Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of an anchor used when mooring a ship in a harbor, shallow water, or lake, and more specifically, to a simple and easy-to-carry anchor structure mainly used as a main or auxiliary anchor for a small ship. .

[0002]

[Prior art]

 Anchor is an important connecting tool that sinks on the seabed or lakebed in order to anchor the ship at a predetermined position, and is widely used by general ships such as large ships as well as warships and small ships.

This anchor is of various shapes and sizes depending on the type and size of the ship, the main anchor or the secondary anchor, the purpose of use such as the size of the berthing period, the weather such as typhoons, etc. ing.

[0004] Here, the main anchor is an anchor that is mainly pulled down from the bow to the seabed or lakebed and exerts the strongest function of the anchor, and when one anchor is used for anchoring (single anchor). The anchor is the main anchor, and if two anchors are used for anchoring (double anchors), both anchors will be the main anchor if they have similar functions.

In addition, the secondary anchor is a case where a large number of boats exist near the anchorage and a large anchor berth (the range in which the boat moves due to wind or tidal current) cannot be taken, or when it is desired to set the fishing place to a fixed position as much as possible. Anchor used as an auxiliary to the ship, which is mainly lowered from the stern to the seabed or lakebed.

As these anchors, for example, a common type anchor as shown in FIG. 5 (a) is used as a main anchor of a small vessel or a secondary anchor of an escort vessel, and the vessel is washed away by a strong wind such as a typhoon. An admiralty-type anchor as shown in FIG. 5 (b), which is suitable for preventing spillage, is used as a main anchor for British ships and new escorts.

[0007] In addition, these anchors are used for large ships such as warships, ferry boats, and large fishing boats, where the deck is equipped with a lifting anchor device that winds the anchor chain connected to the main anchor and a storage box that stores the wound anchor chain. It has been installed and is always in the hull.

Further, in a small boat such as a fishing boat or a small fishing boat, an anchor and a rope or the like connected to the anchor are placed in a predetermined hangar inside the boat or a corner near the bow.

[0009]

[Problems to be solved by the device]

 However, the above-mentioned conventional anchor has various problems as described below.

That is, since the anchor is integrally molded or has a structure that is extremely difficult to disassemble once assembled, it may be aboard a large ship, etc., where the deck is equipped with an anchorage device or an anchorage. For small vessels with a small area, the anchors are bulky and take up space, and the space inside the ship is even narrower.In addition, it is not easy to carry the anchors on ships that do not have anchors. There was a problem.

For this reason, small boats such as one-seater or two-seater boats often do not have anchors, and even if you want to enjoy fishing at a fixed position in a shallow sea or lake, the hull will be hulled by wind or tidal current. There was a problem that it would be washed away.

When a large number of small boats are crowded in a bay or a lake at a fishing competition or the like, the above problem is remarkable, and it is not uncommon for the boats to collide with each other.

[0013] Also, small boats are greatly affected by the waves and oscillate significantly. However, when such a small boat berths by anchoring a conventional anchor, it will be further oscillated, resulting in sea sickness. There was a problem that the ship was likely to capsize.

Further, reflecting the recent fishing boom, the number of anglers who own boats has increased dramatically, but when these anglers go out to fishing places such as the sea and lakes, they carry a conventional integrally molded anchor. It is not easy to do because the anchors are bulky and take up space as in the case of carrying it onboard, and there is a problem that the anchors tend not to be carried.

Further, even in a large-sized or medium-sized ship that is always equipped with anchors, if a secondary anchor is used in addition to the main anchor to reduce the anchor berth, a temporary auxiliary anchor is used in addition to the permanent anchor. In some cases, it was expected that a simple and easy-to-store anchor would appear.

The present invention has been made in view of the above circumstances, and provides a simple and easy-to-carry anchor structure that can be easily used as a main anchor for small boats or as a secondary anchor for large and medium-sized ships. Is.

