本発明は、船舶等の係留、停泊に用いる自動pツク解除
装置付路に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a road with an automatic lock release device used for mooring and anchoring ships and the like.
従来の船舶等を係留する錨としては、例えば、第9図と
第10図に示すような自在錨が用いられていた。すなわ

在に埋設されかつシャフトの半径方向外方に突出するよ
う弾性的に抑圧保持されるとともにスリーブの内周面に
より押圧されてシャフト内に没入するストッパー25に
より爪スリーブ23を保持するようになっている。As a conventional anchor for mooring a ship or the like, for example, a flexible anchor as shown in FIGS. 9 and 10 has been used. That is, in the conventional flexible anchor, a plurality of claws 22 are pivotally attached to the tip of the shaft 21 of the flexible anchor so that the shaft 21 can be opened and closed freely.
The claw sleeve 23 is slidably fitted onto the outer circumference of the claw 2.
2 and the claw sleeve 23 are connected by a plurality of links 24. Furthermore, a sleeve 26 is slidably disposed between the pivoting part of the pawl on the outer periphery of the shaft 21 and the pawl sleeve, and an operating rope 28 is connected to the sleeve 26. The pawl sleeve 23 is held by a stopper 25 which is elastically pressed and held so as to protrude outward in the radial direction of the shaft, and which is pressed by the inner peripheral surface of the sleeve and sinks into the shaft.

回収される。その後、爪22を折りたたんで所定箇所に
収納する。In the flexible anchor configured in this way, when the claw 22 is completely pushed open, the stopper 25, which had been recessed inside the shaft 21 by being pressed by the inner peripheral surface of the sleeve 26, protrudes from the outer peripheral part of the shaft, and the end surface of the claw sleeve 23 is pushed out. The pawl sleeve 23 is engaged with the pawl sleeve 23 to prevent movement thereof. In this state, the anchor is thrown into the sea and moored to a rock. When retrieving the free anchor, pull the operating rope 28 strongly from onboard to move the sleeve 26 onto the shaft 2.
1 to the raw silk 27 side, and the stopper 25 is recessed into the shaft 21. As a result, the claw 22
becomes free and by pulling the upper net 27, the flexible anchor is recovered on board the ship. Thereafter, the claw 22 is folded and stored in a predetermined location.

第8図(e)の状態とし、備前を完了するようになって
いる。なお、出船のときには、これと逆の順序により海
中より錨を回収して備前を解くようになっている。However, conventional anchors have the following structural problems. In other words, in general, the Bizen method for ships is as follows:
As shown in Figure 8 (a), the anchor attached to the end of anchor rope R1 was dropped into the sea from the bow, and as the anchor rope R1 was pushed out, as shown in Figure 8 (b).
, As shown in (C), move the ship S at a slow speed, stop the ship S in the state shown in Figure 8 (C), and check the effectiveness of the dropped anchor. When the state shown in Fig. 8(d) is reached, another anchor attached to anchor rope R1 is dropped from the stern into the sea, and the vessel is moved forward at a slow speed.
The state shown in FIG. 8(e) is reached, and Bizen is completed. Furthermore, when setting sail, the anchor is retrieved from the sea and the Bizen is released in the reverse order.
しかし、このような備前方法に従来の錨を用いた場合に

じ易かった。However, when conventional anchors are used in this Bizen method, the claws still firmly dig into the rocks, sand, etc. on the seabed, resulting in so-called blackboarding, which ultimately makes it impossible to retrieve the anchor from the ship. had become extremely difficult. In addition, mooring and retrieval of the anchor requires an anchor rope with two ropes, the upper net and the operating rope, and the structure of the anchor is somewhat complex, resulting in rust and tangles between the upper net and the operating rope. It was easy.
本発明は、錨の構造を簡素化し、かつ、−本のアンカロ

It consists of a locking member with a pivotally connected locking part, and a connecting rod that is loosely fitted into a bracket fixed to the main body and has a stopper formed at the rear end, and the tip of this connecting rod is pivotally connected to a pawl. At the same time, the stopper is engaged with the locking portion, and by pulling one anchor rope connected to the locking member, the engagement between the stopper and the locking portion is released.

た、その長さは水深の3倍以上の長さが必要とされる。Embodiments of the anchor with movable lock release device of the present invention will be described with reference to FIGS. 1 to 3. The anchor of this embodiment has a main body part 1
, a claw 21 (made of cast steel, for example) connected to the tip of the main body 1 via a connecting pin 7 so as to be able to open and close and pivot;
The lock member 3 is pivotally connected to the rear end of the lock member 3 via another connecting pin 8. Further, a bracket 6 is fastened to approximately the center of the main body 1 by a bolt 14, and two holes 6A are bored in the bracket 6 in parallel to the main body 1. A connecting rod 5 is loosely fitted into each of these holes 6A, and the tip of the connecting rod 5 is pivoted near the base end of the claw 2 via a pin 13, and the rear end of the connecting rod 5 is fitted loosely. A stopper 12 is fixedly provided to prevent the bracket from coming off from the bracket 6 and to engage with the locking portion 10. Further, the locking member 3 pivotally attached to the rear end of the main body 1 is formed of a substantially S-shaped arm and pivots about a connecting pin 8, and one arm has a locking portion 10 with a stopper 12; Further, a hole 9 is formed in the other arm portion to connect an anchor rope 4 for operation. The anchor rope 4 is made of synthetic fiber, cotton, linen, etc., and its length must be at least three times the depth of the water.
また、連結ピン7.8間の寸法は、係留する船舶の大き
さによって決めるようにしである。Further, the dimensions between the connecting pins 7 and 8 are determined depending on the size of the vessel to be moored.

4をたぐり寄せて船上に回収する。In this state, the anchor is thrown into the sea, and the tip of the anchor's claw 2 engages with rocks on the seabed, etc., as shown in Figures 4 and 6, and is temporarily fixed to the seabed. S can be moored at sea. In this case, the angle α of the anchor rope 4 with the seabed is 20 degrees or less. Next, when disengaging the anchor from the seabed and recovering the anchor onto the ship, a worker pulls one anchor rope 4 from the ship, takes in the anchor rope 4, and moves the ship S to the anchor anchoring position. When brought closer, the angle α of the seabed with the anchor rope 4 increases to β, and as shown in FIGS. The lock is automatically released when the anchor rope 4 is disengaged from the anchor rope 10, and while the ship S is moving forward, the anchor rope 4 is pulled in and recovered on board the ship.
本発明の錨は、以上説明したように構成されているので

を牽引するだけでよい。Since the anchor of the present invention is constructed as described above, when the claw is fully opened and the locking part of the locking member is engaged with the stopper, it has the same construction as a normal anchor, and when it is thrown into the sea as it is. The claws of the anchor dig into rocks on the ocean floor, allowing ships, etc. to be easily and securely moored. Additionally, when recovering the anchor, pulling one anchor rope disengages the stopper from the locking member and frees the claw, making it possible to easily and quickly recover the anchor on board without the anchor getting stuck. . Therefore, after being moored to the seabed, the anchor of the present invention is firmly fixed to the seabed even if the ship or the like is shaken violently by natural forces such as wind and waves, and will not come off the seabed unless the anchor rope is pulled. Never. Anchor rope 8 when the anchor becomes entangled or when pulling the anchor from the seabed.
All you have to do is tow it.
さらに、1本のアンカロープのみで錨の操作ができるの
