[Industrial applications]

 The present invention relates to an assembled boat and a float used for the assembled boat.

[0002]

[Prior art]

 Conventionally, an assembly type, for example, for leisure, which is equipped with a plurality of floats, a support leg supporting the float, a passenger deck provided above the support leg, and a propulsion means attached to the deck so that they can be disassembled and assembled. The boat is known. An example of this is the “floating body play equipment” described in JP-A-1-192375. The floating playground equipment has a sail as a propulsion means.

[0003]

[Problems to be solved by the device]

 Since the assembled boat of this type does not have means for adjusting the relative position of the float and the deck after assembly, the height of the deck with respect to the water surface cannot be arbitrarily changed. In addition, yachts (sailboats) generally do not have a full-scale keel because they impair portability. Therefore, if the deck is too high, it is difficult to get on and off, and the hull is prone to tilt and waves due to the number of passengers, the condition of the water surface, the propulsive ability of the outboard motor and the sail, etc. Furthermore, there was a problem that handling after assembling on land was relatively difficult.

Therefore, the present invention provides a prefabricated boat that allows the height of the deck to be changed, and can prevent the hull from shaking during navigation, and also provides ease of use on land. The purpose is to improve riding comfort.

[0005]

[Means for Solving the Problems]

 For this purpose, the following assembled boat and float were created. That is, according to the first aspect of the present invention, in the assembled boat including the predetermined number of floats, the supporting legs supporting the floats, and the deck above the supporting legs for disassembling and assembling, the supporting legs are rotatable on the deck. And an adjusting mechanism capable of changing the rotation angle position of the support leg between the support leg and the deck. According to the invention of claim 2, in the assembly type boat, The hydrofoil is supported so as to be rotatable and vertically movable about a substantially horizontal axis, and is equipped with a hydrofoil tilting mechanism that connects the hydrofoil with the support leg to link the hydrofoil with the movement of the support leg. It is characterized by being. Further, the float of the invention of claim 3 is provided with a tube which is formed to be expandable and contractible, and which expands in an annular shape around a mounting portion which is rotatably mounted on the supporting leg when gas is press-fitted. It is characterized by being.

[0006]

[Action]

 Therefore, in the device according to the first aspect, the relative position between the support and the deck can be changed by operating the adjusting mechanism, and the height of the deck can be arbitrarily set. In the device according to the second aspect, when the hull is tilted and the relative position between the deck and the float is changed, the hydrofoil is tilted in conjunction with the movement of the supporting leg, so that the tilt of the deck can be suppressed. Further, in the device according to the third aspect, by rolling the float, the boat can be easily moved on land, and the degassed float can be compactly stored when the boat is disassembled.

【Example】

 A first embodiment of the present invention will be described. FIG. 1 is a side view of the assembled boat, and FIG. 2 is a plan view taken along the line AA of FIG. In both figures, in the deck 1, the square pipes 2a to 2d are framed in a substantially rectangular shape, and the columns 3a to 3d are erected at their four corners, and the upper ends of the columns 3a to 3d are connected to the substantially rectangular shape by the horizontal pipes 4a to 4d. The space between the square pipes 2b and 2d is reinforced by the horizontal pipes 5a to 5c and assembled. The pipes and stanchions are connected using joint pins and split pins (not shown), and can be disassembled and assembled without using any tools. As shown in FIG. 3, a hinge 2e is attached to the central portion of the square pipe 2a, and a slide joint 2f is attached inside the square pipe 2a. Then, during assembly, the lever 2g is operated to position the slide joint 2f at the bent portion to hold the square pipe 2a straight, while at the time of disassembly, the slide joint 2f is slid and removed from the bent portion. The square pipe 2a is adapted to be folded. The other square pipes 2b to 2d also have the same folding structure as the square pipe 2a. Then, referring to FIG. 1, a floor plate 6 (deck) is placed on the square pipes 2a to 2d.

Support shafts 2h to 2h extending substantially horizontally are pivotally supported at the tips of the square pipes 2a, 2c projecting from the four corners of the deck 1 in the front-rear direction (left and right in the drawing), and swing shafts 2h to 2h are supported. An intermediate portion of the arms 7 to 7 (also referred to as a supporting leg) is rotatably supported. A float 8 (described in detail later) is rotatably attached to the lower end of each swing arm 7. A guide member 7a having an internal thread is rotatably attached to the upper end of the swing arm 7 as shown in FIG. 4 in one representative example, and the threaded rod 9 is screwed onto the internal thread. I am fit. A support metal 9a loosely fitted to the lower part of the neck of the threaded rod 9 is rotatably attached to the support column 3a (the same applies to 3b to 3d). When the threaded rod 9 rotates, the guide member 7a moves. It is adapted to move along the threaded rod 9. In the figure, 9c is a stopper that stops the axial movement of the threaded rod 9, and the head 9b of the threaded rod 9 has the same hexagonal shape as the head of the bolt.