[0017]

[Means for Solving the Problems]

 The present invention is directed to an anchor portion provided with a protruding portion having a pointed portion and a screw hole configured to dig into the seabed or a lake bottom, a connecting rod connected to an anchor chain or an anchor rope, and the protruding portion of the protruding portion. The stock rod having a screw thread formed at one end portion to be screwed with the screw hole, the projecting portion and the connecting rod are fitted into each other, and a through hole through which the stock rod passes is provided to provide the projecting portion. An anchor structure comprising: an outer fitting cylinder configured to be connected to the outer fitting cylinder; and a coil spring that urges the outer fitting cylinder in a direction in which the protruding portion and the connecting rod are in contact with each other. By solving the above problems, the above problems are solved.

[0018]

[Action]

 In the anchor structure according to the present invention, the tip provided on the anchor part digs into the seabed or the lake bottom to generate a force to hold the hull (so-called holding force).

By screwing the screw hole of the protruding portion provided in the anchor portion and the screw thread of the stock rod that penetrates the through hole of the outer fitting cylinder, the protruding portion, that is, the anchor portion and the outer fitting cylinder. And are connected.

The connecting rod and the projecting portion face each other in the outer fitting cylinder, and the anchor portion and the connecting rod are coupled by being biased by the coil spring in a direction in which they are in contact with each other.

As a result, the anchor portion, the outer fitting cylinder, and the connecting rod are integrated, and one anchor is assembled.

【Example】

 Hereinafter, embodiments of an anchor structure according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of an anchor structure according to the present invention, FIG. 2 is a front view showing the same embodiment, and FIG. 3 is a sectional view taken along line AA in FIG. 2 showing the same embodiment. 4 is a sectional view corresponding to FIG. 3 showing expansion and contraction of the coil spring of the embodiment, FIG. 5A is a perspective view showing a conventional common type anchor, and FIG. 5B is a conventional admiralty type. FIG. 6 is a perspective view showing the anchor of FIG.

The main part of the anchor structure according to the present invention is an anchor part 14 provided with a pointed part 10 and 11 configured to bite into the sea bottom or a lake bottom and a protruding part 12 having screw holes 13 and 13a. , A connecting rod 16 connected to an anchor chain or an anchor rope 15 and stock rods 18 and 18a having screw threads 17 and 17a screwed into the screw holes 13 and 13a of the projecting portion 12 at one end. And an external fitting configured such that the projecting portion 12 and the connecting rod 16 are fitted to each other and a through hole 19 through which the stock rod 18 penetrates is provided to be coupled to the projecting portion 12. A cylinder 20 and a coil spring 21 for urging the protruding portion 12 and the connecting rod 16 in the direction of contacting the protruding portion 12 and the connecting rod 16 are provided in the outer fitting cylinder 20.

In this embodiment, an anchor structure is formed as shown in FIGS. 1 to 4, and this structure will be described in detail below.

First, the anchor portion 14 is made of stainless steel, and the pointed portions 10 and 11 that bite into the seabed or the lakebed are the so-called anchor heads 30 of the conventional anchor shown in FIGS. 5A and 5B. , 31 has a sharp tip and has a shape with an acute angle so that it can pierce an object (sea floor, lake bottom, etc.), and its tip portions 10, 11 are located at the central portion of the anchor portion 14. The shape is curved as it is separated from the provided protruding portion 12.

The protruding portion 12 has a columnar shape, is formed by integrally molding with the pointed portions 10 and 11, and has screw holes 13 and 13a screwed into two opposite positions on the circumferential curved surface thereof. Is.

The protruding portion 12 does not have to be integrally formed with the tip portions 10 and 11, but can be detachable with a screw so that the anchor can be further disassembled. Be prepared for.

The connecting rod 16 is made of stainless steel, and is provided with a cylindrical central portion, a ring portion 24 for connecting the anchor chain or the anchor rope 15 at one end, and a screw hole 25 at the other end. The hexagonal bolt 22 is screwed into the threaded screw hole 25 through a circular nut 23 having the same outer peripheral length as the circular end surface 12 a of the protruding portion 12.

