Definitions

  • the invention relates to a skylight for pitched roofs.
  • the invention provides a skylight for a pitched roof, comprising a first part having an interior placement member to be placed against the inner roof and having a first tube member that allows light to pass through to extend through the roof, as well as a second part having an exterior placement member to be placed against the outer roof and having a second tube member accommodating the first tube member, wherein the first tube member is adjustably accommodated in the second tube member.
  • Assembling the skylight in a pitched roof can easily take place by having both parts extend into each other from the inside and the outside, respectively, wherein the thickness of the roof surface (presence and thickness insulation layer) is of no importance and need not be known beforehand.
  • the first tube member extends entirely through the roof, into or past the exterior placement member.
  • the first tube member may be accommodated in the second tube member so as to be freely slidable, so that deformations or changes in the thickness of the roof surface (for instance by adding a layer at the inside) occurring later, can be allowed without changing the skylight.
  • first tube member extends beyond halfway the second tube member, a double-walled tube structure that may be heat-insulating, is realised over a large length.
  • the second tube member has a tube portion extending in exterior roof direction from the exterior placement member, wherein the first tube member preferably is capable of extending into the said tube portion.
  • the second tube member then extends beyond the (sloping) roof surface and provides guidance to the light from outside.
  • Guiding light to the inside is further enhanced when the first tube member at the inner surface is covered with a light-reflecting layer.
  • the interior placement member preferably forms a placement flange that can be provided on the inner boarding.
  • the first tube member may have a centre line, which with the placement flange encloses an angle of approximately 90 degrees or an inclined angle of preferably 45 degrees. In case of an inclined angle of 45 degrees a requirement is met for letting the first tube member extend in two directions from the roof surface, particularly horizontally and vertically, as desired when installing.
  • the second tube member may then have a centre line that is at an angle of approximately 45 degrees to the plane of the covering transitional part at the location of the first edge.
  • the first tube member may be provided with a circumferential sealing ring for engagement of the inner surface of the second tube member.
  • the sealing ring preferably is arranged at the outer end of the first tube member to keep cold air out as much as possible. This particularly prevents transport of warm air from interior roof areas to the outside, which in turn prevents condensation at exterior roof elements which in case of frost would result in icing which when thaw sets in might cause leakages.
  • the sealing is at the warm side of the structure, as a result of which internal condensation in the insulation is prevented.
  • the second tube member tapers, as a result of which small differences of the angle of inclination of the roof surface and the angle between the second tube member and the exterior placement member can be levelled to the eye.
  • the second tube member tapers with respect to the first tube member, so that an intermediate space can be formed which may be heat-insulating.
  • the conicity of the second tube member with respect to the first tube member may be a number of degrees, preferably between approximately 0-10 degrees.
  • Insulation is further enhanced when an inner wall is present in the second tube member, said inner wall running parallel to the outer surface of the first tube member.
  • the second tube member has a hollow circumferential wall that may be filled with heat insulating material.
  • the circumferential wall extends in interior roof direction to beyond the exterior placement member, particularly forming a tube portion extending to the inside, the heat-insulation at the location of the roof passage is enhanced.
  • At least one of the tube members may be provided with one or more plates of transparent or translucent material.
  • the plates may be disposed at the outer end of a tube member, preferably in the second tube member.
  • the plates are transverse, in particular almost perpendicular to the centre line of the tube members, so that a special light effect can be achieved, when the tube members extend horizontally and when the tube members extend vertically.
  • Insulation is enhanced when two plates are present which in between them define an air chamber.
  • Said chamber may be functionally connected to the cavity formed by the double-walled second tube member, to which end the chamber and the cavity of the hollow circumferential wall are situated substantially adjacent and parallel to each other. Both hollow spaces may be separated from each other by a small partition, yet they ensure a contiguous insulating space around the second tube member.
  • the exterior placement member forms a plate-shaped covering transitional part in a tile roof.
  • the covering transitional part may be provided with a provision for a counter flashing or something like that. Said provision may form a separate part that is attached to the covering transitional part.
  • the covering transitional part When in an area spaced from the edge opposite the first edge the covering transitional part is aligned with the area contiguous to the first edge with respect to a centre of the covering transitional part, forming the covering transitional part in a mould can easily be achieved by using one single mould for forming a covering transitional part suitable for horizontal positioning of the tube members and a covering transitional part suitable for vertical positioning of the tube members, wherein an insert is placed in the mould contiguous to the first edge or where ever else the area contiguous to the second edge may be formed.
  • the covering transitional part is provided with water guiding and/or sealing strips, such as foam strips, at the side edges.
  • Both tube members preferably have a, in cross-section, curved circumferential wall, preferably a circular wall.
  • the invention provides a skylight, particularly, yet not exclusively, a skylight as described above, provided with an illumination device having an illumination member, so that the skylight even when there is no natural light (at night) may fulfil a light providing function.
  • the illumination member is disposed in one of either tube members.
  • the illumination member preferably is disposed in the second tube member, preferably near its end.
  • the illumination member is placed near or contiguous to the inner side of the plates. Alternatively an extra plate may be used as light plate.
  • Dispersion of light is enhanced when the illumination member is circumferential, preferably following the inner surface, in which case the passage of natural light can remain unobstructed.
  • the illumination device comprises a LED and a light conductor, as a result of which low-voltage will suffice, which facilitates the connection.
  • the illumination member forms the light conductor, emitting the light.
  • the light yield to the inside is increased when at the outer side of the light conductor a reflector means is placed.
  • the illumination member comprises a transparent or translucent plate, of which a main surface, preferably the outer surface, is surface-treated for forming a pattern, wherein the plate edge is provided with a portion through which light, for instance LED-light is radiated into the plate.
