Definitions

the present invention relates to a system for screwless fixing of a body having a projecting formation, such as the body of a door-locking device for a washing machine, to a panel with an opening, for example a front panel of a washing machine, of the kind defined in the preamble of claim 1.
EP-A- 1 418 266 discloses such a system wherein pins resiliently carried by the body engage corresponding holes in the panel.
the object of the present invention is to provide a screwless fixing system of the improved type, implementation of which is particularly simple and operation of which is reliable and secure.
the locking member is displaceable from the pre-engagement position into the engaged position essentially by means of a translation.
the locking member is displaceable from the pre-engagement position into the engaged position by means of a rotation about an axis essentially parallel to the panel.
FIG. 1 denotes overall a door-locking device for a washing machine, in particular a clothes washing machine, for example of the type described in the European Patent Application EP 1 544 387 A2 or in the application EP 1 467 048 A1 , both in the name of the same Applicant.
the projecting formation 3 of the door-locking device has an essentially rectangular general shape, with a main axis or direction indicated by A-A in Figure 1 .
the door-locking device 1 is intended to be fixed to a front panel of the washing machine, for example the panel indicated by 5 in Figures 4 to 9 .
This panel has an opening 6, which also has an essentially rectangular shape.
the projecting formation 3 of the door-locking device has a head portion 3a which, in the direction of the axis A-A, has an extension greater than the corresponding larger dimension of the opening 6 of the panel 5.
the projecting formation 3 also has a neck portion, indicated by 3b (see, for example, Figures 3 , 4a and 4b ) which in the direction of the axis A-A has an extension which is smaller than or at the most essentially the same as the larger dimension of the opening 6 of the panel 5.
a locking member is associated with the plate-shaped body 2 of the door-locking device.
the locking member 7 comprises an essentially plate-shaped body 8 which, on its periphery, has a plurality of resilient eyelet lugs 9 which are able to snap-engage with corresponding projections 10 of the body 2 of the door-locking device 1 (see in particular Figures 1 to 3 ).
the body 8 of the locking member 7 also has a plurality of resilient retaining formations 11, the distal end of which has a laterally projecting tooth-like formation 11 a with an inclined end surface 11b.
the plate-shaped body 2 of the door-locking device 1 has a corresponding plurality of openings 12 ( Figures 1 , 3 , 4b, 5b , 10 ). These openings have an outer part , namely the retaining formation or formations 12a ( Figures 4b, 5b , 6b, 7 , 8b ) with an inclined inner surface 12b.
the arrangement is such that the locking member 7 is able to assume, relative to the body 2 of the door-locking device 1, a pre-engagement position, shown in Figures 1 , 2 and 4a to 7 .
the resilient formations of the locking member 7 are engaged with the corresponding projections 10 of the door-locking device 1, as is shown in Figures 1 and 2
the retaining formations 11 of the locking member have respective inclined end surfaces 11 b which rest against the corresponding inclined surfaces 12b of the openings 12 of the door-locking device, as can be seen in particular in Figures 1 , 4b , 5b , 6b , 7 and 8b .
the retaining formations 11 are moreover disengaged from - or not engaged with - the reataining formation or formations 12a of the door-locking device.
the door-locking device 1 is conveniently engaged with the opening 6 of the panel 5 of the machine while the associated locking member is mounted thereon and is situated in the pre-engagement position described above.
Mounting of the door-locking device is performed in particular in the manner described below.
the projecting formation 3 of the door-locking device is passed, in an inclined position, through the opening 6 of the panel 5.
the door-locking device 1 is then rotated in the direction of the panel 5, as shown in Figures 5a and 5b , until the projecting formation 3 is positioned beyond this panel.
the door-locking device 1, with the associated locking member 7 in the pre-engagement position is then displaced, towards the right when viewing Figures 5a and 5b , until the engaged position shown in Figures 6a, 6b and 7 is reached. In this condition, both the ends of the head portion 3a of the projecting formation 3 extend outside the opening 6 of the panel 5 ( Figure 6a ).
