A connection device for a flexible display screen defining a joint assembly, comprising:
- multiple main joints;
- and
- multiple subsidiary joints, the main and subsidiary joints being positioned in opposing and moving relationship with respect to each other;
- each main joint having a base section, a first arm and a second arm, the first and second arms being connected with two opposing ends of the base section, the first arm configured to have a first chamber positioned therein, the second arm configured to have a second chamber positioned therein and in facing relationship with the first chamber, and at least one resilient cantilever protruding from the base section to be positioned between the first and second arms;
- each subsidiary joint having a connection section and a first hand section extending from one end of the connection section and a second hand section extending from an opposing end of the connection section, each first hand section being displaceably disposed in a respective first chamber of a corresponding main joint and each second hand section being displaceably disposed in a respective second chamber of an adjacent main joint, each first hand section being in contact with the resilient cantilever of the corresponding main joint and each second hand section being in contact with the resilient cantilever of the adjacent main joint;
- wherein each of the first hand sections and the second hand sections is displaceable between a first position and a second position and releasably held thereat by the contact of a respective resilient cantilever with a respective first hand section and a respective second hand section;
- wherein each subsidiary joint is rotationally movable about a rotational axis defined between adjacent ones of the multiple subsidiary joints, the adjacent ones of the multiple subsidiary joints being rotationally moved between an open position of the flexible display screen and a closed position of the flexible display screen, the first and second hand sections being in the first position in correspondence with the open position of the flexible display screen and in the second position in correspondence with the closed position of the flexible display screen, and the main joints being disposed in contiguous relationship one to another in the open position of the flexible display screen and angularly displaced from one another about the rotational axis in the closed position of the flexible display screen;
- wherein each resilient cantilever has a head section, the head section and the first and second arms of a corresponding main joint defining a respective first opening in communication with the first chamber and a respective second opening in communication with the second chamber, the head section having an arched face and a first interference section and a second interference section positioned on opposing ends of the arched face, the first interference section and the first arm defining a width of the first opening, the second interference section and the second arm defining a width of the second opening;
- wherein each subsidiary joint has a first wing section and a second wing section respectively protruding from the opposing ends of the connection section to respectively correspond to positions of the first and second hand sections;
- a first pivotal connection board, the first pivotal connection board having a first hook section and a wing section;
- and
- a second pivotal connection board, the second pivotal connection board having a second hook section and a wing section;
- wherein the first hook section extends into the first chamber of a corresponding main joint located at one end of the joint assembly, and wherein the second hook section extends into the second chamber of a corresponding main joint located at an opposing end of the joint assembly.
