FIG. 1 is a schematic perspective view showing a deployed state of a floating pier according to the first embodiment of the present invention, and is a view showing a bag-shaped body in a pressurized state, and FIG. 2 is a diagram. It is a figure which shows the bag-like body of the floating type pier shown in 1 in the decompressed state.

With reference to these figures, the floating pier 1 is a rectangle made of a pair of long bag-shaped bodies 3a and 3b having airtightness formed of a flexible material such as rubber and wood having water resistance. It is composed of a plate-shaped body 5 in which a plurality of flat plate-shaped plate members 4a to 4p are continuously arranged side by side in the same direction as the length direction of the bag-shaped bodies 3a and 3b. Each of the bag-shaped bodies 3a and 3b is attached to the lower surfaces of the plate members 4a to 4p of the plate-shaped body 5 with an adhesive at intervals in the width direction of the plate-shaped body 5. As a result, each of the plate members 4a to 4p of the plate-shaped body 5 is in a state of being connected via the bag-shaped bodies 3a and 3b, so that each of the plate members 4a to 4p can rotate at each connecting portion.

Further, injection valves 6a and 6b are provided at one end of the bag-shaped bodies 3a and 3b in the longitudinal direction (the end of the plate-shaped body 5 located on the plate member 4a side). Then, a fluid supply / discharge means (not shown) such as an air compressor makes it possible to fill or discharge the fluid gas 8a, 8b inside the bag-shaped bodies 3a, 3b via the injection valves 6a, 6b. There is.

Further, on the lower surface 15a of the plate member 4a of the plate-shaped body 5, a belt 7 as a storage assisting means is attached at a position sandwiched between the bag-shaped bodies 3a and 3b. The belt 7 extends from the plate material 4a side toward the plate material 4p side so as to pass through the entire lower surface of the plate-like body 5. The effect configured in this way will be described later.

The bag-shaped bodies 3a and 3b of the floating pier 1 shown in FIG. 1 are in a pressurized state by filling the inside with gases 8a and 8b, and have a substantially cylindrical shape. When the floating pier 1 is floated on water in this state, although not shown, the bag-shaped bodies 3a and 3b are the plate members 4a to 4p of the plate-shaped body 5 in a state where a load such as a human load is applied to the plate-shaped body 5. It has a buoyancy to levitate the upper surfaces 14a to 14p of the above surface on water.

On the other hand, the bag-shaped bodies 3a and 3b of the floating pier 1 shown in FIG. 2 are in a depressurized state by discharging gas from the inside thereof, and have a flat shape. In this state, the plate-shaped body 5 is in a developed state in which all the upper surfaces 14a to 14b of the plate-shaped bodies 4a to 4p are exposed to the outside as shown in FIG. 2, and at least one of the plate-shaped bodies 4a to 4p described later. It is possible to switch between the stored state where the part is shielded from the outside. Further, the bag-shaped bodies 3a and 3b can be deformed according to the movement of the plate members 4a to 4p of the plate-shaped body 5 at their respective connecting portions.

Next, switching between the deployed state and the stored state of the floating pier 1 will be described.

FIG. 3 is a schematic perspective view showing a state in which the floating pier shown in FIG. 2 is in the process of transitioning from the deployed state to the stored state.

With reference to the figure, the plate-shaped body 5 of the floating pier 1 is wound while being rotated in the circumferential direction (arrow A1 direction) from the plate material 4p side toward the plate material 4a side. At this time, the winding of the plate-shaped body 5 can be assisted by pulling the belt 7 extending toward the plate material 4p side of the plate-shaped body 5 in the direction of the arrow A2. Further, the bag-shaped bodies 3a and 3b are deformed according to the movement of the plate-shaped body 5, and are wound together with the plate-shaped body 5.

FIG. 4 is a schematic perspective view showing a state in which the transition from the deployed state to the stored state of the floating pier shown in FIG. 2 is completed.

With reference to the figure, when the above-mentioned winding is advanced to the end, the plate-shaped body 5 and the bag-shaped bodies 3a and 3b have a shape of being wound in the circumferential direction, and the floating pier 1 is put into the stored state. The migration is complete. In this stored state, the upper surface of the plate material excluding the plate material 4a of the plate-shaped body 5 is shielded from the outside.

When the floating pier 1 is brought into the deployed state shown in FIG. 2 again, the floating pier 1 may be rotated in the direction opposite to the winding direction. Further, in the transition to the unfolded state, the bag-shaped bodies 3a and 3b may be used as the unfolding assisting means. Specifically, first, gas is injected into the bag-shaped bodies 3a and 3b by a fluid supply means (not shown). Then, although not shown, the bag-shaped bodies 3a and 3b gradually start to swell from the ends on the injection valves 6a and 6b side. When the gas injection is continued as it is, the bag-shaped bodies 3a and 3b and the plate-shaped body 5 rotate in the direction opposite to the arrow A3 direction in FIG. 3 due to the internal pressures of the bag-shaped bodies 3a and 3b, respectively. In the expanded state of the pressurized state shown in (1), the transition from the stored state to the expanded state and the injection of the gases 8a and 8b into the bag-shaped bodies 3a and 3b are completed at once.

