Definitions

  • the invention relates to a cap, in particular a key cap, for a control element, in particular a button, for example for use in a motor vehicle.
  • the cap has a cap body and a lighting or projection surface arranged in the cover body, which is visible in the intended use and arrangement of the cap as part of an operating element for the operator due to a light source arranged under the cover.
  • the lighting or projection surface is used to display a luminous symbol that informs the operator, for example, which device can be operated with the operating element, for example, the heater in a vehicle.
  • the lighting or projection surface can be used to inform about the switching state of the control element or the switching state of the devices connected to the control device or it can serve to inform about associated with the control element states of the devices, such as a fault to indicate the device connected to the operating element.
  • control element cap with a lighting or projection surface for the purposes mentioned above.
  • lighting or projection surfaces made of translucent, diffuse plastic are embedded in the control panel covers, which are designed according to the desired symbol, and are visible to an operator when illuminated by a correspondingly arranged light source.
  • These have some disadvantages, in particular if another important information is to be reproduced with the condition whether or not the illumination or projection surface is illuminated.
  • the symbol in the known control caps usually in daylight, especially in direct Sunlight, already clearly visible, and thus the operator can not see the difference in this lighting, whether the symbol is actually lit or not, that is, for example, whether the device connected to the control element is turned on or not or if there is a fault or not.
  • the control element cap according to the invention is intended for the covering and / or actuation of a switch of an associated operating element.
  • the cap forms at least with the switch, the associated control.
  • the cap is integrated, for example, in a control panel or dashboard of a motor vehicle.
  • the associated switch is a push button switch, rotary switch, etc.
  • a lighting or projection surface is configured in the cap body in such a way that by irradiation by a light source arranged on the switch side an icon, for example a font or a pictogram, displayed on the illuminated or on the projection surface, for an operator of the control element, for example the driver , becomes visible.
  • the cap according to the invention is characterized in that the luminous or projection surface comprises a film.
  • This film includes a transparent substrate, a plurality of refractive globules bonded in optical contact with the substrate, an opaque matrix surrounding the beads, and optionally including a diffuser for diffusing light.
  • the light originating from the light source of the control element passes through the refractive globules, the substrate and, if present, the diffuser.
  • the beads are glass beads having a diameter of about 60 microns and a refractive index of about 1.5
  • the substrate is a transparent polymeric material
  • the opaque matrix is a bindered and colored polymeric material layer into which the beads are embedded.
  • the beads act as lenses to collect the light projected from the light source onto the film.
  • the diffuser or the diffuser layer has optical advantages in particular when the symbol is projected onto the slide, and the non-transparent Diffuser layer that, viewed from the operator, the bead structure is not visible.
  • the diffuser may be created by roughening or roughening the substrate; the diffuser layer are provided of an optically inhomogeneous material.
  • the symbol Due to the increase in intensity of the symbol generated by the switch-side light source caused by the film, the symbol can be clearly seen, even with very high ambient light intensity.
  • the increase in intensity but also an increase in the emission area attributable to the beads allows a reliable recognition of the luminous symbol even at an unfavorable viewing angle.
  • the difference between the illuminated and non-illuminated symbol can be seen particularly clearly even under particularly high ambient light intensity. Since the operator can reliably recognize this difference, misinformation of the operator can be advantageously avoided.
  • the foil is preferably the Vikuiti ® XRVS-film which is manufactured by 3M Corporation, and is disclosed in EP 0974072 B1 which hereby is incorporated by reference.
  • the symbol is projected onto the projection surface in one embodiment.
  • the luminous area is provided with a mask representing the symbol.
  • the mask is a diaphragm with a light passage opening whose shape corresponds to the shape of the symbol to be displayed.
  • a mask cap according to the invention can be made particularly inexpensive. By applying the mask directly to the luminous surface a particularly sharp contoured representation of the symbol is achieved.
  • the diffuser layer or the diffuser is not necessarily required and the film without diffuser or diffuser layer is cheaper in comparison.
