Description
- The present invention relates to a retaining device, in particular for a door or flap of a domestic electrical appliance, such as a washing machine.
- The invention relates more particularly to a retaining device of the type comprising:
- a support structure adapted to be secured to the door and in which an oscillating hook member, projecting at least partially outside this structure, is mounted and,
- a door locking device adapted to be secured in the domestic electrical appliance facing an opening provided in the appliance, and comprising a slider which is movable in translation and is adapted to occupy a rest position in which it enables the insertion and detachable engagement of the hook member with the retaining formation associated with said opening, so that the door is retained but not locked in the closed position, and a locked position in which the slider prevents the hook member from being disengaged from the retaining formation and locks the door in the closed position.
- Retaining devices of this type are known in which it is possible to open the door by actuating an appropriate handle or grip when the door locking device is in the rest position.
- An object of the present invention is to provide a retaining device of the above-described type which is adapted to enable, when the door locking device is in the rest position, the door to be pulled open, i.e. by manually exerting traction directly thereon.
- These and other objects are achieved by the invention by means of a retaining device of the type described above, characterised in that the hook member is mounted in the support structure such that it is movable in translation along a guided path between a retracted position and a forward position, respectively close to and remote from the appliance, and is adapted to oscillate about a moving axis at right angles to said path, the hook member being associated with resilient recall means tending to maintain it in the retracted position and in a predetermined angular rest position,
the arrangement being such that - when the door is closed the hook member engages with the retaining formation of the appliance, oscillates about the axis against the action of the resilient recall means, leaving the rest position but remaining in the retracted position, and thus enters and passes through the opening, and then oscillates, under the action of the resilient means, towards the rest position and engages with the retaining formation; and
- when the door is urged to open while the slider of the door locking device is in the rest position, the hook member, initially retained by the retaining formation, moves from the retracted position to the forward position, as a result of the relative displacement of the support structure, and oscillates about the axis against the action of the resilient recall means, becoming disengaged from the retaining formation and thus passing through and leaving the opening of the appliance.
- Further characteristic features and advantages of the invention are set out in the following detailed description, given purely by way of non-limiting example, and made with reference to the accompanying drawings, in which:
-
Fig. 1 is a perspective view of a hook device forming part of the retaining device of the present invention; -
Fig. 2 is an exploded perspective view of the hook device shown inFig. 1 ; -
Fig. 3 is a view in section along the line III-III ofFig. 1 ; -
Fig. 4 is a plan view from the top in the direction of the arrow IV ofFig. 3 ; -
Fig. 5 is a partial view in section, showing a retaining device of the present invention in the condition where the door is open and closure is imminent; -
Fig. 6 is a view similar toFig. 5 , and shows the device of the invention in the condition in which the door is closed; and -
Fig. 7 shows the device of the invention during an operation to open the door by manual traction exerted directly thereon. - In the drawings, a retaining device of the invention comprises a hook device, shown overall by 1, adapted to be secured to a door D, for instance of a domestic electrical appliance such as a washing machine, as shown, for instance, in
Fig. 5 . - The hook device 1 comprises a support structure shown overall by 2 in which a
hook member 3 projecting partially outside this structure is mounted to oscillate. - As shown in
Figs. 5 to 7 , the self-retaining device of the invention further comprises a door locking device, shown overall by 4 in these Figures. Thisdoor locking device 4 is of a type known per se, for instance of the type disclosed in European PatentsEP 0 965 677 B1 andEP 1 276 947 B1 and in the European Patent ApplicationEP 1 304 436 A1 in the name of the Applicant. - The
door locking device 4 is secured to a domestic electrical appliance A, for instance a washing machine, so that it faces anopening 5 provided in awall 6 of this appliance A. - In a known manner, the
door locking device 4 comprises aslider 7 which may move in translation (horizontally when looking atFigs. 5 to 7 ) relative to asupport housing 8 secured to thewall 6. - Again in a known manner, the
slider 7 may occupy a rest position, shown inFig. 5 , in which one of itsend openings 7a faces and is aligned with the opening 5 of the wall of the domestic electrical appliance. A helical spring 9 (Figs. 5 and7 ) tends to maintain theslider 7 in this position in which, as can be seen from the sequence ofFigs. 5 and6 , it enables thehook member 3 to be inserted through the opening 5 of the domestic electrical appliance A so that thishook member 3 may be engaged with aretaining formation 6a provided in the vicinity of theopening 5. - The methods of coupling and uncoupling of the
hook member 3 with respect to theretaining formation 6a will be described in further detail below. - With further reference to
Figs. 1 to 4 in particular, thesupport structure 2 of the hook device 1 is advantageously made from stamped plastics material and has respective substantiallyvertical eyelet slots lateral ends Fig. 2 in particular). Advantageously, the upper ends of theslots - The
support structure 2 comprises abase wall 2c in which anopening 11 is provided, through which thehook member 3 extends (seeFigs. 3 and5-7 in particular). - In the embodiment shown, the
hook member 3 has a substantially S-shaped general configuration, with anupper end arm 3a and alower end arm 3b. The latter arm acts as a hook for engagement with theretaining formation 6a of the domestic electrical appliance A. - The
