Description

The present invention relates to a Drehfiügeltürbetätiger both for the standard installation on door leaf, door frame or wall and for the recessed in the ground mounting.

The prior art knows door closers and door openers that are either mounted on a door panel or on the outside of a door frame or a wall or sunk in the ground unier the door. The previously known Türbetätiger exist in the rain! from a cast housing, in which a closing spring and a Antnebsmechanik is housed, From the cast housing out extends an output shaft. On this Abthebsachse a lever is mounted outside of the cast housing. This lever transmits the force to the door leaf or from the Türbfatt on the door frame. For floor mounting, the axis of movement of the door operator is directly connected to the axis of rotation of the door leaf. These prior art door operators are complex and expensive to manufacture due to the cast housing. Furthermore, the cast housing opposes a modular design. Thus, the installation space for the damping and the suspension is always fixed by the mold.

It is an object of the present invention to provide a rotary door operator, which allows a simple and cost-effective production and assembly of a modular design.

The object is achieved by the Merkmaie of claim 1. The dependent claims have advantageous developments of the invention to the object. Thus, the object is achieved by a swing door operator, comprising a housing with a base plate, a Ablenkscheibe rotatably mounted on the base plate about a driven axis Abinebscheibe, the Ab- axis for rotationally fixed connection with a lever or for direct, rotationally fixed connection with a rotational axis of the swing door formed is a spring unit disposed in the housing as an energy storage for a closing or opening movement of the swing door, wherein the spring unit is connected to each other for transmitting power to the driven pulley, and at least one housing disposed in the damper for damping the closing and / or opening movement of the swing door, said the damper for mutual transmission of power is connected to the driven pulley, and is formed as a separate, independent of the housing module. In the following, for reasons of clarity, the term "damper" is used. Likewise, it is preferably provided that a plurality of dampers are arranged both in parallel and in series.

In the previously known door actuators, the housing is always designed as a cast part. As a rule, there is a cylindrical bore in the cast test. In turn, a hydraulic damping piston is guided in this cylindrical bore. For the purposes of the present invention, no fluid-tight or gas-tight housing should be used for reasons of cooling. Thus, the damper must be designed here as an independent, inherently dense module. It is particularly preferred that no part of the damper is integrally formed with the housing or a housing component, and / or that no part of the damper is urgeformt with the housing or a Gehäusebestandfeil, and / or that no part of the damper in the housing or a Housing component was molded. Furthermore, it is particularly preferred provided that the damper is independent of the housing fluid and / or gas-tight. It is further preferred that the damper comprises a damper cylinder filled with gas or fluid and a damping piston guided in the damper cylinder. Furthermore, it is preferably provided that the spring unit always acts against the damper, so that the complete opening and / or closing of the swing door is damped. Further preferably, the damper or dampen the complete opening movement and / or the complete closing movement of the swing door. Particularly preferably, the damper or dampers are designed so that they dampen to train and / or pressure.

Preferably, the housing of Drehdrehitürbetätigers comprises a base plate opposite cover plate. In particular, the driven pulley, the spring unit and the damper together with Überiragungs- unit between base plate and cover plate. Particularly preferred is / are one or more Abstandshaiter arranged in the form of Kunstsfoffteils and / or a fvletallhüise between base plate and cover plate. It is preferably provided that the Abiriebsachse comprises a one-piece with the driven pulley or rotatably connected to the driven pulley shaft, wherein the shaft is mounted in the base plate and / or cover plate by means of sliding or rolling bearings. Preferably, a thrust washer is arranged on the inner soap of the cover plate instead of the rolling or sliding bearing in the cover plate. Preferably, the shaft extends through the cover plate and / or base plate and thus provides an interface for the lever or directly for the rotational axis of the door leaf (bottom mounting}.) Preferably, the shaft extends through the cover plate and the base plate , ie for DIN links and DIN right, are used. Particularly preferably, the housing, in particular the connection of the base plate and cover plate, not formed fiuiddicht and not gas-tight, characterized in that the damper is used as an independent and self-tight module, it requires no dense execution of the housing ses. As a result, the Drehfiügeitürbetätiger invention can be very easily and inexpensively manufactured. Alternatively, particularly for a floor spring, the housing may be fluid tight to prevent ingress of moisture. Particularly preferably it is provided that the base plate and / or cover plate, each with a uniform wall thickness, in particular equal to or less than 5 mm, in particular equal to or less than 3 mm, are executed, wherein wall thicknesses with deviations of +/- 2mm, in particular +/- 1 mm, are still defined as uniform wall thicknesses. Particularly preferably, the base plate and / or the cover plate are made of sheet metal or plastic. In a further preferred embodiment, it is provided that the output disk on the lateral surface comprises a control cam, in particular a cam contour. Under cam contour is to be understood that the radius of the driven pulley changes continuously at least in a certain area. The Drehfiügeitürbetätiger further comprises a pressure roller for power transmission between the spring unit and the driven pulley and / or for transmitting power between the damping and the driven pulley. This pressure roller rolls on the control cam of the driven pulley.

