Abstract
A mounting for a motorcycle fairing, which mounting permits both translational and angular orientation of the fairing relative to the motorcycle. A pair of flat elongate links at the lower forward portion of the fairing, each having a longitudinal slot, are spaced and joined pivotally at one end to the inside of the fairing. The links are crossed over each other and a bolt extends laterally through the opening formed at the intersection of the slots and is secured to the vehicle headlight on each side thereof. A pair of rods are secured at an upper portion of the fairing and extend downwardly and rearwardly therefrom with each end mating with a clamp on the motorcycle handlebars. The length and orientation of the rods between the clamps and the fairing is adjustable so as to accommodate fore-and-aft and angular movement of the fairing, which movement is made possible by the arrangement of the forward mounting links.

Description
Background of the Invention
This invention is concerned with a novel handlebar mounted motorcycle fairing which is adjustable rotationally and translationally on the motorcycle.
Summary of the Invention
In accordance with the present invention, the fairing has a mounting assembly which includes a means at the forward portion of the fairing, mating with the vehicle in such a manner that the fairing can be translated and rotated relative to the vehicle headlight. Toward the rear of the fairing, and adjacent the upper region thereof, is a brace which extends toward the handlebars and is engaged by a clamping assembly to stabilize the fairing and accommodate the fairing movement.
It is the principal object of the present invention to provide a versatile fairing mounting assembly that permits rotational movement as well as fore-and-aft and/or vertical adjustment of the fairing relative to the motorcycle so that the fairing might be oriented as desired. In a preferred form of the invention, at least two flat links, each with an elongate slot, join the fairing with the vehicle headlight. The links are pivotally secured at spaced positions on vertically disposed longitudinal flanges at the inside of the fairing. Preferably, a flange is provided on each side of the headlight, with each flange mounting a pair of links. The links are crossed over each other to intersect the slots and a bolt extended laterally through the point of intersection of the slots and into the tapped sidewall of the headlight. By tightening the bolts into the headlight, the fairing is fixed in the desired position.
The brace has a pair of spaced rods extending downwardly and rearwardly towards the clamping assembly. A clamp on each side of the handlebars has a substantially laterally extending lug with a transverse bore to receive the rods. The lug is rotatable to align the bore with the rod which it receives and is anchored in any desired position.
It is another object of the present invention to provide a fairing mounting that can be used on motorcycles having varying physical configurations. The clamping assembly can be moved along and anchored at any position on the handlebars. The fairing may be mounted on any motorcycle having handlebars and a headlight or like structure to which the forward mount can attach.

Detailed Description of the Drawings
Referring initially to FIGS. 1-3, a motorcycle fairing is illustrated having a fiberglass body 10 and a windshield 12 secured appropriately to an upstanding ledge 14 formed at the upper region of the body 10. The body 10 has a substantially rounded outer surface defining a cup-shaped inner region 16 which is situated about the handlebars 17. A U-shaped cutout 18 in the lower region of the fairing accommodates a circular headlight 20 mounted at the front of the motorcycle (not shown), which cutout 18 is preferably made large enough so as not to limit adjusting movement of the fairing, as hereafter discussed, and to accommodate headlights of different diameter.
At the edges of the cutout 18, and on opposite sides of the headlight 20, are a pair of vertically projecting flanges 22, formed integrally with the body 10. A pair of mounting links 24,26 are secured adjacent their lower end, as by bolting, at longitudinally spaced positions along each flange 22. Each link 24,26 is of a flat, elongate construction with a longitudinal slot 28 extending substantially along its length. The links 24,26 are crossed over each other and a bolt 30 extended laterally through the point of coincidence of the slots and into a tapped bore 32 in the sidewall of the light 20. The bolts 30 extending within the sidewall on opposite sides of the light 20 are aligned in a common horizontal axis about which the fairing is rotatable. The crossed links on each side of the headlight, being adjustable relative to each other, and to the headlight, accommodate rotational movement of the fairing about the bolts 30 as well as accommodating movement of the fairing both fore and aft and vertically with respect to the motorcycle. With the fairing in the desired position, the bolts in the headlight and flanges 22 are tightened to fix the fairing position. The triangular arrangement of the bolts assures that the fairing is anchored securely against movement in all directions.
