Definitions

  • the present invention relates to a visibility aid, and improvements thereto; the said visibility aid adaptable to be worn by people, animals or attached to inanimate objects.
  • the said visibility aid is designed such that the visibility of the object to which it is attached is enhanced by use of the aid. Environments which are in darkness or of poor visibility due perhaps to fog or smoke, would be particularly suitable for use of the visibility aid therein. In this specific case reference is made to the instance where the visibility aid is worn on the person, with the effect described repeated for whichever object it may be attached to.
  • the said visibility devices have the disadvantage that they require illumination from a source external to the visibility device. With no external light source available the effect of the visibility device is nullified.
  • a further disadvantage of the said visibility devices are that they merely mirror the external light source and afford the device wearer no control over the form or intensity of reflection given out. This control over the reflective power of such visibility devices is desirable especially if it is desired that the reflection be minimised, for whatever reason.
  • a visibility aid has been developed with the aim of providing an enhanced visibility and reflection to the wearer and also providing to the wearer control of the said visibility aid.
  • the present invention provides a visibility aid in the form of reflective material, with one or more light source means mounted thereon, wherein the light source means , when illuminated, interact with the reflective characteristic of the material to increase the visibility of the said visibility aid.
  • the said reflective material shall be in the form of reflective sheet material suitable for attachment to or carried by a person or object.
  • the said visibility device shall include an electrical circuit therein and shall be adapted to be worn or placed on an object such that when contact to complete an electrical circuit is made, a power source acts to illuminate the said light source means and thus increase the visibility of the wearer or object.
  • the sheet of material shall have retroreflective properties and will be positioned to cover the said light sources means. wherein the light source means protrude through the backing material of the said retroreflective material, such that a multiplicity of lights are apparent to the onlooker.
  • the light source means shall be mounted such that the retroreflective material is placed behind the said light sources with a protective layer of plastic material over the said light source means.
  • the effect of the mounting of the light source means, upon illumination, both in front of or behind the retroreflective material is to produce a multiplicity of said lights which are apparent to the onlooker, such a multiplicity enhancing the overall light effect produced upon the illumination of the said light source means such that the value of such a device is greatly enhanced and the inherent safety factor increased.
  • the multiplication of the lights is due to the property of the retroreflective material which, by the reflection of light either therethrough or thereon produces the multiplicity of lights which is visible to the onlooker.
  • the light source means shall be integral parts of an electrical circuit connected to a power source such that should one light source means fail the remainder of light sources will continue to operate.
  • the power source may be mounted as an integral part of the visibility aid and said power source may take the form of batteries which in one embodiment may be rechargeable by solar power panels mounted on the said aid.
  • the completion of the electrical circuit of the visibility aid may be provided by magnetic means mounted such that when the two ends of the band are brought into contact the circuit is completed.
  • the magnetic means so described may be in the form of a reed switch mounted at one end of the band and a magnet mounted in the opposing end such that the reed switch contact is closed upon the positioning of the magnet in proximity thereto.
  • the said electrical circuit may be designed to include a flasher unit such that the lights will flash intermittently upon the circuit being completed.
  • the band may be provided with an adjustment mechanism so that it may be worn or attached to persons or articles of differing dimensions.
  • the visibility aid shall be capable of attachment to inanimate objects such that their location is indicated to onlookers.
  • the light sources may be mounted on metallic foil to further enhance the effect of the light sources when lit.
  • the visibility aid shall be waterproof and water resistant and the said electrical circuit shall be prevented from being exposed outwith the said aid.
  • Figure 1 is a plan view of the Visibility Aid
  • Figure 2 is a sectional view of the visibility aid of Figure 1 along line A-A;
  • Figure 3 is an elevation of the automatic switching device.
  • FIG. 1 Describing one embodiment of the invention with reference to the drawings and firstly to Figures 1 and 2 which show the visibility aid 10 which comprises a reflective band 12 within which are mounted light source means 1 .
  • the said light source means are powered by means of a power source 16, the power transmitted to the light source means 14 by means of an electrical circuit (not shown) .
  • Serving to complete the electrical circuit is an automatic switching device 18.
  • the ends of the said visibility aid are fastened together with the aid of strips of VELCRO 17.
  • Covering the said light source means is the outer part 20 formed of retroreflective material which serves to produce an enlargement of the illuminated light 24 produced by each of the light source means 14. This enlargement is produced by the multiplication of the number of illuminated lights visible, said multiplication dependant on the form of retroreflective fabric fitted and also the distance of the light source means 14 therefrom.
  • Figure 2 illustrates the method of mounting the light source means 14 in the visibility aid and the various layers of material so joined to form the visibility aid.
  • the light source means 14 are mounted such that they are connected by electrical wiring 26 to the electric circuit with the light source covered by the outer part 20 of retroreflective material.
  • the inner part 28 of the material is placed on top of a layer of aluminium foil 30 which in turn is covered by a backing band of material 32 so sealed at each side with the outer part 20 of retroreflective material to form a sealed watertight join.
  • the light source means 14 and associated wiring are mounted between the backing band 32 and the layer of aluminium foil 30, with small holes 34 cut in the said aluminium foil to allow the upper part of the light sources 14 to pass therethrough.
  • the upper part of the light sources in turn passes through a hole 36 of larger diameter cut in the inner part 28 , such that the said light source is visible externally.
  • FIG. 3 One form of switch for the visibility aid, the automatic switching device is shown in more detail in Figure 3 wherein there is shown the reflective band 12 and mounted thereon the strips of VELCRO 17. Within one end 38 of the said reflective band there is mounted a reed switch 40 and in the other end 42 a magnet 44. The said reed switch connected to the main electrical circuit of the said visibility aid.
  • the operation of the visibility aid 10 is relatively simple in that the said aid, when to be worn is placed around, for example, the arm and the two ends 38 and 42 are fastened together by means of the VELCRO fastenings 17.
  • the light sources are not illuminated until the two ends 38 and 42 are brought in to close proximity as shown in Figure 3 such that when this occurs the magnet 44 serves to close the contact 46 of the reed switch 40.
  • the closure of the contact 46 serves to complete the electrical circuit and so the power from the power source 16 is supplied by the electrical circuit to the light sources 14 which are illuminated.
  • the inner part referred to as 28 shall be formed of retroreflective material and the outer part 20 shall be formed of a protective plastic coating ,said light source means thus mounted in front of the said retroreflective element of the inner part 28.
  • the automatic switching device shall not be incorporated into the visibility aid and the operation of the light source means shall be by manual means.
  • the visibility aid shall use the sheet material integrally with the said light source means such that the device is adaptable for use in differing conditions and environments and can be attached to articles and persons of varying dimensions.
  • the visibility aid so described has the advantage of incorporating light sources to provide a light source within the said reflective device thereby eliminating the need for external lighting before the visibility aid is of use.
  • the simplicity of the automatic switching mechanism is of great advantage when used in emergency situations wherein the user wishes to quickly and simply switch on the said light sources, this being effected by the same movement used in the fitting of the said visibility aid to the person.
  • the automatic switch is wholly encased within the visibility aid itself decreases the risk of damage to the said switch when the visibility aid is being used especially when in use in hazardous conditions.
  • the fact that the switch automatically disconnects the power from the light ources upon the removal of the visibility aid serves to save power drain from the power source which could occur if for example the switch was manually operated and the wearer forgot to switch the power supply off upon ceasing to wear the visibility aid.
