CHILD PLAY ENCLOSURE FRAME
Document Type and Number:
WIPO Patent Application WO/2020/143623
Kind Code:
A1
Abstract:
A child play enclosure frame, comprising: a plurality of vertical rods (2) respectively provided with upper frame corner joints (13) and lower frame corner joints (37), an upper frame (1) that is connected between the plurality of upper frame corner joints (13) and that is capable of folding, a lower frame (3) that is connected between the plurality of lower frame corner joints (37) and that is capable of folding, and an upper frame locking apparatus (100) used for locking the upper frame (1) in an unfolded position. The lower frame (3) comprises a center seat (34) located in at a middle portion, a plurality of bottom link sets (30) connected between the center seat (34) and corresponding lower frame corner joints (37). The center seat (34) comprises an upper center set (35) and a lower center set (36) capable of relative vertical movement, a triangular mechanism capable of deformation is formed between each of the bottom link sets (30) and the upper center set (35) and lower center set (36), and a four-linkage mechanism capable of deformation is formed between the foregoing sets and the vertical rods (2). When the child play enclosure frame is in the unfolded position, the lower frame (3) structure is stable. When the upper center set (35) performs an upward relative motion relative to the lower center set (36), the triangular mechanism and the four-linkage mechanism deform simultaneously, which may force the plurality of vertical rods (2) to remain upright or remain in a state of being approximately upright and synchronously drawing together towards the center, which forces the entire play enclosure frame to fold and collapse.
