Definitions

  • the present invention relates to a door hinge for stop doors, which has a hydraulic damping.
  • Sprung door hinges have the task of moving an open door back to a closed position.
  • a spring is tensioned by opening the door, which stores the necessary force for the closing movement. So that the spring does not close the door with increasing speed, the door hinges have dampers.
  • a viscous liquid e.g. Oil used, which is moved between two pressure chambers.
  • a disadvantage of the known door hinges is the complicated structure and the insufficient sealing of the tapes, which tend to leak over time.
  • the invention includes the technical teaching that when opening the door rotatably disposed within the housing spindle moves a spindle nut in the axial direction, so that a compression spring is compressed, which supports the closing operation of the door and the door again is moved to a closed position.
  • the spring chamber forms a first pressure chamber for a viscous fluid, which is connected via a channel to a pressure chamber which is located below the spindle nut, wherein a valve regulates the flow of viscous fluid in the channel.
  • valve for regulating the closing damping can be actuated from the lower end side of the housing, without having to disassemble the door hinge, results in an overall dense and compact door hinge.
  • a compact and at the same time robust design of the door hinge is achieved in that the spindle cooperates with the spindle nut via a thread.
  • the design as a trapezoidal or sawtooth thread allows a high load on both components.
  • the bearing is used in a preferred embodiment as a support bearing for the compression spring, as below the bearing a disc is arranged, on which the compression spring is supported. This again reduces the height of the door hinge.
  • a second pressure chamber is arranged below the spindle in the housing, which can be hydraulically connected to the first pressure chamber.
  • the second pressure chamber is connected via a channel in the spindle with the first pressure chamber. So that the regulating effect of the valve is not bypassed, a cavity with a check valve is arranged within the spindle in the channel, which can open only in one direction and is designed for high load peaks.
  • the arrangement of this valve in the spindle also allows a compact design, since the preassembled spindle can be related to the valve as a kit and assembled.
  • FIG. 1 shows a front view of a door hinge 1 with an upper hinge part 7.
  • the door hinge 1 has a housing 2, in which a spindle 5 is rotatably arranged. At the upper end of the spindle 5 is a pin. 6 arranged, for example as a square. Hexagon or octagon.
  • a hinge flap 3 is further attached, by means of which the door hinge 1 is attached to a frame or wall, not shown.
  • 3 holes 4 may be incorporated for attachment to the hinge plate, in this embodiment, two holes 4.
  • Housing 2 and hinge tabs 3 are made in one piece in this embodiment, and for example made of a cast material. Of course, a two- or multi-part design is possible.
  • the upper band part 7 is designed to be fastened to a door, not shown.
  • the upper hinge part 7 also has a hinge flap 10 with holes 9.
  • the hinge tab 10 is connected to a housing 8, which can also be made in one piece or in several parts.
  • a corresponding receptacle for the pin 6 is arranged, which is fixed, that is not rotatable, connected to the housing 8.
  • the upper hinge part 7 can be firmly connected to the wall or frame, and the door with the door hinge 1 via the pin 6 engage in the receptacle of the upper hinge part 7. Due to the sealing of the moving parts within the door hinge 1, the variant described above - ie door hinge 1 is fixed to the wall or frame and the upper hinge part 7 on the door - the better variant, since in this case no moving seals must seal down.
  • the housing bore 2a is designed as a blind hole with a flat base, to which another blind hole 2b connects.
  • the storage of the spindle 5 takes place in this embodiment, by a rolling bearing 14, which may be designed as a needle or cylindrical roller bearings, and is disposed within the housing bore 2b.
  • the rolling bearing 14 is held by a bearing housing 13. Below the bearing housing 13, a thrust washer 15 is arranged, against which a paragraph 5b of the spindle 5 crashes.
  • a retaining ring 18 is arranged in a circumferential groove of the housing 2, so that a pressing out of the bearing housing 13 is avoided.
  • the circlip 18 at the same time prevents the spindle 5 from being pressed out of the housing 2, since it is likewise supported on the circlip 18 indirectly via the bearing housing 13 with the shoulder 5b.
  • the spindle 5 can only rotate with it. An axial movement of the spindle 5 is not possible by the storage described above.
