Description

  The present invention relates to a fender.

  When a ship at the berth or a moored ship is shaken by waves or winds, or when ships collide while sailing, the fender attached to the hull suppresses damage to the hull. As an example of such a fender, Patent Document 1 discloses a configuration in which a buffer body is secured to a hull by a plurality of band members.

JP 2014-73825 A

By the way, in Patent Document 1, since the band member is wound around the buffer body so that the band member covers the outer surface portion of the buffer body, for example, when the structure at the pier and the buffer body collide, the band member is damaged. However, there is a case where the buffer body is fixed by the belt member. As a result, the shock absorber may fall off the hull.
The objective of this invention is providing the fender which made it possible to suppress that a buffer body falls from a hull.

  A fender for solving the above problems includes a cushioning body that is a foam, an exterior body that covers the cushioning body, and a string body that attaches the cushioning body and the exterior body to a hull. The body includes an inner surface portion which is a portion for facing the hull, and an outer surface portion located on the opposite side of the inner surface portion, and the string body is between the outer surface portion and the buffer body. And is passed through the exterior body.

  According to this configuration, the impact on the string body from the outside of the fender body toward the outer surface of the exterior body is mitigated by the exterior body located outside the string body. Thereby, possibility that a string will be damaged and cut | disconnected by the impact from the exterior of a fender can be suppressed. Therefore, the fender can be prevented from falling off the hull.

  In the fender, a passage sheet having a belt shape extending along an extending direction of the string body is fixed to an inner surface of the outer surface portion of the exterior body, and the passage sheet includes the string body and the strap body. It is preferable that it is located between the buffer bodies and defines a passage through which the string body passes.

According to this configuration, since the contact between the string body and the buffer body is suppressed by the passage sheet, when the impact is applied from the outside of the fence body, or the fence body is attached to the hull by the string body. At this time, damage to the buffer body due to the string body biting into the buffer body can be suppressed. In addition, since the string body is passed by the passage sheet, when seawater or rainwater enters the exterior body through the space between the exterior body and the string body, the seawater or rainwater enters from one end side of the path sheet. Then, it flows out of the exterior body through the passage sheet and from the other end side of the passage sheet between the exterior body and the string body. For this reason, it can suppress that seawater and rain water permeate the inside of a fender.
In the fender, the exterior body includes a tarpaulin sheet, and the sheet preferably includes the outer surface portion and the inner surface portion.
According to this structure, since an exterior body is hard to be damaged, it can suppress that seawater and rainwater permeate into a buffer body through an exterior body.

  In the fender, the inner surface portion is composed of a plurality of portions in the sheet, and the sheet has a hook-and-loop fastener portion for fastening the portions of the inner surface portion to each other. It is preferable to further provide the part.

According to this configuration, since the gap between the portions constituting the inner surface portion is suppressed by the hook-and-loop fastener portion, it is difficult for seawater and rainwater to enter the buffer body from the inner surface portion through the portion.
In the fender, the inner surface portion preferably covers the entire portion of the shock absorber facing the hull.
According to this configuration, seawater and rainwater can be prevented from entering the inside of the fender.

  In the fender, the inner surface portion includes an upper fabric and a lower fabric covered with the upper fabric, a tip portion of the lower fabric is covered with a tip portion of the upper fabric, and the lower fabric is And an intermediate portion not covered by the upper fabric. The intermediate portion includes a bent portion in which the lower fabric is bent in a pleated shape, and includes a through-hole penetrating a tip portion of the upper fabric and a through-hole penetrating the bent portion. A connector for connecting the fabric and the lower fabric may be passed.

  According to this configuration, the inner surface portion is composed of two pieces of fabric, and the tip portion of the lower fabric is covered with the tip portion of the upper fabric. Therefore, the inner surface portion composed of two pieces of fabric can suppress the intrusion of seawater and rainwater into the inside of the fender as well as the inner surface portion composed of one piece of fabric. Become. In addition, when the upper fabric and the lower fabric are fastened, the bent portion in which the lower fabric is folded in a pleated shape and the leading end portion of the upper fabric are fastened by the coupling body. At this time, since the bent portion of the lower fabric is a portion that is not covered by the upper fabric, only the side facing the inner surface portion is configured even if the tip of the lower fabric is covered by the tip of the upper fabric. Thus, it is possible to perform an operation of fastening the upper fabric and the lower fabric. In addition, the bent portion of the lower fabric is a portion where the lower fabric is doubled, and the connecting body is passed through the bent portion, so that the strength against the tension of the connecting body is sufficiently secured by the lower fabric. It is also possible to do.

