Abstract

A vessel that is powered by the momentum created by rotating mass attached around a shaft. The shaft has ropes or cords attached at each end. When the first rope is pulled, the other rope at the opposing end is wound up ready to be pulled; subsequently, when the second rope is then pulled, the first rope is wound up again. The ropes are intended to be muscle powered by the user of the vessel. However, the ropes can be powered by a motor/engine. In a preferred embodiment, when the vessel is intended to be used on water, the back or rear of the vessel has a concave shape to stop the vessel going backwards. In another embodiment, the vessel has wheels with ratchets to prevent the board/vessel from going backwards; in this embodiment the vessel is intended to be used on land.

Description

DESCRIPTION

THIS DESCRIPTION RELATES TO A MOTOR FOR BOATS BOARDS RAFTS VESSELS AND VEHICLES

THE MOTORS NEED TO BE INCORPORATED IN A SPECIFICALLY CONSTRUCTED VESSEL OR BOARD

THE CORD MOTOR IS FOR MANUAL USE. A SHAFT IS SUSPENDED ON A FRAME IN BEARINGS AT EACH END THE SHAFT NEEDS TO BE % INCH TO 4 INCHES WIDE TOWARDS EACH END TO THE EXTENT OF ABOUT 2 INCHES. THE DIAMETER OF THE SHAFT TOWARDS THE CENTRE CAN BE SMALLER ONE CORD IS ATTACHED TO EACH END OF THE SHAFT IDEALLY ABOUT HALF WAY UP THE SIDE DIAMETER. ONE END IS WOUND AROUND THE SHAFT. THE CORDS ARE ENCOURAGED TO STAY AT EACH END BY MAKING **** **** A V OR U SHAPE THERE. THE CORD END THAT IS WOUND AROUND THE * SHAFT IS PULLED BY MUSCLE POWER OR OTHER MOTOR POWER AND THE * * SHAFT REVOLVES AND THE WEIGHTS THAT ARE ATTACHED STRONGLY TO IT AT RIGHT ANGLES ALSO REVOLVE. THE WEIGHTS ARE ATTACHED TOWARDS THE CENTRE OF THE SHAFT. ONCE THE CORD IS PULLED IT WILL * * ALSO WIND ON THE CORD AT THE OTHER END OF THE SHAFT. PUTTING * THAT IN POSITION TO BE PULLED NEXT ALTERNATIVE PULLS ON EITHER CORD SEPARATELY WILL PRODUCE MOTION BUT THERE NEEDS TO BE A * * * SLIGHT PAUSE WHEN MOVING FROM ONE CORD TO THE OTHER. * * * *** *

FOR USE ON A BOARD LIKE A SURF BOARD THE WEIGHTS NEED TO BE 1LB 80Z TO ABOUT 5LBS IN TOTAL 3LBS IS A GOOD WEIGHT FOR GOOD RESULTS. 6LBS VERY HARD TO PULL. 1LB WILL HARDLY WORK FOR LARGER VESSELS PETROL OIL GAS TYPE OF ENGINES ARE NEEDED WITH LARGER WEIGHTS. CONTINUOUS POWER IN ONE DIRECTION WORKS WELL. IT IS HELPFUL IF LARGER WEIGHTS ARE BALANCED BY AN OPPOSITE SMALLER WEIGHT WHEN HOUSING THE MOTOR ON SMALL FIBREGLASS WOOD OR FOAM BOARD IT NEEDS TO BE IN THE CENTRE MOSTLY BURIED TO GIVE A SMOOTH SURFACE TO THE TOP OF THE BOARD AND PREVENT INJURIES. SOME PROTRUSION IS ALRIGHT BUT IT NEEDS TO BE COVERED WITH * * * * RUBBER OR FOAM * * * * THE BOARD CAN BE WEDGE SHAPE FROM FRONT TO REAR MAINLY FOR * * ONE PERSON ABOUT 46 INCHES LONG BY 24 INCHES WIDE ABOUT 4 INCHES DEEP AT THE FRONT ABOUT 12 INCHES AT THE BACK DEPENDING ON SIZE * * OF MOTOR * * THE BACK NEEDS TO BE CONCAVE. IT IS PART OF THE MOTOR ABOUT 1FT BY 2FT TO PREVENT BACKWARDS PUSH * * * * * * * * * * A PLIABLE FIN CAN BE ADDED TO THE BACK IN A HORIZONTAL PLANE TO AID

