Receiving device for receiving a food or drink component
in a food or drink preparation machine
The present invention relates to a receiving device which is constructed for
receiving at least
one food or drink component and is provided for or received in a food or drink
preparation
machine, particularly for preparation of a beverage and/or a meal in a galley
of an aircraft. In
addition, the invention relates to a food or drink preparation machine, which
is provided
particularly for an aircraft galley, with a receiving device.
State of the art
Current food and drink preparation machines for preparation, in portions, of a
beverage
and/or a meal such as, for example, a soup are designed in such a way that
they comprise a
receiving device for receiving a receptacle or a container with at least one
food or drink
component received therein. The receiving device is frequently designed as a
support
device which is withdrawable from the food or drink preparation machine and
which, after
unlocking of the support device by manual actuation of a rotary slide or a
lever of the food or
drink preparation machine, can be pulled or moved at least partly out of a
housing of the food
or drink preparation machine. After the receptacle or the container with the
food or drink
component received therein has been placed in the pulled-out or moved-out
support device
the support device is pushed or moved into the food or drink preparation
machine and
subsequently locked in the pushed-in position by manual actuation of the
rotary slide or lever
of the food or drink preparation machine.
If this rotary slide or lever is not completely transferred to its locked
position then the support
device can loosen, particularly due to shaking or shock, and move out of the
food or drink
preparation machine without user actuation. If the food or drink preparation
machine is
configured for preparation of the beverage and/or the meal by means of
supplying hot water
under pressure it is particularly dangerous if the support device is not fully
transferred to the
locked position. Known mechanical locks which guarantee secure locking require
operation
by two hands and/or significantly detract from the visual appearance of the
food or drink
preparation machine.
CA 2999742 2019-10-01

Known electrically actuated locks or sensors for detecting the locking state
are susceptible
to fault and are maintenance-intensive. These problems are of particular
concern when
the food or drink preparation machine has to be used in an aircraft, in which
on the one
hand very high safety requirements apply, but on the other hand only a small
amount of
space is available and cabin crew very often have to operate the food or drink
preparation
machine under a high level of time pressure.
Disclosure of the invention
The present invention therefore has the object of providing for a food or
drink preparation
machine a receiving device for receiving at least one food or drink component,
which can
guarantee simple recognition of insecure locking and thus guarantee secure
locking during
the food or drink preparation and at the same time can prevent uncontrolled
movement out
of the support device in the case of insecure locking. In addition, the
intention is that a
secure receiving device of that kind does not detract from the visual
appearance of the
food or drink preparation machine.
The object of the present invention is fulfilled by a receiving device as
presented below.
The receiving device is constructed for receiving at least one food or drink
component and
is provided for a food or drink preparation machine or received therein. The
food or drink
preparation machine is provided for preparation of a beverage and/or a meal,
particularly
in a galley of an aircraft. The receiving device includes a housing, a support
device
constructed for reception of a food or drink component, a locking and guiding
mechanism
and a front panel for actuation of the locking and guiding mechanism. The
support device
is movably mounted in the housing, is movable in guided manner out of the
housing with
respect to a front side of the receiving device from a moved-in end position
to a moved-out
end position, and is transferrable by the locking and guiding mechanism to a
fixing state, a
securing state or an unlocking state. The locking and guiding mechanism is
constructed in
the fixing state to fix the support device in the moved-in end position
relative to the
housing, in the securing state to block uncontrolled movement out of the
housing of the
support device arranged in a securing position, and in the unlocking state to
allow
movement of the support device out of the housing section. The locking and
guiding
mechanism is constructed to move the support device in guided manner relative
to the
housing in reaction to application of force to the support device. The front
panel is
arranged to be movably mounted at the front side of the receiving device, in
particular at
CA 2999742 2018-03-29

the support device. In addition, the locking and guiding mechanism is
constructed to transfer
the support device from the fixing state to the securing state by a first
external force applied
in a first predetermined direction to the front panel and from the securing
state to the
unlocking state by a second external force subsequently applied to the front
panel in a
second predetermined direction different from the first predetermined
direction. Moreover,
the receiving device is so constructed that the front panel in the fixing
state protrudes less
from the support device than in the securing state and the unlocking state.
