Definitions

  • the invention relates to an automatic door closer according to the preamble of claim 1 and a method for its assembly.
  • the piston dividing the interior of the housing into two pressure medium spaces is formed in the door closer according to the invention from a coupling part and an outer part.
  • the connection between the coupling part and the outer part is directly connected to the force transmission elements located on the drive axle in a non-positive and positive manner and free of play.
  • GB 2,244,759 A discloses a piston of a door closer which is not directly connected to the axle group.
  • a piston pin is mounted in a generally known manner while penetrating the sealing surfaces of the pistons. This type of connection is not outside the housing to accomplish, but must be carried out within the housing.
  • a door closer which is provided with a force-transmitting piston rod can be found in DE-PS 163 160. There is a piston surface which protrudes from the piston, which means that the axle drive is located far from the piston. Due to this design, the door closer is enormously large in its outer dimensions.
  • EP 0 469 697 A1 reproduces a door closer in which the piston is screwed directly onto a piston rod.
  • the force of the axle drive which is arranged relatively far from the piston, is introduced into the piston via the piston rod. This principle of operation would also not function without the force-transmitting piston rod and thus lengthening the door closer.
  • the object of the invention is to further develop an automatic door closer in which the overall length of the housing is reduced, but at the same time very good hydraulic functions are guaranteed with an increase in the overall efficiency. Furthermore, the manufacturing costs are also to be reduced at the same time.
  • the object is achieved in that the damping piston. that divides the interior of the housing into two rooms, is placed close to the drive axis of the door closer, and thus a direct assembly of a coupling part can be carried out with a tab carriage.
  • the space required for the coupling flange, which is connected to the plate carriage via a pin, is provided in the interior of the piston. This preassembly is carried out outside the housing and is therefore much quicker and less expensive to carry out than conventional piston rod connections.
  • connection in the damping piston consists of a coupling part and an outer part, whereby the outer part is inserted over the pre-assembled coupling part after assembly of the entire axle group, which consists of the drive axle, the cam disc, the plates, the bearings and the rollers with the coupling part .
  • the entire axis group is for final assembly through the housing entry on the top of the door lock. ßers used, whereby the outer part is inserted through a side entry into the housing, and thus simultaneously in the cylinder bore of the door closer.
  • the outer part is inserted over the coupling part, and a non-positive and form-fitting and play-free connection between the two parts by a connecting member
  • the coupling part is designed in such a way that the connection in the form of a pin, which is otherwise present in the outer surface of the piston, is also used in the coupling part, only the outer part covers this area due to its walls and simultaneously secures the pin connection in the Coupling part, so that only the outer part provides a seal within the cylinder wall, the connecting pin occurs, as is the case in the prior art.
  • This pin must be secured by the outer skin of the piston, ie in the area where a seal to the cylinder wall is necessary. This securing is usually achieved by caulking.
  • Another type of fastening can be such that the connecting member is connected to the outer part directly outside the housing or consists of a piece, and this preassembled group is brought together with the preassembled axle group and the coupling part inside the housing however, it is necessary that the outer part with the connecting member is secured with respect to the axle group with the coupling part.
  • a securing can be produced, for example, by a locking ring or by a nut, ie a screw connection
  • valves and channels within the complete piston that allow this, for example a check valve is present which ends with its adjoining channel in a so-called ring channel which is located inside the outer part.
  • the assembly process of such an automatic door closer can e.g. run in such a way that the parts of the axle group which are in the unpressurized space can be completely pre-assembled outside the housing.
  • This means a precise execution of the work because this pre-assembled axis group is then inserted into the housing of the door closer, specifically through the area of the housing cover that has not yet been closed.
  • the outer part is plugged onto the coupling part from the cylinder side of the housing, which will later also be screwed through a sealing cap.
  • the connecting member is connected to the coupling part in a non-positive and positive manner, which also brings about a non-positive and positive connection of the outer part.
  • the compression spring i.e. the lift mechanism is inserted into the housing.
