Low pry seismic fitting

Abstract

Applicant has disclosed a seismic fitting, and related method, to attach a cable to a structure (e.g., a concrete ceiling, wall or beam of a commercial building). In the preferred “apparatus” embodiment, the seismic fitting, when anchored, comprises: a base with a substantially circular footprint; a substantially circular inner channel, in the base, housing a midsection of cable (preferably wire rope); at least two cable exits in the inner channel, wherein the cable exits are chamfered to prevent and radially equidistant from one another; and a fastener (e.g., a concrete anchor), extending through the entire base, and having one end anchored in concrete; wherein opposite ends of the cable extend beyond the channel and fitting.

What is claimed is: 
     
         1 . A seismic fitting comprising:
 a. a base, of the fitting, having a substantially circular outer perimeter;   b. the base has a front and a back;   c. a substantially circular inner channel, in the base, adapted in size and shape to house a midsection of wire rope;   d. two wire rope exits from the inner channel,   e. a throughbore substantially perpendicular to, and extending through the center of, the base; and   f. wherein the throughbore is adapted in size and shape for a concrete anchor to extend though the entire throughbore.   
     
     
         2 . The seismic fitting of  claim 1  further comprising chamfered edges at the exits to prevent damage to the wire rope when the wire rope cable is under tension. 
     
     
         3 . The seismic fitting of  claim 1  wherein the concrete anchor is a wedge anchor. 
     
     
         4 . The seismic fitting of  claim 1  wherein the two exits are 180° apart in the channel. 
     
     
         5 . An apparatus comprising:
 a. a seismic fitting comprising:
 i. a base with a substantially circular footprint; 
 ii. the base has a front and a back; 
 iii. a substantially circular channel, in the base, wherein the channel houses a midsection of a cable; 
 iv. two cable exits in the inner channel, wherein the cable exits are radially spaced apart by 180° ; and 
 v. a throughbore perpendicular to, and extending through the center of, the base; 
   b. a concrete anchor, extending through the entire throughbore, and having one end anchored in concrete;   c. the concrete anchor is secured to the fitting; and   d. wherein two end portions of the cable extend beyond the cable exits and the fitting.   
     
     
         6 . The seismic fitting of  claim 5  further comprising chamfered edges at the cable exits to prevent damage to the cable when the cable is under tension. 
     
     
         7 . The seismic fitting of  claim 5  wherein the cable comprises a wire rope. 
     
     
         8 . The seismic fitting of  claim 5  wherein the concrete anchor is a wedge anchor. 
     
     
         9 . A method of securing a cable to a structure, the method comprising:
 a. anchoring a seismic fitting to a structure via an anchor extending perpendicular to the fitting and entirely through a central throughbore of the fitting with opposite ends of the anchor extending beyond the fitting;   b. wherein the seismic fitting comprises:
 i. a base with a substantially circular outer perimeter; 
 ii. the base has a front and a back; 
 iii. a substantially circular channel in the base and adjacent the perimeter; and 
 iv. at least two cable exits from the inner channel, wherein the at least two cable exits are radially equidistant from each other, and wherein the at least two cable exits are located on a centerline of the anchor; and 
   c. housing a midsection of cable, within the channel, with two end portions of the cable extending beyond the cable exits and the fitting.   
     
     
         10 . The method of  claim 9  wherein the cable comprises a wire rope. 
     
     
         11 . The method of  claim 9  wherein the at least two cable exits have chamfered edges to prevent damage to the wire rope when the wire rope is under tension. 
     
     
         12 . The method of  claim 9  wherein the anchor is a concrete wedge anchor and the structure is concrete. 
     
     
         13 . The method of  claim 9  wherein the at least two exits are radially equidistant in the channel. 
     
     
         14 . A method comprising:
 a. housing a midsection of cable within a substantially circular inner channel of a seismic fitting;
 i. wherein the channel has an open bottom; 
   b. anchoring the seismic fitting to a structure; and   c. whereby the midsection of cable is captured between the structure and the open-bottom inner channel.
