Definitions

  • Folding gates that open upwards are widely used as garage doors in Northern Europe, for example.
  • Such a folding door consists, for example, of two segments which are connected to one another in an articulated manner and the upper segment is pivotably mounted in the vicinity of the upper edge.
  • the lower segment is guided in a lateral guide rail by means of a roller which is located near the lower edge of the lower segment.
  • the lower segment is raised, whereby the articulated connection between the door segments moves into the interior of the building and the role of the lower segment in the side guide rail slides up until the two segments lie parallel to each other approximately horizontally at the level of the upper edge the door opening.
  • This opening process is generally supported by a gas pressure damper, which is arranged, for example, between the upper door segment and a point fixed to the building.
  • the invention now relates to an electrical, retrofittable drive for such gates.
  • a pulling element such as a chain or a toothed element is used for the purpose of an electric drive on the ceiling of the garage, which is connected to the door leaf by means of a connecting element and pulls it backwards and thus into the open position.
  • a drive would, however, be unsuitable for a segment gate opening upwards, since its segments essentially move upwards during the opening process and much less into the interior of the building than one-piece swing gates.
  • the purpose of the present invention is to enable an emergency actuation of the gate in the event of a power failure or a defect in the motor by manual actuation in such a generic drive.
  • Sensitive parts of the drive such as the control in the form of an electrical circuit, electromechanical limit switches and exposed gear parts, are housed inside a closed drive unit, thereby protecting them from damage during assembly and from contamination and the resulting malfunctions during operation. Since this drive unit must be connected to the building in a rotationally fixed manner according to the present invention, the drive unit must be built very flat at least in one dimension, since, for example, often little space is available to the side of the door opening.
  • This drive unit includes a motor-gear unit, the transformer required for this, a circuit board with the appropriate control for the entire unit and the necessary additional translation of the motor output shaft to a dimension that is necessary for driving the entire drive unit.
  • the output of the drive unit is a socket, which is arranged parallel to the narrow sides of the drive unit and has an out-of-round or polygonal contour on at least one of its end faces, to which a transmission element can be connected in a form-fitting manner to decrease the rotational movement emitted.
  • a lever is preferably used, which is connected at one end to the socket in a rotationally fixed manner and extends essentially parallel to the upper gate segment.
  • the other end of the lever is connected to the lower edge of the upper gate segment by a pin attached to the inside of the upper gate segment running in an elongated hole of the lever.
  • the lever described will preferably be arranged approximately in the middle of the door width, in order not to allow the door to jam in the guide rails due to the one-sided loading, particularly in the case of wide doors.
  • the socket to be connected to the lever must be extended to the center of the door, which can also be done by means of an extension rod that extends over the entire door width and is supported on both sides.
  • an extension rod that extends over the entire door width and is supported on both sides.
  • not only one but several levers can be arranged at different points on the door, for example on both side edges, with the extension rod become what is recommended with increasing width and weight of the gate.
  • a rotation of the socket serving as the output of the drive unit is thus only required of approximately 90 °.
  • the gate to be moved can be moved from a defective or de-energized drive unit by moving the socket against Force of the spring can be uncoupled.
  • the bush has a circumferential groove on its outer periphery, in which a fork, which is pivotally mounted in the housing, engages in such a way that by actuating the fork the bushing against the force of the spring out of connection with the gearwheel brought.
  • the gate can be opened manually despite the stuck and non-rotating motor.
  • the electric motor Since the electric motor has a larger dimension along its longitudinal axis than is desired in the drive unit between the lower part and cover, that is to say the narrow side, the electric motor can only be accommodated on the lower part. Since the axis of the bushing used as the output is perpendicular or skewed, a one-time deflection of 90 ° is required for the rotary movement.
  • a planetary gear is therefore additionally installed on the output shaft of the motor-gear unit for further reduction, which meshes with a comparatively large gearwheel, which is detachably connected coaxially and in a rotationally fixed manner to the socket. Because of this rotationally fixed coupling, this large gear wheel can also only rotate by 90 ° between the open and the closed position.
  • the axis of the planetary gear is parallel to the axis of the socket and thus parallel to the narrow sides of the drive unit and perpendicular to the lower part and cover of the housing of the drive unit.
  • the planetary gear Viewed from the output shaft emerging from the front of the gear unit, the planetary gear consists of two levels: In the first level, the motor output shaft rotates several planet gears via an attached pinion, which roll on the outside in an internally toothed ring. At the center of the planet gears are axes rotatably mounted, which extend into the second plane of the planetary gear, which consists of a central gear, so that this central gear is rotatably connected to the centers of the planet gears.
