Definitions
- the present invention relates to a grid member, commonly referred to as a runner or tee, for use in a suspended ceiling system for supporting ceiling tiles.
- a typical grid tee construction includes a metal strip formed into an upper strengthening bulb or bead, a vertical, downwardly-extending double web, and lower, oppositely-extending flanges. The exposed or lower surface of the flanges is not continuous That is, there is a transition visible between the flanges where they extend from their respective vertically-extending web member.
- This transition is often considered to be aesthetically unpleasing, and a cap member is applied to the diverging flanges to cover the transition and provide a more finished appearance to the grid tee, as well as to provide additional resistance to spreading of the flanges.
- the addition of the cap member adds to the cost of the grid tee both due to additional material costs and the required roll-forming steps for applying the cap member, and also increases the weight of the grid tee.
- a runner or tee is roll-formed from a single strip of sheet metal so as to have a generally symmetrical appearance about a vertical center line, with a double vertical web and a double-thickness flange for supporting ceiling tiles.
- the bottom surface of the flange is continuous across its exposed surface. That is, there is no visible juncture of the opposed flanges with the double web when viewed from below, thus providing an aesthetically more-pleasing appearance.
- FIG. 1 is a sectional view of a ceiling grid member according to the present invention in which the reinforcing bead includes a fin extending upwardly therefrom.

Abstract
A runner for a suspended ceiling grid is roll-formed from a single strip of sheet metal so as to have a generally symmetrical appearance about a vertical center line, with a double vertical web and a double-thickness flange for supporting ceiling tiles. The bottom surface of the flange is continuous across its exposed surface, so that there is no visible juncture of the opposed flanges with the double web when viewed from below, thus providing an aesthetically more-pleasing appearance
Description
- The present application claims the benefit of the filing date of U.S. Provisional Application, Ser. No. 60/751,866, filed Dec. 20, 2005, which is incorporated herein by reference.
- The present invention relates to a grid member, commonly referred to as a runner or tee, for use in a suspended ceiling system for supporting ceiling tiles. A typical grid tee construction includes a metal strip formed into an upper strengthening bulb or bead, a vertical, downwardly-extending double web, and lower, oppositely-extending flanges. The exposed or lower surface of the flanges is not continuous That is, there is a transition visible between the flanges where they extend from their respective vertically-extending web member. This transition is often considered to be aesthetically unpleasing, and a cap member is applied to the diverging flanges to cover the transition and provide a more finished appearance to the grid tee, as well as to provide additional resistance to spreading of the flanges. As can be readily appreciated, the addition of the cap member adds to the cost of the grid tee both due to additional material costs and the required roll-forming steps for applying the cap member, and also increases the weight of the grid tee.
- Accordingly, it is an object of the present invention to provide a grid tee for a suspended ceiling system in which the tee is made from a single strip of sheet metal but does not require a cap member for aesthetic or structural reasons.
- According to the present invention, a runner or tee is roll-formed from a single strip of sheet metal so as to have a generally symmetrical appearance about a vertical center line, with a double vertical web and a double-thickness flange for supporting ceiling tiles. The bottom surface of the flange is continuous across its exposed surface. That is, there is no visible juncture of the opposed flanges with the double web when viewed from below, thus providing an aesthetically more-pleasing appearance.
-
FIG. 1 is a sectional view of a ceiling grid member according to the present invention in which the reinforcing bead includes a fin extending upwardly therefrom. -
FIG. 2 is a first alternate embodiment of the ceiling grid member ofFIG. 1 in which the fin is formed with a lock seam. -
FIGS. 3-7 are further alternative embodiments of the grid member ofFIG. 2 that differ in the configuration of the lock seam formed in the fin. -
FIGS. 8 and 9 are alternate embodiments of the ceiling grid member according to the present invention in which the upper portion of the vertical web is configured with slots. -
FIGS. 10-13 are alternate embodiments of a ceiling grid member according to the present invention in which the strengthening bead is formed so as to give the cross-section a configuration more like a traditional I-beam -
FIGS. 14 and 14 A are alternate embodiments of a grid member according to the present invention in which the grid member does not have a strengthening bulb at the upper end thereof. -
FIGS. 15 and 15 A are similar toFIGS. 14 and 14 A except that the grid members include a cap member of affixed to the flanges. -
FIGS. 16 and 16 A are alternate embodiments of the grid members ofFIGS. 14 and 14 A in which the flanges are configured to form a bolt slot. - Grid members for suspended ceilings are well-known in the art, as exemplified by the runners or tees shown in U.S. Pat. Nos. 4,525,973, 4,549,383, 4,601,153, 4,677,802 and 4,785,595, all incorporated herein by reference and all having the same assignee as the present invention. Such runners or tees are roll-formed from an elongated strip of sheet metal into a configuration having a strengthening bead or bulb at the upper end, a web extending vertically downward from the bead, and opposed flanges at the lower end of the web.
