EP4041975B1 - Opening device for a turn-tilt sash of a window or door - Google Patents

Description

The invention relates to a deployment device for opening and closing, and for turning and/or tilting and locking a closed state of a locking device, for at least partially closing a room opening, a rotating and/or tilting window or a door, according to the preamble of the claim 1.

Devices of this type can be used to open and/or close windows, doors or as ventilation flaps, particularly if they are installed in places that are difficult to access, for example also in the case of skylights and the like. In order to ensure tight closing, in particular under wind load, the window or the door usually has a locking device, by means of which it can be locked in the closed state. A separate drive device can be provided for actuating the locking device.

A device with a locking device of this type is by the EP 2146032 B1 already known. For opening and/or closing and for locking a closed state of a closure device for at least partially closing a room opening, for example a window or a door, the known device has a drive and a force transmission means which transmits the drive force to the closure device and which is connected to a locking device the closure device can be coupled.

A disadvantage of the known device is the large installation space required, which only allows an arrangement outside of the window or a door, due to the size of the drive, but in particular due to a deflection device arranged separately in the housing of the device, which is additionally arranged next to the guideway of the chain A separate control groove with one that deviates from the guideway builds up above the guideway of the chain at the height of the housing Has control curve. If a turn and tilt window or a door is implemented with the present device, the housing and the deflection device must be lengthened in addition to an increase in stroke, which also has a disadvantageous effect on the size and costs of the known device.

In addition, the prior art described above does not provide any device for a turn-tilt sash or tilt sash of a window or a door with a hybrid drive that allows switching from automatic opening and closing to manual operation with at least the same switching functions of the automatic functional settings made possible by a manual switching process.

Next will be on the EP 3 221 165 A1 referred to, which is an opening device for a turn-tilt sash of a window or a door, for motorized starting by a drive device in a subsequently manually actuated rotary position or manually openable tilt position with automatic opening and closing or separating and coupling the drive rod connecting element. For this purpose, when the scissor stays are in the closed position and the locking device is in the locking position, the connecting rod connecting element can be automatically separated from a connecting rod locking pin as a connecting rod element during the motorized adjustment in the direction of the rotary position with the pin striking an inner edge of the hook. When the hook is swung out, the scissor-stay motor assumes the closed position and thus releases the rotary position of the pin. According to this exemplary embodiment, the pin of the locking device is located in a freely operable field in the rotary function position, so that the wing can be manually transferred into an open rotary position, detached from the drive device. When the scissor-stay stays open again from the closed position with the hook open in the direction of the pin arranged in the rotary position and when the pin engages in the recess of the holding arm in the rotary position, the connection of the hook to the pin is automated by releasing the spring element from a permanently tensioned position initiated a spring tensioner arranged on the base part in a tensioned position with the hook, which is acted upon by means of pivoting of the hook spring force connecting causes. With motorized retraction from the rotary position in the direction of the closed position and the locking device of the pin in the direction of the locking position, the pin is held in contact with an inner edge of the hook, with the spring element relaxing the hook and entering into a permanently tensioned position with the spring tensioner.

The object of the invention is to provide a device or method for a turn-tilt sash, tilt sash or turn sash of a window or a door of the type mentioned at the outset, which allows motorized tilting into a space-opening tilted position and/or a motorized Approaching the rotational position for manual turning into an open rotational position allows the manufacturing process to be simple and inexpensive, can be installed and adjusted in a simple, quick, safe and precise manner and which avoids the aforementioned disadvantages in terms of size.

The object is achieved with the means of the characterizing part of claim 1 and the corresponding method claim 14.

In the present embodiment, the device for opening and/or closing and locking a locking device in a closed state, for at least partially closing a room opening of a turn and/or tilting window or a door with a sash and a frame, has a raising device with a drive device and a force transmission means which transmits the drive force to the locking device and which can be coupled to a locking device by means of at least one locking pin of the locking device.

The drive can have an electric motor or other motor drive.

Alternatively, but not within the scope of the invention, the drive can also be manual. The possibility of a manual alternative, for example by means of an actuating handle, should be conducive to the purpose of an emergency release.

