Description

The invention relates to a tilt latch closure for windows and / or doors, with a tilting bow, which is rotatably mounted about a tilting mirror axis of rotation perpendicular to a sash plane, which is fixedly arranged relative to a cuff rail, and arranged with the tilting bar drive means which in Counter-locking means, which are synchronously movable with a push rod, are engageable, the tilting bar having a first tilting bar area with a tilting mirror shaft and closing means and a second tilting bar area with the toothing means, wherein the closing means are designed as Hinterkrallungsvorsprung, and with a arranged on a window frame closing plate for Recording the Hinterkrallungsvorsprungs, wherein the Hinterkrallungsvorsprung can engage behind a wall of the strike plate positively. Such flip-over buckles serve to lock the sash of a window or door to the frame, the mating drive means being integrally connected to the push rod.

From the EP 1 008 713 A1 is such a known as locking device Kippriegelverschluss known. The bolt is pivotally mounted on the faceplate and has a pointing in the direction of movement hook as Hinterkrallungsvorsprung. In the retracted Condition of the bolt has the faceplate thereby a rugged surface.

The DE 298 00 735 U1 discloses a bolt fixedly mounted on a longitudinally displaceable drive rod. The bolt is T-shaped in cross-section and stands out permanently over the faceplate disturbing.

From the DE 202 10 194 U1 is a swing bolt lock for windows known in which a wing-side pivot bolt is pivotally mounted about a stationary axis of rotation and in a frame-side closing plate is pivoted and this engages behind partially. The drive of the pivot bolt is carried out by a used as an intermediate element between the pivot bolt and push rod transmission device. The pivot bolt is designed like a sickle and engages behind the Schließblleich with the front sickle area.

A disadvantage of such a pivot bolt arrangement that for transmitting the movement of the push rod on the pivot bolt another component in the form of the transmission device is required. As a result, the size of a certain minimum, which is required to accommodate the transmission device, not fall below. Due to the crescent-shaped design of the pivot bolt, a surface texture interrupted in relation to the surface of the faceplate also results in the closed state in the region of the sickle-bow interior. Cleaning of the fitting is made difficult.

From the DE 91 06 906 U1 is a rotary latch is known in which the rocker bar designed as a semicircular member and a perpendicular to the sash level axis is pivotable, whereby it engages in a strike plate. The drive of the rocker bar takes place via a connected to the drive rod transmission device which is mounted longitudinally displaceable with respect to the drive rod longitudinal axis. The power transmission from the transmission device to the rocker bar via a bolt which is guided in a slot of the transmission device. In this known rotary latch, the lever arm between the pivot axis of the rocker bar and the bolt due to the design is relatively low, so that relatively large forces must be introduced into the tilting bar due to the short lever arm to ensure the rotational movement reliable. Therefore, the transmission device is particularly stable and double-sided executed around the tilting block around, for which appropriate space is needed.

The invention has the object of providing a tilt latch closure of the type mentioned in such a way that it can be made more compact on the rocker arm drive side and also has a substantially closed surface finish on the side of the face plate in the retracted state.

To solve this problem, a tilt bar lock according to claim 1 is proposed.

Due to the one-piece connection of the counter-toothing means with the push rod, a more compact design on the tilted-bar drive side is possible since the space required for an additional component is eliminated. This adaptation to the window fitting groove allows installation in a standardized groove with fixed room conditions. Due to the T-shaped design of the Fixierungsarms this has a self-level side surface in the direction of the faceplate, so that in the retracted state of the Fixierungsarms, ie with the wing open, the side surface of Fixierungsarms is flush with the flat surface of the faceplate and thus a in essential closed surface condition is present. As a result, the fitting is better to clean and also gives in the open state of the wing from a consistent overall picture. In addition, it is better suited for window systems with low rebate clearance.

In a further development of the invention is provided according to claim 2 and 3, that the drive means and counter drive means are designed as toothing means and counter-toothing means and that the toothing means have a drive tooth and two enclosing these tooth-like stop edges. As a result, an exact vote on the required tilt angle of about 90 °, whereby the need for attaching additional teeth and the associated design complexity is avoided.

In a further embodiment of the invention is provided according to claim 4, that the counter-toothing means relative to the pure rolling contour of the toothing means have an additional recess portion which serves to ensure a Leerhubes at a window with turn-tilt function for states between a rotational and a Kippbereitschaftsstellung. This results in the following switching states: In the closed state of the window, the tilting bar is extended out of the fitting and performs its closing function. If the fitting is now moved from the closed position into the ready-to-rotate position, the tilting bar is retracted into the fitting and no longer has a closing function. Upon further actuation of the fitting in the tilt-ready position, the tilting bar must now not move further and must remain in the retracted position. The corresponding idle stroke is achieved through the recess area.

