A mechanism for preventing removal of a ramp from its storage space beneath the floor of a truck body when the door for the truck body opening is latched closed. The ramp is insertable into and is removable from the ramp storage space through an opening beneath the truck body opening. The door latching mechanism includes a latch bolt movably mounted on the door and engagable with a catch pin in the truck body floor. The latch bolt carries a pawl which is engagable with a portion of the ramp to prevent removal of the ramp when the ramp is properly stored. The pawl also prevents the latch bolt from engaging the catch pin if the ramp is improperly stored.

Why it's free to use
- Filed March 29, 1990 and granted April 20, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 29, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 29, 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.
