Definitions

• the invention relates to a window or a door, in particular for a building, with at least one wing which is pivotally arranged on a frame and with a drive device for automatically moving the wing relative to the frame and a drive device according to the preamble of the claim
• DE 41 31 762 shows a drive for a wing of a door or a ventilation flap or the like, in which a drive housing is arranged on the wing to be tilted in the upper horizontal spar. At least one chain is led out of the drive housing, which is designed in such a way that it forms a pressure-stable element which opens the sash when moving out of the drive housing. Closing is done by retracting the chain.
• Another problem is that e.g. When opening the sash, a decoupling of the chain on the frame and / or sash frame is necessary, which may be difficult to implement and handle mechanically.
• DE 19949 940 AI and DE 19949 941 AI relate to motor-driven opening devices for rotatable and tiltable windows, in which the drive device is placed on the windows.
• the drive device engages by means of a driver in a slide of the frame fold on the sash frame, which is controlled by is provided ore pins which engage in a control curve of the handlebar of the opening device.
• the control pin is guided along the control curve (link) via the linear displacement of the slide and thus causes a corresponding opening movement of the window sash in the upper horizontal area.
• control curve is to be provided very close to the wing-side pivot point of the scissor arm and that this results in an unfavorable leverage ratio for the opening movement and in particular the required closing surfaces. the increased effort required.
• the invention aims to largely solve the above problems.
• the invention achieves this object with regard to the window or the door by the subject matter of claim 1 and with regard to the drive device by the subject matter of claim 27.
• the drive device has a power and energy store, which is designed and arranged to open the wing.
• the power and energy storage device can be designed to be particularly compact and space-saving and can be accommodated on the window, in particular on the sash, and offers high operational and functional reliability as well as high movement accuracy with little wear.
• the invention is particularly suitable for tilt-and-turn or tilting or hinged windows or doors and for opening the sash in a ventilation position.
• the power and energy store is particularly advantageously used exclusively for opening the window or the door and the closing of the window or the door is realized with the aid of a flexible pulling device, in particular a motor-operated cable pull.
• a flexible pulling device in particular a motor-operated cable pull.
• the power and energy storage device as well as the pulling device can be designed to be particularly small and compact. It is also possible to arrange the cable pull and the energy and energy storage separately at (almost) any location and thus to make optimal use of the available space to accommodate these components.
• the flexible pulling device not only closes the window but also recharges the power and energy storage or moves it back into its energy storage position.
• the energy store for the sole purpose or to support the closing of the window or door, although the variant of the use for opening is preferred.
• the beneficial effect can be used that only a small amount of force is usually required to tilt a window or door.
• gravity or the sash weight possibly reinforced by a certain spring force of the seals between the frame and sash, can have a supporting effect when moving to the tilt position.
• the spring should support the opening movement until the maximum tilt position has been reached and also hold the window in the opening position, for example also to prevent it from being moved by air currents or even being hit or closed by wind suction.
• the power and energy storage can be easily realized as a spring.
• Springs are generally very compact, maintenance free and inexpensive. It is particularly advantageous if the spring is a spiral or a leaf spring. Alternatively, the spring can also be a spiral spring. Other compression springs, in particular gas compression springs, are also conceivable.
• the drive device comprises the flexible traction device already mentioned, in particular in the manner of a cable pull with a cable. Since the window or door is opened in another way, in particular by an energy and energy store, the use of a rigid chain to open the window is no longer necessary. Rather, a flexible pulling device is surprisingly sufficient for closing, in particular the particularly inexpensive and compactly implementable cable pull.
• the traction device can also be used or act directly as an opening limiter.
• the drive device preferably has an electromotive drive for actuating the pulling device.
• the electromotive drive can act directly on the power and energy storage device in order to move it back into its energy storage position after loosening.
• the cable of the cable can be round or band-like.
• An opening device is preferably arranged between the wing and the frame, which in turn can be designed in a simple manner as opening scissors, which preferably has a main scissor link and an additional scissor link, in particular in such a way that the main scissor link can be pivoted with one end on the frame and with its other end is pivotably and slidably arranged on the casement in a scissor housing.
• the energy and energy stores can act directly on the opening device, which is particularly simple and compact in terms of construction or, for example, on the frame or on an axis of rotation between the frame and sash. Depending on the arrangement, a larger or smaller stroke is required and the lever and force ratios change, which requires appropriate dimensioning of the components.
• the force and energy storage can act directly on one of the scissor links of the stay scissors, which makes the invention particularly easy to implement and assemble, especially when the force and energy store is designed as a spring, which is between the sash or frame and the stay scissors is arranged.
• the spring can be arranged between the main scissor link and the additional scissor link.
• the spring is preferably a spiral spring, which is supported on the wing and on the axis of rotation of the additional scissor link.
• the traction device acts between a handlebar of the opening device and the wing.
• the flexible traction device is attached at one end to one of the scissor links, in particular to the main scissor link, and with its other end to a winding spool on the wing, which can be rotated by the electromotive drive.
• the drive device is preferably designed as a preassembled unit and is preferably arranged on the sash, so that the drive device is no longer necessary when the window is installed. If the drive device acts on the fitting (i.e. the opening device or a hinge), it is even possible to install a window or door, which does not differ from that of a window or door without a drive device or does not require any additional work steps.
• the traction device is advantageously fastened in half of the main scissor link, which lies towards the hinged area of the scissor link on the frame, in particular in the last third of the main scissor link towards the frame.

