I am looking for some device that can be used for blocking a sheet of glass or other materials in position. On one side of the glass (blue sheet in the diagram) is applied a force if the force is above a certian value the upper block is released and the glass is free to move upward.
I am looking for a kind of force limiting relief device but I can't find anything already on the market? Am I missing something? Is there any conventional name for such devices?
