Definitions

  • the invention relates to a drive for opening and / or closing a movable leaf of a door or a window and a method for operating this drive.
  • a drive for opening and / or closing a movable leaf of a door or a window is known.
  • the drive has an output shaft which is operatively connected to the wing.
  • the drive has a spring device which acts on the wing in the closing direction.
  • a locking device that can be switched on and off locks the pretensioned spring device in the switched-on position.
  • the spring device is effective in emergency operating states, for example in the event of fire and / or in the event of failure of the electrical power supply, in that the locking device preferably switches off automatically, and then ensures that the sash closes securely.
  • the invention is based on the object of optimizing a generic drive with regard to its operating behavior.
  • the locking device is designed in such a way that the spring device becomes effective once the wing has reached a predetermined opening angle.
  • the opening movement no longer has to be slowed down by the drive motor alone.
  • the closing movement is supported by the spring device, which partially relaxes up to the predetermined opening angle, whereby the energy consumption of the drive motor is reduced.
  • the adjustable opening angle of the sash from which the spring device becomes effective is not equal to the fully closed or open position.
  • the locking device has at least one spring piston, which divides a cylinder into at least two pressure chambers in a liquid-tight manner, the pressure chambers being connected to one another via at least one hydraulic line.
  • the locking device can have at least one electrically switchable shut-off valve which is arranged in the hydraulic line.
  • the predetermined opening angle can be optimized by appropriate control of the shut-off valve, for example in the event of a changing operating behavior of the drive and / or changing external influencing variables.
  • the locking device can have at least one damping valve which is arranged in the hydraulic line. Instead of the damping valve or in addition, a fixed throttle can be provided, or a narrowed line cross-section. This dampens the movement of the spring piston when it is unlocked, which prevents the spring piston or a component that is actively connected to it strikes hard against a drive component that is actively connected to the drive motor.
  • the Fig. 1 shows a drive 1 mounted on a revolving door.
  • the revolving door has a leaf 2 designed as a revolving door leaf, which is mounted on a stationary frame 3 via hinges 4 so that it can rotate about a vertical axis of rotation.
  • the drive 1 comprises a housing 5 which is arranged in the upper horizontal area of the frame 3.
  • An output shaft 6 with a vertical axis of rotation is mounted in the housing 5 of the drive 1, with at least one end of the output shaft 6 emerging from the housing 5.
  • a force transmission element 7 designed as a sliding arm is mounted in a rotationally fixed manner.
  • the other end of the power transmission element 7 is guided in a linearly displaceable manner in a guide rail 8 mounted in the area of the upper horizontal edge of the wing 2 by means of a guide element 10, which is designed, for example, as a slider or roller and is rotatably mounted on the force transmission element 7 about an axis of rotation 9.
  • a rotational movement of the output shaft 6 of the drive 1 causes the force transmission element 7 to be pivoted and to move the wing 2 via the guide element 10 guided in the guide rail 8, and vice versa.
  • the drive 1 has a control device, not shown here, which controls the movement sequence of the drive 1, for example depending on sensor signals and / or manual switching operations as well as on the position and / or movement speed of the operatively connected sash 2.
  • the control device can include a memory device in which the parameters required to operate the drive 1, preferably non-volatile, can be stored.
  • the locking device 16 comprises a housing 16, in the chamber of which a spring piston 20 is slidably mounted.
  • the housing 16 can be formed in one piece with the housing of the drive 1 or also separately therefrom.
  • the spring piston 20 divides the chamber of the housing in a liquid-tight manner into two pressure chambers 22, 23.
  • the first pressure chamber 22, on the left in the drawing, is delimited and closed to the outside by a cover 17 of the housing 15.
  • the two pressure chambers 22, 23 are filled with a hydraulic medium.
  • a hydraulic line arrangement 25 which connects the pressure chambers 22, 23 to one another.
  • a damping valve 26 is present in the hydraulic line arrangement 25.
  • a shut-off valve 27 in the hydraulic line arrangement 25 with a pressure relief valve 28 connected in parallel.
  • the shut-off valve 27 can be switched electrically, advantageously depending on Switching commands of the control device of the drive 1, preferably according to the open-circuit principle, ie that the shut-off valve 27 is in its shut-off position when the current is supplied and automatically switches to the through position when the current is lost or switched off.
  • a compensation chamber 29 located in the housing 16 is connected to the hydraulic line arrangement 25.
  • the compensation space 29 is limited to the outside by a cover 30 which has an opening 31 for air to pass through.
