Description

(1) Following the brief indication above of the present invention, herein below are more detailed description of a possible embodiment is provided, to which the present invention is by no means limited or restricted since the invention is only and exclusively delimited in the appended independent claims. The following description of a possible embodiment is to be taken in conjunction with the accompanying drawing, in which the same or similar features, components and elements can be designated with the same or a similar reference numbers, even though distinct embodiments can be referred to, and wherein:

(2) FIG. 1 shows a side view of a yacht according to the present invention;

(3) FIG. 2 shows a more detailed view in section II-II in FIG. 1;

(4) FIG. 3 shows an exploded perspective view of an alternative embodiment of a cladding element in addition to the embodiment of FIG. 2;

(5) FIG. 4 shows a cross sectional view in the direction of arrow IV in FIG. 3 of the cladding element in assembled state; and

(6) FIG. 5 shows a perspective side view and an enlarged detail of the embodiment of FIGS. 3 and 4.

(7) In FIG. 1, a side view is shown of a yacht 1, comprising a superstructure 2 on a hull 3. Of the hull 3 only a portion above waterline 4 is shown. The portion of hull 3 above waterline 4 is provided with cassette like cladding elements 5, to be described in more detail below, referring to FIG. 2. The cladding elements 5 are shown to have essentially triangular circumferential shapes, but other shapes are naturally also possible, such are square, rectangular or honeycomb shaped, at cetera. The cassette-like cladding elements 5 are shown to cover a side of the hull 3 for essentially the most part, but not all of the side of the hull 3. In alternative embodiments the light emitting cassette-like cladding elements 5 could cover less of the side of the hull 3, or even more. For instance the cladding elements could further be arranged on or against (portions of) a superstructure or a mast. The cassette-like cladding elements 5 are configured to emit light of at least one colour, as will be described in more detail below in relation to FIG. 2.

(8) As shown in view of FIG. 2 of a side cross sectional view along line II-II in FIG. 1, the ship's hull 3 has an indentation or recess or the like, defined by a shoulder 6 for a cladding element 5 to be supported on. Higher up on hull 3 a further cladding element 5 is arranged. The cladding elements 5 are designed to cover surface of the hull 3 in a closely fitting manner, so as to appear unitary already from a short distance, at least with respect to light emitted from the cladding elements 5. This is to say that preferably no dark lines corresponding with transitions between cladding elements 5 are visible, already at a short distance from hull 3 or from the entire yacht 1 in FIG. 1.

(9) Cladding elements 5 are preferably configuredalthough alternatives will be readily evident to the skilled readerfrom a base 7, that can be manufactured from any material suitable to withstand the harsh conditions at sea, such as metal, in particular aluminium, composite material, plastics, and/or the like, in so far as a sufficiently sturdy base for the cassette-like panels or cladding elements 5 can thereby be formed. The base 7 forms a carrier for light sources 8, which are preferably LED light sources in view of their durability, power consumption and light efficiency, although other types of light sources will be evident to the skilled reader, even if such other types of light sources are less durable or less economical or less efficient than LED light sources. In view of heat dissipation for heat generated by the light sources 8 or LED's, base 7 is preferably manufactured from a material having a sufficient heat guiding capacity, such as a metal or even aluminium.

(10) The light sources 8 can be connected to a power source (not shown) via cables 9, that protrude through hull 3 at a safe height above waterline 4 or can protrude through watertightly closed passages at arbitrary height on hull 3. It is even possible to arrange sockets in or on hull 3 and arrange plugs on the cable 9 to allow the LED's 8 to be connected to a power source in a plugged manner. Preferably, cables 9 connect via a control 10 to a power source, such as an on-board generator, where control 10 can be configured to determine which of the panels or cladding elements 5 are powered (more in particular the LED's of which the cladding elements 5) and/or even which LED's 8 are to be driven, if the LED's come in different colours or if any LED's can be driven in multiple colours. For instance the control can be used to determine that a selected on of the cladding elements needs to be disconnected (for replacement or maintenance) so that such tasks can be performed without any risk to a maintenance crew.

(11) The light sources 8 are thus arranged on base 7 and are moreover encapsulated in an assembly of base 7 and a transparent layer 11. The transparent layer 11 may be manufactured from a plastic or a resin, again preferably suitable to withstand harsh conditions and influences at and of the sea. For instance the transparent layer 11 can be a material commonly referred to as SP-Gurit 115 or 320. The invention is however not limited to this specific choice of material. The transparent material of or for transparent layer 11 can have been cast on base 7 after the LED's 8 are first arranged thereon and connected to at least the cable 9.

