1. Field of the Invention
This invention relates to a novel aid for shielding a wheel center. More particularly, the present invention relates to expandable wheel shields that protect the centers, including the rim, spokes, hubcap and the like of wheels of varying diameters, from the over application of tire dressing and other chemicals.
2. Description of the Prior Art
The shielding and protection of automobile wheels is generally needed because during the detailing process of a car, the entire car is washed, including the rim and hubcaps, before the dressing is applied to the tires. Any dressing that gets on the rim and the hubcaps is not only a waste of product and but also highly inefficient as those wheels must now be cleaned a second time.
Heretofore, several types of shields and wheel protectors have been devised for just such protection and prevention. These prior art wheels covers generally utilize a circular disc with a radial gap, the sides of which are laid over each other and held in place by tabs, snaps, or other locking mechanisms, thereby giving it a conical shape and decreasing the diameter of the disc to fit the diameter of the tire rim. Another method employed by the prior art is generally that of a folding hand fan, having a plurality of circular-arc sectors overlapping each other and fanning about a central point. Adjusting this type of wheel guard is an involved and tedious process requiring the user to manually adjust each arc sector individually.
The following eight patents are relevant to the field of the present invention.
1. U.S. Pat. No. 4,196,692 issued to Marc. Q. Vanstrom on Apr. 8, 1980 for “Adjustable Paint Guard For Windows” (hereafter the “Vanstrom Patent”);
2. U.S. Pat. No. 4,792,191 issued to Frederick M. Farmer on Dec. 20, 1988 for “Automobile Wheel Protector” (hereafter the “Farmer Patent”);
3. U.S. Pat. No. D438,835 issued to Kurt A. Maschino on Mar. 13, 2001 for “Protective Wheel Mask For Spraying Vehicle Tires” (hereafter the “Maschino Design Patent”);
4. U.S. Pat. No. 6,412,878 issued to Henry O. Bell et al. on Jul. 2, 2002 for “Disposable Wheel Shield” (hereafter the “Bell Patent”);
5. U.S. Pat. No. 6,485,106 issued to Brett Lee Hermansen et al. on Nov. 26, 2002 for “Size Adjustable Wheel Rim Masks” (hereafter the “Hermansen Patent”);
6. U.S. Pat. No. 6,905,177 issued to Danny Murillo on Jun. 14, 2005 for “Rim Shield” (hereafter the “Murillo Patent”);
7. U.S. Pat. No. D537,401 issued to Neil Jones on Feb. 27, 2007 for “Wheel Shield” (hereafter the “Jones Design Patent”);
8. U.S. Pat. No. 7,448,694 issued to LaVern Bentley on Nov. 11, 2008 for “Rim and Hubcap Protection” (hereafter the “Bentley Patent”).
The Vanstrom Patent discloses an adjustable, rectangular, paint guard for windows, which contains four, identical, overlapping sections, each section having a generally triangular shape with the base of each triangle at the center of the device, and each apex of each triangle oriented at one of the four corners of the rectangle. The device pushes outwardly on each of the four triangle bases thereby expanding the area of the rectangle to cover a rectangular window so that it can be protected during the time when the seal around the outside is painted.
The Farmer Patent discloses a wheel guard of the adjustable cone type, discussed above, having interlocking slits at predetermined locations to cover the diameters of car rims, and further having five holes located near the radial point as a finger hold for the device. Additionally, the device is scored radially every 45° so that the device may be folded for storage.
The Maschino Patent is a design patent that is of the adjustable cone type, discussed above, including three-arced rows having a plurality of slits into one of three corresponding tabs interlocks, thereby adjusting the diameter of the device to fit the interior diameter of the wheel of a car, and also having several holes located near the radial center to provide the user with a finger hold for the device.
The Bell Patent discloses a wheel shield to cover the wheel rim, having a small tab as a handhold and having a plurality of concentric circles perforated close to the outside edge of the device. The Bell device is adjusted by reducing the circumference of the device by removing any of the perforated concentric circles that are larger than the tire rim that is to be protected.
The Hermansen Patent discloses a wheel guard of the adjustable cone type, discussed above, having a plurality of spaced apart snap bottoms and one mating snap top to adjust the diameter of the device, and holes near the conic apex to be used as a finger hold.
The Murillo Patent discloses a wheel guard of the hand fan type, having a plurality of arc sectors appending from a shaft, will all shafts pivoting from a single central point. Adjustment of Murillo device is tedious and time consuming in that it requires the user to manually adjust each shaft individually to create the desired diameter of coverage.
