Description of the Related Art A lid of a cold-keeping box for fishing has one of its opposing sides pivotally attached to one of a plurality of non-detachable hinges or detachable hinges. The other was fixed to the box body by a pair of stoppers generally called a patch lock. With such a lid opening / closing structure, the lid can only be opened / closed from the side of the patch lock, so if the cold storage box is not in the correct orientation, change the orientation or move a human to operate it. Had to do. When opening and closing the lid, a pair of patch locks had to be operated. In addition, in the case of the detachable hinge, when the lid is separated from the box body, it is necessary to pull out the connecting shaft of the hinge in addition to opening the patch lock.
In addition, a general patch lock requires the lever to be rotated when opening and closing, and the lid cannot be opened because the lever cannot be rotated when there is no clearance with the trunk wall in the trunk of an automobile. was there. In addition, the lid can only be opened to one side, so when the orientation of the cool box in the trunk is not correct, the lid cannot be opened.

Is automatically swung around the lever shaft against the biasing force of the spring due to the slidable contact between the inclined portion on the lower surface of the tip of the engaging projection and the peripheral surface of the horizontal axis.
When the rib and the horizontal axis reach a certain relative position, all the horizontal axes except the lower end are surrounded by the inverted U-shaped bearing groove of the rib, and the lower end is locked by the engaging projection. The lid body is fixed to the box body via the horizontal axis. In this state, when one of the operating levers is swung around the lever shaft, the engagement between the lateral shaft on that side and the operating lever is released, and the lid swings around the other lateral shaft. It will be displaced. Further, when both operation levers are swung, the engagement between the horizontal shaft on each side and the operation lever is released, and the lid body can be separated from the box body.

体２から上方へ取り外されるものとなる。An example of use and operation of the above-described product of the present invention will be described. When closing the detached lid 1, the pair of L-shaped shafts 33, 33 on each side of the opposing surfaces of the box 2 are moved to the center of the operation window 42 by operating the spherical grip 35 first. Then, the pair of L-shaped shafts 33, 33 are positioned in the locking groove 43 by swinging the base ends of the pair of L-shaped shafts 33, 33 around their lateral axis, that is, around the hole h4. As a result, the pair of L-shaped shaft bodies 33, 33 are restricted to a fixed position in the lateral direction, and the respective tip portions 33a ... Are retracted from the concave bodies 41, 41. After that, the lid body 1 is placed on the box body 2, and the respective convex bodies 31, 31 thereof are fitted into the concave bodies 41, 41. The tongue-shaped piece 32 pushes down the base ends of the pair of L-shaped shaft bodies 33, 33 located in the locking groove 43, so that the convex bodies 31, 31 and the concave bodies 41, 41 are separated. When the required relative arrangement is achieved, those base ends are pushed out from the locking groove 43. For this reason, the pair of L-shaped shaft bodies 33, 33 are automatically allowed to move in the lateral direction at proper timing, and thereafter, their tip portions 33a are moved by the urging force of the compression coil springs 36. The convex bodies 31, 31 pass through the through holes h3 ...
41 is fitted into the hole h4 on the outer side wall. That is, the convex bodies 31 and 31 and the concave bodies 41 and 41 are connected via the L-shaped shaft bodies 33 and 33,
The lid body 1 is firmly fixed to the box body 2 in a closed state.
In this state, when the pair of L-shaped shaft bodies 33, 33 on one side of the facing surface of the box body 2 are moved to the lateral center of the operation window 42, the concave bodies 41, 41 on this side only .. are retracted to move the convex bodies 31, 3
Since the connection between 1 and the concave bodies 41, 41 is released, the lid body 1 is opened with the pair of L-shaped shaft bodies 33, 33 on the other side as the swing centers. That is, the lid body 1 can be opened from either side of the facing surface of the box body 2 with the pair of L-shaped shaft bodies 33, 33 on the other side as swing centers. Further, if the pair of L-shaped shaft bodies 33, 33 on each side are drawn toward the center of the operation window 42, all the convex bodies 31 ... And the concave bodies 41 ... Are uncoupled at once. Therefore, the lid body 1 is to be removed upward from the box body 2.
