〔Example〕

Next, with reference to the accompanying drawings, the present invention will be described as a specific embodiment to provide an understanding of the present invention. First, FIG. 1 is a partial plan view showing a floating body attached to the left and right of an automobile. In addition, because of the four-wheel drive vehicle, a total of four rotary propellers are used. And the top shows the front of the car. And, based on the reference numerals, first, a general four-wheel drive (4WD) 11 is provided with four tires 10 in total, front, rear, left and right. And the rotary connection part 2 is connected to each wheel, and this is for transmitting the driving source of the tire to the floating body side (attached to the wheel of the tire or attached to the tire attachment) and 1 or less. About explanation, since it is four-wheel drive, it includes other three places in the explanation of one place. And 6 is a clutch. This is done with a pin clutch or the like so as not to use the driving loss of the reserve when driving with floating bodies on both sides while traveling on land (remove the lock pin 30 in FIG. Cut). In this case, even when the levitating body is attached in parallel (position in the normal water running state), the levitating body is folded at a right angle when traveling on land (twisting 90 ° when the rotary connecting portion 2 is considered horizontal). State) Both can be used when driving. The universal joint 1 is attached for the following effect. This changes the dimension (secondary or tertiary) in the driving direction. In this case, a spline may be used together. This is to adjust the change in the distance of the straight line (+, −) when the dimension changes. Next, the rotary propulsion unit 3 will be described. The state of FIG. 2 is a cross-sectional view of the enclosure, and therefore, the rotary propulsion unit 3 includes a blade 7 that rotates about a rotation axis (this is a kind of water wheel that is a basis of propulsion force). And the shaft shaft after the universal joint and its bearing 13 are supported on the levitating body 4, and the levitating body 4 including the rotary propulsion unit 3 is attached to the left and right sides of the vehicle. Levitate the entire vehicle, including the car. Reference numeral 8 denotes a floating body connecting bar that connects the floating bodies, and this is for connecting the floating bodies 4 to stabilize the floating body 4, and placing a car on the floating bodies 4 It is also what is directly supported by 4. Reference numeral 31 denotes a connecting portion between the floating body connecting bar 8 and the floating body 4. Reference numeral 5 denotes a wheel for supporting a part of the weight of the levitated body 4 when traveling on land. The levitation body 4 includes a front wheel portion and a rear wheel portion including a floating portion, and the rotary propulsion device 3 is supported on the levitation body 4 via the bearing portion 13 as described above.

Next, FIG. 2 is a partial front sectional view of the position of the wheel (tire portion) of the floating body. In this case, the rotary connecting portion 2 is in a state before being connected to the wheel of the wheel. Of course, the connecting portion hole 19 of the rotary connecting portion 2 is used for connection to a wheel hole or the like with a bolt or the like (of course, the tire attachment of FIG. 5 can also be used). The bearing 13 to which the blades 7 are assembled and also supports (holds) the shaft 26 is appropriately supported by the floating body 4 by a pedestal (frame) or the like. FIG. 2 is a partial front cross-sectional view as described above, and the pedestal part (frame) is referred to as a pedestal part (frame) in the entire description of the floating body. Instead, it is necessary to withstand a certain amount of strength, and it may be an aggregate such as stainless steel, and the entire FRP system has strength as a chassis, and the floating ring of the floating body 4 FIG. 2 shows a cross section of a part attached to a part of the aggregate such as a part of stainless steel.

Next, FIG. 3 is a partial side view of the floating body 4. As shown in the figure, the rotary propulsion unit 3 is located on the side of the wheel portion (tire), so that only a part of the rotary propulsion unit 3 is convex and has a deformed shape. However, this is arbitrary (see FIG. 2 as well). Therefore, the actual design can be determined by comprehensively considering material cost, processing cost, design, function, and the like.

