Description
[0001] The present invention relates to a butter compartment for a
refrigerator, in other words a compartment which is attached to a
door of a refrigerator and can be sealed with a flap.
[0002] DE 196 33 975 A1 discloses door-mounted storage compartments
for a refrigerator, which each comprise a four-sided frame that can
be anchored to a refrigerator door, and a container which is
mounted within the frame. The frame can be used with identical
dimensions of container types with different heights, and a frame
without a suspended container can also be used in order to secure
tall refrigerated products, which stand in a container which is
supported by a lower frame. This allows for a cost-effective
manufacture of the door fixtures in a refrigerator.
[0003] One disadvantage with this design principle nevertheless
consists in no suitable butter compartment previously being
available in terms of appearance.
[0004] The present invention is to remedy this failing.
[0005] This object is achieved by a door-mounted storage
compartment for a refrigerator comprising a four-sided frame that
can be anchored to a refrigerator door and a receptacle, which is
mounted within the frame, in which the frame is subdivided into a
first frame part forming at least three sides of the frame and a
second frame part which forms at least one section of a fourth side
of the frame and is connected to the first frame part so as to be
pivotable about a longitudinal axis.
[0006] This first frame part alone can represent a flap of the
container, or a flap of the receptacle can be secured to the second
frame part and is as a result pivotable.
[0007] Frames and receptacles can be manufactured from different
materials, which differ in terms of their heat expansion
coefficients. Metal such as aluminum or stainless steel can be used
for the frame for instance, while the receptacle is made of
plastic. In order to prevent parts of the door-mounted storage
compartment from buckling due to different heat expansion
coefficients, the flap and the frame part are preferably
immobilized relative to one another in the direction of the
longitudinal axis at one single point. This means that regions
between the flap and frame part, which are at a distance from this
single point, can be moved relative to one another due to different
heat expansion coefficients without stresses resulting therefrom
being able to develop therebetween.
[0008] For immobilization purposes, a pin in the flap preferably
engages in a recess of the second frame part at said point.
[0009] This sole point in respect of the longitudinal axis is
preferably arranged centrally so as to prevent significant
displacements caused by heat expansion occurring at one end of the
second frame part, and none or minimal displacements occurring at
the opposite end.
[0010] The flap can preferably be latched onto the second frame
part.
[0011] A form-fit connection is preferably provided between the
container and the first frame part adjacent to the two free ends in
each instance in order to prevent opposite free ends of the first
frame part from bending apart under the load of the receptacle and
thus no longer offering the receptacle a firm hold. Such a form-fit
connection can be formed in particular by pins pushed into flush
openings in the receptacle and first frame part, in particular
expansion rivets.
[0012] To keep the manufacture of the frame simple, the first frame
part is preferably assembled from an elongated strut and two
brackets attached to the ends of the strut and forming two corners
of the frame in each instance. This enables the strut to be
manufactured from a continuous casting profile for instance, while
the two brackets are formed for instance using plastic injection
molding or aluminum die-casting. Different frame models can thus be
easily manufactured in a manner adjusted to different widths of the
door in each instance.
[0013] A further simplification results if the elongated strut and
the second frame part have the same cross-sections. These can be
manufactured in particular from the same continuous casting
profile.
[0014] A recessed tray can be provided in a cover of the
receptacle, in order also to enable secure storage of refrigerated
products on the container.
[0015] Further features and advantages of the invention result from
the description which follows of exemplary embodiments with
reference to the appended Figures, in which;
[0016] FIG. 1 shows a perspective view of a refrigerator door with
a butter compartment according to the present invention;
[0017] FIG. 2 shows an exploded top view onto the frame of the
butter compartment;
[0018] FIG. 3 shows a vertical section through a support rail
mounted in the refrigerator door as well as a side view of a butter
compartment suspended on the support rail with a partially opened
flap;
[0019] FIG. 4 shows a section through a corner of the butter
compartment along a plane indicated in FIG. 1 with IV;
[0020] FIG. 5 shows a section through an upper edge region of the
flap, latched onto a second frame part, and
[0021] FIG. 6 shows a horizontal section through a support rail
countersunk into the door, on which the butter compartment and
further refrigerated goods carriers are suspended.
[0022] FIG. 1 shows a perspective interior view of a refrigerator
door 1. The refrigerator door is usually embodied as a hollow part
filled with insulation material comprising a hard inner wall and
outer wall. Two vertical grooves are countersunk into the inner
wall, in which a support rail 2 is mounted in each instance, as is
shown in detail for instance in FIG. 6 and is described in further
detail.
