Field of the invention
The present invention relates to a door-locking device for locking in a closed position the door of a domestic appliance, such as a washing machine or the like.
In particular, the present invention relates to a door-locking device which can be fixed on a front panel of a domestic appliance without screws.
Related art
WO-A-2010/101533 discloses a fastening device which can be used for fixing without screws a door-locking device to the front panel of a domestic appliance. The fastening device has a body with an engagement portion projecting from a bottom wall and including first and second opposite teeth adapted to engage opposite edges of an aperture of the front panel. The fastening device includes a protection plate including a pair of integral pins which are adapted to engage respective holes formed in the front panel. The protection plate is movable with respect to the body of the fastening device between an unlocking position and a locking position. In the locking position the pins snap engage the body of the fastening device, so as to fix the protection plate to the body. In the fastened position the pins have respective ends which project from the bottom wall of the body.
One of the drawbacks of the solution according to WO- A-2010/101533 is that for mounting the door-locking device on the domestic appliance the operator must first engage the door-locking device with the aperture of the front panel of the domestic appliance and then push the protection plate in the locking position. This solution cannot be used in all models of domestic appliances . A further drawback is that the protection plate could snap to the locking position during transport and delivery; in such case it would not be possible to mount the door-locking device on the domestic appliance.
WO-A-2010/0092529 discloses a door-locking device comprising a rigid body having a protruding structure in which there is provided an opening intended to receive a hook connected to the door of the domestic appliance. The body has two seats provided on opposite sides of the protruding structure and intended to engage corresponding edges of an opening provided in a front panel of the domestic appliance. A member of resilient material is overmoulded inside a first seat. The body has a pair of rigid projection capable of engaging corresponding through holes of the front panel.
This solution has the disadvantage of reguiring a member of resilient material overmoulded in the seat of the engagement portion, in order to allow a resilient movement needed for the engagement of the rigid projections with the corresponding holes of the front panel.

Description of embodiments of the invention
With reference to figures 1 and 2, a door-locking device according to the present invention is indicated by the reference number 10. The door-locking device 10 is intended to be mounted on a front panel P of a domestic appliance. The front panel P has a guadrangular opening 12 and a pair of circular holes 14 set on opposite sides of guadrangular opening 12.
The door-locking device 10 comprises a housing 16 and a locking slider 18 which is movable with respect to the housing 18 along a longitudinal direction indicated by the double arrow A. The slider 18 has an aperture 20 which is intended to receive a hook connected to the door (not shown) of the domestic appliance. The housing 16 contains an electrically actuated locking mechanism adapted to lock the slider 18 in a locking position, in which the slider 18 locks the door in the closed position.
The door-locking device 10 comprises a fastening portion 22 adapted to fix the door-locking device 10 to the front panel P without screws. The fastening portion 22 comprises a body 24 of injection-moulded plastic material. The body 24 is fixed to or integral with the housing 16 of the door-locking device 10. The body 24 has a channel 26 in which is movably guided the slider 18. The body 24 has an aperture 28 (figure 2) aligned with the aperture 20 of the slider 18 and adapted to receive the hook of the door. The body 24 has an integral engagement portion including first and second teeth 30, 32 projecting from a bottom wall 33 of the body 24 on opposite sides of the aperture 28. The teeth 30, 32 are configured for engaging opposite edges of the aperture 12 of the front panel P, as will be disclosed in the following.
