[0018] The tongs 10 include a pair of gripping arm portions 12, a pair of gripping operation portions 14, and a pair of guide portions 15. The tongs 10 have a function of sandwiching an object to be gripped. There are various objects to be gripped, and here, although it will be described as including, for example, charcoal and food for barbecue, of course, others are also included.

[0019] The pair of gripping arm portions 12 have a pair of gripping portions 18 for gripping a gripped object portion at one end. The pair of gripping arm portions 12 are rotatably connected to the pair of gripping operation portions 14 via a pair of rotation shaft portions 20a and 20b at the other end. In the examples of FIGS. 5 and 6, although through holes are shown in the portions of the rotation shaft portions 20a and 20b, actually, a connecting pin (not shown) serving as a rotation fulcrum is installed in these through holes.

[0020] Also, the pair of gripping arm portions 12 are formed by vertically bending both end portions in the short side direction of an elongated plate-shaped member. And the pair of gripping portions 18 located at the tips of the pair of gripping arm portions 12 are formed with a plurality of semi-circular notches at predetermined intervals in the portions where both end portions in the short side direction are vertically bent as described above, as shown in FIG. 7.

[0021] As shown in FIG. 7, six semi-circular notches are formed in each of the gripping portions 18a and 18b so as to be paired. In the example shown in FIG. 7, the three notches 19a on the right side have the largest diameter, the one notch 19a on the far left has the smallest diameter, and the remaining two have medium-sized diameters.

[0022] The pair of gripping operation portions 14 are connected at one end to the other end of each gripping arm portion 12, and the other ends are connected to each other. The pair of gripping operation portions 14 have a substantially V shape. The pair of gripping operation portions 14 are formed by vertically bending both end portions in the short side direction of an elongated plate-shaped member. A pair of guide portions 15 are provided on the other end side of the pair of gripping operation portions 14, as shown in FIG. 2.

[0023] The pair of guide parts 15 are provided on the other end side of the pair of gripping operation parts 14, and have a function of guiding the movement of the pair of gripping arm parts 12 so that the pair of gripping parts 18 approach without displacement. As shown in FIG. 2, the pair of guide parts 15 are composed of rectangular plate-like members.

[0024] The pair of guide parts 15 include a first plate part 16a and a second plate part 17a on one side, and a first plate part 16b and a second plate part 17b on the other side corresponding thereto.

[0025] The first plate part 16a on one side protrudes toward the gripping operation part 14b on the other side inside the gripping operation part 14a on one side. The first plate part 16a on one side is provided on the other end side of the gripping operation part 14a with respect to the second plate part 17a on one side. The first plate part 16a on one side is provided so as to stand up on the plane of the gripping operation part 14a.

[0026] The second plate part 17a on one side is provided at a position of a different height adjacent to the first plate part 16a on one side inside the gripping operation part 14a on one side, and protrudes toward the gripping operation part 14b on the other side. The second plate part 17a on one side is provided on the one end side of the gripping operation part 14a with respect to the first plate part 16a on one side. The second plate part 17a on one side is provided so as to stand up on the plane of the gripping operation part 14a.

[0027] The first plate part 16b on the other side protrudes toward the gripping operation part 14a on one side inside the gripping operation part 14b on the other side, and is provided at a position having the same height as the second plate part 17a on one side. The first plate part 16b on the other side is provided on the other end side of the gripping operation part 14b with respect to the second plate part 17b on the other side. The first plate part 16b on the other side is provided so as to stand up on the plane of the gripping operation part 14b.

[0028] The second plate part 17b on the other side is provided at a position having the same height as the first plate part 16a on one side adjacent to the first plate part 16b on the other side inside the gripping operation part 14b on the other side, and protrudes toward the gripping operation part 14a on one side.

[0029] The other-side second plate portion 17b is provided on one end side of the gripping operation portion 14b with respect to the other-side first plate portion 16b. The other-side second plate portion 17b is provided so as to stand up on the plane of the gripping operation portion 14b.

[0030] The other ends of the pair of gripping operation portions 14a and one ends of the pair of gripping arm portions 12 are connected via rotation shaft portions 20a and 20b. As described above, in the examples of FIGS. 5 and 6, although through holes are shown in the portions of the rotation shaft portions 20a and 20b, actually, a connecting pin serving as a rotation fulcrum is installed in these through holes.

[0031] It is possible to shift from a storage state (see FIG. 8) in which the pair of gripping arm portions 12 are rotated in the storage direction and the pair of gripping arm portions 12 are stored in the pair of gripping operation portions 14 to a deployed state (see FIGS. 1 and 2) in which the pair of gripping arm portions 12 are rotated in the deployment direction, which is the direction opposite to the storage direction, so that the longitudinal directions of the pair of gripping operation portions 14a and the pair of gripping arm portions 12 coincide.

