Definitions

  • the present invention relates to a roof window shutter device for screening an opening, in particular the light-admitting area of a window mounted in an inclined roof surface, comprising a plurality of mutually articulated shutter plates, a drive mechanism for movement of the shutter plates between a storage position in a top casing, in which the shutter plates are stacked substantially in parallel with each other, and a screening position with the shutter plates positioned in front of the opening and in extension of each other, which screening position is defined by a pair of guide rails extending from the top casing and guiding opposing side portions of the shutter plates.
  • DE 29 47 501 discloses a roof window shutter device comprising a plurality of articulated shutter plates, and a drive mechanism for moving the shutter plates between a screening position where the shutter plates are positioned in front of the window and a storage position where the shutter plates are stacked in a top casing. In the storage position the shutter plates are stacked in a zig-zag pattern so that a front face of a shutter plate faces a front face of an adjacent shutter plate and a rear face of a shutter plate faces a rear face of an adjacent shutter plate, respectively.
  • a shutter device for screening a façade aperture such as garages and shop windows.
  • the shutter device comprises a top casing to be positioned inside the aperture so as to store shutter plates when not used to screen the aperture in a screening position.
  • the shutter plates are articulated by connecting members, which respectively are pivotally and slidably connected to adjacent shutter plates so as to allow the shutter plates to be stacked when moved by a drive mechanism from the screening position to a storage position inside the top casing.
  • a façade shutter with a similar principle is known from WO 03/ 060274.
  • WO 98/59144 and WO 98/27306 it is known to provide a shutter device for screening a façade aperture, wherein side portions of shutter plates are guided in tracks extending along the aperture and into a top casing for stacking the shutter plates.
  • the shutter plates are stacked in the top casing by means of a lift cable and a spring-loaded winder.
  • the present invention is characterized in that the top casing comprises opposing first guide tracks and opposing second guide tracks wherein first slide members and second slide members of the shutter plates are guided when the shutter plates are moved between the storage position and the screening position, that adjacent shutter plates are interconnected by connecting members with a first connecting portion pivotally connected and a second connecting portion slidably and pivotally connected to adjacent side portions of the adjacent shutter plates, and that the opposing side portions of the shutter plates are provided with a guide guiding the second connecting portion of the connecting members during movement of the shutter plates between the storage position and the screening position.
  • the guide tracks ensure that the shutter plates are guided to the intended position.
  • the flexible link between the shutter plates and the guide tracks makes it possible to guide the shutter plates to a storage position determined by the shape of the guide tracks, e.g. by tilting and elevating the shutter plates with respect to the screening plane without increasing the overall height of the top casing. Due to gravity forces a correct guidance of the shutter plates is especially important to ensure stable operation of the shutter plates of a roof window shutter device as the forces exerted on the shutter plates during movement between the screening position and the storage position or vice versa otherwise may result in tangled or stuck shutter plates.
  • the invention brings the advantage that stable operation of the shutter plates may be achieved even with relatively large shutter plates, i.e. the number of shutter plates may be reduced to for instance five or less. Hence less parts to assemble and less movable parts critical to obtain a stable operation.
  • connection members comprises the second slide members. This provides for an even more simple construction as to the number of parts and assembly, and a slide member may more easily be replaced.
  • the second slide members may be provided separately from the connection members, preferably connected to the shutter plates.
  • the second slide members and the first connecting portions of the connecting members are plane-parallel. This configuration has shown to be especially practical in order to provide a slim configuration of the top casing.
  • the opposing side portions define a length of the shutter plates extending between side portions extending in a width direction of the shutter plates, wherein the first slide members of the shutter plates are positioned between the guides and a side portion.
  • the guides of the side portions extend about 50 %, preferably about 75 %, and more preferably about 90 % of the length defined by the side portions.
  • the guide tracks in the top casing are adapted to angle the shutter plates with respect to the screening position when moved to the storage position.
  • the shutter plates When the shutter plates are positioned in the screening position they preferably abut, and ice on the abutting surfaces of the shutter plates may cause the shutter plates to get stuck together.
  • the shutter plates When the shutter plates are angled with respect to the screening plane when they are moved into the top casing towards the storage position, the ice may be broken and the shutter plates released from each other.
