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, but preferably is dome-shaped. The see-through housing can be constructed of a plastic material.
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/off 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.
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. The number and placement of the light sources 6, 7 along the flexible arms 5 and printed circuit board 13, respectively, may also be modified, according to the lighting display desired.
The light source assembly 20 may be made of a rigid material, such as plastic. Decorative sheets may be adhered to the outer surface of the light source assembly 20. 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.
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 are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.
