Definitions

  • the invention relates to a door closer according to the preambles of claims 1 and 2, in which, on the one hand, there is a cam disc which is connected to an output shaft emerging from a housing filled with a damping medium in a non-positive and positive manner, the cam disc in the axial direction seen the door closer on each side rests on a pressure roller and on the other hand is in operative connection with a spring piston acted upon by a closing spring and on the other hand with a damping piston, the piston and the housing being made of an oil-tight plastic and on the other hand a door closer with a plastic piston having internal teeth , which is driven via a pinion arranged in a non-positive and positive manner on an output shaft, the output shaft emerging at least on one side from a housing surrounding the piston and a closing spring.
  • a generic door closer of claim 1 has become known from the Swiss patent 281 690.
  • the door closer described there can be used for doors hinged on the left and on the right, whereby an existing output shaft is equipped with a symmetrically designed 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.
  • DE G 94 13 039 U1 shows a generic door closer according to the preamble of patent claim 2, where a door closer is described which reproduces an internal toothing in a piston.
  • the toothing and the piston are designed as separate components, the toothing preferably being made of a material other than plastic, from which the piston is made.
  • at least parts of the pinion engaged with the toothing are partially made of metal and plastic.
  • DE 40 02 889 A1 shows a door closer, the housing of which is designed as a hollow chamber profile. This hollow chamber profile is in one piece and consists of an extruded profile, the material of which consists of an aluminum alloy or plastic.
  • a damping piston which is composed of a solid body and an associated elastic body made of rubber or plastic, is described in DE-AS 10 39 886.
  • a piston which shows an external toothing in the form of an inserted rack, which is made of metal or plastic, can be found in US 4,019,222.
  • the object of the invention is to produce a light, inexpensive door closer in which the machining which is usually required can be dispensed with.
  • the cylinder walls surrounding the pistons are usually round. This is due in particular to the reworking that usually takes place, since the round shape is the easiest to accomplish. But if you want to produce an inexpensive small door closer, that is to say a door closer that does not have a large build-up, the cross section of the piston, that is to say the damping piston and the spring piston, can also be produced or also take a cross section of the plastic piston with teeth other than the round one, namely an oval, rectangular, square or square cross section. All of these forms can be manufactured in plastic without any problems in terms of production technology, since such housings or pistons are manufactured using the so-called injection molding process.
  • injection molding process nowadays, due to the available plastics, these processes have an enormous dimensional tolerance and thus a precise fit.
  • plastic for example door closers according to DE 36 45 314 C2 and DE 3645 315 C2, at no additional cost, in which the teeth of the toothing of the piston have different sizes and different modules.
  • the mating toothing of the output shaft, which meshes with this toothing, can also be made of plastic without any problems.
  • Such a housing does not necessarily have to be produced from one part by injection molding because of the geometric cross sections. This is also possible from several segments or sub-segments. On the contrary, these segments or sub-segments are assembled or put together on molded registers or protrusions and corresponding recesses and permanently and forcefully connected to one another by appropriate methods such as gluing, ultrasonic welding, laser welding or the like. The dimensional stability of the individual segments is maintained by this method. At the same time, it is possible in the design in the individual segments of the housing, also channels, bores, pockets, valve seats or even valves directly during the manufacturing process without
  • closure caps or closures which, depending on the segment produced, do not necessarily have to be present in the object according to the invention, since pre-assembly of individual parts is quite conceivable by joining the individual segments closed on one side. On the segments, only afterwards a closure is possible, separate closures are then introduced.
  • closures can also be non-positively and positively connected to the segments or to the housing by adhesive bonding, ultrasonic welding, or the like.
  • closures provided with grooves, undercuts or bayonet closures are also to be used, since this can reduce assembly times when assembling.
  • the fastening devices in the form of corresponding bores in order to mount the door closer in its original place in the finished state, can also be molded without cutting in an injection-molded plastic version.
  • the invention is explained in more detail below on the basis of various schematically illustrated exemplary embodiments. It shows:
  • Figure 1 An axial section through a side view of an overhead door closer with a cam disc.