  In the fender, the buffer includes a first foam layer facing the inner surface of the inner surface portion, and a second foam layer laminated on the first foam layer and facing the inner surface of the outer surface portion. It is preferable.

  According to this configuration, the physical properties such as the compressive stress and the restoring force of each foam layer are different between the first foam layer and the second foam layer, and thus the function of the first foam layer and the second foam layer The shock absorber is provided with another function of the. For example, the contradictory requirements for a shock absorber can be met. An example of this contradicting requirement is to buffer the impact from the outside of the fender and restore the distortion caused by the impact.

  According to the said fender, it can suppress that a buffer body falls out of a ship body.

  Hereinafter, an embodiment of a fender will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the fender 1 includes a cushioning body 10 that is a foam, an exterior body 20 that covers the cushioning body 10, a plurality of string bodies 30 attached to the exterior body 20, and an exterior body In order to maintain the state where the body 20 covers the buffer body 10, a plurality of coupling bodies 40 that couple the ends of the exterior body 20 to each other are provided. In the present embodiment, the fender 1 includes three string bodies 30 and six connecting bodies 40 (only four are shown in FIG. 2). The string 30 has a belt shape. An example of the connection body 40 is a rope. In addition, the number of the string 30 and the connection body 40 can be set arbitrarily.

  FIG. 3 shows an example of a structure for attaching the fender 1 to the hull 110 of the ship 100. In FIG. 3, a plurality of fenders 1 are arranged on the bow portion 120 of the hull 110 from the bow side toward the stern side. In each fender 1, the first attachment portion 31 of the string body 30 is fixed to a bow rail 130 provided on the deck of the hull 110, and the second attachment portion 32 of the string body 30 is provided below the hull 110. It is fixed to the pole 140. Thus, when the ship 100 is berthing or when the ship 100 is shaken by waves or wind while the ship 100 is moored, the hull 110 and the berthing surface are between the hull 110 and the berthing surface. It is possible to prevent damage to the hull 110 and the berthing structure due to the pressing force and frictional force acting on each other. Further, when the ship 100 collides with another ship, the fender 1 can prevent the ship body 110 from being damaged by avoiding a direct collision between the ship 110 and the ship of another ship.

  As shown in FIGS. 1 to 3, the exterior body 20 includes an inner surface portion 21 that is a portion for facing the hull 110, and an outer surface portion 22 opposite to the inner surface portion 21. The plurality of coupling bodies 40 are located closer to the inner surface portion 21 than the buffer body 10. The plurality of string bodies 30 are passed through the exterior body 20 through between the outer surface portion 22 and the buffer body 10.

  As shown in FIG. 4, the buffer body 10 has a rectangular parallelepiped shape. The shock absorber 10 is a two-layer structure configured by a laminate of the first foam layer 11 and the second foam layer 12. When the shock absorber 10 is covered with the exterior body 20, the first foam layer 11 faces the inner surface of the inner surface portion 21 (see FIG. 2) of the exterior body 20, and the second foam layer 12 is the outer surface portion 22 (FIG. 1). (See). For this reason, in a state where the fender 1 is attached to the hull 110 (see FIG. 3), the first foam layer 11 is located closer to the hull 110 than the second foam layer 12. The ratio (T1 / T2) of the thickness T1 of the first foam layer 11 to the thickness T2 of the second foam layer 12 is preferably 0.2 or more and 5.0 or less. The thickness T1 is more preferably thicker than the thickness T2 of the second foam layer 12.

