Description

The invention relates to a night ventilation device according to the preamble Claim 1.

Are known Ausblscheren for tiltable, especially for swivel and tiltable wings (also tilt or tilt-turn wings) of building windows and Building doors. Also known are tilting or turn-tilt fittings, the are intended for such wings and each have a Ausstellschere, with the limits the maximum tilting or tilting opening movement and thus the maximum tilt position is set.

It is often desirable for tilt or turn-tilt wings, for the wing a secured tilting or intermediate position between the maximum tilt position and the To allow closed position, and for a reduced ventilation gap, in the the wing found or at least so far secured that he only by Overcoming a certain force can be moved from this intermediate position.

A device which has such a secured intermediate position of the wing allows is referred to as "gap ventilation device" in the context of the invention.

Known is a wing lock (DE 91 00 374.1), which consists essentially of a a frame pivotally provided lever consists, which in Longitudinal lever has successively a plurality of ratchet teeth. The Ratchet teeth act with a bolt-like, provided on the sash Collapse locking element, in such a way that in the respective, by the Wing lock secured tilting the locking element in a ratchet tooth of the swung lever is engaged. The wing lock is in addition to the Ausstellschere the turn and tilt window provided. Disadvantages include that the wing lock visible and thus visually disturbing mounted on the frame is and represents an additional structurally complex functional element. Of the Wing catcher thus disturbs not only the visual appearance of the window, but also requires an additional manufacturing and assembly costs.

Also known is a locking device for opening limitation of tilt and Folding wings (DE 24 51 556 A1). In this known device are the Function elements for opening limitation, d. H. for the gap opening in the Ausstellschere integrated, as a cooperating with a toothing Locking member. The locking member is formed at the end of a pin, over which the stay arm the Ausstellschere in a sliding guide a faceplate of the turn-tilt fitting slidably and also pivotally guided. The locking member acts with a Serration together, which is provided on a drive rod of the fitting and by actuating the drive rod from a non-operative position into one effective and thus the locking member locking position is movable. A disadvantage of This known training are u.a. the relatively complex construction and the The fact that a reliable continuous use of these known Ausstellschere not is guaranteed, since the game is relatively large in such a pair of scissors or at Use by signs of wear still increased. Besides, it is necessary, for locking the respective intermediate position (night ventilation position) to actuate the actuating or locking lever of the fitting accordingly is cumbersome and a deviating from the conventional getting used to Operation requires.

Also known is a Ausstellschere (EP 0 960 999 A 1), the intermediate positions or night ventilation positions made possible by spring means are provided, the create a spring force opposite to the tilting opening movement. These Spring means are slidable on the wing-side fitting in a sliding guide and pivotally held end of the Ausstellarmes and tension this in one the closed state of the wing corresponding position. The disadvantage is at this known Ausstellschere that when tilting the wing from the closed position in the tilted opening position the force of the spring as well as a not insignificant Frictional force must be overcome. Especially the frictional force leads to a increased wear and unacceptable noise. Furthermore results in particular at a higher wing weight no safe Intermediate position or gap ventilation position for the wing.

The object of the invention is to show a simplified night ventilation device, whose functional elements are obscured, d. H. optically not visible on the wing and on the Frame or are provided on the functional elements of a Ausstellschere. To solve this problem is a gap ventilation device according to the Claim 1 is formed.

The night ventilation device according to the invention can be particularly simple and be realized cost. This is for example on a Ausstellschere conventional design as an additional functional element only a gap ventilation spring required, which then e.g. is mounted on the fitting or on the faceplate and interacts with a counter-latch, which is provided for example on the stay. The counter-detent is preferred by a required on the stay anyway Closing plate formed.

The night ventilation spring takes up only a small space and can be simple be mounted, especially as retrofit. Furthermore, the Night vent spring as molding made of plastic, for example as injection molded part Plastic can be made particularly simple and inexpensive.

Excessive friction and associated excessive wear are included avoided the invention as well as a non-tolerable noise. The usual, the user familiar operation of a wing or on this wing provided tilting fitting or turn-tilt fitting are by the inventive design not changed, d. H. the usual operation becomes maintained.