  • Figure 2 An axial section through a plan view of a
  • Figure 3 A section through an overhead door closer in the
  • FIG. 4 section through a top view of an overhead door closer according to FIG. 3.
  • Figure 5 Section through a housing of a door closer, which consists of individual segments.
  • Figure 6 Side view of two housing halves, consisting of two housing segments with a square cross section of the piston chamber.
  • the door closer shown in Figures 1 and 2 has a cam disc 1, which is penetrated by an output shaft 3.
  • the output shaft 3 is supported in the upper region by an output shaft bearing 17 and in the lower region by an output shaft bearing 16 within a housing 2.
  • the bearing consists of either a sintered material or a nail bearing or ball bearing.
  • the output shaft bearings 16 and 17 can also be made of plastic in addition to the housing 2.
  • the cam tracks of the cam disc 1 come into contact on one side with a pressure roller 7, which is supported via an axis 14 within a damping piston 14.
  • the cam disc 1 is in contact with a pressure roller 8, which is supported via an axis 15 within a spring piston 6.
  • a closing spring 13 comes to bear against the other end of the spring piston 6 at one end and at the other end against a spring counter plate 31.
  • the lateral ends of the housing 2 are closed by closures 18 and 19, which are connected to the housing 2 either positively or positively by gluing, ultrasound welding, laser welding or the like. Since corresponding channels 20 in connection with valves 29 are necessary for the control function of a door closer, these have been molded into the housing 2 without cutting in the manufacturing process.
  • check valves 5 both within the damping piston 4 and in the spring piston 6, check valves 5 have also been molded in during the manufacturing process of these pistons. However, it is also possible to manufacture these check valves 5 separately, in which case they also consist only of plastic.
  • a fastening device 28 In order to fasten such a housing 2 to a door or above the door, a fastening device 28 has been formed without cutting simultaneously with in or on the housing 2 during the manufacturing process. It goes without saying that plastic processing without subsequent processing means that in addition to the continuous cylinder bore for the damping piston 4, the spring piston 6 and the closing spring 13, which are round in the prior art, other shapes are also possible. These are in particular an oval shape, which would also mean that the closer would be considerably narrower in its dimensions or rectangular or square shape.
  • a rack and pinion closer with a piston 10, which is made of plastic and has an internal toothing 11, is shown.
  • a toothed pinion 12 is operatively connected to the toothing 11, the pinion pin 12 being integrally and positively formed on the output shaft 3.
  • the piston 10 with its toothing 11 and the output shaft 3 with its pinion 12 are also made of plastic in this exemplary embodiment.
  • the door closer has the same properties as in FIGS. 1 and 2, that is to say, even with this door closer, heating would not result in failures due to the same expansion coefficients in terms of function.
  • the ends of the housing 9 are also closed by closures 18 and 19, which are likewise connected to the housing 9 in a positive and non-positive manner by adhesive bonding, ultrasonic welding, laser welding or the like.
  • closures 18 and 19 which are likewise connected to the housing 9 in a positive and non-positive manner by adhesive bonding, ultrasonic welding, laser welding or the like.
  • FIG. 5 shows a housing of a door closer, which is composed of different segments 21 and 22. It is possible to carry out different segments individually in terms of production technology, for example segment 22, which has been reproduced as a segment open on one side with integrally formed fastenings 28. At the points to be connected, the segments 21 and 22 have registers 26 and depressions 27 which engage with one another when they are joined together and, in the subsequent method for connecting the segments 21 and 22, assume a non-positive and form-fitting shape which is also dimensionally stable.
  • the piston chamber 30, which is located within the segments 21 and 22, is closed on the open side of the segment 21 by a closure 19.
  • a bore 23 for the output shaft bearing 16 and 17 shown in FIG. 1 is simultaneously formed in the segment 21 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 one another 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 in this exemplary embodiment in FIG. 6.
  • door closers of any kind are involved, which are assembled without subsequent processing of the individual parts and segments.
  • Such an assembly can also be carried out in an automatic process.
  • the parts made of plastic preferably in an injection molding process, are non-positively and positively connected to one another without subsequent processing by gluing, ultrasonic welding, laser welding or the like.
  • Plastic can be a carbon fiber or glass fiber reinforced plastic.
