The device is controlled by an electric drive with a reversing motor and connected transmission means. The drive is housed in a housing on the window or door frame, the transmission element driven by the transmission means being connected to the main frame by means of a clamping clip.

Prior art:

EP-A2-0397179 discloses a cable-operated tilting window in which the closing and release

2q of the bowden elements, as well as the opening and closing of the openable window frame, between the closed position and the folded or vented position can be electrically operated, a bowden drive motor mounted on the window control handle which drives the bowden transmission means on the respective frame by means of a conventional square shaft. . For electric opening and closing of the window with released bowden elements, an electric drive acting on the bowden transmission means connected to the window frame is provided on the upper part of the main frame. The arrangement is microprocessor controlled and in addition has one or more sensors for determining the state of the bowden elements to ensure that the opening / closing function is not performed with the bowden elements in the closed position. The signal connection to the sensors and the current line to two separate motors necessarily leads to a complex electrical line installed in the window frame together with a separate cable loop from the window frame to the electrical installation built into the main frame.

It is an object of the invention to provide an actuator in which one electric drive and transmission means are used to close and release the locking mechanism and to create movement between a closed position and a vented or tilted position.

Summary of the invention:

According to the invention, this is achieved in that the transmission means are additionally designed for functional connection with a locking mechanism mounted on the frame. The transmission means are adapted to engage a first support member operatively connected to the square shaft connected to the locking mechanism, for reciprocating rotation of the square shaft between positions corresponding to the locked and released positions of the locking mechanism. Likewise, the transmission means are adapted to engage a second support member connected to the transmission element to move the transmission means in the opening or closing direction for continued rotation of the square shaft to release or secure the locking mechanism.

The electric drive according to the invention is mounted on a frame into which the locking mechanism engages in place of the control rotary handle with a square shaft.

With regard to the use of the same drive unit and housing for mounting on any vertical frame, a preferred embodiment of the actuator according to the invention is characterized in that its housing has the shape of an elongated box with an opening for a transmission element in one of its side walls and on walls perpendicular to this wall. it is equipped with keyways for sliding in the suspension rail attached to the frame and for sliding in the cover rail.

According to a preferred embodiment of the invention, the transmission element between the electric drive and the clamping clip mounted on the main frame of the door or window can be formed as a cable or other element, one end of which is adapted to be attached to the clamping clip. The electrical line for supplying the motor is guided by a cable conductor with contacts on one side of the pipe electrically connected to the contacts on the clamping clamp. This eliminates the dangerous-looking separate cable or wiring between the main frame and the door or window frame.

According to another preferred embodiment of the invention, the square shaft for actuating the locking mechanism is led out of the housing and connected to an actuating rotary handle, which is usually released from the square shaft, but can be engaged therewith by means of a spring actuating element. By means of the actuating handle, the locking mechanism can be manually operated at any time, for example in the event of a power failure or when it is necessary to open a window or door beyond a ventilated or tilted position usually around a vertical axis, for example to clean a window.

2θ By a special arrangement of the second support member, it can be ensured that the electrical control is switched on automatically when the power supply starts working again or after the manual operation has ended.

The compact arrangement of the electric drive has the consequence that the controller according to the invention can be mounted on most known windows or doors with bowden closure or other type of locking mechanism, and that the controller is also very suitable for remote control and remote indication because directly into the housing without for example, sensors for determining the status of the locking mechanism, a wireless signal receiver, for example, an infrared remote control signal receiver and / or an alarm device.

The invention will now be explained in detail in connection with an embodiment of the invention as a cable-operated pivot / tilt window, with reference to the accompanying drawings.

Examples of embodiments of the invention:

Fig. 1 shows a housing in which an electric drive with a motor and transmission elements is housed, in the shape of an elongated box designed to directly attach the housing to a vertical frame (not shown) of a door or window into which the locking mechanism fits.

For easy mounting and attachment to any vertical frame, it has a housing 1, from which a component is inserted through the side wall 2.

..... . . . .

transmitting an opening / closing movement, which in this embodiment is formed as a hollow tube with a cable, on the top wall, perpendicular to the side wall 2, an upper keyway 3 for sliding on a suspension rail 5 screwed to the respective vertical frame and on the bottom wall, perpendicular to the side wall 2, the lower wedge groove 4 for the insertion of the cover rail 6.