(12) On an outside oriented surface of the transparent layer 11, a diffuser layer 12 can be arranged. For instance a composite diffuser panel can be employed to embody such a diffuser layer 12. Thereby, light emitted by the light sources 8 (for instance but not exclusively LED's) can be diffused to provide a homogenous optical effect.

(13) Additionally, a white gel coat top layer can be provided for diffuser layer 12, for which clear resin can be employed to enhance the resistance of cladding elements 5 against the elements of wind and sea, and for instance such a layer or the diffuser layer 2 can comprise some additive or the like to provide UV protection.

(14) Further additionally or alternatively a top coat paint can be arranged, to give the impression of a normally white, grey or black hull 3 (or any other colour considered conventional) so that when the lights sources 8 are switched off (for example in the day time) the yacht does not give an impression of any special feature; only when the sun goes down and the light sources are lit through the controller 10 is the special nature of yacht 1 according to the present invention revealed. Such a top coat paint should be light transmitting, and a material commonly referred to as clear awlgrip or a similar coating can be employed.

(15) Yet further the circumferential sides of the cladding elements 5, more in particular the circumferential sides of the transparent layer 11, may be covered with a reflecting layer 13, to ensure as much as possible of the light from the light sources 8 is actually emitted out of the cladding elements 5. Moreover, transitions or joints between cladding elements 5, such as in the insert portion in FIG. 2, may be sealed with a joint 14 to ensure watertight mutual connection of the cladding elements 5. For this a material commonly referred to as a sikaflex joint may be employed.

(16) Preferably the cladding elements 5 abut closely against the curvature of hull 3. For this, base 7 may be curved in correspondence with hull 3. Additionally, the thickness of the cladding elements is preferably uniform over the area thereof, in order to secure a uniform emission of light from the cladding elements. However, according to the invention, the thickness of the cladding element does not necessarily need be constant over the entire cladding element, as clear from the representation of FIG. 2, especially by comparing this thickness at several heights along hull 3 in FIG. 2. It is considered desirable to have cladding elements 5 abut closely to or even have full contact with the ship's hull 3. Thereby, also hull 3 can contribute to heat dissipation in relation to heat from light sources 8. Moreover, cladding elements 5 are thereby better apt to withstand influences from the sea and wind, and remain well fixed to hull 3. Optionally, a filling material can be employed to fill any space between hull 3 and cladding elements 5, for instance a glue or adhesive, which may in itself function to arrange the cladding elements 5 to hull 3. Filling materials can also be cork or foam, or the like.

(17) To secure cladding elements 5 to hull 3, use can be made of brackets 15 which may be welded or bolted onto hull 3. Additionally or alternatively, the aforementioned adhesive or glue 16 may be employed to attach cladding elements 5 to the ship's hull 3. The cladding elements may comprise a shoulder or flange, as exhibited in FIG. 3 at the right side in that drawing, with optionally through holes therein for mounting cladding elements to a supporting surface, such as the hull of the ship, yacht or other vessel or a stationary object.

(18) At the back of lowermost cladding element 5 in FIG. 2 a further fixing 17 is shown to secure cladding element 5 to hull 3, as well as a seal 18.

(19) In an alternative embodiment relative to cladding elements 5 of FIG. 2, FIGS. 3, 4 and 5 show that a cladding element 20 can be composed from a foundation layer 21, on which a compartment layer 22 is accommodated. The foundation layer 21 is preferably designed for at least one of chemical and mechanical connection to a carrying surface such as a hull of a yacht, boat or ship. Preferably further, the foundation layer 21 is suitable to withstand deformation resulting from ship movements. For instance the foundation layer may be sufficiently rigid to strengthen the hull of a yacht, or be flexible enough to bend with such movements. However, the latter option would pose challenges on the overlying structures. Such movements may be generated by the swell of the sea or any other body or water, but likewise temperature fluctuations may cause extension and crimp, which is also included in the meaning of the expression of movements, even in fields of applications where claddings according to the invention are mounted on or against stationary objects (unlike yachts, that sail).

(20) The compartment layer 22 comprises ribs 23, which extend from the foundation layer 21 to an upper layer 24 of the compartment layer 22. The ribs 23 extend in the shown embodiment away from the foundation layer 21 under an essentially straight angle to define there between seats 25 for light sources 26. From the seats 25, the ribs 23 extend obliquely towards the upper layer 24, to define diverging shapes in the direction towards the upper layer 24 of the compartment layer 22. Alternatively, the ribs may extend to the upper layer under an essentially straight angle from the foundation layer 24, without the diverging shape between the seats 25 and the upper layer 25. The angle of the ribsif providedmay be chosen or more preferably designed in conjunction with a distance from the light sources 26 to diffuser layer 27 (see below). With the aim of achieving homogeneous light output, the portions of the ribs 23 above the seats 25 may extend at an angle between 90 and 30, more preferably between 45 and 60. The actually chosen/designed angle will also depend on the light scattering/diffusing properties of the ribs 23.

