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

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

Such devices can be used to open and / or close windows, doors or as ventilation flaps, especially if these are installed in hard-to-reach places, for example also in the case of skylights and the like. In order to ensure a tight closing, in particular also under wind load, the window or the door generally 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 already known from EP 2146032 B1. The known device has for opening and / or closing, as well as for locking a closed state of a locking device for at least partially closing a room opening, for example a window or a door, a drive and a power transmission means which transmits the driving force to the locking device and which is connected to a locking device the closure device can be coupled.

The disadvantage of the known device is the large installation space required, which only allows an arrangement outside visible on the window or a door, due to the size of the drive, but in particular due to a separately arranged deflection device in the housing of the device, which in addition to the guide track of the chain Building on the guide track of the chain at the height of the housing, a separate control groove with one of the guide tracks differing Has control curve. In the event that a tilt and turn window or a door is implemented with the present device, an extension of the housing and the deflection device is required in addition to an increase in stroke, which also has a detrimental effect on the size and costs of the known device.

In addition, no device for a turn-tilt sash or tilt sash of a window or a door with a hybrid drive emerges from the prior art that would allow the switch from automatic opening and closing to manual operation with at least the same switching functions as the automatic ones Functional positions made possible by a manual switching process.

The invention is based on the object of providing a device or method for a turn-tilt sash, tilt sash or turn sash of a window or door of the type mentioned at the outset, which allows motorized tilting into a room-opening tilted position and / or a motorized Approaching the rotary position for manual rotation in an open rotary position allows that is simple and inexpensive to manufacture, can be assembled and adjusted in a simple, fast, 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 method claims 14 and 15. In the present embodiment, the device for opening and / or closing, as well as for locking a closed state of a locking device, at least partially closes a room opening a pivoting and / or tilting window or a door with a sash and a frame, an opening 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 motorized drive. Alternatively, the drive can also be done manually. The possibility of manual Alternatively, for example by means of an operating handle, the purpose of an emergency release should be beneficial.

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

The locking device has a drive rod with locking or locking pins arranged thereon and is arranged on the sash of the window or door. The locking pins engage in the closed state

Locking device lockingly into correspondingly shaped strikers of the window or door, which are fixed to the frame, and thereby form the closed or locked state of the window or door. To achieve a secure adjustability of the opening device, which causes a rotation, a tilting and a secure locking of a turn-tilt sash of a window or a door, the locking device and a base part attached to the frame are arranged on the sash. In the base part, the motor drive device is mounted so as to be coupled to the actuatable force transmission means, which has a connecting member to the wing. The connecting element belonging to the opening device couples and uncouples 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 sash by coupling and uncoupling the connecting rod connecting element arranged at the free end of the power transmission means. For this purpose, the connecting rod connecting element consists of a driver and a hook, which are rotatably connected to one another. In the closed position of the force transmission means and with the locking device of the wing in the locking position to the frame of the connecting rod element having locking pin, the locking pin with the driver and the hook of the connecting rod connecting element is secured encompassing axes. During the motorized adjustment in the direction of the rotary position, the locking pin strikes an inside edge of the hook in an automated manner, the hook automatically rotating towards the driver and a position open on one side in the longitudinal direction of the locking device for the Locking pin releases. When the force transmission means is actuated further, with the hook pivoted open, the locking pin arranged with the locking device and in a recess of the driver assumes the rotary position of the sash by motor. With the motorized retraction in the direction of the closed position, the connecting rod connecting element releases the locking pin and allows the sash to be in the open rotary position. The sash can be operated manually from the turn position to the turn open position and vice versa. In the adjacent position of the sash to the frame and restarting the power transmission means 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 tilt position, the hook strikes a guide element arranged on the sash before the tilt position occurs, whereby an automated connection of the hook with the locking pin is triggered. Secured circumferentially by the driver and the hook of the connecting rod connecting element, the locking pin in the tilted position with the adjacent position of the connecting rod connecting element driving the guide element from the power transmission means, following a guide path in the base part of a circular arc-shaped section, executes an almost 90 ° rotation and follows the sash in the open tilt position. With motorized retraction from the tilt position in the direction of the closed position and in the direction of the power transmission means

Locking position of the wing located locking device of the locking pin, the locking pin is preferably held circumferentially adjacent to an inner edge of the hook in the locked position of the connecting rod connecting element together with the driver.

