Description




TECHNICAL FIELD




This application relates to actuation of a toy.




BACKGROUND




Toys that have moving parts are well known. For example, dolls and plush toys such as stuffed animals are made with moveable appendages.




SUMMARY




In one general aspect, an apparatus for a moving a toy appendage includes a moveable device within a toy appendage that is attached to a body of a toy and an actuator connected to the moveable device. The actuator is configured to rotate the moveable device about a drive axis that is fixed relative to the body of the toy. The actuator is configured to rotate at least a first portion of the moveable device relative to at least a second portion of the moveable device about a device axis that is fixed relative to the moveable device.




Implementations may include one or more of the following features. For example, the actuator may include a motor, and a drive shaft connected to the motor and to the moveable device. The drive shaft defines the drive axis. The actuator may rotate the moveable device by causing the drive shaft to rotate the moveable device. The actuator may include a lever coupled to the at least first portion of the moveable device. The actuator may rotate the at least first portion of the moveable device relative to the second portion by causing the drive shaft to rotate the lever coupled to the moveable device.




The moveable device may include a flexible strip, a plate positioned in the at least first portion of the moveable device, with the plate being transversely connected to the flexible strip, and an elongated device that intersects the plate. The lever may be connected to the elongated device such that when the drive shaft rotates the lever, the lever actuates the elongated device to exert a tension on the plate, thus rotating the at least first portion of the moveable device relative to the second portion.




The motor may be configured to rotate the at least first portion relative to the at least second portion in a first device direction about the device axis if the drive shaft is rotated in a first main direction about the drive axis. Additionally, the motor may be configured to rotate the at least first portion relative to the at least second portion in a second device direction about the device axis if the drive shaft is rotated in a second main direction about the drive axis.




The at least first portion and the at least second portion may be included in the moveable device.




The main axis may be different from the device axis.




The actuator may be configured to rotate the at least first portion relative to the at least second portion in a first device direction about the device axis if the moveable device is rotated in a first main direction about the drive axis. The actuator may be configured to rotate the at least first portion relative to the at least second portion in a second device direction about the device axis if the moveable device is rotated in a second main direction about the drive axis.




Because of the motion imparted to the moveable device and the toy appendage, the apparatus provides a realistic actuation of a toy appendage.




Other features and advantages will be apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION




Referring to

FIGS. 1-3

, a toy


100


has a body


105


and an appendage


110


connected to the body


105


. The toy


100


may be of any design, such as, for example, a doll, a plush toy such as a stuffed animal, or a robot. The body


105


of the toy


100


may be made of any suitable material. For example, if the toy is a stuffed animal, the body


105


may include a rigid internal shell surrounded by a resilient material and covered with a pile that resembles the animal's coat.




The appendage


110


includes a moveable device


115


that is actuated by an actuator


120


inside the body


105


to move the appendage


110


. The actuator


120


is powered by a power source


125


that may or may not be internal to the body


105


. In one implementation, the power source


125


may be an electric source that includes a battery. In this implementation, the battery is placed in the body


105


and may be turned off and on by a switch accessible on the body


105


.




Referring to

FIGS. 4-6

, in general, the actuator


120


is configured to rotate the moveable device


115


about a drive axis


150


that is fixed relative to the body


105


of the toy


100


. Additionally, the actuator


120


is configured to rotate at least a first portion of the moveable device


115


relative to at least a second portion of the moveable device


115


about a device axis


160


that is fixed relative to the moveable device


115


. The first portion of the moveable device


115


may be any portion of the moveable device


115


, such as, for example, portion


165


(shown in FIG.


4


). The second portion of the moveable device


115


may be any portion of the moveable device


115


that includes a portion not included in the first portion, such as, for example, portion


170


(shown in FIG.


5


).




In particular, the moveable device


115


includes a flexible strip


400


that has a first surface


405


and a second surface


410


. The flexible strip


400


may be made of any suitable material that is flexible. For example, the strip


400


may be made of a plastic that is either pliable or formed thin enough to bend. Additionally, the moveable device


115


includes at least one plate


415


, at least one of which is transversely connected to the first surface


405


. A plate


415


may be formed integrally to the flexible strip


400


during a molding process. Alternatively, a plate


415


may be formed separately from the formation of the flexible strip


400


and then attached to the flexible strip


400


using a suitable attachment technique. For example, a plate


415


may be glued to the flexible strip


400


. As another example, a plate


415


may be shaped to fit into a slot formed in the flexible strip


400


and then snap fit into the slot during assembly. At least one of the plates


415


may be detached from the first surface


405


, yet positioned near the first surface


405


.




