Definitions

  • the invention relates to a fitting for a window, in particular a casement window, with the features of the preamble of claim 1. Furthermore, the invention relates to a window, in particular a casement window, with such a fitting.
  • Windows with a rotating sash or a rotating / tilting sash are known from the prior art. This means that the sash to be opened is attached to a frame via a pivot bearing or a pivot / tilt bearing. Opposite the bearing side, a handle element is generally attached to the wing, which is operatively connected to a gear for actuating a locking device. By changing the grip position of the grip element, the locking device is locked or unlocked. With the help of the locking device, the window can thus be secured against unauthorized opening.
  • a locking device for a window generally has at least one pin which can be brought into engagement with a pin receptacle arranged on the frame by means of the gear mechanism. In this way, a positive connection that is effective in the opening direction of the window is achieved via the pin engaging in the pin receptacle.
  • the pin can be designed in such a way that it engages behind the pin receptacle, at least in sections, so that an additional positive engagement perpendicular to the direction of movement of the pin is achieved.
  • the closure device comprises a spring catch, by means of which the sash can also be fixed to the frame.
  • the drive rods of the gearbox can be moved into three different switching positions. In two of the three switching positions, the spring catch can be brought into locking engagement with an associated locking frame-side locking piece, while all the other locking elements can only be put into locking engagement with their respective locking pieces in one of these two switching positions.
  • the present invention is based on the object of specifying a fitting for a window which not only meets the current requirements of the Energy Saving Ordinance (EnEV) with regard to air permeability or tightness, but also fulfills fire protection requirements.
  • a window equipped with such a fitting should in particular be certifiable as a fire protection closure.
  • the proposed fitting for a window comprises a gear, a first locking device which can be actuated by the gear and a second locking device which can be actuated by the gear, the first locking device at least one pin which can be brought into engagement with a pin receptacle and the second locking device at least one in Has engagement with a snap catch bringable spring catch.
  • the fitting further comprises a handle element which is operatively connected to a gear rod of the gearbox for actuating the gearbox and is movable in at least three handle positions A, B, C. In the handle position A both locking devices are activated, in the handle position B only the second locking device is activated and in the handle position C both locking devices are deactivated.
  • the transmission comprises at least one return spring for the automatic return of the handle element from the handle position C to the handle position B.
  • the handle element is automatically returned to a handle position in the return spring, in which the spring catch is reactivated after deactivation (handle position C) (handle position B).
  • the return spring thus not only ensures that the window closes automatically, but also remains closed until the handle element is moved into the handle position C again.
  • a window can thus be upgraded to a fire protection element, since it fulfills the requirements of self-closing and positive locking.
  • the positive locking device cannot be disengaged or disengaged by pressing on the sash of the window. To do this, the handle element must be activated actively, against the spring force of the return spring.
  • the spring force of the return spring is designed to be sufficiently strong that it can return the grip element to the grip position B.
  • the handle position B is preferably arranged between the handle position A and the handle position C, and preferably still closer to the handle position C than to the handle position A.
  • the handle element has an elongated olive or handle, this is preferably oriented vertically in the handle position A and preferably horizontally in the handle position B. In order to move the grip element from grip position A to grip position B, the olive or the handle must therefore be rotated by 90 °. In order to move from the handle position B to the handle position C, the handle element must be rotated further in the same direction of rotation, but preferably by less than 90 °, further preferably by less than 60 °.
  • the fitting can be designed such that a rotation of 45 ° is sufficient to move the grip element from grip position B to grip position C.
  • the restoring spring is directly or indirectly operatively connected to the gear rod, so that the restoring force of the restoring spring can be transmitted to the handle element via the gear rod.
  • the restoring force of the restoring spring is preferably converted into a restoring moment, since the operative connection between the grip element and Gear rod is preferably such that a rotational movement of the handle element leads to a displacement of the gear rod or a displacement of the gear rod leads to a rotational movement of the handle element.
  • a corresponding operative connection between the grip element and the gear rod can be established, for example, via a nut gear.
  • the restoring force required to reset the grip element can be achieved with the aid of a single return spring.
  • a single return spring is therefore preferably provided.
  • the one return spring is preferably arranged separately from the two locking devices on the gear rod or on a gear rod extension connected to the gear rod, so that there is a direct or indirect operative connection between the return spring and the gear rod.
  • the return spring can be arranged in the extension of the gear rod.