  • the mask is produced by means of an opaque lacquer layer, which is removed in sections, for example by means of laser processing.
  • the cap according to the invention can be produced particularly inexpensively. Due to the very flexible processing options by the laser, any symbols can be displayed on the cap.
  • the cap body is designed to be transparent or transilluminous at least in the area of the illumination or projection surface, preferably the entire cap body, furthermore the mask is arranged on the inside of the cap facing the switch and adjacent thereto and between the mask and the light source, the film is arranged.
  • the control element cap according to the invention can be produced comparatively inexpensively.
  • the cap body or the lighting or projection surface can be colored to give the symbol shown a desired color. Even with a merely radiopaque and therefore scattering cap body, the diffuser layer or the diffuser is not absolutely necessary and the film without diffuser or diffuser layer is cheaper in comparison.
  • a transparent or translucent lacquer layer is applied to the mask and the film adjoins the transparent or translucent lacquer layer and is glued, for example by means of a pressure-sensitive adhesive. Due to the transparent or translucent lacquer layer, that is to say by their distribution after application and before curing, a comparatively smooth surface is produced despite the opening or depressions provided in the mask in the form of a symbol and the unevenness associated therewith. This facilitates the application of the film and thus the production of the control cap.
  • the film is with the facing the balls coated side of the substrate of the light source of the control element.
  • the invention further relates to an operating element which comprises the previously described control element cap in the previously described embodiments and with the respective advantages described.
  • the operating element is, for example, a rotary switch.
  • the control element is preferably a push-button switch and, in the case of the control-element cap, a push-button cap.
  • control element described above is not least due to the very widely varying light conditions particularly advantageous use in a motor vehicle, where it is integrated, for example, in a dashboard or a control panel.
  • the invention further relates to a method for producing a control cap in one of the previously described embodiments.
  • the transparent or translucent cover body made of polycarbonate, such as Lexan ® manufactured in an injection molding or deep-drawing process.
  • the laser-editable, opaque lacquer on the switch, or the light source the control element facing the inside of the cap body is applied.
  • the opaque lacquer for producing the mask representing the symbol is processed with the laser to produce a mask. Except for the opening of the mask, the inside, ie the light source or the switch facing side of the cap body remains sealed light-tight.
  • the mask is coated with a transparent or translucent paint to level the surface.
  • the film is glued to the transparent or translucent paint.
  • the transparent or translucent paint are the one transparent substrate, a plurality of refractive globules bonded in optical contact with the substrate, an opaque matrix surrounding the beads, and optionally a diffuser or a diffuser layer for light scattering-containing film.
  • the cap bodies are coated on the side facing the operator with a transparent protective varnish.
  • Figure 1 is a schematic side sectional view of the invention
  • Control element cap shows.
  • Fig. 1 shows an operating element cap according to the invention, which is generally designated 1.
  • the cap 1 comprises a transparent or translucent cap body 2 made of polycarbonate or polymethylmethacrylate, for example Lexan ®, which is manufactured in an injection molding process.
  • an opaque lacquer 3 is applied on the inside of the cap body 2 facing the switch (the lower side of the cap body 2).
  • the paint 3 was processed to produce a symbol 5 reproducing mask with the laser.
  • the underside of the lacquer or the mask (3) is coated with a transparent or translucent lacquer 6, which compensates for the unevennesses in the opaque lacquer 3 produced by the laser processing.
  • a film 4 is glued.
  • a film comprising a transparent substrate, a plurality of refractive globules connected in optical contact with the substrate, an opaque matrix surrounding the spheres and optionally includes a diffuser or a diffuser layer for light scattering.
  • a transparent protective lacquer 7 which is manufactured by the 3M Corporation.
  • the cap body 2 is coated on the side facing the operator (top in FIG. 1) with a transparent protective lacquer 7.
  • a light source located below the key body 1 is a light source, not shown. Light from this light source penetrates the foil 4, penetrates the translucent or transparent lacquer 6 and, due to the mask 3 produced by the opaque lacquer, makes the symbol 5 light up.
