Description

[Technical Field]

[0001] The present invention relates to a barbecue grill, and more particularly to a foldable barbecue grill. [Background technology]

[0002] Foldable barbecue grills have been proposed. For example, Patent Document 1 discloses a barbecue grill in which a front wall, a rear wall, a first side wall, and a second side wall are rotatably attached to a frame. In the barbecue grill of Patent Document 1, when in use, the front wall, the rear wall, the first side wall, and the second side wall are rotated around the frame as a starting point, opened, and fixed. This achieves the unfolded state. After use, the front wall, the rear wall, the first side wall, and the second side wall are rotated in the opposite direction to when they were opened, so that they overlap each other. This achieves the folded state. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3215288 Summary of the Invention [Problem to be solved by the invention]

[0004] The folding barbecue grill in Patent Document 1 has the problem of being difficult to open and close. When switching from a folded state to an unfolded state, each wall must be rotated to an appropriate angle to unfold it, and then fitted and secured together. Barbecue grills are used at high temperatures. As a result, distortions can occur in the frame and each wall over time, making it difficult to unfold the grill or to fit the required components together.

[0005] The barbecue grill is switched from the unfolded state to the folded state after use. During use, the barbecue grill becomes hot. It takes time for the barbecue grill to cool down to room temperature. Due to time constraints, people may put away the barbecue grill after use without allowing it to cool down sufficiently. Folding the barbecue grill in Patent Document 1 requires delicate work of disengaging each wall and folding the walls one by one. This work is done by hand. Therefore, the folding barbecue grill in Patent Document 1 poses a risk of burns and other injuries.

[0006] Furthermore, after use, a lot of ash adheres to the barbecue grill. Most of the ash adheres to the walls surrounding the area where the charcoal is placed. Therefore, with the folding barbecue grill of Patent Document 1, hands and clothes are easily soiled when folding each wall.

[0007] As described above, conventional folding barbecue grills are not easy to open and close. Therefore, an object of the present invention is to provide a folding barbecue grill that is easy to open and close. [Means for solving the problem]

[0011] (Expanded and collapsed) An embodiment of the barbecue grill 1 of the present invention will be described with reference to the drawings. The barbecue grill 1 is foldable. When the barbecue grill 1 is not in use and is folded, it is called the folded state. When the barbecue grill 1 is opened from the folded state to be used, it is called the unfolded state.

[0012] FIG. 1 is a diagram showing the barbecue grill 1 in an unfolded state. FIG. 2 is a diagram showing the barbecue grill 1 in a folded state. As shown in FIG. 1, the barbecue grill 1 of this embodiment has a substantially triangular prism shape when unfolded. As shown in FIG. 2, the barbecue grill 1 of this embodiment has a substantially rectangular parallelepiped shape when folded. FIG. 4 is a diagram showing the barbecue grill 1 in a state approaching the unfolded state from the folded state. FIG. 5 is a diagram showing the barbecue grill 1 in a state approaching the folded state from the unfolded state. The configuration of the barbecue grill 1 will be explained below mainly with reference to FIG. 1 and FIG. 2.

[0013] (in each direction) The double-headed arrows shown in Figure 1 and elsewhere indicate the width direction 101, depth direction 102, and height direction 103, respectively. These directions are perpendicular to one another. The depth direction 102 is the direction in which the dimensions of the barbecue grill 1 change between the folded state and the unfolded state. The height direction 103 is the direction that is approximately vertical when the barbecue grill 1 is in use. The width direction 101 is a direction that is perpendicular to the depth direction 102 and the height direction 103. These directions are also shown in figures other than Figure 1.

[0014] In a direction parallel to the height direction 103, the direction indicated by the arrow 1031 in Fig. 1 is the downward direction 1031, and the direction indicated by the arrow 1032 is the upward direction 1032. In addition, in the barbecue grill 1, the part indicated by the arrow 1031 in Fig. 1 is called the lower part 1131, and the part indicated by the arrow 1032 is called the upper part 1132.

