Definitions

  • the present invention relates to a double action door closer intended in particular to ensure the automatic closing of doors which can open in two directions of rotation, this door closer comprising a pivot whose rotation is linked to the movement of the door and a rotary lever control device connected to a return spring and to a shock absorber.
  • document DE-A-1 961 945 describes a double action door closer having the characteristics set out in the preamble of claim 1.
  • the pivot meshes with two parallel racks facing each other, a spring return being trapped between stops integral with the two racks and a damper being arranged in the extension of the spring.
  • These door closers have the disadvantage that they necessarily have a significant length.
  • the spring being directly crushed at its two ends by the stops, racks, an adjustment of its crushing is practically impracticable.
  • the object of the invention is to provide a double action door closer having a reduced size, both narrow and short in length, and easy to adjust.
  • a double action door closer of the type comprising a pivot whose rotation is linked to the movement of the door and a control device comprising a damper and a return spring, said pivot permanently meshing with two parallel racks facing each other, characterized in that selective connecting means are provided which, for each direction of rotation of the pivot, secure one of the two racks with the control device during the opening stroke and separate this rack and said control device at the end of the closing stroke.
  • one of the racks is secured to the control device in one direction of opening of the door while it is the other rack which is secured to this device in the other direction d door opening. Furthermore, in the case where it is sought to cause the door to close at a speed greater than the preset speed of the core provided by the control device, as the latter is secured to one of the two racks, the damper of the control device can play its side and slow down the movement of this around the door.
  • the thickness of such a door closer can easily be made sufficiently small to allow the door closer to be inserted into a profile constituting a door.
  • the selective connection means comprise an oscillating lever carried by the control device and having a hook normally located on the paths of a projection of each rack, the housing of the door closer comprising a stop attacked by the lever oscillating at the end of the closing stroke to move this hook away from said trajectories.
  • the selective connecting means comprise a movable element which crosses with play a longitudinal rod of the control device and reliefs of each rack which laterally move the movable element towards the other rack to secure this element with this other rack when the pinion turns in the corresponding direction.
  • the door closer 1 shown in Figs. 1 to 4 has three parts, namely, from left to right considering FIG. 1: a pivot-rack assembly 2, a connection assembly 3 and a control assembly 4.
  • Each assembly 2 to 4 is housed in a housing 5 to 7 respectively, these housings fitting into one another to constitute after screwing the door closer housing.
  • This casing has a generally parallelepiped shape, the thickness e (Fig. 2) is small enough to accommodate the door closer in a door profile.
  • the assembly 2 comprises a pivot 8 of vertical axis XX freely rotatable in the housing 5 but axially fixed.
  • the intermediate part of this pivot forms a pinion 9 which meshes with two rectilinear racks 10 and 11 which each slide against a side wall of the housing 5 and which form the reflected image one the other.
  • each rack carries a horizontal pin 12 directed towards the other rack.
  • the pins 12 are in the extension of one another, and the ends of the racks are contained in two vertical planes perpendicular to the vertical plane of symmetry P of the door closer.
  • the housing 6 of the connection assembly 3 has a central passage 13 of rectangular section in which slides a piston 14 parallelepiped.
  • the upper wall of the passage 13 has a longitudinal groove 15 in which a flexible blade 16 is fixed.
  • the left end of the latter is folded down to define a short stop 17, and its right end, which has a capacity for movement vertical, has a rounded recess 18.
  • the blade 15 is fixed by screws in its left part, and a rotary cam 19 with horizontal axis makes it possible to adjust the height of a part of this blade located between these screws and the recess 18 .
  • the left end of the piston 14 carries a transverse axis 20 on which is mounted for a lever 21 in L with two arms.
  • a lever 21 in L with two arms.
  • an arm 22 In the rest position (Fig. 1), an arm 22 is retained by the stop 17 in the vertical position; the other arm 23 projects horizontally to the left out of the piston 14, and a hook 24 directed downwards, which forms the end of this arm, is situated above the common horizontal plane of the pins 12.
  • the control assembly 4 comprises a rotary lever 25 with a horizontal axis, one arm of which is connected to an adjustable compression spring 26 and the other to a hydraulic damper 27 also adjustable, with piston 28.
  • This assembly 4 is conventional; it will therefore not be described in more detail and is shown diagrammatically.
  • Two parallel connecting rods 29 are articulated by one end to an eccentric horizontal axis 30 carried by the lever 25 and by the other end to a horizontal axis 31 mounted in the right end of the piston 14.
  • the axes 20 and 31 and the pins 12 are parallel and contained in the median horizontal plane Q of the door closer.
  • the control assembly 4 and the piston 14 form the control device for the door closer.
  • the pivot 8 rotates clockwise according to the arrow f (Fig. 4) by carrying with it the rack 10, which slides to the right, and the rack 11, which slides in the opposite direction. Under the effect of this sliding, the rack 10 directly pushes the piston 14, which also slides to the right.
  • the connecting rods 29 then rotate the lever 25 in the clockwise direction of the arrow g (Fig. 3), which causes on the one hand the compression of the spring 26 and on the other hand the displacement to the right without significant hindrance of the piston shock absorber 28 in its cylinder.
  • This opening movement is limited by the stop of the rack 11 against the left end wall of the housing 5.
  • the damper 27 may comprise, as known, an oil pressure limiting device which in such a case allows an increase in the speed of displacement of the piston 28.
  • the damper 27 can also be provided with means allowing the abrupt acceleration of the movement at the end of the closing stroke, in order to guarantee the complete closing of the door and, in particular, the engagement of the lock of this door. .
  • the piston 14 is always integral with the rack which moves to the right, thanks to the hook 24, whatever the direction of opening of the door.
  • the blade 16 can serve not only as a stop for the lever 21 but also as a device for holding the door in the open position or "door stop". In fact, when the cam 19 is retracted, the blade 16 does not interfere with the trajectory of a ball 32 carried by the piston 14. However, if desired, the cam 19 can be given an angular position in which it pushes down the right part of the blade 16. In this case, the recess 18 snaps resiliently at the end of the opening stroke on the ball 32, which constitutes the door stop.
  • Figs. 5 and 6 show a variant of the selective connection device between the racks 10 and 11 and the piston 14.
  • the lever 21 is replaced by a longitudinal rod 33 which extends the piston 14 to the left and is rigidly fixed to that -this.
  • a ball 34 freely passes through a hole 35 provided at the end of the rod 33.
  • Each rack has at its right end a block 36 projecting towards the other rack, the spacing between the two blocks being less than the diameter of the ball 34.
  • the left end of each block 36 is hollowed out by a recess 37 with vertical generatrices and with a rounded bottom 38.
  • the ball 34 is opposite the two recesses 37, which hold it in the hole 35. Under the effect of the movement to the left of the rack 11, this ball 34 is pushed towards the rack 10 by the bottom 38 of the recess 37 of the rack 11 and is housed at the bottom of the recess 37 of the rack 10, which secures the piston 14 with the rack 10 moving to the right.
  • the door closer and its operation are identical to what has been described above with reference to FIGS. 1 to 4.
  • the ball 34 can be replaced by a movable element of an appropriate shape other than a spherical one, for example making it possible more quickly to secure the piston with the rack at the start of opening.
