Description

WEATHER TIGHT DAMPER

BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to a weatherproof damper, and more particularly, to a weatherproof damper for effectively protecting an interior of a structure such as a ship from external environmental factors in maritime related operations.

In general, the ship is provided with a damper for providing fresh air to the space inside the ship and for protecting the inside of the ship from external environmental factors.

Specifically, the damper is opened to provide fresh air to the inside of the vessel, and is closed to protect the vessel from external environmental factors, such as the case where water penetrates into the vessel as the waves rise to the outside.

In order to achieve the above object, a conventional damper is provided such that a barb type blade rotates about a central axis.

However, the conventional damper has a problem in that it is difficult to perfectly protect the ship according to external environmental factors.

For example, in a conventional damper, when the wind velocity is large, the blades closed by the external wind pressure or the water pressure are rotated about the center axis, and a gap is generated between adjacent blades. That is, there is a gap between adjacent blades, and it is difficult for the damper to always stably protect the ship from external environmental factors.

In addition, conventionally, the entire blades are connected to each other by a link system so that they are collectively closed, and it is difficult to actively cope with external environmental factors. That is, the conventional damper has to open or close the entire blade at once regardless of the circumstances of the ship's external environment.

In addition, conventionally, even when rain or snow comes, the blades have to be closed to prevent water from penetrating into the vessel irrespective of the amount of precipitation.

That is, the conventional damper has a problem that it is difficult to operate efficiently.

Therefore, it is necessary to provide a damper capable of opening and closing the blades efficiently according to environmental factors outside the ship, and more stably protecting the ship from the external environment.

Registration Practical Utility Model No. 20-0466554 (April 16, 2013)

SUMMARY OF THE INVENTION It is an object of the present invention to provide a weatherproof damper in which a blade can stably protect a ship regardless of the environment outside the ship.

According to an aspect of the present invention, there is provided an image forming apparatus including: a casing unit having a hole formed on an inner side thereof and having a seating unit having a rim protruding forward; And a blade portion connected to the shaft portion inside the casing portion to rotate forward or backward, the blade portion having a main body forming a body and a bending member bent and extended from the main body edge, wherein the bending portion rotates backward Tight damper is coupled to the outer surface of the rim of the seat unit when the seat is made of a metal.

In one embodiment of the present invention, the casing portion includes a frame forming a body; And a boundary plate provided inside the frame and dividing the front and rear of the frame.

In one embodiment of the present invention, the shaft portion includes: a rod provided in the frame and extending to penetrate both side surfaces of the frame; And a rod housing provided at both ends of the frame, the rod housing being rotatably coupled to the rod housing.

In one embodiment of the present invention, a pivoting member has one end and the other end fixed to the rod and the main body, respectively. A first link member having one end fixed to the rod; And a link portion having a second link member hinged to the other end of the first link member, wherein the second link member is moved upward or downward in cooperation with the first link member .

In one embodiment of the present invention, the casing portion includes: a flange extending along the front and rear edges of the frame; A lifting lug having at least one of an upper surface and a lower surface of the frame and formed with through holes; And a limit bar provided inside the frame to determine the limit of the forward rotation of the blade portion.

According to an embodiment of the present invention, the apparatus may further include a driving unit that pivotally opens and closes the blade unit independently provided on both sides of the frame.

According to an embodiment of the present invention, when the blade portion is pivoted forward and opened, the blade portion may form an angle of 40 to 50 ° with the seating unit.

The effect of the weathertail damper according to the present invention described above will be described below.

According to the present invention, when the blade portion is pivoted rearwardly, the bending member and the seating unit are combined to safely protect the inside of the vessel from the external environment. In other words, in the state where the blade portion is closed, the displacement of the closed portion due to the external force is remarkably blocked by the firm coupling of the bending member and the seat unit, and the stronger the external wind, the more firmly the blade portion and the seat unit are tightly adhered, .

In addition, since the weathertight damper is provided with a pair of blade portions on the boundary plate and can be independently opened and closed, it is convenient to actively cope with the external environment of the ship.

Further, since the angle? Between the blade portion and the seat unit is 40 to 50 degrees, when the rain or snow falls, the blade portion serves as a roof of the seat unit. That is, even when the blade portion is in an open state, the vessel is protected so that a hole or an eye formed inside the seat unit is not introduced. The opened blade portion is inclined so that no snow or foreign matter accumulates on the main body. Therefore, when the rainfall amount or the snowfall amount is small, the weatherproof damper can protect the inside of the ship even in a state where the blade portion is opened.