The force transmission means preferably transmits both tensile and compressive forces. For this purpose, the power transmission means is formed at least in sections by a kink-resistant chain.

The locking device has a connecting rod with locking or locking pins arranged thereon and is arranged on the sash of the window or door. In the closed state of the locking device, the locking pins engage in a locking manner in correspondingly shaped locking pieces of the window or door fixed to the frame and thereby form the closed or locked state of the window or door.

In order to achieve reliable adjustability of the opening device, which causes rotation, tilting and secure locking of a tilt and turn sash of a window or door, the locking device and a base part fastened to the frame are arranged on the sash. In the base part, the motor drive device is mounted in a coupling manner with the actuable force transmission means, which has a connecting member to the wing. The connecting member belonging to the deployment device couples and decouples the locking device and forms a connecting rod connecting element. The motor-operated opening device mounted on the frame thus automatically locks and unlocks the locking device on the wing by coupling and decoupling the drive rod connecting element arranged at the free end of the force transmission means. For this purpose, the drive rod connecting element consists of a driver and a hook, which are rotatably connected to one another. In the closed position located power transmission means and located in the locking position locking device of the wing to the frame of the connecting rod element having locking pin, the locking pin is secured with the driver and the hook of the connecting rod connecting element axles encompassing. During the motorized adjustment in the direction of the rotary position, the locking pin advantageously automatically strikes an inner edge of the hook, the hook automatically twisting towards the driver and releasing a position open on one side in the longitudinal direction of the locking device for the locking pin. Upon further actuation of the power transmission means, with the hook pivoted open, the locking pin arranged with the locking device and in a recess of the driver motor-drivenly assumes the rotary position of the leaf. With motorized retraction in the direction of the closed position, the connecting rod connecting element releases the locking pin and allows the sash to open in a pivoting position. From the turning position to the turning opening position and vice versa, the wing can be operated manually. When the sash is in contact with the frame and the force transmission means is moved again from the closed position with the hook automatically opened and with the locking pin engaging in the recess of the driver in the direction of the tilted position, the hook strikes a guide element arranged on the sash before the tilted position is reached, whereby an automated connection of the hook with the locking pin is triggered. Circumferentially secured by the driver and the hook of the connecting rod connecting element, the locking pin, in the tilted position with the connecting rod connecting element in the abutting position on the guide element, is driven by the force transmission means and follows a guideway by means of a circular arc-shaped section in the base part, rotating by almost 90° and follows the sash in the open tilt position. With motorized retraction from the tilted position in the direction of the closed position and the locking device of the locking pin in the direction of the locking position of the wing, the locking pin is held circumferentially in contact with an inner edge of the hook in the locked position of the connecting rod connecting element together with the driver.

Preferably, the driver and hook of the force transmission means facing the locking device are coupled directly to the locking pin and are automatically transferred in a drive-bound manner from a direction of movement of the locking device starting from the locked closed position of the sash to the frame when the sash is in contact with the frame and into a rotary or tilted position further deflected from the tilted position by a deflection device in a second direction of movement for actuating the force transmission means in an open tilted position of the wing to the frame.

In order to achieve a concealed opening device arranged in a rebate space between the frame and the sash of the window or door, the driver and the hook follow the arcuate section of the guideway for the force transmission means as the force transmission means is drawn into the housing of the opening device. When a guide link articulated on the driver, preferably a chain link arranged at the end of the chain, of the force transmission means enters the arcuate section, the twists Driver together with the hook at an angle of almost 90° around the axis of the locking pin located in the driver and hook, with further retraction of the guide member, the driver actuates the locking device with further engagement of the locking pin.

The power transmission means, designed as a chain, is extended out of the housing with the driver and the hook of the connecting rod connecting element when the sash is in the motor-driven open tilt position, in a free section offset by 90° to the direction of movement of the locking device, with the connecting rod connecting element being transverse to the extension direction of the sash is held in position in the guide element arranged on the sash or the locking device and can be transferred from the tilted position with retraction into the position in which the sash rests against the frame into the tilted position with passage through the arcuate section in the housing in a linear movement parallel to the direction of movement of the locking device .

