Description

[Technical Field]

[0001] This invention relates to a trivet that is installed on a heat source such as an oil stove. [Background technology]

[0002] A stove equipped with a heat generating means such as a burner within the frame has an opening in the center of the top plate at the top of the frame for discharging high-temperature combustion gases generated by the burner, and a trivet on the top plate around the opening, and is used for cooking by placing cooking utensils on the trivet.

[0003] Furthermore, oil heaters are provided with a heat generating means such as a burner within the frame and a top plate on top of the frame, on which a kettle, pot, etc. can be placed (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-37481 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, oil stoves have come to be used for heating purposes as outdoor equipment for camping, etc. As a result, they are increasingly being used for simple cooking by placing cooking utensils on the stove top.

[0006] However, kerosene stoves, which are primarily used for heating, do not have a trivet and cooking utensils are placed directly on the top, which makes the utensils unstable and raises safety concerns.In addition, when cooking utensils are placed on the top, the temperature of the top rises, causing deterioration such as discoloration and peeling of the paint, and resulting in a poor appearance.

[0007] An object of the present invention is to provide a trivet that can be installed on the top plate of a kerosene stove, allowing cooking utensils to be used safely. [Means for solving the problem]

[0008] The present invention solves the above-mentioned problems and provides a trivet (1) that is placed on a heat source and on which an object to be heated is placed, the trivet (1) being composed of first and second leg plates (2, 3) that intersect in a crisscross pattern and a top plate (4) that is placed on the first and second leg plates (2, 3), and having a pair of locking projections (23, 33) formed on the upper ends of the first and second leg plates (2, 3), a fitting groove (22) formed in the central upper end of the first leg plate (2), and a fitting groove (32) formed in the central lower end of the second leg plate (3); The top plate 4 is provided with a locking portion 42 that locks with the locking piece protrusions 23, 33 of the first and second leg plates 2, 3, and the first and second leg plates 2, 3 are arranged in a cross shape so that the mating grooves 22, 32 fit together.When the top plate 4 is placed on the first and second leg plates 2, 3, the locking portion 42 engages with the locking protrusions 23, 33, thereby locking the first and second leg plates 2, 3 and the top plate 4 to each other.

[0009] In addition, the fitting groove 22 of the first leg plate 2 may be formed in a substantially L-shape and include a horizontal groove portion 22A and a locking piece 22B, and the second leg plate 3 may be provided with a recess 32A at the central upper end opposite to the fitting groove 32, so that the first and second leg plates 2 and 3 intersect in a cross shape, with the horizontal groove portion 22A of the fitting groove 22 of the first leg plate 2 fitting into the fitting groove 32 of the second leg plate 3, and the locking piece 22B of the first leg plate 2 fitting into the recess 32A of the second leg plate 3, and by positioning the second leg plate 3 below the locking piece 22B, the fitting of the first and second leg plates 2 and 3 cannot be easily disengaged.

[0010] In addition, the side wall portion of the mating groove 22 of the first leg plate 2 opposite the horizontal groove portion 22A may be provided with an inclined guide portion 22C that guides the second leg plate 3 into the horizontal groove portion 22A of the mating groove 22 while sliding it, and by simply inserting the second leg plate 3 into the mating groove 22 of the first leg plate 2, the second leg plate 3 will fit into the horizontal groove portion 22A of the mating groove 22 of the first leg plate 2.

[0011] In addition, a vertical rising portion 22D may be provided between the bottom wall portion of the fitting groove 22 of the first leg plate 2 and the inclined guide portion 22C, so that when the second leg plate 3 is guided into the horizontal groove portion 22A of the fitting groove 22 of the first leg plate 2, the inclination of the second leg plate 3 is corrected and the second leg plate 3 becomes upright.

[0012] In addition, the locking protrusions 23, 33 may be arranged at both ends of the first and second leg plates 2, 3, and the locking protrusions 23, 33 may be positioned outside the outer peripheral end of the top plate 4, and the locking protrusions 23, 33 will stop the movement of the object to be heated placed on the top plate 4 and prevent it from falling. [Effects of the Invention]

[0013] As in the present invention, by placing trivet 1 on top plate 6 of oil stove 5 and placing cooking utensils or other objects to be heated on trivet 1, the objects to be heated are stabilized and can be used safely. In addition, since the objects to be heated are no longer placed directly on top plate 6 of oil stove 5, deterioration such as discoloration and peeling of the paint on top plate 6 of oil stove 5 can be prevented.

