Abstract: A foldable bed frame includes left and right longitudinal stands. Each of the left and right longitudinal stands includes first and second longitudinal bars pivotally connected to a third longitudinal bar at first and second pivotal points, respectively. Each of the left and right longitudinal stands also includes first, second and third vertical legs fixedly coupled to or integrally formed at the first, second and third longitudinal bars, respectively. The distance between the first vertical leg and the first pivot point is different than the distance between the second vertical leg and the second pivot point such that when folded, one of the first and second vertical legs is disposed in an interior side of the folded left or right longitudinal stand with respect to the other of the first and second vertical legs.

Abstract: Disclosed are supports, folding mechanisms and foldable supporting frames. A foldable supporting frame includes a plurality of bent bars, folding mechanisms and supports. The bent bars are connected to each other by the folding mechanisms and the supports to form upper and lower frames of the foldable supporting frame. The foldable supporting frame can be folded and unfolded by rotating any one of the bent bars. When unfolded, the supports hold the upper frame in place and keep it flat and stable. When folded, the folding mechanisms and the supports allow the bent bars to move toward each other and fold onto each other. The folded supporting frame is compact and of a regular shape, making it easier to handle, package, store, and transport.

Abstract: Disclosed are tents and tent support frames. A tent support frame includes a rotatable connector and tent support poles. The rotatable connector includes first and second connectors configured to be coupled in a vertical direction with one above another, and rotatable with respect to each other. The first connector includes a first through-hole in a horizontal direction, and the second connector includes a second through-hole in the horizontal direction. Tent support poles include a first tent support pole configured to pass through the first through-hole of the first connector, and a second tent support pole configured to pass through the second through-hole of the second connector.

Abstract: A foldable tent includes a tent cloth, a plurality of support frame poles to support the tent cloth, and a tent top supporting device. The tent top supporting device includes a cover, a plurality of connection sleeves, and a plurality of inwardly concave recesses. The plurality of inwardly concave recesses is disposed at a peripheral side of the cover. Each recess includes a first side wall and a second side wall disposed on two sides of the recess, and an inner side wall adjacent a center of the cover. Each respective connection sleeve is flippably or rotatably disposed in a corresponding recess, and has one end connected to an end of a corresponding support frame pole. When the foldable tent is unfolded, a side wall of the other end of the corresponding connection sleeve comes into contact and matches with the inner side wall of the corresponding recess.

Abstract: A foldable supporting frame includes a first frame set, a second frame set, and a first link at each of the left and right sides of the foldable supporting frame to pivotally connect the first frame set with the second frame set. Each of the first and second frame sets includes a first frame unit, a second frame unit, and a second link at each of the left and right sides of the foldable supporting frame to pivotally connect the first frame unit with the second frame unit. The first link allows the first and second frame sets to fold and unfold with respect to each other, and the second link allows the first and second frame units to fold and unfold with respect to each other. As a result, the supporting frame can be folded at least three times and has a much smaller folded size.

Abstract: A foldable table may include a table top and legs that are movable between an extended position and a collapsed position. The table top may include a first section and a second section that are connected by a hinge assembly. A locking member may be sized and configured to lock the hinge assembly in a fixed position. Advantageously, moving the legs between the extended and collapsed positions may cause the locking mechanism to move between the locked and unlocked positions. Thus, when the legs are in the extended position and the locking mechanism is in the locked position, the table top may be secured in the unfolded position.
