Abstract

A foldable baby crib includes a bottom frame unit, lateral frame units, and upper and lower pivot connectors. Each lateral frame unit includes a pivot connection seat, a pair of support rods, each having a top rod end pivoted to the pivot connection seat, and a pair of top rods, each having an inner rod end pivoted to the pivot connection seat. The upper pivot connectors interconnect pivotally outer rod ends of the top rods of adjacent lateral frame units. The lower pivot connectors interconnect pivotally lower rod ends of the support rods of adjacent lateral frame units. The bottom frame unit is connected to the lower pivot connectors and is operable to convert the foldable baby crib from an expanded state to a folded state, where the lateral frame units are collapsed.

Dependent claims

A foldable baby crib comprising:

a bottom frame unit;
a plurality of lateral frame units, each including:
a pivot connection seat,
a pair of support rods, each of which has a top rod end pivoted to said pivot connection seat, and an opposite lower rod end, and
a pair of top rods, each of which has an inner rod end pivoted to said pivot connection seat, and an opposite outer rod end;
a plurality of upper pivot connectors, each of which interconnects pivotally said outer rod ends of said top rods of an adjacent pair of said lateral frame units;
a plurality of lower pivot connectors, each of which interconnects pivotally said lower rod ends of said support rods of an adjacent pair of said lateral frame units, and is connected pivotally to said bottom frame unit;
said bottom frame unit being operable to convert said foldable baby crib between an expanded state, where said bottom frame unit and said lateral frame units cooperate to define a crib space, and a folded state, where said bottom frame unit and said lateral frame units are collapsed;
and
wherein said bottom frame unit includes a hub and a plurality of connecting sections, each having an inner end connected to said hub, and an opposite outer end connected pivotally to a respective one of said lower pivot connectors.

A baby crib convertible between an expanded state and a folded state, comprising a plurality of lateral frame units, each forming a side of said baby crib when said baby crib is in the expanded state, and each including

a pivot connection seat,
a pair of support rods, each of which has a top rod end pivoted to said pivot connection seat, and an opposite lower rod end, and
a pair of top rods, each of which has an inner rod end pivoted to said pivot connection seat and an opposite outer rod end,
wherein said support rods of each of said lateral frame units form an inverted V-shaped configuration when said baby crib is in the expanded state,
wherein said lower rod ends of said support rods of each of said lateral frame units are close to each other, and said top rods of each of said lateral frame units are pivoted relative to said pivot connection seat when said baby crib is converted from the expanded state to the folded state;
a plurality of lower pivot connectors, each of which interconnects pivotally said lower rod ends of said support rods of an adjacent pair of said lateral frame units;
a bottom frame unit including a hub and a plurality of connecting sections, each having an inner end connected to said hub, and an opposite outer end connected pivotally to a respective one of said lower pivot connectors, and
wherein said hub is lifted upward to move said lower rod ends of said support rods of said lateral frame units close to each other when converting said baby crib from the expanded state to the folded state.
