Abstract: A convertible aircraft system is provided that can convert to a helicopter configuration, an airplane configuration, or a gyroplane configuration before, during, or after flight. The convertible aircraft system includes a fuselage, a proximal flight assembly, a distal flight assembly, a support spar, and a tail assembly. The fuselage is the main structural body of the present invention. The proximal flight assembly and the distal flight assembly are the flight system of the present invention. The support spar provides an axis of rotation and a pole support for the proximal flight assembly and the distal flight assembly. The tail assembly provides stability during flight of the present invention. In more detail, the tail assembly may comprise at least one vertical stabilizer, at least one horizontal stabilizer, and at least one rudder in order to provide stability during flight of the present invention.

Abstract: An instant no-sew and removable fabric fastener is similar to a spring push-pin fabric fastener, and thus, the instant no-sew and removable fabric fastener includes a fastener socket and a fastener stud. However, the instant no-sew and removable fabric fastener is different than a standard spring push-pin fabric fastener by incorporating a rotational-type attachment mechanism and by being completely removable. The rotational-type attachment mechanism allows the fastener stud and the fastener socket to be deadlocked to each other. The fastener stud cannot be detached from the fastener socket even with a force until either the fastener socket or the fastener stud is rotated 90 degrees. After the fastener socket or the fastener is rotated 90 degrees, the fastener stud can be detached from the fastener socket. Additionally, this means the instant no-sew and removable fabric fastener does not permanently attach to fabric and thus, can be removed when desired.

Abstract: A magnetically actuated visual display board comprises a grid array of open ended chambers. Display configurations in each chamber utilize a magnetically responsive sliding element to move a display loop to alternate between two different display surfaces to create a desired visual array. A magnetic rod passing a chamber moves the sliding element within the chamber.

Abstract: A center foam strip has a series of transverse fold lines separating the strip into panels which fold onto each other in an accordion pattern for storage. A soft fabric waterproof cover material is attached to the center foam strip to hang down the sides of the vehicle to be closed in the vehicle doors shading the side windows. The cover material and center foam strip are sewn together to conform to the shape of the top of a particular vehicle with the foam strip covering the roof, windshield, and rear window. The center foam strip and surrounding soft fabric are held in place by the trunk lid, doors, and windshield wipers.

Abstract: A self roll-up car cover has a built-in spring between waterproof sheets or a synthetic sheet with a built-in memory to return to a spiral shape when rolled out of the spiral configuration and then released. The rear half of the cover has an end rod and a central opening that allows it to be hooked over a trunk lock mechanism and kept secure when the trunk is then shut. The front half of the cover has a lead rope or belt with two hooks for securing under the hood of the vehicle or any other edged surface. The tension in the cover keeps it stretched out and the overlapping portion of the front and back covers maintains at least a portion of the cover elevated above the vehicle.

Abstract: A spring tensioned roller and spaced tension bar have a vehicle cover folded in half and rolled around the spring tensioned roller. The rear half of the cover has an end rod and a central opening which allows it to be hooked over a trunk lock mechanism and kept secure when the trunk is shut. The front half of the cover has a lead rope or belt with two hooks for securing it under the hood of the vehicle or any other edged surface on the front of the car. The tensioned cover is elevated above the roof of the vehicle by the roller and tension bar for purposes of ventilation.