The Jones Patent is a design patent that appears to disclose a wheel shield of one piece that mimics the look and shape of an actual tire, and, because of the curvature of the device and the tabs extending backwardly, the device can sit over the entire wheel, thereby shielding not just the inner rim, but also the tire.
The Bentley Patent discloses a wheel shield of the hand fan type, having a plurality of circular arc sectors that pivot about a central point. A tab on the central point serves as the hand hold. Although it can fold up like a fan, the Bentley device does not teach the possibility of altering the diameter of its device.
Most of the prior art are disc shaped devices that deform into a conical section or are devices that are akin to folding hand fans. The prior art does not provide for a wheel shield that quickly and easily adjusts from one wheel rim diameter to another. The prior art does not provide for a wheel shield that adjusts its diameter of coverage without fussing with tabs, slits, snaps, or manual manipulation of each individual segment. The prior art does not provide for a wheel shield that is made of a plurality of segments that are not arc sectors and yet completely cover the interior diameters of automobile tires. The prior art does not provide for a wheel shield that is made of a plurality of segments capable of the effortless increase or decrease in its diameter of coverage.
The present invention is an adjustable and expandable shield for the rim and the hub of a wheel, to protect them and keep them clean during the detailing process for the tires. Without this shield, the rims and hub which have already been cleaned during the general cleaning of the car become dirty when tire dressing is applied to the tires and would therefore need to be cleaned a second time to remove the tire dressing that sprayed onto the rim and hub. This device covers the rim and hub so that when tire dressing is applied, the rim and hub are shielded from the spray and will not get dirty.
Another feature of the invention is that it is adjustable or expandable. For example, the inner diameter of tires for cars range from 15″ to 24″. The prior art is generally of a single diameter, which means that a car detailer would need at least one shield in every size to protect the range of sizes of wheels. The invention is a multi-pieced device that has, for purposes of being used as a tire shield, a minimum diameter of coverage of 15″. The invention can be of various proportions depending on the requirements of the user. It can expand to any diameter up to 24″ by pulling on the primary plate. Pulling on the primary plate affects the second plate, which has “fans” or “blades”. The blades are on the second plate, sandwiched between the second plate and the first plate. Also sandwiched between the two plates is a device that controllably moves all the blades simultaneously either outwardly or inwardly. Pulling/pushing on the handle on the primary plate activates this device, and all the blades are pushed outwardly or pulled inwardly, respectively, around the circumference of the two plates. The blades overlap each other so that there are no gaps and so that the newly expanded area is entirely closed and can thus protect larger wheels as effectively as the smaller 15″ wheel. The blades, when extruded outwardly to any degree, form a nearly perfect circle.
Another feature of the present invention is that it can expand and contract using only one hand and a simple flick of the wrist. Depending on the orientation of the blades in relation to the handle, a sharp flick of the wrist counter-clockwise will cause the blades of the present invention to fan outwardly and increase the diameter of coverage. Correspondingly, flicking the device clockwise will cause the blades to retract and thus reduce the area of coverage. The present invention may further be not limited to only opening when flicked in one direction and closed in the other. The blades of the present invention may be made sensitive to any rotational force and reverse their position in response thereto. Additionally, a user may become adept at the application of force such that the user knows how much force to apply to achieve the blades expanding out to a particular distance.
It can further be seen that the present invention has uses beyond that of shielding tire rims. The compact nature of the invention, the ease of use, and the ability for sudden expansion and retraction, makes the present invention ideal for other uses. One alternate use is for use by auxiliary members of a marching band, wherein the present invention can have blades in the school or team colors and as part of the show, a display of the combination of color and the expansion/retraction of the invention will create a very dynamic display. Another use is by cheerleaders, wherein the present invention can have blades in the school's or team's colors, or be colored in such a way that when a plurality of fans are grouped together they form a picture or word. Additionally, a second set of handles may be placed on the other side of the device, and by having different sides of the present invention with different colors for different effects and a handle on either side, it can be seen that one may go from using one side to the other side, quickly and easily, thus the changing effects may be done smoothly and quickly, thereby maximizing the effect of the blades. Another alternate use could be for sporting events, wherein the present invention is passed out to spectators to inspire, rally, cheer, heckle and the like, and further can contain advertising, wording, and various colors and combinations. Other practical uses include the present invention being used as a fan to alleviate the heat, or as an umbrella, which, in the retracted condition, can be carried in a brief case, tote bag or purse and taken out and expanded in the event of rain or need for shielding from the sun. The present invention can also be used as a flying disc for games or sports.
It is therefore an object of the present invention to provide an adjustable and expandable shield for the rim and the hub of a wheel, to protect them and keep them clean during the detailing process for the tires.