  An example of the first foam layer 11 is a foam of a styrene-modified polyolefin resin having a foaming ratio of 30 times. The first foam layer 11 of the present embodiment is a foam of a styrene-modified polyethylene resin (Piocerain (registered trademark) manufactured by Sekisui Plastics Co., Ltd.). An example of the second foam layer 12 is a non-crosslinked highly foamed polyethylene resin having a foaming ratio of 15 times. The material constituting the second foamed layer 12 of the present embodiment is a polyethylene resin foam (Lithron (registered trademark) board, manufactured by Sekisui Plastics Co., Ltd.). The physical property value of the first foam layer 11 and the physical property value of the second foam layer 12 are different from each other. For example, when the first foam layer 11 and the second foam layer 12 are made of the materials described above, the compressive stress of the first foam layer 11 is the second having the same expansion ratio as that of the first foam layer 11. It is higher than the compressive stress of the foam layer 12, and the restoring force of the first foam layer 11 is lower than the restoring force of the second foam layer 12 having the same expansion ratio as that of the first foam layer 11.

  In addition, the shape of the buffer body 10 can be arbitrarily changed. For example, the shape of the buffer 10 may be a cylinder. Moreover, the material of the 1st foamed layer 11 and the 2nd foamed layer 12, foaming magnification, thickness T1, T2 can be changed arbitrarily. For example, the thickness T1 of the first foam layer 11 may be equal to or less than the thickness T2 of the second foam layer 12.

  As shown in FIG. 5, the exterior body 20 includes a sheet 23 including an inner surface portion 21 and an outer surface portion 22. The sheet 23 is a sheet excellent in strength and water resistance. For example, the sheet 23 is made of tarpaulin formed by sandwiching a sheet made of resin fibers such as polyester with a film made of a highly waterproof thermoplastic resin such as vinyl chloride. is there. The thickness of the sheet 23 is preferably 0.25 mm or more in order to obtain sufficient strength and water resistance. The sheet 23 includes a rectangular outer surface portion 22 constituting the outer surface portion 22 of the exterior body 20, a pair of first side portions 24 extending from a pair of short sides in the outer surface portion 22, and a pair of long sides in the outer surface portion 22. It is comprised from a pair of 2nd side part 25 extended. The pair of first side portions 24 has a line symmetry shape with respect to the center line L <b> 1 of the sheet 23, and the pair of second side portions 25 has a line symmetry shape with respect to the center line L <b> 2 of the sheet 23. The center line L1 of the sheet 23 is a line segment that extends in the direction along the short side of the sheet 23 and passes through the central part of the pair of long sides of the sheet 23. The center line L2 of the sheet 23 is a line segment that extends in the direction along the long side of the sheet 23 and passes through the central portion of the pair of short sides. In the following description, the direction along the long side of the sheet 23 is referred to as “lateral direction X”, and the direction along the short side of the sheet 23 is referred to as “vertical direction Y”.

  Three passage sheets 26 are fixed to the inner surface 22 a of the outer surface portion 22. The passage sheet 26 according to the present embodiment is sewn to the inner surface 22 a of the outer surface portion 22. The passage sheet 26 is made of tarpaulin, for example. The three passage sheets 26 are arranged at intervals in the vertical direction Y. The passage sheet 26 has a strip shape extending along the extending direction of the string body 30. The passage sheet 26 of the present embodiment has a length over the entire outer surface portion 22 in the lateral direction X. The passage sheet 26 defines a passage 26 a through which the string body 30 (see FIG. 6) passes between the shock absorber 10 and the outer surface portion 22. In addition, the material which comprises the sheet | seat 26 for passages can be changed arbitrarily. For example, the material constituting the passage sheet 26 may be different from the material constituting the sheet 23. Moreover, the fixing method to the inner surface 22a of the outer surface part 22 of the channel | path sheet | seat 26 can be changed arbitrarily. For example, the passage sheet 26 may be fixed to the inner surface 22a of the outer surface portion 22 with an adhesive.

  A proximal end laminated portion 24 a is provided at the proximal end of the first side portion 24, and a distal end laminated portion 24 c is provided at the distal end of the first side portion 24. The proximal end laminated portion 24 a and the distal end laminated portion 24 c are configured by laminating a belt-like sheet on the inner surface of the first side portion 24. The sheet | seat which comprises the base end laminated | stacked part 24a and the front-end | tip laminated | stacked part 24c is a product made from tarpaulin, for example, and is sewn on the inner surface of the 1st side part 24. FIG. Thus, by laminating | stacking the base end laminated | stacked part 24a on the 1st side part 24, the part to which force is applied by the string 30 in the 1st side part 24 is reinforced. As a result, the sheet 23 can be prevented from being broken due to the cord body 30 biting into the sheet 23.

