Definitions
- the invention relates to a slatted blind with a curtain made of several horizontal slats, which are arranged on turning and holding members spaced are,
- the invention further relates to a slat, in particular a slat for slatted blinds.
- Such slatted blinds or slats of this type are made of, for example DE 44 42 870 or EP 0 793 761, in which the sunlight facing the top of the slats a light reflecting surface has.
- a outer lamella section adjacent to the solar radiation is a step-shaped one Cross-sectional profile.
- the outer lamella section goes under formation a first raised, longitudinally extending bending edge in an inner lamella section facing the interior to be shaded above, which is concavely curved upwards in cross section.
- the object of the invention is therefore a slatted blind of the type mentioned kind of further training in such a way that - with an overall simple structure - direct sunlight through the curtain of the slat is effective is reduced.
- the advantages of the invention are in particular that several or all Slats that form a curtain section or the entire curtain for Side of the solar radiation with a stripe-shaped, in the longitudinal direction of the lamellar retroreflective layer or coating are provided.
- This retroreflective layer or coating has the Ability to reflect incident light rays in the same direction with that comes in the light. So while reflecting on reflective surfaces according to the law of reflection between the incident light beam and the angle of incidence formed equal to that between the surface normal and reflected beam is the measured angle of reflection, is at retroreflective layers the incident light back to the light source, i.e. reflected back in the direction of incidence. That on the retroreflective Sunlight striking the layer is thus reflected back to the sun.
- the Penetration of direct sunlight which with a comparatively large This prevents the angle of incidence from striking the slats of the curtain. Only what is incident at a small angle of incidence can pass through the curtain diffuse light, which produces no glare.
- the strip-shaped section with a retroreflective Layer or coating is provided over the entire length of the slats or a group of slats, and the stripe width b of the retroreflective Layer is smaller than the lamella width B.
- the stripe width b of the retroreflective layer is preferably dimensioned so that the incident Sunlight from a given desired angle of incidence - at given curtain data - completely on retroreflective surfaces of the Slats strikes because with this dimensioning a reflective reflection of the Sunlight prevented on the non-retroreflective sections of the slats becomes.
- the strip-shaped retroreflective is therefore preferably located Layer in the area of the sunny side, i.e.
- outer slat longitudinal edge and extends across the strip width across this longitudinal edge b - for example up to about the middle of the lamella cross section.
- outer longitudinal edge of the retroreflective falls Layer together with the outer longitudinal slat edge.
- the retroreflective layer can either be applied directly to the slats Apply the form of a suitable material coating. Alternatively, the retroreflective layer, however, applied to a carrier layer in turn is attached to the slat.
- the slats have a cross-sectional profile, which is flat or in cross-section is curved, the outer layer covered with retroreflective layer i.e. the section on the sunny side and the section on the inside inner lamella section by a longitudinally extending bending edge can be separated and different curvatures in cross section can have.
- Fig. 1 shows a cross section through part of a curtain of a Venetian blind.
- the curtain 1 has a plurality of turning and supporting members 2, which in the embodiment shown consists of two cords 4, 6, which in predetermined distance from each other with thread or cord-like crosspieces 8 are connected.
- slats 20 On the crossbars from horizontally spaced Turning and holding members 2 lie on slats 20, which are from the turning and Holding organs 2 worn and when adjusting the cords 4, 6 also their inclination can be adjusted.
- Traction elements 10 which are attached to a lower end plate (not shown) are and in the head profile of the slatted blind by means of suitable electrical or mechanical drives can be wound up and unwound.
- the slats 20 have an outer longitudinal edge lying on the sunny side 22 and an inner longitudinal edge 24, which is to be shaded Interior is directed.
- the Slats facing the sunny side one running in the longitudinal direction strip-shaped section with a retroreflective layer or Coating 30 is provided.
- the stripe-shaped retroreflective layer 30 extends in the longitudinal direction over the entire length of the lamella, cf. Fig. 2b and has a width b that is less than the total width B of the slat 20 is.
- the outer longitudinal edge falls the layer 30 together with the outer longitudinal edge 22 of the lamella, and layer 30 ends approximately in the middle of lamella 20.
- the cross section of the lamella according to FIG. 3 is curved in different ways.
- the slat 20 has - starting from the outer longitudinal edge 22 - an outer Lamella section 27, which extends to a lengthwise Bending edge 26 extends and provided with a retroreflective layer 30 is.
- An inner lamella section 28 runs from the bending edge 26 to to the inner longitudinal edge 24 and has a - in cross-section - concave upwards open curvature leading to the inner longitudinal edge 24 in an upwardly convex Curvature passes.
- the inner lamella section 28 preferably has a reflective surface, so that the - diffuse - sunlight hitting there can be deliberately reflected upwards into the interior:
