Abstract

PURPOSE:To provide a single claw anchor which is linearly advanced and seated in the direction of a target and facilitates anchoring operation by mounting auxiliary wings in juxtaposition with each other on the end parts on both sides of a main wing body bent laterally symmetrically about a central part to which a shank mounting plate is attached, and mounting the shank, to which a weight is attached, on the shank mounting plate. CONSTITUTION:A shank mounting plate 5 is mounted on the central part of a main wing body 1 bent laterally symmetrically about a central part at a proper angle of elevation, a shank 7 is attached to the shank mounting plate 5, and a weight 7a is attached to the tip of the shank 7. Auxiliary wings 3 are mounted in juxtaposition with each other on the end parts on both sides of the main wing body 1 at a proper angle of elevation, and a self-running direction is stabilized through prevention of zigzagging of a self-running anchor. Thus, when, after the anchor is seated, an anchor rope is properly pulled, a claw 2 at the rear end part of the main wing body 1 is seated through soil on a seat bottom and secured with a proper anchoring force. This constitution predicts the seating place of the anchor and extremely simplifies driving of a plurality of anchors reduced in whirling.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention enables the anchor to be anchored without being affected by the current.
This relates to a single-claw anchor that can travel straight and land in the desired direction, and facilitates anchoring operations.

[Prior Art] Conventionally, as anchors used for anchoring small ships, yachts, etc., navy type or dungeon type anchors, whose shank can freely rotate within a certain angle, have been widely used.
These anchors have relatively weak holding power, and because simple anchoring methods such as single anchoring, which will be described later, are often adopted, they are required compared to the weight of the vessel to securely anchor. There was a tendency for heavier and larger ones to be used.

[The fi that the invention tries to solve! ! ] Common anchoring methods include single anchoring and double anchoring.

The former is a method of mooring by setting an anchor, and although it has the advantage of being easy to work with, it only blocks the anchored ship's mark in one direction.
The disadvantage is that it tends to swing around due to the wind. In order to suppress this whirling, the latter method is adopted, and this is a method in which two anchors are driven a certain distance apart from both sides of the ship, which reduces whirling. Similarly, there is a method of driving two anchors, one in the bow and one in the stern direction, and in order to further suppress whirling, three anchors are placed at 120° intervals around the anchored vessel. A method of driving in the direction has also been adopted.

In the above-mentioned anchoring methods, except for single anchoring, driving in multiple anchors is difficult for workers who are not able to act as boat lights. In other words, when most conventional anchors are dropped, their weight causes them to sink toward the seabed directly below the anchor point, but if the anchor lobe is retracted appropriately, the anchor's claws dig into the soil on the seabed, making it difficult to hold the anchor. The anchor was fixed with force, and while pulling out the anchor lobe into the sea as appropriate, the vessel was moved to another anchor driving point, and after anchoring 's2 anchor, it returned to the midpoint between the anchoring points of both anchors and It is necessary to fix the two anchor lobes tightly attached to the anchor to the ship's hull with a certain amount of tension, and each anchor must be anchored and dug into the seabed, and the ship must be moved to anchor. However, this requires skill, time and effort, and is troublesome.

The present invention eliminates the drawbacks of the above-mentioned prior art,
The anchor is moved straight through the water at a certain angle in a certain direction, making it possible to predict where the anchor will land on the bottom.This allows each anchor to be driven in without moving the hull when driving multiple anchors. This provides a single-claw anchor that is devised so that it is extremely easy to drive a plurality of anchors with little swinging around.

[Means for Solving the Problems] To summarize the present invention, the invention according to claim 1 relates to a single-claw anchor that, when immersed in the sea, moves straight in the direction of travel while maintaining a constant inclination angle. It has the characteristic of self-propelling underwater, and by pulling the anchor lobe after landing on the bottom, the claws dig into the sediment on the seabed.The structure is such that a shank mounting plate (5) is provided in the center, and Ailerons (3) are connected to the left and right ends of the main wing body (1), which is symmetrically bent with an appropriate elevation angle, and have an appropriate depression angle, and a weight (7
The shank (7) provided with a) is attached to the shank mounting plate (5) at the appropriate position.

