Definitions

  • the present invention relates to daylight roller shutters as in accordance with the preamble of the main claim.
  • roller shutters when completely lowering the roller shutters either total darkening and when pulling up the roller shutters a glaring light point raster in the roller shutter itself and, in case of sun light incidence, in the interior space will occur. It is, therefore, that the prior art roller shutters are not suited as a sun protection measure in office buildings. Neither are total darkening nor light rasters on a working level acceptable. The light raster does not provide sufficient illumination of the interior space, particularly not in the room depth. With a view to its light and dark contrasts, the light raster has, however, a rather glaring effect. The prior art roller shutters do not permit a sufficient view-out.
  • This efficacy of LED-lighting is 70-80 Im/W while daylight behind a low-e-insulation glass brings 240 lm/W.
  • the light inciding from the outside on the roller shutters is not reflected to the inside but is substantially reflected back to the outside as a protection against overheating with the consequence of a strong darkening effect interior.
  • Solar gains in winter with lower angles of incidence can not be realised.
  • All prior art roller shutters comprise punched openings for light incidence into the interior space. Light guidance for an improved room illumination and the saving of energy for the electric illumination, however, is lacking. This refers also to JP 100 963 81 A and FR 2,941,989 which prevent any entry of direct radiation or mono-reflected radiation. FR 2,941,989 will guide at best diffuse light from the lower half space via double reflection into the interior space. Neither will a view-out nor room illumination by daylight result. The state-of-the-art does not offer any device to transport daylight into defined areas of the interior.
  • roller shutter which, while considering the angle of incidence of the sun, offers the possibility to determine the direct and the indirect light transmission, the direction of the transmitted light to the ceiling and into the room depth, the shadowing and the view-out within one curtain. It is the objective of the invention to adapt the roller shutter in its functionality additionally for the supply of daylight to interior rooms in order to save electric energy for the lamps and to minimize the internal heat loads as a consequence of electric lighting as well as to reduce the external heat loads in summer and at the same time guarantee a glare free work place. Further objectives are to realise solar gains only for low angles of incidence in winter by an angle selective aperture.
  • the decisive advantage is the adaptation of a roller shutter profile for daylight redirection by means of an integrated portion for light redirection into the upper half space of the interior room ceiling and/or into the room depth while not producing any glare on the work place.
  • the light reception bays are defined by light guiding surfaces having a flat inclination and are determined by the width b of the roller shutter profiles.
  • the protective function against too strong sun incidence (solar heat gain coefficient of the roller shutter) and the function of supplying daylight illumination are defined by the opening width W of the light guiding bay in relation to the height of the roller shutter profile (W/H).
  • the curtain may be adjusted, in accordance with a further development, more open in the upper window area, and for better shading of the window-near work place, optically more dense in the lower window area. Therefore, the curtain allows within its height a variable optical adaptability to the sun incidence and to the work place conditions by generating function zones wherein the upper part serves for improved daylighting and the lower part for the required shadowing.
  • a further advantage is that the adjustment of the daylight- and solar transmission is obtained by the orientation of a light guidance reflector.
  • An advanced type of shutter allows via up and down functions an additional daylight collecting and an improved visual transmission. If in case of a down function of the roller shutter the profiles pile up one upon the other, the angular inclination of the shadow line is adjusted at a base position ⁇ 2 ( Figs 1 , 5 ). If the roller shutter moves upward, the profiles suspend one in the other, a second, steeper-adjusted, shadow line at an angle ⁇ 1 will result ( Figs. 3 , 4 ).
  • roller shutter consists in that the individual roller shutter profiles in a down function pile up, first, in the lower area so that the window-near work place is well shadowed or even darkened ( Figs. 10, 12 ) while the roller shutter profiles in the upper area still suspend one within the other and hence open the view-out and light entry still more so that a good room depth illumination via the upper window area is obtained.
  • the directional room illumination, or the light distribution relative to the interior space is defined via a light guidance reflector having a width B.
  • the shape and the angle of inclination of the light guidance reflector may also vary within one curtain so that the sun light in the lower roller shutter portion may be deflected, glare-free steeply upward, onto the ceiling ( Fig. 9 ) and, in the upper roller shutter portion is deflected more flatly into the interior into the room depth ( Fig. 11 ).
  • the light guidance reflector is preferably shaped concave.
