Abstract
To replace conventional ball-cage strips for remote controls in which push-pull blades slide on ball bearings maintained properly spaced from one another by such strips, a linkable ball-cage element has been developed to form strips of such linked elements that overcome limitations of prior ball-cage strips. Each element has a head and neck at one end and a cavity and narrow entrance at the opposite end so that the head of one element can be inserted into the cavity of another element. Each element holding a ball is thus linked with other elements to provide a very flexible strip of any desired length.
