This disclosure relates generally to writing instruments, and in particular, relates to writing instruments having fibrous nibs.
Writing instruments with fibrous nibs, such as markers, pens, and highlighters, are commonly used for transferring ink to a writing surface. When a wide line is desired, a writing instrument having a fibrous nib with a sufficiently wide surface is selected so that only a single pass of the writing instrument is required to form the wide line. Unfortunately, when a right-handed user draws a line from left to right, the writing instrument and nib obstruct the view of the writing surface. A wide fibrous nib for drawing a wide line exacerbates the problem by obstructing an even greater amount of the writing surface. The problem is particularly acute when a highlighter pen is used to highlight text. To compensate, users will often draw multiple short lines instead of one long line, or draw the line while holding the writing instrument at an unnatural angle. Without compensation, the line is often misdrawn, either in the wrong place or with an irregular shape.
Prior attempts to provide writing instruments with relatively wide nibs having an improved view of the writing surface utilize a clear support structure that can be viewed through. However, in such instruments, the clear support structure itself presents an obstruction of the view of the writing surface, particularly over time as the clear support structure collects debris, defects, or discoloration.
Thus, writing instruments having fibrous nibs permitting a completely unobstructed view of the writing surface would be beneficial.
In embodiments, the present disclosure describes a nib for a writing instrument. The nib may include a self-supporting fibrous nib body including an upper writing portion and a lower portion in communication with the upper writing portion. The upper writing portion of the fibrous nib body may be configured to deliver ink to a writing surface and define a void in a two-dimensional plane bounded by at least one elongated beam. The void may allow observation of the writing surface therethrough. A first notch may be disposed on a posterior side of the fibrous nib body and a second notch may be disposed on an anterior side of the fibrous nib body. The first notch and the second notch define a boundary between the lower portion of the fibrous nib body and the upper writing portion of the fibrous nib body.
In embodiments, the present disclosure describes a writing instrument. The writing instrument may include an elongated body including an ink reservoir. The writing instrument may include the nib disposed at an end of the elongated body. The lower portion of the fibrous nib body may be disposed inside the end of the elongated body and may be configured to deliver ink from the ink reservoir to the upper writing portion of the fibrous nib body. The upper writing portion of the fibrous nib body may protrude outside of the end of the elongated body.
In embodiments, the present disclosure describes a writing instrument. The writing instrument may include an elongated body comprising an ink reservoir. The writing instrument may further include a ferrule disposed at an end of the elongated body. The writing instrument may further include a nib including a self-supporting fibrous nib body comprising an upper writing portion and a lower portion in communication with the upper writing portion. The upper writing portion of the fibrous nib body may be configured to deliver ink to a writing surface and define a void in a two-dimensional plane bounded by at least one elongated beam. The void may allow observation of the writing surface therethrough. A first notch may be disposed on a posterior side of the fibrous nib body and a second notch may be disposed on an anterior side of the fibrous nib body. The first notch and the second notch may define a boundary between the lower portion of the fibrous nib body and the upper writing portion of the fibrous nib body. The lower portion of the fibrous nib body may be disposed inside the end of the elongated body and be configured to deliver ink from the ink reservoir to the upper writing portion of the fibrous nib body. The upper writing portion of the fibrous nib body may protrude outside the end of the elongated body. The ferrule may include at least one elongated support rib for supporting the at least one elongated beam of the nib.
The detailed description is set forth with reference to the accompanying drawings. The use of the same reference numerals may indicate similar to identical items. Various embodiments may utilize elements and/or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. Elements and/or components in the figures are not necessarily drawn to scale. Throughout this disclosure, depending on the context, singular and plural terminology may be used interchangeably.
Writing instruments and associated nib assemblies are provided herein. The writing instruments and associated nib assemblies advantageously improve the visibility of a writing surface during use of the writing instrument. The present disclosure includes non-limiting embodiments of writing instruments and nibs. The embodiments are described in detail herein to enable one of ordinary skill in the art to practice the writing instruments and associated nib assemblies, although it is to be understood that other embodiments may be utilized and that logical changes may be made without departing from the scope of the disclosure. Throughout the disclosure, depending on the context, singular and plural terminology may be used interchangeably.
