Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hinge device for a folding cover of a cargo ship.

BACKGROUND ART Conventionally, as a type of hatch cover device for opening and closing a hatch on a cargo ship, a folding cover is known in which the hatch cover is opened and closed using a wire from a shipboard winch or a crane. There is. That is, as an example of this, as shown in FIG. 4 of the attached drawings, several hatch covers 3 ₁ to 3 ₃ are arranged in parallel to each other over the hatch coaming 2 surrounding the periphery of the hatch of the hull 1. , adjacent ones are rotatably connected to each other by hinges 4 ₁ , 4 ₂ , and the cover 3 ₁ at one end is connected to the main hinge bracket 5 installed on the deck 1 ₀ of the hull 1 by a hinge pin 11 . Each cover 3 ₁ to 3 ₃ is attached so as to be pivotable through the hatch and the hatch is closed.
When opening the main hinge bracket 5, use a crane or the like to move the hatch cover ₃₁ close to the main hinge bracket ₅ and the hinge pin 11 to the main hinge bracket 5 via the wires 7 connected to the hatch covers 31 _to 33. The cover 3 ₂ that is vertically pivoted about the center and adjacent thereto is brought into an upright position in contact with the first hatch cover 3 ₁ about the hinge 4 ₁ that interconnects them, and so on.
A third hatch cover 3 ₂ adjacent thereto is attached to a second hatch cover 3 ₂ with the hinge arm 4 ₂ as the center.
and in this way each hatch cover ₃₁ to ₃₃ is retracted in a vertical position to open the hatch, and conversely to close an open hatch. Then, each of the hatch covers 3 ₁ to 3 ₃ is expanded over the hatch coaming 2 via the wire 7 by operating a crane or the like. In the case of blockage of the hatch covers ₃₁ to ₃₃ , a watertight device consisting of a gasket and a compression bar installed between each of the hatch covers ₃₁ to ₃₃ and the hatch combing 2 is operated. , Similarly, each hatch cover 3 ₁
~ _{3 The cleats fixed to 3} and the hatch coaming 2 are tightened manually or by operating a hydraulic cylinder, etc., so that the gasket is pressed by the tip of the compression bar and watertightness is achieved. . Of course, before opening the hatch covers 3 ₁ to 3 ₃ in the closed state, it is necessary to release the cleats. In addition, this hatch cover 3
The details of the main hinge bracket 5 for opening and closing of _the first hatch cover ₃₁ are as shown in _FIG . A hinge pin 11 is fixedly fixed in the vicinity of the lower end near the outer end of the hinge arm 10 provided in the hinge arm 10 in the vertical and horizontal direction, and the hinge pin 11 is fixed in the closed state of the hatch cover 3 ₁ . is an arc-shaped diagonal slot 1 formed in the hinge plate 12 that constitutes the main hinge bracket 5.
3 at the lowest end, and
Near the upper end of this hinge arm 10, a fixing pin 14 is attached almost vertically above the hinge pin 11 and parallel to the hinge pin 11, and the hatch cover 3 ₁ -
When the hatch cover 3 ₁ is opened, the hinge pin 11 fixed to the hinge arm ₁₀ attached to the hatch cover 3 1 touches the hinge plate 12 of the main hinge bracket 5.
A fixing pin 14 is guided through an arc-shaped diagonal slot 13 drilled in and reaches the upper end of the slot 13, and is fixed to the hinge arm ₁₀ . It is adapted to be supported at the section 15.

Problems to be solved by the invention As described above, in the conventional folding cover, each hatch cover 3 that makes up the folding cover
In order to change ₁ to 3 ₃ from open state to closed state,
After each hatch cover 3 ₁ to 3 ₃ is laid out horizontally on the hatch coaming 2, the watertight cleat is tightened by separate means, and the hatch covers 3 ₁ to 3 _{3 are}
It is necessary to maintain watertightness between the cleats and the hatch coaming 2, and in order to open the hatch covers ₃₁ to ₃₃ , which are in the closed state, first, the cleats must be closed by some means. There was an inconvenience that the hatch covers 3 ₁ to 3 ₃ had to be opened in a separate process after being released. This is mainly because the hinge pin 11 of the hinge arm ₁₀ of the first hatch cover 31 can freely move upward within the slot 13 formed in the hinge plate 12 of the main hinge bracket 5 even when the hinge pin 11 is in its closed state. This is based on the fact that it is possible.

Therefore, an object of the present invention is to provide a new hinge device for a folding cover of a ship that solves the problems of the conventionally known devices.

