Abstract: A table with a central extension includes a chassis, two movable trays bearing on the chassis and adapted to be moved closer to each other to constitute on their own one continuous surface, or separated symmetrically from one another, or one independently of the other to allow the set-up of one or several central extension(s) between the movable trays. The chassis is made up of two spars of variable length, two cross-beams, the cross-beams and spars assembled perpendicularly in pairs to form a horizontal frame, and four legs extending at the four corners of the frame below the latter. Each spar includes two portions, a fixed spar and a movable spar, the the spars being made up of a profiled tube with a rectangular cross-section in which extends a slide with a rectangular cross-section and have a longitudinal central groove.

Abstract: A dismantlable table includes a tabletop that is fastened by a fastening component to a structure forming a frame, the structure having a lip that lies flat under the tabletop. Each fastening component includes a latch that is rotatable about a vertical axis, having at least one laterally protruding boss, and includes a recess formed under the tabletop that has at least one protrusion facing the axis. In a mounting position, the bosses pass into the recess next to the protrusions, and in a locking position following rotation, the bosses fit above the protrusions, a lower bearing plane of the latch lying under the lip of the structure.
