Definitions

  • the present invention relates to a machine for striking floor coverings constituted of geometrical figures, in order to improve their planimetry and adherence, having, mounted to be integral on a chassis whose dimensions are clearly greater than those of said geometrical figures, a base composed of striking elements that may render the chassis horizontally movable over the floor.
  • Machines which are intended for mechanizing this work and which are constituted of a chassis whose dimensions are clearly greater than those of the figures to be placed in position, on which is fixed a base, provided with striking elements, for example rollers, balls, juxtaposed rubbered rollers.
  • a motor fixed to the chassis rotates a member which transmits a periodic movement of percussion to the base.
  • a machine for striking floor coverings constituted of elements forming geometrical figures, in order to improve their flatness and adher ence, said machine having, mounted integral on a chassis whose dimensions are clearly greater than those of said geometric figures, a base composed of striking elements which are also capable of rendering said chassis horizontally movable over the floor, characterized in that it comprises, fixed to said chassis, a device comprising at least one hammer drawn by an electromagnet and returned to its original position by at least one spring, said hammer periodically vertically striking an element integral with said chassis.
  • the devices comprise for example one or more electro-magnets disposed on the chassis, the coils being fixed to said chassis and the movable elements striking the cores of said coils.
  • the role of the bridge in the form of hammers of the first example cited is played by the moving elements of the electro-magnets, each of said moving elements constituting a hammer.
  • a bridge 7 constituted by a central body 8 and two lateral ends 9 and 10 is mounted to be integral with the chassis 3 by means of the rods 11 fixed by one of their ends to the chassis 3 and rendered integral with the bridge but nuts 13.
  • These rods have moreover seats 12 and 14 between which are compressed elastic means, for example constituted of a helical spring 15.
  • the rods 11 slide in a sleeve 16 so as to allow the elastic means to play freely when the bridge moves towards the framework.
  • the ends 9 and 10 of the bridge 7 are arranged in the form of hammers l7 and are placed opposite one another on the periphery of the chassis so that the elements 17 strike the elements 18 integral with said chas- SIS.
  • the electro-magnet is 'used according to its power curve, for a value of its air gap giving a maximum force which will be constant if the distance of said air gap is adjusted once and for all.
  • This force will of course be chosen to be higher than the resistant force of the elastic means during the feed of the coil when the bridge moves towards the chassis.
  • the distance of the air gap may be adjusted by means of ferromagnetic members 22 fixed by 20 between the coils and the frame, according to the power curve of the electromagnet used.
  • a machine for striking floor covering is thus obtained which is simple, robust and manageable, adapted to the covering used and with a high yield which, in the exampie described, is of the order of sq. m. per hour.
  • Machine for striking floor coverings constituted by elements forming geometrical figures, for improving their planimetry and adherence, composed of a chassis whose dimensions are clearly larger than those of said geometrical figures, which chassis comprises two lateral stringers, a bridge disposed transversely to said chassis having the general form of a reversed V, means for abutment on the floor fixed to said lateral stringers, these means enabling said coverings to be struck and the said chassis to be rendered horizontally movable over the floor, of at least one electro-magnet composed of coils and moving elements, said coils being fixed to said chassis, and said moving elements being integral with said bridge on whose ends two hammers are disposed, which strike vertically and periodically each of said stringers and of at least two helical springs disposed between said chassis and said bridge in order to return this latter to its original position.
  • Machine as defined in claim 1 comprising means for adjusting the air gap of said electro-manget.
