Description

TECHNICAL AREA

The invention relates to a facade element and a fitting for opening and closing the facade element by manually turning and motor tilting. The facade element may be a window, a patio or balcony door, a skylight, a flap or the like.

STATE OF THE ART

Facade elements such as those of the present invention have at least one frame and one wing, the latter being able to be opened and closed in a tilting as well as a rotating manner relative to the frame. On the opening and closing enabling devices is usually referred to fitting and on the turning and tilting enabling fittings in particular with Drehkippbeschlag reference.

Tilt & Turn fittings are usually fittings with one-handed operation. They serve to bring windows and balcony doors by pressing a handle in a rotary motion or in a limited tilted position. They are executed on vertically installed façade elements made of any materials and material combinations. Commercially available Tilt & Turn fittings have a gearbox with handle or olive, a corner drive, a scissors-type scissors, a turn-tilt bearing, a tilting holder, a locking pin, a bolt slide, a closing piece and push rods.

A rotation of the handle or the olive is converted in the transmission in a rectilinear movement of the push rods. There are usually three different positions possible: the shutter, the tilt and the rotational position. For the Closing position brings a rotary motion on the handle on the push rods, the locking pins behind the strikers into engagement and the scissors is locked. The wing is then positively connected to the frame or pressed against the seal. The tilting position is achieved in that by a rotational movement on the handle, which in turn is converted in the transmission in a rectilinear movement of the push rods, the locking pin moves away from the strikers and scissors and frame are unlocked. The bolt slide then presses into the tilting holder and the sash can tilt out of vertical until the scissor limits the inclination. For the rotational position, the scissors must be locked, but bolt and bolt slide must be unlocked.

At least tilting can be done not only manually, but also by motor. Fittings with partially motorized fittings and for opening and closing of facade elements of the type described above are known per se.

From the EP 1 323 885 A2 For example, a method for driving windows, doors, and the like with a tilt and turn fitting is known, wherein the fitting may assume a tilt release position in which the wing is tiltable with respect to the frame and a rotational release position in which the wing is rotatable relative to the frame. The wing is tilted by means of a motorized actuator. A first actuator opens and closes the window, while a second actuator unlocks and locks the window, and couples the first actuator as needed to the wing and also decoupled from him. The wing must first be unlocked by the second actuator before it can be opened manually.

In the DE 10 2009 027 313 A1 a drive for a wing of a window is described, wherein the wing by actuation of an actuating handle, such as a Window handle, can be brought into a tilted position or in a pivoting position. On the wing a push rod is arranged, which is displaceable by the actuating handle. To connect the drive depending on the position of the displaced by actuating handle push rod releasably connected to the wing, the drive has a connection console. The window can not be automatically tilted and closed, but must first be unlocked by manual operation of the handle or locked at the end.

An alternative, known under the trade name "TipTronic" solution Schüco International KG (a prospectus was available on the filing date at http://www.schueco.com/web2/asset/de/architekten/produkte/fen sterbeschlaege / aluminum / schueco_tiptronic_beschlag / 19491770 / schueco_tiptronic.pdf) dispenses with the mechanical coupling of handle or olive, scissors and locking bolts and instead relies on distributed and individually controlled electric motors on the individual elements.

In the known devices or methods, however, is disadvantageous that the emergency opening of the facade element, e.g. as an emergency exit in the event of a power failure, it is only possible with difficulty because the window can no longer be unlocked by the motor drive. The manual operation is then cumbersome and time consuming. Even in normal operation, the known solutions have the disadvantage that the advantage of the motorized tilting is reduced by only slowly reachable rotary opening position.

PRESENTATION OF THE INVENTION

An object of the invention was to show a fitting construction, which provides a motorized tilting and tilting as well as a quick manual rotation opening and closing of a facade element such as a window, a door, a Skylights, a flap, etc. allows. Another goal was to implement this hardware construction in a facade element.

