Description

Technical field

The present invention relates to a suspension element for a suspended ceiling, more particularly for suspending a runner of a suspended ceiling along a suspension direction, according to the preamble of the first claim. Further, the present invention also relates to a suspended ceiling system for making a suspended ceiling, a suspended ceiling, and a method for making a suspended ceiling.

Background art

A Suspended ceiling for a construction, such as for example an office building, 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.
However, 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.
To prevent the suspension hook of the wire hanger from protruding substantially through the suspension opening, it is known from the state of the art to use an intermediate suspension element which is clamped onto the runner, and via which the runner is suspended from the wire hanger.
An example of such a 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.
Furthermore, 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.
In case the suspension element is already clamped on the runner, this requires the runner to be tilted over a tilt axis which is perpendicular to the longitudinal direction of the runner, such that the runner is aligned approximately with the suspension hook, after which the suspension hook can be positioned underneath the part of the suspension element connecting both legs of the suspension element. There is however not always sufficient space available between the suspension hook and the construction to tilt the runner in this way.
In case the suspension element is not yet clamped on the runner but already suspended on the suspension hook of the wire hanger, it becomes even more difficult to clamp the suspension element on the runner, because the suspension hook and the wire hanger hinder in pressing the suspension element on the bead of the runner.

Disclosure of the invention

It is an aim of the present invention to provide a suspension element which can easily and quickly be clamped on or removed from the bead of a runner.
This aim is achieved according to the invention with a suspension element showing the technical characteristics of the characterising part of the first claim.
Therefore, the present invention provides 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. Preferably, 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. Preferably, the clamping surface is spaced apart from the engaging element.
The suspension element 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.
Furthermore, the suspension element 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.
Furthermore, the suspension element 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.
In an embodiment of the suspension element according to the present invention 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.
In an embodiment of the suspension element according to the present invention the suspension element comprises an upright part. The upright part extends from the clamping surface in an upright direction away from the engaging element. Preferably, 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. 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.
In an embodiment of the suspension element according to the present invention 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. Preferably, 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.
In an embodiment of the suspension element according to the present invention 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. To make use of these suspension hooks, it is beneficial to provide the suspension means of the suspension element with the supporting element on which the suspension hook is to be hooked to suspended the suspension element from the hanger. Thereby providing a good connection is realised between the hanger and the suspension element for securely suspending the suspending element from the hanger via the hook.
In an embodiment of the suspension element according to the present invention 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. Only a slight tilting of the suspension element, and of a possible runner on which the suspension element is clamped, around a direction running from the first edge to the second edge of the supporting surface, may be required to keep other parts of the suspension element such as the clamping means, and possibly the runner, away from the suspension hook such that they cannot interfere in the supporting surface being supported on the first leg and the second leg of 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.
In an embodiment of the suspension element according to the present invention 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. Preferably, 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.
In an embodiment of the suspension element according to the present invention the engaging element comprises at least one barb. Preferably, 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.
In an embodiment of the suspension element according to the present invention 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.
In an embodiment of the suspension element according to the present invention 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.
In an embodiment of the suspension element according to the present invention 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 second side edge of the first upright flange is arranged opposite of the first side edge of the first upright flange. The first transverse flange and the second transverse flange are arranged on the same side 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.
In an embodiment of the suspension element according to the present invention 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.
In an embodiment of the suspension element according to the present invention the first transverse flange and the second transverse flange are arranged along converging, preferably slightly converging, directions.
With the first transverse flange and the second transverse flange arranged along converging, preferably slightly converging, directions, the engaging element formed by the first transverse flange is pointed slightly upwards towards the clamping surface provided by the second transverse flange, and the clamping surface is pointed slightly downwards towards the engaging element.
This embodiment of the suspension element 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.
Furthermore, this embodiment of the suspension element 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.
Furthermore, the inventors have also found this embodiment of the suspension element according to the present invention to be 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. 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. Thereby thus progressively clamping the suspension element on the bead of a runner without requiring much force. And the engaging element pointing slightly upwards aids in preventing the engaging element from disengaging from the suspension opening when the suspension element is being tilted.