In connection with the suspension on one vertical frame, the lower wedge groove 4 is adapted to slide on the suspension rail 5, while the upper wedge groove 3 is used in connection with the suspension on the other vertical frame. The upper wedge groove 3 and the lower wedge groove 4 can, as shown, have a dovetail cross-section corresponding to the trapezoidal cross-section of the suspension rail 5 and the cover rail 6.

To actuate the locking mechanism, which may typically be a bowden cable control mechanism, a square shaft 7 is provided in the housing 1, which is inserted into the frame by a lower hole 8 formed for this purpose in the suspension rail 5 and on the other hand passes out through the upper hole 9 in upper wedge groove 3. Outside the housing 1, the square shaft 7 is terminated in a connecting part 10 for connection to a control handle 11 intended for manual operation. At the transition between the square shaft 7 and the connecting part 10, a circular groove 12 is formed for inserting a lock 13 formed at one end of the cover rail 6. The square shaft 7 is thus secured in the axial direction.

The connection between the connecting part 10 and the actuating handle 11 is formed so that the actuating handle 11 is usually released from the square shaft 7, but can be operatively connected to the square shaft 7 by a prestressed actuating element 14. To facilitate this activation, the end of the square shaft 7, located outside the housing 7, provided with a visible indication of the position of the locking mechanism, for example, as shown, in the form of a groove 14 'into which the actuating element 14 can fit.

In order to obtain protection against burglary and to ensure the safety of children, the control handle 11 may have a locking device preventing the connection of the control handle 11 and the square shaft 7.

As can be seen from Figures 2 and 3, the electric drive comprises an electric reversing motor 15 whose output shaft drives, via a gear train 16 to 20, a sprocket 21 for an endless chain 22 whose path is defined by a first guide disk 23 on one end and a second guide disk 24 at the other end of the housing 1. Instead of an endless chain 22, a toothed belt and the like, friction-free transmission means can be advantageously used.

To actuate the square shaft 7 connected to the locking mechanism and the bowden cable 25 serving as a transmission element for the opening / closing movements, engaging elements in the form of a first point 26 and a second point 27 are attached to the endless chain 22.

In the embodiment shown, the square shaft 7 is secured by means of square holes (not shown) in the first disk 28 and in the second disk 29, which, by means of connecting struts 30, form a wheel 31 with the same axis as the second guide disk 24.

The first support member, represented by a two-state element 33 with a first arm 34 and a second arm 35, is rotatably mounted between the first disk 28 and the second disk 29 on a pin 32 eccentrically mounted in the first disk 28. As schematically shown in FIG. the element 33 is actuated by a prestressed spring 36.

The electrical control of the square shaft 7 is realized by engagement between a first point 26 attached to an endless chain 22 and a first arm 34 or a second arm 35 of a two-state element 33 and is explained in detail in the following description.

In the embodiment shown in Figs. power supply for electric reversing motor 15.

The cable 25 is, by means of a clamping clip 44, fixed to the main frame 42 opposite to the vertical frame on which the housing 1 is mounted. The electrical connection of the connecting line 40 and the cable installation 43 located in the main frame 42 is formed by two or more contact points 44 in the clamp 41 and corresponding contact points 45 at the end of the hinge 46 of the cable 25 which is removable from the clamp 41. to allow the door or window to be opened in a ventilated or tilted position.

In the housing i, the hollow cable 38 of the cable 25 is connected to a second support member 47 which, as shown in Fig. 4, is formed as a U-shaped element with the open side facing downwards for insertion of a second tip 27 attached to the endless chain 22. the support member 47 has a first impact face 48 for engaging the second tip 27 as it moves in the opening direction, and a second impact face 49 for engaging the second tip 27 as it moves in the closing direction. The second support member 47 is rotatably connected to the hollow cable 38 of the cable 25 by means of a pin 50 and cooperates with a guide rail 51 fixedly attached to the housing 1 and having an inclined guide section 52 through which part of the second support member 47 with the second impact face 49 can be lifted to the second support member 47 is released from the second tip

27.

Since the second support member 47 in the closed door or window position occupies the position 47a indicated by dashed lines in Fig. 4, it is possible in this position to open the door or window to the ventilation or tilted position manually without releasing the cable 25 from the clamp 41. The inclined guide section 52 on the guide rail 51 causes a part of the second support member 47 to be lifted by means of the transverse reinforcement 53.

