Description:
WEIGHT BALANCED VESSEL WITH CABIN FOR PASSENGERS Technical field The invention is a vessel consisting of a float, a frame and a driving mechanism and it is to be used mostly for sports-and-leisure-time activities. In addition to the usual drive on the water surface reminding of a drive in a typical motorboat, it also enables the crew to make use of other functional regimes. These can be of an unusual variety with respect to the manifold possibilities owing to its constructional design.

Backrqround of the invention At present many vessels of various types are known, for instance various vessels with one or even more hulls, vessels made of materials which can float on the surface such as for example wood. We also know many vessels whose basic element is constituted by one or more floats.

Vessels of this kind are used for instance as the so-called pedal boats.

Large boats are based on the principle of a sliding weight which enables to maintain stability of the boats and its tilting when the waves are rather large. The hitherto known vessels are not based on the principle of the simultaneous transfer of both floats and weights, not even the vessels used for leisure-time activities.

Summarv of the invention The above-mentioned shortcomings are eliminated to a large extent by the vessel consisting of a frame, a float and a driving mechanism according to this invention. It is based on the principle that at least one float and one weight are attached to a frame in a sliding manner and/or rotating manner and also the cabin is attached to the frame and its deck and/or seats are placed on elements securing their stabilized position.

It is advantageous to provide the basic frame of the vessel with at least one bed and at least one guideway, and a swing frame is attached to the frame by means of a hub in a rotating manner and the cabin is attached to the free end of this swing frame and at least the weight is attached to the guideway in a sliding manner and at least one float is attached to the bed in a sliding manner.

The advantageous design has the basic frame with two beds and two linear guideways, a shaft is attached to the front part of the frame and at least one weight is attached to each of the two linear guideways in a siding manner and at least one float is attached to each bed in a sliding manner and the swing frame is attached to the shaft in a rotating manner by means of the hub and the cabin is attached to the free end of the swing frame.

Another advantageous design is constituted by the basic frame with the bed and guideway in a round shape.

The frame can be provided with a pair of front boat wings, and a pair of rear boat wings and a driving mechanism of the boat can be attached to the rear part of the frame.

It is advantageous to provide each bed with two skids attached in a sliding manner and float arms with the floats are attached to the skids by means of bearings in a rotating manner.

It is advantageous to attach three arms of the space lunette to the free end of the swing frame and it is in this lunette that the cabin is located and at the same time each arm of the lunette is provided with two self-turning wheels because of an antifriction attachment of the cabin and the swing frame can be attached to the cabin by means of a winch with a cable which is detachable.

Another advantageous design of the vessel consists of a cigar- shaped float inside of which there is built in the driving mechanism of the boat. A double frame is attached to the float in a rotating manner and a beam is attached to the upper free end of this double frame in a rotating manner and this beam is connected with the cabin in a rotating manner and a weight is attached to the bottom end of the frame. It is advantageous to attach a crank in a rotating manner between the beam and the cabin and this crank is provided with a driving mechanism for the rotation of the cabin. A precision gear is used to stabilize the turn by an angle of the beam with respect to the float and this gear consists of a fixed chain wheel attached to the float co-axially to the axis of rotation of the frame, a turning chain wheel connected to the beam and the chain of the position gear, and a weight is attached to the bottom arm of the frame only by means of a rider and a joint in a sliding manner.

Further advantageous design of the vessel has the frame connected with two floats and in the centre of the frame is a sleeve to which a turntable is attached in a sliding manner provided with two upper and two bottom brackets and the swing frame is attached to the upper bracket and the beam is attached to the free end of this frame in a rotating manner and connected to the cabin in a rotating manner and a weight is attached to the bottom bracket. It is advantageous to attach a crank in a rotating manner between the beam and the cabin and this crank is provided with a driving mechanism for the rotation of the cabin, a precision gear is used to stabilize the turn by an angle of the beam with respect to the float and this gear consists of a fixed chain wheel attached to the upper beam and the turning chain wheel connected with the beam and the chain of the position gear and a frame chain wheel is attached to the upper bracket in a rotating manner and a weight toothed wheel is attached to the bottom bracket and a weight is attached to the weight toothed wheel of the frame by means of a rider and a joint. Two swing frames can be attached to the frame and beams are attached to

the free ends of the swing frames in a rotating manner and the beams are connected with the cabins in a rotating manner.

According to this invention it is advantageous to make the float of this vessel of a hollow body provided with equipment to fill the hollow with water and also to empty the hollow. It is possible to attach a large- diameter wheel to the outer wall of the float and this wheel deviates from the outline of the float at least in one direction. It is advantageous to interconnect all driving mechanisms of the vessel with the cabin by the remote control through well-known elements and at the same time the use of a multiple protection is an inevitable requirement in this case, from the safety point of view it is indirect control checked by a set of computers.

