Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of chopsticks, and in particular to a pair of practice chopsticks. Background Art

[0002] Chopsticks are the most commonly used dining utensil in China. Compared with forks and knives, they are more difficult to use, especially for children. It takes some time for them to gradually learn to use chopsticks. Using practice chopsticks can more conveniently teach children how to use chopsticks.

[0003] Current practice chopsticks consist of two chopsticks and a connector 3 hingedly connected to the two chopsticks. The connector 3 connects the two chopsticks together and is used to keep the tips of the two chopsticks aligned. During practice, the two chopsticks rotate around the hinge or sliding portion to pick up food, practicing the opening and closing of the chopsticks.

[0004] like Figure 1 As shown, the most commonly used practice chopsticks currently have hinges at the tops of the first chopstick 1 and the second chopstick 2, so that the tips of the chopsticks can always remain aligned, and different sizes of food can be picked up by opening the two chopsticks at different angles.

[0005] like Figure 2 As shown, in the practice chopsticks with authorization announcement number CN201831541U, the upper parts of the first chopsticks 1 and the second chopsticks 2 are hinged by a hinge, and the tops of the two chopsticks are connected by a thin spring. The two chopsticks rotate around the two sides of the hinge respectively, and the tips of the two chopsticks can always be aligned to practice opening and clamping the chopsticks.

[0006] However, in this case, the two chopsticks always maintain a constant distance at the hinge and cannot move laterally at the hinge. As we know, during normal use, chopsticks are flexible and can move laterally at various points to facilitate picking up food of varying sizes. With long-term use, the hand will automatically pick up food at the most appropriate angle and with minimal force. However, these chopsticks do not move laterally at the hinge or at its upper and lower sides. While children can pick up food with training chopsticks, they cannot do so at the most appropriate angle and with minimal force. Without the connector 3, the tips of the chopsticks are difficult to maintain accurate alignment, making it difficult for children to effectively practice with the training chopsticks. Therefore, this shortcoming is currently difficult to overcome.

[0007] like Figure 3As shown, in order to address this problem, in the practice chopsticks with the authorization announcement number CN208725407U, the first chopsticks 1 and the second chopsticks 2 are connected to the chopsticks in a relative sliding manner. The chopsticks are opened with a hole, and the connecting member 3 passes through the hole and is connected to the chopsticks. The chopsticks on one side are fixed by the elasticity of the connecting member 3, and the chopsticks on the other side can slide on the connecting member 3, so that the lateral position of the two chopsticks at the top changes. In order to ensure that the chopsticks can rotate normally, the sliding part of the connecting member 3 must be ensured to be oblique to the chopsticks. However, if the chopsticks slide on the connecting member 3 during use, it is difficult to ensure that the tips of the chopsticks are aligned, which goes against the original intention of the design. It can only slide during installation. Therefore, it is difficult for the two chopsticks to move laterally at the position of the connecting member 3 during use. This shortcoming is still difficult to overcome for this application.

[0008] We noticed that when using two chopsticks, one chopstick is clamped between the inner side of the thumb and index finger, and the other chopstick is clamped between the outer side of the thumb and index finger. The chopstick on the inner side does not move, but only rotates around the clamping part of the finger. The other chopstick can move laterally at the clamping part of the finger and rotate around the clamping part of the finger. Based on this characteristic of using chopsticks, how to design a pair of chopsticks that can move laterally at the position of the connecting part 3 according to the force of the fingers and can rotate around the connecting part 3 at the same time, so as to clamp food at the most appropriate angle and with the least force to achieve the best practice effect, is a problem that needs to be solved. Summary of the Invention

[0009] To this end, an embodiment of the present invention provides a pair of practice chopsticks to solve the problem in the prior art that the best practice effect cannot be achieved because the chopsticks cannot move laterally at the position of the connecting piece.

