Display device for swivel chin wing from Windows or the like . The invention relates to a display device for rotary Tilting sash from Fensterre or the like: with two - preferably recorded concealed in the wing gap - in the vertical Pivot arms mounted on the frame tilted wing at an acute angle to each other, where- at the sash-side pivot point of the shorter extension arm Slidable in a slot above the top of the wing is led. Such display devices sirid in different, luscious forms of leadership known. In such a well-known exhibition device, the longer extension arm protrudes over the top of the sash side out and is on the with the help of a screw lever Hinged wing, with a special control device in Shape of a pen and a slot is necessary to make the -iteuerzing the I ewegixng of the wing depending on the Movement uni; the at-j "control device.

In this arrangement, the extension arms consist of simple members that can be articulated independently of one another both on the sash and on the frame. The movement of the arms is independent of each other, so that no special attention needs to be paid to the kinematics during the movements between the positions of the sash. Nevertheless, safe guidance is ensured, firstly because the longer extension arm is designed to be free of play at all points of articulation and secondly because the two arms work together, at least in the closed position and in the open tilted position, so that the position of the two arms is mutually exclusive are influenced. In particular, in the tilted open position, the articulation point between the two parts of the longer extension arm supports this longer arm on the short extension arm, so that the short extension arm forms a fixed deflection for the largest open position. On the other hand, in the closed position of the small Ausstel bar against this articulation point, so that the position of the two extension arms is in direct mutual relationship in this position. Between these two end positions, the two arms can move independently of one another and also assume different positions, so that the shorter extension arm and the articulation point of the two bear against each other. Parts of the longer extension arm not on the whole :: lay between the two end positions of the extension arms and does not need to be present either.

The short extension arm and the compensating arm are advantageous with the bearing point on the frame each over a short distance from the bearing point to Angled facing towards the frame, connected to each other. Can also be expedient for the interaction of the two extension arms at the articulation point of the two parts of the longer extension arm one cooperating with the inner edge of the shorter extension arm Extension or a pin can be provided.

The above-described construction of the opening device according to the invention is of particular advantage in connection with an upper locking bar which, in cooperation with a bearing pin on the frame, forms the upper pivot bearing for the sash. Herzu it is provided according to the invention that the known locking member is hinged to the associated locking rod and is necessarily pivotable transversely to the longitudinal movement by means of a cam on a control member fixedly arranged on the wing depending on its displacement movement. Due to the swiveling training and the forced actuation of the locking member becomes a larger one Tightening) he% @ I scored this bigger one for the lying nose The tightening area in turn has the advantage that the tightening movement of the shorter ALsstellarm in the closed position is pressed firmly against the articulation point between the two 'files of the longer extension arm, so that a firm connection and locking between the extension arms and the wing with the help of the pivotable locking member is achieved. This results in a very simple and reliable mounting of the wing for the rotary movement.

If the sash was in the rotary position, the actuating linkage would inadvertently be is adjusted to the tilt position, as is well known, the H ° lü -el loosens somewhat from the upper Orehlger. It is true that in this position it is possible to detect incorrect operation return the operating linkage to the normal rotational position, whereby also moves the locking member accordingly. However, since the wing differs from the has lifted the upper linging point, the locking lug of the: -tick link engages the bearing pin of the window frame over, so daA. Proper storage of the Wing in the area of the upper pivot bearing is not reached.

(Tm here to remedy the situation and inevitably ensure that, in the event of such an incorrect operation, the sash is on the bearing side against the frame is, sees the crfinding in a more detailed execution form that the longer extension arm close to its sash 11 se3 t Igen FtL..ä @ le'tld: @e a suit cam attfweisi - Jer Transitional tilted positions interacts with a raw pin of the locking rod. The rolling pin moves over the neck of the pull when moving between the tilt position and the rotation position. The drive over can only take place if the longer extension arm is in the position relative to the sash that it assumes in the closed position or in the rotated position of the sash. When: iickste? Jung from the tilted position to the pivoted position means that the longer extension arm is inevitably brought into the desired position by the - @ ollzapfen-4, but in this position the longer extension arm also controls the shorter extension arm, in which the outer joint parts of its two `` files '' rests against the inner edge of the shorter extension arm, the shorter extension arm is also in position during this Z-displacement movement - controlled, theeYn of the locking position or the turning position ment takes. This means that the 'transfer of the Linkage from four tilted positions into the pivoted position of the gel on the storage side automatically to the frame like this her - n-pressed that the locking pin of the locking member at this movement with security behind the Laäerzapfen des i31frame zips. It is particularly advantageous if, as previously indicated, the itegel member can be pivoted on B i ettintigun. linkage is mounted; so that. its locking nose has a greater tightening travel or in the tilted position of the Gesiln-es with the. Wing a relatively second i -., Inla.uf- gap forms for the bearing pin on the frame, so that the g; cr @ nsc ° ite mi.ia-; riff between these two 'file with Security comes about.

