Definitions

the present invention relates to a safety closing device for drum leaves of a washing machine.
Washing machine drum hinged door closers generally have one or more projecting hooks. These hooks present a risk for the hand of the inattentive user (hooking by the protruding part during handling of the drum) and for the linen which is introduced into or out of the drum (hooking of the buttons , loops of fabric, coins or woolen ). In addition, these closing devices are relatively unsightly.
the subject of the present invention is a device for closing the drum of a washing machine which presents practically no danger either to the user or to the laundry, while being simple and inexpensive to manufacture and relatively aesthetic.
the closure device according to the present invention of the type with two parts with mutual snap-fastening, one of which is integral with one of the leaves, and the other of the second leaf, is characterized in that one of the leaves has a convex part at least partially masking the hooks.
FIGS. 1 and 2 show one of the two leaves (leaf 1) of a drum of a washing machine.
This drum is of the top loading type, and the leaves are of the hinged type.
the free edge 2 (the one opposite the end comprising the hinge 1A) of the leaf 1 covers, in the closed position of the leaves, the free end of the other leaf 3 (FIGS. 3 to 12).
the leaf 1 is the leaf on which the user presses to lock the assembly of the two leaves, and he presses the leaf 3 to unlock the leaves.
the leaf 1 comprises, approximately at its center, a concave stamped zone 4, which has for example a shape of a semicircle, the straight edge 5 of which is closest to the free edge 2 and parallel to it.
the depth of the stamped area 4 gradually increases from the top 6 of the semi-circular part towards the straight edge 5.
the depth of this area 4 varies from approximately 5 mm at the top 6 to about 10 mm near the straight edge 5.
the length of the straight edge 5 is about half the width of the leaf 1.
This zone 4 serves as a gripping zone for bringing the closed drum, at the end of the washing and / or spinning cycle, to the position of unloading the laundry, if, for example, due to non-homogeneous distribution of the laundry in the drum, the drum stop mechanism has not worked properly, and serves as a support area for opening and closing the leaves as explained below.
zones 8 and 9 are, for example, as shown in the drawing, in the form of spherical caps whose centers 8A, 9A of the openings are located on a line 10 parallel to the rim 5 and slightly behind (towards the hinge 1A) of the latter.
the maximum depth of these zones 8 and 9 is substantially equal to the depth of zone 4 near the edge 5.
the centers 8A, 9A of the circular edges of zones 8 and 9 are each substantially equidistant from the edge closest to zone 4 and from the side edge closest to the leaf 1.
the shapes and dimensions of the zones 8 and 9 may be different from those described above, provided that these zones fulfill their role of "barrier" without harming the rigidity and the strength of the leaf 1.
the leaf 1 has another stamped zone 11 convex.
the concepts of concave and convex zones of the leaves are to be understood in the sense of zones as seen from the outside of the closed drum.
the rim of this zone 11 has for example an oblong shape whose axis is parallel to the edge 2.
the length of the zone 11 is for example, but not necessarily, substantially equal to the length of the rim 5 of zone 4, and its width is such that it allows to remain between this zone 11 and zone 4 on the one hand, and edge 2 on the other hand, non-stamped strips of the leaf having a width of at least 5 mm approximately, in order to keep the leaf 1 sufficient rigidity.
the zone 11 is advantageously centered with respect to the lateral edges of the leaf 1.
a cut is made in the leaf 1.
This cut can have the same shape and dimensions as the edge of the zone 11.
This cut is covered with a convex part which is fixed for example by riveting.
This part can be made of metal or plastic.
Zone 11 is used to accommodate one of the parts, for example the "male" part 12 of the locking device for leaves 1 and 3.
This part 12 has for example a general shape of rectangular strip, one of the large edges of which is folded at an angle of approximately 20 °, along a line parallel to its long axis, the width of the folded part being equal to approximately 1/4 of the width of part 12.
This folded edge is directed towards the inside the drum when the part 12 is fixed to the leaf 1.
the length of this strip 12 is greater than the length of the zone 11, and its ends are fixed, for example by riveting, to the non-drawn edge of the zone 11 (holes of passage 14 for the fixing rivets made in the leaf 1), so that the folded edge 13 is directed towards the interior of the machine.
the part 12 of the leaf locking device cooperates with a "female" part 15 fixed on the leaf 3, near its end.
This part 15 has for example a general shape of a rectangular strip, one of the long sides of which is bent to form a sort of gutter 16, having in section a "V" shape with a rounded elbow.
This part 15 is fixed, for example by riveting, near the free end of the outer face of the wing 3, so that in the locked position of the two leaves ( Figures 7 and 8), the edge 13 is inside of the elbow connecting the flat part of the part 15 to the flange 16.
the leaf 3 can then be released, and, without ceasing to exert sufficient pressure on the leaf 1 (by pressing on the rear part of the zone 11, that is to say on its part closest to the zone 4), the following effects are observed successively: the end of the outer face of the gutter 16 slides on the underside of the edge 13 in the direction of its end ( Figures 4 then 5). As soon as the edge of the gutter 16 exceeds the end of the rim 13 (FIG. 6), it is free to go back up, and, the gutter 16 snaps almost instantaneously with the part 13 which it comes to grip firmly (FIG. 7) . There is thus obtained a mutual locking of the two parts 12 and 15 of the leaf closing device, since any pressure applied to the internal faces of the leaf 1 and / or of the leaf 3 only reinforces this locking.
an opening is made there, and a part in the form of a bowl, metallic or made of plastic, is attached to this opening which is used to house and hide the two parts of the closing device.
the variant of the closure device shown in FIG. 13 comprises, for example on the end of the internal face of the leaf 3, under the zone 11, a part 17 having the general shape of a rectangular strip whose major axis is parallel to the axis of the drum, and the end of which bordered by the long side facing the hinge of this leaf is wound on itself to form a kind of tube 18 whose axis is in the same plane as the plane part 17.
the outside diameter of this tube 18 is for example between 5 and 10 mm approximately.
the part 19, integral with the end of the external face of the leaf 3, is in the general form of a rectangular strip whose major axis is parallel to the axis of the drum, and whose end, bordered by the large side facing the hinge of the leaf 1, is wound on itself to form a sort of gutter 20 having, in section, a semi-circular shape.
the diameter of the gutter 20 is practically equal to the outside diameter of the tube 18.
the dimensions of the parts 17 and 19 and their relative arrangements are such that in the closed state of the leaves 1 and 3 the flange 18 penetrates to the bottom of the hollow formed by the gutter 20.
the operation of this closing device is similar to that described above with reference to FIGS. 3 to 12.
FIG. 14 shows yet another variant of the leaf closure device according to the invention.
the leaf 1 carries a part 21 formed from a rectangular bar, one of the large edges 22 or both of which is folded back at an angle of approximately 120 ° according to a radius of curvature of approximately 3 to 5 mm.
the leaf 3 carries a part 23 formed from a rectangular bar (the axis of which is parallel to the axis of the drum when it is fixed to the leaf 1) of which one of the large edges is folded outwards from the leaf 3 to form a gutter 24 which comes to marry the outer face of the edge 22 in the locked position of the closure device.
the device of the invention makes it possible to perfectly hide, in the closed state of the leaves, the elements of the leaf closing device, which not only ensures a more aesthetic appearance to the closed drum, but avoids any accidental contact of the hands. the user or the laundry with the closing device when handling the drum.
