BRIEF DESCRIPTION OF THE VARIOUS EMBODIMENTS OF THE INVENTION
Prior to proceeding to the more detailed description of the present invention, it should be noted that, for the sake of clarity and understanding, identical components which have identical functions have been identified with identical reference numerals throughout the several views illustrated in the drawing figures.
The present invention will be illustrated in use with a motorcycle 2 employing a fluid cooled engine 4 and best shown in FIG. 1. Such motorcycle 2 is presently manufactured for example by a Harley-Davidson of Milwaukee, Wis. under the VRSC family series including models known as VRSCX, VRSCAW V-Rod.RTM, VRSCR Street Rod.RTM, VRSCD Night Rod.RTM and VRSCDX Night Rod.RTM Special.
Reference is now made, to FIGS. 2-6, wherein there is shown a prior art radiator cover 10 for the motorcycle 2. The radiator cover 10 has a front end 12 which is positioned toward the front wheel 6. A pair of air intake apertures 14 and 15 are formed within the front end 12. The openings 14 and 15 have identical size and shape but are positioned in a mirror manner in relationship to a longitudinal centerline of the radiator cover 10. Each aperture 14, 15 is approximately 3 inches wide and approximately 13 inches long. As it is well known, the air intake apertures 14, 15 allow entry of a detrimental extraneous foreign material such as leaves, branches cigarettes remnants, rocks and the like present in an operating environment into the radiator cover 10 and, more particularly, enable accumulation of such detrimental extraneous foreign material on the front radiator surface (not shown).
In further reference to FIG. 2-6, therein is shown a pair of prior art bezel frames 20, 21 each positioned adjacently a respective one of the pair of air intake apertures 14, 15 and removably fastened to such radiator cover 10. The bezel frames 20 and 21 are identical except for basically a right hand and a left hand configuration. Accordingly, the following description will be concerned with the bezel frame 20, as those skilled in the art will readily understand that use of the present invention with the bezel frame 21 which is disposed adjacent its respective air intake aperture 15 is identical to the present invention used in combination with the bezel frame 20 other than the direction of bending or orientation of flanges of such bezel frame 20.
The prior art bezel frame 20 has an aperture 24 formed within a front end 22. The aperture 24 is generally equal in size and shape to the air intake aperture 14 of the radiator cover 10. Accordingly, the prior art bezel frame 20 performs only an ornamental function and does not prevent entry of a detrimental extraneous foreign material into the air intake aperture 14 and accumulation of such detrimental extraneous foreign material on the front surface (not shown) of the radiator (not shown).
In a particular reference to FIG. 6, the bezel frame 20 includes a generally thin lip 25 which surrounds the aperture 24 except for a portion thereof which is disposed adjacent fingers 27. The lip 25 is about 0.125 inches wide and forms a step with the rear surface of the front end 22 which has been determined to be about 0.020 inches.
The prior art bezel frame 20 has a plurality of elongated tubular members 26 which extend outwardly and generally perpendicular to the rear surface of the front end 22 and which are positioned along one edge of the aperture 24. A mounting bracket 28 is rigidly attached to the rear surface of the front end 22 adjacent an opposed edge of the aperture 24. The bracket 28 has a mounting aperture 29 whose axis is disposed generally perpendicularly to direction of the elongated tubular members 26.
To removably fasten the bezel frame 20 to the radiator cover 10, the later is adapted with a plurality of apertures 16 which are positioned in a lip 17 which is formed adjacent one edge of the air intake aperture 14 and which are aligned with the tubular members 26 of the bezel frame 20 and a complimentary mounting bracket 18 which is positioned adjacent an opposed edge of the air intake aperture 14 and has an aperture (not shown) which is aligned with the aperture 29 formed in the mounting bracket 28 of the bezel frame 20.
Now in reference to FIGS. 7-9, therein is illustrated an improvement for preventing entry of the detrimental extraneous foreign material into the radiator cover 10 through the air intake aperture 14 according to one embodiment of the invention.
Such improvement comprises a grille means, generally designated as 30, which includes a unitary elongated member 32 having each of a predetermined size and a predetermined shape. The elongated member 32 preferably has a paper-thin like peripheral edge 34, best shown in FIG. 8, which surrounds the surface portion 33 of the unitary member 32 except for a portion thereof provided with notches 35 to fit around fingers 27 of the bezel frame 20. A plurality of apertures 36 are formed in such surface portion 33.