Preferably, the locking device facing driver and hook of the power transmission means are directly coupled to the locking pin and are automatically driven from a direction of movement of the locking device from the locked closed position of the sash to the frame in the adjacent position of the sash to the frame in a rotating or tilting position and further deflected from the tilted position by a deflection device in a second direction of movement for actuating the power transmission means into an open tilted position of the sash to the frame. To achieve a concealed opening device arranged in a rebate between the frame and the sash of the window or door, the driver and the hook follow the arcuate section of the guide track for the force transmission device when the force transmission means is drawn into the housing of the opening device. With the entry of one linked to the driver

Guide link, preferably a chain link arranged at the end of the chain, of the power transmission means in the circular arc-shaped section, the driver rotates 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 link the driver actuates the locking device upon 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 tilted position, transferred in a free section offset by 90 ° to the direction of movement of the locking device, the connecting rod connecting element being transverse to the direction of extension of the sash is held in a positioning position in the guide element arranged on the sash or the locking device and can be converted from the tilted position with moving into the adjacent position of the sash to the frame into the tilted position with passing through the circular arc-shaped 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 rigid-backed chain, in particular during motorized opening and closing in the tilted position and to achieve an inexpensive and small construction, 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 rigid chain links that transmit tensile and compressive forces. The second free end, which ends in the guideway of the housing and forms the second partial section, is formed with standard chain links by eliminating intermediate plates to enable back rigidity. The flat arrangement of the chain in the second partial section with formed standard chain links, forms a contribution to a concealed installation of the chain and thus at least supports a concealed arrangement of the Opening device in the window or door.

In order to establish a coupling between the power transmission means as a chain and the driver simply and inexpensively, the guide member is hinged to the free end of the power transmission means and forms a fixed connection with the driver, for example a riveted connection. With a non-positive connection of the guide link to the driver and a coupled connection to the free end of a rigid chain link of the chain, the guide link with an arrangement of lubricants, in this embodiment with rollers, forms a leading bearing in the guide track of the base part of the opening device. The movable and sometimes rotatable control of the driver is achieved by moving the chain in connection with the guide link in the guide track in the housing. The shape of the guide link is preferably adapted to a chain link, with the sliding rollers being arranged on the pin links which are in each case distant from one another and which are aligned with the guide track of the chain that forms the groove.

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

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, through the power transmission means of the opening device is achieved that the driver and the Hooks each have a nose which, positively receiving in a recess of the guide element, secures the drive 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 drive 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 rotation inhibition of the driver to the hook can be adjusted by adapting a

Riveted connection or by joining a further component, for example a washer, due to material properties, for example rubber or plastic, and / or shaping, for example a corrugated washer. In addition, the recess has a bevel or a radius on the respective side edges towards the opening. Possible tolerances for a smooth running-in of the

Locking pin in the driver can thus be compensated for easily and inexpensively.

For a secure hold when the opening device passes through a turn and tilt 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 over respective inner edges together with the recess of the driver, the inner edge and the recess in Locking direction of the wing forms the clasping with automatic tumbler for the locking pin. The hook, as a locking member, locks the opening of the recess via a rotating mechanism and holds the locking pin in a secured moving position.

Another 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 with contact of the inner edge on the locking pin. The opening is accordingly generated by an impulse from the drive device as soon as the deployment device moves the locking device out of the locked closed position in the direction of the rotary position or the tilted position. The inner edge of the

Hook on a guide-forming contour around the axis of rotation of the hook at an acute angle, which generates a force component in the opening direction of the wing and the clasping of the connecting rod connecting element through the recess of the driver and the inner edge of the hook with the release of the Locking pin cancels.

Furthermore, the wing can be moved from a locked closed position of the locking device to the frame, after passing through the power transmission means and forced entrainment of the locking device with the locking pin coupled in the direction of the tilt position, with the hook in the swiveled open position and the free position of the locking pin in the recess, by motorized control of the power transmission means Transfer to the guide element up to the tilt position. With the continuation of the power transmission means, the hook runs onto the guide element, overcoming a wedge-shaped shoulder that 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 that is in the open position with an outer contour.

