Definitions

  • the present application relates to a folded ceiling baffle, in particular constructed from a sheet of felt having respective portions of shape and size that may be folded to form the ceiling baffle.
  • baffles It is known to suspend from a ceiling structure a plurality of baffles. These are elongate panels which are generally larger in height than in width. It is also known to construct such ceiling baffles from a felt material, for example as described in US 2018/0127975 .
  • the protrusion received in the space resists the first and second end parts unfolding about the first and second side edges respectively.
  • the first and second end parts unfold about their respective first and second side edges, then they unfold outwardly from the ceiling baffle and the form of the one end of the baffle is no longer planar.
  • Use of the protrusion and space is effective in resisting the unfolding of the first and second end parts so that the first and second end parts are retained together forming the planar end portion.
  • the opposite end of the baffle may similarly be provided with end parts folded from the elongate sides and meeting together to form a planar opposite end portion. These end parts may similarly be provided with a protrusion and space respectively for retaining the end parts together as the planar opposite end portion.
  • the folded ceiling baffle may further include a first inner flap extending from the first inner edge inwardly of the ceiling baffle, for instance into the interior space of the baffle, and a second inner flap extending from the second edge inwardly of the ceiling baffle.
  • the first inner flap includes a first planar surface and the second inner flap includes a second planar surface.
  • the first planar surface extends from the first inner edge and extends on the same side of the sheet as the outer surface of the first end part and the second planar surface extends from the second inner edge and extends on the same side of the sheet as the outer surface of the second end part.
  • the first and second inner flaps may face each other such that, similarly, the first and second planar surfaces face each other.
  • the first and second inner flaps may flex/fold outwardly towards a coplanar state with the respective first and second inner flaps.
  • the first and second planar surfaces may be brought into contact with each other.
  • the first and second planar surfaces resist movement relative to one another.
  • the relative states of the first and second end parts are move effectively maintained such that the planar state of the end portion is more effectively maintained.
  • felt having a thickness of between about 3 mm and 10 mm, preferably between about 4.5 mm and 7.5 mm, and more preferably between about 5 mm and 6.5 mm.
  • a thickness of 5 mm or 6.5 mm might be chosen with a tolerance of about 10%.
  • the protrusion of the first end part may be a cut-out from the first inner flap.
  • cuts may be made through the thickness of the sheet in the area of the first inner flap. In particular, these cuts may extend from the first inner edge. In this way when the first inner flap is folded from the first end part, the protrusion, remaining coplanar with the first end part, lifts out of the first inner flap as a cut-out from the first inner flap.
  • the protrusion may be narrower at the first inner edge than at at least one portion distal from the first inner edge.
  • the protrusion cannot be withdrawn from the space by relative movement of the first end part away from the second end part in the plane of the planar end portion.
  • the relative positions of the first end part and the second end part in that plane are therefore securely maintained.
  • the relative positions of the first end part with the second inner edge of the second end part are securely maintained and cannot be separated.
  • This arrangement is particularly effective in conjunction with first and second planar surfaces which contact and engage with each other. The interaction of the protrusion and the space prevent separation of the first and second planar surfaces from one another so that the state of the first and second end parts together forming the planar end portion is maintained effectively.
  • the protrusion may have sides which are angled away from each other.
  • the protrusion may have a dovetail shape.
  • the protrusion and the space may have complimentary dimensions.
  • the protrusion and the space may fit together in a manner to resist relative movement.

  • the resulting formed planar end portion has no gaps or holes.
  • the space may be considered as being defined by the edges around it.
  • these edges may be described as surrounding edges.
  • the protrusion may resiliently engage with the surrounding edges and be held frictionally within the space. Such an arrangement may resist the protrusion leaving the through-hole in a direction away from the plane of the second end part.
  • the space may extend through the entire thickness of the second end part and, hence, take the form of a through-hole.
  • the surrounding edges may extend only partly through the thickness of the second part so that the space takes the form of a recess in the outer surface of the second end part.
  • the space may be formed in any appropriate manner such as molding, a pressed indentation or cutting.
  • the folded ceiling baffle can be provided in combination with an elongate support element.
  • the first top portion of the folded ceiling baffle is connected to a first elongate support edge of the elongate support element, and the second top portion of the folded ceiling baffle is connected to a second elongate support edge.
  • the combination of the folded ceiling baffle and the elongate support element can be used as a single baffle assembly to be supported by means connecting with the elongate support element.
  • the parts of the ceiling baffle for example in particular the first and second top portions, may be folded onto or into the elongate support element so as to connect with it. In this way it is relatively simple to construct the folded ceiling baffle together with the elongate support element.

  • the elongate support portion may extend in parallel with the first elongate support edge and the second elongate support edge.
  • the elongate support portion may be configured to receive mounting means for supportively suspending the folded ceiling baffle.

  • the elongate support portion may have a lipped channel cross-section.
  • supporting elements may be slidably received within the lipped channel and support the assembly by means of the lips of the channel.

  • the sheet of felt may be folded so that those respective portions together form the folded ceiling baffle.
  • the sheet of felt will have a thickness. Elongate recesses may be formed within that thickness. The recesses in the thickness may define fold lines between the respective parts of the ceiling baffle.
