Description

  The present invention relates to a cooking cooker suitable for use in outdoor leisure such as camping.

  Generally, cooking cookers such as barbecue stoves (grills) and the like used in camping and the like are in an easy-to-carry, compact storage form, for example, a type in which a leg supporting a main body is detachable or There are various types, such as types that can fold and store the main body.

  As a thing of the type which can fold and store this main-body part, there exist a thing as shown to patent document 1, 2, for example.

  In each of the Patent Documents 1 and 2, the peripheral surface portion of the main body portion is a tubular (square tube) having a square shape in a plan view, in which the front plate, the back plate and the two side plates are respectively pivotally connected. The side plate is formed by connecting two plates of the same size in a bendable manner with a hinge, and by folding the side plate inward, the main body portion is shaped like a rectangular box (square cylinder) It is comprised so that it can be made into the flat form (flat form) storage form from a use form.

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

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

  That is, in other words, when the main body portion is formed in a polygonal shape in plan view so as to exhibit a substantially cylindrical shape, the number of plate-like members forming the main body portion increases, but the main body portion is formed When the number of plate-like members increases, it becomes difficult to provide the above-described folded structure, and it becomes difficult to realize another folded structure, and many plate-like members are positioned and formed into a predetermined shape.

  The preferred embodiments of the present invention will be briefly described by showing the operation of the present invention based on the drawings.

  The main body portion 1 of the present invention is configured such that a plurality of metal plate members 4 are pivotally connected in the lateral width direction via the pivot shaft 5, and the shape at the time of deployment exhibits a horizontal rectangular shape Therefore, when assembling at the time of use, it can be formed into a predetermined cylindrical shape by bending the plate-like members 4 forming the main body 1 inward with respect to the adjacent plate-like members 4, Further, when stored, it can be wound into a spiral shape by bending operation in the opposite direction to the bending operation direction at the time of assembly, and a compact storage configuration can be achieved.

  Specifically, according to the present invention, when each plate-like member 4 of the horizontally rectangular main body 1 in the unfolded state is bent inward with respect to the adjacent plate-like member 4, the plate-like member 4 is bent in a predetermined manner. When it bends to an angle, it becomes inflexible by the bending control part 6, and it will be in the bending state of a predetermined angle with respect to the adjacent plate-like member 4. FIG.

  More specifically, according to the present invention, when the plate-like member 4 is bent inward with respect to the adjacent plate-like member 4, the bending restricting portion 6 approaches the adjacent plate-like member 4 and is adjacent when bent by a predetermined amount. When it abuts on the plate-like member 4 and the bending restricting portion 6 abuts on and abuts on the adjacent plate-like member 4, it becomes inflexible and bends at a predetermined angle with respect to the adjacent plate-like member 4. .

  That is, according to the present invention, the bending operation of the plate-like member 4 is not performed so as to be a predetermined angle with respect to the adjacent plate-like member 4 while the bending operation is performed while looking at the angle one by one The bending angle of the plate-like member 4 with respect to the adjacent plate-like member 4 is simply determined by simply bending the plate-like member 4 inward until the bending operation becomes impossible with respect to the adjacent plate-like member 4. And 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. By bending the shape members 4 inward at a predetermined angle, the end portions of the plate members 4 positioned at both ends at the time of deployment are connected to form the main body portion 1 in a substantially cylindrical shape.

  As described above, according to the present invention, since the main body portion 1 can be easily formed into a substantially cylindrical shape to be used by a simple operation of bending the main body portion 1 inward, it is easy to assemble and use It becomes a good assembly type cooking device.

  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 assembly, the bending restriction portion 6 does not function (does not interfere with the adjacent plate-like member 4). The outside direction can be freely bent and rotated without restriction of the amount of bending, whereby the main body portion 1 can be wound in a spiral shape to be in a compact form and not bulky at the time of storage Easy to carry.

  As described above, the present invention is a highly practical and revolutionary cooking cooker having a substantially cylindrical main body 1 which can be folded and stored and which is easy to assemble.

  Moreover, the mounting part 3 for foodstuffs adjusts the set position by the purpose of use. For example, when used as a barbecue grill, the hooked portion 9A of the uppermost step of the support portion 9 is fitted and attached, and when used as an oven, near the middle step of the support portion 9 The hooked portion 9A is attached to the hooked portion 9A by fitting the engaged portion 3A.

  Thus, the assembly of this embodiment is completed. The above assembly procedure is only an example, and the attachment order of the leg 2, the food placing portion 3, and the heat source placing portion 10 can be changed, and the leg in advance in the unfolded state of the main body 1 2 may be attached, and the main body 1 may be assembled in a state in which the legs 2 are attached.

  As described above, according to the present embodiment, since the main body portion 1 can be easily formed into a substantially cylindrical shape to be used by a simple operation of bending the main body portion 1 in the inward direction, assembly is easy. It becomes a user-friendly assembly-type cooking device.

  Further, in the present embodiment, when the bending operation is performed to the outside in the direction opposite to the bending direction at the time of assembly, the bending restriction portion 6 does not function (does not interfere with the adjacent plate-like member 4). Can be freely bent and rotated in the outer direction without restriction of the amount of bending, whereby the main body portion 1 can be wound in a spiral and can be made into a compact form. It becomes easy to carry.

  As described above, the present embodiment is an innovative assembly type cooking device excellent in practicability including the body portion 1 formed in a substantially cylindrical shape that can be folded and stored and is easy to assemble.

  The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
