Abstract: A tray and seat are adjustable vertically with respect to a base on a baby walker. Connecting means extending from the tray to the base is associated with a pawl having teeth meshed with a rack on the bottom surface of the tray. The meshed teeth are shaped so that the tray and seat can be elevated with respect to the base only by applying an upward force on the tray.

Abstract: First and second frame members on a stroller partially overlap one another and are generally parallel. A latch member is pivotably connected to the first frame member and biased to a position wherein it embraces an end of the second member. The latch member has a cam surface thereon so that finger pressures may be applied to pivot the latch frame member against the spring bias or so that the end of the second member may contact the surface and pivot the latch member whereby the second member will be snapped to a latched position without finger manipulation.

Abstract: A latch, particularly for a crib or the like, is spring biased to a latched position. A single fastener secures the latch member to a support and guides the latch for reciprocal movement.
