Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
a new ladder system with a war ladder equipped with an arf ladder).

[0002]

2. Description of the Related Art A lower platform is provided at the lower end of a ship ladder. This lower platform is maintained in a horizontal position when the berth is used, improving the ease of getting on and off the berth. The deck is stored when it is not in use, that is, when the vessel is navigating, but in order to make the storage space small and secure a wide passage etc., the lower platform is usually rotatable around the horizontal axis so that the deck main body can be adjusted. It is attached to, and the posture can be changed so as to follow the main body of the ladder.

[0003] In such a conventional berth, when a ship is moored to the quay, the berth is lowered, and a wad ladder device (commonly called "gang board") separate from the berth is attached to the lower platform and quay of the berth. It is laid between the two to make it easier and more convenient to get on and off.

[0004]

In the above-mentioned conventional port ladder, since the waffladder device is a separate body, the work of bridging the waddladder device on the sea is complicated. Therefore, it is preferable to always attach a wad ladder to the berth side so that it can be swung to the quay side as necessary, but the wad ladder can be made compact without obstructing the rotation adjustment of the lower platform. Must be storable.

[0005]

According to the present invention, a lower platform is provided at the lower end of a ladder main body so as to be rotatable about a horizontal axis, and a turntable rotatable about a vertical axis is provided above the lower platform. The turntable is attached to the turntable so as to be able to be housed in the ladder body in a piled manner so that it can be vertically swung around a horizontal axis, and the horizontal axis of the word ladder and the horizontal axis of the lower platform during storage are arranged on substantially the same axis. By doing so, the above problems are solved.

That is, when the rotation of the lower platform is adjusted during storage of the warf ladder, since the horizontal axis of the lower ladder and the horizontal axis of the lower platform are arranged on substantially the same axis, the turntable also moves along with the lower platform. It is pivoted, so that the pivotal adjustment of the lower platform is not impeded. In addition, since the wafflador is stored in a superposed manner on the deck main body, the storage space becomes compact.

When using a war ladder, for example,
The winch provided on the turntable slightly raises the wad ladder through the wire rope, and in that state the turntable is swung to swing the wad ladder toward the quay side, and the wire rope is paid out to lower the wad ladder and set on the quay. This series of operations can be performed easily and quickly because the waffladder is attached to the side of the ladder in advance.

In the present invention, the lower platform may have any structure and shape as long as it can support the turntable. In addition, "almost on the same axis" includes those in which the two axes are completely coincident with each other, and in the retracted state of the waddler, the axis of the horizontal axis of the turntable and the waddle can be integrally rotated. May be out of alignment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. The ladder main body has a pair of left and right supporting columns, and locking rails are provided on the left and right supporting columns, and hooks that engage with the locking rails are provided on the left and right side portions of the waffladder. When storing in the main body in a superposed manner,
By engaging the hook with the locking rail, the displacement of the waddle ladder is prevented. In addition, the lashing rope stretched between the left and right locking rails can be used to fix the waddle ladder to the ladder main body. The locking rail may be formed over substantially the entire length in the longitudinal direction of the side ladder main body,
Also, it can be provided only at a portion corresponding to the hook.

If a winch that swings up and down by pulling up the waffladder with a rope is provided on the turntable, the winch is operated when the wafflador is swung to the quay side or stored on the side ladder main body. The turntable can be easily swung up and down by hoisting and unwinding the rope, and the installation work can be further facilitated and speeded up. If the winch is a manual winch, the structure can be simplified and the cost can be reduced, but a winch driven by a motor or the like can also be adopted. Further, it is preferable to use a wire rope as the rope from the viewpoint of ensuring durability and strength.

If the waffladder is detachably attached to the turntable, for example, when the ship is moored at sea and uses the side ladder device of the present invention to get on and off a small boat, the waddladder is turned. By removing the wad ladder from the table and leaning it against the railing of the starboard main body to fix it, the starboard main body can be used.
