Abstract
Abstract A tubular standoff hanger assembly which may be installed by means of the stud welding technique. A large cross section standoff member, which provides inherent rigidity due to its large diameter, is secured to a supporting surface by means of a stud which is welded to the supporting member wherein the stud includes a flange on one end thereof complementary with the inside configuration of the tubular standoff. Mating threads and wedging means are provided to lock the flange of the stud with the standoff to maintain the standoff in engagement with the supporting surface. An adjustable hanger bracket for pipe or the like is provided on the opposite end of the standoff and includes a resilient rubber block and flexible banding in one embodiment and a stirrup-and-yoke combination in another embodiment.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A rigid tubular standoff hanger assembly adapted for installation by the stud welding technique comprising: an elongate end weldable stud having one end thereof of configuration suitable for welding by the stud end welding technique to a metalic supporting member to which the hanger is to be attached and the opposite end thereof including a flange of diameter substantially in excess of the diameter of the extremities of the weld base fillet resulting from the stud welding process; an elongate hollow standoff, having a first end thereof of internal configuration complementary with said flange of the stud and adapted to pass longitudinally over the stud and engage the supporting member to which the stud is welded; and securing means cooperating between said flange and said standoff for drawing and maintaining said first end of the standoff in firm engagement with the surface of the supporting member.
Claim 2
Dependent Claim
146 words
A rigid tubular standoff hanger assembly adapted for installation by the stud welding technique comprising: an elongate end weldable stud having one end thereof of configuration suitable for welding by the stud end welding technique to a metalic supporting member to which the hanger is to be attached and the opposite end thereof including a flange of diameter substantially in excess of the diameter of the extremities of the weld base fillet resulting from the stud welding process; an elongate hollow standoff, having a first end thereof of internal configuration complementary with said flange of the stud and adapted to pass longitudinally over the stud and engage the supporting member to which the stud is welded; and securing means cooperating between said flange and said standoff for drawing and maintaining said first end of the standoff in firm engagement with the surface of the supporting member.
Claim 3
Dependent Claim
25 words
The hanger assembly of claim 1 wherein said securing means comprises mating threads on the flange of the stud and the inside of the standoff.
Claim 4
Dependent Claim
39 words
The hanger assembly of claim 1 wherein said securing means includes apertures in the wall of the standoff and a locking pin adapted to pass through said aperture and against the bottom edge of the flange of said stud.
Claim 5
Dependent Claim
27 words
The hanger assembly of claim 3 wherein the locking pin is tapered and draws the standoff against the supporting member when the pin is driven into place.
Claim 6
Dependent Claim
75 words
The hanger assembly of claim 1 further including a second stud having a first end thereof suitable for stud welding to the article to be supported and the opposite end thereof including a substantially enlarged flange portion; wherein the opposite end of the standoff member is of configuration complementary with the flange of the second stud; and including means for securing the flange of the second stud and the standoff member one of the other.
Claim 7
Dependent Claim
68 words
The hanger assembly of claim 5 especially adapted for supporting pipe which further includes: a mounting base including a transverse aperture therein and which is stud welded to said first end of the second stud, a semiresilient snubbing block disposed between the mounting base and the pipe being supported, and a flexible unpreformed band passing through said aperture and around said pipe to secure the pipe in place.
Claim 8
Dependent Claim
124 words
The hanger assembly of claim 1 especially adapted for supporting a pipe further including; a pipe stirrup including two hinged members adapted for clamping disposition around the pipe to be supported and terminating in two parallel upper ends each having apertures therein; a yoke either end of which is tapered passing through and wedging in said apertures; a second elongate stud having one end thereof stud welded to the central portion of said yoke and including a flange on the opposite end thereof; the opposite end of said standoff being of complementary configuration with said flange of said second stud; and means cooperating with said flange of the second stud and said standoff for securing the flange and standoff rigidly one to the other.
