Description

The invention relates to a device for a window or a door according to the preamble of claim 1. In particular, the invention relates to devices for Drehkippflügel-, rotary wing, Kippflügel- or Parallelabstellflügel- for windows or doors. In the following, the part to be opened and closed will be referred to as a wing and the part fixed to it as a frame.

The device has the task by the opening and closing support to support the wing to the frame from a closed position or from an opening end position and to generate a damping during movement in the closed position and in the opening end position. This can be when opening, for example, in the opening end position for tilting and closing the wing from the tilted opening end position in the closed position, control the opening speed and adversely affect forces and impact noises occurring on the fitting. The occurring forces of such a system are dependent on the initial speed and the mass, so that in particular large-scale windows or doors can burden the espagnolette fitting and cause loud stop noises in the opening end position and closing position. The large weight of the wing also complicates the closing process from the opening end position. Therefore, it is further desired to ensure by the use of the easy-to-install device to facilitate the closing process from the opening end position in the applied closed position and from the closed position to the opening end position.

In particular, when opening in the opening end position for tilting and closing the wing from the tilted opening end position in the closed position, the necessary manual force for the execution of the tilting of the wing is neglected by frictional influences by the handle height, wing mass and position of the blade center of gravity with respect to the tipping point. The displacement of the position of the center of gravity of the wing with respect to the tipping point of the wing, at the lower horizontal beam of the wing to the frame, during tilting, causes a reversal of the operating force on the operating handle. If the center of gravity of the wing is located on the outside in relation to the tipping point for an inwardly opening window, the execution will be made from the position in which the wing is in the closed position relative to the frame Out in the tilted opening end position first a train and then a pressure operator required. For the closing of the wing from the tilted opening end position in the direction of the closed position to the frame, first a pressure and then a Zugbedienkraft are required.

As already stated, the invention relates to a device which is used as a relief and assistance in the operation of the window or the door from the closed position to the opening end position and vice versa in the closed position of the wing. In these applications, fittings are known that forward via espagnolette and corner deflections an actuating movement of an operating lever over more than one or all sides of the wing to lock at several distributed the wing circumference by closure devices locking and by a display device a rotational and / or Kippöffnungsstellung the Wing against the frame effect.
In these areas, an increased demand for comfort is increasingly recognizable. To meet these requirements, the functional scope of the components of the assembly is to be increased.

A fitting part of this kind is by the DE 2001369 A1 already known. The known device makes it possible to facilitate the opening and closing of windows and doors, which consists of a pivot arm arranged between the pivotable part and a sliding guide. For this purpose, the device is attached to an inner side wall of a frame part resting, wherein a pivoting arm connects a wing articulated. The other free end of the pivot arm is rotatably mounted with a slidable in the device of a guide slider. Between the slider and one end of the guide an elastic means is arranged, which counteracts the tendency of the wing when tilting down to counteract, wherein the wing rotates about a hinge and the elastic element generates a counterbalance.

By these measures, the movement of the closed position of the wing out of the frame in the Kippöffnungsendlage, ie from the vertical position of the wing in the Kippöffnungsendlage by a person opening the wing, the weight to be mastered and the relatively high fall speed can be reduced. However, a lot of space is required for this feature according to the known device, so that the device can only be mounted resting on the frame. The device is limited only to the steaming in the Kippöffnungsendlage. A device for adjusting the speed of fall through the device due to different forces occurring, resulting from the displacement of the center of gravity of the wing during tilting or by different weights of the window or door, is not read from the aforementioned device. Furthermore, from the EP 0960999 A1 a fitting known, which has a Ausstellschere for a tilting window with a stay, which runs with a pin in a rail. The pin is pressed by a spring means against the closed position. The spring means causes a partial opening of the window sash in the tilted position. Furthermore, the spring means is to brake the wing in the tilting position.
However, while the weight and the fall speed in the Kippöffnungsstellung a window or a door are ignored in particular when opening the wing by a person, so that the spring means due to the load and the installation space can not muster the required force to brake the wing in the tilted position. The device is limited only to the damping in the Kippöffnungsendlage and has no means for adjusting the device for damping.

Reference is also made to the WO 2013/135545 A1 , comprising a combined device for decelerating and accelerating a wing of windows or doors, and an espagnolette drivable in a fitting groove and in a folding room, which includes an opening scissors. The opening width of the Ausstellschere is limited in a tilting position by a pivotally hinged on the one hand on the frame and the other hand on the wing pivot arm by this engages with a pin or the like. In a longitudinal guide of the espagnolette fitting. The longitudinal guide forms at its Kippöffnungsendstellung the wing end facing a limit stop for the pin. The device is concealed in the rebate and / or the fitting groove between the frame and the wing mountable. An arranged on the device pull rod forms the movable coupling with the pivot arm, which is arranged on the frame with a hinge movably coupled Ausstellschere, acting between the tie rod and the pivot arm in the longitudinal direction of the fitting groove, a force storage. The energy storage counteracts the movement of the wing in the Kippöffnungsendstellung, so that a slowed movement of the wing is effected. Furthermore, the wing from the securely held Kippöffnungsendstellung - with the release of the stored force of the energy storage - accelerated and transferred almost automatically in the closed position.

