[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal mooring anchor which is excellent in mooring sand.

[0002]

2. Description of the Related Art As shown in FIG.
The T-shaped stock T is formed at the tip of the shank S which stands upright from the hook claw F so that the anchor is laid horizontally on the seabed, and the mooring chain C is attached to the stock T.
Is fixed and the stock T stops at the bottom of the sea (Fig. 4 (a)
), The hook claw F pierces the seabed and the shank S falls horizontally (see FIG. 4B).

[0003]

However, when a tensile force is applied to the mooring chain C, the stock T rises and the mooring force is affected by the hook between the hook claw F and the sea bottom. There is a problem that it is not possible to exert full mooring power. Therefore, in order to solve the above problem, the present inventor has focused on increasing the mooring force by installing an auxiliary anchor instead of the stock T. However, the mooring member is moored to the other end of the shank member as in the conventional case. It has been found that when the chain is directly attached, when the tension force is applied to the mooring chain C, the auxiliary anchor portion rises and the horizontal state cannot be secured. An object of the present invention is to provide a structure capable of ensuring a laterally mooring state in a laterally mooring anchor having a main anchor portion and an auxiliary anchor portion provided side by side via a shank member.

[0004]

SUMMARY OF THE INVENTION According to the present invention, in order to make the main anchor portion and the auxiliary anchor portion provided at both ends of the shank member laterally as much as possible, the mooring chain is attached to the main anchor portion and the auxiliary anchor portion. It was made paying attention to the importance of the relationship between the shank member (3) and
The number of arms (11) from one end of the shank member (3)
With a claw portion (12) at the tip
The main anchor part (1) and the main anchor part (1)
Shanks a plurality of arms (21) shorter than the arm (11).
Extending outwardly from the other end of the member (3) and
Auxiliary anchor part (3) having a claw part (22) at the tip
And an arm (23) extending outwardly on the side of the auxiliary anchor portion (2) of the shank member (3) .
On the main anchor part (1) side of the shank member (3).
Is engaged with one end of the mooring chain (4),
The part that continues to one end of the shank (4) is the shank member.
Separate from the shank member (3) toward the other end of (3).
So that the swing link extends to the tip of the arm (23).
The mooring chain engaged through (25)
(4) By pulling the other end diagonally from above,
The anchor part (1) and the auxiliary anchor part (2) are simultaneously drawn.
It is characterized by being pullable .

[0005]

According to the present invention, the mooring chain 4 engages with the main anchor portion 1 at or near the center thereof, while the auxiliary anchor portion 2 and the tip of the arm spaced apart from the center thereof. Since the engaging portion is engaged with the swing link 25 through the swing link 25, the pulling force from the mooring chain 4 accompanying the movement of the ship is largely divided toward the main anchor portion through the swing link 25, and the main anchor portion and the auxiliary anchor Not only it acts on the part 2 at the same time, but due to the component force in the direction of the main anchor part, the main anchor part changes to the shank member even at 45 to 60 ° which is more than the normal mooring angle (about 30 °) to the anchor of the mooring chain. As a result, the mooring action is exerted in a substantially horizontal direction along the auxiliary anchor portion. As a result, lateral mooring is secured and the mooring effect on the sand is significantly increased. On the other hand, when the mooring chain 4 is pulled up in the vertical direction, the main anchor portion 1 is pulled up after the auxiliary anchor portion 2 is raised, so that the pulling work is not hindered. Since the anchor including the main anchor portion and the auxiliary anchor portion is bulky during transportation and storage, it is preferable that the main anchor portion 1 and the auxiliary anchor portion 2 that are provided side by side via the bar member 3 can be separated from each other. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an exploded perspective view of a horizontal anchoring anchor according to the present invention, in which a main anchor portion 1 and an auxiliary anchor portion 2 are provided side by side via a shank member 3.

In the drawing, the main anchor portion 1 has four arms 11 of length L1 which extend in all directions at an angle of 90 degrees at the tip of the shank member 3 and whose tip bends upward by approximately 45 degrees. And a pentagonal claw blade 1 at its tip
2 is attached to the shank member 3 so as to be inclined slightly inward from substantially vertical. On the other hand, the auxiliary anchor portion 2 has an arm 21 having a length L2 shorter than that of the arm of the main anchor portion which also extends in all directions at the rear end portion of the shank member 3 and forms an angle of 90 degrees. Claw blades 22 are attached to the shank member 3 in the vertical direction except one.

The shank member 3 is separated in the vicinity of the main anchor portion 1, the short side portion 31 and the long side portion 32 thereof are fitted and assembled, and can be fixed by a screw 33.

The mooring chain 4 has one end attached to the short side portion 31 of the shank member 3 in the main anchor portion 1 and extends along the long side portion 32 of the shank member 3, and in the auxiliary anchor portion 2. A pin 24 is attached to the outer end of the stock 21 to which the claw blade 22 is not attached.
The swinging link 2 is attached to the tip of the fitting member 23 that is prevented from coming off by
It engages via 5, and is pulled up.

Therefore, when the above anchors are thrown into the sea, when the main anchor portion 1 stops at the bottom of the sea, they fall horizontally and become horizontal as shown in FIG.
Not only the claw blade 12 of No. 2 but also the claw blade 22 of the auxiliary anchor portion 2 bites into the seabed. The pulling force from the mooring chain 4 due to the movement of the ship is largely divided in the direction of the main anchor portion via the swinging link 25 and acts not only on the main anchor portion 1 and the auxiliary anchor portion 2 at the same time, but also on the main anchor. Even if the mooring angle of the mooring chain 4 with respect to the anchor is 45 ° to 60 °, the component force in the direction of the part causes the mooring force in the arrow direction from the main anchor part 1 to the auxiliary anchor part 2 along the shank member 3 so that the seabed is sandy Even when it is, a large mooring effect is exerted.

On the other hand, unfortunately, as shown in FIG.
If the claw blade 12 of the main anchor portion 1 bites into the reef R and is moored, the mooring chain 4 is pulled in the direction of the arrow A at the time of pulling up, so the pin engagement of the fitting member 23 is released and the mooring chain is released. 4 is separated from the auxiliary anchor portion 2 (see FIG. 3 (b)). The detached mooring chain 4 reaches the side of the main anchor portion 1 and is indicated by an arrow B.
Since it is pulled in the direction (see FIG. 3C), the claw blade 22 biting into the reef R is pulled in the direction opposite to the biting direction and is pulled up (see FIG. 3D).

Although the mooring chain 4 is used in the above embodiment, a mooring rope may be used, and it is easily deformed without departing from the scope of the present invention.
