Description

The invention relates to a door operator linkage for mounting on an output shaft of a door operator. Furthermore, the invention shows a door operator assembly and a revolving door assembly, each including the door operator linkage.

Door closers and door drives, which are collectively referred to as door operators, are known from the prior art. Door closers have an energy store, for example a spring. When the door is opened manually by a person, this energy accumulator is charged. When the door is closed, the energy accumulator is discharged. In the prior art there are also door closers with a servo drive, which supports the charging of the energy accumulator when the door is opened. Door drives, on the other hand, have an electric or hydraulic drive that applies the full force to open and/or close a door. In addition to the drive, an energy store can be used in the door drive.

Door operators usually have an output shaft. The output shaft is non-rotatably connected to a door actuator linkage. When mounting the door operator on a door leaf, the door operator linkage transfers the force to the frame or wall. If, on the other hand, the door operator is attached to the frame or wall, the linkage transfers the force to the door leaf. Cable routing through the door operator linkage or along the door operator linkage is desirable in various applications. One or more cables can be laid along the cable routing for both data transmission and power supply. For example, such a drive in Door actuators are supplied with energy and / or are controlled. But even when the door operator is mounted on the wall or frame, power can be supplied via the cable routing, for example to a door lock; it is also possible to exchange data with the door operator, door lock or any other element on the door leaf via the cable routing.

It is the object of the present invention to specify a door-actuator linkage which, with a simple structure, enables reliable and low-maintenance operation of a door. In particular, the door actuator linkage should enable safe cable routing.

The object is solved by the features of the independent claims. The dependent claims relate to advantageous configurations of the invention.

The invention shows a door operator linkage with a lever and a linkage head. The lever extends along a longitudinal axis. In particular, the longitudinal axis sits in the center of the lever. One end of the lever is connected, for example, to a slide that is guided in a slide rail. Alternatively, this end of the lever can also be rotatably connected to another lever, so that these two levers together form a scissor linkage. The other end of the lever goes into the linkage head of the door operator linkage with a bend.

The linkage head is designed for non-rotatable mounting on an output shaft of a door operator. In particular, the linkage head is slipped onto the output shaft of a door operator and is thus connected to the output shaft in a torque-proof manner. To describe the invention is a Shaft axis of the output shaft of the door operator defined. The position and alignment of the shaft axis also results from the design of the rod end. The door operator can basically be a door closer, servo door closer or door drive.

The offset between the lever and the linkage head creates a shoulder. When the door operator is mounted on the door leaf, the lever extends beyond the door leaf to the output shaft of the door operator. The door operator or the output shaft is usually located slightly lower than the top edge of the door leaf. The result of this is that the shoulder created by the offset reaches behind the door leaf.

At the same time as the shoulder, the offset creates a free space which, according to the invention, is designed for cable routing. In particular, the door operator linkage comprises at least one cable and this cable runs through the free space.

The clearance is limited by the linkage head and by a cranked area of the lever. The offset surface of the lever is in particular a surface facing the shaft axis. In particular, the offset surface is created by the lever ending or being bent downwards in the area of the offset. In particular, the offset surface merges into the upper side of the rod head.

When the door operator is mounted on the door leaf, the output shaft to be used protrudes upwards out of the door operator. Accordingly, the linkage head is located above the door operator. The free space defined here is thus limited on its underside by the rod head. The offset surface forms a lateral boundary. The free space can go upwards, i.e. on the side opposite the rod head remain theoretically open. However, it is preferably provided that a corresponding free space cladding closes the free space on the upper side.

The offset surface forms a limitation of the free space on one side only. Another side, which is in particular semi-circular, can be delimited by a corresponding radial covering.

The elements "lever" and "linkage head" described here describe in particular only the corresponding load-bearing components of the door operator linkage. The lever and/or the linkage head may be completely or partially surrounded by a fairing. In particular, the lever and the linkage head are made of metal. The lever and the linkage head can be made in one piece or can be two components connected to one another. The surrounding panel is made in particular of plastic; but can also be made of sheet metal. In order to describe the position of the cover, the terms radial cover, free space cover and lever cover are used within the scope of the invention. These panels can be connected to one another in one piece or represent separate components. In particular, the lever fairing is located on one or more sides of the lever. As will be described in detail below, a cable duct can be formed in the lever and/or between the lever and its lever casing and/or in the lever casing. The at least one cable routed through the free space is routed further in this cable duct along the lever and thus parallel to the longitudinal axis. From the free space, the cable or a corresponding additional cable is preferably routed parallel to the shaft axis in the direction of the door operator and is preferably connected to electronics and/or electrics in the door operator.

