Definitions

  • the subject of the invention is a torque variator for a sliding door, in particular for an insulated watertight door fitted to a cold store.
  • sliding doors are usually equipped at their upper part with guide rollers thanks to which they are suspended from a sliding rail, and they move between a closed position to guarantee perfect sealing, and an open position. So that when closing, the seal is ensured, it is known to equip the sliding rail with notches oriented downwards and judiciously arranged, so that when the rollers descend into these notches, the door undergoes a identical movement of descent which applies the door seals to the floor as well as to the frame of the frame.
  • a currently widespread solution consists in connecting the door to a movement transmission member constituted for example by an endless chain or belt returning on two pinions, each placed at a end of the door travel zone.
  • a clutch linked to a motorization ensures the transmission of movement between a geared motor group and a drive pinion.
  • the torque exerted by the clutch is sufficient, not only to detach the door from the seals against which it is applied and to overcome the friction resulting therefrom, but also to disengage the rollers from their notches in order to reassemble the door on the horizontal running part of the rail.
  • these insulated doors are often heavy, the effort required is significant, but only during the very first phase of opening the door.
  • this second booster or start-up group has a power and develops a torque greater than that of the first, and advantageously its output shaft carries a cam which cooperates with a roller carried by the door, a cam whose active part exerts briefly, and in less than a turn, a significant force on the roller to release the door from the notches, as described in FR-A 2 451 445 in the name of the Applicant.
  • the invention provides a new and effective solution to these problems, in that it uses the geared motor group necessary for moving the door, but by associating it with a torque variator device which modulates the pressure exerted by the clutch when starting the opening movement, in relation to the continuous movement of the door.
  • a torque variator device which modulates the pressure exerted by the clutch when starting the opening movement, in relation to the continuous movement of the door.
  • a main object of the present invention therefore consists of a torque variator for a door. sliding moved on a rail by a transmission member such as a belt, driven by a single motor and comprising a main variator recalled by a spring for adjusting the clutch torque, variator which comprises an additional device controlled by the member transmission itself, and which changes the clutch torque of the main variator - during the first phase of door opening.
  • a transmission member such as a belt
  • variator which comprises an additional device controlled by the member transmission itself, and which changes the clutch torque of the main variator - during the first phase of door opening.
  • the additional device consists of a needle modifying the pressure exerted on a clutch ring of the drive pulley of the transmission member, under the action of a leaf spring, the displacement is slaved to the displacement of the transmission member.
  • the movement of the leaf spring to the transmission member is enslaved by a screw retaining said leaf which moves inside a threaded well constituting the fixed axis of rotation of a wheel driven by said transmission member.
  • the needle is mounted in a threaded cradle secured to the leaf spring, which carries a transverse spacer serving to support a T-shaped screw head.
  • the door 9 In the position shown, the door 9 is closed and the carrier rollers are immobilized in two notches 4 provided on the rail.
  • the door is driven from this position to an open position - shown in dotted lines - by an endless belt 5 to the lower strand from which it is attached by a connecting member 6.
  • the belt returns to a tension pulley 7 and to a drive pulley 8 forming part of the motorization group designated as a whole by the reference 1.
  • FIG. 2 The latter is shown in more detail in FIG. 2. It comprises a geared motor 10 for driving the driving pulley 8 on which the toothed belt meshes 5. This drive is provided by means of clutch crowns 11 fitted with linings 12 which can enclose the inside flanks of the pulley like a jaw.
  • a stop 14, bearing on a clutch ring 11, is integral with a rod 13 axially passing through the pulley and the motor, said rod being biased downwards by a return spring 15 housed in a cup 16, a spring of which the restoring force is adjusted by the adjusting screw 17.
  • the only force of the spring 15 exerts a fairly low clutch pressure but sufficient to drive the pulley 8, the belt 5 and therefore the door 9 in the horizontal displacement zone opening or closing.
  • This assembly constitutes the main variator which allows the adjustment of the clutch torque.
  • the main variator is completed by an additional device which modifies the clutch torque of the main variator during the first phase of opening the door and which consists of a needle 18 mounted in a threaded cradle 19, a needle whose point lower abuts against the stop 14.
  • the cradle 19 is integral with a leaf spring 20 developing on one side of the toothed belt. We see in Figure 3 the profile of this blade 20, which is attached to a plate 21, which receives the cradle 19.
  • the plate 21 is fixed, on the opposite side to the blade, to a shaft 22.
  • the end of the spring blade 20, consequently liable to deviate more or less from the toothed belt 5, carries a transverse spacer 23, serving itself a support for the head 28 in the T shape of a screw 24 which can slide in a guide well 25 fixedly mounted on the other side of the belt 5.
  • This well 25 constitutes the axis of rotation d 'a toothed wheel 26 mounted on the axis via the bearings 27. Said wheel is driven by the toothed belt between the strands of which it is placed. Its internal axis is tapped so that its rotation acts on the thread of the screw 24 which then moves transversely in the guide well, driving the head 28 to move the leaf spring 20 from the position shown in Figure 2 for reach the position shown in figure 4.
  • the screw therefore slides in the well 25, its rotation being blocked by a hexagonal nut 29. In this way, the movement of the leaf spring is therefore controlled by the movement of the belt.
  • FIG. 2 shows the device when the sliding door is closed, that is to say when its carrier rollers are immobilized in the notches.
  • the screw 24 occupies, inside the guide well 25, the position shown for which the T-shaped head 28 maintains the leaf spring 20 by exerting on it a pressure which is transmitted by the plate 21 to the needle 18.
  • This pressure significantly completes - due to the lever arm that constitutes the blade 20 - the normal pressure exerted by the spring 15 on the clutch crowns 11.
  • the "tight" clutch of the driving pulley will thus favor the exit of the sliding door, out of its notches when starting the gear motor.
  • the belt 5 moves in the opposite direction and inversely actuates the toothed wheel 26 which has the effect of moving the screw 24 towards the interior of the well.
  • the head 28 then drives the leaf spring 20 in the direction of the belt causing a progressive increase in the force exerted by the needle 18 on the clutch stop.
  • the clutch pressure is maximum; the device is ready for reopening.
  • Adjustments are provided at the needle 18 and the screw 24 to adapt their movement to the stroke and the weight of the door.
  • the invention is not limited to the example of description shown but also encompasses the variants, in particular as regards the method of driving the door which can also use a chain, etc.
