Description

Rotatable Handrail {Rotatable hand-rail}

The present invention relates to a railing disposed on the top of a staircase used in ships and water structures, and more particularly, to a rotatable railing that can be closed by manual or automatic rotation of the entrance to the stairs.

The ship's dwelling area is where the cabins, steering rooms, control rooms, and other convenience facilities, where crews can reside, are located high on decks, like buildings. Outside the residence, there is a passageway for going up and down each floor.

The passageway is usually protruded outside the residence, and installed on each floor and installed inclined between the deck and a plurality of decks that can be carried by the crew, the stairway and the handrail installed on the outside of the deck to move the crew up and down It includes.

However, when pirates invade recently during the ship voyage, a dangerous situation that is difficult to guarantee the safety of the crew, in the passage passage structure of the vessel when the outsider such as pirates invaded the vessel, the cabin and a short time through the passage The ship can be infiltrated into the steering room, etc., and the ship can be easily taken over.

As a related art, Korean Patent Laid-Open Publication No. 10-2011-0019206 (published on Feb. 25, 2011), which is the prior art 1, has a stairway connecting the decks to each inside of the decks in an emergency situation by a predetermined rotatable means. The structure has been disclosed.

In addition, Korean Patent No. 1290693 (registered on July 23, 2013), which is Prior Art 2, discloses a configuration in which a ladder is selectively opened and closed using a hydraulic cylinder.

However, even when using the above-described prior art, since the entrance portion of each deck is exposed as it is, when using a separate rope or ladder, there is a problem that it is difficult to block the intrusion of outsiders such as pirates.

Korean Patent Publication No. 10-2011-0019206 (published Feb. 25, 2011) Korean Registered Patent No. 1290693 (registered July 23, 2013)

Embodiments of the present invention, by partially modifying the existing railing structure, by rotating it in the event of emergency provides a structure that can close the entrance to the stairs connected to the rotatable railing that can block the intrusion of outsiders such as pirates To provide.

In addition, after being closed manually or automatically, it provides a handrail that can be provided with additional fixing units to prevent outsiders such as pirates from easily overcoming the closed state.

According to an aspect of the present invention, the first railing disposed on one side of the doorway; A second railing disposed to face the first railing; And a third handrail disposed perpendicular to the first and second handrails, wherein the first and second handrails are rotatably configured to selectively close the doorway.

The first railing may include a first frame including a plurality of first gratings; And a first hinge portion rotatably supporting the first frame, wherein the first hinge portion may be fixed to the deck bottom surface.

The second handrail may rotate after the first handrail rotates to close the entrance and exit, and may rotate to move over the first handrail.

The first and second handrails may further include a fixing unit selectively engaged with the first handrail in a state in which the entrance is closed.

The fixing unit has a housing including a fixing pin which is installed to be retractable; And a fixing part having a pin hole coupled to the fixing pin at a position where the first railing closes the entrance. The fixing part may be formed on a first frame constituting the first railing.

A first drive unit rotating the first railing; And it may include a second drive unit for rotating the second handrail.

The first drive unit is connected to the first frame of the first handrail, the first cylinder for pushing or pulling the first frame; And a first support part fixed to the deck and supporting the first cylinder.

The rotatable railing according to the embodiments of the present invention may be configured to rotate the hinge to the portion connected to the deck while maximizing the existing railing structure, it is possible to obtain the maximum pirate exclusion effect at a minimum cost.

In addition, when using a separate cylinder device, the pressure of the cylinder can not solve the closed state of the railings by human force, and when the doors are closed by overlapping railings facing each other, the entrance can be closed more firmly. It has an effect.
