Description

The invention relates to an arrangement of an elongate member drive device with at least one elongated, articulated, one-sided curving force transmission element, which with a substantially straight force transmitting portion frictionally between a fixed frame and a rotatable about a first axis of rotation or the like, in particular a window sash, a Flap or a dome light, is arranged, according to the preamble of claim 1.

In one of the utility model DE 298 16 102 U1 known device for moving radially and linearly guided elements, which realizes an arrangement of an elongate member drive device with at least one elongate, articulated, one-sided curvilinear force transmission element, which with a substantially straight, force-transmitting portion frictionally between a fixed frame and a rotatable about a first axis of rotation Wing or the like, in particular a window sash, a flap or a dome light, is arranged, wherein one end of the projecting from an outlet opening in the link drive means straight portion of the force transmission element on the wing or on the fixed frame about a second axis of rotation parallel to the first axis of rotation is rotatably articulated, the link drive means is mounted about a third axis of rotation parallel to the first axis of rotation pivotally mounted on the fixed frame or the wing. The link drive means is arranged on a longitudinal side of the fixed frame or a longitudinal side of the rotatable vane substantially parallel to the longitudinal side of the fixed frame or the transversely to the first axis of rotation and the third axis of rotation is directed transversely to the longitudinal extent of the link drive means. In this case, the link drive means may be housed in an elongated housing and be pivotable together with the housing about the third axis of rotation. This is a compact drive to be created, which can be mounted laterally hinged elements or pivotal elements, with parts of the assembled drive should not protrude into the surrounding space.

The post-published EP 1780362 A1 discloses a motor drive for a pivotable at least about a first axis of rotation of a window or a door with a drive housing in which a tension and compression stiff chain is received, which is displaceable by a motor from the drive housing and which with a free end to a Bearing or a console about a second axis of rotation is pivotally hinged to a frame. The drive housing is mounted on the wing side and pivotable about it about a third axis.

Other known link drive devices are each provided at least for an elongate, articulated, one-sided curvature-capable force transmission element, which allows buckling or deformation only in one direction and enables the transmission of a compressive force on a straight section. For this purpose, the power transmission element members have, which are formed and arranged so that they lie in straight aligned link chain and under the influence of the compressive force to each other from a drive element, such as a motor, on an object to be actuated by this, for example, a window or a flap to pivot transferred to ( EP 0 975 897 B1 ).

In order to meet the requirements placed on the articulated force transmission elements, they can be designed in many ways. In particular, they may consist of sections of an extruded profile and be formed on an engagement side for the sprockets with a joint socket and a joint cylinder, whereas they have at right angles thereto plane support surfaces on which they can support each other along a substantially straight line to the compressive force transfer. Such power transmission elements can be easily produced for small series.

Alternatively, the means for imparting compressive force to the object to be actuated may comprise two toothed belts as articulated force transmitting elements which in a zipper-like manner mesh along a substantially straight distance to transmit the compressive force to the element to be actuated along this straight path. The timing belt allow a deflection of the power transmission elements outside the straight line in a quiet and low-wear manner. The timing belt are also low production, since they have no large number of parts to be assembled.

A typical link drive device for two articulated power transmission elements comprises two driven sprockets, each of which engages one of the power transmission elements, by 90 ° to divert at a separation point at which the two power transmission elements are either brought together depending on the drive direction of the two sprockets, so that they interlock, or the merged power transmission elements are separated. Furthermore, the merged power transmission elements are pushed out of an outlet opening of the link drive device to the outside, where they can transmit forces, in particular a compressive force, to the element to be actuated. On the other hand, separate, deflected, relaxed sections of the power transmission elements are guided on both sides of the separation point in a left and in a right guide region of the link drive device at the separation point within the link drive means, in which they can be further deflected and stored compact. Each of the guide regions extends laterally from the separation or exit opening, resulting in the typically elongated shape of the limb drive device, which is normally located in a correspondingly shaped housing with the outlet opening ( EP 0 534 413 B1 ).

