Description

Ship including a float mounting device, a side float device and a side float device

The present invention relates to a float attachment device, a side float device in which a float is attached to the float attachment device, and a ship including the side float device. In particular, the present invention relates to a ship including a float mounting device, a side float device, and a side float device that can easily adjust the distance between the water surface and the float with the side float device attached to the ship.

As a result of the amendment of the law in November 2003, a license and ship inspection for maneuvering a ship with an overall length of less than 3 meters and an outboard motor of less than 2 horsepower are no longer necessary. In addition, improvements in materials for ship manufacturing have progressed, for example, durability has been improved for rubber boats, and ship hulls can be made lighter and more compact by manufacturing an integrally molded or split boat with FRP, etc. More people are enjoying it.

These ships are also used as disaster rescue boats to rescue victims in the event of disasters such as tsunami, storm surge, river flooding, etc., because they have little storage space and are easy to carry. .

By the way, a small ship may be overturned when a passenger is biased to one side of the ship and becomes unbalanced or receives a transverse wave. For this reason, in order to increase the safety of the ship, it is known to attach side floats (devices) serving as auxiliary buoyancy bodies of the hull to the left and right sides of the hull.

As a side float device, a structure is known that uses mounting brackets provided on the left and right side of the hull (boat body) and a band member provided with a connecting bracket (see Patent Document 1).

However, installation of the side float device described in Patent Document 1 has time and effort and is difficult to install on the sea. Therefore, the present inventors have developed a fender float device that anyone can install instantaneously by inserting and engaging the lock body of the fender float into the lock cylinder formed on the hull. (See Patent Document 2).

Utility Model Registration No. 3114619 Japanese Patent No. 5004185

By the way, the draft line of a small ship is more likely to change than a medium-sized or large-sized ship depending on the number and weight of passengers and the weight of the load such as a cooler box and fishing gear. However, the conventional side float device described in

Patent Documents

1 and 2 and the like cannot adjust the position from the water surface after being attached to the hull.

Therefore, as shown in FIG. 1 (1), when the boat 1 travels in a state where the inboard weight of the ship 1 is heavy and a part of the float body 3 of the side float device 2 is located below the surface of the water, the float body 3 becomes resistance and the traveling speed is increased. There is a problem of falling. Further, when the vehicle travels in a water area with a lot of drifting material after a typhoon or the like has passed, the drifting object may collide and damage the float body 3. Further, if the drifting object is caught between the hull and the float body 3, the side float device 2 may be damaged. In addition, if the drifting object is caught between the ship 1 and the float body 3, it creates water resistance, so the speed is further reduced and the arrival time to the destination is delayed, and the direction of the water flowing along the hull changes. There is a possibility of water entering the ship.

On the other hand, as shown in FIG. 1 (2), when the inboard weight of the ship 1 is light and the float body 3 of the side float device 2 is separated from the water surface, the resistance of water during traveling is reduced. However, when the ship 1 is shaken by waves or winds during berthing, the roll amplitude of the ship 1 increases as the distance H between the water surface and the float body 3 increases. For this reason, there is a problem that the occupant is likely to get seasick and that the stability is deteriorated when the occupant performs work or the like on the ship.

The present invention has been made in order to solve the above-mentioned problems, and as a result of extensive research, the hull is provided with a float fixing portion position adjusting mechanism that can adjust the position of the float fixing portion that fixes the float. It was newly found that the position of the float from the water surface can be adjusted easily and instantaneously even after the side float device is installed.

That is, an object of the present invention is to provide a ship including a float mounting device, a side float device, and a side float device.

The present invention relates to a ship including a float mounting device, a side float device, and a side float device shown below.

(1) A float fixing part for fixing the float,
A locking body that can be detachably attached to a locking cylinder provided in the hull of the ship,

