Definitions

  • Hydraulic mechanism for door opening of the kind fixed to a structure, such as a wall, frame or floor of the type comprising a base with two covers between which covers the door is fixed by securing means, characterised in that it comprises: an eccentric shaft, a first piston, connected to at least one spring and to the eccentric shaft and a closed circuit with lubricant fluid or oil that moves in function of whether the referred spring is compressed or decompressed, thus regulating the door-opening or closing speed.
  • Utility Model No 0274475 "MECANISMO HIDRAULICO MEJORADO PARA EL CIERRE DE PUERTAS”, of 1985, also belongs to the inventors, which refers to an improved hydraulic mechanism for closing doors, of the type that successively produces a first, second and third door-closing speed, which is housed inside a covered box that contains a fluid and arranged in a floor cavity and level with it and which comprises a hydraulic pump geared to discs firmly attached to a rotating shaft protruding from the box and linked to the lower corner of the door articulation, with this frame being able to move forwards or backwards according to the rotation direction and with the door being fitted with springs that tend to maintain it in a position that corresponds to the closing of the door, maintaining the pump piston retracted, essentially characterised in that the hydraulic pump is fitted with the means to leave the third closing speed activated or deactivated and in that the box and cover, obtained by moulding plastic material, contains complementary elements to constitute the stop of the cited springs, the
  • Hinged mechanisms are also known that have an eccentric shaft that is firmly secured to covers that fix the door with screws or similar elements and, when closed, are fixed in a given position because of the eccentric shaft and the same happens on opening.
  • This application is associated with the door-opening mechanisms sector, which are fixed to a wall or frame.
  • This hinge does not regulate the door-opening and closing speed because the hinge suddenly changes position due to the force of a person pushing it.
  • the first two utility models provide solutions to this problem.
  • the only drawback is that they require a complicated installation process and, at the same time, they do not regulate that at the door opening moment, it must move faster because the person is pushing it and must move somewhat slower to ensure it does not strike the person passing through.
  • This Utility Model resolves the speed-regulation problem on closing the door.
  • installation size is only slightly larger than that of the glass door to which it is fitted, so that it is visually hidden and aesthetically acceptable.
  • One object of this invention is a hydraulic mechanism for door opening of the kind fixed to a structure, such as a wall, frame or floor of the type comprising a base with two covers, between which covers the door is fixed by securing means, characterised in that it comprises: an eccentric shaft, a first piston, connected to at least one spring and to the eccentric shaft and a closed circuit with lubricant fluid or oil that moves in function of whether the referred spring is compressed or decompressed, thus regulating the door-opening or closing speed.
  • Figure 1 illustrates base 8, covers 9, fixing means 10 and eccentric shaft 1.
  • Figure 5 represents eccentric shaft 1 with bushing 3 and axial bearing 6, second piston 21 with second spring 22, third spring 26, base 8, first piston 2, first chamber 4, first spring 24, non-return valve 16 and connection 28.
  • eccentric shaft 1 When a person pushes the door to open it, eccentric shaft 1 rotates and pushes first piston 2 and first spring 3 and second spring 12 downwards, compressing the space in oil chamber 4, which forces the oil upwards inside second spring 12 and through non-return valve 5, filling tube 7.
  • eccentric shaft 1 rotates again, but no longer pushes first piston 2 and springs 3, 12 return to their original positions. Then, a vacuum is produced in oil chamber 4, which is filled with oil from tube 7 and dispensed by flow-rate regulator 6. The oil must follow this route because non-return valve 5 prevents the oil from circulating in the opposite direction.
  • the door-closing speed will be higher or lower.
  • eccentric shaft 1 rotates and pushes second piston 21, compressing second spring 22 and third spring 26 against the second cover of spring 23.
  • eccentric shaft 1 rotates and stops first piston 2 from pushing on first spring 24 allowing first spring 24 to decompress.
  • eccentric shaft 1 is double because it contains two eccentric elements at the same time, one for first piston 2 and one for second piston 21, so that completely opposite effects are produced on the springs.
  • first piston 2 movement of the oil or other lubricant fluid is produced and moves inside a circuit.
  • first regulator 29 and second regulator 30 supply oil inside tube 7 and to first chamber 4.
  • Non-return valve prevents 16 prevents the oil from being transferred from first chamber 4 to second chamber 31 via connection 28.
  • double eccentric shaft 1 rotates again and compresses first spring 24 and decompresses second spring 22 and third spring 26.
  • first piston 2 produces the opposite effect, first spring 24 is compressed and reduces the space in second chamber 31.
  • An oil transfer then occurs from second chamber 31 to the first chamber 4 via non-return valve 16.
  • oil is supplied to second chamber 31 via regulators 29 and 30 at a lower flow rate than that transferred from second chamber 31 to first chamber 4.
  • Said regulators 29, 30 can be calibrated so that they establish the door opening and closing speeds.
