ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to a system for securing two spaced apart articles together with a length of cable, the cable containing a pair of loop forming mechanisms on opposite end portions thereof wherein only one of the mechanisms requires locking in order to secure the articles to the cable.
Broadly speaking, looped cable locking devices have long been known in the prior art. See U.S. Pat. No. 2,623,378 granted to G. D. Hauer on Dec. 30, 1952; U.S. Pat. No. 3,841,118 granted to R. W. Stone on Oct. 15, 1974; U.S. Pat. No. 3,987,653 granted to R. Lyon et al. on Oct. 26, 1976; and U.S. Pat. No. 5,070,712 granted to D. Fox on Dec. 10, 1991, to mention but a few. The Fox patent discloses a cable locking device having an elongated handle which pivots into and out of an open edged handle housing and contains registrable apertures in a free end of the handle and through end portions of the side walls of the housing opposite the end in which the handle is pivotally attached to the housing. The shackle of a pad lock can be inserted through the apertures in the housing and handle when registered to lock the handle in the housing to secure a rope loop therein. However, all of the aforementioned patents disclose systems which require a locking device on both ends of a cable in order to trap or lock cable end loops to separate articles to be fastened together. It therefore would be desirable to provide a system for joining two separated articles together with a cable containing loop forming mechanisms on opposite end portions thereof wherein only one of the mechanisms needs to be locked.
By means of my invention, these and other difficulties encountered in the prior art are substantially eliminated.
SUMMARY OF THE INVENTION
It is an object of my invention to provide an adjustable cable loop locking system for securing two spaced apart articles together with a length of cable.
If is a further object of my invention to provide such a cable loop locking system containing a first mechanism on one end portion of a cable to form a first adjustable loop and a second mechanism on an opposite end portion of the cable to form a second adjustable loop.
It is another object of my invention to provide a pair of mechanisms slidably disposed on opposite end portions of a length of cable for forming loops on opposite end portions of the cable which require the locking of only one of the mechanisms to secure a pair of spaced apart articles together with the cable.
Briefly, in accordance with my invention, I provide a system for securing a pair of spacially separated articles together which includes an elongated, flexible cable and a first mechanism slidably containing two lead-in portions of a first loop formed on a first end portion of the cable for adjusting the size of the first loop. A second mechanism is provided which slidably contains a first of two lead-in portions of a second loop formed on a second end portion of the cable for permitting adjustment in the size of the second loop. An end of the cable at an end of the second loop is fixedly secured to the second mechanism. Next, a device is provided for selectively fixing a first of the two lead-in portions of the first loop in a stationary position within the first mechanism when in an operative condition. The first of the two lead-in portions of the first loop contains a free end of the cable. A second of the two lead-in portions of the first loop is connected to the first of the two lead-in portions of the second loop to form a central portion of the cable extending between the first and second mechanisms. An elongated, flexible, hollow sheath is provided which slidably covers the central portion of the cable. The sheath is affixed on opposite end portions thereof to the first and second mechanisms such that the first and second mechanisms are spaced apart by a fixed distance as measured along the central portion of the cable.
These and other objects, features and advantages of my invention will become apparent to those skilled in the art from the following detailed description and attached drawings upon which, by way of example, only a preferred embodiment of my invention is described and illustrated.
