[0001] The present invention relates to dishwasher baskets, and in particular to a dishwasher
basket with foldable plate-holding racks.
[0002] It is known that dishwasher baskets are made from lengths of steel wire welded together
and covered by a plastic coating, and the basket structure may be adapted to different
functions. At least one of the dishwasher baskets, usually the lower basket, includes
one or more rows of substantially vertical supporting rods intended to hold and space
apart the plates. This structure is effective and efficient for washing the plates,
but it makes difficult to use the basket for washing pots, pans and the like.
[0003] In order to prevent this drawback, the plate-holding supports may be connected together
so as to form a removable rack. Once the rack has been removed, the basket bottom
is an empty plane suitable for placing pots thereon. However, this solution has the
drawback that when the rack (which is quite bulky) is not being used it must be stored
somewhere outside the dishwasher.
[0004] A second solution is to connect a row of vertical plate-holding supports by means
of a horizontal rod which can rotate about its axis. This connecting rod has at least
one end stop allowing to lock its rotation when the supports are in the vertical position.
When the stop is disengaged through a roto-translational movement, the rod can rotate
to take the supports to a substantially horizontal position so as to obtain an empty
plane without removing the rack from the basket.
[0005] Also this second solution yet has some drawbacks. In fact, the movement of the stop
disposed at the end of the connecting rod is defined by a "track" formed in a plastic
insert which is mounted on the metallic structure of the basket. This implies the
manufacturing of a separate member to be subsequently mounted on the basket, thus
resulting in an increase in cost and labour. Moreover, said insert may come off the
basket or it may become a site of accumulation of dirt which makes difficult the movement
of the stop.
[0006] Therefore the object of the present invention is to provide an improved basket suitable
to overcome the above-mentioned drawbacks.
[0007] This object is achieved by means of a basket having the characteristics disclosed
in claim 1.
[0008] The main advantage of the improved basket according to the present invention is that
the stop-guiding track is also made from steel wire and integrated in the basket structure.
This allows a reduction of the manufacturing and assembly costs, and furthermore the
risk of the track coming off the basket is eliminated.
[0009] A further advantage of the present structure is that the track can not become a repository
of dirt, thus assuring a greater reliability.
[0010] These and other advantages and characteristics of the basket according to the present
invention will be clear to those skilled in the art from the following detailed description
of an embodiment thereof, with reference to the annexed drawings wherein:
Fig.1 is a schematic perspective view of a basket according to the present invention with
the plate-holding rack folded on the horizontal plane; and
Fig.2 is an enlarged detail of the basket of fig.1, showing the movement for disengaging
the stop from the locked vertical position.
[0011] Referring to fig. 1, there is shown a dishwasher basket formed by a structure of
steel wire as previously mentioned. The right portion of said basket structure has
the conventional scheme with a pair of horizontal longitudinal wires 1 having vertical
ends 2 welded to wires 3 which form the peripheral edge of the basket. These longitudinal
wires 1 are supported by transverse wires 4 of similar configuration, and carry two
parallel rows of vertical rods 5 acting as plate-holding supports so as to form a
plate-holding rack.
[0012] On the contrary, the left portion of the basket is provided with foldable racks.
These racks consist of supporting rods 5' welded to rotatable connecting rods 1' having
C-shaped ends 2 facing inwards. At the positions where the connecting rods 1' rest
on the transverse wires 4, the latter have stiffening projections 6 to the right and/or
to the left of said rods 1'.
[0013] As better seen in the enlarged detail of fig.2, each end 2' acts as a stop for the
relevant connecting rod 1' by engaging a shaped locking member 7. Said member 7 is
integrated in the basket structure, since it is made from steel wire and welded to
the peripheral wires 3. The shape which defines the guiding track for stop 2' consists
of two vertical opposite U-shaped loops, namely a lower loop 8 open downwards and
an upper loop 9 open upwards.
[0014] The mutual distance and the depth of the two loops 8 and 9 are such that in the situation
of the plate-holding rack locked in the vertical position, as illustrated with continuous
lines, a horizontal end portion 10 of stop 2' abuts on the bottom of the upper loop
9 while rod 1' passes through the lower loop 8. In this way, two points of reaction
are provided and any force applied to the supporting rods 5' does not cause a rotation
of the plate-holding rack.
[0015] In order to fold the plate-holding rack to a substantially horizontal position, as
shown with dotted lines, it is sufficient to disengage stop 2' by lifting it (arrow
A) until the end portion 10 comes out from loop 9 and then rotate it clockwise (arrow
B). It is clear that the lower loop 8 must be sufficiently deep as to allow the disengagement
of stop 2' from the upper loop 9 before rod 1' reaches the bottom of the lower loop
8.
[0016] Obviously, the movement to take back the rack from the horizontal position of fig.1
to the vertical position of fig.2 is the reverse of the one described hereinabove.
[0017] It is clear that the above-described and illustrated embodiment of the improved basket
according to the invention is just an example susceptible of various modifications.
In particular, the exact shape of the locking member 7 and of stop 2' may be changed
according to the needs, as long as they remain integrated in the basket structure.
1. Dishwasher basket made from steel wire (1, 2, 3, 4, 5) and including at least two
rows of substantially vertical supporting rods (5') acting as a plate-holding rack,
the rods (5') of each row being connected through a horizontal rod (1') rotatable
about its axis and provided with at least one end stop (2') suitable to lock its rotation
when said rods (5') are in the substantially vertical position, said connecting rod
(1') being rotatable so as to take said rods (5') to a substantially horizontal position,
characterized in that the movement of said end stop (2') is defined by a shaped locking
member (7) also made from steel wire and integrated in the basket structure.
2. Dishwasher basket according to claim 1, characterized in that the stop (2') has the
shape of a C facing towards the inside of the basket and the locking member (7) has