[0015] (Barbecue stove configuration) As shown in Figure 1, the barbecue grill 1 includes a first main panel 11, a second main panel 12, a first side panel 31, and a second side panel 32. The first main panel 11, the second main panel 12, the first side panel 31, and the second side panel 32 are all plate-shaped members made of metal. The first main panel 11, the second main panel 12, the first side panel 31, and the second side panel 32 are rotatably connected via connecting parts, which will be described later.

[0016] (First main panel and second main panel) The first main panel 11 and the second main panel 12 are both plate-like members having a substantially rectangular parallelepiped shape. The first main panel 11 and the second main panel 12 are arranged to face each other in the depth direction 102. The first main panel 11 and the second main panel 12 have substantially the same shape. Below, the main panels will be described using the first main panel 11 as an example. Unless otherwise specified, the matters described for the first main panel 11 also apply to the second main panel 12.

[0017] (outer main surface) 2, the first main panel 11 has a first outer major surface 111 that is parallel to the width direction 101 and the height direction 103 in the folded state and has a substantially rectangular shape. Similarly, the second main panel 12 has a second outer major surface 121.

[0018] (inner main surface) 1, the surface of the first main panel 11 opposite the first outer main surface 111 is referred to as the first inner main surface 112. Similarly, the surface of the second main panel 12 opposite the second outer main surface 121 is referred to as the second inner main surface 122. The first inner main surface 112 and the second inner main surface 122 both face the interior 3 of the barbecue grill 1 and are opposite each other.

[0019] (Main and side edges) The main edges and side edges of the main panel will now be described. As shown in FIG. 1 , of the edge edges parallel to the width direction 101 on the first outer main surface 111 and the first inner main surface 112, the edge positioned downward 1031 in the height direction 103 is referred to as the first main edge 131. Of the edge edges parallel to the width direction 101 on the first outer main surface 111 and the first inner main surface 112, the edge positioned upward 1032 in the height direction 103 is referred to as the second main edge 132. Of the edge edges parallel to the height direction 103 on the first outer main surface 111 and the first inner main surface 112, one edge is referred to as the first side edge 141, and the other edge is referred to as the second side edge 142.

[0020] The same applies to the second main panel 12. The main edges and side edges of the second outer main surface 121 and the second inner main surface 122 are referred to as a third main edge 133, a fourth main edge 134, a third side edge 143, and a fourth side edge 144, respectively.

[0021] (Side wall) The side wall portions of the main panels will now be described. The main panels include side wall portions. The side wall portions refer to portions that extend from the sides of the main panels in the depth direction 102. First main panel 11 and second main panel 12 each include two side wall portions.

[0022] As shown in Figures 1 and 2, the side wall portion extending from the first side edge 141 is called the first side wall portion 151, the side wall portion extending from the second side edge 142 is called the second side wall portion 152, the side wall portion extending from the third side edge 143 is called the third side wall portion 153, and the side wall portion extending from the fourth side edge 144 is called the fourth side wall portion 154.

[0023] The side wall portions will be described using the first side wall portion 151 as an example. The first side wall portion 151 extends a predetermined length from the first side edge 141 in the depth direction 102. The first side wall portion 151 has a substantially rectangular shape, and its long side extends along the first side edge 141.

[0024] (Side wall side) First side wall 151 has an end edge that is approximately parallel to first side edge 141. This end edge is referred to as a side wall edge. Specifically, the side wall edge of first side wall 151 is referred to as a first side wall edge 161, the side wall edge of second side wall 152 is referred to as a second side wall edge 162, the side wall edge of third side wall 153 is referred to as a third side wall edge 163, and the side wall edge of fourth side wall 154 is referred to as a fourth side wall edge 164.

[0025] (Main side of side wall) The first side wall portion 151 has an end edge continuing from the first main edge 131. This end edge is referred to as the first side wall portion main edge 171. Similarly, the end edge of the second side wall portion 152 continuing from the first main edge 131 is referred to as the second side wall portion main edge 172. Furthermore, the end edge of the third side wall portion 153 continuing from the third main edge 133 is referred to as the third side wall portion main edge 173, and the end edge of the fourth side wall portion 154 continuing from the third main edge 133 is referred to as the fourth side wall portion main edge 174.

