Training Chopsticks
Training chopsticks including a lower chopstick having a longitudinal end, an oppositely longitudinal end, an upper side, a lower side, a lateral side, and an oppositely lateral side; an upper chopstick having an upper side, a lower side, a longitudinal end, an oppositely longitudinal end, a lateral side, and an oppositely lateral side; at least a first arm having proximal and distal ends, the at least first arm's proximal end being fixedly attached to or formed wholly with the lower chopstick; a longitudinally extending slide track fixedly attached to or formed wholly with the upper chopstick; and a pin fixedly attached to or formed wholly with the at least first arm's distal end, the pin operatively engaging the longitudinally extending slide track.
Where a pair of chopsticks is properly manually held for food handling use, the upper chopstick or the chopstick furthest from the user's body is typically grasped by the thumb, index finger, and middle finger of the user's hand. Such fingers' manipulation of the upper chopstick angularly moves the upper chopstick with respect to the lower chopstick in the manner of the jaws of food grasping pincers or tongs. Such finger actuated motion alternately increases and decreases an acute angle formed between the upper chopstick and the lower chopstick. During normal and proper chopsticks usage, other motions of the upper chopstick with respect to the lower chopstick are preferably limited and closely controlled.
During proper chopstick usage, upper and downward motions of the upper chopstick with respect to the lower chopstick are preferably closely limited. Also, during proper chopstick handling and use, rolling motions of the upper chopstick about the upper chopstick's longitudinal axis are preferably limited. Also, during such usage, longitudinal and oppositely longitudinal motions of the upper chopstick along or parallel with the longitudinal axes of the upper and lower chopsticks are preferably limited. Coordination of such limited motions of the upper chopstick with respect to the lower chopstick while executing angular motions for food grasping is often difficultly learned by a novice chopstick user.
The instant inventive training chopsticks assist and accelerate a novice chopstick user's ability to properly manually hold chopsticks by providing, among other modifications, specialized components at an arm end juncture which interconnects the chopsticks.
OBJECT AND SUMMARY OF THE INVENTIONFirst structural components of the instant inventive training chopsticks comprise a lower and an upper chopstick, each such chopstick having a longitudinal end, an oppositely longitudinal, an upper side, a lower side, a lateral side, and an oppositely lateral side. For convenience of reference, the longitudinal ends of the inventive chopsticks are considered to be the chopsticks' relatively narrow food contacting and grasping ends.
A further structural component of the instant inventive training chopsticks comprises at least a first arm having proximal and distal ends. In a preferred embodiment, the proximal end of the at least first arm is fixedly attached to or formed wholly with the lower chopstick, the at least first arm generally extending upwardly therefrom. In such embodiment, the chopsticks and the at least first arm are composed of plastic.
In a preferred embodiment, the instant inventive chopsticks comprise at least a first slide track. Where the inventive chopsticks incorporate a slide track component, the slide track is preferably fixedly attached to or formed wholly with the upper chopstick. The slide track is suitably configured as a longitudinally elongated channel which extends into and opens at the upper chopstick. The opening of the least first slide track is preferably oriented to face in a direction selected from the group consisting of downwardly, upwardly, laterally, and oppositely laterally, the opening being positioned at a corresponding chopstick side. The channel suitably comprises a through channel having oppositely facing openings at opposite sides of the upper chopstick.
In a suitable alternative embodiment, the longitudinally extending slide track component may comprise at least a first slide ridge, and, upon the selection of a ridge configuration, preferably comprises an oppositely extending pair of slide ridges. Where the slide ridge configuration of the slide track is adopted, the ridges among the pair of oppositely protruding ridges preferably extend longitudinally along opposite sides of the upper chopstick.
Further structural components of the instant inventive chopsticks comprise mounting means which are fixedly attached to or formed wholly with the at least first arm's distal end. In a suitable embodiment, the mounting means comprise at least a first pin or arm extension whose distal end extends into the channel configured slide track. Where a slide track component is incorporated, such pin may be slidably moveable there along in the longitudinal and oppositely longitudinal directions. Alternatively, where the slide track component is configured to include a longitudinally extending ridge, the mounting means component may comprise a “C” bracket formed at the distal end of the at least first arm, such bracket slidably receiving the upper chopstick's slide ridge. Where the slide track comprises the pair of oppositely protruding ridges, the mounting means may comprise a pair of “C” brackets which open toward each other for sliding receipts of such ridges.
Where the inventive chopsticks incorporate a slide track component comprising a pair of oppositely opening channels, and where such channels' inner ends do not communicate with each other, the mounting means may suitably comprise a pair of pins which oppositely extend toward each other, such pin extensions being nestingly received by the slide channels. Alternatively, where such pair of channels communicate with each other to form a through channel, the mounting means may comprise a single pin or arm extension having a length sufficient to extend through both of such communicating channels and to oppositely emerge at the opposite ends of such channel.
