Abstract
Abstract A spring system mounted on a supporting bar which is rigidly fixed to an element of a remote manipulator is continuously applied against the motion-transmission belts or cables with a substantially constant force in order to take up the slack of these latter. The spring system is constituted by a series of parallel leaf-spring elements equal in number to the cables or belts to be tensioned, each element being constituted by an auxiliary spring-leaf applied against a main spring-leaf. A bridge-piece is fitted at the end of the main spring-leaf and mounted astride the corresponding belt or cable.

Claim 1
Independent Claim
116 words
A device for applying tension to belts or cables for a remote manipulator and comprising a spring system mounted on a supporting bar which can be rigidly fixed to an element of the remote manipulator, a spring system continuously applied against the belts or cables with a substantially constant force in order to take up the slack of said belts or cables, said spring system being provided with a series of parallel elements equal in number to the belts or cables to be tensioned, each element being provided with an auxiliary spring-leaf applied against a main spring-leaf having a bridge-piece fitted at the end of said main spring-leaf and mounted astride the corresponding belt or cable.
Claim 2
Independent Claim
116 words
A device for applying tension to belts or cables for a remote manipulator and comprising a spring system mounted on a supporting bar which can be rigidly fixed to an element of the remote manipulator, a spring system continuously applied against the belts or cables with a substantially constant force in order to take up the slack of said belts or cables, said spring system being provided with a series of parallel elements equal in number to the belts or cables to be tensioned, each element being provided with an auxiliary spring-leaf applied against a main spring-leaf having a bridge-piece fitted at the end of said main spring-leaf and mounted astride the corresponding belt or cable.
Claim 3
Dependent Claim
33 words
A device according to claim 1, wherein the bridge-piece provided at the end of each main spring-leaf is constituted by a bracket fixed on the leaf by means of rivets or other means.
Claim 4
Dependent Claim
