20110104977 | LIGHTED FLYING DISC - A soft, flexible, illuminating flying disk toy may be used for recreation by adults and children and as a fetch toy for animals. The disk is designed as an improvement to existing soft, flexible flying disks by incorporating an illuminated outer edge, typically battery powered. This illuminated outer edge, while sewn into a durable, light weight, tear resistant translucent material, will also provide the semi-rigid support needed to create and maintain stable flight. The illuminated outer edge which is sewn into the translucent durable material is then sewn onto a slightly over-sized central circular disk shaped section of the same or similar material which, when thrown, creates an aerodynamic lift providing stable flight. By incorporating the illuminated outer edge into a soft flying disk, visibility and additional safety are provided when using the disk in dimming light conditions and during the dark of night. | 2011-05-05 |