  • the central wheel is hollow and is mounted in this central bore by means of plain bearings on the outer diameter of a flange which is screwed onto the cover on the outside and projects into the interior of the housing. This central wheel is provided on the outside with a toothing which meshes with the toothing on the circumference of the large gearwheel lying in the same plane, which represents the last reduction stage.
  • the large gear runs on an outer circumference of the socket described, with which it is rotatably connected via dowel pins.
  • the socket itself is slidably supported at its ends on the outer diameter relative to the inner diameter of a respective bearing flange, which is screwed onto the cover or the lower housing part of the drive unit from the outside and projects into the interior of the housing through a corresponding recess.
  • the lower part of the housing and the cover consist of metal plates with preferably bent edges, which are screwed together using spacers. Inside the bent edges, side walls, for example made of transparent plastic, can be inserted before screwing, so that the function of the drive unit can be observed and checked without opening it after attaching a lighting source within the drive unit.
  • the dowel pins connecting the bushing and the large gearwheel are held axially firmly in one of the two parts by means of a press fit or screw connection, but axially displaceable in the other part.
  • the bushing has a shoulder between which and the large gear Opposite outer wall of the housing, the compression spring is arranged so that the bush is held in contact with the gear.
  • Limit switches are still required for the motorized drive of the gate.
  • the limit switches which are intended to cause the open or closed position to be reached and thus to switch off the motor, can indeed be arranged directly on the gate, so that the reaching of the open and closed position of the gate is then indicated immediately.
  • any lever that projects radially away from the large gearwheel in the direction of the actuating element of the associated limit switch can serve as the trigger element here.
  • a small angle element is preferably fastened on the large gearwheel, through which from the gear striving leg there is a threaded hole through which a threaded bolt can be screwed and fixed by means of a nut.
  • the protrusion of the threaded bolt over the front edge of the profile is infinitely adjustable, which is used to fine-tune the triggering of the limit switches.
  • Purchased parts with the protruding tongue are used as the actuating element as limit switches, which are screwed onto the housing so that the tongue protrudes into the area of the threaded bolt on the large gear.
  • the final shutdown is accomplished by simple purchased parts, which has the desired consequence of low production costs for the entire drive unit.
  • Fig. 1 the building can first be partially recognized, consisting of the ceiling 1 and the lintel 2, and the door cavity 46 in which the door is arranged.
  • the gate consists of the upper gate segment 5 and the lower gate segment 6, which are rotatably connected to one another via a joint 4. In the illustration in FIG. 1, the gate is in the fully open position, while a position that is only partially open is shown in broken lines.
  • the upper door segment is mounted near its upper edge along an axis of rotation 3 at two bearing points, that is to say on each side of the door, in the wall of the building, while the lower segment is perpendicular to the side of the door cavity via a roller 14 which is attached to the side in each case extending guide rail 13 is guided.
  • the opening and holding of the door in the open position is supported by gas pressure dampers 8, which are connected on the one hand to the upper door segment 5 and on the other hand to a hinge bracket 7 fixed to the building next to the door cavity.
  • Fig. 1 also shows the arrangement of a drive unit 11 inside the building next to the door cavity.
  • the drive unit 11 is mounted at such a height that the square 44 of a socket 30 of the drive unit shown lies above the upper door segment 5 which is in the open, ie horizontal position. Because of this position, the socket can be connected in a rotationally fixed manner via the square 44 or another non-positive or positive connection to the socket with a coaxial extension rod which extends above the gate over the entire width of the gate, so that several extend from this extension rod Make a connection to the upper gate segment is possible. This will preferably be done on both sides of the gate if the gates are large, wide and therefore heavy.
  • a single connection between the square 44 and the upper gate segment 5 is sufficient, which can be arranged, for example, approximately in the middle of the width of the gate.
  • connection consists of a lever arm 9 which is rotatably connected on one side to the square 44 and then to the socket 30 and parallel to the rear of the upper Gate segment 5 runs.
  • This lever 9 is machined in the longitudinal direction of the lever 9 near its other end.
  • a pin 47 protrudes into this elongated hole, which runs horizontally and parallel to the rear of the upper door segment 5 and is firmly connected to the latter via an angle 48. If the lever 9 is now pivoted from its horizontal position around the square 44 by approximately 90 ° into a downwardly projecting, vertical position, this also brings the upper gate segment 5 and thus the entire gate into its vertical, closed position.
