The present invention relates to a floating fender (or fender) that can mitigate the impact that may occur between a ship and a pier or a ship and a ship when the ship is docked at the pier. These fenders are divided into the attachment type to be attached to the quay or hull according to the installation method and the floating type to be installed by floating on the water surface.The attachment type is manufactured in the form of bolting to the structure such as the quay wall. Currently, the swivel structure loop is attached to both ends of the cylindrical fender with high buoyancy, and the chain of appropriate length is connected to the loop to fix both ends of the connection chain to the inner wall of the eyepiece. In this case, the cylindrical fenders generally use air fenders injected with gas into high-strength rubber tubes or foam fenders using foam materials. This type of floating fender has a higher shock absorption effect than the attached fender and floats on the surface of the water, so the fender automatically moves up and down as the height of the water rises and falls, so that the docking position of the ship is naturally adjusted. have. In particular, when the difference between tides reaches 7 meters, such as the west coast, several floating fenders are installed on the quay side by side. In general, fenders are used in combination with a floating type and an attached type. In the case of a floating type fender, the size of the fender needs to be changed according to the size of the ship and the length of the wharf. It should be formed to have inclined surface, but currently used fenders are produced with almost the same size and shape and have the disadvantage of being easily damaged by the impact from the outside. Considering the part, a large load goes to the fender, and in order to have a slope on the fender in order to prevent this, there is a disadvantage in that the production cost is expensive because a separate machining process is required. In particular, the air inside the fender is particularly weak to the external impact, and the foam is a disadvantage that is easily broken even a small impact.

The object of the present invention is to provide a floating fender (fender) having a necessary outer diameter and having a high cushioning effect while easily forming a shoulder portion at an angle desired by the user. .

In addition, an object of the present invention is to provide a floating fender that is light and excellent in shock absorption without being easily damaged by external impact.

In order to achieve the object as described above, to provide a floating fender excellent in cushioning effect,

A body formed by winding the sheet about one rotational axis by fusion by heat;

A stopper, comprising: a stopper, wherein a hollow tube is formed so that a thread is formed from the body so that an extended extension rod can enter and be fixed therein;

It may include a cover layer that covers the body so that the body is not easily separated and the end is coupled to the stopper.

 The stopper has two wings, and the wing toward the body may serve to prevent the body from falling over.

The cover layer may be to fix the wire wound several times.

The extension rod may include one or more nuts used to fix the extension rod and include a washer coupled to be movable in the space between the nut and the stopper.

The outer side of the cover layer may be formed of an elastic layer made of a resilient material.

A protective layer may be formed on the outer side of the cover layer by seamlessly attaching a sheet having a predetermined width about the same axis as the shaft of the body.

A protective layer may be formed on the outer side of the cover layer to seamlessly attach a sheet having a predetermined width in a direction perpendicular to the axis of the body.

A sheet may be attached to the outer side of the cover layer, but the sheet may be a sheet woven from fibers of the same thickness in a horizontal and vertical direction to seamlessly paste the sheet having a predetermined width to form a protective layer.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a view showing a floating fender according to the present invention. Figure 1 shows the body of the floating fender 10 according to the present invention is a body of polyethylene (PE), EVA (Ethylene-Vinyl-Acetate copolymer), such as a sheet of material and cut at the same time wound Form the body of the floating fender. Although the adhesive may be used to bond the body, the adhesive may be weakened by moisture, and the adhesive process is not easy and time and cost are high. do. Thermal fusion is a well-known technique and detailed description thereof will be omitted. In this way, thin sheets are fused, so unlike air-filled fenders or foam fenders, they are very light and light in water and resistant to external shocks, so they don't break or break easily. It has excellent buffering effect because it is dispersed in each layer of. A core may be used at the center of the body to facilitate the winding operation.

