Several embodiments of the invention are described hereunder referring to the attached drawings. Fig.l is a partially explanatory plan view of right-and-left floats that are attached to an automobile. The four-wheel drive car has four rotary screws (with blades) in the front and back, and in the right and left. Fig.2 is a partially explanatory cut-away view of a front side of the float, before a rotary joint section is linked with the wheel of the automobile. Fig3. is a partially explanatory side view of the float with the rotary screws drawn into the convex partially next to the wheel(cf. Fig.2). >Fig.4 is a partially cut-away view of a pin clutch at the rotary joint section. With the wheels on the floats as shown in Fig.3, it is economical to run a car on the ground for a long time, pulling pin out of the pin clutches on the sides of universal joints without conducting the drive to the rotary screws. Fig.5 is a partially explanatory drawing showing a front view of a tire-attachment. Without the rotary joint section being linke in a hole of the wheel, plural (up to 4), (3 for the best, generally) arm frames in a hooked state on the tire have the board the hole of which is linked with the rotary joint section, with a bolt. With the tire-attachments, the wheels, etc. are not damaged and the arm frames on the tires have slip -preventing effects on running a car from the sandy soil, etc. on the seashore, etc, to the sea, etc. The reverse sides of the boards may be attached with rubber, etc. not so as to have flaws, etc. on the wheel. Fig.6 is an explanatory plan view of a bevel gear with a propeller screw for the float, in place of the rotary screw. Fig.7 is an explanatory plan view of a flexible wire for the float, in place of the bevel gear. As shown in Fig.2, to make a one-tonnage car float, 1M3 is necessary as capacity of the floats in water, that is, 0.5 M3 is necessary as each capacity of the right-and-left floats in water. Fig.8 is a partially explanatory plan view of a frame with bearings which rotate partially in slide. With a fulcrum in the center of the front wheel, the bearings always on the parabolic circle with springs as measures for tension on both sides go back to the center (in the same way with weights).
Consequently, a person in a worksite on the surface of the water such as the sea, a lake, a river, a pond, etc. comes directly from his house with this device. (In case of driving on the ground for a little longer time, the floats may be vertically attached to the automobile at the universal joints, with the clutches). This invention will be used widely for laver manufacturers, etc. to work or check on the water, for leisure such as fishing, etc. and especially for disaster preventions such as saving lives in sudden floods, and the like.
OTHER MODIFICATIONS
A water-running device may have universal joints (free joints) among a variety of them (for three dimensions). The water-running device may further have a plurality of joint sections. Step spacers 32 with jack-shaped surfaces such as v-shaped surfaces, etc. on upper parts contacted with strong parts such as steps, etc. under doors of an automobile are attached to a link-bar 8 to adjust heights freely and transmit the weight of an automobile to each float. The floats "made of FRP (Fiber-reinforced plastics), Sjtyrofoam, etc. may have chasses as well as rubber raft-types. The floats must be put below the inner diameter in general.
The preferred embodiments described herein are illustrative and not restrictive, the scope of the invention being indicated in the appended claims and all variations that come within the meaning of the claims are intended to be embraced therein.