[0026] (Connection between the first main panel and the second main panel) The following describes the connection between the first main panel 11 and the second main panel 12. The first main panel 11 and the second main panel 12 are connected at the first main side 131 of the first main panel 11 and the third main side 133 of the second main panel 12.

[0027] (Main edge) The portion of the first main panel 11 near the first main edge 131 is referred to as the first main edge portion 181. The first main edge portion 181 includes a portion near the first side wall main edge 171 that is continuous with the first main edge 131 and a portion near the second side wall main edge 172 that is continuous with the first main edge 131. Similarly, the portion of the second main panel 12 near the third main edge 133 is referred to as the second main edge portion 182. The second main edge portion 182 includes a portion near the third side wall main edge 173 that is continuous with the third main edge 133 and a portion near the fourth side wall main edge 174 that is continuous with the fourth main edge 134.

[0028] The connection between the first main panel 11 and the second main panel 12 at the first main edge 131 side of the first main panel 11 and the third main edge 133 side of the second main panel 12 means that the first main panel 11 and the second main panel 12 are connected at the first main edge portion 181 and the second main edge portion 182. The connection between the first main panel 11 and the second main panel 12 is made via the connection portion 200.

[0029] (Connection) The connecting portion 200 will be described with reference to FIG. 3 in addition to FIGS. 1 and 2. FIG. 3 is an enlarged view of the enclosed area 90 in FIG. 1. The connecting portion 200 is a portion that rotatably connects the first main panel 11 and the second main panel 12. The connecting portion 200 is provided at each end of the main panel in the width direction 101. In the following description, the connecting portion 200 provided at one end will be used as an example. A connecting portion 200 similar to the connecting portion 200 described below is also provided at the other end. One connecting portion 200 includes two rivets, two rivet holes, and one center guide. These will be described in order below.

[0030] (rivet holes) The rivet holes are through holes formed in the first main panel 11 or the second main panel 12. As shown in FIG. 3 , of the two rivet holes, one rivet hole is provided in the first main panel 11, and the other rivet hole is provided in the second main panel 12. The rivet hole provided in the first main panel 11 is called the first rivet hole 211. The rivet hole provided in the second main panel 12 is called the second rivet hole 212.

[0031] More specifically, rivet holes are provided in the side wall portions of each main panel. As shown in Fig. 3, first rivet holes 211 are provided in the vicinity of first side wall main edge 171 of first side wall portion 151. That is, first rivet holes 211 are provided in first main edge portion 181. On the other hand, second rivet holes 212 are provided in the vicinity of third side wall main edge 173 of third side wall portion 153. That is, second rivet holes 212 are provided in second main edge portion 182.

[0032] (Center guide) The center guide 205 is a plate-shaped member that is sandwiched together with the main panels by rivets, thereby rotatably fixing the first main panel 11 and the second main panel 12 together. The center guide 205 is located at a position corresponding to the rivet holes in the interior 3 of the barbecue grill 1. The center guide 205 straddles the first main panel 11 and the second main panel 12 in the depth direction 102 and is located on the interior 3 side of the barbecue grill 1 of the first main panel 11 and the second main panel 12. More specifically, the center guide 205 straddles the first side wall portion 151 and the third side wall portion 153 and is located on the interior 3 side of the barbecue grill 1 of the first side wall portion 151 and the third side wall portion 153.

[0033] (Riveted) The rivets 206 are through holes formed in the center guide 205. The rivets 206 are formed so as to extend in the depth direction 102 when the center guide 205 is placed inside the interior 3 of the barbecue grill 1.

[0034] (rivet) One rivet is provided in each rivet hole. As shown in FIG. 1, the rivet provided in the first rivet hole 211 (shown in FIG. 3) is called the first rivet 201. The rivet provided in the second rivet hole 212 (shown in FIG. 3) is called the second rivet 202. Note that rivets are not shown in FIG. 3. The first rivet 201 is fastened by passing through the first rivet hole 211 and the rivet stop 206 of the center guide 205. The second rivet 202 is fastened by passing through the second rivet hole 212 and the rivet stop 206 of the center guide 205.

