The connecting portion 5 is composed of an elastic curved portion 6 that is curved in the left-right direction (the direction of the imaginary straight line W) upward (to the right in FIG. 2) and has elasticity. The virtual straight line X is a virtual straight line connecting one grip part 2, the operation handle part 3, the operation part 4, and the elastic curved part 6, and the other grip part 2, operation handle part 3, operation part 4, elastic curve. It is an imaginary straight line located in the middle of the imaginary straight line connecting the shaped parts 6 and defines the vertical direction of the tongue 1, that is, the length direction. The virtual straight line W is a direction when the grip part 2, the operation handle part 3, and the operation part 4 arranged on both sides are paired on the left and right sides, and defines the left and right direction of the tongue 1.

  In the figure, the left and right gripping portions 2 and 2 have the same shape, but the shape and size of the pair of left and right gripping portions 2 and 2 may be the same symmetrically on the left and right, Also good. As a material of the tongue 1, for example, an iron-based material such as stainless steel or a metal material such as aluminum can be used. Further, the entire tongue 1 or only a part of the grip portion 2 or the like may be made of synthetic resin.

  FIG. 3 is a side view when the tongue 1 according to the present embodiment is placed on a flat placement surface 10 such as a cooking table or a table indicated by reference numeral 11 or on a flat portion of the placement surface 10. That is, the tongue 1 is placed in a laid state. The tongue 1 is configured to prevent the pair of left and right grips 2 and 2 from coming into contact with the placement surface 10 when placed on the placement surface 10 in this manner. In such a configuration, in addition to the above-described configuration, a pair of left and right protrusions 7, 7 formed on the mounting surface 10 side when placed on the mounting surface 10 are provided and placed on the mounting surface 10. Sometimes, at least a first contact surface 12 in which a part of the pair of left and right protrusions 7 contacts the mounting surface 10 and a second contact in which a part of the connecting portion 5 contacts the mounting surface 10. This is realized by having the surface 13. Note that the number of contact surfaces is not limited to two, and the entire bottom surface of the tongue 1 located in the lower part of the figure (the lower side of FIG. 3) may contact the placement surface 10. In the present embodiment, the pair of left and right operation units 4 and 4 are formed to be wide (for example, the width A1 is larger than the width A2) downward in the length direction (the direction of the virtual straight line X). However, the shape of the operation unit 4 can be appropriately changed in consideration of ease of gripping and ease of operation.

  It is formed on the mounting surface 10 side when placed on the mounting surface 10 on the lower end side (left side in FIG. 3) in the length direction (the direction of the imaginary straight line X) of the pair of left and right operation units 4 and 4. A pair of left and right first cutout portions 8 and 8 are provided between the pair of left and right projections 7 and 7 and the pair of left and right operation handle portions 3 and 3.

  A pair of left and right second cutout portions 9 and 9 are provided between the pair of left and right operation portions 4 and 4 and the connecting portion 5. The pair of left and right second notches 9, 9 are preferably provided on the surface opposite to the placement surface 10 side (the upper side in FIG. 3) when placed on the placement surface 10.

  The shape and size of the first and second cutout portions 8 and 9 are not particularly limited. However, it is preferable to optimize the shape according to the expected usage of the tongue 1 and to provide a magnitude relationship between the two sizes. With respect to the magnitude relationship, for example, as shown in FIG. 3, the size of the first side view projection area 15 of the first notch 8 is set to the second side view projection area of the second notch 9. Can be larger than 16 sizes. The side view refers to a case where the tongue 1 is viewed from the left-right direction. For convenience, such a magnitude relationship is expressed as the first notch portion 8 being larger than the second notch portion 9. On the contrary, the size of the first side view projection area 15 of the first notch 8 is smaller than the size of the second side view projection area 16 of the second notch 9. That is, the first notch 8 can be made smaller than the second notch 9.

  FIG. 4 is an enlarged view for explaining the shape of the first notch 8. In the figure, the imaginary straight line B passes through the tip point H on the lower side (left side in FIG. 4) of the protrusion 7 and is perpendicular to the placement surface 10 when the tongue 1 is placed on the flat placement surface 10. It is a straight line. This virtual straight line B is intended to indicate the lower boundary position where the edge 21 of the object 20 is inserted. The first notch 8 has a sufficient width B1 from the tip point H on the virtual straight line B to the operation handle 3 and the first notch 8 of the first notch 8 from the center point M1 of the width B1. The first depth B2 from the first insertion position M1 of the first notch 8 to the first bottom R1 is relatively large with the distance B2 to the bottom R1, that is, M1 as the insertion position. Configure. In the present embodiment, the tip of the protrusion 7 is formed in an arc shape, but the shape is not limited to this.

  FIG. 5 is an enlarged view for explaining the shape of the second notch 9. In the figure, the virtual straight line C is a straight line extending downward from the connecting portion 5 on the surface where the second notch portion 9 is provided, and the boundary of the position where the edge portion 21 of the object 20 is inserted. Intended to show. The second notch 9 has a sufficient width C1 on the virtual straight line C, while the distance C2 from the center point M2 of the width C1 to the second bottom R2 of the second notch 9; That is, the second depth C2 from the second insertion position M2 of the second notch 9 to the second bottom R2 is compared with the distance B2 of the first notch 8 with M2 as the insertion position. To make it smaller. In addition, it is preferable to take bottom part R1 and R2 so that 1st depth B2 and 2nd depth C2 may become the maximum, respectively.

