RELATED APPLICATIONS

The present application is related to U.S. patent application Ser. No. 11/440,451, which claims priority to provisional application No. 60/684,208, the entirety of both applications being incorporated by reference herein.

FIELD

The present invention relates to a novelty light-up toy which includes an assembly including a plurality of rotating illumination sources, which form a variety of light patterns during operation, a fan extending from the assembly, and a plurality of particles that move about the toy during operation.

BACKGROUND

There are known types of novelty items or toys that have lights that spin and are selectively turned on and off in patterns, some of which are mentioned in the copending application Ser. No. 11/440,451. Other prior art patents and publications set forth the concept of particles simulating snow flakes that are circulated within a globe by a fluid impeller or fan that drives to fluid. The fluid may be liquid or air in various of the documents.
For example, U.S. Pat. No. 5,502,908 to Powell et al. relates to an animated displaying having a display chamber 14 within which are particles 16 that are propelled throughout the chamber to stimulate snow. A fan 26 draws air into the chamber and the fan 24 provides additional lifting force to the particles creating an animated blizzard.
U.S. Pat. No. 5,919,078 to Cassidy is a toy vacuum cleaner having polystyrene beads 60 that circulate due to a fan 40 between a cone 28 and an outer transparent container 20 to stimulate dust and/or dirt.
U.S. Pat. No. 6,282,820 to White et al. is a snow globe that includes particles 2 that are dispensed throughout the globe by a circulating fluid 3 that apparently is water (since a “watertight” seal is provided between the base and the globe enclosure).