  • the skylight 1 shown in figure 1 comprises an interior member 2 and an exterior member 3. Both members can be made of synthetic material, for instance by vacuum moulding or injection moulding, in the desired colour(s).
  • the interior member 2 comprises a placement flange 4 and a tube member 10 that may be separately made and connected to each other by means of a snap connection 41 that is not further shown.
  • the placement flange 4 has a circumferential edge 7 and a recessed inner portion 8, intended to be oriented towards the roof boarding and having a width varying over the circumference, so that the placement flange 4 is situated eccentrically with respect to the centre line S of the tube member 10.
  • the inner surface 9 of the placement flange 4 has a convex cross-section. Towards the connection 41 the placement flange 4 smoothly changes into a more or less conical collar 6.
  • the tube member 10 has a circular cross-section and an inner surface 50 covered with a layer of light-reflecting material. At the end of the tube member 10 a flexible sealing ring 11 is attached, having a sealing lip 11 a extending radially to the outside.
  • the exterior member 3 comprises a covering plate 5, intended to be placed against the battens of a pitched roof, parallel to the slope of said roof.
  • a notional line 18a is shown, above which a facultative strip 16 is situated, which is formed as one unity with the covering plate 5, and which when forming the covering plate 5 can be left out by filling the mould to be used.
  • Below the line 18a there is a more or less flat plate section 15, onto which elevations or ribs 19 have been arranged for guiding water and for reinforcement.
  • a lower edge 18b In the lower edge area there is a lower edge 18b, which in this case - instead of edge 18a- when being moulded has defined the end edge of the covering plate 5.
  • a flashing 40 is attached around the lower edge 18b by means of a clamping strip 17, which flashing is made of lead or a led-substituting material, that can be laid over a next tile, for substantially wind and watertight connection thereto.
  • sealing profiles for instance made of foam, can be placed at the side edges of the covering plate 5 and section 15.
  • a tube member 20 is formed as one unity with the covering plate 5, the tube member 20 having a circular cross-section and ending in a flange 30, forming a passage in said end, in which passage plates 31 allowing light to pass through (made of synthetic material or of glass, particularly transparent) have been placed.
  • An outer plate 32 and an inner plate 33 can be distinguished here, which in between them define a heat-insulating -and possibly sound-insulating- air chamber 34.
  • the plate 32 is turned and at that location abuts a ring surface 35 formed in the inside of the tube member 20.
  • a layer adhesive medium 36 is applied for attachment of the turned edge of the plate 32 .
  • the inner plate 33 is glued to the circumferential edge of the outer plate 32 turned at that location.
  • the plate 33 can be secured against a shoulder near ring surface 35 by means of an adhesive medium or by clamps.
  • the tube member 20 is double-walled, wherein the ring surface 35 via the shoulder connects to an inner wall 23, which continues to beyond the plane of the plate section 15 and defines a hollow chamber 24 with the outer wall 20a,b.
  • the outer wall 20b is also continued beyond the connection 38 on the plate section 15, in section 39b, ending in edge 25.
  • the outer wall 20a does not extend beyond the connection 27 to the plate section 15, yet runs more or less in the same plane with section 21, in order to run inwards at the location of folding line 22 in section 39a. It will be understood that the sections 39a,b smoothly connect to each other considered along the circumference of the tube member 20.
  • the hollow space 24 can be filled with a heat-insulating material and may optionally also provide sound-insulation.
  • the hollow chamber 24 is adjacent to or is functionally contiguous to the chamber 34 defined by the plates 32 and 33, so that no interruptions in the insulation worth mentioning are there.
  • the tube member 10 in the direction X slightly tapers with respect to the centre line S, having an angle Y of some degrees, for instance 2.5°. Characterising is that the centre line S of tube member 10 is at an acute angle ⁇ to the plane of the placement flange 4, of for instance 45° .
  • the inner wall 23 of the tube member 20 has a tapering corresponding to that of tube member 10, wherein the fit is such that sliding in the direction B is simple and sealing takes place by means of lip 11 a.
  • the outer wall 20a,b of tube member 20 tapers more than the inner wall 23 does, for instance at an angle ⁇ to the centre line S of approximately 5-10°, at an angle ⁇ of approximately 2.5-7.5°.
  • a light-emitting ring 37 is placed, which is further shown in figure 1 A and in detail in figure 1B.
  • the ring 37 is made of for instance PMMA, and has an outer edge 37a and an inner edge 37b.

  • the plate can be surface-treated invisibly at the outer surface, for instance printed or grooved, or be provided there with a finishing layer for breaking the LED light in the direction of the inner tube member. This treatment can be given in the form of a pattern or (comic strip/cartoon) figure.
  • the flange 30 now forms the upper edge of the tube member 20, with the plate assembly 31 situated within there, which assembly with plate 32 connects to the flange 30 in a water and airtight manner.
  • the skylight 1 of figure 1 is incorporated in a pitched roof 60 with tiles 61.
  • the flashing 40 is laid over the lowermost row of tiles 61.
  • the tube members 10, 20 extend horizontally from the roof. Due to the tapering shape of tube member 20 a to the eye horizontal direction is retained, within the usual roof slope range of 35-55°.
  • skylight 1 of figure 2 is shown in pitched roof 60. Due to the tapering shape of the tube member 20 a to the eye vertical alignment of tube member 20 is retained within a variation of roof slopes between 35-55°.
  • the skylight 1 offers an attractive, natural light and artificial light source for residential spaces below pitched roofs, wherein the reflecting layer 50 enhances passage of light.