At the upper region, and towards the rear of the fairing, is a flat, downwardly facing ledge 34 to which is secured a U-shaped bracing member 36 which extends downwardly and rearwardly from the ledge 34 to engage a pair of clamps 38 mated with the handlebars 17. Each clamp 38, as seen in FIGS. 4 and 5, comprises first and second body halves 40 and 42, respectively, with each of the halves defining a curved region 44 at their midportion, which approximates the curvature of the handlebars and is designed to fit closely thereabout. At the top edge of the first body half 40 is a curved longitudinal groove 46 and an aligned protruding ridge 48 immediately inward therefrom. The upper portion of the second body half 42 has a correspondingly configured, depending ridge 50 and adjacent groove 52 to cooperatively receive, respectively, the groove 46 and ridge 48 of the first half.
With the first half 40 positioned on the outside of the handlebar 17, the second half is mated thereto by first introducing the ridge 50 on the second half to the groove 46 in the first half with the bottom of the second half disposed away from the first half. With the upper portion of the first and second halves mated, the lower portion of the second half is rotated outwardly to seat the curved region 44 of the second half against the handlebars 17.
As can be seen in FIG. 4, flat wall portions 54,56, respectively formed at the bottom of the first and second body halves, do not closely abut. This particular arrangement permits the clamp 38 to fit about handlebars of varying diameters. Further, this permits a modicum of flexing at the lower portion of the body halves, such that the corners 58 formed at the intersection of the walls 54,56 and the curved portion 44 of each body half will be drawn inwardly towards the handlebars 17 to more positively grasp the same when the body halves are secured.
The body halves are secured to each other by a laterally extending bolt 60, having a lock washer 62 fit within a circular recess 64 in the second body half 42. A cylindrical sleeve 66 is fit in an aligned recess in the first body half 40, which receives and is secured with the bolt 60. As the handlebars 17 are of a generally uniform thickness, the clamping assembly may be fixed at any position therealong.
The base 70 of the U-shaped brace 36 is held against the downwardly facing ledge 34 by a clamp plate 72. As can be seen most clearly in FIG. 3, the ledge 34 is stepped to define a first face 76 and a ledge 78 displaced upwardly and rearwardly therefrom, such that the ledges cooperatively define a rearwardly opening, laterally extending corner 80. The plate 72 has a main, rectangular portion 82 bolted to the first face 76 and an upwardly offset edge 84 curved to the configuration of the brace 36 and being so designed to capture the base 70 of the brace 36 within the corner in a manner that the brace 36 is free to pivot about the lateral base 70.
The brace 36 defines rod-like legs 86, which each extend through a bore 88 in an expanded head 90 on the nut 68 of the handlebar clamps. With the bolts in the links 24,26 loosened, the fairing can be oriented as desired. The bolt 60 on the clamp is likewise loosened that the clamp might be positioned and that the head 90 might be oriented to align with the legs 86 of the brace 36 in whatever attitude they might take.
In FIG. 3 are shown alternative positions for the fairing. The fairing can be pivoted forwardly as much as is allowed by the legs 86 of the brace 36. The extremeties of the legs 86 have an enlarged head 92 which abuts the head 90 of the nut 68 to keep the brace from pulling away from the clamp. The top of the fairing is free to pivot rearwardly, as shown in phantom, as far as is permitted before the inside wall of the fairing abuts the handlebars 17. Fore-and-aft and vertical movement is restricted by the triangular linkage formed by the bolts joining the mounting links 24,26 with the flange and headlight, with the brace 36 being free to pivot below the clamps into the central offset region 94 of the handlebars.
The above description was made for purposes of clarifying the above invention, with no unnecessary limitations to be derived therefrom.
