Description

The invention relates to a fitting for a rotatable and tiltable window and / or door, consisting of a housing, a rotatably mounted on the housing pusher and a control mechanism which is adjustable via the pusher between at least three positions of the window and / or door leaf wherein the window and / or door is held closed in a frame in a first position, tilted in a second position about a horizontal axis relative to the frame, and pivoted in a third position about a vertical axis relative to the frame.

Such fittings are known in various embodiments from the prior art.

As is known, doors and windows typically include a pusher for actuating the door and / or the window. These pushers can often, depending on the design, have different 90 degrees offset basic positions. For example, in the vertical down position, the pusher may mean that the door or window is closed, the pusher in the horizontal position means that the door or window is open, and the pusher in the vertical up position the door or window is in the so-called tilt position. Of course, it must of course be stated here that the window has a frame and a window sash or the door has a frame and a door leaf, with sashes and door leaves being adjustable relative to the frame, so that a fully open position of the window and / or door leaf or door leaf is adjustable tilted position can be taken.

Often there is a need to lock the pusher in one of these positions so that it can not be moved. For example, you want to prevent a closed door that it can be opened by the operation of the pusher. For this purpose, solutions are known in which the pusher has a lock with a lock cylinder, wherein the lock locks the rotation of the pusher relative to the window and / or door. The lock is opened or locked via the lock cylinder and a key inserted therein with a corresponding locking secret. With such a closing device is possible to lock the window and / or door in the closed position, so that a non-destructive opening of the window and / or door is not possible. However, these prior art fittings have the disadvantage that you have to be very voluminous to accommodate lock and lock cylinder and on the other hand only allow the possibility of locking.

An improved fitting with a fitting protection, for example, from the EP 3 258 036 A1 known. This fitting has proven successful but only solves the problem that the fitting compared to prior art fittings can be made less bulky. For this purpose, a fitting body and a pusher is provided in this fitting with a fitting securing, wherein the pusher is rotatable relative to the fitting body and wherein the rotation of the pusher is transferable to a polygonal mandrel, wherein the pusher has a coupling mechanism, which coupling mechanism is a clip assembly and a Shock element comprises and wherein the clamp assembly and the impact element lie on a common axis.

It is an object of this invention to develop a generic fitting such that a locking of the fitting is not only possible with the window and / or door closed, but also with tilted window and / or door, so that the burglary attempts made possible thereby are prevented can, in which the pusher is moved in the tilted state of the window and / or door leaf.

Also this malfunction of the opening or closing of the window and / or door can be prevented from the tilted to the closed position or from the tilted to the open position.

The solution to this problem provides that between the control mechanism and the pusher, a locking device is arranged, with which the pusher in its rotation relative to the housing is lockable such that the window and / or door movable only from the first to the second position is.

After the inventive design of the fitting is thus provided that the pusher can be prevented in a tilted position located in the window and / or door by the locking device to a further rotation, by which the pusher could be transferred to a position in which the window and / or door can be fully opened. This serves on the one hand the burglary protection and on the other avoids the invention thereby incorrect operations in which the window and / or door is no longer statically determined in the frame and not intended by movements damage to the control mechanism in particular the connection between the frame and window and / or door leaves can be caused.

According to a further feature of the invention, it is provided that the locking device comprises a slide and a linear drive, with which the slide between a rotational movement of a locking disc at least limiting position and a rotational movement of the locking disc releasing position is movable, wherein the locking disc rotationally fixed with the pusher connected is.

In this embodiment, it has proved to be advantageous, that the basic mechanics of a pusher in connection with a generic fitting can be essentially maintained. This is the pusher, which is positively connected, for example via a square with the control mechanism, so that, for example, rotational movements of the pusher in linear movements of the control mechanism for opening, closing or tilting of the window and / or door can be implemented. The pusher is in this case rotatably connected to a locking disc, for example, by the square engages through a corresponding opening of the locking disc. The locking disc in turn cooperates with a slide which is displaceable by means of a linear drive between a first and a second position, wherein the slider is displaceable by means of the linear drive in such a second position in which the slider limits the rotational movement of the locking disc. Such a restriction allows rotation of the pusher only between the first position and the second position, so that the window and / or door can only be transferred from the closed position to the tilted position, but not in the open position.

If the window and / or door is to be transferred from the closed to the open position, it is necessary that the slider is transferred from its first position to its second position, so that the locking disc is prevented from rotating by the slider.

It is provided according to a further feature of the invention that between the pusher and the locking device a predetermined breaking point is provided which breaks when a predetermined torque about a longitudinal axis of the pusher and / or exceeding a tensile force in the direction of the longitudinal axis of the pusher and the pusher separates from the control mechanism. Such a predetermined breaking point can be provided for example in the region of the square. This engages with one end in the control mechanism and with its second opposite end in a corresponding opening in the pusher and is fixed there, for example by means of a grub screw.