In order to avoid buckling of the back-rigid chain, in particular during motorized opening and closing in the tilted position and to achieve an inexpensive and small design, the chain is advantageously divided into two sections. The first section has the driver and the hook at its first free end and is designed with buckling-resistant chain links that transmit tensile and compressive forces. The second free end, which ends in the guide track of the housing and forms the second section, is formed with standard chain links by eliminating intermediate straps to allow back rigidity. The flat arrangement of the chain in the second section with trained standard chain links makes a contribution to a concealed installation of the chain and thus contributes at least to a concealed arrangement of the opening device in the window or the door.

In order to produce a coupling between the force transmission means as a chain and the driver simply and inexpensively, the guide member is articulated at the free end of the force transmission means, which enters into a fixed connection, for example a riveted connection, with the driver. With a non-positive connection of the guide link on the driver and coupled connection at the free end of a chain link of the chain with a stiff back, the guide link also forms Arrangement of sliding means, in this embodiment with sliding rollers, a leading bearing in the guideway of the base part of the display device. The movable and sometimes rotatable control of the driver is achieved with the movement of the chain in connection with the guide link in the guideway in the housing.

Preferably, the shape of the guide link is adapted to that of a chain link, with the slide rollers being arranged on the bolt links that are spaced apart from one another and aligned with the groove-forming guide track of the chain.

Also contributing to a concealed arrangement of the opening device in the rebate of the window or door are the drivers and hooks, which are designed as flat metal, cast iron or plastic and can be moved together outside the housing. The flat configuration of the tang and the hook extend outside the housing between the housing and the opposite wing, even when moving in a free space of one flat side.

A secure hold during the adjustment of the sash to the frame from an adjacent tilted position of the sash to the frame to the open tilted position of the sash and returning to the adjacent tilted position of the sash to the frame is achieved by the power transmission means of the deployment device in that the driver and the Hooks each have a lug which, positively receiving in a recess of the guide element, secures the connecting rod connecting element and the locking pin in the locked position against displacement in the longitudinal direction of the movement of the locking device and against unintentional opening of the connecting rod connecting element.

A further advantageous embodiment results from the fact that the driver and the hook are connected to one another in a rotationally inhibited manner by friction, the open recess of the driver is U-shaped and extends lengthwise in the direction of movement of the guide member of the guide track. The driver can be prevented from rotating relative to the hook by adapting a rivet connection or by adding another component, for example a washer, due to material properties, for example rubber or plastic, and/or shaping, for example a corrugated washer. Besides that the recess has a chamfer or a radius on the respective side edges towards the opening. Possible tolerances for a smooth run-in of the locking pin into the driver can thus be compensated for easily and inexpensively.

For a secure hold with the opening device running through a turning and tilting position from the locked closed position of the sash to the frame of the window or door and vice versa, the hook clasps the locking pin via the respective inner edges together with the recess of the driver, with the inner edge and the recess in Locking direction of the wing forms the clasp with automatic locking for the locking pin. The hook, as a blocking element, locks the opening of the recess via a rotary mechanism and keeps the locking pin movable in a secured drive device position.

A further advantageous handling results from the position of the inner edge of the hook, which is designed as a trigger for automatically pivoting opening of the hook due to the contour of the locking pin and releases the U-shaped recess when the inner edge contacts the locking pin. Accordingly, the opening is generated by an impulse from the drive device as soon as the opening device moves the locking device from the locked closed position in the direction of the rotary position or tilt position. For this purpose, the inner edge of the hook has a contour forming a guide around the axis of rotation of the hook at an acute angle, which generates a force component in the opening direction of the sash and releases the gripping of the drive rod connecting element by the recess of the driver and the inner edge of the hook when the locking pin is released .

