Definitions

  • the present invention relates to a mount for scissor-type guides.
  • Scissor-type guides are typically used to guide extension and retraction of lamellae for heavier types of blinds and armored blinds, and the like.
  • Scissor-type guides for guiding lamellae are used for e.g. heavier type of blinds, such as for use on the external side of a building structure, e.g. for regulating light, sound and/or air/gasses into/out of the building structure though openings therein.
  • opening may be windows or doors in a wall of the building structure, or overhead lighting openings.
  • façade elements e.g. build into frames on the façade.
  • a drive mechanism is used for moving the lamellae between a retracted position, and an extended position (and back). Further, the lamellae may be rotated between an open stat and a closed (shut) state.
  • the scissor-type guide of such blinds have one end, a first end, fixedly mounted to one edge of the opening, while an opposite end (second end) is freely moveable relative to the fixed, first end, of the scissor-type guide along a first direction, which is parallel to a plane defined by the opening in which the blind is arranged.
  • Scissor-type guides comprise a plurality of scissor links connected to each other along a first direction.
  • Each scissor-link comprises two elongate link members. The opposed ends of the link members of one scissor link, are connected - in rotational joints - to ends of the link members of two neighbouring scissor links along the first direction.
  • each scissor link may comprise a tilting arm configured for imparting rotation of the lamellae.
  • the rotation between two rotationally interconnected link members of a scissor link defines a plane.
  • the scissor-type guides are oriented in such a way that this plane is transverse to the plane of the building opening in which the blind is intended to be mounted. Thereby, the scissor-type guide will take up as little space as possible along sides of the opening. However other orientations are conceivable.
  • blinds or similar systems are hidden in the building structure surrounding the opening (wall, floor or roof). Even though this may hide the blind, it still takes up room that may otherwise have been used for enlarging the opening or for other technical equipment or insulation, etc. Therefore, there is a general need to make the blind, and in particular the scissor-type guide thereof, pack as compact as possible.
  • scissor-type guides are designed to fold/pack as compact as possible.
  • the primary focus of this effort has been on the main body of the scissor-type guides, i.e. the construction of the scissor links forming the scissor-type guide.
  • the guide mount, connecting the scissor-type guide to the edge of the building opening, typically via a bracket, a rail or the like, may take up space, both in the plane of the opening and in the transverse direction.
  • the extent in a direction transverse to the plane of the opening is defined by the length of the link members, and the angle at which they may be rotated relative to each other This angle may depend on a number of factors, such as the width of the individual link members, the type of rotational joints, etc. In any case, it is desirable that the mount, or first end connection, does not extend beyond the width of the scissor links (when the scissor-type guide is in retraced position), the width being defined by the plane defined by the rotation between link members, as described above. At the same type the first end of the scissor-type guide as such, i.e.
  • the scissor link closest to the mount should be brought as close as possible to the edge of the building opening (or the intermediary bracket or rail) to which the scissor-type guide is mounted, taking into consideration also parts (such as tilting arms) configured for rotating the lamellae.
  • German patent, DE 279 364 C discloses a tiltable tablet curtain, which are lowered and raised by means of Nuremberg scissors arranged on the front sides.
  • the scissors each have first and second scissor members connected in a rotational joint and with first and second mount members rotatably connectable to an opening of a building via first and second rotational joints.
  • Swiss patent, CH 468 542 A discloses a blind with tilting slats, and a scissor type guide.
  • French patent, FR 1 041 393 A discloses a scissor-type guide where the uppermost end of the uppermost scissor link are rotatably and slideably connected to a sliding bar, such that the scissor-type guide may be compactly retracted.
  • the sliding bar needs to extend beyond the width of the scissor-type guide in retracted position.
  • European patent application EP 2 540 951 A1 discloses a "Venetian” blind having a plurality of "slats" or lamellae whose left end portion cooperates with a lift mechanism, in the form of a scissor type guide, and a tilt mechanism. Independently driven tilt mechanisms at either side allows the lamellae to twist.
  • the uppermost scissor link is connected via two end link members, the uppermost end of which is joined in a single rotational joint.
  • the two end link members are equipped with elongate through going tracks allowing the two end link members to also slide relative to the rotational joint. This increases instability of the scissor-type guide at the end where it is mounted.
  • One or more objects of the invention may - in a first aspect or the invention - be achieved by a blind comprising a plurality of lamellae, a scissor-type guide for guiding the plurality of lamellae, and a mount for attaching a scissor-type guide to an opening of a building structure,
  • first and second rotational mount joints are arranged aligned on an axis being parallel to a third direction, which is perpendicular to the first direction.
  • the blind further comprises a frame, where, the first rotational mount joint of the mount is connectable to the frame, and wherein the second rotational mount joint is connectable to the frame.
  • the blind may alternatively or additionally comprise a first end bracket, wherein the first end bracket comprises the first and second rotational mount joints.
  • a length of the first mount member is half of a length of the first scissor member and a length of the second mount member is half of a length of the second scissor member.
  • the first mount member is non-slideably connectable to the opening of the building structure via the first rotational mount joint; and the second mount member is non-slideably connectable to the opening of a building structure via the second rotational mount joint.

  • the free, second end 22" of the scissor-type guide 20 is movable along the first direction D 1 .
  • the tilt system 110 comprising the tilt bracket 70 serves the purpose of aiding the tilting/rotation of the lamellae 30 between an open state and a closed state.
