Definitions

  • a typical door closer for a floor hinge comprises a pneumatic, hydraulic or spring-loaded cylinder housed in a housing being embedded within the floor surface.
  • a piston rod extends towards a hinge shaft of the door, and a cam having a multi-stepped symmetrical cam lobe cooperates with the piston rod on the hinge shaft.
  • An object of the present invention is to provide a door closer in which opening and closing of a door in both directions are under the control of pneumatic cylinders, one for each direction.
  • a further object of the present invention is to provide a door closer including a means whereby the plane of components within the housing can be horizontally aligned with the surface of floor when the housing of the door closure is embedded within the floor.
  • a door closer characterised by a housing arranged to be embedded within a floor to which a door is installed; a vertical hinge shaft extending from the housing; two cylinders, horizontally arranged side-by-side within the housing, each having a piston rod, the piston rods, when extended being positioned one on each side of the hinge shaft; and a V-shaped drive lever connected to the hinge shaft and comprising two legs, each piston rod being arranged to co-operate with a respective one of the legs to close the door.
  • each pneumatic cylinder may have a roller mounted on its end which abuts a respective leg of the drive lever.
  • Each leg of the drive lever may have a concave recess formed at its end, which is engaged by the roller mounted on the piston rod of each pneumatic cylinder when the door is opened at the angle of more than 90°, for example, about 100°.
  • a door closer 10 comprises a rectangular housing 18 which is embedded in a floor 14 such that an upper cover 16 is flush with the surface of floor.
  • a door 12 is installed above the cover.
  • a vertical hinge shaft 20 arranged on one side of the housing 18 is supported by bearings 22, 24; the upper end of the hinge shaft 20 comprises a door connecting plate 26 which is fixedly connected to the bottom of the door 12.
  • the hinge shaft 20 can be freely rotated with respect to the housing 18 when the door 12 is opened and closed.
  • each cylinder has a piston rod 28A, 28B, and these extended towards respective sides of the hinge shaft 20.
  • the pneumatic cylinders 30A, 30B are fixed by brackets 32, 33, 34 to the housing 18.
  • each piston rod 28A, 28B there are mounted respective yokes 36A, 36B.
  • Respective rollers 40A, 40B are rotatively mounted to respective shafts 38A, 38B.
  • Two vertical stops 42A, 42B are mounted on either side of the hinge shaft 20.
  • a V-shaped drive lever 44 is mounted horizontally in the middle of the hinge shaft 20.
  • the drive lever 44 is symmetrical and comprises two legs 48A, 48B, at the front ends of which there are concave recesses 46A, 46B.
  • Each leg 48A, 48B is located toward a respective side of the housing 18 when the door 12 is closed. Abutting the outer surface of each leg 48A, 48B are the rollers 40A, 40B of the piston rods 28A, 28B, when these are extended to their fullest extent from the pneumatic cylinders 30A, 30B ( Figure 1).
  • Each pneumatic cylinder 30A, 30B has equal shape, size and power.
  • a first levelling member 50 is located, extending in the direction of axis of the housing 18 between the two pneumatic cylinders 30A, 30B.
  • a second levelling member 52 extending perpendicular to the first levelling member 50 is located nearby.
  • the housing 18 of the door closer 10 is embedded in the floor 14 before an upper cover 16 is applied.
  • each leg 48A, 48B of the drive lever 44 When the door 12 is closed, the two legs 48A, 48B of the drive lever 44 are each positioned toward a respective side of the housing 18 as shown on Figure 1, and each piston rod 28A, 28B of the pneumatic cylinder 30A, 30B is extended to its fullest extent so that each roller 40A, 40B mounted at its distal end is abutted against the outer surface of each leg 48A, 48B.
  • the piston rod 28A extends by virtue of the accumulated energy of the pneumatic cylinder 30B. This causes the hinge shaft 20 to rotate clockwise, thereby closing the door 12. The other leg 48A of the drive lever 44 rotates clockwise until it abuts the roller 40A of the piston rod 28A.
  • the door 12 remains latched open so long as no closing force is applied to the door.
  • Figure 7 shows the door closer when the door is open in the other direction. It will be understood that the door is operated in the same manner as in the aforesaid explanation.
