A sport training structure includes a plurality of brackets and a plurality of first pivot members connected with the brackets. Each of the first pivot members has two connecting portions. Two of the first pivot members are mounted between two of the brackets to construct a polygonal frame, with each of the two connecting portions of each of the first pivot members being pivotally connected with one of the two pivot ends of each of the brackets. In such a manner, the two of the brackets are pivoted about the two of the first pivot members, so that the polygonal frame is foldable.

A transformable table includes a base, a transformable platform mounted on the base, a lifting mechanism that drives the transformable platform to move up and down, and an interlocking member that draws the transformable platform to pivot. Thereby, the up and down movements of the lifting mechanism can make the transformable platform pivot accordingly so that the surface of the transformable platform can be selectively posed at different angles required by different applications, thereby allowing the transformable table to be used with versatility.

A vehicle tonneau cover includes a first tonneau cover portion and a second tonneau cover portion positioned opposite the first tonneau cover portion. A connecting structure connects the first cover portion with the second cover portion. A third tonneau cover portion is coupled to the connecting structure so as to be securable in a first position to form a first configuration of the cover, and in a second position to form a second configuration of the cover. In the first configuration, the third cover portion resides between the first and second cover portions. In the second configuration, the third cover portion is spaced apart from the first and second cover portions so as to form a first gap between the third cover portion and the first cover portion and a second gap between the third cover portion and the second cover portion.

An expandable table assembly includes a box that is positionable on a support surface to serve as a coffee table. A lid is hingedly coupled to the box for closing the box. A top surface of the lid is horizontally oriented when the lid is closed to serve as a table top. The top surface of the lid is oriented at an upwardly slanting angle when the lid is in the open position to serve as an angled work surface. A first extension panel is hingedly coupled to the first lateral side of the box and a second extension panel is hingedly coupled to the second lateral side of the box. Each of the first and second extensions panel extends away from the respective first and second lateral sides in a horizontal orientation when the first and second extension panels are positioned in a deployed position thereby increasing a surface area of a top of the box.

A pool table has a removable dining surface and a gravity-based ball-return system located transversely between end legs of the pool table. Balls that have been pocketed during a game on the table's playing bed are commonly collected in one of inclined two gullies that connect together multiple pockets. The gullies are peripheral to the table and directly beneath pockets that are, preferably, either side of a central longitudinal axis of the table. The ball return system includes a stacked arrangement of runners that receive a pocketed ball from a cascading drop at the end of each gully. Once into the stack, a ball separation device identifies and selectively separates a cue ball from object balls, with the cue ball directed downwards towards a free-return box while object balls are directed along a different downward path. Object balls are then retained behind a ball retainer and release mechanism which, when in a release position, causes delivery of all object balls to a ball picking slot at an end of the pool table common with the free-return box. Pool table depth is therefore minimized while space under the table's bed is maximized to accommodate seating.

A table assembly includes a tabletop member having a tabletop worksurface and a downwardly directed lower surface. A leg structure including first and second substantially vertical and spaced apart leg members is coupled to the lower surface for supporting the tabletop member. An elongated horizontal upper member extends between upper ends of the leg members. An elongated horizontal lower member below the tabletop member lower surface extends between and is joined to the leg members intermediate their upper and lower ends to form a gap with the upper member. A removable accessory bracket includes a substantially flat vertical member extending along a first plane and a lip member coupled to an upper end of the vertical member, the lip member extending along a second, substantially parallel plane spaced from the first plane and engaging the lower member to support the accessory bracket adjacent the outer surface of the lower member.