  A string insertion hole 24b is located in each of the portions corresponding to the three passage sheets 26 in the base end laminated portion 24a. The string insertion hole 24b is a long hole whose longitudinal direction is the longitudinal direction. Three insertion holes 24d are located in the tip stack portion 24c. The three insertion holes 24d are located at intervals in the vertical direction Y. The positions of the three insertion holes 24d are the same as the three string insertion holes 24b in the vertical direction Y. The positions of the three insertion holes 24d are arbitrary setting items. For example, the positions of the three insertion holes 24d may be different from the three string body insertion holes 24b in the vertical direction Y.

  A hook-and-loop fastener portion 24e is provided at both ends in the longitudinal direction Y on the inner surface of the first side portion 24. The hook-and-loop fastener portion 24e is located closer to the tip laminated portion 24c. The hook-and-loop fastener portion 24e has a strip shape extending in the lateral direction X.

  At both ends in the longitudinal direction Y of the first side portion 24, blade portions 24 f are provided so as to protrude in the longitudinal direction Y from the side surfaces in the longitudinal direction Y of the first side portion 24. The blade portion 24f is located closer to the proximal end laminated portion 24a. The pair of blade portions 24 f have a line-symmetric shape with respect to the center line L <b> 2 of the sheet 23. The blade portion 24f has a trapezoidal shape. The length of the long side of the bottom side of the blade portion 24f is equal to the thickness (T1 + T2) of the buffer body 10.

  A tip stacking portion 25 a is provided at the tip of the second side portion 25. The leading end laminated portion 25 a is configured by laminating a belt-like sheet on the second side portion 25. The sheet | seat which comprises the front-end | tip lamination | stacking part 25a is a product made from tarpaulin, for example, and is sewn on the inner surface of the 2nd side part 25. FIG. Three insertion holes 25b are located in the front end laminated portion 25a with a gap in the lateral direction X.

  At both end portions in the lateral direction X of the second side portion 25, blade portions 25c are provided so as to protrude in the lateral direction X from the side surfaces in the lateral direction X of the second side portion 25. The blade portion 25 c is located on the proximal end side of the second side portion 25. For this reason, the blade portion 25 c is adjacent to the blade portion 24 f of the first side portion 24. The pair of blade portions 25 c have a line-symmetric shape with respect to the center line L <b> 1 of the sheet 23. The blade part 25c has the same shape as the blade part 24f. The oblique sides of the blade portions 24f and 25c adjacent to each other are sewn together.

  As shown in FIG. 6, hook-and-loop fastener portions 25 d are provided at both ends in the lateral direction X on the outer surface of the second side portion 25. The hook-and-loop fastener portion 25 d is located on the distal end side of the second side portion 25. The hook-and-loop fastener portion 25d is formed in a strip shape extending in the lateral direction X.

  As shown in FIG. 6, the string members 30 are respectively passed through the inner surface 22 a side of the passage sheet 26 located on the inner surface 22 a (see FIG. 5) of the outer surface portion 22. The string 30 is exposed to the outside of the exterior body 20 through the string insertion holes 24b on both sides. The string body 30 of the present embodiment is passed through the one string body insertion hole 24b, the passage 26a of the passage sheet 26, and the other string body insertion hole 24b in this order, and then folded back to the other string body insertion hole 24b. The passage 26a of the passage sheet 26 and the one string member insertion hole 24b are passed through in this order. For this reason, the string body 30 exposed from the one string body insertion hole 24b to the outside of the exterior body 20 has both ends of the string body 30, and is exposed to the outside of the exterior body 20 from the other string body insertion hole 24b. The string 30 is formed in an annular shape. In the present embodiment, the first attachment portion 31 of the string body 30 is a portion exposed to the outside of the exterior body 20 from one string body insertion hole 24b, and the second attachment portion 32 of the string body 30 is the other string. It is a part exposed to the exterior of the exterior body 20 from the body insertion hole 24b.

The exterior body 20 having such a configuration covers the buffer body 10 as follows.
As shown in FIG. 7, in the state where the buffer body 10 is placed on the inner surface 22 a of the outer surface portion 22 of the exterior body 20, the second side portion 25 is valleyd around the inner edge along the lateral direction X in the second side portion 25. It is folded. Accordingly, the second side portion 25 covers the side surface in the lateral direction X of the buffer body 10.