Next, FIG. 4 is a partial cross-sectional explanatory view of the pin clutch of the lock pin 30 of the rotary connecting portion 2. As shown in FIG. 3, when the levitation body 4 has wheels 5 and runs on the ground for a long time, if the driving force is not transmitted to the rotary thruster by removing the pin on the pin clutch's nuversal side, the fuel consumption of the vehicle, etc. The sound is quiet while driving.

Next, FIG. 5 is a partial front explanatory view of the tire attachment. As shown in the figure, as described above, the rotary connecting portion 2 is not attached to the hole of the wheel 9 but the rotary connecting portion mounting hole 19 of the plate portion 16 of the tire attachment shown in FIG. It is connected using 17 bolts or the like. And this is to attach a plurality of arm-like hooks to the tire (2 to 4 are good, 3 is the best), and to the hole portion 17 of the plate portion as described in detail above, the rotary connecting portion 2 are connected. This is because it does not damage the wheels, etc., and it is very quick to attach and detach. Also, when running on sandy shores and entering the sea etc., it has a great effect of preventing slip (15 arms) at the tire arm. In addition, since the slide portion 21 is provided, the vehicle can travel very smoothly on uneven roads. Also, because of the slide portion 21, the connection between the rotary connecting portion 2 and the plate portion 16 of the tire attachment of FIG. 5 is always true. It is connected in a single line (Even if there is eccentricity due to the gravity of the tire car, this slide part always keeps the true center point) In addition, rubber etc. is put on the back of the plate part so as not to damage the wheel It's also good.

FIG. 6 is a plan view of a screw 29 propulsion unit using a bevel gear 18 in place of the rotary propulsion unit 3, and is an explanatory plan view of a mounting portion of the bevel gear of the floating body 4. The way of transmitting the drive source is the same as that of the rotary propulsion unit 3.

FIG. 7 is an explanatory plan view of a mounting portion of a flexible wire for a floating body using a flexible wire 25 in place of the bevel gear 18. Incidentally, in order to float the car, etc. If 1t as shown in FIG. 2 because required water content of the volume of the floating member of 1M ^3, since divided into left and right in one is required at a time 0.5M ^3. Of course, the weight of the levitating body and the person of the car will be plus α, so it is necessary to think about it and calculate it and make it a little larger.

FIG. 8 is an explanatory partial plan view of a bearing pedestal (frame) on which the bearing 13 slides and rotates. The bearing slide portion 33 is formed by making an arc-shaped cut so that the bearings 13 and 13 can be slidably rotated on the center of the front wheel X (the center of steering rotation of the front wheel) and the X as a fulcrum. Two arc arrows are shown. Of course, since the fulcrum is the front wheel center fulcrum 34 of the X mark, the curve line of the arc may be shorter as it is closer to the front wheel center 34. Therefore, the bearing portion slides in a predetermined range on the circular arc with the front wheel center fulcrum 34 as a fulcrum, and the pedestal (frame), and the direction of draining the impeller 7 changes according to the direction of the front wheel. Then, springs 14 as tensioning means are mounted on both sides of the bearing 13 to return to the center. In the case where the direction of the blade (car) 7 is not changed according to the direction of the front wheel, a steering function that rotates according to the steering wheel operation of the automobile is separately provided.
This means that the floating body moves to the left and right according to the direction of the tire 10 and changes its direction. Of course, it takes a lot of resistance, but this is also one method. Of course, at this time, it is desirable that the floating body 4 is separated for the front and rear tires.

There is also a method in which the floating bodies on both sides of the automobile are disassembled into a front wheel body and a rear wheel body, and the two bodies are connected.

Moreover, a position adjustment slide part is attached to the base part (frame) part of the bearing part 13 of the rotary shaft of the rear wheel part of the floating body. But there is a way to leave it out. This has been explained in the above [0029] with the bearing slide portion 33 for the front wheel. For example, when making a large number of water traveling devices for this car in a certain car model, Since the span (the length of the center point of the inner diameter of the tire) is constant (because of the same vehicle), there is no need to adjust the mounting span to the tire, so the cost is reduced. Of course, the slide groove is different from the front wheel, and the tire is fixed and the circular arc is not fixed. Therefore, the bearing 13 that holds the rotary connecting portion 2 and the shaft portion connected to the pedestal portion (frame portion) in a straight line is provided on the shaft. On the other hand, a slide groove is provided so as to be a right angle.

