Definitions

  • the invention relates to a locomotive device, in particular an engine-driven boat having a catamaran-like body of at least two parallel tube bodies disposed in a mutually spaced relationship and a bottom disposed between them at a distance from the underside of the tube bodies (claims 1 , 2 or 3 ).
  • Such a keel-less “vehicle” (boat, boat body, gliding device or locomotive device or boat device) is to be designed in such a way that it is equally suitable for use, preferably for rescue missions, on water and ice surfaces.
  • the boat device according to the invention is especially suited for rescue missions on water bodies such as lakes, whose body of water usually freezes up at least partly.
  • rescue missions with only floating boats are no longer possible in these cases.
  • a rescue mission across a large ice surface is troublesome and time-consuming. This also applies to fire brigade missions from the mainland on an island, the water being frozen up.
  • a rescue mission is not hindered with the locomotive device according to the invention, it being possible to rapidly and safely carry out the mission carrying along any necessary rescue equipment and a rescue team, since the locomotive device can be moved with equal safety and speed and without the difficulties of transition both on ice and on water.
  • the bow area of the boat body may be a further tube body uniting the two tube bodies or a rod (claim 4 or 5 ).
  • a slide-on slope is formed in the bow area (claim 3 ) which makes the gliding onto ice safe and impact-free during transition from water to ice. The gliding on only a frozen surface, driven by the propeller, thus takes place without trouble, as well.
  • the area defined by the tube bodies is preferably occupied by a relatively firm bottom (claim 2 ), which is disposed at a distance from the gliding surface and lowered with respect to the center of the tube bodies. Towards below this bottom is completely covered by a second bottom part which may consist of the same or a similar material as the outer tube cases (claim 6 ). Rubberized Kevlar tissue is very well suited. During movement on an ice surface an air cushion is formed between the raised (covered) firm bottom and the gliding surface, which provides for a buoyancy and, thus, for instance for a higher speed (with the same driving power) or causes a load on the ice with lower contact forces during the drive.
  • a frame support for the propeller propulsion may be affixed to the firm bottom, preferably in an easily detachable fashion.
  • the invention is based on the object of further developing an engine-driven device of the mentioned type in such a way that it can be easily, reliably and effectively used in the situations mentioned at the beginning.
  • difficult conditions may prevail during these missions such as the frequent alternation of water and ice surfaces, piled up ice or pack-ice, strong or gusty wind or pebbles and boulders with sharp edges and the like.
  • It must be possible to use the locomotive device under all weather conditions and the device must be capable of accurately and quickly heading for sites of an accident that are difficult to access.
  • U.S. Pat. No. 5,112,257 certainly shows a vehicle that is to be usable on water and on ice.
  • two tube bodies are inserted into a shell body and tied up with it by means of straps.
  • the shell be flexible, this would mean that the distance of the tubes is changed, wherewith the entire rod-shaped structure that is strapped to the tube bodies with the straps would be distorted. If this is to be avoided, the shell as a whole must be practically rigid, which renders the motion on rough ice extraordinarily more difficult and impairs steerability of the device to a great extent.
  • the load of the propulsion and appertaining means must be directly received by tube bodies which are flexible per se.
  • the propulsion force of the drive is predominantly only transmitted into the bow area to that point where the two tube bodies meet and, from there, it is transmitted to the ends of the tube bodies via an inflated tyre.
  • the vehicle is hardly steerable on difficult, irregular ice surfaces, in particular in view of the difficult weather conditions that prevail at the same time. Due to the attachment of the propulsion and control means directly on the tube bodies, the free space necessary for rescue missions and the appertaining means is missing on the device.
  • FR-A 2,323,573 and U.S. Pat. No. 6,148,757 show rigid, profiled boat bodies, in which floating bodies are inserted or formed.
  • WO-A 01/12501 starts from a different objective, namely to provide components that can be assembled to manifold shapes in order to obtain vehicles with a different length or width and different propulsions for different purposes.
  • Only a bottom is provided in all embodiments, which consists of hollow chamber plates which are firmly connected both at their edges adjoining each other and the tube bodies and are additionally stiffened by stiffening elements (there 88). The distance of the inflated tube bodies is determined by this bottom. Skids can be mounted on the undersides of the tube bodies through complex and partly inflatable substructures with a construction height that corresponds approximately to the diameter of the tube bodies themselves. Wear-resistant guide strips for increasing the lateral stability and steerability, which are directly mounted on the underside of the tube bodies, are not provided.
  • FIG. 1 shows a perspective view of the structure of a keel-less boat device
  • FIG. 2 shows a top view of the main body with the supporting frame being supported on the bottom;
  • FIG. 3 shows a cross-sectional view of the structure of the main body
  • FIG. 4 shows a longitudinal section with further details
  • FIG. 5 shows a modification of the design according to FIG. 4 ;
  • FIG. 6 shows a detail of a contact area of one of the tube bodies on an enlarged scale
  • FIG. 7 shows the lateral view of a detail
  • FIG. 8 shows a detail of the clamping of the firm bottom

  • FIG. 13 shows a modified example of embodiment in the same representation as FIG. 12 ;
  • FIG. 14 shows a top view of the arrangement of FIG. 13 (from below);
  • FIG. 15 shows a lateral view of a further detail in the stern area.