In a preferred embodiment, a provided slide track component comprises a channel which extends longitudinally along the upper chopstick and opens downwardly at such chopstick's lower side, such channel presenting lateral and oppositely lateral interior walls. Where the slide track component includes such interior walls, a preferred pin configuration of the mounting means may advantageously present oppositely lateral and lateral walls which correspondingly face and may engage such channel walls. Angled faces or facets of such pin's oppositely lateral and lateral walls may advantageously facilitate and limit rotary motions or yawing motions of the upper chopstick with respect to the lower chopstick. A configuration of the pin's horizontal cross-sectional shape to include a relatively wide middle section and relatively narrow longitudinal and oppositely longitudinal ends my advantageously allow such pin ends to function within the channel as rotation stops.
Similarly with the above-described horizontal cross sectional shape of the pin, the lateral cross sectional shape of the pin receiving channel may be configured to present rotation facilitating and limiting faces or facets. Where a channel configured slide track is provided, and where such track constitutes a through channel having both upper and lower openings, and where a pin configured mounting means extends through such channel, such channel may be advantageously configured to include relatively laterally wide upper and lower openings and a relatively laterally narrow middle portion. In such lateral cross section, an hourglass shape of the walls of the channel is advantageously provided. The hourglass configuration of such channel may advantageously allow limited rolling motions of the upper chopstick about its longitudinal axis.
In use of the instant inventive chopsticks, slide stopping surfaces presented at longitudinal and oppositely longitudinal ends of the preferably provided slide track or slide tracks advantageously limit longitudinal and oppositely longitudinal sliding motions of the upper chopstick with respect to the lower chopstick. Accordingly, such slide tracks and their associated slide stops may assist a novice chopstick user in proper holding and manipulation of the upper chopstick by facilitating a natural range of longitudinal and oppositely longitudinal upper chopstick motions.
Upward and downward motions and rolling motions of the upper chopstick with respect to lower chopstick may be similarly advantageously controlled at the engagement of the first arm's mounting means with the upper chopstick's channel or channel configured slide track. For example, to facilitate and limit relative upward and downward movements of the upper chopstick, lugs having slide stopping channel edge engaging surfaces may extend from the at least first pin at positions respectively overlying and underlying the upper chopstick. A small vertical displacement of such lugs, i.e. a small displacement in excess of the vertical dimension of the upper chopstick, may advantageously facilitate variability of the vertical position of the upper chopstick over the lower chopstick.
To facilitate and limit natural rolling and counter rolling motions of the upper chopstick about its longitudinal axis, the inner side walls of the upper chopstick's channel or channel configured slide track may be angled to include flared upper and lower openings.
To limit and control rotating and counter rotating motions of the upper chopstick with respect to the lower chopstick, second and third arms or a pair of rotation stopping arms may be fixedly attached to and may extend upwardly from the oppositely longitudinal end of the lower chopstick. Such arms suitably present laterally facing and oppositely laterally facing rotation stopping surfaces or lands which engage the oppositely longitudinal end of the upper chopstick. The engagements of such arms with the upper chopstick's oppositely lateral end may advantageously resist rotation of the upper chopstick and may assist with maintenance of proper chopstick alignment. Such arms may suitably alternatively extend from the upper chopstick for rotation stopping engagements with the lower chopstick.
Accordingly, objects of the instant invention include the provision of training chopsticks which incorporate structures as described above, and which arrange those structures in relation to each other in manors described above for the achievement of beneficial functions as described above.
Other and further objects, benefits, and advantages of the instant invention will become known to those skilled in the art upon review of the detailed description which follows and upon review of the appended drawings.
FIELD OF THE INVENTIONThis invention relates to food handling chopsticks. More particularly, this invention relates to such chopsticks which incorporate specialized chopstick motion modifying structures adapted for training novice chopstick users in the proper handling and use of conventional chopsticks.
