Operation of the fan can be controlled remotely through atransmitter 78 held by a user and areceiver 79 associated with the track. - The track fan has a variety of benefits. When mounted on a track lighting system, the track fan provides similar functionality to that provided by a conventional ceiling fan, for example, room ventilation, air circulation, and lighting. The track fan provides significant advantages over a conventional ceiling fan. For example, the track fan can be installed in existing track systems without further wiring. The track fan can be attached to tracks on the ceiling or on a wall. The track fan does not have to be positioned in the center of the room. Multiple track fans can be attached to a track and pointed in different directions to maximize air circulation (or control air circulation in a particular pattern). The track fans can be removed when not needed by detaching the fans from the track. Track fans can be manufactured in a variety of styles and materials to match track light fixtures in order to provide a complete visually appealing fan and light combination. Track fans can be used on tracks without light fixtures where lighting is not required, for example, if a room already has a ceiling mounted overhead light fixture.
- The following description and figures illustrate the details of several implementations of fans, fan and track combinations, and track adapters. A wide variety of other implementations of fans, adapters, remote control devices, tracks, and light fixtures and combinations of them are also possible.
- FIG. 1 shows a perspective view of a
track fan 1. The track fan in this example has a fan assembly similar to many standard electric fans, in particular the fan described in U.S. Pat. No. 6,324,340. Referring also to FIG. 2, thefan assembly 19 includes afan motor 2 and acylindrical housing 3 made from, e.g., metal or plastic. Thefan motor 2 is inserted into thecylindrical housing 3 such that the face of the fan motor is flush with the front rim of thehousing 3 and thespindle 4 of the fan motor extends to the left away from thehousing 3. Thefan motor 2 is attached to the housing using a bracket, not shown. Thefan motor spindle 4 is inserted through ahole 5 in the center of a rear parabolicsafety cage piece 6. The rearsafety cage piece 6 is attached to the face of the fan motor using screws. Afan blade 7 is attached to thefan motor spindle 4. A parabolic front safety cage piece 8 is attached to therear safety cage 6, enclosing thefan blade 7 within both safety cage pieces to prevent contact with the fan blade while the fan blade is in motion. Thefan blade 7 spins freely within the safety cage and is rotated by thespindle 4 of thefan motor 2. Instead of being mounted to a base as is the fan in U.S. Pat. No. 6,324,340, thefan assembly 19 is connected to abracket 9. Thebracket 9 has twosides 10 with holes at the end of each side and a top 11 with a hole in its center. Thebracket 9 is connected to the sides of thecylindrical housing 3 usingpins 12 that are inserted through the holes in thesides 11 of thebracket 9 and through holes in the sides of thecylindrical housing 3. The bracket is attached with the pins such that thefan assembly 19 can be pivoted up and down with the pins as the pivot point. Apeg 13 is inserted up through the hole in the top 11 of thebracket 9 and connects to a track adapter 14 (FIG. 1) using anut 15. Thepeg 13 is hollow to allow wires to run from thetrack adapter 14, through the center ofpeg 13, and through a hole in the top of thecylindrical case 3 of the fan assembly as shown in FIG. 3. Thepeg 13 is connected to thebracket 9 such that the fan assembly can rotate 360 degrees with the peg as the pivot point. FIG. 3 shows a cross-sectional view of an assembled track fan and track adapter connected to anelectrical supply track 21. This view also shows how thefan motor 2 is inserted inside thecylindrical housing 3 and how thefan blade 7 is attached to thefan motor spindle 4 and enclosed within thesafety cage 16. Thepeg 13 is shown inserted through the top of the bracket and connected to atrack adapter 14 with anut 15. The fan assembly can swivel 360 degrees around thepeg 13 and can pivot up and down at thepins 12. - Unlike a standard electric fan that is electrically wired to a plug and powered by a wall outlet, the track fan is electrically connected to a
