Definitions

  • the invention relates to a concealed door hinge according to the preamble of claim 1.
  • Such concealed door hinges are well known. They are used to create a connection between a door leaf and a stationary door frame in such a way that they are not visible when closed, which conveys a special value from a design perspective.
  • a concealed door hinge is available, for example DE 10 2005 051 918 A1 disclosed.
  • this concealed door hinge does not meet the requirements insofar as the closing force to be applied by the compression spring is not sufficient, especially in the closed end position of the door leaf, to bring a lock tongue on the door leaf side into engagement with an opening on the door frame side. This means that it is not guaranteed to bring the door leaf into the closed position without manual pressure.
  • the invention is based on the object of further developing a concealed door hinge of the generic type in such a way that the functionality of the locking device is improved and can be implemented with little design and manufacturing effort.
  • the design according to the invention results in a whole series of advantages over the prior art.
  • the locking device can be manufactured with a small number of simple components, which takes into account the constant demands for cost optimization.
  • the invention also results in remarkable functional advantages. For example, only the closing movement of the door is dampened, while there is no damping when the door is opened, the door being closed by at least one spring that is tensioned when it is opened, in such a way that the door is pulled into the door frame and a lock tongue of the door lock can snap into place.
  • the preload of the spring is adjustable so that the closing force can be adapted to the respective conditions.
  • a stop is attached to the pull rod at a distance downstream of the fluid-open blocking element and a closure disk is slidably guided on the pull rod in the gap formed.
  • the locking disk While when the door is opened, the locking disk rests against the stop and is positioned at a distance from the locking element, so that the openings of the locking element are completely open to the fluid passage, when the door is closed, caused by the resistance of the fluid, the locking disk is pressed against the locking element and thus closing part of the fluid opening of the blocking element.
  • the blocking element initially lies tightly against the wall of the fluid chamber until the opening angle of the door reaches, for example, approximately 20° and then the damping is greatly reduced in that the blocking element no longer lies sealingly against the wall, at least in a partial area, that is, the fluid resistance on the blocking element is reduced.
  • the cross section of the fluid chamber is enlarged in the closing direction of the door, which can be done by different shapes. Due to the minimized damping, the spring force now comes into effect, with which the door is pressed into the closed position.
  • FIG 1 is a concealed door hinge for pivotally holding a door leaf on a door frame, with a multi-axis joint 2 having articulated fingers 3, which connects two housings 1 to one another, with a first housing 1, which is in the Figure 1 can be seen on the right side, can be inserted into the narrow side of the door leaf and the branch housing 1 can be inserted into the door frame.
  • the Figure 1 represents a position of the concealed door hinge as it appears when the door is open.
  • a locking device 6 is connected to the first housing 1, which, in particular Figure 2 reproduces very clearly, has a fluid chamber 8.
  • a pull rod 5 is guided through the fluid chamber 8 and is fastened on the one hand to the articulated fingers 3 which can be pivoted relative to the first housing 1 and on the other hand to a holding plate 9 which is positioned on the side of the locking device 6 opposite the housing 1.
  • a holding element 4 connected to it is provided.
  • the pull rod can be axially displaced under spring loading by two compression springs 7 arranged parallel and at a distance from one another, which are supported both on the locking device 6 and on the holding plate 9.
  • the pretension of the compression springs 7 can be adjusted via corresponding adjusting elements 18, which are supported on the holding plate 9.
  • a fluid-open blocking element is arranged in the fluid chamber 8, which is held stationary on the pull rod 5 and which, depending on the displacement position of the pull rod, by means of a seal 13 lies tightly against the wall of the fluid chamber, such as in the Figures 3 and 6 recognizable.
  • a closure disk 15 is slidably provided on the pull rod 5, which, depending on the position of the locking element 10, closes part of the fluid openings 11, 12, the closure disk 15 then being on the stop 14 facing side of the locking element 10 rests.
  • the fluid chamber has two chamber regions 16, 17, with a first chamber region 16 preferably being cylindrical, but at least having walls running axially parallel to the pull rod 5.
  • the second chamber area 17, is designed to be conical, starting from the first chamber area 16, and widening in the closing direction of the door.
  • a position of the locking element 10 can be seen as it occurs when the door is opened.
  • the fluid can pass through the fluid openings 11, 12 as well as through the exposed area between the blocking element 10 and the wall of the conical chamber area 17 flow, so that the pull rod 5 is displaced exclusively against the spring force of the compression springs 7 in the direction of the arrow, the flow direction of the fluid being indicated by arrows.
  • the blocking element enters the first cylindrical chamber region 16, whereby the fluid can also flow through the fluid openings 11, 12 without hindrance.
  • the blocking element lies close to the wall of the first chamber region 16.
  • closure disk closes the fluid opening 12, so that only fluid can flow through the exposed fluid opening 11, which results in a damping of the closing movement.
  • the blocking element 10 reaches the second, conical chamber region 17, with the blocking element 10 being exposed relative to the wall of the second chamber region 17, so that the damping is reduced by the decreasing fluid resistance and only the force of the compression springs 7 ensures the closure of the door causes.
  • the angle of inclination ⁇ , as well as the axial length L of the second chamber region 17, can be freely selected and adjusted depending on the desired opening angle of the door at which the damping is to be reduced.
  • FIG. 6 Another embodiment of the fluid chamber 8 is in the Figures 6 and 7 shown.
  • the second chamber region 17 is not designed to be rotationally symmetrical, but rather as a groove, as is particularly clear in the Figure 7 recognizable.
  • the position positions of the locking element 10, as shown in the Figures 8a) to 8d ) can be identified correspond to those of the Figures 5a) to 5d ), whereby only in one at the end of the closing process Figure 8d ) and at the beginning of the opening process, the blocking element 10 is only exposed to the wall of the groove, so that the fluid, which otherwise consists of a suitable liquid, preferably an oil, can flow freely in this area.
  • a suitable liquid preferably an oil
