The buttons 122 and the switch 124 include any buttons or switches known in the art including momentary buttons and toggle switches, among others, which are suitable for use in activating and deactivating lights or motors housed within the base 102. The control panel 120 also includes a front panel 123 on which a label 125 is placed.
The base further includes, equally spaced at three locations around the circumference of the exterior surface of the base, recesses 126 and scallops 128. The recesses 126 extend in a lateral direction perpendicular to the height of the base 102. The recesses 126 are each configured to removably accept a marker 130. As such, a marker 130 is inserted into a recess 126 for storage while not in use.
The markers 130 comprise a dry-erase marker having ink characteristics and drawing characteristics suitable for use with the plate 104 and the dome 106. The markers 130 include an ink of a predetermined composition that does not mar or stain the plate 104 or the dome 106 after prolonged exposure or repetitive use of the markers on the plate 104 and the dome 106. Further, the markers 130 utilize an ink composition that is easily erasable from the plate 104 and the dome 106 such that drawings may be placed on the plate 104 and the dome 106 and easily erased or removed therefrom. The markers 130 are described herein as dry-erase markers so as not to distract from the explanation of embodiments of the invention, however, this is not intended to limit embodiments of the invention to use of dry-erase markers. Any compatible marking device is useable and is contemplated in embodiments of the invention.
The scallops 128 are located beneath the recesses 126 around the circumference of the base 102. The scallops 128 provide an easily graspable portion of the base 102 to allow a user to grip and lift the base 102 from a surface.
The plate 104 comprises a flat section of material having sufficient dimensions to be received by receptacle 110 of the base 102 and to fit within the interior of the dome 106. The plate 104 thus has a straight bottom edge 116 and a curved upper edge 136 that mimics the interior shape of the dome 106. In an embodiment, the curved upper edge 136 is parabolic in shape. The plate surface 132 is a broad, flat surface upon which a user uses the markers 130 to draw one or more images, pictures, or other drawings thereon (hereinafter “drawings”). In an embodiment, the plate has any desired form or shape. The plate 104 has two opposite sides, each of which comprises a flat plate surface 132 upon which a user may draw.
The dome 106 is a hollow parabolic dome having a circumference at the bottom edge 118 sufficient to be received by the channel 112 of the base 102. Alternatively, the dome 106 may have any dome shape, such as for example and not limitation, elliptical, saucer, spherical, or any other dome shape suitable for use in embodiments of the invention. The interior of the dome 106 is of sufficient size and dimension to accept the plate 104 therein. The dome 106 further includes a knob 138 located at an apex or at the top of the dome 106 on an exterior surface. The knob 138 is of any configuration suitable for use in allowing a user to grasp the knob to lift and/or rotate the dome 106 on the base 102. The dome 106 also includes an outer surface 140 on which a user places one or more drawings. The dome 106 and the plate 104 are comprised of a polycarbonate clear plastic, but may be comprised of any clear material such as, for example and not limitation, acrylics, glass, or any other suitable material. In an embodiment, the dome 106 is tinted or has one or more translucent or opaque sections.
With continued reference to FIGS. 1-3, the operation of the unit 100 is described in accordance with an embodiment of the invention. Initially, a user draws one or more drawings on the plate surface 132 of the plate 104 using the markers 130. The user also draws one or more drawings on the outer surface 140 of the dome 106. The bottom edge 116 of the plate 104 is inserted into the receptacle 110 of the base 102. The receptacle 110 accepts the bottom edge 116 of the plate 104 a sufficient distance to support the plate 104 in a generally vertical orientation. The dome 106 is placed over the plate 104 and accepts the plate 104 within the interior of the dome 106, as depicted best in FIG. 2. Also as depicted in FIG. 2, the markers 130 are coupled to the base 102 via the recesses 126 in order to store the markers 130 until later use.
A user activates one or more light sources housed within the base and exposed along a bottom surface of the channel 112 and the receptacle 110 using the buttons 122 and the switch 124. The location of the one or more lights is generally indicated in FIG. 1 at locations 142. The location of the lights with respect to the bottom edges 116 and 118 of the plate 104 and the dome 106 respectively allows the light to be transmitted into the plate 104 and the dome 106. The light is directed within the materials of the plate 104 and the dome 106 via internal reflection of the light by the material. In an embodiment, the plate 104 and the dome 106 provide total internal reflection of the light. As such, the plate 104 and the dome 106 are not substantially illuminated by the light and remain substantially dark or transparent. Further, where a user has provided drawings 134 and 144 on the surfaces 132 and 140 of the plate 104 or the dome 106 respectively the ink on the surfaces 132 and 140 is illuminated by refracting at least a portion of the light passing through the plate 104 and the dome 106 out of the plate 104 or dome 106 and provides a glowing effect. As such, when viewed in low ambient light conditions as depicted in FIG. 3, the drawings appear to glow in the dark.
