Description

[Detailed Description of the Invention] This invention relates to an improvement of a sliding door provided in the outer panel of a ship.

Regarding the modified door, for example, the one shown in Japanese Patent Publication No. 45-8931 is known, but in this known technology, a part of the door is removed from the outer panel during the initial opening movement of the door. It has a configuration in which a device for pushing outwards is attached to the bottom of the door, and has drawbacks such as a complicated structure and a lack of smoothness in the opening operation of the top of the door.

Therefore, an extrusion device is installed above the opening of the outer plate,
When the door is opened, the upper part of the door is first pushed outward by the pushing device, and then the door is guided by a lower guide rail having a diagonal guide section at the lower part, and the door is moved upward and outward. Door (patent application 1976-682)
9) was proposed.

However, in this case, there is a feeling of instability during operation because the door is tilted once when the door is opened, and there is a risk of excessive force being applied to a part of the gasket.In addition, since the lower guide rail is provided with a sloped part, It had drawbacks such as being difficult to work with.

In this invention, a pushing device is provided at both the upper and lower parts of the opening of the outer panel, and when the door is opened, the pushing device first pushes the door outward in parallel with the outer panel, and then the door is pushed out in a straight line with a horizontal guide portion. By moving the door outward and upward while being guided by the upper and lower guide rails of the structure,
The object of the present invention is to improve the above-mentioned drawbacks and provide a sliding door that has a simple structure and is easy to manufacture.

Next, an embodiment of this invention will be described with reference to the drawings. A is a door, B is an outer panel of a ship, and the door A enters and exits through the opening 1 of the outer panel B.

A series of gaskets 2 are provided on the inner outer periphery of the door A by a gasket shrouding plate 3, and a gasket presser 4 is provided in a series on the peripheral edge of the opening 1 facing the gaskets 2.
In addition, in parallel with this, a tightening tool 5 operated by a hydraulic device etc.
is provided.

Brackets 6 projecting inward are provided on both sides of the lower part of the door A, and a roller 1 provided at the tip of the bracket 6 engages with a lower guide rail 8.

The lower guide rail 8 consists of a lower horizontal guide part 8a necessary for the door A to be pushed out completely outside the outer plate B, and a vertical guide part 8b continuous thereto.

Rollers 9 are provided at both upper ends of the door A and engage with an upper guide rail 10.

The upper guide rail 10 consists of a lower horizontal guide part 10a necessary for the door A to be completely extended to the outside by the outer plate B, and a vertical guide part 10b continuous with the lower horizontal guide part 10a.

Hydraulic cylinders 11 and 11' as extrusion devices are provided on the hull side at the center of the upper and lower parts of the opening 1, and their piston rods 12 and 12' move in and out toward the outer plate B.

Engagement portions 13 are provided at the tips of the piston rods 12 and 12', respectively.
．． 13' is provided, and the engaging portion 13.13' is provided with a door A.
A two-pronged engagement piece 1 with a lower end opening provided at the upper and lower parts of the
4 and 14' are engaged.

Next, to explain how to use it, in order to open the door A from the closed state shown in FIG. 12, 12' connect door A to outer plate B
Push outward.

At this time, the door A is pushed outside due to the relationship between the upper and lower rollers 9, 1 and the horizontal guide portions I Da and 8a of the upper and lower guide rails 10 and 8, and this causes the sealing shroud plate 3 and the packing presser foot 4 to engage with each other. The upper and lower rollers 9, 7 come off and reach the vertical guide portions IQb, 8b.

In this dog position, the door A is raised via the wire 15 connected to the bracket 16 by the drive of a winch or the like, and the door A is guided by the upper and lower guide rails 10°8 and positioned completely outside the outer panel B. At the same time, it is located above the opening 1 (FIG. 5) and is fixed by a known locking device (not shown).

For the closing operation, the door A is lowered along the guide rails 8, 10 by loosening the wire 15, and when it reaches the lowest position, the two-pronged engagement pieces 14, 14' engage the piston rods 12, 12'. The hydraulic cylinders 11, 11 are engaged with the joints 13, 13' and return to the state shown in FIG.
' to pull the piston rod 12°12' into the third position.
Close as shown.

As explained above, in this invention, extrusion devices are provided on both the upper and lower parts of the outer panel that accommodates the door, and upper and lower guide rolls are provided that have horizontal guide portions that engage with the rolls provided on the upper and lower sides of the door. Since the sliding door moves outward and upward in a straight line, the opening/closing operation of the door is smooth and stable, and the sliding door is simple in structure and easy to manufacture.
