This disclosure relates to dolls and electronic toys. More particularly, this disclosure relates to light assemblies for dolls and toys that include a light source and one or more optical elements to diffuse or refract light, for example, to provide dynamic visual effects. The optical elements collectively define a lens assembly for a doll with an illuminated torso.
Dolls and toys may include dynamic or animated elements that provide interest during play. For example, a doll or action figure may include a light source such as a battery-powered LED. For another example, an electronic board game may include LED lights embedded in the game board and turned on or off by events occurring during game play. Such features may be controlled or animated by switches and associated electronic devices.
Examples of such systems are disclosed in U.S. Pat. No. 6,165,037, U.S. Pat. No. 6,139,394, U.S. Pat. No. 5,730,638, U.S. Pat. No. 5,672,090, U.S. Pat. No. 5,328,401, U.S. Pat. No. 5,118,319, U.S. Pat. No. 4,075,782, U.S. Pat. No. 2,605,385, and U.S. Pat. No. 1485641; and in published patent applications US20120088434, US20120052763, and W01993023128.

Examples of an illuminated doll according to the present disclosure are shown in
This disclosure describes illuminated dolls that include an internal light source and an associated optical assembly. The light source and optical assembly may be located inside the doll, e.g., within a hollow cavity of the torso of the doll. The cavity may be covered by a translucent breastplate to allow transmission of light to the viewer. A light source such as one or more light-emitting diodes (LEDs) may have an activating switch, a power supply, and associated electronics adapted to flash, dim, pulse, or otherwise modulate light emitted by the light source.
The doll may include a movable appendage, such as an arm, operatively attached to a switch that activates the light source. Raising the arm, for example, may turn on the light source, and lowering the arm may turn off the light source.
The optical assembly includes optical elements such as lenses that may be configured as one or more compound lenses. These optical elements may refract, reflect, diffract, or otherwise modify light generated by the light source. The optical elements create a sparkling, magical, dynamic visual effect displayed by the doll. For example, a light source positioned near the back of the hollow cavity may transmit light through a compound lens that modifies the light. This light may in turn pass through another compound lens that further modifies the light. This light may then pass through the breastplate. Modifying the light electronically and/or optically may create a sparkling, dazzling, playful light show, shining out of the doll, amazing and delighting a child or other viewer.
In various embodiments, the light source and/or a compound lens may be movable, e.g., so that the viewer can modify the light by moving the light source and/or compound lens within the doll. A doll may further include a sound source, such as a speaker. Electronics within the doll may play music and/or sound effects through the speaker. Sound and lighting effects may be coordinated with each other. For example, the light source may pulse to the beat of a song played by the sound source. Some embodiments may include additional features. For example, the arm that activates the light source may hold a magic wand that includes a second light source, activated in coordination with the light source and/or sound source mentioned previously.
With specific reference to
Structural elements of doll 10 may include various parts that provide functional and/or decorative form. In the representative example of
Doll 10 may have a visual display region 20, best shown in
Torso 12 of doll 10 may function as a central structure or point of attachment for appendages, such as, head 14, arms 16A and 16B, and legs. Torso 12 may be at least partly hollow. With reference also to
Cavity 22 may have an opening 24 that may have matched or fitted cover, referred to as breastplate 26. Breastplate 26 (shown in isolation in
Doll 10 may include electrical and/or electronic elements. For example, doll 10 may include a power source 30, a light source 32 connected to power source 30, a switch 36, and electronic devices 38. In some embodiments, doll 10 may also include a sound source 34, such as, a speaker.
Power source 30 or power supply 30 may be any source of electrical power, e.g., a battery. Power source 30 may be disposed within cavity 22 or elsewhere and may include a structure that allows for removing and replacing batteries. Power source 30 may include electrical conductors (not shown) to carry electrical current from power source 30 to powered devices such as light source 32. Power source 30 may include associated electrical or electronic parts, e.g., resistors or capacitors (not shown), e.g., to regulate electrical power as appropriate to light source 32, sound source 34, or other electrical parts of doll 10.
Light source 32 may be any source of visible light. For example, light source 32 may include one or more LED lights. In some embodiments, light source 32 may include an array of LEDs of a selected color or of different colors, in order to add interest to the light show generated by illuminated doll 10.
In an embodiment, light source 32 may be moveable. For example, a lever connected to light source 32 may project through the back of doll 10, allowing the viewer to move light source 32. This movement may allow for an interactive play of light at visual display region 20, for example.
Switch 36 may be any device that can activate or de-activate light source 32. For example, switch 36 may be a contact switch electrically connected to at least power source 30 and light source 32 and operatively connected to a movable first arm 16A. In this example, switch 36 may be configured to be electrically open when first arm 16A is in a lowered position, adjacent torso 12, and electrically closed when first arm 16A is in a raised position. In this configuration, lifting arm 16A may turn on light source 32, and lowering arm 16A may turn off light source 32, allowing the viewer to activate or de-activate the light show emitted by illuminated doll 10. If other powered devices such as sound source 34 are present, switch 36 may similarly control those devices.
An appendage such as arm 16A operatively connected to switch 36 may include a spring, e.g., to return the appendage and thereby switch 36 to a selected position. For example, a spring may return or bias switch 36 to an open or OFF position, except when pushed closed or ON by the viewer.