Means for Solving the Problems In order to achieve this object, the present invention provides a structure in which several hatch covers 3 ₁ to 3 3 are pivotally connected to each other, as shown in FIGS. 1 to ₃ of the accompanying drawings. , one end of the hatch cover 3 ₁ is connected to the main body mounted on the deck 1 0 of the hull 1 via a hinge arm 21 that is attached to the outer surface of the hatch cover 3 ₁ and protrudes in the longitudinal direction of the hatch cover 3 ₁ . In the folding cover for a ship, which is rotatably attached to the hinge bracket 5, the hatch cover 3 ₁ to
The hinge arm 2 of the hatch cover 3 ₁ adjacent to the main hinge bracket 5 when in the closed state of 3 ₃
A hinge pin 23 is attached to the hinge arm so as to be supported at the lower end of a substantially arc-shaped obliquely extending slot 24 bored in the hinge plate 22 of the main hinge bracket 5 near the outer end of the main hinge bracket 5 and near its lower part. A fixing pin 25 is fixed to the hinge arm 21 in the horizontal direction perpendicularly to the hinge arm 21, and a fixing pin 25 is fixed to the hinge arm 21 in the vicinity of its upper end. 23, another second fixing pin 27 is fixed vertically and horizontally to the hinge arm 21, while an upwardly extending portion of the hinge plate 22 constituting the main hinge bracket 5 is attached to the main hinge bracket 5. Above the slot 24, a second fixing pin 27 is inserted.
A slot 30 having an upper side for pressing from above is provided so as to open in the direction of the hinge arm 21 of the hatch cover ₃₁ , and the hinge plate 2
The upper edge 22 ₁ of 2 is provided with a bearing portion 26 for receiving the fixing pin 25 of the hinge arm 21 when the hatch cover 3 ₁ is opened vertically, and a second fixing pin 2 .
This folding cover hinge device is characterized by having a recess 28 for accommodating the folding cover 7.

Function When the hatch covers 3 ₁ to 3 ₃ are closed, the second fixing pin 27 fixed to the hinge arm 21 of the hatch cover 3 ₁ is pressed by the upper side of the slot 30 formed in the hinge plate 22 , so that the hatch cover 3 1 is closed. The watertight effects of the watertight devices ₁ to ₃₃ are not weakened by their repulsive action, and the watertight devices are automatically activated by the weight of these hatch covers ₃₁ to ₃₃ .

Embodiment Hereinafter, the present invention will be explained in detail based on FIGS. 1 to 3 showing one embodiment thereof.

First, as shown in Figure 1, the deck ₁ of the hull 1
For example, a main hinge bracket 5 of each hatch cover 3 ₁ to 3 ₃ is configured to open and close a pair of hatches arranged symmetrically with respect to the vertical center line of the hull 1. The vertical center line X-X ₍ the _third
A pair of horizontal hinge arms 21 are fixed at their bases in a direction parallel to this vertical center line XX, symmetrically with respect to FIG.
1 are each rotatably attached to a main hinge bracket 5 fixed on the deck ₁₀ of the hull 1. That is, each main hinge bracket 5
A pair of vertically parallel hinge plates 22 are fixedly spaced apart from each other (see FIG. 2), and a hinge arm 21 is loosely received between these hinge plates 22. A hinge pin 23 fixed vertically and horizontally near the lower end near the outer end of the hinge arm 21 is guided through an arc-shaped slot 24 formed upwardly at a slight angle in the hinge 22 plate. When the hatch cover ₃₁ is in the closed state, the hinge pin 23 is located at the bottom of the slot 24 of the hinge plate 22, as indicated by ₂₃₀ . Further, a fixing pin 25 is provided at the upper part near the outer end of the hinge arm 21, and is located almost perpendicularly above the hinge pin 23 when the hatch cover ₃₁ is in the closed state.

A gasket 31 is attached to the lower part of the inner surface of the vertical wall 20, and this gasket 31 is connected to a compression bar ₃₂ vertically fixed to the upper surface ₂₁ of the hatch coaming 2 when the hatch cover 31 is in the closed state. It is pressed by the upper end to maintain watertightness between the two.

Since the present invention has such a configuration,
As shown in FIG. 1, when the hatch cover ₃₁ etc. is in a closed state, its own weight causes the gasket 31 disposed on the inner surface of the side wall 20 to close to the compressor fixed perpendicularly to the upper surface ₂₁ of the hatch coaming 2. It will be pressed by the upper end of the tension bar 32, but in this case, the hatch cover ₃₁ is
Another second fixing pin 27 fixed near the outer end of the hinge arm 21 fixed to its vertical wall 20
is located at position ₂₇₀ and is prevented from moving upward by the upper side of the slot 30 formed in the upper extension of the hinge plate 22 of the main hinge bracket 5. It is possible to close the hatch cover ₃₁ and simultaneously achieve a watertight action by the gasket 31 and the compression bar 32 without having to tighten the cleat.

Effects of the invention As described above, according to the invention, the watertight action is automatically performed when the hatch cover is closed, and the watertight action is automatically released when the hatch cover is opened. The novel invention does not require a separate operation for securing or releasing watertightness between the hatch cover and the hatch combing before or after opening and closing, and is therefore easy to use. A hinge device for a folding cover is provided.
