以下、図示の実施形態に基づき本発明を詳説する。
本発明に係るゴミ保護ケースは、図１及び図２に示すように、全体が直方体形状であって、内部に収容空間を有し（中空であり）、下方開口状箱型の樹脂製のケース上半体１と、上方開口状箱型の樹脂製のケース下半体２と、を備えている。 Hereinafter, the present invention will be described in detail based on illustrated embodiments.
As shown in FIGS. 1 and 2, the dust protection case according to the present invention has a rectangular parallelepiped shape as a whole, has a housing space inside (is hollow), and is a box-shaped resin case having a downward opening shape. An upper half 1 and an upper opening box-shaped resin case lower half 2 are provided.

図２に示すように、ケース上半体１の後壁面の下端縁１ｂと、ケース下半体２の後壁面の上端縁２ａとは、ヒンジ部３によって、枢結され、ケース上半体１は、ケース下半体２に対して、左右水平状の枢結軸心廻りに開閉揺動自在である。 As shown in FIG. 2, the lower end edge 1 b of the rear wall surface of the case upper half 1 and the upper end edge 2 a of the rear wall surface of the case lower half 2 are pivotally connected by a hinge portion 3. Is openable and swayable with respect to the lower half 2 of the case around a horizontal pivot axis.

ヒンジ部３は、例えば、金属製の蝶番型のヒンジ部材30で構成され、一方の取付板がケース上半体１に固着され、他方の取付板がケース下半体２に固着されている。そして、一方の取付板と他方の取付板とを枢結する枢結軸廻りに、ねじりコイルバネから成るバネ部材35を巻き付け状に配設して、ケース上半体１を前方へ閉じる方向へ常時弾発付勢させている。 The hinge portion 3 is formed of, for example, a metal hinge-type hinge member 30, and one mounting plate is fixed to the case upper half 1 and the other mounting plate is fixed to the case lower half 2. Then, a spring member 35 made of a torsion coil spring is disposed around the pivot shaft that pivots the one mounting plate and the other mounting plate so that the case upper half 1 is always closed in the forward direction. The bullet is energized.

図３に示すように、ケース上半体１は、ケース下半体２に対して、左右水平状の枢結軸心廻りに、後方へ揺動して、開放自在である。この開放状態で、保護すべきゴミ（ゴミ袋）Ｇをケース下半体２の内部空間に収容可能となる。 As shown in FIG. 3, the case upper half 1 can be freely opened by swinging backward with respect to the case lower half 2 around the horizontal pivot axis. In this open state, the garbage (trash bag) G to be protected can be accommodated in the internal space of the case lower half 2.

開放状態から、ケース上半体１を前方へ閉じる方向へ揺動させる際に、ヒンジ部３に設けたバネ部材35の弾発付勢力が閉じる方向へ揺動させる閉操作補助力となって、軽い力で容易にケース上半体１を閉じることができる。
ケース上半体１の開口縁部とケース下半体２の開口縁部とが対面状に当接して配設され、閉揺動が終了する。
図４に示すように、ケース上半体１及びケース下半体２で包囲される内部空間にゴミ（ゴミ袋）Ｇを収容して保護する使用状態（ゴミ収容状態）となり、カラスやネコ等の鳥獣からゴミを保護する（ゴミが荒らされるのを防止する）。 When the case upper half 1 is swung forward from the open state, the spring biasing force of the spring member 35 provided on the hinge 3 becomes a closing operation assisting force that swings in the closing direction. The case upper half 1 can be easily closed with a light force.
The opening edge of the case upper half 1 and the opening edge of the case lower half 2 are disposed in contact with each other, and the closed swing is finished.
As shown in FIG. 4, the inside space surrounded by the case upper half 1 and the case lower half 2 accommodates and protects garbage (trash bag) G (trash containing state), such as crows and cats. Protect your trash from the birds and beasts (prevent trash from being devastated).

ゴミ収容状態（閉状態）で、鳥獣や強風でケース上半体１が後方へ押されても、バネ部材35の弾発付勢力が、開揺動を阻止する抵抗力となる。言い換えると、バネ部材35の弾発付勢力を、ケース上半体１を開揺動させようとする鳥獣や強風の力よりも大きく設定し、ケース上半体１を開揺動させようとする人（使用者）の力よりも小さく設定している。 Even if the case upper half 1 is pushed rearward by a bird or beast or strong wind in the dust storage state (closed state), the elastic urging force of the spring member 35 becomes a resistance force that prevents the open swing. In other words, the spring urging force of the spring member 35 is set to be larger than the force of the birds and beasts that try to swing the case upper half 1 or the strong wind, and tries to swing the case upper half 1 open. It is set smaller than the power of people (users).
