<p>The mattress frame adjuster is for the adjustment of the foot or head section of a mattress frame, with a toothed rack (3), a slider (6) running on it and a connecting link controlling a contact tongue (7) which is attached to a double lever (9) having a linked connection to the toothed rack (3). The double lever connecting the toothed rack to the adjustable frame (2) is splayed in a fork shape having an angle of at least 30 degrees between the legs of the fork. From the fulcrum (8) between the toothed rack (3) and the double lever (9) an inclined support lever (13) provides a stay connection to a fixing (5) to be fitted to the mattress frame.</p> |
