Definitions

  • the invention relates to a floating body with a hollow sphere enclosing a person receiving space, which is accessible through at least one opening and can be connected to the atmosphere via air openings.
  • Floating bodies of this type have previously been used as diving balls which are accessible from below and whose air openings were connected to the atmosphere via hoses and pumps.
  • the object of the invention is to create a floating body which is capable of swimming on the water surface and in which it is ensured, even in unfavorable weather conditions, that the person (s) located inside are not damaged, so that this float can optionally be used as a lifeboat.
  • the floating body consists of an outer ball and an inner ball which is freely rotatable in this in every direction, the outer ball consisting of at least two parts which can be tightly connected to one another via a connecting device exists and between the outer ball and the inner ball a number of roller bearings are arranged, the height of which corresponds to half the difference between the inner diameter of the outer ball and the outer diameter of the inner ball, and that finally at least the inner ball is provided with a weight arrangement for shifting its center of gravity below the center of the Schwirnmlik .
  • At least the outer ball is double-walled and can preferably be sealed by means of a cover.
  • the bottom opening is generally not closed in order to give the diver the opportunity to carry out work.
  • the penetration of water is avoided in that an overpressure atmosphere is constantly maintained within the person receiving space, which naturally places a heavy burden on the human organism.
  • roller bearings are preferably formed by ball bearings, although the use of roller bearings, in particular with pivotably mounted roller cages, is also conceivable and would also have the advantage of a larger support surface compared to ball bearings.
  • the inner ball is more flexible on ball bearings.
  • the weight arrangement on the outer ball can also be achieved in that it is provided in the floor area with an encapsulated motor housing, in particular for an electric motor, and a propeller or a rudder in order to ensure at least a minimal navigation option when used as a lifeboat. This then entails the necessity of housing batteries and the tight passage of at least the electrical wires (if the motor housing is arranged outside) through the wall of the outer ball.
  • the known diving balls consisted of pressure-resistant metal due to the high pressure acting on them, for the purposes of the invention it is more favorable to manufacture at least the parts of the outer ball that can be connected to one another, preferably also the inner ball, essentially from plastic, and expediently at least the outer ball to be double-walled.
  • the floating body according to the invention is relatively light and yet stable, with stiffening ribs, insulating material, but also stabilizing weights in the lower region or a gas, e.g. under pressure, can be accommodated in the upper area.
  • the outer ball is preferably made of a material with a coefficient of thermal conductivity below 0.35, preferably around 0.035. These values can be achieved particularly easily if the outer ball is made of plastic in the manner described above.
  • the space for people is practically limited by the cavity of the inner sphere.
  • the relationship between the displacement space of the outer ball and the usable interior space can be unfavorable, which can lead to difficulties when storing the boat. It has now been found that a ratio of the inside diameter of the outside ball to the outside diameter of the inner sphere under 9: 7 creates particularly favorable conditions, and an optimum was found at a ratio of 37: 35, the actual dimensions being 1480: 1400 mm.
  • the outer ball possibly also the inner ball, is made up of two ball halves divided along the ball equator.
  • the entrance hatch is provided on the underside of diving bells.
  • the outer ball is optionally freely rotatable, the place of the arrangement is undefined its entry opening, although in the case of stabilization of the outer ball, the attachment of these O e opening in aligned position with that of the inner sphere is indicated.
  • the entrance hatch or the cover of at least the inner ball or the outer ball is arranged approximately at the interface of the connecting line between the center of gravity and the center of the floating body with the ball wall. It can then be arranged in such a way that its center lies exactly in the extension of the line drawn through the center of gravity and the center of the sphere, but it can also be offset somewhat from it, with a more lateral attachment May facilitate boarding.
  • the weight arrangement of the inner ball preferably comprises at least one seat, preferably below which there is at least one space for storing and / or fastening items of necessity, e.g. of the drive batteries mentioned, for the occupant of the float for the purpose of shifting the center of gravity downwards.
  • these items can then either be parked on a footprint below the seat and / or simply attached by means of lateral holders arranged on the spherical body.
  • the floating body according to the invention should be able to serve as a ship on its own. It is therefore expedient if portholes, which may correspond to openings in the inner ball, and / or ventilation openings are provided on the outer ball, preferably the upper half of the ball, the latter of which Valves can be closed, which preferably have a closure body which can be actuated by the dead weight and / or by the external pressure.
  • valves it would also be possible for these valves to be actuated by hand, for example by opening the valve located above the entry hatch and locking it in the open position, this locking preferably being released automatically when the valve moves out relative to the edge of the entry hatch and the valve returns to the closed position under the action of a return spring.
