Description

The The invention relates to a pivot drive for a goal post swiveling gate leaf a swing gate comprising an electric drive motor and a reduction gear and a bearing the drive motor and the reduction gear, for housing provided inside the goalpost bracket includes. The invention further relates to a swing gate with at least a pivotable about a goalpost pivoting gate and with a housed inside the goal post pivot actuator for the Leaf.

From the DE 10 2004 001 771 A1 the applicant is known a surface-pivoting actuator for a swing gate, which is housed in a mounted on the gate post housing. In some cases, however, the customer prefers invisible mounting of the rotary actuator. This is basically an underfloor mounting of the rotary drive possible, but this requires earthworks that can not be done anywhere.

Next is from the DE 20 2004 010 343 U1 already known a drive post for swing gates, in which a self-locking rotary actuator is integrated. The drive post is there provided with a bottom plate so that it can be pegged onto a foundation, and carries the hinged gate at the goal post. However, this arrangement has the disadvantage that the post not only absorb the weight forces exerted by the swing gate but also the torques introduced by the wind power into the pivot drive and the reaction forces or reaction moments exerted on the pivot drive during pivoting of the gate must be robust. However, this is in contrast to the desire to make the post with low weight and therefore inexpensive aluminum, and is also hampered by the need for a relatively large opening in the post, so that provided for connection to the gate pivot arm not only led out of the post but also over a usual swing angle of at least 120 degrees can be pivoted.

outgoing This is the object of the invention, a rotary actuator and to improve a swing gate of the type mentioned in the introduction, that they make a goalpost from a thin-walled Extruded profile, in particular made of light metal, allow.

These Task is in terms of the swing gate according to the invention thereby solved, that the pivot drive one on a foundation of the goalpost mounted and anchored in the foundation bracket comprises, on which the goal post is attached, including the bracket in the pivot drive according to the invention with facilities for mounting and anchoring on the foundation provided the Torpfostens and is designed so that they Placing the goal post on the foundation from below in its to introduce open lower front end leaves.

The Means for mounting and anchoring the bracket on the Foundation preferably comprise a part formed as part of the holder Base plate, which has a plurality of holes for embedded in the foundation Has anchoring screws.

Of the Invention is based on the idea by the assembly and anchoring the holder of the rotary actuator on the foundation of the goalpost at least by wind forces on the gate in the rotary actuator introduced torques and the pivoting of the gate of this exerted on the rotary actuator reaction moments or Reaction forces over the Bracket directly, i. bypassing the goal post, into the foundation derive, so the goal posts by these moments and forces are not is claimed and therefore without affecting its stability with a lower wall thickness and / or a larger cross section can be produced.

A further reduction of the wall thickness of the Torpfostens and thus a further material and cost savings let yourself reach, if according to a preferred embodiment of the invention also at least a part the weight forces the gate is not in the goalpost but in the holder to be initiated by these preferably at least one laterally from the goalpost protruding out Boom carries, which carries a lower hinge of the gate. In order to avoid putting the jib on the jib Holder hindered, the latter expediently in its adjacent to the door leaf Sidewall a downwardly open recess on which the boom when placing the goal post on the holder receives.

A further preferred embodiment of the invention provides that the holder is housed with the pivot drive immediately above the foundation in the goal post. This not only facilitates the placement of the goal post and the transmission of torques and forces from the holder of the pivot drive in the foundation, but it is also possible, a for pivoting the door leaf on this acting output element of the pivot drive through the provided for the boom in the goal post recess out of the goal post lead out.

According to one preferred embodiment of the invention and patent-based Invention variant is a force acting on the door leaf force transmission element the pivot drive formed by a gear, preferably rotatably mounted on the boom and rotatably connected to the gate is. Alternatively could as a power transmission element but also a chain, a timing belt or a friction wheel use Find.

to Montage of the goal post, this is preferably also on the Fixed bracket, convenient with Help from up above the bracket protruding Threaded rods, which are characterized by receiving bushes welded inside the goalpost to lead and brace with nuts against upper ends of the receiving bushes to let.

The Reduction gear of the rotary actuator preferably comprises a Angled on the electric motor angle reduction gear and a downstream two-stage planetary gear to for a large reduction ratio to care.

According to one Another preferred embodiment of the invention is in the rotary actuator integrated a stop mechanism for limiting the pivoting of the gate, preferably in the area of serving as a power transmission element Gear is arranged so that he after the assembly of the goal post from the outside accessible, If necessary, an adjustment of the angular position of the opening or closed position of the gate to enable.

Further the pivot drive preferably comprises an integrated emergency release mechanism, with the two meshing gears of the reduction gear uncouple, as well as an integrated locking mechanism, with which can block the rotary actuator.

in the The following is the invention with reference to an illustrated in the drawing embodiment explained in more detail. It demonstrate:

1 : A front perspective view of a swing gate with two goal posts and two pivotable with the invention pivot drives leafs;

2 a partially cutaway enlarged perspective view of one of the two goalposts of the swing gate with the associated pivot drive;

3 an enlarged perspective view of the pivot drive;

4 : another enlarged perspective view of the rotary actuator.

