Abstract
The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers.
Description




TECHNICAL FIELD




This invention relates to one color identification of tools in several embodiments. In a preferred embodiment, the invention relates to the combination of color contrasting metal and large, more easily and quickly identifiable numbers.




BACKGROUND ART




Historically, the usual manner of marking tools consists of imprinting identifying characters on the surface of the tool or stamping heavy imprintation of the identifying markings into the surface. This provides a permanent marking for permanent identification. Even more historically, however, the fractional numbers are difficult to read and eventually become covered with dirt and grease. The same problem arises with other wrenches as well. Some open end wrenches are marked only on one side making it necessary for a user to flip the wrench over to find the size markings or to turn the wrench around in such a manner that will bring the markings to a proper upright position so that the markings are readily legible.




One proposed solution cuts a color coded series of grooves around the tool. The grooves extend completely around the circumference of the tool. The grooves are cut deep in the surface of the tool and the color material is set deep within the groves. While this improves the problem somewhat, the numbers are still too small to read and weaken the tool. Also, the user must memorize several combinations of colors and placement spacing of the grooves to determine size. Further, the color codings and the deep grooves still collect dirt and grease.




DISCLOSURE OF INVENTION




This invention relates to one color identification of tools. Contrasting color and quickly identifiable numbers make for instant identification of the color coded tools. In one embodiment, color impregnates the metal or plating during the manufacturing process. The key of this coloring is to identify the tool quickly by coloring an area of the tool. Generally, a substantial or large portion of the tool is colored. Substantial or large is defined by the appliques, bands and sleeves in the FIGS. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers,

14


in contrasting color. Insert


12


is attached with epoxy or other type of structural adhesive. Insert


12


preferably is set into raised collar area or recessed area


16


that is created when tool is manufactured to protect it from wear and abrasion. Metric differentiation is determined by contrasting color around perimeter of insert


12


or similar type of identification.





FIG. 2

shows another OEM application. This is one color instant identification of color coded tools. Color coded band


18


is made of plastic, vinyl, urethane, rubber, nylon, or other material, Large raised or recessed numeric designations


20


are in contrasting color. Band


18


is applied using a type of adhesive or is molded into place. Band


18


fits into raised collar area or recessed area


22


that is created when the tool is manufactured to protect it from wear and abrasion. Metric differentiation is determined by contrasting color strips at each end of color band


18


or similar type of identification.





FIG. 3

shows still another OEM application for one color instant identification of color coded tools, This is the same concept as

FIGS. 1 and 2

without utilizing an insert or band of a different material. I still use the large raised or recessed numeric designations in contrasting color. Color coding


24


is provided by paint, dye, enameling or similar process inside recessed area


16


or


22


. Color coding


24


may also be established by dying all or part of the tool or may also be established by tinting during the plating process.





FIG. 4

shows an OEM application of this invention to the socket of a socket wrench. Illustrated is socket


26

preferably is colored during the manufacturing process of the socket. In another embodiment, the colored surface


30


may be a band that covers essentially all of the outer surface of socket


26


.





FIG. 5

shows after market applications. Color coded applique


32


of plastic vinyl, urethane, rubber and nylon or other resilient material with raised collar


34


around the perimeter are used to protect against wear and abrasion. Large raised or recessed numeric designations


36


in contrasting color also are used. Applique


32


also can be applied to surface of tool


10


or as banding


38


around the tool

or at each end


44


of banding


38


.





FIG. 6

shows OEM and after market color coded tool holders and organizers


46


. Tool holder and organizer


46


can be color coded with large numeric designations to correspond with tool


10


for ease in finding and replacing the tools. Color coding and numeric designation can be accomplished during manufacturing or applied as a type of applique


48


, sticker or other means for after market.





FIG. 7

shows a colored coded crescent wrench


50


according to this invention. Crescent wrench


50


comprises handle


52


having fixed jaw


54


and movable jaw


56


affixed to one end of the handle, Handle


52


also includes recessed hole


58


adjacent to movable jaw


56


. Recessed hole


58


houses a threaded cylindrical control member


60


engaging movable law


56


.




In a preferred embodiment, window


62


may include a color indicator means with numerical size designations such as ½ inch or ¼ inch or both color and numbers. For example, window


62


may house a multicolored or numbered shank or shaft


64


indicating the distance between jaws


54


and


56


. Shaft


64


preferably is attached to or a part of jaw


56


. Shaft


64


is colored or numbered to indicate the distance between jaws


54


and


56


. Shaft


64


engages threaded member


60


,




In still another embodiment, window


62


shows surface


64


of movable jaw


56


. Surface


64


then shows a color or numeral to indicate a distance between jaws


54


and


56


.





FIG. 8

is one color instant identification of nuts and bolts


70


. Nuts and bolts


70


can be color coded to correspond to their size, as well as correspond to color coded tools


10


. Nuts and bolts


70


can have one color designation indicating their size and a colored recessed groove corresponding to the appropriate size tool


10


. English bolts and nuts would have a corresponding colored grove


72


cut horizontally around the perimeter of bolt or nut head


74


. Metric bolts and nuts would have corresponding colored grooves


76


cut vertically at each of the six exposed faces of the nut or bolt head


78


.




The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. Preferably, in another preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers. Color coding the threaded portion of a crescent wrench is especially useful as these wrenches have no numerical markings.




In addition to these embodiments, persons skilled in the art can see that numerous modifications and changes may be made to the above invention without departing from the intended spirit and scope thereof.
