Abstract

PURPOSE:To dispense with the formation of a hook on an anchor by forming a yoke for sandwiching on the lower portion an anchor cable in an annular fitting which is connected to a float and through which the anchor cable can pass freely and mounting a swingable anchor cable stopper having the adjustably expansible length. CONSTITUTION:An annular fitting 1 connected to a float through a rope 3 to allow an anchor cable 5 to pass through said fitting is provided swingably with an anchor cable stopper 2 through a shaft 8. The anchor cable stopper 2 has an adjustable length and is formed on the lower portion with a yoke for sandwiching the anchor cable 5. The anchor cable 5 is pulled by a ship up to a position of an annular fitting engaging a float. Then, when the anchor cable 5 being pulled by the ship is stopped, the anchor cable 5 is engaged by the lower yoke of the anchor cable stopper 2 and the annular fitting 1 so that the operation of pulling up the anchor by a small ship can be simply carried out. This dispenses with the prior formation of a hook on the anchor so that the constitution and handling of the anchor can be simplified.

Description

[Detailed description of the invention] M industry-0! The present invention relates to an anchor suspension shell used for pulling an anchor using the ship's power and pulling it up close to the water surface in a small ship that does not have an anchor pulling machine. In particular, the anchor is suspended in the water by a float near the water surface, and a stopper mechanism is provided to prevent the anchor line from slipping off.

Horsefly - Rice Φ - Technology - Generally, large ships have an anchor pulling machine, that is, a winch with an engine, so that they can pull and raise the anchor mechanically, but small ships are not equipped with such a mechanical anchor pulling device. Therefore, all the work of pulling and lifting the anchor must be done manually, which requires a great deal of labor and time. Therefore, in order to reduce the labor and time required for pulling and lifting anchors on small vessels, a ring-shaped metal fitting is passed through the anchor rope connected to the anchor when pulling and lifting the anchor, and the anchor is attached to the metal ring. In some cases, a float with buoyancy that can be suspended is attached, the vessel is sailed, and the anchor is hoisted close to the surface of the water. In this case, while the ship is moving, the float is floating near a predetermined water surface, so the anchor can move underwater until it is close to the float. When the anchor reaches the vicinity of the annular metal fitting, the hook metal fitting provided near the end of the anchor can be hooked onto the annular metal fitting. Therefore, when the hook fitting and the annular fitting are engaged, the anchor is fixed to the float and suspended in the water, so even if the ship stops moving and the rope becomes slack, the anchor will not fall to the bottom of the water again. Ropes, floats and anchors can be brought into the vessel.

That is what it is.

However, in the conventional anchor pulling method described above, it is necessary to attach a hook fitting near the end of the anchor, so the anchorer himself has to hook the hook fitting when dropping the anchor. It is dangerous because it can get caught on people's clothes or get caught on their clothes, and it has the drawback that care must be taken when handling it. Further, there is a problem that the hook metal fitting cannot necessarily be engaged with the annular metal fitting in many cases, and anchoring fails.

Same JUAi! The present invention is intended to solve the above-mentioned problems, and includes an annular metal fitting that has a connection part with a predetermined float and can be used to attach and detach an anchor line, and the annular metal fitting. To provide an anchor underwater suspension support comprising a yoke part which is pivotally fixed in the vicinity of a connection part with the float, extends in the radial direction of an annular metal fitting, is extendable and swingable, and holds an anchor rope between the yoke parts.

Effect 1 According to the above configuration of the present invention, when pulling the anchor out of the water bottom and then lifting the anchor, the annular metal fitting connected to the float is engaged with the anchor rope, while the anchor rope is held between the yoke part. When the ship descends to the surface of the water and moves, the anchor rope is pulled, the anchor is raised, and the anchor claw detaches from the bottom of the water.The anchor rope is then pulled further, and the anchor becomes a ring-shaped metal piece suspended in the water by a float. Using this as a fulcrum, it rises to near the water surface. After the anchor is lifted, the ship stops sailing, the anchor rope becomes slack, and the anchor rope is pulled in the opposite direction by the anchor's own weight in order to prevent the anchor from descending to the bottom of the water again. The rope is pressed against the annular metal fitting to act as a stopper and stop the anchor from descending, keeping it suspended in the water.

Parental loss case The present invention will be described below with reference to illustrated embodiments.

Fig. 1 is a front view showing an example of the anchor underwater suspension support according to the present invention, Fig. 2 is a left side view thereof, Figs. The figure is an explanatory diagram of the action when the anchor is suspended.