As an alternative to this power transmission by means of cam contour and pressure roller, it is preferably provided that the driven pulley comprises a toothed wheel contour. Here, the lateral surface of the driven pulley is formed as a gear. With the driven pulley is then another gear or a Rack engaged. Above this additional gear or the rack we transfer the force to the spring unit.

In a preferred embodiment, the Drehdrehitürbetätiger comprises a transfer unit for mutual power transmission between the driven pulley and the damper. The damper can be connected directly to the spring unit. Here, it is then preferably provided that one end of the damper is fixedly connected to a linearly movable end of the spring unit and the other end of the damper is fixedly connected to a fixed end of the spring unit. In this arrangement, the spring travel and damper travel are identical. However, in order to achieve a different transmission to the spring unit and the damper, a separate transmission unit is preferably used for transmitting power between the damper and the driven pulley.

It is particularly preferably provided that the transmission unit is designed for the conversion between the rotational movement of the driven pulley and a linear damping movement of the damper. Here we recommend a damper, consisting of cylinder and damping piston guided in it.

In a further preferred embodiment, a fixed end of the damper is rigid or drehbewegfich in the housing, in particular on the base plate mounted. The other, linearly movable end is connected to the transmission unit, in a particularly preferred embodiment, the movable end of the damper is the piston rod, which is connected to the damping piston. The cylinder of the damper is then stored firmly or rotatably in the housing. In a preferred embodiment of the transmission unit is provided that the transmission unit comprises a first rocker, wherein one end of the first rocker is rotatably mounted in the housing, in particular on the base plate, and the other end of the first rocker is connected to the damper. Further, the first rocker is connected between its two ends for mutual power transmission with the pressure roller.

The damper is here in the simplest variant designed so that it only dampens to train or pressure. In the other direction, the damper can move back freely. The damper is rotatably mounted at its fixed end relative to the housing. The connection between the rocker and the movable end of the damper is also rotatable. The axes of rotation of these bearings are in particular parallel to the output axis.

Due to the different distances on the one hand of the connection between the pressure roller and rocker to the fixed bearing of the rocker and the other of the connection between the rocker and damper for fixed mounting of the rocker results in a translation between the pressure roller and the damper, so that a large stroke on Damper can be realized. In turn, the damping force of the damper, based on the pressure roller, reinforced. Here are preferred typical ratios of about i = 2 possible. Since it is difficult to build a dampening piston for small strokes and large forces, this ratio is advantageous. The setting of the opening and closing speed can be done via the damper. The stroke and thus the adjustable displaced volume is increased by this arrangement. Furthermore, it is preferably provided that the transmission unit comprises a traction means, in particular a cable pull. The train center! is connected at one end to the damper and can be wound at the other end onto the cam contour of the Äbtriebscheibe or on a non-rotatably connected to the Abthebscheibe transfer sheave. By supplementing the simple swing arrangement with the traction means, a force can be transmitted to the damper both in the opening and closing direction of the door. The damper is here preferably designed so that it dampens both train and pressure. Preferably, the rocker transmits the force in the direction of pressure on the damper. The traction device, which winds on the transmission sheave or on the cam contour of the Äbtriebscheibe loads the damper on train.

It is further preferred that the transmission unit comprises a counter-slide and a second rocker. The Gegenroiie waltz against the pressure roller on the cam contour, the Äbtriebscheibe. One end of the second rocker is rotatably mounted in the housing, in particular on the base plate. The other end of the second rocker is directly or indirectly connected to the damper. Furthermore, the second rocker is connected between its two ends for mutual transmission with the Gegenroiie, The arrangement thus shows a counter-roller on one side of the Äbtriebscheibe and a pressure roller on the other side of the Äbtriebscheibe. On both roles attacks a swingarm.