In an embodiment of the suspension element according to the present invention the suspension element further comprises a second upright flange and a third transverse flange. The second upright flange connects with a first side edge to a second side edge of the second transverse flange. The second side edge of the second transverse flange is arranged opposite of the first side edge of the second transverse flange. The third transverse flange connects with a first side edge to a second side edge of the second upright flange. The second side edge of the second upright flange is arranged opposite of the first side edge of the second upright flange. The first upright flange and the second upright flange are arranged on opposite sides of the second transverse flange. The second transverse flange and the third transverse flange are arranged on the same side of the second upright flange. The third transverse flange forms the supporting element of the suspension means.
In an embodiment of the suspension element according to the present invention the third transverse flange provides the supporting surface of the supporting element. Preferably, the supporting surface of the supporting element is provided by the side of the third transverse flange which is facing the second transverse flange. The third transverse flange is provided such that the first edge of the supporting surface is formed by a third side edge of the third transverse flange. The third transverse flange is provided such that the second edge of the supporting surface is formed by a fourth side edge of the third transverse flange. The third side edge and the fourth side edge of the third transverse flange are arranged opposite of each other. The third side edge and the fourth side edge of the third transverse flange connect the first side edge of the third transverse flange and a second side edge of the third transverse flange. The second side edge of the third transverse flange is arranged opposite of the first side edge of the third transverse flange.
In an embodiment of the suspension element according to the present invention the suspension element further comprises a third upright flange. The third upright flange connects to a second side edge of the third transverse flange. The second side edge of the third transverse flange is arranged opposite of the first side edge of the third transverse flange. The second upright flange and the third upright flange are arranged on the same side of the third transverse flange.
The third upright flange at the second side edge of the third transverse flange is advantageous for preventing the supporting surface, provided by the third transverse flange, from sliding of the first leg and the second leg of the suspension hook at the second side edge of the third transverse flange, when the supporting surface supports with the first side edge on the first leg of the suspension hook and with the second side edge one the second leg of the suspension hook. At the first side edge of the third transverse flange the protection from the supporting surface sliding from the first leg and the second leg of the suspension hook is already provided by the second upright flange, and in this embodiment of the suspension element according to the present invention this protection is now also beneficially provided at the second side edge of the third transverse flange by the third upright flange.
In an embodiment of the suspension element according to the present invention the length of the third upright flange along the direction in which the third upright flange extends from the third transverse flange is substantially shorter than the length of the second upright flange along the direction in which the second upright flange extends from the third transverse flange.
The third upright flange being substantially shorter than the second upright flange offers the advantage that a sufficiently large opening is created between the third upright flange and the second transverse flange for arranging the suspension hook underneath the supporting surface, provided by the third transverse flange, via said opening, in order to support the supporting surface on the suspension hook. This is beneficial for hooking the suspension hook onto the supporting element without having to tilt the suspension element and the suspension hook with respect to each other. Only a slight tilting of the suspension element, and of a possible runner on which the suspension element is clamped, around a direction running from then first edge to the second edge of the supporting surface, may be required to keep other parts of the suspension element such as the clamping means, and possibly the runner, away from the suspension hook such that they cannot interfere in the supporting surface being supported on the first leg and the second leg of the suspension hook.
In an embodiment of the suspension element according to the present invention the suspension element comprises at least one connection opening. The suspension element is connectable to the runner with a connection means via the at least one connection opening. The connections means is for example a screw.
The at least one connection opening offers the advantage that it enables the suspension element according to an embodiment of the present to be additionally secured against the runner, besides clamping the suspension element on the bead of the runner with the clamping means of the suspension element. Such additional securing of the suspension element on the runner may for example be required for a suspended ceiling to meet certain structural requirements.

In an embodiment of the suspension element according to the present invention the suspension element is formed by a cut out and folded plate, preferably a cut out and folded metal plate.
The suspension element being formed by a cut out and folded plate is beneficial for quickly and easily manufacturing the suspension element by simply cutting the, preferably metal, plate to the desired shape, and folding the cut out plate into the suspension element.