[0010] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0011] A pair of practice chopsticks, comprising a first pair of chopsticks, a second pair of chopsticks, and a connecting member, wherein a first connecting groove is formed on a side wall of the first pair of chopsticks near the head, and a second connecting groove is formed on a side wall of the second pair of chopsticks near the head, and both the first connecting groove and the second connecting groove are through holes; the connecting member is elastic, and comprises a first folding portion, a second folding portion, a first inwardly concave rod, a second inwardly concave rod, and a crescent portion; the connecting groove of the second pair of chopsticks is hingedly connected to the crescent portion, the first folding portion and the first inwardly concave rod are located at the upper portion, and the second folding portion and the second inwardly concave rod are located at the lower portion;

[0012] One end of the first folding portion is fixedly connected to one end of the first inwardly concave rod, and the other end is folded upward in an arc shape onto the side wall of the first inwardly concave rod; one end of the second folding portion is fixedly connected to one end of the second inwardly concave rod, and the other end is folded downward in an arc shape onto the side wall of the second inwardly concave rod, and the distance between the two ends of the first folding portion and the second folding portion away from the first inwardly concave rod is greater than or equal to the width of the first connecting groove and the second connecting groove;

[0013] The first concave rod is concave downward in an arc shape, and the second concave rod is concave upward in an arc shape, and the distance between the two gradually shortens from the end to the middle. A sliding groove is formed on the outer side of the first concave rod and the second concave rod, and the width of the sliding groove at the widest point is smaller than the width of the first connecting groove and the second connecting groove; the crescent portion is connected to the first concave rod and the second concave rod.

[0014] Furthermore, the crescent portion includes a first arc-shaped rod, a second arc-shaped rod, a first support rod and a second support rod; one end of the first arc-shaped rod is fixedly connected to one end of the first concave rod, and the other end is fixedly connected to one end of the second arc-shaped rod, the first arc-shaped rod and the second arc-shaped rod are symmetrically arranged at their junction, the first arc-shaped rod and the second arc-shaped rod are both arc-shaped with the middle convex upward and the two sides concave downward, the first arc-shaped rod and the second arc-shaped rod are crescent-shaped as a whole, and the junction of the two forms a concave arc-shaped mounting groove, and the first chopsticks are hinged to the mounting groove through the first connecting groove;

[0015] One end of the first support rod is fixedly connected to the second arc-shaped rod, and the other end is fixedly connected to the second support rod. The first support rod protrudes to the side away from the second arc-shaped rod to form an arc. The second support rod is horizontally arranged and one end of it is fixedly connected to the first support rod, and the other end is fixedly connected to the second concave rod.

[0016] Furthermore, the distance between the two ends of the first concave rod and the second concave rod close to the crescent portion is 6 mm.

[0017] Furthermore, an access port is formed between the first folded portion and the second folded portion, and the outermost length of the access port is 13 mm.

[0018] Furthermore, the total length of the first arc-shaped rod and the second arc-shaped rod in the horizontal direction is 13 mm.

[0019] Furthermore, the vertical length of the highest points of the second support rod and the second arc-shaped rod is 13 mm.

[0020] Furthermore, the lower portion of the first connecting groove is horizontal and the upper portion is inclined. The length of the opening on one side of the first connecting groove is 11 mm, and the length of the opening on the other side is 13 mm.

[0021] Furthermore, the upper portion of the second connecting groove is horizontal and the lower portion is inclined. The opening length of one side of the second connecting groove is 10.5 mm, and the opening length of the other side is 12 mm.

[0022] Furthermore, one end of the first folding portion away from the first concave rod is folded upward in an arc shape onto the side wall of the first folding portion, and one end of the second folding portion away from the second concave rod is folded downward in an arc shape onto the side wall of the second folding portion, and the folding points of the first folding portion and the second folding portion both form folding portions.

[0023] Furthermore, the cross-sectional diameter of the connecting piece is 1.2 mm, the width of the first connecting groove is 1.6 mm, and the width of the second connecting groove is 1.2 mm.

