CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to U.S. Provisional patent application to Bottjer entitled “WRITING DEVICE FOR SINGLE-DIGIT USE,” Ser. No. 61/877,412, filed Sep. 13, 2013, the disclosure of which is hereby incorporated entirely herein by reference. 
     
    
     BACKGROUND 
       [0002]    1. Technical Field 
         [0003]    The following relates generally to writing instruments, and in particular to a writing device that may be operated by single-digit use. 
         [0004]    2. State of the Art 
         [0005]    In many work environments, a writing instrument is integral to the completion of one&#39;s job. However, a problem arises when the job requires occasional, rather than continuous, use of the writing instrument. This is because, in most cases, both cannot be used at the same time—the complexities of the job require, at times, that the fingers are used without the burden of holding the writing instrument and, at other times, that the fingers manipulate the writing instrument to write. 
         [0006]    Such a situation introduces inefficiency into the job to be completed. For example, when a writing instrument must be set down and picked back up time and time again, significant time and effort may be wasted. When setting the writing instrument down, so that it does not roll away, one must turn away from the work being done and purposefully place the writing instrument on a level surface or other object. Moreover, every time the writing instrument is needed again, one must turn away from the task at hand, find the writing instrument to be used, and thereafter refocus on the task at hand. This transition between using the writing instrument, putting the writing instrument down to use one&#39;s fingers and hands without the writing instrument, and picking back up the writing instrument can be wasteful of one&#39;s time and inefficient in one&#39;s efforts. It is also cumbersome, repetitive, and even irritating in its monotony. 
         [0007]    It would therefore be very desirable and useful to have a new and improved writing device that can be deployed by a user without having to set it down or pick it back up. And, in addition thereto, the writing device should not impede one&#39;s efforts in performing the task at hand that requires occasional use of a writing instrument.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0037]    A detailed description of the hereinafter described embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures listed above. Although certain embodiments are shown and described in detail, it should be understood that various changes and modifications may be made without departing from the scope of the appended claims. The scope of the present disclosure will in no way be limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc., and are disclosed simply as an example of embodiments of the present disclosure. 
         [0038]    As a preface to the detailed description, it should be noted that, as used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents, unless the context clearly dictates otherwise. 
         [0039]    Referring to the drawings,  FIG. 1  depicts an embodiment of an adjustable writing device  10  in accordance with the present disclosure. The writing device  10  may further comprise various structural components that complement one another to provide the unique functionality and performance of the writing device  10 , the structure and function of which will be described in greater detail herein. For example, embodiments of the writing device  10  may comprise, among other components, a digit engaging member  20 , an instrument engaging member  30 , and a writing utensil  40 . 
         [0040]    Embodiments of the adjustable writing device  10  may comprise a digit engaging member  20 . The digit engaging member  20  may comprise an engagement body  22  that defines an engagement opening  24  that may be configured to be releasably and repeatedly coupled to and disengaged from a digit of a user. 
         [0041]    Embodiments of the engagement body  22  may be comprised of a rigid materials, such as metal, plastic, or composite materials of similar properties that may retain the shape of the engagement body  20  as it functionally engages the digit of the user. The engagement opening  24  may have a diameter that can be adjusted by altering or otherwise changing a length of the engagement body  22 . The diameter of the engagement opening  24  may be adjusted as needed to functionally engage the digit of the user. For larger diameter digits, the diameter of the engagement opening  24  may be enlarged accordingly. Similarly, for smaller diameter digits, the diameter of the engagement opening  24  may be reduced accordingly. The engagement opening  24  may be configured to be slid onto the digit of the user. In other words, the engagement opening  24  may functionally engage the digit of a user much like a ring might engage the digit of a user. The engagement opening  24  may provide a friction fit with the digit, so as to secure the device  10  onto the digit. In addition, the diameter of the engagement opening  24  may be adjusted after the device  10  is placed on the digit to securely snug the device  10  onto the digit and substantially prevent unwanted movement of the device  10 . The diameter of the engagement opening  24  may be altered by such means as are now known in the art or later developed, such as for example, but not limited thereto, by straps, buttons, hooks, hook and loop fasteners, belts, loops, zippers, elastic, adhesive, worm gears, clamps, etc. In addition, the diameter of the engagement opening  24  may be altered by adjusting the length of the engagement body  22  with respect to itself by such means as those described above, for example, but not limited thereto, by straps, buttons, hooks, hook and loop fasteners, belts, loops, zippers, elastic, adhesive, worm gears, clamps, etc. The engagement opening  24  may define an axis  26 . 
         [0042]    Embodiments of the adjustable writing device  10  may further comprise the engagement body  22  being made of flexible material, such as stretch material or elastic material. Under these conditions, the engagement body  22  may be stretched from its normal diameter and placed onto the digit of the user. Once over the digit, the flexible engagement body  22  may be released so as to return to its normal diameter and snugly engage the digit of the user and remain in place on the digit. 