If the rotational movement of the locking disc is limited by the slide displaced into the blocking position, so that only a movement of the pusher between the closed and the tilted position of the window and / or door is possible, then an excess of a certain torque, which of the pusher on The square is transferred so that the square breaks in the region of its predetermined breaking point and the pusher is separated from the square.

This prevents that located in tilt position window and / or door in the course of a break-in attempt by rotation of the pusher in the full open position can be transferred to allow access of unauthorized persons. If this is done in the fitting according to the invention, then a rotation of the pusher and thus of the square is only possible to a limited extent, which does not allow the opening of the window and / or door. Now, if a larger force is transmitted to the pusher, it breaks off and further manipulation of the pusher are no longer possible. In the same way, it is provided that a tensile force in the longitudinal axis direction of the square leads to a fracture of the square, so that even in this way a further break-in attempt fails.

The pusher is preferably L-shaped and has two legs, wherein a leg passes through an opening in the housing and has a square, which is positively connected to the control mechanism. In general, the square is arranged predominantly in the housing and the protruding from the housing portion of the square is received in a leg of the pusher and connected thereto. The predetermined breaking point of the square is therefore not visible from the outside, so that it could be manipulated, for example, amplifying.

Furthermore, it is provided in a fitting according to the invention that the linear drive is designed as a pressure cylinder and extending radially to the pusher is arranged in the housing. The pressure cylinder may, for example, have a finger approach, over which the pressure cylinder is slidable in the direction of the pusher until it locks with simultaneous displacement of the slider element in the housing. About an unlocking device and this may, for example, be a lock cylinder with a matching key, the pressure cylinder can be unlocked and transferred to the starting position. Supported this movement can be, for example, according to a further feature of the invention by a pressure spring arranged in the slide, wherein the slide is transferred against this compression spring in the locked position and locks the locking disc.

Preferably, the locking device on a handle, in particular by the square accessed by grid plate, which preferably has four equally spaced angularly spaced grooves in the corresponding projections of a spring element can be latched, wherein the spring element braces the grid plate in the axial direction of the pusher in the locking device.

About the grid plate, the end positions of the pusher for the different positions can be specified so that they are, for example, tactile perceptible. Connected thereto may also be an acoustically perceptible signal, so that, for example, impaired people in their visual performance can detect the transfer of the pusher in one of the desired positions. For this purpose, the grid plate has four grooves, two of which are arranged diametrically opposite each other on the screen disc designed as an annular disc. In these four grooves engage four projections of the spring element, which presses the components of the locking device in the axial direction of the square in the required position. In the axial direction, the position of the components of the locking device is locked, for example by an inserted into a hole in the square pin, this hole is aligned at right angles to the longitudinal axis direction of the square.

It is provided according to a further feature that the slide is substantially T-shaped and has two stop surfaces and that the locking disc in cross-section is preferably mushroom-shaped and has at least one projection which can be brought into contact with a stop surface in the second position to prevent further rotation of the pusher and thus a further actuation of the control mechanism. This embodiment of slider and locking disc, the possibility of limited rotation of the pusher is given in the locked position.

Several, at least two fittings can be summarized according to a further feature of the invention to a locking system, the fittings are actuated with keys that have an at least partially matching privacy secret. In this case, a partially coinciding closing secret also means that, for example, in the case of a multiplicity of fittings, a part of the fittings can be actuated with a single key, while a further part of the fittings can be actuated with another key. Overall, however, all fittings of a locking system can be operated with a master key. Thus, access authorizations for different fittings can be assigned.

Notwithstanding the described mechanical closing method with lock cylinder and key, of course, electronic solutions can be provided, for example by the integration of electronically controllable lock cylinders in the fittings. In this case, for example, Bluetooth-based communications may be provided so that either the blocking devices correspond to one another or to a mobile telephone, for example, to receive opening or closing commands. Other electronic devices, such as transponders are of course also possible.

The 1 to 3 show a window 1 consisting of a window frame 2 and a casement 3 , The sash 3 is relative to the window frame 2 movable around a vertical axis 4 pivotable and about a horizontal axis 5 tiltable. 1 shows the window sash in a first position, in which the window 1 is closed while 2 the sash 3 relative to the window frame 2 in a second, around the horizontal axis 5 tilted position and the 3 the position of the sash 3 relative to the window frame 2 shows position pivoted about the vertical axis.

For controlling the opening process of the window 1 from the first to the second or the third position according to 1 to 3 is a fitting 6 provided from a pusher 7 and a control mechanism not shown in detail.

The fitting 6 is detailed in the 4 to 10 shown, to which reference is made below.

