Definitions

  • the present invention relates to an anti-vibration double glazing, of the type comprising at least two panes separated by a space, see for example DE-A-3205312.
  • the purpose of the present invention is therefore to make these double glazing more efficient in their anti-vibration functions.
  • an anti-vibration double glazing is mainly characterized in that at least part of a wall delimiting this space is mobile and is connected to motor means controlled by a servo system receiving at its input a signal representative of the pressure in said space or of the movements of one of said panes, said servo system being arranged to control movements of said movable part such that they tend to keep the pressure in said space constant.
  • the response time cannot of course fall below a certain threshold, fixed by the dimensions of the panes and by the speed of sound in the gas occupying the space which separates them.
  • Such double glazing can also be characterized in that said movable wall portion is constituted by a flexible or rigid membrane, at the same time ensuring the seal between said space and said motor means.
  • These motor means will advantageously comprise at least one linear electric motor of the variable reluctance type with double magnetic circuit, for example of the type described in French patent n ° 91 14576 in the name of the applicant.
  • motors comprise, as a movable member - which will therefore be connected to said membrane - a plate of laminated magnetic material, interposed between the two magnetic circuits, the coils of which will be supplied alternately. Depending on whether one or other of these windings will be powered, the movable member of the motor, and therefore the membrane, will move in one direction or the other, to increase or decrease the volume of said space provided between the panes .
  • the excitation currents will have a maximum value at low frequencies.
  • one or more elastic masses of determined stiffness are interposed between moving parts and fixed parts, it being understood that the "moving parts” denote what has been called above the “moving wall part” as well as the moving parts of said motor means or the parts thereof and that the fixed parts designate the structure of the double glazing and all that is attached to it.
  • a "rigid membrane” connected to the fixed structure by an elastomer ring or the like; a similar ring can also be interposed between the fixed structure and the periphery of the sheet of laminated magnetic material of the motor, in order to obtain the desired overall stiffness between the moving parts and the fixed parts, and thus achieve optimum operation of the motor means. at the frequencies considered.
  • the input of the servo system can be connected to an internal or external pressure sensor, or to a displacement sensor or accelerometer linked to the glass that emits vibrations.
  • this double glazing may be characterized in that said motor means and said movable wall part form part of a housing suitable for being fixed in a housing of said frame, which will facilitate manufacture and maintenance.
  • the chassis 4 comprises a housing, for example of cylindrical shape 7, in which is fixed, by means of a screw 8, the body 9 in the form of a housing of a variable reluctance motor comprising two magnetic circuits 10 and 11 equipped respectively with two windings 12 and 13 and between which is disposed a plate of laminated magnetic material 14, integral with a guide rod 15 carrying at its end a rigid membrane 16, which constitutes what has been called above the "movable wall part "suitable for modifying by its movements the volume of the space 3 formed between the two panes.
  • Elastomer rings or the like, respectively 17, 18 and 19 are bonded between the rigid membrane 16 and the body 9 of the variable reluctance motor, between the plate of laminated magnetic material 14 of the motor and this same body 9, and finally between this body and the end of the guide rod 15 opposite to that which carries the movable wall 16.
  • these rings thus make it possible to seal between the space 3 and the motor means and to subject the movements of these means to an antagonistic spring effect whose stiffness can be perfectly determined and adapted to the operating conditions of the variable reluctance motor.
  • the coils 12 and 13 of this motor can be supplied with current, respectively I1 and I2, in a control loop such as that which is shown by way of example in FIG. 2, in which the references 20 and 21 denote respectively a corrector circuit and a linearizer circuit, and the reference 22 an operator receiving on its input 23 a zero pressure variation instruction and on a second input 24 a signal representative for example of the pressure in space 3, which can be measured for example by a pressure sensor shown diagrammatically at 25; the loop 26 therefore transmits to the operator 22 this signal representative of the pressure in space 3.
  • a control loop such as that which is shown by way of example in FIG. 2, in which the references 20 and 21 denote respectively a corrector circuit and a linearizer circuit, and the reference 22 an operator receiving on its input 23 a zero pressure variation instruction and on a second input 24 a signal representative for example of the pressure in space 3, which can be measured for example by a pressure sensor shown diagrammatically at 25; the loop 26 therefore transmits to the operator 22 this signal representative of the pressure in space 3.
