[0023] With this, when the fire pit is not in use, it can be disassembled into three receiving members, the three support legs, and the connecting member, allowing it to be stored compactly.

[0024] The invention described in claim 8 is the invention described in claim 7, An engagement hole (20b) is formed in the middle of each of the three support legs, A second engaging projection (30b) protruding inward is formed in the portion of the connecting member where the insertion hole is formed, The second engagement protrusion is inserted into and engaged with the engagement hole.

[0025] According to this, the second engaging protrusion is inserted into the engaging hole and engaged, thereby connecting the support leg to the connecting member. Therefore, the support leg and the connecting member are prevented from moving relative to each other, the support leg is firmly connected by the connecting member, and the fire pit is stabilized.

[0026] The invention described in claim 9 is the invention described in claim 7, The connecting member has one support hole (30c) formed therein, A third engagement projection (9b) projecting downward is formed at the apex of the receiving member, The three third engagement protrusions are inserted into and engaged with the support holes.

[0036] (Structure of a fire pit) Below, a fire pit 100 according to one embodiment of the present invention will be described with reference to Figures 1 to 5. As shown in Figures 1 and 2, the fire pit 100 is made up of a receiving part 10, three support legs 20, an ash pan 30 (connecting member), and three locking members 40. The receiving part 10, the three support legs 20, and the ash pan 30 are made of stainless steel such as SUS304, which has excellent corrosion resistance.

[0037] 1, the receiving part 10 has a triangular pyramid shape with an opening at the top, and is used to receive combustible materials such as firewood. In this embodiment, the receiving part 10 is made up of three receiving members 9, and can be disassembled into the three receiving members 9.

[0038] As shown in FIG. 3, the receiving member 9 is composed of a frame portion 4, a see-through portion 5, and a fall suppression plate 6. The frame portion 4 is in the shape of a roughly isosceles triangle with a vertex portion 2 (described later) on the lower side. The frame portion 4 has two oblique sides 1 and a base portion 3. The two oblique sides 1 are rod-shaped, have equal lengths, and are connected to each other at the vertex portions 2 at their lower ends. The base portion 3 is rod-shaped and connects the ends (upper ends) of the two oblique sides 1 opposite the vertices 2. The connecting portion between the oblique sides 1 and the base portion 3 is arc-shaped.

[0039] The see-through portion 5 has a plurality of holes formed therein. In this embodiment, the see-through portion 5 is mesh-like. More specifically, the see-through portion 5 is a lattice-like member in which rod-shaped members whose longitudinal direction is the vertical direction are arranged at regular intervals in the left-right direction, and rod-shaped members whose longitudinal direction is the left-right direction are also arranged at regular intervals in the up-down direction. The see-through portion 5 is disposed inside the frame portion 4 and is attached to the see-through portion 5 by welding or the like. The lattices of the see-through portion 5 are set at intervals so that combustible materials such as firewood do not fall out of the receiving portion 10, and in this embodiment, the distance between the lattices is 30 mm.

[0040] The fall suppression plate 6 is an isosceles triangular plate-shaped member with its apex facing downward. The fall suppression plate 6 is disposed inside the lower end of the frame 4 and attached to the frame 4 by welding. In this embodiment, the fall suppression plate 6 is attached to the obverse side (front side) of the frame 4. The surface of the fall suppression plate 6 is polished to a mirror finish.

[0041] As shown in Fig. 3, a rod-shaped first engagement protrusion 9a that protrudes outward and downward is attached by welding or the like to the middle portion of the oblique side portion 1. A rod-shaped third engagement protrusion 9b that protrudes downward is attached by welding or the like to the apex portion 2 of the receiving member 9. As shown in Fig. 3(B), the third engagement protrusion 9b protrudes outward from the connection portion with the apex portion 2.

[0042] As shown in Figures 1 and 2, the support leg 20 is rod-shaped and has an insertion hole 20a formed at its upper end. In this embodiment, the support leg 20 is cylindrical. A retaining hole 20c is formed and communicates with the support leg 20 at a position below the upper end. An engagement hole 20b is formed at a position slightly below the center of the support leg 20 in the longitudinal direction.

