DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(18) The present invention is directed to a portable light having a flexible member. The portable light may be attached to an object or may be wearable around a user's neck. There is a light source at each end of the portable light to provide the necessary illumination to an area of interest such as in an automotive garage or a work area in the home or for recreational purposes such as camping or reading. The portable light of the present invention includes a flexible member adapted to be attached to an object or to fit around a user's neck and body members at each end of the flexible member having a light source. There may be an additional light source, e.g. a flood light, in one of the body members. The flexible member allows each body member to be adjusted to focus each light source independently of the other. There is a power source in one body member to power the light sources and controlled by at least one on/off switch.

(19) Referring to the Figures, there is shown a portable light 20. The portable light 20 includes a flexible member 22, body members 24 and 26, light sources 28 and 30, and switches 74 and 76. The portable light 20 will now be discussed in further detail.

(20) Referring to FIG. 8, there is shown an exploded view of the portable light 20 and includes components of the portable light 20 as follows: #60 LENS CAP #62 LENS #64 REFLECTOR #66 COB LIGHT #68 HEAT SINK #70 HEAT SINK HOLDER #72 O-RING #74,76 POWER SWITCHES #78 INJECTION MOLDED SHELL A #80 SCREW 1 (12) #82 USB COVER #84 USB CHARGE PORT #86 SCREW 2 (2) #88 INJECTION MOLDED SHELL B #90 FLOOD LIGHT LENS COVER #92 FLOOD LIGHT LENS #94 COB LIGHT #96 SCREW 3 (4) #98 WIRE CAP #100 PCB BOARD A #102 SWITCH STOP #104 FLEXIBLE ELASTOMERIC WIRE COVER #106 INJECTION MOLDED SHELL C #108 LITHIUM ION BATTERY #110 SPRING #112 SNAP FIT CLIP #114 SNAP FIT CLIP RECEPTACLE #116 SPRING LOADED DETENT #118 INJECTION MOLDED SHELL D #120 PCB BOARD B #122 MAGNET #124 NON-SLIP FEET/GRIP

(21) The various components of the portable light 20 will now be discussed in further detail. Flexible member 22 is adapted to attach to an object as shown in FIG. 15 or to fit around a user's neck and may rest on the shirt collar, of the user or fit comfortably around the neck of the user. The light may also be self-standing by adjustment of the flexible member or may be hand carried to focus the light source(s).

(22) Referring, for example, to FIGS. 9-13, the flexible member 22 comprises a flexible wire 40 having L-shaped ends 42,44 which attach to the housing of each body member 24 and 26. Surrounding structural wire 40 is a flexible sleeve 46 preferably constructed of a metal coil. Surrounding the flexible sleeve 46 and flexible wire 40 is a soft elastomeric material 104, e.g. silicone, having a tubular member 50 and extending from tubular member are a plurality of soft flexible ribs 52. Structural support spines 54 and 56 are provided to give support to ribs 52 and are preferably spaced 180 degrees from each other. Ribs 52 extend outward from tubular member 50.

(23) Each body member 24 and 26 includes a COB (chips on board) LED light source. Each light source preferably provides 200 lumens of light. Body members 24 and 26 are a molded ABS plastic. Body member 24 includes housing members 106 and 118 and body member 26 includes housing members 78 and 88, these structures being held together by screws 80. Each body member 24 and 26 include the lighting components, including an LED COB light source 66, lens cap 60, lens 62, reflector 64, heat sink 68, heat sink holder 70 and O-ring 72.

(24) Body member 26 further includes an LED COB light source 94 on the side of the body member to function as a flood light. The light source preferably provides 300 lumens of light. There is a lens cover 90 and lens 92.

(25) Body members 24 and 26 further includes a wire cap 98 to anchor flexible wire 40 in each body member housing by screws 96. This will prevent rotation of the flexible wire.

(26) Body member 24 includes a power source such as a rechargeable lithium ion battery 108 which powers the three light sources. There is a power wire bushing 130 at each end of the flexible member through which power wires 132, 134 and 136 run through connecting the power source 108 to each of the light sources. Body member 24 includes a PCB board 120 for controlling the light source in body member 24, and body member 26 includes a PCB board 100 for controlling the light sources in body member 26 and USB rechargeable port and recharging indicator. Body member 26 includes a USB rechargeable port 84 to charge battery 108 and which is covered by a USB port cover 82, preferably of a flexible elastomeric material. There may be a recharging indicator light 85 to indicate the charge level of the battery.

(27) Body member 24 includes a magnet 120 for attaching light 20 to a metal object for a hands free light source. There are non-slip feet grips 124 to grip to the object and prevent scratching of the object.

(28) When the light is not in use, body members 24 and 26 may be connected to each other as shown in FIGS. 14A and 14B for ease of storage and to reduce the storage space size. Body member 24 includes a snap fit clip 112 which mates with a snap fit clip receptacle 114 in body member 26. The snap fit clip includes spring loaded detents 116 which may be depressed and released by spring 110. Spring loaded detents fit in detent opening 116A of snap fit clip receptacle 114. Instead of a snap fit clip connection, other connection means may be used such as a magnet and metal plug.

(29) In one presently preferred embodiment, the portable light has the following approximate dimensions:

(30) Light Length=22 to 28 inches and preferably 24.5 inches;

(31) Flexible Member Length=12 to 20 inches and preferably 16 inches;

(32) Flexible Member Height=0.75 to 1 inches and preferably 0.85 inches;

(33) Flexible Member Width=0.75 to 1 inches and preferably 0.8 inches;

(34) Body Member Length=3.5 to 5 inches and preferably 4.5 inches;

(35) Body Member Width=1 to 1.5 inches and preferably 1.25 inches;

(36) Body Member Height=1 to 1.5 inches and preferably 1.25 inches.

(37) The over-molded elastomeric material is preferably made of silicone and is molded over the metal coil. The plurality of ribs 52 are spaced apart approximately 0.125 inches and extend outwardly from the tubular member 50 about 0.125 inches. There are preferably 100 ribs. The durometer range for the silicone elastomeric material is 30 A to 90 A, preferably 40 A to 80 A, and most preferably 48 A to 55 A.

(38) In use, light 20 may be wrapped around an object or placed around a user's neck or held by a user or used as a stand alone light, all by adjusting the flexible member 22. The light sources in the body members may be focused on an environment of use by adjusting the body members using the flexible member 22. In operation, switch 74 may be pushed once to turn on the light source in body member 26, pushed a second time to turn on light sources 28 and 30 in both body members 24 and 26, and pushed a third time to turn off the lights. Switch 76 may be pushed to turn on and off light 94 in body member 26. It is understood that one switch may be used to control all of the light sources.

(39) The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. As will be apparent to one skilled in the art, various modifications can be made within the scope of the aforesaid description. Such modifications being within the ability of one skilled in the art form a part of the present invention and are embraced by the appended claims.
