Patent Application

The present invention relates generally to motorcycle windscreens. More particularly, the present invention relates to a fairing-mounted windscreen of adjustable height.
For motorcycle riders, choosing the proper windshield height is of the utmost importance. Using a windshield of appropriate height is not only necessary for safety and protection reasons, but directly impacts riding comfort as well.
A windshield of taller height offers protection against wind, rain, cold, and road debris, but does not allow much air circulation for the rider, which is often desired for its cooling effect on hot days. A shorter windshield offers the rider increased air flow, which may be desirable on warm days, and a more stylish design, but does little to protect the rider against tough weather conditions like wind, rain, or cold.
Further, the rider's sightline relative to the windshield is also important when choosing a windshield height when a taller windshield is desired. Most riders like to have the top edge of the windshield sitting just below their line of vision when seated comfortably. This allows the rider to see over the windshield without straining, yet still be able to drop down and look through the windshield if conditions warrant. A related concern is the air flow over the windshield into the rider. Primarily, the concern is that the air will deflect off of the motorcycle's windshield and into the rider's head and catch the rider's head in turbulence. To counteract this, some riders prefer to have a slightly lower windshield so that the wind flowing off the windshield deflects off the rider's body rather than his head. Other riders prefer to have an even higher windshield such that the air flows off the windshield and over the rider's head. However, motorcycle riders vary in size and height. Thus, fitting windshields to all possible riders becomes impossible when the windshields come in a finite amount of heights.
Typically, motorcycle windshields have a fixed height. The height can vary among different windshields, but generally cannot be adjusted so that the height is variable on the same windshield. A motorcycle rider can therefore only have a tall windshield or a short windshield on his motorcycle at any one time. While this is generally not a problem for the rider who stays close to home (or close to a source of a differing height windshield), riders who travel far from home are at the mercy of changing weather or road conditions. For example, if a rider leaves his home on a very hot, calm day, he will likely do so with a short windshield that provides air flow to him. However, should it start to rain or gust when the rider is far from home, he will be in a precarious position with no windshield protection.
Carrying additional windshields such as in a saddle bag is impractical. A taller windshield would be bulky and difficult to fit in any motorcycle's side bag. Further, the risk of scratching the windshield would be high.
Further, while tinted windshields are desirable to some riders for style and/or function, their maximum allowable height is typically limited by regulation. Choosing a tinted windshield often means compromising with the various drawbacks associated with short windshields discussed herein.
Thus, there is a need for a motorcycle windshield that is adjustable to different heights. An easily adjustable windshield would provide the motorcycle rider the comfort and style of riding with a short windshield, yet afford him the flexibility of being able to easily and quickly switch to a taller-style windshield if conditions warrant, and vice versa. Further, a fully adjustable windshield solves the problem of handling the variation among rider heights.
An adjustable motorcycle windshield according to embodiments of the present application substantially meets the aforementioned needs of the industry. The windshield according to embodiments of the invention is adjustable to multiple heights.
In one embodiment, the windshield can be set at a fixed short height and easily adjusted to a fixed tall height, or vice versa. A windshield that is adjustable by the rider in this manner solves the problem of choosing between comfort and safety. In effect, a windshield of this embodiment allows the rider to have both, without the burden of carrying additional windshields. For example, a rider leaving his house on a hot day can do so with the windshield in the fixed short position. This allows for air circulation to the rider and is often desirable for its more stylish design. However, should the rider happen upon inclement weather during his ride, he can simply pull off the road, loosen a few fasteners, flip the windshield over, re-secure the fasteners, and continue his ride with the windshield in the fixed tall position. Adjusting the windshield to the fixed tall position allows the rider to continue his ride safely, as the new windshield height protects the rider against wind, rain, cold, and road debris. Similarly, should the rider leave his house on a cold, rainy day, he can do so with the windshield in the fixed tall position, knowing that he can later flip the windshield over to the fixed short position once he reaches hot weather.