  • the essence of the invention is the integration of a light guidance reflector within the roller shutter profile.
  • the light- and energy transmission of the roller shutter is defined by the width and the shaping of the reflector as well as its inclination.
  • Essential of the invention is the shadowing of each upper profile to avoid over-illumination and overheating of the interior space relative to the high altitude of the sun in summer by the definition of the opening width W of the light guidance bay ( Fig. 15 ).
  • the light guidance bay is, therefore, defined as a hollow space similar to a loggia provided behind an outer line of the roller shutters.
  • the angle selective properties of the shutters are defined by the relation W/B and W/H.
  • the daylight roller shutter of the invention is characterized by a zoning into lower roller shutter areas and upper roller shutter areas, for instance above eye level.
  • the shadow lines S or the light and energy transmission values of the roller shutter between upper and lower roller shutter zones may freely be varied within one roller shutter.
  • the open and the closed portions of a roller shutter may freely be selected by up and down movement and in this way may glare-free be adapted to the sun incidence angle and the shadowing requirement at the window-near work place, on one hand, and the eye level of a person standing in the interior space and looking into the curtain, on the other.
  • the width B and the shaping of the light guidance reflector By the width B and the shaping of the light guidance reflector, the direction and the light distribution relative to the interior space are defined.
  • the opening width W in relation to the opaque retro-reflecting partial faces H By the opening width W in relation to the opaque retro-reflecting partial faces H, the quantitative light transmission, on one hand, and the protective function against overheating (total energy transmission) of the roller shutter, on the other, is defined.
  • the light bays are so shaped that the light guidance or the flat-disposed light redirection faces or mirrors can endure rain from the outside and are, therefore, self-cleaning as well. Rain impinging on the light guidance faces runs outwardly off dragging along any dust deposited.
  • Fig. 01 and Fig. 02 show a roller shutter profile from CH 345,145 A , where Fig. 01 shows the roller shutter in an open suspended state and Fig. 02 in a completely closed darkening state.
  • the reflected rays 203, 204 do not contribute to daylight illumination.
  • the embodiment of the invention of a roller shutter now provides that a daylight reflector of the kind of a light shelf be integrated in the profile so that the daylight may be reflected from the upper half space (upper window area) into the upper half space of the interior space (interior space ceiling and room depth) while no glare will occur at a work place.
  • Fig. 1 shows the vertical cross section of a façade-oriented room having a window-near work place, with the first function zone 10 in the upper window area and the second function zone 11 in the lower window area. It is the function of the upper window area 10 to reflect daylight 12, 13 into the room depth. It is the function of the lower window area 11 to primarily shadow the window-near work place 23 in that sun and heat are retro-reflected as shown by light beam 14 and 15. It is a further function of the upper light area to allow a view-out 16 from the room depth. In the lower window area, primarily a view-out 17 onto the street should be possible.
  • a shadow line 20 between two roller shutter profiles at a very flat angle ⁇ 1 should result in order to protect the window-near work place against direct high sun incidence.
  • the shadow line 22 may be provided steeper at an angle ⁇ 2 without producing a glare at the window-near work place.
  • different shadow zones 18, 19 will result which are regulated by sun incidence, on one side, and actively by the moving-down position of a roller shutter, on the other.
  • FIGs. 1 and 1.1 demonstrate the tasks and functions of a sun protection, taking into consideration
  • FIGs. 2 and 3 show the roller shutter profiles of the invention in their different positions to fulfil the tasks mentioned.
  • Fig. 2 demonstrates how the roller shutter profiles in the upper window area suspend one in the other. In the suspended position thereof, they show a defined view-out and a defined shadow line.
  • Fig. 3 shows the same roller shutter profiles as they are piled up one upon the other in the lower window area.
  • the figure shows a sun incidence 26 onto the roller shutter profiles at an angle ⁇ 2 .
  • ⁇ 2 is the angle inclination of the shadow line.
  • Sun incidence at an angle of incidence ⁇ ⁇ 2 may partly penetrate between the profiles into the interior space.
  • the portion 27 impinging on the light-deflecting upper side of the roller shutter profile of the invention is guided into the interior space as symbolized by the ray path 28.
  • a very good room illumination will, therefore, be obtained in the interior room depth via the upper window area.
  • excellent view-out 29 will be obtained between the roller shutter profiles.
