Abstract
A projectile device having a suction cup head made of a novel foam. The foam used in the suction cup head has an open cell density within the foam of between five percent and twenty percent. The suction cup head has a face surface of a first diameter. A shallow concavity is formed in the face surface. The concavity has nearly the same diameter as the face surface, however, the depth of the concavity is no more than one-tenth of that diameter. Furthermore, the face surface of the suction cup head is proportionally large, being at least twenty-five percent as wide as the entire projectile device is long. The combination of a large suction cup head, a shallow concavity and a soft, semiporous foam enables the suction cup head to adhere to both smooth surfaces and rough surfaces.
Claims19
A novelty projectile device, comprising:
- a suction cup head having a face surface of a first diameter and a concavity in said face surface, wherein said suction cup head is comprised of a synthetic foam composition having an open cell concentration of between five percent and twenty percent;
- and
- a shaft for stabilizing said novelty projectile in flight so that said face surface of said suction cup head leads while said projectile device is in flight.
A projectile device comprising:
- a foam suction cup head having a face surface of a first diameter and a concavity in said face surface having a maximum depth no greater than one-tenth that of said first diameter, wherein said foam suction cup head has an open cell density of between five percent and twenty percent;
- and
- a shaft extending behind said foam suction cup head, wherein said shaft and said foam suction cup head provide said projectile device with an overall length, and wherein said first diameter is no less than thirty percent of said overall length.
A suction cup head for a projectile, comprising:
- a face surface;
- a back surface;
- a concavity disposed in said face surface;
- wherein said suction cup head is fabricated from foam containing a mixture of polyethylene-vinyl, ethylene-vinyl acetate, butadiene rubber, high-density polyethylene and calcium carbonate.
