<p>A latch mechanism (50) for a tray system (30) of a child's high chair having a tray post (35) and socket mounting arrangement includes a central, front actuation button (52) that moves a slide link (53) mounted underneath the tray system (30). The slide link (53) is connected to actuation arms (57) slidably mounted within respective tray posts (35). Each actuation arm (57) includes a cam surface (58) that pivots a respective latch member (55) having a rectangular lock pin (55a) which extends below a respective tray post (35) into engagement with openings in a respective socket (28) receiving the respective tray post (35). Thelatchmember (55) is spring-loaded into engagement with the openings. Front surfaces of arm rests (23) of a high chair structure (10) are sloped to cam the lock pins (55a) into respective tray posts (35) to permit passive mounting of the tray system (30) onto the high chair structure (10), but a non-passive manipulation is required once each lock pin (55a) is engaged to the openings in the sockets (28) to affect positional adjustment or removal from the high chair structure (10).</p> |
