The present disclosure relates to a handheld utensil, and more particularly, to a handheld utensil, such as a pen, capable of self-righting to a vertical orientation upon being dropped, thrown, or otherwise moved onto a flat or substantially flat surface.
Handheld utensils are used every day to make people's lives easier. Certain utensils, such as forks and spoons, assist in the delivery of food from a plate or bowl to a person's mouth. Similarly, other utensils, such as pens and pencils, allow a person to write, draw, or otherwise record anything he or she wishes on a paper or substrate. Still further utensils such as toothbrushes allow a user to easily clean his or her teeth and gums. The quality of being handheld makes a utensil easy to use, maintain, and store.
However, given that handheld utensils are generally relatively small objects, it is easy for them to become lost or misplaced, or otherwise become buried underneath larger objects. For example, a user of a pen may set down the pen upon finishing a sentence, but later, after numerous papers have been placed over the pen, when the user subsequently requires it again, he or she may be unable to locate it underneath the papers. As such, it is desirable for a handheld utensil to provide some easy means of permitting its user to locate it in a short time, and it is further desirable that such means be inexpensive and not interfere with the character or operation of the utensil.
An option for solving the aforesaid problem is by introducing a self-righting or biasing element to the handheld utensil. A first solution for providing a self-righting handheld utensil is shown in U.S. Pat. No. 6,200,052 as a balancing pen. The disclosed balancing pen includes a bulb having a center of mass therein and rounded underside for balancing the pen when not in use, which bulb separates from the pen when the user requires use thereof. That is, the user may replace the pen within the bulb when same is not in use, and the bulb maintains the pen in a generally upright orientation. Regardless, this disclosure fails to teach a self-righting handheld utensil wherein the portion providing the self-righting feature remains coupled to the utensil itself during operative use of the utensil. In other words, should the user misplace the bulb while using the disclosed writing implement, this prior art disclosure would cease to operate as intended (in that the disclosed writing implement could no longer self-right).
Thus, while existing solutions show some self-righting features, various drawbacks, including those mentioned above, remain.
Consequently, there exists a need for a handheld utensil that self-rights itself to an upright vertical orientation when placed on a flat or substantially flat surface, and which comprises a weighted element as a base for providing for the self-righting features that does not need to be uncoupled from the use portion of the utensil in order for a user to operatively use the utensil.
In view of the foregoing disadvantages of the prior art, a self-righting handheld utensil configured to include all the advantages of the prior art and to overcome the drawbacks inherent therein is provided. It is an object of the present disclosure to provide a self-righting handheld utensil that comprises a weighted element as a base having a generally convex bottom end so as to provide for an automatic balancing of the utensil to an upright vertical orientation when placed on a flat or substantially flat surface, i.e. without the need for user intervention or application of any external force. It is further an object of the present disclosure to provide a self-righting handheld utensil wherein the weighted element does not need to be uncoupled from the remainder of the utensil (i.e., the use portion thereof) in order for the user to operatively use the utensil.
In an embodiment, a self-righting handheld utensil comprises a weighted element having a top end and a bottom end, the bottom end being generally convex; a an elongated region extending outwardly from the weighted element, the elongated region having a first end and a second end, the first end being in communication with the top end of the weighted element, the elongated region capable of being held by a user; and a use portion disposed on the second end of the elongated region, wherein the weighted element is capable of counterbalancing the utensil to an upright vertical orientation with respect to a flat or substantially flat surface supporting the utensil without the need for user intervention or an application of an external force, resulting in the elongated region and the use portion becoming oriented vertically with respect to the flat or substantially flat surface supporting the utensil, and wherein the utensil may be used without the weighted element first having to be separated from the elongated region or the use portion.
Further alternatives and embodiments are herein contemplated. In a further embodiment, at least a portion of the first end of the elongated region is received within at least a portion of the top end of the weighted element. In another embodiment, at least a portion of the top end of the weighted element is received within at least a portion of the first end of the elongated region. In another embodiment, the top end of the weighted element comprises one of a flat surface, a generally concave surface, and a generally convex surface. In another embodiment, the weighted element comprises at least one of a metal, metal alloy, sand, rubber, plastic, liquid, stone, silicone, oil, wood, gel, soil, and a processed material comprising one or more of the foregoing. In another embodiment, the utensil is one of a pen, pencil, marker, crayon, eraser, highlighter, toothbrush, fork, and spoon. In another embodiment, the utensil further comprises an internal element disposed within at least a portion of the elongated region and the use portion, the internal element containing a chamber suitable for containing at least one of ink, lead, graphite, and wax. In another embodiment, the elongated region and use portion are removably attached to the weighted element via a coupling, such as a threading, snap-fit engagement, and mechanical interference.
These together with other aspects of the present disclosure, along with the various features of novelty that characterize the present disclosure, are pointed out with particularity in the claims annexed hereto and form a part of the present disclosure. For a better understanding of the present disclosure, its operating advantages, and the specific objects attained by its uses, reference should be made to the accompanying drawings and detailed description in which there are illustrated and described exemplary embodiments of the present disclosure.
The advantages and features of the present invention will become better understood with reference to the following detailed description and claims taken in conjunction with the accompanying drawings, wherein like elements are identified with like symbols, and in which:
Like reference numerals refer to like parts throughout the description of several views of the drawings.
