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 shift of the position of the center of gravity of the wing relative to the tipping point of the wing, the lower horizontal spar of the wing to the frame, the tilting, causes a reversal of the operating force on the operating handle. If the center of gravity of the wing with respect to the tipping point for an inwardly opening window on the outside, is for execution from the located in the closed position of the sash to the frame location 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.

The device may also have the task of forming an additional escapement against the blade falling in a gust of wind, while acting as a safeguard against possible falling out of the wing.

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, which is associated with increased safety awareness. 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. Due to the arrangement of the individual components, in particular of the swivel arm and the sliding out of the guide slider, the device can not be integrated into a groove. Due to the superimposed visible variant, flat surfaces are interrupted and there are additional edges that are disadvantageous affect the appearance and cleaning. In addition, the device is limited only to the damping in the Kippöffnungsendlage. Further advantageous comfort operations are 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. Ostensibly, the device is limited only to the steaming in the Kippöffnungsendlage. Further advantageous comfort operations are not recognizable from the aforementioned device.

It is known to slow down the motion sequences in commercially used doors and gates and / or drive controlled in the end positions. The same applies to the area of passenger and commercial vehicles. These solutions operate pneumatically, hydraulically or electromechanically and are suitable for braking and / or dampening translational or rotational movements.

The devices for components in the form of sliding doors and partitions in interior design, are very expensive in construction, have a variety of components and are expensive to manufacture. A combination for accelerating from the situation located in the closed position of the sash to the frame out into the tilted, with damping opening end position and from the opening end position in the applied with damping effect closing position is not known.

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 rebate space, which includes an outrigger. 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.

Although the device described above can be mounted concealed in the rebate of the window or door, but the device proves to be expensive to manufacture and is only suitable to the wing in the Kippöffnungsendstellung to damp or brake and the wing from the Kippöffnungsendstellung with Accelerate release of the stored force of the energy accumulator and transfer to the closed position. The present embodiment of the espagnolette also allows no linear translation, which can affect the device in an advantageous manner.

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, the good optics of the window or the door is inexpensive and can be mounted in a simple, fast, safe and precise manner with little space and adjusted and eliminates 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 is spring-loaded in a closed position of the wing and accelerates the wing with movement of the extension arm from the closed position of the wing with removing the frame in the direction of an opening pivoting position and outputs the stored spring force. Upon further change of the distance of the wing to the frame with movement of the extension arm from the opening pivot position in the direction of a limited opening end position of the wing, the spring force of the spring device is stored constructively, so that the wing is moved damping in the opening end position. In a reverse closing movement of the wing with movement of the extension arm out of the opening end position, the stored energy of the spring device is released and accelerates the wing in the direction of a Schließschwenklage. With further movement of the extension arm from the closing pivot position in the direction of the closing position of the wing, the spring force of the spring device is stored constructively, so that the wing dampening reaches the closed position.

The fact that the spring device relaxes during the opening process from the adjacent closed position of the wing to the frame, energy is automatically released, which causes a support of the opening of the wing from the closed position in the direction of the opening pivot position. Upon reaching the opening pivot position, the spring device is relaxed and builds up with further actuation of the wing in the direction of the opening end position, so that the spring device stores the energy upon reaching the opening end position. With transfer of the wing from the securely held opening end position, the stored energy discharges with relaxation of the spring device into the Schließschwenklage. The relaxed spring device is tensioned with further movement of the wing from the closing pivot position in the direction of the closed position and builds up energy that is stored in the closed position. In opening pivot position and in closing pivot position, the wing is located to the frame in a partially open position, with a fully released energy of the spring device.

The comfort operation by the device thus facilitates the operation of the tilting operation in the case of large and heavy wings, wherein the device can likewise influence the turning or stopping operation in an advantageous manner. 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.

For concealed fixing the device in the rebate and / or the fitting groove between the frame and the wing, the device adapts advantageously to the dimensions, for example in height to the in the rebate and / or the fitting by the actuating handle operably arranged espagnolette , As a result, a compact and simple construction of the device is achieved. The device is dimensioned in the cross-sectional dimensions so that an assembly requires no further processing on the window or the door. In an advantageous development, the components on which the device is based, in particular the components for performing a functional actuation, are aligned in the longitudinal direction of the fitting groove.