In a further development of the invention is provided according to claim 5, 6 and 7, that this is designed to correspond with a further locking element, wherein the closing movements are oriented in opposite directions and wherein the further locking element as a locking bolt with a mushroom-shaped contour with a plate-like head area is executed. By this combination of opposing closing elements an even more effective closing position of the window can be achieved. If the further locking element is designed as a locking pin, then the opposite nature of the closing movements results particularly advantageously without further design effort, since the locking pin moves in the same direction with this due to its direct connection with the push rod, whereas the tilting block due to the pivoting movement about the tilting mirror axis of rotation a reversal of the closing movement direction learns.

In a further embodiment of the invention is provided according to claim 8 and 9, that the faceplate has a rocker box recess portion for receiving the rocker bar in a closed functional position, whose contour is T-shaped and designed to correspond with the contour of the rocker bar, and that for the Tilt rocker two functional positions are provided as a rest position and as a closed position, wherein the rocker bar is located in the rest position substantially within the rocker box recess portion of the faceplate flush with the visible surface, and wherein the rocker bar in functional position with a rocker shaft longitudinal axis substantially perpendicular to the cuff rail longitudinal axis is oriented. This further improves the uniform surface structure and easy cleaning of the fitting.

In a further development of the invention, it is provided according to claim 10 that the striking plate has a first receiving area for the tilting bar and a second receiving area for the closing bolt. Through the integration of the two locking receptacles for the locking pin and the rocker bar in a single component, a reduction of the components to be handled during the assembly process is possible.

Fig. 1 to 6 show a tilt latch closure 10, which is part of an unspecified espagnolette fitting of a window or a door. The espagnolette fitting can be used in a circumferential groove of a window sash of the window and ensures a closure with a fixed frame of the window. The tilt latch closure 10 consists of a cuff rail 12, which is stationary relative to the frame, and a push rod 14 which is mounted longitudinally movable. At the in Fig. 1 illustrated lower end of the push rod 14, a coupling element 16 is provided for coupling to other elements of the espagnolette fitting, at the upper end of the push rod, a further coupling element 18 is provided.

The actual closing operation is ensured by a rocker bar 20 which is rotatably mounted about a tilting mirror pivot axis 22. The rocker pivot axis 22 is oriented perpendicular to a sash frame plane of the window and arranged stationary relative to the face plate 12. The tilting bar 20 is driven by drive means 24 on the tilting bar and corresponding counter drive means 26 on the push rod 14. The drive means 24 and mating drive means 26 are designed as a toothing means, wherein the drive means 24 has a first central drive tooth 28 and two tooth-like abutment edges 30, 32 , The counter drive means 26 consists of recesses 34, 36, 38, in which the drive means 24 can engage in the manner of a rack, wherein the linear movement of the counter drive means is a rotational movement of the rocker bar 20 about the axis of rotation 22.

The tilting bar 20 has a first tilting bar area 42 with a tilting bar shaft 44 and closing means 46, and a second tilting bar area 48 with the drive means 24. The closing means 46 have a T-shaped configuration, the tilting bar shaft 44 forming the base of the T and a fixing arm 52 the two legs of the T are formed. The closing means 46 are designed as Hinterkrallungsvorsprung and can be connected to the frame, in Fig. 6 schematically shown locking plate 50 engage behind a positive fit. To ensure a particularly compact design, the push rod 14 in the region of the tilting bolt 20 has a Kröpfungsbereich 54. The strike plate 50 has a wall 56, the fixing arm 52 in the in the strike plate 50 engages behind the submerged state and thus closes the window.

To further improve the closing function of the window of the tilting mirror lock is combined with another locking element 58. This further locking element 58 is designed as a locking pin 60 with a mushroom-like contour and a plate-like head area. The locking pin 60 is connected to the push rod 14 and thus moves in the opposite direction to the tilting mirror movement direction, due to the reversal of movement by the rotation about the tilting mirror pivot axis 22. By this opposing movement of the closure state is generally more secure against burglary, such as in a break-in attempt by levering Although the window in one direction of the sash plane of one of the closing points is pushed out of the strike plate, the other closure point is pressed into the strike plate.