  • Figure 2 shows a longitudinal section through a closer housing with mounted
  • FIG. 3 is a sectional drawing of a piston connection
  • the complete axle group 1 essentially consists of the drive axle 18 with a cam disc 28 connected to it in a force-fitting and form-fitting manner, the tabs 16, 17 for connecting the pressure roller 27 and the support roller 29 via the pins 22. 23.
  • the drive axle 18 is thereby in lower area supported by a bearing 19.
  • a coupling part 15 for the damping device of the automatic door closer is connected to the tabs 16, 17 via a piston pin 14 with the tabs 16, 17.
  • the pins 22, 23 and the piston pin 15 are not caulked because, because of the type of construction, it is not necessary to secure these pins
  • the coupling part 15 is designed so that it has a projection 10 in which there is a bore with an internal thread 11. This internal thread is used to connect the outer part 30 to the coupling part 15. Furthermore, a chamfer 12 has been formed on the coupling part 15, which interacts with an annular channel 13 present within the outer part 30. In the exemplary embodiment in FIG. 1, the flow channels leading from this annular channel 13 to the unpressurized space 31 are not shown
  • the outer part 30 consists essentially of a receptacle 8 for the coupling part with an adjoining ring channel 13. Following the ring channel 13 there is a stepped bore 9 which has the same diameter as the shoulder 10 of the coupling part 15. The stepped hole 9 becomes wider narrowed to the bore 7 If the outer part 30 is plugged onto the coupling part 15, then the outer part 30 is guided in the area of the stepped bore 9 on the coupling part 15 in the area of the extension 10. After the outer part 30 has been put on, a positive and positive connection is made the coupling part 15 is a connecting member 3 which has a threaded shoulder 4. screwed into the internal thread 11 of the coupling part 15. In the screwed-in state, a shoulder 24 of the connecting member 3 is screwed against the piston surface 25 of the outer part 30. In addition to the non-positive and positive connection, this also results in a play-free connection
  • the outer part 30 there is at least one check valve 5 which ends in a channel 6.
  • This channel 6 in turn ends in the ring channel 13 which forms a circumferential channel with the chamfer 12 of the coupling part 15 and has a connection to the unpressurized space 31 By in this way the damping medium can flow from the pressure chamber 32 into the unpressurized chamber 31
  • FIG. 3 Another type of connection is shown in FIG. 3, in which the tabs 16, 17 are likewise connected to one another via the coupling part 39 and the piston pin 14.
  • the coupling part 39 is designed somewhat differently, namely it has an annular channel 36.
  • This annular channel 36 has a connection to the channel 6, which is located inside the outer part 33.
  • the complete axle group 1 can also be preassembled with the coupling part 39 outside the housing 20
  • the outer part 33 has an inner bore in which the connecting element 3 is inserted outside the housing 20, specifically via the connection 38.
  • the connection 38 can be a screw connection, for example.
  • This preassembled group, consisting of connecting element 3 and the outer part 33 is replaced by the Pressure chamber 32 inserted into the housing 20 of the door closer. If the seat is correct, the coupling part 39 and the outer part 33 then lie one above the other.
  • a direct connection must now be made between the axle group 1 inserted through the open area of the housing cover 21 with the coupling part 39 and the pre-assembled connecting part link 3 with the outer part 33 This can be made possible, for example, by a securing pin 35 which is located within a groove 34 which is located in the outer part 33.
  • a screw connection can also be selected which and positive connection between the coupling part and the outer part ask
  • FIG. 2 shows the assembled parts for assembling the automatic Tursch ßt-r.
  • the axle group 1 has been preassembled outside the housing 20 as already described. This axle group 1 is then subsequently in the housing 20 through the opening, which is later through the housing cover 21 is closed, then the outer part 30 is placed over the coupling part 15 by the pressure space 32, which has not yet been filled with the compression spring and the damping medium.
  • the connecting member 3 is then also screwed into the coupling part 15 through the pressure space 32, what at the same time ensures a backlash-free, non-positive and positive connection between the inner and outer part.
