Haertel & Co., Melrose Park, Ill., a corporation of Illinois Filed Sept. 7, 196%, Ser. No. 54,506 21 (Jlaims. (Cl. 189-416) This invention relates to a ceiling suspension system using a double locking clip for securing the longitudinal support members and transverse support members in an interlocking engagement. More particularly, this invention relates to a ceiling suspension system wherein the transverse support members are supported upon a longitudinal support member and are interlockingly engaged therewith and with each other through the use of a novel double locking clip.

This invention provides an improved support system for suspended ceilings of the acoustic tile type or the like. The support system of the present invention combines longitudinal support members which are hung or otherwise secured preferably to the overhead construction by means of Wires or the like and transverse support members which are supported upon and interlockingly engaged with the longitudinal support member and with each other through the medium of a novel double locking clip as is described hereinafter. The double locking detachable clip of the present invention is slidably positioned on an extended end portion of a transverse support member and has a spring nose that enters a slot in the web of the longitudinal support member, the respective clips on each of the transverse support members on opposite sides of the web of the longitudinal support member being inverted vertically to enter one of the aligned slots in the web of the longitudinal support member so that the transverse support members on the opposite sides of the longitudinal support member will be in alignment and so that the clips on each of the transverse support members will be in interlocking engagement with the transverse member on the opposite side of the web.

The interlocking engagement of the clip on transverse support member forces the nose of the clip to expand and the tongues thereof to engage the opposite side of the web on each side of a slot to cause a double locking action by locking each transverse support member to its oppositely positioned member with respect to the web of the longitudinal support member and also to lock each transverse support member to the longitudinal support member on which it is supported.

The clips are releasable from the transverse supports to permit interchange from an upper position on a transverse support member to a lower position on a transverse support member. This feature of interchangeability of the clip permits the use of a standard clip in both upright and inverted positions on the transverse support member, thereby effecting an economic benefit in both standardization of manufacture and in the use of only one type of clip at the job site.

An object of the present invention is to provide a ceiling suspension support system whereby the under surfaces of the longitudinal support members and transverse support members are coplanar.

A second object of the present invention is to provide a ceiling suspension system wherein through the use of a novel double locking clip, a substantially unitary suspension system is provided.

Other objects and advantages of the present invention will become apparent to those skilled in the art from the following description of the invention taken in conjunction with the accompanying drawings in which:

FIG. 12 is a fragmentary sectional view taken through the line 1212 of FIG. 11 showing the double locking clip of the present invention engaging the longitudinal support member and each of the respective transverse members engaging the opposite transverse support member aligned therewith on each side of the longitudinal support.

Referring to the drawings in detail and describing first the novel suspension ceiling support system of the present invention as shown in FIG. 1, there is shown two longitudinal support members 10 being supported from the overhead construction by wires 11. A plurality of transverse support members 12 are supported on and locked to the longitudinal supports it). A plurality of acoustical tile members 13 are shown supported on the longitudinal supports it? and transverse supports 12. As seen in the drawing FIG. 1, the present invention permits the under surfaces of the flanged portions of the longitudinal support members it) and the transverse support members 12. to be coplanar and to give the effect of a substantially unitary suspension support system.

The novel clip 14 of the present invention as show in FlGS. 2, 3 and 4, has a body section 15 having portions 16 and 1'7 thereof spaced apart and bent approXimately from the plane of the body, as can best be seen in FIG. 3, for slidable engagement with the extended portion of the transverse support members. The bent over portions to and 17 are shown substantially parallel with the body 15. The portion 17 extends longitudinally forwardly from the body portion 15 to be parallel with the vertically reduced extended section 18 of the body 15 as shown in FIG. 4. The spring nose terminal ends of the forwardly extended sections 17 and 13 have, in order of distances from the body 15, outwardly forwardly flaring portions 19 and 20 and inwardly forwardly flaring portions 21 and 22 and outwardly forwardly flaring lips 23 and 24 all of which can best be seen in FIG. 4. The spring nose terminal end of the clip 14 is also provided with tongue members 25 and 26 which flare outwardly and rearwardly substantially in a plane with the inwardly flaring portions 21 and 22, which tongue members engage the opposite sides of the longitudinal support members after passing through slots provided therein. The clip 14 also has on the body portion 15 an inwardly biased tongue member 27 which cooperates with a hole in the ends of the extended web of the members 12 for retaining the clip positioned thereon, which cooperation will be more fully described hereinafter.

The transverse support member 12 shown in FIG. 5 is shown in the form of a T-bea-m having a laminated vertical web 29 as can best be seen in FIG. 6, and lateral coplanar horizontal flanges St! on opposite sides thereof. The web 29 of the transverse support member 12 is here shown formed by the folded laminations 33.