  • the main body of this motorized locomotive device substantially consists of a catamaran-like arrangement of two parallel tube bodies 1 and 2 preferably subdivided into chambers.
  • said tube bodies may connected to each other at the ends pointing in the direction of motion by a bow part 9 or a rod 5 that also consists of a tube section ( FIG. 5 ).
  • the front sections of the bodies 1 and 2 are inclined forwards and upwards at the angle ⁇ in order to thus form a slide-on slope and to facilitate transition from water to ice or ice floes.
  • the tube bodies are connected to each other by means of a flexible bottom layer 5 according to FIG. 3 , which is preferably made of the material of the tubes and is firmly connected to the bodies, preferably by means of gluing.
  • the connecting line 5 a is located between the underside 4 (plane 4 a between two undersides) and the plane 3 of the tube bodies 1 and 2 , which connects the tube centers, this being evident from the distances a and b.
  • the edges of a further bottom 6 adjoin along the connecting line, which may consist of wood, rigid plastic material or the like.
  • Said bottom 6 consists preferably of several plates of so-called marine plywood.
  • the bottoms 5 and 6 are dimensioned such that, with the tube bodies being inflated, the bottom 6 is clamped between the tube bodies and the fastening area 5 a of the bottom 5 at 6 a under tension in an inner shoulder that is limited on two sides, in order to determine distance c.
  • Said bottom 6 serves as a supporting and assembly bottom and is correspondingly dimensioned.
  • FIG. 8 is a modified clamping assembly of bottom 6 on the diverging tube section 2 a showing details of the clamping position 6 b at a vertical distance a 1 from the underside 4 .
  • FIG. 9 A modified embodiment of the areas is shown in FIG. 9 , where the bottom plates 6 adjoin the tube bodies 1 , 2 and are held there.
  • a U-shaped rod section 69 that is elongate vertically to the plane of projection grips over the plate edges adjoining the tube bodies.
  • a web 69 a projects from its closed side in the direction of the adjoining tube body 2 .
  • a further rod section 67 is located above the web which, on the one hand, nestles around the closed end of section 69 and, on the other, against the outer skin of the tube body and supports web 69 a from above. From below, the web is supported by a hard rubber section 68 which like rod section 67 is firmly connected to the tube body by means of gluing (along the adhesive strips 67 a and 68 a ).
  • the second, flexible bottom 5 is glued to section 68 and the tube body at 5 b . If the tube body is firmly inflated, rod section 69 is firmly clamped between rod section 67 and hard rubber section 68 and, thus, bottom 6 is safely anchored between the two tube bodies.
  • a protective strip is shown at 8 , which will be described in greater detail in connection with FIGS. 3 and 6 .
  • the bottom 6 and/or the bottom plates arranged in a row are held in the U-shaped section with screws (not shown).
  • the tubes and the additional bottom 5 are designed in a reinforced fashion, e.g. with a rubberized Kevlar tissue.
  • Resilient strips 7 or 8 are affixed to the contact area of the tubes and the underside of the bottom 5 for protection against friction, said strips 7 consisting of a wear-resistant material.
  • Several of said strips 7 are in each case disposed at a mutual distance in the contact area with an arcuate cross-section according to FIG. 6 .
  • the lateral edges of strips 7 and 8 are preferably of a sharp-edged design so that they contribute to improving the lateral guiding and steerability of the vehicle on ice.
  • the sharp edges 7 b are preferably provided on an additional supporting cover 7 a of strips 7 , 8 so that they act as skids.
  • a front area 17 according to FIG. 4 and FIG. 5 of the bottom construction is designed as a part swivelling about the transverse axis 18 .
  • the bottom portion 5 is not fastened to the bow portion 9 and/or the rod-shaped connection 9 a with its front edge and, in lateral areas, is connected to bodies 1 and 2 forming one fold 5 a each in this area, which make a downward swivelling of element 17 in the direction of arrow 20 possible.
  • the actuation of the flap-like bottom 17 takes place through a biased actuating means 19 . This facilitates the rescue of persons who can be carried more easily into the vehicle over the slope. If, instead of the bow portion, a connecting rod 9 a is provided, rescue is still further facilitated since the rod may also serve as a grip.
  • a frame support 10 is fastened to the bottom 6 in an easily detachable fashion, e.g. by means of four bolts, on which, in the example of embodiment, the drive (via supporting rods 20 ) and all equipment elements of the vehicle can be mounted.
  • the support 10 consists of a rear portion 11 and a front portion 12 .
