## Background
FIELD OF THE INVENTION
The present invention generally relates to vehicle lighting. More particularly, the invention concerns an illuminated motorcycle exhaust.
BACKGROUND OF THE INVENTION
The popularity of motorcycling continues to increase. Riders are attracted to the freedom of the open road, leaving behind the cares and worries of everyday life. Motorcycle manufacturers have seized upon the recent surge in popularity and have been selling motorcycles and accessories in record numbers.
While luring riders with their freedom and performance, motorcycles are substantially more dangerous than automobiles. A motorcycle rider almost always fares much worse than an automobile driver when an accident between the two vehicles occurs. With the increase in motorcycle popularity, has come an increase in motorcycle accidents. In response, some states have mandated that motorcycle riders must wear helmets, and also suggest that they wear reflective vests and protective clothing.
Motorcycle manufacturers have also introduced several safety features aimed at increasing safety. For example, motorcycle headlights are always illuminated, day or night. Brake performance has improved, decreasing braking distances, and tire reliability has reduced blow-out incidents. Still, statistics show that motorcycles continue to be many times more dangerous than automobiles.
Therefore, there exists a need for an apparatus that improves motorcycle safety, while also improving motorcycle aesthetics.

As used herein, the “present invention” refers to any one of the embodiments of the invention described herein, and any equivalents. Furthermore, reference to various feature(s) of the “present invention” throughout this document does not mean that all claimed embodiments or methods must include the referenced feature(s).
The present invention provides an integrated motorcycle exhaust tip that includes a turn signal assembly that includes both turn-signals, brake lights, and running lights integrated into the motorcycle exhaust tip. One feature of the present invention is that the manufacturer installed turn signal lights may be eliminated. Alternatively, for those motorcycle owners who wish to increase safety by increasing their “conspicuity” (i.e., their visibility), the additional lights provided by the illuminateable motorcycle exhaust apparatus 15 provide additional warning to motorists.
Motorcycles have been in production for over 100 years, built by manufacturers such as Aprilla, BMW, Buell, Ducati, Harley-Davidson, Honda, Indian, Kawasaki, Moto Guzzi, Suzuki, Triumph, Victory, Yamaha, and others. It will be appreciated that the present invention may be installed on any motorcycle built by the above-listed manufacturers, or other un-named manufacturers (some, or all of the above-listed manufacturer names may be registered trademarks of their respective owners).
One manufacturer that has become very popular in the United States, as well as through-out the world, is Harley-Davidson. Harley-Davidson manufactures many different models of motorcycles, which may be generally categorized into five different types: Touring models, Softail models, Sportster models, Dyna Glide models, and V-Rod models (Harley-Davidson is a registered trademark of H-D Michigan, Inc., of Arm Arbor Mich.).
For example, touring models may include the FLHT Electra Glide standard, FLHTC Electra Glide classic, FLHTCU Ultra Classic Electra Glide, FLHTP Electra Glide police, FLHS Electra Glide sport, FLHR Road King, FLHRC Road King classic, FLHP Road King police, FLTC Tour Glide classic, FLTCU Ultra classic tour Glide, FLTR Road Glide, FLHRS Road King custom, FLHRI Road King, FLHRSI Road King custom, FLHRCI Road King classic, FLTRI Road Glide, FLHTI Electra Glide standard, FLHTCI Electra Glide classic, and the FLHTCUI Ultra Classic Electra Glide (some or all of the above model names may be registered trademarks of H-D Michigan, Inc., of Ann Arbor Mich.).

Clearly, Harley-Davidson manufactures many different motorcycle models. It will be appreciated that the present invention may be installed on any of the above-listed models, or on other models yet to be manufactured. In addition, the present invention may be installed on a “custom” motorcycle, which is a motorcycle that differs from a manufacturer-produced model. For example, a custom motorcycle may be a Harley-Davidson FXST Softail Standard that has had specific parts either added, removed or modified. Or, a custom motorcycle may be built from scratch, using no, or very few pre-manufactured parts, such as only the engine, transmission and tires.
