    Description: The invention relates to a foldable spherical structure made of colored plastic. It is intended as a toy, especially for children.
    Foldable spherical structures made of colored plastic are known. They can be pulled apart and contracted synchronously. Such structures are described, for example, in EP 0 455 850 B1.
    The object was therefore to further develop the foldable spherical structure made of plastic material described in EP 0 455 850 B1 in order to make it more attractive. The spherical structure is said to emit a special light effect that is particularly effective in a dark room or in the dark.
    The object was achieved with light-emitting diodes, the light color emanating from the light-emitting diodes being matched to the dye or the color pigment in the plastic.
    The invention accordingly is a foldable spherical structure made of colored plastic material, which is characterized in that it has at least one LED or OLED (organic light emitting diode), the light of which has at least one dye and / or at least one color pigment in the Plastic material makes it glow.
    The light emitting diodes or OLEDs are preferably located on the inside of the spherical structure. Their size and arrangement is chosen so that they do not hinder the folding of the spherical structure.
    The light emitting diodes or OLEDs are provided with their own energy supply, for example with a battery, a rechargeable battery, a solar cell or a device which converts kinetic energy into electrical energy.
    In the simplest embodiment, the at least one light emitting diode is switched on by a manually operated switch.
    Preferably, however, the switch is combined with an acceleration sensor that turns the LED on and off when the spherical structure is subjected to a predetermined acceleration, i.e. for example when it is thrown into the air.
    In addition or also in addition, a magnetically actuated sensor can be used. The (permanent) magnet and sensor are then arranged at different points in the spherical structure. If the structure is folded up, the magnet and sensor are close together, when they are pulled apart they move away from each other and the magnetic field acting on the sensor is reduced. If the field strength of the magnet drops below a predetermined value, the sensor gives the switch-on signal for the LED or OLED.
    Suitable light emitting diodes and OLEDs are commercially available. They can shine in different colors, for example blue, white or yellow. However, LEDs and OLEDs which emit blue light with a wavelength of 450 to 470 nm are preferred. These are best suited to make the dye or pigment in the plastic parts of the spherical structure glow. It should be taken into account that the radiation emitted by the dyes or color pigments is normally longer-wave than that of the radiation with which they are excited.
    Instead of individual LEDs or OLEDs, LED chains can also be used. These are also commercially available.
    Dyes and color pigments are chosen according to the wavelength of the light emitted by the LEDs or OLEDs. Generally, they are organic and / or inorganic pigments or dyes, especially so-called neon colors or fluorescent colors (e.g. Pantone 801 - 814).
    The inorganic color pigments are, for example, copper-activated 1/10
    AT 15 608 U1 2018-03-15 Austrian
    Patent Office for zinc sulfide (ZnS: Cu). Such pigments are commercially available, for example under the name 7Lumilux Effect Blue SN from Honeywell or 7LumiNova from Nemoto & Co., Ltd. The LumiNova pigments are based on strontium aluminate (SrAI 2 O 4 or Sr 2 AI 2 O 5 ). They are excited by light with a wavelength of less than 365 nm. The intensity of the luminescence depends, among other things, on the size of the pigment particles. In general, the smaller the particle size, the stronger the afterglow effect. The radiation emitted by the dyes or color pigments generally has a longer wavelength than the one used to excite them, ie the wavelength of the emitted radiation is shifted in the direction of ArotO.
    Suitable organic dyes or color pigments are substituted pyrenes or substituted coumarins, such as 6,8-difluoro-7-hydroxy-4-methyl-3- (succinimidooxycarbonylmethyl) coumarin (7Marina Blue).
    The dyes or pigments are u. a. selected according to the polarity of the plastic material used. For a plastic with polar properties, e.g. Polyamide, a correspondingly polar dye or pigment will come into question. In addition to dyes or color pigments with luminescent properties, those without luminescent properties can of course also be used.