A portion of the second support member 47 with the second impact face 49 is also formed with an inclined surface 54 that allows the same lifting movement through the second tip 27 when the second tip 27 moves from a position outside the second support member 47 in the direction indicated by arrow 55.

If the window is opened manually, the electric control is automatically reset by activating the electric reversing motor

15.

Manual operation of the door or window is possible in any position by releasing the cable 25 from the clamping clip 41 and using the control handle 11. The operation then takes place in the same way as for a door or window without an electric control.

The controller according to the invention operates as follows. When the electric reversing motor 15 is activated in the closed position of the door or window and with the locking means locked, the first tip 26 is in the position shown in Fig. 2 and the endless chain 22 is driven in the direction of the arrow 56. After a short free movement, the first point 26 engages the first arm 34 on the two-position element 33 in position 26a, thereby moving the two-position element 33 simultaneously with the endless chain 22 and the wheel 31 rotated to rotate the square shaft 7 accordingly. after rotating 180 °, the bowden elements are transported close to the fittings in the main frame so that they cannot be moved further. The supply to the electric reversing motor 15 then increases so that the load on the prestressed spring 36 of the two-state element 33 is exceeded, whereby the two-state element

33 rotates to its second stable position while the first tip 26 is released from engagement with the first arm 34.

After one minute of position 26b, the second tip 27 engages the second support member 47, which in its initial position is in position 47a indicated in dashed lines in FIG. The second tip 27 is thus brought into engagement with the first impact face 48 and drives the cable 25 in the opening direction, which coincides with the arrow 56. In order to stop the cable 25, the housing 1 has an adjustable stop 57 on which the second support member 47 rests when the frame reaches the ventilation or tilting position determined by the adjustable stop 57. Electric power supply

The reversing motor 15 then increases, which is detected by the control circuit, not shown, of the electric reversing motor 15, which switches off the electric reversing motor 15.

During opening, the first tip 26 moves to position 26c ⁰ shown in Fig.2.

When closing the window, the electric reversing motor 15 is started in the opposite direction and the second tip 27 will now move the cable 25 in the direction of the arrow 58 via the second support member 47 until the second support member 47 reaches the position 47a shown in dashed lines in FIG. During the continued movement of the endless chain 22, the second tip 27 is now released from engagement with the second support member 47. At the same time, the first point 26 has moved from its initial position 26c to a position 26b in which it engages the θ second arm 35 of the two-state element 33, causing the wheel 31 and thus the square shaft 7 to rotate in the closing direction until the initial position 26a. In this position, the square shaft 7 is locked and the supply of the electric reversing motor 15 increases until the load of the prestressed spring 36 of the two-state element 33 is exceeded,

I which now flips again to the position shown in FIG.

In the previous description, it is assumed that the frame is transported to the folded position with the square shaft 7 in the position it occupies when the locking mechanism is released, i.e. a rotation of 180 °. With regard to the setting of the control for frames requiring a rotation of the square shaft 7 by 90 ° in order to reach the tilted position, the tilting of the two-position element 33 must already occur in position 26b, which can be achieved by stopping the tip acting on the two-position element 33.

The overall arrangement of the electric drive for the actuator according to the invention makes it possible to add sensors in a simple manner to record the state of the locking mechanism, since such sensors 59 can be mounted in the housing 1 and cooperate with the wheel 31.

The operation of the electric drive can be controlled by control switches located on or in close proximity to the main window frame, but the overall arrangement allows the assembly to be remotely controlled by supplementing the housing 1, as schematically shown in Fig. 2, with an additional module 60 containing a signal receiver 61. for wireless transmission of operating signals controlling an electric reversing motor 15.

The corresponding transmitter of the remote control signals may be equipped with a display for showing the status of the window or door, i.e. the position of the locking mechanism and the degree of opening in the ventilated and tilted position.

In embodiments with on-site control, such a display 63 may rather be located in the second add-on module 62.

These additional electrical devices, like the electric reversing motor 15, can be supplied by a line passing through a hollow cable.

25.

In the arrangement of Figs. 6 to 8, the opening / closing motion transmission element is formed by a fixed arm 64 which is connected by means of a pivotal link 65 to a main frame clip 66 and at the other end has a projecting pivot pin 67 housed in a sleeve 68 mounted in the hole. 69 in a guide rail 70 located inside a groove 71 on the side wall of the actuator housing 72.

