DETAILED DESCRIPTION OF THE DISCLOSURE

An example of a toy FIG. 10 having multiple cam-actuated moving parts, such as moving facial-expression structures, is shown in FIG. 1. Unless otherwise specified, the toy figure may contain at least one of the structures, components, functionalities, concepts, and/or variations described, illustrated, and/or incorporated herein. The multiple cam-actuated moving parts may be used to simulate a variety of emotions, attitudes, and/or feelings for the toy figure. Examples of emotions, attitudes and/or feelings may include anger, surprise, indifference, happiness, etc.

The toy figure may include a head 12, a body 14, arms 16, and legs 18, as shown in FIG. 1. The head, arms, and/or legs may be movably connected to the body. Toy FIG. 10 also may include one or more plural facial-expression structures 20, such as eyebrows 22, eyelids 24, eyeballs 26, and a mouth 28, as shown in FIG. 1.

The facial-expression structures may be movably mounted to the head, such as slidingly, pivotably, and/or rotatably mounted to the head. Additionally, or alternatively, the plural facial-expression structures may be spaced from each other and/or configured to move independent of each other. Alternatively, two or more of facial-expression structures 22 may be connected to each other and/or move dependent of each other. One or more of the facial-expression structures may move beneath a flexible “skin” of the toy figure. For example, the facial-expression structures may include eyebrow levers that move the skin to make the eyebrows appear to move when those levers are moved by a cam assembly described below.

Although toy FIG. 10 is shown to include facial-expression structures 20, the toy figure may additionally, or alternatively, include other structures movably connected to any suitable portion of the toy figure, such as the head, body, arms, legs, and/or one or more accessories. For example, wings 30 (shown in FIG. 1) may be movably connected to body 14.

Toy FIG. 10 may include a cam assembly 32, a cam follower assembly 34, a drive assembly 36, and a controller assembly 38, as shown in FIGS. 1-2. The cam assembly may include any suitable structure configured to move facial-expression structures 20. For example, cam assembly 32 may include plural cams 40 and a cam shaft 42, as shown in FIG. 2. The plural cams may be mounted on the cam shaft and configured to rotate about a first axis F defined by that shaft, and to move the plural facial-expression structures.

Cam assembly 32 may include any suitable number of cams 40. For example, the cam assembly may include five cams. Each of the cams may be configured to move a different facial-expression structure. Alternatively, one or more of the cams may move two or more facial-expression structures. Alternatively, or additionally, two or more cams may move a single facial-expression structure.

Although cam assembly 32 is shown to include five cams 40, the cam assembly may include two, three, four, six, seven, eight, or more cams. Additionally, cams 40 may have any suitable diameters. For example, the cams may have a constant outer diameter. Alternatively, two or more of cams 40 may have different outer diameters from the other cams.

Cams 40 may include a drive surface 44 and a cam profile surface 46, as shown in FIG. 2. The drive surface may be in contact with a cam drive of drive assembly 34 and may include a plurality of surface teeth 48. The teeth may mesh with drive teeth of drive assembly 34. Cam profile surface 46 may be configured to move one or more cam followers of cam follower assembly 36. The cam profile surface may include any suitable combination of shapes (such as valleys, protuberances, etc.) based, at least in part, on the desired movement of the facial-expression structure(s). For example, the cam profile surface may include at least one lobe 50.

The drive and cam profile surfaces may have any suitable outer diameters. For example, the drive surface may have outer diameter D1 and the cam profile surface may have an outer diameter D2. The outer diameter of the cam profile surface may be less than, the same, or greater than the outer diameter of the drive surface. For example, outer diameter D2 may be less than outer diameter D1 for cams 40, as shown in FIG. 2. Alternatively, outer diameter D2 may be the same as outer diameter D1. In either alternative, cams 40 may have an outer diameter that is the same as the outer diameter of the drive surface of the cams. In other words, the outer diameter of cams 40 is the same as outer diameter D1.