  • either the complete roller shutter profile, or portion 34 only may be made reflective, for instance by applying a mirror.
  • the control of the curtain, the angular inclination of the shadow lines and, in particular, the size of the upper window area relative to the lower window light area, may very simply be executed by the mere up and down function of the curtain.
  • the stop point of the downward movement of the roller shutter may be programmed so that, by considering the sun incidence, the window-near work place is well shaded up to an angle of incidence > ⁇ 1 but is nevertheless well lighted by light reflection to the ceiling.
  • Fig. 2.1 shows the profiles suspended one into the other when guided in a lateral U profile.
  • the U-shaped guide shaft is schematically shown in the figure by the dotted lines 40, 41.
  • Fig. 2.2 shows the profiles in a typical original size. The smaller the roller shutter is made, the smaller is the roll-up diameter. It is even of advantage to shape the profiles in the width thereof ⁇ 5 mm.
  • the dotted areas 42 through 45 show the area of the punch-outs which may either be made as elongated slits or any optional hole images. In the case of residential houses, it might for instance recommendable to perforate the areas 42 through 45 with small holes only in order to assure at the same time protection against insects.
  • the individual roller shutter profiles consist of two portions, viz. a U-shaped hollow profile 46 with an angular reception 48 and a suspension angle 47.
  • the reception 48 and the suspension angle 47 lay themselves into one another and in this way arrest the roller shutter in its open function.
  • the suspension angle 47 lays itself in the base of U profile 46 and arrests the roller shutter in a closed position.
  • the characteristic feature of the present embodiment is that the roller shutter is never completely closed. By the moving of the individual roller shutter profiles into one another, it is only the light transmission behaviour which changes through the angle ⁇ of the shadow line.
  • the invention thus refers to a roller shutter having defined light-technological functions adaptable to work place situation and sun incidence. If the sun is higher than the shadow lines, the curtain may be rolled up further. In case of smaller sun incidence angles, in the morning or in the evening or in winter, the curtain may be moved into a closed position and thus will shade in case of more flat sun incidence angles as well.
  • the light incidence onto the light receiver or light redirective surfaces 56, 57, 58, 59 will change as well as is shown by way of example by rays 60 and 61.
  • the light receiver faces 56 through 59 serve as light reflector faces adding to the light gain in the interior space.
  • the upper side of the roller shutter profiles is made of stainless steel or aluminium with a glossy surface, a light reflection to the interior space will result as shown by ray 64.
  • the roller shutter profile for instance is dyed in white, diffuse light incidence will result as shown by ray bundle 65.
  • the present case deals with a daylight roller shutter the primary function of which should be seen in lighting design rather than in the black-out function of a classic roller shutter.
  • the light reception bay of the invention By means of the light reception bay of the invention, not only the direct light transmission between the profiles but also the indirect light irradiation is controlled which is caused by the light deflection on the roller shutter profile.
  • roller shutter area 51 an enforced indirect light influx of zenith radiation will occur while at the same time direct sun incidence of a light influx > ⁇ 2 is locked out. Because of the bay-shaped form of the light entry openings and the curvature of the partial faces for light reflection, the roller shutter executes differentiated functions relative to daylight modulation which serve for improved room illumination by diffuse daylight, on one hand, but also for simultaneous shading of the interior space, on the other.
  • Figs. 2.4 and 3.1 each show variants of profile shapes, in a drawn-up position in Fig. 2.4 and a moved-down position in Fig. 3.1.
  • the roller shutter profiles are characterized by the inverse hook-shaped connection of the roller shutter profiles with one another. By this turn of the hooks, different roll-up directions of the roller shutter will result, as can be taken from Figs. 4 and 5 . While in case of the profiles of Fig. 2 and Fig. 3 the roll-up shaft is disposed on the outside, the roll-up shaft in case of a profile shape of Fig. 2.4 and 3.1 is provided, according to Fig. 5 , on the inside.
  • roller shutter profiles 80, 81 for the upper roller shutter and roller shutter profiles 82, 83 for the uppermost roller shutter area below the lintel are shown.
  • the profiles 80, 81 and 82, 83 differ from one another by an elongated hook with a larger opening 84, 85. Thereby results a shadow line ⁇ 2 ' > ⁇ 2 and a view-out D 2 ' > D 2 and a larger light bay W 2 ' > W 2 .
  • the roller shutter profiles of Fig. 6 are moved together.
