Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water walking apparatus which is capable of moving near the water surface by human power. Conventionally,
There are various types of playground equipment such as beach balls, floats, air mats, rubber boats, and water skis for swimming in the sea, and in recent years, water bikes and the like have begun to spread. The present invention was also invented as a kind of play equipment for sea bathing and the like. The structure of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the whole of the present invention. Reference numerals 1 and 1 denote both left and right main bodies, 2 lift wings, 3 support posts, 4 handles 5 and 5. Is a left and right flapping wing, and 6, 6 are both left and right fixed bands. The size of the main body 1 is about 1.3 to 1.5 m in length, the width is about 35 to 40 cm, and the thickness is an appropriate thickness depending on the material at the time of processing such as a veneer plate and a plastic plate. The size of the lifting wings 2 is about 20 cm in length and about 35 cm in width. Agitating wings 5 are each 30 vertical
It seems that the cm position and the horizontal position are the same as those of the main body 1. FIG. 2 is an exploded view of the main body 1. Explaining the structure of each detail, both bearings 7, 7 formed of pipes or the like are provided at the front end portions of the both main bodies 1, 1. A convex portion 8 is provided in the middle of the rear side of the elevating blade 2, and both shafts 9, 9 parallel to the elevating blade 2 are provided at both left and right ends thereof. Both bearings 7, 7 provided on both main bodies 1, 1 on this shaft 9
After inserting, the ends of both shafts 9, 9 are fixed with nuts, split pins, clips, etc., and both main bodies 1, 1 and the lifting blade 2 are rotatably fixed. The lower end of the pillar 3 having the handle 4 on the upper portion is fixed to the convex portion 8. The elevating blade 2 and the support column 3 are integrated, and by moving the handle 4 back and forth, the elevating blade 2 becomes an elevation angle or an attachment angle. That is, with the elevating wings 2 horizontal, the support columns 3 are tilted rearward to some extent, and if the handle 4 is pulled forward (rearward) from that position, the elevating wings 2 are at an elevation angle, and conversely if they are pushed forward, they are attached. It becomes a corner. Incidentally, it is considered appropriate that the connecting portion between the column 3 and the convex portion 8 has a detachable structure in order to facilitate carrying. 3 is an enlarged partial side view of the rear portion of the main body 1, a U-shaped tube 10 having a part (rear portion) cut out is fixed to the rear side of the main body 1. On the other hand, a cylindrical member 11 slightly smaller than the inner diameter of the U-shaped tube 10 is provided on the front side of the fan blade 5, and the cylindrical member 11 is slid from the side surface of the U-shaped tube 10 and fitted therein. Similar to the above, the conventional technique is used to prevent the flapping blades 5 from falling off from the side surface. Then, the legs are inserted into the fixing band 6 provided in the middle of the rear portion of the upper surface of the main body 1, and the main body 1 is alternately moved up and down in the water. At that time, the flapping wings 5 are bent in the opposite direction to the main body 1, The upper and lower tip portions 12 of the character tube 10 are struck to prevent further bending. It seems appropriate to bend up and down about 20 degrees above and below. If the main body 1 is pulled up by the leg force, the slanting blades 5 move downward and hit the lower end portion 12 of the U-shaped tube 10 and stand still. This is done in an instant, and the flapping wing 5 is pulled up while being fixed downward. By this action, the water flow on the upper surface of the fan blades 5 is exhausted rearward, and conversely, the water flow when the main body 1 is stepped down is exhausted rearward on the lower surface of the fan blades 5, and the two main bodies 1, 1 move alternately up and down. Also, the main body 1 moves forward due to the flapping action of the bifurcating wings 5 and 5 interlocking with it. FIG. 4 shows another example of the structure of the fan blades, in which the fan blades 5a are made of a material such as a flexible rubber plate or a soft synthetic resin plate and fixed to the rear side of the main body 1a. When the main body 1a thus configured is moved up and down,