These objects are achieved by a facade element according to claim 1 and by a Drehkippbeschlag according to claim 11.

By means of the turn-tilt fitting, the wing can be unlocked and locked on the one hand and rotated and tilted with respect to the frame on the other hand. In the following, the Drehkippbeschlag invention is also simplified referred to as fitting and can be designed differently depending on the construction of the said facade element.

The tilting of the wing takes place about a tilting axis, preferably about a horizontal tilting axis, which is more preferably located on the underside of the frame. The tilting movement is motorized, i. in that a motor is provided as drive for the movement. The turning of the wing takes place about an axis of rotation which is perpendicular to the tilting axis and is preferably a vertical axis of rotation. For example, it may be on the left or right side of the frame. The rotation is done manually. The mentioned axes can also run in other directions and at other positions, depending on the application.

In buildings with large windows, doors, etc., which are also located out of reach of people, the opening and closing of such facade elements is associated with some difficulties. Thus, for a particularly large and thus heavy wings difficult to move manually, especially from a tilted position be closed, and on the other inaccessible windows, doors, etc. not be manipulated without tools. In addition, the ventilation of or the climate in buildings is often controlled automatically. Consequently, a motor and possibly even automatic tilting and tilting of the wing of such facade elements of great advantage and is achieved with the present invention. To further clean these elements or to use as an escape route, the possibility of a quick manual rotary opening is given.

The facade element according to the invention is specified in claim 1. Advantageous developments can be found in the subclaims.

The device according to the invention and the method according to the invention make it possible to open and close the wing relative to the frame both purely automatically in the tilting direction and also purely manually in the direction of rotation and thus enable the desired improved operability.

The motor drives of the invention may include an electronic actuator such as a voice coil motor or an electric motor (slip ring motor, three-phase synchronous machine, cascade machine, stepping motor, brushless DC motor, linear motor, capacitor motor, shaded pole motor, synchronous motor / single phase asynchronous motor, reluctance motor, magnetic motor, transverse flux machine, DC motor, universal motor , permanent magnet DC motor, series motor, bypass machine, compound motor, homopolar engine, Barlow wheel, etc.) or a hydraulic actuator or a pneumatic actuator. For the locking drive and a manual drive, for example via a crank mechanism or a lever mechanism is conceivable.

The term handle used may include a handle, a lever, a knob or knob, a knob or knob Draw wire and the same with which it is possible to move a mechanism like the gearbox. The handle can also be coupled via a connecting element to the transmission and thus be removable, wherein the connection is preferably an olive and particularly preferably can be hidden behind a cover when the handle is removed. The cover can be implemented as an aperture, for example.

A removable handle can be advantageous for the overall visual impression of a facade element according to the invention and for safety reasons. For example, children should be prevented from unattended opening. By removing the handle, this is made possible in the simplest way.

The locking drive can be equipped with a motor provided in addition to the motor of the tilting drive. In such a separate control of the two drives, the necessary connections for the coupling of the respective drive and gearbox can be implemented in a particularly simple and thus cost-effective manner. Electric motors are inexpensive, reliable, easy to attach and precise to control. Hydraulic or actuators in turn are in particularly heavy wings, etc. advantageous because they can muster high forces.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The embodiments described in detail below are mere examples that facilitate the understanding of the present invention and are not intended to be limiting.

Fig. 1 shows the schematic representation of an embodiment of the present invention by schematically illustrating the movements of the Drehtippbeschlags invention.

The turn-tilt fitting according to the present invention comprises at least one frame-fixed closing piece 10 and a locking pin 11 fastened to the wing, which is referred to below as a pin for short. When the pin 11 is in the position behind the striker 10, the striker 10 makes it impossible for the spigot 11 and hence the sash to move away from the frame so that the sash is not moved out of its closed position can. The pin 11 can be moved out of its position behind the striker 10 and into an unlocked position in two opposite directions. In both unlocked positions, movement of the wing relative to the frame from the closed position and into the closed position is possible. One of the two unlocked positions is the tilt-unlocked position, in which opening and closing is possible by tilting, and the other of the two unlocked positions is the rotationally unlocked position, in which opening and closing by rotation is possible. In the embodiment according to Fig. 1 is the locked position between the tilted and drehentriegelten positions.