Whether a motorcycle is custom, or manufactured by Harley-Davidson or another manufacturer, it generally includes turn-signal lights, or turn indicators that warn other motorists of the motorcycle riders' intention to turn. The turn-signal lights, which may comprise a single light or two or more lights, are generally mounted in pairs, with a left and right turn indicator pair facing forward to alert on-coming traffic, and a second left and right turn indicator pair facing rearward to alert traffic that is behind the motorcycle. On some motorcycle models, the left and right turn indicator pair facing rearward also can provide a brake light function and a running light function. That is, at night, or even during daylight hours, a running light function constantly illuminates the rear-facing lights, and a brake light function illuminates the rear-facing lights when the motorcycle's brakes are applied.
In addition, whether a motorcycle is custom, or manufactured by Harley-Davidson or another manufacturer, it generally includes at least one exhaust pipe that directs the exhaust gasses from the motorcycle's engine toward the rear of the motorcycle. Most motorcycles have a pair of exhaust pipes, with one exhaust located on either side of the motorcycle, each having a distal end, or exhaust pipe tip that is directed toward the rear of the motorcycle.
For example, FIG. 1 illustrates a rear portion of a motorcycle 2 that includes a rear tire 5 and two exhaust pipes 10. Removeably attached to the tip of each exhaust pipe 10 is an illuminateable motorcycle exhaust apparatus (“IMEA”) 15 that embodies principals of the invention. One feature of the IMEA 15 is that it includes a light assembly 20 that can replace, or augment the brake light(s) and the left and right turn indicator lights facing rearward that provide turn indicator, brake and running light functions.
Referring now to FIGS. 1-5, the IMEA 15 includes an integrated light assembly 20. The light assembly includes a lens 25 that may be clear (i.e., substantially transparent), or it may be opaque, tinted or “smoked.” It will be appreciated by those skilled in the art that the tint may be virtually any color, such as red, yellow, blue or any other desired color.
As shown in FIGS. 2 and 3, the light assembly 20 includes one or more lights 30. In a preferred embodiment, the lights 30 comprise a plurality of light emitting diodes (LEDs) with each LED capable of emitting either a red or an amber, or yellow light. Other embodiments of the lights 30 may comprise one or more incandescent lights, halogen lights, fluorescent lights, or any other type of device that emits electromagnetic radiation that is perceived by the human eye.
Also shown in FIGS. 2 and 3 is the thermal insulator 35 that is positioned on both sides of the lights 30. In a preferred embodiment, the thermal insulator comprises a ceramic fiber combined with various binders. For example, the thermal insulator may be KAOWOOL Flex-Wrap manufactured by Morgan Thermal Ceramics (KAOWOOL is a registered trademark of Thermal Ceramics Inc., of Augusta, Ga.). It will be appreciated that other types of thermal insulators may be employed.
The lights 30 are connected to wiring connector 40 that is coupled to the motorcycle wiring harness (not shown) that provides electricity to the lights 30. For example, the lights 30 may be coupled to the turn signal switch that activates the turn indicator lights (not shown) on the motorcycle. In one embodiment of the IMEA 15, the wiring connector employs a commonly available three (3) or six (6), or other, pin connector that is well known to those skilled in the art. During installation, the connector on the motorcycle wiring harness for the brake and/or turn signal indicator is un-plugged, and the respective connector 40 is plugged into the wiring harness. In this way the brake, running, and turn indicator light functions of the IMEA 15 are enabled.
It will be appreciated that other arrangements for electrically powering the IMEA 15 may be employed. For example, the lights 30 may be turned on when the motorcycle headlight is turned on, or the lights 30 may be activated by a separate switch mounted on the motorcycle that enables illumination of the lights 30 at any time, as desired by the motorcycle operator.
