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 toy character includes a body, a first propeller assembly, a second propeller assembly, and a motor. The body extends in a longitudinal direction and has a longitudinal axis. The first propeller assembly is mounted to the body to rotate in a first direction about the longitudinal axis and positioned at a mid-portion of the body. The second propeller assembly is mounted to the body to rotate in a second direction about the longitudinal axis and spaced apart from 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 propeller assembly rotates in the first direction. The motor is in communication with the first and second propeller assemblies to drive rotations in the first direction and the second direction. A controller may be in communication with the motor and a mechanical switch secured at a foot portion of the body to contact a surface. The controller may be programmed to adjust a speed of the motor in response to the mechanical switch contacting a surface. The controller may be further programmed to adjust the speed of the motor in a predetermined play pattern. The controller may be further programmed to adjust the speed of the motor based on a predetermined time scale of motor outputs. A controller may be in communication with the motor and a lower sensor secured to a lower portion of the character to transmit a surface detection signal and to receive a reflected surface detection signal. The controller may be programmed to adjust a speed of the motor in response to the lower sensor receiving or not receiving the reflected surface detection signal. The controller may be further programmed to activate or deactivate the lower sensor based on receiving or not receiving the reflected surface detection signal.
A controller may be in communication with the motor and an upper sensor secured to a head of the body to transmit a surface detection signal and to receive a reflected surface detection signal. The controller may be programmed to adjust a speed of the motor in response to the upper sensor receiving or not receiving the reflected surface detection signal. The controller may be further programmed to activate or deactivate the upper sensor based on receiving or not receiving the reflected surface detection signal. The first propeller assembly may include a first pair of blades pivotally mounted to a first propeller mount, a flybar mounted to the body and offset from the first pair of blades, and a linkage mechanically linking pivotal movement of the first propeller mount and the flybar. The second propeller assembly may include a second pair of blades pivotally mounted to a second propeller mount and a third pair of blades pivotally mounted to the second propeller mount. The toy character may include a gear train and the first propeller assembly may further include a first propeller mount and a first set of blades secured thereto for pivotal movement. The second propeller assembly may further include a second propeller mount and a second set of blades secured thereto for pivotal movement. The gear train may mechanically link the first propeller mount and the second propeller mount for the counter-rotation. One of the first propeller assembly and the second propeller assembly may further include a propeller mount, a pair of blades, and a pair of safety arcs. The propeller mount may be mounted to the body for rotation. Each of the blades of the pair of blades may extend from the propeller mount and each of the blades of the pair of blades including a lead edge and a trail edge. Each of the safety arcs of the pair of safety arcs may be spaced forward of the lead edge extending from the lead edge at a location adjacent the propeller mount to a portion of a distal end of the blade such that a space is defined between the safety arc and the portion of the distal end of the blade. A controller may be in communication with the motor to send control signals and receive voltage feedback signals. The controller may be programmed to adjust a speed of the motor in response to receiving the voltage feedback signals. The toy character may further include at least one of a sensor and a mechanical switch. The controller may be in communication with the at least one of the sensor and the mechanical switch and programmed to activate or deactivate the at least one of the sensor and mechanical switch in response to the voltage feedback signals.
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
