Description

The present invention relates to a swing door operator for both 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, which are either to be mounted on a door leaf or on the outside of a door frame or a wall or sunk in the ground under the door. The known door operators are usually made of a cast housing, in which a closing spring and a drive mechanism is housed. An output shaft extends out of the casting housing. On this output shaft, a lever is mounted outside of the cast housing. This lever transmits the force on the door leaf or door leaf on the door frame. In floor mounting, the output shaft 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 swing door operator, which allows a simple and cost-effective production and assembly of a modular design.

The object is achieved by the features of claim 1. The dependent claims have advantageous developments of the invention to the object.

Thus, the object is achieved by a rotary door operator, comprising a housing with a base plate, a driven plate rotatably mounted on the base plate about an output shaft output shaft, wherein the output shaft is formed for rotationally fixed connection with a lever or for direct, rotationally fixed connection with a rotational axis of the swing door a spring unit disposed in the housing as energy storage for a closing or opening movement of the swing door, wherein the spring unit is connected to the output drive for mutual power transmission, and at least one arranged in the housing damper for damping the closing and / or opening movement of the swing door, wherein 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, there is usually talk of a damper. Likewise, it is preferably provided that a plurality of dampers are arranged both in parallel and in series.

In the known door actuators, the housing is always formed as a casting. As a rule, there is a cylindrical bore in the casting. In turn, a hydraulic damping piston is guided in this cylindrical bore. In the present invention, for cost reasons, no fluid or gas-tight housing should be used. Thus, the damper must be designed here as an independent, inherently dense module. Particularly preferably it is provided that no part of the damper is formed integrally with the housing or a housing component, and / or that no part of the damper with the housing or a housing component is urgeformt, and / or that no part of the damper in the housing or a Housing component was molded. Furthermore, it is particularly preferably 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 full 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 the swing door operator comprises a base plate opposite cover plate. In particular, the driven pulley, the spring unit and the damper together with the transfer unit is located between the base plate and the cover plate. Particularly preferred is / are one or more spacers in the form of a plastic part and / or a metal sleeve between the base plate and cover plate arranged.

It is preferably provided that the output shaft comprises an integral with the driven pulley or with the driven pulley rotatably connected 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 inside 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 axis of rotation of the door leaf (at floor mounting). Preferably, the shaft extends through the cover plate and the base plate. Thus, the door operator can be used on both sides, ie for DIN left and DIN right.

Particularly preferably, the housing, in particular the connection of base plate and cover plate, not formed fluid-tight and not gas-tight. The fact that the damper is used as an independent and self-contained module, it requires no dense execution of the housing. As a result, the rotary door operator according to the invention can be made very simple and inexpensive. 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 +/- 2 mm, 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 driven pulley on the lateral surface comprises a control cam, in particular 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 swing door operator further comprises a pressure roller for transmitting power between the spring unit and the driven pulley and / or for transmitting power between the dampening 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 designed as a gear. With the driven pulley is then another gear or a rack engaged. Through this additional gear or the rack we transfer the force to the spring unit.

In a preferred embodiment, the swing door operator comprises a transmission unit for mutual power transmission between the driven pulley and the damper. As an alternative to the transmission unit, the damper can also 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 translation to the spring unit and the damper, a separate transmission unit is preferably used for power transmission between damper and 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 guided damping piston.

In a further preferred embodiment, a fixed end of the damper is rigid or rotatably mounted in the housing, in particular on the base plate. 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 fixed or rotatably mounted in the housing.

In a preferred embodiment of the transmission unit is provided that this comprises a non-rotatably connected to the driven pulley transmission gear or Übertragungszahnradsegment and connected to at least one damper rack. The transmission gear or transmission gear segment is either made in one piece with the driven pulley or is firmly connected to the driven pulley. In particular, the transmission gear and the transmission gear segment and the driven pulley are arranged coaxially. Particularly preferably, a transmission gear or transmission gear segment is arranged on each side of the driven pulley. In a corresponding manner, the transmission unit then comprises two toothed racks which are in each case in engagement with a transmission gear or transmission gear segment. The two racks may be preferably rigidly interconnected. This double design ensures symmetrical loading of the transfer unit and consequently avoids jamming of the transfer unit. The transmission unit is preferably mounted linearly in the housing, in particular on the base plate. The damper used dampens here preferably both in tension and compression direction. The linear guide is designed either as a sliding guide or as a roller guide with rolling or sliding bearings. As a further alternative here is preferably a Wälzkörperlagerung used. The advantage of this rack and pinion drive is that in both directions (opening and closing movement of the door) force and movement can be transmitted. This makes it possible in a simple way to damp with a damper in both directions of movement of the door operator. The rack and pinion drive is relatively low friction, so that achieved a high efficiency of the door operator can be. Furthermore, this solution is inexpensive to implement, because on the rack only the damping forces must be transmitted.

