Description

BOAT WITH MOVABLE ENGINE MOUNT

TECHNICAL FIELD AND INDUSTRIAL APPLICABILITY

OF THE INVENTION

[0001 ] This invention relates to a boat having an element for relieving weight of an outboard engine from boat while engine still functions to push boat forward.

BACKGROUND OF THE INVENTION

[0002] It is great ambition of people around the world to have fast transportation while capable of carrying considerable weight along, yet should use the least fuel possible. So many different kinds of vehicle were constructed like that of Glasby (U.S. 1,823,735), Verdi (U.S. 3,207,120) and Thompson (U.S. 3,522,785). Yet these have never been brought to practice due to certain technical limitation. A 'Smart Boat' of Mongkol Jesadanont et al. (U.S. Patent No. 6,892,665), is incredible for its speed and reduction of fuel used. When an element of the present invention has been installed to the boat, it would help reducing the size of flaps mounted to the boat and allow moving of the boat above water surface more rapidly and efficiently. SUMMARY OF THE INVENTION

[0003] A boat with an element is invented to move above water surface having only its propeller rotates under the water to drive it forward with high speed continuously where element is for relieving weight of an outboard engine from a boat to be loaded onto water through a ski structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0005] A smart boat is invented that can move above water surface having two flaps at the anterior and two flaps at the posterior on the left and the right sides of the boat at any proper position in the boat. Flaps are controllable to move

S pivotally at any angle about a hinge which helps keeping boat at an appropriate . level above water aerodynamically. An element is installed to minimize weight of engine carried by boat. This invented element for relieving weight of an engine from a boat must be only of outboard engine type. [0006] AU types of engine, outboard or inboard must be first modified before0 use. There are three kinds of engine to be modified:

1. Outboard Engine

As FIG. 1, engine 20 whose stem 22 is extended by part 23 and becomes engine 25 as in FIG. 2

2. Water Jet Engine, an inboard engine is modified. 5 FIG.3, water jet engine 30 is modified to become outboard jet engine 35 as in FIG. 4 transmitting power through gear units 36 and 37 to rotate propeller 31.

3. Inboard Engine 40, normally inside a boat as in FIG. 5 is modified to outboard engine 42 as shown in FIG. 6. 0 [0007] The difference between engine 42 and engine 25 and 35 is that engines 25 and 35 use gasoline, they are of lighter weight and is not greater than 300 horsepower (hp) and not mofe than 300 kilogram.

Engine 42 is of diesel type with low speed. Steps of assembling are as follows: [0008] Element 52 of the present invention as shown in FIG. 7 comprises of 2 main parts as follows:

1. Part I : mounted to rear part of a boat. This part is stationary composed of 2 rectangular^' metal tubes 54, 2 steel plates 108, a thick steel plate 60, a thick steel plate 62, first hydraulic 92 and second hydraulic 110. The weight of part I all is carried by boat at its stern through steel plates 108.

2. Part II : for mounting of engine. This part moves vertically up and down relative to part I and is composed of two rectangular steel shafts 56 and all other components fixed to two steel shafts. Part II is carried by boat if there is hydraulic fluid and pressure in hydraulic 92.

[0009] As shown in FIG. 7, element 52 comprises two rectangular tubes 54 having in each tube a rectangular shaft 56 where shaft 56 can move up and down vertically in tube 54. The upper portion of the two rectangular shafts 56 connected to each other with steel plate 58. Upper part of modified engine is mounted to this plate 58.

Thick plate 60 connects the upper part of tube 54, while thick plate 62 connects their lower ends.

The lower ends of two shafts 56 are connected through steel rod 64 whose two ends 66 extended sidewise of shaft 56 pass through cavities 70 of thick plates 68 to allow free rotation of plates 68 about ends 66.

[0010] Ski 80 is mounted to the lower ends of steel plates 68.

Switch 82 is mounted to front curving end of ski 80.

Switch 84 is mounted to rear straight end of ski 80.

Switch 85 is mounted to lowest point under boat hull at its rear end. [0011] Switches 82, 84 and 85 function when immerse under water to turn on light bulbs 121, 122 and 123, respectively, on the control panel 120 as in FIG. 8 to light up. When these switches are not in water, these light bulbs turn off.