a step indicated by 13 is formed (see in particular Figures 1 and, for example, 6a) able to be arranged so as to bear against a corresponding side of the opening 6 of the panel 5 ( Figure 6a ).
the locking member 7 may be manually displaced from the pre-engagement position, into an engaged and locked position, by means of displacement thereof in the direction of the said door-locking device and therefore in the direction of the panel 5.
the tooth-like ends 11 a of the retaining formations 11 of the locking member 7 pass over the associated retaining formation or formations 12a of the body 2 of the door-locking device, snap-engaging with a stable retaining engagement beyond said walls and coming into contact with the surface of the panel 5 situated on the opposite side to the projecting formation 3 ( Figures 8a, 8b and 9 ).
the door-locking device and the associated locking member are firmly fastened to the panel 5 and displacement thereof relative to this panel is prevented.
the body 2 of the door-locking device has a plurality of openings 14 inside which corresponding, essentially cylindrical, relief formations 15 of the body 8 of the locking member 7 are able to extend in a guided manner.
the formations 15, as can be seen in Figure 10 may if necessary project beyond the body 2 of the door-locking device when the latter is fastened to the panel 5 following the arrangement of the locking member 7 in the engaged position described above.
the ends of the formations 15 may then press against the inner surface of the panel 5 or if necessary engage inside corresponding openings provided in this panel.
Figures 11 to 19 show a variation of embodiment where the locking member 7 is able to pass from the pre-engagement position, shown in Figures 11 , 12 , 14b-16b as a result of a relative rotation thereof with respect to the body 2 of the door-locking device, about an axis essentially parallel to the panel 5.
the body 2 of the door-locking device has two openings 16 which are aligned together in a direction B essentially perpendicular to the axis A-A of the projecting formation 3 and the corresponding opening 4.
Respective cylindrical reliefs 17, aligned and facing each other in the direction B-B, extend inside the openings 16.
two resilient engaging lugs 18 extend from the body 8 of the locking member 7, essentially in the form of elongated eyelets able to extend inside the openings 16, engaging around the reliefs 17 (see, for example, Figures 13 and 15a ).
the aligned reliefs or pins 17 define therefore an axis of relative rotation of the locking member 7 with respect to the body 2 of the door-locking device 1.
the body 2 of the door-locking device has a plurality of openings 19 (see, for example, Figures 11 , 13 , 14 , 15b , 16b and 18 ) through which corresponding opposition reliefs 20 extend and project from the body 8 of the locking member 7.
the locking member 7 is able to assume, relative to the body 2 of the door-locking device 1, a pre-engagement position where the retaining formations 11 of the former rest against the inclined surfaces 12b of the corresponding retaining formations 12a of the latter (see, for example, Figures 15b ).
the door-locking device may then be engaged with the opening 6 of the panel 5 in a manner similar to that described in relation to the first embodiment described previously.
the head portion 3a of the projecting formation 3 of the door-locking device is passed through the opening 6 of the panel 5 in an inclined position and is then rotated ( Figures 16a, 16b ) until said projecting formation 3 is positioned completely beyond the panel 5.
the opposition reliefs 20 of the locking member 7 are arranged against the surface or the side of the panel 5 opposite the projecting formation 3 ( Figures 16b ).
the assembly formed by the door-locking device and the associated locking member 7 is then displaced, parallel to the panel 5, until the projecting formation 3 reaches the engaged position where its step 13 is arranged inside the opening 6 of the panel 5, along one side of this opening.
the arrangement is such that, as a result of said displacement and reaching of the engaged position described above, following contact of the reliefs 20 against the panel 5, the locking member 7 automatically performs a rotation about the axis of the pins 17, passing into the condition shown in Figures 17a, 17b and 18 , where the end teeth 11 a of the retaining formations 11 have snap-engaged beyond the retaining formations 12a of the door-locking device and press against the panel 5, ensuring in fact stable fixing of the door-locking device to the panel. In this condition, owing to the engagement of the members 11 and 20 with the panel 5, any play between the device 1 and the panel is eliminated.