The coil spring 21 is a compression spring made of stainless steel spring rope, and the circumference of the coil spring 21 is sized to be wound around the central portion of the connecting rod 16, and the circular nut 23 and the external fitting cylinder described later. The coil spring 21 is configured to be inserted between the bent corner portion 27 and the bent corner portion 27 of the coil 20, and to contact the end surface 23a of the circular nut 23 and the bent corner portion 27.

Since a large force is applied to the coil spring 21 during use of the anchor, there is a high risk that the coil spring 21 will be damaged if rust is generated by seawater, but in order to avoid this and increase the service life, As described above, it is desirable to use the coil spring 21 made of stainless steel that does not cause rust as described above.

The outer fitting cylinder 20 is made of stainless steel, and one end thereof has an opening having a size into which the protruding portion 12 is inserted, and the other end has a hole 26 having a size into which the central portion of the connecting rod 16 is fitted. The opening has a bent corner portion 27.

Further, through holes 19 and 19 through which the stock rods 18 and 18 a can respectively pass are provided at two opposing positions on the circumferential curved surface of the outer fitting cylinder 20.

The stock rods 18 and 18a are made of stainless steel, and at one end thereof, screw threads 17 and 17a to be screwed into the screw holes 13 and 13a of the projecting portion 12 are formed, and at the other end, hexagonal. It has the same shape as the head of the bolt.

Further, hexagon nuts 28, 28 a screwed to the screw threads 17, 17 a are attached to the stock rods 18, 18 a to ensure the connection between the protruding portion 12 and the outer fitting cylinder 20.

If the hexagon nuts 28, 28a and the head of the hexagon bolt 22 are made to have the same size, the anchor can be assembled and the coil spring 21 can be replaced with one tool, and the number of portable tools can be reduced. Therefore, it is desirable that both have the same size.

The stock rods 18 and 18a correspond to the stock in the stock anchor, which is a conventional anchor classification, and correspond to the stock 32 in the common anchor shown in FIG. 5 (a).

Incidentally, the admiralty-type anchor shown in FIG. 5B belongs to the class of stockless anchors.

Next, with regard to the usage method and usage status of the anchor structure configured as described above, an example is given of a case where a person goes by car to a shore or a lake and rides on a small boat for one person or several people. To explain.

First, in the anchor of this embodiment, as shown in FIG. 1, the connecting rod 16, the coil spring 21, the circular nut 23, the hexagon bolt 22 and the outer fitting cylinder 19 are assembled so that they do not come apart. , The anchor portion 14 and the hexagon bolt stock rods 18 and 18a, that is, disassembled into four portions.

After that, these disassembled parts and the anchor rope are packed in a bag or tied with a string to prevent the disassembled parts from being separated, and the disassembled parts are loaded in a car trunk or the like.

At this time, since the disassembled parts are compactly assembled, it does not become bulky in the trunk, there is no difficulty in locating them, and they can be stored in the trunk at all times. It is convenient for carrying an anchor.

When the boat arrives at the target beach or lake, the anchor is carried along with fishing tackles in a small boat, but since the anchor is compactly packed, it is easy to carry onboard.

Therefore, even in a small boat that does not always have anchors, the anchors can be easily loaded and the anchors are not bulky, so that the inside of the boat does not become narrow.

After loading the anchor, head to the target fishing area with a small boat and stop the engine etc. at a predetermined position to stop the progress.

When it is desired to anchor at that position, the anchor is lowered. At this time, the disassembled parts are assembled as described below.

That is, as shown in FIG. 1, the hexagon bolt 22 at the end of the connecting rod 16 is placed on the circular end surface 12 a of the projecting portion 12, and the outer fitting cylinder is lowered to the projecting portion 12. Extrapolate.

At this time, as shown in FIG. 3, the through holes 19 and 19a are respectively adapted to the screw holes 13 and 13a of the projecting portion 12, and the threaded portions 17 and 17a of the respective stock rods 18 and 18a are connected. The anchor assembly is completed by screwing into the screw holes 13 and 13a and tightening the hexagon nuts 28 and 28a to the outer fitting cylinder 20.