It should be understood that the effects of the present invention are not limited to the above effects and include all effects that can be deduced from the detailed description of the present invention or the configuration of the invention described in the claims.

That is, the driving unit 500 may be configured such that when the user rotates the handle member 530, the driving unit 500 may be configured to rotate the blade unit 200 forward or backward by providing a driving force to the shaft unit 300, .

In addition, the driving unit 500 may further include a controller (not shown) for maintaining the state in which the blade unit 200 is rotated.

The driving unit 500 may be provided on both sides of the frame 105 so that the corresponding blade unit 200 can be independently opened and closed.

The driving unit 500 and the control unit can be easily implemented using conventional techniques, so that a detailed description thereof will be omitted.

Next, the closing process of the weatherproof damper 1000 will be described with reference to FIG.

First, when the handle member 530 connected to the driving unit 500 is rotated in one direction, the driving force is transmitted through the gear of the power transmitting unit 510, so that the rod 330 is rotated counterclockwise.

Next, the first link member 420 whose one end is fixed to the rod 330 is rotated counterclockwise along the rotation of the rod.

The second link member 430 hinged to the other end of the first link member 420 is moved upward by interlocking with the first link member 420 and the second link member 430 hinged to the second link member 430 The first link member 420 is simultaneously rotated counterclockwise along the second link member 430. [

As the rod 330 rotates counterclockwise simultaneously with the rotation of the first link member 420 and the second link member 430, the pivoting member 410 coupled to the rod 330 rotates backward do.

Next, as the tiltable member 410 is rotated backward, the blade unit 200 coupled with the tiltable member 410 is rotated backward. At this time, the main body 220 covers the front surface of the inner hole formed in the seating unit 140, and the bending member 240 is in close contact with the outer surface of the rim of the seating unit 140 and is closed.

Accordingly, when the blade portion 200 is pivoted rearward, the folding member 240 and the seat unit 140 can be combined to safely protect the inside of the ship from the external environment. In other words, in the state where the blade portion 200 is closed, the displacement of the closed portion due to the external force is remarkably blocked by the rigid coupling of the bending member 240 and the seating unit 140, 200 and the seat unit 140 are firmly in close contact with each other, thereby further improving airtightness.

Next, the opening process of the weatherproof damper 1000 will be described with reference to FIG.

First, when the handle member 530 connected to the driving unit 500 is rotated in the other direction, the driving force is transmitted through the gear of the power transmitting unit 510, so that the rod 330 is rotated clockwise.

Next, the first link member 420 whose one end is fixed to the rod 330 is rotated clockwise along the rotation of the rod.

The second link member 430 hinged to the other end of the first link member 420 is moved downward in interlock with the first link member 420 and the second link member 430 hinged to the second link member 430 The first link member 420 is simultaneously rotated counterclockwise along the second link member 430. [

Meanwhile, as the rod 330 rotates to the other side simultaneously with the movement of the first link member 420 and the second link member 430, the tiltable member 410 coupled to the rod 330 is rotated forward.

Next, as the tiltable member 410 is rotated forward, the blade unit 200 coupled with the tiltable member 410 is rotated forward. At this time, the weathertight damper 1000 is separated from the front surface of the inner hole formed in the seating unit 140, and the bending member 240 is also separated from the outer surface of the rim of the seating unit 140 and opened .

At this time, when the blade portion 200 is opened to the maximum, the bent portion of the pivoting member 410 is positioned at an angle α of 40 to 50 ° between the blade portion 200 and the seating unit 140, 150).

Since the angle between the blade unit 200 and the seat unit 140 is 40 to 50 degrees, when the rain or snow falls, the blade unit 200 serves as a roof of the seat unit 140. [ That is, even when the blade unit 200 is in the open state, the ship is protected so that a hole or an eye formed inside the seat unit 140 is not introduced. In addition, the opened blade portion 200 is inclined so that no snow or foreign matter is accumulated on the main body 220. Therefore, the weathertight damper 1000 can protect the interior of the ship even when the blade portion 200 is open, in case of a small amount of rainfall or snowfall.

Further, when the blade portion 200 is rotated forward, the hole formed in the inner side of the seat unit 140 is completely opened. Therefore, when the weathertight damper 1000 is in the open state, the area of the holes formed inside the seat unit 140 is increased, so that it is advantageous to ventilate the air inside the ship more quickly than the conventional damper in a short time.

The weathertight damper 1000 is provided with a pair of blade portions 200 and can be independently opened and closed, which is convenient because the weathertail damper 1000 can actively cope with the external environment of the ship.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
