Research in deployable structures increased in the last decade, due to the need of building structures that can change their shape or functionality in response to varying of different aspects: climatic conditions, environment, functional requirements or emergency situations. Depending on how the transformation is doing, transformable structures can be deployable or demountable, as a kit-parts system. These structures can be classified in four main groups: structures based on spatial articulated bar mechanisms; foldable plate structures; tensegrity structures; and membrane structures. In this paper, some geometric design aspects of curvilinear bar mechanisms are discussed and a curvilinear structure mechanism is proposed. More results on the geometric design, dimensional synthesis and simulation of this scissor structural mechanism will be presented in future work.
