Abstract

The present invention is a clip used in the construction of suspended ceiling grid systems for the hanging of drywall or other panels. The clip provides a versatile means of joining two suspended grid beams at various points of transition between two grid beams, such as a transition in the ceiling surface, thus eliminating the need for a different means of joining in each situation.

Claims

1. A clip for suspension ceiling grid beams comprising:

a first clip piece having a first side;

a second clip piece having a first side, said second clip piece being substantially co-linear with and having an integral connection to said first clip piece;

a substantially integral retainer member formed along said first and second clip pieces extending co-linearly along a common edge of said first and second clip pieces and projecting away from the first sides of said first and second clip pieces, said retainer member having a notch spanning said integral connection; and

a weakened zone generally at said integral connection between said first and second clip pieces and non-parallel to said common edge thereof, said clip being bendable at said zone.

2. The clip as recited in claim 1, wherein said retainer member is a channel formed along said edge.

3. The clip as recited in claim 1, wherein said first clip piece has an end extension flange extending generally parallel to said common edge.

4. The clip as recited in claim 3, wherein said extension flange has holes therethrough.

5. The clip as recited in claim 3, wherein said second clip piece has an end extension flange extending generally parallel to said common edge.

6. The clip as recited in claim 5, wherein said extension flanges have holes therethrough.

7. The clip as recited in claim 1, wherein said first and second clip pieces having raised bosses thereon, said bosses projecting outwardly from the first sides of said first and second clip pieces.

8. The clip as recited in claim 7, wherein said raised bosses having holes therethrough.

9. The clip as recited in claim 1, wherein said clip is formed out of metal.

10. The clip as recited in claim 7, wherein said raised bosses are stamped to project from said clip.

11. The clip as recited in claim 1, wherein said first and second clip pieces are of equal portions.

12. The clip as recited in claim 1, wherein said retainer member comprises bendable tabs formed along said edge.

13. A system of joined grid beams comprising:

an intersection of at least two grid beams, each said grid beam having two ends, a base portion having a grid face and a back surface, a web portion having two sides, a top portion, and extending from the base portion;

a clip having a first clip piece, a second clip piece co-linearly formed and having an integral connection with said first clip piece, and a retainer member formed along an edge of said clip pieces, said retainer member having a notch positioned generally at said integral connection, said top portion of each of said at least two grid beams retained by the retainer member, said first clip piece being bendable and severable along a weakened zone generally at the integral connection of said clip pieces; and

means for securing said first and second clip pieces to said web portions of said at least two grid beams;

wherein said clip joins said at least two grid beams.

14. The system of joined grid beams as recited in claim 13, wherein the intersection of said at least two grid beams comprises the meeting of the ends of the at least two grid beams, where the grid beams are co-linear.

15. A system of joined grid beams comprising:

an intersection of at least two grid beams, each said grid beam having two ends, a base portion having a grid face and a back surface, a web portion having two sides, a top portion, and extending from the base portion;

wherein the intersection of said at least two grid beams comprises the meeting of the ends of the at least two grid beams at an angle;

a clip having a first clip piece, a second clip piece bendably and severable formed with said first clip piece, and a retainer member formed along an edge of said clip pieces, said top portion of each of said at least two grid beams retained by the retainer member; and

means for securing said first and second clip pieces to said web portions of said at least two grid beams;

wherein said clip is severed into said second clip piece and said first clip piece and said clip pieces are pivotally joined to connect said at least two grid beams.

16. The system of joined grid beams as recited in claim 15, wherein the web portions of said intersecting grid beams are co-planar.

17. The system of joined grid beams as recited in claim 15, wherein at least one of said two grid beams is curved for at least a part of its length.

18. The system of joined grid beams as recited in claim 15, wherein the intersection of said at least two grid beams is curved for at least a part of its length.

19. The system of joined grid beams as recited in claim 18, wherein the angle is a right angle.

20. A method of connecting two suspension grid beams comprising the steps of:

retaining a first suspension grid beam at a clip at a first portion of a substantially integral and co-linear retainer member of said clip, whereby said first portion of said substantially integral and co-linear retainer member is in contact with a top portion of said first suspension grid beam

securing said first suspension grid beam to said clip;

retaining a second suspension grid beam at a second portion of said substantially integral and co-linear retainer member of said clip, whereby said second portion of said substantially integral and co-linear retainer member is in contact with a top portion of said second suspension grid beam;

said first and second portions of said substantially integral and co-linear retainer member being defined by a centralized notch; and

securing said second suspension grid beam to said clip.

21. A method of connecting two suspension grid beams comprising the steps of:

severing an integral clip at a zone formed non-parallel to an edge of two integrally connected clip pieces, thereby creating separate first and second clip pieces;

pivotally attaching said first and second clip pieces together by mechanically securing extension flanges of said first and second clip pieces, said attachment thereby allowing said first and second clip pieces to pivot with respect to each other;

retaining a first suspension grid beam at a retainer member portion of said first clip piece;

mechanically securing said first suspension grid beam to said first clip piece;

retaining a second suspension grid beam at a retainer member of said second clip piece; and

mechanically securing said second suspension grid beam to said second clip piece.

22. A method of connecting two suspension grid beams comprising the steps of:

removing at least a portion of a spine of a substantially integral and co-linear retainer member of an integral clip;

bending said integral clip at a weakened zone formed non-parallel to an edge of a first clip piece and an integrally connected second clip piece, thereby forming an angle between said clip pieces of said integral clip;

retaining a first suspension grid beam at said first clip piece at a first portion of said retainer member, whereby said first portion of said retainer member is in contact with a top portion of said first suspension grid beam;

securing said first suspension grid beam to said first clip piece;

retaining a second suspension grid beam at said second clip piece at a second portion of said retainer member, whereby said second portion of said retainer member is in contact with a top portion of said second suspension grid beam; and

securing said second suspension grid beam to said second clip piece.