Throughout this disclosure, various aspects are presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the disclosure. Accordingly, the description of a range should be considered to have specifically disclosed all the possible sub-ranges as well as individual numerical values within that range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as individual numbers within that range, for example, 1, 2, 3, 4, 5, and 6. This applies regardless of the breadth of the range. A dimension described as being “of” X “to” Y means that end points X and Y are included in the range X-Y. Similarly, “from” X “to” Y means that end points X and Y are included in the range X-Y.
Fibrous nibs are nibs formed out of fibrous materials along which ink may travel. For example, a fibrous material may be formed from a plurality of fibers and a resin, a porous elastomer, or another material. For example, highlighter pens, dry erase markers, permanent markers, felt-tip pens, and the like may use a fibrous nib that generally maintains its shape while allowing ink to travel along the fibers. Since writing instruments such as highlighter pens are often used for creating wide lines, some users experience difficulty in accurately drawing lines with such writing instruments because of the size of the fibrous nib and the opacity of the fibrous nib. In the present disclosure, the fibrous nibs include a void therein, through which a user may view a surface upon which they are writing during a writing action. As such, the present nibs may provide a means by which users can draw wide lines accurately due to the ability to view the writing surface.
Nib assemblies and writing instruments incorporating such assemblies are discussed below. The nibs are fibrous and include a void therein, through which a user may view a surface upon which they are writing during a writing action. The nibs may be produced from a plurality of fibers and resin that are subjected to a punch to define a void through which a writing surface can be viewed in use. By punching out material to form a void, it has been discovered that the nib may continue to transfer ink from an ink reservoir to a writing surface, while providing an unobstructed view of the writing surface. In certain aspects, the nibs are self-supporting such that no additional support of the upper writing portion is necessary. In other aspects, the writing instrument includes a ferrule having a support structure for the nib.
Nib Assemblies
Nibs for writing instruments are disclosed herein. In one aspect, the nib may be formed from a self-supporting fibrous nib body including an upper writing portion and a lower portion that are in communication with each other. The upper writing portion may be designed to deliver ink to a writing surface. The upper writing portion may define a void in a two-dimensional X-Y plane bounded by at least one elongated beam, i.e., the void is both an absence of material therein and an absence of material extending in a third axis such that the void is surrounded by material in only a first and second axis. The void may allow observation of a writing surface therethrough.
As used herein, the term “self-supporting” refers to a nib having sufficient structural stability that it maintains a defined shape in use, absent any supporting structures associated with the upper writing portion thereof, and that is suitable for the transfer of ink.
As used herein, a “void” refers to the absence of any solid material. The void may be filled by air. The shape of the void is defined by the fibrous nib body that defines the void. The void may be any shape, such as a square, triangle, rectangle, or other polygon depending on the application and desired nib dimensions and shape. In some embodiments, the void is formed by punching through the nib.
In some embodiments, the nib is monolithic. As used herein, “monolithic” refers to a single, homogenous structure having a continuous composition throughout. In other embodiments, the nib is formed by two or more portions that are operatively coupled in fluid communication with one another.
In some embodiments, the fibrous nib body is formed from a plurality of fibers and a resin. In other embodiments, the fibrous nib body is formed from a porous elastomer.
In some embodiments, the lower portion and the upper writing portion are defined by a first notch located on an anterior side of the fibrous nib body, and a second notch located on a posterior side of the fibrous nib body. The first notch and second notch are located in the same axis, such that a hypothetical line drawn from one notch to the other notch is perpendicular to a longitudinal axis of the nib and defines a hypothetical boundary that separates the lower portion and the upper writing portion.
