And, as shown in FIG. 16 , all of the four protruding bands 12a , 12b , 22a , and 22b are positioned at the same distance from the central axis of the first cylinder 11 , respectively.

By doing this, as shown in FIG. 3, when the first and second bodies 100 and 200 are coupled and the inner surfaces of the two object handling parts 18 and 28 are attached to each other, as shown in FIGS. 8 and 9 As described above, the upper protruding band 12a of the left connecting part and the upper protruding band 22a of the right connecting part may overlap each other at the front and rear of the same upper position of the first cylinder 11 . At this time, at the same time, the lower protruding band 12b of the left connecting part and the lower protruding band 22b of the right connecting part may overlap each other in front and behind the same lower position of the first cylinder 11 .

In addition, as shown in FIGS. 7 and 9, in order to increase the bonding strength between the two connecting parts 10R and 20R and minimize the gap, the 4a cylinder 13 of the left connection part and the 4b cylinder 23 of the right connection part Silver, it is preferable to configure at the same height as each other so that the rear plate 14 of the left connection part and the front plate 24 of the right connection part can come into contact with each other at the midline 1424 of the front and rear plates.

Here, together with a method for more easily coupling or separating the first and second bodies 100 and 200, the rotational operation function and the leveling function of the two coupled connecting parts 10R and 20R are more stably implemented. An effective configuration will be described as follows.

As shown in FIGS. 3 and 10 and 13 , the upper protruding band 12a and the lower protruding band 12b of the left connecting part are configured to be symmetrical with each other on the left and right handle center line W. As shown in FIG.

In addition, the upper protruding band 22a and the lower protruding band 22b of the right connection part are also configured to be symmetrical with each other on the left and right handle center line (W). In addition, it is preferable that all of the four protruding bands have a length of about 1/4.1 to 1/5 of the circumference, respectively.

By doing this, the two bodies in the coupled state after assembly as shown in FIG. 3 (or FIG. 8) are rotated at an angle of about 90 degrees to each other as shown in FIG. 16 , the first body 100 and the second body 200 are rotated. When , it has the following state.

As shown in FIG. 19 , the second cylinder 22 and the two protruding bands 22a and 22b of the right connection part are located in the empty space 12h inside the third cylinder 12 of the left connection part.

Here, the meaning and purpose of the 'object handling unit' used to describe the present invention will be described in detail as follows.

The term 'object' refers to a substance in a solid or liquid state, not a gas.

'Handling', as the name of the present invention refers to as 'claw-type tool', does not mean only a pinching action, but refers to a process handled in various ways according to the state of the object and the intention of the tool user.

Therefore, the 'object handling unit' aims to handle objects in various states and shapes according to the user's intention, and can be of various structures and shapes or of various sizes and weights at the position under the finger hanger. , it is not limited to the chopstick shape drawn in the drawings for explaining the present invention. For example, it may be configured in the form of a spoon, and two object handling units may be combined to form a single spoon.

In consideration of the characteristics of the object handling unit, a state in which the object handling unit is floating in the air when the tool according to the present invention is placed on the floor (hereinafter referred to as 'elevating state') will be described as follows. For example, as shown in FIG. 21 , it may have a configuration in which the handle-side section (Pb) is heavier than the object handling section (Pa) with respect to the fulcrum (P). Therefore, since the elevating state is made, it is possible only by adjusting the material and size of the two sections (Pa, Pb).

However, in order to more effectively achieve the elevating state while minimizing the level of adjustment of material and size, as shown in FIGS. 8 and 9, weight control for accommodating the filling material for weight adjustment in the center space of the first cylinder 11 It is also possible to constitute the part S.

Here, the main functions of the four protruding bands 12a, 12b, 22a, 22b will be described as follows. The four protruding bands 12a, 12b, 22a, 22b have a function of maintaining a strong binding force so that there is no shaking during the rotating operation of the two bodies, and the two object handling parts 18 and 28 do not shift during the object handling process. It has the function to keep it level to avoid it.

A configuration for more efficiently forming the four protruding bands to have such a function is as follows. First, as shown in FIG. 12 , on the rear plate 14 of the left connection part, the rear surfaces of the two protruding bands 12a and 12b formed on the inner surface of the third cylinder 12 can be seen through two Four through holes 12ah and 12bh are formed. In addition, as shown in FIG. 15, the front plate 24 of the right connection part has two protruding bands 22a and 22b formed on the outer surface of the second cylinder 22 through which the front surfaces can be seen through. Through-holes 22ah and 22bh are formed. Accordingly, the molding can be achieved simply.

This configuration is a problem that can be predicted by a person of ordinary skill in the art - that is, the four protruding bands 12a, 12b, 22a, 22b in the absence of the four through holes 12ah, 12bh, 22ah, 22bh. It is desirable in that it can eliminate inefficiencies and instability that occur during molding, and at the same time provides a structure and conditions for forming four protruding bands more efficiently, firmly and precisely.