(21) Light sources 26 are, in the shown embodiment, arranged on the seats 25 in series extending through trough-like elongate spaces, defined by the ribs 23. The light sources may be any type of LED light sources, such as RGB, W, WW, CW, DW, O-led or the like. Any other type of source may also comply with the requirement of low power consumption, high efficiency and maximum light output and ability to be diffused at short distance from the sources and/or to be mounted closely enough in view of for instance heat development to achieve the homogeneous external lighting of the object, to which claddings 20 are mounted.

(22) The lights 26 may be embedded in a resin or plastic, to enhance the resistance thereof to for instance sea water, in case the cladding elements spring a leak, or water penetrates into the cladding elements in any other arbitrary but undesired manner. These lights may alternatively also be arranged directly on seats 25, but as a further alternative reference is made here to a configuration, wherein lights 26 are accommodated in cylindrical, square or otherwise shaped tubes, the ends of which may be sealed closed to shield the lights 26 as an additional protection against salt water or other potentially harmful influences. Such a seal is preferably removable to allow for maintenance and/or LED 26 replacement.

(23) In this or an arbitrary other configuration according to the invention, the compartment layer 22 in assembly with the underlying foundation layer 21 and with the overlying upper layer 24 of the compartment layer 22, the other layers thereon (see below) provide for excellent resistance against for instance impact, pull forces and pressures. For example, PMMA can be used as a material for manufacturing and/or assembling parts and/or components of the cladding elements. If such PMMA parts and/or components are required to be assembled using adhesive or glue, then it should be considered that specially appropriate glue or adhesive may be necessary, and this is naturally also a consideration for other plastics or materials in general.

(24) It is noted that the seats 25 define cross connections between the ribs 23, increasing the strength of the resulting construction. Further, strength of the claddings may be increased by including bulkheads (not shown), which may extend transversely of the trough like light source accommodations, for instance between each pair of neighbouring light sources 26 or with each pair of bulkheads enclosing for instance two, three, five, or any other suitable number of light sources 26. Ribs may additionally or alternatively be arranged to cross each other and be connected at such crossings, to define a strengthening matrix or web, in particular (though not exclusively) with straight ribs.

(25) Preferably, the claddings 20 cover as much area of a surface against which the claddings are to be mounted, such as the hull of a ship. The construction of FIGS. 3, 4 and 5 allows for coverage of huge areas, whilst maintaining strength and integrity.

(26) For fields of application on for instance a yacht or boat, the claddings are preferable further inert to seawater and occasionally relatively extreme temperature fluctuations. To this end suitable material may be chosen, which choice of material is considered to lie within the reach of any person skilled in the relevant art with a regular knowledge level.

(27) In a possible embodiment, the ribs 23 may have reflecting or defusing properties in relation to light emanating from the light sources 26. Likewise, the foundation layer 21 may have reflecting properties and/or even defusing properties. In addition or alternatively, the upper layer 24 of the compartment layer may have diffusing properties. In addition or alternatively, on the upper layer 24, a light diffusing layer 27 can be provided, which in turn can be covered by a top layer 28. A bonding layer 29 may be provided between the diffusing layer 27 and the top layer 28. Likewise, a bonding layer 30 may be provided between the upper layer 24 of the compartment layer 22 and the diffusing layer 27. In alternative embodiments, one or more of the layers 24, 27, 28, 29 and 30 can be integrally formed. Most preferably, diffusing properties will be realised to scatter light from the sourced 25, as it is emitted out of the cladding 20. The top layer 28 can comprise one or more of: a translucent foil, such as 3M IJ3630-20 on for example a 1370 mm wide roll; and a scratch and graffiti resistant protective foil, such as 3M VentureShield on a 1500 mm wide roll. These or other foils may contribute to the desired degree of diffusion of light from the LED light sources 26. A colour could even be realised in or by the foils, such that light from sources 26 can seem to have another colour than white from a distance from the ship or yacht.

(28) Electrical guides 31 can be provided through the compartment layer 22, i.e. between the foundation layer 21 and the upper layer 24 of the compartment layer 22, to enable supply of electrical power to the light sources 26.