The best mode for carrying out the present disclosure is presented in terms of its preferred embodiments, herein depicted in the accompanying figures. The preferred embodiments described herein detail for illustrative purposes are subject to many variations. It is understood that various omissions and substitutions of equivalents are contemplated as circumstances may suggest or render expedient, but are intended to cover the application or implementation without departing from the spirit or scope of the present disclosure.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
The present disclosure comprises a handheld utensil capable of self-righting itself to a vertical orientation upon being dropped, thrown, or otherwise moved. The utensil comprises a weighted element, an elongated region extending outwardly from the weighted element, and a use portion disposed on an end of the elongated region distal from the weighted element. The weighted element may be of any geometric shape provided that it has a generally convex bottom end.
The elongated region is capable of being held by a user and may itself comprise a handle or otherwise graspable portion of the embodied utensil. The use portion comprises the specific part of the utensil operated by or for the user, such as the portion of a pen from which ink is drawn, the spokes of a fork that retain collected food, or the bristles of a toothbrush that make contact with and clean a user's teeth and gums. The elongated region may further include an internal element disposed therein, for example, as an ink cartridge. In an embodiment, the internal element is removably disposed within the elongated region. In a further embodiment, the elongated region and use portion of the utensil are removably attached to the weighted element. Notwithstanding the particular embodiment of the present disclosure, it will be apparent that the elongated region and use portion in combination must comprise a lesser mass than that of the weighted element in order for the disclosed self-righting effect of the weighted element to occur.
At any time when the user has finished using the disclosed utensil, he or she may simply toss, throw, drop, or otherwise move it away from his or her person without having to place the utensil in a particular rest position. That is, upon being so displaced on a flat or substantially flat surface, and regardless of the utensil's orientation at the time the user displaces same, the weighted element, by virtue of its generally convex bottom side and mass, directs the utensil into an upright vertical orientation without the need for user intervention or application of any external force. By way of further benefit, the present disclosure teaches allowing a user to operate the disclosed utensil without having to first remove the weighted element (i.e., that the weighted element may remain attached while the utensil is in operative use), which prevents the user from misplacing or losing the weighted element while separated from the remainder of the utensil. The present disclosure may conceivably pertain to any relatively lightweight, handheld utensil, most notably a pen, a similar writing tool, or a toothbrush, noting that the embodiments discussed herein are intended to be non-exhaustive.
Referring now to
A weighted element 16 is disposed at an end of the utensil 100 distal from the use portion 10 thereof. A top end 18 of the weighted element 16 is in communication with at least a portion of a first end 14 of the elongated region 12. Although the figure depicts the first end 14 as being received within a portion of the top end 18 of the weighted element 16, it is contemplated and understood that communication between the first end 14 of the elongated region 12 and the top end 18 of the weighted element 16 may be defined as the mere contacting of those components or instead as an intersection thereof (e.g., wherein one such component is partially received by the other, such as is shown in the figure).
It will be apparent that, in order for the disclosed counterbalancing function to operate as intended, the weighted element 16 must be of a mass greater than that of the combined mass of the elongated region 12 and use portion 10 of the utensil 100. Notwithstanding that the figure depicts the weighted element 16 as comprising plastic or a processed material comprising plastic, it is understood and contemplated that the weighted element 16 may comprise a metal, metal alloy, sand, rubber, plastic, liquid, stone, silicone, oil, wood, gel, soil, a processed material comprising one or more of the foregoing, or any other combination thereof.
The weighted element 16 may comprise any geometric shape provided that the bottom end 20 thereof has a generally convex surface. That is, and as will be discussed below, it will be apparent that, in order to operate as intended, the weighted element 16 must have a generally rounded bottom end 20. Separately, the top end 18 of the weighted element 16 may comprise any of a flat surface, a generally concave surface, and a generally convex surface. It is understood that the weighted element 16 may in fact comprise any suitable geometry wherein the bottom end 20 thereof is generally rounded, provided that the mass of the elongated region 12 (including the use portion 10 of the utensil 100) remains less than that of the weighted element 16.
As shown in
As shown in
In use, the user may operate the utensil 100 as desired without first having to separate any components thereof, such as by uncoupling the weighted element 16 with the elongated region 12 and use portion 10. In this way, the risk of misplacing any separated components is eliminated. Once the user has finished using the utensil 100, he or she may toss, throw, drop, or otherwise move it away from his or her person without having to place it in a particular rest position. The disclosed utensil 100, upon being so displaced on a flat or substantially flat surface, will be directed to an upright vertical orientation wherein, as a result of the self-righting mechanism, the use portion 10 becomes pointed upwardly relative to said flat surface, which makes the utensil 100 more readily available and identifiable to the user for future use. In that the use portion 10 of the utensil 100 may be used without first having to separate the elongate region 12 or any other portion of the utensil 100 from the weighted element 16, the risk of the user losing or misplacing the weighted element 16 while the utensil 100 is in operative use is entirely eliminated.
The foregoing descriptions of specific embodiments of the present disclosure have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present disclosure to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiment was chosen and described in order to best explain the principles of the present disclosure and its practical application, to thereby enable others skilled in the art to best utilize the disclosure and various embodiments with various modifications as are suited to the particular use contemplated.
The present application is a continuation-in-part of and claims priority under 35 U.S.C. §120 on the pending U.S. patent application Ser. No. 14/627,001, filed on Feb. 20, 2015, the disclosure of which is incorporated by reference.