track adapter 14 as shown in FIG. 3. Track adapters can be found in a variety of styles and functional configurations that match the various styles of electrical supply tracks that are available. Some common examples of track and adapter configurations include 2-wire, 3-wire, and 2-wire wide. Most track adapters have similar designs and the track fan can be connected to any of these adapters. The following example refers to a 2-wire track adapter and track as described in U.S. Pat. No. 6,056,561. FIG. 2 of U.S. Pat. No. 6,056,651 shows an exploded view of the track adapter and a perspective view of the track. A modified version of FIG. 2 from U.S. Pat. No. 6,056,651 is represented in FIG. 4 here to show the mechanical and electrical construction of thetrack adapter 14. As described in U.S. Pat. No. 6,056,651 and referring to FIG. 4, an adapter andtrack arrangement 20 comprises atrack 21, and anadapter 14 hung on and moved along thetrack 21. - The
track 21 comprises anelongated metal casing 23, aninsulator strip 24, and two metal conducting strips 25, 26. Theinsulator strip 24 is inserted into thecasing 23. The metal conducting strips 25, 26 are bilaterally inserted into theinsulator strip 24 within the casing, and respectively retained between the flattop wall 27 and theinside flanges 28. The metalconductive strips track 21, along opposite interior walls and parallel to each other. These conductive strips form the voltage bus and neutral bus that will supply power to thetrack adapter 14 and therefore to thefan motor 2. The conductive strips 25, 26 are often wired to a power source that is controlled by a wall switch. An adapter may also be used to connect the conductive strips to a cord that has a standard plug to receive AC power from a standard wall outlet. - Track adapters are often made of plastic and are usually square in shape with a neck extending out of the top. As shown in FIG. 4 and described in U.S. Pat. No. 6,056,651, the adapter in the example we are discussing includes a
first shell 29, asecond shell 30, athird shell 31, twoelectric wires conductive metal contacts latch 36. The adapter has ahole 37 in the bottom of the shell to receive thepeg 13 from thefan assembly 19. Thepeg 13 from thefan assembly 19 is fastened to theadapter 14 using anut 15 as shown in FIG. 3. The first ends of the two electricallyconductive metal contacts metal contacts contacts electrical wires screw 38 such that theelectrical connections electrical contacts electrical wires peg 13 and through the hole in the top of thefan assembly 19 as shown in FIG. 3. The second end of one of the wires is connected to thevoltage terminal 41 of thefan motor 2. Similarly, the second end of the other wire is connected to theneutral terminal 42 of thefan motor 2. - As described in U.S. Pat. No. 6,056,651, the track fan is connected to the
electrical supply track 21 by inserting theadapter 14 through thegap 90 of the track. The adapter is retained to the inside of the positioning space in the track byflanges 43 on the neck of thetrack adapter 14. A 90-degree angle rotation of the adapter enables theelectrical contacts latch 36 locks into thegap 90 of thetrack 21 when theadapter 14 is connected to the track. Positive electrical contact is achieved between eachmetal conducting strip corresponding contact conductive strips electrical contacts fan motor 2 as shown in FIG. 3. - FIG. 5 shows a perspective view of a
track fan 1 and track light 44 fixture attached to thesame track 21. - Other features of typical electric fans could also be incorporated into the track fan. The fan assembly may include a switch to allow on\off and speed control of the fan. The fan assembly may also include a mechanism to cause the fan to oscillate from side to side automatically. The fan may include a heating unit using the principles explained in U.S. Pat. No. 6,324,340.
