Abstract
Abstract Cable retractor adapted to support and guide a slack portion of a cable connected between a stationary rack and a chassis which is slidable out of the rack. The cable retractor has brackets fixed to the moving chassis and to the rack, arms pivoted to each bracket and to a common pivot plate and standoffs to attach the slack portion of a cable to the arms so that a bend portion of the cable is positioned in spaced relation from the pivotal linkage between the first and second arms. The pivot plate linking the first and second arms has pivots which are suitably spaced to restrict the minimum bend radius of the slack portion of the cable.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
In a cable retractor comprising: a first end bracket for attachment to a rack; a second end bracket for attachment to a chassis which is slidable with respect to said rack; at least first and second cable supporting arms, said first arm having one end pivoted to said first end bracket, said second arm having one end pivoted to said second end bracket, and the other ends of said first and second arms attached to a common pivotal linkage; and means to attach a slack portion of a cable to said first and second arms; the improvements wherein: said first and second arms lie substantially in a first plane throughout their entire range of motion; said common pivotal linkage comprises a single plate disposed in a second plane parallel to and nearly adjacent said first plane, said plate rotatably supporting spaced first and second pivot pins to which the respective ends of said first and second arms are fixed; and said means to attach said slack portion of said cable to said arm comprises at least two standoffs attached at spaced intervals along each arm to support said slack portion in a third plane spaced from, but parallel to, said first and second planes.
Claim 2
Dependent Claim
204 words
In a cable retractor comprising: a first end bracket for attachment to a rack; a second end bracket for attachment to a chassis which is slidable with respect to said rack; at least first and second cable supporting arms, said first arm having one end pivoted to said first end bracket, said second arm having one end pivoted to said second end bracket, and the other ends of said first and second arms attached to a common pivotal linkage; and means to attach a slack portion of a cable to said first and second arms; the improvements wherein: said first and second arms lie substantially in a first plane throughout their entire range of motion; said common pivotal linkage comprises a single plate disposed in a second plane parallel to and nearly adjacent said first plane, said plate rotatably supporting spaced first and second pivot pins to which the respective ends of said first and second arms are fixed; and said means to attach said slack portion of said cable to said arm comprises at least two standoffs attached at spaced intervals along each arm to support said slack portion in a third plane spaced from, but parallel to, said first and second planes.
Claim 3
Dependent Claim
38 words
The cable retractor of claim 1, wherein said pivot pins each comprise a terminal segment of one of said first and second arms bent to form a substantially right angle with respectg to the rest of the arm.
Claim 4
Dependent Claim
45 words
The cable retractor of claim 1, wherein the pivotal connections between the end brackets and the corresponding arms comprises third and fourth pivot pins disposed perpendicular to said first plane, rotatably carried by said end member, and rigidly attached to the end of said arm.
Claim 5
Dependent Claim
226 words
In a cable retractor comprising: a first end bracket for attachment to a rack; a second end bracket for attachment to a chassis which is slidable with respect to said rack; at least first and second cable supporting arms, said first arm having one end pivoted to said first end bracket, said second arm having one end pivoted to said second end bracket, and the other ends of said first and second arms attached to a common pivotal linkage; and means to attach a slack portion of a cable to said first and second arms; the improvements wherein: said first and second arms lie substantially in a first plane throughout their entire range of motion; said common pivotal linkage comprises a single plate disposed in a second plane parallel to and nearly adjacent said first plane, said plate rotatably supporting spaced first and second pivot pins to which the respective ends of said first and second arms are fixed; and the pivotal connections between the end brackets and the corresponding arms comprise third and fourth pivot pins disposed perpendicular to said first plane, rotatably carried by said end member, and rigidly attached to the end of said arm; wherein said third and fourth pivot pins are terminal segments of each arm bent to form a substantially right angle with respect to the rest of said arm.
Claim 6
Dependent Claim
226 words
In a cable retractor comprising: a first end bracket for attachment to a rack; a second end bracket for attachment to a chassis which is slidable with respect to said rack; at least first and second cable supporting arms, said first arm having one end pivoted to said first end bracket, said second arm having one end pivoted to said second end bracket, and the other ends of said first and second arms attached to a common pivotal linkage; and means to attach a slack portion of a cable to said first and second arms; the improvements wherein: said first and second arms lie substantially in a first plane throughout their entire range of motion; said common pivotal linkage comprises a single plate disposed in a second plane parallel to and nearly adjacent said first plane, said plate rotatably supporting spaced first and second pivot pins to which the respective ends of said first and second arms are fixed; and the pivotal connections between the end brackets and the corresponding arms comprise third and fourth pivot pins disposed perpendicular to said first plane, rotatably carried by said end member, and rigidly attached to the end of said arm; wherein said third and fourth pivot pins are terminal segments of each arm bent to form a substantially right angle with respect to the rest of said arm.
