Definitions

  • the invention relates to a top-loading washing machine having a substantially flat door which pivots about a horizontal axis and which folds horizontally in the closed position, position in which it is locked by a mechanical locking device composed a bolt mounted on the door and a keeper secured to the door frame, one of the two components of the rotary locking device to receive the other.
  • a mechanical locking device composed a bolt mounted on the door and a keeper secured to the door frame, one of the two components of the rotary locking device to receive the other.
  • 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 In the case of a construction made of molded plastic elements, an element therefore having considerable flexibility, the revolving striker and its hook are liable to become detached despite the security measures envisaged.
  • the invention relates to a washing machine in which 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 and the radius of which varies discreetly in the zone of cooperation with the keeper, the bolt being mounted for rotation on the door around of 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, the bolt being driven in rotation under the weight of the door, in 'against elastic means for escaping under said keeper, in the locking position of the door, the keeper consisting of 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 can therefore have successive notches.
  • FIG. 1 shows the upper zone of a top-loading washing machine, 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 mounted for rotation on an axis 8 parallel to the axis 4 of the bolt the handle axis 8 is fixed to the door by its two ends, which are housed in two holes arranged in the flanges 5 mechanism support.
  • Figure 2 shows the door locking mechanism
  • the bolt 3 a cylinder here partially represented felt, the section of which forms a closed curve of variable radius, is mounted to rotate about the axis 4 parallel to its generatrix and recalled by elastic means which, in this exemplary embodiment, consist of a guided helical spring by the axis of the bolt 4 and working in torsion.
  • elastic means which, in this exemplary embodiment, consist of a guided helical spring 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.
  • the bolt is oriented facing the keeper according to increasing radii which allows it, after exhaust, to come into abutment under the keeper and thus to block the door (figure 3c).
  • 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.
