DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor mounted on a ship.

[0002]

2. Description of the Related Art An anchor widely used in ships since ancient times has a bar-shaped anchor post having a rope / chain connection at its upper end. And a locking arm having a claw at the tip thereof. The claw is locked to an underwater rocky place or the like. However, the anchor of the above basic form may not be able to be lifted if the claws are strongly hooked on a rocky place or the like.
In addition, there is a problem that the above-mentioned specific shape is bulky on the ship and becomes an obstacle, and it is difficult to move and handle.

To solve the problem, there is a folding anchor disclosed in Japanese Patent Application Laid-Open No. 1-182189, in which a "locking arm having a cam portion" is hingedly connected to the lower end of the anchor post. A structure in which a "cam engaging portion having a biasing spring and capable of sliding the anchor post portion" is provided on the anchor post portion, and the cam portion and the cam engaging portion are engaged to hold and set a normal anchor form. When the locking arm is strongly caught on the rock, the engagement set of the cam engaging portion is disengaged against the spring urging force, and the locking arm rotates and breaks away from the rock, and on the ship, The locking arm can be folded and set on the anchor post side.

[0004]

The folding anchor of the above-mentioned known example has a structure in which the locking arm can be easily bent to the anchor post side, so that the locking arm put into the water is rocky due to its own weight falling force. When it hits strongly, etc., the locking arm can easily rotate and move to the anchor post side due to the impact force, the open leg shape peculiar to the anchor collapses, and it may not be possible to hook on rocky places, etc. Because of the complicated structure including the cam portion, the cam engaging portion, the biasing spring, and the like, maintenance for smooth operation of the components is required, which complicates the management and increases the cost.

[0005] The present invention provides a folding anchor which overcomes the above-mentioned disadvantages of the prior art.

[0006]

Means for Solving the Problems The folding anchor according to the present invention which solves the above technical problem is "fixed to the lower end of the anchoring bar of a single bar body and fixed to the base end to the left and right sides of the anchoring bar. Along with a pair of extending cantilever-shaped locking pieces, the locking pieces are detachably connected to free end portions of the locking pieces with claws at their tips, and
An arm-shaped anchor claw member that exhibits an upward inclined posture in the connection posture is provided, and the anchor claw member is hingedly connected to the anchor post portion by a link bar, and can be bent with respect to the anchor post portion. A locking groove connecting portion having a slot groove for receiving a free end portion and having locking means for engaging concave and convex engagement which is paired with the upper end of the slot groove at the free end portion; A structure in which the anchor member in the stopped state is set so as to be detachable from the locking piece by a predetermined downward or more external rotating force. "

That is, the folding anchor of the present invention has a structure in which an upper end is connected to a rope or a chain, and an anchor post portion serving as a center post of the anchor and a separate anchor claw member are hingedly connected by a link bar. A normal type of anchor is formed by connecting and locking the claw member to the cantilever locking piece at the lower end of the anchor post,
When the claw is strongly caught on a rocky place or the like and cannot be lifted in the underwater loading state, the anchor claw member is tilted down by the self-propelling force of the ship to disengage the connection lock so that it can be lifted, and the connection lock is manually operated. It is characterized by a structure that can be folded and set along the anchor post after removing work.

The locking means by the concave and convex engagement between the anchor member and the locking piece is provided by a pair of "pin and pin hole" provided inside the upper side of the slot groove and on the upper surface of the locking piece. The locking degree is set so that the locking and disengaging can be performed by the downward bending external force equal to or greater than the predetermined value.

[0009]

In the folding anchor according to the present invention having the above-mentioned structure, when the claw is strongly caught on a rocky place or the like and cannot be lifted, if the hull is pulled by its own hull propulsion, the anchor claw member is pushed down below the anchor post to be lowered. Since it is rotated and the connection between the claw member and the locking piece is released and loosened, it can be pulled up as it is. Then, on the ship, the connection lock is manually removed, and the anchor claw member is pivotally moved upward to be compactly folded and set along the anchor post.

Furthermore, even when the anchor claw member is strongly hit against rocks or the like when thrown into the water and receives a strong impact to rotate the anchor claw member above the anchor post, the upper portion of the slot of the slot groove is not affected. Since the locking means having the locking point enhances the degree of engagement by the external force of the impact, there is no risk that the anchor claw member comes off the locking piece, and the anchoring function is stabilized. Further, since the structure is simpler than that of the conventional structure, the molding is easy and the maintenance is easy.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, the folding anchor 1 of the present invention.
Is an anchor post 2 having left and right cantilever-shaped locking pieces 6A and 6B protruding left and right at a lower end 7 of a vertical single bar column 5 having a rope / chain connecting portion 4 at the upper end. It is constituted by a pair of anchor members 3A and 3B which are linked to the pillar portion 2 and are detachably connected and set to the free ends 8 of the locking pieces 6A and 6B, and the pair of locking pieces 6A and 6B are shallow. An elastic piece having a substantially U-shaped bottom shape, a central bottom portion of the U-shaped portion being fixed to a lower end 7 to be a fixed end, and having a shape inclined upward and downward on the left and right sides of the column 5 around the column 5. It has a beam form.

