  "abstract": "This invention comprises a time delay release device which can be carried by a kite or similar aerial toy. The device consists of an elongated resilient material having at its ends a holding means such as a tongue and hole or pin and hole arrangement for releasably holding a line. Proximal to each of these ends is the time delay mechanism which consists of an adhesive means for holding the ends together. However, after a period of time when the resilient force of the elongated material exceeds the adhesive force, the ends separate and the article is released. The device can be reused, and when the adhesive force decreases due to wear the adhesive member is replaced. Velcro can be used in place of the adhesive member.",
  "claims": [
    "1. A time delay release device comprising an elongated piece of resilient material the ends of said elongated material having adhesive means to hold an article and subsequently release said article after a defined time duration; said adhesive means which maintains said ends adjacent to each other consists of a series of apertures on each of said ends, and an adhesive strip overlaying said apertures on the same side of said piece of material whereby, when said ends are positioned adjacent to each other and the adhesive strip overlaying said apertures on each end is pressed into common engagement, said ends will be maintained adjacent to each other until the resilient force of said resilient material overcomes the holding adhesive force, and thereby releases said article.",
    "2. A time delay release device as in claim 1 wherein there are at least three apertures on each end overlayed with adhesive strips.",
    "3. A time delay release device as in claim 2 wherein said apertures have varying diameters.",
    "4. A time delay release device as in claim 3 wherein intermediate said ends is means to attach said device to a carrier apparatus.",
    "5. A time delay release device as in claim 4 wherein said carrier apparatus is a kite.",
    "6. A time delay release device as in claim 1 wherein said article holding means includes a pin on one of said ends and an opening to receive said pin on the other of said ends.",
    "7. A time delay release device as in claim 6 wherein said adhesive means which maintains said ends adjacent to each other consists of a series of apertures on each of said ends, and an adhesive strip overlaying said apertures on the same side of said piece of material whereby, when said ends are positioned adjacent to each other and the adhesive strip overlaying said apertures on each end is pressed into common engagement, said ends will be maintained adjacent to each other until the resilient force of said resilient material overcomes the holding adhesive force."
