Description
Technical Field
The present invention relates to devices securable to or carriable by an individual for calling attention to and/or making the existence of the individual known to others who may pose a possible hazard and more particularly to devices securable to or carriable by an individual for calling attention to and/or making the existence of the individual known to others who may pose a possible hazard that employ a plurality of light emitting devices as an attention attracting artifice.
Background Art
There are numerous situations where it is desirable for an individual to attract the attention of and make known there existence to other individuals in a timely manner to avoid possible injuries. Activities such as walking, jogging and cycling often take place in the cool of the evening, along roads and highways in dark or dimly lit conditions. In addition, children running and playing during the evening hours are often injured by motorists who did not see the child in time to avoid the injury. It would be a benefit, therefore, to have a device securable or carriable by an individual that would draw attention to the individual during dark or dimly lit ambient lighting conditions. It would be a further benefit if the device were lightweight and did not interfere substantially with desirable sporting activities while being worn or carried.

Exemplary Mode for Carrying Out the Invention
FIG. 1 shows an exemplary embodiment of the illuminated safety device of the present invention generally designated by the numeral 10. In this embodiment, safety device 10 includes: a light array, generally designated by the numeral 12; a transparent enclosure, generally designated by the numeral 14 and having a cavity 16 therein containing light array 12; spiraled securing member, generally designated by the numeral 18; and a timing and drive circuit (not shown in the figure) in connection with light array 12 and enclosed within a circuit casing, generally referenced by the numeral 20 that is disposed between enclosure 14 and securing member 18.
Light array 12 includes twelve (12) light emitting diodes (LED's), D.sub.1 -D.sub.12, wired in a wiring harness 22. Wiring harness 22 includes thirteen wires W.sub.1 -W.sub.13 (not shown in the figure) that are enclosed in a section of flexible tubing having twelve holes formed along the length thereof to allow for connection of LED's, D.sub.1 -D.sub.12. The anode of each LED, D.sub.1 -D.sub.12 is connected individually to one each of wires W.sub.1 -W.sub.12, and one wire W.sub.13 is commonly connected to all the cathodes of LED's, D.sub.1 -D.sub.12.
Transparent enclosure 14 is test tube shaped and constructed from clear plastic. Light array 12 is disposed within cavity 16 which is of a length about equal to the length of wiring harness 22. An open end 24 of enclosure 14 is secured in connection with one end 26 of circuit casing 20 with glue.
In this embodiment, securing member 18 is integrally formed with a cap portion 28 of circuit casing 20 and includes a spiral connecting end 30, a first stabilizer 32, and a second stabilizer 34. Stabilizer 32 has a chord or tether receiving aperture 36 formed therethrough to provide additional means for securing safety device 10 to a user if desired. Spiral connecting end 30 is flexible and resiliently returns to its original spiral configuration when any deforming force is removed. In this embodiment, spiral connecting end 30 is described by a decreasing length radius sweeping a line through a four-hundred-eighty (480.degree.) degree arc.
FIG. 2 is a second side view of the safety device 10 shown in FIG. 1 showing LED's, D.sub.1 -D.sub.12, and a slide switch aperture 38 running along the side of circuit casing 20 with a positioning tab 40 of a slide switch 42 extending outward therefrom. As shown in FIG. 3, circuit casing 20 has a battery compartment 44 and a circuit compartment 46 formed therein. In this embodiment, battery compartment 44 is sized to receive a watch or calculator type battery 48 and includes a first battery contact 50. A second battery contact 52 is secured within cap portion 28. Cap portion 28 is internally, and companionately threaded with the external peripheral edge 54 of circuit casing 20 to allow for replacement of battery 48 when required. Circuit compartment 46 is sized to contain the timing and drive circuit (shown schematically in FIG. 4 and discussed in more detail hereinafter below) and has a wiring aperture 56 through which wires W.sub.1 W.sub.13 (shown schematically in FIG. 4) pass.
FIG. 4 is a schematic diagram of the timing and drive circuit used in this embodiment, generally designated by the numeral 58. Circuit 58 includes a ring counter 60 having twelve output lines, L.sub.1 -L.sub.12, and a variable output frequency clock signal generator 62 having a variable resistance slide switch 42 wired therein in a manner to allow the position of the slide switch to vary the output frequency of a clock signal output, CLK.sub.1, of signal generator 62. CLK.sub.1 is wired to a CLK.sub.in input line of ring counter 60. The state of two of the twelve output lines, L.sub.1 -L.sub.12, of ring counter 60 change on the transition of CLK.sub.in from a low voltage state to a high voltage state as shown in the timing diagram of FIG. 5. The anode of each LED, D.sub.1 -D.sub.12, is connected to its respective output line, L.sub.1 -L.sub.12, of ring counter 60 via wires, W.sub.1 -W.sub.12. Only the LED, D.sub.1 -D.sub.12, that is connected to the output line, L.sub.1 -L.sub.12, currently at the high state is illuminated.
Use of safety device 10 is simple. Safety device 10 is turned on by sliding positioning tab 40 along slide switch aperture 38 until light array 12 is functioning at the desired lighting frequency and then securing the safety device 10 to the user by coiling flexible, spiral connecting end 30 about any available support structure such as a belt loop, belt, or button hole and button combination. All twelve LED's, D.sub.1 -D.sub.12, can be made to appear to be simultaneously illuminated by increasing the frequency to a frequency at which each LED is lighted at least 30 times a second. Thus both a chaser type display and a fully illuminated display may be selected by a user.
It can be seen from the preceding description that an illuminated safety device has been provided that includes an attachment mechanism easily securable to a variety of locations on an individual; that includes at least two mechanisms for allowing a user to secure the device to the user; and that allows the user to select and vary the attractant illuminated display of the safety device.
