Description

Door assembly for ladder and human body}

The present invention relates to a doorway, and more particularly to a marine doorway combining the human body and the ladder doorway.

In general, the entrance to the ship is formed on the side of the hull at a position higher than the ground bar, when the user boards the ship from the ground, or unloaded from the ship to the ground inevitably need an auxiliary mechanism such as a ladder.

Conventionally, the ship access ladder is protruded on the side of the hull and sailed with the ladder attached to the side of the hull, so the ladder is directly exposed to the harsh environment such as seawater and extreme temperature changes, and wear and damage There was a high risk of failure and frequent breakdowns due to corrosion.

In addition, since the ship entry ladder and the hull entrance and exit existed independently from each other, a lot of effort and time were consumed to fix the ladder at the exact position of the hull entrance when the user boarded or disembarked.

In particular, when used in naval ships, it is essential that naval ships operate without being detected by enemy radar observations.

However, the more the irregularities on the surface of the object, the better the characteristics of the radar are observed on the radar. Since the conventional naval vessels sailed with a ladder or the like attached to the side of the hull, many unnecessary irregularities were formed on the hull. Inevitably, there was a problem of being easily captured by the enemy radar network.

The present invention has been proposed in order to solve the above problems, the object of the ship is to be stored in a state that is not affected by the environment outside the hull by being accommodated inside the hull, ladders, etc. It aims to reduce the risk of breakage and corrosion of access ladders.

In addition, by combining the entrance to the ship and the human body entrance integrally, there is an advantage to reduce the time and effort by positioning the ladder in the correct place in a simple operation in a short time.

In particular, even when used in naval ships, by reducing the formation of irregularities by the ladder or the like on the surface of the navy ship, there is an advantage that can be minimized the possibility of being captured by the enemy radar network.

Human body and ladder door combination 100 according to an embodiment of the present invention having the configuration as described above is used as shown in Figures 7 to 11, as follows.

First, in order for a user to board a ship or board a plane from the ground, a process of opening the human body and the ladder entrance combination 100 according to the embodiment of the present invention will be described.

Initially, the human body and the ladder entrance assembly 100 according to the embodiment of the present invention, as shown in FIG. 7, is formed in the frame 10, the horizontal perforation part 12 and the vertical perforation part 11. ), The horizontal door member 30 and the entrance door member 20 are sealed, so as to be seen as one sealed plate when viewed from the outside.

In the above state, when the first hydraulic cylinder 24 is contracted, the end of the first protrusion 23 coupled with the first hydraulic cylinder 24 rotates about the vertical hinge axis 22. do. At this time, the link 26 coupled to the vertical hinge shaft 22 is also rotated around the vertical hinge shaft 22 in the direction of arrow A shown in FIG. 8.

In addition, since the vertical door 25 is connected to the end of the link 26, as the link 26 is rotated, the vertical door 25 is also rotated about the vertical hinge 21, Figure 8 It is rotated in the direction of the arrow A shown in FIG. 8 illustrates a state in which the vertical door 25 opens the vertical perforation part 11.

Subsequently, when the second hydraulic cylinder 34 is contracted, the end of the second protrusion 33 coupled with the second hydraulic cylinder 34 rotates about the rotation shaft 32. At this time, the arm member 36 coupled to the rotation shaft 32 is also rotated primarily in the direction of the arrow B shown in FIG. 9 with the rotation shaft 32 as the center.

In addition, since the horizontal door 35 is connected to the end of the arm member 36, as the arm member 36 is rotated, the horizontal door 35 is also rotated about the rotating shaft 32, Primary rotation is made in the arrow direction (B direction) shown in FIG. In FIG. 10, the horizontal door 35 opens the horizontal perforation part 12.

At this time, since the ladder member 40 is installed on the horizontal door member 30, the ladder member 40 also rotates when the horizontal door member 30 is first rotated about the rotation shaft 32. It rotates together around (32).

Subsequently, when the winch 37 installed on the side of the arm member 36 is rotated and the wire 38 is released, the horizontal door 35 coupled to the end of the wire 38 is moved downward. .

At this time, the horizontal door 35 is not directly coupled to the frame 10, the ladder 43 is provided on the surface of the horizontal door 35, the upper portion of the ladder 43 The upper scaffold 44 and the hinge is coupled, the upper scaffold 44 is coupled to the horizontal plate 41, the horizontal plate 41 is coupled to the rotating shaft (32).

Therefore, since the ladder 43 is hinged to one end of the upper scaffold 44, the ladder 43 rotates about the ladder hinge 46 when the wire 38 is released. In addition, the horizontal door 35 is also rotated twice around the ladder hinge 46, so that only the lower portion of the horizontal door 35 moves in the ground direction.

Here, the human body and the ladder entrance assembly 100 according to the embodiment of the present invention, the lower footrest 47 is hinged to the lower portion of the ladder 43 in the lower portion of the ladder 43 rotatably. The lower scaffold 47 contacts the ground.

In addition, the upper scaffold 44 and the horizontal plate 41 are coupled to each other by the through-hole 45 and the projection 42 to be rotatable, the ladder 43 to the projection 42 The lower scaffold 47 may be positioned at a desired place on the ground by rotating to the center.

Thus, the user is the ship through which the human body and the ladder entrance combination 100 is installed through the lower perforation 47, the ladder 43 and the upper scaffold 44 from the ground through the vertical perforation portion (11) or Board or get off the plane.

Next, after the user boarded or boarded the vessel from the ground, the process through the reverse process to the above-described process, the human body and the ladder entrance combination 100 according to an embodiment of the present invention is sealed.

As described above, according to the human body and the ladder entrance combination according to the present invention, the ship access ladder, etc. are accommodated inside the hull, so that it is stored in a state unaffected by the environment outside the ship body, and the damage of the ship access ladder, etc. And reducing the risk of corrosion.

In addition, by combining the entrance to the ship and the human body entrance integrally, there is an advantage to reduce the time and effort by positioning the ladder in the correct place in a simple operation in a short time.

In particular, even when used in naval ships, by reducing the formation of irregularities by the ladder, etc. on the hull surface of the naval ship, there is an advantage that can minimize the possibility of being captured by the enemy radar network.

Although the present invention has been described with reference to the embodiments illustrated in the accompanying drawings, it is intended to be illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom. .

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