The moveable device


115


also includes a first elongated device


420


that intersects at least one of the plates


415


. The first elongated device


420


may be made of any flexible material. In one implementation, the first elongated device


420


is made of a string that may become slack in the absence of any pulling force. In another implementation, the first elongated device


420


is made of a flexible, yet firm material such as a wire strip that may be pulled or pushed to provide tension to the device


420


.




The first elongated device


420


has a first end


422


(shown in

FIG. 6

) that is connected to the actuator


120


(portions


122


external to the body


105


are shown in

FIGS. 4-6

) and a second end


424


that is designed to engage a plate


425


positioned along the first portion


165


of the moveable device


115


, which is at the edge of the flexible strip


400


farthest from the body


105


. In this way, when the first elongated device


420


is actuated by the actuator


120


, the first elongated device


420


may be pulled toward the actuator


120


and the second end


424


engages the plate


425


. Upon engagement of the plate


425


, the flexible strip


400


bends and thus the first portion


165


is rotated in a first device direction (for example, in a direction as depicted by arrow


430


in

FIG. 4

) about the device axis


160


.




The moveable device


115


may include at least one plate


465


, at least one of which is transversely connected to the second surface


410


. Like plate


415


, the plate


465


may be formed integrally to the flexible strip


400


during a molding process. Alternatively, the plate


465


may be formed separately from the formation of the flexible strip


400


and then attached to the flexible strip


400


using a suitable attachment technique. For example, the plate


465


may be glued to the flexible strip


400


or shaped to snap fit into a slot formed in the flexible strip


400


. At least one of the plates


465


may be detached from the second surface


410


, yet positioned near the second surface


410


.




The moveable device


115


also may include a second elongated device


470


that intersects at least one of the plates


465


. Like the first elongated device


420


, the second elongated device


470


may be made of any flexible material such as string or a wire strip.




The second elongated device


470


has a first end


472


that is connected to the actuator


120


and a second end


474


that is designed to engage a plate


475


positioned along the first portion


165


of the moveable device


115


, which is at the edge of the flexible strip


400


farthest from the body


105


. In this way, when the second elongated device


470


is actuated by the actuator


120


, the second elongated device


470


may be pulled toward the actuator and the second end


474


engages the plate


475


. Upon engagement of the plate


475


, the flexible strip


400


bends and thus the first portion


165


is rotated in a second device direction (for example, in a direction as depicted by arrow


480


in

FIG. 5

) about the device axis


160


. The second device direction is different from the first device direction.




As shown, the plate


465


is offset from the plate


415


along the length of the flexible strip


400


.




Referring also to

FIG. 7

, the actuator


120


may be designed with first and second levers


700


,


705


, respectively, that are rotatable about the drive axis


150


. The levers


700


,


705


rotate simultaneously upon actuation. The actuator


120


includes a base plate


715


that positions the moveable device


115


relative to the levers


700


,


705


. The moveable device


115


may be attached to a bottom portion


720


of the base plate


715


using any suitable technique. For example, a plate


435


(

FIG. 7

) may be glued (or otherwise fastened) to the bottom portion


720


. As another example, the base plate


715


may be formed integrally to the moveable device


115


.




The base plate


715


is rotatable about the drive axis


150


such that the levers


700


,


705


rotate when the base plate


715


rotates. The base plate


715


may include a projection


735


that engages projections


740


,


745


attached to the body


105


to prevent the base plate


715


from rotating beyond positions that correspond to the positions of the projections


740


,


745


.




The base plate


715


is rotated when the levers


700


,


705


are rotated to effectuate a compound movement of the appendage


110


. If the toy


100


is a stuffed animal, then this compound movement resembles a hugging motion.




Referring to

FIGS. 8 and 9

, the actuator


120


also includes a rotating device


800


, a rotating drive


805


, and a motor


810


. The rotating device


800


is attached to the rotating drive


805


and the rotating drive


805


is integral to the motor


810


. Thus, when the motor


810


is powered, it rotates the rotating drive


805


, which in turn rotates the rotating device


800


about the drive axis


150


. The rotating device


800


has a projection


802


that engages a notch


804


in the lever


700


(as shown), lever


705


(not shown), or a structure to which levers


700


and


705


connect (not shown), to rotate the levers


700


,


705


when the motor


810


turns the rotating drive


805


. The levers


700


,


705


and the base plate


715


are secured to the rotating device


800


with any suitable attachment technique. For example, as shown, the levers


700


,


705


and the base plate


715


may be formed with holes through which a screw


812


passes and the rotating device


800


may be formed with a threaded hole


815


for receiving the screw


812


.