When using the door operator linkage on a door operator, the linkage head together with the lever rotates together with the output shaft relative to the remaining components of the door operator; Depending on the application, a rotary movement of up to 180° can occur here. As a result of this rotary movement, the at least one cable moves or bends in the free space. In order to enable the largest possible bending radii of the cable in the free space, the free space is preferably designed to be as large as possible. In particular, this relates to the expansion of the free space in a plane perpendicular to the shaft axis. At the same time, however, the size of the free space is limited by the offset. The cranking must be positioned as close as possible to the linkage head, so that the shoulder resulting from the cranking is also positioned as close as possible to the linkage head or the shaft axis and can thus reach behind the door leaf. In addition, the door operator linkage must be sufficiently stable at the transition from the lever to the linkage head in order to transfer the corresponding forces.

An imaginary boundary surface is preferably defined for the further development of the offset. This imaginary interface is perpendicular to the longitudinal axis of the lever. The interface is in particular vertical and thus parallel to the shaft axis. The lever protrudes in the direction of the linkage head or in the direction of the shaft axis up to this imaginary boundary surface. The end of the lever facing the rod end thus defines the position of this imaginary interface. In particular, the offset surface of the lever, that is to say the surface laterally delimiting the free space, projects up to this imaginary boundary surface. With a maximally large design of the lever and thus with a design that is optimal in terms of stability, the lever would protrude with its entire cranked surface up to this boundary surface. In the context of the invention it is preferably provided that the Offset surface is partially withdrawn from this interface, so as to expand the space. The lever, in particular the cranked surface, thus protrudes at least with a tip up to the boundary surface. However, the entire offset surface does not overlap with the imaginary boundary surface, but only at least one point on the offset surface.

In an alternative formulation, it is defined that the offset surface is preferably not perpendicular to the longitudinal axis of the lever over its entire area.

Furthermore, it is preferably defined that the top of the lever is higher than the top of the linkage head and this difference in height determines the height of the free space. The offset surface preferably transitions into the upper side of the linkage head on the one hand and into the upper side of the lever on the other. Furthermore, it is preferably provided that the underside of the linkage head, ie the side facing the door operator, is lower than the underside of the lever.

Provision is preferably made for the offset surface to have an inclined section. The inclined section can extend over the entire cranked surface, so that the entire cranked surface is configured in an inclined manner. Alternatively, it is also possible for the inclined section to extend over only a part of the cranked surface and therefore only a part of the cranked surface is designed to be inclined. In each case, an oblique design with corresponding angles deviating from 90° with respect to the longitudinal axis of the lever is to be understood. The inclined section is preferably inclined with respect to the imaginary boundary surface in such a way that the clearance over its entire height (defined parallel to the shaft axis) is increased by the inclined configuration. A slanting, to In particular, shaft axis inclined transition from the top of the lever to the top of the linkage head is not considered a "sloping section".

In the oblique section, the offset surface preferably assumes an angle α with respect to the longitudinal axis. An upper limit of the angle α is preferably 89°, more preferably 80°, particularly preferably 75°. Additionally or alternatively, a lower limit of the angle α is defined as preferably 30°, more preferably 40°, particularly preferably 45°. Through these angular ranges, a sensible trade-off is made between a stable connection between the lever and linkage head and the largest possible configuration of the free space.

Preferably, it is defined that the inclined portion of the crank surface extends from an acute-angled end to an obtuse-angled end. The acute-angled end of the inclined portion is preferably closer to the interface than the obtuse-angled end. If the inclined section extends over the entire cranked surface, it is preferably provided that the acute-angled end touches the boundary surface.

As already described, there is preferably a cable duct in and/or on the lever. This cable duct preferably opens into the free space at the obtuse-angled end of the inclined section.

The cable channel preferably runs horizontally to the side of the longitudinal axis in the lever or next to the lever. Horizontally on the side means that the cable duct preferably does not run above or below the lever, but instead next to the lever. This ensures that the lever structure is as low as possible.

