, in which the ball or the roller engages.

According to a preferred embodiment, this is achieved Locking element always in an unlocked position, if from a drive for the rotary fitting to another drive for the tilt fitting, or vice versa, is changed. Then the two are always there Fittings in their end positions, so that the two fittings not be driven at the same time.

The tilting fitting preferably has an opening flap, which is provided in the area of the transmission. About these Flap is the wing around the horizontal axis tilted the frame, the provided at the top Folding scissors are not required for this. she serves if necessary, only as a safeguard and guide for the wing.

Then turn it around a vertical axis can if the fitting is the position for the rotary position occupies, the free end of the tab is fixed in one Closing plate provided in the frame can be hooked on. The striker is made in two parts, one part of one Slider is formed, which opens the closing plate and closes. When the striker plate is open, the free end can the tab, in particular one provided at the free end Pin, hooked into the locking plate and fixed there become. The striking plate is always open when the Turning fitting takes its unlocked position and the Locks are opened so that the wing around the vertical axis can be rotated.

The tab is preferably detachably attached to the tilt fitting, so they're against a longer or shorter tab can be replaced, creating the maximum opening angle of the wing can be determined, or the opening angle is adaptable to different heights.

Further advantages, features and details of the invention result from the subclaims and the following Description in the with reference to the drawing two particularly preferred exemplary embodiments in detail are described. You can do that in the drawing shown and in the claims as well as in the Description mentioned features each individually or be essential to the invention in any combination.

1 shows a part in a perspective view a casement 10, on which the housing 12 a first embodiment of a drive for a Crank turn-tilt fitting 14 is placed. The housing 12 is partially broken open, so that parts of the crank-tilt fitting 14 are visible. The housing 12 has one elongated section 16, in which two drives 18th and 20 for a rotary fitting 22 (shown in FIG. 3) or a tilt fitting 24 are accommodated. Laterally next to the elongated section 16 is in the direction to a glass pane, not shown, a cylindrical one Section 26, on which a crank 28 is placed is. The crank 28 is with a crank handle 30 over which the crank-tilt fitting 14th is operated. Within the cylindrical section 26 there is one shown in FIGS. 7 and 8 Differential gear 32, via which the drives 18 and 20 are driven.

The two drives 18 and 20 are coupled, but only successively longitudinally displaceable, d. H. in the longitudinal direction of the Casement 10 slidably in a guide bed 34 stored, which is shown in Figure 5. This Guide bed 34 has an elongated structure and is in a precisely fitting recess 36 in the casement 10 used.

The two drives 18 and 20 have on their undersides each have an extension 38 and 40 for actuation the fittings 22 and 24 serve by the extension 38 in engages the conventional rotary fitting 22 so that it can be moved in the fitting groove 42 in the casement 10 can. The rotary fitting 22 corresponds to the conventional one Hardware for Tilt & Turn windows. The extension 40 has Eye 44 on which a tab 46 z. B. by means of a Rivets, pins or the like can be attached. The Tab 46 is indicated in FIGS. 3 and 6 is shown and with its free end 48 in a Closing plate 50, which is on the fixed frame located, hooked (Figure 6).

It can be clearly seen that the two drives 18 and 20 each with a rack section 52 and 54 are provided, in which the teeth of two gears 56 and 58 (Figure 5) intervene. The two gears 56 and 58 can be formed in one part or two parts, wherein the two gears 56 and 58 only over part are circumferential with teeth, and always in the Sections in which the one gear has no teeth has, the other gear is provided with teeth. On This ensures that when turning both Gears 56 and 58 (which are rotatably connected to each other are), either the one rack section 52 or the other rack section 54 is moved. E.g. in FIG. 5, the gear wheel 56 rotated counterclockwise, then the gear 58 is disengaged from the rack section 54 and the teeth of the gear 56 engage in the Teeth of the rack section 52 and move it from top left to bottom right (with the arrangement according to Figure 5). The teeth of gear 56 come accordingly disengaged from the rack portion 52 if that Gear 56 is rotated in the clockwise direction, then the teeth of gear 58 into the rack section 54 and intervene from the bottom right move top left. The other rack section is then at rest.

In FIGS. 1 and 3 there are conical recesses 60 and 62 recognizable, which are provided in the drives 18 and 20 are. It is also located between the two drives 18 and 20 a web of the guide bed 34 (not shown), which has a further recess, in which is arranged a ball. The ball has one Diameter that is greater than the distance between the two Drives 18 and 20 so that they are laterally across the web survives. This causes the ball to come off the web the guide bed 34 is held and protrudes laterally, engages in the two recesses 60 and 62. Now one of the two drives 18 or 20 moves, then the Recess 60 or 62 from that shown in Figure 1 Escaped and thereby the ball out of this recess 60 or 62 pushed out and on into the other Recess 62 or 60 moved into it. This means that this drive, in which the ball now engages, via the ball is locked to the web of the guide bed 34. The other drive, on the other hand, can move freely. As soon as the align the two recesses 60 and 62 again, the other drive can be moved out of this rest position be, then the ball into the recess of the other Drive is moved in, so that this other Drive is locked to the web of the guide bed 34. The recesses 60 and 62 and the ball form one Locking element 64, which ensures that only one of the drives 18 and 20 can be moved.

FIG. 5 also shows a ring gear 66, which is part of the Differential gear 32 is, and on the two gears 56 and 58 is rotatably placed. The ring gear 66 connect the two gear wheels 56 and 58 to one another, if this has not been done before.