Further, the Drehkippbeschlag comprises a driver 12. When moving the driver, the driver 12 takes the pin 11 with as soon as the driver reaches the pin with one of its two stops. As shown preferred, both movements, that of the driver and that of the pin, are translatory movements. The driver 12 has a Leerhub, according to the embodiment Fig. 1 is about as large as the stroke that the pin 11 requires to move out of its position behind the striker 10 out. The driver 12 is driven by a motor (not shown).

The pin 11 can also be moved by a gear (not shown), which is operated manually via a handle 16 in the embodiment. The transmission is preferably one without screening, for example an inlet or folding gear. The handle can be designed in different ways, such as a handle, a lever, a knob, a knob, a cable or the like. The handle is coupled via a (not shown) connecting element to the transmission. It may be designed to be removable, wherein the connecting element for the handle on the transmission preferably with an olive for example, a simple Vierkanteinschub. If the handle 16 is removed, the connecting element behind a cover such as a shutter can be hidden.

The opening and closing of the wing relative to the frame in the tilting direction is motorized. For this purpose, a fixed to the frame, shear-resistant chain 13 and located on the wing chain bearing 14 are provided. The chain 13 is secured in the chain bearing 14 by means of a bolt 15, which is displaceable in the exemplary embodiment. The bolt 15 moves in and out of suitable seats in the chain bearing 14 and in the chain 13. When retracted bolt 15 chain and chain bearing and thus frame and wings are locked. The chain 13 then establishes a frictional connection between the window and the frame and thus serves to transmit power between these elements.

To connect the chain 13 and wing can be used instead of a pin 15 any profile element with matching receptacles in the chain bearing 14 and the chain 13. It is advantageous if the recordings and the profile element have play to compensate for any shifts between wing and frame and to allow a safe insertion of the profile element in the recordings.

The bolt 15 is moved by the gear synchronously with the pin 11, whereby the securing of the chain 13 in the chain bearing 14 can be canceled or produced.

A tilting axis, around which a tilt opening and tilting of the wing takes place relative to the frame, preferably runs horizontally. This axis is defined by appropriate Drehkipplager, latch slide and tilt bracket between the frame and the wing. In this case, said bearings are particularly preferably arranged such that said axis extends in a lower portion of the facade element. A The axis of rotation, around which a rotational opening and rotational closing of the wing takes place relative to the frame, preferably proceeds vertically. This axis is determined by appropriate Drehkipplager between the frame and the wing. In this case, said bearings are particularly preferably arranged such that said axis extends in a lateral portion of the facade element.

An opening and closing of the wing relative to the frame in the tilting direction is effected by a rotation of the wing about the tilting axis. The power transmission takes place by means of the shear-resistant chain 13. The chain 13 is secured by the bolt 15 in the chain bearing 14. As a result, a power transmission between the frame and the wing is possible. When the chain 13 is extended, the wing makes a tilting movement in the direction of opening and moves away from the frame. When the chain 13 is retracted, the wing makes an opposite movement in the direction of closing and approaches the frame. In the usual way, the maximum tilt angle depends on the size of the wing and the scissors.

An opening and closing of the wing relative to the frame in the direction of rotation is effected by a rotation of the wing about the axis of rotation. To open in the direction of rotation, a force which acts at a point remote from the vertical axis is exerted on the wing in the direction of opening. To close a force is applied in the opposite direction in the same point of attack. The introduction of force at said point can preferably be done via the handle. The angle in which the wing can be issued in the direction of rotation is above 0 ° and up to 180 °, preferably from 0 ° to 120 ° and particularly preferably from 0 ° to 90 °. Smaller Ausstellwinkelbereiche are also quite possible.

