Description

[Detailed description of the device]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an anchor used when mooring a hull or a floating body on water, and more particularly to an anchor that is effective for mooring in a sandy mud bottom area.

[0002]

[Prior art]

 Conventionally, an anchor has an anchor claw (d) at the end of an anchor arm (c) extending on both sides of an anchor crown (b) formed at the tip of the anchor trunk (a) as shown in FIGS. 6 to 8. A Japanese anchor in which an anchor (e) that is formed and directly intersects with the anchor (ha) is provided on the anchor crown (b), and an anchor (or) orthogonal to the anchor (ha) as shown in FIGS. 9 to 11. (E) Western anchor provided on the anchor trunk (a), as shown in FIG. 12 to FIG. 14, a pivotable anchor claw axis (f) which is orthogonal to the tip of the anchor trunk (a) and protrudes on both sides. An anchor claw seat plate (CH) having a window hole (G) in the center is fixed to both sides of the anchor claw shaft (F) on both sides of the vertical center part of the anchor claw seat plate (CH). Moreover, the warship anchor in which the anchor claw (i) orthogonal to the anchor claw seat (h) is fixed to the anchor claw seat (h), is orthogonal to the tip of the anchor trunk (a) as shown in FIGS. 15 to 17. -Shaped and protruding on both sides to rotate independently The provided, there is a Danforth anchor or the like fixed to the two respective tips are Aiyo' in triangular Ikaritsume (j) at both ends of the Ikaritsumejiku (f).

The Japanese anchor and the Western anchor have almost the same shape and the same performance, the anchor trunk (a) has a square or round cross section, has a large ground contact area, and does not infiltrate into the sand at the bottom of the water. Since only one anchor claw (d) bites into the soil on the bottom of the water, its holding power is relatively small. The warship anchor has a square cross section to hold weight, and has a large ground contact area so that it does not sneak into the sediment on the bottom of the water. Due to the resistance of the earth and sand, a force is exerted in the direction that lifts the anchor claw (ri), so the holding power is rather small. Danforce anchor has two anchor claws (nu) and has a triangular shape, and although it is easy to bite into the sediment at the bottom of the water, since the tips of the anchor claws (nu) collide, When the soil layer is hard, or when algae grows on the bottom of the water, the anchor claws (nu) are difficult to bite, roll over easily, and there is a problem that they cannot be held securely.

In view of such circumstances, the present inventor has two anchor claws (L) having a large surface area as shown in FIGS. An anchor that has a retaining frame (wo) and an anchor trunk (a) with a wide and thin wall, which makes it easy to sneak into the sand on the bottom of the water, has been previously disclosed (JP-A-60-110591).

[0005]

[Problems to be solved by the device]

 There is a problem of how to secure the anchoring disclosed in Japanese Patent Laid-Open No. 60-110591 and to further secure the retaining power.

[0006]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems, and has a thin and wide anchor trunk, and a pivotal anchor claw shaft protruding orthogonally and on both sides is provided at the tip of the anchor trunk. The bases of the thin and plate-shaped anchor claws are fixed to both end portions of the anchor claw shaft, and the thin and annular anchor claw stop frames are provided vertically facing each other in a direction orthogonal to the extending direction of the anchor claw. Both ends of the anchor are fixed to the anchor claw shaft corresponding to the base of the anchor claw, and project from the end of the anchor claw stop frame on the side of the center part and vertically face the anchor claw in parallel with the extension direction of the anchor claw to support the auxiliary claw. It provides an anchor characterized by being formed.

[0007]

[Action]

 In the anchored state of the present invention, the tip of the anchor claw slightly digs into the water bottom in the landing state, and the tip of the auxiliary claw also slightly digs into the water bottom. And the auxiliary claws not only go deeper into the sediment of the water floor, but also the anchor frame and the anchor trunk penetrate into the sediment of the water bottom, and then the anchor becomes fixed.

[0008]

[Embodiment of the invention]

 Embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, an anchor 1 of the present invention has a thin and wide anchor 2 having a substantially rectangular cross section. Boss portions 2a, 2a are formed on both sides of the tip of the anchor trunk 2, and an anchor claw shaft insertion hole 3 is formed through the boss portions 2a, 2a. On the other hand, boss portions 2b, 2b are formed on both sides of the rear end portion of the anchor trunk 2, and an anchor rope mounting hole 4 is formed through the boss portions 2b, 2b. Through the anchor claw shaft insertion hole 3, a central portion of a rotatable anchor claw shaft 5 which is orthogonal to the anchor trunk 2 and protrudes on both sides is inserted. The bases 6a and 6a of the anchor claws 6 and 6 are fixed to both ends of the anchor claw shaft 5, and the pointed portions 6b and 6b of the anchor claws 6 and 6 have a shape in which the width gradually decreases. . Further, the anchor claws 6, 6 have a flared shape toward the tip portions 6b, 6b. The both ends 7a, 7a of the thin-walled ring-shaped or square ring-shaped anchor claw stop 7, 7 are fixed to the anchor claw shaft 5 and the bases 6a, 6a of the anchor claw 6, 6, and the anchor claw stop frame Reference numerals 7 and 7 are set so as to be orthogonal to the extending direction of the anchor claws 6 and 6. In addition, auxiliary claws 8 and 8 projecting laterally are formed in the central portions of the anchor claw stop frames 7 and 7, and these auxiliary claws 8 and 8 are set in parallel with the anchor claws 6 and 6. There is.

Fitting rings 9 and 9 that come into contact with the boss portions 2a and 2a are fixed to the anchor claw shaft 5, and the fitting rings 9 and 9 prevent the anchor claw shaft 5 from moving left and right. Both ends of the anchor rope retaining ring 10 are fixed to both sides of the anchor claw shaft 5, and the protruding direction of the anchor rope retaining ring 10 is the extension direction of the anchor jaws 6, 6. Therefore, around the anchor claw axis 5, the anchor claws 6 and 6, the upper anchor claw stop frame 7, the lifting anchor rope stop ring 10 and the lower anchor claw stop frame 7 sequentially have a phase difference of 90 °. When the tip point 8a of the upper auxiliary claw 8 comes into contact with the upper end surface of the anchor trunk 2, the anchor claws 6 and 6 and the auxiliary claws 8 and 8 maintain a predetermined angle with the anchor trunk 2. The rotation of the anchor claw shaft 5 is prevented. It should be noted that one end of an anchor rope 11 is bound to the anchor rope attaching hole 4, and one end of a lift anchor rope 12 is bound to the lifting anchor retaining ring 10.

Since the anchor 1 of the present invention is configured as described above, as shown in FIG. 3, in the bottomed state, the tip portions 6b, 6b of the anchor claws 6, 6 slightly bite into the water bottom, and When the tip 8a of the lower auxiliary claw 8 slightly bites into the bottom of the water and the anchor rope 11 begins to become tense, the anchor claws 6 and 6 and the lower auxiliary claw 8 become deeper and deeper as shown in FIG. Not only does it bite into the earth and sand, but also the lower anchor claw stop frame 7 also bites into the water bottom sediment and when the anchor rope 11 becomes tense, as shown in FIG. 7 and the anchor 2 also bite into the soil on the bottom of the water and infiltrate, and anchor 1 becomes fixed.

The earth and sand excavated by the anchor claws 6, 6 and the lower auxiliary claw 8 pass through the space surrounded by the anchor claw stop frames 7, 7 and easily get over the anchor claw shaft 5, so that the anchor claws It does not hinder the infiltration of 6 and 6 and the auxiliary nail 8 on the lower side into the soil at the bottom of the water. Also, since the anchor claw frames 7 and 7 and the anchor trunk 2 are thin, it is easy to bite into the soil on the bottom of the water and infiltrate. Therefore, the anchor 1 sneaks deep into the sediments on the bottom of the water, and its holding power is great.

At the time of anchoring, by pulling up the anchor rope 12, the anchor claws 6, 6, the auxiliary claws 8, 8 and the anchor claw stop frames 7, 7 can be pulled in the direction opposite to the biting infiltration direction, It can be easily removed from the soil at the bottom of the water. The anchor 1 of the present invention is not only sandy but also rocky, the anchor claws 6 and 6 and the auxiliary claws 8 and 8 are press-fitted into the crevices and rock ledges of the bedrock for reliable and sufficient retention. Guarantee power.

[0013]

[Effect of the invention]

 Since the anchor of the present invention bites into the water bottom at the three places of the left and right anchor claws and the lower auxiliary claw at the time of landing, it can be held securely, and the anchor trunk and the anchor claw stop frame are also thin. As a result, the entire anchor sneaks into the sediment on the bottom of the water, and its holding power is enormous. Since the anchor claws are wide and wide, they prevent the rollover of the anchors and the inside of the anchor claw stop frame is a space, so the earth and sand can pass through, and the resistance to infiltration into the sand on the bottom of the water is extremely small. The anchoring is fast and reliable. Since the anchor trunk, the anchor claw, and the anchor claw stop frame are all thin, they are lighter in weight than conventional anchors and can reduce the work effort at the time of anchoring.