  • Fig. 2 shows a plan view of an open drive unit 11, that is, with the cover 16 removed, so that it can be seen how the individual units are arranged on the lower part 15.
  • Fig. 2 shows a plan view of the lower part 15 of the drive unit, in which some elements are only shown symbolically, such as the circuit board 18, on which the control for the entire electrical drive unit is housed and which is by means of electrical lines from a manually operated switch or can be controlled by a wireless hand transmitter, if it contains a corresponding recipient.
  • the transformer 19 which converts the usually only available high-voltage alternating current into direct current for the motor-transmission unit 20.
  • the motor-transmission unit 20 is arranged on the lower part 15 such that the longitudinal axis of the motor runs parallel to the lower part 15 and the axis of the output of the unit is perpendicular thereto, that is to say parallel to the narrow side walls 50 shown on two sides in FIG. 2 As a result, the axial direction of the output of the motor-gear unit is already parallel to the axial direction of the socket 30 serving as the output of the entire drive unit 11 with the inner square 44.
  • This bushing 30 is not driven directly by the output shaft of the motor-gear unit 20, the gear part of which advantageously has a worm gear that is already strongly reducing, but via a further reduction 21, as can best be seen in FIG. 3.
  • the output shaft of the motor-gear unit 20, which is screwed onto the lower part 15, is extended to such an extent that it extends through the opposite cover 16 and is additionally mounted there via a slide bearing bush in a bearing bush 27 which is on the outside of the cover 16 is screwed on and extends somewhat through a corresponding recess in the cover into the interior of the housing in order to offer a sufficient axial bearing length on its inside diameter and on the outside diameter.
  • the protruding motor output shaft is toothed on the outside and serves as the central pinion 22 of a planetary gear stage, and meshes with a plurality of planet gears 23, which roll outside in a comprehensive, internally toothed outer ring 24.
  • These planet gears 23 each have dowel pins 25 as coaxial axes, which extend in the axial direction away from the motor gear unit out of these planet gears and in the next axial stage - starting from the motor gear unit 20 - protrude into corresponding recesses in a central gear 26.
  • This central wheel which is mounted coaxially on the outer circumference of the bearing bush 27 and thus coaxially with the motor output shaft, is thus located between the planetary gear stage and the cover 16, as a result of which the space between the motor gear unit 20 and the cover 16 in the axial direction is approximately complete is filled.
  • This externally toothed central gear 26 is rotated via the connection to the planet gears 23 with their rotation and meshes with its external toothing with the large gear 28 running in the same plane, which is normally connected in a rotationally fixed manner to the socket 30 serving as the output of the drive unit 11 is.
  • This large gear 28 is, like the central gear 26, parallel to and immediately adjacent to the cover 16 and is already held in this axial position by the fact that an axial offset in the direction opposite the cover is limited by the planetary gear stage, which one has a larger outer diameter than the underlying central gear 26 which meshes with the large gear 28 and thus partially projects beyond the large gear 28.
  • the dowel pins 25 between the planetary gear stage and the central gear 26 which is coaxial in the next stage must therefore either be in the central gear 26 Have a press fit and slide bearings in the planet gears 23 or vice versa.
  • the planetary gear stage is held between the large gear 28 and the tarpaulin end surface of the motor gear unit 20 from which the output shaft protrudes.
  • the large gear 28 is not directly supported, but sits coaxially on an outer circumference of the bush 30, and is connected to this in a rotationally fixed manner via two pairs of pins 29. Since this connection is designed to be detachable, the dowel pins 29 are press-fit either in the socket 30 or in the large gearwheel 28, while they have a clearance fit in the other part and are therefore axially displaceable.
  • the bushing 30 itself is slidably supported on both sides, that is to say in the lower part 15 and in the cover 16, in a bearing flange 34, which is screwed onto the outside of the lower part 15 or the cover and extends somewhat into the interior of the housing through a corresponding recess , so that there is a sufficient axial bearing width for the bush 30.
  • Plain bearing bushes 42 are arranged between the bush 30 and the bearing flange 34.
  • the drive unit 11 is thus approximately as flat as the distance between the lower part 15 and the cover 16, since beyond this distance only screw heads protrude, by means of which, for example, the motor-gear unit 20 is screwed to the lower part 15 or through the lower part 15 and cover 16 are screwed through with a spacer 41 to connect them.
