## Background
RELATED PATENTS AND PRIORITY CLAIM
This application is a continuation-in-part of design applications 29/348,117 and 29/348,118, filed on Nov. 30, 2009, now U.S. Pat. Nos. D643,969 and D643,569, respectively, which are hereby incorporated by reference.


BACKGROUND OF THE INVENTION
1. Technical Field
The invention generally relates to articles made of transparent materials, such as glass, and in particular having a one-way glass reflective surface.
2. Description of Related Art
Related art includes U.S. Pat. No. 2,339,385 to Dupler and U.S. Pat. No. 3,610,918 to Barlow.
Dupler shows a globe lamp having an opening for receiving an internal light source. There are a number of features internal and external to the globe lamp associated with the opening. For example, attached to the opening is an opaque flange 14 that extends to the external surface of the globe. Further, Dupler provides for an opaque tubular mounting sleeve 12 projecting inside the globe having an annular portion 13 and tapered ribs 15 and a flat, non-spherical portion of the globe to allow for mounting the globe on a pedestal.
Barlow shows a novelty light device having planar panels 12 held together by opaque support ribs 14 to form a cube. Barlow provides for an internal light source and opaque internal elements comprised of miniature bulbs 16, support wires for the bulbs 18, and electric wires 20; a pedestal base 10 and 32; and an electrical connector 40 to allow for rotation of the cube.

SUMMARY
An article made of one-way glass is disclosed. The reflective surface of the one-way glass faces inwardly of the article. The one-way glass article is free of internal or external ornamentation or opaque elements. The one-way glass article is also free of internal lighting and instead is illuminated by external light sources reflected within the article by the reflective surface.
The one-way glass article is different from the prior art designs. For example, both Dupler and Barlow, which are representative of the art, are lit from an internal lamp or lamps. Internal lighting as well as internal lamps represent significant differences from the one-way glass article, which relies on external light source alone, reflected within the article (because of the one-way glass reflective surface), to illuminate the article. Further, Dupler and Barlow both have opaque elements internal to their objects. In Dupler, the sleeve with its ornamentation (tapered, ribs, annular portion) and the internal lamp are opaque elements internal to the globe. In Barlow, the miniature light bulbs, support wires, electrical wires and electrical connector are all opaque elements internal to the cube. The one-way glass article is free of any internal opaque elements. Moreover, Dupler has an opaque flange attached to the external surface to the globe.
Barlow has opaque support ribs attached to the external surface of the cube. There are no opaque elements in the one-way glass article and nothing attached externally to the article.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a front view of a spherical embodiment of a one-way glass article.
FIG. 2 is a perspective view of a cube embodiment of a one-way glass article.
FIG. 3 is a cross-sectional view of the spherical embodiment of the one-way glass article of FIG. 1.
FIG. 4 is a cross-sectional view of the cube embodiment of the one-way glass article of FIG. 3.



DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, representative embodiments of the one-way glass article are shown in FIGS. 1-4. FIGS. 1 and 3 depict a spherical embodiment of the one-way glass article generally indicated at 2. As shown in FIGS. 1 and 3, the spherical embodiment of the one-way glass article 2 has a spherical skin 6 and a hollow center 4. As shown in FIG. 3, the spherical embodiment of the one-way glass article 2 is circular in cross-section with the hollow center generally indicated at 4. The skin 6 of the spherical embodiment of the one-way glass article is made of a transparent material such as glass. An inner film 8 on the skin 6 of the one-way glass article is a reflective surface. The reflective side of the reflective surface faces inwardly toward hollow portion 4 of the spherical article 2.
FIGS. 2 and 4 depict a cube embodiment of a one-way glass article generally indicated at 20. As shown in FIGS. 2 and 4, the cube embodiment of the one-way glass article 20 has six sides, one of which is designated at 22. As shown in FIG. 4, the cube embodiment of the one-way glass article 20 is square in cross section having a hollow center generally indicated at 24. The skin 26 of the cube embodiment of the one-way glass article 20 is made of transparent material such as glass. An inner film 28 on the skin 26 of the one-way glass article is a reflective surface. The reflective side of the reflective surface faces inwardly toward hollow portion 24 of the spherical article 20.
One-way glass as used in this patent refers to a transparent material, such as glass, having a reflective or mirrored surface facing one side. From the opposite side, the material is transparent. The transparent material forming the one-way glass article can be tinted various colors.
In FIGS. 3 and 4, one-way glass is shown as a skin 6 and 26 with a reflective surface formed as a film coating 8 and 28 on the interior of the article with the reflective surface facing inwardly. The article can also be made from (1) a one-way glass reflective material that is an integral piece of material and does not require a film coating on the skin, (2) one-way glass that uses a surface coating on the exterior of the article with the reflective surface facing inwardly and a transparent skin on the inside of the article, (3) a skin and a coating having a differential index of reflection to create one-way glass, or (4) equivalent structures as would be understood by a person of ordinary skill in the art.
While the instant invention has been shown and described herein in what are conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of the invention, which is therefore not to be limited to the details disclosed herein, but is to be afforded the full scope of the claims so as to embrace any and all equivalents apparatus and articles. For example, while spherical and cube embodiments are depicted, the one-way glass article can be formed in various shapes. Also, the one-way glass article can be formed as a continuous piece of one-way glass material that has a hollow center or from pieces of one-way glass attached together to form an article with a hollow center.
