Abstract
Description
- The present invention relates to a door lock, particularly for domestic electrical appliances such as, for example, washing machines or the like.
- More specifically, the particular object of the invention is a device for locking a door or the like, particularly for a domestic electrical appliance, of the type comprising:
- a support structure in which is defined an aperture into which, when the door is closed, it introduced a hook member connected to this door;
- a retainer slide, movable with respect to this structure between a working position in which it is able partially to obstruct the said aperture and to retain the hook member introduced into this aperture, and a rest position in which it is able to allow disengagement of the said hook member from the aperture in the door; and
- an electro-mechanical control device including a movable lock member displaceable, upon activation of the apparatus, from an inactive or release position to locking position in which it is able respectively to allow and to prevent the passage of the retainer slide from the working position to the rest position; an electric switch being associated with the said lock member, capable of changing condition or state when this lock member passes from the release position to the locking position and vice versa.
-
- Door lock devices of this type are well known. Such a device is described for example in Italian Patent Application TO2000A000658 in the name of the same applicant.
- Door lock devices of this type made until now have in general a very reliable and safe operation.
- One possible disadvantage of such devices, however, lies in the fact that if, during operation of the domestic electrical appliance, the closure door or hatch is subject to an opening force greater than a predetermined value (typically a value envisaged by the homologation rules for door lock devices) or if breakage of the hook member connected to the door takes place, this latter can open, whilst the domestic electrical appliance remains in operation, with the readily imaginable potential risks.
- One object of the present invention is therefore to provide a door lock device of increased safety which makes it possible to overcome the above-indicated disadvantage of prior art devices.
- This and other objects are achieved according to the invention with a door lock device of the type specified above, characterised in that it further includes a safety mechanism including:
- a feeler member, sensitive, when the door is closed, to the position of the hook member of the said door; and
- an intervention member associated with the said feeler member and operable, when the hook member is disengaged from the said feeler member whilst the said lock member is in the locked position, to interact
- with the said lock member by causing the return thereof of the release position; and
- with the retainer slide, locking it in its said working position.
-
- Further characteristics and advantages of the invention will become apparent from the following detailed description, given purely by way of non-limitative example, with reference to the attached drawings, in which:
- Figure 1 is a perspective view of the door lock device according to the present invention;
- Figure 2 is a partially exploded perspective view of the door lock device according to Figure 1;
- Figure 3 is a sectioned view essentially along the line III-III of Figure 1, showing this door lock device in a rest condition; and
- Figures 4 and 5 are views similar to that shown in Figure 3, and show the door lock device in an operative working condition and in an operative emergency condition.
-
- In the drawings, a door lock device according to the invention is generally indicated 1.
- In the exemplary embodiment illustrated this device comprises a
body 2 of moulded plastics material at one end of which is formed an aperture 3 (see in particular Figures from 3 to 5). - The
aperture 3 is able to allow introduction of a hook member, such as that indicated 4 in Figures 4 and 5. - In a manner known per se, the door lock device 1 can be fixed close to an opening of a domestic electric appliance, and the
hook member 4 is intended to be connected, for example in an articulated manner, to the movable door P associated with this aperture of the domestic electrical appliance. - In the embodiment illustrated the
hook member 4 comprises aleg 4a having an end articulated at 5 to the door P and another end which, after a narrowed section orneck 4b, forms an enlarged head indicated 6. - The
reference numeral 7 indicates a shaped slide, axially translatable with respect to thesupport body 2 along a direction approximately orthogonal to the direction of introduction of thehook member 4 into theapparatus 3. - The
slide 7 has amain aperture 8 which in the various operative conditions or positions of the slide are at least partially facing and aligned with theaperture 3 of thesupport structure 2. - A coil spring 10 (Figures 2 and 3) is interposed between the
slide 7 and thesupport structure 2 and tends to maintain theslide 7 in the rest position shown in Figure 3 in which theaperture 8 of this slide is aligned with theaperture 3 of thebody 2. When theslide 7 is in this position thehook member 4 of the door P can be introduced through theaperture 3 in such a way that its terminal head 6 projects beyond thisaperture 3 and engages in theaperture 8 formed in theslide 7 as shown in Figure 4. - Within the support body or
casing 2 is contained an electro-mechanical control device of type known per se. This device is, for example, of the type illustrated in detail and described in the earlier Italian Patent Application mentioned above. This electro-mechanical control device will therefore not be further described in all its detail, but rather solely in relation to the aspects relevant to the purpose of understanding of the present invention. - The electro-mechanical control device contained in the
support casing 2 includes a movable lock member, indicated 27 in Figures from 3 to 5. This member is mounted so as to be axially translatable, in a vertical direction as seen in Figures from 3 to 5, through anaperture 28 formed in the wall of the support casing 2 (Figures 4 and 5). - The
movable lock member 27 is displaceable, following activation of the apparatus with which the door lock device 1 is associated, from an inactive or release position shown in Figure 3, to a locked position shown in broken outline in Figure 4, in which it is able respectively to allow and to prevent passage of theretainer slide 7 from the working position to the rest position. - The
lock member 27 is associated, in a manner known per se and not illustrated, with an electric switch capable of changing condition or state when thislock member 27 passes from the release position to the locked position, and vice versa. One way of associating an electric switch with the lock member is described in detail in the above-mentioned Italian Patent Application. The electric switch associated with thelock member 27 in particular makes it possible to signal to the control unit of the domestic electric appliance, that the door P is closed and locked. - In relation to what has been described so far, the door lock device according to the invention corresponds substantially to the prior art devices, and functions essentially in the following way.
