The present disclosure relates generally to writing utensils. More particularly, the present disclosure relates to a writing utensil adapted to aid a user in the development of a tripod writing grip.
There are individuals that are unable to successfully grasp standard writing utensils using a tripod writing grip, or who which may be able to do so only with great difficulty. These individuals may lack muscle, fine motor, or other ability that inhibits their ability to grasp. Often, these individuals are apt to use a power grip, opposed to a standard tripod grip, and such practices may limit their ability to write or draw in an efficient and legible manner and may develop into habits which may hinder the development of a tripod writing grip.
Current devices for promoting a proper writing grip are usually provided as add-ons for standard writing utensils. Such devices generally either provide only limited grip options or do not adequately prevent a user's hand or the device itself from sliding up and down the writing utensil. Accordingly, there is a need for an adaptive writing utensil which addresses some or all of these deficiencies in the prior art.
In order to address the foregoing issues, a writing utensil is provided which has been adapted for promoting the development of a tripod writing grip. In various examples, the writing utensil may have an elongate body including three faces extending between a proximal end and a distal end thereof and a boss member extending from an intermediate portion thereof, with the boss member being adapted for impeding a user's fingers from sliding along a longitudinal axis of the elongate body.
In various examples, the above-described intermediate portion may be located at approximately the midpoint between the proximal end and distal end of the elongate body. In further examples, the intermediate portion may be located at a distance, in a range from approximately ⅛ to ½ of the total length of the elongate body, from the distal end of thereof. In further examples, the intermediate portion may be located at a distance of approximately ¼ of the total length of the elongate body, from the distal end thereof.
In various examples, the thickness of the boss member may be approximately 1/12 to ⅛ of the total length of the elongate body and/or may be approximately ¼ to ¾ inch.
In various examples, the boss member and the elongate body may be formed as a unitary structure of the same material and/or may be made of at least one of the following wax, charcoal, chalk, grease, or any combination thereof. In further examples, the boss member and elongate body may be made of paraffin wax.
In non-limiting embodiments, each of the proximal end and the distal end of the elongate body may include a marking surface. In various examples the cross section of the elongate body may be substantially triangular, and, in particular, in the form of a substantially equilateral triangle. In various configurations, the boss member may contact only two faces of the elongate body, and a non-contacted face may be substantially flat.
In certain non-limiting embodiments, the elongate body may include a longitudinal cavity adapted for receiving a marking implement, which, in various examples, may include a crayon, a chalk, an ink source, a pencil lead (e.g., a stick of compressed graphite), a computer stylus, or any combination thereof.
In further non-limiting embodiments the marking implement may include a conventional writing utensil adapted for use apart from the writing utensil, such as, in various examples, a pen, a pencil, a marker, a crayon, a computer stylus, or any combination thereof.
In various examples, the distal end of the elongate body may be provided with at least one of the following: an eraser, a thruster configured to actuate an extension and retraction mechanism of the marking implement, or any combination thereof.
In various examples the boss member may be provided such that it is in contact with no more than two faces of the elongate body, and a third face of the elongate body may substantially flat along its entire length.
In various examples, the boss member may have a substantially rectangular cross section extending upward from two bottom edges of the elongate body, wherein a top face of the boss member is even with or extends past a top edge of the elongate body. In other illustrative examples, the boss member may extend around each face of the elongate body, or may extend from only one face of the elongate body. In further examples, the boss member may be bifurcated such that two boss members are provided, each extending from a different face of the elongate body.
In further non-limiting embodiments, at least a portion of the elongate body may include four or more faces. For example, in non-limiting embodiments at least a portion of the elongate body may have a trapezoidal, rhomboidal, pentagonal, hexagonal, heptagonal, octagonal, trapezoidal, rhomboidal, pentagonal, hexagonal, heptagonal, or octagonal cross section.
In further non-limiting embodiments of the present invention, a mold may be provided for forming a writing utensil as described herein. In non-limiting embodiments, the mold may comprise: a plurality of elongate channels, each channel defining at least two cavities extending along a longitudinal axis thereof, wherein each of the at least two cavities corresponds to a shape of the writing utensil, and wherein each of the at least two cavities is separated from at least one adjacent cavity by at least one groove extending along a transverse axis of the plurality of elongate channels.
In further non-limiting embodiments of the present invention, a method may be provided for forming a writing utensil as described herein. In non-limiting embodiments, the method may comprise: providing a mold comprising a plurality of elongate channels, each channel defining at least two cavities extending along a longitudinal axis thereof, wherein each of the at least two cavities corresponds to a shape of the writing utensil, and wherein each of the at least two cavities is separated from at least one adjacent cavity by at least one groove extending along a transverse axis of the plurality of elongate channels; supplying a material for forming at least one of the plurality of writing utensils into at least one of the at least one cavity; and inserting at least one removable spacer into at least one of the at least one groove, such that the at least one removable spacer separates at least one of the at least one cavity from an adjacent one of the at least one cavity. In non-limiting embodiments, the at least one removable spacer may be inserted either before the material is supplied to the at least one cavity or after the material is supplied to the at least one cavity.
These and other features and characteristics of the adaptive writing utensil, as well as, the methods of operation and functions of the related elements of structures and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the invention.

With reference to
In non-limiting embodiments, the thickness of the boss member 12 may be approximately ¼ to ½ inch, or about 1/12 to ⅛ of the total length of the elongate body 10. For example, in a non-limiting embodiment, the boss member 12 may have a thickness of approximately ½ inch, with the total elongate body 10 being approximately 4½ inches long, such that the thickness of the boss member 12 is approximately 1/9 of the total length of the elongate body 10. It will be appreciated that various adjustments may be made in order to accommodate users having different hand sizes.