The two wings are either rigid (first variant) or connected to each other by means of another damper (second variant). Particularly preferred in the second variant, the one rocker with a cylinder of the other damper and the other rocker connected to the piston rod of the other damper. When connecting the two wings with another damper, it is possible to use the other damper, which connects the two wings together To perform damping elastomer, since only a small stroke occurs or may occur.

In the first variant with the rigid connection (also called coupling rod), damping forces can be transmitted between damper and driven pulley in both directions. If the rollers are the same size, the driven pulley should preferably be made of the same thickness. When using a damper as a connection between the two wings, the driven pulley does not have to be made of a uniform thickness.

In a further advantageous embodiment, it is provided that the connection between the pressure roller and the first rocker and / or the connection between the counter roller and the second rocker comprises a rotational and a linear degree of freedom. In particular, this is achieved by a bolt of the pressure roller or counter-roller is guided in a Langioch the first and second rocker. Alternatively, it is preferably provided that the connection between the pressure roller and the first rocker and / or the connection between the counterroil and the second rocker comprises only one rotational degree of freedom and no linear degree of freedom,

Furthermore, it is preferably provided that a fixed end of the spring unit is mounted on the housing, in particular on the base plate. This fixed end of the spring unit here is either rigid or rotatably mounted. The other, linearly movable end of the spring unit is, as already described, either connected via a pressure roller to the control cam of the driven pulley or is connected via a rack / gear ratio with the driven pulley. The linearly movable end of the spring unit is particularly preferably mounted in a slot and / or in a groove and / or on a web of the housing, in particular the base plate, linearly movable. Between the spring and the springs and the storage of the fixed end is preferably a spring adjustment unit for adjusting the closing force.

The spring unit particularly preferably comprises several, in particular two or three, compression springs arranged in parallel. More preferably, the spring unit comprises at the fixed end and / or at the linearly movable end depending on a compression spring receptacle. The compression spring or the plurality of compression springs are inserted into pockets of the compression spring receptacle or are plugged onto bolts of the compression spring receptacle. Particularly preferably, all compression springs are connected to a common compression spring receptacle on the linearly movable end and / or on the fixed end. Thus, an equal spring travel of all compression springs is always ensured.

Particularly preferably, the rotary door component, in particular the spring unit and the Äbtriebscheibe, for moving the swing door over at least 45 °, in particular at least 90 °, in particular at least 120 ° formed.

It is particularly preferably provided that a bearing point of the driven pulley and / or a damper and / or the spring unit in the housing is simultaneously formed as fvionfagepunkt for the housing on the lintel. This means, for example, that a screw connection of the rotary door opener with the fall of a door frame passes through the fixed or rotatable mounting of the fixed end of the damper.

When using the door operator 1 as a standard door closer or door opener, a lever on the lever eye 69 rotatably connected to the Äbtriebsachse 4. The other end of the lever is supported for example on a slide rail on the door or door frame. When using the door operator 1 as a floor spring, a rotation axis of the door leaf, in particular coaxially, directly connected via this eye 69 with the Äbtriebsachse 4 rotatably.

As can be seen in particular in FIGS. 8 and 9, the shaft 75 extends through the base plate 3 or a cover plate 85 therethrough. As a result, the lever eye 89 is also accessible outside of the housing 2. In a particularly preferred embodiment, the shaft 75 extends out of the housing 2 in both directions. This means that the shaft 75 breaks through both the base plate 2 and the cover plate 85. Thus, the door operator 1 can be used on both sides, ie for DIN right and DIN links.

Furthermore, the door operator 1 comprises a spring unit 7, a transfer unit 8 and a damper 9. A pressure roller 11 is provided for transmitting power between the spring unit 7 and the driven pulley 5. see. The spring unit 7 and the transmission unit 8 are also mounted on the base plate 3 here. Alternatively, it is also possible to store these elements on the cover plate 85. The spring unit 7 comprises two juxtaposed and parallel compression springs 12. Further, the spring unit 7 comprises a linearly movable end 13, formed as a first compression spring receptacle, and a fixed end 14, formed as a second compression spring receptacle. The second compression spring receptacle 14 comprises a Federversteileinheit 15 for adjusting the closing force of the spring unit 7. The first compression spring receptacle 13 is mounted linearly movable with a linear bearing 18 of the spring unit 7 relative to the base plate 3. The second compression spring receptacle 14 is mounted with a rigid or rotatable bearing 17 of the spring unit 7 relative to the base plate 3.