  • the following relations will result: ⁇ 1 ' > ⁇ 1 , D 1 ' > D 1 , W 1 ', > W 1 .
  • three function zones may be formed within one roller shutter.
  • Figs. 9 and 11 show a further variant of the innovation.
  • the light guiding portions 100 through 102 of Fig. 9 are positioned steeper, the light guiding portions 103 through 105 of Fig. 11 are positioned more flat. Thereby, different shadow lines will result at an angle ⁇ 1 in Fig. 9 and ⁇ 2 in Fig. 11 .
  • the view-out D in the horizontal direction of sight varies as well.
  • An embodiment according to Fig. 11 is arranged preferably in the upper window area, an embodiment according to Fig. 9 in the lower window area. In the upper window area, a flat light influx will result at an angle ⁇ 1 for an angle of incidence ⁇ 4 and in the lower window area, at a steep angle ⁇ 2 according to Fig. 9 .
  • the request is met to obtain in the lower window area a glare-free illumination with light deflection to the ceiling and in the upper window area room illumination in the room depth.
  • the shadow lines ⁇ 1 and ⁇ 2 vary as well.
  • the lower window area there is a very good view-out D to the street level so that with a view to the user, a homogeneous view-out in the interior view of a roller shutter will result.
  • roller shutter may be completely closed in the upper area ( Fig. 12 ) and in the lower area ( Fig. 10 ) and thus is also suited as a darkening for residential houses.

Based on such characteristic values, the lighting designer and the HVAC planner may determine, under consideration of the latitude of the construction site and of the orientation of the façades, the exact shape of the roller shutter profiles and decide on the passive cooling behaviour, on one hand, and the daylight illumination, on the other.
  • roller shutter profiles have, in the longitudinal direction, a kind of bore 110-115 ( Figs. 10 and 12 ) for receiving a front stopper which prevents reciprocal slipping of the profiles in their longitudinal direction.
  • roller shutter profiles shown are also to be seen in the elastic profile portions 120-125. These are rubber lips which when the roller shutter is being rolled up press against the base profile thus reducing the width b of the profiles.

  • the roller shutter is either produced from extruded aluminium or as extruded plastic profile or as a roll shaped profile of varnished steel or stainless steel or from a compound of various materials such as plastic material in combination with steel or stainless steel or aluminium.
  • the roller shutter profile 90 of Fig. 8 from highly transparent plastic material, for instance from acrylic or polycarbonate, where only the outer walls 91 and 92 irradiated by the high sun are provided with an opaque or coloured or a reflective material. This is performed by using a foil which is glued by means of a hot-melt glue onto the roller shutter profile or by using a transfer foil or by a hot embossing process for transferring a reflection layer onto the profile.
  • roller shutter profiles from a highly transparent plastic material are obvious.
  • the profile need not be punched, the view-out between the opaque portions is improved, the curtain is insulating relative to the heat absorbed at the outside of the roller shutter and moving upward.
  • the roller shutter will also serve as a protection against insects. If aeration of the roller shutter is desired, small holes might be punched into its transparent areas.
  • a further possibility is the co-extrusion wherein, in the extrusion process, metal strips are either applied or even implanted so that the metal strips are covered by the plastic material.
  • the outer sides 91 which serve as reflectors may for instance consist of stainless steel and the reflector 92 of highly reflective aluminium.
  • the individual faces may also be made in different colour variants.

  • steel strips may be inserted during the extrusion process.
  • roller shutter profiles from Figs. 9 and 11 and 18 are preferably produced by material combinations of poorer and better heat conductive materials, for instance of a hard and a softer plastic material or of a metallic material and a soft rubber.
  • the advantage of these compound materials is not only, as demonstrated, the flexibility of the profiles in their cross sectional dimensions but also the thermal separation to avoid heat conduction from the interior to the outside, or from the outside to the inside.
  • the roller shutter becomes a thermal insulator and will also serve to improve the heat transfer coefficient of the window.
  • Fig. 23 shows roller shutter profiles 300, 301, 302 formed like a parallelogram which in the combination of a plurality of profiles shows the typical innovative properties of light reflection 303 on the light reflecting upper side 304, 305, 306.
  • the shadow line 307 is defined by the distance between the roller shutter profiles which in the upper window area may be larger and in the lower window area may be selected smaller.
