Claims

[Scope of utility model registration request]

(1) An outer mantle having a cylindrical structure or a pyramidal structure that can be formed by folding a single sheet-like material that can be folded flat along one folding plane; It is hinged to the inner wall of the mantle at two symmetrical positions with respect to the folding plane so that it can be folded flat together with the mantle, and the center axis of the mantle is fixed with the hinge-like fixing points as a fulcrum. at least one support plate portion that abuts against at least a portion of the inner side of the mantle to give the mantle a desired three-dimensional external shape when raised on a plane orthogonal to the mantle; and an assembled state; A structure for a foldable three-dimensional bulletin board, characterized in that it has at least one hook that engages with a slit provided in the mantle to support the support plate part in a raised state.

(2) ears protruding from two positions symmetrical with respect to the folding plane of the support plate portion of the support structure;
The structure according to claim 1, wherein the support structure is fixed to the inner wall of the outer mantle at the ears by aligning the folding planes of the support structure and the mantle. .

(3) The support plate portion has at least one axial extension extending along the folding plane in the direction of the central axis of the mantle, and the hook is attached to a pair of side edges of the axial extension. A pair of slits that are respectively provided to protrude outward on the folding plane from above and engage with the hooks are formed over a part of the length of the folding generatrix of the outer mantle. The structure described in Section 2.

(4) The above-mentioned support structure has two support plate parts, and the two support plate parts are connected by the above-mentioned axial extension part. , the structure described in any one of the items.

(5) The support plate portion has a pair of axially extending portions extending along the folding plane in both directions of the central axis of the outer mantle. The structure described in any one of the following.

(6) The flat plate part has one or more bendable protrusions on its peripheral edge, so that the inner wall of the mantle is supported by the bent surface of the protrusions in the assembled state. The structure according to any one of claims 1 to 5 of the patent registration claims.

(7) The structure according to any one of claims 1 to 6, wherein the support structure is formed by punching and bending a sheet-like material.