During operation, the motor


810


rotates the moveable device


115


in the first main direction


730


simultaneously with rotation of the first portion relative to the second portion in the first device direction


430


as shown in FIG.


4


. In particular, the motor


810


rotates the device


800


, which rotates the base plate


715


, which rotates the moveable device


115


that is attached to the base plate


715


about the drive axis


150


in the first main direction


730


. At some point during rotation of the moveable device


115


, the device


800


rotates the first lever


700


, which pulls the first elongated device


420


and engages the plate


425


, causing the first portion


165


to rotate relative to the second portion


170


about the device axis


160


in the first device direction


430


.




The device


800


may begin to rotate the first lever


700


after the moveable device


115


has finished rotating, for example, after the projection


735


engages projection


740


. In another implementation, the device


800


may begin to rotate the first lever


700


when it begins to rotate the moveable device


115


about the drive axis


150


.




During rotation of the lever


700


, the second lever


705


is rotated in a direction that reduces the tension on the second elongated device


470


, thus creating a slack in the second elongated device


470


.




When the motor


810


is reversed, it rotates the moveable device


115


in the second main direction


725


simultaneously with rotation of the first portion relative to the second portion in the second device direction


480


as shown in FIG.


5


. In particular, the motor


810


rotates the device


800


, which rotates the base plate


715


, which rotates the moveable device


115


that is attached to the base plate


715


about the drive axis


150


in the second main direction


725


. At some point during rotation of the moveable device


115


, the device


800


rotates the second lever


705


, which pulls the second elongated device


470


and engages the plate


475


, causing the first portion


165


to rotate relative to the second portion


170


about the device axis


160


in the second device direction


480


.




The device


800


may begin to rotate the second lever


705


after the moveable device


115


has finished rotating, for example, after the projection


735


engages projection


745


. In another implementation, the device


800


may begin to rotate the second lever


705


when it begins to rotate the moveable device


115


about the drive axis


150


.




During rotation of the second lever


705


, the first lever


700


is rotated in a direction that reduces the tension on the first elongated device


420


, thus creating a slack in the first elongated device


420


.




In this way, the motor


810


may be used to impart upon the appendage


110


a compound motion defined by directions


430


and


730


or by directions


480


and


725


.




Other implementations are within the scope of the following claims. For example, in another implementation, the power source


125


may be a mechanical source that includes a device that is operated by a user. For example, the mechanical source may include a string attached to the body


105


that the user pulls. As another example, the mechanical source may include a lever attached to the body


105


that the user pulls. As a further example, the mechanical source may include a dial attached to the body


105


that the user rotates.




The actuator


120


may be configured to function as described above yet implement gears and/or pulley to effectuate the compound motions.




In another implementation, if the moveable device


415


does not include plate


465


, the actuator


120


may be designed with a single lever


700


for actuating the first elongated device


420


and for moving the flexible strip in the first device direction


430


. If the moveable device


415


includes both plate


415


and plate


465


, then the actuator


120


may be designed such that levers


700


and


705


rotate independently upon actuation.




The appendage


110


may be any extension from the body


105


of the toy


100


. For example, the appendage


110


may be a leg, a hand, or an arm. As another example, the appendage may be a tail or an elongated neck. The toy


100


may be any design, including animals, humans, robots, or machines.




The plate


465


may be designed to align with the plate


415


along the length of the flexible strip


400


.




The flexible strip


400


may include one or more dividing plates


1000


positioned along the first or second surfaces


405


,


410


of the flexible strip


400


. The dividing plates


1000


are positioned to be transverse to the plates


415


and to the flexible strip


400


. In this way, the dividing plates


100


serve to strengthen the flexible strip


400


and/or prevent the flexible strip


400


from bending excessively or breaking.




To facilitate relative movement between the first portion


165


and the second portion


170


, the flexible strip


400


may have a varying thickness such that a thickness of the strip


400


nearest to the body


105


is greater than a thickness of the strip


400


farthest from the body


105


.




In another implementation, if the first elongated device


420


is made of the flexible yet firm material, then the first elongated device


420


may be actuated by the actuator


120


by being pulled toward the actuator


120


(as discussed) or by being pushed away from the actuator


120


.
