In FIG. 5, reference numeral 101 is a hull deck, 102 is a doubler, and 103 is a anchor chain. 104a is a side plate, 104b is a closing stopper guide, 104c is a bearing, 104d is a hole for an opening stopper, 104e is a latch for an opening stopper, 104f is a reinforcement, 104g Is a hinge member, 104h is an actuating lever, 105 is a cleat, 106 is a closing stopper, 106a is an actuating shaft, 107 is a connecting metal, 107a and 107b are pins, 108 is a rolling shaft, 108a and 108b are rolling levers, 109 Is a mount, 111a is a cylinder head hardware, 111b is an operating projection, 111d is a pin, 112 is an operating shaft, 112b is a pin, 4 the open Sutotsupa actuating shaft, 114c are projections, 115 eye plates, 119 is link mechanism.

  In addition, in Japanese Utility Model Publication No. 5-11114, as an example of the hinged chain lid cover 101 ″ of the chain chain lid apparatus when the chain hole diameter is large, a plan view of the apparatus (FIG. 6 (a)), the same side surface is shown. FIG. 6 (b) is disclosed (see FIG. 10, FIG. 2, b), and this hinged anchor hole lid 101 ″ is pivotally attached to the hull by a hinge 106 ″ on the hull. The same chain hole lid 101 "can be rotated up and down around the hinge 106", and the opening and closing operation of the hinged chain hole lid 101 "is performed on the handle 104 provided on the upper surface of the same chain hole lid 101". ”, And the chain hole cover 101′101” is fixed to the hull with a hardware such as a pin (not shown) in the closed state. (See the same publication, page 1, column 2, lines 8 to 19) Incidentally, in FIG. 6 (a) (b), reference numeral 101 "is hinged anchor chain Anafuta, 104" includes a handle, 106 'are hinged, 105 "is engageable portion.

Conventional anchor chain hose pipe covers such as those disclosed in Japanese Utility Model Publication No. 5-11114 are typically two-part hinged ones as shown in FIG. The one that opens in the length direction is adopted.
FIG. 7 is a diagram schematically showing a conventional anchor chain hose pipe cover. In FIG. 7, reference numeral 201 denotes an anchor chain hose pipe cover, 202 denotes an anchor chain hose pipe upper opening, and 203 and 203 denote Hinges 204a, 204b, and 204c are toggle pin stoppers, and 205 and 205 are stopper bolts.

  As shown in FIG. 7, this anchor chain hose pipe cover 201 is a one-side hinge type, so that the anchor chain (not shown) and the cover 201 are prevented from contacting the anchor chain (not shown) when opening and closing. It has a shape with a gap between them. Therefore, when the cover 201 is closed, the margin becomes a large gap, and there is a problem that it is used as a means for illegal intrusion of a thief or the like climbing an anchor chain from the outside of the ship.

Further, the bolts 205 and 205 for preventing the opening have a problem that, as time passes, the threaded portion becomes difficult to screw due to rust or dust clogging. Further, since the cover 201 is made of a round bar, there is a problem that the hand can be easily put in, the stopper is released, and a thief or the like can illegally enter.
