The presently disclosed subject matter is directed to a system that includes elements used as an aid for the proper gripping of a handheld instrument (e.g., pencil) used for writing, drawing, and the like. The disclosed system inhibits writing fatigue and helps users to hold a pen or pencil correctly.
When first learning how to write and draw, many children struggle with holding the writing implement (e.g., a pencil) in an appropriate manner. Specifically, the fine motor skills of children develop from large muscle (gross motor) to small muscles (fine motor). In addition, young children have not developed the bone structure that allows for completed joints. Particularly, because their bones have not completely developed, the joints of children include gaps. As a result, a child may be unable to grip a pencil, may improperly hold the pencil using their fist, or may use a variation of another immature and inefficient grasp to hold and manipulate the pencil. Thus, inefficient patterns can develop, such as a thumb wrap, index hook, thumb hyperextension, finger hyper flexion and/or a fisted grasp pattern. Such undesirable patterns negatively affect grasp and handwriting even after muscles have matured and bones have closed the gap at the joints.
A variety of devices have been developed to help a child improve his or her grip. However, prior art gripping devices have various shortcomings and generally fail to promote proper grip positioning techniques. For example, prior art grips commonly require the children to grasp large portions of the grip to increase the surface area, facilitating inefficient habits. Other prior art grips include a divider between fingers to trap fingers in place. However, the dividers do not address the problem of proximal control. Further, users can still grasp inefficiently and wrap the fingers over the barrier. Still other prior art grips merely position the thumb, index, and middle fingers, leaving the other fingers improperly positioned to maintain the correct pencil-holding posture. It would therefore be beneficial to provide a grip that overcomes the shortcomings of the prior art.
In some embodiments, the presently disclosed subject matter is directed to a corrective gripping system. The system comprises a base defined by a first end and a second end. The base further includes a central indentation position about a width of the base, sized and shaped to accommodate a middle finger, index finger, and thumb of a user.

The previous summary and the following detailed descriptions are to be read in view of the drawings, which illustrate some (but not all) embodiments of the presently disclosed subject matter.
The presently disclosed subject matter is introduced with sufficient details to provide an understanding of one or more particular embodiments of broader inventive subject matters. The descriptions expound upon and exemplify features of those embodiments without limiting the inventive subject matters to the explicitly described embodiments and features. Considerations in view of these descriptions will likely give rise to additional and similar embodiments and features without departing from the scope of the presently disclosed subject matter.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the presently disclosed subject matter pertains. Although any methods, devices, and materials similar or equivalent to those described herein can be used in the practice or testing of the presently disclosed subject matter, representative methods, devices, and materials are now described.
Following long-standing patent law convention, the terms “a”, “an”, and “the” refer to “one or more” when used in the subject specification, including the claims. Thus, for example, reference to “a device” can include a plurality of such devices, and so forth.
Unless otherwise indicated, all numbers expressing quantities of components, conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about”. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the instant specification and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by the presently disclosed subject matter.
As used herein, the term “about”, when referring to a value or to an amount of mass, weight, time, volume, concentration, and/or percentage can encompass variations of, in some embodiments +/−0.1-20% from the specified amount, as such variations are appropriate in the disclosed packages and methods.
The presently disclosed subject matter can be implemented in several different forms. However, the present disclosure of such embodiments is to be considered an example of the principles and are not intended to limit the invention to the specific embodiments shown and described. Like reference numerals are used to describe the same, similar, or corresponding part in the several views of the drawings. The detailed description defines terms used herein and specifically describes embodiments for those skilled in the art to practice the presently disclosed subject matter.
The presently disclosed subject matter is generally directed to a system that can be used to properly align a user's hand when gripping a writing implement. The term “writing implement” refers to any element that can be used for writing, such as (but not limited to) pencils, pens, markers, chalk, highlighters, and the like. The disclosed system includes four separate elements that combine in specific ways to grow and/or build a mature grasp. Specifically, the individual elements can be used separately or mixed and matched to customize a grip and discussed in more detail below.
As described above, the gripping system includes several components that can individually or in combination be used with a writing implement.