For example, a motorcycle rider, wishing to turn, activates a turn signal switch or other mechanism on the motorcycle 2. The turn signal switch activates the lights 30 located in the IMEA 15 that is mounted on the same side of the motorcycle 2 as the desired turning direction. In addition, the lights 30 may be activated in a flashing, strobe or other type of illumination pattern.
Referring now to FIGS. 1-5, the IMEA 15 comprises a light assembly housing element sized to be removeably coupled to a distal end of a motorcycle exhaust 10. The light assembly housing element comprises a first outer surface 45 having a first outer circumference. As shown in FIG. 1, the wiring connector 40 extends from the first outer surface 45. A second outer surface 50 having a second outer circumference is directly adjacent to the first outer surface 45. A third outer surface 55 having a third outer circumference is opposite the second outer surface 50. That is, as shown in FIG. 2, the first outer surface 45 is located between the second outer surface 50 and the third outer surface 55. In a preferred embodiment, each surface 45, 50 and 55 is circular, with the light assembly 20 located between the first 45 and third 55 outer surfaces. However, in other embodiments, one, or all of the surfaces 45, 50 and 55 may be elliptical, square, rectangular or other shapes. That is, the IMEA 15 may be round (as illustrated), but it may also be elliptical, square, rectangular or other shapes.
As shown in FIG. 4, the difference in diameters, or circumferences between the first 45 and second 50 outer surfaces forms an outer lip 60 that extends around the entire outer surface of the IMEA 15. During installation of the IMEA 15 to the motorcycle exhaust pipe 10, the second outer surface 50 of the IMEA 15 is inserted into the motorcycle exhaust pipe 10 until the outer lip 60 contacts the motorcycle exhaust pipe 10. Fasteners are then inserted through apertures 65 that are located in the second outer surface 50, securing the IMEA 15 to the motorcycle exhaust pipe 10. Before the IMEA 15 is installed, the “stock” or original exhaust tip is removed.
Also shown in FIG. 4 is the first inner surface 70 having a first inner circumference and a second inner surface 75 having a second inner circumference larger than the first inner circumference. The difference in diameters, or circumferences between the first 70 and second 75 inner surfaces forms an inner lip, or shoulder 80 that extends around the entire inner surface of the IMEA 15. During installation of the IMEA 15 to the motorcycle exhaust pipe 10, the inner lip 80 contacts, and retains in position, the motorcycle exhaust pipe baffle 85, shown in FIG. 3. Without the inner lip 80 contacting, and retaining the exhaust pipe baffle 85, the baffle 85 would not be retained within the exhaust pipe 10.
Referring now to FIG. 2, the third outer surface 55 and a portion of the first inner surface 70 combine to form a cylinder that extends from the light assembly 20. The cylinder forms the distal end, or tip of the motorcycle exhaust 10.
Shown in FIG. 5, a removeable motorcycle exhaust tip 90 is illustrated. The removeable motorcycle exhaust tip 90 may be installed to personalize or customize the motorcycle 2, and extends beyond the length of the exhaust tip formed by the third outer surface 55 and a portion of the first inner surface 70, discussed above.
The exhaust tip 90 comprises a removeable cylinder 95 having a flange (not shown) located about a first end of the cylinder 95, the flange sized to abut the inner lip 80, with a distal portion of a second end of the cylinder 95 sized to extend beyond the light assembly 20. That is, the exhaust tip 90 is an insertable motorcycle exhaust tip element sized to be removeably insertable into the IMEA 15 so that a distal end portion of the motorcycle exhaust tip 90 extends beyond the light assembly 20.
The outer circumference, or surface of the exhaust tip 90 is sized so that it closely fits against the first inner surface 70. The outer diameter of the exhaust tip 90 does not need to remain constant, and can taper to a smaller diameter beyond where the cylinder 95 contacts the first inner surface 70. In addition, the portion of the cylinder 95 that extends beyond where the cylinder 95 contacts the first inner surface 70, and the light assembly 20 can be customized. For example, the cylinder 95 may have a plurality of apertures (not shown) or may include a plurality of scallops (not shown) arranged lengthwise on the surface of the cylinder 95. The tip of the cylinder 95 may include cut-outs, or may include “flame” shapes (not shown).
