Description

The The invention relates to an actuating device to open and closing a grand piano a window, a door, a ventilation flap or the like, according to the preamble of claim 1.

The The invention is based on the use of linear drives, which in different versions are known, in particular with pressure air cylinder or hydraulic cylinder as a drive source or with an electric motor drive. One linear transmission element the linear drive can simply push a push rod of the compressed air or hydraulic cylinder or in the case of an electromotive linear drive to be a rack. But it is also possible, a linear force transmission element with a Zugseilanordnung for to realize two opposite directions of pull.

An actuating device according to the preamble of claim 1 is known, for example, for a wing, which is mounted on at least one side pivotally mounted on a window frame, wherein the wing has a sash ( DE 103 00 653 A1 ). Between the wing and the frame an opening device is arranged on one side, which lies opposite a pivot axis of the wing. The opening device has a main scissor arm, whose one end is rotatably fixed to the frame and the other end is rotatably and ver pushed out in a backdrop of a rod-like scissors housing, which is fixed to an upper side of the wing. The Ausstellschere controls the movement of the wing when opening and closing a tilt and turn window to which the wing belongs, as well as a clear positioning of the wing with respect to the frame in the closed position. To open the window in the tilted position and to close the window is a compact on the wing and space-saving accommodated drive device, which has a thrust-rigid drive chain as the drive member, which is fixed substantially at the center of the main scissor arm at a pivot point. From the main scissors link, the drive chain extends perpendicular to the sash and is deflected at this 90 ° and guided to a drive housing, which includes the drive source, in particular an electric motor with gear. The relatively complicated, rigid drive chain can be at least partially replaced in a variant by a lower-cost push rod, in particular a rack, or reduced to the minimum required to ensure the function of opening the window effective length. To drive the push rod different mechanisms are possible, such as a drive by a drive gear or a spindle or other thrust-generating motor drive mechanism. However, there remains a functionally necessary portion of the complex thrust-resistant drive chain. In addition, in this drive device, the relatively small opening angle of the window in the ventilation position, or tilt angle, of less than 45 ° in applications disturbing in which a larger opening angle is required.

Consequently can a chain drive arranged with deflected push link chain so be that this is not in the space between profile elements of the wing disturbing protrudes. However, due to reasons of stability, he loses a sufficient compressive force to open of the grand piano with increasing stroke length stronger than for drives with a rigid lifting element such as a push rod.

In order to create an actuating device or a drive for opening and closing a wing, or a flap element, wherein the linear drive laterally concealed on the flap element is mounted and this can operate with constant pressure or tensile force, it is known a Schubgliederkette about the axis of To redirect the sprocket and to connect the loose end of the chain with the flap element ( DE 298 16 102 U1 ). The chain is guided so that it always assumes a stiff position in the extended state. This can be achieved by an additional lever element generating a moment which, together with the force acting on the guide of the chain, results in the desired force sum. The sum of forces can be generated by various means, for example with a resilient element, which is connected via a guided plunger with the leadership of the chain. A compact drive can be provided by a lever is fixedly mounted on the drive unit, which rests on a pressure roller on the hinged element to actuate this. The hinged element may instead also be connected via a guide and connecting element fixed to the drive. - With all embodiments, it is desirable to operate the flap element with constant pressure and tensile force. However, since, for example, large resistances in the opening of the flap element are to be overcome by snow load and / or freezing, the operating speed over the entire opening path for a given drive power can be undesirably slow.

Around To remedy this, additional measures are known from practice, such as in the form of a to the flap element or the wing with Pressed a gas spring Roll to open, whereas closing a complicated rope construction is provided.

Of the The present invention is therefore based on the object, while avoiding the disadvantages of the known actuators to provide such a type of the aforementioned type, the linear drive concealed in the frame profile can be integrated and with the a large opening angle in Relation to the stroke of the linear drive can be achieved quickly can. The pressure force to open and traction to close the wing dependent on from its opening angle be structurally simple adjustable, in particular so that for reliable opening of the wing a big Pressure on the wing exercised becomes.