[0035] At the connection portion 200, the first main panel 11 and the second main panel 12 can be rotatably fixed by fastening both ends of the rivet through the rivet holes in each of the first main panel 11 and the second main panel 12 and the rivet stop 206 of the center guide 205.

[0036] The barbecue grill 1 can be switched between the folded state and the unfolded state by rotating the first main panel 11 and the second main panel 12 via the connecting part 200.

[0037] (Rotation stop end) The transition from the folded state to the unfolded state will now be described. The degree of unfolding of the first main panel 11 and the second main panel 12 in the unfolded state can be determined, for example, by the first main panel 11 and the second main panel 12 unfolding and a portion of the first main panel 11 coming into contact with a portion of the second main panel 12. In other words, a state is created in which further unfolding is not possible when a portion of the first main panel 11 comes into contact with a portion of the second main panel 12. This state is called the unfolded state. The portion where the first main panel 11 and the second main panel 12 come into contact is called the rotation stop end.

[0038] 3, a first rotation stop end 191 is provided on the first side wall portion 151. A second rotation stop end 192 is provided on the third side wall portion 153. The first rotation stop end 191 is the rotation stop end on the first main panel 11 side, and the second rotation stop end 192 is the rotation stop end on the second main panel 12 side.

[0039] The rotation stop end on the first main panel 11 side is formed on an edge of the side wall portion of the first main panel 11 that faces the side wall portion of the second main panel 12. Similarly, the rotation stop end on the second main panel 12 side is formed on an edge of the side wall portion of the second main panel 12 that faces the side wall portion of the first main panel 11. FIG. 3 shows a first rotation stop end 191 formed on the first side wall portion 151 and a second rotation stop end 192 formed on the third side wall portion 153. The contact between the first rotation stop end 191 and the second rotation stop end 192 stops the first main panel 11 and the second main panel 12 from unfolding.

[0040] In the unfolded state, the direction in which first rotation stop end 191 and the direction in which second rotation stop end 192 extend are both along height direction 103. As shown in FIG. 1 , the angle formed between first side edge 141 and third side edge 143 in the unfolded state is defined as angle 92. Angle 92 can be, for example, between 30 degrees and 90 degrees.

[0041] (Side panel) The side panels will be described with reference to Figure 1. The side panels are members that form the sides of the barbecue grill 1 in the width direction 101 when it is unfolded. The side panels include a first side panel 31 and a second side panel 32. Of the two sides of the barbecue grill 1, one side is referred to as the first side 5 and the other side is referred to as the second side 6. The first side panel 31 is the side panel that forms the first side 5. The second side panel 32 is the side panel that forms the second side 6.

[0042] The sides of the barbecue grill 1 of this embodiment are mainly composed of the side walls of the main panel and the side panels. Specifically, the first side 5 is composed of the first side wall 151, the third side wall 153, and the first side panel 31. Similarly, the second side 6 is composed of the second side wall 152, the fourth side wall 154, and the second side panel 32.

[0043] The side surface of the barbecue grill 1 has a substantially triangular shape, and accordingly, the side panel also has a substantially triangular shape.

[0044] (Sub-panel) Each side panel includes multiple sub-panels. Specifically, the first side panel 31 includes a first sub-panel 301 and a third sub-panel 303. The second side panel 32 includes a second sub-panel 302 and a fourth sub-panel 304. Below, the sub-panels and other components will be described mainly using the first side surface 5 as an example. The following description also applies to the second side surface 6.

[0045] The first sub-panel 301 and the third sub-panel 303 have a shape obtained by dividing the first side panel 31 into two along the height direction 103 .

[0046] (Folding hinge) Two sub-panels that make up the same side panel are rotatably connected by hinges. The hinge connecting the first sub-panel 301 and the third sub-panel 303 is called the first folding hinge. The hinge connecting the second sub-panel 302 and the fourth sub-panel 304 is called the second folding hinge.

[0047] As shown in Figures 1 and 4, in the unfolded state, the two sub-panels are positioned on approximately the same plane. In other words, the angle between the two sub-panels is close to 180 degrees. When folding the barbecue grill 1 from the unfolded state to the folded state, the folding hinge moves toward the interior 3 of the barbecue grill 1, as shown in Figure 5. As a result, the two sub-panels connected via the folding hinge are folded so that the angle between them approaches 0 degrees.

