This disclosure relates to propeller assemblies and control systems for flying toys.
Flying toy entities may utilize various types of components to create propeller assemblies and toy entity structures to assist in generating lift for the toy entity. Various types of control systems may also be used to direct operation of the components. Improvements in electronics and mechanics continue to reduce the weight of the components and also provide additional packaging space to create new flying toy entities which improve play patterns and enjoyment for a user. Traditional flying toys have used multiple forms of manual or spring launched gliders providing horizontal flight as well as manual or spring launched propeller toys for vertical flight. Toy helicopters in particular have benefited from the improvements in electronics and mechanics. A desire remains for non-helicopter style lightweight electric motorized vertical interactive flying toys.
A flying toy doll includes a doll body extending in a longitudinal direction and having a longitudinal axis being substantially vertical. The doll has a mid-body section defined longitudinally between an upper body section and a lower body section, a head secured to the upper body section, and a pair of arms secured to the upper body section and each extending outwardly therefrom. The doll also has an upper propeller assembly and a lower propeller assembly. The upper propeller assembly is mounted to the doll body and has at least two upper blades hinged at a proximal end of the upper blade for pivotal movement such that a distal blade end moves between at least a resting position and a flying position. In the flying position, the upper blades are generally perpendicular to the longitudinal axis of the doll body and each of the upper blades has a leading edge and a trailing edge extending between the distal end and proximal end of the upper blades, and a safety arc portion. A lower propeller assembly is mounted to the doll body and offset at a longitudinal distance below the upper propeller assembly and has two or more lower blades hinged at a proximal end of each of the lower blades for pivotal movement such that a distal blade end of each of the blades moves between at least a resting position and a flying position. In the flying position, the lower blades are generally perpendicular to the longitudinal axis of the doll body. Each of the lower blades has a leading edge and a trailing edge extending between the distal end and proximal end of the lower blades, and a safety arc portion. The upper leading edges of the upper blades are oriented opposite the lower leading edges of the lower blades. The two upper blades and the two or more lower blades form an appearance of a skirt and conceal at least a portion of the lower body portion of the doll when in the resting positions.
A flying toy figure includes a doll body extending in a longitudinal direction and has a longitudinal axis which is substantially vertical. A first propeller assembly is mounted to rotate in a first direction about the longitudinal axis of the doll body and positioned longitudinally along a mid-portion of the doll body. A second propeller assembly is mounted to rotate in a second direction about the longitudinal axis of the doll body and is positioned below the first propeller assembly. The second propeller assembly is mechanically linked to the first propeller assembly for counter rotation in the second direction when the first assembly rotates in the first direction. A motor is in communication with the first and second propeller assemblies to drive the first and second propeller assemblies in the first and second direction at a speed. A rechargeable power source is in communication with the motor. A switch is secured to at a foot portion of the body to detect a surface external to the doll body and is configured to provide a surface detection signal. A controller is in communication with the motor and switch and configured to adjust a speed of the motor in response to receiving the surface detection signal from the switch. Adjusting the motor speed adjusts a counter-rotational speed of the first and second propeller assemblies.
A flying toy doll includes an upper section, a pair of arms fixed to the upper section, a head fixed to the upper section, a central shaft extending from the upper section and defining a central axis extending in an upright direction, a lower section fixed to the central shaft, a mid-section disposed between the lower section and the upper section and mounted to the central shaft for rotation about the central axis, and a leg member fixed to the lower section. The flying toy figure also includes a first propeller mount mounted to the central shaft for rotation in a first direction about the central axis and pivotal movement about a first propeller mount axis defined by two upper receiving brackets extending outward. The flying toy figure also includes a first set of blades. Each blade of the first set of blades is connected to the first propeller mount to pivot at a first proximal end mounted to one of the upper receiving brackets for hinged movement at the first proximal end between at least a lowered and raised position, and includes a safety arc extending from the proximal end to the distal end. A second propeller mount is mounted to the central shaft below the mid-section for rotation in a second direction and defines at least two lower receiving brackets extending outward. A second set of blades, each defining a second proximal end, are mounted to one of the lower receiving brackets for hinged movement at the second proximal end between at least a lowered and raised position. A gear train mechanically links the first and second propeller mounts for counter rotation such that the second propeller mount rotates in the second direction when the first propeller mount rotates in the first direction. The flying toy doll also includes a motor in communication with the gear train, a rechargeable power source in communication with the motor, a lower transmitter secured to the leg member to transmit a lower detection signal, a lower receiver secured to the lower section to receive a reflected lower detection signal indicative of a surface being external to the toy doll at a distance, and a controller in communication with the motor, the lower transmitter, and the lower receiver. The controller is configured to adjust a speed of the motor in response to the lower receiver receiving the reflected lower detection signal. Adjusting the motor speed adjusts a counter-rotational speed of the first and second propeller mounts.
