A liftable table leg includes a bushing, a second fixing piece, a lift assembly, a fixing base and a drive assembly. A first fixing piece is sleeved on a first end of the bushing. The second fixing piece includes a fixing flange and an accommodation groove. The first end is fixed to a bottom end of the accommodation groove through the first fixing piece. A nut of the lift assembly is fixedly disposed at a second end of the bushing. A lead screw of the lift assembly is rotatably disposed in the bushing and threaded into the nut. The second fixing piece is fixedly disposed at the fixing base through the fixing flange. The drive assembly includes a fixing frame. An end of the lead screw is rotatably connected to the fixing frame, and the drive assembly is capable of driving the lead screw to rotate.

A portable workstation apparatus includes: a pair of collapsible legs; and a work portion that is attached in a removable manner to the pair of collapsible lags via a pair of brackets. Each leg of the pair of collapsible legs includes: a frame; an extension connected to a first end of the frame; a lower post housed within a sleeve; an upper post; a hinge connecting the lower post and the upper post; a first brace connecting the extension to the sleeve; and a plurality of holes on an exterior face of the lower post or the upper post. Each leg is configured to collapse by folding the upper post towards the lower post via the hinge and rotating the extension toward the lower post.

Disclosed is an assembly-friendly table frame, which relates to the field of lift tables. The table frame includes an upright and a base stand mounted to the underside of the upright; one of the base stand or the upright is securely coupled with a connecting member, and the other thereof is provided with a locking bump; the connecting member includes an insert-fitting rail and a locking slot provided in the insert-fitting rail; the locking bump is sequentially inserted into the insert rail and slid to be snapped into the locking slot; the table frame further includes an ejector member configured to eject the locking bump out of the locking slot. Further disclosed is a table applying the table frame. An advantage of the present disclosure lies in enhancing convenience of assembly and disassembly between the upright and the base stand.

A support arrangement (1) for an object (2), comprising primary frame (10), at least three pivoting members (21, 22, 25) and first, second, third and fourth feet (31, 32, 33, 34) fixed to the three pivoting members. The primary frame includes longitudinally spaced first and second stem portions (11, 12) fixed to a longitudinal member (13). The first and fourth feet are laterally spaced and positioned towards a first end of the primary frame and the second and third feet being laterally spaced and positioned towards a second end of the primary frame, the second and third feet being longitudinally spaced from the first and fourth feet. At least one interaction arrangement (50) provides interaction between the three pivoting members such that the four feet can move to accommodate or engage an uneven surface while maintaining control of the object in a position parallel to the average ground plane.

A table frame for a table has a first column and a second column for supporting a table top, a cross member of hollow profile construction by which the first column and the second column are interconnected with each other and a first cantilever support mounted on the top end of the first column and a second cantilever support mounted on the top end of the second column. The first and the second column each have two projections at respective top ends thereof. The cross member, at each end section thereof, has a pair of oblong holes disposed on its lower side and through which the two projections of the respective column extend into the cross member. Each cantilever support has a first and a second flange which are arranged spaced-apart from one another, each of the flanges abutting the cross member on a lateral side portion thereof.

A projectile-resistant table provides a reduced weight by employing separate structures for table stiffness and projectile resistance, for example, using a sandwich structure composite with high stiffness and tow projectile resistance for table integrity and a flexible fiber mat with low stiffness but high projectile resistance for shielding.

A tabletop assembly, a lifting frame assembly and a height adjustable table are disclosed. The assembling operation of the height adjustable table is simplified by using a supporting part rotatably connected to a table board support and a first terminal block and a second terminal block which are arranged in pairs. During transportation, the height adjustable table may be disassembled into a tabletop assembly and a lifting frame assembly to be packaged and transported, respectively, thus reducing the size of the package. Meanwhile, the lifting frame assembly may be folded, the second terminal block on the lifting frame assembly in a folded state forms an approximate fan-shaped region with the table board support, so that the second terminal block may be protected during transportation. After receiving the goods, the consumer may assemble the tabletop assembly and the lifting frame assembly through a simple process.

A flip-top table has a tabletop attached to a frame through a pivoting assembly. The tabletop is made from a ballistic-resistant material allowing it to be used as a ballistic shield when it rotates from its horizontal working position to a vertical shielding position. A front modesty panel is also ballistic-resistant and is mounted between the front legs of the frame. A lift speed restrictor is connected between the tabletop and the frame which prevents the user from lifting the tabletop too quickly which could topple the table, and it includes a biasing mechanism that provides a lifting force and helps to hold the tabletop in the shielding position. The table also includes visual indicators that readily indicate to persons around the table that the table can be converted into a ballistic shield. Casters allow one or more tables to be quickly moved and repositioned into a defensive arrangement.
