Definitions

  • the present invention relates to small scale shipbuilding and can be used in design of a floorboard for an inflatable boat, and to an inflatable boat having such a floorboard.
  • floorboard means demountable flooring to be arranged in an inflatable boat on its bottom.
  • Floorboard serves to add lengthwise and lateral rigidity to inflatable boat hull as well as to provide stable footing for passengers. Most of floorboards are made demountable, composed of sections positioned across the symmetry axis of the boat. Floorboard sections are made of plywood, aluminium alloy or polymer material. The floorboard is squeezed between the bottom of the boat and the inflated sides. (ref.: Korolev A.N., Zhokhov V.P. Inflatable boats. L.: Sudostroenie, 1989, pages.83-84 ).
  • Patent RU 136,413 U1 B63B7/08 published 10.01.2014, discloses a design of an inflatable boat which includes a hull made of elastic material with inflatable sides that are interconnected by elastic bottom, lengthwise stringers and a demountable floorboard comprising a front section, a central section and a stern section, said sections are provided with connecting profiles for releasable connection, disposed perpendicular to longitudinal symmetry axis of the boat.
  • the boat disclosed in patent RU136413U1 can be disassembled using the following method only, which is determined by said floorboard design.
  • the above technical problem also determines a strict order of actions a user should follow to assemble and disassemble an inflatable boat.
  • a beginner for example, can forget inserting the floorboard sections before inflating the sides of the boat, thus he/she will have to deflate the boat sides again to install the floorboard sections.
  • Said floorboard comprises a front section, a central section and a stern section, said sections are provided with connecting profiles for releasable connection.
  • the central section comprises one or more tiers, each tier being made of segments shaped, when seen from above, as a rectangular trapezoid, whereby said segments are being interconnected at an acute angle to longitudinal symmetry axis of the floorboard, and the bases of said rectangular trapezoids are perpendicular to the symmetry axis of the floorboard when assembled.
  • a drawback of the closest prior art design is that the connecting profiles of the central segment sections have a slit at locations of joint of the central section tiers to each other as well as to the stern section and the front section, which is clearly seen in the drawings enclosed to the patent RU 169,992 U1 . Therefore, the closest prior art is characterized by complexity of fastening the tiers of the central section both together and to the stern section and the front section, as the connection of the adjacent sections of the floorboard as such is performed by interconnection of three connecting profiles, that is, user has to connect the connecting profile of the front section, as well as the connecting profile of the stern section, with the transverse connecting profile of each of the segments of one tier of the central section. At the same time the connection of the two adjacent tiers of the central section is performed by simultaneous connection of four transverse connecting profiles, which apparently may result in more complexity and inconvenience for the user.
  • the object of the present invention is simplification of design of fastening the stern section and the front section to the segments of the central section of the floorboard with simultaneous increase of its rigidity, strength and reliability.
  • a demountable floorboard as defined by claim 1 is provided.
  • the dependent claims show some examples thereof.
  • An inflatable boat according to the present invention is defined by claim 7.
  • a demountable floorboard for an inflatable boat comprising a front section, a central section and a stern section, said sections are provided with connecting profiles for releasable connection.
  • the central section has one or more tiers, each is made of segments shaped, when seen from above, as trapezoids, for examples as rectangular trapezoids, wherein an acute angle at one of their corners is provided in a preferred embodiment.
  • the floorboard segments of the central section tiers are made in such a way that the bases of said rectangular trapezoids are parallel to the symmetry axis of the floorboard when assembled.
  • the slit of the connecting profiles is disposed outside the areas of contact of the central section of the floorboard to the front section and the stern section of the floorboard, and therefore the connecting profiles of the front section and the stern section are easier to connect to the connecting profile of the central section. Similar advantage is maintained during the process of disassembly of the floorboard and its removal from an inflatable boat.
  • An acute angle is particularly an angle of less than 90 degrees.
  • said segments shaped as trapezoids may be provided with connecting profiles which enable their releasable interconnection.
