A foldable chair, comprising a seat portion and a telescopic side wall includes rings of varying diameters consecutively arranged. A topmost ring is mounted to a bottom surface of the seat portion and has a smallest diameter. A bottommost ring has a largest diameter. In deployed position, the telescopic side wall is opened or partially folded to set and lock a desired height of the chair. In fully retracted position all of the rings are disposed adjacent the bottom surface of the seat portion. Each ring is an integral unit configured with a locking arrangement that selectively locks it to an adjacent ring. In some embodiments, a security lock centrally disposed along a height of the chair substantially perpendicular to the varying diameters of the rings secures the locking arrangement. A table uses the foldable chair as a leg and can store several, for example four, foldable chairs.

A collapsible tray table is provided. The collapsible tray table is adapted for use in confined seating situations. The collapsible tray table is movable between a collapsed condition and at least one operable condition. The collapsible tray table may have one or more tray legs and one or more second leg portions that depend from a tray top. The tray legs and second leg portions are interchangeable for providing different operable conditions and thus elevations of the tray table relative from its footing. The tray legs and second leg portions are adapted to removably connect to the underside of the tray table in a collapsed condition, thereby minimizing the low profile of the assembly in crowded seating arrangements. The collapsible tray table may provide handles and a carrying strap for facilitating transportation and manipulation of the tray table while in use.

A splicing metal plate includes at least one pair of an elongated first and second connecting plate, the elongated first connecting plate having a side edge that extends downwardly vertically with an accommodating portion having an opening, the elongated second connecting plate having a side edge that extends downwardly vertically with an embedded portion, and the accommodating portion of the first connecting plate is embedded within the embedded portion of the second connecting plate. A front-end cover connected to a front-end of the first and second connecting plates along a length direction. A rear-end cover connected to a rear-end of the first and second connecting plates along the length direction. A supporting portion for the front-end and rear-end covers disposed at bottom portions of the first and second connecting plates.

A device may include a slat defining a planar surface. A device may include a first leg including: a leg segment with a predominantly planar portion. A device may include a spring tab on a first longitudinal end of the leg segment, the first leg being pivotably coupled at the first longitudinal end of the leg segment to the slat. A device may include a second leg pivotably coupled to the slat. A device may include an alignment shaft configured to be coupled to the slat, the spring tab being configured to be coupled to the alignment shaft via a friction fit as the first leg is rotated to an open position.

A foldable table may include a tabletop and legs that are movable between an extended position and a collapsed position. The tabletop may include a first section and a second section that are connected by a hinge assembly. A locking mechanism may be sized and configured to lock the hinge assembly in a fixed position. The locking mechanism may include a locking member, and the locking member may be a unitary, one-piece structure. The locking member may be rotatably connected to a connector of the hinge assembly. The locking member may be connected to a locking structure that is movable between a locked position and an unlocked position. The locking member may be sized and configured to bias the locking structure into the locked position.

A portable sand table, including a body including a top surface and a raised border disposed along a perimeter of the top surface, a plurality of hinges disposed at a bottom surface of the body to allow the body to fold in half, a plurality of removable legs to extend perpendicularly from the bottom surface of the body, and a plurality of leg storage portions disposed at the bottom surface of the body to store the plurality of removable legs therein when the removable legs are removed from the bottom surface of the body.
