Description

The invention relates to a turn-tilt hardware for windows, doors and a Window or door with such a turn-tilt hardware.

A Drehkippbeschlag according to the preamble of claim 1 is known from DE 80 15 677 and in DE 31 11 347 A1.

It is envisaged that the Drehkippbeschlag a drive rod for Control of the turn, tilt and close control has, of a Edge gear is adjustable via a handle. The edge gear points usually in gear, with his teeth in recesses and / or serrations of the drive rod and engages with its axis of rotation a polygon of the handle is coaxially connected. The drive rod is in an open rabbet groove of the wing, which by a faceplate of the Espagnolette fitting can be covered. The faceplate is from Pins penetrated in oblong holes, which are attached to the drive rod and with frame - mounted bolt engagements to adjust the Positions pivot-tilt and close cooperate.

Furthermore, it is provided in the known Drehkippbeschlägen that a Device for securing the wing in a night ventilation position is provided, at the frame side, a holding member with a passage for a pin attached to the drive rod is provided. The pin is in the night ventilation position in a reveal of the device U-shaped embraced and latched therein, the passage being offset laterally of Displacement direction of the pin has, so that the wing in total by the movement of the pin is turned off the frame. This is followed by the pin an inclined guide surface opening into the passageway, attached to the device is provided.

Both according to DE 31 11 347 A1 and DE 80 15 677 U1 is hereby provided that the night vent position by adjusting the handle in a range between the rotational and the tilting position of the fitting is adjustable.

The disadvantage here is that in the usual 180 ° gap path of the handle the setting of the intermediate position, so setting the Night ventilation position, is associated with problems. Because of the lift the Driving rod can exercise using the usual edge gear, is limited by the use of a 180 ° switching path of the handle, stands each pin and each of these associated bolt engagement only one comparatively small section from the total stroke of the edge gear or the drive rod available. As a result, the Assignments of locking engagements and pins are met very accurately or the assignment for example via the in DE 31 11 347 C3 be described adjusting device ensured.

Furthermore, it is disadvantageous that in the described Tilt and turn hardware through the disc, the position of the handle from the outside is visible as this protrudes into the disk, allowing a manipulation through a burglar is facilitated.

The object of the invention is therefore to provide a simple embodiment of the Turntable fitting to indicate the one less visible makes that the wing is in a night ventilation position, the The observer thus has the impression of a locked window mediated, and on the other hand, the assignment of bolt engagement and pin both for the closed position and for any other adjustable Shift position of the fitting facilitates.

This object is achieved surprisingly simply by the fact that the passage is arranged in a longitudinal position of the pin, which adjoins the 180 ° -Schaltweg one of the drive rod driving edge gear connects. By the Extension of the switching path to more than 180 ° is on the one hand one of Outside not visible position of the handle causes a hand lever, the thus in each case by wings and frame hidden from the outside. on the other hand is taking advantage of the already known gear rack connection an extension of the available stroke of the espagnolette fitting achieved.

It is advantageous if the edge gear on the 180 ° -Schaltweg the Controlling the rotational, tilting and closing position allows, since thereby the maintaining the usual operation of the edge gear in a simple manner can be.

It is particularly useful when the gap ventilation position to the Closed position connects, since thereby the holding member and corresponding Bar engagements are arranged adjacent to each other immediately adjacent can.

A development further provides that the night ventilation position a position of the handle is assigned by 45 ° to the vertical. This disappears Handle partly for a behind the glare or wing frame and takes a position in which an influence from outside only with difficulty possible is. In particular, if the handle points down and here still by 45 ° in the invisible space behind glare and sash frames is pivoted, an operation from the outside can only destroy the Slice of the window done. On the other hand, the 45 ° tilt one Use of today's usual handles sure that a 45 ° detent to Emergence of the night ventilation include.

It is further provided that the holding member is a striking plate, which a Having passage as effective closing slot. This can be the Bolt engagement and the holding member Baueinheitlich, so one piece, run. This reduces on the one hand the necessary assembly work and reduces on the other hand, the number of parts to be provided.

A particularly preferred embodiment provides that the pin as Mushroom pin is formed in the closing and gap ventilation position interlocking with the passage or closing slot cooperates. Thereby a locking of the sash is effected relative to the frame, the a burglary comparatively large resistance opposes. Mushroom pin have long been in burglar-resistant fittings known and prevent a relative displacement of the wing relative to Frame, so that the pins and locking bars of the bolt engagements not except Intervention can get.