The light sources included within the base 102 provide light within a predetermined spectrum or range of wavelengths that is suitable to illuminate the ink of the markers 130. Such wavelengths may be in the blue region of the visible light spectrum or any other visible or non-visible spectrums of light. As such, the lights may illuminate the ink of the markers 130 by reflection of all or a portion of the light from the ink on the plate 104 or dome 106, or the light may cause, produce, or catalyze a physical or chemical reaction in the ink which releases energy in the form of light. The light sources are light emitting diodes (LEDs), halogen lights, incandescent lights, black lights, or any other light technology. Further, the light sources may be of a single color such as blue, or may be multicolored, among various other configurations.
Lighting of the dome 106 and the plate 104 may take on many different configurations, including constant on or off of the light sources for both the plate 104 and the dome 106, intermittent lighting of the plate 104 and/or the dome 106, flashing of the lighting of the plate 104 and/or the dome 106, or strobing of the light sources. Additionally, light sources contained beneath the channel 112 may be sequenced in a marquee fashion such that one or more light sources are illuminated at a time and de-illuminated to create the effect of lights moving through the channel 112 about the circumference of the base 102.
As such, by providing drawings in a sufficient configuration about the dome 106, a perception of animation of the figures drawn thereon is provided. The buttons 122 and the switch 124 also control rotation of the dome 106 about the base 102. The buttons 122 and the switch 124 may activate one or more drive means within the base 102 that cause the dome 106 to rotate about a central axis on top of the base 102 in a clockwise or counterclockwise direction. Alternatively, the dome 106 may be rotated manually via the knob 138 at the apex of the dome 106. In another embodiment, the plate 104 is also provided with rotational motion either manually or mechanically to provide an additional source of animated viewing.
With reference now to FIGS. 4A, 4B, and 5, an illuminated-display unit 200 is described in accordance with an embodiment of the invention.

The base 202 of the illuminated-display unit 200 includes a control panel 204 having buttons 206 and a switch 208. The control panel 204 also includes a front panel 210 upon which a label is applied. The control panel 204 is configured differently from that of the control panel 120 of the unit 100 in order to provide a modified appearance to the base 202.
The base 202 also includes recesses 212 and scallops 214 as described above with respect to the unit 100. Additionally, illuminated-display unit 200 includes a plate 216 and a dome 218, also as described previously. Each of the components 202-216 of the unit 200 operate as described above with respect to the unit 100.
With reference now to FIGS. 6A and B, an illuminated-display unit 300 is described in accordance with an embodiment of the invention. Illuminated-display unit 300 includes a base 302, a plate 304, and a dome 306. The base 302 is configured to resemble a rocket ship or a spaceship and has a control panel 308, buttons 310, a switch 312, and a front panel 314. The base 302 also includes handles 316 configured to resemble fins or wings on a rocket ship or a spaceship. The handles 316 also include on an upper surface a plurality of recesses 318 extending in a lateral direction perpendicular to the height of the base 302 and configured to removably couple to one or more markers (not shown) and to retain them while not in use. Each of the components 308-318 of the base 302 function and operate similarly to those described for illuminated-display units 100 and 200.
The base 302 also includes along an upper surface 320 a thumb ring 322. The thumb ring 322 forms at least a portion of a channel (not shown) such as channel 112 of the unit 100 for receiving a bottom edge (not shown) of the dome 306. As such, the thumb ring 322 removably couples to the dome 306 when the dome 306 is placed atop the base 302. The thumb ring 322 is rotatably coupled to the base 302. Thus, a user rotates the thumb ring 322 in a clockwise or counterclockwise direction about base 302 in order to rotate the dome 306 in a clockwise or counterclockwise motion about the base 302.
The plate 304 is similar in configuration to that described with respect to plate 104 of the unit 100. The dome 306 is also similarly configured to the dome 106 of the unit 100, except that no knob is present on the dome 306.
In operation, the illuminated-display unit operates similarly to that of the unit 100, including the operation of buttons 310 and the switch 312. Illumination of the plate 304 and the dome 306 also occur similarly, and rotational movement of the dome 306 may be provided by mechanical means included in the base 302 or by manual means by manipulating the thumb ring 322.
