Description

The present invention relates to a window, a door or the like having a fixed frame, a wing and a fitting arrangement.
The fixed frame and the sash of windows, doors or the like often consist of profile parts, which are provided with cavities for weight reduction and are often made of plastic. In a part of the cavities and metal reinforcements or the like are often introduced. The actuation system of the windows and doors usually comprises a drive rod gear, on which cooperating with frame-side closing parts locking pins are provided and which is drivable by means of a handle via a pinion and adjustable between different operating positions. For the corner areas so-called angle drives are usually required, which are coupled to the drive rods. As a result of the drive rods and in particular the angle drives inevitably occur friction. In addition, there is a need for a more comfortable window or door operation, which optionally also allows remote-controlled operation.

In the WO 00/36257 A1 EP-A-0 416 511 discloses a device for actuating a closure, in particular a window or a door, which is provided with a hydraulic or pneumatic drive for opening and / or closing the closure. The hydraulic and / or pneumatic drive comprises a linear actuator, the a piston rod and a piston. In this case, the actuator can be arranged in a cross-sectionally C-shaped or in cross-section annular cavity of a fixed frame. The linear actuator can be acted upon by actuating fluid from a pressure source. In this case, a linear actuator receiving portion of the cavity is closed to the outside and sealed from the adjacent, partially open to the outside regions of the cavity by seals.

In the WO 01/81693 A2 a system for locking window and door wings is described, which includes for locking a respective wing again a hydraulic or pneumatic actuator. Among other things, a pneumatic actuator with a cylindrical piston and a pneumatic cylinder is disclosed, which is arranged in a sash. The cylindrical piston protruding into the pneumatic cylinder with one end is provided at the opposite end with a head which cooperates with a groove provided in the fixed frame for locking the wing. A respective pneumatic or hydraulic actuator is connected via at least one line to a pressure source.

In the DE 10 2009 027 760 A1 a strut fitting for a frame pivotable wing of a window is described which comprises a drive means with a arranged in the folded air between the frame and the wing pressure fluid actuated assembly for locking the wing. The assembly is provided with an acted upon by the pressurized fluid driver. The ends of the driver are each made in one piece with pistons, which are guided in each case displaceably in a base plate and each seal a pressure chamber, which are connected via connections and pressure medium lines with a pressure medium source.

The invention is therefore an object of the invention to provide a window, a door or the like of the type mentioned, which is easier to operate with the simplest possible structure and reliable operation while avoiding interfering friction and optionally also allows a remote controlled operation.

According to the invention this object is achieved by a window, a door or the like having the features of claim 1. The window or door comprises a fixed frame, a wing and a fitting arrangement, wherein the fixed frame is profiled and / or the wing has a profiled wing frame. The fitting arrangement can be switched between different operating states and comprises a hydraulic actuating device, by means of which it can be acted upon correspondingly to switch over between different operating states via actuating fluid. In this case, the actuating fluid is guided in at least one channel formed by a cavity of the profiled sash and / or in at least one channel formed by a cavity of the profiled, fixed frame. The actuating fluid is guided in at least one, preferably not more than one circumferential, closed channel formed by a cavity of the profiled wing frame or the profiled fixed frame. Depending on the configuration, the actuating fluid can thus be hydraulic fluid or a gaseous fluid, for example air, in particular compressed air.

According to the invention, the fitting arrangement comprises at least one locking element associated with the wing and / or at least one locking element associated with the fixed frame, each with an opposite, the fixed frame or the wing associated Closing member cooperates, wherein each of the locking element adjustable and for adjusting by means of the hydraulic and / or pneumatic actuator via the actuating fluid can be acted upon accordingly. The locking element comprises a usable in a groove of the profiled sash or profiled fixed frame base and a relative thereto slidably mounted locking pin, which is acted upon by at least one pressure chamber of the base with actuating fluid, which profiled with a through a cavity of the profiled wing frame or formed stationary frame, actuating fluid-carrying channel is in fluid communication. A respective pressure chamber of the base of the locking element is connected via a self-sealing hollow screw serving to fix the base in the groove of the profiled wing frame or profiled fixed frame to the actuating fluid channel formed by a cavity of the profiled wing or frame.