A float fixing portion position adjusting mechanism that is fixed to the other end of the connecting rod and that can adjust the position of the float fixing portion with respect to the locking body;
Including float mounting device.
(2) The float fixing part position adjusting mechanism is
An inner cylinder fixed to the other end of the connecting rod,
An outer cylinder that is provided on the outside of the inner cylinder so as to be rotatable with respect to the inner cylinder, and is fixed to the float fixing portion;
The float mounting apparatus according to (1) above, including:
(3) The float fixing part position adjusting mechanism is
A hollow operating rod fixed to the outer cylinder,
A positioning pin slidable in the hollow operating rod;
Including a positioning hole formed in the inner cylinder,
The float mounting device according to (2), wherein the position of the float fixing portion is adjusted by engaging the positioning pin with the positioning hole.
(4) The float fixing portion position adjustment mechanism includes a rotation range adjustment mechanism,
The rotation range adjusting mechanism includes a long hole formed in the outer cylinder, and a convex part formed in the inner cylinder and movable along the long hole,
The float mounting apparatus according to (3) above.
(5) The float fixing part position adjusting mechanism is
An outer frame that is fixed to the other end of the connecting rod and is spaced apart from the locking body;
A sliding portion fixed to the float fixing portion and provided to be slidable with respect to the outer frame;
Locking means for locking the outer frame and the sliding portion;
The float mounting apparatus according to (1) above, including:
(6) The float mounting apparatus according to any one of (1) to (5) above, and a side float apparatus including a float.
(7) A ship including the side float device according to (6).

The side float device of the present invention can easily adjust the height of the float from the water surface even after being attached to the hull.
For this reason, the water resistance is reduced by moving the float away from the water surface before the ship travels, and the drift speed does not get caught in the side float device, so the traveling speed can be improved. The arrival time to the destination can be made faster. Further, by increasing the float position from the water surface, the distance between the center of gravity of the ship and the buoyancy is increased, so that the resilience of the ship is increased. Therefore, by setting the float away from the water surface, not only the traveling speed is improved, but also the safety during traveling is improved.

When the ship is moored after traveling, the distance between the float and the water surface can be shortened by lowering the float, or the float can be brought into contact with the water surface or partially submerged in the water surface. Therefore, when the hull is tilted due to a transverse wave or the like, the hull is immediately returned to its original state by the buoyancy of the float, so that the amplitude of roll is reduced, and sea sickness during fishing can be prevented. In addition, when conducting water quality surveys for environmental surveys, it is necessary for a person to stand on the boat and draw water from the surveyed area with a bucket or the like many times from the boat side. At that time, by adjusting the height of the float to greatly reduce the amplitude of the roll, it is possible to prevent the falling of water during the water pumping work and the fall of the sample water and the measuring instrument.

Furthermore, buoyancy increases as the amount of float that sinks to the surface of the water increases, and stability improves even when a load is applied to one of the ridges. Therefore, when the water-spilling person is rescued, the rescue operation is performed after sinking a lot of the float below the surface of the water, so that it is possible to effectively prevent the ship from tilting and flooding into the ship when the water-spilling person is pulled up.

Hereinafter, a ship including a float mounting device, a side float device, and a side float device will be described with reference to the drawings.

FIG. 2 is a view showing the appearance of a ship including the side float device of the present invention. The ship 1 shown in FIG. 2 is a split-type ship, and is composed of two parts, a bow side 1a and a stern side 1b, and the bow side 1a and the stern side 1b are connected by a connecting part 1c. A locking cylinder (not shown) is attached to the hull side surface of the stern side 100 a of the port 100 and the hull side surface of the stern side 101 a of the starboard 101. The side float device 20 includes a float attachment device and a float 21 (FIG. 2 fixes the float 21 to the float fixing portion 31 of the float attachment device). The side float device 20 of the present invention can be attached to the ship 1 by detachably inserting a locking body of a float mounting device, which will be described later, into the locking cylinder.

The ship 1 is not particularly limited as long as the ship 1 can be attached with a locking cylinder that engages with the side float device 20. For example, in addition to the split boat shown in FIG.

Fig. 3 (1) is a perspective view showing the external appearance of the first embodiment of the float mounting device 30, and Fig. 3 (2) is a side view. A float mounting device 30 shown in FIGS. 3 (1) and 3 (2) is attached to and detached from a float fixing portion 31 for fixing a float (a virtual line in FIG. 3 (1)) and a locking cylinder provided on a ship hull. A locking body 32 that can be freely attached, a connecting rod 34 having one end fixed to the locking body 32, and a float fixing portion position adjusting mechanism that can be fixed to the other end of the connecting rod 34 and adjust the position of the float fixing portion 31. 40 at least. In the first embodiment shown in FIGS. 3A and 3B, two connecting rods 34 are formed, and the other ends of the connecting rods 34 are fixed to both ends of the inner cylinder 41 of the float fixing portion position adjusting mechanism 40. ing. The float fixing portion 31 is fixed to the outer cylinder 42 of the float fixing portion position adjusting mechanism 40. If the float fixing | fixed part 31 is a shape which can fix the float 21, there will be no restriction | limiting in particular. In the example shown in FIG. 3, the float fixing portion 31 is configured with ring-shaped members attached to both end sides of the plate-shaped member 311 that is fixed to the outer cylinder 42. For example, the cylindrical body is a burner. The float fixing portion 31 may be formed by integrally forming the ring-shaped member and the plate-shaped member 311 by a method such as cutting. Alternatively, the float fixing portion 31 may be formed by the plate-like member 311, the belt locking member formed on the plate-like member 311, and the belt, and the float may be fixed by the belt.

