The portable table described herein includes: hubs respectively installed at front left, front right, rear left, and rear right corners of the table; four frames separably connecting to the hubs to form a four sided table top; front left, front right, rear left and rear right leg frames, each respectively having base ends separably coupled to the surfaces of the respective hubs and respectively having free ends disposed in a manner extending toward the ground surface; and a top sheet coupled to the support frames forming a table top with four leg frames. The leg frames may be of differing length to position the table in a more level position when placed on a non-level surface. The structural rigidity is excellent, and the table may stand on a surface in a stable position.

Disclosed are adjustable bars and structures having adjustable bars. An adjustable bar includes an inner bar, an outer bar and a locking/unlocking mechanism to control relative movement of the inner and outer bars. The locking/unlocking mechanism includes a locking pin to be selectively inserted into a restriction hole of the outer tubular bar and a restriction member of the inner bar, thereby selectively restricting relative movement of the inner and outer bars in at least one direction. The locking/unlocking mechanism also includes a feature to prevent accidental release of the locking pin from the restriction member. Structures having such adjustable bars are easy and safer to use.

Stowable workstations are provided which have back, top and front panels and side pillars and are configurable in a stowed configuration wherein the panels and side pillars form a rectangular enclosure and which can transition to a deployed configuration wherein the front panel extends horizontally to form a desk surface.

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.