[0048] (Main body hinge) The sub-panel and main panel are rotatably connected by a hinge. More specifically, the sub-panel and the side wall of the main panel are connected by a hinge. The hinge connecting the sub-panel and the main panel is called the main body hinge.

[0049] 1, the main body hinge connecting the first sub-panel 301 and the first side wall portion 151 is called a first main body hinge 321. Similarly, the main body hinge connecting the second sub-panel 302 and the second side wall portion 152 is called a second main body hinge 322, the main body hinge connecting the third sub-panel 303 and the third side wall portion 153 is called a third main body hinge 323, and the main body hinge connecting the fourth sub-panel 304 and the fourth side wall portion 154 is called a fourth main body hinge 324.

[0050] The main body hinges are formed to extend in a direction along the corresponding side edge. Taking first main body hinge 321 as an example, first main body hinge 321 extends in a direction along first side edge 141, which is the end edge of first side wall portion 151 connected by first main body hinge 321.

[0051] As shown in Figures 1 and 4, in the unfolded state, the sub-panel and the side wall portion connected to the sub-panel are positioned on approximately the same plane. In other words, the angle between the sub-panel and the side wall portion is close to 180 degrees. Also, as described above, in the unfolded state, the angle between the two sub-panels is close to 180 degrees. As a result, in the unfolded state, the two sub-panels and the two side wall portions forming one side surface are positioned on approximately the same plane. Taking the first side surface 5 as an example, the first side wall portion 151, the first sub-panel 301, the third sub-panel 303, and the third side wall portion 153 are positioned on approximately the same plane.

[0052] When folding the barbecue grill 1 from the unfolded state to the folded state, the two main body hinges on the same side move toward each other in the depth direction 102, as shown in Figure 5. As this movement occurs, the sub-panel rotates toward the interior 3 of the barbecue grill 1, with the main body hinge as the axis of rotation. In the folded state, the two sub-panels on the same side are close to each other, and the angle they form approaches 0 degrees. In the folded state, the dimension of the barbecue grill 1 in the depth direction 102 is approximately the same as in the height direction 103. In other words, the external shape of the barbecue grill 1 is approximately rectangular.

[0053] Specifically, in the folded state, the first main panel 11, the first sub-panel 301, the third sub-panel 303, and the second main panel 12 overlap, and the first main panel 11, the second sub-panel 302, the fourth sub-panel 304, and the second main panel 12 overlap. In addition, in the folded state, the outer surfaces of the first sub-panel 301 and the third sub-panel 303 face each other, and the outer surfaces of the second sub-panel 302 and the fourth sub-panel 304 face each other. Here, the outer surface refers to the surface opposite the surface that faces the interior 3 of the barbecue grill 1 in the unfolded state.

[0054] When switching from the unfolded state to the folded state, the unfolded state can be switched to the folded state, for example, by the first main panel 11 and the second main panel 12 coming into contact above in the height direction 103.

[0055] As described above, the barbecue grill 1 of this embodiment can provide a folding barbecue grill that can be opened and closed simply by opening and closing the main panel. Furthermore, the barbecue grill 1 of this embodiment can provide a folding barbecue grill in which two sides can be closed in the unfolded state without any special operation.

[0056] (Deployment state fixing member) The unfolded state fixing member 70 will be described with reference to Figure 1. The unfolded state fixing member 70 is a member that prevents the barbecue grill 1 from being unintentionally folded when in the unfolded state. The unfolded state fixing member 70 is provided on the first side surface 5 and the second side surface 6. The unfolded state fixing member 70 will be described below using the unfolded state fixing member 70 provided on the first side surface 5 as an example. The unfolded state fixing member 70 provided on the second side surface 6 can also be similar to the unfolded state fixing member 70 described below.

[0057] The unfolded state fixing member 70 includes an arm member 71 and an arm receiving portion 72. The arm member 71 is an elongated member that determines the dimension of the barbecue grill 1 in the depth direction 102 when it is in the unfolded state. The arm member 71 is provided on the upper portion 1132 of the third side wall portion 153. The arm receiving portion 72 is a portion to which one end of the arm member 71 is fixed. The arm receiving portion 72 is provided on the upper portion 1132 of the first side wall portion 151.