This in 1 The Drehtor shown in the drawing 2 consists essentially of two goalposts 4 and two gates 6 , each one with the help of one within the associated goalpost 4 housed quarter turn actuator 8th ( 2 to 4 ) is pivotable between an open position and a closed position.

How best in the 2 . 3 and 4 illustrated, includes the pivot drive 8th for each gate 6 an electric motor 10 with angular reduction gear 12 , one below the electric motor 10 and the angle reducer 12 arranged two-stage planetary gear 14 (not shown in detail) for further speed reduction, the input shaft (not visible) via an upper gear pair 16 . 18 from the angle reducer 12 is driven, and one below the planetary gear 14 arranged lower gear pair 20 . 22 , its output gear 22 in the area of a lowermost hinge 24 of the gate 6 is arranged and the power transmission element for transmitting the torque of the rotary actuator 8th on a rigid with the gate 6 connectable swivel arm 26 and thus on the gate 6 forms.

At the electric motor 10 It is a common for door drives 24 volt DC motor whose angle reduction gear 12 designed as a worm gear and therefore self-locking. The angular reduction gearbox 12 has a downwardly projecting output shaft 28 on, the rotation with the gear 16 of the upper gear pair 16 . 18 connected is. The gear 16 is meshing with the gear 18 that is via the input shaft of the first upper stage of the planetary gear 14 rotatably connected to the sun gear of this planetary gear stage, while their planet carrier arranged underneath the second stage of the planetary gear 14 drives. This second stage has the same construction and also the same reduction ratio as the first stage, but its output shaft connected to the planetary carrier and projecting downwardly is non-rotatable with the gear 20 connected, which in turn meshed with the gear 22 stands.

The angular reduction gearbox 12 , the planetary gear 14 and the two gear pairs 16 . 18 ; 20 . 22 serve to increase the speed of the electric motors 10 of 60 rpm with a reduction ratio of 1:48 on the gate 6 so that it can be swiveled 90 degrees in about 14 seconds.

In addition to the electric motor 10 , the angle reducer 12 , the planetary gear 14 and the two gear pairs 16 . 18 ; 20 . 22 includes the rotary actuator 8th further an integrated stop mechanism 30 ( 3 ) for limiting the pivoting movement of the door leaf 6 in the open and closed position, a likewise integrated emergency release mechanism 32 with which the gear 18 from meshing with the gear 16 can be disengaged, in case of interruption of the power supply to the rotary actuator 8th or another malfunction a manual pivoting of the otherwise blocked gate 6 to enable. The rotary actuator 8th also includes an integrated locking mechanism 34 ( 3 ), with which the associated gate wing 6 can lock in the open and closed position and discrete pivot positions arranged therebetween, inter alia, an unauthorized opening of the door leaf 6 to prevent by pressing.

The entire quarter turn actuator 8th is on a bracket 36 inside the respective goal post 4 housed on a concrete foundation 38 ( 1 ) of the goalpost 4 supported. This ensures that any, for example, by the wind pressure on the gate 6 , in the locking mechanism 34 of the rotary actuator 8th introduced torques, any when pivoting the door leaf 6 on the rotary actuator 8th acting reaction moments, as well as those of the gate 6 on the lower hinge 24 applied weight directly into the concrete foundation 38 to get redirected. By this measure, the moments and forces largely relieved goal posts 4 be produced by extrusion of a relatively thin-walled light metal profile with a large cross-section, for example 200 × 200 mm, whereby he next to the accommodation of the pivot drive 8th within its lower front end also accommodating other components, such as an integrated electronic drive control, terminal strips for power and control cables, an intercom, a lighting system, a mailbox or the like (not shown) allowed.

The holder 36 consists essentially of a base plate 40 , one below the lower gear pair 20 . 22 arranged on the base plate 40 supported support plate 42 that the entire quarter turn actuator 8th carries, one between the lower gear pair 20 . 22 and the planetary gear 14 arranged intermediate plate 44 , as well as one above the planetary gear 14 arranged mounting plate 46 who are rigid with the plates 42 and 44 is connected and for mounting the electric motor 10 with the angle reducer 12 , as well as the emergency release mechanism 32 and the locking mechanism 34 serves.

The base plate 40 is in the concrete foundation 38 by four bolts 48 anchored whose bent lower ends are embedded in the concrete and whose upper, holes in the base plate 40 penetrating threaded ends through nuts 50 against the top of the base plate 40 be tense. About the base plate 40 stand four parallel threaded rods 52 through holes 54 in the support plate 42 above over, between the base plate 40 and the support plate 42 of spacers 56 are surrounded. The over the support plate 42 projecting upper end pieces of the threaded rods 52 be through recording sockets 58 ( 2 ), which are inside the goal post 4 welded in the four corners of the light metal profile near the lower end face, and can then through an access opening (not shown) in one of the side walls of the Torpfostens 4 through with nuts 60 against the upper ends of the receiving bushes 58 be strained to the goalpost 4 on the bracket 36 to fix.

