Definitions

  • the invention relates to a door closer according to the preamble of claim 1, in which a Hubkurvenin is present, which is non-positively and positively connected to a discharged from a filled with a damping medium housing output shaft, the Hubkurvenin seen in the axial direction of the door closer on each side abutting on a respective pinch roller and on the other hand is in operative connection with a spring loaded with a closing spring and on the other hand with a damping piston, wherein the piston and the housing are made of an oil-tight plastic.
  • a generic door closer has become known from Swiss patent specification 281 690.
  • the door closer described therein is suitable for DIN left and DIN right hinged doors, with an existing output shaft is equipped with a symmetrically shaped cam, which is in contact with the piston and thus with the closing spring.
  • Both the housing and the piston are made of an oil-tight plastic.
  • FIG. 1 Another door closer is shown in GB 2 292 182 A, where a door closer is described, which reproduces an internal toothing present in a piston.
  • the toothing and the piston are designed as separate components, wherein preferably the toothing of a material other than plastic, from which the piston is made, is made.
  • the housing and the housing closing plug made of plastic.
  • the object of the invention is to produce a lightweight, cost-effective door closer, in which the usually resulting machining can be omitted.
  • the cylinder walls surrounding the pistons are round. This is particularly due to the otherwise occurring rework, since the round shape is the easiest to accomplish. But if you want a cheap small door closer, ie a Mosschlie-ßer that does not build up strong, can also cross section of the piston, ie the damping piston and the spring piston or even the plastic piston with teeth take a different cross-section than the round, namely an oval, rectangular, square or square cross section. All of these forms can be produced without problems in plastic, since such housings or pistons are manufactured in the so-called injection molding process. These methods have today due to the available plastics an enormous dimensional tolerance and thus fit on.
  • such a housing does not necessarily have to be produced from one part by injection molding. This is also possible from several segments or subsegments. These segments or sub-segments are put together on integrally formed Passer or projections and matching recesses on the contrary or placed together and connected by appropriate methods, such as gluing, ultrasonic welding, laser welding or the like, non-positively and positively permanently. By these methods, the dimensional stability of the individual segments is obtained. At the same time it is possible in the design in the individual segments in the housing, even channels, holes, pockets, valve seat or even valves directly during the manufacturing process, without rework, with or on. As a result, the installation effort and thus the manufacturing cost factor is reduced.
  • caps or closures these need not necessarily be present depending on manufactured segment in the subject invention, since the joining of the individual closed-sided segments pre-assembly of individual parts is quite conceivable. Separate closures are then inserted on the segments where it is only possible to close them afterwards.
  • closures can be non-positively and positively connected by gluing, ultrasonic welding or the like non-positively and positively with the segments or with the housing.
  • closures provided with grooves, undercuts or bayonet closures in order to reduce assembly times during assembly.
  • the fastening devices in the form of corresponding holes to mount the door closer in the finished state at its original place, can be formed without cutting in plastic injection molding in the same time.
  • the illustrated in Figures 1 and 2 door closer has a Hubkurvenance 1, which is penetrated by an output shaft 3.
  • the output shaft 3 is mounted in the upper region by a output shaft bearing 17 and in the lower region by a Abtriebsachsenlagerung 16 within a housing 2.
  • the bearing consists of either a sintered material or a nail bearing or ball bearings.
  • the output shaft bearings 16 and 17 may also be made of plastic next to the housing 2.
  • the cam tracks of Hubkurvenance 1 come on the one hand with a pinch roller 7, which is mounted on an axis 14 within a damping piston 14 in contact.
  • the Hubkurvenin with a pinch roller 8, which is mounted on an axis 15 within a spring piston 6, in contact.
  • a closing spring 13 at one end and the other against a spring counter-plate 31 to the plant.
  • the lateral ends of the housing 2 are closed by closures 18 and 19, which are connected by means of gluing, ultrasonic welding, laser welding or the like with the housing 2 non-positively and positively. Since for the control function of a door closer corresponding channels 20 in conjunction with valves 29 are necessary, they have been simultaneously formed without cutting in the manufacturing process in the housing 2.
  • Both inside the damping piston 4 as well as in the spring piston 6 check valves 5 are also molded in addition during the manufacturing process of this piston. However, it is also possible to produce these check valves 5 separately, and in such a case they also consist only of plastic.
  • a fastening device 28 has been simultaneously formed without cutting in or on the housing 2 during the manufacturing process.
  • a rack and pinion door closer is shown with a piston 10 made of plastic and having internal teeth 11. With the teeth 11 is a pinion 12 in operative connection, wherein the pinion 12 is formed on the output shaft 3 non-positively and positively with.
  • the piston 10 with its toothing 11 and the output shaft 3 with its pinion 12 are also made of plastic in this embodiment.
  • the door closer has the same characteristics of Figures 1 and 2, d. H. Even with this door closer heating due to the same expansion coefficients would bring with respect to the function no failures.
  • the ends of the housing 9 are also by closures 18 and 19, which are also connected by gluing, ultrasonic welding, laser welding or the like non-positively and positively connected to the housing 9, closed.
  • FIG. 5 shows a housing of a door closer, which is composed of different segments 21 and 22. It is possible to perform different segments manufacturing technology individually, such as the segment 22, which has been shown as unilaterally open segment with molded fasteners 28. At the points to be joined, the segments 21 and 22 have passer 26 and recesses 27, which engage in the joining together and enter into a subsequent positive and positive locking and beyond dimensionally stable shape in the subsequent process for connecting the segments 21 and 22.
  • the piston chamber 30, which is located within the segments 21 and 22, is on the open side of the segment 21 is closed by a closure 19.
  • a bore 23 for the reproduced in the figure 1 output shaft bearings 16 and 17 is also formed without cutting.
  • segments 21 and 22 are also possible to divide the segments in a different form, as shown in FIG. 6.
  • segments 24 and 25 are shown, which are connected to each other in the longitudinal direction of the door closer via register 26 and recesses 27.
  • the piston chamber 30 has been reproduced as a square piston chamber.