The square part 73 after actuation of the locking mechanism, connected to the rotary actuating handle 74, can be formed in accordance with the embodiment of Figs. 1 to 5.

Also in the embodiment of Figs. 6 to 8, the actuation of the locking mechanism and the transmission element formed by the fixed arm 64 is secured by means of an endless chain 75 into which the sprocket 76 fits. 2 and 3 and is connected to a reverse electric motor, not shown.

A hole for the square shaft 73 is formed in the insert 77, which can be connected by a tangible connection to a sprocket 78 engaging the endless chain 75. This sprocket 78 forms in this embodiment a first support member. The releasable link is formed by a pull-out coupling roller 79, which is pressed by a cylindrical spring 80 into a recess 81 parallel to the axis and formed on the outer cylindrical side of the head insert 82, and a lock 83 also parallel to the axis and formed in a cylindrical collar 84 connected to the insert 77. In the active binding position, the lock 83 is firmly secured in the recess 81 by means of a pull-out coupling roller 79. The release of the link is effected by blocking the rotation of the insert 77 and the locking mechanism in each of its extreme positions, locked and released, striking the stop or impact face, the continuing rotation of the gear 78 pushing the pull-out coupling roller 79 out of the recess 81. cylindrical springs 80 so as to allow further rotation of the gear 78 relative to the locked insert 77 with the cylindrical collar 84.

In the embodiment of Figures 6 to 8, the second support member is formed by a latch 85 which is rotatably connected to one end of a guide rail 70 connected to a pivot pin 67 of the fixed arm 64. The latch 85 is similar to the second support member 47 of the embodiment of the Figures 1 to 5 are formed as a U-shaped element with the open end facing downwards for engagement with a support member 85 projecting from the endless chain 75, which, as shown, may consist of a chain link attached to one member of the endless chain 75. The latch 85 thus has a first impact face 87 for engagement with the support member 86 when moving in the opening direction and a second impact face 88 for engagement with the support member 86 when moving in the closing direction. The latch 85 is spring biased against the position indicated by the solid line in Fig. 8, in which the second impact face 88 is moved out of the path of the support member 86.

A pin 89 for pivotally connecting the latch 85 to the guide rail 70 is located vertically above the first impact face 87. The latch 85 cooperates with a rail 90 fixed in the housing 72 in which a recess 91 is formed to receive a cam 92 projecting from the latch 85 at the position indicated on Fig.8 with a solid line. When the support member 86 strikes the first impact face 87 against the biasing spring of the cam 92, the cam 92 can be released from the aforementioned position by releasing it from the recess 91 in the bar 90, thereby trailing the support member 86 to the latch 85 guide rail 70.

The pivot pin 67 of the fixed arm 64 is thus moved to the opposite end of the groove 71 in the side wall of the housing 72, thereby opening the window or door to the vented or folded position.

When the actuator is controlled to operate in the closing direction, the latch 85 and guide rail 70 are towed by a support member 86 resting against the second impact face 88 of the latch 85. When the guide rail 70 has moved so much that the cam 92 of the latch 85 is positioned against the recess 91. in the bar 90, the latch 85 is released from engagement with the support member 86 by a biasing spring. The gear 78 will be further rotated back enough to re-position the recess 81 in the head liner 82 against the lock 83 in the cylindrical collar 84, thereby re-establishing the connection between the gear 78 and the liner 77 via the retractable coupling roller 79 and causing the locking mechanism as the gear 78 continues to rotate, it assumes a locked position.

By moving in the closing direction, the power input of the motor is increased by the action of the cylindrical spring 80 on the gear wheel 78 when this gear wheel 78 is pushed out of engagement with the recess 81 in the head insert 15 by stopping the locking mechanism in the locked position.

82.

Switching off the motor supply when moving in the opening or closing direction can be precisely determined by microprocessor control.

2q Also in the embodiment of FIGS. 6 to 8, the power line for powering the reverse electric motor and the add-on modules may pass through a fixed arm 64.

The embodiment of Figs. 6 to 8 may, similarly to the embodiment of Figs. around 78.

Although the invention has been described with reference to bowden only

3Q operated tilting windows, the actuator can be used in any other type of windows and doors in which the frame in the locked position is secured to the main frame by a locking mechanism activated and released by a rotary movement. The support element for the opening / closing movement can be designed in a different way than described above, so that the actuator can also be used for sliding windows and doors which are opened and closed by means of an electric drive or otherwise.
