Definitions

  • the present invention relates to a door lock for front-loading washing machines and driers of the kind defined in the first part of Claim 1.
  • GB-A-1 395 728 discloses a door lock device of this kind comprising a spring-loaded control lever articulated to the support body of the device and a latch plate coupled to the control lever and disposed substantially parallel thereto.
  • the latch plate carries a toothed latch member adapted to engage a retaining edge of an aperture provided in the door.
  • Said latch plate is mounted slidable through a boss carried by the control lever and a supplementary spring is needed to urge the latch plate towards the latching position and prevent the disengagement thereof from the door when the machine is in operation.
  • EP-A-0 296 510 which is comprised in the state of the art only pursuant to Articles 54(3) and (4) EPC and insofar some contracting states are concerned, discloses a door latch device comprising a spring-loaded control lever articulated to a latch plate which is mounted slidable in the support body of the device, substantially parallel to the control lever.
  • the object of the present invention is to provide a door release which is simple and cheap to produce and which enables the door to be opened by means of a push-button situated on the control panel of the machine and connected by means of a cable to the movable locking means associated with the support body of the lock.
  • a front-loading washing machine is generally indicated 1 and is provided with a front loading door 2 which can pivot about a vertical axis.
  • the machine includes a washing chamber 3 in which a drum 4 is mounted for rotation.
  • a lock 5, associated with the door 2 is carried by the structure of the washing machine and can hold the door closed when the washing machine is in operation.
  • the lock 5 includes a support body 6 fixed to the structure of the washing machine and having an aperture 7 for the passage of a hooked lever or catch member 8 articulated at 9 to a lateral edge of the door 2 with the interposition of a torsion spring 10 arranged to keep the catch member 8 in a position substantially perpendicular to the median plane of the door 2.
  • the support body 6 has a vertical guide 11 in which a rod-like slide 12 is slidable, the slide having a cut-out portion 13 in its lateral edge surface 12a whose width corresponds substantially to the width of the catch member 8.
  • the sliding of the slide 12 in the guide 11 is driven by a lever 14 perpendicular to the slide and having a first end 14a articulated at 15 to the body 5 and a second end 14b to which the end of an operating cable C is connected.
  • the lever 14 has a central horizontal slot 16 in which a pin 17, connected to one end 12b of the slide 12, is slidable in order to enable the slide itself to slide as a result of the rotation of the lever 14 about the fulcrum 15.
  • the lever 14 Near its second end 14b, the lever 14 has a side arm 18 with a hooked end 18a for cooperating with an abutment 19 which is adapted to project, in known manner, from the body 6 of the lock 5 when the machine is operating and to be flush with the support body 6 when the machine has stopped.
  • a helical tension spring 20 is interposed between the lever 14 and the body 6 for biassing the lever 14 to a substantially horizontal position.
  • lever of the lock may be operated by devices different from those described.

Claims (3)

  1. Verrouillage de porte pour machines à laver et séchoirs à chargement frontal, comprenant :
    - un corps support (6) adapté pour être fixé à la structure de la machine (1) ;
    - des moyens de verrouillage (12, 14) comprenant un coulisseau (12) agencé pour coopérer dans une première position avec un organe de retenue (8) fixé à la porte (2) pour maintenir la porte (2) fermée et pour se dégager dudit organe de retenue (8) dans une deuxième position, pour permettre l'ouverture de la porte (2) ; le coulisseau (12) étant articulé sur un élément levier (14) ayant une première extrémité (14a) articulée sur le corps support (6) et une deuxième extrémité (14b) reliée à un moyen de commande (C) qui peut être manoeuvré manuellement, et est capable de provoquer le pivotement de l'élément levier (14) de manière à dégager le coulisseau (12) dudit organe de retenue (8) ; et
    - des moyens de sécurité (19) comprenant une butée (19) agencée pour faire saillie latéralement sur le corps support (6) pour empêcher le pivotement dudit élément levier (14) lorsque la machine est en fonctionnement ;
    caractérisé en ce que le coulisseau (12) est disposé sensiblement perpendiculairement à l'élément levier (14) et présente un bord latéral (12a) qui est situé adjacent à une ouverture (7) prévue dans le corps (6) pour le passage de l'organe de retenue (8), le bord (12a) étant agencé pour attaquer l'organe de retenue (8) par encliquetage afin de maintenir la porte (2) fermée et ayant aussi une partie encochée (13) pour permettre à l'organe de retenue (8) de se dégager du coulisseau (12) lorsque ce dernier est entraîné en coulissement par l'élément levier (14).
  2. Verrouillage selon la revendication 1, caractérisé en ce que l'élément levier (14) possède un bras de retenue latéral (18) agencé, pour coopérer avec la butée (19) qui fait saillie sur le corps (6) pour empêcher l'élément levier (14) de pivoter lorsque la machine est en fonctionnement.
  3. Verrouillage selon une quelconque des revendications précédentes, caractérisé en ce qu'un ressort de traction (20) est interposé entre le corps support (6) et l'élément levier (14) pour tendre à rapprocher l'élément levier (14) de la position correspond à l'état fermé de la porte (2).
