Abstract:
An adaptable frame carrier with triaxial freedom of movement for couches and seats, in which the freedom of movement is achieved in the x-, y- and z-direction by a system of spring loaded elements movable relative to one another, the couch or seat having a frame, the adaptable frame carrier comprising:at least one pressure resistant rolling plate;at least one dome shaped rolling body having a rolling radius R1 and operably engaging and rolling along said at least one pressure resistant rolling plate in the x- and y-direction;a frame connection plate operably mounted on the frame;an upper and a lower cylinder slidably engaging each other, wherein one of said upper and lower cylinders is connected to said frame connection plate in a spring loaded hinged configuration;a compression spring operably supporting said upper and lower cylinders against each other in a z-direction; anda connecting element connecting at least one of said upper and lower cylinders with said frame connection plate and being operable to make moveability between the x-, y- and z-direction interdependent on one another;wherein said at least one dome shaped rolling body and said upper and lower cylinders form an inner rolling element having a semicircular radius R2, said rolling radius R1 being greater than said semicircular radius R2.
