Definitions

  • the present invention relates to a suspended ceiling system for making a suspended ceiling, a suspended ceiling, and a method for making a suspended ceiling.
  • a Suspended ceiling for a construction typically comprises a series of runners for supporting ceiling tiles which are suspended from the construction by means of wire hangers.
  • Such wire hangers are usually provided with suspension hooks at their end parts for hooking into a suspension opening of the runners of the suspended ceiling at one side and for further attachment to the construction at the other side.
  • the hook hooking into the suspension opening in the runner protrudes substantially from the suspension opening from one side of the runner to the opposing side of the runner such that when ceiling tiles are being provided on the runners of the suspended ceiling, the hook may hinder the desired location of the ceiling tiles and for example may cause the ceiling tiles to be shifted, dislocated, etc. or can even become damaged.
  • suspension element is the ECOPHON Connect Hanger clip indicated by ECOPHON as 26311286.
  • This suspension element comprises two legs which are connected to each other at one end. Further, the legs are provided such that free ends of the legs press against each other, but can still be moved away from each other by applying a force on the legs pulling the legs apart. This enables the suspension element to be clamped on a bead of a runner, with the free ends of the legs pressing against opposing sides of an upright web of the runner, and with the legs themselves pressing against opposing sides of the bead of the runner. Then, to suspend the suspension element from a wire hanger, a suspension hook at an end part of the wire hanger is arranged underneath the part of the suspension element connecting both legs of the suspension element.
  • Such a suspension element however has the disadvantage that it is difficult to clamp the suspension element onto the bead of the runner or to remove, or unclamp, the suspension element from the bead of the runner. This, because a certain amount of force is required to pull the legs of the suspension element sufficiently apart, such that the suspension element can be clamped onto the bead or removed from the bead.
  • such a suspension element also has the disadvantage that, in case the wire hangers are already attached against the construction, it is difficult to arrange the suspension hook of the wire hanger underneath the part of the suspension element connecting the two legs of the suspension element.
  • BE 900 449 A1 discloses a suspended ceiling system comprising at least one runner and at least one suspension element, wherein the runner is inserted in openings of the suspension element and is secured to the suspension element by noses provided with resilient lips.
  • the present invention provides as part of a suspended ceiling system a suspension element for suspending a runner of a suspended ceiling along a suspension direction.
  • the suspension element comprises a clamping means provided for clamping the suspension element on a bead of the runner.
  • the clamping means comprises an engaging element and a clamping surface.
  • the engaging element is engageable in a suspension opening of the runner.
  • the clamping surface is adapted to clamp on a top part of the bead of the runner in a clamping position of the suspension element on the runner where the engaging element is engaged in the suspension opening of the runner.
  • the clamping surface is arranged with respect to the engaging element such that in a clamping position of the suspension element on the runner the clamping surface clamps on a top part of the bead of the runner when the engaging element is engaged in the suspension opening of the runner.
  • the clamping surface is spaced apart from the engaging element.
  • the suspended ceiling system of the present invention offers the advantage that less force is required to clamp the suspension element on the bead of the runner, because only the clamping surface needs to be pushed over the top part of the bead of the runner to clamp the suspension element on the bead of the runner. Also, less force is required to remove or unclamp the suspension element from the bead of the runner, because only the clamping surface needs to be pushed off the top part of the bead of the runner. This makes it thus easier to clamp the suspension element on the bead of the runner or to remove the suspension element from the bead of the runner, and allows the suspension element to be clamped on or removed from the suspension element more quickly.
  • the suspended ceiling system of the present invention also offers the advantage that while less force is required for clamping the suspension element on the bead of the runner, the suspension is still securely attached to the runner in the clamping position of the suspension element on the runner. This, because of the engaging element being engaged in the suspension opening of the runner, thereby providing a first attachment of the suspension element on the runner, and because of part of the runner being clamped between the engaging element and the clamping surface, thereby providing a second attachment of the suspension element on the runner.
  • the suspended ceiling system of the present invention also offers the advantage that the suspension element can be clamped on the runner at one side of the runner. This makes it easier to clamp the suspension element on the runner or to remove the suspension element from the runner, since only access to one side of the runner is required.