         [0043]    Embodiments of the adjustable writing device  10  may further comprise the engagement body  22  having an axial width that is large enough to resist and substantially prevent the engagement body  22  from axially advancing along, radially spinning about, or pivoting on the digit of the user in response to forces acting on the device  10 . In other words, the engagement body  22  may have a width that provides sufficient stability, support, and friction to prevent undesired movement of the engagement body  22  on the digit. Moreover, the width of the engagement body  22  may yet be small enough to fit onto the proximal phalanges, the intermediate phalanges, and/or the distal phalanges of the user. In this way, the width of the engagement body  22  may allow the user to place the writing device  10  on one of the phalanges and thereafter use the normal articulation of the hand, and especially the fingers and thumb of the hand, despite the presence of the writing device  10  on the fingers and/or thumb. In other words, the width of the engagement body  22  may be configured to be less than the distance between neighboring joints of the digit on which the device  10  is placed so as to not interfere with the articulation of the joints between the phalanges. 
         [0044]    Embodiments of the adjustable writing device  10  may further comprise the engagement body  22  having slits, gaps, openings, slots and/or holes to allow the user&#39;s skin under the engagement body  22  to breathe with the ambient air. These slits, gaps, openings, slots and/or holes may be positioned haphazardly around the body  22  or may be placed intermittently on the body  22 . In this way, moisture from the user&#39;s skin can ventilate with the ambient air and thus evaporate without causing build-up of moisture and sweat that might otherwise cause the engagement body  22  to slip or displace on the user&#39;s digit. 
         [0045]    Embodiments of the adjustable writing device  10  may further comprise an instrument engaging member  30 . The instrument engaging member  30  may be configured to functionally engage a writing instrument  40 . Embodiments of the instrument engaging member  30  may be configured to be coupled to the digit engaging member  20 , such that the digit engaging member  20  may support the instrument engaging member  30  thereon and/or thereby. The instrument engaging member  30  may be configured to releasably and repeatedly couple to and disengage from the digit engaging member  20  by the coupling means  38 , so as to possibly be exchanged with other or additional instrument engaging members  30 . The coupling means  38  may be cooperating brackets, adhesive, hook and loop fastener, snaps, belts, slide on clips, ties, or other releasable coupling means known in the art. Alternatively, the instrument engaging member  30  may be configured to be fixedly coupled to the digit engaging member  20  by coupling means  38 . The coupling means  38  may further comprise welds, seals, permanent adhesive, or other permanent coupling mechanisms known in the art. Embodiments of the device  10  may further comprise the digit engaging member  20  and the instrument engaging member  30  being comprised of a single integral piece, wherein the digit engaging member  20  and the instrument engaging member  30  are a unitary body that yet permits the diameter of the digit engaging member  20  to be adjusted. 
         [0046]    As depicted clearly in  FIG. 4 , embodiments of the device  10  may further comprise the instrument engaging member  30  defining an axial sleeve or slot  36  running through the entire axial length of the instrument engaging member  30 , the slot  36  being configured to receive therein and there through the writing instrument  40 , such that a tip  42  of the writing instrument  40  may be inserted into the axial slot  36  and pushed through the axial slot  36  so as to extend out one side of the instrument engaging member  30 . A body  44  of the writing instrument  40  may extend out the other side of the instrument engaging member  30 . The body  44  may be configured to hold ink, pigments, dyes, liquids, pastes, or other marking material that may facilitate the tip  42  being able to leave marks, designs, text or images, on objects such as paper and the like. The axial slot  36  may be configured to functionally engage the writing instrument  40  by friction fit. The axial slot  36  may be configured to permit the writing instrument  40  to be removed from the axial slot  36  so as to permit the user to insert another or a different writing instrument  40  into the axial slot  36  to be engaged thereby. In this way, a set of writing instruments  40  may be utilized by the user of the writing device  10 , as desired. For example, the set of writing instruments  40  may include each instrument  40  in the set providing a different color, different font size (i.e, tip size), and/or different ink consistency. 