Particularly advantageous is an embodiment in which the closing slot and the slot a backdrop within the effective as a strike plate Holding member are. This allows the setting of the night ventilation position following the locking position in a simple manner make burglar resistant, a one-piece design of the holding member and the Bolt engagement is guaranteed and there will be a compulsory shutdown of the Sash ensured. The closing slot and the slot are over the inclined baffle joined together.

Furthermore, it can be provided that the handle is a bend which opposes the direction of the over the 180 ° -Schaltweg outgoing adjustment is directed. This allows the Turntable fitting also use in such windows or doors, the one Have wall reveal, in which therefore the frame and / or wings on the Handle side has comparatively close to a wall. The Handle can then despite only a short distance to the wall or soffit perform the beyond 180 ° travel, without to the wall bump.

Furthermore, the invention claims protection for one with such Tilt-and-turn fitted window or door. A further education of such a window with such a Drehkippbeschlag provides that the holding member on the side facing away from the pivot axis frame spar is attached, so that the wing lifts only slightly from the frame.

If a large Abstellbewegung the sash relative to the frame can be achieved, it can further be provided that the holding member on upper or lower frame rail or is arranged at both. This allows the angle that the sash frame relative to the frame occupies, due to the distance of the holding member from the axis of rotation determine.

a tilt and turn window with a turn-tilt fitting,

Fig. 2 to 4

a handle of the tilt and turn fitting and a strike plate with a holding member according to the invention in different switching positions.

In Fig. 1, a frame is generally 10 and a sash completely generally designated 12. The sash 12 is opposite to the Blendrahmen 10 tilted about a tilting axis 14 or about a rotation axis 16th rotatably mounted. For this purpose, at 18 a not shown Provided corner bearing, which both the tilting movement about the tilting axis 14th as well as the rotational movement about the rotation axis 16 permits.

Further, a tilt lock is provided at 20, which the tilting movement about the tilting axis 14 permits and for the rotational movement about the axis of rotation 16 can be opened. Between the upper frame leg 22 of the Blendrahmens 10 and the upper sash leg 24 of the Sash 12 is a Ausstellvorrichtung 26 is provided which the Tilt opening width of the sash frame 12 relative to the frame 10 The position shown in Fig. 1 limited and which during the rotational movement of the sash frame 12 about the axis of rotation 16 on the upper sash leg 24 of the sash 12 is set in parallel position to this, by cooperating bars 28, 30. The bolt 30, the tilting bearing 20 and possibly here not further drawn locking element pairings for Locking the locking of the sash frame 12 on the frame 10 are through Driving rod means 32 controlled in a known manner.

To set a gap opening position is a pairing of a holding member 37 and a pin 36, which together constitute the means for Formation of the sash in the night ventilation position form. The pin 36 is about the drive rod means 32 along the upper sash leg 24 movable, wherein the drive rod of the drive rod means 32 via a the Handle 38 associated edge gear in different switching positions, namely, turning, tilting and closing as well as a switching position gap opening is adjustable.

In Fig. 1, the handle 38 is switched to the switching position tilting and the Sash frame 12 is in tilted position.

In FIGS. 2 to 4, the position of the pin assigned to the handle 38 is shown 36 shown relative to the locking element 34. The are in known Way constructed drive rod means not shown. In the in Fig. 2 with 36 designated pin is designed as a mushroom pin and engages with the Edge 40, the longitudinal edges 42 of a closing slot 44. This is in particular from the representation of the holding member 37 and the pin associated therewith 36. The closing slot 44 is matched to the pin 36 in this case, that its diameter-reduced central portion with little play in the locking slot 44 is transversely displaceable, so that the pin 36 in the axial Direction can not be brought out of the closing engagement and therefore the in Figures 3 and 4 shown shooting and gap ventilation position hooked with the closing slot or the adjoining passage 46 interacts. The effective as a holding member strike plate is in itself known manner attached to the frame 10 of the window or door, wherein the strike plate the rearward engagement of the rim 40 by a distance in axial direction of the pin 36 permits. This is for example by a U-shaped contouring of the strike plate ensures.