[0043] As shown in Figure 1, the vertices 2 of the three receiving members 9 are aligned in approximately the same position, and the oblique sides 1 of the receiving members 9 are arranged close to the oblique sides 1 of the adjacent receiving members 9, thereby forming a triangular pyramidal receiving portion 10 that opens upward. The first engagement protrusions 9a of adjacent receiving members 9 are adjacent to each other. Each of these two adjacent first engagement protrusions 9a is inserted into the insertion holes 20a of the corresponding support legs 20. In this way, the receiving portion 10, which is made up of three receiving members 9, is supported by the three support legs 20.

[0044] The ash pan 30 is disposed below the receiving portion 10 and receives ashes from combustible materials burned in the receiving portion 10. The ash pan 30 is composed of a receiving plate portion 31, three wall portions 32, and a connecting frame portion 33.

[0045] The receiving plate 31 is a plate-like shape with the apex of an equilateral triangle cut out, forming a roughly equilateral triangular plate. In this way, the receiving plate 31 has the apex of the equilateral triangle cut out, which prevents the user from being injured by the sharp apex of the equilateral triangle. A support hole 30c is formed in the center of the receiving plate 31 and communicates with the receiving plate 31. As shown in Figures 1 and 2, each third engagement protrusion 9b of each receiving member 9 is inserted into and supported by the support hole 30c.

[0046] 2, a reinforcing plate member 34 is attached by welding or the like to the center of the underside of the receiving plate portion 31. A circular hole is formed in the reinforcing plate member 34. The circular hole in the reinforcing plate member 34 is aligned with the support hole 30c, and the reinforcing plate member 34 is attached to the underside of the receiving plate portion 31. This reinforcing plate member 34 is intended to prevent damage or deformation of the support hole 30c and deformation of the receiving plate portion 31 around the support hole 30c when the three third engagement protrusions 9b are inserted into the support hole 30c.

[0047] 1, the outer edge of the receiving plate 31 is bent upward to form the wall 32. In other words, the wall 32 extends upward from the outer edge of the receiving plate 31.

[0048] The connecting frame 33 has an equilateral triangular frame shape. In this embodiment, the connecting frame 33 is formed by bending a wire rod into an equilateral triangle shape to form a ring. Each side of the connecting frame 33 is connected to the upper end of each wall portion 32 by welding. An insertion hole 30a is formed at each vertex of the connecting frame 33. In this embodiment, a wire rod 33a bent into a "L" shape is attached to the inside of each vertex of the connecting frame 33 by welding, thereby forming the insertion hole 30a. Each support leg 20 is inserted into each insertion hole 30a of the connecting frame 33.

[0049] 2, second engagement protrusions 30b that protrude inward and downward from the connection frame 33 are formed at each vertex of the connection frame 33. The second engagement protrusions 30b are inserted into and engaged with the engagement holes 20b of the support legs 20.

[0050] The locking member 40 connects the support leg 20 and the receiving member 9. As shown in Fig. 4, the locking member 40 is made up of a retaining member 41, a connecting member 42, and an engaging member 43. The retaining member 41 is made up of a first retaining member 41a and a second retaining member 41b.

[0051] The first retaining member 41a is in the shape of a round bar. The outer diameter of the first retaining member 41a is smaller than the diameter of the retaining hole 20c formed in the support leg 20. Therefore, the first retaining member 41a can be inserted into the retaining hole 20c.

[0052] The second retaining member 41b is ring-shaped and connected to the base end of the first retaining member 41a by welding or the like. The second retaining member 41b is composed of a first portion 41b1 and a second portion 41b2. The first portion 41b1 is annular and attached to the base end of the first retaining member 41a. The second portion 41b2 is U-shaped and has a width smaller than that of the first portion 41b1, and is connected to and integrated with the first portion 41b1. The widths of the first portion 41b1 and the second portion 41b2 are smaller than the diameter of the retaining hole 20c formed in the support leg 20. Therefore, the second retaining member 41b can be inserted into the retaining hole 20c.

[0053] In this embodiment, the connecting member 42 is a chain of oval ring-shaped members 42a made of metal and connected to each other. The ring member 42a of the distal connecting member 42 is connected to a longitudinal midpoint of the retaining member 41. Here, the longitudinal midpoint of the retaining member 41 is a position where the distance from the base end of the retaining member 41 is greater than the diameter of the retaining hole 20c. Specifically, the ring member 42a of the distal connecting member 42 is connected to the first portion 41b1 of the second retaining member 41b. The wire diameter of the ring member 42a is greater than the distance between the inner sides of the second portion 41b2, so that the ring member 42a of the distal connecting member 42 does not penetrate into the second portion 41b2.

