Description:
FIELD OF THE INVENTION  
       [0001]     This invention relates to wrist bands, and, more particularly, to a wrist band having an array of light sources such as LEDs which are activated by movement of an inertia switch to the closed position after depressing a manually-activated switch.  
       BACKGROUND OF THE INVENTION  
       [0002]     For a number of years, articles of footwear and various items of clothing have been sold with decorative arrays of light sources such as light emitting diodes (LEDs). This has been particularly popular in children&#39;s shoes where the LEDs are arranged to complement other design elements of the shoe such as cartoon characters and the like.  
         [0003]     In a typical design of this type, a module carried by the article of clothing is provided having a battery, a switch and, conventionally, an integrated circuit which is connected by wires to LEDs positioned at selected locations in or on the article of clothing. Systems of this type are shown, for example, in U.S. Pat. Nos. 6,525,487; 6,286,975; 6,012,822; 5,969,479; 5,894,201; 5,812,063 and others.  
         [0004]     The integrated circuits employed in modules for these applications are commonly activated by one or more switches carried on or otherwise coupled to the module. In some designs, the switch turns on and off in response to the application of an inertial force, pressure or motion. Spring switches such as disclosed in U.S. Pat. Nos. RE37,220 and 5,909,088 are a popular choice because they are reliable, noiseless and movable from a neutral or off position to a closed or on position in response to motion of the article to which the module is attached.  
         [0005]     Another type of switch employed in children&#39;s shoes and similar applications is a manually activated switch such as shown in U.S. Pat. Nos. 5,894,686; 6,278,378 and 5,813,148. Manual switches are used to turn on and off the light source carried by the article of clothing, to select different modes of operation for the integrated circuit associated with the clothing item, e.g. different flashing sequences or other operations, and for other purposes. One system, particularly intended for shoes and shown in the U.S. Pat. No. 5,813,148 patent, employs both manual and inertial switches to activate light sources and/or sound sources associated with the shoe. In the &#39;148 system, the manual switch turns on and off a light source, and also causes a controller including an integrated circuit to activate a particular mode of operation. One of the modes of operation enables an inertia or pressure sensitive switch, which then operates to activate the light source in a selected flashing sequence.  
       SUMMARY OF THE INVENTION  
       [0006]     This invention is directed to a wrist band having a decorative array of light sources such as LEDs illuminated by an integrated circuit (“IC”) which is activated by movement of an inertia switch to a closed position when a separate, manually-operated switch is closed.  
         [0007]     The wrist band has a body which mounts cooperating fastening elements at either end such as snaps, hook and loop fasteners and the like which allow the body to be secured on the wrist of a wearer. A decorative array of LEDs is mounted to the body, which is preferably also provided with designs such as a cartoon character. The IC, coupled to the LEDs, is activated in response to movement of the inertia switch to a closed position. The inertia switch, in turn, is enabled by depressing a manually-activated switch.  
         [0008]     In response to closing of the manually-activated switch, the inertia switch is coupled to a battery carried by the body. When the wearer of the wrist band moves his or her arm, the inertia switch closes thus coupling the battery to the IC. In turn, the IC illuminates the LEDs in a flashing sequence which is repeated every time the inertia switch is close while the manually-activated switch remains in the closed position. In order to disconnect the battery from the IC, the manually-activated switch is opened.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0014]     Referring now to the Figs., the wrist band  10  of this invention comprises a body  12  formed of two half sections  14  and  16  which are connected together at their peripheral edges by glue, stitching or some other permanent means of attachment. At least one of the half sections  14 ,  16  is decorated with a cartoon character, “super hero” or some other indicia popular with children (not shown). An array of light sources such as LEDs  18  is mounted to one or both of the half sections  14 ,  16  of the body  12 .  
         [0015]     One end of the body  12  mounts one or more fastening elements  20  and the opposite end mounts a fastening element  22  which readily engage and disengage with one another. A snap arrangement is shown in the Figs., but the fastening elements  20  and  22  may be cooperating hook and loop fasteners, a belt buckle type of fastener or any other suitable means of securing the body  12  to the wrist of a wearer.  
         [0016]     In the presently preferred embodiment, a module  24  is mounted in a space  26  between the half sections  14  and  16  of the body  12 . The module  24  carries a battery  28 , a manually-activated switch  30 , an inertia switch  32  and an IC  34 . These elements may be coupled together in series as depicted in  FIG. 4 . The IC  34 , in turn, is coupled to the LEDs  18  by wires as schematically depicted in  FIG. 4 . While the elements  28 ,  30 ,  32  and  34  are illustrated as being carried on a module  24 , it should be understood that they could be mounted in any suitable fashion within the space  26  between the half sections  14 ,  16  of the body  12 .  
         [0017]     One type of inertia switch  32  suitable for use in the module  24  is disclosed in U.S. Pat. No. 5,408,764. The IC  34  is available under part number 6608 from Cheerine Development (Hong Kong) Ltd., having a place of business at Room 1217, North Tower, Concordia Plaza, No. 1 Science Museum Road, Tsim Sha Tsui East, Kowloon, Hong Kong.  
         [0018]     Preferably, but not necessarily, the manually-activated switch  30  is positioned immediately adjacent the half section  16  of body  12  where an indicia (not shown) is present indicating the location of the manually-activated switch  30  and including the designation “on/off.” Further, it is desirable, but not required, that such on/off indicia be located on the half section  14  or  16  of the body  12  which engages the wrist of the wearer and is thus hidden from view.  
         [0019]     The wrist band  10  of this invention operates as follows. Assuming for purposes of discussion that the “on/off” indicia is located on the half section  14  or  16  to be placed on the wrist of the wearer, the manually-activated switch  30  is depressed to place it in the “on” or closed position. The wrist band  10  is then placed around the wrist of the wearer and secured in place by attaching the fastening elements  20  and  22  together. In response to movement of the body  12  of the wrist band  10 , the inertia switch  32  is movable to a closed position thus coupling the IC  34  to the battery  28  since the manually-activated switch  30  is also in the closed position. For purposes of this discussion, the inertia switch  32  and IC  34  may be collectively referred to as a “controller.” The IC  34  is operative to illuminate the LEDs  18  in a flashing or other type of lighting sequence. Once the lighting sequence has terminated, the IC  34  resets and can again be activated by movement of the inertia switch  32  to the closed position, so long as the manually-activated switch  30  remains closed. The battery  28  is disconnected from the inertia switch  32  and IC  34  by depressing the manually-activated switch  30  to move it from the closed to open position.  
         [0020]     While the invention has been described with reference to a preferred embodiment, it should be understood by those skilled in the art that various changes may be made and equivalents substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
