Open the CIPO recordAbstract From the Canadian patent
The invention concerns a transmission cable link (14) between a drive pulley (15) and a driven pulley (22) rotating a mobile member (5) comprising two strands (23 24) linking the driven pulley (22) to idle pulleys (17 18) which are substantially aligned with an axis (Y) of rotation of an intermediate part (2) between the member (5) and the base plate (1) whereon the motor (12) is fixed. Thus the motor (12) is arranged on the two optionally fixed parts and the rotation of the support (2) has hardly any effect on the tension of the cable (14) thereby enabling its constant proper operation. The invention is particularly applicable to articulated robot arms.

Why it's free to use
- Filed November 15, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 15, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
