Definitions
- the present invention relates to a door lock, particularly for domestic electrical appliances such as, for example, washing machines or the like.
- 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:
- 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.
- a safety mechanism including:
- a door lock device according to the invention is generally indicated 1.
- 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.
- 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.
- the hook member 4 comprises a leg 4a having an end articulated at 5 to the door P and another end which, after a narrowed section or neck 4b, forms an enlarged head indicated 6.
- the reference numeral 7 indicates a shaped slide, axially translatable with respect to the support body 2 along a direction approximately orthogonal to the direction of introduction of the hook member 4 into the apparatus 3.
- the slide 7 has a main aperture 8 which in the various operative conditions or positions of the slide are at least partially facing and aligned with the aperture 3 of the support structure 2.
- a coil spring 10 ( Figures 2 and 3) is interposed between the slide 7 and the support structure 2 and tends to maintain the slide 7 in the rest position shown in Figure 3 in which the aperture 8 of this slide is aligned with the aperture 3 of the body 2.
- the hook member 4 of the door P can be introduced through the aperture 3 in such a way that its terminal head 6 projects beyond this aperture 3 and engages in the aperture 8 formed in the slide 7 as shown in Figure 4.
- 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 an aperture 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 the retainer 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 this lock member 27 passes from the release position to the locked position, and vice versa.
- an electric switch capable of changing condition or state when this lock 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 the lock 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.
- the door lock device according to the invention corresponds substantially to the prior art devices, and functions essentially in the following way.
- 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.
- the lock member 27 is maintained in a retracted position shown in Figure 3, in which it does not project out of the support casing 2.
- the spring 10 maintains the slide 7 in the rest position, in which its aperture 8 faces the aperture 3 of the body 2.
- 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.
- 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 the support structure 2 about an axis defined by two aligned pegs or pins 32 ( Figure 2 et seq).
- the opposite end 31b of the lever 31 faces the aperture 8 of the slide 7 on the opposite side of the aperture 3 of the casing 2 from the said slide.
- a coil spring indicated 33 has one end anchored to the lever 31, at an intermediate point between its ends 31a and 31b, and the other end anchored to the support structure or casing 2.
- the spring 33 tends to bias the lever 31 towards the support casing 2 of the door lock device.
- the end 31b of the lever 31 acts, when the door is closed, as a feeler member 4 sensitive to the position of the hook 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, the lock member 27 moves into the extended position in which it prevents return of the retainer slide 7 to the rest condition of Figure 3. In this condition the slide 7 partially obstructs the opening of the aperture 3 in the casing 2, the aperture 8 of this slide being in part transversely offset with respect to the aperture 3.
