Definitions

  • the present invention relates to a retaining device for a door closure system which has as its aim above all to slow down the closure of the door as well as make it gentler in order to prevent it hitting against the frame and also guarantee the closure of said door. It defines a retaining system for door closure with lateral action that functions correctly.
  • the doors of buildings that give out into the street and, in general, the doors of buildings of private estates and communities currently incorporate a device associated with the respective door and the upper part of the frame.
  • This device has the task above all of closing the door passively and also of slowing down the final closure thereof in order to avoid noises and blows.
  • Said device generally comprises a spring housed in a casing, which is tensed via an articulated arm when the door is opened.
  • the accumulated tension of this spring during the opening facilitates the closure of the door afterwards, slowing it down thanks to the choking of a fluid when it passes through a valve incorporated inside the casing.
  • the retaining device for door closure systems constituting the object of the invention is defined on the basis of an oil-hydraulic cylinder with an interior piston integral with a rod protruding from the front end of the cylinder, said piston separating two chambers, a front one where a main helical spring is housed tending to push the piston towards the front and a rear chamber, the piston including at least one joint that is in contact with the inner face of the cylinder in order to ensure the sealing between the two chamber.
  • the piston incorporates a one-way valve with a control mechanism which permits the fluid to pass easily in one direction but blocks it in the opposite direction.
  • the rear end of the cylinder is coupled in an articulated fashion to a rear support integral with a vertical section where a door is coupled by means of the respective hinges, while an end section of the rod has an end piece for coupling, also in an articulated fashion, to a forward support fixed to the door, its position being able to be adjusted in the axial direction.
  • the means of regulation for varying the cross-section for passage of oil in one direction permits us to vary the speed at which the door closes in each of the passage circuits for the liquid mentioned above.
  • a moving piston connected to the rear chamber is an elongated cavity where a moving piston is located acting against the resistance of a smaller spring, a smaller piston which separates a forward space where just the spring and a rear space are to be found connected to the said chamber, with the functioning of the inventive device slowing down the movement of this smaller piston.
  • Means have also been provided for blocking the door in its maximum opening position.
  • the rear end part of the cylinder and the support integral with the vertical section which supports the door assembly incorporate a characteristic blocking mechanism which allows the door to remain open stably when necessary, for example, during everyday tasks such as bringing in the shopping and others.
  • the two chambers are connected together by means of a single exterior conduit in which a valve has been inserted with a control mechanism for being able to regulate the passage of oil between the two chambers, at least in one of the two directions.
  • the said regulating mechanism for varying the cross-section for passage of oil in one direction permits us to vary the speed of closure of the door.
  • the inventive device comprises an oil-hydraulic cylinder 1 inside which is fitted a larger piston 3 provided with a one-way valve 16 which only permits the passage of fluid in a single direction between the two chambers: front 14 and rear 15, separated from each other by the said piston 3.
  • the direction of passage will be from the rear chamber to the front chamber corresponding to the opening of the door.
  • this one-way valve becomes blocked 16.
  • the larger piston 3 is integral with an elongated rod 2 which protrudes towards the outside via the front part of the cylinder 1 and whose end section possesses a thread 17 to which is coupled an end piece 9 that can be axially adjusted thanks to said thread 17.
  • an end piece 9 By means of this end piece 9 the rod 2 of the cylinder 1 is coupled in an articulated fashion to a front support 10 integral with a cross-piece of the door 11.
  • an end piece 9' coupled in the rod 2 is axially adjustable in the direction thereof by means of an intermediate nut 33 coupled in an end threading of said rod.
  • the cylinder 1 possesses a rear end portion 18 in its rear part for coupling in an articulated fashion to another fixed rear support 8 integral with a vertical section 7 where it is connected to the door by means of hinges 6.
  • the two chambers 14 and 15 of the cylinder 1 are connected together by means of two conduits or circuits, a larger one 12 and a smaller one 13, with respective nuts for regulation of the flow 19 and 20 having been inserted between said conduits, and which control the passage of liquid from the front chamber 14 to the rear chamber 15 which corresponds to the oil of the door 10 in order to slow it down.
  • the closure of the door 11 is done passively by means of the action of a main spring 4 which is found within the rear chamber 15, such that during the opening of the door 11 that spring 4 becomes tensed due to its length being reduced when the piston 3 and rod 2 are displaced backwards, while when the closure takes place the tension accumulated in the spring 4 presses and pushes against the piston of the cylinder 1 displacing it towards the front in order to close the door passively.
  • a main spring 4 which is found within the rear chamber 15, such that during the opening of the door 11 that spring 4 becomes tensed due to its length being reduced when the piston 3 and rod 2 are displaced backwards, while when the closure takes place the tension accumulated in the spring 4 presses and pushes against the piston of the cylinder 1 displacing it towards the front in order to close the door passively.
  • the body of the oil-hydraulic cylinder 1 includes a small piston 5 housed in an elongated cavity connected via one end to the rear chamber 15, this small piston 5 separating a front space 22 without fluid where a smaller spring 23 is located and a rear space 21 with fluid which is connected to the rear chamber 15.
  • the rear space 21 of the elongated cavity will fill with fluid due to the increase in its volume against the resistance of the small spring 23, with the reduction in the volume of the front space 22 housing the smaller spring 23.
  • the larger spring 4 reduces its length, thereby storing energy, with the volume of the rear chamber 15 also being reduced.
  • the small piston 15 returns fluid to the rear chamber 15 during closure of the door 11.
  • the rear fixed support 8 incorporates a spring 24 and a ball 25 acting against the resistance of that spring, both elements being housed in a front orifice 26 of the rear support 8, in such a way that said ball 25 which partially protrudes towards the outside, is in contact with a rounded end part 27 of the end portion 18 of the cylinder 1. That rounded end part 18 is equidistant from the point of rotation 28 of the cylinder 1 in such a manner that in the maximum opening position of the door 11, the ball 25 is located in a recess or notch of that end part 27 in order to ensure the stable position of maximum opening of the door 11.
  • the rounded end part 27 includes a small projecting stud 29 which, during the opening of the door, causes the door 11 to become blocked once the stud 29 has exceeded the position of the ball 25 thanks to the fact that said stud 29 meets up against a projecting portion of the ball 25.
  • the stud 29 Prior to the maximum opening of the door 11 and at the start of closure beginning from the maximum opening, the stud 29 momentarily introduces the ball 25 towards the inside against the resistance of the spring 24.
  • the maximum opening of the door 11 can be 90°, though it can also be greater or less than this angle.
  • Figure 6 shows a simpler embodiment in which the two chambers 14 and 15 are connected by means of an intermediate conduit 30 and two end bends 21, with a flow regulator valve 32 having been inserted into that conduit in order to control the passage of oil from the front chamber 14 towards the rear chamber 15 which corresponds to closure of the door 11 in order to slow it down.