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

Due to the arrangement, the number and the small size of the components of the opening device, the housing can be made L-shaped in cross section over almost the entire length. The flat one predominates

Cross section of the housing. 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. In the method according to the invention, a wing is first brought from the frame to open from a locked closed position to the frame in a rotary position for manual opening in a rotary position or in a tilted position for motorized opening in a tilted position by means of a deployment device. For this purpose, the opening device is coupled to a locking device on the sash and has a base part which is fastened to the frame and on which a motorized drive device actuated power transmission means is stored, which has a connecting member to the wing. The connecting member is a connecting rod connecting element which, by means of the motorized drive device, locks and unlocks the locking device of the sash to the frame. The connecting rod connecting element is arranged at the free end of the power transmission means and consists of a driver arranged on the power transmission means and a hook, which can be coupled to a locking pin arranged on the locking device, resulting in the following steps: Move the

Driving rod connecting element via the power transmission means from a locked closed position of the locking device with automatic opening of the hook into the rotational position of the locking device and releasing the locking pin by moving the open driving rod connecting element back into the closed position of the locking device;

- manual turning of the sash away from the frame into the turn-open position;

- manual rotation of the sash from the rotary open position into the rotary position adjacent to the frame;

- Closing of the sash by motorized displacement of the connecting rod connecting element via the force transmission means with the hook open from the locked closed position beyond the rotary position in the direction of the tilted position and entrainment of the locking pin via the driver with automatic closing of the hook by driving over one arranged on the sash or on the locking device Guide element; - Motorized displacement of the connecting rod connecting element via the

Power transmission means with change of direction in the locked closed position of the locking device or with maintaining the direction and further displacement of the connecting rod connecting element via the power transmission means with the connecting rod connecting element closed in the tilted position

- Motorized tilting of the sash via the power transmission means away from the frame into the space-opening tilt position, into a position of the connecting rod connecting element secured against opening by engagement of the driver and the hook in the recess of the guide element; - Motorized displacement of the connecting rod connecting element via the power transmission means with a change of direction from the secured tilt position into the adjacent tilt position up to the closed position of the sash to the frame and reaching a locked position of the locking device while maintaining the connection of the connecting rod connecting element with the locking pin.

The method according to the invention for opening and closing a rotatable and tiltable sash of a window or door is carried out by means of an opening device, with a locking device on the sash and a base part attached to the frame, on which a power transmission means actuated by a motor drive device is mounted, which is a connecting member to the wing, wherein the connecting member is a connecting rod connecting element, wherein the locking device can be locked and unlocked by means of the motorized drive device, wherein the connecting rod connecting element is arranged at the free end of the power transmission means and consists of a driver arranged on the power transmission means and a hook which can be coupled to a locking pin arranged on the locking device, so that the wing can be actuated by motorized actuation of the opening device and one arranged on the wing is driven

The locking device can be transferred from the closed position into an open tilted position of the sash, so that the sash can be transferred from the locked closed position into a rotary position for manual operation into the rotary open position of the sash by motorized actuation of the opening device and driving the locking device arranged on the sash the space in the open tilted position or in the rotary position can be transferred into the locked closed position by actuating the opening device with a motor. To avoid unwanted vibrations, which can lead to damage and unnecessary noise, the motor and a worm, which forms the transmission to the gearbox, are housed in a separate vibration-damping housing. Vibration-damping components with the motor and the worm can also be integrated directly into the housing with the gearbox and the control system. The device in the housing preferably comprises a frictional connection, for example by means of a threaded pin or a form-fitting connection, for example in the form of a spring element, which, as an emergency release device, moves the motor from the transmission into a disengaged position in order to interrupt the frictional connection between the motor and the transmission.

The stroke of the locking device 2 of the window or of the door 3 specifies the motorized adjustment path of the opening device 1 from the locked closed position according to FIG. 5 to the tilted position according to FIG. 9. After the motor-driven 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 opened tilting position without further adjustment of the locking pin 15.

The back-stiff chain of the power transmission means 8 is divided into two sections for motorized opening and closing from the tilt position into the open tilt position of the sash 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 kink-resistant chain links. The second free end 33, which ends in the guide track 20 of the housing 22 and forms the second partial section, is formed with standard chain links by eliminating intermediate plates to enable the back stiffness. The flat arrangement of the chain in the second partial section with standard chain links formed a contribution to a concealed installation of the chain and thus contribute at least to a concealed arrangement of the opening device 1 in the window or door 3 (see Fig. 5).

The guide member 23 is, for example according to FIG. 5, with the driver 12 a fixed connection, for example a riveted connection. With a non-positive connection of the guide link 23 on the driver 12 and a coupled connection at the free end 11 of one of the rigid back chain links of the chain 8, the guide link 23 with an arrangement of sliding means, in this embodiment with sliding rollers, forms a leading bearing in the guide track 20 and sometimes rotatable control of the driver 12 is achieved with the movement of the chain 8 in connection with the guide member 23 in the guide track 20 in the housing 22 of the opening device 1. Also evident from FIG. 5, the shape of the guide link 23 is adapted to a chain link remote pin links the rollers are arranged, which are aligned with the groove-forming guide track 20 of the chain.