• a tilting window usually has its axis of rotation X “below”, whereas a hinged window has “above”. In this case, the arrangement in FIG. 1 would have to be adapted accordingly.
• a tilt and turn window enables opening about two alternative axes, usually about a lower “X” and about a rotation axis “Y” on one side.
• the tilt and turn window has a frame 2 and a sash 1, the sash 1 being pivotally mounted on the frame 2 on at least one or two of its sides according to FIG. 1.
• the wing 1 has a wing frame 35 and can be provided with a disc.
• an opening device On its side opposite the pivot axis, an opening device is arranged between the sash and the frame, which in the manner of an opening setting scissors 3 is formed.
• the opening scissors 3 have a main scissor link 4, one end of which is rotatably attached to the frame 2 - here in the upper corner region of the frame - and the other end of which is rotatable and displaceably guided in a link 30 of a rod-like scissor housing 6, which in turn is on the upper side of wing 1 is fixed.
• one end of an additional scissor link 5 is articulated to the main scissor link 4, the other end of which is in turn rotatably - but non-displaceably - articulated on the scissor housing 6.
• the pin-like axis of rotation 13 of the additional scissor link 5 on the wing 1 passes through the scissor housing 6.
• the one end of the additional scissor link 5 is fixed at about one point of the main scissor link 4, which here is exemplary - but favorable in terms of leverage - to about 1/3 the length of the main scissor link between the sash 1 and the frame 2 ,
• FIG. 2 shows an individual illustration of the opening device from FIG. 1 in the closed position, which corresponds to the closed position of the tilt and turn window.
• a drive housing 7 On the lower side of the scissors housing 6 in the installed position, a drive housing 7 is arranged, which serves to accommodate an electric motor, not shown here, possibly together with a gear.
• the drive housing 7 can thus be fixed together with the scissors housing 6 by means of common fastening elements on the wing 1, for example by latching, screwing and / or engaging in a chamber or an open side wall of the actual wing frame 35 (in FIG. 2 not recognizable).
• the drive housing 7 passes through a wall recess in the casement 35 and is otherwise largely or completely covered by the scissor housing 6.
• a push rod 8 of the opening device is fixed and guided on the rod-like scissor housing 6.
• One end of the push rod 8 is connected to a fitting push rod 9 of an otherwise not shown locking fitting.
• the push rod 8 provided with a plurality of recesses - which remains on the sash when the tilting window is opened - is guided up to the area of the articulation of the main scissor link 4 on the frame 2, which is attached to a band-like or hinge-like swivel joint 31 on Frame 2 is articulated.
• the push rod 8 includes the scissors housing 6 in a frame-like manner and extends up to a bolt 10, in which a locking bolt 11 of the main scissor link can engage, which is positioned close to the articulation area of the main scissor link 4 to the frame.
• FIG. 2 shows the opening device 3 in its open position, which corresponds to the open position of the tilt and turn window.
• the main scissor link 4 has been pivoted out in this position via the additional scissor link 5, a pin 32 being displaced in the link 30 of the scissor housing 6 - here it has been withdrawn.
• the backdrop 30 limits the movement of the main scissor link 4 and thus the opening angle of the tilt and turn window.
• the drive device 40 which is accommodated here in a particularly compact and space-saving manner on the casement, serves to open and close the window 1.
• the drive device 40 has, on the one hand, a force and energy store 12 for opening the tilt and turn window and, on the other hand, a flexible pulling device for closing.
• springs are suitable as the force and energy store 12, and in FIGS. 2 and 3 a spiral spring 33 was selected as the force and energy store because of its low cost and its compact geometry.
• the one end supported on a pin 34 of the scissor housing 6 spiral spring 33 acts according to FIG. 5 with its inner end directly on the axis of rotation 13 of the additional scissor link 5, which is secured against rotation and thus causes a rotation of the Axis of rotation 13 and thus opening the stay scissors 3.
• the opening of the window is therefore achieved in the simplest way without the supply of external energy or the use of a motor solely by the force and energy store 12, possibly supported by gravity. It is advisable to additionally provide the drive device 40 with an electromotive drive which effects the closing of the window and thus also a tensioning of the spring or the storage of force and energy in the force and energy store 12.

• the pin 34 of FIG. 5 also serves as a bearing pin for the deflection roller 15 on the opposite side of the scissor housing 6.
• a particular advantage of the arrangement is that the train is positioned independently of the power and energy storage 12 and can be accommodated in a space-saving and power-optimizing manner. An arrangement separate from the opening device would even be conceivable if there is insufficient space available in its area.
• Fig. 3 The arrangement shown in Fig. 3 is particularly light, compact and space-saving and surprisingly enables the accommodation of virtually all functionally essential elements as a pre-assembled unit directly on the wing 1 (in particular on and in Casement 35). Only the main scissor link 4 still has to be articulated on the frame 2.
• Fig. 7 shows an alternative embodiment of a drive device 40, wherein a winding spool 19 is provided on the drive housing 7, which receives two cables 14, 14 ', which are wound in opposite directions on the winding spool 19.
• Two pulling devices can be used in this way, e.g. on tilting or hinged casement windows (otherwise not shown).
• Fig. 8 shows a pure tilt window, which is indicated by the axis of rotation 20.

• a spiral spring 38 in a V-shape is arranged directly between an extension arm 21 and a basic fitting body 22, which in turn could be the main scissor link and a wing part such as the scissor housing.
• FIG. 11 illustrates the compact arrangement of the scissor housing 6 and main scissor link 4 elements on the sash frame and the likewise particularly space-saving arrangement of the drive housing 7 in a chamber 39 of the sash frame 32 on the basis of a section through the sash frame 35 and the frame 2.