Anchor rope 15 having a length adapted to the sea depth or the lake depth is tied to the loop portion 24 of the anchor, and the other end of the anchor rope 15 is connected to a mooring member on the bow of the small boat, Lower the anchor to the sea or lake bottom.

As a result, it is prevented that the tip portions 10 and 11 of the anchor bite into the bottom of the sea or the lake, and the hull is washed away by wind or tidal current due to the holding force.

When the hull sways due to waves or wind, as shown in FIG. 4, the connecting rod 16 is pulled through the anchor rope 15 in the swaying direction of the hull, and as a result, the projecting portion 12 is pulled. Although the contact between the circular end face 12a and the hexagonal bolt 22 is temporarily released, since the restoring force of the coil spring 21 is constantly working, the swinging degree of the hull can be reduced.

In particular, in a small boat that is easily affected by waves and swings easily, the effect is great and the occurrence of seasickness and capsizing of the hull is prevented.

When waves and winds are strong and the hull is strongly shaken, the coil spring 21 can be easily attached and detached by screwing the screw hole 25, the hexagon bolt 22 and the circular nut 23. If the coil spring 21 is damaged, it can be replaced immediately, and by replacing the coil spring 21 with a coil spring having a smaller elastic coefficient, it is possible to adjust the swinging degree of the hull to be small.

For this reason, it is desirable that the coil springs 21 carry a plurality of coil springs 21 of the same kind or a plurality of coil springs 21 having different elastic coefficients and board the ship.

By using the anchors in this way, it is possible to prevent the boats from colliding with each other when many small boats are crowded in the bay or lake at a fishing competition or the like. In addition, if you want to make the anchor berth smaller, you can use multiple anchors as another main anchor or secondary anchor.

Next, when the fishing is completed and the fish is returned to the shore or lake shore, the anchor rope is pulled to raise the anchor, disassembled in the reverse order of the above-mentioned assembly, and compacted as before loading. Place it in a corner of the ship and return to it.

As described above, the case of fishing on a small boat has been described as an example. However, even for a large or medium-sized ship which is always equipped with an anchor, it is suitable for the size of the hull and the required holding power. The anchor berth can be made even smaller by using anchors of the size and shape as temporary anchors in addition to permanent anchors.

Although the present invention has been described based on the embodiments, the present invention is not limited to these.

For example, the anchor parts of the above-mentioned embodiment are all made of stainless steel, but the invention is not limited to stainless steel, and the metal or the like used for conventional anchors can be used. .

Further, the coil spring for urging the projecting portion and the connecting rod in the direction of contacting each other is not limited to the above-mentioned structure, and the tensile coil spring is embedded in the hole formed at the one end of the connecting rod. Alternatively, the connecting rod and the protruding portion may be connected by.

[0061]

[Effect of device]

 Since the anchor structure according to the present invention is configured as described above, it has the following effects.

(1) Since it is an assembly type anchor and the anchor is not bulky at the time of disassembly, the storage volume is small, and the interior of a small ship with a small inboard area does not become narrower. In addition, it has an excellent effect that it is easy to carry the anchor in a ship even if the ship does not always have the anchor.

(2) When the hull oscillates due to waves or wind, the restoring force of the coil spring always works, so the degree of swaying of the hull can be reduced, and the occurrence of sea sickness and capsizing can be prevented. It has an excellent effect of being able to do.

(3) In particular, the above effect is remarkable in a small boat that is easily affected by waves and is likely to sway, and even when many small boats are crowded in a bay or lake, It has an excellent effect that it can prevent mutual collision.

(4) Large or medium-sized ships with anchorages can be easily used as temporary auxiliary anchors because they are simple and easy to store, and small ships are easy to carry and bulky. Since it does not exist, it has an excellent effect of preventing non-carrying of the anchor.