- When using the track fan with track lighting fixtures on the same track, it may be desirable to control the lights and fans separately. One way to accomplish this may be to fit the fan with a dual circuit track adapter to be used with a dual circuit track. A dual circuit track adapter and track are shown in detail in U.S. Pat. No. 6,203,339. FIGS. 1-3 from U.S. Pat. No. 6,203,339 are represented as FIGS. 6-8 here. The construction of the
dual circuit track 61 andadapter 62 is similar to the construction of the single circuit track and adapter described above. One difference is that the track has two voltage buses and one of the adapter's electrically conductive contacts can be positioned at one of two different heights such that it makes contact with one of the two voltage buses of the track. - As described in U.S. Pat. No. 6,203,339,
brackets 47 define a first pocket on the interior face of thefirst sidewall 52 of the track. An insulatingelement 48 resides within the pocket. A conductive metal strip forming aneutral bus 49 is carried by the insulatingelement 48.Brackets 50 define a second pocket on the interior face of theopposite sidewall 51. An insulatingelement 53 resides within the pocket. Two conductive metal strips forming first andsecond voltage buses element 53. - The adapter consists of three metal contacts. The
ground contact 54 is inserted through a slot in theneck 57 and fixed in place such that the horizontal portion of the contact rests on top of the neck. The second end of theground contact 54 is electrically grounded within theadapter housing 58. Theneutral contact 55 is inserted through a slot in theneck 57 and fixed in place such that the horizontal portion of the contact rests on top of the neck. The second end of theneutral contact 55 terminates within the adapter housing and is connected to an electrical wire. Thevoltage contact 56 is inserted through a slot in theneck 21 and is fixed in one of two vertical positions and held in place by a holding pin in the neck that inserts into one of the twoholes voltage contact 56 terminates within the adapter housing and is connected to an electrical wire. Thevoltage contact 56 is not fixed in position and can be moved up and down and held in place at one of two different heights. The second ends of the two electrical wires are connected to thevoltage terminal 41 andneutral terminal 42 of thetrack fan motor 2 respectively as described above and shown in FIG. 3. - If the track fan is to be connected to the first electrical circuit, the voltage contact is depressed to its lower position. If the track fan is to be connected to the second electrical circuit, the voltage contact is raised to its upper position.
- Since the two voltage busses of the track receive AC power from two independent sources, fixtures with adapters that have the voltage contact set to the low position will run on one power source while fixtures with adapters that have the voltage contact set to the high position will run on the other power source. By setting the voltage contact to one setting for all fans and setting the voltage contact for all lights at the other setting, the fans can be controlled separately from the light fixtures. Using a dimmer switch to control the circuit connected to the fans will also allow control of fan speed.
- FIG. 9 shows a perspective view of a track fan with a dual
circuit track adapter 62. This figure also shows an alternate design for the fan assembly. This design has thefan assembly 91 connected to anarm 64 that is connected to thetrack adapter 62. - It may also be desirable to control fans and lights separately on an existing single circuit track system so that installation and wiring of a dual circuit track is not required. Since the single circuit track provides uninterrupted power to all fixtures connected to the track, one could fit the track adapter of the track fan with a wiring adapter to allow the track fans to be wired in series to a remotely controlled switch that is part of the adaptor. To take advantage of this functionality, lighting fixtures on the same track could also include a similar wiring adapter built into the lighting fixture track adapter.
- The switch would need to be incorporated within the track adapter and wired between the electrical contacts and the electrical wires so that the circuit is broken to the fan or light fixture when the switch is off and is engaged only when the switch is engaged.
- FIG. 10 shows an example of a
wiring adapter 65. In this example, the wiring adapter would allow a three-way electrical connection to each of four electrical contacts in thetrack adapter 14. These contacts will be referred to as voltage in 63, voltage out 66, neutral in 67, andneutral out 68. FIG. 12 shows these connections. FIG. 10 shows a front and back perspective view of awiring adapter 65. FIG. 11 shows an exploded view of thewiring adapter 65. Each wiring adapter is constructed using two electrically conductive tubular screw clamps that allow wires to be inserted in either end of thetube 69 and fixed in place with ascrew 70. In this manner, an electrical connection is achieved between the wires connected to either end of thetube 69. An electricallyconductive metal post 71 is connected to the outside of thetube 69 as shown in FIG. 11. Any connection to this post is therefore electrically connected to the two wires that are connected to either end of the tube. This completes the 3-way connection. The