  • Publication number: 20080096463
    Abstract: Disclosed herein is an activity play set including an upper cabinet portion telescopically movable with respect to a lower cabinet portion. The play set is reconfigurable between a collapsed, lower configuration and an extended, higher configuration. A latch mechanism secures the upper cabinet portion in position relative to the lower cabinet portion. The latch mechanism is fixed to the lower cabinet portion and includes outwardly-biased slide members. As the upper cabinet portion and lower cabinet portion slide relative to each other, the outwardly-biased slide member ends contact and slide along slide walls of the upper cabinet portion. Furthermore, the slide walls of the upper cabinet portion include lock openings to receive the slide member ends. To release the latch mechanism to permit the upper cabinet portion to slide relative to the lower cabinet portion, the slide members are compressed inward to retract the slide member ends from the lock openings in the slide walls.
