Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor used for a ship that navigates the sea, lakes, rivers and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 12, an anchor body 43 in which an anchor claw 42 for engaging with a hooked portion at the bottom of a water is fixed to an anchor box portion 41 having a substantially semi-cylindrical shape and the anchor box portion. An anchor 45 including an anchor trunk 44 rotatably connected to a substantially central portion of 41 is well known. When the anchor 45 is not used, that is, when it is stored in a ship, the anchor 45 has a substantially flat shape as a whole and is very compact and does not take up a storage space. Further, since the anchor trunk 44 rotates in the arrow D direction during use, when the anchor trunk 44 is pulled by the cord 46 (in the arrow E direction) as shown in FIG. 13, the anchor trunk 44 causes the anchor box 44 to move. By being locked to the locking portions 41a and 41b provided on the portion 41, the anchor trunk
Since the rotation of 44 is suppressed, one side of the anchor claw 42
42a or the other surface side 42b and the anchor trunk 44 have a predetermined angle α (the angle at which the anchor claw 42 is most easily hooked to the hooked portion at the bottom of the water) and is generally V-shaped in a side view. The anchor claw 42 is surely hooked to the hooked portion 47 on the bottom of the water.

[0003]

However, when pulling up the anchor 45 as described above, there are many cases in which the anchor claw 42 is overly hooked on the hooked portion 47 and cannot be easily removed. In particular, it is remarkable if the hooked portion 47 is a rock or the like. In this case, the anchor 45 is pulled by changing the position of the vessel, or the anchor 45 is pulled out by using the propulsive force of the vessel, but if it still does not come out of the hooked portion 47, the cord 46 is pulled. It was cut off and the anchor 45 was thrown to the bottom of the water.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to securely anchor the hooked portion on the bottom of the water to anchor the vessel and to easily pull up the vessel when moving. The challenge is to provide possible anchors.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. Means for solving the problem is an anchor capable of being hooked on a hooked portion 28 at one end side. An anchor trunk 9 to which a cord 25 can be attached is rotatably connected to the other end of the main body 1, and the anchor main body 1 and the anchor trunk 9 can be hooked on the hooked portion 28.

In FIGS. 1 and 2, reference numeral 1 denotes a thick bottom plate 2 having a substantially rectangular shape in a plan view, and two side plates 3 having a substantially isosceles triangular shape in a side view, which are arranged substantially vertically with a predetermined interval. It is fixed, and from the substantially central part of the rear part 3a of the side plates 3, 3 to the front part 3b.
An anchor main body in which an anchor wing 5 having a substantially trapezoidal shape in a plan view is fixed substantially vertically to each other and an anchor claw 6 for engaging with a latched portion is projected in front of the front portion 3b.

Further, an anchor wing 5 is provided on the rear portion 3a of the side plates 3,3.
Holes 4 are drilled on the extension lines of. Further, rounded portions 7 are formed in a generally arcuate shape in a side view on the hypotenuses 15 above the rear portions 3a of the side plates 3, 3, and plate-shaped reinforcing members 8 are fixed along the rounded portions 7, respectively. There is.

Reference numeral 9 indicates an inverted V-shaped anchor trunk (shank) in which a bent portion 10 is formed on the rear portion 9a of the rod-shaped body, and further, in the approximate center portion near the rear end 9e of the anchor trunk 9. A hole 13 having the same diameter as the hole 4 is formed. Further, the rear portion 9a of the anchor trunk 9 is loosely fitted inside the side plates 3 and 3 arranged side by side, and the stock 11 is fitted into the holes 4 and 4 of the side plates 3 and 3 and the hole 13 of the anchor trunk 9. The anchor trunk 9 is connected to the anchor body 1 so as to rotate.
A ring 12 is provided on the front portion 9b of the anchor trunk 9.

The locking means A is composed of the following first link body 14 and roller 19. That is, reference numeral 14 denotes a pair of side-view substantially rectangular link bodies whose one end side is rotatably connected to the stock 11, and a core rod 17 is attached to the other end side of the first link bodies 14, 14. Moreover, a roller 19 around which a rubber body 18 having an elastic force is provided is rotatably provided on the core rod 17. The roller 19 is in contact with the oblique side of the rear portion 3a of the side plates 3 and 3, that is, the rolling surface 15, and can roll on the rolling surface 15.

Furthermore, when the bent portion 10 of the anchor trunk 9 is in contact with the bottom plate 2, the contact point between the center of the stock 11 and the roller 19
The distance to 15a is minimum (hereinafter referred to as home position), and the distance increases in the direction of the upper end 3c of the side plates 3,3, and becomes the maximum at the upper end 3c.

That is, the roller 19 is pressed in the direction of the upper end 3c by the rotating anchor 9, and the stock 11
Although it is configured to roll on the rolling surface 15 of the side plates 3 and 3 while drawing an arc centering on the center, as described above, the upper end 3c of the side plates 3 and 3 is
Since the distance increases in the direction, the roller 19 having an elastic force is firmly pressed and urged against the rolling surface 15. Therefore, the roller 19 does not deviate from the home position in a normal state, and the rotating anchor 9
Can be held within the angle α that can be hooked on the hooked portion 28 shown in FIG.

