Description

BACKGROUND OF THE INVENTION

Suspended ceiling systems provide a grid structure for suspending light-weight panels to form a ceiling in commercial environments such as office or retail spaces. The panels can be used to hide the upper space of a room which can contain wiring, conduit, piping or ductwork. Designers often desire the installation of visually different suspended ceilings other than those that can suspend standard square or rectangular panels. However this can involve complex and expensive installation.

Examples of the invention seek to avoid or to at least ameliorate problems of existing suspended ceiling systems.

DETAILED DESCRIPTION

FIGS. 1 to 3A are views of assemblies 2, 4 for suspending ceiling panels 6 having respectively a frame 8 or two frames 8, 10, and suspension members 12 according to preferred embodiments of the present invention. The suspension members 12 are for suspending the frames 8, 10 from structure, such as an interior surface of a roof or a ceiling of a room.

The frames 8, 10 have intersection members 14, 16 and support members 18 extending therebetween where each support member 18 supports a side of one of the ceiling panels 6. The intersection members 14, 16 have a generally tubular, axially extending, mounting member 19 and a base 15, which base is lowermost in use of the intersection member. The base 15 extends outwardly around the periphery of the mounting member 19, as a peripheral flange. The ends of the support members 18 are configured to engage with engageable portions 20 provided circumferentially about each of the intersection members 14, 16, the engageable portions 20 defining respective slot-like apertures which extend through the side wall of mounting member 19. Together, the support members and intersection members form a support grid having openings principally defined at the peripheries by the support members 18. The shape of these openings corresponds to the shape of the ceiling panels 6, each side of the ceiling panel 6 being supportable by a respective support member 18. That is, the support members 18 have flanges 13 on lower opposite longitudinal edges which receive thereon underside marginal portions of the ceiling panels 6, thereby supporting the ceiling panels 6 to form a suspended ceiling as shown in FIG. 3A.

FIGS. 3B to 3K show more detailed examples of the engagement of the support members 18 with the intersection member 14 or 16, where the engageable portions 20 are provided as apertures 11 which are adapted to receive protrusions 17 provided at the opposite ends of the support members 18. Alternatively, the engageable portions may be in the form of protrusions which are receivable in apertured portions provided at the opposed ends of the support members 18.

In the embodiment shown in FIGS. 3B, 3C, 3G and 3K, the illustrated protrusion 17 is latchingly engaged in an aperture 11. In an alternative embodiment shown in FIGS. 3D to 3J, the protrusion 17 is latchingly engaged laterally in the aperture 11. Both embodiments will be described further below. In any case, in FIGS. 3A to 3K, the intersection members 14, 16 are shown with the engageable portions 20 in the form of the described apertures 11 formed through the side wall 19a of the mounting member 19 and being arranged towards an end of the mounting member adjacent to the base 15 of the intersection member 14, 16. The locating member 23 is in the form of a punched-out resilient tongue extending sidewardly, and outwardly at an acute angle, from the remainder of the protrusion 17. Referring to FIGS. 3H, 3I and 3J, the width S of the aperture 11 is only slightly greater than the width W1 of the main body of the protrusion 17. At the location of the free end 23a of the locating member 23, the width W2 is greater than the width S. As the protrusion 17 is inserted into the aperture 11 (in the direction indicated by arrow A), one side edge 11a of the aperture 11 engages the locating member 23 such that the locating member 23 is depressed inwardly (in the direction indicated by arrow B) of the protrusion 17 by camming action against natural resilience of the locating member, the opposite face 17a of the protrusion 17 engaging the adjacent opposite surface 11b of the aperture 11. By this camming action, the protrusion 17 can pass through the aperture 11 until the locating member 23 has passed through it. Once the locating member 23 is clear of the aperture 11, the free end 23a of the locating member 23 moves outwardly under resilient bias (in the direction indicated by arrow C in FIG. 3J) from the protrusion 17 so that withdrawal of the support member 18 is inhibited by engagement of the free end 23a of the locating member 23 with the inner surface 19b of the side wall 19a of the mounting member 19 forming part of the intersection member 14 or 16.

