[0001] This invention relates to a device for hinging a door of a built-in household electrical
appliance, such as an upright refrigerator, to a door panel of a furniture item housing
the door panel, the door panel being in a position corresponding with said door.
[0002] In the case of a built-in household electrical appliance it si desirable and necessary
to achieve maximum utilization of the space in the furniture item housing the appliance.
[0003] There are various known methods of achieving this and allowing easy opening both
of the door panel of the furniture item and of the door of the appliance (or of each
door with which it is provided and each door panel relative to it).
[0004] For example a double-parallelogram hinge is known which on opening the door panel
of the furniture item causes this panel to undergo an initial movement parallel to
itself so as to separate it from the door of the appliance (for example an upright
refrigerator), after which it allows both the door panel and the refrigerator door
to rotate about relative hinging points.
[0005] Although this method achieves optimum utilization of the furniture item housing the
refrigerator, it has various drawbacks including a high cost which negatively affects
the cost of assembling the furniture item containing the appliance (for example a
kitchen furniture unit); in addition the hinge is of considerable overall dimensions,
involving obvious storage and installation problems.
[0006] It is also known to use two separate hinges for opening the refrigerator door and
the door panel of the furniture item. This method does not however achieve optimum
utilization of the space in the furniture item housing the appliance.
[0007] An object of the present invention is to provide a device of the aforesaid type which
is of simple, low-cost construction and allows maximum utilization of the space housing
the appliance.
[0008] This and further objects which will be apparent to the expert of the art are attained
by a device in accordance with the accompanying claims.
[0009] The present invention will be more apparent from the accompanying drawing, which
is provided by way of example and in which:
Figure 1 is a schematic perspective view of a household electrical appliance built
into a furniture item, these latter comprising doors and door panels connected together
by the device of the invention;
Figure 2 is an exploded partial perspective view of the device according to the invention;
Figures 3 to 5 are schematic sections on the line 3-3 of Figure 1 showing different
stages in the use of the device according to the invention.
[0010] Said figures show a built-in upright refrigerator positioned within a furniture item,
for example a kitchen unit, and provided with doors 3 and 4 in positions corresponding
with usual preservation compartments of the appliance. The furniture item 2 comprises
three walls 5, 6 and 7 defining a compartment 3 housing the refrigerator 1; this compartment
is closed on its free side by door panels 10 and 11 in positions corresponding with
the appliance doors 3 and 4.
[0011] Each door panel is connected to the relative door by a hinging device 13 according
to the invention.
[0012] This latter comprises a body 14 fixed, in known manner, on one side 14A to the wall
5 of the furniture item 2 and on another side 14B to the refrigerator cabinet 15 (alternatively
the body 14 can be fixed to the furniture item or to the appliance). The body 14 comprises
at least one projecting flange 17 (two superimposed in the figures); with that flange
close to the refrigerator door there is associated a pin 18 arranged to cooperate
with the door 3 or 4 of the refrigerator 1, to form a hinge to enable said door to
open and close.
[0013] The pin 18 extends perpendicularly from the lower face 20 (with reference to Figure
2) of the flange 17.
[0014] With the body 14 there is associated a guide projection 21 projecting from a face
22 of its side 14A. This projection is arranged to cooperate, in order to guide its
movement along the face 22, with a terminal element 23 of a hinging member 24 by means
of a screw (not shown) enabling this member and said body to be associated with each
other in an adjustable manner. For this purpose the screw is arranged to cooperate
with a slot 28 provided in the element 23 and with a hole 29 provided in the guide
projection 21.
[0015] The hinging member 24, which is preferably a usual furniture hinge used in the furnishing
field, comprises a known elastic return element 30 (comprising for example an elastic
strip or an articulated quadrilateral of known construction and form) associated with
a terminal member 31 fixed to the door panel 10 or 11. The return element 30 enables
the door panel 10 or 11 to open and close automatically without the aid of the user,
when the door panel exceeds a dead point during its movement (for example as shown
in Figure 4).
[0016] Each door panel 10, 11 also comprises an outer face 22 (with respect to the compartment)
on which there is preferably provided a handle, board or the like 34, and an inner
face 35 facing the corresponding refrigerator door. The inner face 35 supports a substantially
L-shaped guide 38 arranged to slidingly cooperate with a slide (of complementary form)
fixed to the refrigerator door. Finally, this latter supports usual seal elements
40 and an inner liner 41.
[0017] It will now be assumed that the refrigerator 1 is to be used by opening its door
3.
[0018] By pulling the handle 34 of the door panel 10, the door 3 is opened by rotating the
door panel about the member 24 and specifically about usual hinging points (not shown
but schematically indicated by 100 in Figures 4 and 5). This movement drags the door
3 open by the cooperation between the guide 38 and the slide 36. The door rotates
about the pin 18 shown in the figures (and about an analogous pin of a device 13,
not shown, provided at the bottom of the door 3) to open and provide access to the
preservation compartment closed by said door.
[0019] The door 3 and the corresponding door panel are closed by operating in the opposite
manner.
[0020] It should be noted that opening the door panel 10 causes it in known manner to initially
separate from the wall 5 of the furniture item 2 (see Figure 4) to allow easy opening
of the door 3; in contrast when the door panel 10 is reclosed it becomes positioned
in proximity to said wall (see Figure 3) to result in perfect sealing of the door
3 against the refrigerator cabinet 15.
[0021] The device 13 is of simple construction and of considerably less cost than analogous
known devices, this deriving in particular from the use of a hinging member 24 of
wide commercial use in the furnishing field.
[0022] A particular embodiment of the invention has been described.
[0023] Other embodiments are however possible in the light of the aforegoing description
(such as providing the body 14 with only one flange 17) without leaving the scope
of the present document.
