The stove of the present invention has the above-mentioned folding structure, and the part is a fire bed.

According to the present invention, it is possible to provide a folding structure capable of easily switching between a housed state and a used state, and a stove having this folding structure.

It is a perspective view which shows the outline of a stove. It is a perspective view of the stove in the housed state that the surface of the frame faces upward. It is a perspective view of the stove in the housed state that the back surface of the frame faces upward. It is sectional drawing in the XZ plane of a stove. It is sectional drawing in the YY plane of a stove.

As shown in FIGS. 1 and 2, the stove 2 has a rectangular frame 10, a grill 20 that can be attached to and detached from the frame 10, a plate-shaped fire bed 30 (first component), and a plate. It is provided with a heat-shielding plate 40 (second component) and a switching unit 50. Hereinafter, for convenience of explanation, the direction of the long side of the frame body 10 is the X direction, the direction of the short side of the frame body 10 is the Y direction, and the thickness direction of the frame body 10 is the Z direction.

The grill 20, the fire bed 30, and the heat shield plate 40 are each formed in a rectangular shape, and the direction of the long side is the X direction and the direction of the short side is the Y direction. Further, the fire bed 30 is formed with holes at predetermined positions.

The switching unit 50 has an external position (FIG. 1) in which the fire bed 30 and the heat shield plate 40 are located outside the frame body 10 and an inside in which the fire floor 30 and the heat shield plate 40 are located in the internal space 10X of the frame body 10. It can be switched between the positions (FIGS. 2 and 3). Hereinafter, the former is referred to as a usage state of the stove 2, and the latter is referred to as a storage state.

The switching unit 50 includes a first axis pair 51 provided on the frame body 10 and arranged so as to face each other, a second axis pair 52 provided on the frame body 10 and arranged so as to face each other, and each axis pair. A rotating member 57 rotatably provided with respect to each of the rotating shafts 55 forming 51 to 52, and a connecting mechanism 58 for connecting the fire bed 30 and the heat shielding plate 40 to each rotating member 57. Be prepared.

The two rotating shafts 55 forming the first axis pair 51 extend in the X direction, and are provided on the long side portions of the frame body 10 facing each other. The two rotating shafts 55 forming the second shaft pair 52 extend in the Y direction, and are provided on the short side portions of the frame body 10 facing each other. The rotating shafts 55 forming the first axis pair 51 preferably intersect with the rotating shafts 55 forming the second axis pair 52, and more preferably orthogonal to each other. The rotating shaft 55 is arranged along the inner peripheral surface of the frame body 10 in the internal space of the frame body 10.

The distance between the two rotating shafts 55 forming the first axis pair 51 is preferably longer than the length in the short side direction (Y direction) of the grill 20. The distance between the two rotating shafts 55 forming the second shaft pair 52 is preferably longer than the length in the long side direction (X direction) of the grill 20. It is preferable that the rotating shaft 55 is retracted to the internal space side of the front surface 10F (FIGS. 1 and 2) and the back surface 10B (FIG. 3) of the frame body 10. As a result, due to the rotating shaft 55 and the inner peripheral surface of the frame body 10, the accommodating portion of the grill 20 when the fire bed 30 or the like is in the internal position is on the front surface 10F (FIGS. 1 and 2) side and the back surface 10B ( It is formed on both sides of the FIG. 3) side.

As shown in FIGS. 1, 4 to 5, the rotating member 57 is formed in a plate shape. One end side of the rotating member 57 has a curved portion 57A having a radius of curvature substantially equal to the diameter of the rotating shaft 55. By engaging the curved portion 57A with the rotating shaft 55, the rotating member 57 becomes rotatable with respect to the rotating shaft 55. Further, the rotating member 57 is formed with two elongated holes 57R serving as rails. The elongated hole 57R extends in a direction orthogonal to the rotation shaft 55 to which the elongated hole 57R is attached. The elongated holes 57R are formed in parallel with each other. A wide hole 57Q, which is wider than the long hole 57R, is formed in the portion of the long hole 57R on the rotation shaft 55 side.

The elongated hole 57R may be provided so that the rotating member 57 can rotate. Therefore, the elongated hole 57R may extend away from the rotation shaft 55.

Slide pieces 31 are formed on both ends on the long side of the fire bed 30 and on both ends on the short side of the heat shield plate 40. The slide piece 31 includes a connecting portion 31T that connects to the fire bed 30, a slide portion 31S that extends from the connecting portion 31T and is slightly narrower than the width of the elongated hole 57R, and a wide portion 31B that is wider than the slide portion 31S. , Equipped with. The wide portion 31B can be inserted and removed from the wide hole 57Q. When the wide portion 31B is inserted into the wide hole 57Q, the slide portion 31S is narrower than the elongated hole 57R, so that the slide piece 31 can slide along the elongated hole 57R. Since the wide portion 31B is wider than the elongated hole 57R, it functions as a retainer. In order to prevent the slide piece 31 from falling out of the elongated hole 57R, it is preferable that the wide portion 31B is formed at a position close to the rotation shaft 55 in the elongated hole 57R. In this way, the elongated hole 57R and the slide piece 31 function as the connecting mechanism 58. Further, stoppers 40S for restricting the opening of the rotating member 57 connected to the fire bed 30 may be provided at both ends on the long side of the heat shield plate 40.

The frame body 10, the fire bed 30, the heat shield plate 40, and the switching unit 50 are made of highly durable materials such as stainless steel.

Next, how to use the stove 2 will be described.

In the stove 2 (FIG. 3) in the housed state, the fire bed 30 and the heat shield plate 40 are in the internal positions by the switching unit 50. The grill 20 is housed in the internal space behind the frame 10 in the housed state. At this time, since the fire bed 30 and the heat shield plate 40 are under the rotating member 57, the rotating member 57 does not rotate. Here, when the front and back of the stove 2 are reversed (FIG. 2), the fire bed 30 and the heat shield plate 40 are located on the rotating member 57, and the rotating member 57 becomes rotatable. Then, the slide piece 31 provided on the fire bed 30 or the heat shield plate 40 slides and moves along the elongated hole 57R of the rotating member 57. As a result, the switching unit 50 switches the fire bed 30 and the heat shield plate 40 from the internal position to the external position (FIGS. 1, 4, and 5). Depending on the orientation of the front and back of the frame body 10, switching and switching can be regulated by the switching unit 50, so that switching between the housed state and the used state becomes easy.

Although the stove 2 has been described in the above embodiment, the present invention is not limited to this, and the present invention can be applied to a housing that can be switched between a housed state and a used state, such as a lunch box and a packing material.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
