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 a switching valve whose adjustable valve tappet is accommodated in a closure cover of the housing of the door closer and engages in an overflow channel in the piston of the door closer, a valve ball and an associated valve seat being arranged as valve elements in the overflow channel.
  • the position of the valve stem 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.
  • valve stem is adjustable with respect to the piston or the valve elements valve ball and valve seat in the piston by the valve stem is sealed in a thread sealed to the outside in the cap, wherein the valve stem is axially displaced by rotation.
  • 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.
  • FIGS. 2 to 4 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.
  • the piston 8 is located in one, depending on the door opening angle, different position within the bore of the housing 2.
  • 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 spring chamber 12 and 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.
  • a switching valve 21 is provided for determining the point of application of the opening damping, which has an adjustable valve stem 22 which is accommodated in the closure cap 13 and engages in the overflow channel 16.2 in the piston 8.
  • the valve tappet 22 can lift off the valve ball 23, which is preferably acted upon by a valve spring 20, from its associated valve seat.
  • the arrangement of valve stem 22 with the preferably spring-loaded valve ball 23 in the overflow 16.2 with the associated valve seat form the switching valve 21.
  • the valve ball 23 may also be provided a valve cone or otherwise shaped valve element.
  • the valve stem 22 is received in the closure cap 13 in a thread and sealed to the outside.
  • the valve stem 22 has a tool holder 24, for example, for an Allen key or a screwdriver, wherein by rotation of the valve stem 22, an axial displacement of the valve stem 22 takes place.
  • 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 on the right) and the volume of the piston chamber 14 is still low.
  • Fig. 3 the arrangement of the opening damping at the point of use is shown here at an example set door opening angle of about 110 °, which is effected by adjusting the axially adjustable mounted in the closure cover 13 valve stem 22 of the switching valve 21.
  • the piston 8 has been moved so far in the direction of the compression spring 9 that the valve stem 22, the valve ball 23 releases, which is displaced by the flowing hydraulic fluid and additionally by the valve spring 20 in the direction of its valve seat and now rests on the valve seat, whereby the overflow 16.2 closed is.
  • 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.
  • Fig. 4 shows the arrangement when closing the door, the piston 8 is pushed back to its original position and here is in a position corresponding to a door opening angle of about 60 °.
  • the hydraulic fluid from the piston chamber 14 is thereby pressed by the piston 8 via the overflow 16.3, the throttle valve 15.2 for the closing speed and - in still further closing - the throttle valve 15.3 for the final blow back into the spring chamber 12.
  • Due to the flow of hydraulic fluid the check valve 17.3 is open, the check valves 17.1 and 17.2 are closed.
  • the valve ball 23 for the opening damping is lifted by the valve stem 22 of the switching valve 21 again from its valve seat, but no overflow of hydraulic fluid via the overflow 16.2 takes place during the closing movement, since the check valve 17.2 is acted upon in the closing direction.