Part of the actuated in a known manner via a handle 3 fitting is u.a. a Tilting or Ausstellschere 4, in the upper horizontal rebate area of the wing. 1 and the frame 2 is provided: The Ausstellschere 4 is in itself known manner from a stay 5, which at one end by means of a bearing. 6 hinged on the frame 3, u.a. for pivoting about the axis VA. The other end of the Ausstellarmes 4 is approximately in the middle of the wing 1 at a in Sliding of the sash mounted faceplate 7 of the turn and tilt fitting sliding and pivotally guided, with the help of a at this end of the stay 5 provided joint or head bolt 8, which forms a guide in a and in the longitudinal direction, the stub rail extending slot 9 for pivoting and axial displacement in the direction of the longitudinal axis of the faceplate 7 is performed. The Ausstellschere 4 also has in a likewise known manner an additional arm or lever 10, which at one end by means of a hinge pin 11 on the stay and hinged at the other end by means of a hinge pin 12 on the faceplate 7 is and in the representation chosen for the figure 2 in a plane below the Ausstellarmes 5, but above the top 7.1 of the faceplate 7 is located.

The turn-tilt fitting is designed as a drive rod fitting, i. at the Faceplate 7 is a drive rod 13 axially and in Stulpschienenlängsrichtung for slidably guided a stroke of predetermined length. The drive rod 13 is located on the side facing away from the extension arm 5 and the additional arm 10 bottom 7.2 the Stulpschine and is provided with a plurality of bolts formed by pins 14, the each protrude through a slot 15 on the top 7.1 of the faceplate 7. Each bar 14 is on the faceplate 7 facing bottom of the Ausstellarmes 5 attached to this underside a closing plate 16 assigned.

Each closure plate 16 is in the illustrated embodiment, a molded part of a suitable material, for example of metal or zinc injection molding and is in essentially formed as a rectangular plate which at one end or at one Slab narrow side is rounded at 17. At the bottom 16.1 has the Closing plate 16 projecting, molded pin 18, which attaches to the Arm 5 allow by riveting.

At the top 16.2 is each closing plate 16 with a longitudinal direction of this Plate extending groove 19 formed open at the other narrow plate side and at which the rounding 17 having narrow side is closed. In this groove 17 engages the associated latch 14 when locked on the faceplate 7 Ausstellarm 5 on. About the open end of the latch 14 when locking and unlocking in the Groove 19 inserted or moved out of this. On the outer surface of the rounded end 17, each closing plate 16 is provided with a recess 20, which is formed part-circular in the illustrated embodiment, to a curvature axis perpendicular to the plane of the underside of the closing plate 16. Die Closing plate 16 may at the end 17 and two or more than two recesses 20, which are offset in the transverse direction of the closing plate against each other.

Each closing plate 16 is also mirror-symmetrical to a longitudinal axis of the rectangular closing plate enclosing and perpendicular to the plane of the Bottom-oriented center plane M1 executed.

With closed and locked wing 1 are 5 outrigger, additional arm 10 and Faceplate 7 congruent to each other and each bar 14 engages in his Closing plate 16, whereby the extension arm 5 is locked to the faceplate to to keep the wing 1 in the closed state or about the axis VA to be able to pivot. By appropriately moving the drive rod 13 are at in the closed position located wing 1, the closing plates 16 of the bars 14th released, so that the wing 1 pivoting the Ausstellarmes 5 relative to Faceplate 7 and under sliding of the head bolt 8 in the slot 9 to open can be tilted. The maximum tilt position is reached when the Head bolt 8 against the additional arm 10 facing the end of the slot 9th is applied.

In many cases, it is now desired not to completely cover the wing 1, i. in his maximum To tilt in the open or tilted position, but in an intermediate position, the between the closed position and the maximum tilt position and in the one only Narrow ventilation gap between the frame and the wing is. To this, too allow is on the top 7.1 of the faceplate 7 a gap ventilation spring 21st attached.

The design of this spring is shown in Figures 4 - 5 in detail. In the illustrated embodiment, the gap ventilation spring 21 is a molded part of a suitable tough and permanently elastic plastic. It consists of a spring body 22 with top 23 and bottom 24 and one of this spring body 22nd molded lateral locking lug 25. The spring body 22 is shown in the illustrated Embodiment designed as an approximately rectangular plate, namely in the Representation of Figure 5 with a lower peripheral side 22.1, an upper Peripheral side 22.2 and two longitudinal sides 22.3 and 22.4. On the long side 22.4 is the Locking lug 25 is formed, which extends along this longitudinal side from the peripheral side 22.1 extends to the region of the peripheral side 22.2, within the planes of the top 23 and bottom 24 is located and spaced from the longitudinal side 22.4, wherein this Distance increases with increasing distance from the peripheral side 22.1.

The spring body 22 is in a partial region 22 ', which is also the peripheral side 22.1 has formed so that there the top 23 and the bottom 24 parallel lie to each other and according to the thickness of the plate-shaped spring body spaced apart from each other. In a subsequent to the peripheral side 22.2 down and this peripheral side having further portion 22 "is the spring body 22 slightly beveled at the top 23 and bottom 24, in such a way that the Distance between the top and bottom in this section 22 "outgoing slightly decreases towards the peripheral side 22.2. Accordingly, the locking lug 25th shaped at the top and bottom.

