Abstract

PROBLEM TO BE SOLVED: To heighten buffer effect and to prevent rupture even in the case of excessive tension acting upon a linear member such as a rope by providing locking members for locking the floating body mooring linear member, at both ends of an elastic member with flexural elasticity in the state of protruding on one side. SOLUTION: A linear member 7 such as a rope with one end fastened to a floating body such as a boat and with the other end fastened to a stationary body such as a landing pier is fastened being wound around locking parts 3a, 3a formed at the tips of locking members 3, 3. When tension acts upon the linear member 7 by the movement of the floating body, the locking parts 3a of the locking members 3 incline due to being pulled by the linear member 7 in an opposite direction, and an elastic member 2 to which the base parts of the locking members 3 are fixed is bent. When the tension of the linear member 7 is relaxed, the elastic member 2 is restored by its elasticity. The damage of the locking parts 3a can therefore be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buffer 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 buffer for mooring a floating body used to reduce excessive tension acting on a linear member for use in a floating body.

[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 with a rope, a large tensile force acts on the rope mooring the floating body, and the floating body or the fixed object may be damaged. In order to prevent this, a shock absorber 11 as shown in FIG. 6 is used.

[0003] The shock absorber 11 has a central connecting portion 12,
A loop-shaped locking portion 13 made of an elastic material such as rubber provided at both ends of the connecting portion 12, and a rope 17 for mooring a floating body such as a boat or a ship is provided on the locking portion 12. Can be fastened. The tension applied to the rope 17 as the floating body moves is buffered by the expansion and contraction of the buffer 11.

However, when excessive tension acts repeatedly on the rope 17, the locking portion 12 of the shock absorber 11 may be extended and broken. If the locking portion of the shock absorber 11 is configured to be more rigid in order to prevent this, there is a disadvantage that a sufficient shock absorbing 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 floating body mooring shock absorber which is not likely to be broken even when a shock is applied.

[0006]

According to the present invention, there is provided a shock absorber for mooring a floating body, wherein a locking member capable of locking a linear member for mooring the floating body is provided at one end of each of elastic members having bending elasticity. The projection is provided so that the above-mentioned object is achieved.

[0007] In one embodiment, the elastic body is constituted by a laminate of a rubber layer and a metal plate.

In one embodiment, a screw portion is formed at a base of the locking member, the screw portion is inserted into through holes formed at both ends of the elastic member, and a nut is screwed into the screw portion. The engagement member fixes the locking member to the elastic member.

The operation of the present invention is as follows.

When the linear member is pulled in a state where the linear member is fastened to the tip of the locking portion provided at both ends of the elastic member of the floating mooring shock absorber, the tension is applied to the base of the locking portion. The elastic member is bent by acting, and when the tension of the linear member is loosened, the elastic member is restored by its elasticity. In this way, the tension of the linear member can be buffered by the bending elasticity of the elastic member.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

The floating body mooring shock absorber 1 of the present invention, as shown in FIG. 1, has locking members 3, 3 of a floating body mooring linear member projecting from one side of an elastic member 2 at intervals. It is configured.

The elastic member 2 has a core 20 having elasticity formed of rubber or the like, and outer plates 21 and 21 formed of steel plates or the like laminated on both surfaces of the core 20. Through holes 22 are formed at both ends of the elastic member 2, a screw portion 3 b is formed at the base portion, and a locking portion 3 a is formed at the tip portion. The screw portion 3 b of the locking member 3 is inserted through the through hole 22. The locking member 3 is fixed to the elastic member 2 by tightening with the nut 23. The core body 20 and the outer plate 21 are adhered with an adhesive or the like. The thickness of the core 20 and the outer plate 21 is not particularly limited as long as the elastic member 2 has a predetermined bending elasticity, but the thickness of the core 20 is preferably 1 to 10 mm, more preferably 2 to 5 mm. . The thickness of the outer surface plate 21 is set to 0.
It is preferably 5 to 5 mm, more preferably 1 to 3 mm. The width and length of the shock absorber 1 can also be set as appropriate. The width of the shock absorber 1 can be, for example, 1 cm to 5 cm, and the length thereof can be 30 cm to 60 cm.
The locking member 3 has a substantially T-shape, and the size of the protrusion of the locking portion 3a formed at the tip of the locking member 3 from the surface of the elastic member 2 is as follows.
For example, it can be set to 10 cm to 15 cm.

Hereinafter, the operation of the present embodiment will be described.

A linear member 7 such as a rope 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.
As shown in FIG. 1, both locking members 3, 3
a and wound around 3a. At this time, the linear member 7 is in a loose state between the locking members 3. When tension is applied to the linear member 7 due to the movement of the floating body, as shown in FIG.
Is inclined because it is pulled by the linear member 7 in the opposite direction, and the elastic member 2 to which the base of the locking member 3 is fixed is bent. When the tension of the linear member 7 is loosened, FIG.
As shown in (1), the elastic member 2 is restored by its elasticity. Thus, the tension of the linear member 7 stretched between the fixed object and the floating body can be buffered by the buffer 1. Since a large force does not act on the locking portion 3a of the shock absorber 1 from the linear member 7, the locking portion 3a is not damaged.

As shown in FIG. 3, the core 25 of the elastic member 2
May be formed of a steel plate, and the elastic members 2 may be formed by laminating elastic members 26, 26 formed of rubber or the like on both surfaces of the core body 25.

Further, as shown in FIG. 4, the base of the locking member 3 may be fixed to a frame 24 fixed to both ends of the elastic member 2 by welding or the like. The locking portion 3a at the tip of the locking member 3 is formed in a U-shape so that the linear member 7 can be easily locked.

Further, as shown in FIG. 5, the elastic member 2 may be composed of one or more laminated leaf springs or wire cords. Further, the width at both ends may be larger than the width at the center. When the width of the central portion is small, the elastic force of the elastic member 2 can be effectively exerted. Examples of the material of the elastic member 2 include a steel plate, a laminated steel plate, and a resin. The locking member 3 may be integrally formed on one side surface of the elastic member 2.

[0019]

According to the present invention, the tension acting on a linear member such as a rope can be buffered by the bending elasticity of the elastic member. Therefore, the buffering effect of the shock absorber is high and the linear member has an excessively large effect. Even when the tension is repeatedly applied, there is no possibility that the shock absorber is broken. In addition, when the elastic member is formed of a laminate of a rubber layer and a metal plate (steel plate), the elasticity of the rubber layer and the rigidity of the metal plate can be imparted, so that the elastic member has sufficient strength against the mooring force of the floating body. Can be obtained.