By doing so, the entire shape of the floating pier 1 can be deformed within the range in which the plate-shaped body 5 can move, and the floating state and storage of the floating pier 1 can be changed according to the usage condition or the transportation condition. Since the state can be switched, the floating pier 1 can be easily installed, stored, and transported. Further, since the floating pier 1 can be deployed or stored while utilizing the rotational motion, the installation and storage of the floating pier 1 becomes easier. Further, the belt 7 which is a storage assisting means facilitates the transition of the floating pier 1 to the stored state, and the usability is improved.

FIG. 5 is a schematic perspective view showing a state in which the floating pier is in the process of transitioning from the deployed state to the stored state according to the second embodiment of the present invention, and is a view corresponding to FIG. , Is a schematic perspective view showing a state in which the transition from the deployed state to the stored state of the floating pier shown in FIG. 5 is completed, and is a view corresponding to FIG.

Since the configuration of the floating pier 21 according to this embodiment is basically the same as that of the first embodiment, the description here will not be repeated, and the differences will be mainly described.

With reference to FIGS. 5 and 6, in the floating pier 21 of this embodiment, a pair of wires 27a and 27b are provided on the plate-shaped body 25 as storage assisting means instead of the belt of the first embodiment. It is attached.

To specifically explain the attachment state of the wires 27a and 27b on the wire 27b side, first, on one end side (the side to which the bag-shaped body 23b is attached) of the plate members 24a to 24p in the width direction, the plate members 24a A through hole (not shown) is provided in the corner portion 29a on the side not adjacent to the plate member 24b. Next, through holes (not shown) are also provided at the corners 29b and 29c on the side where the plate member 24b and the plate member 24c are adjacent to each other. Further, through holes (not shown) are also provided at the corners 29d and 29e on the side where the plate member 24d and the plate member 24e are adjacent to each other. Further, also for the plate materials 24f to 24p, through holes (not shown) are provided in each plate material so that adjacent portions of the plate materials are opened one by one. The wire 27b is attached through this through hole (not shown).

The wire 27a has the same configuration as the wire 27b on the other end side (the side to which the bag-shaped body 23a is attached) of the plate members 24a to 24p in the width direction, and thus the description thereof will be omitted.

When the floating pier 21 formed in this way is transferred to the stored state, the wires 27a and 27b of the adjacent portions of the plate members 25 are placed in the bag-shaped bodies 23a and 23b under reduced pressure. Fold it in a bellows shape in the length direction so that the part that does not pass is a mountain fold. Then, the bag-shaped bodies 23a and 23b are also deformed into a bellows shape according to the movement of the plate material. Then, by fixing the plate material 24a side and pulling the wires 27a and 27b in the horizontal direction (arrow A3 direction), each of the plate materials 24a to 24p of the plate-shaped body 25 is further folded in the horizontal direction as it is, and the bag-shaped body 23a, 23b is also folded according to the movement of the plate material. Then, as shown in FIG. 6, the floating pier 21 by further pulling the wires 27a and 27b has a substantially rectangular parallelepiped shape, and the transition to the stored state is completed. In this state, the upper surface of the plate material 25 except for the plate materials 24a and 24p of the plate-shaped body 25 is shielded from the outside.

By doing so, the storage state is such that a plurality of floating piers 21 can be easily stacked.

When the floating pier 21 is to be expanded again, the plate-shaped body 25 of the floating pier 21 may be expanded in the direction opposite to the folded direction. Further, in the transition to the unfolded state, the bag-shaped bodies 23a and 23b may be used as the unfolding assisting means as in the first embodiment.

FIG. 7 is a schematic perspective view showing a state in which the floating pier is in the process of transitioning from the deployed state to the stored state according to the third embodiment of the present invention, and is a view corresponding to FIG. , Is a schematic perspective view showing a state in which the transition from the deployed state to the stored state of the floating pier shown in FIG. 7 is completed, and is a view corresponding to FIG.

Since the configuration of the floating pier 31 according to this embodiment is basically the same as that of the first and second embodiments, the description here will not be repeated, and the differences will be mainly described. ..

With reference to FIGS. 7 and 8, in the floating pier 31 of this embodiment, a belt 37 equivalent to the belt of the first embodiment is provided not on the lower surface 38a of the plate 34a but on the lower surface 38p of the plate 34p. ing.

