Definitions

  • the present invention relates to a motorized tilting garage door according to the preamble of claim 1.
  • this consists of an opening, made integral with a sleeping frame by means, on the one hand of rollers capable of moving in vertical slides of the frame and on the other hand of a compass arm interposed between said frame and opening it. Its tilting command to an open or closed position is effected by means of a motor mounted on the leaf and of which an output shaft is rotationally integral with the end of the compass.
  • the power of these motors, whether electric or hydraulic, is adjustable, knowing that for an electric motor, there is also, in known manner, a potentiometer for adjusting the power on the rise and often a another potentiometer for adjusting the power when the sash is lowered.
  • the power is adjusted by means of two bypass valves.
  • a motorized tilting garage door corresponding substantially to the above description.
  • the motor disposed on the opening, rotates a threaded rod on which is mounted a nut itself secured to a lever arm arranged along a transmission shaft.
  • This acts, at the level of its ends, on the compass arms connecting the sash to the frame.
  • This garage door is also provided with elastic return means in the form of helical or spiral springs playing the same role as the counterweights which, moreover, equip said door.
  • these elastic return means have the function of compensating for the weight of the door and the springs are under maximum tension when the door is closed, while it decreases progressively as the window opens.
  • the opening is pivotally mounted on the sleeping frame around an axis of rotation which is not located, substantially, at the horizontal median plane of this opening, but in an offset manner. This obviously results in an imbalance mounting.
  • the present invention aims to remedy these drawbacks and relates, for this purpose, a motorized tilting garage door consisting of an opening made integral with a sleeping frame by means, on the one hand, rollers or guide means similar, able to move in vertical slides of the sleeping frame and on the other hand, of at least one compass arm interposed between said sleeping frame and the opening, its tilting control to an open or closed position effected by means of a motor mounted on the sash and of which an output shaft is rotationally integral with one end of a compass arm, characterized in that the motor comprises means for regulating its useful output power, starting from a constant nominal power of said motor authorizing both an increase and a decrease of this useful output power during the same opening or closing operation of the opening, in a way e to compensate, proportionally, the variations in force necessary for controlling this opening, as a function of its angular position relative to the frame.
  • the present invention also relates to the characteristics which will emerge during the description which follows, and which should be considered in isolation or according to all their possible technical combinations.
  • the invention suggests several solutions, one of which consists in absorbing and storing, mechanically, the additional power transmitted, at certain times, by the motor to the opening, these means mechanical being possibly able to restore this power during the reverse order.
  • the other solution consists in intervening on the engine power regulation means, on the potentiometers of an electric motor or on the bypass valves of a hydraulic motor, so that this power is adapted to the necessary power. to the control of the opening according to the position of the latter.
  • the tilting door 1 designated as a whole, consists of an opening 2, secured to a sleeping frame 3 by means of, on the one hand, rollers 4 or other guide means capable of moving in vertical slides (not shown) of the sleeping frame 3 and, on the other hand, of at least one compass arm 5 interposed between said frame 3 and the opening 2.
  • the tilting command to an open O or closed F position is effected by means of a motor 6 mounted on the opening 2 and of which an output shaft 7 is rotationally integral with one end 5a of the compass arm 5.
  • the motor 6 is arranged on a plate 8 and constitutes, with associated regulation means, an operator 9 generally designated.
  • the motor 6 includes means 10 for regulating its useful output power from a constant nominal power of this motor.
  • these regulation means 10 is to allow both an increase and a decrease in this useful output power during the same opening or closing maneuver, so as to compensate, proportionally, the variations in force necessary for controlling this opening 2 as a function of its angular position relative to the sleeping frame.
  • the present invention relates, more particularly, to garage doors, the opening of which is pivotally mounted on the sleeping frame around an axis of rotation substantially offset from its horizontal median plane, this mainly in order to limit the part of the opening projected externally to this sleeping frame, as visible in Figure 3.