[0024] The embodiments of the present invention have the following advantages:

[0025] When practicing using chopsticks, the fingers will first move the first chopstick to slide on the chute. Depending on the size of the food, the position of the first chopstick sliding on the chute is also different. When the food is small, the first chopstick and the second chopstick are closer together. When the food is large, the first chopstick and the second chopstick are farther apart. When the first chopstick is in different positions, because the chute is in a horizontal state, the width of the first connecting groove is greater than the width of the chute, and the tips of the first chopstick and the second chopstick can remain aligned. And because the chute is wide at both ends and narrow in the middle, the first chopstick is more labor-saving when sliding on the chute. When finding the best position, the first and second chopsticks are opened to pick up the food. At this time, the fingers will automatically adjust the angle of the first and second chopsticks so that the first and second chopsticks can pick up the food with minimal force. After using the food, the fingers will move the first chopstick to the initial finger grip position for the next gripping practice, thereby achieving the best training effect. Because the width of the second connecting groove is greater than the width of the first connecting groove, the second chopstick is more labor-saving to rotate, which is more convenient when practicing.

DETAILED DESCRIPTION

[0036] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0037] A kind of practice chopsticks, such as Figure 4 and Figure 5 As shown, it includes a first chopstick 1, a second chopstick 2 and a connecting piece 3. The first chopstick 1 and the second chopstick 2 are both cylindrical, and the ends of the two that hold food are retracted inward to form a tapered tip, which is located at the bottom; the ends of the first chopstick 1 and the second chopstick 2 away from the tip are their heads, which are located at the top.

[0038] The sidewall of the first chopstick 1 near the head is provided with a first connecting groove 11 with a rectangular cross-section, and the sidewall of the second chopstick 2 near the head is provided with a second connecting groove 21 with a rectangular cross-section. The lower portions of the first connecting groove 11 and the second connecting groove 21 are both horizontally arranged and the upper portions are both inclined. The upper and lower sides of the first connecting groove 11 and the second connecting groove 21 are both convex semicircular. The first connecting groove 11 and the second connecting groove 21 are both through holes. The opening length of the first connecting groove 11 on one side is 11 mm and the opening length of the other side is 13 mm; the opening length of the second connecting groove 21 on one side is 10.5 mm and the opening length of the other side is 12 mm. The connecting member 3 is preferably a steel wire with a diameter of 1.2 mm. The width of the first connecting groove 11 is 1.6 mm, and the width of the second connecting groove 21 is 1.2 mm. The first connecting groove 11 is relatively wide to ensure that the first chopstick 1 slides more smoothly on the connecting member 3, while the second connecting groove 21 is relatively narrow to prevent it from shaking on the connecting member 3.

[0039] like Figure 6 As shown, the connecting member 3 is elastic as a whole and includes a first folding portion 31, a first concave rod 32, a first curved rod 33, and a second curved rod 34 at the upper portion, and a second folding portion 35, a second concave rod 36, a first support rod 37, and a second support rod 38 at the lower portion. The first folding portion 31, the first concave rod 32, the first curved rod 33, the second curved rod 34, the first support rod 37, the second support rod 38, the second concave rod 36, and the second folding portion 35 are arranged in sequence.

[0040] One end of the first folded portion 31 is fixedly connected to one end of the first inwardly concave rod 32, and the other end is folded upward in an arc shape onto the side wall of the first inwardly concave rod 32. One end of the second folded portion 35 is fixedly connected to one end of the second inwardly concave rod 36, and the other end is folded downward in an arc shape onto the side wall of the second inwardly concave rod 36. An access port 311 is formed between the first and second folded portions 31 and 35. The outermost length of the access port 311 is 13 mm. The first inwardly concave rod 32 is recessed downward in an arc shape, while the second inwardly concave rod 36 is recessed upward in an arc shape. The distance between the ends of the first and second inwardly concave rods 32 and 36 near the first support rod 37 is 6 mm, and the distance between the two ends gradually decreases from the ends to the middle. A sliding groove 321 is formed on the outer sides of the first and second inwardly concave rods 32 and 36. The folding diameter of the first folding portion 31 is 4 mm, and the folding diameter of the second folding portion 35 is 4 mm. The outer surfaces of the first folding portion 31 and the second folding portion 35 are relatively smooth, which can prevent children from getting hurt when practicing with chopsticks.

