Definitions

  • the invention relates to a collection device for a wing of a door or a window according to the preamble of claim 1.
  • a door closer is known, with an acted upon in the closing direction with a closing spring shaft, which is provided with a Hubkurvenin. Furthermore, a hydraulic damping device is provided, which has a further arranged on the shaft Hubkurvenin, the contour of which rotation angle dependent same rotational angle units of the shaft changing adjustments of the damping piston are assigned.
  • the invention has for its object to provide a collection device for a wing of a door or a window whose wing is largely free to move, but also safely guided into its closed position.
  • the collection device is provided for a pivotable door whose wings are mounted in hinges on a frame.
  • the pull-in damping is designed so that the wing is freely movable over a wide range, as if no device was arranged on the door. Only in the area near the closed position of the wing of the wing is actively drawn into this closed position. The retraction movement is additionally damped to avoid a sharp slamming of the wing.
  • the pull-in damping may optionally provide a locking position for the wing in an open position in which the wing is held.
  • the locking position can be released manually by moving the sash in the closing direction.
  • it may be provided beyond the locking position, that the opening movement is inhibited to prevent, for example, a striking of the wing on a wall, a piece of furniture or the like.
  • an intake device 3 integrated in a wing 1 of a door for the pivotally hinged wing 1 together with an associated frame 2 is shown.
  • a slide rail 4 is installed, in which a slider 5 is guided.
  • the slider 5 is rotatably disposed at one end of an actuating arm 6, wherein the other end of the actuating arm 6 is rotatably connected to a provided on a shaft 8 receptacle 9 of the feeder device 3.
  • the collection device 3 can also be integrated in the frame 2 and the slide rail 4 in the wing 1. It is also possible on the wing 1 or the frame 2 resting arrangement of the collection device 3 and der Gleitschiene 4th
  • the intake device 3 has a filled with a hydraulic fluid housing 7, in which the shaft 8 is rotatably mounted.
  • a damping piston 10 and a working piston 11 are further arranged, wherein acting on the working piston 11, a closing spring 12 as energy storage and on the damping piston 10, a return spring 13.
  • the end of the housing 7 is closed with lids 14, 15, wherein the closing spring 12 is supported on one cover 14 and the return spring 13 on the other cover 15.
  • valves 16, 17 are arranged, whereby in a direction of movement against the return spring 13 damping of the piston movement is effected by the valve 16 designed as a throttle, which allows only a throttled overflow of hydraulic fluid. In the opposite direction, an unthrottled overflow of hydraulic fluid through the designed as a check valve valve 17, whereby no damping of the piston movement takes place.
  • the working piston 11 has a longitudinal groove 18, in which a arranged in the housing 7 pin 19 engages, whereby a rotation of the working piston 11 to its longitudinal axis is avoided.
  • the working piston 11 further has a rotatably mounted roller 20 at its end facing the shaft 8.
  • the damping piston 10 has at its end facing the shaft 8 a rounded extension 21.
  • the shaft 8 has three sections with Hubkurvenin 22, wherein between two outer, identical Hubkurvenin 22 with working contours 24 a Hubkurvenin 22 is arranged with a damping contour 23, as shown in the FIGS. 3 and 4 is shown.
  • the Hubkurvenin 22 are symmetrical, whereby the collection device 3 is used on left or right hinged doors.
  • the roller 20 of the working piston 11 corresponds to provided at the outer ends of the roller 20 races 25 with the respective associated working contour 24.
  • the races 25 form a recessed portion of the roller 20, which spaced the roller 20 in the region of the damping contour 23 of this.
  • the projection 21 of the damping piston 10 corresponds to the damping contour 23.
  • a tilting of the working piston 11 within the bore in the housing 7 is avoided by the arranged at the outer ends of the roller 20 races 25 on the two spaced Hubkurvenissuen 22 with identical Support working contour 24.
  • An additional guidance of the working piston 11 can be achieved by the engagement of the damping contour 23 in the region between the races 25 of the roller 20. As a result, the wear is reduced and a low-friction guidance of the working piston 11 is achieved.
  • the damping piston 10, which is acted upon only with respect to the closing spring 12 substantially weaker return spring 13 is guided wear and low friction with the end portion and the extension 21 between the two Hubkurvenin 22 with the working contour 14.
  • Fig. 5 is the section V according to Fig. 4 as a cutout in the area around the cams 22 with the damping piston 10 associated damping contour 23 and with the working piston 11 associated working contour 24 shown wherein the collection device 3 is in its starting position with the wing 1 closed the door.
  • FIGS. 5 to 9 the shaft 8 is shown at different axial angles ⁇
  • the in Fig. 5 shown axis angle ⁇ of the shaft 8 is here 12 °, which corresponds due to the offset of the receptacle 9 of the closed position of the wing 1 of the door with a door opening angle of 0 °.
  • the FIGS. 6 to 9 show the arrangement at different axial angles ⁇ , as described below, wherein for reasons of clarity in the FIGS. 6 to 9 the axis angle ⁇ is not shown, but this is apparent from the position of Hubkurvenin 22.
  • the working piston 11 is first displaced by the roller 20 along the working contour 24 against the closing spring 12 when opening the wing 1 by the rising working contour 24, whereby an opening force for clamping the closing spring 12 on the wing 1 is required, which the Energy for later closing saves.
  • the extension 21 along the in the range between 0 ° and an axis angle ⁇ from here about 60 ° straight damping contour 23 is performed.
  • hydraulic fluid freely through the valve 17 into the space between the damping piston 10 and the lid 15, in which the Return spring 13 is located, overflow. A damping of the wing movement does not take place in this area.
  • the transition is shown in a further region of the working contour 24 in which it is sloping, whereby the spring-loaded working piston 11 generates a torque on the shaft 8, which causes the wing 1 experiences a force in the opening direction.
  • the roller 20 of the working piston 24 enters the in Fig. 8 shown position which corresponds to a locking position for the wing 1 in an open position from here about 130 °, in which the wing 1 is guided by the collection device 3.
  • the collection in the locked position is damped, since the extension 21 of the damping piston 10 now follows the rising damping contour 23 and the damping piston 10 moves against the return spring 13, whereby hydraulic fluid through the valve 16, which throttles the flow of hydraulic fluid flows.
  • an overshoot or overpressure from the locking position in the opening direction is counteracted by the again rising working contour 24 and the thus required increasing force required by the spring-loaded working piston 11, as it is in Fig. 9 is shown.
  • This is an opening loss achieved for the wing 1, for example, to avoid hitting the wing 1 on a wall.
  • the peculiarity of the intake damping 3 is, however, that the freely movable wing 1 is pulled close to its closed position automatically in the closed position of the wing 1. It is thus only necessary to abut the freely movable wing 1 in the closing direction, and the door is securely closed as soon as the wing 1 comes close to the closed position.
  • the shaft 8 now in the reverse direction, enters the in Fig. 6 shown position, which adjoins a region of strongly sloping working contour 24, whereby the roller 20 of the acted upon by the closing spring 12 working piston 10 generates a high torque on the shaft 8, which retracts the wing 1 in the closed position.
  • the damping also sets in, so that the wing 1 does not hit violently, wherein the damping contour 23 are matched to the extension 21 and the working contour 24 to each other.
  • the wing 1 between the locking position and an axial angle ⁇ from here about 60 ° according to a door, which has no feed device 3, is freely movable. It can also be dispensed with a locking position and beyond on a damping in the opening direction, which are advantageous in practice.
