Definitions

  • the present invention relates to a door-locking device, in particular for a domestic appliance.
  • the subject of the invention is a door-locking device of the type defined in the preamble of claim 1.
  • a door locking device of this type is known, for example, from EP-A-0354 191 .
  • An object of the present invention is to provide a door-locking device of the type specified above in which the emergency release function is implemented reliably in a simple and inexpensive manner.
  • a door-locking device according to the present invention is generally indicated 1.
  • the device 1 comprises a support housing 2 made of electrically insulating material such as moulded plastics material.
  • the housing 2 is intended to be fixed to the structure of a domestic appliance (not shown) in the vicinity of a loading or access opening with which a door P, provided in known manner with a hook member A, is associated ( Figure 1 ).
  • the support housing is formed by two half-shells 3 and 4 fitted together (see, for example, Figure 2 ).
  • the housing 2 of the device 1 has an opening 5 for the introduction of the hook member A carried by the door P.
  • a restraining member or slider 6 mounted in the support housing 2 has an opening or window 7 ( Figure 1 ) through which the hook member A can extend.
  • the restraining member or slider 6 When the door P is open as in the condition shown in Figure 1 , the restraining member or slider 6 is held by an associated spring in a rest position in which its window 7 faces the opening 5 in the housing 2. In this condition, the hook member A of the door P can be introduced into the opening 5 and into the window 7 when the door P is closed and, conversely, can be released from the window 7 and from the opening 5 when the door P is opened.
  • the restraining member or slider 6 has two transversely projecting appendages, indicated 6a and 6b, respectively.
  • the appendage 6a is generally L-shaped with a proximal portion 6c arranged substantially transversely relative to the body of the slider 6 and a distal portion 6d which extends longitudinally, that is parallel to the main body of the slider 6.
  • the portion or arm 6d of the appendage 6a is longer than the portion or arm 6c and can be deformed flexibly towards the main body of the slider 6 as can be seen, for example, in Figure 5 .
  • the arrangement is such that, when the door P is closed, the hook member A engages in the opening or window 7 of the restraining member or slider 6 and brings about a translational movement thereof (towards the left as seen in Figure 1 ) so as to expose the opening 10 and the locking member 11, as shown in Figures 2 to 6 .
  • the locking member 11 is, however, still held in a retracted, release position and does not obstruct the translational movement of the slider 6. The door can therefore be reopened manually.
  • an actuator device (not shown) of the door-locking device 1 causes the locking member 11 to move from the retracted position ( Figure 6 ) to the projecting position ( Figure 4 ), in known manner.
  • the restraining member or slider 6 is prevented from returning to the rest position since the appendage 6b of the slider then interferes with the locking member 11. Re-opening of the door P is therefore prevented, that is, the door is closed and locked.
  • An emergency release of the door-locking device 1 to allow the door P to be re-opened can then be performed by means of an operating lever 12 formed integrally with a portion of the support housing 2, in particular with the half-shell 3 thereof.
  • the operating lever 12 comprises a proximal portion 12a which extends from the periphery of the half-shell 3, an intermediate portion 12b substantially parallel to the slider 6, and a terminal portion 12c substantially perpendicular to the slider 6 and to the portion 6d of the appendage 6a thereof.
  • the distal end of the portion 12c of the lever 12 advantageously bears on or is situated in the immediate vicinity of the portion 6d of the appendage 6a of the slider 6, as can be seen in Figures 3 and 4 in particular.
  • the lever 12 has a projection 12d which, as can be seen in Figure 6 , preferably projects relative to the support housing 2.
  • a pulling member such as, for example a Bowden cable
  • a pull on the cable member in a downward direction as seen in Figures 2 to 6 causes the terminal portion 12c of the lever 12 to engage the portion 6d of the appendage 6a of the slider 6 to an extent such that the distal end of the portion 6d interferes with the locking member 11 ( Figure 5 ) causing it to return to the retracted, release position in which it does not obstruct re-opening of the door P.

    un élément de verrouillage (11) qui peut être déplacé dans le logement de support (2) entre une position de libération et une position d'engagement dans lesquelles il permet et empêche respectivement le mouvement de l'élément de rétention (11) de la position de travail à la position de repos, et
    des moyens de libération d'urgence (6a ; 12) destinés à libérer l'élément de verrouillage (11) pour passer de la position d'engagement de l'élément ou coulisse de rétention (6) à sa position de libération,
    le dispositif de verrouillage d'une porte (1) étant caractérisé en ce que les moyens de libération d'urgence comprennent :
    un appendice flexible d'un seul tenant (6a) avec l'élément ou coulisse de rétention (6) qui peut adopter, quand la coulisse (6) est dans la position de travail et l'élément de verrouillage (11) dans la position d'engagement, un état inactif dans lequel il n'interfère pas avec l'élément de verrouillage (11) et un état actif dans lequel il interfère avec l'élément de verrouillage (11) de façon à le faire revenir dans la position de libération, et un levier d'actionnement (12) qui est formé d'un seul tenant avec au moins une partie (3) du logement de support (2) et qui provoque, lorsqu'il est actionné, le mouvement de l'appendice (6a) de l'élément ou coulisse de rétention (6) de l'état inactif vers l'état actif.
  2. Dispositif de verrouillage d'une porte selon la revendication 1, dans lequel l'appendice flexible d'un seul tenant (6a ; 6c, 6d) avec l'élément ou coulisse de rétention (6) est sensiblement en forme de L.