Furthermore, the sash can be moved from a locked closed position of the locking device to the frame, after passing through the force transmission means and forced entrainment of the locking device with coupled locking pin in the direction of the tilt position, with the hook in the pivoted open position and the locking pin in the free position in the recess, by motor control of the force transmission means transfer to the guide element up to the tilted position. With the continuation of By means of power transmission means, the hook runs onto the guide element, thereby overcoming a wedge-shaped shoulder which extends from the free end of the guide element in the direction of the central axis to the recess and gradually automatically closes the hook located in the open position with an outer contour.

Preferably, the guide element is designed symmetrically so that the sash of a window or door can be used on the right or left, with the step being formed on both sides of the guide element. The guide element made of a plastic part proves to be simple and economical to manufacture. In addition, an easily mountable, maintenance-free deployment device with good sliding properties can be achieved.

Due to the arrangement, the number and the small size of the components of the deployment device, the housing can be designed with an L-shaped cross section over almost the entire length. The flat cross-sectional part of the housing in particular predominates. A concealed arrangement of the opening device in the rebate space of the window or door can thus be realized with the object according to the invention.

On the frame 5, there is a base part 6 in a position for receiving the same shown bag mounted concealed. The deployment device 1 is preferably arranged on the upper horizontal beam 31 between the leaf 4 and the frame 5 . The wing 4 and the frame 5 are opposite each other with respect to horizontal and vertical bars with rebate surfaces and have locking elements on the locking device 2 that engage behind each other, of which - not shown - one is on the frame 5 and the other on the wing 4 is attached. The locking elements of the locking device 2 can be moved relative to one another and can be brought into engagement with one another in a locking position and locked closed position of the sash 4 with respect to the frame 5 by means of motorized and likewise possible manual operation.

The Figures 1 to 13 and the description describe, for the sake of simplicity, a window or door 3 that can be operated by motor via an opening device 1 for a room-opening tilted position and a motorized travel path of the opening device 1 in a rotary position for manual turning into a room-opening position or rotary opening position of the sash 4 to the frame 5.

The manual actuation by means of the actuation handle, not shown, for the locking device 2, which, like the motorized adjustment, also enables the connection and disconnection between the locking device 2 and the deployment device 1, can be used for a possible emergency unlocking.

In the Figures 1 to 4 to recognize, the locking device 2 Espagnolette element 14 with locking or locking pin 15 arranged thereon and is arranged on the wing 4 of the window or the door 3 . When the locking device 2 is in the closed state, the locking pins 15 engage in a locking manner in correspondingly shaped locking pieces (not shown) of the window or the door 3 that are fastened to the frame 5 and thereby form the closed state of the window or the door 3.

To adjust the opening device 1 after Figures 1 to 4 , which requires manual rotary opening after the locking device 2 has been moved into the rotary position by a motor and released from the opening device 1 by a motor 8 allowed, as well as a motorized tilting after motorized starting of the locking device 2 in the tilted position 11 and subsequent motorized deployment into the open tilted position of the sash 4 12 enabled by the opening device 1 and a secure locking of the turn-tilt sash 4 of the window or a door 3 after figure 5 causes, the locking device 2 and a base part 6 fastened to the frame 5 are arranged on the wing 4 . This is in the base part 6 after 3 a motor drive device 7 with the in 1 and 2 shown operable power transmission means 8 mounted coupling that a connecting member 9 to the wing 4 has. The connecting member 9 belonging to the display device 1 couples and decouples the locking device 2 and forms a connecting rod connecting element 10 1 mounted motor-operated opening device 1 automatically locks and unlocks the locking device 2 on the wing 4 by coupling and decoupling a connecting rod connecting element 10 arranged at the free end 11 of the force transmission means 8. For this purpose, the connecting rod connecting element 10 consists according to Figures 5 to 13 a driver 12 and a hook 13 which are rotatably connected to each other.

When the power transmission means 8 is in the closed position and when the locking device 2 of the leaf 4 is in the locking position, the locking pin 15 with the connecting rod element 14 moves towards the frame 5 Figures 3 to 5 , At least one locking pin 15 with the driver 12 and the hook 13 of the drive rod connecting element 10 is after figure 5 Axles secured. A so-called mushroom head pin is preferably used as the locking pin 15, which connects the drive rod connecting element 10 additionally protects against unintentional loosening in the axial direction.

