Definitions

  • the invention relates to a freewheel device for driving a wing Door or window according to the preamble of claim 1.
  • Freewheel devices allow a wing with a drive decouple a door or window from the drive. This enables to operate the wing freely, corresponding to a wing on which none Drive would be arranged. Freewheel devices work with a locking device together, which blocks the energy storage in the door closer. The blocking can be picked up, allowing the wing to be opened by the door closer its closed position is managed. This is particularly the case with fire doors used to close the wings in the event of a fire and thus the spread of fire to delay or even prevent it.
  • From DE 92 09 276 U1 is an overhead door closer with a slide rail linkage known for concealed installation in a door leaf or door frame, with a closer shaft which can be actuated by a spring arrangement in the closing direction and one with this damping piston operatively connected and with one with the Closer shaft of a pivoted actuating arm that is coupled at the end another slider arranged in another in a door frame or in one Door wing recessed slide rail holds.
  • the closer shaft has one Cam disc, with the NO shaft end not emerging from the housing is stored in an axle bearing within the housing.
  • the door closer is suitable for installation in the door leaf or door frame however, no freewheel device.
  • DE 198 40 766 A1 describes a drive for a wing of a door or one Known window, with a drive housing, with one in the drive housing arranged reset device, which when opening or closing the wing is acted upon and as an energy store for automatically closing the Wing is formed with a damping device arranged in the drive housing to dampen the closing and / or opening movement of the Wing, with an output member arranged in the drive housing, which cooperates with the reset device and / or damping device with a power transmission linkage, which on the one hand in a rotary or Slide bearing is supported and on the other hand is connected to the output member.
  • the power transmission linkage is freely rotatable on the output member or stored in the area of the output member, and a locking lever is rotatable with the Output link connected, lockable with a holding device.
  • a disadvantage is the space required for the freely rotatable linkage.
  • the device also requires an additional electromagnetic to be placed on the door frame The fixture. When used on DIN left or DIN Doors hinged on the right must be turned to close the door Linkage with the freewheel device on the opposite shaft end the closer shaft to mount because the shaft rotates in the opening direction with pinion door closers is only possible in one direction.
  • DE 32 46 457 A1 shows a door closing device consisting of one arranged in a housing when the respective door swings open unit for clamping force generation that can be tensioned from the closed position, one with this unit connected and led out of the housing drive shaft, one connected to the drive axle via a one-way clutch for actuation the lever to be closed, a unit for generating the closing force, and at least in a predetermined opening angle range can be blocked in the closing direction at the end of the swing-open movement Locking arrangement, which can be optionally activated and / or depending on control signals can be switched off.
  • the one-way clutch consists of one, one predetermined stroke a relative rotation between the operating lever and drive axle approved thread rotation, and from at least on provided a stroke end, one effective with respect to the actuating lever becoming frictional stop, the between the operating lever and Holding force setting the frictional stop is smaller than the holding force the block the unit for generating the closing force in the closing direction Lock assembly.
  • a disadvantage of this device is the space required for the one-way clutch between the housing and the operating lever.
  • the friction stop is difficult to adjust and more frequent due to possible wear readjust.
  • the invention has for its object a freewheel device for the drive form a wing that has a low profile and thus for integrated door closer is suitable.
  • the drive is for DIN left and DIN doors hinged on the right can be used.
  • Drives for the wing of a door or window can rest on the wing or integrated in the sash or in a frame or a frame his.
  • the drive has an energy store, which when opening the Wing stores the energy required for closing.
  • This is for example with a drive for the wing of a door, which is on or in the wing is mounted, an actuating arm between the drive and one in or on the Frame mounted slide rail arranged.
  • the drive end of the actuator arm interacts with an output shaft of the drive, whereby the other end of the actuating arm has a slider, which in the Slide rail is guided.
  • the drive In order to allow the wing to move freely, there is a freewheel device on the drive arranged. It is advantageous here that the drive only at the first Opening the wing the energy required to close it can be supplied must then be actuated like a wing without a drive can.
  • the drive has a freely rotatable receptacle on the output shaft for the operating lever. Furthermore, a rotationally fixed is below this recording driving disc connected to the output shaft, which is semicircular.
  • the actuating arm points in the area around the receptacle two opposite bores, which can have threads, and in which a driver can be used. This allows the drive used for both left hinged and right hinged doors become.
  • the driver is designed such that it is in the inserted state the plane of the semicircular drive plate protrudes.
  • the hole in which the driver is used is arranged in a rotationally fixed manner on the output shaft Driving disc rotated by the driver.