The arrangement of a link drive device with at least one articulated force transmission element can serve as an actuating device for opening and closing a window, a door, a ventilation flap or the like and should be characterized for this purpose by high operating force, large Ausstellweite and compact design ( EP 0 534 413 B1 ). Accordingly, such an arrangement is known as an actuating device for opening and closing a wing pivotally connected to a fixed frame about a pivot axis in which the link drive means is pivotally mounted to the wing or frame about a pivot axis. In this case, the pivot axis is oriented parallel to the pivot axis. Two driven with the drive device chains as power transmission elements, the form a force transmission member are hinged at an attachment point to the frame or the wing about a hinge axis, which is also parallel to the pivot axis. This is to be achieved inter alia that the power transmission member and the drive device are always on a straight line, so that therefore bending moments are kept away from the power transmission member. This known actuator corresponds to the generic arrangement of the present application, in which the first axis of rotation is the known pivot axis, the second axis of rotation is the known hinge axis at the attachment point of the chains and the third axis of rotation is the pivot axis of the drive device.

In particular, in the known actuator, the drive device is located remotely from the pivot of the blade on the fixed frame, with the elongated housing of the drive device being parallel to the pivot axis of the blade. The attachment point of the chains is located on the wing at a remote from the pivot axis of the wing body, with the result that for a certain opening angle of the wing of the substantially straight portion in which the two chains are brought together, must be relatively long and so that the chain lengths to be stored in the closed state of the wing in the drive device or the housing. The aspired with this actuator goals of large Ausstellweite and the compact design are thus achieved only imperfectly. Furthermore, with increasing free length of the straight portion of the power transmission element increases its tendency to laterally deflect or bend when transmitting a compressive force. As a result, the forces that the straight portion of the power transmission element can transmit are limited.

The prior art further includes an actuator for a window, a French window, a ventilation flap or the like, in which a wing is pivotable relative to a frame. For this purpose, a drive or a link drive device of two chains, which are connected to each other in the extended state and are referred to as a force transmission member attached to the frame ( EP 1 422 374 A2 ). A free end of the power transmission member is hinged to the pivotable wing by means of a bearing block gimbal rotatably. The link drive device is arranged approximately centrally on a longitudinal side of the frame and, accordingly, the free end of the force transmission member approximately centrally on a longitudinal side of the wing to be actuated. In order to achieve a large range of the wing with a small footprint for the chains, these are specially designed so that they form an arc in coupled condition. The arc of the chains is generated in that one of the chains in the extended state has a shorter distance from bearing pin of chain links to each other than the other chain. The chain with the shorter center distances is to be arranged closer to the bearing of the wing on the frame than the chain with the longer center distances. The formation of the two chains in different ways increases the production cost. In addition, the chain design is limited in view of typical requirements to be met by the power transmission element.

In another known arrangement of a so-called drawbridge solution, an elongate member drive means is also fixedly secured to a longitudinal side of a frame parallel thereto and a straight portion of a chain exiting the link drive means is hinged to a wing of a tilting window, the pivot axis thereof Horizontal axis of rotation runs horizontally (publication by STG-BEIKIRCH Industrieelektronik + Sicherheitstechnik GmbH & Co. KG "The EM chain drive as drawbridge solution"). An exit opening of the chain is located on the link drive means remote from the first axis of rotation in the uppermost region of the frame. The attachment point of the free end of the chain is located at a corresponding distance from the first axis of rotation on the pivotable wing. In order to achieve the desired extremely large wing opening in tilt windows, thus a large stroke or a long straight section of the chain is provided, resulting in a correspondingly large longitudinal extent of the link drive means results in which is not to be stored from the link drive device emerging part of the chain , Thus, the straight, force transmitting portion of the power transmission element or the chain can adjust, the chain must be guided in the link drive means so that they can emerge at different angles to an outlet opening of the force transmission element from this or a housing of the power transmission element. If the straight section of the chain is subjected to pressure, the chain should be particularly avoided due to the length of the section, which limits the modifiability of this arrangement.

With the arrangement of the type mentioned above, a compact, uncomplicated arrangement of an elongate member drive device is to be created, with a large opening angle of a rotatable blade or the like with a small stroke of the link drive device is achieved. The arrangement should be distinguished by low production costs. It should be installable concealed in order to be architecturally appealing, for example, integrated into a facade roof construction. It should not be a special construction require the elongated, articulated, unilaterally curvilinear force transmission element, which can thus be optimized to meet other requirements.