PROPULSION

WHEN USING GOOD PLASTIC FOAM OR WOOD FOR THE BOARD THE BACK

CAN BE MADE IN CONCAVE SHAPE. THIS SHAPE STOPS THE VESSEL/BOARD GOING BACKWARDS AND THE PULL EXERTED BY THE WEIGHTS PULL IT FORWARDS NOT UPWARDS BECAUSE OF GRAVITY AND NOT DOWNWARDS BECAUSE THE SEA OR OTHER WATER IS THERE. PLEASE SEE MY PATENT GB2477789 AND APPLICATION GB 1014720.5. BACKS CAN BE HALF ROUND OR 2 HALF ROUNDS OR 3 HALF ROUNDS IN LINE OR VARIED. BACK CAN BE V SHAPED OR 3 SIDES OF A SQUARE ONE OF MORE THAN ONE A WOODEN BOARD IS USED TO MOUNT THE FRAME ON WHERE FOAM IS USED AND MAKE THE WHOLE STRUCTURE STRONG. THE BOARD IS INSERTED INTO THE BASE TO PROVIDE A FLAT AND SAFE SURFACE THE BOARD NEEDS TO BE APPROXIMATELY 8% INCHES WIDE AND 20 INCHES LONG AND TO 1 INCH THICK. TWO METAL OR ACRYLIC **** ** * * SUPPORTS ARE ATTACHED TO THE FLOOR BOARD OR OTHER MATERIAL EG * NYLON. THE SUPPORTS HAVE BEARINGS AT THE TOP END TO SUPPORT * * THE SHAFT AND ALLOW IT TO REVCLVE * THE FLOOR HAS BOLTS AT EACH CORNER WITH SHAFTS THAT GO UP * * THROUGH THE FOAM TO ABOUT 4 INCH BY 4 INCH WOODEN PLATFORMS.

* * THE BOLTS GO THROUGH THE PLATFORMS ARE BOLTED DOWN. THE ENDS

OF THE BOLTS NEED TO BE COVERED WITH RUBBER TAP WASHERS WILL

* * * WORK AND FOAM MAY BE COUNTERRSUNK INTO WOOD OR FOAM * * * * * * THE PULLING CORDS COME FROM THE SHAFT ALMOST IN PARALLEL AND GO THROUGH THE TOP OF THE HOUSING SPACE FOR THE MOTOR. THE TOP OF THE HOUSING MAY BE LEVEL WITH THE TOP OF THE BOARDS OR THERE MAY BE A BUMP IF NECESSARY TO MAKE WAY FOR THE SPINNING WEIGHTS

RATCHET WHEELS GOING FORWARDS ONLY MAY BE PLACED AT EACH CORNER OR JUST BACK OR JUST FRONT OF ANY OF THESE VEHICLESNESSELS TO ALLOW THEM TO GO ON LAND AS WELL AS WATER

A SIMPLE SHAPING OF THE FOAM CAN BE DONE BY SAW

ROPES CORD OR TAPES CAN BE PLACED AROUND THE EDGES OF THE BOARD TO PROVIDE HAND HOLDS

THE SHAPED BACK IS AN INTEGRAL PART OF THE WHOLE BOARD SURF BOARD CRAFT

TO START THE MOTOR THE CORDS CAN BE PULLED ALTERNATIVELY OVER A SMALL DISTANCE TO ROCK THE WEIGHT BACK AND FORTH

WHEN USING FOAM (RIDGED) IT SHOULD BE SOAKED UP TO ABOUT 2 * *

INCHES WHEN LYING FLAT IN THE WATER IT PROVIDES STABILITY AGAINST

* * ANY WIND * * * FULL SIZE WORKING BOARD AVAILABLE. THE DRIVING SHAFT CAN BE MADE OF METAL WOOD ACRYLIC OR HARD NYLON OR CARBON FIBRE. THE SHAFT IS PREVENTED FROM MOVING SIDEWAYS TO STOPS AT THE ENDS * * * *** *

Claims

CLAIMS1. A SHAFT IS ON A FRAME RESTING ON BEARINGS HELD IN PLACE BY STOPS TWO CORDS ARE ATTACHED TO THE SHAFT ONE AT EACH END ON THE SIDES OPPOSITE EACH OTHER. WEIGHTS ARE ATTACHED TO THE CENTRE OF THE SHAFT AT RIGHT ANGLES TO IT. THE ATTACHED CORDS DO NOT HAVE TO BE ABSOLUTELY OPPOSITE IN THE ATTACHMENT ONE CORD END IS WOUND AROUND THE END OF THE SHAFT. WHEN THIS CORD IS PULLED THE SHAFT GOES AROUND AND THE WEIGHTS GO AROUND. THE WEIGHTS PULL THE BOARD VEHICLE OR BOAT ALONG AND WINDS ON THE OTHER CORD AT THE OTHER END READY TO BE PULLED TO KEEP THE MOTION GOING AND SO ON THE WEIGHT NEEDS FOR A BOARD FOR ONE PERSON ARE IN THE RANGE 11/2LBS TO 6LBS PROBABLY ABOUT 3LBS ARE BEST DEPENDING ON THEIR STRENGTH AND SIZE * * * * * * * ** * * * ***
2. THE BACK OR REAR NEEDS TO BE CONCAVE IN SHAPE IN VARIOUS CONFIGURATIONS BUT ONLY ONE SHAPE ON ANY ONE BOAT VESSEL BOARD OR VEHICLE. THIS HELPS TO HOLD THE BOARD AND STOP IT GOING BACKWARDS AND IS INTEGRAL TO THE BOARD FUNCTIONING
3. WHEELS WITH RATCHETS TO STOP THE BOARD GOING BACKWARDS COULD BE ADDED FOR USE ON LAND * * * * * 0 * *** *