  • a piston 32 is displaceable within the compensation chamber 29 and is guided in a liquid-tight manner against the inner wall of the compensation chamber, the piston 32 being urged to the right in the drawing by a spring 33 supported on the cover 30.
  • Also within the spring piston 20 there is a hydraulic line formed with a check valve, for example a ball valve, between the pressure chambers 22, 23, the check valve allowing the hydraulic medium to flow through from the first pressure chamber 22 into the second pressure chamber 23, from the second pressure chamber 23 into the first However, pressure chamber 22 blocks.
  • the cover 17 has an opening 18 through which a piston rod 19 extends, the opening 18 having a seal which allows the piston rod 19 to move, but seals it in a liquid-tight manner.
  • the piston rod 19 is connected at one end to the spring piston 20 and at the other end to a slide 13.
  • the slide is mounted displaceably within the drive 1 and has an elongated, for example oval, recess 14 through which the output shaft 6 of the drive extends.
  • On the output shaft 6, a cam 11 is rotatably mounted.
  • the cam disk 11 is designed with a symmetrical, here heart-shaped outer contour, although other shapes are also conceivable.
  • a pressure roller 12 is arranged, which with the outer contour the cam 11 interacts in that the pressure roller 12 is urged against the cam 11 by the spring device 21.
  • the output shaft 6 is operatively connected to a drive motor device of the drive 1, which is not shown here because it is not essential to the invention.
  • the drive motor device can have an electric drive motor in a known manner, which cooperates with the output shaft 6 via a suitable reduction gear so that a current flow to the drive motor triggered by the control device of the drive 1 causes a rotation of the output shaft 6 and thus also a corresponding movement of the connected leaf 2 causes in the opening or closing direction.
  • Fig. 2 shows the drive in a first operating state.
  • the output shaft 6 is in a position which corresponds to the closed position of the operatively connected vane 2.
  • this operating state which can exist, for example, before the drive 1 is put into operation for the first time, the spring device 21 is relatively slightly pretensioned and acts on the pressure roller 12 of the carriage 13 against the cam 11 of the output shaft 6.
  • a supply of current to the drive motor device can now cause the output shaft 6 to rotate, for example clockwise, and thus a corresponding opening movement of the connected leaf 2. This is shown in FIG Fig. 3 shown.
  • the cam 11 By rotating the cam 11 (direction of arrow B), the effective radius of the point of contact with the pressure roller 12 increases, so that the carriage 13 and the piston rod 19 connected to it are shifted to the left in the drawing (direction of arrow C).
  • the spring device 21 is now maximally pretensioned via the spring piston 20.
  • the shut-off valve 27 in the hydraulic line arrangement 25 is also still in the through position in this operating state.
  • the check valve 24, which is also open in this direction of movement of the spring piston 20, enables the hydraulic medium to flow through virtually undamped from the decreasing first pressure chamber 22 into the correspondingly increasing second pressure chamber 23
  • the piston 32 located there is displaced to the right in accordance with the volume fraction of the piston rod 19 moving out of the first pressure chamber 22.
  • the output shaft 6 and the cam 11 now rotate, actuated by the drive motor device and additionally supported by the relaxing spring device 21, in the counterclockwise direction (arrow direction B), and the carriage 13 moves to the right in the drawing (arrow direction C).
  • the predetermined angle of rotation of the output shaft 6 is shown, which can correspond, for example, to an opening angle of the wing 2 of 70 °, at which the shut-off valve 27 is switched from its open position into its blocked position.
  • Fig. 5 shows an angle of rotation of the output shaft 6, which is present shortly before reaching the closed position of the wing 2, and in Fig. 6 the position of the drive components is shown with the leaf 2 fully closed.
  • a renewed opening movement of the leaf 2 takes place exclusively actuated by the drive motor device.
  • the drive motor device therefore only has to accelerate the wing 2 and not apply any additional force to compress the spring device 21.
  • the shut-off valve 27 in the hydraulic line arrangement 25 is preferably automatically switched to its open position, and the spring device 21 urges the spring piston 20 to the right in the drawing.
  • the hydraulic medium displaced from the second pressure chamber 23 flows through the damping valve in the hydraulic line arrangement 25, so that the movement of the spring piston 20 and the components that are operatively connected to it (arrow direction C), in particular the pressure roller 12, are dampened. This prevents the pressure roller 12 from hitting the cam disk 11, thus protecting the drive 1 from damage and / or preventing disturbing noises.