  • this is achieved when the first opposing guide tracks are provided with a bow so as to angle the shutter plates with respect to the screening position during movement of the shutter plates from the screening position to the storage position.
  • the side portions of the shutter plates are provided with toothed racks to engage with a pinion of the drive mechanism.
  • a tooth of the toothed rack is configured to allow the drive mechanism to engage between two adjacent shutter plates when one of the shutter plates is angled with respect to the screening position and the other is still in the screening position.
  • the shutter plates are stacked substantially in parallel with a screening plane defined by the shutter plates in the screening position.
  • the connecting members are positioned at an end of the guide facing towards a screening plane defined by the shutter plates in the screening position.
  • the pivot connection of the connecting member ensure that the shutter plates are lifted from the storage position when the shutter plates are moved from the storage position towards the screening position. This prevents the shutter plates from being stuck in the guide tracks when the shutter plates are lifted from the storage position to be guided to the screening position.
  • the shutter plates are stacked substantially perpendicular to a screening plane defined by the shutter plates in the screening position. This has shown to be especially advantageous when the slide pins extend from the side portion of the shutter plates.
  • the roof window shutter device comprising a lower shutter plate, which in the screening position is tilted with respect to the other shutter plates defining a screening plane. This provides for a better screening of the entire opening and the window in the screening position, and allows more light to enter the opening when the shutter plates are in the storage position.
  • the guide rails and the top casing when mounted on a roof window by means of a mounting bracket fixed in relation to the roof, are rotatable about an axis of rotation parallel with a screening plane defined by the shutter plates in the screening position.
  • the guide rails ensure a precise movement of the shutter plates to the screening position, and if the guide rails are mounted on a stationary window frame or the roof, a movable sash may, with the shutter plates in the screening position, be turned with respect to the frame so as to lift and rotate the guide rails and the top casing about the axis of rotation.

  • the guide rails 12 may be positioned a short distance from the top casing 8.
  • left-hand and “right-hand” refer to the orientation shown in for instance Fig. 1 and are utilized for reasons of convenience only.
  • the terms “upper” and “lower” refer to the orientation of an element with respect to the top casing, “upper” being a portion of an element intended to face towards the top casing, “lower” being a portion of an element intended to face away from the top casing in for instance in Fig. 2 .
  • the terms “front” and “rear” are utilized to denote the sides of the screening arrangement, “rear” being the side intended to face towards the roof of the building, and “front” the outwards facing side.

In the same manner the shutter plates 11 may be pulled from the storage position towards the aperture of the top casing 8 and thus eventually pushed towards the screening position.
  • the lower shutter plate 11a is angled with respect to the other shutter plates 11 and closes off the opening between the two guide rails 12. In the screening position one of the shutter plates is not fully released from the aperture 16 of the top casing 8 from which the guide rails 12 extend.
  • the aperture 16 is formed in a side wall 24 for abutting the upper member of the frame 4. Adjacent to the aperture 16 a drive mechanism 17 is provided inside the top casing 8.

  • Fig. 11 is a perspective view of the front surface 120 of a shutter plate 11 taken alone.
  • the upper lateral side portion 100 is provided with a tongue 70 and the lower lateral side portion 110 is provided with a groove 71.
  • the tongue 70 extending along the upper lateral side portion 100 is configured to engage with a grove 71 of a lower lateral side portion of a neighboring shutter plate 11 when positioned in the screening position.
  • Fig. 12 is a corresponding perspective view of the rear surface 130 of a shutter plate 11 taken from another angle showing in more detail the groove 71 extending along the lower lateral side portion 110.
  • On each side of the tongue 70 a resilient sealing element 72, 73 extending along the upper 100 and lower 110 lateral side portions is provided. The sealing element 72, 73 ensure that in the screening position when the tongue 70 is guided into the groove 71, the transition between the two shutter plates is sealed to avoid penetration of water between the shutter plates 11.
  • Fig. 13 is a partly perspective cross sectional view along the line XIII in Fig. 2 .
  • the sealing elements 71, 72 positioned on the upper lateral side portion 100 and constitute a gasket 23.
  • the gasket 23 is preferably made of a rubberlike flexible material, which may be deformed when the shutter plates are moved towards each other.