With this arrangement, it is achieved that the link drive means close to the first axis of rotation about which the rotatable vane or the like can be rotated, on the fixed frame or in kinematic inversion instead can be arranged on the rotatable wing. In this case, the attachment to a longitudinal side of the fixed frame or a longitudinal side of the wing, so that the elongated member drive means extends substantially parallel to the longitudinal side of the fixed frame or the wing and transversely to the first axis of rotation. A free end of the force transmitting element emerging from the link drive device, or more precisely its straight, force transmitting section, is mounted on the fixed frame so as to be pivotable about a second axis of rotation parallel to the first axis of rotation on the rotatable wing or in kinematic reversal. The third axis of rotation about which the link drive means is rotatable extends transversely to the longitudinal extension of the link drive means or their housing. This ensures that the link drive device synchronously rotates during its stroke movement in the vicinity of the first axis of rotation of the wing, so that the straight line section always exits at a predetermined angle of preferably 90 ° to the stroke direction of the link drive means from the outlet opening. In particular, for this purpose, the third axis of rotation about which the link drive device is rotatable, arranged in the vicinity of the outlet opening of the straight, force-transmitting portion of the force transmission element or in the extension behind the outlet opening be. Thus, a hinge assembly is provided in which over the straight, force transmitting portion of the power transmission element, in the longitudinal direction of large forces between the link drive means and the rotatable wing or the fixed frame can be transmitted, with a transverse load of this straight portion is minimized, the Power transmission element in this section would unwanted kinking would try.

The elongated, articulated, unilaterally curvilinear force transmission elements used, in particular a chain or a toothed belt or two chains or timing belts, which are combined to form the straight, force-transmitting portion must be backsplash when extending out of the link drive means in the straight, force transmitting portion and remain stable in the thrust direction, because otherwise the required pivotal movement of the straight portion and the related limb drive device is not possible without impairment or buckling.

The link drive device or its housing can additionally be rotatable about a further axis, which runs in the longitudinal direction of the stationary frame or of the rotatable wing, so that the link drive device is mounted, as it were, gimbal-like. Also, the attachment of the free end of the straight, force transmitting portion of the power transmission member to the rotatable wing or the frame can be made with additional pivoting about a further axis which is transverse to the first axis of rotation of the rotary wing.

The arrangement can in many ways for opening and closing a window sash to the outside or inwards, a flap, be used in particular in a smoke-heat extraction system (RWA system) or a dome light. With the arrangement can be very large erection of 165 °, for example, as they are required for alarm positions in RWA systems.

The member drive means housed in a usual way in an elongate housing are simply mounted together with the housing about the third axis of rotation pivotably on the longitudinal side of the fixed frame or of the rotatable sash.

The present invention has for its object to arrange a limb drive device of compact size, especially in the longitudinal extent of the limb drive device, architecturally appealing concealed.

For this purpose, the link drive device according to the invention is housed within a longitudinal spar of a sash or the fixed frame, so that protrudes substantially only the straight section of the power transmission element of the longitudinal spar.

In order to achieve sufficient pivotability of the link drive device in the longitudinal spar even when the substantially closed longitudinal spar has a relatively small clear cross-sectional area, has a longitudinal spar wall at the outlet opening of the limb drive means on a first open portion and an opposite rear wall has a second open portion on. One end of the pivoted link drive device can pass through these open sections when the wing is opened. When the wing is closed, however, the link drive device is almost completely in the longitudinal spar. The link drive device is therefore not visible from the outside, at least in the closed state of the wing.

In addition to the concealed placement of the link drive means within the longitudinal spar of the fixed frame or the sash can according to claim 2 in the profile to which the longitudinal beam belongs, an electrical power supply and / or control electronics of the link drive means be concealed. In an advantageous way In this case, lines which connect a drive motor of the link drive device, the power supply and the control electronics are not deformed by movement of the sash.