  • the occupants should be relieved of this actuation work, the safety of the actuation being increased by means of the automatic closure body if two closure bodies which can be moved independently of one another, e.g. made of different materials, such as metal and plastic, are provided so that sand grains reaching the area of a closure body, for example, cannot impair the function of the valve.
  • Stainless steel is favorably used as the metal.
  • the term “outer sphere” is to be understood in the sense of a spherical interior, whereas the outside can also deviate from the spherical shape, for example for stabilization or signaling purposes.
  • the ball can have lateral floating bodies, for example in the manner of an outrigger boat or in the form of a floating torus arranged in the region of the ball equator or below.
  • the air openings can be connected to floating buoys via hoses in order to allow a load on the ball which submerges it below the water surface.
  • a drive is attached to the It can be advantageous to give the underside of the outer sphere a streamlined shape on the outside.
  • SOS signature field
  • a floating body 1 has an outer ball 2a, 2b composed of two ball halves 2a and 2b, in which an inner ball 3a and 3b, likewise made up of two ball halves 3a and 3b, is rotatably supported in all directions by balls 5 guided in ball cages 4.
  • balls 5 guided in ball cages 4.
  • only one ball bearing 4, 5 is shown, but it is understood that at least six will be required to support the inner ball, and in in practice there are many more.
  • the number of these roller bearings depends on the dimensions of the balls 2a, 2b or 3a, 3b and can be fifty in a practical case.
  • the ball cages are fastened to the outer wall of the inner ball, but - as already explained - it can be more favorable for some applications to fasten the ball cages 4 to the inner wall of the outer ball 2a, 2b. Furthermore, it may be advantageous to distribute the ball bearings unevenly over the ball surface, since - as will be explained later - the position of the inner ball is stabilized and therefore always rests on the inner surface of the outer ball 2a, 2b with the underside shown in FIG. 1 .
  • the balls 2a, 2b and 3a, 3b are preferably made of plastic, e.g. glass fiber reinforced polyester plastic. At least the outer ball 2a, 2b is preferably double-walled in the manner shown, the cavities 6 resulting therebetween being provided with an insulating compound 7, for example foamed. A good insulation value can be achieved in this way.
  • the cavity 6 is however - not least for stiffening - divided by transverse ribs 34 in the manner shown.
  • the lower cavities 6 can be filled with solid insulating material, whereas the upper cavities 6 contain a gas, for example under pressure. This will shift the focus tes reached downwards relative to the center of the sphere. If the float is to be equipped with a drive, the lower cavities can also contain parts of the drive unit or batteries.
  • Each of the two outer spherical halves has an annular recess 8a or 8b, which together form a groove 8a, 8.
  • each ball half 2a or 2b has a flange 9a or 9b, with the aid of which the ball halves 2a, 2b can be connected to one another by means of screws 10.
  • the arrangement of the flanges 9a, 9b has two reasons. On the one hand, they are protected within the groove 8a, 8b, so that the floating body 1 running up against cliffs, quay walls or the like does not result in any load on the fastening device 9a, 9b and 10.
  • a good seal can be achieved with the aid of a U-shaped rubber profile ring 11, the legs of which resiliently rest against the side walls of the groove 8a, 8b.
  • These side walls can optionally be provided with a sawtooth profile in the manner of fittings.
  • the rubber profile ring 11 can also be designed as a wide rubber bead, the Leg resiliently inward on the flanges 9a, 9b and are anchored there, for example, in ring grooves with engaging beads or rubber teeth (or vice versa: on ring-shaped projections of the flanges with ring grooves of the rubber profile ring 11).
  • the rubber ring 11 can additionally be glued or welded to the walls of the groove 8a, 8b.
  • 0-rings can be provided in ring grooves on the mutually facing end faces of the ball halves 2a, 2b. These end faces are preferably graduated and interlocked in such a way that a labyrinth seal also results.
  • Cylindrical recesses 12 are expediently distributed over the surface of the outer ball, which on the one hand enclose air openings 33 with air valves 13, and on the other hand also enclose portholes 14.
  • the reason for the arrangement of these parts in recesses 12 is the same as described above in connection with the flanges 9a, 9b: the valves 13 and the portholes 14 are to be secured against impacts.
  • the portholes 14 of the outer ball 2a, 2b correspond to viewing openings 27 of the inner ball 3a, 3b. These viewing openings are preferably dimensioned somewhat larger in order not only to receive light when the windows 14 and 27 are aligned exactly.