  • a motorcycle-like seat box 30 with steering means 32 is mounted on the front portion 12 of the frame element 10 .
  • the propeller propulsion is shown in FIG. 1 at 25 to 27 .
  • the ends of the two tube bodies are firmly connected to each other by an approximately upright stern plate H, which, preferably, is also made of marine plywood. Said stern plate may be used for supporting various additional means.
  • a blade-shaped rudder 15 which is lowerable between a standby position and an effective position and connected to the handlebar in parallel to the lateral rudder 27 may be provided on said stern plate in order to support steering in water.
  • Said blade 15 is connected ti a liftable and lowerable swivelling support 51 which can slide up and down in a sleeve 51 a and is rotatably connected to said sleeve via a toothing, whereas the sleeve itself is rotatably mounted and connected to the sheathed cables 53 of control 32 through lateral arms 52 .
  • Everything is mounted on the frame support 10 .
  • braking elements for slowing down the vehicle during a drive on ice may be mounted on the stern plate H.
  • said braking elements may be designed with one or two arms 13 a , 13 and they may be pivotable about a transverse axis 55 , 55 a and comprise brake spikes 54 , 54 a on their free ends.
  • Arm 13 is under the bias of a strong spring 58 which is locked at 59 or arm 13 a is pneumatically 58 a controllable.
  • the locking bar may be loosened by means of sheathed cable 60 .
  • the supporting box 56 is the mount for mounting the brake elements.
  • the ice surface is outlined with 57 .
  • elements may also be mounted on the stern plate H, which serve for a transport or locomotive possibility on land, if the glider is not being used, such as an arrangement with a supporting wheel 62 on a crank means 64 with vertical drive 63 which is capable of being extended and retracted in order to lower or lift the supporting wheels depending on the type of use.
  • Two auxiliary lines 65 , 66 are drawn which make a symmetric arrangement possible, however, a one-sided arrangement is also realistic. If a symmetric arrangement is chosen, the two mounting positions are symmetrically located along the auxiliary lines 65 , 66 on both sides of the central plane (the vertical central plane) of the boat body.
  • the described supporting wheel means may be used in connection with a lever that is guided on a wheel, which is used on land on the opposite (bow) side, said lever having an upwards projecting nose portion (not shown) for engagement with a recess, e.g. a groove, which is provided on the bow and points downwards.
  • the nose portion is substantially shorter than the lever and they are at an angle to each other which is greater than 45°, preferably between 60° and 150°, in order to insert the nose portion into the recess by means of a swivelling of the longer main lever, so that the boat can be lifted and, drawn by the longer lever arm, be driven on the supporting wheel that is supported on the rear side.
  • each skid 38 may be provided on the tube bodies.
  • the length of said skids must be chosen small, based on the length of the bodies 1 , 2 , preferably less than 1 ⁇ 4 of the length, so that the flexibility of the bodies 1 and 2 is not restricted and steerability is maintained.
  • a length of between 5 cm and 60 cm proved its worth.
  • they are disposed in the rear or front area.
  • each skid 38 consists of a cross bar 39 , from which the blade edge 40 projects.
  • a controllable central skid (in the transverse center) may form a skid triangle with the other two fixed skids, e.g. two skids near the bow on the tube bodies and a central skid on the stern plate H.
  • the control skid that is located in the transverse center is coupled to the control of the lateral rudder 27 .
  • the control skid may be pressed towards the ice surface by means of a spring force in order to increase steerability, above its skid it may also be designed as a plane paddle in order to be able to implement steering in water.
  • Spring bias and a shaping that forms slide-on surfaces ensure sliding onto an ice surface and/or the driving over ice floes or the like.
  • skids 38 The fastening of skids 38 is implemented by means of clamping using the tensions formed on the tube cover 35 during inflating of the tube bodies 1 and 2 .
  • clamping pockets 36 and 37 are affixed to the cover 35 , which encompass edges of the element 39 in order to press said element 39 firmly against the cover 35 , it being also possible that the plate element 39 is arched slightly upwards.
  • hooks 43 and 46 which encompass the edges of element 39 are provided in each case on longer shackles 41 , 44 , which are disposed in a side-by-side relationship and whose end portions 41 a or 44 a are affixed to the tube cover 35 at 42 or 45 .
  • the shackles 44 , 41 are flexible. When the bodies 1 and 2 are inflated, the shackles are pulled in contradirectional directions due to a widening of the intermediate element 35 a of tube 35 and thus clamp element 39 firmly between the hook-shaped ends 43 , 46 .
  • the shackles 41 , 44 , 47 seem to cross each other in the front view, but are adjacent in the top view.
  • the vehicle is of a simple structure and has a comparatively low weight. It can be easily handled and accommodate additional equipment and persons. It is equally suited for driving on water and ice and, consequently, it can be used in a multi-purpose fashion, even under difficult conditions such as storms and thunderstorms.
