Description

Hand rail device and ship having same {Hand rail device and ship having same}

The present invention relates to a hand rail device and a ship having the same.

Generally, handrails are installed in the passageways where workers move in large structures such as ships to prevent falls, and in areas where handrails are installed, part of the handrails is removed in areas where workers need to leave the passageways and move to stairs, ladders, etc. It also forms an entrance.

As shown in FIG. 1, an entrance bar 3 (hereinafter referred to as a drop bar) may be hinged to one side of the handrail 1 to open and close the entrance 2 formed on the handrail 1.

For example, when the drop bar (3) is fixed to the handrail (1) in a horizontal direction, it can close the entrance (2) and function as part of the handrail (1), and when rotated upward, it can close the entrance (2) can be opened.

However, since the above-mentioned drop bar 3 must secure a rotation space corresponding to the rotation radius of the entrance 2, the installation location is limited, and collisions with other structures or pedestrians may occur during the rotation of the entrance.

In addition, since the drop bar 3 requires a hinge structure and a stop device that can fix the entrance in a rotated state, there is a problem in that the overall structure of the entrance becomes complicated.

In particular, when using a vertical ladder, workers have to move while holding the handrail with one hand and lifting the drop bar with the other hand. If the drop bar is long, the hand must be moved to a position that is sufficiently open for passage. In some cases, it may not reach, so a collision with the drop bar may occur when moving to the top of the deck.

This can not only cause discomfort to the worker, but also cause safety accidents such as falls and slips due to loss of balance due to one hand not being free.

One object of the present invention is to provide a hand rail device that facilitates opening and closing of an entrance and a ship having the same.

One object of the present invention is to provide a hand rail device that can minimize the space required for the opening and closing operation of an access bar that opens and closes an entrance, and a ship having the same.

One object of the present invention is to provide a hand rail device that can be opened to a width required for passage by an operator, and a ship having the same.

The problem to be solved by the present invention is not limited here, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

According to one aspect of the present invention, a handrail member having a first handrail, a second handrail, and an entrance formed between them; Includes an entrance bar that opens and closes the entrance and exit; The entrance bar may be provided with a hand rail device having a structure in which unit blocks are hingedly connected to each other and folded.

Additionally, the entry/exit bar may be provided to maintain a horizontal state when unfolded.

Additionally, the entry/exit bar can be folded only in the upward direction.

Additionally, the first unit block located at one end of the access bar may be fixed to the first handrail, and the second unit block located at the other end may be seated on the second handrail.

Additionally, the second railing may include a hold on which the second unit block is seated.

Additionally, the entry/exit bar may include a pin that connects the unit blocks to each other in a hinged manner, and a hinge pipe formed integrally with the unit block so that the pin is inserted.

Additionally, the access bar may be installed opposite to each other on the first handrail and the second handrail.

According to an embodiment of the present invention, the foldable entrance bar folds the handrail inside the entrance (passageway) as needed for work to avoid inconvenience in passing, and after work is completed, it can be unfolded to prevent workers from falling accidents. .

According to an embodiment of the present invention, the foldable entry/exit bar can be easily folded or unfolded by an operator.

According to an embodiment of the present invention, the space required for the opening and closing operation of the access bar for opening and closing the entrance can be minimized.

According to an embodiment of the present invention, the worker can open the door to the width required for passage.

The effects of the present invention are not limited to the effects described above, and effects not mentioned can be clearly understood by those skilled in the art from this specification and the attached drawings.
