および点検に支障をきたす等の欠点がある。This type of conventional box lid device uses a hinge to open and close the lid attached to the receiving frame, but in order to be able to open the lid more than 90', the hinge must not protrude from the top of the lid. Since it needs to be installed at a high position, there are drawbacks such as a large load acting on the hinge when opening and closing the lid, which not only causes severe damage to the hinge, but also makes it difficult to open and close the lid, making cleaning and inspection difficult. be.

本考案は前記のような欠点のない桝蓋装置を目的として
完成されたもので、以下、図示の実施例について詳細に
説明する。The present invention was completed with the aim of providing a box cover device that does not have the above-mentioned drawbacks, and the illustrated embodiment will be described in detail below.

せて揺動自在に取付けられている。Reference numeral 1 denotes a lid of a drainage basin lid, and a receiving frame 2 that is opened and closed with the lid 1 is made of angle-shaped steel members 2', 2' with the lower side member 2'' inside, and plates 2///, 2ttt. The frame is connected as a frame on both sides, and guide pins 3, 3 are located above the lower side member 2'' on the opposing side surfaces of one end of each of the opposing plates 2'', and are provided with guide pins 3, 3 facing inward at a constant interval. On the other hand, as shown in FIGS. 2 and 3, a pin 4 is fixed to the lid 1, the tip of which is interposed between the guide pins 3 and 3 when the lid 1 is closed. At the front end of the pin 4, there is a slider 5 whose lower end is a protrusion 6 for preventing removal which is larger than the gap between the guide pins 3 and 3. A slight gap is provided between it and the upper surface, and the upper end is positioned between the guide pins 3, 3, so that it can swing freely.

ない抜は止めの状態となって静置される。With this structure, when the lid 1 is opened from the closed state shown in FIG. The slider 5 rotates around its lower end as a fulcrum, and then one side of the slider 5 comes into contact with one of the guide pins 3, which are arranged in parallel at a constant interval, and from then on, the slider 5 rotates around its lower end. As it rotates, the slider 5 is guided by the guide pin 3 so that the guide pin 3 is used as a fulcrum, and the lower end of the lid 1 slides on the lower side member 2'' of the receiving frame 2. Further, when the opening angle of the lid 1 becomes large and the lower end part is separated from the upper surface of the lower side member 2'' as shown in FIG. The lower surface of the protrusion 6 is brought into contact with the lower side member 2'', and the lid body 1 is attached to the lower side member 2'' via the slider 5.
After that, the lid 1 is rotated around the pin 4, and when the opening angle exceeds 90° and the upper surface of the lid 1 touches the upper end of the receiving frame 2, as shown in FIG. As shown in , the lid body 1 is rotated about the upper end portion as a fulcrum, and the end portion thereof rises, and the floater 5 also floats above the lower side member 2″. The body 1 slides diagonally downward on the upper end of the support frame 2 due to its own weight, but the sliding is prevented when the other side of the floater 5 comes into contact with the opposing guide pin 3. Even if the lid 1 slides down due to the opening movement, as shown in FIG. The slipping is completely prevented, and when the lid 1 is opened 180 degrees as shown in FIG. It is left still in a state where it does not pass through the gap.

このように蓋体１は１８０°以内の適宜の角度に開閉さ

は遊動子５を介して下辺部材２″上に支持されてピン４
を中心とする回動となり、さらに、開き角度が大となる
と受枠２の上端部により支持されて回動されるため、蓋
体１は常に僅かな労力で容易に開閉できてピン４に無理
な荷重が加わらないため長期間の使用に耐えることがで
きる。In this way, the lid 1 is opened and closed at an appropriate angle within 180°, but while the opening angle of the lid 1 is close to 90°, the lower end of the lid 1 slides on the lower side member 2'' of the receiving frame 2. The lid body 1 moves and its weight is supported, and when the opening angle is around 90°, the lid body 1
is supported on the lower side member 2'' via the floater 5, and the pin 4
Furthermore, when the opening angle becomes large, the lid 1 is supported by the upper end of the receiving frame 2 and rotated, so the lid 1 can be opened and closed easily with little effort and does not force the pin 4. Since no load is applied, it can withstand long-term use.

なお、本実施例では受枠２は山形鋼材２′と板材２″と
より構成されているが、山形鋼材のみより構成させても
差支えなく、また、溝蓋装置としても使用できることは
勿論である。In this embodiment, the receiving frame 2 is made up of an angle steel material 2' and a plate material 2'', but it can also be made of only an angle steel material, and of course it can also be used as a gutter cover device.

本考案は前記実施例による説明によっても明らかなよう
に、僅かな労力で蓋体を容易に開閉できるうえに回動部
分の寿命の長いもので、掃除および点検などを行ううえ