In an embodiment of the suspension element according to the present invention the suspension element is manufactured from a material selected from the list consisting of plastic, metal, steel, spring steel and stainless steel. Preferably, the suspension element is manufactured from steel. More preferably, the suspension element is manufactured from stainless steel.
Steel offers the advantage of being a strong material, thereby providing the suspension element according to an embodiment of the present invention with the required structural strength for carrying the weight of a suspended ceiling. Steel also offers the advantage of having a high melting point, such that the suspension element is able to maintain its structural strength when being heated, for example in case of a fire. In addition thereto, stainless steel offers the advantage of corrosion resistance.

A first transverse flange 14 connects to a first side edge 111 of a first upright flange 11. The first upright flange 11 and the first transverse flange 14 are transverse to each other.
The first upright flange 11 connects at a second side edge 112, opposite of the first side edge 111 of the first upright flange 11, to a first side edge 151 of a second transverse flange 15. The second transverse flange 15 and the first upright flange 11 are transverse to each other. The second transverse flange 15 is arranged opposite of the first transverse flange 14. The second transverse flange 15 and the first transverse flange 14 are arranged at the same side of the first upright flange 11. The second transverse flange 15 and the first transverse flange 14 extend from the first upright flange 11 in approximately the same direction with the second transverse flange 15 tilted slightly towards the first side edge 111 of the first upright flange 11 and with the first transverse flange 14 tilted slightly towards the second side edge 112 of the first upright flange 11, such that the second transverse flange 15 and the first transverse flange 14 extend from the first upright flange 11 in slightly or slowly converging directions.
The second transverse flange 15 connects at a second side edge 152, opposite of the first side edge 151 of the second transverse flange 15, to a first side edge 121 of a second upright flange 12. The second upright flange 12 and the second transverse flange 15 are transverse to each other. The second upright flange 12 and the first upright flange 11 are arranged on opposing sides of the second transverse flange 15, and extend from the second transverse flange 15 in opposite directions.
The second upright flange 12 connects at a second side edge 122, opposite of the first side edge 121 of the second upright flange 12, to a first side edge of a third transverse flange 16. The third transverse flange 16 and the second upright flange 12 are transverse to each other. The third transverse flange 16 is arranged opposite of the second transverse flange 15. The third transverse flange 16 and the second transverse flange 15 are arranged at the same side of the second upright flange 12. The third transverse flange 16 and the second transverse flange 15 extend from the second upright flange 12 in approximately the same direction with the third transverse flange 16 perpendicular to the second upright flange 12 and with the second transverse flange 15 tilted slightly towards the second side edge 122 of the second upright flange 12.
The third transverse flange 16 connects at a second side edge 162, opposite of the first side edge 161 of the third transverse flange 16, to a third upright flange 13. The third upright flange 13 and the third transverse flange 16 are transverse to each other. The third upright flange 13 is arranged opposite of the second upright flange 12. The third upright flange 13 and the second upright flange 12 are arranged on the same side of the third transverse flange 16, and extend from the third transverse flange 16 in the same direction.
The suspension element 10 having the configuration of the different upright flanges 11, 12, 13 and transverse flanges 14, 15, 16 as described above, is substantially S-shaped.
The suspension element 10 is provided for being clamped on the bead 21 of a runner 20, such as shown in Figures 5 and 6. Therefore, the suspension element 10 is provided with clamping means 17. Said clamping means 17 comprise an engaging element 171 and a clamping surface 173. The engaging element 10 is provided for being engaged in a suspension opening 24 of the runner 20 when the suspension element 10 is clamped on the bead 21 of the runner 20, or said otherwise when the suspension element 10 is positioned in a clamping position on the runner 20. The clamping surface 173 is provided for clamping on a top part 210 of the bead 21 of the runner 20 when the suspension element 10 is positioned on the runner 20 in the clamping position.
In the embodiment of the suspension element 10 shown in Figures 1 and 2, the engaging element 171 of the clamping means 17 is formed by the first transverse flange 14 of the suspension element 10. The first transverse flange 14 is dimensioned such that it is insertable through the suspension opening 24 of the runner 20 for engaging the engaging element 171 formed by first transverse flange 14 in the suspension opening 24.
