Abstract: A table includes a tabletop and a leg assembly to support the tabletop. The leg assembly includes first and second supports each movably connected with the table top. The leg assembly also includes an adjustable bar disposed substantially perpendicular to a height direction of the leg assembly. The adjustable bar has a first end connected with the first support and a second end connected with the second support such that changing a length of the adjustable bar changes a height of the leg assembly.

Abstract: A folding/unfolding mechanism includes first, second and third coupling pieces. Each of the first and second coupling pieces is configured to be fixed at an end of a bar and includes a hole and a slot with a closed bottom and an open top. The third coupling piece includes a slot with closed bottom and top. A first rod passes through the holes of the first and second coupling pieces and the slot of the third coupling piece. A second rod is integrally formed or coupled with a top portion of the third coupling piece, and movable together with the third coupling piece. The second rod is selectively inserted into the slots of the first and second coupling pieces, thereby selectively restricting the rotation of the first and second coupling pieces with respect to each other.

Abstract: Disclosed are sliders, and frames and tables having sliders. A slider includes a sleeve, a pivoting portion and a controller. The sleeve is configured to slidably couple with a first bar, and a first hole and a pillar are formed at a first side wall of the sleeve. The pivoting portion is integrally formed or coupled with a second side wall of the sleeve, and configured to pivotally couple with a second bar. The controller is configured to control movement of the sleeve along the first bar. The controller includes a casing, a lever pivotally connected with the casing, a pin integrally formed or coupled with the lever, and an elastic member selectively pushing the pin into the first hole and a hole of the first bar, thereby restricting movement of the sleeve with respect to the first bar.

Abstract: A table includes a frame and a tabletop coupled with the frame. The frame includes first and second longitudinal bars, each having first and second bars pivotally connected with each other. The tabletop includes a first panel and a second panel. The first panel is coupled with the first bars of the first and second longitudinal bars. The second panel is coupled with the second bars of the first and second longitudinal bars. The tabletop also include one or more first retainers integrally formed or coupled with the first panel and one or more second retainers integrally formed or coupled with the second panel. When the first and second panels are folded onto each other, the first and second retainers engage with each other and lock the table in the folded state.

Abstract: A chair includes a seat, a backrest and a frame to support the seat and backrest. The frame includes first and second supports disposed at first and second sides of the chair, respectively. The chair also includes a first engaging mechanism pivotally coupling the backrest with the first support, and a second engaging mechanism pivotally coupling the backrest with the second support. The first or second engaging mechanism includes first, second and third members. The first member fixedly is coupled with the backrest. The second member pivotally connects the first member of the respective engaging mechanism with the first or second support, thereby allowing the backrest to rotate along a first axis in the width direction of the chair. The third member is fixedly coupled with the first or second support and configured to limit the rotation of the backrest.

Abstract: Disclosed are control mechanisms, frames and tables. A slider includes a sleeve, a pivoting portion and a controller. The sleeve is configured to slidably couple with a first bar, and a first hole and a pillar are formed at a first side wall of the sleeve. The pivoting portion is integrally formed or coupled with the first side wall of the sleeve, and configured to pivotally couple with a second bar. The controller is disposed side by side with the pivoting portion along a longitudinal direction of the sleeve, and configured to control movement of the sleeve along the first bar. The controller includes a casing, a lever pivotally connected with the casing, a pin integrally formed or coupled with the lever, and an elastic member selectively pushing the pin into the first hole and a hole of the first bar, thereby restricting movement of the sleeve with respect to the first bar.