According to Fig. 4, the driver 12 and the hook 13 are flat. For a long service life and guaranteed guarantee of switching cycles, the driver 12 and the hook 13 are made of a metal, cast or plastic. The flat sides of the driver 12 and the hook 13 even allow movement in a free field of operation of the window or door 3, outside of the housing 22 in the frame 5 and the opposite wing 4 with the locking device 2, a perfectly material-friendly operation.

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 noses 25,

26 are in the clasping position of the connecting rod connecting element 10 with the locking pin 15 precisely matched with a recess 27 of the guide element 18. In a 90 ° pivoted position transverse to the direction of adjustment of the locking device 2 and encompassing engagement of the drive rod connecting element 10 with the locking pin 15, the lugs 25, 26 of FIG. 11 are in a form-fitting connection with the recess 27 of the guide element 18. The absence of unwanted movement the

Opening device 1 during the travel in the direction of the open tilted position according to FIG. 12 and back, is activated 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 reached. With the position of the driver 12 and the hook 13 for the motorized extension and retraction of the wing 4 in a space-opening tilted position according to FIGS. 1, 2 and 12 or a locked closed position according to FIG. 5, the back stiffness is held in a stable and tensioned manner of the chain 8 during the exit of the chain 8 from the housing 22 according to FIG. 11, likewise through the ones arranged on the driver 12 and hook 13

Lugs 25, 26 reached, which hold the force transmission means 8, in particular the chain, permanently in a position that is rigid in the back.

For functionally secure control when opening and closing the connecting rod connecting element 10, in particular during the adjustment of the locked one 5 to the rotary position according to FIG. 7 and back, the driver 12 and the hook 13 are connected to one another in a rotationally inhibited manner by friction.

The rotation inhibition of the driver 12 to the hook 13 can be brought about by adapting the riveted connection at the pivot point of the axis of rotation 28 or by joining further components, for example a disk, due to material properties and / or shape.

To compensate for tolerances, the recess 17 of the driver 12 has a bevel or a radius on respective side edges 34, 35 of a one-sided, U-shaped opening. An engagement of the locking pin 15 from the manually openable rotational position of the wing 3 in the direction of the form-fitting position with connection of the driver 12 to the locking pin 15 according to FIG. 7 is thus functionally relieved. When the opening device 1 passes from the locked closed position of the sash 4 to the frame 5 of the window or the door 3 according to FIG. 5 into the rotating position according to FIG. 7 or the tilting position according to FIG. 9 and vice versa, the hook 13 clasps over respective inner edges 16, 21 together with the recess 17 of the driver

12 the locking pin 15. The inner edge 21 and the recess 17 together in the locking direction of the wing 4 according to FIG. 13 form the clasping with automatic tumbler for the locking pin 15. The hook locks

13 as a locking member via a rotating mechanism, the opening of the recess 17 and holds the locking pin 15 in a secured drive device 7 movable position.

In order to achieve an automatic triggering of the hook 13 for one-sided opening of the driver 12 of the connecting rod connecting element 10 according to FIG. 6 and the locking pin 15 thus detached from the deployment device 1 and decoupled from the drive device 7 the possibility for a free extension into a free field of operation and to allow manual rotation of the sash 4, the inner edge 16 of the hook 13 is designed with a contour which, with motorized actuation of the opening device 1 in the direction of the rotating or tilting position, is subjected to pressure by the locking pin 15 and via the axis of rotation 28 to the Driver 12 automatically swings out the locking pin 15 on one side releases.

Furthermore, the wing 4 can be moved from a locked closed position of the locking device 2 to the frame 5 according to FIG. 5, after passing through the force transmission means 8 and forced entrainment of the locking device 2 with the locking pin 15 coupled in the direction of the tilt position, with the hook 13 in the swiveled-out, open position and free position of the locking pin 15 in the recess 17 according to FIG. 6 and FIG. 7, by motorized control of the power transmission means 8 until before the tilting position, transferring to the guide element 18 according to FIG. 9. According to FIG. 9, the hook 13 runs onto the guide element 18 in a motor-controlled manner, overcoming a wedge-shaped shoulder 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 also includes the hook 13 in the open position Creation of an outer contour closes automatically step by step.

For use of the tilt and turn window or door 3 with right-hand or left-hand opening, the guide element 18 is designed symmetrically, 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 one