  • the clamping means is provided such that the suspension element, when the engaging element is engaged in the suspension opening, is moveable in and out of the clamping position of the suspension element on the runner by means of tilting the suspension element with respect to the runner around a tilting axis passing through the suspension opening and approximately parallel to a longitudinal direction of the runner.
  • the inventors have found that providing the suspension element for being tiltable in and out of the clamping position while the engaging element is engaged in the suspension opening, is beneficial for pushing the clamping surface on or of the top part of the bead of a runner without requiring much force. Thereby, making it easier to clamp the suspension element on the bead of a runner or to remove the suspension element from the bead of a runner, and allowing the suspension element to be clamped on or removed from the suspension element more quickly.
  • the suspension element comprises an upright part.
  • the upright part extends from the clamping surface in an upright direction away from the engaging element.
  • the upright direction is substantially perpendicular to the clamping surface.
  • the upright part offers the advantage of functioning as a lever for pushing the clamping surface on or of the top part of the bead of a runner, thereby requiring even less force to clamp the suspension element on the bead of the runner and to remove the suspension element form the bead of a runner.
  • the upright part offers the advantage of functioning as a lever for pushing the clamping surface on or of the top part of the bead of a runner, thereby requiring even less force to clamp the suspension element on the bead of the runner and to remove the suspension element form the bead of a runner.
  • the suspension element comprises a suspension means.
  • the suspension means is provided for suspending the suspension element.
  • the suspension means is connected to the clamping means.
  • the suspension means, or at least part of the suspension means forms the upright part of the suspension element.
  • the suspension means are beneficial for suspending a runner from a construction via the suspension element.
  • the suspensions means, or at least a part of the suspension means, forming a part of the upright part of the suspension element is beneficial for providing the upright part to the suspension element without the need of additional means. Therefore, simplifying the design of the suspension element.
  • the suspension means is provided for suspending the suspension element from a hanger.
  • the hanger is provided with a suspension hook at an end part of the hanger.
  • the suspension means of the suspension element comprises a supporting element.
  • the supporting element is provided for hooking the suspension hook onto for suspending the suspension element.
  • Commonly used hangers are provided with a suspension hook on at least one end part of the hanger.
  • the supporting element comprises a supporting surface.
  • the supporting surface is provided for supporting with a first edge on a first leg of the suspension hook when the suspension element is suspended from the hanger.
  • the supporting surface is provided for supporting with a second edge on a second leg of the suspension hook when the suspension element is suspended from the hanger.
  • the first leg and the second leg of the suspension hook are inclined with respect to each other.
  • the supporting element comprising the supporting surface provided for supporting with the first edge on the first leg of the suspension hook and for supporting with the second edge on the second leg of the suspension hook, offers the advantage that the suspension hook is easily hooked onto the support element of the suspension means, without requiring much manoeuvring space. Therefore, the supporting surface only needs to be positioned between the first leg and the second leg of the suspension hook, and then lowered until the first edge of the supporting surface supports on the first leg of the suspension hook and until the second edge of the supporting surface supports on the second leg of the suspension hook. Thus, only a limited amount of manoeuvring space is required to suspend the suspension element from the suspension hook.
  • the supporting surface being provided for supporting with the first edge on the first leg of the suspension hook and for supporting with the second edge on the second leg of the suspension hook, is also beneficial for changing the inclination of the suspension element, and of a possible runner on which the suspension element is clamped, with respect to the hanger if the application in a suspend ceiling may require this.
  • the first edge of the supporting surface is provided with a first recess.
  • the first recess is provided for positioning the first leg of the suspension hook of the hanger therein when the suspension element is suspended from the hanger.
  • the second edge of the supporting surface is provided with a second recess.
  • the second recess is provided for positioning the second leg of the suspension hook of the hanger therein when the suspension element is suspended from the hanger.
  • the first recess in the first edge of the supporting surface is beneficial for securing the first leg of the suspension hook at a predetermined position along the first edge of the supporting surface. This has the advantage of preventing the suspension hook and the suspension element from being disconnected, for example by the first edge of the supporting surface sliding of the first leg of the suspension hook.
  • the second recess in the second edge of the supporting surface benefits from the same advantage with respect to the second leg of the suspension hook.
  • the engaging element comprises at least one barb.
  • the engaging element comprises at least two barbs.