It is a further object of the present invention to provide a shield so that the rims and hub which have already been cleaned during the general cleaning of the car will not become dirty when tire dressing is applied to the tires and eliminate to reclean to rims and hub from the tire dressing that sprayed onto the rim and hub. This device covers the rim and hub so that when tire dressing is applied, the rim and hub are shielded from the spray and will not get dirty.
It is an additional object of the present invention to provide a shield which is adjustable or expandable. It is an object of the present invention to provide a shield which comprises a multi-piece device that has, for purposes of being used as a tire shield, a minimum diameter of coverage of 15″. The invention can be of various proportions depending on the requirements of the user. It can expand to any diameter up to 24″ by pulling on the primary plate. Pulling on the primary plate affects the second plate, which has “fans” or “blades”. The blades are on the second plate, sandwiched between the second plate and the first plate. Also sandwiched between the two plates is a device that controllably moves all the blades simultaneously either outwardly or inwardly. Pulling/pushing on the handle on the primary plate activates this device, and all the blades are pushed outwardly or pulled inwardly, respectively, around the circumference of the two plates.
It is also an object of the present invention to have the blades overlap each other so that there are no gaps and so that the newly expanded area is entirely closed and can thus protect larger wheels as effectively as the smaller 15″ wheel. The blades, when extruded outwardly to any degree, form a nearly perfect circle.
It is an additional object of the present invention to provide a shield where the blade can expand and contract using only one hand and a simple flick of the wrist. Depending on the orientation of the blades in relation to the handle, a sharp flick of the wrist counter-clockwise will cause the blades of the present invention to fan outwardly and increase the diameter of coverage. Correspondingly, flicking the device clockwise will cause the blades to retract and thus reduce the area of coverage. The present invention may further be not limited to only opening when flicked in one direction and closed in the other. The blades of the present invention may be made sensitive to any rotational force and reverse their position in response thereto. Additionally, a user may become adept at the application of force such that the user knows how much force to apply to achieve the blades expanding out to a particular distance.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.
Referring particularly to the drawings for the purpose of illustration only and not limitation, there is illustrated:
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
Referring now to
Also on the first exterior surface 22, there can be seen the upper assembly 63 of a plurality of threaded bolts or pegs 62. However on the reverse side 13, the lower assembly 64 (see
The portions of the blade assembly 60 which is readily seen in these views are two panels, first panel 67 and second panel 68. It is preferable that second exterior surface 24 and second panel 68 are the same article, and they are shown in this way in the figures of the present invention, however, they need not be the same article and may be two distinct items. These panels 67 and 68 house and protect the blades 70, provide a platform for blades 70 to extend and retract, and set the minimum diameter of coverage. First panel 67 and second panel 68 are preferably of the same diameter. As shown in
The blades 70 of the present invention shield 10 have a unique shape, as illustrated in
Now referring to
Each pivot hole 71 of each blade 70 has a corresponding peg 62, and resides on the lower assembly 64 of a threaded bolt or peg 62. The lower assembly 64 of the pegs 62 rises up through a third panel 69. Third panel 69 has a smaller diameter than those of first panel 67 and second panel 68. It can be seen that the pegs 62, pass through and affix first exterior surface 22, first panel 67, pivot hole 71 of blade 70, and third panel 69. The pegs 62 do not affix to second panel 68. The result is that the blades 70 are pivotably affixed in this manner only by their pivot holes 71 to third panel 69, first panel 67 and first exterior surface 22, as shown on
The blade 70 is also affixed to second exterior surface 24 or second panel 68 in the following manner. A group of three blades 70 are arranged so that, although their pivot holes 71 each have their own pegs to which they are pivotably affixed, the three blades 70 share and are slidably affixed to the same post 66. The three blades 70 are sandwiched together so that the blade 70 on the bottom of the three has the post 66 in its first slot 81, the middle blade 70 has the same post 66 in its second slot 82, and the top blade 70 has that same post in its third slot 83, as illustrated by following tracing line “d”. Thus, while every blade contains a first slot, 81, a second slot 82 and a third slot 83, only one of these three slots 81, 82, 83 is being used at a time. This helps with reduced costs, because any blade can replace any other blade regardless of its position in the blade assembly 60. Additionally,
Referring now to
The shaft 30 penetrates the center point of the first exterior surface 22, the first panel 67, the third panel 69, the second panel 68, and the second exterior surface 24. Second exterior surface 24 may be the same or a separate article from second panel 68. The shape of the back edge 76 of the blades 70 is shaped to provide the length necessary for each of the three slots 81, 82, 83 on the plane 74 of the blade and yet be able to fit around and not be impeded by the shaft 30. The place where first arc 77 and second arc 78 meet is the part of the back edge 76 of the blade 70 that curves around the shaft 30 when the blades 70 are in the fully retracted condition.
