Description

  The present invention relates to a handrail in a ship, and more particularly to a movable handrail for making it difficult for a pirate to enter a ship.

In recent years, pirate incidents have frequently occurred in straits such as Southeast Asia and Latin America. Pirates are a fully armed group, and may take the crew's money, cargo, or ships, and the countermeasures are difficult.
There are cases where pirates climb up the anchor chain while the ship is anchored, and cases where the anchored rope is thrown up, the anchor is hooked on the handrail of the ship, and a rope ladder is climbed up based on this. is there.

  For pirates climbing along the anchor chain, a hose / pipe, which is a passage through which the anchor chain goes out of the ship, is covered and a means for blocking the entrance is taken. However, for a pirate climbing with an anchor, when a pirate is detected, a siren is sounded and the ship is moved backward. Various measures have been taken, such as water discharge and throwing back anchors, but fully armed pirates are opponents, and there is a limit to the response of these crews, both of which are reliable and effective means. There wasn't.

  In particular, for a vessel that is sailing at night, a small vessel from behind and sniffing an anchor, and if a pirate coming in at a stretch is delayed in detection or missed the approach, it will be boarded shortly before taking countermeasures, There is no way to deal with a fully armed pirate.

  To cope with this situation, the trigger is automatically rotated when the anchor is caught by the anchor attached to the support side of the handrail, protruding from the handrail attached to the support column, and turning on the ship side. In addition to increasing the distance between the rope and the ship side skin, it is difficult to climb, and a trigger rotation detection mechanism is provided, and the hot water supply pipe opening / closing valve is opened by the detection signal of this rotation detection mechanism to release the hot water. A method of repelling pirates has been considered (for example, see Patent Document 1).

However, in this method, when the anchor is unfortunately caught on the handrail attached to the column or on the bar part under the trigger, the trigger may not rotate or the rotation may not be sufficient. May occur.
Also, the trigger is usually held by a spring, but when a force is applied, it will rotate against the spring, and when the crew inadvertently leans against the handrail during normal times, the trigger There is a concern that will rotate. Furthermore, since it is the structure which attaches a trigger to a handrail, it has become a structure which the cost increases as the whole handrail.

Japanese Patent Laid-Open No. 2002-37179 (Pages 1, 2 and FIGS. 1 and 2)

  The present invention solves the above-mentioned problems, makes it more difficult for pirates to enter, and is always locked and securely locked in an upright position, and locked when it reaches the pirate's advancing waters. The purpose is to obtain a movable handrail that can be tilted by removing.

A movable handrail in a ship, which is a pivotable handrail post, a handrail spanned between the handrail posts, a lock means for fixing the handrail post in an upright position, and a handrail A handrail unit composed of supporting means for holding the tilting position of the column is connected to the ship's circumference on the deck.
In addition, the adjacent handrail units are connected with a flexible rope. In addition, a tilt detection switch for detecting the tilt of the column is provided.

  The handrail post can be locked and fixed, and it can be tilted by releasing the lock, so it can be used as a safe handrail by always fixing the handrail post in an upright position and can be tilted when the lock is released. If it becomes a rail and a pirate tries to climb with an anchor, the handrail tilts, making it difficult for the pirate to enter.

  In addition, since the handrail has a unit configuration, the handrail only tilts where the pirate attempts to enter, and easily tilts with the weight of the pirate alone. Pirates can be detected by the tilt detection switch, so it is possible to take countermeasures quickly. Moreover, since the handrail itself is tilted with a simple configuration, the entire handrail can be configured at low cost.

  The best mode of the present invention shown in the drawings will be described below. 1 is a schematic perspective view of a handrail according to the present invention, FIG. 2 is a schematic side view of the handrail, FIG. 3 is a front view as seen from the arrow A in FIG. 2, FIG. 4 is a front view as seen from the arrow B in FIG. 5 is a schematic view showing another embodiment of the handrail according to the present invention.

