    Abstract: The Play-ble Recreational System is composed of two separate assemblies, each of which includes a through-aperture, dimensioned to allow a beanbag to pass entirely through it, which can be sealed by a detachable cover cap. The invention will be constructed so that the assemblies can serve multiple functions. When the assemblies are separate and distinct, they will primarily be used to play the popular multiplayer game, commonly referred to as cornhole or beanbag toss. However, in addition to this, the underside of each assembly is equipped with collapsible table and game legs, which allows each assembly to become an independent freestanding table. The assemblies also include mechanisms on their front and/or side surfaces that allow the assemblies to be connected together in one of two ways: either perpendicularly to form an L-shaped buffet/serving table, or end-to-end to create a long dinning/serving table that can also be used to play the popular recreational game referred to commonly as beer pong.

  • Patent number: 4583467
    Abstract: A convertible table is comprised of a central planar section and two end sections. The end sections are hingedly secured to the central planar section for rotation thereabout. Each end section has a pair of legs fixedly secured thereto. The legs are not capable of movement with respect to the end sections, but rotate with the end sections.Utilizing the aforementioned approach, a number of table designs are possible. For example, to facilitate folding, the pair of legs attached to one end section may have a greater distance therebetween than does the pair of legs attached to the other end section. In this manner, when the end sections are folded to a position perpendicular to the central planar section, a coffee table, or cocktail table or the like having a lower overall height is formed. The end sections support the central planar section and also form two sides of the table. The legs form the other two sides of the table and may also support the central planar section.