The damper 9 comprises a damper 18 and a damper cylinder 18 guided in the damper piston 19. The damping piston 19 is connected to a damper piston rod 20. The damper cylinder 18 is mounted by means of a rigid or rotatable bearing 21 of the damper 9 relative to the base plate 3. At the free end of the damper piston rod 20 is the connection 22 to the transmission unit 8. The connection 22 between damper 9 and transmission unit 8 can be rotatably, in particular with a rotation axis parallel to the output axis 4, or rigid.

The transmission unit 8 comprises a first rocker 55. This first rocker comprises at one end a first rocker arm 58 as a rotatable bearing of the rocker 55 relative to the housing 2, in particular the base plate 3. At its other end, the rocker 55 via the connection 22 with the Damper 9 connected. Between her both ends, that is, between the first swing arm bearing 58 and the connection 22, the first rocker 55 for gegenseifigen power transmission of the pressure roller 11 is connected, Fig. 2 shows the transmission unit 8 according to the first embodiment in detail. You can see here the Druckrolte 11, which rolls on the control cam 32 of the Abtnebscheibe 5. The rocker 55 has between its two ends a slot 57. The pressure roller 11 comprises a pressure roller axis 30. This Druckroilenachse 30, designed as a bolt, is guided in the slot 57. By rotating the driven pulley 5, the pressure roller 11 moves. The force is transmitted to the rocker 55 via the Druckroilenachse 30 and the slot 57. As a result, the piston rod 20 is moved via the connection 22 and as a result the movement is damped.

The output disk 5 has on its lateral surface a control cam, in particular cam contour 32, designed here as a heart-shaped cam contour on. The pressure roller 11 rolls on this cam contour 32. Various exemplary embodiments of the transmission unit 8 will be shown below with reference to FIGS. The same or functionally identical components are provided with the same reference numerals as in the first embodiment. These embodiments always correspond in their function and in their construction to the first embodiment. with the exception of the transmission unit The spring unit 7 and / or the pressure roller 8 are here in particular often shown only schematically or hidden for clarity. Ultimately, however, results in the entire construction of the respective door operator 1 in all embodiments in combination with the illustration of FIG. 1st FIG. 3 shows the transmission unit 8 according to the second exemplary embodiment. Here, it is first shown how the spring unit 7 is connected with its compression spring receptacle 13 to the pressure profile 11. The connection between pressure roller 11 and spring unit 7 is not shown in all embodiments, but applies in a corresponding manner to all embodiments. The compression spring receptacle 13 comprises two parabolic and spaced plates. Between these two plates, the pressure roller 1 1 is arranged. Each of the two plates comprises a fork opening 31 in this fork opening 31 is the pressure roller axis 30 and thus also the pressure roller 1 1 stored.

Furthermore, this Ausführungsbeispiei shows a second rocker assembly comprising a Gegenroüe 48, which also rotates relative to the pressure roller 1 1 on the control cam 32 of the driven pulley 5. From the counter-roller 48, the force is transmitted to a second rocker 58. The second rocker 58 is rotatably mounted at one end via a second rocker bearing 59 in the housing 2, in particular on the base plate 3. At the other end, the second rocker 58 is connected to the connector {coupler clip) 81 via the connection 34. Between the connection 34 to the coupling rod 81 and the second rocker bearing 59, the second rocker 58 comprises a second elongated hole 80. In this second elongated hole 80, a counterroof axis 49, designed as a bolt, is guided. The two linearly movable ends of the two rockers 55, 58 are connected via the coupling rod 61, Through this connection via the coupling rod 61, a damping force can be transmitted both in the opening and in the closing direction of the door. 4 shows the transmission unit 8 according to a third embodiment. This embodiment corresponds to the second embodiment except for the head bar 61. Here, instead of the coupling rod 61, a further damper 33 is provided. The further damper 33 umiasst, comparable to the first damper 9, a damper cylinder 18. In the damper cylinder 18, a damping piston (not shown) is guided. This damping piston of the further damper 33 is connected to a piston rod 20. About the piston rod 20, the further damper 33 is in turn connected by means of the connection 34 with the second rocker 58. Instead of being shown here, the further damper 33 may also be an elastomer. By using the further damper 33, the Abiriebscheibe 5 does not have to be executed as a uniform thickness, since certain fluctuations in the movement between the first rocker 55 and two rocker 53 can be compensated.