FIG. 4 is a cross-sectional view taken along the line AA of the float mounting device 30 shown in FIG. In FIG. 4 and FIG. 5 to be described later, in order to facilitate understanding of the positional relationship of the float fixing portion 31, the locking body 32, the ring-shaped member of the float fixing portion 31, and the connecting rod 34 are indicated by virtual lines. Yes. FIG. 4 shows a state in which the float fixing portion 31 is lowered (when mounted on the hull, the distance between the float fixing portion 31 (float 21) and the water surface is short, or the water surface and the float fixing portion 31 (float 21) are in contact with each other). State). Hereinafter, the configuration and operation of the float fixing unit position adjusting mechanism 40 of the first embodiment will be described with reference to cross-sectional views. The float fixing portion position adjusting mechanism 40 includes (a) an inner cylinder 41 whose both ends are fixed to the other end of the connecting rod 34, and (b) an inner cylinder 41 which is fixed to the float fixing portion 31 and provided outside the inner cylinder 41. (C) a hollow operation rod 43 fixed to the outer tube 42, (d) a rod-shaped portion 441 slidable in the hollow operation rod 43, and a rod-shaped portion A positioning pin 44 composed of an operating portion 442 which is fixed to 441 and protrudes from a hole 431 formed in the hollow operating rod 43; (e) a positioning hole 45 formed in the inner cylinder 41; and (f) an upper end of the rod-shaped portion 441. And a biasing member 46 such as a spring that biases the positioning pin 44 downward. Since the rotation of the inner cylinder 41 and the outer cylinder 42 is locked by inserting the tip end portion of the positioning pin 44 into the positioning hole 45, the position of the float fixing portion 31 (float 21) from the water surface can be fixed. it can.

FIG. 5 (1) is a diagram illustrating a state where the float fixing unit 31 of the first embodiment is fixed at a position away from the water surface. When the position of the float fixing portion 31 is moved away from the water surface, the positioning pin 44 is pulled upward, the tip of the positioning pin 44 is pulled out from the positioning hole 45, and then the operating rod 43 is tilted in the direction of the arrow to move the outer cylinder 42. Is rotated with respect to the inner cylinder 41, and the tip of the positioning pin 44 may be inserted into another positioning hole 45 at a desired position. Since the positioning pin 44 is lowered by gravity and can lock the rotation of the inner cylinder 41 and the outer cylinder 42, the urging member 46 is not essential and may be formed as necessary.

The number of the positioning holes 45 is not particularly limited, and may be formed so that the float fixing portion 31 can be locked at a desired position. The position of the float fixing portion 31 from the water surface is adjusted by rotating the outer cylinder 42 relative to the inner cylinder 41 as described above. Therefore, if the length of the connecting rod 34 is short, the distance until the operating rod 43 comes into contact with the hull is shortened, and the rotation distance of the outer cylinder 42 (the distance traveled from the water surface of the float fixing portion 31) is shortened. The length of the connecting rod 34 may be adjusted as appropriate in consideration of the distance separating the float fixing portion 31 from the water surface. The vertical positional relationship between the locking body 32 and the inner cylinder 41 can be adjusted by the orientation of the connecting rod 34. For example, in the embodiment shown in FIG. 5 (1), the inner cylinder 41 is substantially the same as the vicinity of the lower end of the locking body 32. However, if the position of the inner cylinder 41 is set higher than the position shown in FIG. Since the rotation angle of the rod 43 is increased, the rotation angle of the float fixing portion 31 can be increased. FIG. 5 (1) shows an example of the direction in which the float fixing part 31 (float 21) is separated from the water surface, but conversely, the float fixing part 31 (float 21) is rotated in the direction of sinking in water. You may form the positioning hole 45 in the position which can be locked.