DETAILED DESCRIPTION

The invention will be described in general with reference to FIGS. 1-7, which illustrate various embodiments of the novelty light-up toy 1 according to the present invention. Referring now in detail to the drawings, FIG. 1 illustrates a side view of the light-up toy 1, in accordance with one embodiment of the present invention, which includes a see-through housing 4 that permits a three-dimensional view of the rotating light source assembly when the toy is in use. The housing 4 can be in any desired shape, for example, dome-shaped. Other shapes are possible, within the scope of the invention, including a snowman shape, Santa Claus shape, and the like.
Disposed within the housing 4 is a rotatably mounted light source assembly 20 comprised of a wing portion 3 and an arch portion 2 extending from one end of the wing portion 3. The light source assembly 20 comprises a printed circuit board 13 disposed therein. The printed circuit board 13 has a shape that fits within the light source assembly 20. Affixed to the printed circuit board 13 is a series of light sources 7 designed to illuminate when the light source assembly 20 rotates. The light sources 7 may be comprised of light emitting diodes, or other suitable light sources. The light sources 7 may be provided in a plurality of colors to create a colorful visual effect. The printed circuit board 13 includes an integrated circuit (IC, not shown), which includes a program to cause the light sources 7 to light up at different intensities and different intervals, causing patterns to appear in the light as the light source assembly 20 rotates. The IC is an off the shelf component, which can be purchased, for example, from MUPAC Development Ltd., in Hong Kong, China, model # MD—264.
An additional pair of light sources 6 is found at the ends of two flexible, rotatable arms 5. These arms 5, preferably constructed of PVC or similar flexible, or semi-flexible material, are located directly beneath the housing 4 of the toy. Disposed within the handle 8 according to the embodiments in FIGS. 4 and 7 is a printed circuit board 34, which controls operation of the motor 12. In one embodiment illustrated in FIG. 4, the light source assembly 20 is connected to the motor shaft 22, so that the light source assembly 20 rotates when the motor is turn on by the on/off switch 9. In another embodiment illustrated in FIG. 7, both the flexible arms 5 and the light source assembly 20 are connected to a series of gears 14 and a motor 12, which cause the arms 5 and light source assembly 20 to rotate upon activation of an on/oft switch 9 (shown in FIG. 1). The arms 5 may be different lengths so that as the arms rotate, an oval appearance of the lights sources 6 is created.
As seen for example in FIG. 1, the on/off switch 9 is located on the handle 8 of the toy 1. The handle 8 may be further enhanced with a series of corrugated ridges 10 or other similar grip-facilitating features. The handle may be made of a rigid plastic material, or another similar suitable material.
Disposed within the handle 8 is a power source 25 for the toy 1, as well as the motor 12 that rotates the light source assembly 20 and the flexible arms 5. Preferably, the power source 25 comprises several batteries 15 (FIG. 7), although alternate sources are also possible. As shown in the embodiments of FIGS. 4 and 7, the batteries 15 are located alongside and below the motor 12. As seen most clearly in FIG. 4, wire 30 connects the motor 12 to the battery contact 32. In the embodiment shown in FIG. 4, the motor shaft 24 is connected to an armature 26, which in turn is connected to the light source assembly 20 (see, e.g., FIG. 5). The armature is connected to the motor shaft contact 27, which is in turn connected to the motor 12 via wire 28, which is in turn connected to the motor 12 via wire 28, so that the light source assembly 20 rotates when the motor is turned on by the on/off switch 9.
Alternatively, in the embodiment shown in FIG. 7, directly above and in contact with the power source 20 and motor 12 is a series of gears 14 that permit rotation of the light source assembly 20 and the flexible arms 5. The gears 14 rotate upon the user's activation of the on/off switch 9 on the exterior portion of the handle 8. Placing the switch 9 in the on position closes the circuitry connecting the batteries 15 to the motor 12. The motor 12 then causes the gears 14 to rotate, which in turn rotates the light source assembly 20 and the flexible, rotatable arms 5. Simultaneously, the light sources 7 disposed along the arch 2 and wing 3 portions of the light source assembly 20, as well as those light sources 6 at the ends of the flexible arms 5 illuminate, creating a Saturn-like light display. According to the present invention, the arms 5, the housing 4, and the light source assembly 20 all spin together at the same time. This allows for cost efficiency and also provides a unique visual effect.
According to one embodiment, the handle portion 8 holds 3 AAA batteries. However, other battery configurations are possible.
It is also a preferred embodiment of the present invention that the flexible arms 5 have a single light source 6 disposed only at their ends. The light sources 6 may be light emitting diodes or other similar devices. However, the invention also contemplates the use and placement of additional light sources 6 along the length of the flexible arms 5, or more than two arms, if a more complex lighting display pattern is desired.
The printed circuit board 13 is shown in FIG. 5 as having a half-arch shape (arch 2), extending from a wing 3 at one end thereof. However, the “arch 2 and wing 3” configuration of the light source assembly 20 within the dome 4 may be modified. FIG. 6 is an alternative embodiment of the toy 1 in which the light source assembly 20′ has a wing 3′, a connecting section 30 having one end connected to one of the wing 3′, and an arch 2′ extending from the second end of the connecting section 30. As in the embodiment of FIG. 5, the printed circuit board (not shown) is shaped to fit within the light source assembly 20′.
Another embodiment of the handle is shown in FIGS. 8-10. In this embodiment, the front handle body 101 includes a recess 112 in which the on/off button 103 sits. Inside the recess 112 is a through-hole 114, through which the slide switch 104 passes when the handle is assembled. The two halves of the handle body, front handle body 101 and back handle body 102 are assembled with all of the parts placed in the respective cavities (as will be described), and the handle bodies are fixed together using screws (not shown) that are inserted into the protrusions 150 and 152 and tightened until the handle is securely closed.
The slide switch 104 includes a peg 118 protruding from one side (FIG. 8) and a contact pad 120 protruding from the other side (FIG. 9). On an inner side of the button 103 is a seat 116 (FIG. 9), into which the peg 118 formed on one side of the switch 104 (FIG. 8) is inserted. The contact pad 120 comes into contact with the printed circuit board 105. The printed circuit board 105 is connected, via wire 122, to the motor 106. The motor 106 sits on motor seat 134 when the handle is assembled. The printed circuit board 105 fits in the handle between the motor 106 and a top contact plate 128.
Similarly to the embodiment shown in FIG. 4, the motor shaft 124 is connected to an armature (not shown), which in turn is connected to the light source assembly 20 (see, e.g., FIG. 5). The armature is connected to the motor shaft contact 107, which is in turn connected to the motor 106 via wire 126.