, The interaction between the suit socketa and the police pin according to the The invention is also used to advantage to control the pressure movement of the wing from the open tilt position to the desired position to control and support. Since the rolling pin with 3 @ .qi. Tightening cams is only in intermediate positions between the Tilt position and the rotary position of the linkage interacts, finds a lock between the opening device and the wing via these parts does not take place.

The invention is shown in the following on the basis of schematic drawings explained in more detail using several exemplary embodiments. Fig. 1 is a plan view Wings of the genus in question.

The new opening device is used for a turn-tilt sash 2, the is hinged to a frame 1. On the wing is a familiar @ t3'ese Actuating lever 3 mounted, which is indicated by dashed lines, in three different Positions swiveled `ground. The lever 3 is shown in FIG Embodiment in the closed position, while from this first in the threatening position and can be converted from this to the tilt position. The wing is with-de m frame 2 connected via at least three connection points 4, 5 and 6, wherein.

the articulation point 4 is a well-known double joint, which omits both the tilting movements and the turning movements of the wing, while the bearing points 5 and 6 are alternately effective. The upper bearing 5 is a pivot bearing, while the lower bearing 6 is a tilting bearing. The control of these bearing points takes place via the actuating linkage which can be operated by the lever 3 and which is mounted in the sash in the exemplary embodiment shown. Jie Fig. 2 illustrates., Comprises a display device a longer extension arm 6 and a shorter extension arm arm 7. The longer Au2Y # 3tell arm 6 consists of the actual chen, o: @sl: ellarm and:, on which the '.'eil is backlash-free at 12 aasgelenken. The 'feil 6 is on! others End at 8 with no play at the top of the wing, ls 2 aasge- directs. The compensation arm 11 is angled as shown. kelt- and with its other earth in the "area of the axis of rotation pivotally mounted on B1endrahmn 1. , The shorter display area ° 7 is also attached to its frame side bearing is angled and directly bar also in axis 5 of the sash on the frame stores. The other end of the shorter Ausstellarww 7 engages in the usual d't @ iron in the guide slot of a guide plate ches 10 on the wing. Vie Fig. 3 shows the shorter extension arm? and the äusglei chsarm 11 independently of each other on the bearing pin d of the frame. The illustration in Fig. 3 speaks to a section along the section line III-liI in Fig: 2e. In Fig. 2a the wing is shown in the closed position. It can be seen that in this position the shorter poor ? with its inner edge against the pivot pin 12 the articulation point between the two-on 'files of the longer one lg @ r @ tell. @@ es a_rle; t.

In this open position, ler forms shorter ones Extension arm? a stop for the longer extension arm 6, so that this clearly defines the open tilt position is true. - "You can also see from Fig. 2b, which is an intermediate position of the sash when moving out of the closing position 1ing in the open position shows that the two stc: ll.arms 6 and 7 not - are in mutual contact, rather, they are independently of one another around the bearing pin 5 move. with the help of the independent storage of the two Extension arms and in connection with the compensation arm 11 it is achieved that the wing at its Bevregun; en between the closed position and the tilt position are clearly parallel. is performed without the resulting different lichen: L @, ngenärrderrderrderrderrderrderrderrder a corresponding training the articulation points of the longer # `russtelllarmes. in particular be compensated by considerable articulation play of this arm the must. Due to the backlash-free mounting of the parts of the Rather, geren extension arm is a secure support of the wing guaranteed. To form the upper rotary slider 5, the wing is according to Fi: 5 with the help of an iziegelbleches 22 on the upper rotary la-er fixhar. For this "deck" is the transom 22 at. an upper part 1n the case not recognizable xZ7legelstLzil-e 13i1 < 1 -T ° eift 3i1 the rotary position of the with a locking lug 22a behind a roller 5a of the upper bearing on the frame. As FIG. 5a shows, in the closed position the locking lug engages behind a fixed locking plate of the window frame in order to lock the sash on the upper pivot bearing on the window frame. In the position 5b, which corresponds to the rotary position of the sash, the locking plate 22 with its locking lug 22a only engages behind the mentioned roller 5a of the upper bearing, but no longer behind the strike plate 5b.

