Claim:
A support assembly configured to support a moveable barrier which moves between open and closed positions in an opening in a wall comprising: a track configured for attachment to the wall which track guides movement of the barrier between a substantially vertical closed position and a substantially horizontal open position, the track having a vertical portion and a horizontal portion and a curved portion therebetween; a jack shaft configured for attachment to the barrier for movement thereof and having a longitudinal axis perpendicular to the track, the jack shaft having an end portion; a bayonet mount having a longitudinal axis perpendicular to the track; a drive unit; and a support member coupled to the track at about the curved portion thereof and which support member supports and holds the drive unit away from the wall, the drive unit coupled to the support member in a lockable engagement via the bayonet mount, the connection between the bayonet mount and the support member effective to support and hold the drive unit against the support member and above the ground, the longitudinal axis of the jack shaft being aligned with the longitudinal axis of the bayonet mount such that the end portion of the jack shaft extends through at least portions of the bayonet mount into the interior of the drive unit to power the jack shaft for rotational movement around the longitudinal axis of the jack shaft and to move the barrier and the support member holding the drive unit and supporting the drive unit with the track away from the wall and limiting rotational movement of the drive unit being translated to the wall.