[0058] The arm member 71 includes an extension portion 711, a rotating portion 712, and a fitting portion 713. The extension portion 711 is an elongated member having a length corresponding to the dimension in the depth direction 102 from the third side wall portion 153 to the first side wall portion 151 in the unfolded state. The rotating portion 712 is a member that rotatably fixes one end of the extension portion 711 to the third side wall portion 153. The fitting portion 713 is provided at the other end of the extension portion 711, and is a portion that is fitted into a fitting hole 721 of the arm receiver 72, which will be described below, thereby fixing the other end of the extension portion 711 to the arm receiver 72.

[0059] The arm receiving portion 72 includes a fitting hole 721. The fitting hole 721 is a portion into which the fitting portion 713 of the arm member 71 is fitted.

[0060] By fitting the fitting portion 713 into the fitting receiving hole 721 and fixing the arm member 71 to the arm receiving portion 72, the dimension of the barbecue grill 1 in the depth direction 102 is fixed. Therefore, it is possible to prevent the barbecue grill 1 from being folded up unintentionally when in the unfolded state.

[0061] In addition, the deployed state fixing member 70 is not limited to being provided on both the first side surface 5 and the second side surface 6 as described above, but may be provided on, for example, either the first side surface 5 or the second side surface 6.

[0062] (Example of usage) An example of how the barbecue grill 1 is used will be described with reference to Figure 6. Figure 6 shows the barbecue grill 1 installed on the frame body 1000. As shown in Figures 6 and 5, the barbecue grill 1 is provided with a handle 7. Furthermore, as shown in Figure 1, a handle recess 8 is formed between the handle 7 and the main panel. By fitting the pipe 1001 of the frame body 1000 into the handle recess 8 of the barbecue grill 1, the barbecue grill 1 can be easily and stably installed on the frame body 1000.

[0063] (Grate material) The grate member 80 and the sliding screen 40 will be described with reference to Figure 7. Figure 7 is a perspective view of the barbecue grill 1 seen from above. As shown in Figure 7, the barbecue grill 1 is equipped with a grate member 80. The grate member 80 is a plate on which a heat source such as charcoal is placed. The grate member 80 is installed inside the barbecue grill 1 when it is in use. The grate member 80 is a plate-shaped member with multiple, elongated openings formed in succession. These openings are called grate openings 82. When the barbecue grill 1 is not in use, the grate member 80 can also be stored between the first main panel 11 and the second main panel 12 in the folded state.

[0064] (Slide net) As shown in Figures 6 and 7, the barbecue grill 1 is equipped with a sliding grid 40. The sliding grid 40 is a plate on which ingredients, pots, etc. to be heated on the barbecue grill 1 can be placed. The sliding grid 40 is installed on the upper part 1132 of the barbecue grill 1. The sliding grid 40 is a plate-shaped member with multiple, elongated openings formed in succession. These openings are called grid openings 41. When the barbecue grill 1 is not in use, the sliding grid 40 can also be stored between the first main panel 11 and the second main panel 12 in the folded state, similar to the fire grate member 80.

[0065] (Slide net slide) The sliding net 40 can be slid while ingredients or pots are placed on the sliding net 40. The sliding net 40 can be slid by, for example, fitting rails provided on the main panel into rail receivers provided on the sliding net 40.

[0066] (Rail support part) 7, rail receiving portions 42 are provided on both sides of the sliding net 40 in the depth direction 102, along the width direction 101. The rail receiving portions 42 have a shape in which the ends of the sliding net 40 are bent to have recesses.

[0067] (rail) On the other hand, rails 43 are formed on the main edges of the main panels as shown in Figures 7 and 1. Specifically, rails 43 are provided on the second main edge 132 of the first main panel 11 and the fourth main edge 134 of the second main panel 12.

