Abstract
Abstract A generally U-shaped conduit hanger is disclosed which is resistant to bending under the weight of conduit and provides for simplified conduit installation. The U-shaped hanger has a center portion for attachment to a support member and a pair of spaced depending legs for securing conduit and the like therebetween. The center portion has a pair of flat lateral edge surfaces which lie in a plane spaced from that of the surface therebetween, serving to rigidify the center portion against bending in the transverse direction. Apertures may also be provided in the terminal ends of the legs for receiving a clamping bolt or screw, preferably with one of the apertures having a thread formation therearound to threadedly receive said bolt or screw, and eliminating the need for a retaining nut.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
239 words
In a hanger of the type including a generally U-shaped support element having a bearing surface center portion with opening means for attachment to a support structure and the like and a pair of spaced legs having pipe receiving portions extending from opposite ends of said center portion for securing conduit and like members therebetween, the improvement comprising, in combination, said bearing surface center portion having a substantially flat first center surface area extending between said spaced legs and joined thereto, said opening means being centrally positioned with respect to said first center surface area, and a second center surface area integrally abutting said first center surface area, said second center surface area lying in a plane generally parallel to the plane of said first center surface area and spaced a distance therefrom, said second center surface area also extending between said spaced legs and joined thereto, said first and second center surface areas disposed transverse to the plane of said spaced legs whereby the distance differential between said first and second center surface area imparts an increased resistance to bending of said center portion about its lateral and transverse axes when conduit and like members are installed therein, and said depending legs having an aperture below each respective pipe receiving portion for receiving a fastener to secure conduit and the like between said legs, and one of said apertures having a thread impression to threadedly receive said fastener.
Claim 2
Dependent Claim
239 words
In a hanger of the type including a generally U-shaped support element having a bearing surface center portion with opening means for attachment to a support structure and the like and a pair of spaced legs having pipe receiving portions extending from opposite ends of said center portion for securing conduit and like members therebetween, the improvement comprising, in combination, said bearing surface center portion having a substantially flat first center surface area extending between said spaced legs and joined thereto, said opening means being centrally positioned with respect to said first center surface area, and a second center surface area integrally abutting said first center surface area, said second center surface area lying in a plane generally parallel to the plane of said first center surface area and spaced a distance therefrom, said second center surface area also extending between said spaced legs and joined thereto, said first and second center surface areas disposed transverse to the plane of said spaced legs whereby the distance differential between said first and second center surface area imparts an increased resistance to bending of said center portion about its lateral and transverse axes when conduit and like members are installed therein, and said depending legs having an aperture below each respective pipe receiving portion for receiving a fastener to secure conduit and the like between said legs, and one of said apertures having a thread impression to threadedly receive said fastener.
Claim 3
Dependent Claim
20 words
A hanger in accordance with claim 1 wherein said first center surface area is depressed below said lateral surface areas.
Claim 4
Dependent Claim
18 words
A hanger in accordance with claim 1 wherein said first surface is raised above said lateral surface areas.
Claim 5
Dependent Claim
226 words
In a hanger of unitary construction of the type including a generally U-shaped support element having a bearing surface center portion with opening means for attachment to a support structure and a pair of spaced apart legs having pipe receiving portions extending from opposite ends of said center portion for securing conduit and like members therebetween, the improvement comprising a bearing surface center portion having a multi-planar cross-section, said center portion having a substantially flat first center surface area extending between and connecting the spaced apart legs and through which said opening means extends, said first center surface area disposed transverse to the plane of said spaced apart legs, and two substantially flat second center surface areas abutting and joined to said first center surface area, said second surface areas also extending between and connecting said spaced apart legs, said second center surface areas also disposed transverse to the plane of said spaced apart legs said second center surface areas being disposed in a plane generally parallel to the plane of the first surface area, said second center surface areas spaced a distance away from said first surface area, whereby the difference in distance between said first and second center surface areas imparts an increased resistance to bending of said center portion about its lateral and transverse axes when conduit and like members are installed therein.
Claim 6

Claim 7
Dependent Claim
29 words
The conduit or the like hanger of claim 4 wherein the plane of said first center surface area is located below the plane of said second center surface areas.
Claim 8
Dependent Claim
29 words
The conduit or the like hanger of claim 4 wherein the plane of said first center surface area is located above the plane of said second center surface areas.
Claim 9
Dependent Claim
47 words
The conduit or the like hanger of claim 4 wherein each depending leg includes an aperture below each respective pipe receiving portion for receiving a fastener to secure conduit and the like between said legs, one said aperture having a thread impression to threadedly receive said fastener.
