[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 charcoal and foodstuffs 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 an object to be gripped 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] Further, the pair of gripping arm portions 12 are formed by vertically bending both ends in the short side direction of an elongated plate-like member. And the pair of gripping portions 18 located at the tips of the pair of gripping arm portions 12 have a plurality of semi-circular notches formed at predetermined intervals in the portions where both ends in the short side direction are vertically bent as shown in FIG. 7.
[0021] As shown in FIG. 7, each of the gripping portions 18a and 18b is formed with six semi-circular notches in pairs. 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 diameters of medium size.
[0022] One end of the pair of gripping operation portions 14 is connected 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 has a substantially V shape. The pair of gripping operation portions 14 is formed by vertically bending both ends in the short side direction of an elongated plate-like member. As shown in FIG. 2, a pair of guide portions 15 are provided on the other end side of the pair of gripping operation portions 14.
[0023] The pair of guide portions 15 are provided on the other end side of the pair of gripping operation portions 14 and have a function of guiding the movement of the pair of gripping arm portions 12 so that the pair of gripping portions 18 approach each other without displacement. The pair of guide portions 15 are formed of rectangular plate-like members as shown in FIG. 2.
[0024] The pair of guide portions 15 includes a first plate portion 16a and a second plate portion 17a on one side, and a first plate portion 16b and a second plate portion 17b on the other side that are paired with them.
[0025] The first plate portion 16a on one side protrudes toward the gripping operation portion 14b on the other side inside the gripping operation portion 14a on one side. The first plate portion 16a on one side is provided on the other end side of the gripping operation portion 14a with respect to the second plate portion 17a on one side. The first plate portion 16a on one side is provided so as to stand up on the plane of the gripping operation portion 14a.
[0026] The second plate portion 17a on one side is provided at a different height position adjacent to the first plate portion 16a on one side inside the gripping operation portion 14a on one side and protrudes toward the gripping operation portion 14b on the other side. The second plate portion 17a on one side is provided on the one end side of the gripping operation portion 14a with respect to the first plate portion 16a on one side. The second plate portion 17a on one side is provided so as to stand up on the plane of the gripping operation portion 14a.
[0027] The other-side first plate portion 16b protrudes toward the one-side gripping operation portion 14a inside the other-side gripping operation portion 14b and is provided at a position at the same height as the one-side second plate portion 17a. The other-side first plate portion 16b is provided on the other end side of the gripping operation portion 14b from the other-side second plate portion 17b. The other-side first plate portion 16b is provided so as to stand up on the plane of the gripping operation portion 14b.
[0028] The other-side second plate portion 17b is provided at a position at the same height as the one-side first plate portion 16a next to the other-side first plate portion 16b inside the other-side gripping operation portion 14b and protrudes toward the one-side gripping operation portion 14a.
[0029] The other-side second plate portion 17b is provided on the one end side of the gripping operation portion 14b from 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 end of the pair of gripping arm portions 12 are connected via the rotation shaft portions 20a, 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, 20b, actually, a connecting pin serving as a rotation fulcrum is installed in these through holes.
[0031] It is possible to shift from the 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 the deployment 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 direction of the pair of gripping operation portions 14a coincides with the longitudinal direction of the pair of gripping arm portions 12.
[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 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 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 stored state, the L-shaped notch portion 26a and the protrusion 24a are not engaged. When the gripping arm portion 12a is rotated in the deployment direction, the protrusion 24 starts to engage with the notch portion 26a. When the gripping arm portion 12a is in the fully deployed state, as shown in FIG. 6, the notch portion 26a and the protrusion 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-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.
[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 so as to release the engagement between the protrusion 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 the diameters of the notch portions have at least two or more types. Here, as described above, in the example shown in FIG. 7, 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] Next, the operation of the tongs 10 with the above configuration will be described. In recent years, with the boom of outdoor activities such as camping, the opportunities for having barbecues outdoors have been increasing. When having a barbecue, tongs are often used to pick up 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 may not be possible to properly grip the charcoal or food. The tongs 10 according to the embodiment of the present invention exhibit remarkable effects against such problems.
[0039] A pair of guide portions 15 are provided on the other end side of the pair of gripping operation portions 14 of the tongs 10. 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 at 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 face each other precisely, achieving a remarkable effect.
[0040] In addition, as shown in FIG. 7, since the pair of gripping portions 18 of the tongs 10 are formed with semi-circular cutout portions 19a having different diameters, there is an advantage that it is possible to firmly grip with any of the cutout portions 19a according to the uneven situation of the gripped object portion of the pair of gripping portions 18.
[0041] Furthermore, as shown in FIG. 8, the tongs 10 can store the pair of gripping arm portions 12 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, it 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 engages with the protrusion portion 24a, the connecting pin moves to the right end portion of the long hole 30a, and the end face 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, during use as the tongs 10, the pair of gripping arm portions 12a will not bend, and the role of the tongs 10 can be fully exerted.
