7 Claims. (Cl. 248-228) This invention relates to supports and, more particularly, to supports for suspending pipes, ducts, and other fixtures and the like from I-beams, channels, pipes, and other types of beams.

Up until the present time, no simple, efficient, and completely satisfactory support has been provided for suspending various fixtures from beams. Many such supports are diflicult and time consuming to install. Others are not positive in operation.

It is, accordingly, an object of this invention to overcome the disadvantages in prior supports and, more particularly, it is an object to provide a support which is simple in construction, economical to manufacture, and simple and efficient to use.

Another object of this invention is to provide a support which can easily be installed and readily released.

A further object of the invention is to provide an improved support for suspending objects from beams and the like. 7

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Fig. 1 is an end view of a supporting device according to the invention;

Fig. 2 is, a side view of the device shown in Fig. 1;

Fig. 3 is an end view of another embodiment of the invention;

Fig. 4 is a side view of the embodiment of the invention shown in Fig. 3;

Fig. 5 is a view of another embodiment of the invention showing the releasing rod in released position;

Fig. 6 is a view of the embodiment of the invention shown in Fig. 5 showing the releasing rod in another stage of the attaching operation;

Fig. 7 is a view of the embodiment of the invention shown in Fig. 6 showing the releasing rod in completed clamped relation;

Fig. 8 is another embodiment of the invention;

Fig. 9 is still another embodiment of the invention; and

Fig. 10 is another embodiment of the invention.

Now with more specific reference to the drawings, Figs. 1 and 2 show an I-beam 10 which has flanges 11 and 12. The Lbeam 10 is of the standard type and is shown for purposes of illustration only and constitutes no part of the invention.

A clamp 14 is made up of two

interchangeable bracket members

15 and 16. Each

bracket

15 and 16 has a straight portion 17 bent outwardly at 18 to form an outwardly extending portion 19 and then bent back on itself at 20 to form an overlying portion 21 spaced from the outwardly extending portion 19 and overlying the flanges 11 and 12 of the I-beam 10. A hole 22 is formed in each bracket 15 and 1-6 and a support rod 23 has a hook 24 forming the upper end thereof. The hook 24 is made by bending the rod 23 back on itself with a distal end 25 spaced from a main body portion 26 a distance approximately equal to the thickness of the two straight portions 17. The hook 24 is bent inwardly at 27 at the tip thereof to form the hook portions of the rod 23 to engage the two straight portions 17 on opposite sides.

For purposes of illustration, a nut 28 is shown thread ably engaging the support rod 23 at 29; however, any other type of fastening means could be used to suit the particular application.

In the embodiment of the invention shown in Figs. 3

. and 4, a support for use with a channel is shown with a channel 110 having flanges 1-11 and 112 with a clamp 114 similar to the support shown in Fig. l but adapted for use with the channel 110. The clamp 114 has a bracket member 115 similar to the

bracket members

15 and 16 shown in Figs. 1 and 2. An end 119 of the bracket member 115 is bent back on itself at 120 to form an overlying portion 121. A left hand bracket 130, however, is extended straight up from a hole 122 to lie along a web 131 of the channel 110 and is bent inward-1y at a right angle at 132 to form a leg 133 which overlies the flange 111. A support rod 123 is identical to the support rod 23 in Fig. land operates in a similar manner.

In the embodiment of the invention shown in Figs. 5, *6, and 7, a'support clamp 214 is shown which is similar in operating principle to that shown in Figs. 1 and 2;

' however, brackets 215 are especially adapted for use with a pipe or round beam. The brackets 215 each have a straight portion 217 with a support rod 223 which operates in a hole 222. Therod 223 is bent back on itself and terminates at a distal end 224. The straight portions 217 are bent outwardly to form outwardly extending portions 219 and bent around to form overlying portions 221 to overlie a pipe or round beam.

The embodiment of the invention shown in Fig. 8 is similar to that shown in Figs. 5, 6, and 7; however, the upper end of overlying portions 321 have interengaging hook members 340 and'341 formed thereon to lock a bracket 315 above a round beam. A hook member 323 engages a hole in a straight portion 314 of the bracket 315. To release the support shown in Fig. 8, the member 323 is rotated in the manner shown in Fig. 6 for that embodiment to a position show in Fig. 5. Then upon release, the bracket members 315 can be separated. The hook members 3 40 and 341 are formed by removing the material from the ends of each of the overlying members 321 to form an interfitting dovetail type connection.

In the embodiment of the invention shown in Fig. 9, a bracket 415 is shown similar to that shown in Fig. 8; however, the ends of legs 421 are bent back on themselves, one inwardly at 450 and one outwardly at 451 to form two

mating hooks

452 and 453. The ends of the

hooks

452 and 453 interlock with each other and therefore form a locking portion to lock the ends together. A support rod 433 engages .a hole in a straight portion 414 of the bracket 415.

In the embodiment of the invention shown in Fig. 10, a support 515 is shown similar to that in Figs. 8 and 9; however, the ends of legs 521 are notched at 556 and 557, respectively, to interfit and a lug 558 is attached to the legs 521 and conforms in area thereto. A lug 560 is attached to the end of the left leg 521, the lug 560 extend ing outwardly and lying behind the lug 558, thereby forming a locking joint. The support 515 has a straight portion 514 with a hole therein which receives a hook portion 523.

It will be noted in all embodiments of the invention that the hole 22 must be set toone side of the bracket so that the distance from an outer edge 540 of the hole 22 to the edge of the leg adjacent thereto is slightlyless than the distance of the end 25 and the body portion 26 of the hook 24. so that the hook 24 can. be swung around for releasing as shown in Figs. 5, 6, and 7. The end of the hook 24, must be turned in slightly at 27 in order to hold the two

bracket portions

15 and 16 snugly together.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents Without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