  As described above, even when the distance B2 is larger than the distance C2, the first notch 8 is expressed as being larger than the second notch 9. This is because the edge 21 of the object 20 comes into contact with the first and second cutout portions 8 and 9 from the position where the edge 21 is inserted into the first and second cutout portions 8 and 9. The magnitudes of the first and second cutout portions 8 and 9 are compared based on the depths up to. In this case as well, the first notch 8 can be made smaller than the second notch 9.

  The above first side view projection area 15 is the area of the portion surrounded by the virtual straight line B and the first notch 8, and the second side view projection area 16 is the virtual straight line C and This is the area of the portion surrounded by the second notch 9.

  6-9 is a side view which shows the example which hooks and hold | maintains the 1st notch part 8 or the 2nd notch part 9 to the target object 20 which has the edge part 21 which is an upper edge.

  FIG. 6 shows a state in which the first notch portion 8 is held by being hooked on a storage container 25 that is an object 20 having an edge portion 21 with a relatively deep depth and a relatively gentle rise from the bottom surface 22. Indicates. On the other hand, FIG. 7 shows that the first notch 8 is held at the depth of the first notch 8 as in FIG. 6 but is suddenly rising from the bottom surface 22 and hooked to the pot as the object 20 having the edge 21. Shows how it was done. The tongue 1 has at least a pair of left and right first notches when the pair of left and right first cutouts 8 and 8 are engaged with the edge 21 and hooked on the object 20 having the edge 21. A part of the parts 8, 8 has a third contact surface 30 that contacts the edge 21.

  FIG. 8 shows that the second notch 9 is shallower than the storage container 25 of FIG. 6, has a relatively gentle rise from the bottom surface 22, and is a shallow dish 27 as an object 20 having an edge 21. The state of being hooked and held is shown. On the other hand, FIG. 9 shows the second notch 9, the depth is shallow as in FIG. 8, but the rise from the bottom 22 is steep, and the chafer (buffet container) which is the object 20 having the edge 21 Figure 28 shows how it was hooked and held. The tongue 1 has at least a pair of left and right second notches when the pair of left and right second notches 9, 9 are locked to the edge 21 and hooked on the object 20 having the edge 21. A part of the portions 9, 9 has a fourth contact surface 31 that contacts the edge 21.

  As described above, the first notch portion 8 and the second notch portion 9 can be used properly according to the depth, shape, usage situation, and the like of the object 20 having the edge portion 21. These usage examples are only examples, and other usage examples are also possible as appropriate. For example, when the gripping part 2 is not dirty, the gripping part 2 can be pulled out of the object 20 and hooked so that the tongue 1 does not come into contact with the object in the object 20.

  An outline of the manufacturing method of the tongue 1 will be described. In this embodiment, for example, the entire tongue is integrally formed by pressing from a single metal plate such as stainless steel and processed into a finished product shape. For example, when only the grip part 2 is made of a synthetic resin, the grip part 2 can be integrally formed at the lower end of the operation handle part 3 by insert molding or the like.

  The effect | action is demonstrated about said structure. The tongue 1 has a function of gripping a gripping object (not shown) as an essential function of the tongue 1. In a normal state, the pair of left and right grips 2 and 2 are in an open state by the elastic force of the elastic curved portion 6. When trying to grip the object to be gripped, the pair of left and right operation parts 4, 4 are gripped from the outside so that the pair of left and right grip parts 2, 2 resists the elastic force of the elastic curved part 6 in the W direction. The closed state is established, and the object to be grasped can be grasped.

  The first contact surface of the tongue 1 when it is desired to lay the tongue 1 on the mounting surface 10 such as the table or the table 11 during cooking, preparation for cooking, or after cooking. By placing the surface on the 12th side in contact with the mounting surface 10, the state in which the grip portion 2 is floated can be maintained. Thus, after the tongue 1 is once placed, the grip 2 can be kept hygienic and used cleanly without wiping the grip 2 every time it is used again. Further, the mounting surface 10 such as the cooking table or the dining table 11 is not soiled by the juice or oil adhering to the grip portion 2.

  The storage container 25 and the pot 26 having the edge portion 21 having a relatively deep depth may be hooked with the first notch portion 8 having a large notch portion. It is preferable that the second notch 9 having a small notch is hooked on the shallow dish 27 or chafer 28 having the edge 21 having a relatively shallow depth. In this way, the object 20 having various depths and shapes can be selected and hooked by selecting either the first notch 8 or the second notch 9 of the tongue 1. 1 can be stably held on the object 20

  For example, in a buffet or the like, a large number of general customers use the same tongs 1 to share dishes. At this time, the manner of placing the tongue 1 differs depending on the person, and not all customers place the tongue 1 firmly and stably on the chafer. However, the provision of the first and second cutouts 8 and 9 makes it easy for any customer to temporarily place the tongue 1 on the chafer, and prevents the tongue 1 from sliding down inside the chafer 28. be able to.

  Tongs 1 are often used during preparations for cooking, during cooking, and after cooking, but there may not be enough space for the tongs 1 to lie on the table or table 11 Many. Even in such a case, the tongue 1 can easily be temporarily placed by hooking the first notch 8 or the second notch 9 on the object 20. Even when the object 20 is moved while the tongue 20 is hooked on the object 20, the third contact surface 30 of the first notch 8 or the second notch 9. Since the fourth contact surface 31 is firmly and stably held on the edge 21 of the object 20, the tongue 1 can be prevented from slipping into the object 20.
