However, in the above-mentioned tongs, when the gripping / releasing operation is performed by the operating portion, the elastic curved portion tends to be twisted, so that the pair of left and right gripped portions are displaced from each other, and the gripping object can be gripped well. Sometimes I couldn't grasp it. In addition, since the above-mentioned tongs have a large amount of elastic deformation in the elastically curved portion during the gripping / releasing operation, the elastically curved portion may be plastically deformed and the gripped portion may be difficult to open.

Therefore, it is an object of the present invention to provide an easy-to-use tong in which a pair of left and right grip portions are not displaced from each other and the curved portion connecting the operation portions is not plastically deformed.

The tongs of the present invention are provided on one end side of a pair of gripping portions facing each other to grip an object to be gripped, and are provided on the other end side of the pair of gripping portions to perform gripping / releasing operations by the gripping portions. A pair of operating portions and a curved portion that integrally connects the other end sides of the pair of the operating portions are provided, the operating portion and the curved portion are integrally formed from a metal plate, and the operating portion is the curved portion. It is characterized in that an elastic portion is partially provided on the other end side extending toward, and the portion of the operation portion and the curved portion excluding the portion where the elastic portion is formed are configured so as not to be elastically deformed. do.

Further, the length of the elastic portion is formed to be larger than the width of the elastic portion.

Further, the operation portion is formed in a substantially flat plate shape, and the thickness of the elastic portion is formed to be thinner than the thickness of the operation portion.

According to the tongs of the present invention, the operating portion and the curved portion are integrally formed from a metal plate, and the operating portion is partially provided with an elastic portion on the other end side extending toward the curved portion and is elastic. The portion of the operation portion and the curved portion other than the portion where the portion is formed are configured so as not to be elastically deformed. Since the elastic portion is formed of a metal plate and acts so as to elastically deform only in one direction that minimizes the elastic force, the pair of left and right grip portions do not shift from each other. Further, since the elastic portion is elastically deformed at two places, the amount of elastic deformation in each elastic portion is reduced, and the elastic portion is not plastically deformed.

Further, since the length of the elastic portion is formed to be larger than the width of the elastic portion, the amount of elastic deformation per unit area is small, and the elastic portion is not plastically deformed.

Further, since the operation portion is formed in a substantially flat plate shape and the thickness of the elastic portion is thinner than the thickness of the operation portion, the elastic portion can be easily formed by rolling and annealing.

It is a perspective view which shows one Example of the tongs of this invention. It is an enlarged cross-sectional view of the operation part near the elastic part which shows one Example of the tongs of this invention.

The tongs of the present invention will be described in more detail based on the following examples. The present invention is not limited to the following examples, and various modifications can be made without departing from the idea of the present invention.

In FIG. 1 showing the tongs of this embodiment, reference numeral 1 denotes a tong, which is manufactured by machining an elongated metal plate such as stainless steel. A pair of left and right gripping portions 3A and 3B for gripping a gripping object 2 such as food are provided on one end side of the tongs 1 so as to face each other. A pair of left and right operating portions 4A, 4B for performing gripping / releasing operations by the gripping portions 3A, 3B extend from the gripping portions 3A, 3B toward the other end side so as to face each other. Further, on the other end side of the operation portions 4A and 4B, a curved portion 5 that is smoothly curved in the left-right direction and integrally connects the operation portions 4A and 4B is provided. Further, the grip portions 3A and 3B are formed in a shape like a scooping portion of a spoon having an uneven portion 6 formed on the edge. In this embodiment, the grip portions 3A and 3B are integrally formed with the operation portions 4A and 4B, but they may be formed of synthetic resin.

The operation portions 4A and 4B are each formed in an elongated and substantially flat plate shape, and are partially provided with elastic portions 7A and 7B on the other end side extending toward the curved portion 5, respectively. The length L of the elastic portions 7A and 7B in the direction from one end side to the other end side is formed to be larger than the width W in the direction orthogonal to the length L. Further, as shown in the cross-sectional view of FIG. 2, the elastic portions 7A and 7B are also formed in a substantially flat plate shape, and the thickness A of the elastic portions 7A and 7B is thinner than the thickness B of the operation portions 4A and 4B. It is formed. Then, only the elastic portions 7A and 7B which are partially formed thin on the other end side of the operating portions 4A and 4B are elastically deformed, and the operating portions 4A and 4B excluding the portions where the elastic portions 7A and 7B are formed. The portion and the curved portion 5 are configured so as not to be elastically deformed.