Since the adjusting mechanism that determines the rotational angle position of the swing arm 7 is configured as described above, the threaded rod 9 is rotated to rotate the swing arm 7, thereby allowing the float 1 to float on the deck 1. The relative position of 8, that is, the height of the deck 1 can be arbitrarily adjusted. 1 and 2, the outboard motor 1b is mounted on the deck 1 through the mounting base 1a, and the steering lever 1c extends upward from the outboard motor 1b.

Next, the float 8 will be described. The float 8 is, as shown in FIG. 5, an axle 10 attached to a swing arm 7, and wheel wheels 11 and 12 made of resin, for example, which are attached to the axle 10 so as to be rotatable and axially slidable, A rubber tube 13 for, for example, an automobile tire, which is supported by the wheel disks 11 and 12, and a holder 14 that holds the tube 13 so as to wrap the tube 13 are formed. Although not shown, bearings may be interposed between the axle 10 and the wheel discs 11 and 12, and between the axle 10 and the swing arm 7.

Here, a method of manufacturing the float 8 will be described. FIG. 6A shows the developed state of the holding body 14. This holder 14 is made by cutting a sheet made of polyethylene, for example, into strips 14a to 14a, which are connected to each other by connecting bands 14b to 14e. It was sewn along. However, as shown in FIG. 6B, the connecting band 14e is provided with a space 14f capable of widening the space between adjacent strips at a predetermined interval. If the above-mentioned sheet itself has sufficient strength, it is possible to make a cut in a single sheet and attach the stainless wires 15a to 15c and the connecting band 14e to it. Alternatively, the whole tube may be wrapped with a mesh instead of the sheet. The vertical dimension (length of the strip) of the holding body 14 is the circumference of the expanded section of the tube 13, and the horizontal dimension (length of the connecting band) is formed on the outer circumference of the wheel discs 11, 12. The outer peripheral grooves 11a and 12a (see FIG. 5) are set to have substantially the same circumference.

When assembling the float 8, referring to FIG. 5, the stainless steel wires 15a and 15b are wound around the outer peripheral grooves 11a and 12a of the wheel disks 11 and 12, and the holding body 14 is fixed to the connecting band 14d side. Is unfixed. Then, the evacuated tube 13 is placed along the outer circumferences of the wheel discs 11 and 12 and then wrapped around the holding body 14, and the remaining stainless wire 15c is wound around the outer circumferential groove 11a and fixed. The ends of the stainless wires 15a to 15c are screwed to the wheel discs 11 and 12. The float 8 configured as described above expands into a circular ring of a predetermined size when air is fed into the tube 13 by using an air pump, and contracts when the air is removed so that the wheel disks 11 and 12 are mutually separated. approach.

As described above, in the assembled boat of the present embodiment, the swing arm 7 is rotated by rotating the threaded rod 9 of the adjusting mechanism with an electric tool or the like not only during assembly but also during navigation. Thus, the relative position of the float 8 with respect to the deck 1, that is, the height of the deck 1 can be arbitrarily adjusted. Moreover, since this adjusting mechanism is a method of rotating the swing arm 7, the structure is relatively simple, and disassembly and assembly are easy. Further, since the float 8 is attached to the tip of the swing arm 7 projecting from the deck 1, the stability of the deck 1 in the central portion of the boat is good, and the float 8 acts as a cushion at the time of berthing. Furthermore, by rolling the float 8 on land, the boat can be moved easily, and when disassembled, air can be evacuated from the float 8 for compact storage.

Next, a second embodiment will be described. FIG. 7 is a side view of the assembled yacht, FIG. 8 is a bottom view mainly showing the hydrofoil, and FIGS. 9 and 10 are partially enlarged views of the side surface of the yacht. As shown in FIGS. 7 and 8, the assembled yacht is roughly divided into a deck 1, four swing arms 7, a float 8, hydrofoils 20, a mast body 21, and a sail 22. The basic structure of the deck 1, the swing arm 7, the float 8 and the adjusting mechanism is almost the same as that of the assembled boat of the first embodiment described above, and therefore the description thereof is omitted and the other structures will be described below. Describe.