[0014] Furthermore, the simple structure allows for easy disassembly and assembly, and when not in use or when transporting, it can be disassembled and stored compactly, providing a trivet that is easy to handle. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of an oil burner of the present invention will be described with reference to the drawings.

[0017] Fig. 1 is a perspective view of a trivet according to an embodiment of the present invention, and Fig. 2 is a perspective view of the trivet disassembled. Trivet 1 of this embodiment is composed of a first leg plate 2, a second leg plate 3, and a top plate 4. Trivet 1 can be disassembled and reassembled, with first leg plate 2 and second leg plate 3 crossing each other in a crisscross pattern, and top plate 4 resting on top of the crossed first and second leg plates 2 and 3.

[0018] The first leg plate 2 and the second leg plate 3 each have legs 21 and 31 extending downward from both ends. Figure 3 is a perspective view showing the trivet 1 attached to an oil burner in use. When the trivet 1 is attached to the top plate 6 of the oil burner 5, the legs 21 and 31 rest on the guard 7 of the oil burner 5, and the top plate 4 is positioned on top of the top plate 6. At this time, the top plate 4 of the trivet 1 is installed with a specified distance between it and the top plate 6 of the oil stove 5.

[0019] 2, the first leg plate 2 has a fitting groove 22 at its central upper end, and locking protrusions 23 protruding upward from the upper end at both ends. The depth dimension of the fitting groove 22 is half the vertical width of the central part of the first leg plate 2, and the horizontal dimension of the fitting groove 22 is larger than the plate thickness of the second leg plate 3 so that the second leg plate 3 can be fitted therein. In addition, the leg portions 21 are positioned outward of the locking protrusions 23.

[0020] The second leg plate 3 has a fitting groove 32 at its lower central end, and locking protrusions 33 at both ends that protrude upward from the upper ends. The depth dimension of the fitting groove 32 is half the vertical width of the central part of the second leg plate 3, and the horizontal dimension of the fitting groove 32 is larger than the plate thickness of the first leg plate 2 so that the first leg plate 2 can be fitted into it. In addition, the leg parts 31 are positioned outward of the locking protrusions 33.

[0021] The first leg plate 2 and the second leg plate 3 differ only in the fitting grooves 22 and 32, and other parts have the same shape and dimensions.

[0022] The top plate 4 is circular or polygonal. In this embodiment, it is a regular dodecagon as shown in Fig. 2. The top plate 4 has a plurality of through holes 41 on the surface on which the object to be heated is placed, and is provided with a locking portion 42 formed of a concave groove at the outer edge.

[0023] The outer peripheral edge of the top plate 4, which has the locking portions 42, is located outward from the ends of the locking protrusions 23, 33 of the first and second leg plates 2, 3, and the inner edge of the groove of the locking portion 42 is located inward from the ends of the locking protrusions 23, 33. In addition, the width dimension of the locking portions 42 is greater than the plate thickness of the first and second leg plates 2, 3, so that when the first and second leg plates 2, 3 and the top plate 4 are assembled, the locking portions 42 of the top plate 4 can fit into the locking protrusions 23, 33 of the first and second leg plates 2, 3.

[0024] Next, we will explain the procedure for assembling the trivet 1. First, the first and second leg plates 2 and 3 are placed one on top of the other, with the first leg plate 2 on the bottom and the second leg plate 3 on top, and the fitting groove 22 of the first leg plate 2 is fitted into the fitting groove 32 of the second leg plate 3, so that the first and second leg plates 2 and 3 intersect in a crisscross pattern. In this state, the positions of the upper and lower ends of the first and second leg plates 2 and 3 are aligned.

[0025] Next, align the locking portion 42 of the top plate 4 with the locking protrusions 23 and 33 of the first and second leg plates 2 and 3, and place the top plate 4 on the first and second leg plates 2 and 3, and the locking portion 42 of the top plate 4 will fit into the locking protrusions 23 and 33.

[0026] The engagement of the locking projections 23, 33 of the first and second leg plates 2, 3 with the locking portions 42 of the top plate 4 regulates the positions of the first and second leg plates 2, 3 and the top plate 4 relative to each other, preventing the first and second leg plates 2, 3 from tilting and falling over, and preventing the angle of intersection from changing.