Reference numeral 20 denotes a fixed shaft fixed to the front of the bent portion 10 of the anchor trunk 9, which is fixed substantially at right angles to the anchor trunk 9.
Reference numeral 21 denotes a pair of second link bodies each having one end side rotatably connected to the fixed shaft 20 and having a substantially rectangular shape in a side view, and a long hole 22 is formed at the other end side of the second link body 21. The elongated hole 22 is loosely fitted in the core rod 17.

The stock 11, the core rod 17, and the fixed shaft 20.
Since the nut 23 is provided in the first link body
14 and the second link body 21 do not come off. Furthermore, 2
A connecting plate 24 is fixed to the one anchor claw 6 as a reinforcing material.

The case where the anchor of the present invention having the above-mentioned structure is used for a ship which sails at sea will be described below.
As shown in FIG. 3, the rope 12 is tied to the ring 12 as a cord and the tidal current 26 flows in the bottom plate 2 (direction of arrow A in FIG. 3).
When the anchor is struck toward, the bottom plate 2 with a thick wall thickness, that is, a heavy weight, goes down, and the ship (not shown) sinks to the bottom of the water 27 while being swept by the tidal current 26 in the direction of arrow a. .
Therefore, when the anchor reaches the water bottom 27, the rear end 2e of the bottom plate 2 and the front end 6d of the anchor claw 6 contact the water bottom 27 and land.

Then, as shown in FIG. 4, the anchorage 9 is lifted up with the stock 11 as a fulcrum by the tensile force of the mooring rope 25, and the elongated hole 22 of the second link body 21 is moved along the core rod 17. When the core rod 17 reaches the front end 22d of the long hole 22, the roller 19 at the home position makes a predetermined angle α with the anchor body 1 via the second link body 21.

The anchor trunk 9 is rotatable up to a predetermined angle α, and the predetermined angle α is the anchor claw of the anchor main body 1.
The angle 6 is the most easy to hook on the hooked portion 28 (ground, rock, etc.) of the water bottom 27, and this angle can be arbitrarily changed depending on the length of the long hole 22. It should be noted that the anchor cannot be hooked on the hooked portion 28 unless the anchor trunk 9 and the anchor body 1 form the angle α, and can be hooked within this angle α. Then, the rear end 2e of the bottom plate 2 separates from the water bottom 27, and the anchor claws 6
The front end 6d of the anchorage rope 25 is approximately in the pulling direction (arrow B direction)
Since it moves to, the anchor claw 6 hooks (bites into) the hooked portion 28, and the anchor works and the ship can be anchored. In this way, when the anchor body 1 is pulled in the direction in which it is hooked on the hooked portion 28, the pulling force mainly acts in the direction in which the anchor claw 6 hooks on the hooked portion 28. It has almost no effect on 19. Therefore, when the anchor body 1 is hooked on the hooked portion 28, the roller 19 does not roll and the anchor trunk 9 is locked at a predetermined angle α.

Next, when the anchor is pulled out and the anchor does not come out easily, the anchored vessel is moved to a position substantially opposite to the anchoring position and the tether rope 25 is pulled, A rotation force is applied to the anchor 9 of the anchor to widen a predetermined angle α. Then, when the turning force in the direction of expanding the predetermined angle α becomes stronger than the urging force of the roller 19, the roller 19 is pushed by the anchor 9 and moves on the rolling surface 15 of the side plates 3, 3 toward the upper end 3c thereof. Rolling while pressing and deforming the rubber body 18, and further, by pulling the anchor trunk 9, the roller 19 gets over the upper ends 3c of the side plates 3 and 3 and separates from the rolling surface 15, and the side plates 3 and 3 By moving to the rear end 3e, the anchoring of the anchor trunk 9 is released, and the anchor trunk 9 becomes rotatable beyond a predetermined angle α. (Two-dot chain line shown in FIG. 5)

Then, as shown in FIG. 6, since the anchor trunk 9 and the anchor main body 1 are substantially linear, pulling the anchoring rope 25 causes the anchor main body 1 to move in the direction opposite to the locking direction of the anchor claw 6. Since the anchor is pulled, the anchor body 1 can be pulled out from the hooked portion 28 very easily. When using the anchor again, when the anchor trunk 9 is rotated in the direction of the anchor claw 6, the anchor trunk 9 and the roller 19 are connected by the second link 21.
Roller 19 moves over the upper end 3c of anchor body 1 together with 9
Return to 15. That is, by simply forcibly rotating the anchor trunk 9 in the direction of the anchor claw 6, the anchor 9 returns to the home position and is ready for use again.

In the above embodiment, as the locking means A for locking the anchor 9, a roller 19 having a rubber body 18 around a core rod 17 is wound around the stock 11 by the first link body 14. Although it is configured to be movably connected, it is not necessarily limited to the above-described configuration, and a spring 30 having an elastic force is used instead of the first link body 14 as shown in FIGS. 7 and 8. Good.

