Adjustable folding table

Abstract

This utility model discloses a type of adjustable, folding table, composed of a table top and a table frame, wherein the table frame comprises two cross bars, at least two longitudinal bars, two leg sets, and two support rods, and wherein the table top comprises two fastened and joined main table tops and at least one auxiliary table top. The bottom of each table top is shaped to have sliding grooves corresponding to two crossbars. The two main table tops of this folding table slide relative to the two cross bars of the table frame. Therefore, when it becomes necessary to increase the area of the table top, one can move the two main table tops relative to the cross-bars towards the two sides, join the auxiliary table tops between the two main table tops, and set them on the cross-bars to form a table top with a large surface area. When it becomes necessary to reduce the size of the table top, then one needs only detach the auxiliary table tops. After this folding table has been folded, the auxiliary table tops can be fastened to the underside of the main table tops, without having to take up excess volume. Thus, it is easy to use and quite practical.