[0027] Furthermore, when the trivet 1 is lifted up to be attached to the top plate 6 of the oil burner 5, the angle between the intersecting first and second leg plates 2 and 3 is maintained, so the legs 21 and 31 can be easily placed on the guard 7 of the oil burner 5. Furthermore, the top plate 4 will not come off the first and second leg plates 2 and 3, and the shape of the trivet 1 is stable without the need for fixing screws or the like.

[0028] By placing cooking utensils, such as pots, on the top plate 4 of the trivet 1, the cooking utensils are stabilized. In this embodiment, the locking projections 23 and 33 of the first and second leg plates 2 and 3 protrude above the top plate 4 from the locking portions 42, and the ends of the locking projections 23 and 33 are located inside the outer periphery of the top plate 4. Therefore, cooking utensils that can be placed on the top plate 4 are limited to those that fit inside the ends of the locking projections 23 and 33, and cooking utensils will not be placed beyond the top plate 4. In addition, the locking projections 23 and 33 that protrude above the top plate 4 stop the cooking utensils from moving, preventing them from falling off the top plate 4.

[0029] When putting away the trivet 1 after use, the trivet 1 is removed from the oil burner 5, the top plate 4 is removed, and then the second leg plate 3 is lifted up, allowing the second leg plate 3 to be removed from the first leg plate 2. As no fixing screws or the like are required when assembling the trivet 1, assembly and disassembly are simple, providing a trivet 1 that is easy to handle.

[0030] In this embodiment, the locking protrusions 23 and 33 are provided at both ends of the first and second leg plates 2 and 3, and the locking portion 42 is configured as a concave groove provided on the outer peripheral edge of the top plate 4, but this configuration is not limited to this.The locking protrusions 23 and 33 may be provided inward from both ends of the first and second leg plates, and the locking portion 42 may be configured as a hole provided inward from the outer peripheral edge of the top plate 4, so that the locking protrusions 23 and 33 fit into the hole that constitutes the locking portion 42.

[0031] Fig. 4 is a perspective view of first and second leg plates 2 and 3 according to another embodiment of the present invention, and Fig. 5 is an explanatory diagram showing the assembly procedure for the first and second leg plates 2 and 3. As shown in Fig. 4, the first leg plate 2 has an L-shaped fitting groove 22 and is provided with a horizontal groove portion 22A and a locking piece 22B continuing from the upper end. On the other hand, the second leg plate 3 has a fitting groove 32 provided at the lower central end and a recess 32A at the upper end opposite the fitting groove 32.

[0032] The height dimension from the central lower end of the first leg plate 2 to the bottom wall of the fitting groove 22 is approximately the same as the depth dimension of the fitting groove 32 of the second leg plate 3, and the depth dimension of the recess 32A of the second leg plate 3 is greater than the height dimension of the locking piece 22B of the first leg plate 2. In addition, the distance between the side wall portion of the fitting groove 22 of the first leg plate 2 and the end of the locking piece 22B is set greater than the plate thickness of the second leg plate 3.

[0033] When assembling the first leg plate 2 and the second leg plate 3, the first and second leg plates 2 and 3 are overlapped with each other so that the first leg plate 2 is on the bottom and the second leg plate 3 is on the top, as shown in Figure 5(a), and the fitting groove 22 of the first leg plate 2 is fitted into the fitting groove 32 of the second leg plate 3, resulting in the state shown in Figure 5(b). From this state, the second leg plate 3 is slid laterally into the horizontal groove portion 22A of the fitting groove 22, resulting in the state shown in Figure 5(C), in which the first and second leg plates 2 and 3 cross in a crisscross pattern at their centers and the heights of the central upper ends of the first and second leg plates 2 and 3 are aligned.

[0034] When the locking portion 42 of the top plate 4 is aligned with the locking projections 23, 33 of the first and second leg plates 2, 3 and the top plate 4 is placed on the first and second leg plates 2, 3, the locking portion 42 of the top plate 4 engages with the locking projections 23, 33, and the trivet 1 is assembled.

[0035] With this configuration, if one tries to lift up only one of the first and second leg plates 2 and 3, the recess 32A of the second leg plate 3 will catch on the locking piece 22B of the first leg plate 2 and lift up together, preventing the first and second leg plates 2 and 3 from coming off and falling apart. Therefore, the trivet 1 can be easily placed on the guard 7 of the oil burner 5.