These Task is by an actuator solved, having the features specified in claim 1.

To the Installation in a substantially horizontal frame profile has the actuator specified in claim 2 feature that the linear transmission element or according to claim 7 prefers the push rod to its or its drive source opposite end by the guide element rotatable in the second setting and in the third setting and slidably guided is.

When Variant for a substantially vertical frame profile, as is the case for a window is provided, is particularly suitable an actuator according to claim 18th

In two variants of the actuator let yourself compactly integrate them into the frame profile, according to the claim 3 in a lateral space of the closed frame profile, so that she is hidden in it. There is a longitudinal axis of the linear drive with the push rod substantially parallel to a main plane of the frame profile in the closed state. As the main level, the level can be seen, in which the main opening of the first profile element, namely of the stick profile, lies, which by the wing on the second profile element, namely the sash profile is closed.

A essential feature of the actuator according to the invention consists in that by the design of the elongated second backdrop and / or third backdrop, in particular by the slope, d. H. Tilt to the respective direction of movement of the linear force transmission element or preferably the push rod of the linear drive according to claim 10 "the gear ratio between a lifting movement of the push rod of the linear drive and an opening angle change of the frame profile can be predetermined, even in sections different along the stroke. The direction of movement of the push rod is determined by the third scenery, and exclusively by this determines when the third backdrop in a fixed profile element is arranged.

Especially For example, it is advantageous for substantially horizontal installation possible, the Stroke movement of the linear drive initially very slowly translate for a high torque on the movable profile element, d. H. airfoil of the frame profile. This allows the sash profile according to legal Provisions are reliably opened even under snow load and / or icing.

to Realization of the above mentioned huge Torque runs according to claim 4 a first section of the second backdrop with a lesser slope in terms of the third backdrop as a second adjacent to the first section Section of the second gate, with the guide element in the closed Condition of the frame profile in the first section of the second backdrop and intervene in the third backdrop.

space saving can according to claim 5 the first section of the second backdrop and the third backdrop in the closed state of the frame profile approximately in the direction of movement the linear transmission element the linear drive and substantially parallel to the main plane of the closed frame profile run.

To the space-saving arrangement belongs to Claim 6, that also the first backdrop essentially parallel to the main plane of the closed frame profile.

For the others Lifting movement when the sash profile for example, an opening angle of 45 ° opposite the Can cross horizontal the above-mentioned gear ratio appropriate in fast changed be to the wing end position reach quickly. It is enough a relatively small one Torque applied to the movable profile element. For this purpose is the carriage in the second mentioned in claim 4 Section of the second scenery led, whose slope is greater than that of the first section is.

The Sectional inclinations of sections, in particular the second Backdrop and / or possibly the third backdrop can according to claim 11 continuously merge, for which at least one of the sections is curved at a transition point. With that you can a constant change of the translation and achieved a smooth movement of the moving profile element become.

constructive can the guide element, which z. In the embodiment the actuator according to claim 2, the linear power transmission element over, in particular the push rod facing away from the drive source end in the second backdrop and in the third backdrop rotatable and movable leads, according to claim 8, a friction at this end of the linear force transmission element mounted leadership role be, which intervenes in the second backdrop and in the third backdrop.

Basically suitable is a bolt as a guide element.

Especially good is the clear height used the frame profile when the guide element according to claim 9 a carriage with three guide rollers of which two intervene in the second or third scenery and the third leading role engages in the other backdrop. As a result of the two leadership roles, which intervene in the same scenery, the carriage can not undesirable but must follow the course of the scenery into which the two guide rollers intervention.

Farther can constructively appropriate according to claim 12 at least one of the above first backdrop, second backdrop and third gate each formed as a groove in a plate-shaped bracket be, which is attached to one of the two profile elements.

material saving it is according to claim 13 possible, at least one of the three scenes each as a groove from one of the form both profile elements themselves or the handlebar.