And, the four through-holes can be easily concealed using the cover (C) as shown in FIG. Therefore, the method for forming the four protruding strips falls within the scope of the present invention regardless of whether the four through holes are exposed.

The tongs-type tool according to the present invention may be provided with a finger hanger together with a handle as being used for the operation of a finger.

Therefore, the following describes the finger rests (15, 25).

As shown in FIGS. 1, 2 and 5 , the finger rests may be symmetrically provided on the side surfaces of the two handle parts 10 and 20 .

At this time, as illustrated in FIGS. 22 and 23 , the index finger insertion holes 16 and 26 for inserting or draping the tip of the index finger of the right or left hand from the outer surface of the handle part to the inner surface direction may be formed.

Here, the index finger inserts 16 and 26 formed in the two finger hangers are penetrated from the upper outer surface of the handle part to the lower inner surface for natural entry and exit of the fingers, and the outer surfaces of the index finger inserts 16 and 26 It is preferable that the upper part be inclined toward the upper end of the handle and be concave at the same time, and the lower part of the inner surface of the index finger inserts 16 and 26 should be inclined toward the object handling part and be concave at the same time.

In addition, as shown in FIGS. 3 and 4, an arcuate long space 30 is formed between the two handle portions 10 and 20, so that a part of the hand is held between the two handle portions in the process of holding and using the handle. It is desirable to prevent it from falling off and at the same time make it easy to hang on a general tool hanger.

In this case, the 1-1 protrusion 332 and the 1-2 protrusion 334 may be positioned at opposite positions with the first pipe 314 interposed therebetween. For example, when the first stick 300 is erected, the 1-1 protrusion 332 is located on the upper portion of the first pipe 314 , and the 1-2 protrusion 334 is the first pipe 314 . It may be located at the bottom.

In this case, the 2-1 protrusion 432 and the 2-2 protrusion 434 may be positioned opposite to each other. For example, when the second stick 400 is erected, the 2-1 protrusion 432 is positioned on the upper portion of the second pipe 412 , and the 2-2 protrusion 434 is the second pipe 412 . It may be located at the bottom. Therefore, in the light of <Explanation 1>, the 2-1 protrusion 432 corresponds to the upper protruding band 22a of the right connecting part, and the 2-2 protrusion 334 corresponds to the lower protruding band 22b of the right connecting part. It can be said that the composition

In addition, the 2-1 protrusion 432 and the 2-2 protrusion 434 may be formed by a predetermined arc angle range. According to an embodiment, the arc angle range θ3 of the 1-1 protrusion 332 and the arc angle range θ4 of the 1-2 protrusion 334 shown in FIG. 31 may be 60° to 80°, respectively. . In addition, in view of <Description 1>, the circumferential range of the 2-1 protrusion 432 and the 1-2 protrusion 434 may be about 1/4.1 to 1/6 of the circumference, respectively. For example, the arc angle range of the 2-1 protrusion 432 and the arc angle range of the 2-2 protrusion 434 are 72°. In the circumferential direction of the 2 pipe 412, between the 2-1 protrusion 432 and the 2-2 protrusion 434 (left and right of the second pipe 412), each space having an arc angle range of 108° ( A 2-2 space (W2) to be described later) is formed.

In this state, when the angle between the first stick 300 and the second stick 400 varies, the first pipe 314 and the second pipe 412 about the central axes C1 and C2. rotates relative. Accordingly, the first protrusion 330 and the second protrusion 430 also rotate relative to the central axes C1 and C2. According to the relative rotation, at least a portion of the first protrusion 330 and the second protrusion 430 overlaps each other in the front-rear direction or does not overlap in the front-rear direction.

At this time, when the first protrusion 330 and the second protrusion 430 overlap in the front-rear direction, the first stick 300 and the second stick 400 are not separated from each other. This is because the first protrusion 330 and the second protrusion 430 are engaged with each other in the front-rear direction. Accordingly, the first stick 300 and the second stick 400 maintain a connected state to each other.

Conversely, when the first protrusion 330 and the second protrusion 430 do not overlap in the front-rear direction, the front-to-rear engagement between the first protrusion 330 and the second protrusion 430 is released. Accordingly, the first rotation connection part 300R and the second rotation connection part 400R may be separated from each other.

For example, when the first stick 300 and the second stick 400 have a separation angle (eg, 90°) that is an angle between each other of a predetermined size, the first protrusion 330 and the second protrusion 430 are ) may be located at a position where they do not overlap each other in the front and rear directions. Accordingly, the first stick 300 and the second stick 400 may be separated from each other in the front and rear directions.