[0036] Furthermore, when putting away the trivet 1 after use, the trivet 1 is removed from the oil burner 5, the top plate 4 is removed, and then the second leg plate 3 is slid horizontally to move out of the horizontal groove portion 22A and then pulled up vertically, thereby removing the second leg plate 3 from the first leg plate 2. As a result, the trivet 1 can be assembled and disassembled very easily, providing a trivet 1 that is easy to handle.

[0037] Fig. 6 is a perspective view of first and second leg plates 2 and 3 according to another embodiment of the present invention, and Fig. 7 is an explanatory diagram showing the assembly procedure for the first and second leg plates 2 and 3. As shown in Fig. 6, the first leg plate 2 has a horizontal groove 22A and a locking piece 22B in the fitting groove 22, and an inclined guide portion 22C on the side wall opposite the horizontal groove 22A. Also, a vertical rising portion 22D is provided between the bottom wall of the fitting groove 22 and the inclined guide portion 22C. Meanwhile, the second leg plate 3 has a fitting groove 32 provided at the lower central end and a recess 32A at the upper end opposite the fitting groove 32.

[0038] The height dimension from the central lower end of the first leg plate 2 to the bottom wall of the fitting groove 22 is approximately the same as the depth dimension of the fitting groove 32 of the second leg plate 3, and the depth dimension of the recess 32A of the second leg plate 3 is set to be larger than the height dimension of the engagement portion 22B of the first leg plate 2.

[0039] The width between the side wall of the horizontal groove portion 22A and the rising portion 22D is larger than the thickness of the second leg plate 3 so that the second leg plate 3 can be fitted in. The inclined guide portion 22C is configured so that the opening width of the fitting groove 22 increases upward from the rising portion 22D.

[0040] When assembling the first leg plate 2 and the second leg plate 3, the first and second leg plates 2 and 3 are overlapped with each other so that the first leg plate 2 is on the bottom and the second leg plate 3 is on the top, as shown in Figure 7(a), and the fitting groove 32 of the second leg plate 3 is inserted into the fitting groove 22 of the first leg plate 2, so that the bottom wall of the fitting groove 32 of the second leg plate 3 comes into contact with the inclined guide portion 22C. The second leg plate 2 slides along the inclined guide portion 22C in an inclined state, and the fitting groove 32 of the second leg plate 3 is guided into the horizontal groove portion 22A of the first leg plate 2, resulting in the state shown in Figure 7(b).

[0041] In this state, the second leg plate 3 changes direction at the rising portion 22D and stands upright, and is sandwiched between the side wall portion of the horizontal groove portion 22A of the first leg plate 2 and the rising portion 22D, with the mating groove 32 resting on the bottom wall surface of the horizontal groove portion 22D, resulting in the state shown in Figure 7(c), where the first and second leg plates 2 and 3 intersect in a cross shape at their central positions and the heights of the central upper ends of the first and second leg plates 2 and 3 are aligned.

[0042] With this configuration, when engaging the engaging groove 22 of the first leg plate 2 with the engaging groove 32 of the second leg plate 3, there is no need to move the second leg plate 3 into the horizontal groove portion 22A of the engaging groove 22, and the first and second leg plates 2 and 3 can be engaged and assembled in the correct position without the worker having to pay special attention to it.

[0043] When the locking portion 42 of the top plate 4 is aligned with the locking projections 23, 33 of the first and second leg plates 2, 3 and the top plate 4 is placed on the first and second leg plates 2, 3, the locking portion 42 of the top plate 4 engages with the locking projections 23, 33, and the trivet 1 is assembled.

[0044] When the trivet 1 is assembled and an attempt is made to lift one of the first and second leg plates 2 and 3, the recess 32A of the second leg plate 3 catches on the locking piece 22B of the first leg plate 2, causing the first and second leg plates 2 and 3 to be lifted together, preventing them from coming off and falling apart. This allows the trivet 1 to be easily placed on the guard 7 of the oil burner 5.

[0045] Furthermore, when putting away the trivet 1 after use, the trivet 1 is removed from the oil burner 5, the top plate 4 is removed, and then the second leg plate 3 is tilted and pulled up along the inclined guide portion 22C, thereby removing the second leg plate 3 from the first leg plate 2. Therefore, the trivet 1 can be assembled and disassembled very easily, providing a trivet 1 that is easy to handle. [Explanation of symbols]
