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 the 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. Front and rear ends of the first outer casing are held stationary. A front end of the second outer casing facing the intermediate node of the inner wire is movable, and a rear end of the second outer casing facing the rear end of the inner wire is held stationary. When the front end of the inner wire is pulled, a longitudinal motion of the inner wire is transmitted to the rear end of the inner wire, by which a first receiving unit is moved. When the front end of the inner wire is pushed, the intermediate node of the inner wire pushes the front end of the second outer casing, by which a second receiving unit is moved.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
299 words
A push-pull cable arrangement for transmitting longitudinal motion, comprising a wire having a front end, a rear end and an intermediate node between the front and rear ends, a first casing enclosing the wire between the front end and the intermediate node, and having a front end and a rear end, a second casing enclosing the wire between the intermediate node and the rear end, and having a front end and a rear end, an input unit having a stationary member to which the front end of the first casing is fixed, and a movable member connected with the front end of the wire and capable of pulling the wire from the first casing and pushing the wire into the first casing, an intermediate unit having a stationary member to which the rear end of the first casing is fixed, and which holds the intermediate node and allows the intermediate node to move longitudinally, the front end of the second casing abutting against, the stationary member of the intermediate unit so as to prevent the distance between the rear end of the first casing and the front end of the second casing from decreasing when the wire is pulled, the intermediate node pushing the front end of the second casing and moving the front end of the second casing away from the stationary member of the intermediate unit when the wire is pushed, link means connected with the front end of the second casing and caused to move in accordance with the movement of the front end of the second casing, a first receiving unit having a first member connected with the rear end of the wire, and a second member connected with the rear end of the second casing, a second receiving unit connected with the link means.
Claim 2
Dependent Claim
299 words
A push-pull cable arrangement for transmitting longitudinal motion, comprising a wire having a front end, a rear end and an intermediate node between the front and rear ends, a first casing enclosing the wire between the front end and the intermediate node, and having a front end and a rear end, a second casing enclosing the wire between the intermediate node and the rear end, and having a front end and a rear end, an input unit having a stationary member to which the front end of the first casing is fixed, and a movable member connected with the front end of the wire and capable of pulling the wire from the first casing and pushing the wire into the first casing, an intermediate unit having a stationary member to which the rear end of the first casing is fixed, and which holds the intermediate node and allows the intermediate node to move longitudinally, the front end of the second casing abutting against, the stationary member of the intermediate unit so as to prevent the distance between the rear end of the first casing and the front end of the second casing from decreasing when the wire is pulled, the intermediate node pushing the front end of the second casing and moving the front end of the second casing away from the stationary member of the intermediate unit when the wire is pushed, link means connected with the front end of the second casing and caused to move in accordance with the movement of the front end of the second casing, a first receiving unit having a first member connected with the rear end of the wire, and a second member connected with the rear end of the second casing, a second receiving unit connected with the link means.
Claim 3
Dependent Claim
42 words
The push-pull cable arrangement according to claim 1, wherein the link means comprises a lever pivoted, at one end, on the stationary member of the intermediate unit and having a swingable end connected with the front end of the second outer casing.
Claim 4
Dependent Claim
31 words
The push-pull cable arrangement according to claim 1, wherein the second receiving unit comprises a rod having one end connected with the lever between the swingable end and the pivoted end.
Claim 5
Dependent Claim
38 words
The push-pull cable arrangement according to claim 3, wherein the second member of the first receiving unit is stationary, and the rear end of the second casing is fixed to the second member of the first receiving unit.
Claim 6
Dependent Claim
29 words
The push-pull cable arrangement according to claim 4, wherein the second casing has a greater capability of being bent when it is pushed than that of the first casing.