In the arrangement shown in FIGS. 3B, 3C, 3G and 3K, further inward movement of the protrusion 17 may be inhibited by engagement of a transverse locating member 29 on support member 18 and the base 15 of the intersection member 14 or 16. Thus an outer edge surface 15a of the base 15 engages a surface 13a of the flange 13. As exemplified in FIG. 3F, the protrusion 17 may have locating members 25 and/or 27 to provide an alternative engagement to inhibit further movement of the protrusion 17 into intersection member 14 or 16. Referring to FIG. 3K, additionally or alternatively, inwards movement of the protrusion 17 into the aperture 11, as mentioned, may be limited by engagement between a side edge 15a of the base 15 of the intersection member 14, 16 and a lower transverse 13a surface of the flanges 13 of the support member 18. A transverse locating member 29, forming parts of flange 13, extends side to side of the support member 18, slightly above the main lengthwise extending parts 13b (FIG. 3K) of the flanges 13, so as to define a step between the flanges and the transverse locating member 29. It is at this step that the surface 13a is defined; that is, as an end surface of flange parts 13b. Also as shown in FIG. 3K, in the assembled condition of the support member 18 and intersection member 14 or 16, the transverse locating member 29 rests on the base 15 so as to additionally or alternatively support the support member. Additionally or alternatively, inwards insertion of the protrusion may be limited by providing on the protrusion 17 a further locating member 28, shown in phantom lines in FIGS. 3J and 3K and in the form of a punched out tongue, like locating member 23, but oppositely directed, and with its free end 28a spaced from the free end of locating member by a distance substantially the same as the thickness of the wall 19a. As the protrusion reaches the latched position, shown in FIGS. 3J and 3K, the free end 18a is as shown brought into engagement with the outer surface of the wall 19a, to prevent further inwards movement.

The intersection members 14, 16, shown in FIGS. 6 to 8b, have engageable portions 20 arranged equiangularly about the circumference of the intersection members 14, 16 wherein the angles formed between the engageable portions 20 and an axis 21 of the intersection members 14, 16 are represented as angle A, which corresponds to 60° (see FIG. 8a). This angle A corresponds to the angle of a corner of an equilateral triangle, known as an interior angle. Therefore the assemblies 2, 4 having intersection members 14, 16 and support members 18 form a grid 22 in which there are openings which can suspend ceiling panels 6 in the shape of equilateral triangles to form a suspended ceiling 24.

The same intersection members 14, 16 and support members 18 can be used to form a grid 26 whereby the ends of adjacent support members 18 engaged in intersection members 14, 16 form an angle of 120° represented as B in FIGS. 5, 8a and 10. Angle B is the interior angle of a hexagon. The openings of the grid 26 therefore can receive and suspend hexagonal shaped ceiling panels 25, see FIGS. 5, 8a and 10. The same intersection members 14, 16 can be used to form an assembly for suspending panels of equilateral triangle shape or hexagonal shape or a combination therefore, depending on the configuration of members 14, 16, 18.

Further embodiments of the present invention are directed to similar assemblies as described above but for suspending ceiling panels having square, octagonal or pentagonal shaped ceiling panels, see FIGS. 11 to 19. The angle between ends of adjacent support members engaged in the intersection members 36, 38, 40 can form angles C, D and E being respectively angles of 90°, 135° and 108° (corresponding to the interior angles of quadrilaterals, octagons and pentagons) to form the exemplary grids 42, 44, 46. The openings of grids 42, 44, 46 can receive ceiling panels having the shapes of squares, octagons and pentagons. While the grid 42 is for suspending square ceiling panels, it can be understood that any quadrilateral ceiling panels, such as rectangular panels could be utilized by varying the length of the support members 18 as appropriate.

FIG. 3A is a view of an assembly having two frames 8, 10 in a spaced apart vertical configuration. The intersection member 14, 16 of each frame 8, 10 is engageable with the suspension members 12 such that one intersection member 16 of the two frames 8, 10 is supported above the other intersection member 14, each frame being able to receive at least one ceiling panel 6. The intersection members 14, 16 attach to the suspension members 12 by a fastener 50 such as a suspension clip. The fastener 50 is releasably attachable to the suspension member 12 such that the intersection member 14, 16 can be movably adjustable along the length of the suspension member 12, which can be in the form of a rod, to allow adjustment of the vertical distance between the frames 8, 10 or the adjustment of the height of the suspended ceiling. The intersection members 14, 16 can be attached to the fasteners 50, in particular the lower end portion of the fastener 50 is configured as a hook 58 which can be received in an apertured portion 52 of the intersection members 14, 16.

