DETAILED DESCRIPTION OF THE PRESENT INVENTIONFIG. 1 illustrates an oblique top view of one embodiment of a presentinvention display device20 attached to aceiling fan1.FIG. 2 shows a bottom view of thepresent invention device20 shown inFIG. 1.FIG. 3 shows a side view of the present invention device shown inFIGS. 1 and 2. These three Figures are discussed collectively, with identical components being identically numbered.
Ceiling fan1 has acap3 with wiring to a power source (not shown) and to a switch (not shown). There is asupport rod5 with astationary motor housing7 and astationary hub11.Fan blades15,17 and19 are driven by the electric motor about a, central axis (extend down from support rod5), as in any conventional ceiling fan. Extending fromhub11 is a component of thepresent invention device20, namely,attachment member21. This has a bolt, weld, socket or other attachment means at its top. Often, hubs have securing nuts, and a properly orificed angle iron extending upwardly at the top ofattachment member21 would be both a sufficient and an efficient attachment component. It could be designed to fit onto the hub nut rod and the same nut might be used. Other attachment means, as mentioned, could be used alternatively. There is a swivel joint23 located at the bottom ofattachment member21. This swivel joint23 could be a universal joint, a ball and socket joint, a floating pin joint, or any other swivel mechanism that would permit a rotatable member to spin while connected to the stationary attachment mechanism.
Below swivel joint23 is aframe25 formed of cross-members as shown.Frame25 has four vanes evenly spaced, all tilted in the same direction. Thesevanes31,33,35 and37 may be unistructurally formed with the frame25 (molded all as a single piece). Theframe25 has vertical supports, such assupport27, and hassign member29 attached thereto. These are arcuated sign members that may be removable or permanent, and carry messages, artwork, drawings, photos, logos, advertising or pictures, such astext41.
Whenfan1 is turned on andblades15,17 and19 rotate, the air driven downward blows onvanes31,33,35 and37, causing the frame and its attachment (vanes and sign members) to rotate, creating a continuous scene or message.
FIGS. 4, 5 and6 show an alternative embodimentpresent invention device80. The Figures are described herein collectively.
Ceiling fan60 is similar toceiling fan1 in the preceding Figures. It has asupport rod65, amotor housing67, ahub69 andblades75,77 and79.
Present inventiondevice attachment member81 is attached tohub69 at its top and to swivel joint83 at its bottom. Below swivel joint83 is a frame with fourvertical panels85,87,89 and91. Each has at least one hole or orifice (as shown inFIG. 5) to reduce drag. There is asingle vane95 that assures direction of rotation, and thevertical panels85,87,89 and91 function both as frame and vane.Circular sign99 is permanently or temporarily attached to the frame and has amessage97. When the fan is on, the sign rotates.
FIG. 7 shows a blow up of swivel joint83. It has a bracket with a fixed eyelet on top and a rotating eyelet on the bottom; otherwise, the components are numbered identically with the preceding description.
FIG. 8 shows a bottom partial view of another presentinvention display device100. It has a hexagon configuration with framevertical boards101,103,105,107,109 and111, andspokes113,115,117,119,121 and123. Different pictures, messages or other presentations could be applied to the outside surfaces of each of theboards101,103,105,107,109 and111.
FIG. 9 shows a bottom view of another present invention display device130, with a single verticaloval frame131 withcross-member spokes133 and135. One or two messages or other signage could be presented on the outside ofoval frame131.
FIG. 10 shows that asingle frame member160 could be molded of two intersectingrods161 and163, with two opposingvanes165 and167 (not shown, but both tilted clockwise).
FIG. 11 shows a presentinvention display device220 suspended from awall250, in the vicinity of anair egress vent251, withlouvers252. There is a horizontal,support member263, connected to wall250 viaflange261. At theopposite end211 isstationary attachment member221, with swivel joint223.Frame225 has vertical sign supports, such asvertical sign support227, and hasvanes231,233,235 and237.
Circular sign229 is connected to the vertical sign supports and has amessage241. When air exitsvent251, it blows on the vanes, rotating the frame, vanes and sign for an attractive continuous presentation. The rate of rotation may be regulated by the rate of air flow, the size of the vanes, the number of vanes, the angle of vanes, the friction at the swivel joint, the resistance of the sign (if any), or any combination of the foregoing.
FIG. 12 illustrates an oblique view of another embodiment of a present invention device wherein the frame has an upper frame (vane frame) and a lower frame (sign frame) suspended from it, connected to a ceiling fan.FIG. 14 shows more detail of the upper frame. The ceiling fan has acap359 with wiring to a power source (not shown) and to a switch (not shown). There is support rod354 withstationary motor housing351 and a stationary hub underneath it. Fan blades, such asblade355, are driven by the electric motor about a central axis (extend down from support rod350) as in any conventional ceiling fan. Extending from the hub is a component of thepresent invention device300, namely,attachment323. This has an attachment means at its top to connect it to the hub. There is a swivel joint321 located at the bottom ofattachment member323 and is connected to frameconnector319. This swivel joint321 could be a universal joint, a ball and socket joint, a floating pin joint, or any other swivel mechanism that would permit a rotatable member to spin while connected to the stationary attachment mechanism.
Below swivel joint321 andconnector319 is an upper frame formed ofcross-members309 and311, as shown. There are fourvanes313,333,353 and373 evenly spaced and all tilted in the same direction. (These vanes are unistructurally formed with the frame, that is, molded all as a single piece, as shown inFIG. 14.) The frame hasflexible support cords305 and307, at the bottom of which islower frame301. Sign303 is attached to thelower frame301. When the fan blades rotate, the air drives the vanes and upper frame and the lower frame is likewise rotated. This embodiment is especially useful for very high ceiling fans wherein the sign itself is rotated, e.g., seven or eight feet from a floor. The sign may be removable or permanent, and may carry messages, artwork, drawings, photos, logos, advertising or pictures (not shown).
FIG. 13 shows the same presentinvention display device300 and identical parts are identically numbered, except that heredevice300 is suspended fromceiling vent371.
FIG. 15 shows a present invention display device with multiple display units with a plurality of them being planetary units.
Ceiling fan459 includes asupport457, a motor housing andhub451, and blades such asblade455. Suspended from the ceiling fan hub ismain attachment member423, with swivel joint421 connecting it to a frame ofcross-sections409 and411, having vanes, such as vane413.Support members405 an407 hang therefrom tomain frame401.Support members405 and407 may be synthetic or natural and may be flexible, semi-flexible or rigid.
Connected tomain frame401 is a circularvertical member403 that serves both as a sign support and as a connector to evenly spacedseparate display units461,471,481 and491. These units are structurally identical but may carry different messages. Each is characterized by the description of unit461. Each has anattachment member469, a swivel joint467 and a frame463 with one ormore vanes465. Each unit rotates about an axis of its attachment member, and simultaneously revolves about the track of the circular vertical member, when the fan is on. Hence, these four lower units, like the solar system planets, both rotate and revolve, and are planetary.
The terms “sign” and “message” as used herein should be construed broadly to mean something to be seen or read to communicate. This would include words, numbers, pictures, symbols, logos, religious representations, codes, icons, etc. The most common would be advertising signs, direction signs and holiday representations, e.g., “Eat At Sam's”, “Customer Service Here” and a pictorial Fourth of July Stars and Stripes, respectively.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