In this case, the locking elements are preferably associated with the wing and the closing parts of the fixed frame. Are in the profiled wing frame or in the profiled fixed frame each two adjacent channels provided in which actuating fluid is guided in opposite directions of flow, the locking element can be acted upon by two on opposite sides provided pressure chambers of the base with actuating fluid by a pressure chamber with one and the other pressure chamber is in fluid communication with the other channel. The corresponding compounds can, as described in more detail below, in particular be produced via a respective hollow, self-sealing screw via which the locking element can be fixed in the groove. It is a problem-free fixation of a respective locking element at different locations in the groove possible, with the fixation at the same time the required Connection with the at least one actuating fluid channel is made. The at least one actuating fluid-carrying channel may be provided in particular in the region of the respective groove bottom. A respective pressure chamber of the locking element can then be brought into fluid communication in particular with a respective channel in that a respective self-sealing, hollow screw is screwed through the base of the relevant locking element in the bottom of the relevant groove.

According to the invention, the cavities already present in the profiled fixed frame or the profiled wing frame are thus advantageously used to guide the actuating fluid required for hydraulic and / or pneumatic actuation. The profiled wing frame or profiled fixed frame can in particular consist of plastic extruded profiles. With the hydraulic and / or pneumatic actuator a more comfortable operation of the windows or doors without the previously annoying friction is possible, the hydraulic and / or pneumatic actuator optionally also easily allows remote operation. After the required for the hydraulic and / or pneumatic actuation actuating fluid is guided in channels, which are formed by in the respective profiles already existing cavities, the additional effort for the realization of the hydraulic and / or pneumatic actuator is reduced to a minimum, especially as the previously required angle drives omitted. The previously occurring disturbing friction are avoided, which in particular results in a more reliable operation of the fitting arrangement. The operating fluid leading channels of the respective profiles can easily, for example, by appropriate welding or welding together of individual profile parts sealed on the outside. In addition, a respective adjustable fitting element can now be used at any point in the profiled wing frame or the fixed profiled frame and connected there to supply with actuating fluid with at least one actuating fluid channel leading the respective profile.

It is particularly possible that only one annular circumferential channel is provided, which is connected in a similar manner with both sides of the locking element. A changeover between the different operating states of the fitting arrangement can then be brought about by a reversal of the flow direction of the actuating fluid in the channel.

Advantageously, the actuating device comprises at least one pump, via which the actuating fluid for switching the fitting arrangement between the different operating states can be acted upon accordingly. In this case, for example, by switching the pump, the flow direction of the actuating fluid can be changed to effect switching between different operating conditions.

Alternatively or additionally, however, the actuating device may also comprise at least one piston, via which the actuating fluid for switching the fitting arrangement between the different operating conditions can be acted upon accordingly. Depending on the direction in which the piston is moved, one or the other operating state of the fitting arrangement can be brought about.

The actuating fluid can in particular in at least one through a cavity of the profiled wing frame or profiled fixed Frame formed in particular circumferential, closed channel to be performed. For example, in the event that the fitting elements to be adjusted are biased by spring force in one direction, a single such circumferential, closed channel is sufficient. Thus, a respective adjustable fitting element is held at a pressureless operating fluid by the spring force in the one operating position, while it is spent against the spring force in the other position under pressurized actuating fluid. In addition, in the case of only one such channel, switching between the different operating states can take place by correspondingly switching over the hydraulic pump or the piston for reversing the direction of flow in the channel. In this case, the spring loading can also be dispensed with, since the adjustable fitting element can be "sucked back" into its original position by the actuating fluid in this case.

As already mentioned, the locking element can be biased by spring force in one direction and be acted upon by the hydraulic and / or pneumatic actuator via the actuating fluid against the spring force. Instead of or in addition to the spring force can also be a "sucking back" of the locking element by the actuating fluid.

However, as also already stated, it is also conceivable that the locking element for switching between different positions on the actuating fluid can be acted upon in opposite directions. In this case, for switching between the different positions, for example, the pump can be switched accordingly or the actuating fluid can be acted upon by the piston in the opposite direction.

Advantageously, the base of the locking element is provided with indentations or the like and can be inserted into the groove, for example, such that two edge regions of the groove which partially overlap the groove engage with these recesses in order to position the sock in the groove.

In the case of the arrangement of the locking element on the fixed frame this can also be fixed there as described in the respective groove and connected to the at least one actuating fluid channel leading the respective profile. As already mentioned, however, the locking elements are preferably arranged on the casement and the closing parts on the fixed frame.

The different operating conditions, between which the fitting arrangement by means of the hydraulic and / or pneumatic actuator is switchable, in particular a closed operating state, in which the wing is closed and locked to the fixed frame, and at least include an open operating state, in which the wing is released in particular for a rotary opening or tilting.

According to a further advantageous embodiment of the fitting arrangement according to the invention, this comprises a positive guide, via which a tilting device is drive-effectively coupled to the hydraulic and / or pneumatic actuator so that the wing by means of the hydraulic and / or pneumatic actuator tiltable and from the tilted position back into the Closed position is convertible.

