Japanese Patent Laid-Open No. 7-292620

  By the way, in the case of the configuration in which the fender is attached to the pier frame with bolts as in the former configuration, the bolting work is required when attaching the fender, so the work at the time of the installation work Not only is the performance not good, but if the fender is deteriorated, cracks may occur from the periphery of the portion fixed by the bolt. Moreover, since the bolt is exposed or the joint with the cover member is visible on the contact side of the ship in the fender, the appearance of the jetty after the fender is attached is impaired.

  Also, in the case of the configuration in which the fender is slid with respect to the groove provided in the pier frame as in the latter configuration, the fender is surely fitted to the frame. Then, the slip between the fender and the frame is deteriorated and the workability of the fender is deteriorated. On the other hand, when the slip between the fender and the frame is improved, the fender is The fitting with the frame becomes loose. Furthermore, when it is necessary to partially replace the fender, it is necessary to slide the fenders other than the part to be replaced together and remove them once, so the workability during maintenance work is also poor. Problems arise.

  The present invention has been made in view of such various points, and an object of the present invention is to prevent the occurrence of damage to the fender caused by the mounting structure in the fender attached to the side surface of the pier body. It is possible to obtain a configuration that can improve the mounting workability and the maintenance workability without impairing the appearance.

  In order to achieve the above object, in the fender according to the present invention, a plurality of protrusions projecting from a body portion having a cavity inside and engaging with a peripheral portion of an opening formed on a side surface of a pier body. By providing a meat stealing part between them and facilitating deformation so that the protruding parts approach each other, a fender can be easily attached to the pier body.

  Specifically, the invention of claim 1 is directed to a fender that is attached to a side surface of a jetty body. And a body part which has a cavity inside and absorbs the impact of the ship in contact, and a peripheral part of the opening part which is provided on the opposite side to the contact side of the ship in the body part and is formed in the pier body A fitting portion having a plurality of protruding portions engaged with each other, and between the protruding portions in the fitting portion, a meat stealing portion that can be elastically deformed so that the protruding portions approach each other It shall be formed.

  With this configuration, even in the configuration in which the fitting portion is provided in the main body portion having a hollow inside and having low rigidity, the fitting portion can be easily attached to the side surface of the jetty main body. That is, the plurality of protrusions of the fitting portion that engage with the peripheral portion of the opening formed in the pier body are brought closer to each other by the meat stealing portion formed between the protrusions. Since it is deformable, the protrusion of the fitting portion can be easily inserted into the opening. And after inserting the said protrusion part in an opening part, this protrusion part engages with the peripheral part of an opening part, and a fender is attached and fixed to a pier main body.

  As described above, a configuration in which a fender is fixed to a bolt as in the past or a fender by adopting a configuration in which the protruding portion of the fitting portion can be easily inserted into the opening of the pier body. Compared with the structure etc. which slide is moved in a groove | channel etc., attachment work becomes easy and can improve workability | operativity.

  Further, by adopting the above-described configuration, the fender can be improved in durability without cracking the fender from around the bolt as in the case where the fender is fixed with a bolt.

  Furthermore, even when a part of the fender is replaced, it is not necessary to slide the fender other than the corresponding part, so that the workability of the maintenance work temple can be improved.

  In the above-described configuration, the protruding portion is formed integrally with the main body portion, and the meat stealing portion is formed on the outer surface of the main body portion opposite to the contact side of the ship ( Second invention).

  Accordingly, the plurality of protrusions integrally formed in the soft main body portion having a cavity inside can be easily deformed so as to approach each other by the meat stealing portion, and the protrusion portions can be formed in the opening of the jetty main body. Can be easily inserted into. Therefore, the configuration of the first invention can be realized with a simple configuration.

  In addition, a partition wall is provided inside the main body portion so as to extend in the contact direction of the ship and divide the cavity inside the main body portion into a plurality of parts, and the fitting portion is seen from the contact side of the ship. It is preferable to be provided at a position that does not overlap the partition wall (third invention).

