Definitions

  • the invention relates to a door closer according to the preamble of claim 1.
  • the DE 34 11 189 A1 discloses an automatic door closer with a detachable with a door wing output shaft which is rotatable from a closed position in both directions and within the housing with a Hubkurvenin form fit between rollers of a longitudinally movable carriage, to which a memory forming spring arrangement and the piston of a hydraulic damping device attack.
  • the interior of the door closer housing is divided into two separate by the piston pressure medium spaces.
  • the pressure medium spaces are connected to each other by separate channels, each with a closable throttle valve to flow out of the pressure medium from the shrinking when closing the door pressure chamber and a piston arranged in the opening movement of the door opening check valve.
  • the separate channels are alternately blocked and released by a piston displaceable by the spool, wherein in each channel a pressure medium spaces, if necessary, connecting safety valve is connected.
  • the stroke end position of the spool is adjustable with respect to the piston, whereby the transition of two different damping regions of the closing movement is adjustable.
  • the arrangement is complex due to many components and sealing points and may be prone to failure.
  • the damping of the closing speed is possible only in two stages, with only the Umstelltician is adjustable. An opening damping is not available.
  • the starting point of the opening damping with respect to the door opening angle is determined by the position of the valve in the flow channel.
  • the invention has for its object to form a door closer, the point of use for the opening loss is adjustable.
  • the dampening of the door prevents the door from slamming against, for example, a wall, a piece of furniture or the like, thereby preventing damage to both the door panel and the wall or furniture.
  • the point of application of the opening damping is advantageously adjustable in order to be able to open the door leaf undamped over the widest possible range of the door opening.
  • the position of the piston of the door closer is directly related to the opening angle of the door, since the output shaft of the door closer via a gear assembly, for example with a cam or a pinion, is connected to the piston, wherein the rotational movement of the output shaft of the gear assembly in a sliding movement of the Piston is reacted, and vice versa.
  • a gear assembly for example with a cam or a pinion
  • the door closer has to adjust the point of application of the opening damping on a switching valve which comprises a magnet which is adjustably received in a recess in the housing and acting on a valve ball in an overflow channel in the piston of the door closer, wherein in the overflow one of the valve ball associated valve seat is arranged.
  • the position of the magnet with respect to the piston determines the point of application of the opening damping, in which the valve ball rests on its associated valve seat and closes the overflow channel in the piston.
  • the switching valve causes an opening or closing of the overflow.
  • the hydraulic fluid in the door closer can flow only in the case of a movement of the piston in the opening direction via an externally adjustable throttle valve for the opening damping arranged in the housing of the door closer.
  • the position of the magnet is adjustable with respect to the piston or valve elements on the valve ball and valve seat in the piston, including, for example, a clamping device, not shown here may be provided which allows a continuous displacement and fixing of the magnet along the recess in the housing.
  • the door closer 1 comprises a housing 2, in which a cam disc 3 is arranged non-rotatably on an axle 4 which forms the output shaft of the door closer 1 and is rotatably mounted in the housing 2.
  • a slidable along the door closer 1 slide 5 is further provided, which at one end has a rotatably mounted roller 6, which cooperates with the contour of the cam 3.
  • a piston rod 7 is fixed, which has a piston 8 at its end facing away from the carriage 5 end.
  • the piston 8 is sealed in the formed in this area as a bore housing 2 against the inner wall, so that on the one hand of the piston 8, a spring chamber 12 is formed.
  • the bore in the housing 2 is closed at the end with a closure cap 13, whereby a piston chamber 14 is formed between the piston 8 and the closure cap 13.
  • the interior of the housing 2 is filled in a known manner with hydraulic fluid, so that in the spring chamber 12 and the piston chamber 14 is hydraulic fluid.
  • a compression spring 9 is arranged, which is supported on the piston 8 and on a spring plate 10.
  • the spring plate 10 is operatively connected to a Sch spakraftverstell till 11, which allows a displacement of the spring plate 10 with respect to the piston 8, whereby the compression spring 9 can be biased to adjust the closing force of the door closer 1 to different door weights can.
  • FIG. 2 is a section of another section plane through the door closer 1 according to FIG. 1 shown, but the section runs above the piston rod 7 so that it is no longer cut.
  • throttle valves 15 are provided, which are arranged in overflow channels 16 in the housing 2, whereby a controlled overflow of the hydraulic fluid between the spring chamber 12 and the piston chamber 14 on both sides of the piston 8 is possible.
  • check valves 17 are provided in the overflow channels, which force an overflow of the hydraulic fluid depending on the direction of movement of the piston 8 and thus the flow direction of the hydraulic fluid via different overflow 16.
  • valve ball of the check valve 17 may be provided in the associated overflow 16 laterally projecting in this fuse elements 18.
  • overflow channels 16 are closed at the ends by means of closure elements 19, which are designed here as balls pressed into the overflow channels 16.
  • FIGS. 3 and 4 an enlarged section of the area of the piston 8 of the door closer 1 is shown.
  • the piston 8 is located in one, depending on the door opening angle, different position within the bore of the housing. 2
  • a switching valve 21 which has an adjustably arranged in a recess 20 of the housing 2 magnet 22, which is connected to a in the overflow 16.2 recorded, consisting of ferromagnetic material valve ball 23 in the piston 8 acts.
  • the recess 20 for the magnet 22 advantageously has no connection to the interior of the housing 2, whereby no seal with respect to the hydraulic fluid to the interior is required.
  • the recess 20 in the housing 2 is arranged so that it lies in the displacement region of the piston 8.
  • the magnet 22 acts on the valve ball 23 by the at least in this area non-ferromagnetic, advantageously made of aluminum or plastic housing 2.
  • the piston 8 is also at least partially made of a non-ferromagnetic material or made of plastic
  • valve ball 23 may also be provided a valve cone or otherwise shaped valve element.
  • the magnet 22 can lift the valve ball 23 from its associated valve seat.
  • the valve seat is formed on a taper 24 in the overflow 16.2. In the overflow channel 16.2 the other end of the taper 24 is another valve seat of a check valve 17.2 formed.
  • Fig. 2 the arrangement of the opening damping is shown with adjustable starting point when opening the door, wherein the starting point of the opening damping is set here to about 110 ° door opening angle.
  • the door opening angle is just at about 5 °, whereby the piston 8 is near its end position (in the figure right) and the volume of the piston chamber 14 is still low.
  • Fig. 4 the arrangement of the opening attenuation at the point of use is shown at a here, for example, set door opening angle of about 110 °, which is effected by adjusting the axially adjustable received in the recess 20 magnet 22 of the switching valve 21.
  • the piston 8 has been moved so far in the direction of the compression spring 9, that held by the magnet 22 valve ball 23 now rests on its valve seat on the taper 24, whereby the overflow 16.2 is closed.
  • the hydraulic fluid which is located in the spring chamber 12, can flow in the further movement of the piston 8 in the direction of the compression spring 9 only via the throttle valve 15.1 for the opening damping, the overflow 16.1 and the open check valve 17.1 in the piston chamber 14.