[0023] Frames 3, 4 of an essentially rectangular design are
anchored to the two support rails 2 at different heights. A square
plastic container 5 which opens upwards is suspended on the lowest
frame 3, by a circumferential lip of the container 5 resting on the
topside of the frame 3. The container 5 and its frame 3 thus form a
door-mounted storage device, which can be used in particular for
accommodating bottles.
[0024] No container is suspended on a second upper frame 3, it is
used to secure bottles positioned in the lower container 5 from
toppling over.
[0025] A container 6, the height of which is less than that of
container 4, is in turn suspended on the next highest frame 3.
[0026] The topmost frame 4 which is anchored to the door 1 is
identical to the frame 3 in terms of its external design, it has a
somewhat different structure with a first frame part 7, which forms
the two narrow sides of the frame 4 and a longitudinal side facing
the door 1 and is anchored to the support rail 2, and a second
frame part 8, which forms the main part of a longitudinal side of
the frame 4 facing away from the door 1, and is connected in a
pivotable fashion to the first frame part 1 about a longitudinal
axis 14.
[0027] The top view of FIG. 2 shows the structure of the frame 3, 4
in more detail. One of each of these frames 3, 4 includes two
die-cast side parts 9, which are mirror symmetrical in respect of
each other, upon which an adapter 10 is formed in each instance for
fastening to the support rails 2. The side parts 9 are
plug-connected to a longitudinal strut 13 and/or to the second
frame part 8 by way of pins 11 and 12. To ensure the rotatability
of the second frame part 9, the pins 12, which connect it to the
side parts 9, are arranged cylindrically in the case of the frame 4
and on the axis 14. Contrary thereto, the pins 11 have a
noncircular cross-section between the longitudinal struts 13 and
the side parts 9, or several pins are provided in each instance
between the longitudinal struts 13 and each side part 9 in order to
ensure a torque-proof connection. With the frame 3, pins connect
the side parts 9 in a torque-proof manner to two longitudinal
struts.
[0028] The side parts 9, the longitudinal struts 13 and the second
frame part 8 consist of stainless steel or preferably aluminum.
[0029] A container 15 suspended on the frame 4 takes the form of an
essentially square box with an open longitudinal side which can be
closed by a flap 16 fastened to the second frame part 8. As is
shown in FIG. 1, a shallow recessed tray 7 is formed on the upper
side of the container 15, said tray being used as an easily
accessible shelf surface for various small items.
[0030] In its position shown as closed in FIG. 1, the flap 16 is
flush with adjacent wall parts of the container 15. To enable a
user-friendly opening, it is provided on its lower edge with a bar
18 shown in FIG. 3, said bar reaching below the base of the
container 15 when the flap is in the closed position so that it can
be easily gripped in order to lift the flap 16.
[0031] Similar to container 5, container 15 also has a lip 19 on
its upper edge, this nevertheless only rests on the first frame
part 7, and not however on the second frame part 8. As apparent in
FIG. 4, openings 20, 21 are formed in the lip 19 and in the side
parts 9 adjacent to the free ends of the side parts 9 supporting
the second frame part 8 in each instance, into which openings an
expansion rivet 22 is pushed, shown in a simplified manner. After
passing through the openings 20, 21, the springy, divergent shaft
parts 23 of the rivet shaft secure the expanded rivet 22. Due to
the elastic effect of a rivet shaft, this ensures that the free
ends of the side parts 9 do not bend apart over time due to
different heat expansion coefficients of the metallic frame part 7
on the one hand and the container 15 formed from plastic on the
other hand. The dimensional stability of the first frame part 7 and
a permanently secure hold for the container 15 is thus ensured.
[0032] FIG. 5 shows a section through the second frame part 8 and
the upper part of the flap 15 attached thereto. The frame part 8
realized as a continuous casting profile has two grooves 24, 25 on
its interior facing the flap 16, which are undercut on their upper
side in each instance.
[0033] A lip 26 formed on the upper edge of the flap 16 is provided
with an upwardly directed hook 27 and, in the perspective in FIG.
5, can be inserted into the groove 24 obliquely from above. If
after the hook 27 enters the groove 24, the flap is pivoted in the
counter clockwise direction, the hook 27 engages into the undercut
of the groove 24 and hooks 28 protruding from the flap 16 below the
lip 26 meet an insertion bevel 29 of the groove 25, at which they
are elastically hinged in order finally to engage into an undercut
in the groove 25.
