The invention relates to an armchair tablet hinge system. According to the invention, the tablet (1) is mounted to an armrest of the armchair by means of a support (4), said support containing a hollow shaft (5). The end of the hollow shaft is provided with a head (6) to which the tablet (1) is articulated by means of a cam-shaped element (7). In addition, rod (10) is housed in the aforementioned shaft (5) and is pushed against the cam-shaped element (7) by means of a spring (11). Moreover, the end of the rod (10) can be inserted into a notch (13) in the cam (7) in order provisionally to block the rotation of the tablet (1).

The invention claimed is: 1. An armchair tablet hinge system for rotating and folding a tablet with respect to an armrest of an armchair comprising: a support affixable to the armrest; a rotatory hollow shaft rotatably housed in the support and having a head at one end of the shaft, the head projecting out from a front end of the support; a cam affixable to the tablet, the cam rotatably mounted in the head of the shaft to provide articulation of the tablet; a rod axially housed in the shaft and pushed by a spring to project one end of the rod through the head to provide a sliding rest against the cam; a notch in the cam abutting the one end of the rod to provide provisional blocking of the rotation of the tablet; an angular notch at a rear end of the support; a bolt affixed perpendicular axially to the shaft and in the angular notch to limit rotation of the shaft with respect to stop position of ends of the angular notch; and a torsion spring acting on the shaft to rotate the shaft in a direction to make the tablet fall into a folded position under the armrest. 2. An armchair tablet hinge system for rotating and folding a tablet with respect to an armrest of an armchair comprising: a support affixable to the armrest; a rotatory hollow shaft rotatably housed in the support and having a head at one end of the shaft; a cam affixable to the tablet, the cam rotatably mounted in the head of the shaft to provide articulation of the tablet; a rod axially housed in the shaft and pushed by a spring to project one end of the rod through the head of the shaft; and a roller rotatable mounted on the one end of the rod, the roller abutting a notch in the cam to provide rotational support and a sliding rest to the cam, the notch providing provisional blocking of the rotation of the tablet. 3.