  • the bearing flanges 34 and the bearing bush 27 do not protrude further beyond the outer edges of the lower part 15 and cover 16 than the heads of these Screws.
  • the bushing 30 closes on the lower part with the outer surface of the bearing flange 34, while on the side of the cover 16 it projects a few millimeters beyond the outer surface of the bearing flange 34.
  • the bush 30 by means of a spring 33 loaded under pressure in the form of a spiral spring which is arranged between the flange 34 of the lower part 15 and a corresponding shoulder of the bush 30, normally against the large gear 28 and thus the Lid 16 is pressed.
  • the bushing 30 can be axially displaced against the force of this spring to such an extent that the hardened dowel pins either no longer hold a positive connection either with the bushing 30 or with the large gearwheel 28.
  • the gate to be driven which is generally connected to the socket 30 and its inner square 44 in a form-fitting manner, is separated from the motor-gear unit 20, so that the gate can move freely when it fails and can be opened by hand.
  • Such an axial displacement of the bush 30 against the force of the spring 33 can be accomplished in that a fork, not shown in FIG. 3, engages in a circumferential, radial groove 31 of the bush 30, which is located between the shoulder 32 and the large gear 28 .
  • a fork 43 is pivotable about an axis which is perpendicular or skewed to the longitudinal axis of the bush 30, so that by pivoting the fork about its axis, which can be done by an operator, for example by means of a cable, the bush 30 is axially displaced and so that can be disengaged from the large gear 28 to open the gate by hand.
  • the bushing 30 in the normal position must protrude somewhat beyond the edge of this bearing flange.
  • the socket 30 is hollow, so that the inner square 44 extends through the entire length of the socket. This has the advantage that - depending on the possibility of mounting the drive unit 11 - a corresponding outer square can optionally be inserted in both sides of the inner square 44, which is also positively and thus non-rotatably connected to one end of the lever 9 of FIG. 1.
  • the mounting options of the drive unit 11 on a door to be driven are thereby made considerably easier.
  • Fig. 3 also shows the bent edges 17 of the lower part 15 and the lid 16, which are kept at a distance from each other by the spacer 41, in whose end faces the fastening screws reaching through the lower part 15 or lid are screwed.
  • the entire drive unit is disassembled by removing the cover 16, as a result of which all the gears can be pulled off the shafts carrying them in succession and the sleeve 30 and the spring 33 can also be removed.
  • a complete disassembly and replacement of individual functional parts is thus possible by loosening only a few screws, without having to loosen the press seats or disconnect other complex connections.
  • the side surfaces 49 of the housing between the lower part 15 and the cover 16 are closed by interposed side walls 50, which - depending on the mounting position of the drive unit - can be transparent plastic, at least on the underside. In this way, a function check is possible at any time without dismantling the drive unit by arranging a light source within the housing.
  • Fig. 2 shows in addition to the assignment of the large gear 28 to the motor-gear unit 20 and the downstream planetary gear stage, the arrangement of the limit switches 35, which serve to automatically switch off the drive when the gate is the fully closed or fully open position has reached.
  • the limit switches 35 are arranged outside the circumference of the large gear 28 so that their tongues 40 to be triggered extend into the circumferential area of the large gear 28, but axially offset from this.
  • actuation elements are in turn firmly connected to the large gear 28, which trigger them when a rotary position is reached in accordance with the position of the tongue. If, on the other hand, the large gearwheel 28 had to go through several revolutions during operation of the gate, the arrangement of the limit switches would be considerably more complicated, since these should only be actuated with a certain number of revolutions.
  • an angle 36 is fastened on the surface of the gear 28 facing the lower part 15 at a distance of approximately 90 °, the leg of the gear 28 which struts from the gear has a continuous threaded hole through which a screw 37 is screwed and in a specific rotational position is determined by means of a nut 38.
  • the free end face of the screw 37 actuates one of the tongues 40 of the limit switches 38, which are offset by approximately 180 °.
  • the fine adjustment of the limit switches is done by screwing the screw 37 into the threaded bore so far until the screw protrudes over the leg of the angle by the desired amount.
  • the drive according to the invention creates an automatic drive that can be retrofitted at any time for the described gate type, which additionally contains many individual parts that are available at any time as purchased parts and, furthermore, is prone to failure and easy to maintain due to the simple construction of the components and can be repaired in the event of a defect .