[0054] The engaging member 43 detachably connects the annular member 42a on the base end side of the connecting member 42 and the see-through portion 5 of the receiving member 9. In this embodiment, the engaging member 43 is an elastic metal plate bent into a substantially oval shape, and one end of the metal plate is elastically deformed so that this portion can be opened or closed. The engaging member 43 is connected to the annular member 42a on the base end side of the connecting member 42.

[0055] As shown in FIG. 5, the engaging member 43 of each locking member 40 is connected to the see-through portion 5 of each receiving member 9. Each retaining member 41, consisting of a first retaining member 41a and a second retaining member 41b, is inserted into a retaining hole 20c of each support leg 20. As shown in FIG. 1, when the retaining member 41 is inserted into the retaining hole 20c, there is almost no slack in the connecting member 42. When the retaining member 41 attempts to come out of the retaining hole 20c, the first retaining member 41a and the second portion 41b2 get caught in the retaining hole 20c, preventing the retaining member 41 from coming out of the retaining hole 20c. This prevents the first engaging protrusion 9a from coming out of the insertion hole 20a.

[0056] As shown in Figure 6, the three receiving members 9, three support legs 20, and ash pan 30 that make up the fire pit 100 can be disassembled. The length of each side of the receiving member 9 and the length of the support legs 20 are shorter than the length of each side of the receiving plate portion 31 of the ash pan 30. Therefore, the disassembled receiving members 9 and support legs 20 can be stored in the ash pan 30, allowing for compact storage when the fire pit 100 is not in use. When using the fire pit 100, it can be assembled and used.

[0057] (Effects of this embodiment) The fire pit 100 has a receiving portion 10 and three support legs 20. The receiving portion 10 is composed of three receiving members 9. The receiving member 9 has a frame portion 4 with two oblique sides 1 of equal length, a vertex 2 where the two oblique sides 1 intersect, a base portion 3 connecting the ends opposite the vertices 2 of the two oblique sides 1, and a see-through portion 5 arranged inside the frame portion 4 and having multiple holes formed therein. The receiving portion 10 is configured in the shape of a triangular pyramid that opens upward, with the three receiving members 9 arranged in approximately the same position with the vertex 2 facing downward and each oblique side 1 arranged adjacent to the adjacent oblique side 1.

[0058] According to this, the receiving member 9 that receives the combustibles has a see-through section 5 with multiple holes formed therein, so when the fire pit 100 is viewed from the side, the burning combustibles can be seen through the see-through section 5. This makes it possible to provide a fire pit 100 that makes the burning combustibles look beautiful. Also, because the receiving section 10 is supported by three support legs 20, the fire pit 100 is stable and does not wobble, compared to a structure in which the receiving section 10 is supported by four support legs 20, even if the ground on which the fire pit 100 is placed is uneven.

[0059] The see-through section 5 is mesh-like.

[0060] According to this, since the see-through part 5 is mesh-like, when the fire pit 100 is viewed from the side, the burning combustible material can be more clearly seen through the see-through part 5. Therefore, it is possible to provide a fire pit 100 that makes the burning combustible material look even more beautiful.

[0061] In addition, the fire pit 100 further includes an ash pan 30 (connecting member) that is connected to the middle of each of the three support legs 20 and connects adjacent support legs 20 together.

[0062] According to this, the middle parts of three adjacent support legs 20 are connected by the ash pan 30, so that the fire pit 100 is prevented from being damaged due to the support legs 20 spreading apart.

[0063] The ash tray 30 also includes a receiving plate portion 31 disposed below the receiving portion 10.

[0064] This prevents combustible materials and ash from burning from falling to the ground. This prevents fires caused by combustible materials and ash from burning from falling to the ground. In addition, the fire pit 100 can be used even in places where open fires are prohibited.

[0065] The upper surface of the receiving plate portion 31 is mirror-finished.

[0066] In this way, the mirror-finished receiving plate 31 reflects the combustible material that has fallen onto the receiving plate 31 and is burning. This makes it possible to provide a fire pit 100 that makes the burning combustible material look even more beautiful.