A flying toy figure includes an upper section, a pair of arms extending upward from the upper section, a head fixed to the upper section, a central shaft extending from the upper section and defining a central axis extending in an upright direction, a lower section fixed to the central shaft, a mid-section disposed between the lower section and the upper section and mounted to the central shaft for rotation, and a leg member fixed to the lower section. A first propeller mount is mounted to the central shaft for rotation in a first direction and pivotal movement, and defines two upper receiving brackets. Each blade of a first set of blades is connected to the upper receiving brackets to pivot between at least two positions. A second propeller mount is mounted to the body mid-section for rotation in a second direction and defines four lower receiving brackets extending outward. Each blade of a second set of blades is connected to one of the lower receiving brackets to pivot between at least two positions. The flying toy figure also includes a flybar mount mounted to the central shaft for rotation in the first direction and pivotal movement, a flybar mounted to the flybar mount, a gear train mechanically linking the first and second propeller mounts for counter rotation, a motor secured to the lower section and in communication with the gear train, and a rechargeable power source in communication with the motor. A controller is configured to direct operation of the motor and rechargeable power source. An upper transmitter is secured to the head, oriented to send an upper detection signal in an upward direction relative to the head, and in communication with the controller. An upper receiver is secured to the head, oriented to receive the upper detection signal when reflected off of a surface, and in communication with the controller. The controller is configured to adjust a speed of the motor in response to the upper receiver receiving the reflected upper detection signal indicating detection of a surface.
Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments can take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present embodiments. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures can be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.
In one example,
A lower propeller mount 54 may be mounted to the body of the flying toy doll 10 for rotation. The lower propeller mount 54 may define two or more lower receiving brackets 56 extending outward from the lower propeller mount 54. For example, the lower blade receiving brackets 56 may each define a pair of lower bracket prongs adapted to receive a lower pin 57 extending therebetween. Two or more lower blades 60 may each define a proximal end 62 and a lower extension 63 mounted to one of the lower receiving brackets 56 at the lower pin 57 for hinged movement between at least two positions.
For example,
The flying toy doll 10 may include a pair of flybar mounting brackets 80 secured to the upper propeller mount 36. Each of the flybar mounting brackets 80 may define a pair of prongs adapted to receive a flybar pin 81 extending therebetween. A flybar 84 may include first and second portions, each portion may define a proximal end adapted to mount to one of the flybar pins 81 to facilitate pivotal movement of the flybar 84 portions between at least a flybar raised position or flybar flying position and a flybar lowered position or flybar resting position. The portions of the flybar 84 may define a distal end which may be weighted to provide stability during rotation of the upper propeller mount 36.
In another example,
For example, a first propeller mount 122 may be mounted to the central shaft 114 for rotation in a first direction about the central axis 115. The first propeller mount 122 may also be mounted to the central shaft 114 for pivotal movement about at least one axis such as a first propeller mount axis defined by a set of upper receiving brackets 126. The first propeller mount 122 may define the two upper receiving brackets 126. A first set of blades 128 may be mounted to the first propeller mount 122 for pivotal movement between at least two positions. For example, each of the blades of the first set of blades 128 may define a first proximal end 130 and a first distal end 132. Each first proximal end 130 may be mounted to the respective upper receiving bracket 126. A safety arc 134 may extend from the first proximal end 130 to the first distal end 132. The safety arc 134 may assist in preventing contact with a leading edge 135, relative to rotation in the first direction, of the blades 128.
Another example of the two or more propeller assemblies 121 may include a second propeller mount 140 which may be mounted to the central shaft 114 for rotation in a second direction about the central axis 115. The second propeller mount 140 may define two or more lower receiving brackets 142. A second set of blades 144 may be mounted to the second propeller mount 140 for pivotal movement between at least two positions. For example, each of the blades of the second set of blades 144 may define a second proximal end 146 and a second distal end 148. Each second proximal end 146 may be mounted to a respective lower receiving bracket 142. A safety arc 150 may extend between the second proximal end 146 and the second distal end 148. The safety arc 150 may assist in preventing contact with a leading edge 147, relative to rotation in the second direction, of the blades 144.
A gear train 160 may mechanically link the first propeller mount 122 and the second propeller mount 140 for counter rotation. For example, the gear train 160 may link rotation such that the first propeller mount 122 and the second propeller mount 140 always rotate in opposite directions. This counter rotation may assist in providing stability of the toy
A flybar mount 170 may be mounted to the central shaft 114 for rotation in the first direction and pivotal movement. A flybar 176 may include first and second portions extending outward from the flybar mount 170. Distal ends of the first and second portions of the flybar 176 may be weighted to assist in providing stability during flight of the toy