The advantage of this design according to the invention is the great variability of its different constructional designs which enables to manufacture vessels for leisure-time activities but also vessels for various special purposes such as for instance observing undersea currents and water animals. The possibility of locating the cabin into the position under water surface in case of a thunder-storm is another advantage. This considerably eliminates the influence of the thunder- storm on the crew.

Fig. 8 shows the side- view of one more variant of the design of the vessel according to this invention. Fig. 9 shows the side-view of another possible constructional design of the frame of the vessel according to this invention.

Detailed description of the preffered enbidiments The vessel according to Fig. 1 to 3 consists of a frame 10 provided with a pair of beds 14 and two linear guideways 15. The shaft 11 and a pair of front wings 16 are attached to its front part perpendicularly to the longitudinal axis, and a pair of rear wings 17 and a boat engine 60 are attached to the rear part. The weight 50 is attached to both of the linear guideways 15 in a sliding manner and the weight 50 is located on the skids 54 and provided with a motor drive for its own straight motion. Each bed 14 is provided with two skids 43 attached to the float 40 in a sliding manner. The arm 41 of the float 40 provided with the float 40 is attached to the skids 43 of the float 40 by means of the bearing 42 in a rotating manner. The float 40 is a hollow body provided with equipment to fill the hollow with water and also to empty the hollow.

A large-diameter wheel (the wheel or more wheels are not shown in the fig. so that the fig. can provide an easy survey) is attached to its outer wall and the wheel deviates from the outline of the float 40 at least in one direction. The above-mentioned wheels are installed so that the vessel can move both on a dry land and the bed of a river, reservoir or a sea. All the skids 43 are provided with two driving mechanisms independent of each other. One provides a straight motion of the skids 43 of the float 40 along the bed 14, the other one turns the arm 41 of the float 40 on the plane perpendicular to the above-mentioned travel. The swing frame 20 is attached to the shaft 11 in a rotating manner by means of the hub 21 and secured by axial stops 12 and three arms 22 of the space lunette are attached to its opposite end. The swing frame 20 is

provided with an independent drive unit which turns it in relation to the frame 10. Each of the arms 22 of the space lunette is provided with two self-turning wheels 33 providing the antifriction attachment of the water- tight cabin 30 of a spherical shape. One of the arms 22 of the space lunette is manufactured as a hinged one from the point of view of security, however, properly secured against spontaneous movement.

The cabin 30 is provided with an adequate weight base 31 inside, located sufficiently under the centre so that it can safely adopt its horizontal position no matter what the tilting of the vessel is like. The drive of the rotation of the cabin 30 is attached in a rotating manner to one of the arms 22 of the space lunette. Its pendulum suspension provides the permanent vertical position of the axis of the driving gear which is in contact with the surface of the cabin 30 or with the indented belt attached to it respectively. The swing frame 20 is connected with cabin 30 with the cable 23 by means of a winch. From the point of view of security the cable 23 is detachable. There is remote control of all driving mechanisms of the vessel from the cabin 30 with well-known means, and at the same time the use of multiple safeguarding is an inevitable requirement in this case. From the point of view of safety the control is to be indirect, checked by a set of computers.

As was mentioned before, the purpose of the above-mentioned design is to enable the crew to enjoy an exciting "ride". The following text shall prove that the invention of the design according to Fig. 1 to 3 is very well equipped for this purpose. However, if all of its technical possibilities are to be employed, the vessel needs water deep enough, at least 80 m. This requirement depends on the size of the vessel. To get a clearer picture we shall use Fig. 1 with the vessel in its upright position and the cabin 30 in its topmost position (if the seesaw motion is to be a powerful experience) of 30 to 68 m above the surface. The surface is represented by the light line marked with the triangle. If the crew considers the seesaw motion too light, for instance owing to calm, it can rock the vessel by controlled movement of the floats 40, both sliding