[0012] Rings 86 are fixed at posterior ends both sides of ski 80. Rings 88 are fixed at lower ends of both shafts 56 above plates 68.

When shafts 56 move up, rings 88 move into groove 90 of tubes 54.

[0013] Hydraulic 92 locates between plates 60 and 62 by hanging from mid point of plate 60 through hook 94.

Hook 96 of stem 98 holds rod 64 at its midpoint where stem 98 passes through cavity 63 of plate 62.

[0014] Ski 80 is pushed or pulled to a desired angle by hydraulics 102 connecting between rings 86 located sidewise at the posterior of the ski and rings

88 at shafts 56 just above plate 68.

[0015] Steel plates 104 are upright at rear end of boat 50 on each side. Steel rod 106 connects two plates 108.

Each steel plate 108 is mounted to tube 54 on each side and turns pivotally around rod 106 having its ends pass through cavities 107 of plates 104.

[0016] Hydraulic 110 connects deck at position 112 and ring 1 16 of stem

114 mounted to cavity 61 of plate 60. [0017] When driver presses a switch to pump hydraulic fluid into the hydraulic, length of stem 114 varies and is under control of hydraulic 110.

[0018] This hydraulic 92 is key element in the present invention which functions to transfer total weight of engine from boat to load on water. When there is fluid in hydraulic 92, there will be pressure within hydraulic which causes the hydraulic to connect part II tightly to part I. In this situation, boat carries total weight of engine and element 52 through stem 98 where hook 96 of part I holds weight of part II and engine while plates 108 is the part that carries element 52 and total weight of engine. Thus, boat carries total weight of engine. That is, part II is fixed tightly to part I at the point hook 96 holds rod 64 when there is fluid and pressure in hydraulic 92. Once there is no fluid in hydraulic 92, part II is then able to move freely up and down relative to part I.

[0019] Element 52 is thus composed of two main components. While there is hydraulic fluid and pressure in hydraulic cylinder, second part is held tightly and stationary to first part. But when fluid is exhausted from the hydraulic cylinder, there is then no force thus allowing second part to move freely up and down vertically relative to first part. In such latter situation, rectangular shafts of second part move freely up and down inside rectangular tubes of first part. The total weight of engine is then loaded onto ski structure of second part and while boat is moving fast, engine weight is thus loaded to water and boat needs not carry engine weight any further just like a man is skiing as in FIG. 9. Yet, engine still continuously pushes boat forward.

[0020] FIG.10 shows engine 42 of diesel type with lower revolution installed to boat 50 and no flaps since they are of no use. [0021 ] According to FIGs. 11 -13, a smart outboard boat is constructed and installed this element invented. This allows moving of boat better and in shorter time and helps reducing dimension of flaps, engine used should be engine 25 or 35 (FIG. 12 and FIG.13, respectively) which are of faster type to be installed onto plate 58 in addition to installing flaps 170 and flaps 172 at the anterior and posterior, respectively, on both sides of boat. These flaps are to pivotally move by hydraulic system through a control knob at the control panel. Flaps 170 turn pivotally up to have wind presses front of boat down to prevent turning of boat upside down. [0022] If stem 114 is shortened, an element 52 moves to lie down onto the deck as in FIG. 14 to keep engine onto boat deck while boat is anchored. [0023] As shown in FIG.11 , switches along a vertical rod 149 activate the light bulbs at the control panel 120 to light up in a following manner:

At a height >0 - 0.5 meter, switches 154, 152 and 150 under water, light bulbs 160, 158 and 156 light up, respectively;

At a height 0.5 — <1 meter, switches 154 and 152 under water, light bulbs 160 and 158 light up;

At a height 1 - <1.5 meter, only switch 154 under water, only light bulb 160 lights up. [0024] Any electronics or any systems such as sonar system capable of indicating the level of bottom of boat above water can alternatively be used. [0025] A smart boat is invented having an element to help minimize load of an engine. This is an element to transfer total weight of engine from boat to be carried by ski which was loaded to stream of water moving underneath the ski.