- When the door P of the domestic electrical appliance is open, the door lock device 1 assumes the rest configuration shown in Figure 3. In this condition the electro-mechanical control device contained in the
support casing 2 has no current flowing through it. Thelock member 27 is maintained in a retracted position shown in Figure 3, in which it does not project out of thesupport casing 2. Thespring 10 maintains theslide 7 in the rest position, in which itsaperture 8 faces theaperture 3 of thebody 2. - If the user closes the door P of the domestic electric appliance the
hook member 4 associated with this door passes through theaperture 3 of thebody 2 and engages in theaperture 8 of theslide 7 as shown in Figure 4. Theslide 7 is correspondingly translated towards the retention position as shown in Figure 4, against the action of thespring 10 which is compressed. - If the domestic electrical appliance is now activated an electric current flows in the electro-mechanical control device contained in the
support casing 2. In a manner known per se, after a certain predetermined time period, this current causes themovable locking member 27 to move into the extended position in which it is able to interfere with a portion orwing 7a of the slide 7 (see also Figure 2) preventing return of this latter towards the rest position shown in Figure 3. In this condition the door P is effectively closed and locked, that is to say it cannot be opened. This condition is detectable by the control unit of the domestic electrical appliance in that the switch associated with themovable lock member 27 has changed its condition or state. - The door P can subsequently be reopened only if the current flowing in the electro-mechanical control device housed in the
support member casing 2 is interrupted, for example, at the end of an operating cycle of the domestic electrical appliance, or following interruption of the electrical energy supply to this appliance. - When this happens, after a certain time, the
movable lock member 27 is returned to the retracted position in which it does not obstruct the return of theslide 7 towards the rest position of Figure 3. The door of the domestic electrical appliance can now again be opened. - The door lock device 1 further includes a security mechanism generally indicated 30. This mechanism comprises a lever generally indicated 31, having one
end 31a articulated to thesupport structure 2 about an axis defined by two aligned pegs or pins 32 (Figure 2 et seq). - The
opposite end 31b of thelever 31 faces theaperture 8 of theslide 7 on the opposite side of theaperture 3 of thecasing 2 from the said slide. - A coil spring indicated 33, has one end anchored to the
lever 31, at an intermediate point between itsends casing 2. Thespring 33 tends to bias thelever 31 towards thesupport casing 2 of the door lock device. - In an intermediate position between the anchorage of the
spring 33 and theend 31a theside lever 31 facing thesupport casing 2 has a projecting appendix indicated 34 in Figures from 3 to 5. This appendix is located substantially facing themovable lock member 27. - When the door lock device is in the rest position (Figure 3) the
slide 7 lies between themovable lock member 27, which is in the retracted condition, and the projectingappendix 34 of thelever 31. Thelever 31 rests on theslide 7 in correspondence with the said projectingappendix 34, under the force exerted by thespring 33. - When the door P of the domestic electric appliance is closed, the head 6 of the
hook member 4 engages through and beyond theaperture 8 of theslide 7 as is shown in Figure 4, going on to engage theend 31b of thelever 31 and causing this lever to turn about thepins 32 in a clockwise sense as seen in Figure 3. The projectingappendix 34 of thelever 31 is now lifted from theslide 7. - The
end 31b of thelever 31 acts, when the door is closed, as afeeler member 4 sensitive to the position of thehook member 4 of the door P. - The
lever 31 remains in the position illustrated in Figure 4 even when, after the operation of the domestic electrical appliance has started, thelock member 27 moves into the extended position in which it prevents return of theretainer slide 7 to the rest condition of Figure 3. In this condition theslide 7 partially obstructs the opening of theaperture 3 in thecasing 2, theaperture 8 of this slide being in part transversely offset with respect to theaperture 3. - If, whilst the domestic electric appliance is in operation a stress of exceptional magnitude is applied to the door P, this may cause breakage of the
hook member 4 or may force disengagement of this hook member from theslide 8. Thelever 31 of thesafety mechanism 30, under the action of thespring 33, immediately turns in an anticlockwise sense as seen in Figure 4, bringing it into the position shown in Figure 5. In this condition the projectingappendix 34 of thelever 31 forces themovable lock member 27 into the retracted position, but at the same time prevents return of theslide 7 towards the rest position. - Consequently, by the effect of the rotation of the
lever 31 of the safety mechanism, the switch associated with themovable lock member 27, which again changes condition or state, signals to the control unit of the machine that the door is no longer closed and locked, but rather is open. Moreover, theslide 7, which is held in the retention position in which it partially obstructs theaperture 3, prevents possible reintroduction of the head 6 of thehook member 4 of the door P. - To reinstate the door lock device to the rest condition of Figure 3, it will be necessary now to act on the
security lever 31 causing it to be pulled away from thesupport casing 2 so as to disengage theslide 7 from the projectingappendix 34 of the safety lever. - Naturally, the principle of the invention remaining the same, the embodiments and details of construction can be widely varied with respect to what has been described and illustrated purely by way of non-limitative example, without by this departing from the ambit of the invention as defined in the annexed claims.
