SOLUTION: A buffer material 1 for buoy mooring has an elastic part 2 wound with a buoy mooring linear member 7 in the periphery and lock parts 3 provided in both end parts of the elastic part 2 to insert the buoy mooring linear member 7 wound in the periphery of this elastic part 2. In the elastic part 2, a core material over between the lock parts 3 is arranged. Even when tensile force acts on the linear member 7, the elastic part 2 is prevented from being pulled and the periphery of the elastic part 2 is tightened by the linear member 7, acting as a buffer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for mooring a floating body, such as a boat, used for mooring a floating body, such as a pier, to a fixed object, such as a pier. The present invention relates to a floating mooring buffer used for reducing excessive tension acting on a mooring linear member.

[0002]

2. Description of the Related Art Conventionally, when mooring a floating body such as a boat to a fixed object such as a pier, a large tensile force acts on a linear member for mooring the floating body such as a rope, and the floating body or the fixed object is damaged. The cushioning material 1 shown in FIG.
1 is used.

[0003] The cushioning material 11 comprises an elastic portion
And a loop-shaped locking portion 13 provided at both ends of the elastic portion 12. A rope 17 is wound around the elastic portion 12 and further passed through the locking holes 16 of both locking portions 13. You.
The tension applied to the rope 17 with the movement of the floating body is buffered by the expansion and contraction of the buffer material 11.

[0004] However, when excessive tension acts repeatedly on the rope 17, the elastic portion 12 of the cushioning material 11 may be extended and broken. If the cushioning material 11 is made of a rigid material to prevent this, there is a disadvantage that a sufficient cushioning effect cannot be obtained.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a high cushioning effect and an excessive tension on a linear member such as a rope. An object of the present invention is to provide a cushioning material for mooring a floating body, which does not have a possibility of breaking even when it acts.

[0006]

According to a first aspect of the present invention, there is provided a cushioning material for mooring a floating body, wherein the elastic member is provided at both ends of the elastic member around which a linear member for mooring the floating body is wound. A locking portion through which the floating mooring linear member wound around is passed;
A core material extending between the locking portions in the elastic portion, thereby achieving the above object.

In one embodiment, the core is a metal member integrally embedded in the elastic portion and the locking portion.

The operation of the present invention is as follows.

A linear member such as a rope is wound around the elastic portion of the cushioning material for mooring the floating body, and the linear member is fastened to locking portions provided at both ends of the elastic portion. When the linear member is pulled, the elastic portion is not pulled by the core material provided therein, and the periphery of the elastic portion is fastened by the linear member. When the tension of the linear member is loosened, it is restored by the elasticity of the elastic portion. Thus, the tension of the linear member is buffered.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.

As shown in FIGS. 1 and 2, the floating body mooring cushioning material 1 of the present invention is provided at both ends of an elastic portion 2 around which a linear member 7 such as a rope is wound. And a locking portion 3 through which a linear member 7 wound around the elastic portion 2 is passed. A core member 4 extending between the locking portions 3 is disposed inside the cushioning member 1.

The shape of the elastic portion 2 can be variously changed according to the purpose. The elastic portion 2 is formed to be long so that the linear member 7 is wound around it, and its cross-sectional shape is circular, elliptical, square, or pentagonal. And the like.

The locking portions 3 are provided integrally at both ends of the elastic portion 2 in the longitudinal direction or by attaching separate members.
The locking portion 3 has a locking hole 6 through which the linear member 7 passes. The shape of the locking portion 3 may be a ring shape as shown in FIGS. 1 and 2, or an opening 8 as shown in FIG.
May be C-shaped or U-shaped. When the shape of the locking portion 3 is as shown in FIG. 4, the linear member 7 can be inserted into the locking hole 6 from the opening 8, so that the linear member 7 can be easily mounted on the cushioning material 1. Further, the locking portion 6 may be formed by a band or the like so that the linear member 7 is fixed to the elastic portion 2.

The core member 4 disposed inside the elastic portion 2 is formed to be long like the elastic portion 2. The core 4 may be a metal plate, a bar, a pipe, or a cord having a high tension. Examples of the cord material include, for example, nylon fibers, aramid fibers, polyester fibers, metal fibers, and the like. One or more of these may be used in combination.

The elastic portion 2 covers the core 4 with a predetermined thickness so as to surround the core 4. The thickness of the elastic portion 2 is usually 5 mm to 10 mm, though it depends on the material forming the elastic portion 2. The elastic part 2 can be formed of rubber, plastic, or the like having elasticity, and includes, for example, nitrile rubber, black linear member 7 rubber, hypalone, polybutadiene rubber,
Examples include ethylene-propylene rubber (EPM), ethylene-propylene terpolymer (EPDM), H-NBR, and thermoplastic elastomer.

As shown in FIG. 2, the reinforcing member 5 provided inside the engaging portion 3 may be integrally formed by extending the core member 4 and, in this case, the reinforcing member 5 is provided around the reinforcing portion 5. The locking portion 3 is formed by covering the elastic layer 9.

A linear member 7 having one end connected to a floating body such as a boat and the other end connected to a fixed object such as a pier is wound around the elastic portion 2 as shown in FIG. It is pulled linearly in the opposite direction through the 3 locking holes 6.
When a tension acts on the linear member 7 due to the movement of the floating body, the tension is converted into a force for tightening the elastic portion 2, and the elastic portion 2 is elastically deformed by tightening around the linear member 7. When the tension of the linear member 7 is loosened, it is restored by the elastic deformation of the elastic part 2.

In this way, the tension of the linear member 7 stretched between the fixed portion and the floating body can be buffered by the buffer material 1. Since a large force does not act on the locking portion 3 of the cushioning material 1 from the linear member 7, the locking portion 3 is not damaged.

The cushioning material 1 may be configured as shown in FIGS. In the cushioning material 1, an L-shaped bent reinforcing portion 5 is formed at both ends of a core 4 disposed inside the elastic portion 2, and an elastic layer 9 is coated around the reinforcing portion 5. A locking portion 3 is formed. Buffer material 1 having such a configuration
In this case, since the core member 4 is buried throughout the cushioning material 1, the force in the extension direction (longitudinal direction) does not act on the cushioning material 1 at all, and the elastic member 2 is pressed by the linear member 7. Works mainly. Therefore, the cushioning material 1 is not damaged.

As shown in FIG. 7, the locking portions 3 may be bent on the same side of the elastic portion 2 respectively.

[0021]

According to the present invention, the cushioning material has a high buffering effect, and there is no possibility of breakage even when excessive tension acts on a linear member such as a rope. Furthermore, since the cushioning material having such a function can be manufactured only by embedding the core material in the elastic portion, the manufacturing is relatively easy and the manufacturing cost can be reduced.
