Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a flexible anchor for ships, and in particular, when not in use, both the anchor arm and the anchor rod can be folded to make it compactly portable, and when in use, it can be carried easily on the seabed. This invention relates to a freely adjustable anchor whose anchor arm and anchor rod can be extended to easily escape even if there is trouble with an obstacle.

2. Description of the Related Art Generally, an anchor used by a small ship has one end connected to a chain or rope, and the other end of the handle protrudes from the other end at an acute angle. An anchor arm formed into a sharp point, and a rod-shaped anchor rod protruding from the other end of the anchor handle at approximately right angles to the anchor handle to give a predetermined angle to the anchor arm, or without the use of an anchor rod. It has an anchor arm in place of an anchor rod, and is anchored in the sea by input and pulled up from the seabed by input or engine power.

However, when anchoring on a reef or rocky area with many uneven seabeds, there are many cases where the anchor arm or anchor rod becomes stuck on an obstacle on the seabed and it becomes impossible to pull up. The problem was that they had to be abandoned on the ocean floor.

On the other hand, in order to deal with the above problem, an anchor specifically for use in areas where the sea floor has a complex uneven shape and has many roots, commonly known as ``fly'', has been considered.
For example, an anchor is used in which the anchor arm is made of soft iron, and when trouble occurs, the anchor arm can easily extend and escape by pulling strongly on the anchor rope. Such anchors have a shape in which the anchor arms are radially connected to the anchor handle, and have the disadvantage that they are limited to use in extremely narrow sea areas and can only be used on small vessels. In addition, in place of the above-mentioned anchor exclusively for "fly", there is also a flexible anchor devised by the present applicant (1983-
No. 147994) has been put into practical use, but when an obstacle hangs on it, the small net attached to the anchor arm breaks, and the anchor arm extends and becomes a rod, making it easy to escape from the obstacle. Even during transportation, the structure is such that if it is loaded onto a ship in the rod-shaped state, the storage space may be limited.

Problems to be Solved by the Invention Therefore, the present invention further improves the above-mentioned adjustable anchor, and has a new structure that allows the anchor arm and the anchor rod to more reliably extend and escape when an obstacle hangs. Furthermore, the main objective is to obtain a freely adjustable anchor in which both the anchor arm and the anchor rod can be not only extended but also folded in the shortening direction, that is, toward the anchor handle side, when carried.

Means for Solving the Problems In order to achieve the above-mentioned problems, the present invention provides an anchor handle consisting of a rod-shaped body having an end ring at one end to which a rope is connected and an anchor crown provided at the other end; A pedestal having an annular flange attached near the other end, and a bracket slidably fitted to the anchor handle between the pedestal and the anchor crown, and each having a pin hole, are arranged in four orthogonal directions. a guide ring formed protruding from the anchor, a ring slidably fitted to the anchor handle between the guide ring and the anchor crown, and a ring rotatably connected to a pair of opposing brackets of the guide ring by a pin. A main anchor arm, two anchor rods or anchor arms rotatably pin-coupled to a pair of opposing brackets on the other side of the guide ring, and a pin joint between the anchor arm and the anchor rod or anchor arm. a claw portion formed nearby and engaging the outer surface of the annular flange of the pedestal at different positions so as to project the anchor arm and the anchor rod or the anchor arm outward at a predetermined angle when anchoring; and a plurality of cotter pin insertion pin holes with different diameter lengths formed in the anchor handle located within the sliding range of the ring, and a cotter pin inserted into the cotter pin insertion pin holes. The present invention provides a freely adjustable anchor for a ship, characterized in that the anchor arm and the anchor rod or the anchor arm can be folded or extended substantially parallel to the anchor handle.

Effects According to the present invention, when the ship is sailing, the anchor arm and the anchor rod or the anchor arm can both be folded in the shortening direction to reduce the storage space, which can be a hindrance to workers in a ship where space is limited. It never becomes. When assembling the anchor when anchoring, if you open the anchor arm and the anchor rod or the anchor arm in order, the open position will be maintained by the action of the claws provided so that the engagement positions with respect to the flange are different. There is no need to open the anchor arm and the anchor rod or the anchor arm at the same time, and therefore one worker can perform the work alone. If a problem occurs such as the anchor arm or rod hanging on the seabed when pulling up after dropping the anchor,
When the anchor arm and the anchor rod or the cotter pin inserted through the small-diameter cotter pin insertion pin hole that restricts the rotation of the anchor arm are cut, both the anchor arm and the anchor rod elongate and become rod-shaped. Even if either the anchor arm and the anchor rod or the anchor arm are caught on an obstacle on the seabed, the anchor can easily escape.