Furthermore, the invention as set forth in claim 2 relates to an improvement of the single-claw anchor as set forth in claim 1, and has a function of adjusting the opening angle between the main wing body and the shank, and the configuration thereof is the same as that in the above-mentioned claim. In the main wing body (1) and shank (7) described in 1, a shank attachment plate (5
) is set upright, and the shank (7) is installed between the shank mounting plates (5).
) is installed at the appropriate location, and a through-hole plate (6) with a long hole (6a) is connected to the rear side of the shank mounting plate (5), and is inserted into the end of the slide plate (8). The bolts, etc.
) into the long holes (6a) and tighten bolts as appropriate to make the slide plate (8) movable within the width of the long holes (6a) of the through-hole plate (6), and then attach the other end of the slide plate (8). The fixing hole (10) of the shank (7) is rotatably attached to the lower part of the shank fixing plate (10), and the fixing hole (10
b), a plurality of angle adjustment holes (7e) are bored in appropriate positions of the shank (7), the shank (7) is positioned between the shank fixing plates (10), and the fixing holes (10b) and The shank (7) and the shank fixing plate (10) are fixed together by inserting a bolt or the like between the angle adjustment holes (7e) and tightening the bolt.

In addition, the invention according to claim 3 is similar to the above, as described in claim 1.
This invention relates to an improvement of the single claw anchor according to claim 1, and its configuration is such that, in the main wing body (1) and the shank (7) according to claim 1, the shank is attached to the tip of the central part of the main wing body (1). A plate (5) is erected, a shaft provided at an appropriate position of the shank (7) is mounted between the shank attachment plates (5), and the shaft is connected to an appropriate position of the shank attachment plate (5) or the main wing body (1). The shank fixing plate (1) holds the shank (7) at a constant opening angle.
0) and the shank (7), there is a weak part (13a) in a part formed by cutting appropriate places of bolts, screws, rivets, etc.
A superposition fixing member (13) having a structure is inserted through the superposition fixing member (13), and the two members are fixed in an overlapping state.

[Operation] The present invention has the above-mentioned configuration. First, in the invention according to claim 1, the central portion of the main wing body (1) is bent symmetrically from the central portion at an appropriate angle of elevation. A shank mounting plate (5) is provided at the appropriate location, the shank (7) is mounted at the appropriate location on the shank mounting plate (5), and a weight (7a) is provided at the tip of the shank (7). The center of gravity of the anchor is located toward the tip of the solid axis of the main wing body (1), and when it is immersed in water, the symmetrical main wing body (1) bent from the center with an appropriate elevation angle will exert lift. As a result, the robot can propel itself underwater at an inclination angle that balances the lift force and the gravity acting on the center of gravity.

Additionally, ailerons (3) are connected to the left and right ends of the main wing body (1) with appropriate depression angles, and the ailerons (3) perform a function similar to the vertical tail of an aircraft and are self-propelled. This prevents the anchor from meandering, stabilizes the self-propelled direction, and allows it to travel straight without being affected by tidal currents.

After the anchor has landed on the bottom, when the anchor lobe is pulled appropriately, the claw (2) at the rear end of the main wing body (1) bites into the earth and sand on the seabed and is fixed with an appropriate holding force.