(29) The top layer 28 is essentially determinative for the exterior appearance of the cladding 20 according to FIGS. 3, 4 and 5. Consequently, measures can be taken as described above to influence this exterior appearance of the cladding 20, such as a coating on the top layer 28 or with the coating as a backing layer of the top layer 28, or a top layer 28 formed by a coating, to simulate or maintain the normal appearance of the object, such as a yacht, to which the cladding is applied, i.e. under daylight or externally illuminated circumstances. However, in the dark, when the light sources 26 are activated, the assembly of layers must be able to pass light outward through the diffusing layer 27 and the top layer 28 in order to provide the sought effect of outward illumination of this object, as indicated also herein above. To achieve this effect, the top layer 28 can be manufactured from a glass or any transparent composite material, especially but not exclusively if a coating is then applied on or behind the top layer 28 to influence the appearance of the cladding in general and of the top layer 28 in particular.

(30) The light diffusing layer 27 diffuses light from the internal light sources 26. Moreover, the transparent or translucent properties of the assembly of the top layer 28, the diffusing layer 27 and the top layer 24 and in particular of the diffusing layer 27 must preferably be such, that the internal configuration of the compartment layer 22 with the ribs 23 and a light sources 26 remains essentially invisible from the outside. Likewise this assembly of layers and in particular the light diffusing layer 27 preferably exhibits a UV filtering capacity to protect underlying composites materials against ageing.

(31) In the embodiment of FIGS. 3, 4 and 5, the compartment layer 22 defines adjoining cavities or accommodations for light sources 26. The light sources 26 are arranged on or in seats 25 and the ribs 23 and the seats 25 of the compartment layer 22 can be or are preferably formed from any one or more than one of: composite material; metal; or other plastics, depending on the field of use. Compartment layer 22 can extend over the entire length or width of a cladding 20, or can be divided into separate components, dividing the length or width of the cladding 20 into a plurality of separate compartments.

(32) As shown in FIG. 5, cladding 20 may be provided with a cast side wall 32. The cast side wall 32 may alternatively or additionally be prepared from thermoplastic material or the like, forming a semi- or fully permanent seal of open sides of the cladding 20, in particular of the compartment layer 22 thereof, to close the cladding against inflow of water, such as sea or rain water. In an embodiment, where the sealing side wall 32 is semi- or fully permanent, access may at times be desired for maintenance of the light bulbs 26 or the seats 25 or the ribs 23, et cetera. In this case, the sealed sides may need to be forcefully opened, possibly inflicting damage thereto, for instance using a tool, such as the schematically represented screw driver 33. However, the sides of portions thereof, that are broken open for maintenance or replacement of light sources 26 can be closed or sealed again in much the same manner as during original manufacture of the cladding 20, for instance by casting a setting material on said sides, or by applying molten thermoplastic material thereon. Even dipping sides of the cladding 20 in a bath of resin or thermoplastic material is optionally possible.

(33) Even though the cladding of FIGS. 3, 4 and 5 has been described in conjunction with the field of application of yachts, where the claddings are mounted to the hull of a boat, ship or yacht, it should be noted here that the cladding may very well also be usefully employed in the fields of:

(34) swimming pools and in particular side walls and/or bottoms thereof, as well as on surrounding structures, like a pool house or paths or pavements there around;

(35) bridges, for example on bridge decks and/or against uprights and/or stairs and/or walls;

(36) ornamentation of public spaces and public structures, like street furniture, roads, pavements, stairs, 3-D structures like art, separation structures, walls;

(37) building facades; and

(38) the like. The cladding elements could even be employed as floor elements, for example to define a dance floor, for which the foundation layer would preferably be flat.

(39) Further, the claddings may be produced in any appropriate shape or form, such as rectangular, triangular, honeycomb shaped, square, circular, elliptical, star shaped, amoebae shaped, banner shaped, et cetera. The claddings 20 may even be formed during production to exhibit a curvature in correspondence with a base surface, such as a hull of a ship, against, on or to which the claddings are intended to be mounted. In addition it is noted that claddings according to the invention are preferably such that ingress of dust, moisture and liquid is restricted. For such properties Ingress Protection (IP) codes or ratings have been developed in the art. An overview can be found at for example: http://en.wikiedia.org/wiki/IP_Code. For the present exemplary field of use of a cladding on a hull of a yacht, an IP rating may suffice of IP68 (dust tight and able to withstand ingress of harmful quantities of water when immersed beyond 1 meter) or the even lower rating IP67 (same criteria for product immersed up to 1 meter). For other fields of use; suitable rating can be determined, based on the specific circumstances and potentially harmful influences in such another field of use.

(40) From the foregoing description of a possible embodiment of a yacht according to the present invention it will be abundantly clear that the invention is by no way to be interpreted in a limited sense as restricted to any of the particular features of any embodiment as described above. Instead, limitations on the present invention only result from the definitions of the invention in the appended claims, in particular the appended independent claims.