In order to meet the requirements of acceleration and damping while maintaining a cost-effective design of the device, the spring device comprises a compression spring as a helical compression spring, the compression spring acting in the longitudinal direction of the fitting groove, claimed from the closed position of the wing out in the direction of the opening pivot position to pressure is and is claimed with movement of the extension arm of the Ausstellschere from the opening pivot position in the direction of the opening end position of the wing to train, with relaxed closing movement of the wing and movement of Ausstellarms from the Öffnungsendlage out in the direction of Schließschwenklage, relaxes the claimed compression spring, and the compression spring is loaded with movement of the extension arm from the closing pivot position in the direction of the closing position of the wing to pressure.

Positive and / or non-positively connected, the round rod or sleeve on a fortified in the direction of the fitting groove on the wing faceplate of the Ausstellschere the device.

According to a development, it is provided that the spring device has an adjustment 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 adjustment of the spring bias of the spring means is carried out either by means of an equation or a diagram, if the position of the center of gravity of the wing is known. Alternatively, the setting of the spring preload, for example, in a tiltable wing by a tilt test, determine.

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 , is connected to the through-hole with each arranged on both sides of the web nuts non-positively. 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 shoulder 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. A head having at the other free end, engages by means of external windings between the turns of the compression spring on the inside, wherein a tool by loosening the nut remote from the compression spring and turning the nut directed to the compression spring, depending on the direction of the Threaded rod, the compression spring tensioned or relieved by the threaded rod, is relaxing.

Another simple and inexpensive to manufacture embodiment of the spring device results from two compression springs as helical compression springs, acting in the longitudinal direction of the fitting groove, from the closed position of the wing to the frame out the first pressure-loaded compression spring in the direction of the opening pivot position emits the stored energy of the spring force and finally completely releases and wherein with movement of the extension arm of the Ausstellschere from the opening pivot position in the direction of the opening end position of the wing to the frame, the second relieved compression spring is subjected to pressure while storing energy building. With reverse closing movement of the wing to the frame and movement of the stay out of the Öffnungsendlage out toward a Schließschwenklage, the second loaded on pressure and energy stored compression spring relaxes completely, the first compression spring with movement of Ausstellarms from the Schließschwenklage towards closing position of the wing to Frame is loaded on pressure while storing energy building.

For simple and functional transmission of the pressure springs acting in the spring device, the compression springs are actively connected to the extension arm of the Ausstellschere, wherein the rotatable end of the extension arm is attached to a longitudinally displaceable hinged on the Ausstellschere the fitting groove driver. In addition, the compression springs are operatively connected, each having one end to a web of a driver depending on the opening position of the extension arm and are held by each arranged on a fixed to the faceplate stop fixations with the other other ends leader.

Conceivable is a combination of the design of the spring device, consisting of two compression springs as helical compression springs, with the present adjustment and biasing devices.

Another simple and economical to manufacture embodiment of the spring device is obtained by two tension springs as Schraubenzugfedern, the tension springs act in the longitudinal direction of the fitting groove. From the closed position of the wing to the frame out a first tensile loaded in the direction of the opening pivot position releases the stored energy of the spring force completely released, with movement of the extension of the Ausstellschere from the opening pivot position in the direction of the opening end position of the wing to the frame, the second relieved Tension spring is subjected to train while storing energy building. With reverse closing movement of the wing to the frame and movement of the stay out of the Öffnungsendlage out towards a Schließschwenklage, relaxes the second claimed to train and energy stored tension spring completely, the first tension spring with movement of the extension from the Schließschwenklage towards closing position of the wing to Frame is loaded on train and stores energy building.

For simple and functional transmission of the tension springs acting in the spring device, the tension springs are actively connected to the extension arm of the Ausstellschere, wherein the rotatable end of the extension arm is attached to a longitudinally displaceable hinged to the Ausstellschere the fitting groove driver. In addition, the tension springs are operatively connected, each having one end to a web of a driver depending on the opening position of the extension arm and are held by a respective attached to the wing faceplate pins with the respective other ends.

Conceivable is a combination of the design of the spring device, consisting of two tension springs as Schraubenzugfedern, with the present adjustment and biasing devices.

For easy design and connection of the device during assembly, form the spring device together with the adjuster, the biasing device and the Ausstellschere a structural unit. This is a clear separation of the device and the espagnolette fitting of the window or door. Nevertheless, the assembly of the device is maintained by a positive and / or non-positive connection. Due to the adapted dimensions of the device for espagnolette, this also creates an adaptable in its length to the espagnolette fitting device that can be mounted as needed on both the vertical spar or the horizontal spar of the wing. This allows the device, in particular the Ausstellschere, independently and in conjunction with a manually or motor-driven espagnolette fitting in the fitting and in the rebate arrange and secure.