[0067] The ash pan 30 also has a wall portion 32 extending upward from the outer edge of the receiving plate portion 31.

[0068] This prevents combustibles and ashes from burning the combustibles from falling from the receiving plate portion 31 onto the ground.

[0069] In addition, a fall prevention plate 6 is attached to the inside of the lower part of the frame part 4.

[0070] This prevents combustible materials from falling from the receiving portion 10.

[0071] The outer surface of the fall prevention plate 6 is mirror-finished.

[0072] In this way, the mirror-finished fall prevention plate 6 reflects the combustibles that have fallen onto the receiving plate 31 and are burning. This makes it possible to provide a fire pit 100 that makes the burning combustibles look even more beautiful.

[0073] An insertion hole 20a is formed in the upper end of each support leg 20, and a first engagement protrusion 9a that protrudes outward is formed in the middle of each of the two oblique sides 1 of each receiving plate portion 31. Three insertion holes 30a are formed in the ash pan 30. The first engagement protrusions 9a are inserted into the insertion holes 30a of each support leg 20, and the middle portions of each support leg 20 are inserted into the insertion holes 30a for support, and the three receiving members 9, three support legs 20, and ash pan 30 are configured to be assembleable and disassembleable.

[0074] As a result, as shown in Figure 6, when the fire pit 100 is not in use, it can be disassembled into three receiving members 9, three support legs 20, and an ash pan 30, allowing it to be stored compactly.

[0075] An engagement hole 20b is formed in the middle of each of the three support legs 20. A second engagement protrusion 30b that protrudes inward is formed in the portion of the ash pan 30 where the insertion hole 30a is formed. The second engagement protrusion 30b is inserted into and engages with the engagement hole 20b.

[0076] According to this, the second engaging protrusion 30b is inserted into and engaged with the engaging hole 20b, thereby connecting the support leg 20 to the ash pan 30. As a result, the support leg 20 and the ash pan 30 are prevented from moving relative to each other, the support leg 20 is firmly connected by the ash pan 30, and the fire pit 100 is stabilized.

[0077] Further, one support hole 30c is formed in the ash tray 30. Third engagement protrusions 9b protruding downward are formed at the apex 2 of the receiving member 9. The three third engagement protrusions 9b are inserted into and engaged with the support hole 30c.

[0078] According to this, the three third engaging protrusions 9b are inserted into and engaged with one support hole 30c, thereby preventing the lower ends of the three receiving members 9 from spreading open and suppressing the spilling of combustible materials from the bottom of the receiving portion 10.

[0079] In addition, a locking hole 20c is formed in each support leg 20. The fire pit 100 further has three locking members 40, each of which includes a locking member 41 that can be inserted into the locking hole 20c and a connecting member 42 that connects the locking member 41 to the receiving member 9. Each of the three locking members 40 is connected to a different receiving member 9, and the locking member 41 is inserted into the locking hole 20c to prevent the first engagement protrusions 9a from coming out of the corresponding insertion holes 20a.

[0080] This prevents the first engagement protrusion 9a from coming out of the insertion hole 20a, and prevents the first engagement protrusion 9a from coming out of the insertion hole 20a when the fire pit 100 is in use, thereby preventing the fire pit 100 from being disassembled.

[0081] The connecting member 42 is connected to the retaining member 41 at a midpoint in the longitudinal direction.

[0082] According to this, when the retaining member 41 tries to come out of the retaining hole 20c, the retaining member 41 gets caught in the retaining hole 20c, and the retaining member 41 is prevented from coming out of the retaining hole 20c. This further prevents the first engaging protrusion 9a from coming out of the insertion hole 20a.

[0083] The retaining member 41 includes a rod-shaped first retaining member 41a and an annular second retaining member 41b connected to the base end of the first retaining member 41a. The second retaining member 41b is U-shaped and has a second portion 41b2 whose inner width is smaller than the wire diameter of the connecting member 42.

[0084] This allows for a structure in which, when the anti-slip member 41 tries to come out of the anti-slip hole 20c, the first anti-slip member 41a and the second part 41b2 get caught in the anti-slip hole 20c, preventing the anti-slip member 41 from coming out of the anti-slip hole 20c.
