Abstract

(57) [Summary] [Purpose] To provide a door that can be used as a recess door and a davit for ships, etc., which requires almost no installation space. [Structure] In a ship or marine structure in which boats such as survival boats, rescue boats, tender boats, etc. are stored in a recessed part of the main hull, a door 10 that can be opened and closed in the recessed part of the main hull that forms a storage place for the boat 3 is used. Closed and the door 10 is used as part of the boat davit of the storage boat.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a door that doubles as a boat davit for ships and offshore structures.

0002

[Conventional technology]

Boat propulsion for survival boats, lifeboats, rescue boats, tender boats (excursion boats, landing craft), etc. The water system or boat davit is independent of the main hull or hull skin. Of course, doors attached to the main hull skin are also separate from the main hull. .

0003

[Problem that the idea aims to solve]

As shown in Figures 10 to 14, there are several types of boat davits of this type. Various structures are known, but in all of them, the boat davit 2 is in the boat storage state. Due to the need for a large space on deck 12, such as the boarding deck, on actual ships, It is important to ensure a wide and safe space for boarding, gathering, and walking. It's not easy. In addition, as shown in FIGS. 1 to 3, a recess 1a is provided in the main hull 1, and a button is provided here. When storing boats, use the storage space for boat 3 and boat davit 2. A larger recess must be provided, reducing the amount of guest space that must be reserved in the enclosed area. I have no choice but to.

0004 This invention was proposed in view of these circumstances, and was developed for boat davit 2. Boat navigation for ships and offshore structures that require little storage or installation space. The purpose of this project is to provide a door that can be used as a multi-purpose door.

[0005]

[Means to solve the problem]

For this purpose, the present invention is designed for boats such as survival boats, lifeboats, rescue boats, and tender boats. In ships, offshore structures, etc., where the above-mentioned boats are stored in recesses in the main hull. The main hull recess forming the location is closed with a door that can be opened and closed, and the door is retracted above. It is characterized by being used as a part of the boat davit 2 of a boat.

[0006]

[Effect]

As shown in Figures 1, 3, 4, 6, 7 and 9, the boat launching device or The boat davit double door 11 forms a part of the main hull outer plate 1, so the boat davit double door 11 forms a part of the main hull outer plate 1. The bit installation space (required deck area) can be omitted. Furthermore, the boat davit door 11 is swing-out type, making it easy to get on the boat. Not only can it be used as an entrance/exit door to the boat deck 12, but it is also wide enough for getting on and off the boat 5. You can secure a meeting place. In addition, by adopting the telescopic arm 6 for boat davits, the other fixed arm 2 can be shortened. This allows the boat 3 to be stored more compactly. of course , when the boat is launched with the boat davit door 11 swung out to the side of the boat, the boat is the main vessel. It can be made parallel to the outer body plate 1, and can be launched safely without hitting the main hull.

To explain the present invention in terms of an embodiment, FIG. 1 shows the scale of a boat showing the first embodiment. Figure 2 is a plan view of the boat shown in Figure 1 when launched, Figure 3 is a plan view of the boat shown in Figure 1 when it is launched. Figure 4 is a cross-sectional view of the boat when it is delivered and launched, showing the second embodiment of the present invention. 5 is a plan view of the boat in FIG. 4 when it is launched, and FIG. 6 is a plan view of the boat in FIG. 4 when it is stored and 7 is a cross-sectional view when the boat is launched, and FIG. 7 is a plan view when the boat is stored, showing the third embodiment of the present invention. 8 is a plan view of the boat in Figure 7 when it is launched, and Figure 9 is a plan view of the boat in Figure 7 when it is stored and launched. FIG. In the above diagram, 1 is the main hull outer plate, 2 is the boat davit, and the boat 3 is launched. Acts as a fixed arm of the device. 6 is a telescopic arm for boat davits, Hold the loaded boat 3 in a position parallel to the ship's side, and open the boat davit door 1. It is hinged to 1. 7 is an arm extension device, and the arm is shown in Figures 1 to 6. 6 is shown, and in Figures 7 to 9, the hydraulic cylinder for arm 6 is shown. show. 8 is a pulley, 9 is a wire, and the wire connects the telescopic arm 6 and the arm telescoping device 7 (window). h). 10 is a fire safety door, located at the tip of the boat davit door 11. Consists of fire-resistant plates attached with hinges to prevent fire from spreading outside the ship in the event of a fire inside the ship. . 11 is a door that doubles as a boat davit, and is attached to the boat davit column 13. It is made of a fireproof board and frame, and a boat davit 2 is installed at the tip, allowing you to board the boat. To protect passengers who have boarded or are about to board from fire on the ship's side. 12 on the deck Depending on the purpose of use, it is used as a boarding deck or a walking deck for the boat 3. 13 is bo It is a support for a door that doubles as a davit, and is rotatably installed on the main hull outer panel 1 and on the deck 12. It is. First, FIGS. 1 to 3 each show a first embodiment of the present invention, and each shows a boat navigation system. The boat door 11 and the boat position holding devices 6 to 9 at the time of launching are shown. Next, FIGS. 4 to 6 each show a second embodiment of the present invention, and respectively show the first embodiment of the invention. As an example, a fire prevention safety door 10 is attached to a boat davit door 11 when the boat is launched. Indicates what has been added. Here, 15 has the same function as the boat davit door 11. A door that doubles as a ladder for boarding and disembarking a boat, the recess is windproof, waveproof, and rainproof, making it easy to board and disembark the boat. It also becomes a time ladder. Furthermore, FIGS. 7 to 9 each show a third embodiment of the present invention, and each is similar to the first embodiment described above. The example shows a fire prevention safety door 10 added to the main hull outer plate 1 when the boat is launched. vinegar.

[0008]

[Effect of the idea]

The structures shown in FIGS. 1 to 9 each include a part of the main hull skin 1 as a launching device for a boat 3, In other words, by using the boat davit 2 and the door 11, the mounting part of the boat davit Therefore, the required deck area can be omitted. In addition, the swinging part of the boat davit, that is, the door 11 that also serves as a boat davit, is By adopting this, a large deck area can be secured for boarding and disembarking from Boat 3 and as a gathering place. Furthermore, by adopting the telescopic arm 6 for boat davits, the other fixed arm 2 can be shortened. By making the boat 3 smaller, the boat 3 can be stored more compactly. And then When the boat 3 is swung out, that is, when it is launched, the boat 3 and the main hull shell 1 are kept parallel. It can be safely launched into the water without hitting the hull.

[0009] In short, according to the present invention, boats such as survival boats, lifeboats, rescue boats, tender boats, etc. In ships, offshore structures, etc. where the boat is stored in a recess in the main hull, The recessed part of the main hull that forms the storage space is constructed with a door that can be opened and closed, and the above door is isolated. By using it as part of the boat davit 2 of the storage boat mentioned above, the boat davit For ships, offshore structures, etc. that require little storage or installation space for Bit 2. This invention is extremely useful industrially because it allows a door to be used as a boat davit. It is.