[0032] The restricting portion 25 restricts the rotation of the pair of gripping arm portions 12 when shifting to the deployed state. As shown in FIG. 6, the restricting portion 25 includes a long hole 30a formed in the gripping arm portion 12a, a protrusion portion 24a formed in the gripping operation portion 14a, an L-shaped notch portion 26a formed in the gripping arm portion 12a and capable of guiding the protrusion portion 24a, a contact portion 32a formed in the gripping arm portion 12a, and a leaf spring-like stopper portion 28a formed in the gripping operation portion 14a.

[0033] When the pair of gripping arm portions 12 are in the storage state, the L-shaped notch portion 26a and the protrusion portion 24a are not engaged. When the gripping arm portion 12a is rotated in the deployment direction, the protrusion portion 24 starts to engage with the notch portion 26a. When the gripping arm portion 12a is in the complete deployed state, as shown in FIG. 6, the notch portion 26a and the protrusion portion 24a are engaged.

[0034] At this time, the connecting pin moves to the right end of the long hole 30a, and the end face of the contact portion 32a contacts the leaf spring-shaped stopper portion 28a that has moved inside the gripping operation portion 14a, restricting the movement of the contact portion 32a of the gripping arm portion 12a so that it does not move to the other end side of the gripping operation portion 14a, and maintaining the deployed state of the gripping arm portion 12a.

[0035] After that, when shifting the gripping arm portion 12a to the stored state, the stopper portion 28a is pressed to release the contact between the contact portion 32a and the stopper portion 28a, and the gripping arm portion 12a is moved to cancel the engagement between the protrusion portion 24a and the notch portion 26a, and then the gripping arm portion 12a is rotated.

[0036] A plurality of semi-circular notch portions 19a are formed in each gripping portion 18, and there are at least two or more types of diameters of the notch portions. Here, as described above, in the example shown in FIG. 7, it will be described that the three notches on the right side have the largest diameter, the one notch on the far left has the smallest diameter, and the remaining two have the middle diameter. Of course, the number and size of the holes are not limited to these.

[0037] Subsequently, the operation of the tongs 10 having the above configuration will be described. In recent years, with the boom of outdoor activities such as camping, the opportunities for outdoor barbecues have been increasing. In barbecues, tongs are often used to grasp charcoal, food, etc.

[0038] In general tongs, the longer the length, the more likely it is that when closing a pair of gripping portions located at the tip of the tongs, there will be a displacement and it will be difficult to properly grip charcoal or food. The tongs 10 according to the embodiment of the present invention exhibit remarkable effects against such problems.

[0039] The tongs 10 are provided with a pair of guide portions 15 on the other end side of the pair of gripping operation portions 14. When the tongs 10 are open, as shown in FIG. 3, the pair of guide portions 15 are in a separated state. However, when the user holds the other ends of the pair of gripping operation portions 14 of the tongs 10 and tries to close the pair of gripping operation portions 14, as shown in FIG. 4, the first plate portion 16a on one side and the first plate portion 16b on the other side approach each other while remaining in a substantially contacting state at different heights, and the second plate portion 17a on one side and the second plate portion 17b on the other side approach each other while remaining in a substantially contacting state with a height relationship opposite to that of the first plate portion 16a on one side and the first plate portion 16b on the other side. As a result, the pair of gripping arm portions 12a located at the tip side are guided to close without displacement, and the pair of gripping portions 18 can be closed in a state where they exactly face each other, achieving a remarkable effect.

[0040] Also, as shown in FIG. 7, the pair of gripping portions 18 of the tongs 10 are formed with semi-circular cutout portions 19a having different diameters. Therefore, there is an advantage that the pair of gripping portions 18 can firmly grip with any of the cutout portions 19a according to the uneven situation of the gripped object portion.

[0041] Furthermore, as shown in FIG. 8, the pair of gripping arm portions 12 of the tongs 10 can be housed in the pair of gripping operation portions 14. However, by rotating the pair of gripping arm portions 12 about the rotation shaft portions 20a and 20b as rotation axes, they can be shifted to the deployed state as shown in FIG. 5. By further rotating, the longitudinal directions of the pair of gripping arm portions 12 and the pair of gripping operation portions 14 can be made to coincide to achieve a complete deployed state.

[0042] At this time, the notch portion 26a and the protrusion portion 24a are engaged, and the connecting pin moves to the right end portion of the long hole 30a, and the end surface of the contact portion 32a contacts the leaf spring-like stopper portion 28a that has moved inside the gripping operation portion 14a, restricting the movement of the contact portion 32a of the gripping arm portion 12a so that it does not move to the other end side of the gripping operation portion 14a, and maintaining the deployed state of the gripping arm portion 12a. As a result, the pair of gripping arm portions 12a will not bend while the tongs 10 are in use, and the role of the tongs 10 can be fully exerted.