The pin 11 is, as already described, on the one hand by the motorized driver 12 and the other on the Handle displaceable by means of the transmission. Therefore, the pin behind the striker 10 can be moved out in two ways, so that a relative movement of the wing to the frame is possible.

Hereinafter, the operation of the turn-tilt fitting and the movement conditions will be described with reference to FIG Fig. 1 described in more detail.

In Fig. 1 in the left column, the position of the handle 16, in the middle column are chain bearing 14, chain 13 and bolt 15, and in the right column, the positions of pin 11 and driver 12 are shown relative to the closing piece 10. The closing piece 10 is given only once again. After it is stationary, the edges of the striker for each of the positions shown are represented by the vertical lines.

V11 schematically represents a starting position of the lock. The sash is completely closed. The pin 11 is located behind the closing piece 10. The facade element is locked and can not be opened. The driver 12 is located with his right stop on the pin. If the facade element to be opened by motor in tilt direction, the pin 11 must be brought into a Kippentriegelungsstellung. For this purpose, the driver 12 is displaced away from the locking piece 10 by the locking drive. The driver first passes through a hub in which the pin is not moved. On this hub is referred to idle stroke. During the idle stroke, the handle 16 and the bolt 15 do not move. Only when the idle stroke is overcome and the left stop abuts the pin, the pin 11 is moved by the driver 12. This is exactly the case with V12. If the driver continues to move, the pin 11 is moved by the driver 12 to the Kippentriegelungsstellung V13. Also, the handle 16 and the bolt 15 move with. Upon reaching the Kippentriegelungsstellung the wing can be opened by the tilting drive in the tilting direction, which is indicated schematically by the double arrow.

If the façade element is to be closed again from a tilt-open position, first the wing is pulled back into the frame by the tilting drive. Thereafter, the driver 12 is moved back to the striker 10 to. The pin 11, the handle 16 and the bolt 15 in turn are not moved until the idle stroke is overcome. This is the case with V14. Upon further movement of the driver, the pin 11 is taken and moved behind the striker 10. The facade element is in a locking position V15, which corresponds to the starting position V11. The facade element is locked and the wing can not move relative to the frame.

If now the facade element to be opened in the direction of rotation, u.a. to be separated via the frame-fixed chain 13 and the wing-fixed chain bearing 14 traction. For this purpose, the pin 11 and the bolt 15 are moved by rapid rotation of the handle 16. The pin 11 is moved from the locking position V15 behind the striker 10 out in another than in the direction of Kippentriegelungsstellung, preferably exactly in the opposite direction. This movement takes place via a stroke which is approximately equal to the idle stroke of the driver 12, without this having to be moved. In this rotational unlocking position V16, the pin 11 is out of position behind the striker, and the bolt 15 has been moved out of the chain 13 and the chain bearing 14 so that the blade can be rotationally opened relative to the frame, indicated by the double arrow ,

If the facade element from a rotationally open position to be closed again, the wing is first rotated back into the frame. Following the pin 11 again within the idle stroke of the driver 12, without this being moved, back into the locking position V17, which corresponds to the starting position V11, moved behind the closing piece 10.

The bolt 15 is, as already described, moved synchronously with the pin 11 through the transmission. In the locking position V11, the bolt 15 is inserted into the chain bearing 14 and the chain 13. In this case, a first end of the bolt 15 is just far enough inserted into the chain 13 and the chain bearing 14 so that they are secured. If the pin 11 is moved via the driver 12 by means of the locking drive in the Kippentriegelungsstellung V13, the bolt 15 also moves into the chain bearing 14 and the chain 13. In this case, the first end of the bolt 15 is further away from the chain bearing 14 and the chain 13 moves and the connection between the chain 13 and the chain bearing 14 is not solved, so that further a power transmission is possible and the wing can be tilted or closed by means of the tilting drive. If the pin 11 is moved back into the locking position V15, the bolt 15 also returns to its initial position as in V11. By displacing the pin 11 via the gear in the rotary unlocking position V16 of the bolt 15 is moved out of the chain 13 and the chain bearing 14 in the opposite direction. The chain 13 is decoupled and the wing can be turned on without the chain 13 obstructing movement between the sash and the frame. If the wing is closed again and the pin 11 is moved back into the locking position V17 via the gear, the bolt 15 also returns to its initial position and the chain 13 is again coupled to the chain bearing 14.