Preferably, the rack or the rack damper are attached on both sides. The two dampers attenuate only in one direction, preferably in the printing direction. This arrangement makes it possible to use very simple and inexpensive dampers which only have to dampen in one direction.

Furthermore, it is preferred that the transmission unit comprises a transmission sprocket or transmission sprocket segment rotatably connected to the driven pulley and a tension and / or pressure chain connected to the damper. The transmission sprocket or transmission sprocket segment is in particular formed as a fixed component of the driven pulley and is consequently either manufactured in one piece with the driven pulley or is located directly on the driven pulley. In particular, the transmission sprocket or transmission sprocket segment are arranged coaxially with the driven pulley. The transmission unit here preferably comprises a chain guide. This can for example consist of two jaws, which are mounted in the housing, in particular on the base plate. Between these two two jaws the chain is guided. The damping piston used here can attenuate in both directions, in particular when using a tensile and compressive chain. At one end, the damper is in turn fixed or rotatably connected to the housing. The other end, in particular the piston rod, is connected to the chain. In particular, thanks to the leadership here also compressive forces can be transmitted. In this case one speaks of a push chain or pull / pressure chain. In particular, such a push chain is realized by a flexible band with threaded support elements, similar to a string of pearls. By this embodiment, both the damping of the opening movement and the damping of the closing movement of the door can be achieved without much additional measures. The ratio between the rotational movement of the driven pulley and the stroke movement of the damper can be freely adjusted via the diameter of the transmission sprocket. Very large translations of i = 3 can be realized here. By winding the chain only little space is required for this embodiment. Furthermore, this solution is very low friction, so that can be built in this way a door operator with high efficiency.

In a further preferred embodiment, it is provided that the transmission unit comprises a transmitting pulley rotatably connected to the Abtrebscheibe and connected to the damper traction means, in particular cable. The transmission cable pulley is Favor solid part of the driven pulley. Thus, the transmission sheave is either made in one piece with the driven pulley or placed directly on the driven pulley. The transmission sheave and the driven pulley are particularly preferably arranged coaxially. The damper is loaded in this embodiment only to train and attenuates consequently only in this direction. The damper is designed so that it moves back in the printing direction by itself. Again, the damper is fixedly or non-rotatably connected to the housing at one end. The other end, in particular the piston rod, is connected to the traction means, in particular rope or band or belt or chain. The transmission cable pulley is designed in particular as a cam disk or pulley. By the rotational movement of the driven pulley, the winding of the traction means is effected. Here, depending on the direction of rotation of the driven pulley either an opening movement or closing movement of the door can be damped. In order to dampen both directions, the opening and closing movement, it is preferably provided that the door operator comprises two dampers. In this case, one end of the traction means is preferably connected to a damper and the other end of the same traction means connected to the other damper. The two dampers can preferably both be arranged on one side of the transfer pulley, preferably on the side of the spring unit, or a damper can be arranged on each side of the transfer pulley. Particularly preferably, the traction means is guided in a groove of the transmission sheave. All embodiments with the transmission sheave can be realized very easily and inexpensively. The ratio between the rotational movement of the driven pulley and the stroke movement of the damper or damper can be adjusted freely via the diameter of the transmission sheave. Here also relatively large translations of i = 3 can be realized. By winding the traction means only little space for this solution is needed. Furthermore, these solutions are very low friction, so that can be realized in this way a door operator with high efficiency.

In a further preferred embodiment of the transmission unit, this comprises a connecting rod, which is mounted eccentrically on one end of the driven pulley. The connecting rod is connected to the damper at the other end. Particularly preferred here comprises the transmission unit at the junction of connecting rod and damper a leadership role. Fixed to the housing, in particular the base plate, connected to a roller guide. At this roller guide, the guide roller is guided. The guide can either be straight or curved in order to influence the course of the translation. To the output shaft around, in particular concentric with the Output disc, there is a Andrückkontur on the driven pulley. This Andrückkontur is particularly designed as projecting from the driven pulley in the direction of the output shaft ring or ring segment. The connecting rod is, between its eccentric bearing and the end connected to the damper, to the Andrückkontur. About this Andrückkontur the force between the connecting rod and driven pulley is transmitted. This simple and robust design allows for damping in both directions. Here, translations up to i = 3 can preferably be made possible. In particular, here is the translation and thus the damping at small opening angles of the swing door large.

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 is mounted here either rigid or rotatable. The other, linearly movable end of the spring unit is, as already described, either via a pressure roller connected to the control cam of the driven pulley or is connected via a rack / pinion gear with the Abtrebscheibe. 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 the springs and the storage of the fixed end is preferably a Federverstelleinheit 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 preferred is the swing door operator, in particular the spring unit and the driven pulley, 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 a mounting point for the housing on the lintel. That is, for example, a screwing of the swing door operator with the fall of a door frame passes through the fixed or rotatable mounting of the fixed end of the damper.
