Description

The invention relates to an espagnolette fitting for windows, doors or the like, with locking pins protruding from the actuating rods, which come into engagement in the locking position for holding shoulders of frame-side counter-locking parts and with a device for achieving a gap-open ventilation position of the window sash to the window frame in an intermediate position of the espagnolette. Operating handle between the open and closed positions, which device is formed from a holding pin of the drive rod, which controls over run-in slopes in a catch niche of a striking plate on the frame.

Such an embodiment is known from DE-OS 3 111 347, wherein in addition to the locking rod-side locking pin on the driving rod in the region of the upper horizontal leg of the window, a separate holding pin is provided, which cooperates with the striking plate on the frame. For this retaining pin, the connecting rod cover rail must form a separate longitudinal slot, the width of which is adapted to that of the elongated retaining pin. Furthermore, in order to ensure the safe functioning of this device, a catch bar oriented transversely to the direction of displacement of the drive rod is provided on the drive rod, for which the striking plate forms a separate catch funnel. The disadvantage of this configuration is the complex structure. Then there is no possibility of retrospectively assigning such a device to an already used connecting rod fitting, unless high conversion costs are accepted.

The object of the invention is based on the object of designing a connecting rod fitting of the type described in such a simple manner that subsequent attachment of the device can also be achieved at low cost.

This object is achieved in that the retaining pin is formed by one of the locking pins and the striking plate, immediately adjacent to the counter-locking part on the frame side, has a run-up slope offset inward about the diameter of the retaining pin, the apex zone of which lies opposite a catch shoulder which opens the retaining pin in the open position intercepting a plane which is displaced outwards in relation to the holding shoulder.

As a result of such a configuration, a generic connecting rod fitting with a device for achieving a gap-open ventilation position of the window sash of simple construction is specified. It is now possible to send the locking pin function to a locking pin provided on the drive rod anyway, so that it thereby fulfills two tasks. One is to reach behind the retaining shoulder of the counter-locking part in the closed position and to interact with the striking plate in the open-gap ventilation position. Retrofitting of the espagnolette fittings already used on windows, doors or the like with such devices is therefore permitted in a simple manner. It is sufficient to attach the striking plate in the immediate vicinity of the counter-locking part on the window frame. The special arrangement of the run-on slope, apex zone and catch shoulder of the striking plate allows the master of the gap-free ventilation position despite the relatively thick holding pin in diameter in that the holding pin is then intercepted by the catch shoulder which is advanced outwards of the fold. This catch shoulder is arranged so that it is covered by the sash leg when the window sash is closed. The use of a locking pin to fulfill the holding pin function allows install the device anywhere on the window. A lateral attachment of the device to the window, that is to say to a vertical leg of the same, is particularly suitable. The device can also be used for turn-tilt sashes, turn sashes and tilt sashes. It can also be used on windows that open outwards.

An advantageous further development can be seen in the fact that the catch shoulder is displaceable in the direction of movement of the wing up to over the holding shoulder. This movable design of the catch shoulder allows that no escape niche is to be provided in the support leg of the window sash in the closed position of the window sash.

It proves advantageous that the catch shoulder is formed by the one leg of an angle slider, which leads in the striking plate.

Another advantage is the fact that the catch shoulder is spring-loaded directed inwards to the fold. In the night ventilation position, therefore, the spring exerts a load on the retaining pin in the direction of the apex zone via the catch shoulder, thereby achieving freedom from rattling.

A clearly perceptible locking position is achieved in that the apex zone forms a locking trough for the holding pin.

The fact that the striking plate fastening screw penetrates a longitudinal slot of the guide leg of the angle slide contributes to a simplified design. The striking plate fastening screw therefore fulfills a double function.

Furthermore, it is favorable that the guide leg of the angle slide has widened and angled engagement noses for the spring.

In the case of new equipment, in particular, it has the advantage of forming the counter-locking part and striking plate in one piece.