The device described above can indeed concealed in the rebate of the window or door mount and is only suitable to accelerate the wing in the Kippöffnungsendstellung to damp or brake and the wing from the Kippöffnungsendstellung with release of the stored force of the energy accumulator and in the To transfer closure position. However, the known device has no adjustment for regulating the force components for damping and accelerating.

The known devices are not suitable to regulate different weight forces arising from different sizes of windows and doors, for example, the falling speed in a tilting operation. An adjustable on the wing of a window or door device that controls when tilting in an opening end position or when closing the wing from the tilted Öffnungsendlage in the closed position, the opening speed and thus adversely affects the fitting forces and impact noises, goes from the known devices not apparent. The disadvantage here is that the device for small sash weights can overload the wing too high and can show a barely noticeable effect with large sash weights, which affects the operation of the window or the door rather than disturbing.

The invention has for its object to provide a device for opening and closing support of the wing to the frame from a closed position, and from an opening end position, and to allow a damping of the movement in the closed position and in the opening end position, with a possibility for regulating the movement the opening and closing assistance and the damping to eliminate the above disadvantages.

To achieve this object, a combined deceleration and acceleration device is provided which, to assist and facilitate the opening and closing of a wing of a window or door, acts at least one between a frame and the wing of the window or the door for opening and closing support Having spring device, and is operatively connected to a Ausstellschere whose opening width can be limited in an opening end position by a hinged on the one hand on the frame and on the other hand on the wing extension arm.

For this purpose, the spring device has an adjusting device for spring stiffness. To adjust the spring stiffness, the active spring length is changed with the actively loaded turns in the opening pivot position or closing pivot position or between the transition point of the opening to closing support. Based on an equation or diagram depending on the position of the center of gravity of the wing and its mass, the setting of the active windings for the spring stiffness can be determined and adjusted.

Likewise, the spring preload can also be adjusted via the adjusting device. The determination of the setting of the spring bias of the spring means is either using an equation or diagram if the position of the center of gravity of the sash is known. Alternatively, the setting of the spring preload, for example, in a tiltable wing by a tilt test, determine.
The adjustability of the spring stiffness and spring bias by the adjuster and / or the biasing device causes additional comfort in the device, to regulate the operation of small and large and heavy wings during tipping, or during a turning or stopping. The manual force on the actuating handle, for example, to perform the tilting operation is reduced. For this purpose, the force resulting from the displacement of the center of gravity of the wing during the tilting process is stored in the spring device. The previously stored spring force supports and reduces the necessary manual force on the actuating handle for performing the tilting operation. In addition, a reduction of the dynamics of the wing succeeds by the optimal damping effect of the spring means on the wing in the direction of the closed position and the opening end position. The damping effect also reduces the loads on the espagnolette fitting components, in particular the hinge components, the window or the door.

Advantageously, the device is used in turn, tilt or turn-tilt windows or doors their use. It is also conceivable to mount the device in Parallelabstellfenster or doors.

By adjusting by means of the adjustment, thus, the number of turns of the compression spring is divided into a number of active turns and a number of inactive, passive turns.

Simple to manufacture and inexpensive, and easy adjustability of the spring stiffness and spring preload is achieved in that the adjusting device has a blocking element which consists of a Klipsring, snap ring, split pin or other known connection components. The Klipsring, snap ring or split pin passes through a predetermined distance having free space between the turns of the compression spring, the clip ring or snap ring engage in the round rod gradual grooves arranged or infinitely, spindle-like grooves and the sapwood on the round rod arranged holes and form a and / or force-locking connection effect.

A further advantageous embodiment of an adjustment, with which the spring stiffness can be adjusted, consists of a threaded spindle or threaded rod, which rotatably guided with a free end with a fixed in Wirkverlängerung the sleeve on the faceplate Ausstellschere web through a through hole or through another through hole , at the through hole with each from both sides of the Web arranged nuts is positively connected. In this case engages at the other free end having head by means of external windings between the turns of the compression spring on the inside, wherein by a head of the free end having tool engagement, preferably a hexagon socket, by means of a tool by loosening the nuts depending on the direction of the threaded rod, the distribution of turns in active turns and inactive, passive turns causes.

Further simple and cost-effective embodiments for achieving an adjustment of the spring preload are achieved by the biasing devices shown in the spring device.

