Definitions

  • the invention relates to a door closer according to the preamble of claim 1.
  • a universal door closer of this type has become known from DE-AS 25 35 244.
  • An energy store in the form of a compression spring is located within a housing. This compression spring is supported at one end on a rocker arm and a roller connected to it, the other end being supported against a closure in the outer wall of the housing. There is also a spring force adjustment inside the closure, which is accessible from the outside. The spring force adjustment enables the spring force of the spring accumulator to be infinitely adjusted. If the drive axis of the door closer is rotated due to the connected door, compression of the compression spring will occur at the same time due to the cam disk which is connected to the drive axis in a non-positive and positive manner. As a result of the compression of the compression spring, in addition to the increased pressure of the damping medium, a further additional pressure is exerted on the sealing cover of the housing by the compression spring.
  • Another door closer with adjustable closing force can be found in DE-PS 32 24 300.
  • the structure of this door closer can be seen analogously to DE-OS 25 35 244, likewise, when the door is open, the entire pressure is additionally on the end cover of the door closer housing.
  • the spring force adjustment is made possible by an adjustment device that is accessible from the outside and is implemented using a thread.
  • a further adjustability of the spring force is also possible in the form that it cannot be changed in the assembled state, but must be adjusted according to the size of the door closer during assembly.
  • the compression springs are here guided by a guide guiding and power transmission element or power support element, an adjustment device being located at one end of this guide means, which allows the spring force to be adjusted continuously.
  • the damping piston which is also required for the closing process of the connected door is located next to the ones shown Kraftspei ⁇ or in US 4,064,589 flanged as an additional element outside the space occupied by the compression spring.
  • GB 2,244,759 A discloses a door closer in which spring adjustment is possible from outside the spring. This has the consequence that the outer dimensions of the door closer become larger because the adjusting sleeve is behind the spring of the door closer.
  • the object of the invention is to create a door closer with small geometn- see housing dimensions, but also with a very high efficiency, at the same time the closing force is adjustable, and the pressure distributions on the housing walls are reduced and optimized
  • the object of the invention is achieved in that the compression spring is supported on the one hand within the housing and the spring force adjustment on the other side forms the counter bearing.
  • the spring force adjustment lies within the spring in a spring actuating sleeve. which has no fixed connection, ie there is only a positive connection with the adjustment device located outside the housing.
  • the spring adjustment lies within the pressure chamber.
  • the entire adjusting device moves with the opening of the connected door leaf. ie the piston is pulled by the selected construction, namely piston with a compression spring. Due to the power transmission element There is a tensile force on the piston when the door is opened. This results in a straight guidance of the piston, which avoids tilting of the piston, which has been placed at a relatively close distance from the drive axis with the cam disc located thereon following the compression spring.
  • the spring force adjustment is realized in that a device has been created. which is implemented by an adjusting sleeve, which is located within the space surrounded by the compression spring.
  • This adjusting sleeve has a cavity, in the bottom of which a connection is established between the force transmission members, namely the plate carriage and the connecting member. Via this connection, the spring force is adjusted at the same time, which can be done for the assembly directly in the non-installed state, or realized in the installed state in such a way that there is a cavity within the spring adjustment sleeve, in which a cavity is located immersed in the locking cap.
  • the power transmission between the driver of the adjusting device and the adjusting sleeve is achieved by positive locking.
  • This can for example may be a hexagon or any other geometrical shape, the shape of the driver in particular being incorporated accordingly into the opening of the adjusting sleeve.
  • FIG. 2 shows, in a sectional view from above, essentially the arrangement of a compression spring 1 of a piston 19 and a cam cam 17 within a housing 18.
  • the cam cam 17 is arranged on a drive axis 24 of the door closer in a non-positive and positive manner a pressure roller 30 and a support roller 28, which are fastened in a tab carriage 31, are simultaneously guided.
  • the piston 19 is also attached to the tab carriage 31.