Particularly advantageous is the compact overall arrangement of the link drive device defined in claim 3, characterized in that the second, parallel to the first axis of rotation of the wing axis of rotation at which a free end of the straight force transmitting portion of the force transmission element is articulated to the wing or the fixed frame , Is arranged from the first axis of rotation less than half the extent of the wing away from the axis of rotation. From the thus achieved short stroke of the power transmission element results in a short opening time. In particular, within an opening time prescribed by legal provisions, an opening of a flap in a SHE system can be carried out over a large, aerodynamically effective opening angle, which makes the production of special strokes largely unnecessary. Although the opening angle to be achieved within the required opening time presupposes a considerable opening force in this case, it is realizable and acts on it as a result of the alignment of the force transmission element achieved with the rotary joint arrangement comprising the first axis of rotation, the second axis of rotation and the third axis of rotation that she the opening force does not lead to a kinking of the power transmission element.

As mentioned above, the arrangement can be realized with optimized for further aspects power transmission elements.

According to claim 4, two toothed belts may be provided as force transmission elements, which are suitable to mesh along the rectilinear portion or a straight Stecke zipper. The toothed belt provided as a force transmission elements allow the transmission of the pressure force on the straight Stecke in a quiet and low-wear manner.

In another embodiment according to claim 5, the transmission element may consist of sections of an extruded profile, which are formed on an engagement side with a joint socket and a joint cylinder and at right angles thereto have plane support surfaces on which they can support each other. The sections are sawn low production from an extruded profile, in particular an aluminum extruded profile. In the longitudinal direction of the extruded profile with a substantially rectangular cross section, the support surfaces of the sections are preformed on two outer sides facing away from each other, so that the size of the support surfaces of the separated or sawn sections simply results from the longitudinal distances between the separation points of the extruded profile. In this way, the size of the support surfaces can be flexibly and economically adjusted without additional tools to the forces to be transmitted via the support surfaces.

A link drive means, generally designated 1, comprises two elongated, articulated, one-way, curvilinear force transmitting members, the visible straight portion of which is indicated at 2. Apart from the straight portion 2, the link drive means is housed substantially in a housing 3. The link drive means has in the housing two electric motor driven sprockets or rollers, not shown, each of which engages in one of the two power transmission elements to merge both to the straight section 2 at a separation point in the housing 3, to redirect 90 ° and to store in the housing or the limb drive device.

In the Figures 1 and 2 is the link drive device with the housing 3 laterally attached externally to a fixed window frame 4 and is connected via the common straight portion 2 of the power transmission elements with a window sash 5 in combination, which pivoted by means of bearings or hinges about a first axis of rotation 6, ie tilted outwards can. For this purpose, the link drive device 1 is suitable, by means of which straight portion 2 of the force transmission elements exert a tensile force or a compressive force on the window sash 5 to the window to close or open. The link drive device not only causes the corresponding adjustment of the window sash, but also keeps it in the position set by the control of the link drive device.

In order to transmit a large tensile force or compressive force on the window sash 5, the link drive means is arranged in the vicinity of the first axis of rotation of the sash, at a distance less than half the longitudinal extent of the sash offset by 90 ° to the first axis of rotation. This allows a short stroke of the link drive device for a given opening angle. Accordingly, large forces must be transmitted from the link drive device on the window sash 5. So that this takes place as reliably as possible without loading of the power transmission elements transversely to the straight section, one end of the straight section 2 is rotatably hinged to the window sash, wherein the fictitious extension in the drawing second rotary axis is denoted by 7. Also, the member drive device 1 with the housing 3 is rotatably supported, namely about a third axis of rotation, which is also shown fictitiously extended in the drawing and is denoted by 8. Out FIG. 2 It can be seen in which position the third axis of rotation 8 behind the housing 3 in extension of the straight portion 2 of the force transmission elements, which emerge from an outlet opening 9 from the housing is arranged.

