Synthesis of the Mechanisms Used to Actuate the Cabinet Doors

摘要

The paper presents three kinematic schemes of planar mechanisms with bars used to open/close a cabinet (buffet). The mechanisms are mounted on the left and right walls of the cabinet, working in parallel, in a vertical plane. Both mechanisms are hinged to a single door that swings 90° in a vertical plane from a vertical position (closed) to a horizontal position (open). The three kinematic schemes proposed for door actuation have in their structure either only revolute joints (RRRR) or revolute and prismatic joints in the variants RRTR and RRRT. To each of the three kinematic schemes of mechanisms, an analytical method of geometric synthesis for two and three associated positions has been presented.