[0041] One end of the first arc rod 33 is fixedly connected to one end of the first concave rod 32, and the other end is fixedly connected to one end of the second arc rod 34. The first arc rod 33 and the second arc rod 34 are symmetrically arranged at the connection between the two. The first arc rod 33 and the second arc rod 34 are both arc-shaped with the middle convex upward and the two sides concave downward. The first arc rod 33 and the second arc rod 34 are crescent-shaped as a whole, and the connection between the two forms a concave arc-shaped installation groove 331.

[0042] One end of the first support rod 37 is fixedly connected to the second curved rod 34, and the other end is fixedly connected to the second support rod 38. The first support rod 37 protrudes toward the side away from the second curved rod 34, forming an arc. The second support rod 38 is arranged horizontally and has one end fixedly connected to the first support rod 37 and the other end fixedly connected to the second concave rod 36. The total horizontal length of the first curved rod 33 and the second curved rod 34 is 13 mm, and the vertical length of the second support rod 38 and the highest point of the second curved rod 34 is 13 mm.

[0043] When installing the connector 3, the first folding portion 31 and the second folding portion 35 are squeezed to bring them closer to each other, and then the second chopstick 2 is inserted first. The second chopstick 2 passes through the access port 311 and the first concave rod 32 to slide onto the slide groove 321. Then, the first curved rod 33 and the second curved rod 34 are squeezed to shorten the distance between the second curved rod 34 and the second support rod 38, and the second chopstick 2 slides into the installation groove 331 to achieve hinged connection. The first folding portion 31 and the second folding portion 35 are squeezed again, and the first chopstick 1 passes through the access port 311 and the first concave rod 32 and slides onto the slide groove 321. The first folding portion 31 and the second folding portion 35 can prevent the first chopstick 1 located on the slide groove 321 from sliding out. Since the width of the first connecting groove 11 in the first chopstick 1 is greater than the width of the slide groove 321, the first chopstick 1 can slide and fold at any position on the slide groove 321. Since the installation groove 331 is a concave arc surface, the second chopstick 2 can fold around the installation groove 331.

[0044] like Figure 7 As shown in Figures 7-1, 7-2, and 7-3, when practicing using chopsticks, the fingers will first move the first chopstick 1 to slide on the slide groove 321. Depending on the size of the food, the position of the first chopstick 1 sliding on the slide groove 321 is also different. When the food is small, the distance between the first chopstick 1 and the second chopstick 2 is closer. When the food is large, the distance between the first chopstick 1 and the second chopstick 2 is farther. When the first chopstick 1 is in different positions, since the slide groove 321 is in a horizontal state, the width of the first connecting groove 11 is greater than the width of the slide groove 321, and the tips of the first chopstick 1 and the second chopstick 2 can be kept aligned. Moreover, since the slide groove 321 is wide at both ends and narrow in the middle, the first chopstick 1 is more labor-saving when sliding on the slide groove 321. When the optimal position is found, the first chopsticks 1 and the second chopsticks 2 are opened to pick up food. At this time, the fingers will automatically adjust the angles of the first chopsticks 1 and the second chopsticks 2 so that the first chopsticks 1 and the second chopsticks 2 can pick up food with minimal force. After using the food, the fingers will move the first chopsticks 1 to the initial finger grip position to practice the next grip, thereby achieving the best training effect. Since the width of the second connecting groove 21 is greater than the width of the first connecting groove 11, the second chopsticks 2 are more labor-saving to rotate, which is more convenient during practice.

[0045] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
