ABSTRACT:
TECHNICAL FIELD
The present invention relates to displays items that are adapted to be secured to the antenna of a vehicle and more particularly to a vehicle antenna display system for use on a vehicle antenna attached to a vehicle and extending upwardly from the vehicle terminating at a top antenna end; the vehicle antenna display system including an antenna slide member having an antenna slide tube having a tube diameter sufficient to be slidably positionable over the top antenna end of the vehicle antenna and a stop member having an antenna end attachment structure securable to the top antenna end of the vehicle antenna and sized larger than the tube diameter of the antenna slide tube; the antenna slide member including a wing portion intersected by the antenna slide tube at an angle “A” of greater than ten degrees and a tail member attached to the antenna slide tube along a side section of the antenna slide tube having a lowest portion of the wing portion in connection therewith; the tail member having sufficient wind resistance such that, when the antenna slide member is slidably installed over the end of a vehicle antenna, blowing air exerts a tail member force against the tail member sufficient to bias a leading edge portion of the wing member into the blowing air such that blowing air generates a lifting force against the wing portion sufficient to slide the antenna slide member upward along the vehicle antenna.
BACKGROUND ART
Individuals often enjoy providing displays on their vehicles such as bumper stickers, window flags, window decals and antenna displays. It would be a benefit, therefore, to have a vehicle antenna display system. Because the eye is drawn to movement, such as a waving flag, it would be further desirable if the vehicle antenna display system moved as the vehicle traveled along. As a further novelty it would also be desirable if the antenna display system included a sliding member that would slide up and down the vehicle antenna depending on the speed of the vehicle.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide a vehicle antenna display system for use on a vehicle antenna attached to a vehicle and extending upwardly from the vehicle terminating at a top antenna end; the vehicle antenna display system including an antenna slide member having an antenna slide tube having a tube diameter sufficient to be slidably positionable over the top antenna end of the vehicle antenna and a stop member having an antenna end attachment structure securable to the top antenna end of the vehicle antenna and sized larger than the tube diameter of the antenna slide tube; the antenna slide member including a wing portion intersected by the antenna slide tube at an angle “A” of greater than ten degrees and a tail member attached to the antenna slide tube along a side section of the antenna slide tube having a lowest portion of the wing portion in connection therewith; the tail member having sufficient wind resistance such that, when the antenna slide member is slidably installed over the end of a vehicle antenna, blowing air exerts a tail member force against the tail member sufficient to bias a leading edge portion of the wing member into the blowing air such that blowing air generates a lifting force against the wing portion sufficient to slide the antenna slide member upward along the vehicle antenna.
Accordingly, a vehicle antenna display system for use on a vehicle antenna attached to a vehicle and extending upwardly from the vehicle terminating at a top antenna end. The vehicle antenna display system including an antenna slide member having an antenna slide tube having a tube diameter sufficient to be slidably positionable over the top antenna end of the vehicle antenna and a stop member having an antenna end attachment structure securable to the top antenna end of the vehicle antenna and sized larger than the tube diameter of the antenna slide tube; the antenna slide member including a wing portion intersected by the antenna slide tube at an angle “A” of greater than ten degrees and a tail member attached to the antenna slide tube along a side section of the antenna slide tube having a lowest portion of the wing portion in connection therewith; the tail member having sufficient wind resistance such that, when the antenna slide member is slidably installed over the end of a vehicle antenna, blowing air exerts a tail member force against the tail member sufficient to bias a leading edge portion of the wing member into the blowing air such that blowing air generates a lifting force against the wing portion sufficient to slide the antenna slide member upward along the vehicle antenna.