Further, in the invention according to claim 2, the shank (7
) is not open and is not fixed by the shank fixing plate (10), the slide plate (8) is attached to the through-hole plate (
Since it is movable back and forth within the width of the elongated hole (6a) in 6), the shank fixing plate (10) rotatably attached to the end of the slide plate (8) is also movable back and forth within the width of the elongated hole (6a). 8
) can be moved in the forward and backward directions, and the shank fixing plate (10
), by drilling a plurality of angle adjustment holes (7e) at appropriate intervals in the shank (7) interposed between the shank fixing plates (10), the shank fixing plate (10) moves.
0) and any of the plurality of angle adjustment holes (7e) by moving the slide plate (8) back and forth, and insert bolts, etc. into each matching hole. Insert the shank fixing plate (10
) and the shank (7) are polymerized and fixed, then the shank (7)
) is lifted upward, the slide plate (8) that is pivoted to the lower end of the shank fixing plate (10) is also lifted, and the bolts inserted through the end of the slide plate (8) are inserted into the through holes. The shank (7) opens to a certain limited angle by engaging with the edge of the long hole (6a) of the plate (6) (edge on the rear end side of the main wing body) and preventing movement. The opening angle of the shank (7) is determined by the number of holes provided on the shank (7) that are fixed between the shank fixing plates (10) by inserting bolts, etc. together with the fixing holes (IOB) of the shank fixing plate (10). The opening angle of the shank (7) can be changed depending on the selection of the angle adjustment hole (7e).
It becomes adjustable by selecting e). That is, when the shank (7) is fixed to the shank fixing plate (10) using the angle adjustment hole (7e) located at the tip side of the shank (7) provided with the weight (7a), the maximum opening Shank (7) that forms an angle and, conversely, encircles the anchor ring.
When the shank (7) is fixed to the shank fixing plate (10) using the angle adjustment hole (7e) located on the rear end side, the opening angle is the maximum φ, and the shank (7) ) allows fine adjustment of the opening angle.

In addition, in the invention according to claim 3, a weakened portion (13a
), the claws (2) of the main wing body (1) dig into the seabed and are fixed, allowing the hull to move toward the bottom of the anchor and attaching the anchor lobe to the shank (7). ) of the polymerization fixing member (13) by applying a rotational force in the direction of opening of the shank (7).
a) breaks and the shaft (7) rotates beyond the maximum opening angle, and by pulling the anchor lobe appropriately, the main wing body (1) that has dug into the seabed can be easily removed. As a result, it is possible to prevent entanglement.

(8) is a slide plate, one end of which is inserted into a leg part such as a bolt (9a) from the inside, and the leg part is inserted into each through-hole plate (6
) into the elongated hole (6a) from the inside of the nut (
9b) etc., so that the slide plate (8) can be moved back and forth with respect to the perforated plate (6) and can be rotated within a certain angle.

(10) is a shank fixing plate having a U-shaped cross section, and has an insertion hole (10a) in the lower part, and a leg of a bolt (11a) inserted into the other end of the slide plate (8) from the inside. The slide plate (8) and the shank fixing plate (10) are rotatably connected by inserting the part through the shank and loosely tightening the bolt with a nut (11b) or the like. Three fixing holes (10b) are bored at appropriate intervals in the upper part of the shank fixing plate (10).

In this embodiment, in order to fix the shank (7) between the respective shank fixing plates (10), bolts, etc. are used at three locations, and the fixing holes (
tab) are provided at three locations at the same spacing as the multiple angle adjustment holes (7e) described later, but when bolting, etc. is performed at only one location, the fixing hole (10b) is also provided at only one location. This is the result.

The branch part (7b) of the shank (7) is interposed between each shank mounting plate (5), and the insertion hole (7C) of the shank (7) and the shaft hole (5a) of the shank mounting plate (5) are matched. Then, insert a bolt (12a) or the like between the two members through either one of the shaft holes (5a), and tighten the bolt with a nut (12b) or the like, so that the shank (7) can freely rotate within a predetermined range. The shaft is mounted on the shaft. At this time, the bolt (12a) becomes a shaft provided at a proper position on the shank (7).

When the shank (7) is attached to the shank mounting plate (5), the shank (7) is attached between each shank fixing plate (10).
), the slide plate (8) is connected to the perforated plate (6).
) When moving back and forth within the width of the elongated hole (6a), each shank fixing plate (10) slides into the branch (7b) of the shank (7) within the range of the branch (7b). In this embodiment, a plurality of angle adjustment holes (7e) are bored at appropriate intervals in four locations.