In addition or as an alternative to the inclined section, the cranked surface can have a convex contact section. The cable can rest against this section or the cable can be bent around this section. In particular, the contact section only comes into contact with the cable when there is a relatively large rotary movement in one of the two directions of rotation. The contact section can be formed by an additional element which is connected to the linkage head and/or the lever and thereby forms a section of the offset surface. However, the contact section can also be formed by an integral part of the lever.

From the free space, the cable runs in the direction of the door operator. In particular, the cable is guided past the side of the rod head. A pivoting member is preferably used for this purpose. This pivoting member is designed for non-rotatable connection with the door operator. As a result, the door operator linkage together with the output shaft rotates relative to this pivoting member. In particular, the pivoting link is positioned radially outside of the rod end. A cable routing, deflected by 90°, preferably takes place via the pivoting member from the free space into the door operator. In this case, the cable can be passed through the pivoting member. Alternatively, the cable can also be connected to the pivoting member, with another cable or other line leading from the pivoting member to the door operator.

Provision is preferably made for the linkage head, and thus also the lever and the output shaft, to be rotatable by at least 135°, preferably by at least 180°, relative to the pivoting member. Corresponding the free space must be large in order to allow the cable a sufficiently large bending radius in the free space with this large angle of rotation.

As described, the pivoting member is preferably located radially outward of the rod end. Furthermore, the radial casing is preferably located radially outside of the pivoting member, so that the pivoting member is arranged between the radial casing and the rod end.

A positive-locking element is preferably located on the side of the rod head facing away from the free space. This form-fitting element enables the non-rotatable connection to the output shaft. In particular, the form-fitting element is a polygon socket that is pushed onto the polygon socket of the output shaft.

The positive-locking element can preferably be detached from the remaining part of the rod head in a non-destructive manner and is therefore exchangeable and/or rotatable. It is preferably provided that the positive-locking element can be fastened to the rod head in different rotational positions relative to the rod head.

The lever and the linkage head can be made in one piece, for example by a bent piece of metal. In this case, the offset is formed, in particular, by a bending edge that is inclined relative to the longitudinal axis.

Alternatively, the lever and the linkage head are two components welded together. The lever particularly preferably overlaps with the linkage head, with one end of the lever forming the offset surface and one end of the linkage head forming the shoulder.

In particular, it is provided that the lever and the linkage head are welded over their entire area in the overlap. In particular, an accumulation of material is positioned between the lever and the linkage head and is resistance welded to form-locking the two overlapping surfaces of the lever and the linkage head.

The invention also includes a door operator assembly. The advantageous configurations presented as part of the door actuator linkage and the dependent claims listed for the door actuator linkage are correspondingly advantageously applied to the door actuator arrangement.

The door operator assembly includes a door operator with an output shaft and the door operator linkage, wherein the linkage head is configured for non-rotatable mounting on the output shaft. The rod head is preferably mounted in a rotationally fixed manner on the output shaft.

The invention also includes a revolving door assembly. The advantageous configurations presented as part of the door actuator linkage and the dependent claims listed for the door actuator linkage are correspondingly advantageously applied to the revolving door arrangement.

The revolving door arrangement comprises the door operator arrangement described above and a door leaf, with the door operator being mounted on the door leaf and the door operator linkage being designed for mounting on the frame or wall, with a shoulder formed by the bend reaching behind the door leaf. The lever thus protrudes from the frame or wall over the upper edge of the door leaf and extends somewhat downwards due to its offset, so as to be connected to the output shaft of the door operator to be able to. The offset creates a shoulder that engages behind the door leaf on the side of the door operator.

A revolving door arrangement 200 with a door operator arrangement 100 including door operator linkage 1 is described in detail below with reference to all figures.

1 shows a revolving door arrangement 200 with a frame 201 and a door leaf 202 rotatably accommodated in the frame 201. The revolving door arrangement 200 also includes the door actuator arrangement 100.

The door operator assembly 100 includes a door operator 101 with an output shaft 102, designed here as a door drive. The output shaft 102 rotates about a shaft axis 103. The door operator 101 is mounted on the door panel 202. Furthermore, the door operator arrangement 100 has the door operator linkage 1 . In the example shown, the door operator linkage 1 comprises a lever 2 which is rotatably connected to a slider 5 . The sliding piece 5 is guided in a sliding rail 4 so that it can move linearly. The slide rail 4 is attached to the frame 201.

The detailed structure of the door operator linkage 1 results in particular from the Figures 2 to 7 .