The fastening portion 22 comprises a protection plate 34 fixed to the side of the body 24 opposite to the bottom wall 33, so as to close the upper part of the body 24. The protection plate 34 is a separate component with respect to the body 24. The protection plate 34 comprises a base wall 36 having an aperture 38 aligned with the apertures 20, 28 of the slider 18 and body 24. The base wall 36 has a pair of integral tabs 40 projecting therefrom and configured for snap-engaging respective teeth 41 integral with the body 24. The protection plate 34 also includes a pair of integral projecting pins 42 which project from lateral portions of the base wall 36 orthogonally thereto. The pins 42 are inserted with play into respective elongated holes 44 of the body 24. The pins 42 are free to move axially into the holes 44 when the protection plate 34 is fixed to the body 24 by means of the tabs 40. The axial movement of the pins 42 into the respective elongated holes 44 is allowed by an elastic deformation of the lateral portions of the base wall 36. When the protection plate 34 is fixed to the body 24, the front ends of the pins 42 project from the bottom wall 33 of the body 24. The front ends of the pins 42 are intended to engage into the holes 14 of the front panel P, as will be disclosed in the following.
The seguence of the steps for fastening the door- locking device 10 to the front panel P are described in the following with reference to figures 3 to 10. In a first step, as shown in figures 3 and 6, the door-locking device 10 is moved towards the panel P in the direction indicated by the arrow B so as to engage the first tooth 30 with a first edge the guadrangular opening 12 of the front panel P. In this condition, the first tooth 30 is positioned on the front side of the panel P, whereas the second tooth 32 is on the rear side of the panel P.
In a second step, as shown in figures 4 and 7, the door-locking device 10 is rotated towards the panel P in the direction indicated by the arrow C, so that the second tooth 32 passes through the opening 12 and is positioned on the front side of the panel P. In this condition the ends of the pins 42 are not engaged with the holes 14. The front ends of the pins 42 abut on the inner surface of the panel P. Therefore, the pins 42 are in retracted position with respect to the body 24. In this condition, the lateral portions of the base wall 36 of the protection plate 34 are elastically deformed as shown in figure 9.
In the final step, as shown in figures 5 and 8, the door-locking device 10 is moved in the direction indicated by the arrow D. This movement brings the second tooth 32 in engagement with the second edge of the opening 12 and, at the same time, brings the front ends of the pins 42 in correspondence with the holes 14 of the front panel P. When the front ends of the pins 42 meet the holes 14, the pins 42 snap into engagement with the holes 14 under the elastic force which returns the base wall 36 in the undeformed position .
As shown in figure 10, in the final position the pins 42 are in an extracted position with respect to the body 24 of the fastening portion 22. The front ends of the pins 42 which project beyond the bottom wall 33 of the body 24 engage the holes 14 of the front panel P. In this condition both the first and the second tooth 30, 32 are engaged with respective edges of the opening 12. In this condition the door-locking device 10 is fixed to the front panel P.
In the embodiment shown in figures 1 to 10 the protection plate 34 has two pins 42. However, the fastening of the door-locking device 10 would be egually effective even with only one pin 42. Figures 11-13 show a second embodiment of the present invention wherein the protection plate 34 is provided with only one pin 42. In this second embodiment, the body 24 of the fastening portion 22 has a rigid projection 46 projecting from the bottom wall 33, opposite to the front end of the pin 42 with respect to the opening 28.
The mounting seguence of the door-locking device of figure 11 is identical to what previously described. Figure 12 shows a condition corresponding to figure 9. The pin 42 is in the retracted position and the corresponding lateral portion of the base wall 36 of the protection plate 34 is deformed. The rigid projection 46 abuts against the inner surface of the front panel P and the corresponding lateral portion of the body 24 is elastically deformed. When the door-locking device 10 is moved in the final fastening position, the front end of pin 42 and the rigid projection 46 engage the respective holes 14, as shown in figure 13. The pin 42 is moved to the extracted position by the elastic return force of base wall 36 of the protection plate 34 whereas the rigid projection 46 is moved into engagement with the hole 14 by the elastic return force of the body 24. Figures 14 to 16 show a third embodiment of the present invention. The protection plate 34 has a single pin 42 as in the second embodiment. In this case, there is no rigid projection on the bottom wall 33 of the body 24. As shown in figure 15, in this case there is no deformation of the lateral portion of the body 24 during the fastening operation of the door-locking device. Figure 16 shows the final fixing position with only one pin 42 engaging the respective hole 14.