  • a connecting member 20 for receiving an adjusting screw 23 is provided. This connecting member 20 plunges into the interior of the compression spring 1, and is thus completely enclosed by it.
  • the compression spring 1 is placed inside the housing 18 in such a way that it is supported at one end by a protrusion 21 with a support disk 4 in between, approximately in the middle of the housing , wherein the other free end is directed towards a support disk 6 through the support disk 6 t an adjustment sleeve 2 passes through, which also projects into the interior of the compression spring 1.
  • the adjustment sleeve 2 is constructed in such a way that it has a projecting collar 5 which is supported on the support disk 6
  • the adjusting sleeve 2 is further designed so that a cavity 8 is present in its inner region.
  • a breakthrough 11 which enables a geometrical shape designed in accordance with the driver 12 for the positive connection between the driver 12 and the adjusting sleeve 2.
  • the driver 12 plunges into the cavity 8 of the adjusting sleeve 2 through the opening 11 in accordance with the direction of movement 16.
  • the driver 12 is also surrounded by the compression spring 1, so that the driver is placed in the interior of the compression spring 1. This means that the adjustment mechanism does not enlarge the door closer.
  • the opening 11 is kept somewhat smaller in terms of the geometric dimensions, so that the driver 12 virtually only enters into a positive connection with the adjusting sleeve 2 in the area of the opening 11.
  • the adjusting screw 23 In the bottom 9 of the adjusting sleeve 2 there is a thread 10, which for spring force adjustment in connection with the adjusting screw 23 brings about a spring force adjustment by actuating the thread.
  • the adjusting screw 23 is preferably in a non-positive and positive engagement with the connecting member 20.
  • a counter bearing and thus a stop for unintentionally unscrewing the spring force adjustment 23 forms the locking washer 22.
  • the spring adjustment path 32 is used for spring adjustment and thus corresponding force adjustment can be.
  • the maximum possible spring adjustment path 32 has been used.
  • the driver 12 is placed inside the closure cap 3 via a seal 25 and for securing purposes via a locking washer 26.
  • the end of the driver 12 protruding from the sealing cap 3. namely the adjusting screw 13 is accessible with an appropriate tool.
  • the closure cap 3 is screwed into the housing 18 via a thread 14.
  • a seal is achieved by the seal 15.
  • the protruding driver 12 is simultaneously introduced into the adjusting sleeve through the opening 11 in such a way that there are no enlargements beyond the driver cross section.
  • the driver 12 is completely housed inside the adjusting sleeve 2.
  • the driver 12 is provided with a hexagon, which means that the same shape of the sea edge is also present in the opening 11.
  • any other form which is capable of transmitting the corresponding forces for adjusting the compression spring 1 when the adjusting screw 13 is actuated.
  • the compression spring 1 is shown in the decompressed state.
  • the driver 12 is completely immersed into the cavity 8 within the adjusting sleeve 2, in contrast to the prior art, in which the drivers are behind the adjusting device and thus result in an extension of the door closer .
  • the compression spring 1 has been set with maximum spring preload and at the same time the door has been pivoted through 180 °, which results in maximum compression of the compression spring 1. In this extreme position, it must also be ensured that the driver 12 continues to immerse in the opening 11 of the adjusting sleeve 2. This type of device makes it clear that there is no fixed connection between the spring adjustment and the connecting member 20.
  • the entire adjusting screw 23 is also moved when the drive shaft 24 is actuated, ie it is pulled, which at the same time represents better guidance for the piston 19 (damping device).
  • This type of construction makes it clear that additional compressive forces act on the Cap 3 are not exercised as is the case with the known prior art.
  • the entire pressure distribution has been aligned to a very narrow space, namely towards the middle of the housing. This type of construction makes it possible to keep the geometrical dimensions of the housing within very narrow limits. There is also no additional sealing of an otherwise normally existing piston rod necessary, since the entire device of the spring adjustment device is located within the pressure chamber in the subject invention.