There is also a method of using the universal joint 1 and / or the spline for the rotary connecting portion.

There is also a method in which only the rotary connection (part) to the tire is used without connecting the floating bodies on both sides. As described above, this method is also available when the weight of the vehicle body is light or when the overall balance (vehicle body relation, floating body, other situations, etc.) is good.

Moreover, 6 clutches (FIG. 4 is an example of a pin clutch) are used for the said rotary connection part 2, and it is used when the drive source from a tire is not made to conduct to the rotary propulsion device 3 temporarily, etc., It is convenient to use when running on land for a certain time.

Also, when the levitation body 4 is provided with wheels 5 and the levitation body 4 is mounted on a tire and then travels on land for a certain period of time, the gravity of the levitation body 4 is reduced to an axle (bearings such as tire parts and rotary propulsion units) It is because it does not give to.

Moreover, it is also possible to carry out by providing a screw 29 propelling device using the shaft or flexible wire 25 using the bevel gear 18 of the rotary shaft portion (26) of the floating body 4 or the flexible wire 25 in the rotary connecting portion 2. It is possible enough. At this time, waves, sounds, etc. are quiet, and the head is used to design the floating body 4 to some extent, but it is the most ideal water traveling device. The reason is considered to be that automobile elements will be 50% or less and boat elements will be 50% or more.

In addition, on the pedestal provided near the inner diameter of the tire outer surface of the arm and the arm to be attached to the tire in contact with the inner side surface, the grounding surface and the outer side surface of the tire on the rotary connecting portion, A plurality of tire fittings provided on the pedestal portion with slide portions that hold the arms slidable in the radial direction are mounted on the tire, and the rotary connecting portion is connected to each pedestal of the plurality of tire fittings. It is also possible to do. This is composed of the arm 15, tire 10, slide part 21, plate part 16, lock nut 24 part, etc., and is more realized by this development, which seems to be very beneficial as described above. The invention was born and this invention was born.

In addition to the slide part, it is a tire mounting tool that adjusts the pressure of the arm against the tire according to the degree of tire reduction, and can be implemented with a pressure adjustment function, which includes drive loss and the like. It is very good because it becomes less.

In addition, by attaching rubber and springs as elastic bodies or both of them (combined use) to the slide part of the tire fitting, the sound and vibration from the drive source can be softened, and the drive loss can be reduced. Etc. can be reduced.

In addition, when the arm 15 is provided with a free joint, sound, vibration, etc., and ease of mounting on various tires and traveling properties are improved particularly when traveling on land.

Further, when the rubber free spring 1 or both of them are attached to the free joint of the arm as an elastic body, the above effects can be obtained as described in the above (0040). The free joint is 1 and has the same meaning as the universal joint. This is to reduce the sound, vibration, etc., and to increase the rice span, and to obtain smooth vibration and operation (land, water).
[Other changes and additions]

There are various types of universal joints (free joints, but their use is optional), (two-dimensional, three-dimensional), and multiple use is also possible for the connecting part, and 32 step spacers are 8 is attached to the floating body connecting bar, which has a jack-shaped contact surface part such as a V-shaped upper part in a strong part such as a step part under the door of the vehicle body, and can adjust the height freely Tell the body weight to the levitating body. The levitation body may be FRP, blown polystyrene, or rubber boat type.

As an application example of the present invention, when working on the surface of water at sea, lakes, rivers, ponds, etc., as described above, attach this device directly from home (when operating on land for a little longer time) (It can be downsized by bending the floating body 90 degrees using a clutch. Of course, it can be bent at the universal joint part.) You can go to the shore and go to the work place as it is. For example, you can do various checks in the sea, etc. It can also be used for leisure purposes, especially for disaster prevention, in case of sudden floods, and can save lives.