  • the at least one barb is provided for preventing the engaging element from leaving the suspension opening of the runner when the engaging element is engaged in the suspension opening of the runner.
  • the at least one barb offers the advantage that the engaging element is easily insertable through the suspension opening for engaging the engaging element in the suspension opening. Subsequently, the at least one barb offers the advantage that the at least one barb prevents the engaging element from leaving or disengaging from the suspension opening by hooking behind the edge of the suspension opening. This securely engages the engaging element in the suspension opening, thereby contributing to an improved clamping of the suspension element on the bead of the runner.
  • the engaging element being provided with at least two barbs offers the advantage that the engaging element hooks at different positions behind the edge of the suspension opening, thereby even more securely engaging the engaging element in the suspension opening.
  • the at least one barb has a predetermined size with respect to the size of the suspension opening of the runner.
  • the predetermined size is such that the engaging element is insertable through the suspension opening of the runner in at least one orientation of the engaging element.
  • the predetermined size is such that the at least one barb hooks behind the edge of the suspension opening of the runner when the engaging element is moved along the suspension direction in the suspension opening.
  • the at least one barb being provided such that the engaging element is insertable through the suspension opening in at least one orientation, and such that the at least one barb hooks behind the edge of the suspension opening when the engaging element is subsequently moved along the suspension direction, offers the advantage that the engaging element is secured strongly in the engaged position through the suspension opening when the suspension element is suspended from the construction along the suspension direction, which moves the engaging element along the suspension direction in the suspension opening.
  • the suspension element is provided with a longitudinal protrusion.
  • the longitudinal protrusion runs along the surface of the suspension element.
  • the longitudinal protrusion extends along the suspension direction.
  • the longitudinal protrusion offers the advantage of providing additional strength to the suspension element, which protects the suspension element from being deformed and/or damaged by the forces to which the suspension element is exposed when used in a suspended ceiling, such as for example the gravitational forces caused by the weight of the runners and the ceiling tiles supporting on the runners.
  • the suspension element comprises a first upright flange, a first transverse flange and a second transverse flange.
  • the first transverse flange connects to a first side edge of the first upright flange.
  • the second transverse flange connects with a first side edge to a second side edge of the first upright flange.

  • the first transverse flange forms the engaging element of the clamping means of the suspension element.
  • the second transverse flange provides the clamping surface of the clamping means of the suspension element.
  • the suspension element being composed of the different flanges, as described for this embodiment and following embodiments, offers the advantage that the suspension element is easily formed out of a straight piece of foldable material by folding the piece to the desired shape of the suspension element.
  • the first upright flange is arranged with respect to the first transverse flange and the second transverse flange such that the first upright flange is adjacent to, preferably thereby supporting against, the bead of the runner when the suspension element is positioned in the clamping position on the runner.
  • the inventors have found that arranging the first upright flange such that in the clamping position of the suspension element on the bead of the runner the first upright flange is adjacent to the bead of the runner, offers the advantage of the first upright flange correctly aligning the suspension element with respect to the runner.
  • the first upright flange arranged as such also offers the advantage that the first upright flange provides the suspension element additional support on the bead of the runner in the clamping position of the suspension element of the bead of the runner.
  • the first transverse flange and the second transverse flange are arranged along converging, preferably slightly converging, directions.

  • This embodiment of the suspended ceiling system according to the present invention offers the advantage that the engaging element can be engaged more securely in the suspension opening, because of the slightly upwards pointing engaging element hooking behind the edge of the suspension opening.
  • this embodiment of the suspended ceiling system according to the present invention also offers the advantage that the clamping surface can be clamped more strongly on the top part of the bead of a runner, because of the slightly downwards pointing clamping surface pressing tightly against the top part of the bead of the runner.
  • this embodiment of the suspended ceiling system according to the present invention is beneficial for providing the suspension element such that the suspension element is tiltable in and out of the clamping position while the engaging element is engaged in the suspension opening.
  • the clamping surface With the clamping surface pointing slightly downwards, the clamping surface will approximately be aligned with the top part of the bead of the runner when the suspension element is tilted close to the runner, such that the clamping surface can initially be moved easily over the top part of the bead and clamps increasingly on the top part of the bead while the suspension element is tilted further onto the top part of the bead.