If the handle is connected to the gearbox in the form of a handle, this shows in the initial position or locking position V11, V15, V17 and during the Facade element is locked, at V12, in a horizontal direction. In the tilt release position V13 and while the facade element is tilt-unlocked, at V14, the handle points vertically upwards. In the rotary unlocking position V16 it points downwards in the vertical direction. This is due to the coupling between pins 11, bolts 15, gear and handle 16. It is intended to couple the handle 16 only when needed via the connecting element with the transmission, eg for manual rotation opening for the purpose of shock ventilation or cleaning. If the handle is to be permanently connected and, in certain installation positions of windows or balcony doors, collisions with the soffit are to be feared, a knob can be used instead of a cantilever handle. The listed positions of the handle are anyway only an example, which should illustrate the operation of the tilt and turn fitting. Other angles and positions, especially if the handle is not designed as a handle, will be obvious to those skilled in the art.

The entire process for opening and closing the facade element in the tilting direction can preferably take place completely automatically. For this purpose, first the facade element of the locking drive motor, automatically, possibly sensor-controlled, tilted over a building automation by means of the driver 12 from the locking position V11. Thereafter, the wing is tilted motor by the tilting drive. The closing can also be done completely automatically by first pulling the wing back into the frame by means of the tilting drive. Thereafter, the pin 11 is automatically brought by the locking drive means of the driver 12 from the Kippentriegelungsstellung V13 back into the locking position V15.

For the purpose of emergency opening or other purposes, the tilting drive and the locking drive can also be operated manually. For this purpose, mechanisms such as a crank mechanism and / or a lever mechanism can be used. For the preferred motor and possibly fully automatic tilting movement of the facade element, the two each have a motor. This may be an electromechanical actuator, such as an electromechanical actuator. a voice coil motor, an electric motor, etc., or a pneumatic actuator or a hydraulic actuator. Preferably, however, an electric motor is used as the tilting and locking drive. Furthermore, it is also possible to connect both drives via a suitable gear, e.g. To drive with segment gears or similar, by only one drive described above type.

The automatic Kippöffnungs- or Kippschließvorvorgang can be controlled via a control element such as a button, a toggle switch or the like. This operating element can be connected to a controller which can be realized by a computer, a microcontroller or the like. The controller controls the tilting drive and / or the locking drive.

The entire process for opening and closing the facade element in the direction of rotation is preferably carried out completely manually. For this purpose, the facade element is rotatably unlocked via the handle by the pin 11 is brought from the locking position V15 in the rotary unlocking position V16. In this case, the bolt 15 is moved synchronously out of the chain bearing 14 and the chain 13, so that the chain 13 is decoupled. Thereafter, the wing can be opened manually, preferably via the handle, in the direction of rotation. For closing from the rotationally open position, the wing is moved manually, preferably via the handle, back into the frame. Thereafter, the pin 11 is moved via the handle from the rotationally unlocked position back into the locking position V17 behind the closing piece 10 and at the same time Chain 13 is coupled to the chain bearing 14 by the bolt 15. These movements are familiar to the user and can be done quickly. This has advantages over some fully automatic solutions of the prior art.

Fig. 2 shows the schematic representation of a second embodiment of the present invention. The mechanism essentially comprises the same elements as the embodiment of FIG Fig. 1 , Therefore, only the differences from the previous embodiment will be described.