and rotating, or it can use the driving mechanism to turn the swing frame 20. The deflection of the tilting of the vessel by the floats 40 can be implemented in two ways. It can be done either by turning the arms 41 of the float, for instance by the transition into the position when from a bird's eye view they form the shape "U" together with the frame 10 and then owing to the following turn by 1800 they form a reverse shape "U", or by implementing the travels of the skids 43 of the float 40 along one bed 14 upwards and downwards along the other bed. It stands to reason that all the three described movements can be executed simultaneously, or they can be mutually combined in various ways. The same means are used for the so-called "prostrating" of the vessel on the surface, during which the cabin 30 pitches on the surface. When implementing this, it is also necessary to make use of the movement of the weight 50 in the direction of the front part of the frame 10. The longer the travel covered by the weights 50, the more the cabin 30 as a float will dip. The same effect will be achieved by the travel of the floats 40 in the opposite direction. After reaching extreme positions the vessel will take the position shown in Fig. 2 in which the cabin 30 is in the lowest position under the surface. If the crew feels like submerging completely, it will start to fill the floats 40 with water. During this, particular functional elements, in cooperation with computers, will be located so that the vessel is ready to touch down the bed with its four wheels attached to floats 40. At the same time they will be arranged to be as far away from one another as it is possible to increase stability. It stands to reason that the movement of the vessel under the surface will be provided by a boat engine 60, even during the drive on the bed. It will show above the surface after letting water out of the floats 40. In case of a failure of particular equipment when it is not possible to show above the surface with the vessel the crew has the possibility of releasing the cabin 30 by removing one of the arms 22 of the space lunette. To limit its considerable speed, when rising to the surface, resulting from the lifting force there is the cable 23 with the winch. The above-mentioned elements can be used in case of the need to fasten the cabin 30 to the

vessel again or when there is the requirement to submerge as a means of protection from the sun, thunder-storm, in case of a danger of a collision with another vessel etc. It is evident that the remaining steel body on the bed will have the function of an anchor. As was mentioned earlier, the vessel can be used for the classical passage on the surface.

To have a better understanding, follow Fig. 1 again, this time, however, ignore the drawn surface and create the idea that we observe the vessel from above. If it is necessary to minimalize the draught, then it is necessary to optimize especially the positions of the swing frame 20 and also the floats 40 and the weight 50. This means that the cabin 30 is submerged in an optimum depth which results in the lifting of the vessel because the cabin 30 serves as a float in this case. At the same time it is necessary to move the floats 40 to the rear part of the frame 10, see the dot-and-dashed position of the floats 40 on the right bed 14 Fig. 1, and to move the weight 50 so that the draught is the same everywhere. It stands to reason that it is better to leave this operation to computers.

During passages through straits, for example through lock canals, it is useful to move floats from the outer side of the frame 10 to the inner side (in Fig. 1 marked dot-and-dashed); this is achieved by turning the arms 41 of floats 40 by the angle of about 1800. During a passage on the surface the crew has the choice of several possibilities. It can either decide on a passage with the cabin 30 more or less dipped or completely submerged in a chosen depth for instance for the purpose of admiring the beauties of nature, or on the contrary it will reap the advantage of spending the passage in a changeable height above the surface. The side-view of the vessel shows the last possibility, see Fig.

3. What is clear from it are the necessary locations of the pairs of floats 40 in front and rear extreme positions of the frame 10 for the purpose of increasing the stability of the vessel. By turning the arms 41 of floats 40, in Fig. 3 marked dot-and-dashed, it is possible to increase or decrease the draught of the frame 10. The above-mentioned possibilities can be used to optimize the depth of the draught of the frame 10 for the need of easier starting of the regime of the passage with the smallest water

resistance when the vessel slides on front wings 16 and rear wings 17.

For the purpose of further diversification of the passage it is possible to release the cabin 30 and let it swing on the cable 23 of a select length even during other functional regimes of the vessel in comparison with what was stated. One of the tempting alternatives can be constituted by a fast drive on the surface in a rocking cabin 30 suspended at a changeable height on the cable 23. Another, and far from being the last, possibility is a sort of dragging the cabin 30 on the surface several meters after the vessel in the environment of rapids resulting from the activity of the boat motor 60.

Fig. 4 shows the alternative of the constructional design of the cabin 30 according to Fig. 1 to 3. In this case it is not the antifriction attachment of the cabin 30 that is used but a firm attachment which is, however, detachable from the swing frame 20. The base 31 is used to stabilize the position of the crew and its self-rotating wheels 33 of the carriage on the inner spherical surface of the cabin 30.

Fig. 5 shows the constructional extension of the design according to Fig. 1 to 3, and 4 respectively. The extension is based on adding a few constructional elements to places between the swing frame 20 and the arms 22 of the space lunette. It is the tilting frame 24 connected with the end of a swing frame 20 by means of an articulated joint and interconnected with an independent engine. The free end of the tilting frame 24 is provided with a gearing engine to the rotating part of which the rotor is attached. One of the free ends of the rotor is provided with three arms 22 of the space lunette, the other one with the counterweight 27. The antifriction attachment of the cabin 30 in the space lunette corresponds to the above-mentioned description.

