Abstract:
1. A cable guide, comprising: a rotatable cage having front and back ends, a rotation axis passing through the front and back ends of the cage, and a cable channel along the cage rotation axis; a slot dividing the front of the cage, the slot having first and second opposed side surfaces; two pulley wheels rotatably mounted in the slot on opposite sides of the cage axis, each wheel having a rotation axis, the wheel axes substantially parallel to each other defining a plane normal to the cage axis, each wheel having a circumference and a continuous circumferential groove, the wheels being mounted adjacent to each other with approximately mutually tangent circumferences; and the front end of the cage extending forward of the wheels, and forming a respective first and second curved edge with each respective side surface of the slot, each curved edge having an apex that is the forward-most point on the edge and also the point on the edge that is nearest the cage axis; whereby a cable can pass through the cage, between the two wheels, and a deviation of the cable forward of the wheels that is sufficient to contact either of the curved edges tends to rotate the cage, causing the wheels to align with the plane of the deviation, and causing the cable to fall into the respective groove in one or the other of the wheels.
