Definitions

  • the present invention relates to a light guiding system of the kind mentioned in the preamble of claim 1.
  • the invention furthermore relates to a method of providing such a shaft arrangement in a mounted condition.
  • roof windows are typically mounted in a roof surface of the roof, such that incident light falls into the room.
  • façade windows are typically applied as there is no immediate access to the roof surface, or only artificial light if the room has no access to an outer wall.
  • roof windows are typically installed in inclined or more or less flat roof surfaces, such roof windows provide for more light than a corresponding façade window and most often provide an unhindered view of the sky.
  • FR 2 939 460 shows a device with a rigid reinforcement whose upper portion and lower portion are respectively equipped with opposed frames.
  • a post connects the frames that are cooperated with openings.
  • a skirt is made of a flexible material, stretched on a circumference of the reinforcement between the frames, and fixed on the frames, where the skirt has an external surface on which a glass wool type insulating layer is adhered.
  • a film type transparent surface is made of plastic or glass.
  • the flexible material is a textile support and a coating layer i.e. polymer or anti-static material. The film type transparent surface extends inside the reinforcement.
  • a skylight structure that is sealed at the room ceiling rather than at the roof membrane is provided.
  • the structure includes a sealed light-diffusing panel attached to the ceiling, a light tube to channel light from the roof membrane to the light-diffusing panel, and a curbless roof membrane structure.
  • the light tube is constructed on-site using lengths of light-reflective material and special fastening means that provide great versatility in negotiating obstructions encountered in the space between the roof and ceiling.
  • the light guiding system By forming the light guiding system of a plurality of non-coherent parts, a large degree of flexibility and cost-efficiency is achieved, since in principle any cross-sectional shapes and lengths of the light guiding system may be accommodated.
  • the configuration of the shaft arrangement may in principle be carried out independently of the configuration of other components of the light guiding system, including for instance a roof module and a ceiling module, depending on the field of application of the light guiding system, the distance between the ceiling and the roof, and of any inclination of the roof surface.
  • the shaft provided by the sections of the shaft arrangement in the mounted condition of the light guiding system defines a general longitudinal direction extending between the roof and a ceiling or inner wall of a building.
  • the longitudinal direction may be perpendicular to one or both of the roof and the ceiling or inner wall, but it is also conceivable that the longitudinal direction forms an angle other than 90°.
  • a transverse direction of the shaft is defined as perpendicular to the longitudinal direction.
  • each part of said plurality of parts comprises two opposing first and second side edge portions, and wherein the first side edge portion of one part is adjacent to the second side edge portion of a neighbouring part in the mounted condition of the shaft arrangement such that the side edge portions are:
  • the light guiding system may in principle be used wherever there is a need for guiding light from one location to the other, but is particularly advantageous when, in the mounted condition, the light guiding system is configured to provide a light conduit between a roof of a building and an interior building room with a ceiling, the shaft arrangement of the light guiding system extending between a top at the roof and a bottom at the ceiling.
  • the top of the shaft arrangement is, in a presently preferred embodiment, connected to a frame at the roof and/or the bottom of the shaft arrangement to a frame at the ceiling.
  • a frame renders the connection of the shaft arrangement to the roof and/or the ceiling easier, and also provides stability to light guiding system during installation and in the mounted condition.
  • the configuration of the ceiling module may be chosen to form only a single frame in the ceiling, thus forming a base for the shaft arrangement but being otherwise open, leaving an unimpeded view to the roof module through the interior of the shaft.
  • an opaque panel may be mounted in the frame, thus admitting light into the interior room.
  • the ceiling module comprises a pane, preferably an insulating pane
  • the ceiling module of the system has been found to insulate the interior very efficiently from the loft in a comparably cheap manner. This is of particular advantage if the shaft arrangement runs through a not well insulated space. In case there is no ceiling module, or a ceiling module with no insulating pane, insulation surrounding the shaft arrangement is typically provided for.
  • the light guiding system may in principle be used for forming shaft arrangements of an arbitrary cross-sectional shape, it is presently preferred that the cross-sectional shape of the shaft arrangement in the mounted condition is substantially rectangular. This makes it possible to fit for instance standard roof windows of a variety of sizes at the top and/or bottom of the shaft arrangement, i.e. in the roof and/or in the ceiling.
  • the light guiding system may thus be seen as providing an add-on kit to supplement a product range.
  • the number of parts in the plurality of non-coherent parts may thus be two, three or four to form four sections of the shaft arrangement in the mounted condition. Of the plurality of parts, two, three or four parts may comprise a piece of cloth of a flexible cloth material. In the finished shaft arrangement, the parts of flexible cloth material thus constitute two, three or all four sections.
  • the cross-sectional shape of the shaft arrangement in the mounted condition may be non-uniform, preferably diverging, from the top to the bottom. This provides for the possibility of having a large incidence of natural light even from a relatively small opening in the roof, the shaft arrangement thus forming a pyramidal frustum shape in the mounted condition.
  • the shaft arrangement does not necessarily fulfil the requirements to a geometrically picture-perfect rectangle in cross-section, but a slight rounding at the edges is foreseen as well. Similarly, the edges may be slightly curved without deviating from the fundamental principles underlying the invention.
  • the roof light system according to the invention is applicable to a variety of configurations of the roof module, the shaft arrangement and the ceiling module.
  • a method of providing a shaft arrangement of a light guiding system according to claim 11 is provided.
  • a mounted light guiding system 1 is shown.
  • the light guiding system 1 is mounted in a roof structure of an inclined roof generally designated 2 within a framework of trusses 21, 22, 23, 24, counter-battens 25, battens 26 and a vapour barrier 27.
  • the trusses 21, 22, 23, 24 form, in a manner known per se , the load-bearing structure of the roofing (not shown) and the counter-battens 25 are arranged in parallel to the trusses, either on the same line as the trusses or offset therefrom.
  • the battens 26 of the roof 2 are arranged perpendicularly to the counter-battens 25, yet the arrangement thereof can also be in any other plane direction.
  • the light guiding system 1 can be mounted centrally in the roof 2, as shown in the drawing figures, or at the top edge of the roof 2, at the lower part of the roof 2 or at the outer edges of the roof 2. There may be more than one light guiding system 1 installed in the inclined roof 2.
  • the light guiding system 1 is here shown installed in an installed roof 2 as will be described in further detail below.
  • the light guiding system 1 is also applicable to flat roofs, however.
  • the light guiding system 1 is configured to provide a light conduit between the inclined roof 2 of a building and an interior building room 3 with a ceiling 31.
  • the light guiding system could in principle comprise only a shaft arrangement with a plurality of shaft sections.
  • the shaft arrangement is generally designated 6.
  • a plurality of at least two, here four, non-coherent parts 601, 602, 603, 604 is provided.

