Abstract
A display device in which a banner towed behind a moving vehicle such as a boat, is stabilized by a self-regulating drogue parachute attached to the trailing end of the banner so as to maintain the banner in a vertical plane with its longitudinal axis substantially horizontal, for a wide range of air speeds. When not in use, the banner is wound onto a roller rotatably and removably mounted on a support carried by the vehicle.
Claims26
A display device for towing behind a vehicle, comprising:
- a banner having a leading edge, a trailing edge and two longitudinal edges;
- leading edge attachment means for attachment of said leading edge of the banner to said vehicle, including a roller on which the banner may be wound when not in use and support means adapted to be mounted on the vehicle to support the roller above the surface over which the vehicle moves, for rotation about its longitudinal axis with said axis substantially vertical;
- a stay attached to said trailing edge of said banner at positions adjacent said longitudinal edges thereof to maintain said trailing edge extended, in use;
- aerodynamically stable drogue means comprising an open-ended, flexible sleeve having a leading end and a trailing end, and
- means connecting said leading end of said drogue means to said stay such that the upper portion, in use of said device, of said leading end is closer to said stay than the lower portion of said leading end,
- said drogue means providing sufficient lift and drag to maintain said towed banner in a substantially vertical plane with its longitudinal axis substantially horizontal.
A display device for towing behind a boat, comprising:
- a banner having a leading edge, a trailing edge and two longitudinal edges;
- leading edge attachment means for attachment of said leading edge of the banner to said vehicle, including a roller on which the banner may be wound when not in use and support means adapted to be mounted on the vehicle to support the roller above the surface on which the vehicle moves, for rotation about its longitudinal axis with said axis substantially vertical;
- a stay attached to said trailing edge of said banner at positions adjacent said longitudinal edges thereof to maintain said trailing edge extended, in use;
- a weight provided at the lower end of said stay to help maintain said stay vertical, in use, said weight having a lower planing surface which will plane along the water surface;
- and
- aerodynamically stable drogue means connected to said stay,
- whereby, in use of said device with said banner being towed behind said boat, said drogue means provide sufficient lift and drag to maintain said banner in a substantially vertical plane with its longitudinal axis substantially horizontal.
A display device for towing behind a vehicle, comprising a banner having a leading edge, a trailing edge and two longitudinal edges, leading edge attachment means for attachment of said leading edge of the banner to said vehicle, and aerodynamically stable drogue means connected to said trailing edge of the banner at positions adjacent said longitudinal edges thereof, wherein said leading edge attachment means include a roller on which the banner may be wound when not in use and to which said banner is releasably attached and support means adapted to be mounted on the vehicle to support the roller above the surface on which the vehicle moves for rotation about its longitudinal axis with said axis substantially vertical, and wherein the drogue means provide sufficient lift and drag, when the banner is towed behind said vehicle in use of said device, to maintain the banner in a substantially vertical plane with its longitudinal axis substantially horizontal.
A display device for towing behind a vehicle, comprising:
- a banner having a leading edge, a trailing edge and two longitudinal edges;
- a roller to which said leading edge of said banner is attached and on which the banner may be wound when not in use;
- mounts adapted to engage the ends of said roller and in which the roller is releasably mounted for rotation about its longitudinal axis;
- a post carried by said vehicle for display of said banner from which said mounts are supported to support the roller above the surface on which the vehicle travels with its longitudinal axis substantially vertical, said post being pivotally mounted on the vehicle for pivotal adjustment about an axis substantially perpendicular to the planes of display of the banner, and
- aerodynamically stable drogue means connected to said trailing edge of said banner at positions adjacent said longitudinal edges thereof,
- whereby, in use of said device with said banner being towed behind said vehicle, said drogue means provide sufficient lift and drag to maintain said banner in a substantially vertical plane with its longitudinal axis substantially horizontal.
A display device for towing behind a relatively low speed vehicle comprising:
- (a) an elongated display banner towed in a substantially vertical plane behind a vehicle;
- (b) banner stowage means attached to the vehicle and connected to a leading end of the banner, said stowage means including structure for releasing said banner for towing and retrieving the towed banner for storage;
- and,
- (c) towed banner stabilizing means comprising lift creating means for providing lifting forces when towed at relatively low speed and connecting means for connecting the lift creating means to the trailing end of said banner, said connecting means effective to transmit lifting forces from said lift creating means to said banner trailing end while maintaining said banner substantially in said plane.