At the portion 22 ', an opening 26 is provided, which is for fastening the Night vent spring 21 on the faceplate 7, for example, by riveting or Screws are used. Furthermore, at the portion 22 'in the top 23 and in the Bottom 24 opposite the opening 26 offset two blind holes 27 formed, the for torsionally secure attachment of the night ventilation spring 21 on the faceplate. 7 take appropriate provided on the top 7.1 pin.

In the region of its free end is the locking lug 25 with two bead-like notches 28 and 29 provided, which are offset in the longitudinal direction of the locking lug 25 against each other.

As FIGS. 4 to 7 furthermore show, the night ventilation spring 21 is mirror-symmetrical to a median plane M2 formed in the middle between the top 23 and bottom 24 extends, so that the gap ventilation spring 21st optionally for wing 1, which are opened when turning to the left, or for such can be used, which are opened when turning to the right.

As the figure 2 shows, the gap ventilation spring 21 with its portion 22 'on the 7.1 top side of the faceplate 7 fixed so that they are connected to the section 22 " and with the free end of the locking lug 25 having partial length of this locking lug protrudes beyond that longitudinal side of the faceplate 7, the tilted wing 1 the Ausstellarm 5 faces and with this forms an acute angle. The Night vent spring 21 is further secured so that the latch 25 when closing the tilted wing 1 before reaching the final closed position, first the catch 28th and then upon further closing of the catch 29 on the recess 20 a Locking plate 16 engages. This results in two tilting or intermediate positions for the wing 1, in which between the wing 1 and the frame 2 only one reduced ventilation gap remains, namely when snapping the latch 28 in the Counter catch or recess 20 a ventilation gap greater width than when snapped the catch 29 in the recess 20th

The gap ventilation spring 21 is further fastened so that the latching lug 25 the Additional lever 10 as well as that of the head bolt 8 and the slot 9th formed facing the joint. This orientation of the locking lug 25 has considerable Advantages. When tilting the wing 1 from its closed position into the opening position or In fact, tilting position becomes the extension arm 5 with its one end in the slot 9 in FIG Direction of the gap ventilation spring 21 moves, so that thereby when locking a catch 28 and 29, the engagement of this catch is reinforced in the counter-latch 20, while the Moving the wing 1 in the closed position by moving the Ausstellarmes 5 in the slot the disengagement of the latch 28 and 29 and the counter-lock 20th is supported. This means that the gap ventilation spring 21 in the respective Intermediate position the wing 1 in particular against unwanted further opening (for example, by the sash weight) reliably secures.

Both in the final closed position, as well as in the maximum tilted position the gap ventilation spring 21 out of engagement with the on the associated closing plate sixteenth formed Gegenrast 20.

In the closed position of the wing 1, the gap ventilation spring 21 and their Spring body 22 disposed between the extension arm 5 and the faceplate 7.

The at least one locking lug 25 is in a plane parallel to the top 23 and Bottom 24 resiliently pivotable and thus attached to the face-plate 7 Gap release spring 21 in a plane perpendicular to the axis of the head bolt 8 and perpendicular to the pivot axis of the head bolt 8 and the slot 9th formed sliding swivel guide. This is also in an axial direction perpendicular to the top 7.1 of the faceplate 7 flat training of Ausstellschere 4 a sufficiently large travel for the latch 25 possible.

FIG. 8 shows in a representation similar to FIG. 5 as further possible Embodiment, a gap ventilation spring 21a extending from the gap ventilation spring 21st only differs in that the local spring body 22a formed narrower and the locking lug 25 corresponding detent 25a is made shorter and only a catch, namely the catch 28 has.

The inventive construction has the advantage that as a night ventilation device in essentially only a single component is required, namely the example of Plastic spring 21 or 21 a, and that as a counter-detent for this spring a Any existing strike plate can be used. Further advantages are u.a. a very simplified assembly, even with the possibility of retrofitting the Night ventilation device or the night ventilation spring. The usual function and Operation of the turn-tilt window or the corresponding fitting remains so that a simple and understandable to the user operation is possible.

The invention has been described above by means of exemplary embodiments. It understands that many changes and modifications are possible without As a result, the invention underlying the invention is abandoned.

So it was assumed above that the gap ventilation spring 21 and 21 a to the faceplate 7 is attached. Basically, there is also the possibility of this For example, retrofit the spring with the fitting already installed and then through corresponding openings in the faceplate 7 and in the drive rod 13 therethrough to screw on the frame of the wing 1.