Finally, an advantageous feature is that the spring is designed as a plastic part surrounding the engagement lugs, which rests in a pocket on the underside of the striking plate. The spring therefore fulfills a damping function in the gap-open ventilation position.

The window designed as a tilt-and-turn window has a window frame 1 and a window sash 2 that closes the latter. The latter can be brought into the rotary oven position about a left-hand, vertical axis. It is also possible to pivot the window sash 2 into the tilt-open position about a lower horizontal axis. Hinges 3, 4 and a tilt hinge (not shown) serve this purpose. Furthermore, a gap-open tilt position of the window sash 2 can be brought about. For this purpose, a device 5 is attached to the right vertical leg of the window.

The various positions of the window sash can be brought about by means of a drive rod actuating handle 6. The latter is attached to the window sash 2 and controls a drive rod gear, not shown, from which a drive rod 7 extends. The drive rod 7 is equipped with locking pins 8 which cooperate with counter-locking parts 9 to be fastened on the frame side. In Fig. 1, a locking pin 8 is shown with a counter-locking part 9.

The drive rod 7 lies in a circumferential groove of the profiled window sash 2 and is covered by a cover rail 10. In the area of the locking pin 8, the cover rail 10 forms a longitudinal slot 11, which is penetrated by a section 8 ′ of the locking pin 8 with a smaller cross section.

In the closed position, the locking pin 8 engages behind a holding shoulder 12 of the counter-locking part 9. The corresponding positions of the locking pin 8 and the actuating handle 6 are designated by the numbers I-IV, see FIGS. 1 and 4. The counter-locking part 9 is of an angular cross-section, whereby which represents an angle leg, the holding shoulder 12. The other angle leg 13 engages in a profile groove 14 of the window frame 1 and is fixed there by means of a screw 15. The outer surface 12 'of the holding shoulder 12 is flush with the front surface 1' of the window frame 1.

A striking plate 16 is fastened to the window frame immediately below the counter-locking part 9. In cross section there is an angular configuration of this striking plate. One angle leg 16 'has a run-up bevel 17 which is offset inward approximately by the diameter D of the locking pin 8, while the other angle leg 16 "is supported on the inner stop surface 1" of the window frame 1. In order to be able to use the striking plate 16 for left and right stop, there is a symmetrical design around a horizontal central axis. This means that the angle leg 16 'forms a further run-up slope 17'. The run-up bevels 17, 17 'merge into a central apex zone 18 which forms a locking recess and which is adapted to the diameter D of the locking pin 8.

The apex zone 18 is opposite a catch shoulder 19, which is formed by one leg of an angle slide 20. The latter is guided with a leg 21 in the striking plate 16. A longitudinal slot 22 of the same is penetrated by a striking plate fastening screw 23. The guide leg 21 is widened in its area opposite the catch shoulder 19 and there has angled engagement lugs 24 for a spring 25. This is designed as a plastic part comprising the engagement lugs 24 and is located in a pocket 26 that extends from the underside of the striking plate 16. The catch shoulder 19 is held in a neutral central position by the spring 25, see FIGS. 6 and 9.

A bar 27 attached to its underside contributes to a firm fit of the striking plate 16. For this purpose, pins 28 extending from the underside are used, which engage in corresponding openings 29 in the strip 27. When the striker plate is screwed on, the strip 27 enters the groove 14 in the window frame 1 and causes the striker plate 16 to be secured against rotation relative to the window frame.

The locking pin 8 shown in the drawing performs the function of a holding pin.