As shown by the imaginary line, the flapping wings 5a are turned upside down in the opposite direction, and the body 1a moves forward just like when a human swims with his flippers or when a fish shakes its tail and moves forward. .. The weight of the entire walking device should be the same as or slightly lighter than that of water. Then, the weight distribution is such that the front half of the device is slightly heavy and the rear half is slightly light. Further, the upper half of the support column 3 and the handle 4 portion have a floating structure (for example, foamed polystyrene is applied to this portion and the outside is covered with synthetic resin or the like, or this portion is made of hollow plastic or the like). When such a device is put in water, the front half of the device becomes the lowest position and the rear half floats up and down, and the upper part of the column 3 and the handle 4 part are projected to the surface of the water. .. The operator depresses the rear half with a hand or a foot, and inserts his foot into the fixed belt 6 and alternately performs a stepping motion to move forward by the tilting device. When the handle 4 is pulled toward you, the interlocking lift blades 2 face upward and the entire device floats up to near the water surface. When the handle 4 is pushed forward, the lift blades 2 face downward and begin diving. When turning, the handle 4 and the driver's body should be tilted in the direction of turning. Needless to say, if the stepping motion is weak, it is natural that even if the elevating blade 2 is directed upward, it does not float near the water surface. When the left and right main bodies can be alternately moved in water, it requires less force when stepping down, but requires considerable force when pulling up. In FIG. 5, the main body is devised to eliminate the drawback. That is, only the edge of the main body 1b is left and the net plate 13 is attached to that portion. (It seems that the mesh size of 7 mm square is appropriate). FIG. 6 shows the right main body 1b of FIG. 5 turned upside down.
Fixing members 14 are provided on the lower portion (the upper portion in FIG. 6) of the mesh plate 13 at appropriate equal intervals, and further, a valve plate 15 having one side fixed to the lower surface of the fixing member 14 is provided on the lower portion thereof. Figure 7
5A is a partially enlarged cross-sectional view of FIG. 5A-A, the main body 1b is cut inward by the thickness of the mesh plate 13 and the fixing member 14, and after the mesh plate 13 is fitted, both ends of the fixing member 14 are fixed to the main body 1b. It adheres to the surface and is considered for practical and aesthetic purposes. The distance between the fixing members 14 is about 30 to 35 mm, and the fixing members 14 are the same.
The length of the valve plate 15 fixedly attached to the lower surface of is about 35 to 40 mm seems to be appropriate (a length sufficient to reach the adjacent fixing member 14 as shown by an imaginary line). With such a structure of the main body 1b, water from the upper surface of the main body 1b can pass through without difficulty, but water from the lower surface cannot pass through. With this valve mechanism, pulling up (upward movement) of the main body 1b becomes very light. Valve plate 1
5 is a thin and durable cloth, vinyl cloth, etc., and it seems appropriate that it will not be damaged or damaged even if it is bent many times. The first
As in the figure, the main body 1b is also provided with a fixing band at the same position, and a considerable force is likely to be applied during vertical movement, so it is necessary to take measures such as reinforcement. 8 and 9 show the main body 1b
8 is a schematic diagram of the operation of FIG. 8, showing a state in which the main body 1b is moved upward (in the direction of the arrow) by leg force,
Water passes through the mesh plate 13 and the downwardly facing valve plate 15 without difficulty. At that time, the slanting blade 5b is directed downward, and the water flow on the upper surface of the blade 5b flows rearward (in the direction of the bent arrow). On the contrary, FIG. 9 shows the state where the main body 1b is stepped down in the direction of the arrow and the valve plate 15
Is laterally rearward and closely contacts the mesh plate 13, so that water from the lower surface cannot pass through. Then, the slanting wing 5b is directed upward, and the water flow on the lower surface of the wing 5b flows in the direction of the broken arrow, and the walking device is advanced by repeatedly moving up and down the two main bodies 1b, 1b. By using the main body 1b with such a valve mechanism, it is possible to reduce the leg force when pulling up and to perform a quick stepping motion. The valve plate 15 is made of cloth, but as another embodiment, it may be made of a solid resin plate or steel (aluminum plate, stainless plate). In that case, the bent portion of the valve plate has a hinge structure, or as shown in FIG. 10, the fixing member 14b is a round bar and one end of the valve plate 15b is rotatably wound around the fixing member 14b ( As shown by the imaginary line, the length of the valve plate 15b is set such that it can reach the adjacent fixing member 14b). With such a valve mechanism, the mesh plate 13 is not necessary, and it is considered that the pull-up leg force is slightly relaxed (in this structure, a different material is used for fixing the leg fixing band). FIG. 11 is more practical than the main bodies 1 and 1b, and pursues further reduction of the stepping motion. Body 1
A valve mechanism similar to the main body 1b is provided on the entire central portion of c, and levitation members 16 of appropriate sizes are provided on both rear edges of the upper surface of the main body 1c (generally, the length is the main body 1).