The lever 2 merges into the rod head 3 with an offset 6 . This offset 6 creates a free space 9. The shaft axis 103 runs through this free space 9, since the free space 9 is located above the output shaft 102.

A bottom of the free space 9 is delimited by the top of the rod head 3 . A lateral delimitation of the free space 9 forms an offset surface 7. This offset surface 7 is created by the offset 6. In the exemplary embodiment shown, the offset surface 7 is formed by an end face of the lever 2 facing the shaft axis 103.

The cranking 6 creates the cranking surface 7 on one side and on the opposite side, which is the bottom side in the example shown Door operator linkage 1 a paragraph 8. As shown in 2 1, the lever 2 overhangs the door leaf 202 and extends downward through the crank 6 with the linkage head 3 to allow connection to the output shaft 102. Paragraph 8 engages behind door leaf 202.

For example show 3 and 5 an imaginary boundary surface 10. This imaginary boundary surface 10 is perpendicular to a longitudinal axis 11 of the lever 2 and parallel to the shaft axis 103. At the same time, the foremost end of the lever 2 or the offset surface 7 defines the position of this imaginary boundary surface 10. Of the boundary surface 10, the Offset surface 7 withdrawn so as to design the free space 9 as large as possible.

In the exemplary embodiment shown, the offset surface 7 is formed with an inclined section 12 at an angle to the longitudinal axis 11 and thereby assumes an angle α of approximately 35°. This inclined section 12 extends from an acute-angled end 15 to an obtuse-angled end 16.

Figures 3 and 4 show a variant in which the offset surface 7 has an inclined section 12 and a contact section 13 . In the construction shown, the contact section 13 is formed by an additional element 14 . This additional element 14 is assigned to the lever 2 . The abutment section 13 can also be formed by an integral part of the lever.

figure 5 shows that the entire cranked surface 7 can also be formed by the inclined section 12, so that the acute-angled end 15 of the inclined section 12 protrudes as far as the imaginary boundary surface 10.

The advantage of the contact section 13 in its convex configuration is apparent when considering the Figures 3 and 4 . These figures show a cable 18 being routed through the free space 9. The door operator linkage 1 can be rotated by up to 180° relative to the door operator 101. Such a twist is in considering the Figures 3 and 4 evident. At the in 4 shown twisting or with an even more far-reaching twisting, the cable 18 comes into contact with the contact section 13 . Due to the concave design of the contact section 13, defined bending with the largest possible radius of the cable 18 is specified.

Figures 3 and 4 illustrate that a cable duct 19 is formed laterally offset to the longitudinal axis 11 next to the lever 2 . The cable 18 runs through this cable duct 19. The cable duct 19 is located inside a lever casing 20.

The cable duct 19 opens into the free space 9 at the obtuse-angled end 16.

Also show Figures 3 and 4 , that the door operator linkage 1 comprises a pivoting member 17 . This pivoting member 17 is to be firmly connected to the door operator 101 and is used to redirect the cable routing from the essentially horizontal cable routing in the free space 9 to a vertical routing in the direction of the door operator 101.

The pivoting member 17 is located radially outside of the rod head 3 and radially inside a radial casing 21. This radial casing 21 surrounds the rod head 3 and delimits the free space 9, in addition to the offset surface 7, laterally.

An upper side of the free space 9 opposite the linkage head 3 can be closed by a free space cladding, not shown.

This free space lining then forms the upper boundary of the free space 9. The top of the lever 2 can also be lined accordingly.

6 illustrates a radial distance 22, measured perpendicularly to the shaft axis 103, from the shaft axis 103 to the outer edge of the rod head 3. This radial distance 22 must be designed correspondingly small, otherwise paragraph 8 (see 2 ) would collide with the door leaf 202. The overlapping area between lever 2 and linkage head 3 is correspondingly limited. 6 shows that an accumulation of material 23 is applied to the rod head 3 . Thereupon the lever 2 and the linkage head 3 overlap and these two elements are welded, in particular areally welded by a resistance welding process.

Figures 5, 6 and 7 show that the rod head 3 has a form-fitting element 24 . This positive-locking element 24 includes a polygon socket for plugging onto the output shaft 102.

7 makes it clear that the form-fitting element 24 can be detached from the remaining part of the rod head 3 without being destroyed. As a result, the positive-locking element 24 can be replaced and/or mounted on the rod head 3 in different rotational positions relative to the rod head 3 .
