A rail including a number of slots being longitudinally formed therein and a number of options each including a guide being slidably engageable in the slots. Each slot consists of a wide portion and a narrow portion. The wide portion of each slot is proximate to the axis of the rail while the narrow portion of the same is distal from the axis of the rail.

Why it's free to use
- Filed December 9, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 9, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 9, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
