来る。FIG. 8 shows a fourth embodiment of the fender according to the present invention, in which a fender body 2 provided with a base 5 at the bottom is fixed to a cylinder having a fixed height using an elastic material sheet 15. The air valve 8 is provided as a cylindrical body 18 having an airtight chamber structure in which the upper space is covered with a roof 7 or a sheet 16 made of rubber or the like.
And a plurality of flexible tension members 19 such as wire ropes are arranged at regular intervals around the circumference of the cylindrical body 18 so as to be fixed vertically.
The length of the body 9 is substantially the same along the maximum swelling diameter C of the body sheet 15 at the time of the maximum compression B of the cylindrical body 18 and is embedded in the body sheet 15 or externally mounted and molded. By applying an initial internal pressure to the body 18, the set stopper 11 is set.
When the tension is extended to the length, a recess E is formed in the body longitudinal direction in which the plurality of tension members 19 are arranged, and the cross section of the body 18 is formed in a chrysanthemum shape. Accordingly, by reinforcing the body 18 with the tension member 19 in this manner, the main body 18 can be provided in a pressure-resistant structure, and the initial internal pressure can be set high. At the same time, the body 18 is compressed by receiving external energy due to berthing. When the height D of the body 18 is compressed, the tension member 19 forming the recess E expands as the height D of the body 18 is compressed. The initial internal pressure is maintained without a large change in the volume in the body 18 up to the compression middle point of the body height D, which is circular, and further compression is applied from the middle point to the maximum compression B. When
Since the length of the tension member 19 is set to be substantially the same as the maximum bulging diameter C of the elastic material sheet 15, the tension member 19 is formed so as to be able to receive an internal pressure that increases with sufficient pressure resistance. Therefore, by setting the initial internal pressure high, it is possible to absorb extremely large energy, and at the same time, it is possible to suppress the rate of change of the initial internal pressure and the internal pressure at the time of intermediate compression and maximum compression at a low level. It can be very low. The body 18 is provided with an impact plate 6 at an upper part and an air valve 8 at a lower part. Further, the fender of the present invention may use a bag body 9 for filling air therein.

る。FIG. 11 relates to auxiliary means for improving the characteristics attached to the fixed type pneumatic fender of the present invention. An air chamber 21 which is not deformed by air pressure is provided in the body 2 of the main body. The air chamber 21 is provided with a small vent hole 21a directly communicating with the inside of the main body 2 to allow the air to move freely. When the air pressure inside the main body 2 suddenly increases due to external energy, the increased air Moves through the vent hole 21a while being restricted, and moves into the air chamber 21 to become the same internal pressure. Then, after the external energy is weakened or stopped, the air pressure inside the main body 2 and the air chamber 2 are reduced.
When the air pressure inside 1 is reversed, the high-pressure air accumulated in the air chamber 21 is gradually returned to the inside of the main body 2 to restore the main body 2 to the initial setting state, and the next external energy is repeated. It is configured as a means to be a low reaction force type pneumatic fender capable of preparing for receiving the air. Therefore,
When the fender receives external energy and compresses, the partitioned volume portion G in the entire body 2 increases the internal pressure to increase energy absorption, and gradually reduces the increased internal pressure to air. Since it is moved into the chamber 21 and accumulated, it is possible to suppress the generation of a strong reaction force immediately.

1B or the lid is provided in the backflow prevention structure, discharge or suction is set to one-way to increase the amount of movement, and when the air pressure inside the main body 2 is increased and reduced when the small-diameter vent hole 21a is provided. It is also possible to set the restoration time earlier or later by providing a difference in the amount of passage of air per unit time with the air chamber 21 in each case. In this case, the moving direction of the internal air and the flow amount of the time difference movement can be freely set according to the set pressure of the initial internal pressure or the purpose of buffering. In addition, this auxiliary device is applicable to existing pneumatic fenders. Further, although not shown, the same purpose can be achieved by installing the air chamber 21 outside the fixed pneumatic fender using a piping member.