Embodiment Hereinafter, an embodiment of the flexible anchor for ships according to the present invention will be described based on the drawings.

Fig. 1 shows the components of the freely adjustable anchor according to the present invention, the anchor arm, and the attached state of the anchor rod when anchoring (hypothetical diagram; the anchor rod is attached in a direction perpendicular to the anchor arm, but it is not shown in the figure). 1 is a rod-shaped anchor handle, which has an end ring 2 to which a chain or rope is connected at one end. An anchor crown 5 is provided at the other end. A pedestal 4 is formed near the other end of the anchor handle 1 and is integrally provided with an annular flange 3, and has a pin hole 6 for inserting a split pin and a second pin hole 6a. The pin hole 6 for inserting the cotter pin is a normal pin hole for regulating the rotation of the anchor arm and the anchor rod, and the second pin hole 6a prevents the anchor arm and the anchor rod from extending in the event of a cathedral. This is a pin hole used for securely locking to prevent Therefore, the second pin hole 6a is made to have a larger diameter than the split pin insertion pin 6 in order to use a pin that is not easily cut. Furthermore, the pin holes 6 for inserting the split pins have a plurality of holes radially drilled on the same plane with slightly different diameters so that the pin holes 6 are cut when an appropriate load is applied depending on the hardness of the split pin used. (not shown). A guide ring 7 is slidably fitted into the anchor handle 1 between the pedestal 4 and the anchor crown 5, and has one end in contact with the flange 3. Brackets 8a, 8b, 8c, and 8d in which pin holes 7a, 7b, 7c, and 7d are formed protrude from the guide ring 7 in four orthogonal directions. That is, as is clear from the plan view of the guide ring 7 shown in FIG. 2, pin holes 7a, 7b, 7c, and 7d are provided for the pair of two brackets 8a, 8b, 8c, and 8d. R is a ring which is slidably fitted onto the anchor handle 1 between the guide ring 7 and the anchor crown 5, and is positioned between the guide ring 7 and the anchor crown 5. This ring R is for selectively using the split pin insertion pin hole 6 and the second pin hole 6a, and this ring R is used as the guide ring 7.
When the ring R is brought into contact with the ring R, the split pin insertion pin hole 6 formed in the anchor handle 1 located within the sliding range of the ring R is hidden, and only the second pin hole 6a is exposed. Normally, the ring R is slid toward the anchor crown side to expose the pin hole 6 for inserting the split pin. Reference numerals 9a and 9b are anchor arms that are provided so as to protrude outward at an acute angle from the other end of the anchor handle 1, and have pin holes 10a and 10b on the base end side, respectively, and engage with the base 4. Claw portions 11a and 11b are provided in a protruding manner. The tip ends of the anchor arms 9a and 9b are sharply formed so as to bite into the seabed. Reference numerals 12a and 12b are anchor rods that are provided so as to protrude outward substantially at right angles to the anchor handle 1, and have pin holes 13a and 13b on the base end side, respectively, and a claw portion that engages with the base 4. 14a and 14b are provided in a protruding manner. These anchor rods 12a, 12b are anchor arms 9a, 9
b is provided with a predetermined angle, and the tip portion is formed into a rod shape. And anchor arms 9a, 9b
The claw portions 11a, 11b of the anchor rods 12a, 12b are set to have different engagement positions with the flange 3. Reference numeral 15 indicates pin holes 7a, 7b, etc. provided in the guide ring 7 and the anchor arm 9.
This is a pin that connects the anchor rods 12a, 12b and the anchor rods 12a, 12b.

