Systems for releasably securing a platform
A system for releasably securing a platform in a raised position is disclosed. A track is provided. An arm is connected at a first end to the platform. A second end, with a lug, is biased toward a side portion of the track. The lug is configured to ride in the track. As the platform is raised, the lug rides upward and enters the top portion and clears a first vertical wall, whereupon the lug rests in the depression and thus supports the platform in the raised position. As the platform is raised further, the lug clears a second vertical wall, whereupon the lug can ride downward in the side portion and through a bottom portion, past a door and out an open end of the bottom portion.