FIG. 6 shows a side view of the casement 10 in the closed and in the tilted position, the Sash frame 10 can be tilted in the direction of arrow 68. The sash 10 is from the tab 46, the Tilt fitting 24 forms, moves and held. The free end 48 of the tab 46 has a pin which is in the locking element 50, which is on the fixed frame, is held in a recess 70. The striker 50 is shown separately in FIG. 6, so that it is more recognizable. Usually it is located Locking plate 50 in the plane of the pivot fitting 18, i. H. in the level of the hardware groove of the sash 10. The Closing plate 50 has a slide 72 with which the Recess 70 can be opened and closed, so that the pin provided at the free end 48 is caught or can be released. 6 the slide 72 is in the closed position and is by means of a locking pin 74 of the rotary fitting from its unlocked position to its open position and relocated back. The locking pin 74 engages in a corresponding with the sash 10 closed Pin receptacle 76 a.

Is caught in the striker 50 and thereby fixed free end 48 of the tab 46 of the drive 20 in 1 moved from top left to bottom right, then the extension 40 also becomes from the top left to the bottom right displaced, whereby the end 78 attached to the extension 40 moved along the casement 10 from top to bottom is, whereby the tab 46 is issued and the sash 10 is tilted, as in FIG dash-dotted lines is shown.

FIG. 7 shows this in a perspective representation Differential gear 32, on the top 80 the crank 28 is put on. With the crank 28, the top 80 and a cage 82 driven. In this cage 82 are like also shown in Figure 8, in two planes one above the other four gears 84 and 86 each rotatably supported. The two gears 84 and 86 are non-rotatable with each other connected. This is done, as shown in Figure 7, either via an intermediate disk 88 or, as in FIG. 8 represented, directly. That in Figures 7 and 8 shown part of the differential gear 32 is in the Ring gear 66 (Figure 5) used so that the gears 86th mesh with the internal ring gear 90 of the ring gear 66. On the Gears 84 become a ring gear (not shown) pushed on, which with the cylindrical portion 26 the housing 12 is connected and thus fixed.

If the transmission 32 is driven by means of the crank 28, then, on the one hand, the gears 84 roll on the fixed, connected to the housing 12 ring gear from and thereby drive the ring gear 66 because the two gears 84 and 86 have different numbers of teeth.

It is considered essential that the rotary function of the Casement 10 from a first drive 18 by means of a separate rotary fitting 22 is realized, whereas the Tilting function of the casement from a second drive 20 and a second tilt fitting 24 is realized. Therefore can with the invention, the conventional turn-tilt fitting can be used, this only in the invention still exerts its turning function and the tilting function over another fitting, namely the tilt fitting 24 with the tab 46 is completed. By means of the crank 28 when the sash 10 is completely locked, the first Rotary fitting 22 by means of the drive 18 from the upper one in an intermediate layer moves in which the locking pin 74 and 92 the sash 10 for a rotary movement release. If the crank 28 is moved further, then the Turned fitting 22 in its end position, in which he locked the sash 10 so that he only can still be tilted. In this position, the one Corresponds to the rest position, the rotary fitting 22, in particular the drive 18, uncoupled from the crank 28 and the Drive 20 and thus the tilt fitting 24 coupled. Becomes crank 28 continues to turn, then sash 10 tilted according to the crank rotation. This means that any intermediate position between the closed casement 10 and the fully tilted casement 10 can be taken. The differential gear 22 is designed so that it is self-locking, so that the Sash 10 stable in any intermediate position maintains. For this tilting of the sash 10 is only the tilt fitting 24 is responsible, but not the pivot fitting 22, which remains in its rest position.

FIG. 9 shows a further exemplary embodiment of a Drive, in which in a housing, not shown central slide 94, two further slides 96 and 98 and Locking devices 100, 102 are provided. The central slide 94 is operated via a crank, a twist grip or another actuator in the housing in it Longitudinal shifted. The central slide takes place 94 over two laterally protruding pins 104 which locking devices designed as control disks 100, 102 with. The control disks 100, 102 are in round recesses of the two sliders 96 and 98 rotatably mounted and have receiving slots 106 in which engage the pin 104. E.g. the central Slide 94 moved from left to right, then the Control disks 100, 102 into which the pins 104 intervene in the clockwise direction by approx. 90 ° turned. The one cone facing away from the viewer, which in the control disk 100 engages, is then caught and takes the first slider 96. The rotational position of the control disc 100 is secured by one of the Control disk 100 protruding locking pin 108 in one Scenery 110 is guided, which e.g. in a housing wall 112 is provided. The first slide 96 is therefore from central slide 94 outwards (in FIG right). If the central slide 94 is pushed back, then the first slider 96 also becomes taken until he the position shown in Figure 9 again occupies.

The central slide 94 becomes leftward in FIG then the two control disks 100, 102, in which the pins 104 engage, against the Turned clockwise 90 ° so that it assume the position shown in Figure 9. The one Pin 104 facing observer is then in the control disk 102 caught and takes the second slide 98. The rotational position of the control disk 102 is secured that a locking pin protruding from the control disk 102 114 is guided in a backdrop 116, which e.g. in a housing wall 118 is provided.

The one not carried by the central slide 94 Slider 98 or 96 is at the end of the backdrop 116 or 110 blocked by its associated housing wall 118 or 112.

The slides 94, 96 and 98 can be relatively flat or thin be trained so that this drive easily in one Casement can be accommodated. You can also use the central slide 94 either via the first slide 96 the rotary fitting or via the second slide 98 Tilt fitting driven, the other fitting always remains at rest.