In some embodiments, the notches may be positioned such that the lower portion and the upper writing portion are substantially equal in area, i.e., the notches may be positioned at the midpoint of a longitudinal axis of the nib. As used herein, “area” used in reference to comparing areas of the portions of the nib body include void areas that may be included in said portions. In other embodiments, the notches may be positioned such that the lower portion has an area greater than that of the upper writing portion. In other embodiments, the notches may be positioned such that the lower portion has an area lesser than that of the upper writing portion.
In some embodiments, the first notch and second notch extend into the fibrous nib body by about 0.1 mm to about 1.5 mm, for example about 0.2 mm, 0.5 mm, 0.7 mm, 1 mm, 1.2 mm, or about 1.4 mm. The notches could extend 0.15 mm, 0.3 mm, 0.9 mm, 1.3 mm, or any distance in between depending on the desired nib and writing instrument properties. The notches could extend into the fibrous nib body by about 1% of the fibrous nib body width, by about 5% of the fibrous nib body width, or about 10% of the fibrous nib body. The notches could extend into the fibrous nib body by about 2%, 7%, 11%, 15%, 20%, or 25% of the fibrous nib body, or any distance between depending on the desired nib and writing instrument properties.
In some embodiments, the void may be a punched area in the upper writing portion. That is, the void may be mechanically punched from a fibrous nib material to form the fibrous nib body having the void.
In some embodiments, the fibrous nib body has a thickness of about 1 mm to about 4 mm, for example about 1.5 mm, 2 mm, 3 mm, or about 3.5 mm. The fibrous nib body could have a thickness of about 1.8 mm, 2.3 mm, 2.7 mm, 3.4 mm, 3.9 mm, or any thickness in between depending on the desired nib and writing instrument properties.
In some embodiments, the fibrous nib body may include a writing beam located in the upper writing portion superior to the void. In some embodiments, the writing beam has one or more beveled edges so as to increase the surface area of the writing beam that contacts a writing surface in use.
In some embodiments, the writing beam is perpendicular to the longitudinal axis of the fibrous nib body. In other embodiments, the writing beam is positioned at an angle to the perpendicular defined by the longitudinal axis so as to change the effective angle at which the writing instrument is held by a user in use. In some embodiments, the angle is greater than 0° to about 45°, for example about 9.5°.
In some embodiments, the writing beam extends along a longitudinal axis by about 1 mm to about 2.5 mm, for example 1.4 mm, 1.8 mm, 2.2 mm, or about 2.4 mm. The writing beam could extend by 1.2 mm, 1.5 mm, 1.7 mm, 2.1 mm, or any distance in between depending on the desired nib and writing instrument properties.
In some embodiments, the fibrous nib body has a length of about 15 mm to about 30 mm, for example 18 mm, 20 mm, 25 mm, or about 28 mm. The fibrous nib body could have a length of about 16 mm, 21 mm, 27 mm, 29 mm, or any length in between depending on the desired nib and writing instrument properties. In some embodiments, the fibrous nib body has a width of about 5 mm to about 10 mm, for example 6 mm, 7 mm, 8 mm, 9 mm, or any width in between depending on the desired nib and writing instrument properties. In some embodiments, the fibrous nib body has a length-to-width ratio of about 1:1, about 1.5:1, about 2:1, about 2.5:1, about 3:1, about 3.5:1, about 4:1, or any ratio in between depending on the desired nib and writing instrument properties.
The lower portion of the nib body may taper to a substantially triangular point, or the lower portion of the nib body may have a substantially rectangular shape. In some embodiments, the lower portion of the nib body may begin to taper such that the inferior-most 10% of the lower portion, the inferior-most 20% of the lower portion, the inferior-most 30%, 40%, 50%, or any proportion of the lower portion of the nib body in between is part of the tapered end. In some embodiments, the lower portion of the nib body has a width substantially equal to the width of the nib body. In other embodiments, the lower portion has a width lesser than the width of the nib body. In some embodiments, the lower portion transfers a liquid, such as ink, from a source of liquid located inferior to the lower portion of the nib body to the upper writing portion of the nib body.