In addition, when the first stick 300 and the second stick 400 have an angle between each other equal to or less than the separation angle, the first protrusion 330 and the second protrusion 430 move forward and backward with each other. It may be located in an overlapping position. Accordingly, the connection between the first stick 300 and the second stick 400 may be maintained.

Also, FIGS. 35 and 36 are views showing the connection between the first stick 300 and the second stick 400 . 37 is a diagram illustrating a state when the first stick 300 and the second stick 400 have the separation angle K from each other. The connection between the first stick 300 and the second stick 400 is performed with the first rotational connection part 300R and the second stick 400 in a state where the first stick 300 and the second stick 400 have a separation angle K from each other. This is achieved by connecting the two rotational connection parts 400R to each other. That is, the connection between the first stick 300 and the second stick 400 may be performed in the reverse order of the separation of the first stick 300 and the second stick 400 .

However, it is obvious that the same embodiment may be implemented even using the terminology of Description 1. As a simple example, in the following description, it has been described that the first slope part 340 is provided at the upper end of the first stick 300 , but when the terms of the first description are used, the first slope part 340 is the first It may be described as being formed on the upper end of the body 100 .

In the following description, the description as if the configuration described in Description 3 was additionally applied to the embodiment described in Description 2 is made, but the description is not necessarily limited thereto.

38 shows the first slope part 340 and the second slope part 440 in a state where the first grip part 32 and the second grip part 42 of the first stick 300 and the second stick 400 are in contact with each other. 39 is a view showing a state in which the first slope part 340 and the second slope part 440 are in contact with each other when the first stick 300 and the second stick 400 have a separation angle from each other. to be. 40 to 43 are views sequentially illustrating that the first stick 300 and the second stick 400 are separated from each other by the first slope part 340 and the second slope part 440 .

First, an embodiment in which the first slope unit 340 is provided at the upper end of the first stick 300 and the second slope unit 440 is provided at the upper end of the second stick 400 will be described.

The first slope part 340 and the second slope part 440 are positioned to face each other when the first stick 300 and the second stick 400 have the separation angle.

The direction of the first slope part 340 has a direction to be spaced apart from the bottom part 310 (ie, toward the front) from left to right. In addition, the direction of the second slope part 440 has a direction that is spaced apart from the front part 410 (ie, toward the rear) from right to left.

The inclination angle of each of the first and second slope portions 340 and 440 is not limited, but may be 30 to 60° according to an example. In addition, roundings R1 and R2 may be formed at the ends of each of the slopes 340 and 440 .

The first and second slope portions 340 and 440 are formed with the first stick 300 and It is a component that induces the second stick 400 to be separated naturally.

In this case, the first protrusion 330 and the second protrusion 430 may have rounded or inclined surfaces (eg, 330a and 430a shown in FIG. 41 ) at their ends. Also, as described above, the first protrusion 330 and the second protrusion 430 may have an arc angle within a predetermined range. In addition, although not shown, in a state where the angle between the first stick 300 and the second stick 400 becomes the separation angle, the first protrusion 330 and the second protrusion 430 move in the front-rear direction. They may not overlap each other.

Accordingly, when the first stick 300 and the second stick 400 are separated from each other because the angle between the first stick 300 and the second stick 400 is greater than the separation angle, the first protrusion 330 is and the second protrusion 430 may or may not collide with each other. For example, as described above, the 1-1 protrusion 332 , the 1-2 protrusion 334 , and the 2-1 protrusion 432 constituting the second protrusion 430 constituting the first protrusion 330 . ), the 2-2 protrusion 434 may have a predetermined length (a length of about 1/4.1 to 1/6 of a circumference) or a predetermined arc angle range (60° to 80°). Accordingly, when the first stick 300 and the second stick 400 are diagonally separated by the first and second slope portions 340 and 440 , the first protrusion 330 and the second protrusion 430 . may or may not collide with each other.

Hereinafter, the separation of the first stick 300 and the second stick 400 by the first slope part 340 and the second slope part 440 will be described in detail.

First, a state in which the first stick 300 and the second stick 400 are connected to each other is shown in FIG. 40 . 40 shows the first rotational connection part 300R when the first stick 300 and the second stick 400 are connected to each other and the first grip part 32 and the second grip part 42 are in contact with each other, and The second rotation connection part 400R of the second stick 400 is shown. At this time, (a) to (c) of FIG. 40 is a first rotational connection part 300R of the first stick 300, a second rotational connection part 400R of the second stick 400, and a first rotational connection part ( The positions of the first protrusion 330 of 300R and the second protrusion 430 of the second rotation connection part 400R are shown. (In the drawings after FIG. 40, some components are omitted for convenience of confirmation.) As shown in FIG. 40 (c), the first stick 300 and the second stick 400 are connected to each other, and the first When the grip part 32 and the second grip part 42 are in contact with each other, the first protrusion 330 and the second protrusion 430 overlap in the front-rear direction. Of course, even when the angle between the first stick 300 and the second stick 400 is in the range less than or equal to the separation angle, at least one portion of the first protrusion 330 and the second protrusion 430 may overlap in the front-rear direction. will be.