         [0047]    Embodiments of the adjustable writing device  10  may further comprise the instrument engaging member  30  being configured to position the writing instrument  40  substantially orthogonal to the axis  26  of the finger engaging member  20 , such that an axis  46  of the writing instrument  40  is substantially orthogonal to the axis  26  of the digit engaging member  20 . In this way, the writing instrument  40  may be positioned substantially orthogonally to the axis of the digit, and thus the axis of the phalange (or finger), upon which the device  10  is deployed by the user  60 , as depicted in  FIGS. 5 and 6 . As depicted in  FIG. 5 , the device  10  may be coupled to the phalange of the thumb so as to not interfere with the distal end of the thumb and the fingers combining to utilize a tool, such as a pen, pencil, or other writing instrument, not depicted. At any rate,  FIG. 5  demonstrates that the device  10  may not interfere with other normal operations of the thumb and fingers. As depicted in  FIG. 5 , the device  10  may be coupled to the phalange of the thumb so as to not prevent the thumb, fingers, and hand of the user  60  from resting in a comfortable position, such as a resting position with portions of the palm, thumb, and fingers resting on the surface. As depicted in  FIG. 6 , the device  10  may be coupled to the phalange of the thumb so as to not prevent the thumb, fingers, and hand of the user  60  from utilizing and competently operating components such as a mouse of a computer system, from typing on a keyboard of a computer system, or from other similar hand-required, or finger-manipulation tasks. 
         [0048]    Embodiments of the adjustable writing device  10  may further comprise the instrument engaging member  30  being configured to twist, spin, rotate, or otherwise pivot with respect to the digit engaging member  20  to reposition the writing instrument  40  such that the axial length of the writing instrument  40  is substantially parallel with the axis  26  of the finger engaging member  20 , or substantially parallel with the axial length of the digit on which the device  10  is configured. The instrument engaging member  30  may be configured to “click” into place in either the orthogonal or parallel configurations described above. In other words, once positioned at either the parallel or orthogonal configuration, the instrument engaging member  30  may be prevented from pivoting or releasing therefrom without user input, user operation, or user release. 
         [0049]    With particular reference now to  FIGS. 2-4 , embodiments of the device  10  may further comprise the writing utensil  40  being comprised of a writing tip  42  and a cartridge  44 . The cartridge  44  may be configured to house ink, pigments, dyes, liquids, pastes, or other marking material that may be utilized by the device  10  to write or otherwise mark on objects. The cartridge  44  may be configured to functionally communicate with the instrument engaging member  30  to pass the ink, pigments, dyes, liquids, pastes, or other marking material to the writing tip  42  that may be configured to receive the material from the cartridge and write or otherwise mark on objects and/or surfaces, as desired by the user. The writing tip  42  may be configured to functionally communicate with the opposing end of the instrument engaging member  30  to receive the ink, pigments, dyes, liquids, pastes, or other marking material from the cartridge  44  through the instrument engaging member  30 . 
         [0050]    Accordingly, embodiments of the adjustable writing device  10  may further comprise the instrument engaging member  30  further comprising a writing tip engaging member  32  and a cartridge engaging member  34 . The writing tip engaging member  32  may be configured to functionally engage the writing tip  42 . Likewise the cartridge engaging member  34  may be configured to functionally engage the cartridge  44 . In this way, the writing tip  42  may be releasably and repeatedly coupled to the instrument engaging member  30  via the writing tip engaging member  32 . Further, the cartridge  44  may be releasably and repeatedly coupled to the instrument engaging member  30  via the cartridge engaging member  34 . In this way, different cartridges  44  holding ink, pigments, dyes, liquids, pastes, or other marking material of various quantity, quality, color, consistency, or other characteristic may be coupled to or removed from the instrument engaging member  30 , as desired by the user. In like manner, different writing tips  42  of different size, font, type, or shape may be coupled to or removed from the instrument engaging member  30 , as desired by the user. As a result, the user may customize the adjustable writing device  10  according to the specific want or need. 
         [0051]    Embodiments of the adjustable writing device  10  may be worn on the thumb of the user, such that marks can be made on surfaces without the need for the user to pick up a writing utensil every time a mark must be made on the surface. Further, the user may move his/her hand in such a way as to mark text, letters, images, and/or designs on the same surface as needed. To do so, the user may desire to place the thumb against the palm of the hand, or other proximate surface of the hand, to hold the device  10  in place between the thumb and the hand while exerting force on the device  10  to cause the writing tip  42  to move in such a motion as to leave the desired leave marks, text, images, or designs. 
         [0052]    The components defining the above-described adjustable writing device  10  may be formed of any of many different types of materials or combinations thereof that can readily be formed into shaped objects provided that the components selected are consistent with the intended operation of a writing instrument of the type disclosed herein. For example, and not limited thereto, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass) carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal, Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination thereof, and/or other like materials; composites and/or other like materials; metals, such as zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, aluminum, any combination thereof, and/or other like materials; alloys, such as aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or other like materials; any other suitable material; and/or any combination thereof. 
         [0053]    Furthermore, the components defining the above-described adjustable writing device  10  may be purchased pre-manufactured or manufactured separately and then assembled together. However, any or all of the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, 3-D printing and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components. Other possible steps might include sand blasting, polishing, powder coating, zinc plating, anodizing, hard anodizing, and/or painting the components for example.
