One of the big issues when setting up for a show is bridging the tables. Normally the display is over 14 feet. The only true bridge is the one from the end module to the Space Port. But this is towards the end of the display and never falls on the table gap. Normally it will come some where after the main entrance and before the display starts to curve.
There are two main issues. First is the obvious table gap and the fact that two tables are not necessarily the EXACT same height. Remember that Lego dimensions are extremely precise. Also we have seen tables that have a small (1/8 to 1/4 inch) rim around the table, which is causes a height imbalance. The other issue is the weight of the MOC. Some tables, especially the plastic fold up tables, will sag in the middle because of the weight. This causes the module interface to be rising on an angle when the module on the other table is flat. Connecting the two becomes difficult.
If I try to place the table gap underneath the middle of a module, then both ends of that module are placed in distress. There is just not a good answer with the existing design.
My solution is a hinged connector.
What this is a double hinge. If you look carefully at the first picture, the goal of this connector is to connect an edge any just about any angle to another edge at a different angle. One hinge joint will not do this. It will take to serial hinges to adjust to the level and angle. Obviously these is a limit to what can be compensated. Also there is no guarantee that the linear distance between the two will be a Lego dimension. But that can be compensated for with scenery and landscaping.
These two pictures show the connection between two cliff modules. It is very similar to the other connections that will be made.Technic bricks are used to connect to the modules on either side. Then a 1 x 2 modified plate with bar and one with two clips are used to connect and form the movable hinge. There are three connection on the right side. This is meant to be the more permanent side. The left side with only two connections, is meant to be where final connection is made. It will be easier to make two rather than three connections.
