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 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 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.

Abstract: Disclosed are pivoting mechanisms, sliding mechanisms, frames and tables. A pivoting mechanism includes a first coupling piece, a second coupling piece and a rod. The first and second coupling pieces are pivotally coupled with each other. The rod is operated by gravity to automatically lock or unlock the first and second coupling pieces. A sliding mechanism generally includes a slider and a locking member. The slider includes a sleeve to be slidably coupled with a bar. The locking member includes a restriction piece, operated by an elastic piece to be disposed inside of the bar, to automatically lock the sleeve at a certain position of the bar.

Abstract: A foldable rocking chair frame includes a left side stand and a right side stand. Each stand includes a rocking structure and a plurality of supports interconnected and foldable into each other. The rocking structure includes an arched member, a slider, and one or more links. When the frame is unfolded, the arched member has an end portion disposed at the rear side of the frame and extends from the rear side of the frame toward the front side of the frame. The slider is disposed at the arched member and slidable along the arched member. Each of the one or more links is pivotally connected to the arched member and a support in the plurality of supports. The left and right side stands are connected by a connecting assembly that allows the left and right side stands to fold into each other.

Abstract: A mounting structure for a bedstead includes a side rail and a cross rail of the bedstead. The side rail and the cross rail are connected by a connecting member and an inserting member. The connecting member includes a body. The body is provided with a U-shaped groove in which the cross rail is clamped and a first hole located in a middle part of the U-shaped groove. The side rail is provided with a second hole matching with the first hole; and the inserting member is connected to the cross rail after sequentially passing through the second hole and the first hole. The use of the connecting member and the inserting member allows a quick and detachable connection between the side rail and the cross rail, facilitating storage and transportation.

Abstract: A foldable frame with enhanced stability includes a mounting assembly, a first leg assembly and a second leg assembly. Each of the first and second leg assemblies are pivotally coupled with the mounting assembly and rotatable with respect to the mounting assembly between a use position and a storage position. Each of the first and second leg assemblies includes a substantially straight first leg and a substantially straight second leg. The first and second legs are slanted outwardly to increase the supporting area and thus enhance the stability of the foldable frame and stability of other structures supported by the foldable frame.

Abstract: A tent frame includes a detachable illumination device with a casing to house batteries, a light source to emit light, a coupler and a first cover. The casing includes a first member. The coupler includes a second member, and one or more electrically-conductive members for electrically connecting the batteries. The second member is movable relative to the first member in a first direction to facilitate engagement/disengagement of the coupler with/from the casing. The second member is immovable relative to the first member in a second direction to prevent the one or more electrically-conductive members from misaligning with the batteries. The first cover is movable relative to the coupler in the first and second directions. When connected to the casing, the first cover pushes the coupler in the first direction toward the batteries and presses the one or more electrically-conductive members against the batteries to ensure electrical connection.

Abstract: A blow-molded unitary structure includes a panel having first and second panel walls and a generally hollow interior between the first and second panel walls. The structure also includes one or more different types of strengthening elements monolithically formed with the panel and across a substantial portion of the panel to enhance the strength of the structure. A strengthening element can be a depression recessing from the second panel wall toward an interior of the panel, a protrusion protruding from the second panel wall toward an exterior of the panel, a rib protruding outwardly toward the exterior of the panel and a trench formed by side walls of adjacent protrusions.

Abstract: A table includes a tabletop and a leg assembly to support the tabletop. The leg assembly comprises first and second supports movably connected to the tabletop. The first support includes a first bar and the second support includes a second bar. The first and second bars are pivotally connected to the first bar. The leg assembly also includes a mechanism for adjusting a height of the leg assembly. The mechanism includes a first coupling piece disposed at the first bar and a second coupling piece pivotally connected to the second bar. One of the first and second coupling pieces includes multiple positioning slots. The other of the first and second coupling pieces is selectively engageable with any one of the positioning slots. Engagement with different positioning slots changes an angle between the first and second bars and consequently changes the height of the leg assembly.