During the initially motorized displacement of the locking device 2 via the raising device 1 from the locking position of the locking device 2 of the wing 4 to the frame 5 in the direction of the rotary position 6 , the locking pin 15 automatically strikes an inner edge 16 of the hook 13 in an advantageous manner, with the hook 13 twisting to the driver 12 and a position open on one side with opening of a recess 17 of the driver 12 in the longitudinal direction and displacement direction according to arrow 32 of the locking device 2 for the locking pin 15 releases.

With further motorized displacement of the force transmission means 8, with the hook 13 being pivoted open, the locking pin 15 arranged with the locking device 2 and in a recess 17 of the driver 12 retracts 7 the rotational position of the wing 4. With motorized retraction in the direction of the closed position 8 , the connecting rod connecting element 10 releases the locking pin 15 and allows the wing 4 to rotate in the open position. The drive rod connecting element 10 with the driver 12 and the hook 13 is in an open state.

When the locking pin 15 is in the rotational position of the locking device 2 and is motor-decoupled from the opening device 1, the leaf 4 can be manually operated away from the frame 5 into the rotational opening position and vice versa.

In the applied rotational position of the leaf 3 and renewed motorized starting of the power transmission means 8 from the closed position with the hook 13 automatically opened and with engagement of the locking pin 15 in the recess 17 of the driver 12 in the direction of the tilted position 8 , hits the hook 13 before entering the tilted position 7 to a guide element 18 arranged on the wing 4, as a result of which an automated connection of the hook 13 to the locking pin 15 takes place continuously when an outer contour of the hook 13 rests on the guide element 18. From the driver 12 and the hook 13 of the drive rod connecting element 10 after 9 extensively secured, the locking pin 15 leads into the tilted position with the fitting position of the connecting rod connecting element 10 on the guide element 18 driven by a motor from the power transmission means 8 by means of a circular arc-shaped section 19 in the base part 6 following a guideway 20, rotates almost 90° and follows the leaf 4 with removal from the frame 5 into the open tilted position 11 .

During the motorized retraction from the open tilted position of the wing 4 after 12 into the tilt position 11 with adjacent position of the wing 4 to the frame 5 in the direction of the closed position located force transmission means 8 and in the direction of the locking position of the wing 4 located locking device 2 of the locking pin 15 after figure 5 , the locking pin 15 is held circumferentially adjacent to an inner edge 21 of the hook 13 in the locked position of the drive rod connecting element 10 together with the driver 12 (for this 13 ). The inner edge 21 thus closes the opening of the recess 17 of the driver 12. Due to the shaping contour of the inner edge 21 and a rotation restriction formed between the driver 12 and the hook 13, the drive rod connecting element 10 remains within the required adjustment path of the deployment device 1 with the Locking device 2 closed.

From the Figures 5 to 13 As can be seen, the driver 12 and hook 13 of the force transmission means 8 facing the locking device 2 are coupled directly to the locking pin 15 and are moved from a direction of movement of the locking device 2, starting from the locked closed position of the sash 4 to the frame 5 in the abutting position of the sash 4 to the frame 5 after figure 5 into a turning position 7 or in a tilted position 8 automatically transferred to the drive and further out of the tilted position by a deflection device in a second direction of movement for actuating the force transmission means 8 11 into an open tilt position 12 of the wing 4 to the frame 5 deflected.

To achieve a concealed lying in a rebate between the frame 5 and the sash 4 of the window or the door 3 arranged opening device 1 after 1 , Follows the driver 12 and the hook 13 lying one above the other, with retraction of the power transmission means 8 in the housing 22 of the deployment device 1, the arcuate section 19 of the guideway 20 for the power transmission means 8. On the last chain link to the free end of the power transmission means 8 is after Figures 5 to 13 on the driver 12 of the drive rod connecting element 10, a guide member 23 is arranged, which the arcuate portion 19 after 10 follows, with the driver 12 rotated together with the hook 13 at an angle of almost 90 ° about the axis 24 of the locking pin 15 located in the driver 12 and hook 13 . With further retraction of the guide member 23 into the housing 22 of the deployment device 1, the driver 12 continues to engage in the locking pin 15, whereby the locking device 2 is actuated.

