Description

[Detailed description of the invention] anchor Technical field The present invention relates to an anchor for mooring a watercraft to the bottom of the water.

Anchors are used to moor ships to prevent them from shifting due to ocean currents or wind. Of course it's well known. Such anchors are usually flexible ropes, cables or chains. It is tethered to a ship and has a round hook that hooks onto the bottom of the water to prevent the ship from moving. . Squid hooks usually pierce the bottom of the water when force is applied from the cable, ensuring secure protection for the ship. It is designed to hold.

In order to pull the anchor out of the water, it is necessary to overcome the force holding the squid hook. be. To do this, apply a vertical force that dislodges the object on top of the key. I'll get it. However, if the squid hook is caught on a hard object such as a rock at the bottom of the water, If this happens, vertical tension may damage the anchor. Therefore, in such cases the ship is suitable. actually move and apply a force to the cable in a direction that causes the anchor to dislodge from the object. It is. Danforth type anchors that have become popular recently - usually has a spade-shaped squid hook on the support. The squid key is centered around the pillar. The real axis rotates, and a stopper (5 tops) limits the amount of movement. This way Since the column is held at an acute angle to the latch, any force applied in the direction of the column will cause The hook will dig into the bottom of the water and moor the ship. However, the fish at the bottom of the water Because there is a stopper that moves to make the squid bite, it is difficult to feed the squid hook from the bottom of the water. It is impractical to have to move for the purpose of extraction. to that movement Therefore, a very large force is applied to the support, and the young hook may get caught on a rock. This will cause damage to the anchor.

Another problem with anchors that apply force to make squid hooks bite is when using squid hooks. Normally, the squid hook will come out from the bottom of the water with the opposite force to the one that makes it bite into the bottom of the water. That's what I mean. Thus, if a change in tide or wind direction causes the ship to pull out its anchor, You can also move around. This is clearly unwell and also This is also the reason why other stoppers are provided on base-type anchors. Other stock The force in the opposite direction to the par will pull the squid hook vertically off the seabed through the tip. It is something that works.

This provides some resistance to movement. However, as mentioned in Nagazude , such a stopper makes it difficult to hook the anchor or pull it out from the seabed. .

Disclosure of invention Therefore, one object of the present invention is to provide an anchor that eliminates or alleviates the above-mentioned defects. It is to be.

According to the present invention, the following anchor is provided. i.e. connected to a flexible fastening device. A column connected to the column, a squid hook assembly that rotates around the column, and the column. The anchor installed on the seabed is stuck into the seabed and is held in a leading position. edge and said fastening device located at a distance from its leading edge. As if the leading edge were pulled out from the surface it was sticking to by the force of and a sprag means for resisting movement, the sprag means being driven into the seabed surface. Then, rotate the squid hook around the support and continue to embed the leading edge into the seabed surface. It is something that makes you The stopper device limits the rotation of the shaft, and the stopper The force in the direction of pulling out the leading edge and the support are constructed so that they are substantially in a straight line. It is preferable to use Rotate the post against the anchor by using sprag means. It is now possible to connect the movable hook so that it is in line with the direction in which it exits from the seabed. Become. Even if the leading were to come off the seabed due to changes in ocean currents or wind direction, the ski The plug is hooked onto the seabed and allows the cyan anchor to work effectively against the ship.

Although the example shows a releasable stopper in the form of a conventional anchor, the anchor This does not prevent the car from being released or reset.

Bu The lock has a protrusion 66 accommodated in the elongated hole-shaped portion 62. is supported by a shoulder 68. The shape of block 64 is such that its end surface 70 is It contacts the wall of the cam track 56.

A pair of slots 72.74 are formed at opposite ends of each of the links 26.28. has been done. The total lengths of these slots are approximately equal, and , for receiving projecting pins 76° 78 attached to opposite ends of the subordinate link 80. It's becoming a sea urchin. The spacing between pins 76.78 is such that subordinate link 80 is The four screws are arranged so that they can freely slide by an amount equal to the total length of the slots 72 and 74. ) 72.74 corresponds to the distance between the longitudinal intermediate portions. dependent link 80 is located between links 26 and 28 and is adjacent to pin 7 on block member 3. 6 projects beyond the outer surface of the link 26.28 into the cam track 56.

Similarly, the pin 78 proximate to the boss 50 should not extend beyond the outer surface of the link 26,28. It protrudes in the direction of 16 and 18.