Each intersection member 16 on an upper portion of the suspension member 12 has an opening 54 configured to allow the suspension member 12 to be received therethrough such that an axis of the suspension member 12 is substantially parallel to an axis of the intersection member 16 so that the intersection members 14, 16 are spaced-apart substantially vertically one above the other. As shown more particularly in FIG. 8b, the aperture 54 is substantially the size of the diameter of the suspension member 12 and is preferably centrally located within a base 15 of the intersection member 16. In a preferred embodiment, there is a transverse element internal to the intersection member 16, the transverse element 55 having a second aperture 57 and where the transverse element 55 is spaced apart from the base 15 along the longitudinal axis within the body of the intersection member 16 to ensure that the intersection members 14, 16 are accurately positioned vertically, one above the other.

An example suspended ceiling 24 having three levels is shown in FIG. 4. Further frames could be engaged with the suspension members 12 so as to provide a suspended ceiling with four or more levels. Alternatively the assemblies can be arranged with the intersection members 36, 38, 40 as shown in FIGS. 12, 13, 15, 16 and 19 so as to form a suspended ceiling with one or more levels having quadrilateral, pentagonal or octagonal shaped ceiling panels or combinations thereof.

It will be apparent that in the described assemblies of completed form can have ceiling panels received in the openings so that the ceiling panels present a complete false ceiling. In the suspended ceiling having two or three levels, each level does not need to be occupied by ceiling panels so they are viewed from below of complete coverage. To provide such coverage, ceiling panels 60 can be received between adjacent intersection members 14, 16 on the same suspension member 12 such that the ceiling panels 60 lie perpendicular to the plane of the frames 8, 10.

In an example use of the present invention, a user can assemble a suspended ceiling with ceiling panels having an equilateral triangle shape 6. The user can first assemble a frame 8 with intersection members 14 where the ends of six support members 18 are engaged with each of the six engageable portions 20 provided equiangularly about each of the intersection members 14 so as to form a grid 22, see FIG. 9. The ends of adjacent support members 18 form an angle A of 60° (the interior angle of an equilateral triangle). The user can then attach each intersection member 14 to a fastener 50 on a rod-shaped suspension member 12, the top portion of which is fixed to structure such as a ceiling of a room or an interior surface of a roof. The suspended ceiling 24 is thereby formed when the user provides equilateral triangle shaped ceiling panels 6 in the correspondingly shaped recesses formed by the grid 22, the panels being held in the respective recesses by flanges provided on the support members 18.

In order to form a suspended ceiling with multiple levels, the user can assemble a second frame 10 which is spaced apart vertically above the first frame 8, in the same way as described for the first frame 8 above. The user can then attach the second frame 10 to an upper portion of the suspension member 12 by a second fastener 50. The resultant assembly has first and second frames 8, 10 which are substantially parallel but spaced apart as shown in FIG. 3A.

Similarly, a user can form assemblies for suspending ceiling panels having a quadrilateral, hexagonal, pentagonal or octagonal shapes with the intersection members 14, 16, 36, 38, 40 and support members 18 of FIGS. 12, 13, 15, 16 and 19. In the example of octagonal shaped ceiling panels, each intersection member 38 receives ends of three support members 18 to form two angles D of 135° and one angle C of 90° thereby forming the grid 32 having both octagonal and square shaped recesses to configured to receive correspondingly shaped octagonal and square ceiling panels, see FIG. 16. Although eight engageable portions 20 are shown on the intersection member 38, clearly at a minimum only three engageable portions which form the two angles D of 135° and one angle C of 90° as described above would be necessary to form the required assembly. It can be understood that the intersection members 38 may also be used to form a grid 30 for suspending ceiling panels having only quadrilateral shaped recesses.