One advantage of the IMEA 15 is that it may replace the “stock” or original rear-facing running lights, brake lights and turn-signals, thereby eliminating the brake and turn signal lights that are usually mounted on stalks, or from other parts of the motorcycle 2. For motorcycle owners that wish to “customize” their motorcycles by “cleaning up” the motorcycle (i.e., eliminating components), the IMEA 15 eliminates the turn signals installed by the manufacturer.
Alternatively, for those motorcycle owners who wish to increase safety by increasing their “conspicuity” (i.e., their visibility), the additional lights provided by the IMEA 15 provide additional warning to motorists that the rider wishes to turn. In this case, the owner may wish to retain the original, manufacturer installed brake lights, running lights and turn signals, and add the additional lighting provided in the IMEA 15 (as shown in FIG. 1).
The IMEA 15 provides several functions and features. The IMEA 15 increases safety by increasing the “conspicuity” (i.e., the visibility) of the motorcycle by increasing the number of lights on the motorcycle, which provides additional warning and notice to motorists.
For example, the lights 30 contained in the IMEA 15 may function as either primary, or secondary turn-signal indicators (i.e., turn lights). That is, the motorcycle may not have any dedicated turn signal lights, and the lights 30 contained in the IMEA 15 function as the only, or primary turn signal indicators.
Alternatively, the lights 30 contained in the IMEA 15 may function as secondary turn-signal indicators. For example, a motorcycle rider, wishing to turn, activates a turn signal switch or other mechanism on the motorcycle. The turn signal switch activates the factory-installed (i.e., original motorcycle manufacturer) turn signal indicators on the motorcycle, which also activates the lights 30 in the IMEA 15 located in the appropriate side of the motorcycle.
The lights 30 on the IMEA 15 may be illuminated in a flashing, strobe, consecutive, sequential, or other type of illumination pattern.
It will be appreciated that the IMEA 15 may be installed on any existing type or model of motorcycle 2. In addition, the IMEA 15 may be installed on a “custom” motorcycle, which is a motorcycle that differs from a manufacturer-produced model. For example, a custom motorcycle may be a Harley-Davidson FXST Softail Standard that has had specific parts either added, removed or modified. Or, a custom motorcycle may be built from scratch, using no, or very few pre-manufactured parts, such as only the engine, transmission and tires. In addition, the IMEA 15 may be fitted on two-wheel motorcycles (with or without a side-car), and “trikes” (three-wheeled motorcycles).
It is to be noticed that the term “comprising”, used in the claims, should not be interpreted as being limitative to the means listed thereafter. Thus, the scope of the expression “a device comprising means A and B” should not be limited to devices consisting only of components A and B. It means that with respect to the present invention, the only relevant components of the device are A and B. Similarly, it is to be noticed that the term “coupled”, also used in the claims, should not be interpreted as being limitative to direct connections only.
Thus, it is seen an illuminateable motorcycle exhaust apparatus is provided. One skilled in the art will appreciate that the present invention can be practiced by other than the above-described embodiments, which are presented in this description for purposes of illustration and not of limitation. The specification and drawings are not intended to limit the exclusionary scope of this patent document. It is noted that various equivalents for the particular embodiments discussed in this description may practice the invention as well. That is, while the present invention has been described in conjunction with specific embodiments, it is evident that many alternatives, modifications, permutations and variations will become apparent to those of ordinary skill in the art in light of the foregoing description. Accordingly, it is intended that the present invention embrace all such alternatives, modifications and variations as fall within the scope of the appended claims. The fact that a product, process or method exhibits differences from one or more of the above-described exemplary embodiments does not mean that the product or process is outside the scope (literal scope and/or other legally-recognized scope) of the following claims.