In a particular reference to FIG. 9, the unitary member 32 is caged between such front end 12 of such cover 10 and the bezel frame 20. Accordingly, the paper-thin like peripheral edge 34 of the unitary member 32 abuts the inner surface of the lip 25 of the bezel frame 20 and has a thickness being equal to or less than 0.020 inches to enable alignment of the plurality of apertures 16 with the plurality of tubular members 26 and more particularly, enabling alignment of the aperture (not shown) formed within the mounting bracket 18 with the aperture 29 of the mounting bracket 28 of the bezel frame 20. Such alignment enables fastening of the bezel frame 20 to the front end 12 on the motorcycle engine that were manufactured prior to the present invention. It would be appreciated that plurality of apertures 36 enable air flow into the radiator cover 10 through the air intake aperture 14 but prevent entry of such detrimental extraneous foreign material into the radiator cover 10.
The thickness of the surface portion 33 of the elongated member 32 may be identical to the thickness of the peripheral edge 34, but, preferably, the thickness of the surface portion 33 is greater than the paper-thin like peripheral edge 34 to improve rigidity of the elongated member 32 during use in harsh applications, for example such as off-road driving. It has been found that a thickness of between about 0.030 inches and about 0.040 inches is sufficient to maintain desired rigidity.
To accommodate the size of the aperture 24 of the prior art bezel frame 20, the presently preferred length of the elongated member 32 is about 15.13 inches and the presently preferred width of its widest section disposed generally adjacent the bend line 38 is about 3.38 inches.
To accommodate the shape of the prior art bezel frame 20, the grille means 30 includes an angular bend 38 formed across a width of the elongated member 32 and dividing it into a pair of surface portions disposed at an angle to each other. The grille means 30 further includes a curvature 35 laterally formed within the elongated member 32.
The elongated member 32 is preferably manufactured from a metal such as aluminum and, more particularly, such as a perforated aluminum already incorporating round apertures 36 therein. Alternatively, expanded type aluminum may be used with apertures 36 being of a diamond shape, as best shown in FIG. 10. Alternative materials such as steel and plastic and their combination as well as alternative shapes of the apertures 36 may be employed in the instant invention.
It will be apparent to those skilled in the art that the grille means 30 may be simply and economically manufactured from the perforated or expanded material and may be easily installed without the use of additional fasteners or adhesives.
Now in a particular reference to FIGS. 10-11, therein is illustrated an improvement for preventing entry of the detrimental extraneous foreign material into the radiator cover 10 through the air intake aperture 14 according to another embodiment of the invention.
Such improvement comprises a grille means, generally designated as 50, which includes a member 52 having a generally thin surface portion 54 and a flange 56 which extends outwardly from the surface portion 54. The flange 56 is shaped to fit an exterior surface of at least one of such front end 12 and such bezel frame 20 being attached thereto. A fastening means 58 is provided for mounting the grille means 50 to such exterior surface in one of a semi-permanent and permanent manner. Such fastening means 58 may include one of an adhesive, a double-faced adhesive tape and a hook and loop fastener. A plurality of apertures 59 formed in the surface portion 54 enable air flow into the radiator cover 10 through the air intake aperture 14 and prevent entry of such detrimental extraneous foreign material into the radiator cover 10. Such grille means 50 may be simply and economically manufactured from a perforated or expanded material by a stamping process.
Now in a particular reference to FIG. 12, therein is illustrated an improvement for preventing entry of the detrimental extraneous foreign material into the radiator cover 10 through the air intake aperture 14 according to yet another embodiment of the invention.
Such improvement includes a bezel, generally designated as 60, which is constructed identical to the prior art bezel frame 20 except that the bezel 60 includes a generally thin surface portion 62 which is formed integral to the bezel 60 and which essentially closes the aperture 22 of the prior art bezel frame 20. A plurality of apertures 64 are formed in the generally thin surface portion 60 which enables air flow and prevents entry of such detrimental extraneous foreign material into such radiator cover 10.
According to a further embodiment of the invention, best shown in FIG. 13, the improvement includes a radiator cover 70 having a pair of generally thin surface portions 72 which are formed integral to the front end of the radiator cover 70. Essentially, each surface portion 72 closes its respective aperture 14 of the prior art radiator cover 10. A plurality of apertures 74 are formed in each generally thin surface portion 72 enabling air flow into the radiator cover 70 but which prevent entry of such detrimental extraneous foreign material thereinto A plurality of mounting apertures 76 formed in a lip 77 which is disposed adjacent one edge of the surface portion 72 and a mounting bracket 78 which is disposed adjacent an opposed edge of the surface portion 72 are provided for mounting the prior art bezel frame 20.
Thus, the present invention has been described in such full, clear, concise and exact terms as to enable any person skilled in the art to which it pertains to make and use the same. It will be understood that variations, modifications, equivalents and substitutions for components of the specifically described embodiments of the invention may be made by those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims.