The engaging element 171 is provided with two barbs 172, which are arranged opposite from each other and pointing away from each other. The barbs 172 are provided for hooking behind the edge of the suspension opening 24 when the engaging element 171 is engaged in the suspension opening 24, such as shown most clearly in Figure 6. In this way, the engaging element 171 is prevented from leaving or disengaging from the suspension opening 24.
In the embodiment of the suspension element 10 shown in Figures 1 and 2, the clamping surface 173 is provided by the second transverse flange 15, more specifically by the side of the second transverse flange 15 facing the first transverse flange 14.
The first upright flange 11 connects the engaging element 171 to the clamping surface 173, and is arranged with respect to the engaging element 171 and the clamping surface 173 such that in the clamping position of the suspension element 10 on the runner 20 the first upright flange 11 is adjacent to and supports against the bead 21 of the runner 22. This configuration aids in aligning the suspension element 10 with respect to the runner20, and provides additional support for the suspension element 10 on the runner 20.
The first upright flange 11 is provided with connection openings 192. These connection openings 192 are provided for attaching the suspension element 10 against the runner 20 with a connection means 50 such as for example a screw 50, as can be seen in Figures 8 and 9. Therefore, it is also beneficial that the first upright flange 11 is adjacent to the bead 21 of the runner 20 in the clamping position of the suspension element 10 on the runner 10, because in this way the screw 50 can be screwed directly into the bead 21 via the connection opening 192.
The suspension element 10 is provided for being suspended from the suspension hook 31 of a wire hanger 30, such as shown in Figures 7-10. Therefore, the suspension element 10 is provided with suspension means 18. Said suspension means 18 comprises a supporting element 181 which is provided for hooking the suspension hook 31 of the wire hanger 30 thereon.
In the embodiment of the suspension element 10 shown in Figures 1 and 2, the supporting element 181 comprises a supporting surface 182. The supporting surface is provided for supporting with a first edge 183 on a first leg 311 of the suspension hook 31 and for supporting with a second edge 184 on a second leg 312 of the suspension hook 31, while the suspension hook 31 is hooked onto the supporting element 181 for suspending suspension element 10 from the suspension hook 31 of the wire hanger 30.
In the embodiment of the suspension element 10 shown in Figures 1 and 2, the supporting element 181 is formed by the third transverse flange 16, and the supporting surface 182 is provided by the third transverse flange 16, more specifically by the side of the third transverse flange 16 facing the second transverse flange 15. The first edge 183 of the supporting surface 182 is formed by a third side edge 163 of the third transverse flange 16, which third side edge 163 connects the first side edge 161 and the and the second side edge 162 of the third transverse flange 16. The second edge 184 of the supporting surface 182 is formed by a fourth side edge 164 of the third transverse flange 16, which fourth side edge 164 connects the first side edge 161 and the and the second side edge 162 of the third transverse flange 16, and which fourth side edge 164 is arranged opposite of the third side edge 163 of the third transverse flange 16.
To prevent the first leg 311 of the suspension hook 31 from moving on the first edge 183 of the supporting surface 182 out of a desired position on the first edge 183 of the supporting surface 182, the first edge 183 of the supporting surface 182 is provided with a first recess 185 in which the first leg 311 of the suspension hook 31 can be positioned. And to prevent the second leg 312 of the suspension hook 31 from moving on the second edge 184 of the supporting surface 182 out of a desired position on the second edge 184 of the supporting surface 182, the second edge 184 of the supporting surface 182 is provided with a second recess 186 in which the second leg 312 of the suspension hook 31 can be positioned.
Protection to prevent the first leg 311 and the second leg 312 from moving of the supporting surface 182 is provided at the first side edge 161 of the third transverse flange 16 by the second upright flange 12 and at the second side edge 162 of the third transverse flange 16 by the third upright flange 13.