FIG. 5 shows a fourth embodiment of the transfer unit 8. Here again, the pressure roller 11 is connected to the first rocker 55. However, no elongated hole is provided here, but the printing axis 30 is connected to the first rocker 55 only with a rotational degree of freedom. About the driven pulley 5, the pressure roller 11 and the first rocker 55, the damper S is charged to pressure. In order to again dampen the closing and opening direction of the door, a strip 37 is provided here. The cable 37 is connected at one end via the connection 22 with the damper 9. The other end of the Seifzugs 37 is connected via the cable attachment 62 with the driven pulley 5. In the lateral surface of the driven pulley 5 there is a Seiiführungsnut 38. This makes it possible that the cable 37 is wound on the driven pulley 5. Thus, the Seiizug 37 of the damper 9 is also loaded on train. Fig. 8 shows a fifth embodiment of the transmission unit 8. This Ausführungsbeispiei largely corresponds to the fourth embodiment. In this case, however, the cable 37 is not wound onto the driven pulley 5. Rather, here, a transmission sesolirium is fixed against rotation, in particular coaxially connected to the driven pulley 5. The cable 37 is consequently connected via the cable attachment 82 with the transmission cable 36. The Seilführungsnut 38 is located in the transmission sheave 38. Here again the damper 9 is loaded on the first rocker 55 to pressure. The cable 37 locks the damper 9 to train.

17a-d show various possibilities for mounting the driven pulley 5 in the housing 2. These bearings are preferably to be applied to all embodiments. Shown in each case is the output disk 5 between the base plate 3 and the cover plate 65,

In FIGS. 7a-d, rolling bearings 87, 88 and plain bearings 68 are presented. However, it is always possible to replace plain bearings by rolling bearings and vice versa. The driven pulley 5 is manufactured either integrally with the shaft 75 in all four variants, or the two components are manufactured separately and connected to one another in a torque-proof manner.

Fig. 7a shows a bearing of the shaft 45 by means of a first roller bearing 87 in the base plate 3 and a second roller bearing 88 in the cover plate 65. The shaft 75 passes through both the base plate 3 and through the cover plate 65 and has both ends a lever eye 89.

Fig. 7b shows the plain bearings 86 as Bundiager. It is shown a floor storage. The shaft 75 is rotatably connected to the driven pulley 5 here. The lever eye 68 rotates together with the driven pulley 5. Fig. 7c shows an embodiment of the shaft 75 as a truncated stump. Here, the worlds 75 extends from the Abiriebscheibe 5 from only in one direction, namely through the base plate 3 therethrough. Opposite the base plate 3, the shaft 75 is mounted mitteis the first roller bearing 87. Between the driven pulley 5 and the cover plate 65 is a thrust washer 70th

FIG. 7d shows a similar bearing as in FIG. 10c, with the exception that instead of the first roller bearing 67 a sliding bearing 66 is used between the shaft 75 and the base plate 3. The sliding bearing 66 is angled here and thus forms an axial bearing of the transmission gear 24. Between the driven pulley 5 and the cover plate 65 in turn the thrust washer 70 is provided. Figs. 8 and 9 show the door operator 1 with a complete housing 2 for all embodiments.

As can be seen in particular in Fig. 8, the cover plate 85 is opposite and parallel to the base plate 3. In addition, the cover plate 65 to the folds 23 of the base plate 3 complementary folds. Fig. 8 shows an example of the first embodiment, the formation of storage and mounting parts directly in the base plate 3. Thus, tabs are bent inwardly, which are used as a linear bearing 16 for the spring unit 7.

9 shows how the housing 2 is provided with a cover 10 for an aesthetically pleasing exclusion. The cover 10 has a recess for the shaft 75. The cover 10 fulfills any supporting or stabilizing function. Bezygszeicheiiliste