In another embodiment, the windshield can be set at a tall height, a short height, and any height in between. A windshield that is adjustable to any height not only solves the problem of picking between comfort and safety, as described in the aforementioned embodiment, but also addresses the issue of fitting the windshield to individual rider size and height. While one rider may appropriately utilize the windshield's tallest height, that height may be inappropriate for a rider of slightly different height. For example, when the windshield is set at its tallest position, a slightly taller rider may experience turbulence from the wind flow off the windshield, as his head would sit above the windshield in prime turbulence position. Likewise, a slightly shorter rider utilizing the windshield at its tallest height may not suffer from the turbulence problem, but could potentially have his view obstructed by the edge of the windshield. A windshield of fully adjustable height solves these problems. The taller rider can adjust the height to one that is taller and appropriate for him such that his head is not caught in turbulence and he has a clear line of vision, and similarly, the shorter rider can adjust the height to one that is shorter and appropriate for his head position and line of vision. Further, as alluded to above, a windshield of this embodiment can easily adjust from a relative tall height (depending on the rider) that protects the rider from wind, rain, cold, and road debris to a relative short height, which allows for air flow to the rider.
The above summary of the invention is not intended to describe each illustrated embodiment or every implementation of the present invention. The figures and the detailed description that follow more particularly exemplify these embodiments.
The invention may be more completely understood in consideration of the following detailed description of various embodiments of the invention in connection with the accompanying drawings, in which:
While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
In the following detailed description of the various embodiments of the present invention, numerous specific details are set forth in order to provide a thorough understanding of various embodiments of the present invention. However, one skilled in the art will recognize that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as to not unnecessarily obscure aspects of the various embodiments of the present invention. The drawings, which are not necessarily to scale, depict illustrative embodiments and are not intended to limit the scope of the invention.
The adjustable motorcycle windscreen of the present invention provides a solution for motorcycle riders to quickly and easily adjust their windscreens to various heights. The invention can be more readily understood by reference to its application in
In one embodiment depicted in
In operation, a comparison of
In an optional embodiment not depicted, horizontal crossbar 16 is not needed for windshield 10. The tightening of fasteners 18 through apertures 20 and apertures 22 into nuts 24 adequately secures upper portion 12 to lower portion 14.
In another embodiment depicted in
Crossbar 56 contains apertures 60 in the same relative position as apertures 62 and nuts 64. Fasteners 58 are placed on both sides of windshield 50 and can secure adjustable windshield 50 in a fixed tall height through crossbar aperture 60, upper portion aperture 62, and into lower portion nut 64 along line 66. Further, lower portion 54 can be secured at any other height by securing crossbar 56 to lower portion 54 via fasteners 58 along line 66. Tightening fasteners 58 through apertures 60 of crossbar 56 and into nuts 64 of lower portion 54 creates force along the entire thee of crossbar 56 when it rests against upper portion 52. This force holds upper portion 52 securely in place.
hi operation upper portion 52 may be adjusted by loosening fasteners 58 from nuts 64. Once the pressure from crossbar 56 is adequately lessened, upper portion 52 is free to slide up or down. the rider can then position upper portion 52 at a desired position and retighten fasteners 58 through crossbar apertures 60 and into lower portion nuts 64, thus placing the requisite amount of force through crossbar 56 into upper portion 52 to hold it securely in place. Referring to
By way of example only, in one embodiment windshield 50 can be up to twelve inches in total height in its tallest position, which is attained by combining the five inches of lower portion 54 and the seven inches of upper portion 52, when upper portion 52 is positioned at its maximum height. In its shortest position, windshield 50 can be as short as seven inches in total height, which is attained by combining the five inches of lower portion 54 with the two inches of lower portion 54 when lower portion 54 is positioned at its minimum height. Thus, the overall height of windshield 50 is adjustable within a range from seven inches to twelve inches. These dimensions are merely for purposes of illustration and should not be considered limiting.