The base includes interior bore 83 that passes from the first end to the second end of the base, through the base interior. The term “bore” refers to an internal cavity or passageway that extends through the interior of the base. The bore is sized and shaped to allow the base to pass over the external surface of a writing implement, as shown in
As shown, the base can include central indentation 95 that accommodates the size and shape of a user's fingers. One or more indentations can be positioned to circle around the central surface of the base (e.g., about halfway between the first and second ends). Indentations 95 help secure the user's index finger 45, middle finger 50, and thumb 40 in a position that is comfortable, while also allowing the user to grip the writing implement. The indentations are large enough to allow the thumb and fingers to move slightly if readjustment is needed in case of fatigue yet remain within the proper alignment position for use. The base therefore functions to increase the surface area of the writing utensil without controlling the exact location of the user's fingers, as shown in
In some embodiments, indentations 95 can include textured regions 96 to enhance the tactile properties of base 10, as shown in
The base has length 100, width 101, and/or thickness of about 0.5-3 inches (e.g., at least/no more than about 0.5, 1, 1.5, 2, 2.5, or 3). The term “length” refers to the longest straight line horizontal distance (e.g., the distance from base first end 90 to second end 91). The term “width” refers to the longest straight line vertical distance of the base. The term “thickness” refers to the support dimension perpendicular to both the length and width. It should be appreciated that the length, width, and thickness of base 10 can be greater or less than the ranges given herein, such as to adjust the device for smaller or larger sized hands (e.g., petite or larger users).
Although depicted with a round cross-sectional shape in the Figures, base 10 is not limited and can include any desired cross-sectional shape (e.g., square, rectangular, oval, triangular, abstract).
The handle includes first and second bores 110, 111 that extend through the handle to accommodate a pencil, as shown in
As described, the slender handle main body is sized and shaped to be positioned within user palm 35. For this reason, the handle body can be thin and can include width 117 of about 0.5-2 inches (at least/no more than about 0.5, 1, 1.5, 2 inches). The handle can further have any desired length 116, such as about 1-5 inches (e.g., at least/no more than about 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or 5 inches) from first end 105 to second end 106. However, it should be appreciated that the presently disclosed subject matter is not limited and can be configured in any desired dimensions.
Handle 15 further includes a pair of connectors 120 that allow for the releasable attachment of web support 20, as shown in
The web support can have length 125 and/or width 126 of about 0.5-1.5 inches (e.g., at least/no more than about 0.5, 1, or 1.5 inches), as shown in
Web support 20 includes connectors positioned on the interior surface of the element (e.g., adjacent to the outer surface of the handle) that cooperate with the handle connectors to allow for releasable attachment of the web support, as shown in
It should be appreciated that handle 15 and web support 20 are optional, and a user can employ base 10 without the handle and/or web support attached. When handle 15 is not needed, the disclosed gripping device can employ independent web positioner 25 that can be used alone or with base 10.
The independent web positioner can include internal bore 135 that extends through first end 130 that is sized and shaped to receive a writing implement, such as a pen or pencil. In some embodiments, bore 135 can have a circular cross-sectional shape. However, the presently disclosed subject matter is not limited and can be configured in any desired shape that accommodates a writing implement, such as (but not limited to) hexagonal, octagonal, and the like. The length of the writing implement can be securely accommodated by bore 135, such that tip 82 extends beyond the base first end, as shown in
The independent web positioner bore can have any desired diameter, such as about 0.1-1 inch (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1 inch). In some embodiments, bore 135 can be configured to be slightly smaller than the outer circumference of writing implement 5 to allow the independent web positioner to be frictionally held in place when the base is in use. As with the bore of base 10, the independent web positioner bore can also include one or more non-skid elements 136 to resist movement of the support relative to the writing implement, as shown in
The independent web positioner has length 140 and/or width 141 of about 0.5-2 inches (e.g., at least/no more than about 0.5, 0.75, 1, 1.25, 1.5, 1.75, or 2 inches). The term “length” refers to the longest straight line horizontal distance (e.g., the distance from the independent web positioner first end 130 to second end 131). The term “width” refers to the longest straight line vertical distance of the base. However, it should be appreciated that the length and width of independent web positioner 25 can be greater or less than the ranges given herein, such as to adjust the device for smaller or larger sized hands (e.g., petite or larger users).