FIG. 3 is an assembled view of the above components, in which a pin 15 is rotatably inserted into the pin holes 7a and 7b of the guide ring 7, and both ends of the pin 15 are locked with split pins (not shown). ), bracket 8a of guide ring 7,
Anchor arms 9a and 9b are rotatably connected to 8b. Similarly, the pins 1 are inserted into the pin holes 7c and 7d of the guide ring 7.
5 is rotatably inserted, both ends of the pin 15 are locked with split pins (not shown), and the anchor rods 12a and 12b are rotatably coupled to the brackets 8c and 8d of the guide ring 7. There is. At this time, the claw portions 11a and 11b of the anchor arms 9a and 9b are sandwiched between the guide ring 7 and the flange 3 of the pedestal 4, and the hollow portion 16 is sandwiched between them.
is formed. The assembled state in Figure 3 is the anchor arm 9.
a, 9b and anchor rods 12a, 12b are both anchor handle 1
It has a shape that is folded to the side, making it suitable for storage in a predetermined position on a ship during navigation. Next, we will explain how to use it when anchoring.
That is, when the ship reaches the destination sea area and assembles the anchor, first, as shown in FIG. 4, the anchor arms 9a,
When 9b is manually pulled obliquely downward, the tips of the claws 11a, 11b reach and engage approximately the middle position of the outer surface of the flange 3. At this time, the claw portions 14a and 14b of the anchor rod 12a are still sandwiched between the guide ring 7 and the flange 3, so the hollow portion 16 remains. Therefore, even if the operator takes his hands off the anchor arms 9a and 9b in this state, the anchor arms 9a and 9b are supported by the flange 3 and cannot be opened because the claws 11a and 11b are engaged with the flange 3. You can keep your feet on your feet.

Further, following the above operation, the anchor rods 12a, 1
The operation when the leg 2b is opened will be explained based on FIG. That is, from the state shown in FIG. 4, the anchor rod 12a,
When 12b is opened in the same way manually,
At the same time, the tips of the claws 14a, 14b on the anchor rods 12a, 12b side reach approximately the middle position of the outer surface of the flange 3, and at the same time, the claws 11a, 11b on the anchor arms 9a, 9b side
descends in the thickness direction of the flange 3, and the guide ring 7
The lower end of the flange 3 contacts the upper end of the flange 3 and the hollow portion 16 disappears. Then, slide the ring R toward the anchor crown 5 side to expose a plurality of small diameter cotter pin insertion pin holes 6 with different diameters radially drilled on the anchor handle 1 side, and select the optimal pin hole 6. The split pin 17 is inserted to complete the assembly. That is, the anchor arm 9
The claws 11a and 11b on the a and 9b sides and the anchor rod 12
Flange 3 of claw portions 14a, 14b on a, 12b side
Since the engagement positions are set to be different from each other, the assembly work as described above becomes possible. In addition,
The cotter pin 17 used in this case is one that will break when a strong load above a certain level is applied by the power of an engine or the like in the event of trouble when the anchor arm or the like is caught on the seabed. A plurality of holes with different diameters are drilled on the same plane so that appropriate diameters can be used depending on the hardness of the material. The split pin 17 is also made of iron, brass, or other material with appropriate hardness.
In short, it is sufficient that the split pin 17 is cut only when a trouble occurs and a load above a certain level is applied.

Next, we will explain what happens when a problem occurs, such as when the anchor arm or rod gets stuck on the seabed when pulling up the anchor. That is, in the assembled state shown in Fig. 5 (upside down from Fig. 5 when in use),
When a problem occurs, when the anchor handle 1 is strongly pulled from the seabed toward the sea surface, that is, when an attempt is made to pull up the anchor using power from an engine or the like, all the load is applied to the split pin 17, and the split pin 17 is broken. Then, the guide ring 7 will slide toward the anchor crown 5, and the anchor arms 9a, 9 will move.
b and the claw portions 11a, 11b of the anchor rods 12a, 12b.
Both 14a and 14b come off the outer surface of the flange 3 and become free, and by further pulling the anchor handle 1, the anchor arms 9a and 9 are removed as shown in FIG.
b. Both the anchor rods 12a and 12b are bent in the opposite direction of the anchor handle 1, that is, in the direction of extension, so that the entire anchor becomes rod-shaped, so that it is possible to easily escape from trouble. Note that since the upper end of the guide ring 7 serves as a cutting surface for cutting the pin 17, it is desirable to form it from a material with high hardness such as steel.