Many types of devices may function as switch 36. For example, any appendage (e.g., arm, head, leg) may be operatively connected to switch 36 and serve to activate the visual display. For example, a pressure switch 36 may be activated by squeezing a selected portion of doll 10. For another example, a timer or sound-sensitive device may function as switch 36. For yet another example, a push button on a front or back of a torso of the doll 10 may function as switch 36. An arm 16 or other structure operatively connected to switch 36 may be referred to as an actuator. Stated differently, actuator 36 operably couples arm 16 to activation of light source 32.
Doll 10 may include electronic devices 38 adapted to control light source 32 and other powered devices (if present). Electronic devices 38 (also referred to as electronics or electronic controls) may include a microprocessor or microcontroller, volatile memory such as RAM, and non-volatile memory such as flash memory. Electronic devices 38 may further include operating instructions, such as programs stored in the non-volatile memory, and data, such as light patterns, sound effects, and songs or music stored in non-volatile memory.
Non-volatile memory may be installable or updatable. For example, illuminated doll 10 may include a connector (not shown) that allows the viewer to insert a component that includes a memory that provides new program instructions or new data, such as new programmed light patterns, songs, music, or sound effects. A programmed light pattern may refer to any illumination effect obtained from light source 32, such as but not limited to turning one or more lights (e.g., individual LEDs) ON or OFF, dimming one or more lights, flashing or pulsing one or more lights, and so on.
Illuminated doll 10 includes an optical assembly 40 that transmits light emitted by light source 32 to display region 20. For example, light from a light source 32 disposed toward the back side of cavity 22 may pass through second optical layer 42, then through a first optical layer 44 adjacent breastplate 26, and then through a translucent region 48 of breastplate 26 located on a surface of torso 12 for display to the viewer. Passing light through at least one optical layer dramatically enhances the visual impact of the light show of illuminated doll 10. For example, the multiple optical elements in an optical layer may split light from each light (e.g., each LED) in light source 32 into multiple highlights. A given number of actual lights consequently may look like a larger number of lights. Three LEDs, for example, may have the decorative impact of hundreds of LEDs. Embodiments with a movable light source 32 and/or an optical layer may further increase the sense of dynamic motion in a sparkling light show.
In some embodiments, the light source 32 is at least one LED mounted to the surface of a printed circuit board (PCB). The surface of the PCB may be coated with a white optical layer, such as a white solder resist. The white optical layer may help reflect more light out the front surface of the torso 12 and help to prevent the color of the underlying PCB substrate from influencing the color of the emitted light.
An optical element 46 may be a convex lens, concave lens, prism, mirror, or other light modifier, alone or in any combination. Preferably, as shown in
First optical layer 44 may be an assembly (shown in isolation in
Stated slightly differently, first optical layer 44 is integrally molded from translucent material, including a plurality of translucent co-joined spherical bodies, as shown in
A close study of
A very effective lens assembly may be created by the combination of first optical layer 44, fixed within cavity 22, and a translucent window defined by breastplate 26. First optical layer 44 acts as a light-diffusing layer, and is formed from a plurality of co-joined spherical translucent bodies 46, as shown in
Some embodiments include a second optical layer 42 (shown in isolation in
An optical layer 42 or 44 may be configured as a loosely or densely packed array or assembly of optical elements 46. For example, elements 46 may be arranged in a dense tiled or honeycombed arrangement, so that adjacent elements 46 touch at one or more points of contact, as best shown in
Elements 46 may differ in size, e.g., to facilitate a selected packing arrangement of elements 46. For example,
An optical layer 42 or 44 may be flexible, e.g., to bend along with the flexion of a flexible doll 10. An optical layer 42 or 44 may be compared to the compound eye of an insect. The double refraction of the light through two arrays of compound lens has the effect of multiplying the surface area and visual impact created by a relatively small number of actual lights.
An optical layer 42, 44 may be referred to as a lens, refraction device, diffraction device, or light-diffusing layer. Layer 44 may form a monolayer of optical elements, embedded in a translucent binding layer. More specifically, layer 44 is a primary light-diffusing layer, preferably formed from a plurality of co-joined spherical translucent bodies 46, as shown separately in
In an embodiment, doll 10 may include structure (not shown) to allow motion of second optical layer 42. For example, second optical layer may be mounted to a flexible holder operatively connected to a lever protruding through the back of torso 12. The viewer, by moving the lever, may flex or move second optical layer 42 in relation to light source 32 and first optical layer 44. This motion may cause the highlights transmitted through breastplate 26 to dance in a lively dynamic fashion.
With reference to
In an embodiment, illuminated doll 10 may include a sound source 34 such as a speaker. Sound source 34 may be in electrical communication with electronic devices 38 and power source 30. For example, electronic devices 38 may include a sound-generating circuit capable of playing music, songs, and sound effects stored in non-volatile memory. These sounds may be coordinated with the operation of illuminated doll 10. For example, activating doll 10 by raising arm 16 to close switch 36 may trigger a rising glissando or other sound effect. For another example, sounds may be coordinated with programmed light patterns also controlled by electronic devices 38. For example, the light pattern may pulse to the beat of a song. Light patterns and songs may play for about 12 seconds, for example.
In an embodiment, illuminated doll 10 may include additional illuminated features. For example, an arm 16, that (via switch 36) energizes and activates light source 32 and/or sound source 34, may include a magic wand 50 feature that includes an additional light source 52. This second light source 52 may be coordinated with the other operations of doll 10. For example, the second light source on wand 50 may flash in conjunction with (or in opposition to) light source 32.