[0034] In order to immobilize the flap 16 on the frame part 8 also
in the longitudinal direction thereof, a bore 30 indicated by
dashed contours in FIG. 5 is formed centrally within the frame part
8. An individual pin 31 of the flap 16 engages in this bore 30. In
the event of temperature fluctuations, the regions of the flap 16
and frame part 8 lying laterally to the pin 31 and the bore 30 move
freely relative to one another. No internal stresses, which could
lead to a deformation of the flap 16, are thus formed.
[0035] FIG. 6 shows a horizontal section through a support rail 2
and a part of the inner wall of the door 1, on which it is mounted
countersunk into a groove. An external profile 40 of the support
rail 6 here has two parallel side walls 41, which are connected to
one another in an H-shape by way of a transverse bar 42. Openings 9
for receiving hooks of an adapter 10 (not shown in the Figure) are
formed at regular intervals in the transverse bar 22. The
transverse bar 42 forms the base surface of a groove 43 which is
undercut and opens toward the interior. A second undercut groove 44
is provided on the side of the transverse bar 42 engaging in the
door 1.
[0036] An input gap 45 in the groove 44 has such a width that a
shaft, but not however a head of a fastening screw 50, can pass.
Expansions 46, indicated in FIG. 6 by dashed boundary lines, are
only created in places on the input gap 45, which are wide enough
to also allow a screw head to pass. This enables the support rails
2 to be mounted to the door 1, by the screws 50 firstly being
positioned on the door 1 in accordance with the expansions 46, then
the rails 2 are inserted into the groove in the door, with the
screw heads passing through the expansions 46 and finally then the
support rail 2 in the groove is moved longitudinally so that the
screw heads are captured in the groove 44.
[0037] A pair of opposing slots are formed in the two side walls
41, in which slots is guided in a vertically displaceably fashion a
narrow slat 47. The slat 47 divides the interior of the groove 44
into a rear region accommodating the heads of the screws 50 and a
front region, which accommodates the hooks of adapters 10 which
pass through the openings 33.
[0038] The slat 47 is provided with a plurality of holes 48, which
when the slat 47 is in a lowered position lie just below an opening
33 in the transverse bar 42 and are as a result not visible from
the outside. The slat 47 can however be lifted into a position in
which the holes 48 are flush with one of the openings 33 in each
instance and through this opening 33 and the corresponding hole 48,
the head of a rear positioned screw 50 is accessible for a tool, in
order to fasten or detach the support rail 2 to/from the door 2.
During normal use of the refrigerator, closed regions of the slat
47 lie in front of the screw 50 in each instance so that none are
visible therefrom.
[0039] In respect of FIG. 3, the adapters 10 each include a
cross-sectionally T-shaped guide member 34 with a transverse bar 35
resting externally against the support rails 2 and a rib protruding
centrally from the transverse bar 35 and engaging in the undercut
groove 43 of the support rail 2. Pins 37 protruding in the opposite
directions are formed on an upper end of the rib 36, said pins each
engaging in each instance in the undercuts 39 of the groove 43. A
hook 38 protrudes from a lower end of the rib 36, said hook
engaging in an opening 33 formed on a base surface of the groove
43.
[0040] In order to change the height of the frame 4, it is
sufficient to pivot this in respect of FIG. 3 in the
counterclockwise direction so that the two hooks 38 become free
from the openings 33 of the two rails 2, while the pins 37 remain
caught in the undercuts 39 of the grooves 43. If attention is paid
during pivoting to ensure that at least the hooks 38 not leaving
the grooves 43, it is not possible due to the rigid connection
between the adapters 10 by way of the frame 4 to lift or lower one
of the adapters 10 in a significantly more forceful manner than the
other. Tilting of the frame 4 when changing the height thereof is
as a result largely ruled out.
[0041] As shown in FIG. 3, the pins 37 can have a non-circular
cross-section. It is conceivable for the pins 37 to be lengthened
in the vertical direction to such a degree that they restrict the
pivoting motion freedom of the unit from the frame 4 and support
arms 10 to such a degree that the hooks 38 are no longer able to
leave the grooves 23. For the same purpose, several pins arranged
on the same side of the rib 36 or height-adjusted in respect of
each other on opposite sides, as is shown in FIG. 6 by a dashed
outline 37, are used.
