Definitions

  • the invention relates to a contrast surface for making the installation location of an installed EMERGENCY STOP command device visible with a mushroom as a handle, which in the installed state is surrounded in the rear area by the contrast surface.
  • Contrast surfaces of the type mentioned above are known in practice and have proven themselves for use in bright rooms. Difficulties arise, however, in making the installation location visible in dark rooms, since according to the standard regulations (see VDE 0113, Part 1 / 8.2.5) the mushroom must not be self-illuminating and must not be designed as a illuminated pushbutton. This provision is intended to prevent the operating personnel from accidentally concluding from the lighting of the mushroom on the switching status of the EMERGENCY STOP command device. This error could not be ruled out if the contrast surface including the control device were illuminated from the front.
  • the invention has for its object to provide a contrast surface to make the installation location of the EMERGENCY STOP command device visible in dark rooms, without the mushroom being illuminated or being self-illuminating, since the mushroom according to the German standard VDE 0113 part 1 / 8.2.5 must not be designed as a illuminated pushbutton.
  • the contrast surface is provided with lighting elements which shine after the supply of energy. It is advantageous if the lighting elements are realized as first parts made of light-collecting material and if they are illuminated by optical feeding in the rear area of the mushroom. This represents a safe and reliable embodiment, since it is less prone to repair Find components used.
  • the rosette which is present anyway, is used advantageously for a further purpose.
  • the rosette is partially made of light-conducting material, the light can be guided to the first parts of light-collecting material in a simple manner.
  • at least one light guide is provided for the optical supply, which is partially guided in the rosette of the EMERGENCY STOP command device.
  • the rosette itself is advantageously used as a holding device for the light guide, with which the light can be directed and bundled to the first parts made of light-collecting material.
  • a reflector is provided on the EMERGENCY STOP command device, by means of which the contrast surface can be illuminated in the installed state, this makes it possible to redirect light components that otherwise radiate unused to second parts made of reflective material. Due to the better utilization of the amount of light, the light source can therefore be dimensioned accordingly small.
  • a further expedient embodiment exists if light-emitting diodes are provided as light elements on the contrast surface, since these are small and accordingly take up little space and have proven themselves as reliable light sources for illumination.
  • electrical connecting lines are partially guided in the rosette to supply power to the light-emitting diodes.
  • the rosette not only guides the connection lines, but in particular also holds and protects them, so that a safe and reliable power supply can be achieved with them. It also proves to be advantageous if the light-emitting elements are partly made of first parts made of light-collecting material and partly made of light-emitting diodes, since self-illuminating and illuminated light-emitting elements coexist in one unit and there is no need for an additional optical supply.
  • the contrast surface according to claim 10 also enables visualization the position of the EMERGENCY STOP command device if there is radiation outside visible light, e.g. infrared or ultraviolet light.
  • a contrast surface 1 made of first parts 4 made of light-collecting material is attached to an add-on wall 10 to which an EMERGENCY STOP command device 2 with a mushroom 3 and a rosette 6 is attached in the center of the contrast surface 1.
  • the first parts 4 are optically supplied with light-collecting material, which can be carried out, for example, according to FIG. 1 via a hole in the add-on wall 10 on the rear, the first parts 4 shine.
  • the contrast surface 1 made of parts (11) can be long persistent material exist (Fig. 1 left half).
  • the long afterglow material is, for example, a plastic based on polyethylene or polypropylene with fluorescent substances.
  • part of the rosette 6 of the EMERGENCY STOP command device 2 is made of light-conducting material, from which light is emitted directly or via a reflector 7 onto the contrast surface 1 from second parts 9 made of reflective material becomes.
  • this light guide it is of course also possible to use light guides that are partially guided in the rosette 6 for mechanical protection and as a hold.
  • a contrast surface 1 with light-emitting diodes 5 is shown, which are fed via electrical connection lines 8, the electrical connection lines 8 being at least partially mechanically protected in the rosette 6.
  • contrast surface 1 When realizing the contrast surface 1 from second parts made of reflective material, e.g. Infrared or ultraviolet light is reflected.
  • reflective material e.g. Infrared or ultraviolet light