41 shows the first rotation when the angle between the first stick 300 and the second stick 400 is widened so that the first stick 300 and the second stick 400 have a separation angle from each other. The connection part 300R and the second rotation connection part 400R of the second stick 400 are shown. As described above, when the first stick 300 and the second stick 400 have a separation angle from each other, the first protrusion 330 and the second protrusion 430 do not overlap each other in the front and rear directions. is located in Accordingly, the first stick 300 and the second stick 400 may be separated from each other in the front and rear directions. In this case, the first slope part 340 and the second slope part 440 may contact each other.

42 is a state in which the angle between the first stick 300 and the second stick 400 is wider than the separation angle, and the second rotation connection part ( 400R) is shown. As described above, when the first stick 300 and the second stick 400 have a separation angle, the first slope portion 340 and the second slope portion 440 contact each other. In this state, when the angle between the first stick 300 and the second stick 400 is further widened, the first stick 300 is It slides backward as shown by arrow S2, and the second stick 400 slides forward as shown by arrow S1. Then, if the angle between the first stick 300 and the second stick 400 is further increased, the first stick 300 and the second stick 400 may be completely separated as shown in FIG. 43 .

In this way, in the process in which the first stick 300 and the second stick 400 are separated by the slope part, the first protrusion 330 and the second protrusion 430 do not collide with each other or get caught. The reason is that, as described above, rounding is formed on the first protrusion 330 and the second protrusion 430, respectively, and the first protrusion 330 and the second protrusion 430 have a predetermined length (circle) in the circumferential direction. It has a whistle range).

As described above, when the angle between the first stick 300 and the second stick 400 is greater than the separation angle, the first slope 340 and the second slope 440 The first stick 300 and the second stick 400 move apart in the front-rear direction, respectively, and are guided in a direction to be separated from each other. Accordingly, when the angle between the first stick 300 and the second stick 400 increases, the first stick 300 and the second stick 400 may be naturally separated. Accordingly, the user's convenience can be improved. If the slope portion is not provided, when the angle between the first stick 300 and the second stick 400 increases, the upper end of the first stick 300 and the upper end of the second stick 400 collide with each other can do. In this case, accidents such as a broken stick or damage to a rotating connection part may occur. However, according to the embodiment, since the first slope portion 340 and the second slope portion 440 are provided as described above, such an accident can be prevented. That is, when the angle between the first stick 300 and the second stick 400 increases, a collision does not occur and the separation between the first stick 300 and the second stick 400 is naturally performed.

44 is an embodiment provided with a slope part. A slope part is provided at an upper end of any one of the first stick 300 and the second stick 400, and the upper end of the other stick has a guide surface in contact with the slope part. An embodiment provided with this is shown. In FIG. 44 , the first slope portion 340 is provided on the first stick 300 , and the guide surface 440-1 is provided on the second stick 400 .

As shown in FIG. 44 , both the first stick 300 and the second stick 400 do not necessarily have a slope portion, and one stick is provided with a slope portion, and the other stick has a straight guide. An embodiment in which the surface 440-1 is provided is also possible. Preferably, a predetermined rounding may be formed at the end of the guide surface 440-1.

According to the present embodiment, when the angle between the first stick 300 and the second stick 400 is greater than the separation angle, the first slope portion 340 and the guide surface 440-1 are When abutting, the first stick 300 and the second stick 400 may be guided in a direction to be separated from each other while moving away from each other in the front-rear direction. The effect of this embodiment is substantially the same as the embodiment in which the first slope part 340 and the second slope part 440 are provided.

45 is a view showing an embodiment of the tongs-type tool according to the present invention.

According to an embodiment, the first stick 300 is provided at a position between the lower end and the upper end and includes a first support protrusion 35 protruding backward, and the second stick 400 has a lower end and an upper end. It is provided at a position therebetween and includes a second support protrusion 45 protruding rearward. At this time, the weight between the first and second support protrusions 35 and 45 and the upper ends of the first and second sticks 300 and 400 (Pb) is the weight of the first and second support protrusions 35 and 45 and the first and second support protrusions 35 and 45 The weight between the lower ends of the sticks 300 and 400 (Pa) may be greater than the weight. Therefore, when the tongs-type tool according to the present invention is put down on the floor, the first grip portion 32 and the second grip portion 42 do not touch the floor, so that the user's hygiene can be improved.
