A portable cutting apparatus is described. The portable cutting apparatus includes a cutting board having a top surface and a bottom surface. The bottom surface includes sockets configured to receive legs of an elevation system. Each socket is threaded to include an alignment component and teeth. The alignment component biases rotation of the elevation system component during insertion into the socket to enable full insertion. The teeth are configured to mesh with corresponding teeth of the leg and mechanically secure the leg within the socket. The leg is threaded opposite an end configured for insertion into the socket to include a table foot, in a manner that enables individual height adjustment for each leg of the elevation system. The table foot is configured with a hollow cavity that permits articulation of a base of the table foot to adapt to various surfaces when the portable cutting apparatus is deployed.

A table includes a table panel, first and second mounting members, and first and second leg assemblies. Each of the first and second mounting members is coupled or formed with the table panel. Each of the first and second leg assemblies includes a linking member having an end portion rotatably coupled with the first mounting member and another end portion rotatably coupled with the second mounting member. When the first or second leg assembly is unfolded, the linking member abuts one or more retainers of the table panel and forms interference fit with the first and second mounting members. This significantly reduces vibration when the table is in use.

A blow-molded unitary structure includes a panel having upper and lower panel surfaces and a ridge extending downward beyond the lower panel surface. The ridge includes a first side surface, a second side surface, and a lower ridge surface joined with the first side and second side surfaces of the ridge. The ridge further includes a plurality of depressions formed at one or more of the first side surface, second side surface and lower ridge surface. The plurality of depressions enhances the strength of the ridge, and the ridge in turn enhances the strength of the structure.

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 a plurality of depressions, or at least one ridge, or both the depressions and ridge to enhance the strength of the structure. The plurality of depressions is monolithically formed with the panel, recessing from the second panel wall toward the first panel wall. A depression has a side wall composed of first and second segments. Cross-sectional-wise, the first and second segments have different widths and thus collectively forms a step between the first and second segments. A ridge is also monolithically formed with the panel and includes a section, at which the width of the ridge varies along the height direction of the ridge.

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 structure includes a main body, a ridge coupled or formed with the main body and a supporting assembly with a mounting bar disposed adjacent to the ridge. The portable structure also includes a handle coupled to one or more of the ridge, main body and mounting bar by first and second connectors. Each connector includes a first connecting piece connected to the ridge and a second connecting piece coupled or formed with the first connecting piece. The handle includes first and second attachment portions connected to the first and second connectors, respectively, and a gripping portion between the first and second attachment portions to facilitate grasping of the handle.

A large, thin, generally planar panel constructed from blow-molded plastic may include a first surface, a second surface, and a hollow interior portion disposed between the first and second surfaces. The panel may include a nominal panel thickness (PT), which may be the distance between the first surface and the second surface, and a nominal wall thickness (WT), which may be the thickness of the outer wall of the blow-molded plastic structure. A plurality of depressions may be integrally formed in the second surface and a nominal distance (D) separating adjacent depressions may be measured from an edge of one depression to an edge of the adjacent depression. The relationship between the nominal panel thickness, the nominal wall thickness, and the nominal distance between adjacent depressions is shown by the equation WT.Math.PT.Math.D≦0.030.