  The part in which the partition wall is provided in the main body so as to extend in the contact direction of the ship has higher rigidity in the contact direction of the ship than the other parts. Therefore, if the fitting part is provided in the part with high rigidity, it is not so difficult to engage the protruding part of the fitting part in the opening of the pier body. In the configuration in which the fitting portion is provided at a position that does not overlap the partition wall when viewed from the contact side, it is very difficult to fit the fitting portion formed on the main body portion having low rigidity into the opening portion. Therefore, in the case of the configuration as described above, the configuration of the first and second inventions allows the fitting portion of the fender to be easily fitted into the opening, and the fender It is possible to reliably improve the workability when attaching to the pier body.

  Moreover, it is preferable that the said meat stealing part is formed in the intermediate position of the said protrusion part and a protrusion part (4th invention). As a result, the plurality of protrusions can be more easily deformed so as to approach each other, so that the protrusions can be more easily inserted into the opening of the pier body, and the fenders can be inserted into the pier body. Installation workability can be improved.

  According to the first invention, between the plurality of protrusions protruding from the main body having a cavity inside and engaged with the peripheral portion of the opening formed on the side surface of the jetty main body, Since the deformable meat stealing portion is provided so that the protruding portions approach each other, it is possible to improve the workability of attaching the protruding portion to the pier body. Further, the durability can be improved as compared with the conventional bolt-fixed structure, and the workability during the maintenance work can be improved as compared with the structure in which the fender is slid relative to the mounting member.

  According to the second invention, the protruding portion is formed integrally with the main body portion, and the meat stealing portion is formed on the outer surface of the main body portion on the opposite side to the ship contact side. The configuration of the first invention can be realized with a simple configuration.

  According to a third aspect of the present invention, the main body is provided with a partition wall that extends in a ship contact direction and divides a cavity inside the main body into a plurality of parts. The configuration of the first and second aspects of the invention is different from the configuration in which the fitting portion is provided in the portion having low rigidity as described above. If applied, it is more effective.

  Further, according to the fourth invention, since the meat stealing portion is provided at an intermediate position between the protruding portion and the protruding portion, the protruding portions can be brought closer to each other, and the fender is attached. The workability of attaching to the member can be further improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature and is not intended to limit the present invention, its application, or its use.

−Floating pier configuration−
FIG. 1 shows a schematic configuration of a floating jetty 1 to which a fender 20 according to an embodiment of the present invention is applied. The floating pier 1 is used as a mooring facility for mooring a small ship, for example, and includes a pier main body 2 (pier main body) that constitutes a person passage, a mooring portion of a ship, and the pier main body. And a float 3 for floating 2 on the water.

  The pier body 2 is formed on the upper surface so as to constitute a passage through which a person can pass. Specifically, the pier body 2 includes a frame 11 formed by combining metal cylindrical members, and a deck 12 supported by the frame 11. This frame 11 is formed by arranging a plurality of beam members 14, 14,... Between two rectangular tube members 13, 13 arranged in parallel. It is configured to have a strength capable of supporting the weight of a moving person or object.

  Further, the beam member 14 is positioned on the rectangular tube member 13 at a position below the upper surface of the rectangular tube member 13 by the thickness of the deck 12 so that the deck 12 can be disposed on the beam member 14. It is connected. Thereby, the upper surface of the said frame 11 and the upper surface of the said deck 12 can be made substantially flush, and the improvement of the external appearance of the floating jetty 1 can be aimed at.

  Further, as will be described in detail later, the side surface of the frame 11 on the outer side in the width direction of the pier main body 2 absorbs an impact when a ship collides with the pier main body 2 during mooring or mooring. A fender 20 is provided. By providing the fender 20, energy when the ship collides can be absorbed by the fender 20, and the pier body 2 can be prevented from being damaged.