- With reference to
FIGS. 1-7 , profiles of grid members, according to the present invention, generally designated 10, are seen. Thesegrid members 10 have the same structural features as the typical runners or tees, namely, an intermediatevertical web 12 having abead 14 at its upper end and opposedflanges - In keeping with the invention, the
grid members 10 are roll-formed from a single elongated strip of sheet metal such that the opposed side edges of the strip are located at thereinforcing bead 14. This results in thevertical web 12 of therunner 10 having a double thickness and the lower surface of theflanges - Turning specifically to
FIGS. 1-7 , the grid member includes strengthening bead orbulb 14 that preferably, but not necessarily, includes a generally vertically-extending “fin” 20 to provide increased beam height and, thus, increased resistance to bending. Such a reinforcing fin is discussed in copending application Ser. No. 11/499,035, filed Aug. 4, 2006, which is incorporated herein by reference. The fin configuration permits the runner to be formed of thinner material than prior art runners not having such a fin without compromising the beam strength of the runner. This results in a runner that is more economical to manufacture (because less material is required), is easier to handle (particularly in bulk or carton quantities to each runner is lighter in weight), and is easier to cut. - With specific reference to the embodiments of
FIGS. 2-7 , thefin 20 includes a lock seam in which at least a portion of thefin 20 is bent back on itself. The lock seam provides increased resistance to torsion and buckling, and thus increased ultimate load resistance. Forming the lock seam “work hardens” the material in the local area, thus enhancing the overall mechanical properties of the runner. With reference toFIG. 2 , the lock seam has a triple thickness of sheet material, with a first edge of the sheet metal strip from which the grid member is formed extending beyond the second edge and the first edge being bent over the second edge. With reference toFIG. 3 , the lock seam has a quadruple thickness, with the first edge and second edge of the sheet metal strip meeting and both edges being bent back over the second edge. The lock seam of theFIG. 4 embodiment also has a quadruple thickness. However, the second edge is first bent downwardly toward the center of the bead and then the first edge is bent over the top of the fold in the second edge. The embodiments ofFIGS. 5-7 are similar to that ofFIG. 4 , except that the second edge extends into the interior of the bead (FIG. 5 ); or the second edge lies against the interior of the bead (FIG. 6 ); or the second edge lies against the interior of the bead and the first edge lies against the exterior of the bead (FIG. 7 ). - With reference to embodiment of
FIG. 14 , a further alternative for atee 14 according to the present invention is shown. This alternative does not include a strengthening bulb or bead. As shown inFIG. 14A , if the tee has no bulb or lock seam at the upper end of the web, a strengtheningstitch 22 in the vertical web may be desirable to maintain the structural integrity of the tee. Such a stitch ormechanical interlock 22 is well known in the art, as shown by, e.g., U.S. Pat. Nos. 5,577,313, 5,979,055 and 6,047,511, and also may be used in the embodiments ofFIGS. 1-7 . Alternatively, the vertical webs can be welded or otherwise fastened to each other (as by an adhesive). - While not required, a
cap 24 can be applied to the flanges for additional strength or for aesthetic reasons, as seen in embodiments ofFIGS. 15 and 15 A, which otherwise are identical to the embodiments ofFIGS. 14 and 14 A. In a further alternative, instead of an opposed flanges for supporting ridges of ceiling tiles, the lower portion of the runner can be provided with abolt slot profile 26, as seen in the embodiment ofFIGS. 12 and 12 A. Previous designs having a bolt slot required the profile to be roll formed from pre-painted strip with finish colors on both sides of the strip. The embodiments ofFIGS. 16 and 16 A require the strip to be painted on one side only, thus providing a cost reduction. -
Alternate bulb configurations 14 are seen in the embodiments ofFIGS. 8 and 9 . The open lower portions of the bulb permit the use of accessory clips. Specifically, the lower horizontal flange of the bulbs do not extend to the vertical web, creating a slot or agap 28 that allows the lower end of a clip to be received and retained by the bulb, or otherwise facilitates suspension of the tee. The embodiments ofFIGS. 8 and 9 also utilize astitch 22 through the upper portion of thevertical web 12 to help maintain profile geometry and strength. Thestitch 22 is concealed, thus resulting in improved aesthetics of the profile. -
FIGS. 10-13 show further embodiments ofgrid members 10 according to the present invention in which the strengtheningbead 14 is formed to have a generally flat configuration that lies in a plane that is substantially parallel to the plane defined by theflanges FIGS. 10-13 being easier to roll form. Further, the distance that the material defining the bead is spaced from the flanges is maximized, thus maximizing the load rating for the grid members while utilizing the least amount of material. Each of the embodiments ofFIGS. 10-13 also includes astitch 22 in theirvertical webs 12 to help maintain the integrity of the grid geometry. - Turning specifically to
FIG. 10 , the strengtheningbead 14 is formed by bending the edges of the strip so as to be generally perpendicular to the vertical web and then bending the edge downwardly back on itself The strengtheningbead 14 in the embodiment ofFIG. 11 is formed similarly, except that the edges are bent upwardly back on themselves, and the edges meet along the vertical center line of the grid member. The strengtheningbead 14 in the embodiment ofFIG. 12 is similar to that ofFIG. 10 , except the edges are bent back on themselves twice, resulting in the strengtheningbead 14 to have a triple thickness of sheet material. The strengtheningbead 14 in the embodiment ofFIG. 13 is similar to that ofFIG. 12 , except that the edges are bent upwardly. - Thus, a single strip ceiling grid member has been provided that meets the objects of the present invention. While the invention has been described in terms of certain specific embodiments, there is no intent to limit the invention to the same. Instead, the invention is defined by the following claims.