FIGS. 9 to 11, 14 show exemplary grids which are substantially planar, however FIGS. 18 and 19 are schematic diagrams showing an opening 46 for suspension of a pentagonal shaped ceiling panel which is the apex of a dome-like grid 62. The dome-like grid 62 is formed by intersection members 40 that can have two adjacent support members 18 engaged therein to form an angle which corresponds to the interior angle of a pentagon, represented as angle E of 108°. The other support member 64 forms angles, B′ of 126° each, with the first two adjacent support members 18. If the support members 64 are angled away, for example downwards or upwards from the plane of the pentagonal shaped opening 46, the angle formed by the support members 18, 64 decreases to 120°, represented as angle B, to accommodate the interior angle of a hexagon shaped ceiling panel, thereby forming the dome-like grid 62.

The described formation of the intersection members 14, 16, 36, 38, 40, as having engageable portions in the form of slot like apertures enables these to be used to interconnect with support members 18 of a variety of commercially available ceiling support systems. The support members of these systems generally have inverted T-shaped cross sectional form with a central web, upright in use, and sidewardly extended flanges, one to either side of the central web and at a lower edge of the central web in use of the support members. Notwithstanding this similarity, support members from different systems are generally incompatible with each other in the sense that the end protrusions of the support members and the configuration of slots, formed in the central webs, and, which accept the end protrusions are differently configured, such that interchangeability is precluded. This incompatibility may for example particularly arise because intersections between support members are formed by passing end protrusions of two support members oppositely into a single slot in another support member, such that the protrusions cooperate with each other and with the slot to effect latching. On the other hand, with the described arrangements of this invention, this incompatibility problem is lessened because the engageable portions 20 only need to accommodate one protrusion. It has been found that forming the engageable portions 20 as elongate rectangular apertures of about 3 mm width by 12 mm length, in the axial direction of the intersection member, enables protrusions of various commercially available support members to be used in practicing the invention. The dimensions of the rectangular apertures can vary in length by one or two mm so as to accommodate the variable dimensions of the commercially available support members, so that the apertures can be between 11 to 13 mm in length and 1 to 3 mm wide.

As particularly illustrated, these apertures may terminate close to the base 15 and with the longer dimensions of the slots aligned in the axial direction of the intersection members. The length of the apertures 11 in the axial direction of the intersection members may be chosen to suit a particular form of protrusions 17 of the support members 18 being used. As shown the length may be somewhat greater than the upper to lower edge dimension of the protrusions. This may enable use of the intersection members of various different forms of support members, although it may be preferable, mechanically, to make the length only a clearance fit with the upper to lower edge dimension.

The configuration of the described intersection members as having a generally tubular mounting member 19 and a base 15, of polyhedral form with the number of edge surfaces 15a corresponding to the number of engageable portions 20, enables a neat appearance of the completed ceiling to be achieved, as for example, shown in FIG. 5. That is, the base 15 effectively covers the region where the protrusion 17 engaged with the engageable portions 20. Also, as described with reference to FIG. 3K, the edge surface 13a of each support member 18 neatly engages an adjacent edge surface 15a, likewise presenting a neat finish. As evident from FIGS. 6 and 7, for example, the edge surfaces 15a of the base 15 are, when the depicted intersection member is viewed in plan, disposed at 90 degrees to an imaginary line from the axis of the intersection member through the engageable portion 20 and, when viewed from the side, each engageable portion is disposed centrally with respect to the adjacent surface 15a. Generally, the form of the base may be polyhedral, with the number of sides corresponding to the number of engageable portions 20, as mentioned. Thus, the base may be regular polygonal although, for example, corners of the polygonal form may be cut off as illustrated in FIG. 12. The latter may still present a neater appearance when viewed from the underside provided the side-to-side width of the flanges of the support members does not exceed the width of the “non-cutoff” side edge surfaces 15a where these abut the surfaces 13a of the flanges 13 although, generally, the edge surfaces 15a may be rather longer than the lengths of the surfaces 13a. Generally, too, the base 15 provides support portions 15b shown for example in FIG. 3E, one supporting each support member fitted to the intersection member, and thus arrayed in an array about the axis of the intersection member, preferably equiangularly arrayed as shown for example in FIG. 8A.

In the described arrangements, the latching between the engageable portions 20 and the support members 18 is effective to prevent inwards and outwards movement of the support members relative to the intersection members. This may effectively lock support members to the intersection members in the sense that they cannot be separated without defamation of one or more components, permanent or otherwise.

While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
