Definitions

  • the invention relates to a switching profile in the form of an elastic hollow chamber profile, which has an outer, in cross section through the hollow chamber profile circumferentially closed electrically insulating jacket layer and first and second voltage applied to the inner surface of the jacket layer and connected to the jacket layer electrically conductive contact layers in the unloaded state of Hollow sections are spaced apart and can be brought in a compression of the hollow chamber profile by acting in a main actuation direction release force in contact.
  • Flexible switching profiles or switching strips are used when an electrical pulse that causes a switching operation to be triggered by a pressure on the profile over a greater longitudinal extent at any point.
  • Most such switching profiles are designed in the form of hollow chamber profiles, as for example from the CH 677 546 A5 is known.
  • Such a hollow chamber profile comprises an electrically insulating outer jacket layer and within the same at least two, usually opposing electrically conductive contact layers in which metallic electrical conductors can be embedded, which extend in the longitudinal direction of the hollow chamber profile.
  • the outer contour of the hollow chamber profile usually has a shape that corresponds essentially to a flat oval, ie the short axis of the oval is parallel to the main operating direction of the switching profile.
  • a triggering can also be achieved by a triggering force that is at an angle to the main operating direction, for example, up to an angle of 45 °.
  • a disadvantage of such conventional switching profiles is that they can only be used for a straight or slightly curved course. Tighter arcs around bending axes, which are parallel to the transverse direction, are not possible, since otherwise the contact layers come to rest on each other as a result of the different radii of curvature, in particular if metallic conductors are embedded in the contact layers. Tighter arcs around bending axes or even corners lying parallel to the main operating direction are likewise not possible, since the switching profile forms waves in these cases and thus the contact layers already come to rest against each other without any acting triggering force. Corners must therefore be formed by separate mold corners, which lead to additional costs, difficult to be sealed in the transition areas for switching profile and can be performed switching active only in a complex manner.
  • the object of the invention is to provide a switching profile of the type mentioned with an improved bending behavior. According to the invention, this is achieved by a switching profile with the features of patent claim 1.
  • the inventive construction in particular a greater flexibility around an axis parallel to the main direction of actuation axis can be achieved without this leads to a contact of the contact layers when no triggering force acts, yet sufficient compressibility of the switching profile is present in order to act on a triggering force Contacting the contact layers to achieve.
  • a switching profile according to the invention can even be designed to move around corners, for example window corners of a window to be secured.
  • the predetermined bending points of the jacket layer is also to be achieved that it comes at a biasing force acting obliquely to the main operating direction (up to a predetermined maximum angle) to such a small mutual displacement of the first and second contact layer in the transverse direction that they still meet each other safely.
  • only one predetermined bending point is present in each of the two sections of the jacket layer extending in the region between the first and second contact layers, the two predetermined bending points lying opposite one another and being arranged in the middle between the first and the second contact layer.
  • the torque acting on the foot section can thereby be kept low in the case of a release force acting obliquely to the main actuation direction. If the foot portion is formed as a support foot and is glued to the ground, so here the obliquely acting deformation forces are directed as evenly as possible in the contact surfaces. If the foot portion is formed as anchoring foot and is inserted in a groove, the risk of unscrewing due to obliquely acting deformation forces is significantly reduced.
  • the inner contour of the jacket layer seen in cross section is formed substantially oval, wherein the long axis of this oval is parallel to the main operating direction.
  • the contact layers are each formed sickle-shaped. A formation of compression bumps in bending or bending around a bending or bending axis parallel to the main operating direction can be counteracted in this way.
  • Fig. 1 is a cross section through a first embodiment of a switching profile according to the invention is shown.
  • the shift profile is formed by an elastic and flexible hollow chamber profile 1.

  • the switching profile is advantageously formed in one piece.
  • the electrically insulating jacket layer 2 and the electrically conductive contact layers 5, 6 are preferably coextruded, if appropriate together with the conductors 8, 9 embedded in the contact layers 5, 6.

  • the embedded in the respective contact layer 5, 6 conductor 8, 9 lies in this longitudinal center plane 25th