• Soll der Fensterflügel 2 ausgehend von der geschlossenen Stellung in Fig. 1 bis 4 in die Drehoffenstellung gebracht werden, so ist der Betätigungsgriff 6 in Uhrzeigerrichtung um 90° in die Position II zu schwenken. Von der dabei mitgenommenen Treibstange 7 wird der Haltezapfen 8 in Position II in Fig. 4 gebracht. Er hat somit die Halteschulter 12 verlassen und liegt im Durchtrittsspalt zwischen Fangschulter 19 und Halteschulter 12, was das Schwenken des Fensterflügels 2 um die linksseitige Drehachse zuläßt. Wird jedoch eine spaltoffene Kippstellung des Fensterflügels 2 erwünscht, so ist der Betätigungsgriff 6 in die Lage III zu bewegen, also um 45° weiter. Dabei beaufschlagt der Haltezapfen 8 die Auflaufschräge 17 und wird von dieser in den Bereich zwischen Scheitelzone 18 und Fangschulter 19 gesteuert, siehe Position 111 in Fig. 4. Einhergehend mit diesem Bewegungsablauf wird der Fensterflügel 2 um einen Spalt vom Festrahmen abgedrückt, und zwar um die untere horizontale Kippachse. In dieser spaltoffenen Lüftungsstellung, vergl. auch Fig. 5, fängt die Fangschulter 19 den Haltezapfen 8 auf einer gegenüber der Halteschulter 12 falzauswärts vorverlagerten Ebene ab. Dies kommt daher, daß der Durchmesser D des Haltezapfens 8 größer ist als das Maß x zwischen Scheitelzone 18 und Halteschulter 12, vergl. Fig. 4. Die Feder 25 übt nach dem Eintritt des Haltezapfens 8 zwischen Scheitelzone 18 und Fangschulter 19 eine gewisse Druckbelastung auf den Haltezapfen 8 aus, so daß das Herbeiführen dieser Stellung als Raststellung fühlbar ist.

This works as follows:

• If the window sash 2 is to be moved from the closed position in FIGS. 1 to 4 to the rotary kiln position, the actuating handle 6 must be pivoted 90 ° clockwise into position II. The holding pin 8 is brought into position II in FIG. 4 by the driving rod 7 that is carried along. He has thus left the holding shoulder 12 and lies in the passage gap between the catching shoulder 19 and the holding shoulder 12, which allows the window sash 2 to be pivoted about the left-hand axis of rotation. However, if a gap-open tilting position of the window sash 2 is desired, the actuating handle 6 must be moved into position III, that is to say by 45 °. The holding pin 8 acts on the run-up slope 17 and is controlled by the latter in the area between the apex zone 18 and the catching shoulder 19, see position 111 in FIG. 4. Along with this sequence of movements, the window sash 2 is pressed a gap from the fixed frame, namely by the lower horizontal tilt axis. In this gap-open ventilation position, cf. also FIG. 5, the catch shoulder 19 catches the holding pin 8 on a plane which is advanced in front of the fold away from the holding shoulder 12. This is because the diameter D of the holding pin 8 is greater than the dimension x between the apex zone 18 and the holding shoulder 12, see FIG. 4. The spring 25 exerts a certain pressure load between the apex zone 18 and the catching shoulder 19 after the entry of the holding pin 8 the holding pin 8 off, so that the bringing about of this position can be felt as a locking position.

The window sash can also be brought into the tilt-open position from the gap-open ventilation position by turning the actuating handle by a further 45 ° clockwise. As a result, it reaches position IV according to FIG. 1, while the holding pin moves into position IV according to FIG. 4. It is then no longer in the area of the catch shoulder 19, which allows the window sash to be tilted accordingly.

By turning the handle 6 in the opposite direction, the window sash can be brought back into the closed position, the holding pin moving through the gap between the apex zone 18 and the catch shoulder 19. Then the run-up slope 17 'serves as a control aid.

In the embodiment shown in FIG. 10, a counter locking part 9 'and a striking plate 16' are integrally formed with one another. The holding shoulder 19 is guided on the transverse central axis of this one-piece component, on both sides of which the holding shoulders 12 extend. It is possible to use this unit for both right and left hinges. Across from the catching shoulder 19 is the apex zone 18 with run-up slopes 17 and 17 'emanating therefrom.

All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
