When referring to a wide or wider diameter this is used to specify that a particular diameter is wider than a narrow or narrower diameter, without regard for specific dimensions, other than to the extent they compare to each other.

[0039] As used herein, the term connected means two or more pieces connected through known means or it can mean integrated into as a singular piece.

[0040] As used herein, all singular terms refer to both singular and plural values. That is, a or an or the all mean one or more. The term or as used herein means any one or more of the alternatives, including all of the alternatives.

[0041] Throughout the present disclosure, when described in sequential words (for example, using then or next), such description is not limiting to the described steps in the particular order set forth, but also includes embodiments wherein the steps are presented in any order. Throughout the present disclosure, the use of the word user not limited to a particular person or persons, but can indicate actions performed by a machine, computer, a robot, or artificial intelligence (A.I.)

[0042] Various embodiments herein refer to an ink device. As used herein, ink device can refer to any unit made up of multiple parts, for example, a bundle of ink cartridges or styluses held together (that can, in various embodiments, be configured together or otherwise associated generally as a bundle, but are not necessarily physically connected to each other). In certain embodiments, a device herein can comprise a plurality of ink cartridges disposed within a barrel of a writing instrument, and essentially fitted together by their nibs' being inserted into one or more holes in a tip of the writing instrument, as will be discussed in greater detail herein.

Barrel and Tip

[0043] In certain embodiments, a writing instrument herein comprises a barrel, which is essentially a hollow tube that can encase one or more cartridges or styluses, and around which a user's hand can fit to use the writing instrument. For example, as shown in FIG. 1, in certain embodiments, a writing instrument 1 comprises a barrel 2 having a proximal end ending in a tip 3, and an opposite distal end. As used herein, tip refers to the portion of the writing instrument in which the one or more nibs or soft points are at least partially housed and which sits close to the substrate when the writing instrument is in use by the user. In the embodiments shown in, for example, FIG. 1 and FIG. 8, the tip is frusto-conical, although the tips described herein are not so limited. For example, as shown in FIG. 5 through FIG. 7 and FIG. 9 through FIG. 11, in certain embodiments, the tip is substantially triangular, or substantially trapezoidal. Further, as shown in FIG. 8 through FIG. 11, in certain embodiments, a tip herein can be translucent or transparent, such that a user can see the outline or details of the various nibs within the writing instrument, for desirable visual effect.

[0044] In various embodiments, the tip can be integral with the barrel, or can be a separate element that is connected to the barrel, as can be assembled during manufacture of the writing instrumentfor example, snapped on, glued on or screwed on. A tip of a stylus can be integral with In various embodiments, for example as shown in FIG. 1 and FIG. 4, a tip 3 herein has a diameter 4 that decreases from where it contacts the proximal end of the barrel 2, to the tip end 9, the point where a nib 5 protrudes. In certain embodiments, the tip 3 is frusto-conical, the diameter of which decreases (tapers) as it extends toward the tip end 9, which is the farthest point on the proximal end of the tip 3. In other embodiments, for example as shown in FIG. 5 through FIG. 7 and FIG. 9 through FIG. 11, the tip 3 has a wide enough diameter at the tip end 9 (its point closest to the writing substrate), such that it can accommodate an angling of the multiple pen or stylus nibs or soft points when a writer uses the writing instrument to write on a substrate, such as the horizontal surface of a piece of paper on a desk; thus, when the writer holds the writing instrument in the typical writing position, two or more of the multiple nibs 5 can all touch the substrate at substantially the same pressure, or at substantially different pressure (depending on the writing effect desired by the user). In such embodiments, using such a writing instrument can be ergonomically comfortable for the user.

[0045] In certain embodiments, as shown, for example, in FIG. 2 and FIG. 3 a tip 3 herein comprises, at its tip end 9, one or more holes 6 through which a nib 5 can be inserted, such that at least a portion of the nib 5 protrudes from the narrowest part of the tip 3 to touch the writing substrate when used to write. A tip end can be, at its simplest, one hole (such as would be the case with a basic ball point pen that has only one ink cartridge dispensing one color of ink); or multiple holes to accommodate multiple nibs. Thus, in various embodiments of the current technology, the tip end 9 can contain multiple holes, such that multiple nibs 5 can be inserted and maintain a desirable separation therebetween. For example, as shown in FIG. 2 through FIG. 4, in certain embodiments, the tip end 9 is at least partially solid, with holes 6 disposed along the solid portion, such that the multiple nibs 5 can protrude through the holes. In other embodiments, the tip end includes an opening large enough to accommodate multiple nibs at once, which can lie adjacent to each other in a bundle with no solid portion separating them.