After 12 the power transmission means 8, designed as a chain, is transferred with the driver 12 and the hook 13 of the drive rod connecting element 10 extended out of the housing 22 of the base part 6 in a free section offset by 90° to the direction of movement of the locking device 2 when the leaf 4 is in the motor-driven open tilted position. In the extended tilted position 12 , the opening device 1 is in an extended end position of the musculoskeletal system of the power transmission means 8. In the extension movement of the opening device 1 from the tilted position to the open tilted position or vice versa 11 and 12 , The drive rod connecting element 10 is held positioned aligned transversely to the extension direction of the wing 4 or in the direction of arrow 31 in the arranged on the wing 4 or the locking device 2 guide element 18 position. After motorized transfer to the tilt position 9 , The drive rod connecting element 10 with a parallel course in the guideway 20 can be linearly moved in the direction of movement of the locking device 2 of the window or the door 3 lying concealed between the housing 22 and the locking device 2 into the locked closed position figure 5 move. The stroke of the locking device 2 of the window or the door 3 gives way to the motorized adjustment path of the opening device 1 from the locked closed position figure 5 up to the tilt position 9 before. After the motorized tilting position of the opening device 1 and the tilting position of the locking device 2, which also represents the end of the stroke of the locking device 2 and thus of the locking pin 15, the motorized movement of the opening device 1 follows via the power transmission means 8 of the chain in the direction of the open tilted position without further adjustment of locking pin 15.

The rigid back chain of the power transmission means 8 is divided into two sections for motorized opening and closing from the tilted position to the open tilted position of the wing 4 to the frame 5 . The first section is formed at its first free end 11 of the connecting rod connecting element 10 with tensile and compressive forces transmitting buckling-resistant chain links. The second free end 33, which ends in the guideway 20 of the housing 22 and forms the second section, is formed by eliminating intermediate links to allow back rigidity with standard chain links. The flat arrangement of the chain in the second section with trained standard chain links makes a contribution to a concealed installation of the chain and thus contributes at least to a concealed arrangement of the opening device 1 in the window or the door 3 (on this figure 5 ).

The guide member 23 goes, for example figure 5 , With the driver 12 a fixed connection, for example a rivet connection. With a non-positive connection of the guide link 23 to the driver 12 and a coupled connection to the free end 11 of one of the rigid-backed chain links of the chain 8, the guide link 23 forms a leading bearing in the guideway 20 with an arrangement of sliding means, in this exemplary embodiment with sliding rollers and sometimes rotatable control of the driver 12, is achieved with the movement of the chain 8 in connection with the guide link 23 in the guide track 20 in the housing 22 of the display device 1. Also evident from the figure 5 , the shape of the guide link 23 is adapted to that of a chain link, with the slide rollers being arranged on the bolt links which are in each case spaced apart from one another and aligned with the groove-forming guideway 20 of the chain.

After 4 the driver 12 and the hook 13 are flat. For a long service life and a guaranteed guarantee of switching cycles, the driver 12 and the hook 13 are made of metal, cast or plastic. The flat sides of the driver 12 and the hook 13 even allow movement in a free field of activity of the window or door 3, outside the housing 22 in the frame 5 and the opposite wing 4 with the locking device 2 an operation that is gentle on the material.

