6 Claims. ((31,189-35) Q SUSPENDED CEILING our j p L. Lydarrl, Ellieott City, Mi, assignor to Eastern The present invention relatesto suspended ceiling construction and more particularly to a clip for use in such constructions. a i I In suspended ceiling constrhctions as commonlynsed,

a series of spaced parallel runners are suspended from primary ceiling members and are used to support the "acoustical tiles or other sheets or panels which make up all or a major portion of the ceiling as viewed from the room beneath. The runners are generally formed with a vertical web portion and horizontal flanges at the top and bottom, the top flanges abutting against the primary ceiling members and the bottom'flanges serving to support the acoustical tiles or other sheets or panels. The

runners may be formed as nailing bars having a vertical web and horizontal flangesat the top. i i

' Steel wire clips of various shapes have heretofore been used for attaching runners to the primary ceiling members. The present inventionis concerned with providing a novel and improved clip foruse in a construction in suspended ceiling clips must be relatively inexpensive, it

can be expected that substantial dimensional variations will occur during manufacture; but, despite such variations, the clips should perforrnsatisfactorily. Another important requirement for such clips is that .they aitord as much stability as possible to the ceiling construction.

a novel and improved ceiling suspension clip.

More particularly, it has been an object ofthe invention to provide sucha clip" whichfulfillsthe foregoing and other requirements more satisfactorily than has .beenpossible with clip designs previously use i Patented Sept. 3, .1963

a runner13 from a ceiling channel member 14. i The runner 13, which may be formed from a single strip of steel or other suitable material, has a vertical web 15, horizontal flanges 16and 17 extending laterally from the top of Web 15 at respective sides thereof and horizontal flanges .18: and 19 extending laterally from the bottom-of web 'l5 at respective sides thereof. The ceiling channel member 14 has a vertical web 20 and'horizontal

flanges

21 and 22 extending laterally from the top and bottom, respectively, of web 20 atone side thereof. -1" i J .1

Wheninstalled, the channel member 14 and the runner 13 aredisposed so that their axes forma rightangle, with the.

upper surfacesof flanges

16 and 17 abutting the undersurface of flange .22. The runner 13 is supported from and is maintained in position beneath channel member 14 by the clip of the invention.

The lower portion 12 of the clip is formed by legs 23' and 24; each of which has a free end formed by the rc-I speotive ends of the wire stock. The free end of the leg 23 contacts the undersurface of flange 16 and the leg is inclined downwardly and extends at an angle with respect to the axes of the runner '13 "and channel member 14. Similarly, the free endof the leg 24 contacts the undersur-face of flange 1,7:and the leg is inclined downwardly *and extends at an angle with respect'to the axes of the runnerfi13 and channel member 14. j The free ends of the legs- 23 and 24 preferably touch each other before installation and lie adjacent the web 15 afterinstallation.

The

legs

23 and 24 are joined to

legs

25 and 26, respectively, by

curved bends

27 and 28, respectively, which might have, for example, a A; inch radius. The

bends

27 and 28 are disposed approximately beneath the web 15 and outwardly of the free ends. of the flanges l6 and 17, respectively. The legs. 25 and 26 comprise the clipintermediate portion 11 and are disposed so as to lie substantially vertically and adjacent the outer surface of web Ztl. The

legs

25 and 26 are inclined inwardlyin a vertical plane toward the plane iof web 15. At their upper ends the

legs

25 and 26 are adjacent the upper surface of flange 21 and are separatedfrom each otherby an appreciable distance which is substantially lessthan the combined i widths of flanges 16and 17. For example,,if flanges 1d .45 A principal object of the invention has been to provide Other and further objects, featuresand advantages of i the invention will appear more fully from thefollowing description taken in connection with the appended drawing, in which:

embodying the invention; i

FIG; 2 is a side elevational view of the clip of FIG. l;

FIG. 3 is a front elevational View of the clip of FIG. 1;

. FIG. 4 is a side elevational view, partly in cross section, showing the and FIG. 5 is a cross-sectional view taken along theline I 11; and abottorn portion 1 2, each constituted by various legs formed by bending the wire stock.

a l i FIG. 1 is a top plan view of a ceiling suspension clip Asshown in FIGS. 4 and 5, the clip serves to suspend i and 17 have a combined width of inch and if the height of channel member 14 is 1%; inches, the spacing between the upper ends of legs 25 and Zdrnight be 2 inch.