It Depending on the construction and training of the frame profile are diverse Configurations of the actuator possible: According to claim 14, the linear drive is mounted on the sash profile and the third backdrop is set on the floor profile.

According to claim 15, however, the linear drive is mounted on the pole profile, at which also the third backdrop is set.

According to claim 16, the linear drive is mounted on the pole profile and the third Backdrop is on the sash profile established.

According to claim 17, however, the linear drive is mounted on the sash profile on which also the third scenery is fixed.

As mentioned above is for essentially vertical installation of the frame profile, the execution of actuator provided with the features of claim 18, according to which the guide element an auxiliary push rod is articulated by the guide element rotatable in the second setting and in the third setting and slidably guided is, being to the the guide element opposite end of the auxiliary push rod facing away from the drive source End of the linear transmission element, in particular the push rod is articulated and wherein the the guide element opposite end of the auxiliary push rod and the drive source opposite end of the linear force transmission element or the Push rod in an auxiliary link in one of the two profile elements guided rotatable and movable are. This ensures that the actuator in the open Position of the grand piano a bigger torque gives to this. The safe closing of the wing can also by the Design of the second and the third scenery can be achieved. there the third gate can be made relatively short.

In The figures of the drawing are consistent Elements provided with the same reference numerals.

The subsequent embodiments be first in view of its half-open state described, since in them the individual elements partly clearer are recognizable as in the closed state.

Accordingly, in the 1 to 20 With 1 a stick profile and with 2 designates a wing profile, which together form a frame profile of a wing on which an actuator with a linear drive 3 is arranged to move the wing from a closed position according to the 4 and 5 in a half-open position according to the 1 and 2 or beyond in a further open position according to 3 to swing and, if necessary, reverse swing back.

It should be noted at this point that the first to fifth embodiments according to the 1 to 24 are provided for a horizontal installation of the frame profile and the sixth embodiment according to the 25 to 27 for a vertical installation of the frame profile.

More specifically, in the first embodiment, the actuator is the linear actuator 3 around a pivot axis 4 swiveling, attached to the sash profile 2 is mounted. The sash profile is about its pivot axis 2a pivotable. A push rod 5 protrudes from an unnamed drive source of the linear drive 3 out, which is realized in the present embodiments as a pneumatic cylinder.

At one of the drive source remote from the end of the linear drive 3 is the push rod 5 with a leadership role 6 provided, which constitutes a guide element with which said end of the push rod in a so-called third backdrop 7 acting as a groove in a plate-shaped console 8th is formed, is displaceable and is pivotable. The console 8th is at the pole profile 1 attached and has a lower height than the clear height between the pole profile 1 and the sash profile 2 in the closed state.

On the plate-shaped console 8th is still a lever-shaped handlebar 9 around a pivot axis 10 pivoted. How out 5 ersicht Lich, corresponds to the height of the handlebar 9 essentially that of the plate-shaped console 8th so that too the handlebars 9 between the pole profile 1 and the sash profile 2 may be enclosed in the closed state of the frame profile or wing.

The driver 9 has a second backdrop 11 on, essentially in the longitudinal direction of the handlebar 9 runs. Analog goes the third backdrop 7 in the longitudinal direction of the plate-shaped console 8th , The leadership 6 is stored except in the third backdrop in the second backdrop, ie it extends through these two scenes 7 and 11 therethrough. This will be a stroke of the push rod 5 in a pivoting movement of the handlebar 9 and thus the sash profile 2 implemented. For a jam-free adjustment of the sash profile 2 For example, for every possible opening angle between 0 and 60 °, one projects at one of the pivot axis 10 opposite end of the handlebar 9 attached auxiliary leadership role 12 in a first setting 13 , which as a groove part of a plate-shaped auxiliary console 14 which is on the sash profile 2 is attached. The first backdrop 13 runs as shown substantially parallel to the wing profile 2 or adapted to this auxiliary console 14 ,