  The deck 12 constitutes the passage through which a person can pass, and is disposed below the flat plate member 15 and a plurality of wooden flat plate members 15, 15,. A plurality of reinforcing members 16, 16,... Extending in parallel are provided. That is, a plurality of the flat plate members 15 are attached and fixed to the reinforcing member 16 in a state of being arranged in the short direction, and the reinforcing member 16 is placed on the beam member 14 of the frame 11. Then, it is laid on the frame 11.

  If the end of another frame 17 is connected to the side surface of the rectangular tube member 13 of the frame 11 and another deck 18 is disposed on the frame 17, as shown in FIG. A floating pier having a letter-shaped passage can be formed.

  The float portion 3 is formed in a bag shape so that gas can be stored therein, and is attached to the lower side of the frame 11 of the pier body portion 2. By disposing the float part 3 below the pier body 2, the pier body 2 can be reliably floated on the water surface, and the ship can be moored on the pier body 2.

-Fender-
Of the side surfaces of the rectangular tube member 13 constituting the pier body portion 2 of the floating pier 1, grooves 13a (openings) extending in the longitudinal direction are formed on the side surfaces at both ends in the width direction of the pier body portion 2. Thus, the fender 20 is fitted into the groove 13a.

  Specifically, as shown in FIG. 2, a groove 13a is provided on the upper side of the side surface of the rectangular tube member 13 so as to extend in the longitudinal direction of the rectangular tube member 13, and the inner peripheral edge of the groove 13a. The fitting part 22 of the fender 20 is fitted to the (peripheral part).

  More specifically, the fender 20 is made of an elastic material (for example, rubber hardness Shore A having a hardness of about 30 to 95) such as rubber or a polymer elastomer (for example, polyvinyl chloride, polyurethane, polyolefin, etc.). And a fitting portion having a main body portion 21 having a substantially D-shaped cross section and two protrusions 23 and 23 (protruding portions) integrally formed on the main body portion 21 so as to protrude from the plane side of the main body portion 21. 22.

  The body portion 21 of the fender 20 has a cavity formed therein so as to have a substantially D-shaped cross section, and a partition wall 21b is integrally formed therein so as to divide the cavity into two. Yes. The fender 20 is attached to the square tube member 13 via the fitting portion 22 provided on the plane side of the main body 21 so that the curved surface side of the main body 21 is in contact with the ship. It is attached. That is, the partition wall 21b is provided in the main body portion 21 so as to extend in a direction in which an impact is transmitted by contact with a ship (hereinafter also referred to as a contact direction). The upper and lower cavities 21a and 21a are partitioned by the partition wall 21b.

  The fitting portion 22 is provided at an upper portion of the main body portion 21 of the fender 20 so as not to overlap the partition wall 21b when viewed from the ship contact side. Since the position that does not overlap with the partition wall 21b when viewed from the ship contact side is lower in rigidity in the ship contact direction than the position that overlaps with the partition wall 21b, the fitting portion 22 is provided at such a position. In the configuration, the fitting portion 22 is difficult to fit into the groove 13a of the square tube member 13 even if the main body portion 21 is pushed. Therefore, as will be described in detail later, in the present invention, the fitting portion 22 is devised so that the fitting portion 22 can be easily fitted into the groove 13a.

  The fitting portion 22 includes two protrusions 23 and 23 that are formed so as to be separated from each other toward the protruding end. Thus, by forming the protrusions 23 and 23 so as to be separated from each other toward the tip, the protrusions 23 and 23 are inserted into the grooves 13a of the rectangular tube member 13, The protrusions 23 and 23 can be engaged with the inner peripheral edge (peripheral part) of the groove 13 a by the elastic restoring force of the protrusions 23 and 23. In addition, a flange portion 23 a that bulges to the opposite side of the other ridge portion 23 is formed on the distal end side of each ridge portion 23. Thereby, the said protrusion 23 is more reliably engaged with the groove | channel 13a of the said square cylinder member 13 by the said collar part 23a.