In the rotational position shown in Fig. 2, the pin 36 is disengaged with the holding member 37. This does not apply in the same way for one here shown tilting position in which the handle 36 is perpendicular to the top. In the rotational position shown in Fig. 2, the sash frame 12 can therefore order pivot the axis of rotation 16. In Fig. 2 is also the alternative Design of a handle 38 shown, wherein the handle 48 of a first Embodiment straight, while the handle 49 a alternative design has a bend 50. As shown in FIG. 2 still As can be seen, the closing slot 44 is substantially Z-shaped attached and thereby with respect to a transverse to the longitudinal axis Symmetryeachse 51 mirror image also on the opposite side Longitudinal end provided. This allows the strike plate each for both used to the right as well as for left-opening casement 12 become.

Is about the edge gear not shown here in Fig. 3 shown Closed position, the pin 36 is in the lateral opening of the Striker inserted, so that the sash frame 12 relative to Frame 10 is fixed. Here is the handle 48 and 49 of the Handle 38 vertically down.

At the closed position of FIG. 3, the gap ventilation position closes Fig. 4, wherein, starting from the tilting position, not shown - in the Handle 48, 49 stood vertically upwards - the edge gear up to the Closed position of FIG. 3 has undergone a switching path of 180 °. On a further switching path of about 45 ° can over the edge gear and this associated drive rod means 32 of the pin 36 on the Closed position to be moved beyond. In this case, the closing slot 44 forms along with, slot 46 a backdrop through its Z-shaped course inside the strike plate. The pin 36 is on its travel - from the Locking to the gap ventilation position - continuously in the slot 46th and the closing slot 44 and along the soffit forming Longitudinal edges 42 out. About the inclined guide surface 53 of the longitudinal edges 42nd Finally, the pin 36 comes out of the closing slot 44 in the passage or slot 46. The Z-shaped course of the closing slot 44 and the Slot 46 is designed so that the end of the closing slot 44 in Direction of the opening direction 52 of the sash 12 is offset, so that the sash 12 during the displacement of the pin 36 within the Closing slot is spaced from the frame 10. It is in FIG. 4 recognizable that the edge 40 engages under the longitudinal end of the slot 46, which leads to an increased lift safety in this switch position.

By the position of the handle 38 in a perpendicular to the 45 ° inclined Lage, therefore, a gap ventilation position of the sash frame 12 is set in the latter relative to the frame 10 via the pin 36 and the slot 46th is securely set. It is particularly advantageous that the handle 48, 49 through the upright spar 54 of the sash 12 in the Gap ventilation position is covered, so that the switching position of Edge gear from the outside is not readily apparent.

As is clear from Figures 2 to 4 beyond, the bend is 50 so provided that this opposes the direction of the over 180 ° Switching the edge gear outgoing adjustment is directed. This allows such a fitting even with windows or doors Use finds its frame 10 arranged in a niche is. Namely, the wall niche with her reveal 55 is relatively close fitting executed the sash 12, otherwise the over 180 ° switching path Outgoing travel to achieve the gap ventilation position with a Handle 48 can not be set, as this prematurely against the soffit 55 the wall niche would strike.

In the illustration of FIG. 1, the holding member 37 is at the top Blendrahmenschenkel 22 is attached. Of course, other can also Pin 36 with suitable holding members 37 on the other Blendrahmenschenkeln be provided. To get a twist of the However, to prevent sash 12, it must be ensured that either the casement 12 are displaced to the inside of the room as a whole can, for example, by an arrangement of suitable Articulated fittings, as known for example from DE 3043925 C2, on the In this regard, full content is referred to. In such a Design can all located on the casement 12 pin 36 with corresponding holding members 37 cooperate. If this is not the case, then to ensure that with respect to the possible pivot axes by the wing frame 12 executed movement by other bolt engagements not is hampered. This can be done, for example, that with this cooperating pin a correspondingly designed free space in the Connection to the closing slot 24 protrude or its closing slot is sized so that the pins, exclusively for Securing the locking position are suitable, from a longitudinal end of the Lock slot can emerge. Preferably, however, is an arrangement to provide the or the holding members 37, which are either at the top or bottom Frame leg 22, 56 or the vertical Blendrahmenschenkel 57, 58 takes place.

4, the position of the handle 48 in the various switching position hinted again. Of course, in addition to the switching sequence tilting (vertical up), turn (horizontal) locked (not downwards) also the rotary and tilt switch position are reversed. From this it becomes clear that the handle covers a total travel of about 225 °.
