Definitions

  • the following invention relates to a locking device for locking a door leaf in a locking position between an open position and a closed position, wherein the door wing by means of a sliding member which engages longitudinally displaceable in a guide rail, between the open position and the closed position is movable feasible. Furthermore, the invention relates to a guide rail for guiding a door leaf between an open position and a closed position, comprising at least one corresponding locking device.
  • Locking devices for door wings are known in principle. Some locking devices are placed directly in a guide rail in which a slider is longitudinally slidably received to determine the movement of the door leaf between an open position and a closed position. Such a locking device is, for example, from the DE 196 96 294 C1 known, which can be brought by means of an electromagnet with an armature into operative connection with the sliding member to hold the slider. It has proved to be a disadvantage that the locking device is not traversable. Furthermore, it is disadvantageous that only one position of the door leaf is thus detectable. Furthermore, it is disadvantageous that the locking device fully occupies the guide rail in cross section. If, for example, the door leaf has been fixed in a locking position between an open position and a closed position, it can not be moved further into the outermost open position. When transporting bulky objects, for example when moving, this can lead to difficulties.

  • the plunger 16 can be acted upon resiliently with a release force L to facilitate release of the armature 12 from the electromagnet 11 during transfer of the electromagnet 11 from the operating state 1 in the rest state 2 against a residual magnetization in the armature 12.
  • a fast switching of the locking device 10 can be made possible.
  • FIG. 9 shows yet another embodiment of a locking device 10 with an electromagnet 11 having a coil 17, whose turns are arranged about a vertical axis z of the electromagnet 11 and the guide rail 200.
  • a holding force F is generated, which extends perpendicular to the extension direction x of the electromagnet 11 and the guide rail 200.
  • the armature 12 may be disposed below the electromagnet 11.
  • the armature 12 may have a planar body A, which may be arranged parallel to the longitudinal extension direction x of the electromagnet 11 or the guide rail 200.
  • the holding force F of the electromagnet 11 with windings about its vertical axis z can provide a frictional connection for the armature 12.
  • the frictional engagement can exert a reliable holding force F on the armature 12.
  • a holding force F can be provided without magnetization.
  • FIG. 10 Yet another embodiment of the invention, according to which the electromagnet 11 as a rotor of a linear motor may be formed to actively control the movement of the armature 12.
  • the electromagnet 11 and the armature 12 move together.
  • the position of the armature 12 can be variably and steplessly adjusted in both directions together with the position of the electromagnet 11.
  • a continuously adjustable holding force F can be realized.
  • the capabilities of the locking device 10 can be extended.
  • FIG. 11 finally shows a door system with a door 100, which is pivotally mounted on a door frame 101.
  • a guide rail 200 for guiding the door leaf 100 between an open position III and a closed position I can be arranged, comprising at least one locking device 10 for locking the door leaf 100 in a locked position II between the open position III and the closed position I, as above based on the FIGS. 1a to 10 may be formed described.
  • FIGS. 1 to 11 describes the present invention solely in the context of examples.
  • individual features of the embodiments, insofar as it is technically feasible, can be freely combined with one another without departing from the scope of the invention.