  • Seals 16,17 provide a tightness between the bearing housing 13 and the housing 2, as well as a tightness between the bearing housing 13 and the spindle fifth
  • a thread 5a is arranged as an external thread, which may be formed in this embodiment as a trapezoidal or Sge leopardgewinde. This thread 5a cooperates with a complementary thread 11a as an internal thread of a spindle nut 11.
  • the spindle nut 11 is designed as a cylindrical component which is displaceably guided within the housing bore 2 a along the axis of the spindle 5. A lower end of the spindle nut 11 rests on the flat base surface of the housing bore 2a.
  • the upper end of the spindle nut 11 is formed as a flat surface and objected to the disc 15 arranged so that between the disc 15 and spindle nut 11, a first pressure chamber 19 is formed, in which a compression spring 12 is arranged.
  • the compression spring 12 is supported at one end to the disc 15, and with the other end to the spindle nut eleventh
  • the spindle 5 is mounted in the upper region of the door hinge 1 by the roller bearing 14 with the bearing housing 13 and in the lower region by the spindle nut 11.
  • the spindle 5 can only rotate about its own longitudinal axis, ie move radially, where against the spindle nut eleventh can only perform an axial movement along the axis of the spindle 5.
  • the spindle nut 11 moves up on the thread 5a in the direction of the pin 6, thereby pressing the compression spring 12 together.
  • the stored work of the compression spring 2 then ensures that the door closes again, since the force of the compression spring 12, the spindle nut 11 pushes back down and thus the spindle 5 rotates back.
  • the spindle nut 11 is secured within the housing bore 2a against radial rotation and can only move axially along the axis of the spindle 5.
  • a first pressure chamber 19 is formed by the region of the housing bore 2 a, which is located between the disk 15 and the spindle nut 11.
  • the blind bore 2b in the lower part of the housing 2 forms a second pressure chamber 20.
  • Both pressure chambers 19, 20 are interconnected by a channel 23 which penetrates the spindle 5 transversely and at the same time extends axially within the spindle 5 to the lower end face of the spindle 5 ,
  • a valve 21 is arranged, which is designed as a check valve.
  • the spindle 5 has an end bore, which has a cavity 22 forms and in which the valve 21 is used.
  • the lower end face of the spindle 5 is designed with the inserted valve 21 so that its outer diameter is greater than the diameter of the second pressure chamber 20, so that it is almost sealed by the end face of the spindle 5.
  • Another channel 25 is incorporated parallel to the axis of the spindle 5 in the housing 2 and connects the first pressure chamber 19 with a further pressure chamber 28 which is located below the spindle nut 11.
  • a valve 26 is arranged, which is designed as a regulating valve.
  • the valve 26 is inserted into the lower end face of the door hinge 1 in the channel 25 and secured by a lock washer 27 against unwanted adjustment. By means of a screwdriver, the valve 26 can be adjusted so that the flow of oil in the channel 25 is increased or decreased.
  • the entire door hinge and thus all previously mentioned pressure chambers 19, 20, 28 cavities 22 and channels 23, 24, 25 are completely filled with oil.
  • the spindle 5 When opening the door, the spindle 5 rotates within the door hinge 1 and moves the spindle nut 11 along the thread 5a, 11a in the direction of pin 6. In this case, the compression spring 12 is compressed and the first pressure chamber 19 is reduced. The oil located in the first pressure chamber 19 is conveyed through the channel 25 into the pressure chamber 28, which increases by the axial movement of the spindle nut 11 below its lower end face. This additional pressure chamber 28 is connected via the channel 24 with the second pressure chamber 20.
  • the compression spring 12 presses the spindle nut 11 down again, so that the spindle 5 rotates.
  • the pressure chamber 28 decreases and the oil flows through the channel 25 back into the first pressure chamber 19, which increases simultaneously.
  • the valve 26 regulates the volume of oil and dampens the closing movement of the door. If, despite the closing damping, the door closes very quickly by force or due to high wind load, the valve 21 can open the flow through the channel 23 and let the oil flow directly from the first pressure chamber 19 into the second pressure chamber 20, from where it then via the channel 24 is passed into the pressure chamber 28.
