Definitions
- the slider 6 has a flattened shape and, as described in greater detail hereinafter, is movable between an idle position and a release position.
- the idle position is defined by the abutment of the slider edge shoulders 6A on complementarily shaped shoulders 5A of the seat, and the release position is defined by the slider abutting against the bottom 5B of the recess.
- the rotation of the control lever 15 determines the sliding of the slider 6, so as to cause the release of the hatch closure hook 7.
- the disengagement of the slider 6 from the hook 7 determines the return of the shaped plate 8 to its idle position as an effect of the thrust of a spring 23. This release is vice versa prevented if the pin 4 engages the expansion 6B of the slider, as intended during the operation of the machine.

Abstract
Description
- The present invention relates to a device for opening the front hatch of washing machines.
- As is known, the hatch of washing machines is usually opened by means of a handle-like device. This device is also adapted to prevent the hatch from opening during the operating cycle of the machine and, vice versa, the operation of the machine while the hatch is open, as prescribed by safety rules.
- Due to the usually low position of the hatch, its opening is uncomfortable since it forces the user to bend down. Devices have therefore been proposed which are capable of transferring the hatch opening control to a more adequate position, in particular by means of a pushbutton located in the control keyboard of the machine.
- The pushbutton opening devices adopted are, however, not fully satisfactory, both due to the high effort required to operate them and due to their structural complexity.
- The aim of the present invention is to eliminate the above described problem by providing a device which allows to easily open the front hatch of washing machines with a limited actuation force and with a remote control.
- Within this aim, a further object of the invention is to provide an opening device which is simple in concept, compact, economically manufactured and reliable in use.
- This aim and this object are achieved by a device for opening the front hatch of washing machines, characterized in that it comprises a body defining an engagement seat for a hatch closure hook, a slider element slideable at said seat and adapted for locking said hook, a slider actuating control lever, remotely controlled for releasing said hook, and means for opening the hatch in relation to the stopping of the machine.
- Further characteristics and advantages of the invention will become apparent from the detailed description of a preferred embodiment of the device for opening the front hatch of washing machines, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- figure 1 is a partially cutout and sectional side view of the device according to the invention in hatch opening position;
- figure 2 is a similar view of figure 1 of the device in a closing position;
- figure 3 is a longitudinal sectional view of the device in opening position;
- figure 4 is a similar view of figure 3 of the device in closing position.
- With reference to the figures, reference numeral 1 generally indicates the body of the hatch opening device. The body 1 has a
flattened portion 2 defined in front of a box-like portion 3 housing the electric controls of means for opening the hatch. Said opening means substantially comprise apin 4 for locking said device. - Longitudinally to the
flattened portion 2 of the body 1 there is arecess 5 constituting the seat for aslider element 6 adapted to engage a conventionalhatch closure hook 7, shown in broken lines in figure 2. - The
slider 6 has a flattened shape and, as described in greater detail hereinafter, is movable between an idle position and a release position. The idle position is defined by the abutment of theslider edge shoulders 6A on complementarilyshaped shoulders 5A of the seat, and the release position is defined by the slider abutting against thebottom 5B of the recess. - The
slider 6 furthermore has alongitudinal expansion 6B directed towards the box-like portion 3 and adapted to engage thepin 4. Thehook 7, in the locking step, retracts ashaped plate 8 facing theslider 6 and adapted to operate a microswitch. Theplate 8 is longitudinally and slideably mounted in the body 1, in an accommodation provided on the box-like portion 3 which extends in said sliding seat of theslider 6, so that said plate protrudes in front of the body 1. - The
slider 6 is retained in therecess 5 by means of acover 9 which is adapted to be fixed on theflattened portion 2 of the body 1. Thecover 9 is centrally provided with anopening 10 which cooperates with a corresponding opening provided on theportion 2 to define the engagement seat of said hatch closure hook. - The
slider 6 also has acentral opening 11 which, in idle position, partially engages said engagement seat, so as to lock thehook 7. The opening 10 and 11 conveniently have beveled edges 10A, 11A for easing the insertion of thehook 7. - The
opening 10 is surrounded by an enlargedborder 12, on the outer face of thecover 9, while agroove 13 is provided on the inner face and acts as guide for a corresponding enlargededge 14 of theopening 11 of the slider. - Between the
flattened portion 2 of the body 1 and thecover 9, acontrol lever 15 is articulated and is remotely actuatable for releasing the hatch. Thelever 15 is rotatable on apivot 16, defined by thecover 9 and surrounded by anannular spacer 17 adapted to provide an interspace which defines the rotation plane of said lever. - On its own rotation plane, the lever has a pair of
divergent arms 15A, 15B which are substantially at a right angle to each other. The first arm 15A has, proximate to its end, aslot 18 in which there engages apin 19 protruding from theslider 9, while thesecond arm 15B has ahole 20 for fastening a conventional traction element, conveniently connected to a pushbutton for opening the hatch arranged in an easily accessible position. It is also possible to connect the control lever to a pedal or the like. - The
lever 15 is rotatable, in contrast with aspring 21 pivoted atpin 22 and acting on thepivot 19 of the slider, between the idle position shown in the figure and a release position. - The rotation of the
control lever 15 determines the sliding of theslider 6, so as to cause the release of thehatch closure hook 7. During opening, the disengagement of theslider 6 from thehook 7 determines the return of theshaped plate 8 to its idle position as an effect of the thrust of aspring 23. This release is vice versa prevented if thepin 4 engages theexpansion 6B of the slider, as intended during the operation of the machine. - It is apparent that the stroke of the described lever assembly is very limited, with the consequent advantage of having a compact device which also requires a very limited effort to be actuated. The device according to the invention is furthermore particularly simple in construction and assembly.
- In the practical embodiment of the invention, the materials employed, as well as the shape and the dimensions, may be any according to the requirements.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.
