Chopsticks Patents (Class 294/218)
  • Patent number: 11246436
    Abstract: Training chopsticks are designed to guide beginners and lifelong users alike to adopt a proper chopstick grip, allowing learners to extend chopstick tips wide apart. They allow learners to focus first on mastering the twirling of chopsticks between the closed posture to the wide-open posture, based on principles of the planetary gear train, without having to simultaneously learn to secure chopsticks using the required thumb pose. Such thumb pose can be mastered later as a second step. Furthermore, a variation of training chopsticks provides an elevated thumb rest to accommodate learners suffering from anatomical limitations. As a result, a learner can wield these training chopsticks to embrace large food items with ease, manipulate these large items with dexterity and finesse in the same way she can small items, and generate enough compression force to hold all items firmly between training chopsticks.

  • Patent number: 10104996
    Abstract: A pair of chopsticks is disclosed, each of which includes a first body, a second body, and a locking member. The first body has at least one positioning slot, a storage space, and an opening communicating with the storage space. The second body can be completely or partly received in the storage space through the opening of the first body, wherein an outer wall of the second body has at least one protrusion which enters the positioning slot when the second body is in a predetermined position in the storage space. The locking member has a locking portion engaged with the first body, wherein the locking member is controllable to make the locking portion enter the positioning slot to prevent the protrusion therein from leaving the positioning slot whereby the chopsticks are retractable and more portable.

  • Patent number: 9004566
    Abstract: A pair of chopsticks that may be reversibly attached in a cooperating manner for providing a forceps- or tweezers-like spring action for grasping objects, such as food, or for being used in the conventional manner for using chopsticks, is described. Identical angled channels located in the vicinity of the non-grasping end of each chopstick and having a depth of about one-half the width of the chopstick, permit the opposing channels to be fitted together to join the chopsticks. A retaining member may be wrapped around the channel joint to stabilize the joint and hold the chopsticks together. In another embodiment, two shallow angled side indentations are cut into the width of each chopstick at diagonally opposing sides of the primary angled channel formed therein, creating compression surfaces which oppose rotation and opening of the channel joint.

  • Patent number: 8333418
    Abstract: An implement (800) for use in the consumption of food includes a pair of elongate members (820, 822) having a first end for contacting the food and a second end for applying a pressure to operate the implement. The elongate members are pivotable with respect to each other. The implement is urged to a storing position in which the first ends of the elongate members are in close proximity to each other and the second ends are spaced apart so that as pressure is applied to the second ends of the elongate members (820, 822) the elongate members pivot with respect to each other separating the first ends and enabling food to be located there between. When the pressure is released the food is gripped by the first ends of the elongate members and can be lifted.