[0046] In some embodiments, for example, as shown in FIG. 1 through FIG. 4, the nibs are ball point pen nibs 5, so a ball 7 is held within a hole 6, with the remainder of the cartridge 8 extending upward through the length of the barrel 2.

Nibs

[0047] The technology herein is not limited to nibs having a ball, such as with a ball point pen. As shown in, for example, FIG. 5 through FIG. 7 and FIG. 9 through FIG. 11, in certain embodiments, the one or more nibs in an ink device or writing instrument herein, that protrude through the hole in the tip end, can be a soft point such as a felt tip or marker or brush, a hard point or sharp point such as a fountain pen tip or stylus tip, dip pen tip, or quill tip, or any other material that is sufficient to transfer a flow of ink from the cartridge onto the substrate, or in the case of a stylus, sufficient to create a signal on a touch sensitive surface.

[0048] As shown in the embodiments in FIG. 5 through FIG. 7, in certain embodiments a substantially triangular or substantially trapezoidal tip 3, can have two or more ink cartridges 8 comprising a proximal end with a nib 5 and a distal portion 10, the proximal end disposed within the tip 3, and configured to contemporaneously transfer ink from the two or more ink cartridges to a substrate through the nib, and one or more (or each of) the ink cartridges having a different physical characteristic from the other ink cartridges.

[0049] As used herein, contemporaneously means in the same period of time, but not necessarily exactly simultaneously. Specifically, if a user uses a writing instrument herein by drawing the writing instrument along a substrate such as a piece of paper, if ink or signal flows from two or more nibs at any time during the stroke, this qualifies as contemporaneously transferring the ink or creating a signal from the different nibs to/on the substrate.

[0050] In certain embodiments in the case of a stylus, one or more ends 12 of stylus 8 is configured to create a signal on a signal receiving substrate. In other embodiments, an end 12 of stylus 8 further comprises one or more nibs 5 that are connected to, or integrated with, an end 12 of one or more styluses 8, for example, at the proximal end of stylus 8. In certain embodiments, the one or more ends 12, or the one or more nibs 5, are configured to contemporaneously create a signal from the stylus 8 to a signal-receiving substrate when one or more ends 12 or nibs 5 contemporaneously contact the substate. For example, as shown in FIGS. 8 and 12-14, in certain embodiments, a proximal end of each of the one or more styluses 8 of the writing instrument comprises nib 5, wherein each nib 5 contemporaneously contacts a substrate. In other exemplary embodiments, as shown in FIG. 13 and FIG. 14, nibs 5 are connected to, or integrated with, an end 12 of each of the one or more styluses 8 of the writing instrument. In other exemplary embodiments, as shown in FIG. 15, ends 12 contemporaneously contact a substrate.

[0051] In certain embodiments, one or more ends of stylus 8 is bifurcated, having more than one end 12, for example, as shown in FIGS. 13-14. In embodiments, one or more nibs 5 are connected to, or integrated with, one or more ends 12 of stylus 8 and can be configured to contemporaneously create a signal on a signal-receiving substrate. In another exemplary embodiment, two or more ends of stylus 8 comprise one or more nibs 5 at both a proximal end and opposite distal end of stylus 8. In such embodiments, depending on the end of the writing instrument chosen by the user to contact a substrate, nibs 5 of the one of the two or more ends of stylus 8 chosen by the user are configured to contemporaneously create a signal on a signal-receiving substrate.

[0052] In certain embodiments, for example as shown in FIGS. 5, one or more of the nibs 5 at the proximal ends of the ink cartridges or stylus 8 are at a substantially perpendicular angle relative to the distal portions 10 of the ink cartridges or stylus 8.

[0053] In various embodiments, the nibs 5 are configured such that they can be moved around relatively easilythat is, the order and orientation of the colors can be switched as desired by the usereither by using ordinary manual force to remove them from the holes 6 and reconfigure them and then insert them into different holes; or by manual depression of a latch or lever that switches the configuration of the nibs; or merely by shifting them around (in the embodiments that do not include a flat surface with multiple holes but rather just a single hole through which all of the nibs protrude or extend to contact the substrate). In other embodiments, the tip comprises a hole corresponding to each of the nibs, through which each individual nib extends to contact the substrate.

