Abstract

PURPOSE:To securely draw up an anchor without hitching on a water bottom by rotatably supporting an anchor craw on a rotary support board. CONSTITUTION:When throwing an anchor craw 1 into a water bottom, the anchor craw 1 is made a locked condition by means of a lock plate 2 installed on a long hole 8 for sliding formed on the anchor craw 1 and, then, an anchor body is thrown into the water bottom, with a lope 11 in hand. A rope 10 for making the lock plate 2 free is connected to the lock plate 2. In order to draw up an anchor which is hitched on a water bottom, the rope 10 is pulled from above a ship, to pull out the lock plate 2 up to a stopper 9 along the sliding long hole 8, thereby, making the anchor craw 1 free, and the anchor can be released from the hitched condition.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an anchor used for mooring a ship.

(Prior art) Originally, an anchor stops a ship by hooking the hook to the bottom of the water due to the weight of the anchor itself. For this reason, anchor hooks are inherently heavy, and in small vessels in particular, the anchor must be pulled up from the water's bottom by hand.
Retrieving it required a lot of effort. Also, while an anchor with a large claw that has a strong grip can reliably stop a ship, it also has the disadvantage that if it gets entangled in a protrusion on the bottom of the water, the anchor will drag, making recovery work even more difficult. There were many.

(Purpose of the Invention) The present invention has been made for the purpose of solving the following disadvantages, and is characterized by the fact that the anchor can be easily and reliably pulled up and recovered without the anchor being stuck to the bottom of the water. The purpose is to provide.

(Structure of the Invention) In order to achieve this object, the anchor claw is rotatable, and the anchor claw is rotatable by a rotation support plate having a guide bolt, a rotation shaft bolt, a long hole for rotation Φh, and a guide rail. Support configured.

The drawer has a hole for the slide to release the anchor claw from the 0771 step, and a lock plate is installed in it.

A pull-out rope is connected to the lock plate, and the anchor claw is released from the lock stage F by pulling the lock plate to the stopper via the pull-out rope.

The stopper is made up of two plates connected, and the long slide hole is extended to the plate on the anchor claw side, which is an extension of the long slide hole, so that the lock plate in the anchor shaft can be removed by separating. It is set up.

In this way, the drawing shaft of the anchor has an anchor claw locking means and a cicada releasing means, and is configured so that the lock plate can be attached and detached.

(Example) When the anchor (Fig. 4) with the anchor claw 1 in the released state is cast to the bottom of the water, the lock plate 2 attached to the elongated slide hole 8 on the anchor shaft 4 is slid. Insert it into the guide rail 12 along the elongated hole 8 for the anchor claw, push it into the end of the elongated hole 8 for the anchor claw side slide, and put the anchor claw 1 in the locked state as shown in Figures 1, 2, and 3. Take 0771 steps so that If you drop it in such a way that it hits the anchor directly, the anchor's 1
1t, the lock plate 2 is pulled out via the pull-out rope 10, and the anchor claw 1 reaches the bottom of the water in a released state as shown in FIG. 4, making it impossible for the anchor to perform its original purpose fully, so care must be taken. In addition, even after reaching the bottom of the water, the pull-out rope 10 used for pulling up and recovering the anchor is always kept in a free state, and only the pull-out rope 11 is used to move the vessel to the 8th line.
Moor as shown.

Next, by purchasing a locking means and pulling up and recovering the anchor that is rooted to the bottom of the water, the pulling rope 10, which is connected to the lock plate 2 in a free state, is towed from the ship. The lock plate 2 is connected to the guide rail 12 and the slide slot 8 in the anchor shaft 4 through the lock plate 2.
The anchor claw 1 shown in FIGS. 1, 2, and 3, which is in the locked state, is released from the locked state. The released anchor claw 1 pulls the boiling rope to the ship.
By pulling from L, the rotation shaft bolt 6 of the rotation support plate 3 having the long rotation hole 7 rotates together with the guide bolt 5 along the rotation long hole 7, and it is easily entrenched. When the anchor is released from the locking means shown in Figure 4, the anchor can be pulled up onto the ship and recovered.

(Effects of the Invention) (1) As described above, the present invention allows the rotatable anchor claw to be released from the locking means by towing the pulling rope from the ship, and the anchor on the bottom of the water can be easily moved without being entangled. One can quickly and reliably recover the ship.

(2) Also, by having anchor claws with different gripping forces and shapes, they can be used depending on the right material, the right place, and the situation at the time.

(3) This anchor is disassembled and can be disassembled and stored compactly on board.

Claims (3)

[Claims] (1) The anchor shaft is composed of a lock plate that releases the anchor claw from the locking means and locks it from the release, a sliding slot that slides the lock plate, and a stopper that stops the slid lock plate in a fixed position. To release the anchor claw from the locking means, a pull-out rope is connected to the lock plate. By pulling the pull-out rope from the ship, the lock plate slides along the elongated sliding hole to the stopper, and the anchor claw is released from the locking means. An anchor characterized by releasing. (2) The stopper consists of two plates connected and is attached to the anchor shaft. By separating this stopper, the lock plate in the anchor shaft can be attached and detached, so that the long slide hole is extended from the slide hole to the anchor claw side plate. Patent claim No. 1
Anchor as described in section. (3) The anchor claw is rotatable and supported by a rotation shaft bolt, a guide bolt, an anchor claw support plate having a rotation slot and a guide rail. The anchor claw released from the locking means is characterized in that it rotates together with the guide bolt around the rotation axis bolt along the rotation slot.