  • one end of the return spring is preferably connected to one end of the gear rod or one end of a gear rod extension.
  • the direction of movement of the gear rod or the gear rod extension corresponds to the tensioning direction of the return spring. This means that the return spring is tensioned when the gear rod or the gear rod extension is moved by actuating the handle element.
  • the return spring be arranged parallel to the direction of movement of the gear rod or a gear rod extension.
  • the parallel arrangement also ensures that the return spring is tensioned by a movement of the gear rod or the gear rod extension.
  • the parallel arrangement has the advantage that the position of the return spring on the gear rod or on the gear rod extension is largely freely selectable and can thus be optimally adapted to the respective installation space conditions.
  • the return spring is preferably tensioned when the handle element is transferred from the handle position B to the handle position C.
  • the tensioning of the return spring leads to an automatic return of the handle element to the handle position B as soon as it is released.
  • the return spring is advantageously designed as a tension spring, in particular as a coil tension spring.
  • the tension spring or screw tension spring has the advantage that it does not require any guidance, since - unlike, for example, a helical compression spring - there is no fear of buckling under load.
  • the at least one spring catch of the second locking device is operatively connected to the gear rod and / or to a gear rod extension.
  • This means that the spring catch can also be operatively connected directly or indirectly to the gear rod.
  • An active connection with the handle element is in turn established via the direct or indirect operative connection to the gear rod. The second locking device can thus be deactivated by actuating the handle element.
  • the position of the at least one spring catch can largely be chosen freely. Furthermore, several spring catches can be arranged evenly distributed, which has proven to be an advantage, particularly for large window sashes.
  • a gear rod extension is provided, it is preferably aligned at an angle to the gear rod and connected to it via a deflection device.
  • This enables the at least one spring catch to be arranged in a corner with respect to the gear rod, so that the spring catch does not necessarily have to be arranged in the region of a main closing edge of a window sash, but also in the region of a secondary closing edge can.
  • the main closing edge of a wing is usually defined by the position of the handle element. These are usually connected by two secondary closing edges, each of which runs perpendicular to the main closing edge in the case of a rectangular wing. If at least one spring catch is arranged in the area of at least one secondary closing edge, this area can also be additionally secured by a positive locking. This is particularly useful if the window sash has a certain width.
  • the return spring can be arranged in an extension of the gear rod at one end of the gear rod or on a gear rod extension connected to the gear rod. If the gear rod extension is connected to the gear rod via a deflection device and is therefore arranged at an angle to the gear rod, "in extension" of the gear rod can also mean that the return spring is oriented at an angle to the gear rod.
  • the second locking device comprises at least two spring catches, which are operatively connected to different gear rod extensions, each connected to the gear rod via a deflection device.
  • two secondary closing edges of a wing can each be provided with at least one spring catch, for example two secondary closing edges opposite one another on the wing, in particular an upper and a lower secondary closing edge.
  • the spring catches located opposite one another on the secondary closing edges of a wing achieve an essentially symmetrical and thus optimal guard locking of the wing.
  • At least one pin of the first locking device is arranged at a distance from the at least one spring catch of the second locking device and the distance through Actuation of the gear is changeable. That is to say that the first and the second locking device can be actuated independently of one another, for example to deactivate the first locking device while the second locking device remains activated or to deactivate the second locking device while the first locking device remains deactivated.
  • the at least one pin of the first locking device is preferably connected to the transmission rod or to a transmission rod extension in a fixed or fixed position, while the spring catch is connected or operatively connected to the transmission in such a way that the transmission rod and / or the transmission rod extension can be moved without actuating the spring catch.
  • This is particularly advantageous if the handle element is transferred from the handle position A to the handle position B in order to deactivate the first locking device. The second locking device then remains activated.
  • an active connection of the spring catch is made with the gear rod and / or the gear rod extension, for example via a driver and / or a stop, so that the gear rod and / or the gear rods -Extension carries the spring catch to also deactivate the second locking device.
  • the distance between the at least one pin and the at least one spring catch which can be changed by means of the gear mechanism, can be measured along a single closing edge of the wing, and also cornerwise along a first and a second closing edge.
  • At least one pin of the first locking device and at least one spring catch of the second locking device on the same closing edge are preferred Wing arranged. Since the spring catch only has an additional locking function, an optimal seal can be achieved by the at least one pin on the same closing edge when the first locking device is activated. This is especially true if the wing is comparatively high and / or wide.