Recognizable in the 4 to 10 the fitting has a housing 8th and the pusher 7 on, the pusher 7 is formed as an L-shaped handle and thus has two legs 9, 10. The thigh 9 is at his the housing 8th facing end formed with a square in cross-section opening, the recording of a square 11 that serves in the thigh 9 through a grub screw 12 is fixed.

The square 11 and a stepped portion of the thigh 9 are in an opening of the housing 8th used intervening, with the square 11 the housing 8th fully enforced.

The housing 8th may be formed in two parts and a first screwed to the window frame 2 part 13 that of a cover 14 is completely covered, with the cover 14 with a circumferential face flat on the window sash 3 gets up. The connection between the part 13 and the cover member 14 can be done by friction. But it can also be provided by screwing behind and / or a connection by engaging projections.

On the square 11 attached is a locking disc 15 , a grid plate in front of it 16 as well as the locking disc 15 and the grid disc 16 in constant contact spring 17 , whose pressing spring force in the axial direction of the square 11 is aligned.

locking disc 15 and grid disc 16 have one with the outside dimensions of the square 11 corresponding opening on, so with rotation of the square 11 also the locking disc 15 and the grid disc 16 relative to the part 13 of the housing 8th to be moved.

In the part 13 of the housing 8th used is a linear drive 18 , which is designed as a pressure cylinder and an outer cylinder 19 and an inner cylinder guided therein 20 having. Front side, the outer cylinder 19 an opening 21 on, on both sides diametrically opposite screws 22 are provided, with which the linear drive 18 in the part 13 of the housing 8th is fixed.

By means of the linear drive 21 can one below the locking disc 15 arranged slider 23 be moved between two positions back and forth. The slider 23 is formed in a longitudinal section T-shaped and has two stop surfaces 24 on.

Corresponding to the stop surfaces 24 has the locking disc 15 , which is mushroom-shaped in cross section, two projections 25 on, in a first, namely a locked position with the stop surfaces 24 after a predetermined rotation of the locking disc 15 can be brought into contact and further rotation of the locking disc 15 prevent.

The locking disc is fixed 15 , the grid disc 16 and the spring 17 on the square by a transverse to the longitudinal axis of the square 11 inserted into a hole of the square 11 pin 26 ,

Furthermore, the square has 11 in the area of the transition from the thigh 9 of the pusher 7 a breaking point 27 whose function will be described below. The breaking point 27 may be formed for example by a notch or other material weakening.

10 also shows a fastener 28 which the attachment of the housing 8th and thus the fitting 6 on the window frame 2 serves.

The slider 23 has a compression spring 29 on, which is biased upon insertion of the slider 23 in the locked position, which will be described below, so that the then stored spring energy for the return of the slider 23 can be used in the unlocked position.

In the fitting according to the invention 6 can the inner cylinder 20 be inserted into the outer cylinder 19, thereby thereby by means of the linear drive 18 the slider 23 with its end face in contact with an outer surface of the locking disc 15 is brought. In this contact the slider allows 23 a limited rotational movement of the locking disc 15 relative to the housing 8th until a lead 25 for contact with a stop surface 24 arrives. In this position of the slider 23 can thus the pusher 7 for example, via the grid disc 16 be twisted in two opposite directions by 90 degrees. Another twist of the pusher 7 gets through the stop surfaces 24 in the area of slide 23 and the projections 25 in the area of the locking disc 15 prevented. Thus, the window frame can be 2 from the position in 1 in the position in 2 tilt. Another opening of the window sash 2 , for example, in the position in 3 can not.

Will still the pusher 7 further rotated with great force creates a torque in the region of the predetermined breaking point 27 which leads to the break of the square 11 leads. The pusher 7 becomes hereby of the square 11 separated, so that further burglary attempts are made considerably more difficult.

In the same way, the square reacts 11 in the area of its breaking point 27 in the event that the pusher 7 in the longitudinal axis direction of the square 11 is acted upon by a high force. Thus, by no additional movement of the pusher 7 the window sash 3 with locked locking device 30 be enforced. The locking device 30 consists of the slide 23 and the linear drive 18 ,

The linear drive 18 but can be unlocked by a key with a locking secret, so that the inner cylinder 20 again partially pushed out of the outer cylinder 19. This is done for example by a biased during the locking spring, which relaxes when unlocking and the inner cylinder 20 relative to the outer cylinder 19 shifts. At the same time, the slider 23 in one of the locking disc 15 transferred to the remote position, so that the locking disc 23 now over the pusher 7 rotatable by 180 degrees, so that thereby the sash 3 relative to the window frame 2 is pivotable. The window 1 can thus be opened. For the return of the slider 23 in this position relative to the locking disc 15 is the compression spring 29 in a recess of the slider 23 intended.