  In the figure, 1 indicates a hull and 2 indicates a handrail unit. 3 is an upper deck and 4 is a ship side outer board. Reference numeral 5 denotes a handrail mounting plate (hereinafter simply referred to as mounting plate) mounted on the upper deck 3, and a handrail column (hereinafter simply referred to as column) 7 is rotatably attached to the mounting plate 5. Has been. The column 7 is provided with tilting position holding means, and can tilt only a predetermined range from the upright position.

  The handrail unit 2 is composed of two struts 7, a handrail 12 spanned between the struts 7, locking means for fixing the struts 7 in an upright position, and tilting position holding means for the struts 7. Therefore, the tilting of the column 7 means that the entire handrail unit 2 is tilted. The handrail unit 2 is continuously connected to the stern on the upper deck 3 from the stern part where the pirates aim to invade to the ship side.

  Reference numeral 9 denotes a tilt position holding member, one end of which is fixed to the support column 7 and the other end is fitted with a pin 10 fitted in a guide groove 6 provided in the mounting plate 5 to be a free end. . When the column 7 is upright, the pin 10 of the tilt position holding member 9 is at the lower end of the guide groove 6. When the stopper 11 that can be inserted into and removed from the pin 10 is applied at this position, the column 7 is fixed in the upright position. Is done.

  When the stopper 11 is removed, the column 7 can be tilted. When the support column 7 is tilted to the outer side of the ship, it is pulled by the support column 7 so that the tilt position holding member 9 also protrudes in the lateral direction, but the pin 10 of the tilt position holding member 9 is the top of the guide groove 6. At this point, the overhang of the tilt position holding member 9 is stopped, and the tilt of the support column 7 is also stopped. That is, the column 7 is held in a tilted posture at this position.

  Handrails 12 are provided between the support rails 7 of the handrail unit 2, and adjacent handrail units 2 are connected by a flexible rope 13 such as a chain. Therefore, the handrail 12 is effective as a handrail when the handrail unit 2 is fixed (normally), and when the column 7 is tilted, the handrail unit 2 is erroneously inserted between the adjacent handrail units 2. In order to prevent people from falling, they are protected by the rope 13.

The mounting plate 5 is provided with a tilt detection switch 14 that is switched by the displacement of the tilt position holding member 9 in order to detect the tilt of the column 7. An alarm is issued from the speaker 15 by the operation of the tilt detection switch 14. That is, by detecting the tilt of the support column 7, it is possible to quickly detect the invasion of the pirate.
Although not shown, the operation of the tilt detection switch 14 can be linked to searchlight irradiation and pirate repelling steam injection.

  FIG. 5 shows another tilt position holding means of the column 7. In this example, a stopper 16 is provided that contacts the support column 7 to stop the tilting and holds the support column 7 at that position. Moreover, in order to fix the support | pillar 7 to an upright position always, the locking tool 17 is provided. In this case, the tilt detection switch 14 is mounted so as to be directly switched by the displacement of the column 7. The stopper 16, the locking tool 17, the stopper 18, and the like are appropriately provided on the mounting plate 5 and the deck 3. Reference numeral 18 denotes a stopper at the upright position of the column 7.

  Since the present invention is configured as described above, the pirate tilts the handrail unit 2 where the anchor tries to invade the handrail 12 and makes it difficult for the pirate to climb the rope or rope ladder. It can quickly detect situations where pirates are trying to break in and take appropriate action.

  It should be noted that when the lock means for fixing the support column 7 in the upright position is removed, it is necessary to prevent the support column 7 from being tilted by its own weight due to the hull swaying. For this reason, although not shown in the figure, when there is no external force applied to the pirate climbing on the anchor, the column 7 is urged to the upright position, and the pirate climbs by hooking the anchor on the handrail 12 There is provided an urging means for tilting the column 7 against the urging force when an external force is applied.

The schematic perspective view of the handrail by this invention. The schematic side view of the handrail. The front view by A arrow of FIG. The front view by the B arrow of FIG. Schematic which shows another form.
