Definitions

  • the present invention relates to a device for opening and closing a building bay shutter means of the type defined in the preamble of claim 1 and also known from US-A-1 617 771.
  • the blackout shutters such as doors and windows are generally operated by hand to open and close them. In the closed position, they must be held by a suitable lock. In the open position, they must also be blocked to avoid being actuated by the wind.
  • the shutters have a vertical pivot axis, and are folded against the outside face of the wall in the open position, so that the corresponding blocking devices are difficult or dangerous to access.
  • flaps with a horizontal axis located above the bay their opening is made painful by the fact that you have to fight against their weight.
  • DE-A-2,420,178 also discloses a device for opening and closing a means for closing an opening provided in a building ceiling of the skylight type for retractable staircase, comprising a spring constituted by '' a cylinder closed at its two ends, containing a compressed gas and a certain amount of oil, and in which can move back and forth a piston secured to a rod which leaves the enclosure by a tight seal .
  • the rod outlet is in the lower part of the spring to lubricate the seal.
  • the pneumatic spring, or gas, constituted by this cylinder with the compressed gas which it contains and the piston with its rod is connected by one end directly to the periphery of the bay, and, by its other end, by means of obturation through a system of articulated rods.
  • This rod system is arranged so that the open position corresponds to a neutral position, where the spring exerts no torque tending to rotate the shutter means.
  • the object of the invention is to provide a spring device for opening and closing shutter means for building openings which combines the simplicity and robustness qualities of conventional spring devices with the advantages inherent in the gas spring. , namely mainly the possibility of combining a large force with movements at controlled speed and damped at the end of the stroke, and which retains these advantages for a period compatible with the requirements of the building.
  • the air spring is articulated on the lintel of the opening.
  • the air spring is articulated on the closure means and on the periphery of the bay by means of ball joints, which are preferably of the plastic cage type.
  • ball joints which are preferably of the plastic cage type.
  • the dead center mentioned above is that where the straight line joining the centers of the spherical articulations meets the straight line which constitutes the axis of the articulation of the flap on the frame of the opening.
  • at least one pneumatic spring is provided with a position detector which can be connected to means capable of giving the alarm in the event of unwanted opening.
  • This modality makes it possible to dispense with installing special detectors, very visible, and therefore easy to neutralize.
  • the pneumatic spring can be of the lockable type in an intermediate position, and comprising for this a valve which opens or closes the communication between the two faces of the piston, which makes it possible to stop the means of obturation at degree of openness you want.
  • each of the shutters 1 of a window which are articulated by hinges 2 on the window frame, is associated with an air spring 3 filled with gas under pressure and constantly tending to extension.
  • Each of the springs 3 is articulated, on the one hand, in 4 on the shutter and, on the other hand, in 5 on the lintel of the bay.
  • the articulation 4 on the flap is provided on a fitting 6 fixed to the flap, so that this articulation 4 is at a certain distance from the line of the hinges 2 of the flap, line around which the rotation of the latter takes place.
  • the time delay can also be adapted to requirements by adjusting calibrated passages between the faces of the piston.
  • the rod 3a of the piston 3b shown in dotted lines can be hidden by a tube 3c moving telescopically on the cylinder 3d of the spring, in which the piston moves.
  • the pneumatic springs can be of the blockable type in an intermediate position and for this purpose comprise a valve, opening or closing the communication between, the two faces of the piston, which makes it possible to stop the flaps at mid-opening if desired.
  • They can also be associated with a contactor electric triggered in the shutter opening stroke to activate an alarm device.
  • FIG. 5 shows a shutter fitted with the device of the invention and which is of the "projection" type, that is to say that its axis of articulation is horizontal and placed in the upper part of the window frame, while in FIGS. 1 to 4, these were shutters with a vertical axis, these axes being arranged on each side of the opening.
  • the references 1, 2 and 3 respectively designate the flap, the articulation, and the air spring. These parts are shown in dashes in the open position. We can see that the air spring is always oriented with the rod down, which improves its longevity thanks to the oil it contains, and which comes to lubricate the seal, as was said above.
  • the references 4 and 5 designate the articulations connecting the air spring 3 respectively to the shutter 1 and to the window frame.
  • the joints 4 and 5 are ball joints, and in the practical embodiment, these are plastic cage joints, with automatic snap-in for easy assembly, that is to say comprising a trapped ball joint in a cage, which comprises, for retaining the ball joint, a portion of elastic ring of steel or similar material, which is mounted in the housing of the cage where it can slide parallel to the central axis thereof and be further provided with two symmetrically disposed heels, of substantially frustoconical shape, so as to converge towards said axis, said housing having, in addition to the part allowing the above-mentioned sliding of the ring, bearing surfaces for the heels which they prevent them from moving away from each other and releasing the patella.
  • the piston rod 3 is hidden by a tube 3c, which moves telescopically on the 3d cylinder of the spring.
  • This protective tube prevents any deterioration of the piston rod by the effect of shock, dirt, or during the deposition of a layer of paint.
  • the air spring 3 is provided with an electrical position detection device of the type described in patent FR-A-2,571,109 in the name of the Applicant, which is adjusted to close a contact when the elongation of the air spring 3 reaches a value between that which corresponds to the closed position visible in solid lines in FIG. 5, and the open position, visible in dashes in the same figure.
  • FIG. 6 shows the electrical cable for the output of the pneumatic spring at FIG. 6. It can be seen that this cable is not very visible and can in practice be completely hidden behind the fitting 11 which supports the joint 5.
  • Figures 6 and 7 show the detail of a sutomatic locking device of the shutter in the closed position.
  • This device comprises: a plate 12, held by screws 13 against the flap 1.
  • a blocking part 14 is forced to move vertically by sliding on the part 12, thanks to an elongated projection 15 carried by the part 12, and which cooperates with an elongated opening 16 of the part 14.
  • the latter is moreover held by a head screw 17.
  • the lower part of the part 14 comprises an oblique part 18, which cooperates with the fitting 19 carrying the ball joint 4 , so that when the shutter approaches the closed position, a vertical wing 20, perpendicular to the plane of the shutter, and which is part of the lock 19, lifts the part 14.
  • the device which has just been described refers more particularly to the closing of shutters. It is clear that it is also applicable for other uses, such as in particular the opening and closing of window frames.