The design according to Fig. 5 extends the functional possibilities of the vessel. It enables the movement of the cabin 30 on a circular line with the diameter of several meters. Thanks to the hinged arm 24 with

the driving mechanism it will be possible to change the tilting-of the above-mentioned circular line with respect to the surface. If along with this motion the rotation of the cabin 30 is started in the space lunette, then at the mutual counterrotations and equal speeds of rotation the rotation is stopped in relation to the surface. It will help the crew in finding its bearings without missing the experience of the often very complicated final movement which is enabled by the vessel. One of the rather interesting experiences can be initiated by the functional regime during which the cabin 30, when the rotor moves, is suspended on the cable 23. Then it is possible to move on circular iines with the diameter of several dozens of meters, close to the surface.

The constructional design according to Fig. 6 consists of the float 40 of a cigar-like shape inside of which is built in the electric boat motor 60 with an electric accumulator. The double frame 10 is attached to the float 40 in a rotating manner. The beam 25 is attached to the upper free arm of the frame 10 in a rotating manner. The crank 71 is attached in the bearing 26 of the beam 25 in a rotating manner and by means of the bearing 34 of the cabin 30, the cabin 30 is attached to the crank 71 in a rotating manner. The crank 71 is provided with the driving mechanism 72 of the rotation of the cabin 30, whose driving wheel is in contact with the cabin 30, or with the toothed wheel respectively with which it is provided.

To stabilize the turn by an angle of the beam 25 in relation to the float 40 a precision gear is used. This consists of a fixed chain wheel 81 attached to the float 40 co-axially to the axis of rotation of the frame 10, the turning chain wheel 82 connected with the crank 71 and the chain 80 of the position gear. The connection of the turning chain wheel 82 with the crank 71 is implemented by means of a not drawn self-locking gear controlled from the cabin 30. The weight 50 is attached to the bottom arm of the frame 10 by means of the skids 54, weight 50 and the joint 52 this weight 50 is provided with wheels 58 on its bottom part. The connection between the frame 10 and the skids 54 is sliding. Its travel in the direction of, or from the rotating connection of the frame 10

respectively with the float 40 is limited as far as the travel is concerned by the adjustable stop 55 and it is activated from the cabin 30.

The described design according to Fig. 6 enables the crew to expose itself to a multiple-combined motion which can be mostly controlled and checked by the crew. This will usually consist of the classical forward movement or the backward movement respectively resulting from the activity of the boat engine 60 and the pendulum motion both in the direction of the longitudinal axis of the float 40 and in the direction of the axis of the rotating connection of the frame 10 and the float 40 brought about by waves and wind. The excitement of the drive can be enriched by starting the rotation of the cabin 30 by initiating the driving mechanism 72 of the rotation of the cabin 30. It can be further enriched by the simultaneous tilting of the axis of rotation of the cabin 30 (see marked dot-and-dashed in Fig. 6) which the crew can change regularly. It is necessary to note that the adjusted inclination of the axis of rotation of the cabin 30 is independent of the tilting of the frame 10 in relation to the surface because it is stabilized by the position gear.

Stabilization of the position of the cabin 30 is provided by the rotating connection of the crank 71 and the beam 25 so that the resulting centre of gravity is located enough under the axis of the above-mentioned connection. It is therefore the stabilization by means of gravity. Basic influence on the function of the vessel will depend on the momentary distance of the weight 50 or the skids 54 of the weight 50 respectively from the rotating connection of the frame 10 with the float 40. This distance is controlled form the cabin 30 within the range given by the adjustable stop 55. This must be properly set in advance depending on the weight of the crew so that one of the extreme positions secures a safe overbalance of the arm of the frame 10 on the side of the beam 25 and thus enables the cabin 30 to touch down the surface, and the other extreme position secures the overbalance of the arm on the side of the weight 50 having lower sensitivity to rocking under the usual weather conditions. The degree of sensitivity or the passage on the surface are

therefore chosen by the crew itself. The wheels 58 lowers the friction when the weight 50 gets onto the inclined plane under the water near a bank. This secures the lifting of the weight 50 and thus the required touch down of the cabin 30 on the bank.

