Definitions

  • the invention relates to an automatic door closer according to the preamble of claim 1. It is preferably a pinion-type door closer or crank-mechanism door closer according to the German industrial standard 18263. These door closers are used for fire protection doors, smoke protection doors and apartment doors.
  • the energy required for self-closing is usually stored in a helical compression spring.
  • the closing movement is dampened by hydraulic throttling.
  • the damping piston which is displaceable from the outside, is arranged in the damping cylinder between radial throttle bores, which are connected to one another via an overflow channel, each of which connects a pressure space in the cylinder in front of the piston to the unpressurized space behind the piston via a throttle valve.
  • the damping cylinder which simultaneously forms the housing of the door closer, is made in one piece, either as a die-cast part or as a section of a corresponding continuous cast hollow profile, preferably made of a light metal.
  • the manufacture of such cylinders is difficult with regard to the tightly tolerated mount for the damping piston and the necessary long overflow channel and the throttle bores and requires special machine tools.
  • the mount for the damping piston must be manufactured with high tolerance accuracy.
  • the overflow channel which usually runs parallel to the damping piston in the one-piece cylinder, is particularly difficult to manufacture, and can be connected precisely from the outside or from the inside to the throttle bores arranged transversely.
  • the object of the invention is to simplify an automatic door closer of the type mentioned in production terms.
  • prefabricated pipe sections can be used as damping cylinders which are already sufficiently tightly tolerated with regard to the piston holder.
  • the formation of the overflow channel between the outside of the tubular damping cylinder and the tightly fitted cover element avoids the previously required complicated bores in the damping cylinder.
  • the cover elements which adapt to the outer shape of the tubular damping cylinder require only a very small increase in the outer diameter of the cylinder.
  • a groove is welded on the outside of the tubular damping cylinder as a cover element with an outwardly pronounced cavity which is open towards the tubular hollow cylinder and which forms the overflow channel with the tubular hollow cylinder.
  • Covering elements of this type can be attached to the tubular hollow cylinder using a known welding method, without thermal stress affecting the tightly tolerated cylinder receptacle.
  • the invention also includes the proposal according to claim 3 to form the respective cover element in one piece with the subsequent throttle valve housing, so that in this case the possible two individual elements are placed together in a sealed manner on the damping cylinder and can preferably be fastened by a welded connection.
  • FIGS. 1-6 Two half-shells 1 and 2 form a cylinder receptacle in which a tubular hollow cylinder 6 forming the door closer housing is positioned and sealed in a form-fitting manner is included.
  • the housing shells lie against each other in the division level 4.
  • the number 3 indicates an additional cover shown in dashed lines.
  • the two half-shells 1 and 2 are braced against one another via the screw connections 5.
  • the tubular hollow cylinder 6 is closed at the end by the plug 66.
  • a hydraulic piston 8 which is displaceable from the outside via a corresponding connecting rod or the like, not shown, separates a pressure chamber 61 from a non-pressurized chamber 62.
  • two radial throttle bores 63 and 64 open into the pressure chamber 61 open into an overflow channel 21 in the half-shell 2 parallel to the cylinder axis.
  • this overflow channel 21 is molded openly into the hollow hollow cylinder 6 in the cylinder receptacle of the half-shell 2.
  • a seal receptacle 22 is formed around the overflow channel 21 and a molded seal 9 is inserted into it.
  • Other types of seals can also be used here.
  • the bores 23 and 12 shown in FIGS. 5 and 6, which are used to pass the drive linkage, are also surrounded by a seal receptacle 24.
  • the seals 10 to be arranged therein can be seen in FIG. 5.
  • the tubular hollow cylinder 6 is also excluded at the corresponding points.
  • the hydraulic piston 8 is displaced in the direction of the sealing plug 66.
  • the hydraulic fluid flows out of the pressure chamber 61 through the throttle bores 63 and 64 via the overflow channel 21 Throttle valve 7 and from this valve to the unpressurized space 62.
  • the throttle valve 7 projects with its valve cone 71 into the bore 65 formed as a valve seat on the hollow cylinder 6.
  • the throttle valve 7 is inserted radially into the half-shell 2 with the seal 62 and is adjustable from the outside.
  • the hollow cylinder 6 is positioned between the half-shells 1 and 2.
  • a cam 11 provided in the half-shell 1 engages in a corresponding recess 67 on the outside of the hollow cylinder 6.
  • FIGS. 7-10 A less technically complex construction of a door closer housing is shown in FIGS. 7-10.
  • the housing is formed by the tubular hollow cylinder 106, which can be a section of a prefabricated tube with a tightly tolerated inner diameter.
  • the hollow cylinder forms the interior for the hydraulic piston 108.
  • the two throttle bores 163 and 164 are provided in the radial direction.
  • the overflow channel 121 is arranged on the outside of the hollow cylinder 6. It is formed by the channel 102, which is fastened tightly on the tubular hollow cylinder 106 using a suitable welding method.
  • the throttle valve 107 or its valve housing is attached to the channel 102. This housing can also be fastened with a welded connection or a suitable other connection.
  • the overflow channel 121 formed connects the throttle bores 163 and 164 with the bore 165 to the unpressurized space.
  • the valve cone of the throttle valve 107 acts against this bore 165.
  • bushings 112 and 123 are arranged transversely to the axis on the hollow cylinder 106.
  • the tabs 103 serve to fasten the housing.
  • FIGS. 11 and 2 show the tubular hollow cylinder 206 of an automatic door closer, in which a groove-like depression is formed on the outside in the region of the throttle bores 263, 264 and 265 in order to form the overflow channel 221.
  • a partially shell-shaped cover element 202 is placed in a sealed manner over this depression and is preferably fastened with a welded connection.
  • the cover element 202 is already connected to the housing of the throttle valve 207 in the same material.