  • Configuring the segments of the central section of the floorboard as trapezoids, like rectangular trapezoids, for example, and/or with an acute angle at one of their corners, with the parallel sides of these trapezoids (that may be pre-inserted into stringers) adjoining the boat tubes (sides), allows easy installation and removal of the floorboard sections into/from an inflatable boat with boat sides fully inflated, and even when deflated. With this, there is no slit of lateral connecting profiles in the areas of interconnection of the tiers of the central section, and their connection to the front section and the stern section, and thereby the procedure of the floorboard assembly and disassembly is simplified and at the same time rigidity, strength and reliability of the floorboard is increased.
  • the segments are shaped as trapezoids, wherein the respective trapezoid may be free of any 90-degree angle or may have exactly two 90-degree-angles.
  • the segments shaped as trapezoids or rectangular trapezoids, respectively have a shape different from a rectangle and/or square.
  • each of the connecting profiles interconnecting the sections is made as a single piece continuously extending along the whole joint.
  • the parallel sides of the central section segments may be provided with side profiles.
  • Fig. 1 , 2 have the following reference numbers:
  • the present invention can be successfully embodied in a design of a floorboard containing a front section 1, a central section 2 and a stern section 3, said sections are provided with connecting profiles 4.
  • Central section 2 of the floorboard is made composed of segments 8 shaped, when seen from above (projection onto a horizontal plane), as rectangular trapezoids with an acute angle at one of their corners, said segments can be releasably interconnected by means of connecting profiles 4 at an angle ( ⁇ ) to longitudinal axis (S 1 S 2 ) of symmetry of the floorboard.
  • the bases of said rectangular trapezoids are parallel to axis (S 1 S 2 ) of symmetry of the floorboard, which ensures reliable rigidity and strength of obtained flooring even under significant lateral loads as well as enhancement of general reliability of the structure.
  • each of the connecting profiles 4 which interconnect the sections is made as a single piece continuously extending along the whole joint, which means that each of the interconnected connecting profiles of adjacent floorboard sections is made as a continuous single piece connecting profile 4.
  • said segments 8 of the central section may be provided with side profiles 6 which are inserted into lengthwise stringers 5 of the boat when assembling the floorboard.
  • Lengthwise stringers 5, connecting profiles 4 and side profiles 6 may be made of e.g. aluminium alloy or polymer material.
  • Segments 8 may be made of e.g. waterproof multi-layer plywood, polymer material or aluminium alloy.
  • central floorboard section may be composed of several tiers; at that, each tier is made of segments 8 or 9, preferably two segments 8 or 9 which are shaped, when seen from above, as rectangular trapezoids with an acute angle at one of their corners. Segments 8 and 9 of tiers of the central section 2 are releasably interconnected as well as releasably connected to the stern section 3 and the front section 1 by means of connecting profiles 4 at right angle to longitudinal axis (S 1 S 2 ) of symmetry of the floorboard.
  • the floorboard is placed onto the elastic bottom of the boat regardless of inflation degree of the sides (fully inflated, underinflated or fully deflated) as follows.
  • Front section 1 is pushed forward into the fore part of the boat bottom. Then, the lengthwise stringers 5, if any, are placed between the boat side tubes and the bottom of the boat. After the lengthwise stringers 5 have been mounted, one of segments 8 of one tier of the central section 2 is mounted, wherein the parallel bases of the rectangular trapezoid are contacting the longitudinal stringers 5. The next segment 8 of this tier of central section 2 is likewise pushed in along the line of connection, which is set at an angle ( ⁇ ) to longitudinal axis of symmetry of the floorboard. With segment 8 fully pushed in, the segments 8 of one tier of central section 2 become wedged against the lengthwise stringers 5, which in turn abut against the sides of the boat.
  • angle
  • the central section 2 of the floorboard can include one or more tiers, number of which depends on the length of inflatable boat. Then the stern section 3 is mounted, thereby segments 8 and 9 of the central section 2 are wedged, and the front section 1 is pressed.
  • Demounting of the floorboard is carried out in reverse order regardless of inflation degree of the sides (fully inflated, underinflated or fully deflated).
  • Patent search that was carried out has proved international novelty and inventive step of the present invention.
