US 7,922,244 B2 · Tray latch mechanism for high chair

Abstract

A latch mechanism for child's high chair tray assembly having a tray post and socket mounting arrangement has a central, front actuation button that moves a slide link mounted underneath the tray assembly. The slide link is connected to an actuation arm slidably mounted within each respective tray post. The actuation arm includes a cam surface that pivots a latch member having a rectangular lock pin that extends below the tray post into engagement with openings in the socket receiving the tray post. The latch member is spring loaded into engagement with the socket openings. The front surface of the arm rests are sloped to cam the lock pin into the tray post to permit a passive mounting of the tray onto the high chair, but the lock pin engages the first socket opening to require a non-passive manipulation to affect positional adjustment or removal from the high chair.

Dependent claims

A latch mechanism for a tray system formed with tray posts for mounting on a child's high chair having laterally spaced arm rests formed, respectively, with a socket to receive said tray posts, comprising:

a latch member movably mounted within each said tray post and having a lock pin projecting out of said tray post, said lock pins being engageable with the corresponding said arm rest to affect a retraction of said lock pin into said tray post in response to said tray post being initially inserted into the respective said socket;
and
an actuation arm slidably mounted within each said tray post for engagement with said latch member to affect a pivotal movement thereof to retract said lock pin into said tray post.

A tray system for a child's high chair having arm rests, each said arm rest being formed with a longitudinally extending socket, comprising:

a tray member formed with rearwardly extending tray posts alignable with said sockets so as to be positionable within said sockets;
and
a latch mechanism including a centrally positioned actuator member, a slide apparatus, and a spring-biased latch member having a lock pin extendable from each said tray post to engage selected openings formed in the corresponding said sockets, said slide apparatus lifting said spring-biased lock pins from said selected openings engaged therewith when said actuator member is manipulated to allow said tray posts to be positionally adjusted within said sockets, said slide apparatus including:
a slide link connected to said actuator member and being slidably mounted beneath said tray member;
and
an actuator arm slidably mounted within each said tray post, each said actuator arm being connected to said slide link, said actuator arm being engageable with said latch member when said actuator member is depressed.