In the first embodiment, with the finger hooked on the operation portion 442 of the positioning pin 44 and the rod-shaped portion 441 pulled up, the float fixing portion 31 is separated from the water surface by pulling the operation rod 43 toward the hull side by the lever principle. Can be adjusted in the direction or sinking direction. Since the first embodiment uses the principle of the lever, the position of the float fixing part 31 can be adjusted with one hand and with a small force. It is not limited to the first embodiment.

For example, as another embodiment in which the float fixing part position adjusting mechanism 40 is configured using the outer cylinder 42 and the inner cylinder 41, for example, a hole is formed in the outer cylinder 42 instead of the operation rod 43, and the float fixing part The float fixing portion 31 is rotated using a rope 31 or the like locked to the float 21, and a pin or the like is inserted when the holes of the outer cylinder 42 and the inner cylinder 41 coincide with each other to rotate the outer cylinder 42 and the inner cylinder 41. The movement may be locked.

Further, among the components (a) to (f) in FIGS. 4 and 5 (1), (c) the hollow operating rod 43 is not formed with a hole 431, and (d) the positioning pin 44 is The rod-shaped portion 441 alone may be formed, the other end of the rod-shaped portion 441 may be fixed to the knob 432, and the knob 432 may be detachable from the hollow operation rod 43. The knob 432 is pulled out from the operation rod 43 to disengage the tip end portion of the pin 44 from the positioning hole 45, and after rotating the operation rod 43, the knob 432 is pushed into the operation rod 43 so that the tip portion of the pin 44 is moved to a different positioning hole. 45 can be inserted and fixed. Further, if a part of the knob 432 has a diameter substantially the same as the inner diameter of the hollow operation rod 43 so that the knob 432 and the operation rod 43 can be engaged with each other by friction, (f) the positioning pin 44 is urged downward. It is not necessary to form the biasing member 46 such as a spring.

FIG. 5 (2) is a bottom view showing an example in which the float fixing portion position adjusting mechanism 40 further includes a rotation range adjusting mechanism, and is a view seen from the direction of the arrow in FIG. 5 (1). 5 (2) includes a long hole 421 formed in the outer cylinder 42 and a convex part 411 formed in the inner cylinder 41, so that the convex part 411 can move along the long hole 421. It has become. If the rotation range of the operation rod 43 is larger than both ends of the row of the plurality of positioning holes 45, for example, when the float fixing portion 31 is fixed at a position farthest from the water surface, the operation rod 43 is tilted too far to the hull side. There is a possibility that the tip of the positioning pin 44 passes through the end of the positioning hole 45. However, by adjusting the length of the long hole 421 so that the holes at both ends of the row of the positioning holes 45 coincide with the tips of the positioning pins 44 when the convex portion 411 contacts the end of the long hole 421, Convenience at the time of adjusting the float fixing | fixed part 31 to the position most distant from the water surface or the nearest position improves.

The convex portion 411 is not particularly limited as long as it can move along the long hole 421. For example, a metal piece may be fixed to the inner cylinder 41 by welding or the like, or the protrusion 411 may be formed by forming a hole in the inner cylinder 41 and fitting a screw or the like. In the example shown in FIG. 5 (2), the rotation range adjustment mechanism is formed on the bottom portion on the opposite side to the operation rod 43, but there is no particular limitation as long as it is other than the location where the positioning hole 45 is formed. For example, it may be formed on the side of the operation rod 43.

FIG. 6 (1) is a side view of another embodiment of the float fixing part position adjusting mechanism, and FIG. 6 (2) is an enlarged front view of the float fixing part position adjusting mechanism. The float fixing part position adjusting mechanism 50 shown in FIG. 6 is fixed to the other end of the connecting rod 34 and formed away from the locking body 32, for example, fixed to the outer frame 51 and the float fixing part 31 formed substantially in parallel. It includes at least a sliding portion 53 provided to be slidable with respect to the outer frame 51 and formed with a knob 52, and a locking means for locking the outer frame 51 and the sliding portion 53. The locking means is not particularly limited as long as the outer frame 51 and the sliding portion 53 can be locked. For example, in the example shown in FIG. 6B, an eccentric cam (not shown) is formed in the sliding portion 53, and the pin 52 is moved from the portion that slides in the outer frame 51 of the sliding portion 53 by rotating the knob 52. 54 is taken in and out and inserted into a hole formed in the outer frame 51. Further, an eccentric cam or the like may not be formed, and a hole may be formed in the outer frame 51 and the sliding portion 53, and locked using a pin or the like at a position where the holes match.

