Abstract: A foldable frame includes first and second units pivotally coupled with each other at their proximal sides and rotatable with respect to each other between a folded state and an unfolded state. The foldable frame also includes a middle leg assembly coupled with the first and second units at the proximal sides of the first and second units. The foldable frame further includes a safety enhancement assembly having a first enhancement member, a second enhancement member and a locking mechanism. The first enhancement member is connected to the first unit and the middle leg assembly. The second enhancement member is connected to the second unit and the middle leg assembly. The locking mechanism selectively locks the first and second enhancement members when the first and second units are in the unfolded state, and thus prevents accidental folding of the first and second units.

Abstract: Disclosed are telescopic poles and tent frames having telescopic poles. A telescopic pole includes an inner tubular pole, an outer tubular pole, and a locking/unlocking mechanism to control relative movement of the inner and outer tubular poles. The locking/unlocking mechanism is operable between a locking state and an unlocking state. In the locking state, the locking/unlocking mechanism restricts the inner and outer tubular poles from moving toward each other but allows the inner and outer tubular poles to move away from each other. In the unlocking state, the locking/unlocking mechanism allows the inner and outer tubular poles to move toward as well as away from each other.

Abstract: Disclosed are supporting assemblies and foldable structures having supporting assemblies. A supporting assembly includes a locking mechanism that is easy to operate. The locking mechanism is configured to lock the supporting assembly in an unfold state to prevent inadvertent folding of the supporting assembly. It can be unlocked easily when folding the supporting assembly is desired. Additionally or optionally, the supporting assembly includes a protecting component configured to enhance safety during the operation of the locking mechanism.

Abstract: A tent frame includes extension poles, first connectors and supporting poles. For each respective extension pole, the corresponding first connector includes a first coupling member and a second coupling member facing away from a central axis of the tent frame. The corresponding supporting pole has an upper end connected to the first coupling member of the corresponding first connector and the respective extension pole has an end pivotally connected to the second coupling member of the corresponding first connector. At least a first portion of the corresponding supporting pole has a first surface that is substantially flat and faces away from the central axis of the tent frame. When the frame is folded, the respective extension pole is folded onto the first surface of the corresponding supporting pole, and thus minimizes a size of the tent frame when folded.

Abstract: A frame includes a middle unit, a first unit and a second unit. Each of the middle, first and second units includes pivotally connected longitudinal members. Each of the first and second units also includes lateral members pivotally connected to its longitudinal members and the middle unit. The lateral and longitudinal members of the middle, first and second units are foldable onto each other, making the frame very compact when folded. The lateral members of at least one of the first and second units are adjustable in length, allowing the frame to adjust its dimension in a lateral direction when unfolded. Additionally or optionally, at least one longitudinal member of the first unit and at least one longitudinal member of the second unit are adjustable in length, allowing the frame to adjust its dimension in a longitudinal direction when unfolded.

Abstract: A foldable unit includes a first section, a second section and a connection section. The first and second sections are pivotally coupled with each other at their proximal sides. The connection section has a first side pivotally coupled with a peripheral bar of the first section and a section side for detachably coupling the connection section with a structure. The foldable units can be used to make frames at different widths when unfolded to meet different needs of users and stackable when folded to save spaces.

Abstract: A table includes a supporting frame and a panel assembly supported by the supporting frame. A panel assembly includes a panel, a plurality of connectors, and one or more elongated members connected to the panel by the plurality of connectors. The one or more elongated members include a first elongated member disposed adjacent to but spaced apart from a first portion of the outer periphery of the panel, creating a gap in between. The presence of the gap allows one to hang objects, such as water bottles, bags, umbrellas, directly or indirectly to the first elongated member.

Abstract: A foldable structure includes an elongated shaft having at least one non-circular portion. The foldable structure also includes a first mounting assembly with a proximal side fixedly connected to the shaft to restrict rotation of the first mounting assembly relative to the shaft and a second mounting assembly with a proximal side rotatably connected to the shaft to allow rotation of the second mounting assembly relative to the shaft. A first panel is fixedly connected to the first mounting assembly, and a second panel is fixedly connected to the second mounting assembly. The at least one non-circular portion of the shaft has an upper surface that remains in contact with a proximal side of the first panel, and when the foldable structure is unfolded, abuts upwardly against the proximal sides of the first and second panels to help to level the first and second panels.

Abstract: A foldable table includes first and second panels, first and second mounting assemblies coupled respectively with the first and second panels, and first and second leg assemblies coupled respective with the first and second mounting assemblies. Each of the first and second panels is formed with upper and lower panel surfaces spaced apart at a first distance. Each of the first and second panels is also formed with a ridge or protrusions or both of the ridge and protrusions. A lower surface of the ridge is spaced apart from the upper panel surface at a second distance equal to or less than two times the first distance. A lower surface of each protrusion is spaced apart from the upper panel surface at a third distance equal to or less than 1.5 times the first distance. Thus, when folded, the table has a minimized thickness.