In contrast to the first backdrop 13 is the second backdrop 11 and less clearly the third backdrop 7 with different sections 17 . 18 respectively. 15 . 16 educated. The sections 17 . 18 will be described below on the basis of 4 and 5 explains in which the frame profile consisting of the pole profile 1 and the sash profile 2 closed is. In this case, a main plane is defined, which runs in the closed state of the frame profile parallel to the pole profile and the wing profile approximately through a building opening, but is not shown in the drawing. The third backdrop 7 that with the pole profile 1 is in a fixed connection, comprises a first section 15 and a second section 16 both substantially parallel to the main plane or the pole profile. By contrast, the second backdrop in the handlebars 9 a first section 17 on, which is only slightly inclined to the main plane, and a subsequent second section 18 which is more inclined to the main plane or a greater slope than the first section 17 having. The second backdrop is in the

4 and 5 through the plate-shaped console 8th hidden and therefore shown with broken lines.

When in the closed position of the frame profile according to the 4 and 5 the linear drive 3 is activated, he pushes the push rod 5 and with this the leadership 6 in the wings 7 and 11 to the left, leaving the scenes 7 . 11 by the force component F1, see 2 , according to their gradient to the main plane slowly, but with large opening moment, swing apart until the leading role 6 to the second sections 16 . 18 the third backdrop or second backdrop, as in the 1 and 2 for the half-open position of the frame profile, ie its wing profile 2 shown.

Upon further activation of the linear drive 3 becomes the wing profile with the force component F1 in the same direction 2 according to 3 further opened, due to the slope of the sections spread apart 16 . 18 faster to the example 60 °, where the lead role 6 at the end of the second sections 16 . 18 the third backdrop or second backdrop passes.

Conversely, the wing profile is reversed 2 closed again, the force component F2, see 2 , arises when the linear actuator 3 the push rod 5 in the drawing retracts to the right. The closing movement will be close to the closed position of the sash as a result of the design of the first sections 15 . 17 braked the third backdrop or second backdrop and the closing moment is great for securely closing the wing.

The second embodiment of the actuator according to the 6 - 10 differs from the first embodiment described above according to the 1 - 5 in that the linear drive 3 instead of the pivot axis 4 on the sash profile 2 here about a pivot axis 19 on the pole profile 1 is pivotally mounted. Accordingly, the described operation remains substantially the same, wherein the direction of movement of the push rod 5 during the stroke of the linear drive 3 remains essentially the same according to the course of the third backdrop 7 in the plate-shaped console 8th , Because of this, the linear drive needs only a small angle around the pivot axis 19 to pan. Furthermore, an advantage of the arrangement of the actuating device in the second embodiment can be seen in the fact that the linear drive remains largely concealed by the pole profile, at least in a lateral view, when the frame profile or the wing is open.

In the third embodiment according to the 11 - 15 is the linear drive 3 also around the swivel axis 19 swiveling on the pole profile 1 stored, however, are compared to the first embodiment, the arrangement of the plate-shaped console 8th that's here on the wing profile 2 attached, as well as the auxiliary console 14 who are here at the pole profile 1 is attached, and over the handlebars 9 with the console 8th communicates, reversed. Accordingly, the basic operation of the third embodiment is the same as that of the first embodiment and the second embodiment, but in the third embodiment, the linear drive 3 especially in the area of the pivot axis 19 is less moved than in the first embodiment, in which the pivot axis 4 on the swiveling sash profile 2 is appropriate.

In the fourth embodiment according to the 16 - 20 is the linear drive 3 around the pivot axis 4 on the sash profile 2 pivoted and also the plate-shaped console 8th with the third backdrop 7 is on the wing profile 2 appropriate. By contrast, the first backdrop 13 on the pole profile 1 assembled. Here, therefore, the floor profile is largely free of attached to him elements of the actuator. The basic operation is the same as in the other three embodiments of the actuator discussed above.