Alternatively, outer diameter D2 may be greater than outer diameter D1. In that alternative, cams 40 may have an outer diameter that is the same as the outer diameter of the cam profile surface of the cams. In some embodiments, one or more outer diameters of the cam profile surface of the cams may be the same and/or greater than the outer diameter of the drive surface of those cams. In those embodiments, each of cams 40 may have an outer diameter that is either the outer diameter of its drive surface or the outer diameter of its cam profile surface.

Cam follower assembly 34 may include any suitable structure configured to operatively connect cam assembly 32 and facial-expression structures 20. For example, the cam follower assembly may include plural cam followers 52 and a bias assembly 54, as shown in FIGS. 2-3. The cam followers may be configured to connect the plural facial-expression structures and the plural cams. For example, cam followers 52 may include a first end portion 56 and a second end portion 58, as shown in FIG. 3.

The first end portion may be engaged with the cam profile surface, and may be configured to be moved by the cam profile surface of the cams, as shown in FIGS. 5-6. Second end portion 58 may be connected to one or more of the facial-expression structures in any suitable way(s). Cam followers 52 may be configured to pivot about one or more pivot axes P. The pivot axis may be parallel to the first axis, or may have any other suitable relationship with the first axis, such as perpendicular or oblique to the first axis. Alternatively, or additionally, the cam followers may be slid and/or rotated by the cam profile surface of the cams.

Cam follower assembly 34 may include any suitable number of cam followers 52. For example, the cam follower assembly may include a cam follower 52 for each cam 40. In other words, cam follower assembly 34 may include the same number of cam followers as cams. Alternatively, cam follower assembly 34 may include less or more cam followers 52 than cams 40. For example, two cam followers 52 may engage the cam profile surface of the same cam 40 in different areas of that cam.

Bias assembly 54 may include one or more bias elements 60 configured to urge one or more of the cam followers into engagement with the cam profile surface of the plural cams, as shown in FIGS. 2-3. For example, bias elements 60 may urge cam followers 52 toward cam profile surface 46. Bias elements may include coil springs, leaf springs, and/or musical wire.

Any suitable number of the cam followers may be connected to one or more of the bias elements. For example, three of the cam followers may be each connected to a different bias element 60, as shown in FIGS. 2-3. Alternatively, more or fewer of the cam followers (such as one, two, four, or five) may be connected. In some embodiments, a bias element 60 may be connected to two or more of the cam followers. The cam assembly and cam follower assemblies may sometimes be referred to as a “cam-based actuating mechanism.”

Cams 40 and cam followers 52 of the cam-based actuating mechanism may be configured to be connected to any suitable combination of facial-expression structures 20. For example, cams 40 may include first cam 76, second cam 78, third cam 80, fourth cam 82, and fifth cam 84. Cam followers 52 may include first cam follower 86, second cam follower 88, third cam follower 90, fourth cam follower 92, and fifth cam follower 94, as shown in FIGS. 5-6.

Referring to FIG. 7, the first cam and cam follower combination may be configured to move, for example, eyeballs 26 between any suitable positions, such as between a left position L and a right position R. The second cam and cam follower combination may be configured to move, for example, a first eyebrow 22 between any suitable positions, such as between a high position H and a low position W. The third cam and cam follower combination may be configured to move, for example, one or more eyelids 24 between any suitable positions, such as between an up position U and a down position N. The fourth cam and cam follower combination may be configured to move, for example, mouth 28, between any suitable positions, such as between an open position O and a closed position C (or between narrow open and wide open positions). The fifth cam and cam follower combination may be configured to move, for example, a second eyebrow 22 between any suitable positions, such as between high position H and low position W.

One or more of the above cam and cam follower combinations may provide movement of one or more facial expression structures along a full range between the above described positions or among one or more discrete positions between those positions. For example, the first cam and cam follower combination may move the eyeballs along a full range between the left and right positions, or may move the eyeballs to one or more center positions (and/or other positions) between the left and right positions.

