1 Claim. (Cl. 248-228) This invention relates to suspension means, and, more specifically, the invention pertains to means espec ally designed to suspend fixtures or devices from a ceiling framework.
One of the primary objects of this invention is to provide suspension means supported on a ceiling framework for suspending electric outlet boxes, lighting fixtures, and other articles therefrom.
Another object of this invention is to provide suspension means for support on the joists of a ceiling framework for supporting electric outlet boxes, lighting fixtures, and other articles, the means comprising a clip for connection with a ceiling supported channel member.
A further object of this invention is to provide a clip together with means for suspending electrical fixtures and other articles therefrom, the clip being readily connected and disconnected from a ceiling supported channel member.
Still another object of this invention is to provide a suspension device of the type described which requires no tools for installation at the desired position and which does not require the use of welding, rivets, nuts and bolts and/or other similar securing means for connecting the clip to the above mentioned channel member.
This invention contemplates, as a still further object thereof, the provision of suspension means of the type generally referred to supra, the suspension means being non-complex in construction and assembly, inexpensive to manufacture, and durable in use.
Other and further objects and advantages of the instant invention will become more evident from a con- .sideration of the following specification when read in conjunction with the annexed drawings, in which:
Figure 1 is a perspective view of the clip type suspension means constructed in accordance with this invention and illustrates its connection with a channel member for efiecting suspension of a fluorescent light;
Figure 2 is an enlarged perspective view of the clip, per se;
Figure 3 is a detail cross-sectional view taken substantially on the vertical plane of line 3--3 of Figure 1, looking in the direction of the arrows;
Figure 4 is a fragmentary detail cross-sectional view taken substantially on the vertical plane of line 4-4 of Figure 3, looking in the direction of the arrows;
Figure 5 is a detail cross-sectional view of the clip and its associated channel member, this figure illustrating another application of the suspension means wherein the same is utilized to draw the reflector of an electric light fixture flush against the ceiling;
Figure 6 illustrates the suspension means together with a lock nut adapter; and,
Figure 7 illustrates the suspension means for suspending an electric outlet box.
Referring now more specifically to the drawings,reference numeral 10 designates a conventional acoustic type ceiling supported from a plurality of conventional channel-shaped joists 12. Thejoists 12 include upper flanges 2,9532% Patented Dec. 6, 1960 14 across which rest aflange 16 which projects from the lower end of a vertically disposedbight portion 20 of achannel member 18, the latter also including anotherflange 22 which is on the same side of thebight portion 20 as theflange 16 and projects from the upper end of thebight portion 20.
Theclip members 24 may be mounted on the channel shapedmember 18 either before or after the channelshaped member is placed on thejoists 12. To connect theclip members 24 to the channel-shaped member 18, thelip extension 40 is passed over theflange 16 with the latter extending in a plane substantially bisecting the angle formed at the junction of theflange 28 with theflange 38. Theclip 24 is then manipulated to move theflange 28 towards theflange 16 and substantially simultaneously therewith thebight 30 is pivoted towards thebight 20. With the two bight portions, 20 and 30, respectively, superimposed one against the other, theclip 24 may be released to permit theflange 26 to engage and rest on theflange 22 and thelip extension 40 to rest on theflange 16.
With theclip 24 mounted on the U-shaped channel member and the latter extending across and being supported by a pair ofadjacent joists 12 the suspension device is ready for utilization. v
A conventional overhead lighting fixture is generally designated by reference numeral 42 (see Figure 1). Thelighting fixture 42 is designed to be suspended adjacent theceiling 10 by means of a pair of longitudinally spacedsuspension rods 44, each having a necked down upper end portion 46 (see Figure 3) forming ashoulder 48 and which terminates in a threaded end 50. A pair of inverted substantially frusto-conical shields are indicated at 52 and each includes aside wall 54 and anend wall 56 extending across the smaller end thereof and being-provided with acentral aperture 58. The upper reduced or necked downportions 46 of thesuspension rods 44 are passed through theapertures 58 until theend walls 56 engage against theshoulders 48. The necked downportions 46 are then extended throughsuitable openings 60 formed in theceiling 10 so that the threaded ends 50 thereof thread into theapertures 32 thus effecting connection with theclip 24. As the upper threaded ends 50 of thesuspension rods 44 continue to move upwardly relative to theflange 28 they engage against theflange 16 and further rotation of therods 44 causes theclip 24 to move downwardly relative to the channel shapedmember 18 until theflange 26 engages theflange 22 and theflange 16 engages under thelip 40 to ettect a clamping action between the engaged flanges. It will be understood, of course, that the above described threaded engagement takes place only after the rods'44' have been elevated-to engage the base of the shield-52 against the ceiling- 10.;
Figure 5' illustrates another adaptation of this invention wherein reference numeral 100 designates an-electric light reflector havingopposed side walls top wall 108 adapted to lie flush with-theceiling 10. Thetop wall 108 is provided with one or more centrally locatedapertures 110 which are aligned with oneor more of theapertures 60 formed in theceiling 10. In this instance, one or more threaded bo1ts112 are substituted for thesuspension rods 44, the bolts 112-having a diameter less than the diameter of thesuspension rods 44. The upper ends of thebolts 112 are threaded into the threaded aperture 34' for engagement against theflange 16 in the same manner as described above. In this case, however, the lower threaded end of thebolt 112 is extended through the'aperture 60 and theaperture 110 formed in thewall 108. A lock washer 114 and not 116 are passed over the threaded lower end of thebolt 112, and thenut 116 is then tightened to draw thetop wall 108 of the reflector 100 against theceiling 10.
Figure 6 illustrates another embodiment of this invention wherein the suspension rod or rods 200 having threadedupper ends 202 have an outside diameter greater than the inside diameter of theaperture 34 and less than the inside diameter of theaperture 32. In this case, the upper threadedend 202 is passed upwardly through theaperture 32 and is threaded through asuitable lock nut 204 having an outside dimension greater than the diameter of theaperture 32. The not 204 rests on theflange 28 and the rod 200 is threaded therethrough to contact theflange 16 and to force it into engagement with thelip 40 and simultaneously therewith to force theflange 22 into engagement with theflange 26, in the manner described above.
Figure 7 illustrates another embodiment of this invention wherein a threadednipple 300 may be engaged in either of theapertures end wall 302 of anelectric outlet box 304. As is seen in this figure, thebox 304 extends upwardly through an enlargedopening 306 formed in theceiling 10 so that theWall 302 of thebox 304 may be drawn tightly against theflange 16 by means of a nut 308 threadedly engaged on the lower end of thenipple 300;
Having described and illustrated several embodiments of this invention it is to be understood that the same are offered merely by way of example, and that the present invention is to be limited only by the scope of the appended claim.
What is claimed is:
