This invention relates to a drop leaf table angular adjustment mechanism. The leaf and tabletop are pivotally connected with a hinge, in which a positioning ratchet plate with multiple angular positioning ratchet teeth to the underside of the tabletop hinge. On the rear of the leaf hinge set, there consists of a positioning plate with a curvature slot. The positioning ratchet plate and positioning plate are pivotally connected with a pivot bolt to form a mechanism for the providing the leaf angular lean adjustment. On the backside of the positioning plate there is a ladle-shape pawl on the downside of the positioning ratchet plate, wherein the pawl engages with any of the ratchet teeth of the positioning ratchet plate to obtain a relative stop position between the tabletop and leaf. The operation which releases the pawl from engagement can adjust the leaf to an arbitrarily lean angle adjustment. |