First, the hydrofoil 20 and the hydrofoil tilting mechanism will be described. The two hydrofoils 20 on the left and right are formed in an inverted T-shape in cross section, and are composed of an elongated vane 20a and a vertical plate 20b provided perpendicularly to the vane 20a. The vertical plate 20b has a mounting hole 20c. , 20d are formed at the front and rear positions. On the other hand, as shown in FIGS. 9 and 10, four prop pipes 23a to 23d are provided at fixed positions of the deck 1, and the hydrofoil support pipes 24a to 24d are vertically arranged on the prop pipes 23a to 23d. It is fitted so that it can slide in any direction. Of these, 23b, 23c, 24b, 24c are shown in parentheses because they are hidden by the corresponding members on the front side of the drawing.

On the left and right sides of the bow (left side in the figure), the lower end portions of the hydrofoil support pipes 24a, 24b are inserted into the mounting holes 20c and then supported by the joint pins 20e so as to be rotatable about a horizontal axis. The lower end portions of the hydrofoil support pipes 24c and 24d on the left and right sides of the stern are inserted into the mounting holes 20d and supported by a mounting tool 20f so as to be rotatable about a horizontal axis. On the other hand, the upper ends of the hydrofoil support pipes 24a to 24d are supported by belt-shaped rubber and wires so as to be vertically movable, as described below.

Next, the support structure of the upper and lower hydrofoil support pipes 24a and 24b on the bow side will be described. As shown in FIG. 9, a belt-shaped rubber 27 mounted between the upper stopper 25 provided on the upper ends of the hydrofoil support pipes 24a and 24b and the lower stopper 26 provided on the deck 1 side is provided. The hydrofoil support pipes 24a and 24b are always urged downward. The wire 28, one end of which is connected to the upper stopper 25, passes through the pulley 29a attached to the column 23e of the deck 1 and the pulley 29b attached to the column pipes 23a, 23b, and the upper end of the swing arm 7. Connected to the department. Unlike the first embodiment described above, the stopper 9c is provided at the middle position of the threaded rod 9, and the distance between the head 9b of the threaded rod 9 and the stopper 9c is the height of the deck 1. After the setting, the movable range of the swing arm 7 with respect to the deck 1 is appropriately set. That is, the buoyancy of the float 8 on the bow side always acts so as to pull the threaded rod 9 almost downward through the swing arm 7, but when the yot tilts and the height of the deck 1 changes. In response to this, the swing arm 7 is rotated to push up the threaded rod 9, the band-shaped rubber 27 is contracted, and the hydrofoil support pipes 24a and 24b are pushed out downward.

Next, the support structure of the upper and lower hydrofoil support pipes 24c and 24d on the stern side will be described. As shown in FIG. 10, the wire 28a whose one end is connected to the upper stopper 25 provided at the upper ends of the hydrofoil support pipes 24c and 24d passes through the pulley 29a attached to the column 23g of the deck 1. It hangs down and is connected to the band-shaped rubber 27a via a connecting tool 25a. The lower end of the belt-shaped rubber 27a is fixed to the lower stopper 26 provided on the deck 1 side, and the belt-shaped rubber 27a constantly urges the hydrofoil support pipes 24c and 24d upward. The wire 28b, one end of which is connected to the lower surface of the upper stopper 25, is connected to the upper end of the swing arm 7 via the pulley 29b attached to the support pipes 23c and 23d. The configuration of the threaded rod 9 is the same as that on the bow side.

Therefore, even on the stern side, the buoyancy of the float 8 always acts so as to pull the threaded rod 9 almost downward through the swing arm 7, but the yacht leans and the height of the deck 1 changes. Accordingly, the swing arm 7 is rotated to push up the rod 9 with a screw, the band-shaped rubber 27a is contracted, and the hydrofoil support pipes 24c and 24d are pulled up.

Since the hydrofoil tilting mechanism is configured as described above, when the yacht tilts and the deck 1 is lifted, the swing arm 7 rotates in a direction to push down the float 8 accordingly, and the belt-shaped rubber 27, The elastic force of 27a pushes down the front end of the hydrofoil 20 and pulls up the rear end. That is, even if the yacht leans when receiving a crosswind, the hydrofoil 20 rarely appears on the surface of the water, and the hydrofoil 20 tilts in accordance with the tilt of the deck 1 to suppress the tilt of the yacht.