In FIGS. 1 and 2, ▪ is an annular metal fitting, and 2 is a yoke portion. The annular fitting 1 is made by bending a steel rod having a predetermined diameter into the shape of a safety pin, and has a substantially oval shape with @1 at one end.
A loop-shaped connecting part 4 is formed to connect to a float 15 having a buoyancy capable of suspending the anchor rope 2 in water, and a stop part 6 is formed to open and close the annular fitting 1 in order to engage and disconnect the anchor rope 5 at a predetermined position. has been done. The connection between the annular metal fitting 1 and the float 15 is the float 15
This is done by inserting the rope 3 through the loop-shaped connecting part 4. The loop-shaped connecting part 4 is connected to the insertion end 6a of the stop part 6.
The insertion end 6a is engaged with the annular end 6b to prevent it from coming off against the force of the spring. On the other hand, in the yoke part 2, a cylindrical rod 9 is provided on a bracket 7 which is welded and fixed to a loop-shaped connecting part 4 so as to be swingable via a shaft 8.
is inserted, and this yoke rod 10 is configured to be expandable and retractable by means of a tightening screw 11. The yoke portion 2 extends on the center line C-c of the annular metal fitting 1. Also, yoke rod 1
0 has its tip bent toward the annular metal fitting 1 side, and when holding the anchor rope 5, the shaft 8 that pivotally supports the cylindrical rod 9 is the second one.
As shown in the figure, the number is outward from the center line D-D of the annular metal fitting 1;
The yoke portion 10 is biased toward the annular metal fitting 1 in the normal state.

Next, I will explain how to use this anchor underwater suspension support.
As shown in FIG. 3, if the small boat 14, which is stopped on the water surface WL with the anchor 12 hooked to the water bottom 13, does not move, first a float is attached to the annular fitting 1! 5 is connected, the stopper 6 is opened to engage the anchor rope 5, and the float 15 and the anchor rope 5 are thrown onto the water surface WL as shown in FIG. Then, the ship is moved in the opposite direction to the direction in which the hook of the anchor 12 engages with the water bottom 13. By doing so, the anchor rope 5 is pulled in the direction in which the anchor claw is removed from the water bottom 13, the anchor 12 is removed from the water bottom 13, and the anchor 12 is further pulled out from the water bottom 13. At this time, float 1
5 is submerged in water due to wave resistance during movement,
The buoyant force tries to pull up the anchor line 5 and promotes the separation of the anchor claw from the water bottom 13.

After the anchor 12 has been pulled out from the water bottom 13, if the small boat 14 is moved in a direction away from the float 15 as shown in FIG. It is pulled up near float 15 as a result. Therefore, when anchor 12 was pulled up near float 15, anchor 1II5
When the anchor 12 becomes slack, it attempts to descend toward the bottom of the water again.

However, at this time, as shown in FIG.
is pulled toward the bottom 13 by the weight of the anchor 12, causing the yoke portion 2 to swing toward the annular fitting 2, and the lead wire 5 is clamped and locked between the yoke rod 10 and the annular fitting 1.

Therefore, the lead wire 5 stops without slipping from the annular fitting l, and the anchor 12 is suspended by the float 15 and the water surface W[
, stop nearby. Note that this effect is effective only when the yoke part 2 is located between the annular metal j41 and the small boat 14, and if the yoke part 2 is located between the annular metal fitting 1 and the anchor 12. It will not work if it is located in the opposite position, so be careful when installing it. Note that if it is determined that the force of the yoke portion 2 pressing the lead wire 5 against the annular fitting 1 is weak, the tightening screw 1
1 and pull out the yoke rod 10 slightly from the cylinder rod 9 to adjust it. In this way, the anchor 12 is brought close to the float I5.
When the float is lifted up, the lead wire 5 is pulled together and the float 15 and #
112 is stored in the small boat 14. Therefore, anchor 1
2 from the water bottom 13 to the water surface can be omitted.

Young fruit of Hikari 1IJi - As explained in -■-, the present invention is capable of pulling the anchor close to the water surface by engaging the lead line and throwing it into the water together with the float when unloading and lifting the anchor, and moving the hull of the ship. A yoke part that can be lifted close to the float, and when the anchor is hoisted close to the float, even if the lead wire is sagged due to storage, the yoke part acts as a stopper to press the lead wire against the annular fitting and prevent it from slipping off. Since the anchor submersible suspension support is made of an annular metal fitting equipped with this, the labor required to raise the anchor from the water bottom to the water surface can be omitted, and it is extremely convenient for small vessels that do not have an anchor pulling or lifting device. Furthermore, the action of suspending the anchor in the water is
This is done by the automatic movement of the yoke that swings toward the annular metal fitting and presses the lead wire due to the movement of the lead wire, and there is no uncertainty such as when the hook attached near the tip of the anchor engages with the annular metal fitting as in the past. Since this is not done by a mechanical action, it is possible to reliably lift the anchor without causing failures in lifting the anchor, such as dropping the anchor to the bottom of the water once it has been lifted close to the water surface. Furthermore, since there is no need to attach a hook or the like near the tip of the anchor, the anchor is safe to handle, does not require special care, and is convenient.
