Control cable and remote control device using the same

Abstract

The control cable includes a reinforcing wire 11 of which the both ends are fixed by anchors 14, 14, an outer casing 12 made of synthetic resin so as to be slidable to the reinforcing cable, and so as not to constrain the thermal deformation in the axial direction based on the variation of ambient temperature, and an inner cable 13 made of metal having flexibility housed in the outer casing 12 slidably. In the both ends of the inner cable, cable ends 17, 17 coupled to an operating member and an operated member are firmly fixed

1 . A control cable, comprising:

       5 . A control cable according to  claim 1 ,
 wherein the reinforcing wire is composed of a single wire made of metal, and the inner cable composed of a plurality of twisted wires of metal element wires.   
   
   
       6 . A control cable according to  claim 1 ,
 wherein the reinforcing wire and the inner cable respectively are composed of a single wire made of metal.   
   
   
       7 . A remote control device, comprising:
 an operating member which gives an operating force;   a bracket of operation side;   an operated member to receive the operation of the operating member through the control cable according to  claim 1 ; and   a bracket of operated side;   wherein the both ends of the reinforcing wire of the control cable are fixed to the brackets of the operating side and the operated side,   at least one end of the outer casing of the control cable is held slidably in the axis direction by the bracket of the operating side or the operated side, and   the both ends of the inner cable of the control cable are coupled to the operating member and the operated member.   
   
   
       8 . A remote control device according to  claim 7 ,
 wherein the operating member and the operated member are pulleys provided turnably within a predetermined angle to the each bracket,   the outer casing exhibits the ribbon-like shape,   the reinforcing wire is provided slidably along the center of the outer casing, at the same time, the inner cable is provided as one pair, and these inner cables are provided slidably along the both side edges of the outer casing.   
   
   
       9 . A remote control device according to  claim 8 ,
 wherein at least one end side of the ends of the one pair of the inner cable are firmly fixed by one cable end mutually in a lump, and the cable end is engaged with the pulley of the operating side or the pulley of the operated side.   
   
   
       10 . A remote control device according to  claim 7 ,
 wherein the operating member or the operated member is a pulley provided rotatably to the bracket,   the inner cable is wound around the pulley with more than one turn, and at the same time, the end of the inner cable is engaged with the pulley.