[0054] In other embodiments, the nibs are substantially permanently fixed into holes as determined during manufacture of the writing instrument or ink device, and cannot easily be altered by the user; or in the embodiments that do not include a flat surface with multiple holes, the nibs are held together in some other way that makes it difficult to shift their position through ordinary manual force (e.g., by mechanically binding the plurality of nibs together, either near the proximal end of the writing instrument, or farther away toward the distal end; or by configuring them inside the barrel in a tight configuration that does not allow for much movement). As used herein, ordinary manual force means customary and typical force that can be exerted by an adult or child with just the use of hands, and with no external assistance.

[0055] In certain embodiments of an ink device or a writing instrument herein, each nib is connected to the proximal end of an ink cartridge or stylus 8, wherein the ink device or stylus is configured such that, when placed within the barrel of the writing instrument, the plurality of nibs extend through the proximal end of the barrel and transfer the ink from the cartridges, or in the case of a stylus, create the signal from the stylus, to a substrate contemporaneously, providing a discernible effect of two or more physical or visual characteristics.

[0056] In certain embodiments herein, an ink device or writing instrument herein can comprise nibs of different sizes, to provide inks or signals of different effect. In certain embodiments, the ink that is transferred to the substrate from two or more different nibs provides a discernible effect of two or more characteristics. As used herein, characteristics mean any features that are distinguishably discernible by a user. These can include physical characteristics. As used herein, physical characteristics means characteristics that are discernible by a user through the eye, ear, mouth, or touchfor example, color, brightness, fluorescence, reflectivity, smell, smoothness or roughness, viscosity, erasability, or permanence. Thus, in some exemplary embodiments, different cartridges can provide inks with different visual characteristics such as different appearances (e.g., different colors, brighter versus muted colors, glitter, thickness of line); or different olfactory characteristics such as different smells; or different tactile characteristics such as viscosity of ink; or any different characteristics such as erasable ink versus permanent ink or the like.

[0057] In other exemplary embodiments, two or more different nibs 5 (or ends 12, as shown, for example in FIG. 15) of one or more electronic styluses 8 provides a discernible effect or function. In some exemplary embodiments comprising a plurality of nibs 5 or ends 12, each of the nibs 5 or ends 12 is capable of being independently programmed by means of software provided on a signal-receiving substrate to produce different visual characteristics on the signal-receiving substrate (e.g., colors, thickness, type of line such as solid, dashed or dotted lines, line texture) or perform a different function (e.g., writing tool, eraser tool, selection tool, zooming in/out, copy/paste). In certain embodiments, each of the two or more nibs 5 or ends 12 can be configured to create identical signals, such that each behaves the same way when interacting with the substrate, such as, for example, writing in the same color and thickness. In other embodiments, each of the two or more styluses can be configured to create different signals resulting in different characteristics providing a discernable effect.

[0058] Any feature that can discern at least two of the inks or signals from each other can be desirable for a user. In certain embodiments the discernable effect can be a spatial separation and the physical characteristics transferred to the substrate from the nibs can be the space between the ink or signals, created by the spatial relationship of the nibs.

Nib Angle

[0059] As can be seen, for example, in FIG. 1 and FIG. 2, in certain embodiments, the portion of the nib 5 protruding from the tip 3 at the tip end 9, is substantially perpendicular to the surface of the writing substrate. In such embodiments, the user can hold the writing instrument in a substantially perpendicular manner, in order to ensure that all of the nibs (the balls, in the case of a ball point pen) touch the surface adequately, thereby maintaining a desirable visual effect when the ink touches the substrate, in that all of the different colors or effects of the different nibs are shown. This can be helpful in the case of a substrate that is not a flat or substantially horizontal surfacefor example, a wall or ceiling or the like. This can also be helpful in an embodiment in which a writing instrument is being held and used by a mechanical apparatus, such as a robot arm.

[0060] In other embodiments, a proximal end of one or more nibs is angled such that, when placed within the barrel (e.g., within the tip) of the writing instrument, the plane formed by the proximal ends of the nibs is substantially parallel to the surface of a substrate when the writing instrument is held at a particular angle relative to the surface of the substrate. This can be seen, for example, in FIG. 5 and FIG. 6, and FIG. 13. This can make it easier for a user to use the writing instrument to write on a flat or substantially horizontal surface. In various embodiments, this angle can be 30 to 150 degrees, 50 to 120 degrees, or 65 to 115 degrees, relative to the surface of the substrate.