The top contact plate 128 forms the top of the battery compartment 136. A battery chamber divider 109 is provided to separate the battery compartment 136 into separate chambers, one for each battery 108. A battery door 110 is removably connected via a screw (not shown) that can be inserted and tightened in corresponding openings 138 and 140 in the battery door 110 and back handle body 102, respectively.
As seen in FIG. 8, the contact plate 128 is connected via wire 130 to the motor 106. A bottom contact plate 144 is positioned at the bottom of the battery compartment 136 and is connected via wire 132 to the printed circuit board 105. A wire 142 connects the bottom of the top contact plate 128 where one of the batteries contacts the contact plate 128, to the top of the contact plate 128. The wires 130, 132, and 142 serve to electrically connect the power source (in this case, three batteries) to the motor 106 and printed circuit board 105, so as to provide them with power when the on/off switch 103 is turned on.
FIGS. 10A-B are perspective views of the handle in accordance with the embodiment shown in FIG. 8. FIGS. 10C-G are plan views of the handle in accordance with the embodiment shown in FIG. 8.
FIGS. 11 and 12 illustrate improvements over the embodiments of FIGS. 11-10, in which the toy includes not only the rotating light sources, but a fan that blows particles contained in the housing around to simulate snow fall. In particular, FIG. 11 illustrates a hand-held toy according to another embodiment of the invention. A base or handle 201 is included, which can be the same as handle 101 or handle 10 shown in FIGS. 1-11. The construction of the handle 201 and the components within the handle to rotate the light source assembly 220 will not be repeated here, since the components and operation thereof are the same for this embodiment as for the embodiments discussed above.
According to one embodiment, the light source assembly 220 is in the shape of a Christmas tree, and may be covered by a green decorative sheet oil both sides. Alternative configurations, such as a Santa Clause, or snowman, are also within the scope of the invention. The light source assembly 220 may be constructed of two halves made of a rigid material, such as plastic, which hold a printed circuit board (not shown) between them. Light sources 222 are connected to the printed circuit board and extend from the printed circuit board toward the outside of the light assembly, similarly to the light sources described above with respect to FIGS. 1-10.
Also extending outwardly from the light assembly 220 is a fan 240. The fan 240 may be made of a clear plastic, light weight sheet, such as a polyvinyl chloride (PVC) sheets. The fan 240 is shown in a circular shape, but can be any shape within the scope of the invention.
Particles 230 are contained within the see-through housing 4. Particles 230 may be bead shaped, or flat, and are made of a light weight material, such as vacuum metallized PVC, or Styrofoam®. The housing 4 contains only air; no liquid is provided. Because the particles 230 are light-weight, when the light assembly 220 rotates, when the toy is operated, the particles 230 are blown around the housing 4, simulating a snowfall effect.
Another embodiment is shown in FIG. 12, which is a music box 200. In particular, an electronic or mechanical tabletop musical novelty device with synchronized light source and spinning Christmas holiday scene is provided, with particles, such as beads, blown around to depict the illusion of snow. Inside the housing portion may be a series of pictorial elements (not shown), such as snowmen, Christmas trees or the like. A light source assembly is rotatably provided in the center of the housing, which includes a plurality of spinning LEDs or other light sources that illuminate the pictorial elements inside the housing portion. Located underneath the unit is the electronic or mechanical electronic on/off switch.
According to one embodiment as shown in FIG. 12, on top of the base 202 is a see-through housing 204, similar to the housing 4 discussed above. The base 202 includes a music assembly 250. Music assembly 250 is a conventional music box assembly, which can be turned on by means of a switch (not shown) located on the bottom of the base 202. Although in one embodiment, the music assembly is operated by a separate switch located on the bottom of the base 202 (not shown) than the switch that operates the light source assembly 220 (also located on the bottom of the base 202 and not shown), the music assembly 250 may be operatively connected to the light source assembly 220 so that one switch turns both devices on synchronously.
Although all the figures show a dome-shaped housing portion 4, it is certainly possible to utilize an alternate shape, such as a pyramid, and perhaps a transparent but colored dome 4 or pyramid, so long as the shape and color allow the user a 3-D view of the printed circuit board 13 and light sources 7, or the light source assembly 220. The number and placement of the light sources 6, 7, 222 along the flexible arms 5 and printed circuit board 13 or connected to the assembly 220, respectively, may also be modified, according to the lighting display desired.
The light source assemblies 20, 220 may be made of a rigid material, such as plastic. Decorative sheets may be adhered to the outer surface of the light source assemblies 20, 220. These sheets can be solid opaque film sheets or they could be in the form of images or patterns. In addition, without departing from the inventive design, the decorative sheets can be omitted in their entirety. In this case, during the rotation the light patterns would appear to be free floating within the housing.
In the embodiments of FIGS. 11 and 12, because the fan is provided as a clear sheet extending outwardly from the light source assembly 220, there is no need for a separate fan and motor to cause the particles 230 to move about the housing, to simulate snow fall. This reduces the cost and eases the difficulty of manufacture. Additionally, because the particles are blown about the housing in the air, without the need for a liquid such as water, there is no risk that the liquid will leak if the housing develops a crack or breaks. Further, because the particles are blown about the housing by the fan, they will keep blowing as long as the switch is activated. This improves the effect over the prior art snow globes where the globe is shaken to make the snow move about the housing. Further, with the right material, the light reflects off of the flying particles, thus creating a pleasing light display.
Although various features of the invention have been described with particular embodiments. It is considered within one of ordinary skill in the art to mix and match the features in other embodiments not depicted in the figures.
The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without undue experimentation and without departing from the generic concept, and, therefore, such adaptations and modifications should and arc intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. The means, materials, and steps for carrying out various disclosed functions may take a variety of alternative forms without departing from the invention.
Thus the expressions “means to . . . ” and “means for . . . ”, or any method step language, as may be found in the specification above and/or in the claims below, followed by a functional statement, are intended to define and cover whatever structural, physical, chemical or electrical element or structure, or whatever method step, which may now or in the future exist which carries out the recited function, whether or not precisely equivalent to the embodiment or embodiments disclosed in the specification above, i.e., other means or steps for carrying out the same functions can be used; and it is intended that such expressions be given their broadest interpretation.