Furthermore, in cases where excessive loads are expected to be applied to the anchor arm etc. in the event of a break-up, etc., measures are taken to prevent the cotter pin 17 from being easily cut off, the anchor arm etc. being released, and the vessel being washed away. If it is necessary to securely attach an anchor arm or the like, a second pin hole 6a is used in place of the pin hole 6 for inserting a split pin. In other words, when assembling the ring R, the guide ring 7
to expose the second pin hole 6a, and a strong cotter pin 1 with high hardness is attached to the second pin hole 6a.
Insert 7. The second pin hole 6a has a larger diameter than the split pin insertion pin hole 6, and the split pin 17 used therein is also large and has high strength, so it cannot be subjected to a strong load above a certain level. A ship can be moored in a fixed position without being cut off. In other words, the second pin hole 6a is a pin hole for using a split pin that will not break even if a load above a certain level is applied, and the attachment strength of the anchor arm etc. can be changed depending on the purpose and place of use. can be made,
It can be used in optimal conditions.

In addition, in this embodiment, two anchor arms 9a, 9
b and two anchor rods 12a, 12b, but it is also possible to use an anchor arm instead of the anchor rods 12a, 12b and have four anchor arms. In this case, it will have four anchor arms, that is, four anchoring parts for the seabed, depending on the seabed in which it is used. In this way, it is possible to arbitrarily select whether to use an anchor rod, to use an anchor arm in place of the anchor rod, or to use four anchor arms. As mentioned above, the difference between an anchor arm and an anchor rod is the difference in the outward projecting angle and the shape of the tip.The anchor arm digs into the seabed and anchors the ship, while the anchor rod It has the function of raising the anchor arm at a predetermined angle in order to make it easier for the anchor arm to bite. In this case, the four anchor arms are attached at approximately the same angle, but each pair has a different contact position with respect to the flange 3 of the claw part, so that the assembly work can be performed independently. And how to use it when escaping trouble is the same as above. Further, since the anchor arm and the like are locked by the pin 15, assembly is extremely easy and simple, and it can be used in place of a normal anchor rod as appropriate.

Effects of the Invention As explained above, the free anchor according to the present invention includes an anchor handle made of a rod-shaped body having an end ring to which a rope is connected at one end and an anchor crown provided at the other end;
A pedestal having an annular flange attached near the other end of the anchor handle, and a bracket slidably fitted to the anchor handle between the pedestal and the anchor crown, each having a pin hole, are perpendicular to each other. A guide ring formed to protrude in four directions, a link slidably fitted to the anchor handle between the guide ring and the anchor crown, and a link rotatably connected to a pair of opposing brackets of the guide ring with a pin. two anchor arms, two anchor rods or anchor arms rotatably pin-coupled to a pair of opposing brackets on the other side of the guide ring, and a pin between the anchor arm and the anchor rod or anchor arm; A pawl formed near the connection and engaged with the outer surface of the annular flange of the pedestal at different positions so as to project the anchor arm and the anchor rod or the anchor arm outward at a predetermined angle when anchoring. a plurality of cotter pin insertion pin holes with different diameter lengths formed in the anchor handle located within the sliding range of the ring, and a cotter pin inserted into the cotter pin insertion pin holes. It is characterized in that the anchor arm and the anchor rod or the anchor arm can be folded or extended substantially parallel to the anchor handle, and has various advantages as described below. That is, since the anchor arm and the anchor rod or the anchor arm are both folded in the shortening direction in the state shown in FIG. 3 when the ship is sailing, the storage space is small.
It does not interfere with the workers inside the ship. Next, when assembling the anchor at the time of anchorage, if the anchor arm and the anchor rod or the anchor arm are opened in order, the opened state is achieved by the action of the claws provided so that the engagement positions with respect to the flange 3 are different. Since it is held, there is no need to open all four legs at the same time, and therefore, one worker can work alone. Furthermore, if a problem occurs in which the anchor arm or rod hangs on the seabed when pulling up after dropping the anchor, the split pin inserted through the small diameter pin hole will be cut, and the anchor arm or rod will be disconnected. Since the anchor rod or the anchor arm both extend and become rod-shaped, it is possible to easily escape even if either the anchor arm or the anchor rod gets caught on an obstacle on the seabed. Furthermore, when it is necessary to securely moor a ship in the event of a ship breaking, a second pin hole with a large diameter and a strong split pin are used to ensure that the ship will not break even under a certain load. The anchor arm can be
It can also be used in the shape it has, and the purpose of use,
It can be used in any condition depending on the place of use.

As described above, the present invention has various effects in use that conventional anchors do not have, and can be applied to a wider range of sea areas, and can be used not only for small vessels but also for other types of vessels. It has the advantage of being able to
