Description

{Chopsticks For The Nonexpert}

The present invention relates to a chopstick, and more particularly, to an unskilled chopstick that can be easily used by an unskilled person and can be used for practice.

Chopsticks are widely used tools in the Orient and consist of two thin rods. For those who use chopsticks for the first time, such as Westerners or infants, it is not easy to use chopsticks skillfully. It is not uncommon to learn how to use chopsticks properly. To cope with such problems, a chopstick aiding device has been widely proposed to make it easy to learn how to use chopsticks.

These chopstick aids are popular for infants, but they are also useful for adults who have not grown up in chopstick culture or adults who want to learn how to use the right chopsticks.

Conventional chopstick aids have a mechanical principle in which two linear rods are rotated about one point and the ends are folded together. In addition, two linear bars are connected in a hinge form in various ways.

The chopsticks must be hygienically safe and easy to use because of their simple weight and structure. Also, when using chopsticks, there is no inconvenience to use because there is little frictional resistance. However, it is difficult to find a chopstick aiding device that meets all these requirements.

For example, the chopstick assisting apparatus of Korean Utility Model Registration Application No. 20-2008-0002989 has a complicated structure, and since Korean Patent Application No. 10-2001-0048508 has a unique cross-sectional shape, it is difficult to manufacture, There is a problem that it is difficult to adjust easily because it is different from chopsticks.

The second fitting ring 11 is fitted to the second rod S2, which is the other one of the bars, and is fixed by frictional force. The fixing table 30 is connected to the second shim 11 so as to be in surface contact with both surfaces of the rotary plate 20 and provides a fitting space of a U-shaped configuration (see Fig. 4). The fixing table 30 includes a pair of fixing plates 30a and 30b facing each other. The fixing plates 30a and 30b are in a disc shape. The fitting space in the fixing table 30 is preferably provided with an inner circumferential surface 33 having the same diameter as the outer circumferential surface 23 of the rotary plate 20 (see FIGS. This eliminates clearance so that there is no shaking during use.

The first and second fitting rings 10 and 11 are fitted to the rear side of the chopstick body S, that is, the coarse side, so as to have a rotation center similar to a general chopstick.

The rotary plate 20 is sandwiched between the fixing plates 30a and 30b constituting the fixing table 30 so that the rotary plate 20 and the fixing table 30 are coupled with each other in this state to rotate relatively do. That is, the hinge connection means are various means provided on the rotary plate 20 and the fixing table 30 so as to relatively rotate with respect to the rotation center point on the rotary plate 20 in a state where the rotary plate 20 is fitted in the fixing table 30 .

On the other hand, rotation limiting means for limiting the degree of rotation of the rotary plate 20 and the fixing table 30 is provided. The rotation restricting means includes locking protrusions 21 and 22 protruding from both sides of the rotary plate 20 and locking protrusions 31 and 32 provided on the fixing table 30. The locking projections 21 and 22 are provided on both sides of the rotation center 20 with respect to the rotation center point thereof. It is preferable that the engaging projections 21 and 22 are provided on both sides of the rotary plate 20. Therefore, the number of the locking protrusions 21 and 22 is four in total.

The engaging jaws 31 and 32 are provided on both sides of the fixing table 30, respectively. The engaging protrusions 31 and 32 are engaged with the engaging projections 21 and 22 so that the rotating plate 20 can no longer be rotated in the same direction. As shown in FIG. 3, each of the engaging jaws 31 and 32 is provided with a U-shaped guide groove on both sides of the fixing table 30. The guide groove is in the form of an arc, and the rotation plate 20 is guided to rotate within the fixing table 30 without shaking.

According to such a configuration, the rotary plate 20 will be rotated in both directions as if it is seated on the basis of the rotation center point in a state in which the rotary plate 20 is closely fitted to the fixing table 30. The right and left heights of the locking protrusions 21 and 22 and the right and left heights of the corresponding locking protrusions 31 and 32 will be appropriately selected in consideration of the degree of rotation.

The hinge connecting means described above may be of various shapes, two of which are exemplified herein. First, the first embodiment will be described with reference to Figs. 2 to 5. Fig.

A center shaft 34 that can be fitted into the center hole 24 projects from the inner surfaces of the fixing plates 30a and 30b of the fixing table 30. And the rotary plate 20 is sandwiched between the fixing plates 30a and 30b so that the center shafts 34 can be fitted into the center holes 24. In this case, The fixing plates 30a and 30b have a certain strength and elasticity as a synthetic resin and can be slightly opened. When the external force is removed, the fixing plates 30a and 30b return to their original state. According to the present embodiment, the rotary plate 20 and the fixing table 30 can be rotated as a seesaw motion with the center shaft 34 as a rotation center point by being coupled to each other without any auxiliary tool. 6 (a), 6 (b) and 6 (c) are front views of the state of use, in which the latching protrusions 21 and 22 are engaged with the latching jaws 31 and 32, respectively, (Fig. 6 (b)) and its intermediate state (Fig. 6 (a)). The position where the first and second fitting rings 10 and 11 and the third fitting ring 12 described later are installed in the respective bars S1 and S2 and the size of each part, specifically, It should be decided based on usage.

Hereinafter, a second example of the hinge connecting means will be described with reference to Fig.

A center hole 24 is provided at a rotation center point of the rotary plate 20. The fixing table 30 is provided with an outer hole 36 at the same position as the center hole 24. [ And the pin connecting port 50 fixes both the rotating plate 20 and the fixing base 30. [ The pin connector (50) includes a decorative plate (51) and a center pin (52).

The center pin 52 is inserted into the outer hole 36 at the same time. A decorative plate (51) is integrally attached to one side of the center pin (52), and a slip prevention means is provided on the other side.

The center pin 52 is inserted into the outer hole 36 so that the end surface of the end portion 54 is widened in a dovetail shape so that it can be prevented from falling out. A groove 53 may be provided at the end of the center pin 52 to prevent it from coming out more surely by inserting a binding means such as a snap ring (not shown) into the groove 53.

The back side 51a of the decorative plate 51 may be provided with a sticker or a coating or printing to improve the intimacy with the infant.
