The present disclosure relates generally to flying toys and, more particularly, to toy gliders having extending wings. Such flying toys may be launched with an elastic mechanism.
Flying toys are well known, including toy gliders launched with an elastic mechanism, such as a rubber band. However, traditional toy gliders with fixed wings may deliver less than optimal performance due to the drag imposed by the wing. Toy gliders tend to have relatively large wings, which tend to create large amounts of lift. While the large amounts of lift produced by the wings of a glider may be desirable during the gliding phase of flight, the induced drag from such a wing may be problematic during the launching phase.
When a toy glider is launched, such as by an elastic mechanism, the glider may experience relatively high acceleration and may be propelled upwards at a relatively high velocity. Initially, the glider may be accelerated by the tension in the elastic launching mechanism until the glider is free of the launching mechanism. Once free of the mechanism, the glider may be traveling at a higher velocity than its optimal gliding speed, such that the glider may climb due to lift from the wing or the ballistic trajectory induced by the launching mechanism. The glider may continue to climb until it reaches its peak altitude, at which point the glider may transition to a gliding mode of flight in which the weight of the glider instills a forward velocity sufficient for the wings to induce lift.
However, the different conditions during the launch and glide phases of flight may make it difficult to improve both the launching and gliding performance of a fixed configuration glider. For example, launching performance may be improved if a toy glider has relatively low drag, thereby allowing a greater height to be reached. A toy glider may have relatively low drag if a relatively small wing is used. In contrast, gliding performance may be improved if a toy glider produces a relatively large amount of lift, such as due to a relatively large wing. However, large wings tend to produce significant amounts of aerodynamic drag, which would be detrimental to launching performance.
Unlike a glider with a fixed wing, a glider having swinging or extending wings may exhibit improved performance in both the launch and glide phases of flight. In particular, when the wings are in a retracted position, the glider may have relatively low drag such that it may exhibit improved launch performance. Further, when the wings are in an extended position, the glider may have increased lift such that it may exhibit improved glide performance.

Nos. 1,116,122, 1,190,343, 1,842,434, 1,920,746, 2,059,131, 2,078,374, 2,587,699, 3,369,319, 3,408,767, 3,654,729, 4,915,664, 5,299,966, 5,846,112, and 5,934,967. Examples of toy gliders including automatically extending wings are disclosed in U.S. Pat. Nos. 1,116,122, 1,190,343, 1,353,147, 1,842,434, 1,920,746, 2,059,131, 2,078,374, 2,306,866, 2,587,699, 2,765,582 3,006,109, 3,369,319, 3,408,767, 3,380,189, 3,654,729, 3,839,818, 3,943,657, 4,915,664, 5,299,966, and 5,934,967. Examples of toy gliders including wings that retract for launch are disclosed in U.S. Pat. Nos. 3,369,319, 4,915,664, and 5,934,967. Examples of toy gliders including automatically extending wings and a mechanism configured to retard or delay wing extension are disclosed in U.S. Pat. Nos. 2,306,866, 3,006,109, 3,380,189, 3,654,729, and 3,943,657. Examples of mechanisms to automatically extend arms are disclosed in U.S. Pat. Nos. 2,781,596, and 5,934,967. The disclosures of these and all other publications referenced herein are incorporated by reference in their entirety for all purposes.
In one example, a flying toy may comprise an elongate body extending along a body axis with the body comprising a forward end and a rearward end. The flying toy may comprise a wing assembly, which may comprise a wing adapted to move relative to the body between an extended position in which at least a portion of the wing extends away from the body and a retracted position in which the wing portion is closer to the body. The flying toy may comprise an actuator movable along the body between a forward position and a rearward position. One of the wing assembly and the actuator may comprise a contact element, and the other of the wing assembly and the actuator may comprise an elongate contact surface extending obliquely relative to the body axis. The contact element may move along the contact surface as the actuator moves between the rearward position and the forward position, thereby moving the wing between the retracted position and the extended position.
In one example, a flying toy may comprise an elongate body extending along a body axis from a forward end to a rearward end. The flying toy may comprise a wing assembly, which may comprise a wing adapted to pivot relative to the body between a retracted position in which at least a portion of the wing is proximate the body and an extended position in which the wing portion extends away from the body. The flying toy may comprise an actuator movable along the body from a forward position toward a rearward position. One of the wing assembly and the actuator may comprise a contact element, and the other of the wing assembly and the actuator may comprise an elongate contact surface extending obliquely relative to the body axis. The contact element may move along the contact surface as the actuator moves from the forward position toward the rearward position. The motion of the contact element along the contact surface as the actuator moves from the forward position toward the rearward position may enable pivoting motion of the wing from the extended position toward the retracted position.
In one example, a flying toy may comprise an elongate body extending along a body axis, with the body comprising a forward end and a rearward end. The flying toy may comprise a wing adapted to move relative to the body between a retracted position in which at least a portion of the wing is proximate the body and an extended position in which the wing portion extends away from the body. The flying toy may comprise an actuator movable along the body between a forward position and a rearward position. The flying toy may comprise a coupling assembly coupling the actuator with the wing. The coupling assembly may be configured to move the wing from the extended position toward the retracted position as the actuator moves from the forward position toward the rearward position. The flying toy may comprise a retarding assembly, where the retarding assembly is configured to retard motion of the actuator along the body.