Each element constituting the float mounting device 30 may be formed of a rust-resistant metal such as stainless steel.

The side float device 20 only needs to attach the float 21 to the float fixing portion 31 of the float attachment device 30. The float 21 is not particularly limited as long as it generates buoyancy, and a well-known ship float can be used. However, the float 21 is used for preventing a shock caused by a collision with a quay when a large ship is berthing and for preventing damage. A fender float having a structure that is excellent in impact resistance, water resistance, light resistance and the like is preferable.

FIG. 7 is a diagram showing an outline of the side float device 20 to which a fender float is attached as the float 21. The fender float 21 is an annular cylinder having both ends converged, and is attached so that the annular cylinder part of the fender float 21 is fitted to the float fixing part 31 of the float attachment device 30. By adjusting the sizes of the float fixing part 31 and the fender float 21 so that the outer peripheral part of the fender float 21 where the float fixing part 31 is not fitted is formed in an expanded shape, the float fixing part 31 and the fender float are adjusted. 21 can be prevented from coming off. In addition, although the ring-shaped member of the float fixing | fixed part 31 shown in FIG. 7 is two, if the float 21 attached using the float fixing | fixed part 31 is hard to drop off, there will be no restriction | limiting, A ring-shaped member is 3 It may be more than this. Or the ring-shaped member of the float fixing | fixed part 31 may be formed by one by expanding the width of a ring-shaped member and increasing the area which contacts an annular cylinder part.

FIG. 8 is an explanatory diagram of members for detachably attaching the side float device 20 to the ship 1. A locking cylinder 60 is attached to a ship 1 (not shown) with a screw or the like (not shown). The locking cylinder 60 is provided with a triangular base 61 that follows the curvature of the hull at the attachment location, a bent portion 62 that follows the shape of the upper edge of the hull of the ship 1, and a locking cylinder 63. The locking cylinder 63 is preferably a hollow body in which the upper end 63a and the lower end 63b are opened in order to allow water to pass through, drying, and insertion (insertion) of the locking body 32. A locking piece 64 is provided on any side surface 63 c of the locking cylinder 63.

On the other hand, a hook 66 that is locked to the locking piece 64 is pivotally attached to the locking body 32 of the side float device 20 via the mounting shaft 65. As an example, this hook 66 is a locking body. 32 is provided on the side surface. The hook 66 is provided with a spring (not shown) to control the return of the hook 66. When the locking body 32 of the side float device 20 is inserted into the locking cylinder body 60 attached to the hull, the hook portion 661 of the hook 66 is locked to the locking piece 64, and the side float device 20 is fixed to the ship 1. Can do. For this reason, the side float device 20 does not come off the ship 1 even when subjected to impacts such as strong winds, waves, and floating objects while traveling and / or mooring.

When the float is moved away from the water surface, the buoyancy, which is the center of the force that floats the ship, moves to a position away from the water surface. The restoring force that prevents the ship from overturning increases according to the distance between the center of gravity of the ship and the buoyancy. Therefore, even if the float is locked at a position away from the water surface, the safety of the side float device that prevents overturning and the like is not impaired. Further, not only during traveling but also during berthing, if the person is strong against seasickness or the like, it is possible to prevent capsizing due to a sudden transverse wave or the like by raising the float from the water surface. Conversely, increasing the amount of float that sinks to the surface of the water increases the buoyancy and improves the stability of the ship even when a load is applied to one of the anchors. For this reason, when the water-spilling person is rescued, the rescue operation is performed after sinking a lot of the float below the surface of the water, so that it is possible to effectively prevent the ship from tilting and flooding into the ship when the water-spilling person is pulled up. Therefore, by using the side float device of the present invention, it is possible to balance safety and comfort according to the weather and the passenger.

Since the side float apparatus of the present invention can easily and instantaneously adjust the position of the float from the water surface even after being attached to the ship, the convenience of the ship can be improved. Therefore, it is useful as equipment for small ships.