The pin 11 is unlocked from the striker 10 in one direction only. For this purpose, a driver 12 is used with a Leerhub, which has about twice the value of the stroke, which is necessary for the removal of the pin from its position behind the closing piece.

In the following, the operation of the locking with the driver 12 with double idle stroke will be described in more detail.

V21 represents the initial position of the lock again. The sash is completely closed. The pin 11 is located behind the closing piece 10. The facade element is locked and can not be opened. If the facade element to be opened by the tilting drive in the tilting direction, the pin 11 must first be brought into the Kippentriegelungsstellung. For this purpose, the driver 12 is moved away from the locking drive in a direction away from the closing piece 10. For the driver 12 no idle stroke must be overcome because the driver 12 in the initial position V21 already rests with its left stop on the pin 11. The pin 11 is thus displaced equal to the driver 12 to the Kippentriegelungsstellung V22. In this case, the handle 16 rotates and moves the bolt 15 with. The latter remains locked. Now the wing can be issued by the tilting drive in the tilting direction. If the facade element from a tilt closed position, the wing is first retracted by the tilting drive in the frame. Thereafter, the driver 12 moves back to the striker 10 to. The pin 11 is not moved until the double idle stroke is overcome. This is the case with V23. Then the pin 11 is displaced from the driver 12 to behind the striker 10, which is the case at V24. Subsequently, the driver 12 has to be moved away again by the double idle stroke of the closing piece, in order to reach a locking position V25, which corresponds to the starting position V21. The facade element is locked and the wing can not move relative to the frame.

If now the facade element to be opened in the direction of rotation, the pin 11 is moved from the locking position V25 behind the striker 10 out in the same direction as for Kippentriegeln. This displacement movement takes place within the double idle stroke of the driver 12, without this having to be moved. In the rotational unlocking position V26, the pin 11 is moved out behind the striker and the blade can be rotationally opened relative to the frame. If the facade element from a rotationally open position to be closed again, the wing is first rotated back into the frame. Subsequently, the pin 11 is moved back within the double idle stroke of the driver 12, without this being moved back into the locking position V27, which corresponds to the starting position V21, behind the closing piece 10.

If the handle 16 is connected in the form of a handle to the transmission this shows in the starting position or locking position V21, V24, V25, V27 of the facade element down. In the tilt unlock position V22 and V23, the handle 16 faces in a horizontal direction. In the Rotary unlocking position V26 shows it in a vertical upward direction.

Fig. 3 shows the schematic representation of a third embodiment of the present invention. The mechanism essentially comprises the same elements as the embodiments of the Fig. 1 and Fig. 2 , Therefore, only the differences from these embodiments will be described.

A difference to the embodiment of the Fig. 1 exists in the gear ratio of the transmission. In the embodiment according to Fig. 3 puts the handle 16 in the same way of pin 11 and bolt 15 the double way back as the handle of the embodiment according to Fig. 1 , Another difference is the lack of interlocking frame and sash. While in the embodiment according to Fig. 1 Frame and wings are locked by both pin 11 and striker 10 and by the engagement of bolt 15 and chain 13 and chain bearing 14 is in the embodiment after Fig. 3 waived the lock on the bolt.

The pin 11 is unlocked from the striker 10 in one direction only. For this purpose, a driver 12 is used with a single idle stroke.

In the following, the operation of the locking with the driver 12 is described with a single idle stroke in more detail.