Then, the anchor members 3A and 3B are
A straight arm body 10 having a locking piece connecting portion 12 detachably connected to the free end 8 of the A. 6B is formed into a shape having a claw 11 at the tip end, and the vicinity of the locking piece connecting portion 12 and the anchor post portion The middle of the two pillars 5 is hingedly connected by a link bar 9 and can be bent around the hinge connection point as a center, and when bent off from the locking pieces 6A and 6B, the dotted line in FIG. It can be folded and set compactly along the pillar 5 of the anchor pillar 2 as shown in FIG.

On the other hand, the locking piece connecting portions 12 of the anchor members 3A and 3B (see FIG. 2A) are groove-shaped fittings for receiving and fitting the free ends 8 of the locking pieces 6A and 6B. The lower side 14 of the slot 15 is shorter than the upper side 13 of the slot, and the front end of the lower side 14 has a radius R joining to the back surface of the received free end 8.
The upper end 13 of the slot is provided with a screw pin 16 whose front end protrudes inward and which can be set forward and backward to engage with the locking hole 17 of the locking pieces 6A and 6B.

The anchor member 3 in the folded state
A. 3B is caused to cause slot 1 of locking piece connecting portion 12
5 faces the free ends 8 of the locking pieces 6A and 6B, and then puts the free ends 8 into the slots 15 thereof.
The screw pin 16 is advanced and set to a state where it is slightly fitted into the locking hole 17, and the anchor members 3A and 3B are locked with the locking pieces 6A and 6B.
In order to secure the three-dimensional posture of the anchor 1 at the bottom of the water, the numeral 20 in the figure is inserted before the water is inserted to lock the anchor 1. It is a known crossbar in which a lower end portion has a cross shape. And
The screw pin 16 is a bolt-shaped pin that is screwed into the screw hole on the upper side 13 of the slot and advances and retreats. By tightening the nut, the degree of engagement with the locking hole 17 can be set to an appropriate degree of engagement described later.

Then (see FIG. 2B), the locking pieces 6A
6B, when a strong external force P corresponding to the self-propulsion force of the ship on which the anchor 1 is mounted is applied in a direction to push the anchor claw members 3A and 3B downward, the curved surface portion 18 of the fitting slot 15 is engaged. The stopper pieces 6A and 6B are strongly pressed against each other and function as a rotation fulcrum of the rotational moment of the anchor members 3A and 3B due to the external force P. At the same time as the engagement piece connecting portion 12 is inclined to rotate, the free end 8 is also the anchor member 3A.・ Because it is slightly elastically deformed following 3B, the screw pin 16 and the locking hole 17 are disengaged from each other. As the rotation progresses, FIG.
As shown in (C), the shape of the locking piece connecting portion 12 and the degree of engagement between the screw pin 16 and the locking hole 17 are set so that the anchor members 3A and 3B hang down and become loose.

The folding anchor 1 of the above embodiment has the above-mentioned function. When the rope 3 cannot be pulled up due to the claw members 3A, 3B being caught on a rocky place at the bottom of the water, the claw members 3A, 3B are driven by the ship's own propulsive force. Into a loose shape at the bottom of the water, and can be lifted as it is. Then, even when the anchor claws 3A and 3B are strongly thrown into a rocky place or the like and receive strong external force in the direction opposite to the P when thrown into the water, the long slot upper side 13 of the fitting slot 15 is pressed against the free end 8. Since the degree of engagement between the screw pin 16 and the locking hole 17 is deepened, the anchor claws 3A and 3B cause the locking pieces 6A and 6B
There is no risk of falling off. And when it is not used on a ship, it can be folded and set compactly and compactly, so that it does not become bulky on the ship and becomes an obstacle, and it is easy to carry and handle.

The folding anchor according to the present invention is not limited to the above embodiment. For example, as shown in FIG. 4, the locking piece connecting portion 12 includes a pin 21 protruding inside the upper side 13 and the locking piece 6.
The shape may be such that it fits into the locking hole 17 or the locking recess 22 of the A.6B, or the shape that engages the projection 23 on one side with the locking groove 24 on the other side. Stop piece 6A
There is a change such as making the 6B an individual cantilever rather than an integral U-shaped body.

[0018]

As described above, the folding anchor according to the present invention does not have a risk of losing the anchor function due to the impact at the time of being thrown in water, can be pulled up by the hull propulsion even when it is difficult to pull up the rope, and is small and compact on board. It can be set, and, furthermore, has a practical effect that the structure is simpler than that of the conventional folding anchor and can be provided at a low cost, there is no need for complicated maintenance, and the convenience of the anchor user can be further improved.