  • the sealing elements 72, 73 are configured as part circular rubber walls, which are depressed when the tongue 70 is guided into the groove 71 so that the sealing elements 72, 73 fills out and seal the transition between abutting lateral side sections of the shutter plates 11 when positioned in the screening position. I.e. the situation depicted in Fig.
  • FIG. 13 illustrates the sealing elements 72, 73 in a position just before the sealing elements 72, 73 are depressed and the shutter plates are positioned in the screening position. Furthermore, the gaskets 23 ensure that when the shutter plates are pressed together light will not enter between the shutter plates 11.
  • the connecting engagement between an upper 100 and a lower 110 lateral side section of adjacent abutting shutter plates also improve the screening properties, but also makes the roof window shutter device 1 more robust in the screening position where e.g. snow may aggregate on the front surface 120 of the shutter plates.
  • the connecting members 29 and their connection to the side portions 15 of the shutter plates are configured so that when the shutter plates are moved from the fully screening position as shown in Fig. 2 towards the storage position, an elongate light-admitting aperture 80 is provided between the shutter plates 11 along the upper and lower lateral side sections 100, 110 of adjacent shutter plates 11.
  • Fig. 14 shows the connection between two adjacent shutter plates in a situation where the shutter plates are guided by the guide rails 12 towards the storage position.
  • the right-hand side of the connecting member 29 is pivotally connected to the side portion 15 close to the lower lateral side portion 110 of a shutter plate.
  • the left-hand side of the connecting member 29 is slidably connected to the guide 30 of another neighboring shutter plate and has moved to an end of the groove situated close to the upper lateral side portion of the shutter plate 11.
  • the connecting member 29 and the connection of the connecting member 29 to the shutter plates are configured so that an elongate light-admitting aperture 80 is provided between the shutter plates when moved towards the storage position. Besides from providing a light-admitting position wherein the major part of the opening is still screened, this configuration of the connection between the shutter plates allows the shutter plates 11 to be turned and moved during stacking as described above.
  • Fig. 15 shows the left-hand side guide rail 12 of Fig. 2 in a perspective view.
  • the guide rails 12 are preferably manufactured by extrusion and comprises mounting holes 91 e.g. for a screw for mounting the bottom pieces 14, which serve as end stops for the shutter plates when guided to the screening position.
  • the guide rail 12 comprises a guide track 90 with a slide surface 92 on which the side portions 15 of the shutter plates 11 slide when moved along the guide rails.
  • the guide track 90 of the guide rail is in communication with the aperture 16 of the top casing so that the shutter plates are securely guided when moved outside the top casing 8.
  • the guide rails 12 comprises two tracks in respective communication with the guide tracks 19, 20 of the top casing 8.
  • the slide pins 27, 28 of the side portions 15 of the shutter plates may be positioned towards the front surface 120 and the rear surface 110, respectively, so as to be guided in different parallel tracks in the guide rails 12.
  • the first guide track 20 in each side of the top casing extends into a corresponding upper track of the guide rails 12, and the second guide track 19 in each side of the top casing 8 extends into a corresponding lower track of the side rails 12.
  • the guide rail 12 comprises a mounting rail 93 for mounting on the side members of the frame 2.
  • FIG. 16 and 17 another detail of an embodiment of the invention is shown in more detail, namely the different levels of the first slide member 27 and the second slide member 28 relative to the thickness or height direction of the shutter plate.
  • the slide members 27, 28 of the shutter plates are positioned in different planes, such that the slide pin 27 is located close to the front surface 120 and the slide pin 28 near the rear side surface 130 of the shutter plates, respectively. This is illustrated by letters a and b, respectively.
  • the different levels allow the two slide members 27, 28 to enter safely into the two different tracks 20 (of which the first portion 32 is shown in these Figures) and 19, respectively, when the shutter plates enter the top casing. It is noted that the cross-sections of the slide members 27, 28 do not overlap.
  • the tracks could continue along the guide rails also, which increases the secure engagement with the respective track even further.
  • there is only one track in the guide rails and the shutter plates are guided on the bottom of the side portions of the shutter plates, corresponding to letter c in Figs 16 and 17 . Forming the guide rails with two tracks as well is of course conceivable.