The method of manufacturing the tongs 1 of this embodiment will be described. First, an elongated metal plate material of an appropriate size is prepared, and the portions corresponding to the elastic portions 7A and 7B are rolled thinly by rolling. Next, if necessary, the rolled portion is annealed. By these processes, a metal plate material in which only the portions corresponding to the elastic portions 7A and 7B are thin and elastically deformed can be obtained. Then, the tongs 1 are obtained by processing the portions corresponding to the grip portions 3A and 3B of the metal plate material into a predetermined shape, bending the portions corresponding to the curved portions 5, and finally performing finishing processing such as polishing. Be done.

The operation of the tongs 1 of this embodiment will be described. In the tongs 1 when not in use, as shown in FIG. 1, the pair of left and right grip portions 3A and 3B are in an open state. Then, by gripping the pair of left and right operating portions 4A and 4B from the outside, the pair of left and right grip portions 3A and 3B are closed against the elastic force of the elastic portions 7A and 7B, and the gripping object 2 is held. Can be grasped. At this time, only the elastic portions 7A and 7B are elastically deformed, and the curved portion 5 is not elastically deformed. Further, the elastic portions 7A and 7B are formed of a substantially flat metal plate, and act so as to elastically deform only in one direction so as to minimize the elastic force. Therefore, unlike the conventional tongs, the curved portion 5 does not twist and the pair of left and right grip portions 3A and 3B do not shift from each other.

Further, as compared with the conventional tongs in which the curved portion 5 is elastically deformed at one place, in the tongs 1 of the present embodiment, the elastic parts 7A and 7B are elastically deformed at two places, so that the elastic parts 7A, respectively. The amount of elastic deformation in 7B is reduced. Further, since the length L of the elastic portions 7A and 7B is formed larger than the width W, the amount of elastic deformation per unit area is small. As a result, the elastic portions 7A and 7B are not plastically deformed even after repeated use.

As described above, the tongs 1 of the present embodiment are provided so as to face each other on one end side and grip the gripping object 2, the pair of grip portions 3A and 3B, and the other end side of the pair of grip portions 3A and 3B. A pair of operating portions 4A and 4B for performing gripping / releasing operations by the gripping portions 3A and 3B, and a curved portion 5 for integrally connecting the other end sides of the pair of operating portions 4A and 4B are provided. The operating portions 4A and 4B and the curved portion 5 are integrally formed from a metal plate, and the operating portions 4A and 4B are partially provided with elastic portions 7A and 7B on the other end side extending toward the curved portion 5. At the same time, the portions of the operating portions 4A and 4B and the curved portion 5 except for the portions where the elastic portions 7A and 7B are formed are configured not to be elastically deformed. Therefore, the elastic portions 7A and 7B are formed of a metal plate and act so as to elastically deform only in one direction so as to minimize the elastic force, so that the pair of left and right grip portions 3A and 3B are displaced from each other. There is no. Further, since the elastic portions 7A and 7B are elastically deformed at two places, the amount of elastic deformation in each of the elastic portions 7A and 7B is reduced, and the elastic portions 7A and 7B are not plastically deformed.

Further, since the length L of the elastic portions 7A and 7B is formed to be larger than the width W of the elastic portions 7A and 7B, the amount of elastic deformation per unit area becomes small, and the elastic portions 7A and 7B are plastically deformed. There is nothing to do.

Further, since the operation portions 4A and 4B are formed in a substantially flat plate shape and the thickness A of the elastic portions 7A and 7B is formed thinner than the thickness B of the operation portions 4A and 4B, rolling and annealing are performed. The elastic portions 7A and 7B can be easily formed.