By virtue of the rotary joint arrangement constituted by the three axes of rotation 6, 7, 8, it is achieved that virtually no bending moments are exerted on the straight section 2 of the force transmission elements upon actuation of the link mechanism and tilting of the sash 5, which could lead to a bending of the straight section 2. Rather, the Link drive device 1 synchronously to the tilting movement of the window sash 5 only rotated so that the straight portion 2 of the power transmission elements always emerges substantially at right angles from the outlet opening 9 of the housing 3, whereby an optimal power transmission is achieved. The third axis of rotation 8, about which the link drive device 1 is pivotable on the window frame 4, is offset by 90 ° to the longitudinal extent of the housing 3 of the link drive device, so that arranged in the vicinity of the first axis of rotation 6 link drive means approximately parallel to a longitudinal spar 10 of Window frame or its profile is oriented and protrudes little over the profile when the sash 5 is tilted.

In the embodiment according to the FIGS. 3 to 5 is the link drive device, in particular the housing 3, housed inconspicuous in the profile of the window frame 11, so that essentially only the straight portion 2 of the force transmission elements protrudes from the profile, which in turn is pivotally mounted about the second axis of rotation 7 on the window sash 5.

Thus, even with a small cross section of the profile, the housing 3 of the link drive means does not abut against a front wall of the longitudinal spar 10, when the housing 3 is tilted according to the tilt position of the window sash 5, the longitudinal spar wall at the outlet opening 9 of the link drive device 1, a first open section. 1 2 and a corresponding second open section 13 is arranged opposite the open section 12 in the rear longitudinal spar wall, see FIG. 5 , Sections of the housing 3 of the link drive device can protrude in the open tilt position of the window sash from the profile of the window frame 11 and the housing 3 can also be set here automatically, that the straight portion 2 emerges at a constant angle from the outlet opening 9 of the housing 3 and the power transmission between the link drive device 1 and window sash 5 is optimized.

With regard to the positioning of the third axis of rotation about which the link drive device 1 is rotatable, it is specified that this third axis of rotation 8 is preferably positioned in extension of the straight section 2 on the side of the housing 3 opposite the outlet opening 9, transversely to the longitudinal extension of the housing 3, as from the FIGS. 2 to 4 seen. Thus, the straight alignment of the section 2 with constant exit angle from the housing in a wide range is achieved regardless of the tilted position of the sash 5.

In the embodiment according to the FIGS. 6 to 10 a box-shaped frame 14 is fixed in a non-designated roof substantially horizontally. It is a building fixed frame, which carries a rotatable frame 15 of a flap, not shown, or a dome light, wherein the frame is rotatable about a fictitious extension shown first axis of rotation 16 on the fixed frame.

For pivoting the rotatable frame 1 5 is a link drive means 1 'with a straight portion 2 of the power transmission elements, the free end of the rotatable frame 15, which thus has the function of a wing, is pivotable about a second axis of rotation 17, whose fictitious extensions in FIG. 6 are shown and which runs parallel to the first axis of rotation 16. The link drive device 1 'is mounted inside on a longitudinal side 21 of the fixed box-shaped frame 14. The storage of the link drive device 1 'is used turn a third axis of rotation 18, whose fictitious extension in FIG. 6 is shown and which is placed at a position which is in extension of the straight section 2 of the power transmission elements in the closed state of the rotatable frame 15 under the link drive means. The third axis of rotation 18 in this case again runs transversely to the longitudinal extension of the elongated housing 3 and is arranged in the vicinity of the first axis of rotation 1 6.

How out FIG. 7 can be seen in the open position of the rotatable frame 15, only a small part of the housing 3 via the fixed box-shaped frame 14 via when the link drive means 1 has adjusted according to the open position of the rotatable frame 15. In the closed position of the rotatable frame 1 5, the housing 3 and the power transmission elements are covered to the outside by the rotatable frame 1 5 and they can also be covered inwardly with respect to a central opening 19 by an additional partition which inside in the fixed frame 14 in Distance to the longitudinal side 21 is arranged.

With basically the same arrangement in the FIGS. 6 and 7 is shown, but also a particularly large opening angle can be realized with the relatively short straight portion 20 of the power transmission elements, as in the FIGS. 8 to 10 shown. Even in the up to about 165 ° wide open position of the rotatable frame 15 leaves the straight portion 20 of the force transmission elements, the link drive device 1 'substantially perpendicular to this at the outlet opening, in the FIGS. 8 to 10 not designated. It is therefore advantageously not required for a particularly large opening angle custom-made.