Further, as shown in FIG. 10, a ladder pipe 30 is slidably inserted into each of the left and right hydrofoil support pipes 24c, 24d arranged on the stern side, and the lower end of the ladder pipe 30 is inserted. A rudder 31 is attached to the section, and a steering lever 32 is attached to the upper end. The two left and right ladders 31 and 31 are connected to each other by wires 31a and 31b so as to interlock with each other (see FIG. 8).

Next, the mast will be described. As shown in FIGS. 7 and 9, a support portion 40 for supporting the mast body 21 is provided at a position near the center front of the deck 1. The mast main body 21 fixed on the deck 1 by the support portion 40 has a five-stage connection structure of the masts 21a to 21e, and the upright posture is held by appropriately stretched wires 41 to 41. . A boom mounting portion (details will be described later) is provided between the masts 21a and 21b, and in the present embodiment, the wire 41 is provided at each upper end portion of the masts 21a, 21c, 21e and the lower end portion of the mast 21b. To 41 are hung, and the other ends of the wires 41 to 41 are fixed to the columns 3a and 3b and the left and right two columns 23f via a turnbuckle (not shown).

The support section 40 is provided with a jack mechanism capable of lifting the mast body 21. In this jack mechanism, as shown in FIG. 9, a nut 42a having female screws formed on both left and right sides of an abutting portion that abuts a lower end of the mast 21a is vertically fitted into a supporting portion 40 and is screwed into the nut 42a. The tip of the jack screw 42b is brought into contact with the deck 1 side. Therefore, by rotating the jack screw 42b, the entire mast is moved up and down through the lifting and lowering of the nut 42a, so that the tension of each wire can be easily adjusted at once during disassembly and assembly.

A boom 43 extending substantially horizontally is attached to the mast body 21 as shown in FIG. The structure of the boom mounting portion will be described below. As shown in FIG. 11, the cylindrical joint body 45 is provided with vertically extending connecting rods 46 and 47 rotatably via bearings 48 and 49, and the connecting rods 46 and 47 are provided with masts. 21a and 21b are inserted. Further, a through hole for penetrating the boom 43 is opened in the joint body 45, and a bearing 51 for supporting the boom 43 is attached to a mounting plate 50 of the joint body 45. A handle 52 for rotating operation is attached to the rear end of the boom 43 protruding from the bearing 51, while a stopper 53 that can appropriately prevent rotation of the handle 52 is provided on the attachment plate 50.

Therefore, the boom 43 is rotatable about its axis and is supported so as to be rotatable about its mast axis. When the handle 52 is turned, it is a substantially triangular shape stretched between the mast body 21 and the boom 43. The sail 22 can be wound up. Further, the boom 43 can be swung by rotating the joint body 45, but the swivel range is about 120 before the boom 43 interferes with the wires 41 to 41 in this embodiment. °. As described above, the mast of this embodiment has a structure that can be easily disassembled and assembled.

Next, a usage mode of the float 8 different from the first embodiment will be described. FIG. 12 shows a state in which the float is attached to the outside of the tire of the vehicle. In the figure, a female screw is formed at the tip of the mounting bolt 60, and this is screwed into the hub bolt 61 instead of the hub nut to connect the float 8 to the hub 62. In the figure, 63 is an axle, 64 is a wheel, 65 is a spacer for positioning the wheel disc, and 66 is a tire. By mounting the float 8 on the wheels as described above, it is possible to prevent the vehicle from being submerged in water during a flood. In addition, the vehicle can be easily converted into amphibious land, which facilitates driving in shallow lakes, making it suitable for leisure purposes. In this case, if the outer peripheral portion of the float 8 is equipped with a water scraper, the wheel driving force can also be used as a propulsion means.

[Effect of device]

 As described above, in the assembled boat of the present invention, since the height of the deck can be changed after assembly, it is possible to prevent waves and splashes from being easily splashed on the occupants, and the deck can be lifted up and down to make it easier to get on and off. be able to. In addition, since the hydrofoil prevents the yacht from tilting when sailing, cross wind stability is good. In addition, the annular float can reduce shocks such as when docking, which makes it easy to handle the boat on land and allows compact storage when disassembled. Therefore, the assembled boat has good usability and riding comfort, and has the effect of making leisure comfortable.