Preferably, the profiled fixed frame and / or the profiled wing frame at least substantially made of plastic and in particular of an extruded profile.

Fig. 1 shows in perspective, partially cutaway view of an exemplary embodiment of a hydraulic fitting assembly 10 according to the invention for windows, doors or the like. Although the invention is described below purely by way of example with reference to a hydraulic fitting arrangement, the invention can also be realized as a pneumatic fitting arrangement.

The relevant window or door comprises a fixed frame 12 and a wing, of which in the present case only part of the Sash 14 is shown. The fixed frame 12 and the sash 14 are each profiled. They can each consist at least substantially of plastic and in particular each be formed by an extruded profile. In the Fig. 1 are also arranged in the respective fold facing each other grooves 16 and 18 of the fixed frame 12 and the sash 14, between which the so-called rebate air is located and in which parts of the fitting assembly 10 are arranged. Moreover, in this Fig. 1 to recognize the sash 14 associated receptacle 20 for a window seal.

The fixed frame 12 and the sash 14 are each profiled. In particular, they can each consist at least substantially of plastic and in each case be formed in particular by an extruded profile.

The fitting assembly 10 is switchable between different operating conditions. For this purpose, the fitting arrangement 10 comprises a hydraulic actuating device 44 (cf. Fig. 2 ), by means of which it can be acted upon accordingly between different operating conditions via actuating fluid 22. This actuating fluid 22 is guided in at least one channel 24 formed by a cavity of the profiled sash frame 14 and / or in at least one channel 26 formed by a hollow space of the profiled fixed frame 12.

As based on the Fig. 1 can be seen, the actuating fluid 22, for example, both in the sash 14 and in the fixed frame 12 each at least partially in two adjacent, formed by cavities of the profiled sash frame 14 and the fixed frame 12 channels 24 and 26 in opposite directions Be guided flow directions. The different directions of flow in the two adjacent channels 24, 26 associated with the casement 14 and the fixed frame 12 are indicated by arrows.

The two adjacent, actuating fluid-carrying channels 24, 26 of the sash 14 and the fixed frame 12 may each be provided in particular in the region of the respective groove bottom. They are formed by cavities that are present anyway in the relevant profiles for weight reduction or for receiving metal reinforcements or the like.

In addition, the groove 18 of the sash 14, as shown by the Fig. 1 it can also be seen, two edge regions forming the shoulder shoulders 28, on which a cuff-rail is usually supported, the function of which is explained in more detail below for the present invention.

Fig. 2 shows a schematic sectional view of the hydraulic fitting assembly 10 in the region of a hydraulic pump 30 which is coupled to two adjacent, actuating fluid-carrying channels, which may again be the channels 24 of the sash frame 14 or the channels 26 of the fixed frame 12. The pump 30 can be used in particular in the respective groove 18 and 16 respectively. In this case, the pump 30 may be provided, for example, with cuts 32 or the like, in which engage, for example, when inserted into the groove 18 of the sash 14 whose edge portions 28 to position the pump within the groove.

About this hydraulic actuator 44 associated pump 30, the actuating fluid 22 for switching the fitting assembly 10 between the different operating conditions is acted upon accordingly. In this case, for example, by switching the pump 30, the flow direction of the actuating fluid 22 can be reversed.

Alternatively or additionally, however, the hydraulic actuating device 44 may also comprise at least one piston, via the actuating fluid 22 for switching the fitting assembly 10 between the different operating conditions is acted upon accordingly.

The actuating fluid 22 may in particular be hydraulic oil.

The actuating fluid 22 may be guided, for example, in at least one circumferential channel formed by a cavity of the profiled sash frame 14 and the profiled fixed frame 12, respectively.

The fitting assembly 10 may include at least one latch member associated with the wing and / or at least one latch member associated with the stationary frame 12, each cooperating with an opposing latch member associated with the fixed frame and the wing respectively with the latch member and / or the latch member opposite thereto Closing adjustable and for adjusting by means of the hydraulic actuator 44 via the actuating fluid 22 is acted upon accordingly. Preferably, the wing or its sash 14 adjustable latch members and the fixed frame 12 fixed locking parts are assigned. In principle, however, the fixed frame 12 can be associated with locking elements be. In addition, in particular also both the wing and the fixed frame 12 each locking elements and both the wing and the fixed frame 12 each be associated with closing parts.