When the floating pier 31 configured in this way is moved to the stored state, the belt 37 is pulled diagonally upward toward the front (in the direction of arrow A4), and the length of the plate-shaped body 35 with respect to the length is increased while lifting the plate material 34p. Fold it to shrink. At that time, the bag-shaped bodies 33a and 33b are deformed and folded according to the movement of the plate-shaped body 35. Then, as shown in FIG. 8, in the floating pier 31, the upper surfaces of the plate-shaped bodies 34a and 34p overlap each other, and the lengths of the plate-shaped bodies 35 and the bag-shaped bodies 33a and 33b in the length direction are reduced to about half. It will be folded into a fold, and the transition to the stored state will be completed. In this state, the upper surfaces of all the plate materials including the plate materials 34a and 34p of the plate-shaped body 35 are shielded from the outside.

By doing so, the bulk of the floating pier 31 is reduced, so that even if the height of the storage space is limited, it can be handled.

When the floating pier 31 is to be expanded again, the plate-shaped body 35 of the floating pier 31 may be expanded in the direction opposite to the folded direction. Further, in the transition to the unfolded state, the bag-shaped bodies 33a and 33b may be used as the unfolding assisting means as in the first embodiment.

Next, how to use such a floating pier will be described.

FIG. 9 is a perspective view schematically showing a first method of using the floating pier according to the first embodiment of the present invention, and FIG. 9 (1) is a view showing a deployed state of the floating pier. (2) is a diagram showing a stored state of a floating pier.

With reference to (1) in the figure, the floating pier 1 in this usage method is deployed on the water 47, and on the upper surface 14a of the plate material 4a of the plate-like body 5, the pier side metal fitting 41a is used as a means for fixing to the quay 48. , 41b and chains 42a, 42b are provided. It is desirable that the lengths of the chains 42a and 42b be set to a length that can correspond to the ascending / descending distance of the floating pier 1 that accompanies the rise and fall of the water level.

One of the chains 42a and 42b is attached to the pier side metal fittings 41a and 41b, and the other is attached to the quay side metal fittings 43a and 43b previously driven into the quay 48 by the quay side metal fittings 43a and 43b.

By doing so, the floating pier 1 is fixed to the quay 48, so that the floating pier 1 can be used stably. For example, the floating pier 1 can be used as a fishing pier as shown in (1) of the figure. It is easy to maintain safety even when using it.

Further, referring to (2) in the figure, in stormy weather, the floating pier 1 can be stored and pulled up on the quay 48 while being fixed to the quay 48. By doing so, the risk of the floating pier 1 being washed away or damaged by floating matter is reduced.

FIG. 10 is a schematic perspective view showing a second method of using the floating pier according to the first embodiment of the present invention.

Wire ropes 52a to 52d are attached. The other end of the wire ropes 52a to 52d is driven and fixed on the shore 49 by the piles 53a to 53d. The portion deployed on the water 47 functions as a simple pier, and small boats such as leisure boats 58a to 58c can come alongside.

By doing so, a part of the floating pier 1 is fixed to the shore 49, so that the floating pier 1 can be used stably even when it is used as a pier for getting on and off the small boats 58a to 58c. ..

Further, by extending the plate-shaped body 5 in the length direction and providing the ramp portion 55 on the lower surface thereof without attaching the bag-shaped body, it becomes easier for people (not shown) to come and go.

Further, although not shown, the risk of the floating pier being washed away or damaged can be reduced by pulling it up to the shore 49 as a stored state in stormy weather.

The receiving metal fitting 61 is further provided. As a result, the floating pier 1 can be towed by a small boat 68 or the like via a wire rope 62 as needed.

By doing so, the floating 47 can be moved while the floating pier 1 is deployed, so that the floating pier 1 can be easily transported when the installation location is changed.

It is also possible to temporarily recover the rescued victims as shown in the figure. Since the rescued victims 63a to 63e can be transported to a place where they can be towed while they are on the floating pier 1, the victims can be transported to the rescue facility faster, and the efficiency of rescue activities is improved. ..

FIG. 12 is a schematic perspective view showing a fourth method of using the floating pier according to the first embodiment of the present invention.

With reference to the figure, the floating pier 1 in this usage method can be connected to another floating pier on the upper surface of the plate-shaped body 5 on one end side (plate material 4p side) in the length direction. It is further provided with a U-shaped connecting pin 71 and a pin receiving hole 72, which are connecting means to be connected. The pin receiving hole 72 is directly formed in the plate-like body of the floating pier 1. Such a floating pier 1 is transferred to a plurality of installation locations, water 47, in a stored state together with another floating pier 74e having a similar pin receiving hole 73, and is brought into a deployed state. After that, the connecting pins 71 are inserted into the pin receiving holes 72 of the floating pier 1 and the pin receiving holes 73 of the floating pier 74e so as to be connected to each other in the length direction.
