  • Each leg is comprised by a stanchion, to the upper end of which is connected as an integral part a first vertical bracketwwhich is in turn pivotally connected to a second similar vertical bracket, the pivot axis between said two brackets being concentric with the axis of the stanchion so that said second bracket can perform swinging movements with respect to the first bracket through an angle of about 90.
  • said second bracket which is movable relative to the first one, can attain two limit positions, i.e., a first operative position wherein it is set at an angle of about 90 to the first stationary bracket, where it constitutes in combination with this latter a two arm supporting means for one of the corners of the board carried by the legs, and a second inoperative position, wherein the movable bracket has been turned against the first stationary bracket.
  • the first bracket is pivotally connected to an angle member around a pivot axis which is horizontal and parallel to one of the'sides of the upper board to which said member is fixed by means of screws or the like.
  • the hinge means provided between the first bracket and said angle member is so positioned and spaced apart from said board that, as the second bracket has been turned into contact with the first bracket both said brackets together with the stanchion can be turned against the lower surface of the board of the table. Further locking means are provided to hold the parts in their folded and unfolded positions as well as to limit the swinging movements of the parts.
  • the parts forming the table are firmly locked to each other so that the table acts as it would be constructed in a single body. Further the operations to, be performed to fold and unfold the table are simple and do not require the use of any tool so that also an unskilled person is able to accomplish said folding and unfolding operations.