[0068] (Upper extension) Note that "rail 43 is provided on the main side" does not necessarily mean that rail 43 is provided directly on the main side. "rail 43 is provided on the main side" also includes a configuration in which rail 43 is provided via an extension portion that continues from the main side. In the example shown in Fig. 1, rail 43 is provided on the upper side via an upper side extension portion. This will be explained in detail below.

[0069] 1, the first main panel 11 includes a first upper edge extension 431 extending from the second main edge 132 in a direction opposite to the first main edge 131. Similarly, the second main panel 12 includes a second upper edge extension 432 extending from the fourth main edge 134 in a direction opposite to the third main edge 133. The rails 43 are provided on the end edge of the first upper edge extension 431 facing the second main edge 132, and on the end edge of the second upper edge extension 432 facing the fourth main edge 134.

[0070] Rail 43 is processed into a shape such that, for example, the end of the main panel fits into rail receiving portion 42 of sliding net 40. Rail 43 also extends along width direction 101. In the example shown in Fig. 7 and Fig. 1, rail 43 has a shape in which the end of the main panel is bent outward.

[0071] 1, the first upper side extension portion 431 and the second upper side extension portion 432 extend in the height direction 103 in the unfolded state. The rails 43 extend from each upper side extension portion toward the outside of the barbecue grill 1 in the depth direction 102.

[0072] The shapes of the rail receiving portion 42 and the rail 43 are not limited to the above-mentioned examples. The configurations of the rail receiving portion 42 and the rail 43 are not particularly limited as long as they fit together and the sliding net 40 is slidable.

[0073] The barbecue grill 1 of this embodiment is equipped with a slidable sliding grill 40, which makes it easy to remove ingredients from the fire and add charcoal. There is no particular limit to the number of sliding grills 40 that the barbecue grill 1 is equipped with. For example, the top 1132 of the barbecue grill 1 may be covered with one sliding grill 40, or multiple sliding grills 40 may be used to cover the top 1132 of the barbecue grill 1.

[0074] (charcoal discard) The lower part 1131 of the barbecue grill 1, i.e., the bottom of the barbecue grill 1, will be described with reference to Figures 4 and 5. As shown in Figure 4, the lower part 1131 of the barbecue grill 1 of this embodiment is closed when the barbecue grill 1 is in use, i.e., in the deployed state. This prevents charcoal from falling from the lower part 1131 when the barbecue grill 1 is in use.

[0075] In contrast, when the barbecue grill 1 is finished being used and is folded up, the bottom 1131 of the barbecue grill 1 opens, as shown in Figure 5. Therefore, when it is time to discard the charcoal after using the barbecue grill 1, the charcoal and ashes can be disposed of simply by closing the barbecue grill 1 at a charcoal disposal area, without having to turn the barbecue grill 1 over or pick up the charcoal inside the barbecue grill 1.

[0076] (Bottom extension) 4, the first main panel 11 includes a first bottom extension 501 extending from the first main edge 131 in the opposite direction to the second main edge 132. Similarly, the second main panel 12 includes a second bottom extension 502 extending from the third main edge 133 in the opposite direction to the fourth main edge 134. The end edge of the first bottom extension 501 facing the first main edge 131 is referred to as the first bottom edge 511. Similarly, the end edge of the second bottom extension 502 facing the third main edge 133 is referred to as the second bottom edge 512.

[0077] In the unfolded state, as shown in Figure 4, first bottom edge 511 and second bottom edge 512 are in contact with each other. This closes lower part 1131 of barbecue grill 1, as shown by arrow 551. This prevents charcoal from falling from lower part 1131 when barbecue grill 1 is in use.

[0078] On the other hand, in the folded state, as shown in Figure 5, the first bottom edge 511 and the second bottom edge 512 are not in contact. A gap is formed between the first bottom edge 511 and the second bottom edge 512. In other words, as shown by arrow 552, the lower part 1131 of the barbecue grill 1 is open. Therefore, when discarding charcoal, by folding the barbecue grill 1, the charcoal and ashes can be easily discarded from the lower part 1131.

[0079] (Adjusting the amount of air) Adjusting the amount of air in the barbecue grill 1 will be described with reference to Figure 8. Figure 8 is a perspective view of the barbecue grill 1 as seen from the depth direction 102. In the barbecue grill 1 of this embodiment, the amount of air flowing into the barbecue grill 1 can be adjusted and the heat can be adjusted by opening and closing the air holes provided in the bottom 1131 of the barbecue grill 1.

