Description

  TECHNICAL FIELD The present invention relates to an assembled cooking device suitable for use in outdoor leisure such as camping.

  2. Description of the Related Art Heating cookers such as barbecue stoves (grills) used in camps and the like are generally of an assembling type having a compact storage form that is easy to carry, for example, a type in which legs for supporting a main body are detachable, There are various types such as a type in which a main body can be folded and stored.

  As a type in which the main body can be folded and stored, there are, for example, those shown in Patent Documents 1 and 2.

  In any of Patent Documents 1 and 2, the peripheral portion of the main body portion is formed into a tubular shape (square tube) having a rectangular shape in a plan view by connecting a front plate, a rear plate, and two side plates to each other. The side plate is formed by connecting two plates of the same size to bend freely with a hinge, and by folding this side plate inward, the main body becomes a rectangular box (square tubular). It is configured so that it can be changed to a flat (flat) storage form from the use form.

JP 2016-17661 A Japanese Utility Model Publication No. 5-87401

  The type in which the conventional main body can be folded and stored has the above-described patent document because the shape of the main body is described above because the folding structure can be easily realized, and both the operations of assembling and folding and storing are easy. As shown in FIG. 1, a rectangular box is formed by a front plate, a back plate, and two side plates.

  In other words, in other words, when the main body is formed in a polygonal shape in plan view such that the main body has a substantially cylindrical shape, the number of plate-like members forming the main body increases, but this main body is formed. When the number of plate-like members increases, it becomes difficult to form the above-described folding structure, and it becomes difficult to realize another folding structure. In addition, many plate-like members are positioned and formed into a predetermined shape. Since it is not easy to (assemble) and maintain the shape, the shape of the conventional folding storage type main body is almost limited to a rectangular box shape as shown in Patent Document.

  However, when eating while cooking around the barbecue stove (grill), the shape of the barbecue stove (grill) is considered to be more convenient to use than a square shape (square), but conventionally, as described above. From such a viewpoint, as far as the applicant of the present application knows, there has not been proposed any type of barbecue stove (grill) having a cylindrical (substantially cylindrical) body in which the body can be folded and stored.

  Preferred embodiments of the present invention will be briefly described with reference to the drawings, showing the operation of the present invention.

  The main body 1 of the present invention is configured such that a plurality of metal plate-like members 4 are rotatably connected in the width direction via a rotation shaft 5 so that the shape when deployed is a horizontal rectangular shape. Therefore, when assembling at the time of use, each plate member 4 forming the main body 1 can be formed into a predetermined cylindrical shape by bending inwardly with respect to the adjacent plate member 4, respectively. Further, at the time of storage, it is possible to be wound into a spiral shape by performing a bending operation on the side opposite to the bending operation direction at the time of this assembling, and a compact storage form can be obtained.

  Specifically, according to the present invention, when each of the plate-like members 4 of the horizontal rectangular main body 1 in the unfolded state is bent inward with respect to the adjacent plate-like members 4, the plate-like members 4 At the time of bending to an angle, the bending becomes impossible due to the bending restricting portion 6, and a bending state of a predetermined angle with respect to the adjacent plate member 4.

  More specifically, according to the present invention, when the plate-shaped member 4 is bent inward with respect to the adjacent plate-shaped member 4, the bend restricting portion 6 approaches the adjacent plate-shaped member 4 and bends by a predetermined amount. The bending restricting portion 6 comes into contact with the plate-shaped member 4 and becomes incapable of bending by being abutted and locked by the adjacent plate-shaped member 4, and is bent at a predetermined angle with respect to the adjacent plate-shaped member 4. .

  That is, in the present invention, instead of bending the plate-like member 4 with respect to the adjacent plate-like member 4 while observing each angle, the plate-like member 4 is bent so as to be at a predetermined angle with respect to the adjacent plate-like member 4. By simply bending the plate-shaped member 4 inwardly until the plate-shaped member 4 cannot be bent with respect to the adjacent plate-shaped member 4, the plate-shaped member 4 is bent at a predetermined bending angle with respect to the adjacent plate-shaped member 4. Each plate-like member 4 is bent at a predetermined angle by the same bending operation, so that each plate-like member 4 is bent at a predetermined angle with respect to the adjacent plate-like member 4. When each of the plate-shaped members 4 is bent at a predetermined angle in the inward direction, the ends of the plate-shaped members 4 located at both ends at the time of development are connected to each other, and the main body 1 is formed in a substantially cylindrical shape.

  As described above, according to the present invention, the main body 1 can be easily formed into a substantially cylindrical shape to be used by a simple operation only by bending the main body 1 inward, so that the assembling is easy to use. It becomes a good assembling type cooking utensil.

  Further, according to the present invention, when the bending operation is performed to the outside in the direction opposite to the bending direction at the time of the assembling, since the bending restricting portion 6 does not function (does not interfere with the adjacent plate members 4), each plate member 4 is It is possible to freely bend and rotate in the outward direction without restricting the amount of bending, so that the main body 1 can be spirally wound into a compact form and not bulky during storage. Easy to carry.

  As described above, the present invention is an epoch-making assembling type cooking utensil which is excellent in practicality and has the substantially cylindrical main body 1 which can be folded and stored and is easy to assemble.
