Abstract
Abstract A push-pull cable arrangement for selectively transmitting longitudinal motion to two separate destinations has an inner wire having a front end, a rear end and an intermediate node between the front and rear ends. The inner wire is enclosed with a first outer casing between the front end and the intermediate node, and with a second outer casing between the intermediate node and the rear end. A front end of the first casing facing the front end of the wire is stationary, and a rear end of the second casing facing the rear end of the inner wire is also stationary. There is further provided an intermediate unit having a first member to which a rear end of the first casing is fixed, and a second member to which a front end of the second casing is fixed. One of the first and second members is a stationary housing, and the other is a sliding member slidably contained in the housing. The housing and the sliding member receives the inner wire with the intermediate node slidably, and the sliding member is movable longitudinally of the wire in the housing. When the inner wire is pulled, the sliding member abuts against the housing and can not move, so that a pull motion is transmitted to the rear end of the wire. When the wire is pushed, the intermediate node causes the sliding member to move away from the housing, and this movement is transmitted to another destination.
