Definitions

  • the invention relates to a slatted blind according to the preamble of claim 1.
  • the slatted blind is a blind with movable slats for sun and weather protection as well as privacy and, if necessary, security.
  • the slatted blind is also referred to as the Raffstore or the slatted blind.
  • Slatted blinds with side guides, slats and an end rail are used to close and open building openings such as windows and doors.
  • the end rail is lowered and raised using lifting straps, for example.
  • the inclination of the slats is adjusted using adjusting cords, for example, whereby the adjusting cords are attached to the edges of the slats on both sides of the longitudinal axis of the slats.
  • Slatted blinds enable the complete opening, covering of an upper area and the complete covering of building openings by positioning the end rail arranged under the slats accordingly.
  • the inclination of the slats can be adjusted to a horizontal level.
  • the same drive device is used for adjusting the slat inclination.
  • EP 1 213 437 A2 describes slatted blinds that can expose an upper area of the building opening while covering the remaining lower area.
  • a slatted blind comprises a top rail, slats, an end rail, two guides and two drive devices arranged on the guides for moving the top rail or the end rail and for adjusting the inclination of the top rail.
  • the guides and the drive devices When installed, the guides and the drive devices extend over a height range at the opposite longitudinal ends of the top rail and the end rail.
  • the drive devices comprise closed chains with two support elements each running around an upper and a lower deflection device.
  • the support elements make two top rail brackets with the top rail arranged therebetween displaceable between an upper and a lower top rail end position or end rail brackets with the end rail arranged therebetween displaceable between an upper and a lower end rail end position along the guides, wherein the end rail is at the lower end rail end position when the top rail is moved and the top rail is at the upper top rail end position when the end rail is moved.
  • the solution according to EP 1 213 437 A2 The inclination of the slats that are not stacked on the end rail can be adjusted by adjusting the inclination of the top rail. To do this, adjusting cords on both sides of the longitudinal axis of the top rail lead from the top rail edges to the corresponding slat edges that are attached to the adjusting cords at equal intervals.
  • the solution according to EP 1 213 437 A2 The inclination of the slats cannot be set to any desired angle.
  • an inclination of around 45° to the horizontal plane is specified so that the slats can be placed without interference on the end rail positioned at the lower end rail end position or on the slats lying on it when lowered.
  • the top rail moves upwards, the slats are in the open position with an inclination of around 0°.
  • the object of the invention is to find a solution in which the slats above the stack on the end rail can be adjusted between an open orientation that deviates only slightly from the horizontal orientation and a substantially vertical or closed orientation when the top rail is positioned below the upper top rail end position.
  • the upper rail brackets which hold the upper rail and move it along the guides, must enable a change in function from the movement of the upper rail to the adjustment of the inclination of the upper rail or vice versa at any position between an upper and a lower upper rail end position.
  • a reversal of the direction of movement of the Drive devices or their supporting elements that support the top rail brackets do not move the top rail along the guides in the opposite direction, but rather the inclination of the top rail is adjusted.
  • the top rail should only be moved after the inclination of the top rail has been adjusted to a predetermined closed or open state.
  • the change in function when changing the direction of movement of the support elements can be achieved if the upper rail holders comprise inclination adjustment devices with clamping devices.
  • the clamping devices can be clamped to the guides to adjust the inclination of the upper rail and can be moved along the guides to move the upper rail.
  • the two states “clampable” and “movable” are achieved with a device that can apply and release a braking force or a holding force between the upper rail holders and the guides.
  • the clamping devices can be designed as braking devices or, if necessary, as latching devices and the clamping thus comprises frictional contacts and engagement contacts.
  • the end of the adjustment of the inclination is signalled by a movement of the supporting elements according to a predetermined
  • the adjustment of the clamping devices and the associated release of the clamping on the guides are achieved by the movement distance. After the clamping is released, the further movement of the support elements causes a movement of the top rail brackets and thus of the top rail along the guides.
  • both top rail holders comprise guide parts that are slidably guided on the guides and on which the clamping devices of the inclination adjustment devices are arranged so that they can move between two end positions.
  • the support elements move the guide parts along the guides and the clamping devices that are movably arranged on the guide parts cannot be moved along with them, but remain at the clamping points on the guides.
  • the clamping devices remain in the positions of the guides determined by the clamping until the guide elements are moved relative to the clamped clamping devices to such an extent that the further movement of the guide elements results in an adjustment of the clamping devices.
  • This adjustment causes the clamping on the guides to be released and a movement the guide parts together with the clamping devices along the guides.
  • the clamping devices are designed in such a way that the described function change can be achieved for both directions of movement of the top rail brackets and for both pivoting directions of the inclination adjustment.
  • the clamping and the displaceability of the clamping devices on the guides depends on the position of the clamping devices relative to the guide parts. If the clamping devices are positioned in a range between two end positions on the guide parts that limit the range of relative movement, the clamping is set and if the clamping devices are positioned at one of the two end positions on the guide parts, the displaceability is set.
  • the clamping devices each comprise a base plate on the guide part that can be moved in the direction of the associated guide and two movable clamping elements on the base plate.
  • the two movable clamping elements are pre-tensioned to clamp onto the associated guide for one of the two directions of movement of the guide.
  • the clamping elements can be used as braking elements or, if necessary, are designed as snap-in elements and the clamping thus includes friction contacts or engagement contacts with the associated guide.
  • the movable clamping elements can be adjusted against the preload by a release device on the guide part to release the clamping.
  • the base plate with the guide part can be moved by the support element along the guide.

With this adjustability, the inclination of the top rail can be set as desired from completely open to completely closed. As soon as the desired inclination is reached when adjusting the inclination, the movements of the support elements and the guide parts moved with them are stopped.
  • the coupling transfers the relative movement between the guide parts and the base plates guided on them into a movement of the inclination adjusters.
  • the coupling on the clamping devices in particular on the base plate, comprises curved guides and the inclination adjusters can be rotated about an axis of rotation running parallel to the longitudinal axis of the top rail.
  • the couplings also comprise swivel arms that are firmly connected to the inclination adjusters and are guided on the curved guide with a guide engagement spaced from the axis of rotation.
  • the relative movement between the guide parts and the base plates guided on them leads to a movement of the guide engagements along the curved guides.

This predetermined inclination of the top rail corresponds to a desired working position of the slats when the end rail moves.
  • the holding arms are provided with anti-release devices which prevent the support elements from coming out of the holders when the upper rail is lifted manually.
  • the devices include, for example, safety plates which only allow the support elements to be removed from the holders when the upper deflection device is used.