[0061] In various embodiments, the tip itself can include an axial opening that is angledthat is, one or more of a plurality of nibs in an ink device or writing instrument herein comprises an axial opening that is angled, such that the axial opening is substantially parallel to the surface of a substrate when the writing instrument is held at an angle. As can be seen from FIG. 4 through FIG. 6, whether or not the nibs are also angled, the tip 3 need not be conically shaped, but rather, can be angled in a manner that provides for ease of use by the user. In certain embodiments, one or more of the nibs comprises an axial opening in which a ball is held in a manner such that the ball rotates when moved against a substrate, thereby transferring ink to the substrate.

[0062] In other embodiments, the tip itself is angled, i.e., the tip end can be angled, to facilitate ease of use. In various embodiments, one or more or all of the tip or any of the nibs may or may not be angled. For example, in certain embodiments, it may not be necessary to angle any of the nibs, but merely to configure one or more of them in at different lengths within the barrel, so that an array of nibs can overall create a flat plane where the individual nibs are still substantially straight along their lengths, for example, as seen in FIG. 6 and FIG. 10.

[0063] In other embodiments, an end 12 of stylus 8 is angled, i.e., the stylus end itself can be angled, to facilitate ease of use. In various embodiments, one or more or all of the ends 12 or any of the nibs 5 may or may not be angled. For example, in certain embodiments, it may not be necessary to angle any of the nibs, but merely to configure one or more of them at different lengths, so that an array of nibs can overall create a flat plane where the individual nibs are still substantially straight along their lengths, for example, as seen in FIG. 14.

Writing Instrument

[0064] As discussed above, in certain embodiments, a writing instrument herein is configured to include an ink device as described herein. In certain embodiments, a writing instrument can include a barrel that includes other items, e.g., a spring, a mechanical apparatus to facilitate switching of different features of an ink device herein, such as the cartridges, nibs, or ink colors. In certain embodiments, other features can be incorporated into a writing instrument herein, including, for example, an eraser, ink having special features (e.g., visual features such as fluorescence or glitter, ink that provides a particular smell, or disappearing ink).

[0065] In certain embodiments, a writing instrument herein is configured to include one or more styluses as described herein. Each stylus 8 can comprise a rod with at least two ends 12. In certain embodiments, each end 12 of stylus 8 can comprise one or more nibs 5 provided to create a signal on the substrate on which a writing is taking place. In certain embodiments, as shown for example in FIGS. 13 and 14, a stylus 8 can comprise two or more ends, wherein each end is provided with one or more nibs 5 configured to create a signal on the signal-receiving substrate.

[0066] A writing instrument having multiple ends herein can be shaped in various structural configurations to facilitate multiple points of contemporaneous contact with a substrate. In other embodiments, a writing instrument having multiple ends herein can be shaped to allow only one end of the writing instrument to contact the substate. For example, as shown in FIGS. 13-15, in certain embodiments, a writing instrument having multiple ends can have a U-shaped configuration having two parallel ends, a triangular-shaped configuration having three ends, a forked structure having two or more ends extending from the rod, e.g., laterally or radially, or a branched structure (e.g., Y or T-shaped structure) with two or more distinct ends.

[0067] In certain embodiments, a writing instrument herein comprises an electronic stylus having a retracted position and an extended position. In certain embodiments, a writing instrument herein can comprise one or more of: (a) an electronic stylus having a retracted position and an extended position; or (b) a ball point ink cartridge having a retracted position and an extended position; or (c) a housing, wherein the electronic stylus and the ball point ink cartridge are configured within a barrel of the writing instrument to be individually selectable to cause the electronic stylus and the ball point ink cartridge to move from a retracted position to an extended position and from an extended position to a retracted position.

[0068] Although the present technology has been described in relation to embodiments thereof, these embodiments and examples are merely exemplary and not intended to be limiting. Various modifications and alterations to the described embodiments will be apparent to those skilled in the art. The present technology should, therefore, not be limited by the specific disclosure herein, and can be embodied in other forms not explicitly described here, without departing from the spirit thereof.
