Description

[Detailed explanation of the invention] (a) Industrial application field This invention is used for connecting devices, specifically connecting devices for ropes, strings, fishing lines, wires, ropes, etc., and more specifically for longline fishing in the open ocean. It also relates to connecting devices such as ropes that are subject to strong pulling force, such as those used to connect ropes (seats) of yachts.

(b) Conventional technology In net and longline fishing set in the open ocean, metal connections are used between the main line (stem thread) and the michi rope (michi thread), and between the michi rope and the hook rope. Tools (saru ring, untwisted) are used. These connections are
They come in a variety of shapes, but generally have rings at both ends, and many have rings that are rotatable relative to each other.

Generally, longline fishing is used for fishing for large fish such as tuna, and consists of continuous main lines of 400 m or more between the floats, and long lines hanging from the main lines between each float at intervals of about 50 m. He hung it down and attached a string or branch needle to it. Therefore, the forces of waves and swells that are constantly applied to these longlines, the pulling force of tuna caught on the hook, and the extremely large pulling force that is applied when laying the longline or pulling it up. It was.
Also, ropes and branch nets are subject to force in the twisting direction, so
Inconveniently, the opposite ends of the connecting device for tying the ropes must be rotatable relative to each other about their longitudinal axes. Longline fishing uses these connecting devices that can rotate freely in the longitudinal direction, and usually about 3,000 of them are used.

Also, in fishing such as trolling and bottom fishing, a small monkey ring (connecting device) was used between the Michi line and the Shikake line.

Alternatively, as a connection device for ropes (sheets) for hoisting and lowering sails on yachts, etc., a shackle is generally used that attaches and detaches a U-shaped straight rod. , was being put on and taken off.

Such connections are constantly or momentarily pulled under very strong tensile forces, so they must be constructed to withstand such forces. It was getting worse.

(c) Problems that this invention aims to solve Various shapes of monkey rings (untwisted rings) are known as connection devices used in longline fishing, etc., and all of them do not allow you to tie ropes, etc. at both ends. A ring is provided so that it can be done. Many connectors (monkey rings) are constructed such that the rings at both ends are rotatable in different directions with respect to the longitudinal direction.

However, even though the ropes are rotatable relative to each other only about the longitudinal axis, the sway caused by the waves comes from various directions, so there is a problem that the tied ropes tend to move loose.

Further, if the attachment and detachment is done by screwing, there is a problem in that it is very difficult to attach and detach on a swaying ship, and it is often virtually impossible to attach and detach.

However, longline fishing, sailing, etc. always require work at sea, and in order to withstand even stronger external forces, ropes, etc. that have been tightly tied to the ring of the connecting device, must be untied at sea. Don't do anything,
In the case of fishing such as longline fishing, if an accident occurred, the rope was cut and the rope and hook at the end, including the connecting equipment, were discarded.

In addition, once the rope is tied tightly, even after the longline has been pulled up, it is difficult to untie the connecting device from the rope because the work is done at sea, and there is a risk that the hook line will be cut along with the connecting device. This is a common practice, and the consumption and disposal of these connectors has become a problem.

Also, in fishing such as trolling and bottom fishing,
When trying to replace Harris on a rocking boat,
It is necessary to tie and untie the Harris or the Harisu to the rings at both ends of the connecting tool that connects the Harisu to the Harisu, which is extremely troublesome for beginners.

In the case of yachts as well, there was a problem in that when at sea, work was required to be done quickly amidst the tilting and swaying caused by the wind, making attaching and detaching the shell extremely difficult.

The object of this invention is to provide a connecting tool that allows separate members to be attached and detached from the attached connector with very easy operation.

(d) Means for solving the problem This invention is based on the invention that a rotary ring body that is rotatable in the longitudinal direction of the connector body and a detachable ring body that is detachable from the connector body are connected to the connector body. provided on opposite sides of the main body, an elastic body provided within the connector main body, and a detachable hole having an open end elongated in one direction on the insertion side of the detachable ring body of the connector main body; A long groove is provided in the inner cylindrical end in a direction almost perpendicular to the attachment/detachment hole, and pedestals of different heights are provided alternately on the left and right sides of the groove, so that the insertion body of the detachable ring body resists the outward biasing force of the elastic body. The above-mentioned problems are solved by proposing a connector which is configured to be press-fitted into the groove and then rotated approximately at right angles to be attached to and removed from the groove.

Further, the rotary ring body is configured to be rotatable and tiltable with respect to the connector body as claimed in the claims.

Further, in order to further enhance attachment/detachability, the connector main body is configured to have a large number of linear uneven portions in the longitudinal direction of the outer periphery of the cylinder.

(E) Function The rotary ring provided on the connector body has a ring to which a rope or the like can be tied, and is connected to the connector body so as to be rotatable in the longitudinal direction of the connector body.

The detachable ring on the opposite side of the connector body has a ring to which a rope or the like can be tied, and can be attached to and detached from the connector body. This attachment/detachment involves inserting the insertion body of the detachable ring through the attachment/detachment hole, press-fitting it into the connector body against the biasing force of the elastic body within the connector body, and rotating it approximately at right angles, that is, approximately 1/4 turn. By doing so, the insert body is pressed and engaged with the groove inside the connector main body by the elastic body.

Similarly, resist the biasing force of the elastic body and press fit a little,
It can be removed by rotating it approximately at right angles in the opposite direction.

At the time of mounting and dismounting after rotation, engagement and disengagement are easy with the help of the biasing force of the elastic body directed toward the outside of the connector main body.

