Abstract

An adjustable coupler is on opposite ends of a cable for securing a pre-established tension in the cable. Such pre-adjusted tension is effected by conventional tensioning mechanism applied between a pair of nuts threaded on opposite ends of the cable. The coupler itself involves an elongated turnable coupling body which spans ends of the cable and in which a first nut is threaded in one of its ends and a second nut is threaded in its other end. The first nut is engageable with abutment means on one of the cable ends inside of the coupling unit. The second nut is threaded on both the cable and in the coupling body and is secured to the coupling body such that turning of the coupling body results in its movement about the axis of the cable to cause the first nut to engage the abutment means at which time the coupler is then adjusted to maintain the pre-adjusted tension. Thereafter the tensioning mechanism may be removed.

Claims

1. A coupling mechanism for securing a preadjusted tension in a cable having a first cable end and a second cable end, the combination including an elongated coupling body having a first end portion and a second end portion within which said first and said second cable ends respectively extend, a first abutment means on said first of said cable ends, said first abutment means and said first end portion of said coupling body being spaced such that said first abutment means may freely move axially within said coupling body, means defining a screw threaded connection between said second cable end and said second coupling portion such that turning of said coupling body about its axis results in axial movement of said coupling body on said second cable end, a second abutment means on said first coupling end portion for engagement with said first abutment means on said first cable end, said first abutment means being spaced between said screw threaded connection and said second abutment means, said first and said second abutment means being moved into engagement by turning said coupling body about its axis to turn said coupling body on said second cable end and to move said second abutment on said first coupling portion towards said first abutment means during which said first abutment means is free to move in said coupling body, said first abutment including an element threaded on said first cable end, and said second abutment means including an element threaded within said first coupling end portion, and means for securing said second abutment means on said coupling body to prevent relative movement therebetween.
