Description

The present invention relates to a swing door operator attachment (hereinafter referred to as attachment) to supplement a door drive and a swing door operator assembly comprising a door drive and the attachment.

The prior art knows door drives which drive via a rotary shaft and a linkage of a revolving door. In this case, the rotary shaft is operated by motor or motor underestimated to open and / or close the door. Often, these door drives have no or only very weak spring energy storage. Furthermore, usually no damper or only a weak damper for the opening and / or closing movement is provided.

It is an object of the present invention to provide a swing door actuator attachment, which complements a door drive to a spring-loaded with simple and cost-effective production and assembly. Preferably, the swing door actuator attachment should allow an opening and / or closing damping.

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 swing door actuator attachment to supplement a door drive, comprising a housing having a base plate, and a rotatably mounted on the base plate about an output shaft driven pulley, wherein the output shaft is formed for rotationally fixed connection with a rotary door driving rotary shaft of the door drive. Furthermore, the attachment comprises a housing arranged in the spring unit as energy storage for a closing or opening movement of the swing door, wherein the spring unit is connected to the mutual power transmission to the driven pulley. By mounting the attachment according to the invention on a door drive, it is sufficient that the door drive only drives the opening or closing direction of the door. The other direction can be driven by means of the spring in the essay. Alternatively, the door drive can also be designed for the motor drive of the opening and closing direction of the door. The spring energy accumulator in the attachment then serves to open or close the door, for example in the event of a power failure and / or in the event of fire.

The previously known door opener or door closer usually consist 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. These prior art door operators are complex and expensive to manufacture due to the cast housing. Furthermore, the cast housing is very high, so that the previously known door openers or door closers are not suitable as an attachment to a door drive. In particular, it requires for the or the damper in the article of the invention a new design. The attachment therefore preferably comprises at least one damper arranged in the housing for damping the closing and / or opening movement of the swing door, wherein the damper is connected to the driven pulley for mutual transmission of power and is designed as a separate module independent of the housing.

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 article according to the invention, for cost reasons, no fluid-tight 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. The use of little or no oil increases the environmental compatibility. 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 attachment comprises a base plate opposite Cover plate. In particular, the driven pulley, the spring unit and the optional damper together with the transfer unit are 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 of the attachment comprises a shaft integral with the driven pulley or rotatably connected to the driven pulley, wherein the shaft is mounted in the base plate and / or cover plate by means of sliding or roller 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 and / or for the rotary shaft of the door drive. Preferably, the shaft extends through the cover plate and the base plate. Thus, the essay can be used on both sides, ie for DIN left and DIN right. Furthermore, thus, the essay can also be mounted between the door drive and the lever or linkage.

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 article according to the invention can be produced very simply and inexpensively.

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 attachment 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 attachment comprises a transmission 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 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 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 shaft.

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 damping piston for small strokes and large forces, this ratio is advantageous. The required damping force on the damper is reduced and the stroke and thus the 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 traction means is connected at one end to the damper and is at the other end on the cam contour of the driven pulley or on a rotatably connected to the driven pulley transmission pulley wound. By supplementing the simple swing arrangement with the traction means, a force can be transmitted to the damper both in the opening and in the 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 compression direction to the damper. The traction device, which winds on the transmission pulley or on the cam contour of the driven pulley, loads the damper in tension.

It is further preferred that the transmission unit comprises a counter-roller and a second rocker. The counter-roller rolls over the pressure roller on the cam contour of the driven pulley. 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. Further, the second rocker is connected between its two ends for mutual power transmission with the counter-roller. The arrangement thus shows a counter-roller on one side of the driven pulley and a pressure roller on the other side of the driven pulley. 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 perform the other damper, which connects the two wings together, as a damping elastomer, since only a small stroke occurs here.

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 designed as a uniform thickness. When using a damper as a connection between the two wings, the driven pulley does not have to be designed as 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 slot of 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 counter roller 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 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 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 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 preferred are on linearly movable end and / or at the fixed end of all compression springs connected to a common compression spring receptacle. Thus, an equal spring travel of all compression springs is always ensured.

Particularly preferably, the attachment, 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 °, is formed.

Particularly preferably it is 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 or on the swing door operator. That is, for example, a screw of the essay with the door drive through the fixed or rotatable mounting of the fixed end of the damper passes.

The invention further comprises a swing door operator assembly comprising a revolving door operator attachment just described and a door operator having a powered or powered rotary shaft for opening and / or closing a revolving door. The previously described advantageous embodiments of the swing door actuator attachment find correspondingly preferred application to the swing door actuator attachment of this arrangement.

Preferably, the dimensions of the attachment in the planes perpendicular to the output axis correspond to the dimensions of the door drive in the planes perpendicular to the rotary shaft. Thus, the two components can be flush with each other.

It is preferably provided that the door drive comprises its own door drive housing. This door drive housing is designed to be closed regardless of the housing of the swing door actuator attachment, so that the door drive would be fully functional even without essay.

In the following, three preferred arrangements of the attachment, the door drive and the linkage are described:
In a first variant, it is provided that the rotary shaft is accessible on a first side of the door drive and a second side opposite the first side, wherein on the first side, the linkage for power transmission with the swing door or a wall is mounted, and wherein on the second side of the swing door operator attachment is mounted. The torque is thus transferred from the attachment via the door drive to the linkage. Preferably, the housing of the attachment is flat on the door drive housing.

In a second variant, it is provided that the output shaft is accessible on a first side of the rotary door operator attachment and a second side opposite the first side, wherein on the first side, the linkage for power transmission with the swing door or a wall is mounted, and wherein on the second side of the door drive is mounted.
