Open the CIPO recordAbstract From the Canadian patent
A double reach shuttle assembly (20) for a storage and retrieval machine. Latch mechanisms (82) are provided on the movable elements (22, 23 24, 25) of the, shuttle to control the sequence of extension of the movable elements thereby reducing the amount of space required beneath a load in a storage rack to accommodate the shuttle elements when the double reach shuttle is used in a single reach mode. As the shuttle extends each movable element remains stationary until the element above it reaches a predetermined point relative thereto. The invention further provides an additional latch mechanism (124) which insures that the load carrying element (25) of the shuttle is the last to retract.

Why it's free to use
- Filed July 17, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 17, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 17, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