Squid key 14. Each of L6 has an end surface 82 from which a pin 20 protrudes. End face 82 is approximately diamond-shaped, and the pin 20 extends from the corner of the end face 82. Located in the most remote location. The end face 82 has a pair of holes that partially surround the boss 50. Kidney-shaped protuberances 84 and 86 are formed. Each ridge has an inner and outer curved surface 8 88.90, and one end of each curved surface 88.90 smoothly intersects. The other ends of each cross each other and are the abutment surfaces? 2 is formed. Contact Surface 92 is configured to engage pin 78 when one end of dependent link 80 is moving. Also, when the other end of the dependent link 80 is moving, the other end of the dependent link 80 is It is located so that it is raised away from the contact surface.

The end face of the squid hook 16.18 has a squid hook leading edge 94. Intersects with one end. This leading edge 94 is almost the same as the anchor. The body is chamfered to form a piercing edge.

A pair of outwardly extending lips 96.9B are provided at the opposite end of the end surface 82. These lips 96,98 are attached to the wall 100 to which the stop member 22 is attached. Therefore, they are connected. Rip 96 is almost flat 8 of Ikashi Kagi 16.18 A stop member that can be attached freely to the surface where the anchor is inserted is branched from the main body. is forming.

To assemble the anchor components, the dependent link 80 and block member 38 are assembled. is placed between the links 26 and 28, and the pins 76 and 78 are inserted into the respective slots. Both studs 36 are inserted into the holes 54. An annular elastomer ring 64, - placing the slap 66 in the curved recess of each ear and placing the flap 66 in the rectangular part 62; let it be placed Ear 46 by positioning the end of pin 76 within cam track 56 on the cheek 44, and then drive the rivet 48 into the hole 50.52 to reset it. The ear 46 is attached to the block member 58 by tightening the bed.

Next, after attaching the pin 20 to the latch hook 16, it is inserted through the hole 30 and the boss 52. Insert into the key 18. Also, insert the fastener 24 into the stop member 22. Fasten with a suitable fastener to prevent pin 20 and fastener 24 from being removed. This conclusion The key 16, 18 now rotates integrally with respect to the pin 20. pin The end of 7B is located close to end face 82 and between abutment surfaces 92 of ridges 84.

Next, to describe the operation, the couple 42 is attached to the U-shaped hook 40, and the anchor 1 0 to the place where the ship is to be held, the struts 12 are determined by the spacing of the contact surfaces 92. It is rotatable over a range of movement. Squid hook assembly 14 gets caught on the seabed And Leading Edge 94 is Submarine 9 Tokusho 58-5U191J3 (5) Take a position where you can pierce. When a force is applied to the cable 42, the strut 12 pulls the pin 20 The pin 76 is rotated until the pin 76 comes into contact with the contact surface 92. More couple 4 2, when a force is applied in the direction of the extension of the pillar 12, the leading edge ? 4 is the ocean floor It stabs into the sea, and is unfazed by the movement of the ship.

In the condition shown in Figure 3, links 26 and 28 are pivotable around the pin by angle A. be. Similarly, depending on the depth of the abutment surface 92, the block member 38 may engage the abutment surface 92. Rotate around stud 36 by angle B without movement of mating pin 78. Free to move. This accommodates ridges and tidal movements normally associated with moored vessels. can.

If the wind direction or current changes, or if the anchor is to be hoisted, the cable should be The angle of the lever 42 changes as shown in FIG. In this position, the block member 58 is Rotate the link 360 times, consisting of the shaft formed by the tad 36, and The ears also move. The pin 76 located within the slot 72 is inserted along the cam track 56. Due to the eccentricity of the cam track 56, the pin 76 will move. It moves along the longitudinal direction of the slot 72. Due to this longitudinal movement, the scissors 78 The links 26 and 28 are released from engagement with the abutment surface 92, and the links 26 and 28 move the bottle 200 times. The block member does not rotate until it comes into contact with the stop member 22, and as a result, the block member 38 serves to reverse the rotation of the stud 36. The 900 curvature of the outer curved surface is This allows the contact point of the pin 78 in the cam track 56 and the outer curved surface 90 to chosen so that the distance between them is constant. Links 26 and 28 are stop members 22 When it comes into contact with.

The block member 38 is aligned with the links 26 and 28 by the cable. It can be rotated until In this position, pin 76 engages end face 70 of block 64. match.

When force is applied to the cable 42 in this state, the squid locking device is activated as shown in Figure 5. The device can be removed without great difficulty even if it is located directly beneath a stone. Wear.

