Definitions

  • the invention relates to a drive for a door, window or the like with the Features of the preamble of claim 1, preferably a manual door closer.
  • Hydraulic door closers with closer springs are known. During the opening movement the closer spring is compressed by hand. This results in a adverse opening resistance. The closing movement then takes place automatically under the action of the closer spring. In practice it is important that the closing moment shortly before reaching the closed position is relatively high to the lock latch to be able to overpress. With conventional door closers, this means that the opening resistance is particularly high in the area of small opening angles and is annoying.
  • a door closer which also has a closer spring has as an energy store. Between the closer spring and the door closer shaft a cam gear is switched, which has a transmission ratio that varies over the door rotation angle he brings. The door angle-dependent course of the gear ratio is however the same when opening and closing.
  • the invention has for its object a drive of the type mentioned to develop further so that the drive is high with a structurally simpler construction Provides ease of access and also ensures secure closing.
  • a structurally simpler and functionally reliable door closer who have a non-disturbing opening resistance when opening, so that a comfortable manual opening is possible and one safe automatic closing, e.g. B. guaranteed by overcoming the lock latch is.
  • the different torque curve provided by the invention when opening and when closing means that the path-dependent torque curve when opening and runs differently when closing, d. H. thus the path dependency of the opening torque, which represents the opening resistance is different from the path dependency the closing torque that forms the automatic closing action.
  • a control device can be used to switch the torque characteristic at certain door rotation angle can be provided, whereby it can be realized that at a certain door rotation angle, a transition from the one torque characteristic to another torque characteristic.
  • the control device can be switched in this way be that a torque characteristic in the opening direction and in the closing direction the other torque characteristic takes effect.
  • the control cam can be formed on a cam disc and indirectly or interact directly with the energy storage, e.g. B. via an intermediate Pressure piece.
  • Preferred embodiments of this principle can be used as a door closer with a cam gear be executed.
  • the control cam is formed on a cam, preferably two cams are present, namely a first cam with a first cam which forms the opening cam and a second cam with a second cam that forms the locking cam.

  • opening and closing the door is done by switching between the switch pin tracks 6 and 7 achieved a different path-force curve.
  • the switching pins run during the opening process (due to the specified direction of rotation the door) inevitably on the flatter tracks 6 of the movement sleeve. Since the path 8 on the switching sleeve runs steeper than the corresponding one Lane 6 on the movement sleeve, the switching sleeve is relative to the switching pin twisted to the motion sleeve. If the door is over the switch angle (here ⁇ / 16) open out, the switching edge 9 blocks the path of the switching pin back to the flat track.
  • the coil spring 3 is tensioned over the pressure plate 12 by the switching pins.
  • the pressure plate is opposed by the plate 13 against twisting the bearing pin 15 secured by the plate 13 in an axial longitudinal groove in Bearing pin 15 engages.
  • the bearing pin 15 can be stationary, d. H. fixed frame and the sleeve 5 with the door leaf 50 firmly be trained.
  • the coil spring 3 acts as a closer spring.
  • the steeper the shift pin path the more the resulting force component is greater in the circumferential direction of the sleeve 5, which determines the torque.
  • the steep section is preferably located with door angles less than 90 degrees, especially less than 40 degrees. The vertex the turn forms the switchover point, in the present case 40 degree rotation angle.
  • the door closer of Figures 6 and 7 has two cam-shaped cams on an opening cam 16 and a closing cam 17.
  • Es the gearbox is a cam gear with a switchable characteristic.
  • the compression spring 14 serves as a closer spring.
  • Opening and closing cams have in the end position (closed door) c) the same radius b.
  • the pressure piece is activated by a suitable mechanism after reaching the end position pushed back on the opening cam.
  • the compression spring 14 acts as a closer spring.
  • the cams form the output side of the door closer.
  • the closer shaft can as with conventional door closers directly or via a force-transmitting linkage be connected to the door leaf.
  • the cam device shown can be equipped with a damping device, not shown be connected, e.g. B. also attacking the closer shaft.
  • the cam device and the damping device can be in one Housing be arranged, such as in a conventional floor closer.

  • the door closer according to the principle in Figure 9 works in a corresponding manner.
  • the energy store 90 is in this case with a piston-cylinder unit smaller effective cross-section connected, a valve 91a is interposed.
  • the piston is connected to a piston of a second piston-cylinder unit 92, e.g. B. via a piston rod.
  • An overflow line 93 connects the two cylinders.
  • the small piston cylinder 91 acts when opening and closing.
  • the larger piston cylinder 92 becomes close at the end of the closing movement Zero degree door rotation angle activated.
  • the system works like an air pump Energy supplied and stored there. By opening it several times, the Memory filled. As soon as the memory is filled, the opening resistance minimal. Relatively little energy may have to be taken from the memory to close are consumed, especially if closing takes place relatively slowly.
  • the pistons of the piston-cylinder systems are coupled to the door in terms of gears, e.g. B. to drive a shaft that forms the closer shaft.
  • the piston rods in Figure 8 can be coupled together in terms of gear.
  • the energy store can also have an additional energy supply for reloading.
  • the torque characteristic curve runs different when opening than when closing.
  • FIGS. 1 to 5 show the torque characteristics shown in FIG. 11 receive. This result is due to the existing path / force curve obtained, which is different when opening and closing, as in figure 10 shown.
  • the closing torque is the same as the opening torque and remains so low until shortly before the closed position, in present case at 8 degrees door angle. There the closing moment rises sharply to a value that is significantly higher than the opening torque. The high closing moment just before the closed position ensures that the door locks closes and the door latch is pushed over. Immediately with an even smaller door angle shortly before the end position, the closing torque can drop again to a little a value that keeps the door closed.
  • This torque curve is only an example. He can in the embodiment of Figures 1 to 5 by appropriate choice of parameters, in particular Design of the control curve - this means appropriate setting of a varying transmission ratio and specifically different when opening and closing - can be set.