It is considered that the rear half of c is about the same width as the edge width of the main body 1c, and the height is about 5 to 10 cm. The levitation material 16 has a hollow structure or has a floating body structure filled with styrofoam or the like. By providing the floating member 16, the pulling leg force of the main body 1c is further reduced as compared with the main body 1b. Side plates 17 are provided on substantially the entire lower edges of the main body 1c. FIG. 12 shows the main body 1c of FIG.
The bottom net plate 18 is fixed to the lower parts (upper part in FIG. 12) of the both side plates 17, 17. The side plate 17 prevents the flow of water that tends to flow to the side surface of the body 1c when the body 1c is moved downward, that is, when it is stepped down (to try to escape), so that it can be easily floated with a small stepping leg force. Be done. Further, the bottom net plate 18 and the side plate 17 are also intended to protect the valve mechanism when the apparatus is placed on a sandy beach or stored in a car trunk or the like and carried. That is, as shown in FIG. 13, when the main body 1c is placed on the ground or the like, the valve plate 15c faces downward. In order to prevent damage to the valve plate 15c facing downward, the height of the side plate 17 is set slightly higher than that of the hanging valve plate 15c.
A bottom net plate 18 is provided to protect the lower part of the whole c. It is considered that the bottom mesh plate 18 may have a larger mesh than the mesh plate 13. Incidentally, similarly to the above, the main body 1c is also provided with a fixing band reinforced by something at the same position.
In order to enhance the floating effect of the main body 1c, it is conceivable that the side plate 17 has a hollow structure from the middle to the rear part. As described above, the reason why only the rear part from the middle of the main body 1c is to be floated up is explained. When riding this device, the main body 1c is floated to a place above the depth of water in the chest or shoulders and then the ride is performed. However, if the entire main body 1c is lightened, the entire apparatus floats above the water surface, making it very difficult to get on. Even if you get on well, you have to keep pressing the handle with your upper body and your hands at all times, which results in 100% unsatisfactory foot movement of the lower body. FIG. 14 shows a state where the present apparatus is floated in water. The front half of the apparatus, that is,
Since the front half of the main body 1c and the middle and lower parts of the lift blades 2c and the columns 3c are made heavier than the specific gravity 1, they are submerged in water.
On the other hand, in the rear half of the main body 1c, the levitation member 16 and, in some cases, part of the side plate 17 are also hollow so that they are projected to a certain extent on the water surface (the flapping wing 5c has a specific gravity of 1 and is thin and durable). Use different materials). If the handle 4c has a floating structure similar to that described above, it will be in a state of being projected on the water surface like the rear half of the device. When riding this device, after pulling down the part of the main body 1c that has jumped out above the water surface by hand, further step down with your foot to put your foot in the fixed belt (not visible in the drawing).
When the handle 4c is held by hand, the preparation is completed and FIG. 15 shows the state. With such a structure of the main body 1c, the pulling leg force is less than that of the main body 1 or 1b, and a long walk on the water is possible. The valve plate 1 can be placed on the beach after use or carried in a car trunk or the like.
This device seems to be the most practical because 5c is protected. It is also conceivable to provide a levitation material also on the rear half of the main body 1 or 1b. It is considered that styrene foam or a levitation material such as a hollow structure can be provided on the entire surface of the latter half of the main body 1 to have a considerable levitation effect.
It is essential that the weight distribution be as shown in FIG. As the operator becomes more proficient in manipulating the device, he / she can freely walk around by suddenly turning, suddenly ascending, and suddenly diving by moving the center of gravity of the operator or operating the steering wheel. When it further rises, the lift blade becomes unnecessary, and the handle can be lifted and pushed to adjust its height so that it can ascend and dive. Therefore, it is considered appropriate to make the lift blade detachable. The present invention is as described above, and it is believed that the present invention will be widely used as a playground equipment in a sea bath or the like.