    [0017] The foldable spherical structure comprises strut elements and hub elements. Two strut elements are rotatably connected at one end to another pair of strut elements with the help of pins and corresponding holes. In addition, each strut element is rotatably connected to another strut element, so that a scissor-like structure is created. The ends of 3 or 4 pairs of scissors elements converge on the hub elements. Two hub elements lie on top of each other. The strut elements are rotatably mounted on the hub elements. Depending on the size of the spherical structure, there are approximately 20 to 40 pairs of hub elements. A symmetrical arrangement with 26 pairs of hubs is preferred, which has 3 four-fold axes of rotation which are at right angles to one another. 4 pairs of strut elements run together on 18 pairs of hubs, 3 pairs of strut elements each on 8 pairs of hubs.
    The individual strut elements preferably have a length of 3 to 8 cm, preferably 4 to 6 cm. The strut and hub elements can each be colored with the same or different types of dyes and / or color pigments and thus also produce a correspondingly different color impression. The radiation emitted by the LEDs or OLEDs excites at least one of the dyes or color pigments, the color impression generally changing. The strut and hub elements can be manufactured by methods known to those skilled in the art, for example in an injection molding process.
    The plastic used for the foldable spherical structure according to the invention is preferably transparent or semi-transparent in order to bring out the luminescent properties of the color pigment and / or the dye in the best possible way. Generally suitable are thermoplastically moldable plastics such as polyethylene (HDPE, LDPE or LLDPE), polypropylene, polybutylene, polyacrylate, acrylonitrile / butadiene / styrene copolymers (ABS), polystyrene, polyvinyl chloride, polyvinylidene chloride, etc.
    The spherical structure according to the invention preferably has a diameter of 15 to 60 cm, particularly preferably 25 to 40 cm, in the fully expanded state. When folded, the diameter is only about half as large or even smaller.
    Description of the Figures:
    1 shows a cross section of a foldable spherical structure according to the invention in expanded form with hub elements 40 and strut elements 50 and 60.
    FIG. 2 shows a cross section of a foldable spherical structure according to the invention in a folded form, the reference symbols having the same meaning as in FIG. 1.

    Structure can be movably connected to each other. The hub elements 40 have a base body 41 with brackets 42 and receptacles 43, in which the ends of the strut elements 50 and 60 are rotatably supported by means of pins 53 and 63. The strut elements 60 have pins 64 which engage in bearings, especially in bores, 54 of the strut elements 50, so that they are rotatably connected to one another in a scissor-like manner. The strut elements each have a first arm 51 and 61 and a second arm 52 and 62, which are arranged at an angle of about 10 to 25 ° to each other. The receptacles 42/43 expediently do not completely surround the pins 53/63 in order to facilitate assembly.
    Fig. 4 shows a perspective view of a possible arrangement of the hub elements. In addition to hub elements 40, on each of which 4 strut elements are rotatably mounted, there are hub elements 30, on each of which 3 strut elements are rotatably mounted. The hubs are arranged in pairs. For the sake of clarity, the connecting struts are not shown. Furthermore, a ball 10 with longitudes and latitudes is shown to clarify the spatial arrangement.
    Fig. 5 shows a hub member 30 with a base 31 and bearings 32 and 33 for receiving pins which are arranged at the end of a strut element.
    Figure 6 shows part of a foldable spherical structure according to the invention. Only the components are shown, on which 4 strut elements converge.
    At least individual hub elements expediently have a recess or a cavity for receiving the LED or OLED and the associated power supply and switching sensors (not shown in the figures). It is preferably hub elements in the interior of the spherical structure which have such cutouts or openings. Of course, the LED or OLED and the hub can also be connected by an adhesive connection.
    The LEDs or OLEDs are preferably arranged so that they radiate radially inwards and / or tangentially to the inside of the spherical structure. Since LEDs usually only produce a relatively narrow cone of light (approximately 15 °), it may be expedient to provide an optical lens that widens the cone of light. The aim is to illuminate as many structures as possible with the dye or pigment as intensely as possible and not simply to emit the light to the outside.
