Document Type and Number:
WIPO Patent Application WO/2015/051524
Kind Code:
A1
Abstract:
Provided is a top center pivot-joint structure of a tent with a simple top. The top center pivot-joint structure comprises a center pivot-joint base (1) and at least three connecting sleeves (2) in pivot joint with the center pivot-joint base (1). At least three pivot-joint grooves (11) are formed in the center pivot-joint base (1) in a radial manner. Pivot joint holes (12) in pivot joint with the connecting sleeves (2) are formed in sidewalls of the pivot-joint grooves (11). Sealed openings are formed in upper portions of the pivot-joint grooves (11) of the center pivot-joint base (1). Protrusions (13) protruding into the pivot-joint grooves (11) are formed at the positions close to inner sides of the pivot-joint grooves (11), of the tops of the pivot-joint grooves (11). The connecting sleeves (2) are telescopically and movably disposed in the pivot-joint grooves (11) of the center pivot-joint base (1) in a pivot-joint manner. Upper sidewalls of the connecting sleeves (2) are in interference fit with the protrusions (13). After the tent is unfolded, the upper sidewalls of the connecting sleeves (2) and the protrusions (13) can be fitted in an embedded manner so as to implement a locking function, and therefore, the unfolded tent supports are more stable and do not collapse; conversely, when the tent is folded, an embedded relationship between the connecting sleeves (2) and the protrusions (13) is removed, and the tent supports are smoothly folded.