Drive assembly 36 may include any suitable structure configured to move cams 40. For example, the drive assembly may include a cam drive 62, a drive shaft 64, drive gears 66, and a motor 68, as shown in FIGS. 2-4. The cam drive may be mounted on drive shaft 64. Cam drive 62 may be configured to rotate about a second axis S defined by that shaft, and to contact and rotate plural cams 38 about the first axis. First axis F may have any suitable relationship with second axis S, such as parallel, perpendicular, oblique, etc. For example, first axis F may be spaced from and/or parallel to second axis S.

Cam drive 62 may be a single cam drive or may include multiple components. Additionally, the cam drive may be any suitable shape(s). For example, the cam drive may be elongate and/or may have a constant outer diameter D3. In some embodiments, the constant outer diameter of plural cams 38 may be larger than the constant outer diameter of cam drive 62. The cam drive may include a plurality of drive teeth 68 that may be meshed with the plurality of surface teeth of one or more of the cams, as shown in FIGS. 2-4.

Drive gears 66 may include any suitable structure configured to operatively connect motor 68 and cam drive 62. For example, drive gears 66 may include one or more worm gears 72, as shown in FIG. 4. Motor 68 may be configured to rotate cam drive 62 about the second axis via drive gears 66. The motor may be configured to rotate the cam drive in clockwise and/or counter-clockwise directions (and/or forward and/or reverse directions).

In some embodiments, drive assembly 34 may include a torque limiter or clutch 74, as shown in FIG. 4. The clutch may be configured to isolate at least a part of the drive assembly from damage, such as damage that may be caused by externally caused motions of the facial-expression structures. Clutch 74 may include friction-based, toothed, and/or castellated clutches. The cam assembly, cam follower assembly, and/or drive assembly may be disposed within head 12.

Controller assembly 38 may include any suitable structure configured to selectively control drive assembly 34. For example, controller assembly 38 may include a controller 96 and a user interface 98, as shown in FIG. 1. The controller may control motor 68 to selectively rotate cam drive 62 based, at least in part, on one or more inputs from the user interface. For example, the controller may control the motor to rotate cam drive in a clockwise or counter-clockwise direction based, at least in part, on one or more of those inputs.

User interface 98 may include any suitable structure configured to be manipulated by a user, such as one or more buttons 100 shown in FIG. 1. The user interface may include any suitable number of buttons 100, such as one, two, three, four, or five buttons. Additionally, or alternatively, user interface 98 may include one or more levers, pull cords, switches, etc.

In some embodiments, controller assembly 38 may include one or more sensors (not shown) configured to enable and/or prevent certain movements and/or movement sequences of the cam-based actuated mechanism. The sensors may be position-, orientation-, and/or motion-based sensors and may provide one or more inputs to the controller. The controller may be configured to cause the motor to rotate the cam drive to a predetermined rotational position (and/or sequentially rotate the cam drive to a predetermined sequence of a plurality of predetermined rotational positions) based on those inputs and/or inputs received from the user interface.

For example, the sensor may provide inputs to the controller regarding the position of the cams and/or facial-expression structures allowing the controller to move those facial-expression structures to the predetermined position(s) and/or sequence based on the input(s) received from the user interface. In some embodiments, controller assembly 38 may include a zeroing or centering mechanism (not shown) configured to return the facial-expression structures to one or more predetermined positions after those structures are moved.

Toy FIG. 10 may additionally, or alternatively, include one or more other assemblies, such as an audiovisual assembly (not shown) configured to generate one or more audio outputs and/or one or more visual outputs. The audio outputs may include, for example, verbal output and/or sound effects. The visual outputs may include, for example, illumination of one or more lamps or light-emitting diodes. Controller 96 may be configured to control the audiovisual assembly to synchronize the audio and/or visual outputs with movement of the facial-expression structures and/or other moving parts. For example, the controller may control the drive assembly and audiovisual assembly to generate facial-expression structure movements and audio and/or visual outputs based on which button 100 the user has pressed.