The anterior and posterior elongated beams may begin to curve towards each other at the point where they meet the writing beam, or they may maintain a straight, unchanging profile when they meet the writing beam. The notches may be rectilinear, the notches may have curved edges, or the notches may have rounded corners. One side of the writing beam may be beveled while the opposite side is not, or both or neither sides may be beveled. The elongated beams may be rectilinear such that a cross-section of the beam is a rectangle, or the elongated beams may have chamfered corners such that a cross-section of the beam is a rounded rectangle.
In some instances, the void may be formed by punching through the nib using a punch having the desired void size and shape. In other instances, the void may be formed by a mold in which the nib is formed, i.e., a nib formed from fibrous material and resin may be formed in a mold designed to produce a nib having a void. Any suitable means for forming the void may be used.
Writing Instruments
Writing instruments are also disclosed herein. In one aspect, the writing instrument may include an elongated body having an ink reservoir and a fibrous nib body, such as the self-supporting fibrous nib body described above. The fibrous nib body may have a lower portion disposed in the end of the elongated body and in fluid communication with the ink contained in the ink reservoir, and an upper writing portion that protrudes from the end of the elongated body such that the fibrous nib body transfers ink from the ink reservoir to a writing surface. The upper writing portion may define a void in a two-dimensional X-Y plane by at least one elongated beam. In another aspect, the writing instrument may include a ferrule at the end of the elongated body for supporting the fibrous nib body. In such embodiments, the fibrous nib body may include any suitable configuration (e.g., materials and structure), including any combination of features described herein, and may be self-supporting or not. Thus, the ferrule may provide the structural support for a non-self-supporting nib body, or may supplement the support provided by a self-supporting nib body.
In some embodiments, the ferrule has at least one elongated support rib for supporting the at least one elongated beam of the nib body. In some embodiments, the ferrule has an anterior elongated support rib for supporting an anterior elongated beam of the nib and a posterior elongated support rib for supporting a posterior elongated beam of the nib.
In some embodiments, the anterior elongated support rib and posterior elongated support rib each include a first groove that corresponds to the anterior elongated beam and the posterior elongated beam so as to support the fibrous nib body and prevent the fibrous nib body from deforming in use. In some embodiments, the anterior elongated support rib and posterior elongated support rib each include a second groove within the first groove that corresponds to a first protrusion on the anterior elongated beam and a second protrusion on the posterior support beam. The second grooves and protrusions further support the fibrous nib body and prevent the nib from deforming or detaching from the ferrule in use.
In some embodiments, the anterior elongated support rib and the posterior elongated support rib are equal in length. In other embodiments, the anterior elongated support rib has a length greater than a length of the posterior elongated support rib.
In some embodiments, the writing instrument is a highlighter. In other embodiments, the writing instrument is a permanent marker. In other embodiments, the writing instrument is a dry-erase marker. In other embodiments, the writing instrument is a pen.
In some instances, the writing instrument may have a round shape. In other instances, the writing instrument may have another shape, such as rectangular, triangular, or some other polygon. Any suitable shape for a writing instrument may be used. In some instances, the writing instrument has a cross-sectional area that substantially corresponds to the size of the line width drawn by the nib, as depicted in
In some instances, the ferrule has a round base where it meets the elongated body. In other instances, the ferrule has a rectilinear base. Any suitable shaped ferrule base may be used. The elongated support ribs of the ferrule may have a curved outer boundary corresponding to similarly curved elongated beams of the nib. The elongated support ribs may extend the entire length of the elongated beams, or the elongated support ribs may extend only a portion of the length of the elongated beams so as to permit a larger portion of the elongated beams to be exposed. In some instances, the elongated support ribs terminate with a flat surface perpendicular to a longitudinal axis of the ferrule. In other instances, the elongated support ribs have a tapered end.
Writing instruments and associated nib assemblies have been provided. These writing instruments include nib assemblies with fibrous nib bodies defining voids through which writing surfaces can be viewed when used. In some embodiments, the nib is self-supporting, while in other embodiments, the nib is supported by a ferrule with one or more elongated support ribs corresponding to one or more elongated beams of the nib.