The intermediate plate 44 has a cantilever jib 62 on top of a corresponding cantilever (not visible) of the support plate 42 is arranged. The outriggers 62 extend one above the other at a vertical distance through a recess in the gate 6 facing side wall 80 of the goalpost 6 from within it, forming together with one in pivot bearings of the two arms 62 rotatably mounted pivot pin 66 the lower hinge 24 of the gate 6 , The upper hinge 68 of the gate 6 is at the desired height at the gate 6 facing side wall 80 of the goalpost 4 attached and consists essentially of a with a fixing screw 70 at the goalpost 4 attached pivot bearing 72 and one from below into the pivot bearing 72 inserted pivot pin 74 which is above one with the top of the gate 6 connectable short swivel arm 76 survives as best in 2 shown.

The recess in the side wall 80 of the goalpost 4 is to the lower front end of the goalpost 4 towards the edge, leaving the goalpost 4 after mounting the bracket 36 and the rotary actuator 8th on the foundation 38 put on and over the threaded rods 52 with the bracket 36 can be bolted before last the gate 6 between the swivel arms 26 . 76 the lower and the upper hinge 24 . 68 is inserted and secured by tightening it.

Between the two booms 62 . 64 the support plate 42 and the intermediate plate 44 is the gear 22 used, via a polygon on the upper front end of the pivot pin 66 rotatably and positively connected with this, so that the pivot pin 74 fixed swivel arm 26 together with the gate 6 is pivoted when the rotary actuator 8th by power supply to the electric motor 10 is put into operation.

The stop mechanism 30 to limit the pivoting movement of the door leaf 6 consists essentially of one in the top of the gear 22 recessed annular groove 84 ( 3 ) with a groove bottom diverging cross-section and two in the annular groove 84 inserted sliding blocks 86 . 88 , which have a smaller width compared to the groove cross section but the same height and in each case with three from top to bottom through threaded holes 90 are provided. The nuts 86 . 88 can be in the area of an extension (not shown) from the top into the groove 84 inserted inside the groove 84 infinitely shifted to a desired angular position and then in this angular position with the gear 22 be braced by going from the top into the holes 90 Tighten the clamping screws until their lower ends are pressed against the groove base. The nuts 86 . 88 then stand so far on the top of the gear on that their opposite end faces during pivoting of the door leaf in the open and closed position against a respective opposite stop surface 92 the intermediate plate 44 strikes. The arrangement of the sliding blocks 86 . 88 in the top of the out through the recess out of the goalpost 4 protruding gear 22 ensures that the stop mechanism 30 after installation of the goal post 4 accessible from the outside, which makes it considerably easier, the angular position of the gate 6 to be adjusted in the open or closed position. The using the stop mechanism 30 maximum adjustable swivel angle of each gate is 130 degrees, but if necessary by waiving the stop mechanism 30 be increased to 180 degrees by the sliding blocks 86 . 88 out of the groove 84 be removed.

The emergency release mechanism 32 includes a rotationally fixed to the input shaft of the upper stage of the planetary gear 14 connected disc 100 ( 4 ) having a plurality of axially upwardly projecting bolts (not visible), which from below into complementary axial receiving bores of the gear 18 intervention. The gear 18 can with a lever mechanism 102 be lifted off the disc to get it out of engagement with the gear 16 disengage, without it being decoupled from the input shaft of the upper planetary gear stage. The lever mechanism 102 includes a release lever 104 passing through the access opening of the goalpost 4 through in relation to the mounting plate 46 manually out of the 3 and 4 shown locking position can be pivoted into a corresponding unlocking position, and a locking lever 106 that the release lever 102 locked up to a manual release of the emergency release in this position. The arrangement of the emergency release mechanism 32 between the self-locking angle reducer 12 and the planetary gear 14 it allows the unlocked gate 4 pivot with very little effort. To signal the power steering the emergency release, thereby starting the electric motor 10 to prevent is next to the release lever 102 a microswitch connected to the controller via cable 108 attached when pivoting the lever 104 responds.

The above the gear 18 arranged locking mechanism 34 ( 3 ) includes a locking bolt 110 standing in a rigid on the mounting plate 46 attached guide 112 is guided vertically movable. The locking bolt 110 is caused by an electric lifting magnet acting on it 114 during operation of the rotary actuator 8th against the force of a locking spring out of engagement with one of a plurality of holes on a rotationally fixed to the gear 18 connected, arranged on the upper side locking disc 116 ( 4 ) is lifted and pushed by the locking spring down into one of the holes when the solenoid 114 when reaching the open or closed position of the door leaf 4 de-energized or the power supply to the rotary actuator 8th disruption is interrupted, causing the gate 4 is mechanically locked in the currently occupied position.

How best in 2 is shown on the open upper front end of the light metal profile of the goalpost 4 an adapter 118 attached, which allows the attachment of caps, which are intended for smaller Torpfostenquerschnitte. The adapter made of plastic 118 is with several stages 120 . 122 provided, the cross-sectional dimensions of the standardized opening cross-sections of receiving openings on the undersides of these caps fit and optionally be sawed off in part, if these receiving openings are very flat.
