Definitions

  • the invention relates to a top loading washing and spinning machine having a substantially flat door which pivots about a horizontal axis and which folds horizontally in the closed position, in which position it is locked by a mechanical device.
  • blocking device composed of a bolt mounted on the door and a keeper secured to the door frame, one of the two components of the locking device rotating to receive the other.
  • Such a machine is known as an example from French Patent No. 2,501,250.
  • French Patent No. 2,501,250 relates to a device in which the opening of the door remains impossible, regardless of the force with which the user tries to act on a lock, but this in a perfectly rigid mechanical structure .
  • an element therefore having considerable flexibility, the revolving striker and its hook are liable to become detached despite the security measures envisaged.
  • the subject of the invention is a washing machine and a machine where the opening of the door remains impossible. Mechanical deformations, due to vibrations, thermal shocks, and supported by plastic construction elements are recovered by the bolt. This is likely to compensate for the clearances which appear between the door and the door frame, during the use and the life of the machine.
  • the invention is characterized in that the bolt is a cylinder, the section of which is a closed curve with a radius varying in a discreet manner, bolt mounted for rotation on the door around an axis parallel to its generator and to the plane of the door and recalled by elastic means, which orient it, facing the keeper, according to increasing radii, bolt driven in rotation under the weight of the door, against the elastic means for escaping under said keeper, in the locked position, the keeper being constituted by an edge parallel to the bolt on which the bolt abuts when the door is closed, means for unlocking the door being likely to rotate the bolt against its elastic means for its erasure.
  • the surface of the bolt therefore has successive notches.
  • the means for unlocking the door are composed on the one hand, a movable sector transversely to the bolt, cooperating with a pinion integral with said bolt, and on the other hand, a handle freely pivoting relative to the sector and capable of pushing said sector for driving the bolt against its elastic means.
  • the unlocking system going against the elastic means, rotates the bolt so that the notches of the upper rib to the notch used are stressed in turn. The clearance between the bolt and the strike edge then increases until the bolt is cleared.
  • FIG. 1 shows the upper zone of a washing machine and spin dryer for top-loading laundry, the tub 14 of which is closed by a door 1 which pivots about the horizontal axis 2 and folds horizontally in the closed position , position in which it is blocked by a mechanical blocking device carried by two parallel flanges 5 molded with the door.
  • a bolt 3 is mounted for rotation about an axis 4, which is parallel to the plane of the door.
  • the two ends of the axis 4 of the bolt are housed in two holes in the flanges 5, mechanism support.
  • the edge of the tank 14 which forms, in this embodiment, the keeper 6, is in contact with the bolt.
  • the handle 7 is my rotating tee on an axis 8 parallel to axis 4 of the bolt.
  • the handle pin 8 is fixed to the door by its two ends, which are housed in two holes in the flanges 5 of the mechanism support.
  • Figure 2 shows the door locking mechanism
  • the bolt 3 a cylinder here partially shown, the section of which forms a closed curve of variable radius, is mounted for rotation about the axis 4 parallel to its generatrix and returned by elastic means which, in this exemplary embodiment, are consist of a helical spring guided by the axis of the bolt 4 and working in torsion.
  • elastic means which, in this exemplary embodiment, are consist of a helical spring guided by the axis of the bolt 4 and working in torsion.
  • One end of the spring 9 of the bolt bears on the door and the other end is housed in a form of fixing arranged in the bolt, shape not shown in FIG. 2.
  • a pinion 10 is molded, the axis of which merges with the axis 4 of rotation of the bolt.
  • the pinion 10 cooperates with a movable toothed sector 11 pivoting around the handle axis 8.
  • the mobile sector 11 is capable of being pushed by a molded form 13 of the handle, making a stop and driving the sector in rotation.
  • the handle 7 mounted on its axis 8 has elastic return means.
  • these elastic means are represented by a helical spring 12 working in tension.
  • the handle spring 12 is fixed on the one hand, to an eyelet molded with the door handle 7 and on the other hand, to an eyelet molded with the door itself.
  • the illustrated device operates in the following manner.
  • Figures 3a, 3b and 3c are diagrams showing the successive stages of the operation of closing the door.
  • Figures 4a, 4b and 4c are diagrams showing the successive stages of operation of the locking device when the door is opened.
  • the opening of the door is caused by the handle 7 which is pivoted about the axis 8 in the direction of the arrow C, against the force exerted by the handle spring 12, shown in the Figure 2.
  • the stop 13 pushes the movable sector 11 rotatably mounted about the axis 8.
  • the movable sector 11 cooperates with the pinion 10 of the bolt by means of teeth, and drives said pinion.
  • the pinion 10 integral with the bolt pivots in the direction of arrow D and goes against the force exerted by the spring 9 of the bolt.
  • the bolt 3, the radius of curvature of which varies discreetly, is oriented in front of the striker according to the decreasing radii, which allows it to be released from below the striker (FIG. 4b).
  • the full pivoting of the handle completely releases the bolt from underneath the keeper ( Figure 4c). It is then possible to raise the door 1 of the tank 14.
