JPH0727182A - Coupling tool for rope - Google Patents

Abstract

PURPOSE:To simplify connection and disconnection of a rope and to improve reliability by providing two hooks, positioned facing each other, with a stopper to hold the superposed state of the hooks. CONSTITUTION:Two hooks 1 and 3 integrally molded by using plastic are formed approximately in the same shape in a plane. A C-shaped hook part 5 is extended from a base part, the end of the base part is formed in a semicircular shape, and a rope hole 9 is formed approximately in the center of the semicircle. A stopper is needed to hold the two hooks 1 and 3 in a closed state and protrusions 19 are formed on the two surfaces of the second hook 3. When the hooks are closed, holes 21 in which the protrusions 19 are respectively fitted are respectively formed in the two plate-form parts 11 and 11 of the first hook 1 molded in a U-shape. In sealing of a rope 29 to a so formed coupling tool, the two hooks 1 and 3 are opened, and the rope 29 is inserted therebetween to firmly close. In this case, the protrusion 19 of the second hook 3 is fitted in the hole 21 of the first hook 1 and the hooks are not opened as far as the rope is not strongly pulled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for easily hooking and removing a rope, which is suitable for use in a fish net.

[0002]

2. Description of the Related Art An eggplant ring has been conventionally used for connecting ropes. The eggplant ring is a hook with a self-locking mechanism, which prevents it from coming off the hook even if the rope is loosened, and the connection and separation can be done easily, which is very convenient. However, the number of parts such as springs and pins is large, resulting in high manufacturing costs.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cheaper rope coupler.

[0004]

The connector of the present invention comprises two hooks whose hooks are opposed to each other and which rotate about a rope which is passed through a hole formed on the base side. And
Provide a stopper that holds both hooks in an overlapping state. In addition, one hook has a U-shaped cross section,
It is advisable to form the other hook flat so that it fits into the mating hook.

The stopper is simple, for example, if one hook is formed with a projection and the other hook is provided with a hole or groove into which the projection fits.

[0006]

[Function] Put a rope between both hooks in the open state, close the hook and hang the stopper. This will close the two hooks' mouths and keep the rope from coming off.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, this rope connector is composed of two hooks 1 and 3 integrally molded of plastic. When viewed in a plan view, both hooks have substantially the same (symmetrical) shape, and a C-shaped hook 5 extends from the base 7, and the end of the base 7 has a semicircular shape and the center of the semicircular shape. There is a hole 9 in the rope.

However, the shapes of both hooks are different from each other when viewed in cross section, and the first hook 1 is formed in a U shape and the second hook 3 is formed in a flat shape. That is, in the first hook 1, two plate-shaped portions 11 having the same shape are integrally connected by a connecting portion 13 along the outer half, and a gap 15 is formed between the two plate-shaped portions. Has been done. The second hook 3 is flat and is fitted into the gap 15 with the hooks facing each other (FIG. 2). A peripheral portion 17 is formed on the outer edge of the second hook for the purpose of reinforcement.

The second hook 3 can rotate about the base side, as shown by the chain line in FIG. Therefore, the peripheral portion 17 of the second hook is missing about 60 degrees on the base side. The defective portion is indicated by reference numeral 17a (FIG. 1).

Stoppers are required to hold both hooks in the closed state. To explain this, the projections 19 are formed on both sides of the second hook 3 and these projections 19 are formed when the hooks are closed. Fitting holes 21 are formed in the two plate-like portions 11, 11 of the first hook, respectively (FIG. 3). An eye 23 is formed on the back of the first hook 1, and a string 25 for opening is tied to this.

As shown in FIG. 4, this rope coupling tool is attached beforehand to the tip of the rope. That is, the first
The first hook and the second hook are combined, and the rope 27 is passed through the overlapped rope holes 9 to perform ice price processing.

To hook the rope 29 on this coupling,
Open both hooks 1 and 3, insert the rope 29 in between, and close firmly. Then, as shown in FIG. 3, the protrusion 19 of the second hook fits into the hole 21 of the first hook and cannot be opened unless strongly pulled. Thus, the hook mouth is closed and the rope 29 cannot be removed. The rope tension is 1st
And the hook portion 5 of the second hook cooperates with each other.

When the rope 29 is to be separated, the rope 29 in the hook is held down and the open cord 25 is strongly pulled. In this way, the stopper 18 is disengaged, the hook is opened, and the rope is disengaged.

[0014]

According to the connector of the first aspect of the present invention, the two hooks are combined so that they can be rotated about the rope passed through the base, and a stopper is provided for holding the two hooks in an overlapping state. It can be easily connected and disconnected, and since it has no pins or springs, it can be provided at low cost and has high reliability.

According to a second aspect of the present invention, one hook has a U-shaped cross section and the other hook has a flat shape so as to be housed in a mating hook. Can be made compact.

If the stopper is composed of the protrusion formed on one hook and the hole or groove provided on the other hook, the structure can be simplified.
