It is a front view which shows the state of being inserted into a member.

With reference to each figure, the fender structure 1A of this example is installed on the upright surface S of the quay G, and the fender 2 and the left and right side surface portions of the fender 2 are respectively. It includes a pair of vertical support members 3 that are detachably supported, and a horizontal guide member 4 that holds each of the pair of vertical support members 3 so as to be movable in the horizontal direction along the upright surface S.

The fender 2 has a substantially V-shaped cross section in the horizontal direction, and has an abutting portion 2a on the surface side that receives a load when coming alongside, and a bearing portion 2b that faces the upright surface S and supports the load. A flange portion 2c is formed on the support portion 2b so as to project outward on the left and right sides. The bearing surface 2d of the bearing portion 2b facing the upright surface S abuts on the horizontal guide member 4. In the horizontal guide member 4, the region where the vertical support member 3 comes into contact is defined as the contact region 5.

The vertical support member 3 is composed of a pair of a member 3A on the left side and a member 3B on the right side, and holds the left and right side portions of the fender 2 detachably. In this embodiment, the left and right vertical support members 3A and 3B have a U-shaped horizontal cross section, and the fender 2 is supported by inserting the flange portion 2c between them from above. ing. As means for locking the fender 2 to the vertical support member 3, a structure in which a stopper is provided on the lower end side of the vertical support member 3 in contact with the lower end surface of the fender, or the upper end side of the fender 2. A structure or the like in which a stopper that engages with the upper end surface of the vertical support member 3 is provided is conceivable.

The horizontal guide member 4 is fixed on the upright surface S and holds the vertical support member 3 so as to be movable in the horizontal direction. The horizontal guide member 4 of this embodiment includes a member 4A arranged in the upper left region of the fender 2 and a member 4B arranged in the upper right region, and a lower left side, based on the mounting position of the fender 2. It is composed of a member 4C arranged in the region and a member 4D arranged in the lower right region. The left horizontal guide members 4A and 4C hold the left vertical support member 3A, and the right horizontal guide members 4B and 4D hold the right vertical support member 3B.

Although not shown, a holding means for holding the vertical support member 3 at a predetermined position or an arbitrary position with respect to the horizontal guide member 4 is provided.

The fender structure 1A configured as described above can be easily attached by inserting the fender 2 between the pair of left and right vertical support members 3 from above, and conversely, the fender 2 Can be easily removed by pulling it upward from the vertical support member 3, so that the fender 2 can be easily attached and detached. Further, since the vertical support member 3 is held so as to be horizontally movable by the horizontal guide member 4, the horizontal dimension of the fender 2 to be attached is adjusted by adjusting the distance between the left and right vertical support members 3A and 3B. Can be adjusted to.

In the fender structure 1A configured in this way, it is easy to change the fender 2 to one having different horizontal and vertical dimensions. Specifically, when the relatively narrow first fender 2α as shown in FIGS. 1A and 1B is used for the side of a relatively small ship, it is temporarily relatively large. Suppose that it becomes necessary to bring the ship alongside. In this case, as shown in FIG. 3, after the first fender 2α is pulled out from between the vertical support members 3, the left and right vertical support members 3A and 3B are horizontally moved along the horizontal guide member 4 to both of them. After increasing the interval between the two, as shown in FIG. 4, a second fender 2β having a relatively large horizontal and vertical dimension is inserted between them. This makes it possible to change the configuration of the fender structure 1A so that it can correspond to the side of a large ship in a short time. Further, since the left and right vertical support members 3A and 3B can be moved in the horizontal direction, the position of the center line should not be changed when the fenders 2α and 2β having different horizontal and vertical dimensions are replaced. be able to. Alternatively, the position of the center line can be shifted if necessary.

In this way, the fender structure 1A can be easily changed to fenders with different horizontal and vertical dimensions in a short time, so that ships of different sizes frequently come alongside quays and ships. It has the advantage of being able to prepare the optimum fender structure for various sizes of ships in canals and the like.

By the way, the vertical support member 3 is defined to have a range in which it can move horizontally with respect to the horizontal guide member 4. Therefore, a lower limit value L1 and an upper limit value L2 are set for the distance between the left and right vertical support members 3A and 3B. .. Within the range of the upper limit value and the lower limit value, it is possible to attach a fender of any horizontal dimension.

In this embodiment, as shown in FIG. 1A (B), the horizontal guide member 4 has a contact region 5 that abuts the support surface 2d of the support portion 2b of the fender 2 on its surface. When the distance between the pair of vertical support members 3A and 3B is the lower limit value L1, the horizontal length dimension M of the contact region 5 located inside the vertical support members 3A and 3B is the bearing of the fender 2. It is set to be equal to or larger than the horizontal dimension D of the surface 2d. As a result, even if the distance between the pair of vertical support members 3A and 3B is set to the lower limit value L1, the support portion 2b of the fender 2 can be reliably brought into contact with the abutment region 5. Even when 2 is replaced with the one with the smallest horizontal and vertical dimensions that can be supported, stability with respect to the side can be surely obtained.

Further, in this embodiment, the upper limit value L2 is in the range of 1.5 to 2 times the lower limit value L1 with respect to the lower limit value L1 and the upper limit value L2 of the horizontal spacing of the vertical support members 3A and 3B. Is set to be. As a result, the upper limit value L2 of the horizontal dimension of the fender 2 supported between the vertical support members 3A and 3B is defined, so that the strength design of the structure such as the vertical support member 3 and the horizontal guide member 4 is easy. It becomes. If the upper limit value L2 is allowed to exceed twice the lower limit value L1, the maximum size of the fender to be used becomes larger than that of the minimum size and the weight increases. Therefore, a structure supporting this. The strength of the object must be increased, which may increase the cost. On the contrary, if the upper limit value L2 is less than 1.5 times the lower limit value L1, there is a possibility that the advantage of replacing the fender is hardly obtained. For this reason, the ratio of the upper limit value L2 to the lower limit value L1 is preferably set in the range of 1.5 to 2 times.