When a rope or the like is tied to the rings of the rotary ring and the detachable ring, the two rings are rotatable relative to the connector main body and the longitudinal axis.
Furthermore, since the structure of the claims allows the connecting device to be tilted freely with respect to the main body, there is little friction between the ring and the rope.

The detachable ring attached to the connector body is
It will not come off from the connector body unless it is pressed in against the spring and rotated further.

(f) Example This invention is shown in the first example, which shows the front view.

The cylindrical outer circumferential surface of the connector main body 1 is provided with a large number of linear uneven portions in the longitudinal direction of the cylinder. This is to increase the frictional force when rotating each other when attaching to and detaching from the detachable ring body 3.

The rotating ring body 2 is composed of a ring 7, a locking body 8, and a continuous portion 9, which are integrally formed, and the locking body 8, which has a larger diameter than the rotation hole 5, is located inside the connector main body 1. In this embodiment, the locking body 8 has a disc-like shape, but it has a spherical shape,
Even if it has a cylindrical shape, a polygonal column shape, etc., it is sufficient that it is larger than the diameter of the rotary hole 5 and does not pass through the hole. The disk shape is formed by cutting the periphery of the surface facing the spring 4 and slidably fits into the bowl-shaped recess of the annular washer 10 provided between the spring 4 and the locking body 8. Thereby, the locking body 8 pushes the annular washer 10 and is freely tiltable with respect to the longitudinal direction of the connector main body 1.

The ring 7 is an annular body that can be used to tie things such as ropes, and has approximately the same outer diameter as the connector main body 1.
It is sufficient that it is at least larger than the inner diameter of the rotating hole 5.
The continuous portion 9 is a rod-shaped body that integrally continues the ring 7 and the locking body 8, and its diameter is smaller than the inner diameter of the rotation hole 5 by a distance.

The detachable ring body 3 consists of a ring 11 and an insert body 12. The ring 11 is an annular body to which a rope or the like can be tied, and its diameter is approximately the same as the diameter of the connector main body 1. The insert body 12 is composed of a rod-shaped portion 13 and engagement protrusions 14 protruding from the rod-shaped portion 13 to the left and right. The engagement protrusion 14 is configured to be opened 180 degrees at an appropriate distance from the ring 11. The insert body 12 is

The distance of the engagement protrusion 14 from the ring 11 and the distance of the high base part 16 and low base part 17 from the end surface of the connector main body 1 are as follows: the low base part 17, the engagement protrusion 14, and the high base part 16 in decreasing order. In addition, the base parts 16, 17
You can also create them at the same height as in . Detachment hole 6
The shape on the end surface of the connector main body 1 is that of the detachable ring body 3.
The engaging protrusion 14 and rod-shaped portion 13 of the insert body 12
However, it has a shape that can be entered with a slight gap, and in this embodiment, the planar shape is an elongated rectangular central portion that bulges into the circular cross section of the rod-shaped portion 13. The direction of this elongated rectangular shape and groove 1
The orientation of 5 is formed at an approximately 90 degree angle,
The width may be any width as long as the engaging protrusion 14 can be inserted and engaged. Reference numeral 18 denotes an annular washer, which is provided between the insert body 12 and the spring 4, into which the rod-shaped portion 13 of the insert body 12 can be freely inserted, and comes into contact with the engagement protrusion 14 of the insert body 12 through the ring portion.

In this embodiment, the elastic body 4 is a metal body constituting a spring covered with a coating of synthetic resin, but it may also be made of a material other than the spring that has elasticity and is water resistant, such as rubber, soft synthetic resin, etc. It may be constructed from the following materials.

The connector of this embodiment includes a ring 7 of a rotating ring body 2,
Tie ropes 19 to the rings 11 of the detachable ring body 3, insert the insert body 12 of the detachable ring body 3 into the attachment/detachment hole 6, and resist the spring 4 in the connector main body 1.

is rotatable around the rod-shaped portion 13, and when rotated approximately 90 degrees, the engagement protrusion 14 hits the groove 15,
By loosening the press-fitting force, the engaging protrusion 14 engages with the groove 15 due to the biasing force of the spring 4. Of course, the ropes may be tied after the detachable ring body 3 is attached to the connector main body 1. In this case, it is better to tie the rope to be discarded, such as a Harris rope, to the attachment/detachment ring 3.

Also, when detaching the detachable ring body 3 from the connector main body 1, press the detachable ring body 3 once against the spring 4, turn it about 90 degrees at the low base part 17, and then
4 through the attachment/detachment hole 6. In this case as well, since the spring 4 is biased outward, it can be easily removed.

In this example, the length of the entire connector is approximately 50 mm, the length of the connector main body 1 is approximately 25 mm, and the width is approximately 10 mm, but the size varies depending on the object for which the connector is used. .

6 and 7 show other embodiments, in which a working hole 19 is formed on the extension line of the groove 15 in the cylinder of the connector main body 1.
It has a hole in it. This working hole 19 makes it very easy to work on the inside of the connector main body 1. Further, in this embodiment, the base portions 16,1
7 are formed at the same height to improve workability.

(g) Effects of the invention Therefore, according to this invention, a detachable ring is provided in a connecting device for connecting ropes, and an appropriate rope (type of Harris, wire, etc.) is tied in advance to the detachable ring. It can be installed by simply press-fitting the attachment/detachment ring into the connector body and turning it approximately one-quarter of a turn, and it can be detached by doing almost the opposite operation, making attachment and detachment much easier than before. effective.

Therefore, even when working in places where shaking is common, such as on a ship, there is no need to untie the ropes as in the past, and ropes can be replaced and thrown away very easily. effective.

In cases such as long-line fishing, if only the detachable ring is discarded and replaced, the main body of the connecting device and the rotating ring remain, resulting in a significant saving in materials.