In Fig. 3 V31 represents the initial position of the lock again. The sash is completely closed. The pin 11 is located behind the closing piece 10. The facade element is locked and can not be opened. If the facade element to be opened by the tilting drive in the tilting direction, the pin 11 must first be brought into the Kippentriegelungsstellung. For this purpose, the driver 12 is moved away from the locking drive in a direction away from the closing piece 10. For the driver 12 no idle stroke must be overcome, since the driver 12 is already in the starting position V31 with its left stop against the pin 11. The pin 11 is thus displaced equal to the driver 12 to the Kippentriegelungsstellung V32. Now the wing can be issued by the tilting drive in the tilting direction. If the façade element is to be closed again from a tilt-open position, first the wing is pulled back into the frame by the tilting drive. Thereafter, the driver 12 moves back to the striker 10 to. The pin 11 is not moved until the idle stroke is overcome. This is the case with V33. Then the pin 11 is displaced from the driver 12 to behind the striker 10, which is the case at V34. Subsequently, the driver 12 must again be moved by the idle stroke of the closing piece in order to reach a locking position V35, which corresponds to the starting position V31. The facade element is locked and the wing can not move relative to the frame.

If now the facade element to be opened in the direction of rotation, the pin 11 is moved from the locking position V35 behind the striker 10 out in the same direction as for the tilting. This displacement movement takes place within the idle stroke of the driver 12, without this having to be moved. In the rotary unlocking position V36, the pin 11 is moved out behind the striker and the blade can be rotationally opened relative to the frame. If the facade element from a rotationally open position to be closed again, the wing is first rotated back into the frame. Subsequently, the pin 11 is moved back within the idle stroke of the driver 12, without this being moved back into the locking position V37, which corresponds to the starting position V31, behind the closing piece 10.

If the handle 16 is connected to the gear this shows in the starting position or locking position V31, V34, V35, V37 of the facade element in a vertical direction downwards. In the tilt unlock position V32 and V33, it points upward in a vertical direction. In the rotary unlocking position V36, the handle 16 points in the horizontal direction.

Figure 4 shows the incorporation of the embodiment of the present invention Fig. 1 in a exemplified as a window facade element. However, all subsequent descriptions and explanations may be applied to other embodiments of the present invention, for example, as a door, skylight, hatch, and the like.

In Fig. 4 21 denotes the sash shown in the rotary opening position and 22 the sash. At 13 it is shown how a chain exits from the here frame side mounted in the fold of the upper frame member tilting drive. At 12, the driver is visible. He is here exemplified U-shaped. The legs of the U are the stops for the pin 11 ( Fig. 5 ). Between the legs of the U results in a void that allows the driver to proceed over the Leerhub described above. The amount of Leerhubs corresponds to the distance of the legs in the direction parallel to the lower frame spar. Further, 10 in Fig. 4 a here executed on both sides closing piece. On the opposite sides, in the right and left in Fig., The striker is beveled to the pin 11 ( Fig. 5 ) to be frictionally retracted from both sides, namely by applying pressure to the gaskets, and to lock the sash of the window to the frame.

There are several pins 11 provided around the circumference of the sash. Two of them are in Fig. 5 shown. The in Fig. 5 the reference numeral 11-1 bearing pin acts with the closing piece 10 ( Fig. 4 ) and the pin 11-1 supporting pin acts with the driver 12 ( Fig. 4 ) together.

Fig. 6 shows the attached in the upper spar of the casement chain bearing 14 and designed as a bolt 15 positive locking element. The chain bearing has in this example two openings for the positive locking element, one left and one right in the figure. In the left opening, the positive-locking element is added, from the right opening, the positive-locking element is removed. The positive locking element 15 is thus shown in the position in which the chain and the chain bearing are separated from each other. When the sash is closed, the end of the chain moves to hiss the openings of the chain bearing. Then, when the bolt 15 carried by the push rods conventionally provided in the figure is moved to the right through the opening in the chain and through the right opening in the chain bearing, the frictional connection between the wing and the frame is established via the chain 13.

Fig. 7 shows a plan view of the scissors 30. The closing piece 31 of the scissors is clearly visible. On one side it has a lock 32. On the other hand, at 33, the latch has been removed to allow the latching position, in which the vanes and frame are locked, to be between the tilt unlock position and the pivot unlock position. For the embodiments according to the Fig. 2 and 3 appropriate adjustments have to be made, as the person skilled in the art will recognize.