It is functionally advantageous in this case that by means of the biasing means, the distance between the first hinged end and the second hinged end of the spring device having compression spring is adjustable.

A first advantageous embodiment of the biasing means consists of a threaded pin, the form-fitting and / or non-positively, for example, by a retaining ring, held and rotatably supported by meshing with a paragraph in a bore forms a first coupling point, and with a second tapered in cross-section Journal in a receiving bore of the round rod in the longitudinal direction leading slidably having the second coupling point, wherein the threaded pin and the round rod form a central axis.

For easy adjustment of the biasing device, the threaded pin rotatably receives a threaded sleeve, which is operatively connected to the end of the compression spring and linear leader, for example, by a non-positively attached to the threaded sleeve dowel pin or dowel pin, mounted in a longitudinal direction of the faceplate elongated hole of the Ausstellschere , wherein the threaded pin at the coupling point to the driver facing out, a tool engagement preferably a hexagon socket, and by means of a tool causes an adjustment of the threaded sleeve, so that the distance of the compression spring can be changed.

To fulfill the function of the spring preload, a further advantageous embodiment of the biasing device is provided, which has a threaded spindle or threaded rod, which rotatably guided with a free end with a fixed in Wirkverlängerung the sleeve on the faceplate Ausstellschere web through a through hole, each with two Pages of the web arranged nuts is frictionally connected. An on the other free end having head engages by means of external windings between the turns of the compression spring inside, wherein a tool by loosening of the Compressed spring removed nut and turning the nut directed to the compression spring, depending on the direction of adjustment of the threaded rod, the compression spring by the threaded rod tensioned or relieved, is relaxed.

The simple coupling of the device to the espagnolette fitting and the fact that the device is designed as a unit independent of the espagnolette fitting, allows mounting with the espagnolette fitting or, if necessary, a subsequent mounting on the already pre-assembled espagnolette fitting.

In the FIG. 1 a device 1 is provided, which as a relief and assistance in the operation of the window or door 3 from the closed position to Fig. 4 in the opening end position Fig. 1 and vice versa in the closed position of a wing 2 to the frame 4 is used. In these applications, espagnolettes 77 are known which forward via espagnolette and corner deflections an actuating movement of an operating lever over more than one or all sides of the wing 2, at several the wing circumference distributed locations by locking devices a lock and by a display device a rotary and / or Kippöffnungsstellung or parallel shutdown of the wing 2 against the frame 4 to effect.

In these areas, an increased demand for comfort is increasingly recognizable, which is associated with increased safety awareness. To meet these requirements, the functional scope of the components of the assembly is to be increased.

This is after Fig. 1 to 3 the combined decelerating and accelerating device 1 for the wing 2 of windows or doors 3 provided to assist and facilitate the opening and closing of a wing 2 of a window or door 3 at least one between the frame 4 and the wing 2 of the window or the door 3 for opening and closing support acting spring means 5, and is operatively connected to a Ausstellschere 6 whose opening width is limited in an opening end position by a hinged on the one hand on the frame 4 and on the other hand pivotally hinged 2 Ausstellarm 7. In the closed position of the wing 2 to the frame 4 after 4 to 5 , The spring device 5, based on the unloaded state of the spring device 5 due to a first change in length 8 spring force acts stored and accelerates the wing 2 with movement of the stay 7 from the closed position of the wing 2 with removal from the frame 4 in the direction of an opening pivot position Fig. 2a and releases the stored spring force. Upon further change of the distance of the wing 2 to the frame 4 with movement of the extension arm 7 from the opening pivot position in the direction of a limited opening end position of the wing 2 after Fig. 1 to 3 , The spring force of the spring means 5, starting from the unloaded state of the spring means 5 at a second change in length 9 after Fig. 2b and Fig. 5 stored structurally, which opposite to the first change in length 8 is effective, so that the wing 2 is moved damping in the opening end position. In a reverse closing movement of the wing 2 with movement of the extension arm 7 from the opening end position Fig. 1 and 3 out, the stored energy of the spring device 5 is released and accelerates the wing 2 in the direction of a Schließschwenklage after Fig. 2a , With further movement of the extension arm 7 from the Schließschwenklage in the direction of the closed position of the wing 2 after Fig. 4 , the spring force of the spring device 5 is stored constructively, so that the wing 2 dampens the closed position.