A respective adjustable locking element, for example, biased by spring force in one direction and be acted upon by the hydraulic actuator 44 via the actuating fluid 22 against the spring force. In particular, in the event that the wing frame 14 or the fixed frame 12 are each assigned exclusively by such a spring biased in one direction adjustable fitting elements, it is sufficient if the actuating fluid 22 in only one through a cavity of the profiled wing frame 14 and the profiled fixed Frame 12 is formed in particular circulating, closed channel is guided. In this case, a respective adjustable fitting element is acted upon by the spring force in one direction and thereby spent in the one switching position, while it is acted upon by the actuating fluid 22 against the spring force in the other direction and thereby adjustable in the opposite switching position. Instead of or in addition to the spring force, the reset of the locking element can also be effected by a corresponding "suction" of the locking element by the actuating fluid. With a completely circumferential channel, the locking element can also be moved by switching the flow direction of the actuating fluid in the respective desired position by the actuating fluid is pressed alternately from two opposite sides against the locking element.

If, however, a respective adjustable fitting element is connected to two adjacent, actuating fluid-carrying channels in which the actuating fluid flows in opposite directions, so At the same time, one side of the fitting element can be connected to one and the opposite side of the fitting element to the other channel, whereby the fitting element can be acted upon in opposite directions by the two fluid streams. An adjustment of the locking element is achieved in this case by appropriate mutual activation of the actuating fluid in the two channels.

It is also possible that only one annular circumferential hydraulic channel is provided, which is connected in a similar manner with both sides of the locking element. An adjustment of the fitting element is achieved in this case, that the flow direction of the actuating fluid 22 is reversed.

Fig. 3 shows a schematic representation of an adjustable locking element 34 with a base 36 and a relative thereto displaceably mounted locking pin 38. In this case, the base 36 of such adjustable locking element 34, for example, in the groove 18 of the profiled wing frame 14 are used, as shown in the Fig. 4 is shown schematically. The locking pin 38 can in particular be acted upon by a hollow screw 40 and at least one pressure chamber of the base 36 with actuating fluid 22 which is in fluid communication with a channel formed by a cavity of the profiled wing frame 14, actuating fluid 22 leading channel 24.

Is the sash frame 14, as in Fig. 1 shown, for example, provided with two channels 24 in which the actuating fluid flows in opposite directions, so for example a channel via the screw 40 with a pressure chamber on one side of the adjustable locking pin 38 and the other channel via a further hollow screw 40 with a pressure chamber provided on the opposite side of the locking pin 38 are in fluid communication.

A corresponding locking element 34 can also be arranged, for example, in the groove 16 of the fixed wing and via whose actuating fluid-carrying channels 26 are acted upon accordingly.

The 4 and 5 show in a purely schematic representation of an inserted into the groove 18 of the sash 14 adjustable locking element 34 which is acted upon by the two channels 24 in the manner described with actuating fluid 22.

A respective pressure chamber of the base 36 of such an adjustable locking element 34 can, in particular, via a self-sealing hollow screw 40 serving to fix the base 36 in the groove 18 of the profiled wing frame 14 (cf. Fig. 3 ) are brought into fluid communication with the respective, formed by a cavity of the profiled sash frame 14, actuating fluid channel 24 leading.

Includes the sash 14, as in the present embodiment, two adjacent actuating fluid-carrying channels 24, so in particular two self-sealing hollow screws 40 may be provided to connect the two fluid chambers of the pressure chambers of the base with these channels. For better clarity are in Fig. 4 the two in the drawing plane one behind the other channels 24 partially broken, a left and a right in the figure shown. Each of the channels 24 is connected via a respective hollow screw 40, each with a pressure chamber of the locking element 34.

The base 36 of the locking element 34 may, for example, as in the Fig. 2 shown hydraulic pump 30 is provided with cuts 42 or the like and be used in the groove 18 that two the groove 18 partially overlapping, shoulders forming edge regions 28 (see. Fig. 1 ) of the groove 18 with these cuts 42 engage to position the socket 36 in the groove 18.

As already mentioned, the locking element 34 can in particular be fixed in the groove 18 by means of at least one self-sealing hollow screw 40, via which the fluid connections between a respective actuating fluid-carrying channel 24 and the relevant pressure chamber are simultaneously produced.

If the fixed frame 12 are assigned adjustable locking elements, they can optionally be used in the same way in the groove 16.

In particular, the different operating conditions of the fitting assembly 10 may include a closed mode of operation in which the sash is closed and locked firmly to the fixed frame 12 and at least one open mode of operation in which the sash is released, in particular, for a pivot opening or for tilting.

In addition, the fitting assembly 10 may comprise a positive guide, via which a tilting means is drive-effectively coupled to the hydraulic actuator 44 so that the wing by means of the hydraulic actuator 44 is tiltable and from the tilted position back into the closed position can be transferred.