(13) is a superimposed fixing member such as a bolt, nut, bottle, etc. As shown in Fig. 8, the shank (7) is interposed between each shank fixing plate (10) and superimposed, and one of the shank fixing plates is superimposed. Insert it through the fixing hole (10b) of the plate (10),
When tightening with a nut etc. from the opposite side, the shank (7)
A weak portion (13a) is formed by cutting or the like at a portion to be inserted into the angle adjustment hole (7e). In this embodiment, the weakened portions (13a) are provided around three central locations of the bolt (13) (the locations that contact the left and right opening edges of the angle adjustment hole (7e) of the shank (7)). The weak part (13a
) may be provided around the bolt (13) or the like at an appropriate location.

Next, to explain the state of use, the shank fixing plate (10
) while moving back and forth, the positioning hole (iob) and any angle adjustment hole (7e) of the shank (7) are matched, and the overlapping fixing member (13) is inserted and overlapping is fixed. In this case, in the angle adjustment hole (7e) of the shank (7), the weight (7a
), the angle of the shank (7) will be maximum. (about 3 times is required), select the angle adjustment hole (7e) where the opening angle of the shank (7) is large. In the case of this example, the maximum opening angle of the shank (7) is set to 40°, and the angle adjustment holes (7e) are arranged at the same intervals in the four housings so that the opening angle is 35° and 25° sequentially. did.

Next, when the shank (7) is closed and immersed in water with the shank (7) facing in any direction, the anchor will move straight in a certain direction while balancing at a certain angle of inclination (a in Figure 9). After landing on the bottom, when the anchor rope is pulled appropriately, the shaft (7) opens at a predetermined angle, and the claw (2) connected to the rear end of the main wing body (1) bites into the sand and sand on the seabed. When you pull the anchor rope, the shaft (
The tensile force applied to the tip of 7) is converted into a force that moves the main wing body (1) backward through the shaft attachment part, and the main wing body (1) digs into the sand up to the middle, causing the main constituent material to Since more than half of the main wing body (1) digs into the earth and sand, the anchor is fixed to the seabed with a strong holding force (Figure 9, middle entrance).

Next, when anchoring, the hull is moved in the direction of the anchor bottoming, and the shank (7) to which the anchor rope is tightly attached is applied a rotational force in the direction of opening of the shank (7), whereby the polymerization is fixed. When each of the weakened parts (13a) of the member (13) breaks and the shaft rotates beyond the maximum opening angle and rotates to the direction in which the single-claw anchor bites, the anchor rope can be stretched as appropriate. This will allow you to easily remove the stuck single-jaw anchor (see Figure 9).

[Effects of invention According to the present invention having the above configuration, the following effects are achieved.

In the invention as claimed in claim 1, since the anchor can be moved straight through the water in a certain direction at a certain angle of inclination, it is possible to predict the place where the anchor will land on the bottom. This makes it possible to drive each anchor without moving the anchor, making it extremely easy to drive multiple anchors with little swinging around. Because it bites in, the anchor can be fixed to the seabed with strong holding power, and the main wing body (1) also functions as a body that bites into the sediment on the seabed.
There is no need to provide a separate biting body, and the weight can be reduced accordingly, making it possible to provide a compact and lightweight single-claw anchor.

Further, in the invention according to claim 2, the shank (7
) can be reliably adjusted with a simple configuration, and the optimal opening angle can be selected depending on the depth and length of the anchor rope. Even when the length (depth 1: anchor rope 3) is insufficient, the main wing body (1) can be reliably dug into the earth and sand from the anchor claw (2) after landing on the bottom.

Moreover, in the invention according to claim 3, by forming a weakened part (13a) in a part of the polymerization fixing member (13),
Simply moving the hull in the direction of the anchor landing on the bottom prevents the anchor from becoming entangled, making it extremely easy to remove an anchor that has become entangled in a rock on the seabed, without having to take the time to use a ladle. It becomes possible to make a ladle.

As described above, according to the present invention, it is possible to provide a single claw anchor that can be easily operated even by a person who is not skilled in handling anchors.