  • the storage does not interfere with these recesses, since they are provided on the inner ball only at the top, where the ball bearings 4, 5 do not have to absorb any forces.
  • a ball bearing 4, 5 sitting on the outside of the inner ball 3a, 3b does not find any support, but the other ball bearings then provide appropriate support.
  • the upper ball half 2a of the outer ball 2a, 2b has a sealing hatch cover 16 which is provided with a sealing ring 15 and can be pivoted about a watertight hinge 17 and which can be closed by means of three rotary locks 18 (only one is shown).
  • the open position of the cover 16 is indicated by dashed lines.
  • the construction of the cover is of any type in itself, as is known in the relevant art, e.g. of tower closures in submarines, is known, so that a detailed description can be omitted.
  • the entry hatch of the outer ball 2a, 2b which can be closed by the cover 16 corresponds to an entry opening 21 of the inner ball 3a, 3b.
  • the outer ball 2a, 2b has an undefined position and therefore its entry hatch cover can also move downwards (based on FIG. 1) due to a relative movement to the inner ball, the entry opening 21 of the inner ball 3a, 3b is always located on the Top because this ball is stabilized in its position.
  • This weight arrangement preferably comprises at least one annular seat 22, which is equipped with a floor grating 23. Under the latter is a bilge 24, which is intended to absorb condensation in a known manner.
  • a free space 25 located beneath the seat offers space for accommodating various items, such as food supplies, drinking water tanks, biological toilets, batteries for the drive mentioned or for any emergency lighting or a beacon mounted on the outside, etc.
  • the inner ball 3a, 3b can also be provided with air openings 26, the number of which is generally higher. For example, 100 ventilation openings 26 and thirty-six light openings 27 (only one each is shown) can be provided.
  • hand holes (not shown) on the side of the upper inner ball half 3a, if it should become necessary to bring the two entry openings from the outer and inner ball into alignment for the exit. Through these relatively wide hand holes then, for example from recesses in the inner wall of the outer ball 2a, 2b, radially protruding handles are gripped and by means of which the outer ball 2a, 2b are rotated into the corresponding position.
  • the outer ball 2a, 2b has an outer diameter mm by 1736 mm has an inner diameter of 1480.
  • the A ssenwand and the double-walled construction is l5 mm thick, the inner wall has a thickness of 12 mm.
  • the inner ball 3a, 3b is formed in the manner shown only with a simple wall of 10 mm thickness, especially since it has practically no insulating function. However, for reasons of stabilization, it may also be advantageous for the inner ball 3a, 3b to have a double-walled design, and in the case of larger dimensions of such a floating body, this double-walled design can also serve to accommodate a stiffening skeleton.
  • the connecting flanges 19a, 19b protrude inwards and are expediently covered there by rubber beads in a manner not shown in order to avoid injuries to the occupants in rough seas.
  • the flanges 19a, 19b can also be directed outwards, provided that their radial dimension is less than that of the ball bearings 4, 5. This would easily avoid any risk of injury.
  • Both flanges are screwed together again with forty four screws measuring 3/8 "x 45 mm, whereby - as mentioned - the facing end faces interlocked to form a labyrinth seal (not shown) or sealed with O-rings which can be sealed in along the This construction is also suitable for the two halves 2a and 2b of the outer ball 2a, 2b.
  • the floor grate is made of 50 mm thick pine wood, as is the seat 22, which is only 210 mm high. As a rule, this mass is sufficient, but can be varied if necessary.
  • the air openings 33 can have a diameter of about 10 mm, whereas the portholes 14 - and in the embodiment shown also the inner light openings 27 - have about ten times the diameter, ie 100 mm.
  • the valve 13 on the inside of A u ssenkugel 2a, 2b comprises a valve body 28 with a siphon air duct 32, 29, 33.
  • the channel section 29 is conical and contains at least two balls 30, 31 serving as closure bodies, of which the larger ball 30 is made of metal, in particular stainless steel, and the smaller ball 31 is made of plastic.
  • the two balls are either at one valve seat under the effect of gravity Forming conical wall of the channel section 29 pressed or they reach the position shown in dashed lines, in which they release the air channel 32, 29, 33.
  • the two balls 30, 31 In the position shown with solid lines, not only does gravity act on the balls 30, 31, but these are also loaded by the water pressure from the outside via the channel section 32. Even if contamination should prevent one of the balls 30 or 31 from sealingly seated, at least the other ball will certainly block the channel system, so that water infiltration is prevented in any case.
