Description

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 through the EP 2146032 B1 already become known. 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 has a separate control groove with a control curve that differs from the guide track at the height of the housing above the guide track of the chain. 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, the prior art does not provide any device for a turn-tilt sash or a tilt sash of a window or door with a hybrid drive 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 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, for at least partially closing a room opening of a turn and / or tilt window or a door with a sash and a frame, has 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 a manual alternative, for example by means of an operating handle, should be beneficial to the purpose of an emergency release.

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. In the closed state of the locking device, the locking pins engage in 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 safe adjustability of the opening device, which allows turning, tilting and secure locking of a turn-tilt Causes sash of a window or 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 automatically against an inner edge of the hook, the hook automatically rotating towards the driver and releasing a position open on one side in the longitudinal direction of the locking device for the locking pin. 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 track in the base part, executes an almost 90 ° rotation and follows the sash into the open tilt position. With motorized retraction from the tilt 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 sash, the locking pin is preferably held circumferentially in the locked position of the connecting rod connecting element together with the driver, lying against an inner edge of the hook.

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 force transmission means into an open tilted position of the sash relative 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 circular arc-shaped section of the guide track for the force transmission device when the force transmission means is drawn into the housing of the opening device. When a guide link articulated to the driver, preferably a chain link arranged at the end of the chain, of the power transmission means enters 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, wherein, 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 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 retraction 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 section with standard chain links is a contribution to a concealed installation of the chain and thus at least contributes to 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, secure 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 rotation inhibition of the driver to the hook can be brought about by adapting a riveted connection or by joining a further component, for example a washer, based on 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 the locking pin to run smoothly into the driver can thus be compensated for in a simple and cost-effective manner.

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. For this purpose, the inner edge of the hook has a contour that forms a guide around the axis of rotation of the hook at an acute angle, which in the opening direction of the Wing generates a force component and removes 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.

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 part of the cross-section of the housing 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.

During the motorized retraction from the opened tilt position of the sash 4th to 12th into the tilt position 11 with adjacent position of the wing 4th to the frame 5 force transmission means located in the direction of the closed position 8th and in the direction of the locking position of the wing 4th located locking device 2 of the locking pin 15th to 5 , becomes the locking pin 15th on an inside edge 21 of the hook 13th lying in the locked position of the connecting rod connecting element 10 together with the driver 12th kept extensively (see 13th ). The inside edge 21 thus closes the opening of the recess 17th of the driver 12th . Due to the shaping contour of the inner edge 21 and through a rotation lock formed between the driver 12th and the hook 13th , remains the connecting rod connecting element 10 within the required adjustment range of the opening device 1 with the locking device 2 closed.

From the 5 to 13th can be seen is the locking device 2 facing driver 12th and hook 13th of the power transmission means 8th directly to the locking pin 15th coupled and are of a direction of movement of the locking device 2 , based on the locked closed position of the sash 4th to the frame 5 in the adjacent position of the wing 4th to the frame 5 to 5 into a rotary position 7th or in a tilted position 8th automatically transferred in a drive-related manner and further from the tilted position by a deflection device in a second direction of movement for actuating the power transmission means 8th to 11 into an open tilted position 12th of the wing 4th to the frame 5 diverted.

To achieve a concealed position in a rebate between the frame 5 and the wing 4th the window or the door 3 arranged opening device 1 to 1 , the driver follows 12th and the hook 13th lying on top of each other, with pulling in of the power transmission means 8th in the housing 22nd the opening device 1 the arcuate section 19th the guideway 20th for the power transmission means 8th . On the last chain link to the free end of the power transmission device 8th , is after 5 to 13th on the driver 12th of the connecting rod connecting element 10 a leader 23 arranged, which the circular arc-shaped section 19th to 10 follows, with the driver 12th along with the hook 13th at an angle of almost 90 ° around the axis 24 of the driver 12th and hook 13th located locking pin 15th twisted. With further retraction of the guide link 23 in the housing 22nd the opening device 1 the driver engages 12th further into the locking pin 15th , bringing the locking device 2 is operated.

To 12th is the power transmission means designed as a chain 8th with the sash tilted open by motor 4th with the driver 12th and the hook 13th of the connecting rod connecting element 10 out of the case 22nd of the base part 6th extended in a free section offset by 90 ° to the direction of movement of the locking device 2 convicted. In the extended tilted position after 12th , is the opening device 1 in an extended end position of the musculoskeletal system of the power transmission means 8th . In the extension movement of the opening device 1 from the tilted position to the open tilted position or vice versa 11 and 12th , is the connecting rod connecting element 10 across the extension direction of the sash 4th or in the direction of the arrow 31 in the one on the wing 4th or the locking device 2 arranged guide element 18th Positioning held aligned. After motorized transfer to the tilt position 9 , the connecting rod connecting element 10 with a parallel course in the guideway 20th linear to the direction of movement of the locking device 2 the window or the door 3 concealed between the housing 22nd and locking device 2 until it is in the locked position 5 move. The stroke of the locking device 2 the window or the door 3 gives the motorized adjustment path of the opening device 1 from the locked closed position to 5 up to the tilt position 9 in front. After the motor-driven tilt position of the opening device 1 and the tilt position of the locking device 2 which is also the end of the stroke of the locking device 2 and thus the locking pin 15th represents, the motorized movement of the opening device follows 1 via the power transmission means 8th the chain in the direction of the open tilt position without further adjustment of the locking pin 15th .

The rigid back chain of the power transmission 8th , is for motorized opening and closing from the tilt position to the opened tilt position of the sash 4th to the frame 5 divided into two sections. The first section is at its first free end 11 of the connecting rod connecting element 10 formed with tensile and compressive forces transferring buckling resistant chain links. The second free end 33 , which in the guideway 20th of the housing 22nd ends and forms the second section, is formed by eliminating intermediate plates to enable back stiffness with standard chain links. The flat arrangement of the chain in the second partial section with formed standard chain links make a contribution to a concealed installation of the chain and thus at least support a concealed arrangement of the opening device 1 in the window or the door 3 at (this 5 ).

The leading member 23 goes, for example after 5 , with the driver 12th a fixed connection, for example a riveted connection. With a non-positive connection of the guide link 23 on the driver 12th and coupled connection at the free end 11 one of the back stiff chain links of the chain 8th , forms the guide link 23 with an arrangement of lubricants, in this embodiment with sliding rollers, a leading bearing in the guideway 20th .