Characterized in that the spring device 5 during the opening process from the adjacent closed position of the wing 2 to the frame 4 after Fig. 4 Relaxed out, energy is automatically released, supporting the opening of the wing 2 from the closed position in the direction of the opening pivot position Fig. 2a causes. Upon reaching the opening pivot position after 2a , the spring device 5 is relaxed and builds up with further actuation of the wing 2 in the direction of the opening end position, so that the spring device 5 after reaching the opening end position Fig. 1 and 3 the energy stores. With transfer of the wing 2 from the securely held opening end position, the stored energy discharges with relaxation of the spring device 5 to the Schließschwenklage after Fig. 2a , The relaxed spring device 5 is with further movement of the wing 2 from the Schließschwenklage in the direction of the closed position to Fig. 4 strained and builds up energy stored in the closed position. In opening pivot position and in Closing pivot position after Fig. 2a is the wing 2 to the frame 4 in a part open position, an intermediate layer or transitional position, with one of the spring means 5 relieved completely released energy.

The device 1 can be used in the operating modes of the wing 2 for a tilting, turning or shutdown, which will be discussed in more detail below on the tilting.

The manual force on the actuating handle, not shown, for example, to perform the tilting operation is reduced. For this purpose, the force resulting from the displacement of the center of gravity of the wing 2 during the tilting process is stored in the spring device 5. The previously stored spring force supports and reduces the necessary manual force on the actuating handle for performing the tilting operation. In addition, a reduction in the dynamics of the wing 2 by the optimal damping effect of the spring device 5 on the wing 2 in the direction of the closed position and the opening end position succeeds. The damping effect also reduces the loads on the espagnolette fitting components 77, in particular the hinge components, the window or the door 3.

For concealed fixing of the device 1 in the rebate space 11 and / or the fitting groove 10 between the frame 4 and the wing 2 after Fig. 1 and Fig. 4 , the device 1 in the dimensions, for example in the height of the in the rebate space 11 and / or the fitting groove 10 operatively arranged by the actuating handle arranged drive rod fitting 77 adapted. The device 1 is dimensioned in the cross-sectional dimensions and in the length so that an assembly requires no further processing on the window or the door 3. The functionally acting components of the device 1 are aligned in the longitudinal direction of the fitting groove 10 ( Fig. 4 ).

According to a first embodiment of the device 1, the spring device 5 after Fig. 1 to Fig. 6 a compression spring 12 as a helical compression spring, wherein the compression spring 12 acting in the longitudinal direction of the fitting groove 10, from the closed position to Fig. 4 the wing 2 out in the direction of the opening pivot position Fig. 2a is loaded on pressure and with movement of the stay 7 of the Ausstellschere 6 from the opening pivot position in the direction of the opening end position Fig. 1 of the wing 2 is loaded to train, with reverse closing movement of the wing 2 and movement of the stay 7 from the opening end position after Fig. 1 out in the direction of the closing pivot position Fig. 2a , Relaxed on train pressure spring 12, and the compression spring 12 is loaded with movement of the stay 7 from the Schließschwenklage in the direction of the closed position of the wing 2 to pressure.

For this, the compression spring 12 is after Fig. 3 actively operatively connected to the stay 7 of the stay-scissors 6, wherein a free end 13 of the compression spring 12 force and / or positive fit according to an embodiment of Fig. 3 and Fig. 6 turned on a pin 15 attached to the pin and a rotatable end 14 of the stay 7 are attached to a longitudinally displaceable hinged to the Ausstellschere 6 driver 15.

To Fig. 5 to Fig. 7 surrounds the compression spring 12 over the length of their turns 16 a rod 17 or is after Fig. 10 held by a outside of the windings 16 arranged sleeve 18 in the longitudinal direction of the fitting groove 10 leading dimensionally encompassing. The round rod 17 or the sleeve 18 is connected in a positive and / or non-positive manner to a faceplate 19 of the setting-out scissors 6 of the device 1 attached to the wing 2 in the direction of the fitting groove 10. The connection itself is not shown further, but can be achieved, for example, by a riveted connection. a screw connection or a connection can be created by a welding process.

To Fig. 5 to 6 and after Fig. 10 to 11 the spring device 5 has an adjusting device 20, 25 for spring stiffness. To adjust the spring stiffness, the active spring length is changed with the actively loaded turns 21 in the opening pivot position or closing pivot position or between the transition point of the opening to closing support. On the basis of an equation or diagram depending on the position of the center of gravity of the wing and its mass, the setting of the active windings 21 for the spring stiffness can be determined and adjusted.
Likewise, the spring preload can also be adjusted via the adjusting device 20, 25. The determination of the adjustment of the spring bias of the spring means 5 is carried out either by means of an equation or a diagram, if the position of the center of gravity of the wing 2 is known. Alternatively, the setting of the spring preload, for example, in a tiltable wing 2 by a tilt test, determine.

By setting by means of the adjusting device 20, 25, thus the number of turns 16 of the compression spring 12 is divided into a number of active, claimed turns 21 and a number of inactive, passive windings 22nd
To adjust the spring stiffness and the spring preload, the adjuster 20 after Fig. 5 to 6 a blocking element 23, which consists in this embodiment of a clip ring or snap ring. But there are also other connection components conceivable.
