Abstract
The present disclosure relates to a frame which comprises a front surface, extended by two lateral posts and two arms hinged to the posts about the hinge pins of two telescopic hinges, each of which, with a front surface element rigidly connected to a post and an arm element, is rigidly connected to an arm that comprises a slide hinged on the front surface element, and mounted in a sheath against a spring and slidable by means of the latter; the front surface element and the sheath of the arm element engaging, in the open position of the arm, by at least two matching transverse surfaces for stopping the opening. The surfaces that stop the opening of the two elements of each hinge are rough, the surface that stops the opening of one of the elements, of the surface, and of the arm having a hollow intermediate area. Thanks to the present method, system and device, the frame hinges have a reduced size with the same performance.
