Definitions

  • the present invention relates to a hydraulic door closer improved from the point of view of its shape characteristics and which can be advantageously used for the purposes for which it is intended.
  • the door closer which is the subject of the invention occupies little space and comprises several adjustments among which one can mention among others: the adjustment of the closing force; adjusting the slow or fast closing in a place more or less close to the building, and adjusting the slow closing speed.
  • the device comprises a hydraulic chamber inside which is a piston which moves when the door is rotated by means of a pinion connected to one of the control arms of the door closer.
  • the oil in the chamber passes from one side to the other of the piston via a valve associated with the latter.
  • the device further comprises an injector through which the oil passes after opening the door, when it closes under the action of a spring.
  • Said injector comprises a tube provided with radial orifices one being capable of being closed by the valve and the other on which a screw for adjusting the slow closing speed acts.
  • the relative position between the injector tube and the piston regulates the position of the door more or less close to the b8ti in which it must move slowly.
  • a feature of the invention provides for the incorporation of a device for fixing the door in a predetermined position and preferably at 90 °.
  • the door closer which is the subject of the invention incorporates into its body generally a locking element cooperating with a piston locking tooth so that under the action of this locking element on the piston, the door remains held in the predetermined position.
  • both the end of the locking element and the locking tooth have their respective walls inclined so that in addition to making it possible to lock the piston in the position which determines the fixing of the door at a predetermined opening angle, the device allows, by slightly closing the door, to unlock the piston of the locking element.
  • the door closer comprises a general body 1 hermetically closed and inside which is housed a piston 2 and a certain amount of oil.
  • the piston 2 has a few teeth 22 in which the pinion 6 connected to one of the arms 7 of the door closer control, in the manner of a rack, which arm 7 is articulated to the other arm 8 which is for example the one that is fixed on the door frame. Rotating the door determines the rotation of the pinion 6 and thereby the longitudinal displacement of the piston 2 on one side or the other of the internal chamber.
  • valve 9 In the piston 2 is fixed a valve 9 provided with a spring 10.
  • the valve 9 moves along the injector tube 11 which is provided with an axial orifice 12 and radial orifices 13 and 14.
  • the injector tube 11 can adjust its position relative to the piston 2 using the screw 15 which is an integral part thereof. Thanks to this shape, we can adjust the position more or less close to the door frame where the door closes slowly and then goes to a second phase of rapid closing to overcome the latch.
  • the adjusting screw 16 acting on the radial orifice 14 to adjust the slow closing speed.
  • the door is closed by the action of the spring 3 which pushes the piston 2 in the direction of the arrow 18. Due to the oil pressure, the valve 9 moves against the spring 10 by closing the communication passage. Consequently, the oil passes from one side to the other of the piston 2 through the radial orifices 13 and 14 and the central orifice 12 and a rapid closing movement takes place until the valve 9 closes the orifice 13; at this time the oil only passes through the radial orifice 14, which allows slow closing, the speed of which is adjusted by screw 16.
  • the adjustment of the position in which the door passes from a fast closing to a slow closing is determined by the screw 15 which varies the position of the orifice 13 relative to the valve 9, or what which is the same, compared to piston 2.
  • the injector tube 11 comprises between the two radial orifices 14 and 13 longitudinal recesses 19.
  • the general body 1 comprises a housing for a locking element 20 which is mounted so as to be able to act on the piston 2 by means of a spring 21.
  • the piston 2 comprises, in addition to the teeth 22 in which meshes the pinion 6, a locking tooth 23 with which the element 20 cooperates.
  • the locking element 20 retains the piston 2 in a position corresponding to the open position of the door. 90 °, that is to say in the position in which the door remains constantly open in this preset position.
  • the locking tooth 23 and the end of the element 20 are provided with inclined walls 24 which are complementary and allow the action of unlocking or blocking the fixed open position.
  • a small closing rotation of the door causes a longitudinal displacement of the piston 2 in the direction of the arrow 25, and the slippage of the inclined wall 24 of the tooth on the inclined wall 24 of the element 20, which moves against the spring 21, thereby canceling the locking of the door.
  • the piston 2 is locked by the element 20.
  • a free area 26 where the locking element 20 does not act. This area 26 allows the door to pivot by an angle greater than that which is predetermined.
  • the door is normally set to an opening position of 90 °, but any other more open or closed fixed position can be chosen with the articulated arms.