  • roller shutter profiles are spaced from one another by bands which in case of a complete downward run of the roller shutter fold together as can be taken from Fig. 24 .

  • polyester bars 310, 311, 312 are for instance built into the roller shutter profiles, which may for instance be connected by ultrasonic welding with a polyester band.
  • a gap may be provided in the roller shutter profile into which a press-in means or an inserting means is introduced which serves to fix the bands or cords.
  • a further embodiment of the invention provides that the roller shutter is bent prismatically above eye level, i.e. for instance at a level of 1.7 meter, roof-shaped, to the outside. In Fig. 25 , this is for instance performed by a servo motor 320 which pushes the roller shutter guide rails outwardly. At its lower point 321, the roller shutter is either held, as shown, in the façade face or, as drawn in dotted lines 323, is swung out as well.
  • the advantage is again seen in the daylighting, or the light technology, towards the interior space.
  • the roller shutter profiles in the upper window area provide, with a view to the changed positioning thereof, for a flat light redirection 330 via the daylight reflectors 331.
  • the light 332 is deflected more steeply to the ceiling.
  • the lateral roller shutter guide rail 333, 334 includes a hinge 335 into which a pressure crutch 336 of a servo motor 337 engages pushing the roller shutter to the outside.
  • Fig. 27 shows roller shutter bars 401 to 406 in the rolled down state with a shadow line of 20°.
  • the light reflecting faces 407 to 412 have a width B on the upper side of the bars and further light reflecting faces 413 to 418 on the underside of the bars.
  • Figs. 29.1 to 29.5 show the light reflective behaviour by raytracings between the profiles.
  • the reflectors facing each other form a reflector system forming a horizontal funnel.
  • the funnel is partly shaded by a small screen 440 to 445.
  • Fig. 29.1 shows the light reflection 420 and the direct light irradiation 421 for a sun irradiation angle of 10°. At a sun irradiation angle of 30°, the sun is reflected, in Fig. 29.2 , to the underside of the upper roller shutter bar.
  • Fig. 29.3 shows the light reflection from the underside of an upper profile back to the upper side of the lower profile as well as the back reflection 422 and 423 to the outside.
  • Fig. 29.4 and Fig. 29.5 show the analogue light reflection behaviour at a sun irradiation angle of 50°.
  • Fig. 28 shows the profiles of Fig. 27 in the pulled up state, which changes the shadow line to 35°.
  • the view-out D and D H horizontal
  • the light reflection behaviour between the profiles can be taken from Figs. 30.1 to 30.5 .
  • Figs. 30.1 to 30.5 In case of flat light irradiation of 10°, a larger portion of the winter sun will fall into the room. Even at an angle of incidence of 30°, the sun in Fig. 30.2 is almost completely redirected to the interior space ceiling.
  • an angle of incidence of 50° the sun in Figs. 30.4 and 30.5 is retro-reflected for the purpose of passive cooling to the outside by two reflections only.
  • the raytracings show the principle of function of the light reflection between two profile bars caused by a reflective surface without any light scattering losses. It is not, however, necessary to use smooth mirrors. So-called semi-spectral surfaces with a certain light scattering, anodized surfaces or also white or aluminium-coloured, glossy or dull surfaces are of advantage as well. All surfaces are suitable for the daylight roller shutter as long as light reflection/light scattering towards the interior will take place.
  • the individual profiles in the lowered state are kept via spacer blocks 450 to 454 at a minimum distance.
  • the individual roller shutter profiles are solidly connected via a band, not shown.
  • a distance d opens between the spacer blocks and the lower light reflective profile.
  • the spacer blocks may also be affixed to either the respective lower or the upper profile.
  • Fig. 27.1 shows the profiles of Fig. 27 , however without the spacer blocks in the closed darkening position.
  • Fig. 31 shows the suspension of a further roller shutter.
  • tube sockets 454 to 457 are inserted into which rotatable cylinders 458 to 462 are inserted.
  • At the front sides of the roller profiles are fixed at a spacer element.
  • a spacer element provides one longhole to enable the single profiles to be adjusted at two different distances to each other.
  • Fig. 32 shows the roller shutter bars of Fig. 31 with a central mounting support.
  • a spacer support with one longhole is shown in Fig. 32.1 .
  • tubes 470 to 472 are inserted which are positioned via spacers 473 to 476.