Fig. 7 shows a constructional alternative with two floats 40 firmly connected to the frame 10. The sleeve 13 is part of the centre of the frame 10 and the turntable 56 is attached in a sliding manner in it. A pair of the upper brackets 91 and bottom brackets 92 are part of the turntable 56. The frame chain wheel 85 is attached in a rotating manner in the upper brackets 91. The weight toothed wheel 86 is attached in the bottom brackets. Both of the above-mentioned wheels 85 86 have the same number of teeth and form along with the chain of the pendulum gear 84 a precise, so-called pendulum gear. The swing frame 20 is attached to the frame chain wheel 85 , the skids 54 to the weight wheel 86. The swing frame 20 is connected to the beam 25 in a rotating manner and in the same way as was described in the previous design according to Fig. 6. By comparison of the mentioned pictures we can find out a constructional correspondence with both the attachment of the cabin 30 and its driving mechanism and constructional design of the stabilization of the position of the cabin 30 by means of the stabilizing gear consisting of toothed wheels 81, 82 and the chain 80. It stands to reason that the fixed toothed wheel 81 is attached to one of the upper brackets 91 co-axially to the frame toothed wheel 85. Analogously with the preceding design the sliding location of the skids 54 is implemented in the weight toothed wheel 86 for the purpose of adjusting its projection and its articulated joint with the weight 55. Even here the travel of projection is limited by the adjustable stop 55 and the movement of the kids 54 is controllable from the cabin 30. In comparison with the design according to Fig. 6, the described vessel has considerably higher stability and therefore it can be extended with two driving mechanisms.

Both are controllable from the cabin 30. One consists of an electric motor which is attached to the frame 10. The driving toothed wheel 88 is

attached on its shaft which is, by means of the indented belt 87 connected to the teeth of the turntable 56. The other driving mechanism is used to turn the swing frame 20 in the upward - downward direction, it is not shown in Fig. 7. For the purpose of blocking this movement the above-mentioned driving mechanism is provided with a brake which is not shown either.

Functional abilities of the vessel according to Fig. 7 resemble those of the previous one according to Fig. 6. They differ in the fact that the position of the cabin 30 can be exactly controlled, for instance both its height and the position of its touch down of the surface. Functional possibilities of the vessel are therefore extended by the possibility to control the movement of the cabin 30 on an imaginary hemisphere.

During the regime when the crew selects the blocking of the swing frame 20 and at the same time the starting of the rotation of the turntable 56 the cabin 30 will move on a horizontal circular line. If it starts to rotate the cabin 30 in the opposite direction but with the same angular speed, the crew will maintain a constant direction of the view. It is clear from what is written that the diameter of the circular line being run will differ with the change of the height of the cabin 30.

Fig. 8 shows the vessel with two cabins 30 whose swing frames 20 move parallel to one another. Fig. 8 shows the constructional alternative with two floats 40 firmly connected with the frame 10. The frame chain wheel 85 is attached to the bent ends of the frame 10 in a rotating manner and the weight toothed wheel 86 to the centre of the frame 10. Both of the above-mentioned wheels 85 86 have the same number of teeth and they form together with the chain of the pendulum gear 84 a precise so-called pendulum gear. The swing frame 20 is attached to the frame chain wheel 85 , the skids 54 to the weight wheel 86. The swing frame 20 is connected with the beam 25 in a rotating manner and in the same way as was described in the previous design according to Fig. 6 and Fig. 7. By comparison of the mentioned pictures

we can find out a constructional correspondence with both the attachment of the cabin 30 and its driving mechanism and constructional design of the stabilization of the position of the cabin 30 by means of the stabilizing gear consisting of toothed wheels 81, 82 and the chain 80.

Analogously with the preceding design the sliding location of the skids 54 is implemented in the weight toothed wheel 86 for the purpose of adjusting its projection and its articulated joint with the weight 55. Even here the travel of projection is limited by the adjustable stop 55 and the movement of the kids 54 is controllable from the cabin 30. In comparison with the design according to Fig. 6 the described vessel has considerably higher stability and therefore it can be extended with two driving mechanisms. Both are controllable from one of the cabins 30.

One consists of an electric motor which is attached to the frame 10.

Functional abilities of the vessel according to Fig. 8 resemble those of the previous one according to Fig. 6 and Fig. 7. They differ in the fact that the position of the cabin 30 can be exactly controlled, for instance both its height and the position of its touch down of the surface.

Fig. 9 shows the possible design of the frame 10 which has the shape of a circle on the ground plan. The frame 10 is therefore formed by a circle on which are located the skids 43 of several floats 40 by means of bearings so that the floats 40 can move on a circular line of the frame 10. The skids 54 of the weight 50 are attached to the frame 10 and they can also move on the circular line of the frame 10. Next the swing frame 20 is attached to the frame 10 and the cabin 30 provided with the base 31 is attached to the swing frame 20. This design can also be complemented with further elements mentioned in the previous examples.