As mentioned above, each of the three slots 81, 82, 83 trace out a different path. This is because each slot 81, 82, and 83, is at a different distance from the pivot hole 71, thus the different paths for each slot is to maximize coverage and to have proper alignment of the blade edge 75 of the shield regardless of how much of the blades 70 have been extended. Additionally, even at full extension, it is preferred that none of the slots 81, 82, 83 are open, but instead are covered by the overlap of the other blades 70, thereby completing the protection of the inner rim and hubcap of a wheel.
The blades 70 are able to expand and retract in the following manner. The heads 80 of the curved appendages 72 are affixed to third panel 69 between the third panel 69 and the first panel 67, the slots 81, 82, 83 are affixed to the second exterior surface 24 or second panel 68. It can be seen that because part of the blade 70, the curved appendage 72, is attached to one surface, first panel 67, and another part of the blade, the plane 74 by one of its slots, 81, 82, or 83, is attached to a different surface, second exterior surface 24, rotating first panel 67 and/or second exterior surface 24, in a direction opposite to the other, will force the blades 70 to move. By way of example, with the shield fully retracted, keeping first panel 67 still and rotating second exterior surface 24 relative to first panel 67, the pegs 62 affixed to first panel 67 are not moving and the posts 66 affixed to second exterior surface 24 are moving. Thus, one part of the blade 67, the curved appendage 72, is staying in place, but another part of the blade 70, the plane 74, is attached to the second exterior surface 24 that is moving. Although the curved appendage 72 is staying in place, it is able to rotate about its respective peg 62 through the pivot hole 71 in the head 80 of the blade 70. Additionally, the blade 70 is attached to second exterior surface 24 by having a post 66 in one of its slots, 81, 82, or 83. Rotating the second exterior surface 24 relative to the first panel 67, means that the post 66 also is moving relative to first panel 67. The blade 70 is able to move with second exterior surface: the head 80 moves about its pivot hole 71 and the post 66 exerts force on the slot 81, 82, 83, in which it resides, causing the blade 70 to move in relation to the post 66. This makes the slot 81, 82, 83 move upwardly in relation to the post 66, causing the blade edge 75 to extend beyond the diameters of first panel 67 and second surface 24. The blade edge 75 will extend outwardly in relation to the amount of rotation of second surface 24 or the amount of torque experienced by the blade 70, to a maximum reached when the post 66 hits the end of the slot 81, 82, 83. The diameter of the protected area is infinitely adjustable up to the maximum length available, as set by the proportion of the blades 70 and the length of the respective slots 81, 82, 83. The length of the slot 81, 82, 83 is preferably set so that the maximum blade edge 75 is exposed yet the blades 70 maintain a circular perimeter when overlapped. For use as a tire shield, it is preferable that the largest diameter of extension is equal to that of the largest tire rim diameter, which at present is 24 inches. The present invention blade meets this by having a distance from pivot hole 71 center to nub 73 of approximately 29 centimeters.
Likewise movement or rotational force in the opposite direction will put force on the slots 81, 82, 83 of the blade 70, resulting in the slot 81, 82, 83 moving downwardly relative to the post 66. This has the effect of the blade 70 retracting and the diameter of coverage decreasing down to the minimum diameter as set by the post 66 being stopped by the other end of the slot 81, 82, 83 or being stopped by the nub 73 of one of the blades 70 within the group of three unable to retract as prevent by a different post 66 or both.
Thus it can be seen that as the user becomes adept at using the present invention shield 10, the user may learn to use the shield 10 with one hand and may learn to know how much torque is required to extract the blades 70 to particular distance. The present invention shield 10 easily can be adapted for cheerleading, parades, and the like. By having the blades 70 of a particular color or set of colors or by having the blades one color on one side and a different color on the other, a team's colors can be flashed for the crowd. Likewise, one side of the shield 10, with blades 70 fully extracted, may have a large letter printed on it. Therefore, a cheerleading squad may flash the team color with one side of the shield 10 and with the other side of the shield 10 spell out the team name or “CHARGE” or the like.
Of course the present invention is not intended to be restricted to any particular form or arrangement, or any specific embodiment, or any specific use, disclosed herein, since the same may be modified in various particulars or relations without departing from the spirit or scope of the claimed invention hereinabove shown and described of which the apparatus or method shown is intended only for illustration and disclosure of an operative embodiment and not to show all of the various forms or modifications in which this invention might be embodied or operated.