If the anchor is to be hoisted, after releasing the anchor from the seabed surface, the cable 42 A vertical force is applied to the anchor through the anchor, and the anchor is pulled up onto the vessel. However However, if the direction of the cable 42 changes due to changes in wind or current, the cable moves the anchor assembly along the seabed while allowing the vessel to drift. will continue.

Such movement along the seabed surface is inhibited by the ribs 96. Rib 96 is squid Depending on the shape of the anchorage assembly, when the anchorage assembly is removed from the seabed surface, it will be larger. Positioned at a large thrust angle. Therefore, the ribs 96 plunge into the seabed and anchor is pulled along the seabed surface and the hook assembly is pulled against the pin 2 against the strut 12. Try to rotate around 0. When the column 12 rotates, the pin 78 moves along the curved surface. and axially displaces the dependent link 80 with respect to the link 26°28. This strange thing The position is adjusted by compression of the nidistomer block 64. Squid key assembly 14 continues to rotate, and the pin 78 moves to the contact surface 92, as shown in FIG. The elastomeric block is then positioned until the pin 76 is aligned with the cam track 56. Then, the subordinate link 80 is deflected. The block member 38 is connected to the link 26.28. At the same time, the cable can be rotated with The anchor 12 is continued to be pulled until it passes and descends into contact with the seabed surface. this In position, pin 78 again restricts movement of the anchor key assembly relative to post 12, and As a result, the squid hook assembly moves continuously along the seabed and reaches the leading edge. 94 stabilizes the piercing cyan anchor 10 on the seabed surface.

Therefore, the anchor device supports the anchor in the direction opposite to the direction of the load applied to the anchor. It acts as a reset and also allows the anchor to be moved easily so that the anchor can reach the underwater target. It will be understood that it is possible to move the vessel to a position where it engages. cam truck 56, a release consisting of a pin 7B cooperating with a subordinate link 80 and an abutment surface 92 The use of possible stopping means prevents the anchor from moving in the normal manner and penetrating the seabed. We guarantee that.

Alternative arrangements of releasable stop members are, of course, possible within the scope of the invention. be. For example, the subordinate link 8° is moved within link 26, 28 by slot 72. Rather than being regulated by the block member 38, it is also possible to directly support the block member 38. So While devices such as The anchor is held in the unlatched position so that the dependent link and link It is preferable to prevent rock debris from entering between the 26 and 28.

The general bulbous nature of the hook assembly near pin 20 is the leading edge. In addition to assisting in setting the 94 at the correct piercing angle, the ribs 96 This assists in increasing the driving angle of the sprag means.

The pivoting of the strut assembly through its entire range of motion relative to the latch assembly is also important for ships. To facilitate the accommodation of anchors onboard ships. A preferred containment device is shown in FIG. In Figure 0, the anchor 1D is housed in a housing 110. Housing 1 10 is generally divided by a diamond-shaped vertical wall 112, and the vertical wall 112 has a pair of flaps 114. and the flap 114 extends from the wall 122 toward the center of the housing 110. There is. Walls 114 located parallel to each other terminate in flaps 114 and provide support for the anchor. It provides a groove into which the pillar can fit. A guide path 118 is cut into each wall 116. It consists of a straight section 120 and a curved section 122. Each of the ears 46 has a link A stud 124 is provided which is located away from the pivot axis of the block member.

To accommodate anchor 10 in housing 110, block member 38 is 26. Rotate to a position approximately 90 degrees relative to 28 to release the column from the hook assembly. do.

Additionally, the edge 94 of the squid hook is placed under the flap 114 and the rib 96 is supported by wall 112. The square column 126 is located between the stop member 22 and the pin 2D. The lock is inserted through the opening and held in place by a linchpin or similar means. Ru. At that time, the stud 124 is placed at the joint between the straight part and the curved part 121, 122. Until the stud 124 is in position, the straight portion 120 and the link 2 that rotates the bottle swivel Located close to 6.28. The block member 38 then rotates and the stud 1 24 lowers the curved portion 122 until the block member and link are aligned. therefore , the anchor 10 is securely retained within the housing 110.

The edge 94 of the squid is protected under the flap 114. releasing the anchor Relatively simple, simply rotate the block member to release the stud from the curved section It is only assumed that the bottle rotates the bottle 200 times.

If you prefer, use a lynch pin to hold the latch lock assembly in place. Instead, the lower end of the anchor is secured with a pair of wedge blocks 128 shown in dotted lines in FIG. can be supported.