  • the spring piston and the damping piston is moved over the cam disc, the energy is stored in the closing spring and the hydraulic fluid flows from one side of the damping piston over to the other side.
  • the energy stored in the closing spring causes the spring piston the cam disc arranged on the output shaft turns back, whereby the damping piston is also pushed back and the hydraulic fluid flows back again.
  • the valve can be operated electromagnetically, and the backflow of the Hydraulic fluid can be released again. For example on a fire door by a smoke alarm system.
  • the energy stored in the closing spring can be the output shaft turn back with the drive plate over the spring piston and the cam disc. If the drive plate comes into contact with the drive arm driver, the rotary motion is transferred to this, causing the wing is led into its closed position.
  • FIGS. 1 and 2 there is a drive 3 integrated in a wing 1 of a door shown, together with an associated frame 2.
  • frame 2 is the Slide rail 6 installed, in which the slider 5 is guided.
  • the slider 5 is on one end of an operating arm 4 rotatably arranged, the other end of the actuating arm 4 with a receptacle 14 of the drive 3 rotatably connected is, and cooperates with the drive plate 13 of the drive 3.
  • the Drive 3 can also be integrated in frame 2 and slide rail 4 in wing 1 his.
  • the drive 3 has a housing 7 in which a spring-loaded damping piston 8 and a spring piston 9 are arranged.
  • a closing spring 10 acts as an energy store, which is adjusted via a closing force 15 can be biased to drive 3 on different wings 1 adjust.
  • the damping piston 8 divides the interior of the housing filled with hydraulic oil two areas in front of and behind the damping piston 8. Through valves in the piston and through overflow channels in the housing, which are provided with throttle valves the behavior of the drive 3 can be influenced. So the opening damping, Closing damping, the final stroke and a determination of the wing 1 run.
  • the settings can be manual or electromagnetic or done by an electric motor.
  • An output shaft is located between the damping piston 8 and the spring piston 9 11 arranged, which is rotatably mounted in the housing 7. On the output shaft 11 is rotatably connected to this, a cam disc 12 is arranged.
  • the Stroke cam 12 is symmetrical, for example a heart curve around the Actuator for installation on left and right wing 1 to be able to use.
  • the output shaft 11 points out of the housing 7 of the drive 3 emerging shaft end a rotationally connected driving plate 13 on and a freely rotatable receptacle 14 for the actuating arm 4.
  • the driving plate 13 with the receptacle 14 is shown in FIG. 4.
  • the drive plate 13 is recessed in a semicircular shape and has two depressions in which a catch 16 which can be fixed on the actuating arm 4 engages can.
  • the actuating arm can on the Mount 14 and screwed, the actuator arm 4th can rotate freely without the closer shaft 11 also being rotated.
  • the operating arm 4 comprises two bores 18, which may have a thread.
  • the damping piston 8 and the spring piston 9 each have on their the output shaft 11 facing end each have a rotatably mounted roller 17, which roll on the cam disc 12 of the output shaft 11. Will the Output shaft 11 by opening the wing 1 and the resulting movement of the actuating arm 4 via the driver 16 and the driving plate 13 rotated, the damping piston 8 and the spring piston 9 by the Stroke cam 12 shifted. The rotary movement is implemented the output shaft 11 in a linear movement.
  • the spring piston moves 9 such that the closing spring 10 is tensioned by compression and thus stores the energy required to close the wing.
  • the spring-loaded damping piston 8 is also moved, the hydraulic oil from one piston side to the other piston side through overflow channels can flow.
  • the backflow of the hydraulic fluid can be prevented by a valve, whereby the damping piston 8 move when opening the wing 1 can, but cannot move back again.
  • the output shaft 11 is fixed to it Driving plate 13 blocked in the closing direction.
  • wing 1 If wing 1 is closed with the valve closed and the drive plate blocked 13 in the direction of its closed position, the driver 16 the actuating arm 4 from its contact in the recess of the drive plate 13, since the actuating arm 4 is arranged on the freely rotatable receptacle 14.
  • the wing 1 can now, decoupled from the drive 3, corresponding to a wing 1, on which no drive 3 is arranged, can be moved freely.
  • the damping piston 8 can move back again, and the output shaft 11 with the drive plate 13 rotates back.
  • the driver 16 the rotational movement of the output shaft 11 is on the actuating arm 4 transferred, whereby the wing 1 is guided into its closed position becomes.
  • This is particularly advantageous for fire doors, which are in the event of danger must be closed, but the door is not always in normal operation must be opened against the closing force of the actuator 3.