Referring now to the drawings, and in particular simultaneously to
At least a first arm 30 is fixedly attached to or formed wholly with the lower chopstick 4, such arm 30 generally extending upwardly from the lower chopstick 4 toward the upper chopstick 2. Referring further to
A specialized component of the upper chopstick 2 suitably comprises a longitudinally extending channel configured slide track which is referred to generally by reference arrow 36. Referring simultaneously to
The channel configured slide track 36 of
A further structural component of the instant inventive training chopsticks comprises mounting means which are fixedly attached to or formed wholly with the at least first arm's distal end 34. The chopsticks' mounting means component necessarily operatively engages the upper chopstick 2, and where a longitudinally extending slide track such as slide track 36 is incorporated, such engagement is preferably at or in engagement with such slide track. As indicated in the embodiment of
The at least first pin 56 is suitably to extend vertically and laterally, the pin having a length sufficient for such extension to pass completely through the channel 38 or 38u, 38d. As indicated in
Relatively forward or longitudinal motion of the upper chopstick 2 with respect to the lower chopstick 4 is preferably restricted or limited by contact of the oppositely longitudinal end or edge 57 of the pin 56 with the longitudinally facing oppositely longitudinal wall 44 of the channel 38. Upon such contact, such wall face constitutes and functions as a longitudinal motion stop. Relative longitudinal motions of pin 56 within channel 38u, 38d are stopped upon contact of the longitudinal end 55 of the pin 56 with the oppositely longitudinally facing surface of the channel's longitudinal end wall 46. Accordingly, the channel end wall 46 functions as an oppositely longitudinal motion stop. In a preferred embodiment, a longitudinal elongated configuration of the channel 38, as depicted, longitudinally separates such motion stops 44 and 46, and facilitates a natural range of longitudinal motions of the upper chopstick 2 while preventing excess longitudinal motions. In a suitable, though less desired, configuration, the longitudinal dimension of channel 38 may only slightly exceed the longitudinal dimension of the pin 56, such sizing of channel 38 negating its slide track characteristic, while facilitating chopstick pivoting and rotating motions.
To limit upward and downward motions of the upper chopstick 2 with respect to the lower chopstick, downwardly and upwardly facing slide stopping surfaces 59 and 61 are suitably provided. Such stops suitably comprise faces of laterally and oppositely laterally extending lugs or protuberances 58 and 60 which are fixedly attached to or formed wholly with the pin 56. Protuberance 58 is positioned so that, upon extension of pin 56 through channel 38, the protuberance 58 overlies the upper chopstick 2 and functions as a pin extraction stop. Correspondingly, protuberance 60 is positioned so that, upon such pin extension, the protuberance underlies the upper chopstick 2 and functions as a pin insertion stop. The slide stopping surfaces 59 and 61 of protuberances 58 and 60 respectively engage the peripheral edges of lips of channel openings 42 and 40. Such channel edge engaging surfaces are preferably displaced away from each other along the length of the pin 56 a distance sufficient to provide a small travel gap 63. Such gap 63 advantageously allows a short range of natural upward and downward movements of the upper chopstick 2 away from and toward the lower chopstick 4, while facilitating natural food grasping pivoting motion of the upper chopstick. During such pivoting motions, the edges of channel openings 42 and 40 in combination with their contacts with protuberance surfaces 59 and 61 function as a rotary bearing. Accordingly, rotary bearing 40, 42, 59, 61 pivotally connects the upper chopstick 2 to the distal end of arm 30.
Referring to
To allow limited and natural rolling motions of the upper chopstick 2 about its longitudinal axis, the lateral and oppositely walls 48 and 51 of the through channel 38 or communicating channels 38u, 38d, are canted to protrude inwardly and to form an hourglass cross-sectional shape. The walls of the communicating channels 38d and 38u thereby advantageously form roll facilitating pivot edges or apexes 50 and 52. Such apexes 50 and 52 allow limited chopstick rolling motions while closely limiting lateral and oppositely lateral movements of the upper chopstick 2 with respect to pin 56. Angles “b” designated in

In use of the inventive chopsticks 1, and assuming a configuration as indicated in
Also, during the use of the chopsticks, excess longitudinal motion of the upper chopstick is stopped via contact between the channel's longitudinally facing end wall 44 and the pin's oppositely longitudinal edge 57. Correspondingly, excess oppositely longitudinal motion of the upper chopstick 2 with respect to the lower chopstick 4 is stopped by contact between the channel's oppositely longitudinally facing end wall 46 with the pin's longitudinal edge 55.
Also, during the use of the chopsticks, a natural amount of rolling motion of the upper chopstick about its longitudinal axis 2 is facilitated by the approximate 29-degree angles “b” of the faceted sections of the side walls of the slide channels 38u, 38d, such angles being defined above and below the channel's inwardly extending wall apexes 50 and 52.
Also, during use of the chopsticks, rotary or yaw motions of the upper chopstick 2 about a vertical axis and with respect to the lower chopstick 4 is similarly facilitated and limited by the pin's angled faces or surfaces 62, 64, 66, and 68.
Angular pitching and counter pitching food grasping and releasing motions of the longitudinal end 6 of the upper chopstick 2 are facilitated by the clearance gap 63 which is formed by a precisely sized vertical displacement of vertical motion stopping faces 59 and 61 of lugs 58 and 60. Such gap 63 allows relatively unrestricted rotary motion of the upper chopstick 2 about a lateral axis to facilitate grasping of food at the chopsticks' ends 6 and 10 in the manner of pincers or tongs.