  • a plurality of pins of the first locking device are arranged distributed over the main closing edge and at least one secondary closing edge of the leaf, so that an optimal tight closure is achieved all around. The pins are then actuated via the gear rod and at least one gear rod extension.
  • the spring catch comprises a locking element which is mounted in a reciprocating manner and is preloaded by means of the spring force of a spring and which can be brought into engagement with a locking receptacle.
  • the locking element can in particular be designed analogously to a latch in a door lock.
  • the bolt catch takes over the function of the striking plate. If the locking element engages with the locking receptacle, a positive connection is achieved, which preferably acts in the opening direction of the leaf and thus prevents unintentional or unauthorized opening.
  • the locking element is similar to the case of a door lock.
  • the locking element preferably has a run-up slope that faces the lock receptacle, so that when the run-up slope strikes the lock receptacle, the locking element is pushed back against the biasing force of the spring. This facilitates the production of the positive connection and at the same time promotes independent closing.
  • a run-up slope can be formed in the area of the bolt receptacle.
  • the latch holder is preferably formed within the catch holder. In this way, a double positive connection can be produced. A first positive locking is achieved when the wing is closed by the Spring catch engages in the catch holder. A second positive connection is then achieved in that the locking element falls into the locking receptacle. While the second form fit acts in the opening direction of the wing, the first form fit preferably acts perpendicularly to it, that is to say in the plane of the wing.
  • the spring catch comprises a housing in which the spring-loaded locking element is mounted to move back and forth and is supported on the housing via the spring.
  • the locking element can be guided via the housing.
  • the locking element is preferably accommodated in the housing in such a way that the section to be brought into engagement with the locking receptacle, preferably the section with the run-on slope, protrudes from the housing.
  • the locking element is first pushed further into the housing of the spring catch against the spring force of the spring that biases the locking element, and then then falls into the bolt receptacle.
  • the spring catch must first be brought into engagement with the catch receptacle. Only then can the locking element be brought into engagement with the locking receptacle.
  • the outer contour of the housing is preferably adapted to the inner contour of the catch holder.
  • the spring catch is connected to a faceplate of the transmission via the housing.
  • the faceplate is usually used to cover a gear rod and / or a gear rod extension of a gear. This means that the faceplate is placed on the outside of the sash.
  • the faceplate is therefore particularly well suited for the arrangement and attachment of the spring catch.
  • the faceplate also does not cause any movements an actuation of the handle element, so that the position of the spring catch relative to the catch receptacle does not change. This ensures that when the wing is closed, the spring catch hits the catch holder that is fixed to the frame.
  • the housing of the spring catch can be fastened to the faceplate by means of a screw connection.
  • the locking element Since the position of the housing of the spring catch is preferably unchangeable, the locking element must be moved relative to the housing in order to deactivate the second locking device. This presupposes that there is an operative connection of the locking element with the transmission.
  • the locking element of the spring catch has a guide pin which extends perpendicular to the direction of movement of the locking element and engages in a guide of the transmission.
  • the necessary operative connection for actuation, in particular for deactivating the spring catch or the second locking device can then be established via the guide pin engaging in the guide when the grip element is transferred from the grip position B to the grip position C.
  • the guide of the gear in which the guide pin engages, is preferably designed as an elongated hole, so that the operative connection between the spring catch and the gear is only established in two ways.
  • a deactivation of the spring catch or the second locking device is preferably only desired when the handle element is brought from the handle position B to the handle position C.
  • the execution of the guide as an elongated hole ensures the required degrees of freedom.
  • the operative connection between the spring catch and the gear is preferably achieved by a stop edge that delimits the guide.
  • the locking element of the spring catch which has the guide pin, is actuated by the gear or carried by the gear rod and / or the gear rod extension which forms the guide.
  • the locking element is pulled or pressed against the spring force of the spring biasing the locking element out of the locking receptacle.
  • the locking element having the guide pin is accommodated at least in sections in a housing of the spring catch and / or the gear rod or gear rod extension, which forms the guide, is covered by a faceplate, the effective connection between the spring catch and the gear must be made on the locking element arranged guide pins are designed and arranged such that it extends through the housing and / or the faceplate.
  • the housing and / or the faceplate therefore preferably has a recess through which the guide pin can be guided.