  In the fitting part 22, the longitudinal direction of the fender 20 (the paper surface of FIG. 2) is provided on the outer surface of the main body part 21 between the protrusion parts 23, 23 on the plane side (attachment side to the square tube member 13). A groove-shaped meat stealing portion 22a extending in the direction) is provided. The meat stealing portion 22 a is provided in the middle of the two protrusions 23, 23 and has a depth that is approximately half the thickness of the main body 21. Accordingly, the protrusions 23 and 23 are likely to be elastically deformed in a direction approaching each other. Therefore, when the protrusions 23 and 23 are inserted into the grooves 13a of the rectangular tube member 13, the protrusions 23 and 23 are formed. 23 and 23 can be easily deformed and brought close to each other, and the insertion work of the ridges 23 and 23 into the groove 13a is facilitated. Therefore, by providing the meat stealing portion 22a as described above, it is possible to improve workability when attaching the protrusions 23 and 23 to the groove 13a of the rectangular tube member 13.

  Further, the meat stealing portion 22a is formed so that the bottom portion is substantially circular in a sectional view. Thereby, when a deformation | transformation arises in the said meat stealing part 22a, stress concentration arises in the bottom part of this meat stealing part 22a, and it can prevent that the fender 20 is damaged by this stress concentration.

-Effect of the embodiment-
As described above, according to this embodiment, in the fender 20 attached to the square tube member 13 constituting the frame 11 of the floating pier 1, the fitting portion 22 engaged with the groove 13 a of the square tube member 13 is provided. A groove-shaped meat stealing portion extending in the longitudinal direction of the fender 20 on the surface (outer surface) on the plane side (mounting side) of the main body 21 having a substantially D-shaped cross section between the protrusions 23 and 23. Since 22a is provided, when the ridges 23 and 23 are inserted into the groove 13a, the ridges 23 and 23 can be easily deformed so that the ridges 23 and 23 approach each other, The insertion work of the protrusions 23 and 23 into the groove 13a can be easily performed. Therefore, the workability of attaching the fender 20 to the frame 11 can be improved.

  In particular, in the configuration in which the fitting portion 22 is provided at a position that does not overlap with the partition wall 21b of the main body portion 21 when viewed from the ship contact side as in the above-described embodiment, the main body portion corresponding to the fitting portion 22 is provided. 21 has low rigidity in the contact direction of the ship, even if the main body 21 is pressed when the engaging portion 22 is engaged with the groove 13a of the square tube member 13, the force is not easily transmitted to the engaging portion. Although it is very difficult to engage the portion 22 with the groove 13a, the engagement portion 22 can be easily engaged with the groove 13a by providing the meat stealing portion 22a as described above. Further, when the main body portion 21 is made of a soft material (for example, an elastic material such as rubber or elastomer) and is thicker than a resin molded product that generates a large spring force at the time of elastic deformation, the engagement portion Although it becomes more difficult to engage the groove 22 with the groove 13a, the engaging portion 22 can be easily engaged with the groove 13a by adopting the configuration as described above. That is, in the case of the soft and thick main body 21, the above-described configuration is more effective.

  Moreover, with the above-described configuration, the fender 20 can be attached from the front to the frame 11 of the floating pier 1 without sliding the fender as in the prior art. Therefore, when replacing the fender 20, only the replacement part can be removed and a new fender 20 can be attached, and workability during maintenance work can be improved.

  Further, when the protrusions 23 and 23 are deformed so as to approach each other as described above by making the bottom portion of the meat stealing portion 22a into a substantially circular shape in a cross-sectional view, the deformation occurring in the meat stealing portion 22a. Therefore, stress concentration can be prevented from occurring at the bottom of the meat stealing portion 22a, and the fender 20 can be prevented from being damaged by the stress concentration.