electricallyconductive metal tubes 69 are enclosed in aninsulated housing 72 as shown in FIG. 11 such that the metal posts 71 extend through a hole in the back of theinsulated housing 72. The wiring adapter is attached to the track adapter housing and the metal posts 71 extend into holes in the side of the adapter housing. Each wiring adapter has two connections and each track adapter is fitted with two wiring adapters, one on each side, to allow a connection to all four of the track adapter contacts; voltage in 63, voltage out 66, neutral in 67, andneutral out 68. FIG. 12 shows a cross-section view of atrack adapter 14 that is connected to atrack 21 and is fitted with twowiring adapters 65. - Many ceiling fans use a remote control unit for light on\off control, fan on\off control, and fan speed control. A typical example of a remote control unit for ceiling fans is manufactured by Hunter Fan Company (Memphis, Tenn., model #27185-060) and is available at popular home improvement stores. The remote control system includes a transmitter and receiver. FIG. 13 shows a sketch of the
transmitter 78 and thereceiver 79. The remote control transmitter has buttons for light on\offcontrol 73, fan on\offcontrol 74, andfan speed control remote control receiver 79 acts as a switch and has five outgoing wires; live in 80, neutral in 81, fan out 82, light out 83, and common 84. The remote control receiver has anantenna 85 to receive the signal from thetransmitter 78. This example shows a modified version of thereceiver 79 that includes a non-electrical adapter 88 to allow the receiver to be mounted to atrack 21. - To complete the wiring of the track fan and light fixtures to the remote control system, the fixtures on the track are wired in series (by this, we do not mean that they are wired in series with the power but rather that they are wired in series for on/off switching purposes) with the remote
control receiver switch 79. The live inwire 80 of theswitch 79 is connected to one end of the tubular screw clamp that is connected to the voltage in 63 contact of thefirst track adapter 86. One end of a wire is connected to the other end of the screw clamp and the other end of this wire is connected to the first end of the voltage in screw clamp of thenext track adapter 87. This process is repeated until all track adapters have been wired in series at the voltage incontact 63. This process is repeated for the connection of the switch's neutral in 81 wire to the neutral incontacts 67 of all fixtures. In similar fashion, the switch'scommon wire 84 is connected to the neutral outcontacts 68 of all fixtures. - Using the connection method mentioned above, the fan out
wire 82 of theswitch 79 is connected to the voltage outcontact 66 of only the adapters that are connected to atrack fan assembly 1. The adapters for all track fan assemblies are then wired to each other in series at the voltage outcontact 66. Similarly, the light outwire 83 from theswitch 79 is wired to the voltage outcontact 66 of the first light fixture adapter and all light fixture adapters are then wired in series at the voltage outcontact 66. - This wiring scheme as shown in FIG. 14 allows the fans and lights to be wired on separate switch circuits within the remote control receiver. When the transmitter button for light on\off
control 73 is pressed, the remote receiver switch completes the connection between the live in 80 and light out 83 connection, thus completing the connection at the fixtures and turning the lights on. Similarly, when the fan on offcontrol 74 button is pressed, the switch completes the circuit between the live in 80 and fan out 82 contacts and allows the fans to be turned on, independently of the light fixtures. The fan speed buttons control the amount of current supplied to the fans through the switch and therefore controls fan speed. - Using this wiring method allows fans and light fixtures that are equipped with the
wiring adapter 65 to be controlled independently without the need to replace existing single circuit tracks with dual circuit tracks. After wiring, the wires would be enclosed in a plastic strip to protect the wires and to provide a uniform appearance with the track. - This example shows one possible method of connecting the fans in series (for control purposes) to one switch and connecting the lights in series (for control purposes) to a second switch by use of a wiring adapter built into the track adapter as opposed to having two circuits built into the track. This method is intended as one example to demonstrate the concept. Any suitable method of rewiring the track adapters to a switch could accomplish the same functionality.
- FIG. 15. shows a perspective view of a track fan equipped with a
track adapter 14 that is fitted withwiring adapters 65. FIG. 15 also demonstrates another alternate design for the track fan. In this design, thefan blade 7 is enclosed within thecylindrical housing 3 instead of being outside the housing and enclosed in theparabolic safety cage 16. - FIG. 16 shows a perspective view of a room equipped with
track fans 1 and tracklights 44 connected to and powered by anelectrical supply track 21. This example shows aremote control receiver 79 attached to the track and a person holding aremote control transmitter 78 used to control thefans 1 and lights 44. - Although we have described some implementation examples above, a wide variety of other implementations are within the scope of the following claims.