  • the recesses are preferably designed as an elongated hole, so that it is further ensured that the guide pin comes to rest against the stop surface of the guide formed in the gear rod or in the gear rod extension.
  • a window in particular a rotating casement window, is therefore also proposed, which comprises a window frame and a sash that is rotatable relative to the window frame for opening and closing the window and a fitting according to the invention arranged between the window frame and the sash.
  • the window is upgraded to a fire protection window by the fitting according to the invention, which not only meets the current tightness requirements according to the current Energy Saving Ordinance (EnEV), but also meets applicable fire protection requirements.
  • EnEV Energy Saving Ordinance
  • the fitting according to the invention enables the realization of a self-closing window, which is held in a form-fitting manner in the closed state. This is because the handle element provided for deactivation is automatically reset by the transmission to a handle position in which the deactivation of the second locking device is canceled or the second locking device is activated. The second locking device cannot be deactivated without the active actuation of the grip element again.

  • the design as a helical tension spring has the advantage that the return spring 12 - in contrast to a helical compression spring - cannot buckle under tension or load. It depends on the direction of movement of the gear rod 11 and the gear rod extensions 13 where the coil tension spring is to be arranged in the gear 3. The arrangement must be such that it is ensured that the return spring 12 is tensioned when the second locking device 5 is deactivated. Only then can the second locking device 5 be regarded as "self-closing" in the sense of the fire protection regulation.
  • Fig. 19 shows that the gear rod 11 is connected at its lower end via a deflection device 14 to a gear rod extension 13, so that when the gear rod 11 moves downward, the gear rod extension 13 is shifted to the right.
  • recesses 30 for this purpose are formed analogously to the recess 28 for the guide pin 19 of the locking element 15.
  • Fig. 21 transfers the handle element 10 from the handle position B to the handle position A, the gear rod extension 13 moves to the left and with it the pins 7, so that these are brought into engagement with the pin receptacles 6 (in the Fig. 21 not shown).
  • the second locking device 5 is not actuated because the guide pin 19 of the locking element 15 does not come to rest against the stop edge 29 of the guide 20 formed in the gear rod extension 13.
  • a distance a between the pin 7 and the spring catch 9 increases.
  • Fig. 23 is an exploded view of another window 2 with a fitting 1 according to the invention, which differs from the fitting 1 described above in particular by the position of the return spring 12.
  • the return spring 12 is not arranged this time in the area of a secondary closing edge 25, but in the area of the main closing edge 23, in a recess 42 of the leaf 22. In this way, space is created in the area of the secondary closing edge 25 for a closer 35, which with the window open 2 automatically transfers the sash 22 back into the closed position, so that the window 2 is self-closing.
  • the window 2 of the Fig. 23 is analogous to window 2 Fig. 1 shown, that is, that also in the Fig. 23 overlay different views or profile cross sections are shown in the views.
  • the fitting 1 of the window 2 of the Fig. 23 again has a gear 3 with a gear rod 11 and gear rod extensions 13 connected at each end to the gear rod 11 via a deflection device 14.
  • the gear rod 11 and the gear rod extensions 13 are equipped with pins 7 of a first locking device 4, which can be brought into engagement with pin receptacles 6 of the frame 21.
  • the gear rod extensions 13 also each have a spring catch 9 of a second locking device 5, which engages with a catch holder 8 of the Frame 21 can be brought.
  • the functioning of the two locking devices 4, 5 corresponds to that of the window 2 described above, so that in this regard the description of the 1 to 22 is referred. In the following, only the changed arrangement and configuration of the return spring 12 will be discussed.
  • the return spring 12 received in the recess 42 of the wing 22 is designed as a helical tension spring.
  • a first end of the return spring 12 is operatively connected to the transmission rod 11 via a fastening element 36, which in the present case is designed as a screw, in such a way that the return spring 12 is carried along when the transmission rod 11 moves.
  • the return spring 12 is only tensioned when the grip element 10 moves out of the grip position B (see Fig. 26 ) in the handle position C (see Fig. 27 ) is transferred.
  • the return spring 12 is fixed on the wing 21 via a guide rail 37 and a fastening element 39 which engages in an elongated hole 40 of the guide rail 37, so that the return spring 12 and the guide rail 37 can move relative to the wing 21.
  • the return spring 12 is only tensioned when the fastening element 39 comes to rest on the guide rail 37 (see Figures 26 and 27 ).