In the non-limiting embodiment shown in
In non-limiting embodiments, at least a portion of the adaptive writing utensil 100 may be formed as a stick of colored wax, charcoal, chalk, grease, or any combination thereof, or may be formed as a computer stylus or other electronic or virtual marking implement. For example, in one non-limiting embodiment, the writing utensil 100 may be formed from colored or otherwise pigmented paraffin wax, and the finished product may be formed as a crayon or wax pastel. It will be appreciated that the present disclosure is not limited to these illustrative examples, and that many types of marking materials known to those skilled in the art may be utilized in accordance with the present invention.
In non-limiting embodiments, the adaptive writing utensil 100, including the boss member 12 and elongate body 10 may be a unitary structure formed of the same material and may be formed together in a single mold, in order to facilitate efficient manufacturing and to produce a unified tactile structure which may be desirable to an end user. In non-limiting embodiments, the adaptive writing utensil 100 may be advantageously formed all or in part from recycled conventional crayons (e.g., pastels made of paraffin wax or like material), which may be melted and formed in an appropriate mold.
However, it is to be understood that the present invention is not solely limited to this embodiment, and various other structures are permissible. For example, in a non-limiting embodiment, the elongate body 10 may be made of paraffin wax or other marking material as described herein and the boss member 12 may be made of plastic, wood, metal, or other durable material and may be affixed to the elongate body 10 using an adhesive, a “snap-fit” mechanism, or any combination thereof.
In non-limiting embodiments utilizing, a snap-fit mechanism, one or more spikes, lugs, or other type of protuberances, may be located on the interior of the boss member 12 to aid the boss member 12 in remaining in place. However, in other non-limiting embodiments utilizing a snap-fit mechanism, a combination of the force exerted on the boss member 12 due to the resiliency of the snap-fit mechanism and the force of friction maybe sufficient to maintain the boss member 12 in its desired position. In certain non-limiting embodiments, the snap-fit mechanism may be such that the boss member 12 may be releasably attached to the elongate body 10 and moved to a desired position along the elongate body 10 to accommodate the needs of individual users.
With continued reference to
In the non-limiting embodiment shown, a textured surface 6 is provided on each face of the elongate body 10 to further aid in gripping. As illustrated in
Additionally, in non-limiting embodiments, a particular texture may be associated with a particular color or type of marking utensil. In such embodiments, the various textures may aid persons with a visual impairment in selecting an appropriate writing utensil for the task at hand. Additionally or alternatively, a plurality of writing utensils may be provided together with different shaped boss members, each associated with a different color or type of utensil.

In the non-limiting illustrations shown, the boss member 12 approximately bisects the elongate body, and thus allows for a variety of different gripping positions depending on an individual's particular needs. For example, as shown in
As shown in
With reference to
In the non-limiting embodiment shown in
Optionally, a user may leave the distal end of the conventional writing implement exposed and utilize only the proximal half 200 of the holder. Alternatively, the distal half 202 may be added to form an assembled writing utensil as shown in
As shown in
This provides various benefits, such as limiting the exposure of the hand to a marking surface which may be distally oriented. Further, in particular in embodiments wherein the adaptive writing utensil is in the form of a wax pastel (e.g., a crayon), chalk, or other type of marking implement which wears down with continued use, the case may be used to maintain the tactile feel of the original adaptive writing utensil by providing a triangular cross section on the distally oriented side and may thus extend the life of the adaptive writing utensil.
In the non-limiting embodiment shown, an extension portion 21 corresponding to the thickness of the boss member 12 is provided on one side of the proximal half 300 such that it covers the portion of the elongate body 10 which is opposite to the boss member 12 when the case is in place. In alternative non-limiting embodiments, the length of the extension portion may be split among the proximal half 300 and distal half 302 of the case (e.g., two half-extension portions which come together opposite of the midpoint of the boss member 12), or a gap may be left at this location.
Referring now to
In the non-limiting embodiment shown, each cavity 704 corresponds to the shape of an adaptive writing utensil, as described herein. For example, in the non-limiting embodiment shown, each cavity 704 contains a boss member portion 708 corresponding to the shape of a boss member of an adaptive writing utensil, as described herein, such that a boss member may be formed integrally with each adaptive writing utensil in its respective cavity 704.
Referring now to
In non-limiting embodiments, removable spacers 710 may be placed in each groove 706 prior to filling the mold 700 with a forming material (e.g., paraffin wax) for forming adaptive writing utensils, such that each cavity 704 may be filled separately. Such non-limiting embodiments may allow for multiple different adaptive writing utensils made of different materials (e.g., different colors of paraffin wax) to be formed at once in a single mold 700.
In other non-limiting embodiments, the forming material may be supplied (e.g., poured into or injected into) to the entire mold 700 at once, and the removable spacers 710 may be emplaced during formation of the adaptive writing utensils such that they displace the forming material from the grooves 706 and thus separate each adaptive writing utensil from any adjacent adaptive writing utensils in its respective channel during formation. Such non-limiting embodiments may allow for more efficient manufacture of a number of adaptive writing utensils made of the same forming material by reducing the number of instances in which forming material is introduced into the mold (e.g., by allowing for one large pouring or injection of forming material per use of the mold rather than requiring multiple smaller pourings or injections).
Although the invention has been described in detail for the purpose of illustration based on what are currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
This application claims priority to U.S. Provisional Application Ser. No. 62/488,348, filed Apr. 21, 2017, which is hereby incorporated by reference in its entirety.
