The present invention relates generally to tables and chairs. More particularly, the present invention relates to a locking mechanism and a stabilization mechanism for a table or chair configured to keep the table or chair stable and prevent from rocking and tipping over if weight is applied to the edge of the table.
Tabletops, especially those associated with tables used in restaurants and other commercial outlets, are ideally stable such that articles placed on a tabletop thereof remain steady. However, based on a myriad of factors such as uneven surfaces, ground warping, and material warping, tables and chairs tend to rock back and forth, which is very disruptive for those seated thereabout. Solutions including the placement of folded paper under one leg of the table, which is simply ineffective and inefficient.
An exemplary solution is described in U.S. Pat. No. 9,414,676 to Eddie Raffi, entitled “Table and chair with self-stabilizing system” which discloses an integral system for stabilizing a table on an uneven surface. The table comprises a tabletop supported by a first end of a primary shaft, a second end of said primary shaft having a first pair of legs extending therefrom, a secondary shaft positioned within, and movably joined at a first end to, said primary shaft, a second end of said secondary shaft having a second pair of legs extending therefrom, wherein said secondary shaft may move in a side-to-side, rocking manner relative to the primary shaft thereby stabilizing the table.
Another exemplary solution is described in U.S. Ser. No. 10/342,328B2 to Eddie Rafi that describes an integral system for stabilizing a long table on an uneven surface. One version includes two spaced supports with each of the supports comprising a vertical member. One horizontal platform attaches to an upper portion of one of the supports and an underside of the tabletop and a second horizontal platform affixed to a post and attached to the underside of the tabletop. The post is insertable into the vertical member of the other support and movably joined at a first end thereto such that the post may move side-to-side, in a rocking manner relative to the vertical member stabilizing the table.
There is a need for a system to further stabilize tables and chairs that utilize non-rocking technology that are operable with tables of many different shapes and sizes, thereby preventing them from rocking and tipping over if weight is applied to the edges.