The driver 12 and the hook 13 have a nose 25, 26 at the respective free ends, which protrude in the direction of the guide element 18. The lugs 25, 26 are in the clasping position of the drive rod connecting element 10 with the locking pin 15 with a precise fit with a recess 27 of the guide element 18 matched to one another. In a 90 ° pivoted position transverse to the direction of adjustment of the locking device 2 and enclosing engagement of the drive rod connecting element 10 with the locking pin 15, the lugs 25, 26 are located after 11 in a positive connection with the recess 27 of the guide element 18. The absence of an unwanted movement of the deployment device 1 during the travel in the direction of the open tilted position 12 and back is achieved by the engagement of the respective lugs 25, 26 in the recess 27 of the guide element 18 with simultaneous positive and non-positive engagement of the guide pin 15 in the drive rod connecting element 10 and the locking device 2. With the position of the driver 12 and the hook 13 for motorized extension and retraction of the wing 4 in a space-opening tilted position Figures 1, 2 and 12 or a locked closure position figure 5 , a stable and tension-controlled hold of the back stiffness of the chain 8 during the emergence of the chain 8 from the housing 22 is determined 11 also achieved by the lugs 25, 26 arranged on the driver 12 and the hook 13, which hold the force transmission means 8, in particular the chain, permanently in a position with a stiff back.

For functionally reliable control when opening and closing the drive rod connecting element 10, in particular during the adjustment from the locked closed position figure 5 into the turning position 7 and back, the driver 12 and the hook 13 are connected to each other in a rotationally inhibited manner by friction. The driver 12 can be prevented from rotating relative to the hook 13 by adjusting the riveted connection at the pivot point of the axis of rotation 28 or by joining other components, for example a disk, due to material properties and/or shape.

To compensate for tolerances, the recess 17 of the driver 12 on the respective side edges 34, 35 of a one-sided, U-shaped opening has a chamfer or a radius. An engagement of the locking pin 15 from the after 8 manually openable rotational position of the wing 3 in the direction of positive position with connection of the driver 12 to the locking pin 15 after 7 , is thus functionally relieved.

By passing through the opening device 1 from the locked closed position of the wing 4 to the frame 5 of the window or the door 3 figure 5 into the turning position 7 or tilt position after 9 and vice versa, the hook 13 clasps the locking pin 15 via respective inner edges 16, 21 together with the recess 17 of the driver 12. The inner edge 21 and the recess 17 together form the leaf 4 in the locking direction 13 the clasping with automatic locking for the locking pin 15. The hook 13 as a locking member locks the opening of the recess 17 via a rotary mechanism and holds the locking pin 15 in a secured drive device 7 movable position.

To an automatic triggering of the hook 13 for one-sided opening of the driver 12 of the drive rod connecting element 10 after 6 and to allow the locking pin 15, detached from the deployment device 1 and decoupled from the drive device 7, to freely extend into a free field of activity and to manually turn the leaf 4, the inner edge 16 of the hook 13 is designed with a contour , which is subjected to pressure by the locking pin 15 with motorized actuation of the opening device 1 in the direction of the rotating or tilting position and automatically pivoting out via the axis of rotation 28 to the driver 12 to release the locking pin 15 on one side.

Furthermore, the leaf 4 can be moved from a locked closed position of the locking device 2 to the frame 5 figure 5 , after passing through the power transmission means 8 and forced entrainment of the locking device 2 with the coupled locking pin 15 in the direction of the tilted position, with the hook 13 in the pivoted open position and the locking pin 15 in the free position in the recess 17 6 and 7 , passing over to the guide element 18 by motor control of the force transmission means 8 up to the tilted position 9 convict. The hook 13 runs after 9 motor-controlled onto the guide element 18, thereby overcoming a wedge-shaped step 30, which extends from the free end 29 in the direction of the central axis of the guide element 18 to the recess 27 and automatically closes the hook 13 in the open position step by step when an outer contour is applied.

For use of the tilt and turn window or door 3 with right-hand or left-hand opening, the guide element 18 is formed symmetrically, with the shoulder 30 being formed on both sides of the guide element 18 . At the same time, the respective paragraphs 30 together with the recess 17 form an undercut for hooking the lugs 25, 26 of the driver 12 and the hook 13 for an adequate hold against displacement for the connecting rod connecting element 10 11 and 12 .

The housing 22 follows the trend of a window or a door 3 with ever decreasing profile thickness of the leaf 4 and the frame 5 and to achieve a concealed arrangement of the opening device 1 2 and 3 L-shaped in cross section over almost the entire length.
