Description

CROSS REFERENCE TO RELATED APPLICATION

This patent application is related to and claims priority from U.S. Provisional Patent Application Ser. No. 60/884,311 filed Jan. 10, 2007.

FIELD OF THE INVENTION

The present invention relates, in general, to novelty desk-top display items and, more particularly, this invention relates to magnetically levitated holders for displaying and keeping small useful office items readily accessible.

BACKGROUND OF THE INVENTION

Prior to the conception and development of the present invention, people have used magnetic forces to create the appearance of objects floating or levitating in space, mostly as novelty or conversation pieces. The observer's eyes will usually focus in on the space above the object looking for inconspicuous support wires. In an example of prior art, Littlefield, in U.S. Pat. No. 3,196,566 discloses using magnetic repulsion forces to display a model airplane on a flat surface such that it appears to be flying, although is was tethered to a nearly invisible horizontal thread. In U.S. Pat. No. 4,178,707, Littlefield discloses additional ways of displaying various items such that they appear to be defying gravity, this time utilizing elongated surfaces having the same magnetic polarity over the entire surface. In all cases, Littlefield's displays are just novelty displays; nothing useful is provided. In U.S. Pat. No. 2,693,788, Spatz disclosed a desk pen holder that uses magnetic repulsion to give the appearance of the major part of a pen floating without physical support, yet available to be quickly withdrawn for writing. The pen, however, is of specialized construction with built-in magnetic elements.

U.S. Pat. No. 4,901,456 discloses a transparent photo cube magnetically suspended from above and tethered to a base below. As with all of the above prior art, common non-magnetic office items are not comprehended in the design.

SUMMARY OF THE INVENTION

The present invention provides a display apparatus for suspending common office items in apparent defiance of gravity; this display apparatus includes a base, capable of stable resting on a flat horizontal surface, and a cantilever support member fixedly attached to the base with a distal end hovering substantially above the top portion of the base. At least one first permanent magnet is fixedly attached to the distal end of this cantilever support member. A holder device shaped for supporting one or more common office items is connected at an uppermost point to at least one second permanent magnet fixedly attached to the holder device such that the polarity of end facing up toward said first permanent magnet is opposite that of first permanent magnet. A substantially inconspicuous tether filament is fixedly attached to the base at one end and to the holder device with the other end.

In an alternative embodiment of the present invention, the magnets and tether are aligned along a horizontal axis, and a photograph can be displayed and rotated in apparent defiance of gravity with nothing above it.

OBJECTS OF THE INVENTION

It is, therefore, one of the primary objects of the present invention to provide an apparent gravity-defying display that also makes common office items readily accessible.

Another object of the present invention is to provide an inexpensive and attractive desk-top display that needs no power source.

Still another object of the present invention is to provide interesting and novel décor for an office desk or table.

Yet another object of the present invention is to provide a novel way to display a photograph.

In addition to the various objects and advantages of the present invention described with some degree of specificity above, it should be obvious that additional objects and advantages of the present invention will become more readily apparent to those persons who are skilled in the relevant art from the following more detailed description of the invention, particularly, when such description is taken in conjunction with the attached drawing figures and with the appended claims.

DETAILED DESCRIPTION OF A PRESENTLY PREFERRED AND ALTERNATIVE EMBODIMENT OF THE INVENTION

Prior to proceeding to the more detailed description of the present invention it should be noted that, for the sake of clarity and understanding, identical components which have identical functions have been identified with identical reference numerals throughout the several views illustrated in the drawing figures.

Referring initially to FIG. 1, a levitating business card holder apparatus 10 is displayed. There is a base 12 from which there rises a cantilever support member 14, which has at its upper end a permanent magnet 16 attached hanging over the base 12. A holding tray 18 for business cards 24 has a magnet hidden behind the cards and attached to the holding tray 18, this magnet having an upward facing pole opposite that of magnet 16, so that there is a force pulling up on the holding tray 18.

More details of the business card holder apparatus are displayed in FIG. 2. An elongated metal rod is bent to form a base 12 and a cantilever support member 14. At the end of the support 14 is a powerful permanent magnet 16, for example a Neodymium type ring magnet, typically nickel plated and axially magnetized. The magnets can be single or multiple ones stacked. Another rigid wire structure 18 is fashioned into a two-sided business card holder for displaying business cards in two opposing directions. The uppermost part of the holder structure 18 is attached to permanent magnet or metallic object 20 in vertical alignment with the overhead magnet 16. If it is a magnet, the opposite pole needs to be facing that of the overhead magnet 16. A nearly invisible tether filament 22 is connected at one end to the base 12 and to holder structure 18 at the other end. This keeps the metal or magnet 20 from being drawn all the way up to overhead magnet 16. Preferably, the holder magnet 20 is positioned to be out of sight when cards are in the holder structure 18. The observer's eye is drawn to the gap below the overhead magnet 16, and there is the appearance of floating or levitating. While a bent metal rod is described above for both the base and support member, it is obvious that many other forms would also suffice.

FIG. 3 shows another application of the present invention, in this case supporting a common ordinary pen 30. This illustrates a distinguishing feature of this invention in that magnets or metal items do not have to be imbedded in the supported object. As above, the base 12 is extended and shaped to form the cantilever support 14 holding a permanent magnet 16 at the end. The pen holder is primarily a magnet 20 with attached prongs 26. The holder could also be in the form of a tray. The magnet 20 is restrained from being drawn all the way to the overhead magnet by the nearly invisible filament 22, which is attached to the base 12 and the magnet 20 with a length long enough to have a sufficient attraction of the magnets 16 and 20, but short enough to maintain a significant gap between the two. The tether filament could be a transparent nylon material.

FIG. 4 presents a variation of the business card holder. In this design, the base 12 is a separate somewhat solid base member with the curved support rod 14 attached to the base 12. In this instance, there are dual side-by-side magnets 17 at the upper end of the support rod 14. The business card holder 18 shown here consists of two semicircular trays back-to-back but closer at the top than at the bottom. Hidden behind and between the two trays of card holder 18 are dual magnets 21. A nearly invisible tether filament 22 connects to the support rod 14 near the base 12 and to a rod connecting the trays near the base.

FIG. 5 depicts an alternative embodiment of the present invention wherein the attraction and restraining means are aligned along a horizontal axis as opposed to the vertical axis in the prior drawings. There is a base 12 with two rigid rods 15 and 19 extending horizontally 180 degrees from one another first then curving vertically. At the distal end of rod 15, a pair of permanent magnets 17, or a rectangular magnet, is attached, either fixedly or rotatably. A planar frame 26 consists of two transparent layers. Attached to the opaque side at the center of one edge are two magnets or ferrous metal objects 21. At the opposite edge 180 degrees from the magnetic or metal objects 21, a nearly invisible tether filament 22 is attached, and the other end of filament 22 is secured to the end of one rigid rod 19. In operation, two photographs back-to-back are slid in between the two transparent layers. The nature of the dual or rectangular magnets is to prevent unassisted rotation. If an observer desires to tilt the photos or rotate to see the one on the other side, he/she does so by rotating the magnets which are frictionally restrained but can be rotated readily by a person.

While a presently preferred and various alternative embodiments of the present invention have been described in sufficient detail above to enable a person skilled in the relevant art to make and use the same, it should be obvious that various other adaptations and modifications can be envisioned by those persons skilled in such art without departing from either the spirit of the invention or the scope of the appended claims.
