| 1. | Variant 1 The nauticbike is the unique invention, belonging to the group of the floating objects for recreation and entertainment on the water. This invention can be made in favourable carrying capacity and variants. This variant is determinate by the fact that the invention consists from the bearing construction that is linking the bearable floating cushions, the motive mechanism and driving mechanism, all in one complex unit, so that bearable cushions, made of polyurethane foam, can hold the nauticbike on the surface. The motive mechanism enables the power transfer, from paddles, over the suppressing levers, chain wheel and Gal's chain on rotation of blade turbine, grabbing the water and by suppress power moves the nauticbike. Driving the nauticbike is possible over the steering mechanism that consists of governable levers, shaft bearings in supporting construction and fork, connected by bolts on anterior cushion, so you can twist it in leftright direction, in purpose to drive the nauticbike. |
| 2. | Variant 2 The nauticbike regarding the Patent Appeal 1 and Variant 1. This variant is determinate by the fact that bearable floating cushions are of the air type, with possibility to inflate or deflate, instead of polyurethane foam. |
| 3. | Variant 3 The nauticbike regarding the Patent Appeal 1 and Variant 1 or 2. This variant is determinate by the fact that propeller is moving the bike (instead of bladeturbine) because the motive force affects to the propeller over the transferring mechanism and over the revolution reduction. |
| 4. | Variant 4 The nauticbike regarding the Patent Appeal 1 and Variant 1,2 or 3. This variant is determinate by the fact that legs motive power is replaced by electric motor with DC current from the battery. The electric motor power is acting over the transmitter and over the reduction on turbine or propeller. |
Technical problems This invention resolves the problem of entertainment, recreation and sport on sea, lake and river. By developing the tourism, the needs for new kinds of entertainment and recreation are every day larger. The existing floating objects can not satisfy every day larger pretensions of tourists and other fans of sport and recreation. The nauticbike, because of various possibility of construction, in more then one shape or size, should be broadly applied in the sector of recreational tourism. After the application in the section of recreational sports, in the brief time we can expect its application in the competitive sports.
Technical state This invention is unique in the world. There is not known that any of floating objects was made in such technical manner. The most similar floating object until now was presented under the name"Surfbike". This floating object is of monohull type, driving by legs and steering over the helm's plate. The above mentioned floating object is too big, too heavy, with poor manoeuvring possibilities and made in only one shape, so we can say, it is not suitable for use on beach and for the mass recreation.
The essence of invention The bicycle, as a sort of vehicle suitable for use on land, became very useful, socially established and attractive. The nauticbike is invented on this basis, with intention to be useful in the very same way, established and attractive object on the water. This floating object is ecologically very acceptable because it is not causing any pollution. The construction of the object is made very carefully, so it cannot causing injuries nor for driver or swimmers. The floating object can't sink doesn't matter the position. Regarding the question of health, driving the bicycle is very useful. Also, driving the bicycle will be also useful and safe because of lack of vibrations, shaving or eventual falling off. You are not driving in crowded road traffic, so there is no dust, gases, tensions or stress because of possible car accidents. You can drive the nauticbike easily so you can rest mentally and be active physically.
Short descrintion of drawings The accompanying drawings are visually helpful in explanation of elementary principles of invention. These drawings are made in proportion of 1 : 10. Because of length of the floating object, the upper and the lateral projection are made from two parts, to be corespondent to format A4.
Drawing 1 is showing the front part of object, the view from the upper side ; Drawing 2 is showing the backside of object, the view from upper side ; Drawing 3 is showing object looking from backside ; Drawing 4 is showing the front part of the lateral projection; Drawing 5 is showing the rear part of the lateral projection; Description of drawings, in detaib This invention is floating object, which construction is divided in four basic complex units. We present the detailed describe of invention by following these four units. The basic complex units are : - The complex unit of the bearing construction; - The complex unit of the bearable floating cushions; - The complex unit of the motive mechanism ; - The complex unit of the steering mechanism ; The complex unit of the bearing construction-is made from steel profiles (rounded tubes and flat steel profiles). The bearing construction consists of 20 parts integrated in one unit by welding. It is connected with other units by bolts.
The complex unit of the bearable floating cushions-Dimensions of the object are based on"Archimedes law"and correspond to the favourable carrying capacity. The construction consists of three bearable floating cushions : two posterior, which are stable and one anterior which is movable, bearable and in purpose of steering. The bearable floating cushions consist of the cushion carrier, the cushion mantle, the cushion fulfilment and the connecting armature to the bearing construction unit. The complex unit of the bearable floating cushion consists of 23 parts connected between them with bolts.
The complex unit of the motive mechanism-is made on the basis of the bicycle motive mechanism. The motive force produced by legs is transferred over suppressing levers, driving shaft, bearings and chain wheel and Gal's chain to the power turbine that, by grabbing and suppressing the water, makes the floating object to move. The unit of the motive mechanism consists of 80 parts connected between them and with the bearing construction by bolts.
The complex unit of the steering mechanism-is also made on the basis of the bicycle steering mechanism. Driving the floating object is possible by handlebars, the shaft, bearings and the transferring lever (fork) to the anterior bearable and floating cushion, which is able, by its twisting, to conduct the floating object in desirable direction. The unit of steering mechanism consists of 12 parts, connected to the bearing construction by the shaft bearings and to the governing cushion by bolts.
Under the governable levers, on the shaft, we have built-in an auxiliary cushion, in purpose to prevent over- turning of the object for 180°, but to hold the over-turned object on the surface under angle of 100°. In such way, it is possible to turn back the object in the vertical position. Normally, you are driving the nauticbike in sitting position. The saddle is identical to the road bicycle saddle with possibility of height regulation. The size (dimensions) of the nauticbike depends on carrying capacity. The dimensions for carrying capacity of 50-100 kg are : 3,0 x 1, 2 x 1,2 m.
Regarding the purpose and conditions of exploitation, it is possible to organise production in few variants: Variant the bearable cushions-of polyurethane foam or air cushions with possibility of inflation/deflation.
Variant ! D The motive mechanism-with the transmitting mechanism and bladed turbine, or with the transmitting mechanism, the reduction number of revolutions and propeller instead turbine.
Variant The motive power of the floating object-by legs, over the transmitting mechanism, or by electric motor with DC from the battery.
The mode of invention's application The nauticbike as an invention belongs to the group of floating objects intended for recreation, entertainment and sport. The lack of floating objects for various purposes, development of tourism, sports and recreation on the water, is the guarantee for the successful and continuous application of this invention.
The nauticbike brings some new and specific events in sector of recreation, entertainment and sports on the water, regarding to already existing floating objects as sandolina boats, paddle boats, surfboards and various inflatable boats.
This invention is possible to produce very economically. The raw material is not expensive ; part's production is not complicated, and subsequently not expensive. Dimensions of the floating object, as well as its weight, are relatively small, so the object is suitable for transportation on every car baggage carrier. The units of nauticbike can be easily assembled and disassembled.