In addition, it is possible to adjust the outer diameter of the body as desired because the work by the winding method by the heat fusion method can easily create a floating fender of the desired size. In addition, it is possible to adjust the angle (shoulder) formed from the end of the body toward the center of the body by adjusting the width of the winding sheet. In general, the more the area where the ship and fender directly touch, the more easily the impact can be dispersed. Therefore, by adjusting the angle of the shoulder formed on the body it is possible to produce according to the ship that is anchored a lot in the pier.

As such, after forming the body by thermal fusion, the extension rod 14 is inserted into the center of the body. When the core is wound without a core, the extension rod may be inserted into the core or the extension rod and the core may be integrally formed.

A stopper is coupled to the extension rod. The stopper 15 has a hollow center in the form of a pipe and a wing (flange) having a radius larger than the radius of the pipe is formed on the outside of the pipe, thereby combining the body and the stopper. The body is fixed to the stopper by wrapping the outer surface of the rear body with the outer surface and tying the outer surface in the space between the wing and the wing of the stopper. Here, the inner wing of the stopper prevents the body from pushing outward. The stopper is coupled to both sides of the body so that the body is strongly coupled between the stoppers. The outer surface can be made of the same material as the tire cord paper. To connect the stopper and the extension rod, the extension rod is inserted into the stopper and then fixed by using a nut and a washer on the thread formed on the extension rod. In order to smooth the flow generated by the tension generated by the cord, etc., the washer is coupled with a predetermined space between the extension rods between the nut and the stopper. .

2 is a cross-sectional view of the components of FIG. The sheet is wound around the core to wind the body and the stopper is coupled thereto. The extension rod is filled with two nuts to prevent easy disassembly by tightening the two nuts, inserting a half-moon washer into the space between the nut and the stopper, and providing a space for the washer to move. Secure the flow space so that

3 is a cross-sectional view showing a state of reinforcement with a tire cord paper in the state of FIG. 2. After the tire cord paper is completely covered, the tire cord paper is bundled using a steel wire in a space formed between the wing and the wing of the stopper. The stopper 15 is attached to both sides of the body so that the entire body is surrounded by tire cord paper. In addition, the shock received by the body while supporting the body by the stopper is not only absorbed by the body itself but also has a certain fluidity in the horizontal direction as the washer is coupled to the nut that couples the body, thereby reducing the impact double. In addition, even if a large force from the outside pushes the body to the outside of the stopper, the tire cord is combined with the stopper to hold the body, so it is able to withstand any external force.

Fig. 4 shows a state in which the tire cord paper is reinforced in this way. The tire cord paper is used to completely cover the body and secure it on the stopper to prevent the floating fender from being loosened or dislodged when impacted. In this state, the outer surface of the fender is coated with an elastic layer made of polyurethane or polyurea. The elastic layer buffers the hard part of the outer side of the fender, and the soft part adds elasticity and prevents the body from being torn. .

5 and 6 are views showing an additional layer of coded paper in the horizontal and vertical directions outside the floating fender. In the horizontal direction, the paper is torn to a suitable width so that there is no seam, but when the paper is facing in the horizontal direction, the paper is overlapped with each other on the side. Fig. 5B shows the view as seen from the side. When attaching the cord in the vertical direction, attach it while rotating the fender. In this way, by attaching the cord to the outside, it protects the floating fender by not only catching the body when the external force is applied, but also preventing the cord from tearing in any direction.

In particular, the protective layer uses tire cord paper, nylon yarn, polyester yarn, etc., woven in the same thickness and width to equal the holding force against external force applied in the horizontal and vertical directions, so that external force is applied to both sides even if external pressure is applied to both sides. The distribution of is unbalanced, which prevents any part from tearing.

In this case, when forming the protective layer using a sheet woven from the same material in the horizontal and vertical direction, and the same thickness of the fiber yarn, even if the winding in any direction or the direction perpendicular to the axial direction, When receiving an external force has the same resistance to the external force there is an advantage that does not easily tear.

The design as described above has the effect of providing a floating fender that can be processed to have a good elasticity, excellent cushioning effect, and not easily broken and required outer diameter and shoulder angle.