A functionally advantageous power transmission and integration of a Falzluftbegrenzers with effect of Aushebelschutzes is achieved by the Ausstellschere pivotally acting with adjustment of the wing from the closed position towards the opening end position Kippöffnungsendlage together with a pivoting Ausstellschere the espagnolette fitting, but moved apart from each other to form a limit stop.

In order to achieve optimum uniform support at a constant transmission ratio between the actuation path, the closed position and opening end position and vice versa, with a linear course of the spring device, the Ausstellschere on a handlebar, which is pivotally mounted with a free end of the faceplate and with the other free End is slidably guided via a pin mounted on the handlebar in a slot of the extension arm, wherein a handlebar having scenery with intervention of a driver attached to the slide follower, the extension arm is positively controlled pivotal and allows a linear thrust movement of the wing-side Ausstellarmdrehgelenks.

In a locked position of the sash to the frame of the window or door, the assembled conventional espagnolette fitting, in operative connection with latching engagements disposed on the frame, is capable of effecting a sealing action by pressure. In order to support a locked effect in the area of the device, to not adversely affect the influence of the sealing effect of the espagnolette fitting with the locking engagements and to effect locking of the deployment arm in the rotational position, the deployment arm of the deployment shears between the articulation on the wing and the Frame, one at the frame facing towards the end open longitudinal section, which cooperates with a fastened to the espagnolette fitting with a drive rod and passed through a slot in the faceplate pin in the closed position of the Ausstellschere.

To achieve a controlled opening of the wing with distances from the frame in the end position of the open position or Kippöffnungsendlage, with a secure stop against unintentional uncoupling of Ausstellschere with an arranged on the frame guide fitting and to facilitate the closing operation from the open position to the closed position, the Extending the Ausstellschere pointing towards the frame pointing by means of a guide pin with the frame attached to the guide fitting in a guide groove of a guide slide leading stored. In addition, preferably, the guide fitting has an inlet and outlet opening for uncoupling for the guide pin from the guide groove, so that the wing without the influence of the device, for example in a tilt-and-turn window or door in tiltable operative connection of the device at a Drehbereitschaftsstellung the espagnolette, can be opened. In an advantageous embodiment, a securing device is further provided, which prevents the self-emergence of the guide pin of the extension arm in a tilt-and-turn window or door in tiltable operative connection from the inlet and outlet opening.

For easy design and connection of the guide fitting during assembly to the frame, the guide fitting has a base plate with mounting holes for mounting screws for attachment to the frame. To prevent leakage of the guide pin from the guide during the movement of the wing to the frame from the closed position into the opening end position, preferably the Kippöffnungsendlage, and to allow entry and exit of the guide pin Ausstellschere the guide fitting, the guide slide in a slot of Base plate slidably guided in the longitudinal direction of the fitting groove and can be forcibly moved to the appropriate position provided.

For easy and safe installation, the safety device is fixed to the base plate non-positively and / or positively. An increase in the reliability of the coupling and uncoupling of the guide pin with the Ausstellschere, for example, in a tilt and turn window or door, in the respective positions of the closed position, the rotation readiness position and Kippöffnungslage the espagnolette is thereby made possible that the securing device with the guide slide in the respective positions by a fixing device is releasably coupled and thus the guide pin during the Kippöffnungsbewegung in the guide groove of the guide slide movably supports. Preferably, the releasable coupling of the fixing device is a latching / snap connection.

In uncoupled position of the Ausstellschere the guide fitting, which is for example in a turn-tilt window or door of the espagnolette in the position for rotary opening and in the locked position, the guide slide and the securing device are spaced transversely to the fitting groove of the wing and form one Gap, which produces the free field of action of the guide pin of the stay of the Ausstellschere. With actuation of the espagnolette in the direction of pivot position or Kippöffnungslage the wing to the frame, the guide pin of the extension is transferred by compulsory displacement of the guide slide in the guide, wherein the securing device with an arm closes the inlet and outlet of the guide slide.

In addition, the invention relates to a method for operating a device for supporting and Facilitating the opening and closing of a wing of a window or a door, wherein between a frame and the wing of the window or the door, a spring means is provided, wherein the spring means is in operative connection with a Ausstellschere. Depending on the direction of movement of the wing to frame in a closed position or in an opening end position, alternately accelerating or damping of the wing achieved, the changing effect of accelerating or damping the wing by an exchange of spring force or energy of the spring device in the closed position and succeeds in the opening end position, which is achieved by the spring means in the direction of the closed position or opening end position, spring force or energy applied to store and dampen the wing and with delivery of the stored spring force or energy from the closed position or opening end position allows acceleration of the wing, wherein the spring force of the spring device is relaxed and re-tensioned in an opening or closing pivoting position.

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.
