EpitrochoidDoor

One design variant of the TorgglerDoor is the epitrochoidal design. Here, the power transmission between the rectangles is accomplished with a combination of a wheel and a cycloid curve. This object is also 100% balanced and smooth. The difference to the other objects however is that it is a pure gravity object. It would not work in outer space or in horizontal position. An additional coupling is necessary for the functionality, which must be however only little force-loaded. Such a coupling can be strings, but also curved segments or a light linkage. With this design, slender objects can be realized and it is also particularly suitable for rectangles with relatively different side lengths.