end arms hook member 3 are interconnected by anintermediate portion 3c (Figs. 2 and3 ). Two opposing projecting transverse formations, shown by 12a and 12b, project from opposite sides in the upper portion of thisintermediate portion 3c. These projecting formations, which, overall, form a kind of pin of thehook member 3, are engaged in theslots support structure 2, as can be seen inFigs. 1 and4 in particular. - As it can be seen in
Figs. 2 to 4 , the proximal portions of theprojecting formations Fig. 4 in particular). - The hook device 1 further comprises a double flexion spring (double pin spring) shown overall by 13 and comprising two sections or
portions spring 13 are disposed on opposite sides with respect to the hook member 3 (Figs. 1 to 4 ) and have respectivelower arms Figs. 2-4 ) which act on thebase wall 2c of thesupport structure 2, and respectiveupper arms intermediate arm 16. As shown inFigs. 2 to 4 , theintermediate arm 16 and theupper arms double spring 13 form, overall, a kind of U which embraces theintermediate portion 3c of thehook member 3 below the projecting formations orpins relative lugs - The
spring 13 tends, overall, to maintain thehook member 3 in the retracted position shown inFigs. 1 and3-6 , in which its projecting formations orpins guide slots support structure 2. The engagement of theupper arms spring 13 with theformations relative lugs Figs. 1 and3 to 6, thehook member 3 is retained in a predetermined angular rest position. - As a result of the arrangement described above, the hook member is mounted in the
support structure 2 such that it may move in translation along a guided path defined by theslots Figs. 1 and3-6 and a forward (and rotated) position shown inFig. 7 which will be described in detail below. Thehook member 3 may also oscillate about the axis of its projecting formations orpins slots hook member 3 itself, may move along this path. - The
recall spring 13 tends, overall, to maintain thehook member 3 in the retracted position ofFigs. 1 and3-6 and in the angular rest position shown in these Figures. - With reference to
Figs. 1 and3-6 , it should also be noted that when thehook member 3 is in the above-mentioned retracted position and in the angular rest position illustrated therein, itsupper arm 3a is spaced from the upper edge of alateral wall 2d of thesupport structure 2. - The retaining device described above substantially operates as follows.
- When the door D is closed, it is brought towards the
wall 6 of the domestic electrical appliance A, as shown inFig. 5 . In this position, theend 3b of thehook member 3 engages with theretaining formation 6a. This engagement advantageously takes place at respective surfaces inclined with respect to the direction of closing of the door D towards the appliance, so that thehook member 3 consequently oscillates about the axis of its projecting formations orpins Fig. 5 , against the action of therecall spring 13. - The
hook member 3 thus enters and passes through the opening 5 of the domestic electrical appliance A and penetrates into the opening 7a of theslider 7. As soon as theend 3b of thehook member 3 passes beyond the lower edge of theretaining formation 6a of the domestic electrical appliance A, thismember 3 is caused to oscillate by therecall spring 13 into its angular rest position so that itsend 3b engages below theretaining formation 6a as shown inFig. 6 . Following this oscillation of themember 3, theslider 7 moves a certain distance in translation (towards the left starting from the position ofFig. 5 ) against the action of thespring 9. - The position shown in
Fig. 6 is a stable position, in which the door D is held, but not locked, in the closed position. - In this position, it is still possible to open the door D by exerting traction on the door D to move it away from the appliance A. When this happens, the traction applied to the door D, for instance in the direction of the arrow F of
Fig. 7 , initially causes a relative displacement of the door D and of thesupport structure 2 relative to thehook member 3 which is held by theretaining formation 6a. This relative movement is enabled by the fact that the projecting formations orpins member 3 may slide in therespective guide slots recall spring 13. - After a certain relative displacement between the
support structure 2 and thehook member 3, thewall 2d of the structure comes into abutment against theend 3a of the hook member. From this position, the subsequent displacement of the door D and thesupport structure 2 in practice causes thehook member 3 to oscillate (in the anticlockwise direction looking atFig. 7 ) about itspin formations spring 13. As a result of this oscillation, theend 3b of thehook member 3 is disengaged at a certain point (Fig. 7 ) from theretaining formation 6a and passes through and leaves theopening 5 of thewall 6 of the appliance A enabling the door D to return to the open position. - As described above, it is therefore possible to "pull" the door D open while the
slider 7 of the door locking device is in the rest position. - When, however, the
slider 7 is locked in the position ofFig. 6 , with the door closed, the door D can no longer be opened, as the lower end of thehook member 3 can no longer perform the oscillation needed to enable its disengagement from theretaining formation 6a. - The solution of the invention as described above enables the use of standard door locking devices, of the types currently in use.
- A further advantage of the solution of the invention lies in the resilient thrust exerted by means of the
spring 13 which opposes, with appropriate pre-loading, the thrust of the seal associated with the door of the domestic electrical appliance, ensuring appropriate mechanical sealing of the system. - The door may be "pulled" open by rotating the hook member, as a result of which the opening force is not affected.
- The device of the invention is particularly suited to use in washing machines, of both the top-loading and front-loading types. In the case of the latter machines, the device of the invention is particularly advantageous in so-called "large door" applications in which emergency opening of the door from inside has to be possible.
- Without prejudice to the principle of the invention, its embodiments and structural details may obviously be widely varied with respect to those described and illustrated without thereby departing from the scope of the invention as set out in the accompanying claims.