The upper ends of legs 25 and 26am joined to

legs

29 and 30, respectively, by relatively

short radiuslbends

31 and 32, respectively. The

bends

31 and 32 ,might be formed, for example, with a radius of inch. The heightof the legs 25- and 26 is selected so that the inner center of the bends 31 and, 32will lie slightly above the upper surface of flange 21.

The

legs

29 and 30 are inclined outwardly with redownwardlywiht respect to the upper surface of flange .21. Thus, contact between the legs 29 and 30' and the upper surface of flange 21 will occur primarily adjacent the front edge of flange 21, i.e., the free end of. flange 21. clip of FIG. 1 installed in a ceiling systern;

The legs 29 andISli are joined to

legs

33 and 34, re-

spectively, bybends 35fand 36, respectively. Thebends Q35 and 36 are formed with a relatively lange radius, e.-g.,

inch. The legs 33' and 34 are inclined inwardly with (respect to the plane of web 1'5 and are inclined slightly downwardly with respect to the upper surface of flange 2 1. The ,legs 3 3 and 34 are joined by a bend 37 which might have for example, a radius of A; inch. i

*The downward inclinations of legs 29, 3%;33 and 34 with The horizontal spacing between the inner center of heady an h ne s rfaces of l ss zfi n 26 is slig ly greater than the width of flange 21. The

legs

29,30;

' 33 and 34and' their joining bends comprise the clip upper portign 10 and have a generally heart shape, as shown in FIG. 1. i r a To install the clipg th e runner 1,3 and channel'me'rnbet-1A are brought into position as shown in FIGS. 4 and 5. Ilhe clip is sprung on over the flanges 15 and'1'7 of the runnerand brought into contact with the channel member. Because the downward inclination of the upper portion .10 of the clip, the legs 33 and 34- and the bend 37 will not readily passove; the top flange To cause the legs 33 34and the bend 37 to pass over the top of flange 241, .a substantial force musttbe'exerted, as by pushing with thethninbson legs 25 and is while holding the channel member with the fingers. This substantial fence causes the legs 33 and 314 and the bend 37 t n1ove upwardly against the spring action of the clip material. Bending of the legs 29 and 30and of the legs 23 and Z4- against the spring action of the clip material also aids in permitting this clearance. When the inner end of bend 37 clears the edge of flange 21, the

legs

33 and 34 and the bend 371 spring downwardly so that the inner center of bend 37 lies at the

legs

29 and 30 in tight contact with the upper surface of flange 21and also the freeends of legs 23' and 2 4 in tight contact with the undersurfac'e of

flanges

16 and 17, respectively. j r i fIn constructing a complete ceiling, the runner 13 will be suspended from at least two, and generally more, parallel ceiling channel members .by the use of clips identical to that shown.

An important advantage secured by the clip of the in surface of said ceiling member, .said first pair of legs ext n in r lly inw rdl and upwa d y t am sai second pair of legsv and, when said clip is installed, extending generally in one direction along the axis of said runner, and an upper portion formed by a series of bends in'sai-d wine and being joined at each end to the upper end flange surface of said ceiling member when said clip is installed, said upper portion extending beyond the outer edge of said upper flange surface of said-ceiling member and having an area disposed. adjacent the outeredge-of said upper flange surface when said clip is installed, the combined heights of said first and second portions being substantially equal to the combined heightscf said ceiling member said runnerlflanges, the downward inclihation of said upper portion being s i iflici e nt tovrequireha substantial springing of said clip for installation thereof.