  Next, the second side portion 25 is valley-folded around the valley fold line V <b> 2 along the horizontal direction X at the center of the second side portion 25. Thereby, as shown in FIG. 8, the 2nd side part 25 covers the inner surface which is a surface on the opposite side to the surface by the side of the 2nd foam layer 12 in the 1st foam layer 11. As shown in FIG. For this reason, the part which covers the inner surface of the 1st foam layer 11 in the 2nd side part 25 comprises the inner surface part 21 of the exterior body 20. FIG. That is, the portion on the tip side of the second side portion 25 with respect to the valley fold line V <b> 2 (see FIG. 7) constitutes the inner surface portion 21. At this time, the hook-and-loop fastener portion 25 d of the second side portion 25 is located on the inner surface portion 21. And the connection body 40 is passed through the insertion hole 25b corresponding to the vertical direction Y of the insertion holes 25b of the pair of second side portions 25, and both ends of the connection body 40 are connected to each other.

  Next, the first side portion 24 is folded around the inner edge along the longitudinal direction Y in the first side portion 24. Accordingly, the first side portion 24 covers the side surface in the vertical direction Y of the shock absorber 10. At this time, the blade portion 24f is bent so as to overlap with the blade portion 25c adjacent to the blade portion 24f. Accordingly, the blade portions 24f and 25c are located between the side surface in the vertical direction Y of the buffer body 10 and the first side portion 24 and cover a part of the side surface in the vertical direction Y of the buffer body 10.

  Next, the first side portion 24 is folded around the valley fold line V <b> 1 along the longitudinal direction Y at the center of the first side portion 24. Thereby, as shown in FIG. 9, the first side portion 24 covers the inner surface of the buffer body 10. For this reason, the part which covers the inner surface of the buffer 10 in the 1st side part 24 comprises the inner surface part 21 of the exterior body 20. FIG. That is, the front side portion of the first side portion 24 with respect to the valley fold line V1 (see FIG. 8) constitutes the inner surface portion 21. The first side portion 24 constituting the inner surface portion 21 covers the second side portion 25 constituting the inner surface portion 21. At this time, the hook-and-loop fastener portion 24e of the first side portion 24 is disposed at a position corresponding to the hook-and-loop fastener portion 25d of the second side portion 25 in the inner surface portion 21, and is joined to the hook-and-loop fastener portion 25d. Thereby, the inner surface portion 21 in the first side portion 24 and the inner surface portion 21 in the second side portion 25 are fastened. And the connection body 40 is passed through the insertion hole 24d corresponding to the lateral direction X of the insertion holes 24d of the pair of first side portions 24, and both ends of the connection body 40 are connected to each other. Thus, the exterior body 20 covers the buffer body 10 without detaching from the buffer body 10.

Next, the effect | action of the fender 1 mentioned above is demonstrated.
As shown in FIG. 10, the string body 30 is passed between the outer surface portion 22 of the exterior body 20 and the buffer body 10. For this reason, when a structure (for example, another ship or a structure constituting a berth) collides with the outer surface portion 22 from the outside of the fender 1, the structure collides with the outer surface portion 22 of the exterior body 20. Therefore, it is avoided that the structure directly collides with the string body 30.

  And the 2nd attaching part 32 of the string 30 is attached so that the outer peripheral surface of the pole 140 of the hull 110 may be followed. The first attachment portion 31 including both ends of the string body 30 has one end of the string body 30 wound from above the bow rail 130 and the other end of the string body 30 wound from below the bow rail 130. The body 30 is attached to the bow rail 130 by connecting both ends thereof. By attaching the string body 30 to the hull 110 in this way, a force that the string body 30 pushes the shock absorber 10 toward the hull 110 is applied to the shock absorber 10, so that the fender 1 is in close contact with the hull 110. . Therefore, the formation of a gap between the inner surface portion 21 of the exterior body 20 and the hull 110 in the fender 1 is suppressed. As a result, seawater is prevented from entering between the hull 110 and the inner surface portion 21 when the wave collides with the hull 110, so that the hull 110 is stabilized.