That is, both ends of the spring 30 are formed in an annular shape, one end of which is loosely fitted in the stock 11 and the other end of which is loosely fitted in the core rod 17. The roller 31 is strongly attracted toward the stock 11 by the spring 30 and constantly presses and urges the rolling surface 15 of the side plates 3 and 3 so that the roller 31 is not easily displaced from the home position. Therefore, as in the above embodiment, the anchor trunk 9 can be held at the predetermined angle α.

Further, when the anchor trunk 9 is pulled so as to rotate by a predetermined angle α or more, the spring 30 extends and the roller 19 gets over the upper ends 3c of the side plates 3,3. In this case, the roller 19 may or may not be provided with the rubber body 18. Therefore, a metal roller 19 may be used, in which case the rubber body 18
There is no need to replace the roller 19 due to damage or abrasion of the roller.

Further, in the above embodiment, the anchor trunk 9 is configured to rotate only on one side of the anchor main body 1, that is, on the side where the bottom plate 2 is not provided. For example, as shown in FIG. 9 and FIG. As described above, the structure may be such that the anchor body 1 rotates to both sides. That is, the substantially straight anchor 9 is rotatably connected to the stock 11, and the side plate connecting member 34 is fixed to the rear ends 3e of the side plates 3,3.

One end of the spring 30 is loosely fitted to the core rod 17 of the roller 19 having a small diameter provided on the one surface 1a and the other surface 1b of the anchor body 1, and the other end of the spring 30 is loosely fitted to the stock 11. The roller 19 is pulled toward the stock 11. Unlike the above embodiment, the bottom plate 2, the connecting plate 2
4, the first link body 14, the second link body 21, and the fixed shaft 20 are not provided.

Since the anchor trunk 9 is rotatable toward the one surface 1a or the other surface 1b side of the anchor body 1 (two-dot chain line shown in FIG. 10), the anchor of this structure has the one surface 1a or the other surface 1b side. There is an advantage that the hooked portion can be reliably locked regardless of which of them faces the water bottom.

Further, as shown in FIG. 11, the side plates 3, 3 at the home position of the roller 19 may be provided with a substantially arcuate notch 35. By fitting the roller 19 to the cutout portion 35, the roller 19 can be attached to a hooked portion or an obstacle.
Will not be accidentally detached to the rear end 3e side of the side plates 3,3.

Further, although the mooring rope is used as the cord in the above embodiment, the cord is not necessarily limited to the mooring rope, and may be, for example, a wire rope, a rope of natural or synthetic fiber, a chain, or a metal. It may be a chain or the like. What is important is that the anchor can be moored.

[0035]

According to the anchor of the present invention, when the anchor main body hooked on the hooked portion cannot be easily lifted up, the anchor trunk is pulled through the cord, so that the anchor trunk is locked. Rotational force capable of rotating more than the angle capable of being hooked is applied to the stop portion, and the locking of the locking means is released, so that the anchor trunk becomes rotatable.
Therefore, the anchor main body and the anchor trunk are substantially linear, and the anchor main body can be pulled out in the direction opposite to the direction in which the anchor body is hooked, so that the anchor can be pulled out from the hooked portion very easily. Because it is possible, there is no need to throw away the anchor as in the past, which is very economical.

Further, as an effect of the means according to the second aspect, the locking means is provided on the link body connected to the anchor body and on the first link body so as to be rotatable, and the locking body is rotated. A roller having an elastic force that presses and rolls the moving surface, and the first link body is rotatably provided with respect to the anchor main body, so that the anchor main body and the anchor trunk are The roller is elastically deformed by holding a hooking angle at the hooking portion and applying a turning force capable of rotating the anchor trunk to the above angle or more, and the roller disengages from the rolling surface of the anchor body. At the same time, the anchor trunk can be rotated more than the above angle, the anchor body and the anchor trunk are in a substantially linear shape, and the anchor body can be pulled out in the direction opposite to the direction in which it is hooked on the hooked part, so it is extremely The anchor can be easily pulled out from the hooked part. By pressing the roller against the rolling surface by the spring as in the means described in claim 4, the roller does not need to have an elastic force, and therefore the durability of the roller can be improved.

Further, as an effect of the means described in claim 3, one end of the second link body is connected to the anchor trunk, and the elongated hole formed at the other end of the second link body is provided with the above-mentioned. Since the core rod of the roller is loosely fitted, the anchor trunk is rotatable between the elongated holes, and the range of the angle at which the hooked portion can be hooked can be arbitrarily changed. Therefore, since the anchor body and the anchor trunk are generally flush with each other and do not form an angle, they are flush with each other and do not occupy a storage space.In use, the anchor trunk rotates by the length of the long hole, and It is possible to form an angle at which the hooked portion can be hooked on the hooked portion. In addition, since the anchor trunk and the roller are connected by the second link,
After the anchor trunk is separated from the rolling surface of the anchor body as described above, when the anchor trunk is returned to its original position, the rollers also return to their original positions at the same time,
It can be used again.

Further, as an effect of the means according to claim 5, the roller has a notch portion by forming a notch portion on the rolling surface of the anchor body into which the roller fits when the angle is less than the angle. It will be hooked, the roller will not be caught by any obstacle, and the roller will not accidentally come off the rolling surface.