  • a mounting bracket 44 is shown for installation of the roof module 4 on battens 26 of the roof 2.
  • the mounting bracket 44 might be configured to fit to battens 26 of different sizes and comprise holes for protruding means such as screws or other attachment means.
  • the roof module pane 42 may comprise any at least partially translucent panel element of a suitable material.
  • the roof module pane 42 comprises a glazing unit with one or more clear sheets of glass or a plastic material.
  • the roof module plane is substantially parallel to the surface of the roof 2.
  • the light guiding system 1 in the embodiment shown, further has a ceiling module 5 with a ceiling module frame 51.
  • the ceiling module 5 is also provided with a ceiling module pane 52.
  • the ceiling module frame 51 defines a length LCM and a width WCM of the ceiling module 5 in a ceiling module plane and is configured to be mounted in the ceiling 31, e.g. connected to the trusses 21, 22, 23 and 24. In the mounted position, the ceiling module plane is substantially parallel to the ceiling 31.
  • the light guiding system 1 comprises the shaft arrangement 6, which in the embodiment shown extends between the roof module 4 and the ceiling module 5.
  • the shaft arrangement 6 is defined by two side sections 61, 62, a first end section 63 and a second end section 64.
  • the first part 601 further has a first side edge portion 613 and a second side edge portion 614 such that the first side edge portion 613 is intended to be positioned adjacent to a second side edge portion 634 of a neighbouring part, i.e. here the third part 603 configured to form end section 63.
  • the second side edge portion 614 is intended to be positioned adjacent to a first side edge portion 641 of the fourth part 63.
  • the end sections 63, 64 and the side sections 61, 62 in the mounted state form the shaft arrangement 6 of the light guiding system which in the embodiment shown extends between the roof module 4 and the ceiling module 5.
  • the configuration of the shaft arrangement 6 may be chosen in any suitable manner as long as at least two of the sections 61, 62, 63, 64 of the shaft arrangement each comprises a piece of cloth, the cloth being of a suitable flexible cloth material.
  • suitable materials including for instance plastic materials.
  • tightening means are provided to hold the section or sections comprising a piece of cloth of flexible cloth material between the roof module and the ceiling module in a stretched state in the mounted condition, i.e. in the longitudinal direction of the shaft formed by the shaft arrangement 6.
  • Such tightening means may be present at several positions of the components of the light guiding system, typically at the roof module, the ceiling module and/or in the shaft arrangement itself.
  • tightening means comprising tightening elements 45, 55, 56, 65, 66 to be described in further detail below are provided to hold the two side sections 61, 62 between the roof module 4 and the ceiling module 5 in a stretched state.

  • the mounted condition includes such conditions where the roof module 4 is positioned in the roof 2, the ceiling module 5 in the ceiling 31 and the shaft arrangement 6 extends between the roof module 4 and the ceiling module 5. Not all elements need be in their final conditions for a condition to qualify as a mounted condition.
  • the supply condition encompasses the conditions which the parts of the kit for forming the light guiding system can have during transportation and assembly.
  • section is generally to be understood broadly.
  • the sections of the shaft arrangement are to be considered separate units which may or may not be joined at their respective side edges.
  • adjacent side edge portions of neighbouring parts may have the following configurations in the mounted condition:
  • adjacent side edge portions form corner edges 6a, 6b, 6c, 6d of the shaft arrangement 6 in the mounted condition.
  • each section extends substantially between the roof module and the ceiling module. It is however conceivable to provide the light guiding system with a shaft arrangement which has a shorter length, for instance being connected to an adapter piece forming part of a frame at the roof and/or the ceiling. It is furthermore common to all of the embodiments that each individual section may be tailored to the specific configuration of the roof light system. While the two side sections are typically adapted to have the same shape and dimensions, the shape and dimensions are typically different from the shape of the end sections. The end sections, while being both rectangular, typically have different lengths as they need to be adjustable to different heights at the depending on the roof inclination. The only exception is a configuration in which the roof module and the ceiling module are parallel to each other and the side sections are rectangular, that is when the shaft formed by the shaft arrangement is a prism.