As described above, according to the embodiment, the following effects can be obtained.
(1) Since the string body 30 is not exposed on the outer surface side of the outer surface portion 22 of the exterior body 20, even if the fender 1 collides with the structure, the string body 30 may be damaged or cut. Lower. Therefore, it is possible to suppress the shock absorber 10 from dropping from the hull 110.

  (2) Since the string body 30 is passed through the passage 26a of the passage sheet 26 provided on the inner surface 22a of the outer surface portion 22, the string body 30 and the buffer body 10 are prevented from contacting each other. Accordingly, even when an impact is applied to the outer surface portion 22 from the outside of the fender 1 or when the string body 30 is attached to the hull 110, even if the string body 30 is pushed toward the buffer body 10, Biting in is suppressed. As a result, the buffer body 10 is suppressed from being damaged by the string body 30.

  Further, when seawater or rainwater flows in from the upper end of the fender 1, seawater or rainwater may enter the exterior body 20 from the string body insertion hole 24 b on the upper end side of the exterior body 20. However, seawater or rainwater entering from the string body insertion hole 24b on the upper end side passes between the passage sheet 26 and the inner surface 22a of the outer surface part 22 (passage 26a), and from the string body insertion hole 24b on the lower end side. It flows downward from the fender 1. Thus, even if seawater or rainwater flows in from the upper end portion of the fender 1, it is possible to prevent seawater or rainwater from entering the fender 1.

  In addition, since the string body 30 is movable in the extending direction in the passage 26a, the lengths of the first attachment part 31 and the second attachment part 32 of the string body 30 can be adjusted. Therefore, the arrangement position of the fender 1 with respect to the hull 110 can be adjusted.

  (3) Since the exterior body 20 is made of tarpaulin, the exterior body 20 is unlikely to be damaged even when a structure collides. Therefore, seawater and rainwater are caused to pass through the exterior body 20 due to damage of the exterior body 20. Can be prevented from entering.

  (4) Since the surface fastener portions 24e and 25d provided on the inner surface portion 21 of the exterior body 20 are joined to each other, the first side portion 24 and the second side portion 25 constituting the inner surface portion 21 are peeled off from each other. Is suppressed. Therefore, it becomes difficult for seawater and rainwater to enter from between the first side portion 24 and the second side portion 25 constituting the inner surface portion 21.

  (5) The compression restoring force of the first foaming layer 11 is higher than the compressive stress of the second foaming layer 12, and the restoring force of the first foaming layer 11 is lower than the restoring force of the second foaming layer 12. The shock absorber 10 is composed of two different foam layers. For this reason, it is possible to achieve both of buffering the impact applied toward the hull 110 and restoring the distortion of the buffer 10 caused by the impact.

  (6) When the first foam layer 11 having a higher compressive stress receives an impact from the outside, the first foam layer 11 receives the impact on the entire surface of the first foam layer 11 that receives the impact. On the other hand, when the second foam layer 12 having a lower compressive stress receives an impact from the outside, the second foam layer 12 receives an impact on a part of the impact surface of the second foam layer 12. For this reason, when the 1st foaming layer 11 receives an impact from the outside, a part of 2nd foaming layer 12 deform | transforms with the force in which the 1st foaming layer 11 presses the 2nd foaming layer 12. FIG. Thereby, there exists a possibility that the 1st foam layer 11 and the 2nd foam layer 12 may peel.

  In that respect, in this embodiment, since the 1st foam layer 11 is located in the ship body 110 side rather than the 2nd foam layer 12, it is suppressed that the 1st foam layer 11 receives an impact directly from the outside. That is, when the fender 1 receives an impact from the outside, the second foam layer 12 receives the impact, and the second foam layer 12 presses the first foam layer 11. As a result, the force applied from the second foam layer 12 to the first foam layer 11 is received by the entire surface that receives the force of the first foam layer 11, so that the first foam layer 11 and the second foam layer 12 are peeled off. Is suppressed.

  (7) Since the four corners of the shock absorber 10 are covered with the blade portions 24f of the pair of first side portions 24 and the blade portions 25c of the pair of second side portions 25, the first side portion 24 and the second side portion 25 that are adjacent to each other. It is suppressed that seawater and rainwater enter the buffer body 10 from the boundary portion.
