Definitions

  • the present invention relates to an articulated arm drive, in particular for a swing gate, according to the preamble of claim 1.
  • swing gate drives which move the gate with the help of an articulated arm.
  • Articulated arm drives due to their design - require an additional working space on the side facing away from the gate when the door position is open for the articulation of the rotating arms (elbows). If there is an obstacle next to the post, z. B. a wall or the property boundary, such articulated arm drives can not be used.
  • FIG. 1 an example known from the prior art for such an articulated arm drive is shown.
  • the gate 2 can be pivoted through 90 ° about a pivot point 3 attached to a fixed post 1 by means of the articulated arm drive.
  • the articulated arm which is driven by a drive unit 12, consists of two arms 32, 34 which are rotatably connected to one another by a rotary joint 36.
  • the arm 34 on the door side is articulated on the gate via a fitting 39, while the arm 32 on the drive side is connected to an output shaft 14 of the drive unit 12.
  • the gate is shown in a fully (90 °) open position.
  • the swivel joint 36 of the articulated arm moves to the side facing away from the gate or into the interior during the opening movement and therefore requires a certain working space in order not to collide with an obstacle (for example a wall).
  • the first arm 32 executes a rotary movement of more than 90 °.
  • Articulated arm drives are also known in which the second arm 34 articulated on the gate 2 is designed to be relatively short or adjustable in length, so that the first arm 32 fastened to the drive 12 for opening the gate 2 only has a rotary movement of approximately 90 ° executes. In the open position of the gate 2, the two articulated arms 32, 34 are then approximately parallel (see Figure 2 ). This has the advantage that no additional work space is required in confined spaces.
  • the approximately parallel position of the rotary arms 32, 34 also has disadvantages.
  • the gate 2 is not held stable by the drive 12 in its open position, since the rotating arms 32, 34 are almost in a dead position and can oppose little force from a pivoting movement of the gate 2.
  • the drive 12 must exert a very high force when the gate 2 is closed, since the Leverage ratios are correspondingly unfavorable due to the approximately parallel rotating arms 32, 34.
  • an articulated arm drive which comprises a drive unit with an output shaft and an articulated arm, the articulated arm having a first and a second articulated arm member which are rotatably connected to one another by means of a first swivel joint.
  • the first articulated arm member is connected or connectable to a fixed first pivot point at the end facing away from the first swivel joint.
  • the second articulated arm member can be rotatably connected to a gate, in particular a revolving gate, at the end facing away from the first pivot joint.
  • the end of the first articulated arm member facing away from the first swivel joint is not connected to the output shaft and that the driven shaft is connected to one of the articulated arm members via a coupling element.
  • the end of the first articulated arm member facing away from the first swivel joint can, for example, be fastened to a post, a frame, a wall or another fixed part, for example by means of a fitting.
  • the arrangement according to the invention ensures that the gate can be opened without individual links of the articulated mechanism requiring additional work space in the area facing away from the gate or in the interior of the space which can be closed by the gate.
  • This mechanism is particularly well suited for tight installation situations.
  • the articulated arm is held stably and securely by the coupling arm even when the articulated arm members are in an approximately parallel position.
  • the coupling arm is rotatably connected to one of the articulated arm members, that is to say the coupling arm is articulated at one pivot point on one of the transmission arm members.
  • the coupling arm is rotatably connected to the first articulated arm member, that is to say the coupling arm is articulated at a pivot point on the first transmission arm member.
  • the coupling arm comprises a first and a second coupling arm member, which are rotatably connected to one another by means of a second swivel joint, the first coupling arm member being connected to the output shaft, in particular rotationally rigid, at the end remote from the second swivel joint, and wherein the second coupling arm member at the end facing away from the second pivot joint is rotatably connected to an articulated arm member at a second pivot point.
  • the coupling arm is designed as an articulated arm, in particular as a double joint, which results in a particularly space-saving, stable construction which is advantageous with regard to the force to be exerted by the drive unit.
  • the articulated arm drive completely reaches an open position in which a gate connected to the second articulated arm member is open, and has a closed position in which a gate connected to the second articulated arm member is completely closed, the coupling arm and the articulated arm being designed and connected to one another in such a way that the coupling arm members in the open position form an acute angle and in the closed position an obtuse angle Take up angles to each other at the second swivel joint.
  • the door is thus held securely in both end positions due to the position of the coupling arm members.
  • the coupling arm links are almost straight (obtuse angle close but less than 180 °), when the gate is open they are almost parallel (acute angle close but greater than 0 °).
  • the gate movement is slowed down to the two end positions (0 ° and 180 °) with a favorable arrangement of the coupling arm links, since the coupling arm links approach their corresponding dead positions, which protects the mechanics of the entire articulated arm drive and the gate.
