<p>The invention relates to an anchoring foot for chairs positioned at desks, comprising a column (1) having a lower anchor (2) for securing same to the ground and an upper supporting element (3), rotatably coupled thereto, for securing the body of the chair (13). The supporting element (3) includes a carriage (7) which can move longitudinally along a guide (8) forwards and backwards in relation to the desk (17) and which can rotate in relation to the column (1). In addition, the supporting element (3) can include a lower cam (25) positioned facing another complementary upper cam (22) that is inserted therein by means of helical tracks (24). The lower cam (25) is pushed upwards by the return force of a spring (27), thereby rotating the upper cam (22) and rotating the seat to the initial position thereof.</p> |