In the embodiment of the suspension element 10 shown in Figures 1 and 2, the third upright flange 13 is substantially shorter than the second upright flange 12 to leave space between the third upright flange 13 and the second transverse flange 15. Via this space the suspension hook 31 of the wire hanger 30 is easily arranged underneath the supporting element 181 for supporting the supporting surface 182 of the supporting element 181 on the suspension hook 31 of the wire hanger 30. This, without first having to tilt the first leg 311 of the suspension hook 31 and the supporting surface 182 with respect to each other in such a way that the first leg 311 of the suspension hook 31 is approximately parallel to the supporting surface 182. Only a slight tilting of the first leg 311 and the second leg 312 of the suspension hook 31 with respect to the first upright flange 11 of the suspension element 10 may be required to prevent the first upright flange 11 from hindering in arranging the suspension hook 31 underneath the supporting element 181. This slight tilting requires less movement of the wire hanger 31 and the suspension element 10, and possibly a runner 20 connected thereto, with respect to each other, and is thus easier to perform than fully tilting the first leg 311 of the suspension hook 31 to be approximately parallel to the supporting surface 182 of the suspension element 10. This is certainly beneficial when installing a suspended ceiling, since there is not always sufficient space available for moving the components of the suspended ceiling, such as the wire hangers 30, the suspension elements 10 and the runners 20 around.
The suspension element 10 is provided with a longitudinal protrusion 191, which runs from the first transverse flange 14 toward the second side edge 162 of the third transverse flange 16. The longitudinal protrusion 191 provides additional strength to the suspension element 10.
Now, the different steps for clamping the suspension element 10 on the bead 21 of a runner 20 will be discussed with respect to Figures 3 and 4.
In a first step, as can be seen in Figure 3, the suspension element 10 is positioned in front of the runner 20, with the engaging element 171 formed by the first transverse flange14 pointed towards the suspension opening 24 in the upright web 22 of the runner 20. Then, as indicated by the arrow, the suspension element 10 is moved towards the runner 20, for inserting the engaging element 171 centrally through the suspension opening 24. After the engaging element 171 has been inserted through the suspension opening 24, the suspension element 10 is moved slightly upwards along the suspension direction, such that the engaging element 171 moves upwards in the suspension opening and the barbs 172 of the engaging element 171 hook behind the edge of the suspension opening 24. This step is performed with the suspension element 10 being tilted with respect to the runner 20, more specifically the upright web 22 of the runner 20, in such a way that the clamping surface 173 of the suspension element 10 does not yet contact the top part 210 of the bead 21 of the runner 20 when the engaging element 171 is engaged in the suspension opening.
In a second step, as can be seen in Figure 4, the suspension element 10 is tilted towards the runner 20 around a tilting axis going through the suspension opening 24 and approximately parallel to the longitudinal direction of the runner 20. By tilting the suspension element 10 the clamping surface 173 is moved and clamped onto the top part 210 of the bead 21 of the runner 20.
If desired, the suspension element 10 can be attached further to the runner 20 by screwing screws 50 through the connection openings 192 of the suspension element 10 into the bead 21 of the runner 20.
For suspending the suspension element 10 from a wire hanger 30, the suspension element 10 is positioned in front of the suspension hook 31 of the wire hanger 30 with the second side edge 162 of the third transverse flange 16 towards the suspension hook 31. Thereby, the suspension element 10 is positioned such that the supporting element 181 formed by the third transverse flange 16 can pass between the first leg 311 and the second leg 312 of the suspension hook. Thereby, the suspension element 10 and the suspension hook 31 are arranged such that the first leg 311 and the second leg 312 of the suspension hook 31 are slightly tilted with respect to the upright flanges 11, 12, 13 of the suspension element.
Then, the suspension element 10 and the wire hanger 30 are moved towards each other to position the supporting element 181 between the first leg 311 and the second leg 312 of the suspension hook 31 with the first recess 185 of the first edge 183 of the supporting surface 182 positioned above the first leg 311 of the suspension hook 31 and with the second recess 186 of the second edge 184 of the supporting surface 182 positioned above the second leg 312 of the suspension hook 31. Thereafter, the suspension element 10 is lowered onto the suspension hook 31 until the first edge 183 of the supporting surface 182 supports on the first leg 311 with the first leg 311 positioned in the first recess 185 of the first edge 183 of the supporting surface 182, and until the second edge 184 of the supporting surface 182 supports on the second leg 312 with the second leg 312 positioned in the second recess 186 of the second edge 184 of the supporting surface 182.
