Definitions

  • the present invention relates to a folding door with a plurality of wing pairs, the wings of each wing pair being articulated to one another and each two adjacent wing pairs being hinged to a common support device and at least the support device or the support devices being guided at least along a horizontal guide rail and that and in each case a driver is connected to at least one wing located in the hinge area.
  • a folding door of the generic type is known from DE-A-1759226
  • the first pair of wings which a user intends to open, can usually be manipulated the required torque can be applied.
  • the adjoining pairs of wings are coupled to one another via a gear mechanism, the gear mechanisms causing a synchronous opening and closing movement.
  • the present invention has for its object to provide a folding door of the generic type, in which an inexpensive to manufacture and space-saving opening aid is realized when opening all pairs of wings.
  • a two-armed lever is connected to the common support device which can be pivoted about an axis of rotation parallel to the hinge axis, one of which lever arm lies in the pivoting range of the driver and the other of which lever arm extends into the area of the wing which corresponds to the with the driver equipped wing is adjacent, so that from a certain pivoting angle of the wing equipped with the driver, a torque acting in the opening direction is exerted on the adjacent wing via the two-armed lever.
  • an opening aid according to the invention is simply constructed, consists of only a few individual parts and, due to the fact that the two-armed lever about a parallel to the hinge axis extending axis of rotation is pivotable, the opening aid according to the invention is also extremely space-saving, which is of particular importance in the case of folding doors for cupboards.
  • the folding door 1 shown in Figure 1 has two pairs of wings 2 and 3, wherein the wings 2a and 3a of each pair of wings 2 and 3 are hinged together, which is illustrated by indicated hinges 4.
  • the two adjacent wing pairs 2 and 3 are hinged to a common support device 5 and this support device 5 is guided in a known manner along a horizontally extending guide rail 6.
  • the outer wings 2a and 3a in FIG. 1 are also also displaceably guided in the guide rail 6.
  • the basic idea of the present invention is not causally related to whether the folding door 1 can be opened on both sides or whether one of the end wings 2a or 3a is fixed with respect to the guide rail 1. In the latter case, the folding door 1 would then only be able to be opened to the right or to the left
  • the problem with which the present invention is concerned is that when a folding door 1 is opened, a torque must be exerted on the wings 2a and 3a of the two wing pairs 2 and 3, which causes the wings 2a and 3a snap out of its closed position while rotating around the hinges 4.
  • the aim is to be able to apply such a torque to the pair of wings 2 or 3 following in the opening direction, so to speak, so that this pair of blades can also be applied automatically 2 or 3 is buckled or folded out of its closed position.
  • a driver 7 is fastened to each of the two wings 2a and 3a lying in the hinge area of two adjacent pairs of wings 2 and 3, and two two-armed levers 8 are arranged on the common support device 5, each by one Axis of rotation 9 running parallel to the hinge axis and each of which a lever arm 8a lies in the pivoting range of the associated driver 7 and the other lever arm 8b of which extends into the area of the wing 2a or 3a which corresponds to the wing 2a equipped with the driver 7 or 3a is adjacent.
  • FIGS. 3 and 4 make it clear that when a pair of wings is opened - in the illustrated embodiment of the pair of wings 3 - the driver 7 attached to the wing 3a exerts a torque on the associated two-armed lever 8 from a certain pivoting range of the wing 3a in question because of this that the driver 7 acts on the lever arm 8a.
  • the corresponding force is transmitted to the adjacent wing 2a via the second lever arm 8b and there causes a torque to be exerted on this wing 2a, which causes the subsequent wing pair 2 to buckle to facilitate the opening movement of this subsequent wing pair 2 as well.
  • the correspondingly assigned two-armed lever 8 would be actuated via the driver 7 attached to the wing 2a, the lever arm 8b of which in this case would act on the adjacent wing 3a in the sense of buckling.
  • the arrangement of two drivers 7 and two levers 8 is required when the folding door - as shown in the embodiment - can be opened on both sides.
  • FIG. 2 makes it clear that the levers 8 are connected to a support device 5 designed as a hinge support.
  • This is a known and therefore not further described support device 5 in the form of an approximately U-shaped bracket 10, which serves on the one hand as a hinge support and on the other hand as a roller support.
  • the opening aid described above is extremely space-saving, which in particular It is of great advantage if the space behind such a folding door 1 is to be used as optimally as possible, for example in a cupboard.
  • the opening aid ultimately only consists of simple components, it is also simple and inexpensive to manufacture.
  • the drivers 7 and the lever arms 8b are equipped with sliding rollers 11.
  • FIG. 5 to 7 make it clear that even with support devices 5 in the form of hinge brackets with double hinges - especially again for heavy wings 2a and 3a - the driver 7 and the lever 8 in the area between the hinges 12 can be arranged to save space.
  • levers 8 can be mounted in corresponding recesses in these pilaster strips without any problems.
  • the attachment of the driver 7 and the lever 8 is unproblematic in terms of assembly, in particular it is conceivable to retrofit existing folding doors with opening aids designed in this way.
  • Both the driver 7 and the lever 8 are preferably made of plastic. The same applies to the sliding rollers 11.
  • lever 8 and the driver 7 it can be determined from which opening angle the desired opening aid comes into force.
  • appropriate dimensioning of the lever 8 can ensure that the torque exerted on the following leaf is sufficiently large in the sense of the desired opening aid.