In the embodiment shown, the strike plate 22 is with Help of the pin 21, pivotable on the locking rod, not shown, of the actuating linkage stored. Furthermore, the locking plate 22 has a control curve in the form of a double-ended Slot 24a, 24b, in which a fixed pin 23 of the wing engages. Of the a section 24a runs parallel to the longitudinal extension of the locking plate 22, while the second part 24b of the slot, which adjoins this, to the outside is angled. It can be seen from Figure 5 that between the closed position and the Rotational position according to FIGS. 5a and 5b of the slot section 24a on the pin 23 slides when the latch plate 22 is moved back and forth. When the operating linkage however, when the threatening position is transferred to the tilt position, the moves second part 24b of the guide slot over the pin 23, whereby the locking plate 22 is pivoted about its pin 21 so that the locking nose 22a of the Wing. 2 takes off. This withdrawal plays a role in the opening process only a minor boll. However, when the sash moves from the tilt position to the closed position is transferred, in this way there is a relatively wide inlet slot for the roll 5a formed, while with the help of the pivoting path of the locking plate-22 relatively large Tightening travel is achieved. This pull-in travel is of particular importance in twofold Respect. Once this tightening path ensures that in the closed position the inner edge of the shorter extension arm 7 firmly against the pin 12 of the two Parts of the longer extension arm is pressed. On the other hand it will be fine This training ensures that in the event of an incorrect operation of the rotated Wing, in which the fixing of the wing on the upper pivot bearing is canceled and the sash lifts off the upper pivot bearing and the frame, the probability enlarged, that when the operating linkage is returned from the tilt position in the turning position the locking nose is still behind the role despite the raised sash 5a of the journal 5 of the upper pivot bearing can grip.

This Zingriff for the return of the wing and the operating linkage in the correct position after incorrect operation is further enlarged by the embodiment according to FIG. 4. In this, as in connection with FIG. 2 shows, on the longer extension arm 6, namely near its articulation point ö dm wing a tightening cam 17 is provided, which is in the path of a round pin 16; matures, which is connected to the upper locking bar of the operating linkage. The arrangement is made so that the neck 17 in the area of the movement path of the rolling pin 16 protrudes between the tilt position and the rotational position of the Actual mastery lies.

Alan recognizes, if from the position according to Fig. 2d, the rotary position, accidentally moved the operating linkage from the rotary position to the tilt position is transferred, so that the wing comes free from the upper pivot bearing 5, the rolling pin 16 assumes the position shown in FIGS. 2b and 2c. One Return of the operating linkage from the tilt position to the rotary position # is only possible when the rolling pin 16 drives over the tightening cam 17. A run over of the tightening cam 17 is only possible in the .Ststellung, which the extension arms assumes in the positions according to Fig. 2a and Fig.-2d. The rolling pin therefore brings the longer extension arm 6 inevitably when it moves out of the Ki = @ pposition into the rotary position into the position according to FIG. 2a or 2d. Since this is the point of articulation 12 attaches to the inner edge of the shorter extension arm 7, is during this movement the shorter extension arm 7 also necessarily in the Siel-Jung according to Fig. 2a or 2d transferred. During this movement, the warehouse-side find the Sash brought up to the frame or: transferred into such a position, in which the locking lug 22a of the sheet metal, on further actuation of the linkage again reach behind the roller 5a of the bearing pin with security can. This purpose is of course also achieved without the measure according to FIG. however, the combination of the measure according to FIGS. 4 and 5 to a particularly large one Security leads. The measure according to FIG. 5 alone can also be sufficient in many cases the sash after operating errors and when returning of the actuating linkage back into the correct position in relation to the upper one Bring pivot bearing.

A.an recognizes that the interaction between rolling pin 16 and tightening cams 17 also helps to move the sash from the open tilt position into the To transfer closed position.

It can also be seen that the rolling pin cooperates with the iinzugnocken 17 only at the transition between the tilt position and the rotary position, a locking in one of the three f, 3rd positions of the linkage between the extension arms and the wing with the help of the tightening cam does not take place .