The independent web positioner can include one or more ridges 142 that accommodate the size and shape of a user's thumb and index finger. Specifically, a ridge can be sized and shaped for the placement of the exterior portion and underside of a user's thumb 40. Similarly, the independent web positioner can include a ridge sized and shaped to accommodate the interior portion and underside of a user's index finger 45. The independent web positioner therefore provides for the placement of a user's index finger to oppose thumb 40 in a comfortable manner. Ridges 142 can be contoured in a concave manner, forming an indentation or depression as shown in the Figures. The independent web positioner can include 1, 2, 3, 4, 5, or more ridges. The ridges help secure the index finger and thumb in a position that is comfortable, while also allowing the user to grip the writing implement. The ridges are large enough to allow the thumb and index finger to move slightly if readjustment is needed in case of fatigue yet remain within the proper alignment position for use. The base therefore functions to increase the surface area of the writing utensil without controlling the exact location of the user's fingers.
In some embodiments, one or more of the independent web positioner ridges or surfaces can include textured regions 13, as shown in
It should be appreciated that the size of the various components of the disclosed system can be varied depending on a user's age, gender, and handedness. As a result, the system can be adapted for use by preschool children, primary school students, secondary school students, teenagers, adults, males, females, and so forth.
One or more components of the system can include markings or decorations. Since the device is commonly used with children, the device can include animal markings (spots, zebra stripes, etc.), glitter, sequins, and the like. Further, the various components of the disclosed gripping device can be configured in any desired color or pattern.
To ensure full functionality, the device can be configured for either the right hand or the left hand of the user. For example, the Figures depict a device suitable for use by the right hand. However, the left-handed version of the system can be a mirror image of the embodiments shown.
The components of system 1 can be constructed from a wide variety of materials. For example, one or more components can be constructed from rigid materials, such as one or more metal (e.g., stainless steel, steel, copper, titanium, platinum, gold, silver), fiberglass, rigid plastic, ceramics, glass, and the like. In some embodiments, one or more components of the device can be constructed from flexible materials, such as paper, cardboard, paperboard, rubber, composite materials, polyethylene terephthalate (PET), high-density polyethylene, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polystyrene (PS), high impact polystyrene (HIPS) and polycarbonate (PC), silicone, or combinations thereof. Conveniently, the device can be manufactured by a molding process or using any other method known or used in the art.
In some embodiments, independent web positioner 25, handle 15, web support 20, and base 10 are made from the same material(s). However, the presently disclosed subject matter is not limited and the materials of one component can differ from the materials of at least one other component.
In use, base 10 can be configured on writing implement 5, as shown in
In some embodiments, handle 15 can also be attached to the writing implement through bore 110 or 111. It should be appreciated that handle 15 is optional, and the base can be used without attachment of the handle. In some embodiments web support 20 can be releasably connected to the handle, as shown in
Optionally, the handle can be used alone, without the web support, independent web positioner, and/or base, as illustrated in
When handle 15 is not needed, independent web positioner 25 can be used with base 10 or alone, as shown in
A user can use the disclosed system 1 to correct the writing implement posture. Specifically, the base increases the surface area of the writing utensil, allowing it to be more easily grasped by the user. The user's thumb and index finger can be positioned within the indentations on the base, allowing for comfortable positioning during use. Handle 15 continues the grip into the user's palm and provides a structure for the middle, ring, and pinkie fingers to rest. The web support can be positioned on the handle at the base of the user's thumb or web space. Web support 20 stabilizes the user's thumb to prevent hyperextension and supports the metacarpophalangeal joint. As a result, the user's thumb is in a functional position. The independent web positioner can be used when the handle is not needed. Specifically, the base creates a large diameter for the user's index fingertip, middle finger fingertip, and thumb to grip. The larger diameter gripping space places the index finger, middle finger, and thumb in an ergonomically correct position for stability and movement.
The disclosed system offers many advantages over prior art devices. For example, device 5 can be customized as desired by the user. Particularly, independent web positioner 25, handle 15, web support 20, and base 10 can be combined in specific ways to group or build a mature grasp. Therefore, the device is customizable to support the needs of a particular user.
The system can be enjoyed by a variety of users, including children, teenagers, adults, and the like.
Advantageously, the base increases the surface area of writing implement 5 without controlling the exact location of the user's fingers. In this way, the user maintains a comfortable feel during use of the device.
Further, the handle continues the grip to the user's palm and supports the palmar arch, as well as provides a resting position for the fingers. Accordingly, the handle allows a full grasp with the fingers and hand in a functional position.
Web support stabilizes the web space of thumb 40 to prevent hyperextension and supports the metacarpophalangeal joint to place the thumb in a functional position.
The disclosed gripping device is small and easily portable, allowing a user to carry the device from one location to another.
Although the presently disclosed subject matter has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