  • said regulating means 10 are constituted by an elastic compensating member 10. This is interposed between, on the one hand, a fixed part 11 of a plate 8 on the opening 2 , for example, at casing of the control motor 6 and on the other hand of an end 12a of a link 12, the opposite end 12b of which is mounted in rotation with the output shaft 7 of the motor 6, therefore of the end 5a of the arm of compass 5 with which said link 12 forms a constant angle ⁇ of predetermined value.
  • the elastic member 10 constitutes a resistant torque which absorbs and stores an inertial force proportional to the weight and the speed of the opening 2, this more particularly in a final phase of closing F or opening O, to tend to brake it, and restore said force at the start of a reverse command, this in order to overcome a static force of said opening 2 proportional to its weight.
  • the elastic member 10 is a spring acting in traction.
  • One of the ends 10a of the tension spring 10 is, precisely, made integral with said fixed part 11 on the opening leaf 2, for example of the motor casing 6 or of its support plate 8.
  • this connection at this level can be done via an adjusting member 13 of the nominal tension of said spring 10.
  • the link 12A can comprise a plurality of anchoring points 14, from an opposite end 10b of the tension spring 10, so as to modify its component relative to the shaft.
  • output 7 of the motor 6 to which it is integral this as a function of variable parameters from one part to another.
  • an opening 2 on its trajectory between the open position O and closed position F usually passes through an unstable equilibrium position, this being caused to vary from one door to another.
  • the link 12A is a circular sector, one end 12Aa of which includes anchoring points 14, in fact holes in which the end 10b of the spring 10 is hooked and of which its end 12Ab is integral in rotation of the output shaft 7, or of the end 5a of the compass arm 5, as already mentioned above.
  • a motor 6 usually comprises an output shaft 7 opening out on each of its lateral sides so that the compensation means 10 can be placed on the opposite side with respect to the compass arm 5.
  • these means of compensation can cooperate with any part set in motion under the action of motor 6, as soon as they allow the desired result to be obtained.
  • one can use a spring but also rubber elements of the silentbloc type or the like.
  • the elastic member 10 exerts any torque on the output shaft 7 of the motor 6 only if its action is not reflected by a force passing through the axis of this shaft 7 and therefore located in the extension of the link 12 or 12A.
  • the means for regulating the output power of the motor 6 as a function of the angular position of the leaf 2 are electric and are constituted by control means capable of acting on two potentiometers 19, 20 equipping said motor 6 and determining the power of the latter, respectively when the door is opened and closed.
  • said control means are in the form of a cam 15 disposed on the output shaft 7 of the motor 6 which is rotationally integral with one end 5a of the compass arm 5.
  • Said cam has a profile 16 eccentric on which two probes 17 and 18 are supported mounted in opposition and connected to sliders corresponding to the two potentiometers 19 and 20 respectively for opening and closing with a view, precisely, to modulating the power of the motor 6 as a function of the angular position of the leaf 2 relative to its frame 3.
  • the positioning of the probes 17 and 18 of the potentiometers 19 and 20 on the eccentric cam 15 and the very profile 16 of the latter are determined as a function of the power stroke of the motor 6 required in opening 0 or in closing F.
  • the means for regulating the output power of the motor 6 as a function of the angular power of the opening 2 are constituted by an electronic card (not shown) comprising a preprogramming of a given power curve of the motor 6, depending on whether it acts in opening or closing the opening 2 and a reset system at each opening or closing limit switch.
  • the electronic card is connected to means for detecting the angular position of the opening acting on the power of the motor 6 as a function of the information received.
  • These detection means are constituted by a coded wheel, placed on the output shaft 7 of the motor 6 for example.
  • the means for regulating the output power of the motor 11 as a function of the angular position of the leaf 2 are hydraulic and are constituted by two bypass valves, the one opening 21, the other closing 22 controlled by suitable means, such as two cams 23 and 24 arranged on the output shaft 7 of the motor 6 and acting on the by-pass by means of transmission 25, 27; 26, 28 adequate.