The fifth embodiment of the actuator according to the 21 - 24 differs from the four embodiments discussed above in that the third backdrop 20 and the second backdrop 21 are shaped as steady curves. In other words: sections of different slope of the second backdrop 21 or the third backdrop 20 are constantly merging. To clarify the first section of the second backdrop 21 is their beginning with 44 designated and their end with 45 where the second section begins. With the steady curves of the two scenes 20 and 21 a particularly low-wear actuator is achieved, which is characterized by a continuous movement during opening and closing, with the principle of maintaining the benefits of different slopes of the backdrop - based on the direction of movement of the lifting rod 22 of the linear drive 23 - result. The third backdrop is again part of a plate-shaped console 24 in the embodiment shown on the pole profile 1 is attached. The second backdrop 21 is in a handlebar 25 formed, which is about the pivot axis 25a is pivotable and has an auxiliary guide roller 26a in a plate-shaped auxiliary console 26 with a first, straight, substantially parallel to the sash profile 2 running backdrop or auxiliary scene 27 with the sash profile 2 communicates. On the handlebar 25 as well as on the console 24 grab the lift rod 22 of the linear drive 23 over a carriage 28 on, with two guide rollers 29 . 30 in the third scenery 20 slidably but not pivotally or rotatably guided and with a third leadership role 31 in the second setting 21 intervenes. The third leading role 31 lets a pivoting movement of the handlebar 25 to.

With the illustrated shape of the second backdrop and the third backdrop in conjunction with the carriage 28 should the sash profile 2 from the in 23 shown closed position in the in 21 shown half-open position and beyond, until the third leading role 31 the end 45 the first section of the second set 21 achieved, be swiveled slowly and with great opening moment. Only afterwards, if the third leadership role 31 over the end 45 the second section of the second backdrop 21 goes out into its third section, the sash profile 2 quickly continue with, however, less opening moment in the in 22 pivoted end position shown. In the last movement phase before reaching the end position, the sash profile is to be braked and securely held in the fully open position, which is for example 60 °.

From the 23 and 24 is particularly evident, as the between the floor profile 1 and the sash profile 2 The cavity formed by the frame profile is filled by the quasi-folded actuator. This is not least the downside end of the third backdrop 20 which corresponds to the first section of this scenery. In the closed state of the floor profile of the carriage is in this end portion of the third backdrop 20 lowered.

In the sixth embodiment, the actuating device is located between a substantially vertically installed pole profile 32 and one about a pivot axis 33a swiveling sash profile 33 after the 25 to 27 arranged.

The peculiarity of the sixth embodiment is that a push rod 34 not directly on a leadership role serving as a guide element 35 is hinged, but via an auxiliary push rod 37 whose with the push rod 34 connected end in a subsidiary setting 38 by means of another leadership role 39 is guided. The auxiliary scene 38 , which serves as another groove in a console mounted on the pole profile 40 may be formed, in addition to the third backdrop mentioned above, the here with 41 is designated, extends substantially in the direction of the auxiliary push rod 37 and also the third backdrop 41 , In the third backdrop 41 is the leadership 36 led, which also in the second backdrop 42 in the handlebars 43 is arranged, engages. The actuator is completed by the first link, the one on the wing profile 33 attached console is formed. This first scenery as well as the console, from which it is formed, are in the 25 to 27 not recognizable, because covered by the sash profile. On the other hand, for visualization of the elements described above on the floor profile 32 Parts of it cut out.

With this arrangement of the auxiliary push rod 37 which at one end in the auxiliary scene 38 is guided and at the other end at the leadership role 36 is articulated as a guide element, the point of application of the push rod is moved to the guide element.

The additional effort for the auxiliary scenes 38 is partially offset by the third backdrop 41 may be shorter than in the first to fifth embodiments.

In the further open state of the sash profile 33 according to 26 is the training of the auxiliary scene 38 particularly recognizable.

In the closed state of the wing profile according to 27 the actuator is fully within the between the pole profile despite the additional auxiliary push rod 32 and the sash profile 33 formed space from the outside not recognizable housed. The pole profile 32 is also shown here for illustration broken up.
