Definitions

  • the present invention relates to a device for building facades for controlling the incidence of light, with surface elements which can be pivoted about horizontal axes and which can be moved between a shade-providing position and a light-entering position.
  • this object is achieved in a device of the type mentioned in that the surface elements are articulated to one another via a pivot axis and can be pivoted together in opposite directions.
  • the surface elements can thus be folded together and apart from one another in the manner of a fan fold around the likewise horizontal pivot axis. With a change in the angle of attack of the surface elements, the effective surface of the surface elements projected onto the facade is changed at the same time. This results in efficient control of the incidence of light in the interior of the building.
  • a surface element is pivotally mounted about a fixed axis and the surface element articulated thereon is displaceable along a guide.
  • the pivoting of the one surface element causes the surface element articulated thereon to move along the guide and vice versa.
  • the guide is preferably designed as a backdrop in which the articulated surface element is guided.
  • the guide expediently extends essentially parallel to the facade, ie generally vertically, when the device is attached to vertical building facades. If, on the other hand, the device is intended for inclined building surfaces, in particular for inclined skylights and the like, then the guide is also oriented in a correspondingly inclined manner.
  • the common pivot axis connecting the articulated surface elements can be moved freely by the guide.
  • the instantaneous center of rotation of the articulated surface element lies on the intersection of a straight line perpendicular to the guide and a straight line connecting the fixed axis and the common pivot axis.
  • the fixed axis of one surface element and the guide for the surface element articulated thereon lie approximately in one plane.
  • the fixed axis and the guide are approximately the same distance from the building facade, preferably at least about a third to half the height of a surface element transverse to the pivot axis.
  • the surface elements have enough space to swivel together without hitting the building facade.
  • the fixed pivot axis of the one surface element and the guidance of the surface element articulated thereon can coincide with the horizontal edge of the respective surface element, the opposite edges of the surface elements being articulated to one another.
  • the fixed pivot axis of the one surface element and the guidance of the surface element articulated thereon preferably lie between the corresponding horizontal edges of the surface elements.
  • the fixed axis and the articulation point for the link guide are arranged approximately in the middle between the horizontal edges of the surface elements.
  • the distance of the fixed axis from the common pivot axis connecting the surface elements is approximately one third to half the height of the surface element, which is measured transversely to its horizontal edges.
  • the distance of the articulation points for the link guide from the common pivot axis connecting the surface elements can in particular be approximately half to two thirds of the height of the articulated surface element.
  • the surface elements are expediently arranged on the outside of the building facade in order not to take up any space from the rooms inside the building and to ensure free access to the windows or doors.
  • the distance from the building facade in the pivoted apart, ie shading position can be selected differently. It is preferably approximately two fifths of the room height of the room to be shaded, to which the surface elements are assigned.
  • At least one of the surface elements on one side is advantageously designed to be light reflecting, in particular mirrored, and can be pivoted into a position in the side reflecting from the light Daylight is directed into the interior of the building.
  • the surface elements can be pivoted in such a way that the light-reflecting side is correspondingly pivoted away in the shadow-providing position. All surface elements on one side are preferably designed to be light reflecting.
  • the surface elements are curved, in particular in the light-introducing position they are concave towards daylight.
  • the curvature is expediently provided only in one direction, in particular transversely to the horizontal edge of the surface element. Horizontal sections through the surface elements are therefore straight lines.
  • the individual surface elements are curved in such a way that they are curved in the same direction when pivoting towards one another in order to fit at least roughly like a spoon.
  • the surface elements articulated to one another When unfolded, i.e. in the shadow-giving essentially vertical position, the surface elements articulated to one another have an essentially S-shaped cross section.
  • the surface elements In order to improve the sense of space, the surface elements also allow the view outside, or at least to a limited extent, the entry of light from outside, even in their shady position. A line of sight from the interior of the room to the outside is maintained.
  • at least one, preferably each surface element can have light passage openings. These can be designed as perforations or as small holes.
  • the surface elements preferably have horizontal slots. In the shade position, when the surface elements are pivoted apart, they can cover about three quarters of the floor height. In the case of windows that run from floor to ceiling, the lower part remains free to provide a line of sight to the building surroundings.
  • the device has two surface elements which are articulated to one another.
  • each of the surface elements can be of multi-part or multi-part design, in particular the surface elements can have vertically extending subdivisions.
  • the surface element has a uniform structure that can be pivoted as a unit.
  • the surface elements each have half surfaces arranged offset from one another.
  • the term "half" does not mean that the entire surface of a surface element is divided into two halves of equal size.
  • the half-faces can be of different sizes. More than two surface pieces can also be provided.
  • the half-surfaces are preferably arranged such that they overlap one another and leave a slot-like or gap-shaped opening in the overlap region and continue the contour of the other surface piece in a step-like manner.
  • lateral support ribs can be provided, to which the surface pieces are attached.
  • the pivot axes and also the articulation points for the guide of the articulated surface element can be attached to these support ribs.

  • the device has an upper surface element 1 and a lower surface element 2, which are connected to one another via a pivot axis 3.
  • the pivot axis 3 connects the surface elements 1 and 2 at edges that extend horizontally, i.e. the pivot axis 3 also extends in the horizontal direction.
  • a hinge or other pivotable or bendable connecting means can be provided as the pivot axis.
  • the upper surface element 1 is rotatably mounted about a fixed, also horizontally extending axis 4 (cf. FIG. 5).
  • a carrier 5 is provided which carries the surface elements and in particular the fixed axis 4.
  • the carrier 5, which consists essentially of two vertically extending profiles arranged on both sides of the surface elements 1 and 2, can expediently be firmly anchored in the building facade.
