DETAILED DESCRIPTION OF THE INVENTION
[0034] Referring now to the drawings, and in particular simultaneously to
[0035] 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
[0036] 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
[0037] The channel configured slide track 36 of
[0038] 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
[0039] 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
[0040] 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.
[0041] 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.
[0042] Referring to
[0043] 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
[0044] Referring simultaneously to
[0045] In use of the inventive chopsticks 1, and assuming a configuration as indicated in
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