[0080] (Air adjustment section) The part of the barbecue grill 1 that adjusts the amount of air is called the air adjustment unit 60. The air adjustment unit 60 includes a slit 62 provided in the main panel, a slide member 66 that can slide at a position corresponding to the slit 62 on the surface of the main panel, and a guide 64 that determines the position to which the slide member 66 slides. The following description will be given using the first main panel 11 as an example. Note that the second main panel 12 also has an air adjustment unit 60 similar to the air adjustment unit 60 described below.

[0081] (Slit part) The slit portion 62 is provided along the width direction 101 in the lower portion 1131 of the first main panel 11, specifically near the first main edge 131. The slit portion 62 includes a slit opening 621 and a slit shielding portion 622. The slit opening 621 is a through-hole provided in the first main panel 11. Air can enter and exit the interior of the barbecue grill 1 through the slit opening 621. The slit opening 621 may have a rectangular shape that is long in the height direction 103. A plurality of slit openings 621 are provided in the width direction 101. The slit openings 621 are also called first openings, in contrast to slide openings 661, which are second openings described later. The portion between adjacent slit openings 621 is called a slit shielding portion 622.

[0082] (Sliding member) The sliding member 66 is disposed on the outer side of the first main panel 11 at a position corresponding to the slit portion 62. The sliding member 66 can slide in the width direction 101 along the slit portion 62. The sliding member 66 slides while being restricted by a guide portion 64 provided on the first main panel 11. The guide portion 64 can be a frame that covers at least a part of the edge of the sliding member 66. In the example shown in FIG. 8 , the guide portions 64 are provided above and below the slit portion 62 along the width direction 101.

[0083] The slide member 66 has an opening and a shielding portion at positions corresponding to the slit opening 621 and slit shielding portion 622 of the slit portion 62. The opening is a through hole provided in the slide member 66. The opening provided in the slide member 66 is called a slide opening 661. A plurality of slide openings 661 are provided in succession. The slide openings 661 are also called second openings in contrast to the slit openings 621, which are the first openings. The shielding portion is the portion between adjacent slide openings 661. The shielding portion provided in the slide member 66 is called a slide shielding portion 662. The slide shielding portion 662 can also be said to be a portion of the slide member 66 where the slide openings 661 are not formed.

[0084] The correspondence between the slide opening 661 and slide shielding portion 662 of the slide member 66 and the slit opening 621 and slit shielding portion 622 of the slit portion 62 means that the following state can be realized depending on the relative positional relationship between the slide member 66 and the slit portion 62.

[0085] Fully open state: A state in which the entire slit opening 621 and the slide opening 661 overlap, and the slit opening 621 is not blocked by the slide member 66.

[0086] Fully closed state: The entire slit opening 621 and the sliding shielding portion 662 overlap, and the entire slit opening 621 is blocked by the sliding member 66.

[0087] Partially closed state: A state in which a part of the slit opening 621 overlaps with the sliding shielding portion 662 and a part of the slit opening 621 is blocked by the sliding member 66.

[0088] The heating power can be adjusted by adjusting the amount of air, for example, by switching between a fully open state, a fully closed state, and a partially closed state, and by adjusting the proportion of the slit opening 621 that is blocked by the slide member 66 in the partially closed state.

[0089] In the barbecue grill 1 of this embodiment, as shown in Figure 1, the first side surface 5 is blocked by the first side panel 31 and the like, and the second side surface 6 is blocked by the second side panel 32 and the like. Therefore, the inflow of air from the outside into the interior 3 of the barbecue grill 1 is limited to inflow through the slit portion 62, except for inflow through the upper portion 1132. Therefore, by adjusting the opening state of the slit portion 62 with the sliding member 66, the heat of the charcoal can be easily and accurately adjusted.

[0090] The air adjustment unit 60 is not limited to being provided on both the first main panel 11 and the second main panel 12. The air adjustment unit 60 may be provided on either the first main panel 11 or the second main panel 12.