  • the fixed axis 4, as shown in FIG. 5, is arranged in a central region of the upper surface element between its horizontal edges, in particular the fixed axis 4 lies approximately one third to half the height of the upper surface element 1 from its edge, at which the lower one Surface element 2 is articulated, removed.
  • the height of the surface element means the distance between the two horizontal edges of the surface element.
  • the lower surface element 2 is guided on both sides in a guide link 6, which extends vertically and is also held by the carrier 5.
  • the guide link 6 is arranged such that the fixed axis 4 would lie approximately on an extension of the guide link, i.e. the guide link and the fixed axis are roughly the same distance from the building facade.
  • the lower surface element 2 is guided in a central region between its horizontal edges in the guide link 6.
  • the articulation points of the lower surface element 2 on the guide link 6 lie approximately two thirds of the height of the surface element from the edge at which the surface element is articulated on the upper surface element 1.
  • the distance between the two horizontal edges of the lower surface element 2 is again referred to as height.
  • Both the upper and the lower surface element 1 or 2 each have laterally arranged profile or support ribs 7 which are connected to one another by half surfaces or surface pieces 8 fastened thereon (cf. FIG. 5).
  • the surface pieces 8 can be designed, for example, as sheet metal sheets, wooden panels or plastic panels.
  • each of the surface elements 1 and 2 has two separate surface pieces 8 arranged offset from one another, which overlap one another in the direction transverse to the horizontal edges and delimit a gap 9 between them in the overlap region.
  • the step-like displacement of the two surface pieces 8 is roughly speaking in the middle part of the respective surface element (cf. FIG. 5).
  • the lower surface element 2 has in the region near its upper edge, ie near the edge to which the upper surface element 1 is articulated, a plurality of slit-shaped light passage openings 10, which are separated from one another by longitudinally extending, strip-shaped lamellae 11.
  • the strip-shaped lamellae are oriented such that they lie essentially horizontally when the lower surface element 2 is pivoted into its light-admitting position (cf. the dashed position of the lower surface element in FIG. 5).
  • Both surface elements 1 and 2 are concavely curved, the curvature being designed such that horizontal cuts through the surface elements 1 and 2 result in straight lines.
  • Concave means that the surface elements 1 and 2 in their open position (see the dashed position in FIG. 5) are concavely curved towards the direction of incidence of daylight. In this case, both surface pieces 8 are curved accordingly for each surface element. If the surface elements are closed, i.e. are pivoted apart in a substantially vertical manner, the curvature of the two surface elements is opposite in cross-section, i.e. S-shaped.
  • the surface elements 1 and 2 are significantly larger. As shown in FIG. 2, about three quarters of the floor height can be dimmed with two surface elements. The height of a surface element between its two horizontal edges is on the order of approximately one meter.
  • the perpendicular profiles of the support 5 extend at a sufficient distance from the building facade to allow the surface elements 1 and 2 to be pivoted together.
  • the distance from the building facade is dimensioned such that the surface elements do not abut the building facade in an approximately horizontal position.
  • the surface elements 1 and 2 are pivoted apart, so that they are oriented essentially vertically and their effective surface projected onto the building facade is at a maximum.
  • the upper surface element 1 is pivoted downward with the section to which the lower surface element 2 is articulated, so that the lower surface element 2 moves downward in the guide link 6 and the position shown in solid lines in FIGS. 1 and 2 occupies.
  • the surface elements cover about three quarters of the continuously glazed outer wall of a floor and leave only the remaining, lower section of the outer wall uncovered. It should be noted that due to the curvature of the surface elements 1 and 2, the upper edge of the upper surface element is closer to the building facade than the lower edge of the lower surface element 2 (see FIG. 2), so that the sunlight that regularly falls from above does not can get directly into the interior of the building. On the other hand, the curved design allows a larger field of view through the lower, uncovered section of the glass facade, since the lower edge of the lower surface element 2 lies relatively far in front of the building facade.
  • the slot-shaped light passage openings 10 still maintain a line of sight from the interior of the room to the outside even in the shade position. Daylight can also enter the interior of the building.
  • the surface elements act effectively as protection against direct solar radiation, which significantly reduces the total energy transmission and prevents excessive heating in summer.
  • the lower surface element 2 By pivoting the upper surface element 1, which can be done electrically, for example, by means of a pivoting device (not shown in more detail), into a substantially horizontal position (cf. FIG. 4, there the position in the solid state) Line), the lower surface element 2 is pulled upwards, whereby it also rotates into a more horizontal position.
  • the rotation of the lower surface element 2 is effected in that the pivot axis 3, with which the lower surface element 2 is articulated on the upper surface element 1, is moved closer to the building facade.
  • the lower surface element 2 slides upward in the guide link 1 and rotates into said more horizontally oriented position.
  • the lower surface element in the guide link 6 could also be pulled up or pushed, so that the upper surface element 1 would forcibly be pivoted and the corresponding light-admitting position would be obtained.
  • the lower surface element 2 gives the field of vision to the outside environment for standing people inside the building almost without restriction (see FIG. 4), since the lower surface element 2 was not only moved upwards, but was also pivoted.
  • the effective surface of the two surface elements 1 and 2 projected onto the building facade is substantially reduced in the swiveled-together position, so that daylight can enter the interior of the building almost unhindered.
  • the concave side of the upper surface element 1 is designed to be reflective, in particular mirrored, and accordingly to direct the daylight into the interior, including the zenith light that is present even when the sky is cloudy.
  • the curvature or the orientation of the upper surface element 1 is coordinated such that the daylight is thrown onto the ceiling by the reflection on the mirrored side of the upper surface element 1. This achieves advantageous illumination of the room, comparable to skylight, down to the depth of the room.