  • the rotational movement of the first coupling arm member is faster, preferably almost twice as fast, as the rotational movement of the first articulated arm member.
  • a rotary movement of the output shaft or of the first coupling arm member by approximately 180 ° results in a gate opening of approximately 90 °, which means that even relatively wide and heavy gates can be moved safely.
  • first and second coupling arm members are shorter than the first articulated arm member, preferably shorter than the first and second articulated arm members. This results in further space and weight savings.
  • first and second coupling arm members never assume a dead position.
  • the first coupling arm member moves in an angle of rotation range of less than 180 °.
  • the angle between The two coupling arm links on the second swivel joint therefore do not reach 0 ° or 180 ° in the two end positions (opening and closing position of the articulated arm drive). Because the dead positions (toggle lever action) of the coupling arm links are deliberately not reached, good power cut-off and stability can be guaranteed.
  • the coupling arm and the articulated arm are designed and connected to one another in such a way that the articulated arm members form an acute angle to one another in the open position and an obtuse angle to one another at the first swivel joint in the closed position.
  • first and second articulated arm members never assume a dead position.
  • this has the advantage that good power cut-off and stability can be ensured by avoiding dead positions (toggle lever action).
  • the respective dead positions are advantageously avoided both in the coupling arm members and in the articulated arm members.
  • the length of the first articulated arm member and / or the second articulated arm member is adjustable. This allows the articulated arm drive to be quickly and easily optimally adapted to different installation situations. It can be provided that the first articulated arm member and / or the second articulated arm member is designed as a telescopic rod or telescopic cylinder. The length can be adjusted manually or automatically.
  • the drive unit comprises a drive housing, the fixed first pivot point being arranged on or in the drive housing. This makes it possible to avoid the installation of an additional fitting on which the end of the first articulated arm member facing away from the first swivel joint is articulated.
  • FIGs 3 and 4 show an embodiment of the articulated arm drive 10 according to the invention in the two end positions of the gate 2 operable by it, namely in the closed position in which the gate 2 is completely closed ( Figure 3 ) and in the open position in which gate 2 is fully open ( Figure 4 ).
  • the articulated arm drive 10 allows the gate 2 to be rotated / opened by 90 ° in this exemplary embodiment.
  • the hinged gate 2 which can be moved by means of the articulated arm drive 10, is rotatably mounted on a stationary pivot point 3.
  • the articulated arm drive 10 comprises an articulated arm 30 which has a first articulated arm member 32 and a second articulated arm member 34 which are rotatably connected to one another at their ends by means of a first swivel joint 36.
  • the second articulated arm member 34 is shorter than the first articulated arm member 32.
  • the other end of the second articulated arm member 34 is articulated on the gate 2 via a door-side fitting 39.
  • the other end of the first articulated arm member 32 facing away from the first swivel joint 36 is now, in contrast to drives known from the prior art, not connected to a drive unit, but is articulated to a stationary frame 1 via a fixed frame-side fitting 38.
  • the frame 1 can be, for example, a goal post or a wall.
  • the frame 1, the two articulated arm members 32, 34 and the gate 2 form a quadrangle, the first articulated arm member 32 acting as a rocker and the second articulated arm member 34 as a coupling.
  • the first articulated arm member 32 of the articulated arm 30 is driven via a coupling arm 40, which is designed as a two-stroke.
  • the coupling arm 40 has a first coupling arm member 42 and a second coupling arm member 44, which are rotatably connected to one another at their ends by means of a second swivel joint 46.
  • the first coupling arm member 42 functions as a crank and is connected at its end, which faces away from the second swivel joint 46, to the output shaft 14 of a drive unit 12 of the articulated arm drive 10.
  • the second coupling arm member 44 functions as a coupling and is articulated with its end facing away from the second swivel joint 46 via a pivot point 37 on the first articulated arm member 32.
  • the pivot point 37 is closer to the frame-side end of the first articulated arm member 32 than to the first swivel joint 36.
  • the coupling arm members 42, 44 are shorter than the articulated arm members 32, 34.
  • the inventive design of the articulated arm drive 10 slows the door movement to both end positions, since the coupling arm members 42, 44 approach their corresponding dead positions (but, as already explained, they do not quite reach them). This protects the mechanics of the articulated arm drive 10 (drive, joints, gate, etc.).
  • the gear members 32, 34, 42, 44 of the articulated arm drive 10 move closer to the gate 2 in comparison to conventional articulated arm drives and therefore protrude less far into the free space. This applies in particular when the gate 2 is open (open position), as a result of which the articulated arm drive 10 according to the invention is eminently suitable for narrow installation situations.
  • the articulated arm 30 is always kept stable by the coupling arm 40, in particular in the end positions. Since the coupling arm 40 always has a certain angle to the driven first articulated arm member 32, good and stable force relationships prevail at all times, in particular in the end positions.