The locking and
guiding mechanism is constructed to automatically restore the support device
to the securing
state if directly after reaching the unlocking state no third external force
is applied to the front
panel for drawing out the support device.
By applied external force a force is understood which is applied at least
indirectly to the
support device, especially directly to the front panel arranged at the front
side of the receiving
device, by a user present at the front side of the receiving device, thus
externally with respect
to the receiving device. The applied external force is converted by the
locking and guiding
mechanism into a guided translational and/or rotational movement of the
support device
together with the front panel and/or a movement of the front panel relative to
the support
device. The applied external force is an externally applied force.
A precondition for this guided movement and the transfer of the support device
to another
state is that the respective external force is applied to the front panel in a
respective
predetermined direction. The predetermined direction of the first external
force and the
predetermined direction of the second external force are different from one
another, at least
by an angle of 70 degrees, and are preferably opposite to one another. For
preference, the
predetermined direction of the first external force corresponds with the
direction of movement
out of the support device and/or is directed upwardly, thus opposite to the
direction of
gravitational force. The predetermined direction of the first external force
can change in
accordance with a predetermined directional path. If, for example, the front
panel is rotatably
mounted on the support device, the predetermined directional path corresponds
with a
rotational movement of the front panel from the position of bearing against
the support device
to the position protruding from the support device. The predetermined
direction of the
second external force is preferably oriented transversely to the direction of
movement out of
the support device, with a maximum difference of 30 degrees. The predetermined
direction
CA 2999742 2019-10-01
' 84211566
3a
of the second external force is preferably oriented downwardly, thus in the
direction of
gravitational force, when the predetermined direction of the first external
force corresponds
with the direction of movement out and/or upward direction. By virtue of the
different
predetermined directions the second external force can
CA 2999742 2019-10-01
4
be applied directly, thus without a predetermined minimum delay in time,
consecutively to
the first external force.
By uncontrolled movement out there is understood a movement out of the support
device -
without application of force to the receiving device by a user - due to
gravitational force or
due to shock and shaking such as occurs, for example, during operation of an
aircraft. An
controlled movement out requires a user of the receiving device to apply the
second
external force to the support device, particularly to the front panel, from
the front side of
the receiving device so as to transfer the support device from the securing
state to the
unlocking state and subsequently the user pulls the support device in the
unlocking state
out of the housing. The second external force is preferably at least ten times
greater than
the weight force of those components of the receiving device which are movable
out of the
housing thereof in the unlocking state.
In the case of the presented receiving device an insecure locking of the
receiving device,
which has been produced by, for example, unintended contact of a person with
the front
panel, can thus be very simply recognised visually and by touch in that in the
case of an
insecure locking the front panel protrudes from the support device and only in
the case of
a secure locking, thus in the case of fixing of the support device in the
moved-in position,
does the front panel bear as closely as possible or most tightly against the
support device.
In addition, the locking and guiding mechanism precludes uncontrolled movement
out of
the support device.
Insecure locking or unintended unlocking is also prevented by the fact that
the support
device of the presented receiving device is transferrable to the unlocking
state only by
application of the second external force which follows the first external
force in terms of
time and has a direction different from the first external force, to the front
panel.
Since the front panel in the fixing state neither juts out from the support
device nor is
deflected or pivoted out from this, but bears tightly against the support
device, the visual
appearance of a food or drink preparation machine provided with the presented
receiving
device is not impaired.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism is constructed for guided translational and/or rotational
movement of
CA 2999742 2018-03-29
5
the support device from the fixing state to the securing state in reaction to
the first external
force applied to the front panel, wherein the rotational movement is formed by
a rotation of
the support device through a first predetermined angle of preferably 1 to 20
degrees,
particularly preferably 2 to 10 degrees, very particularly preferably from 3
to 7 degrees.
The first external force is applied by a user who, for example, engages with
one hand
behind a lower section of the front panel and pulls the front panel in order
to thereby
produce an upwardly directed rotational movement of the front panel.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism is constructed for guided translational and/or rotational
movement of
the support device from the securing state to the unlocking state in reaction
to the second
external force applied to the front panel, wherein the rotational movement is
formed by a
rotation of the support device through a second predetermined angle of
preferably at least
3 degrees, particularly preferably at least 5 degrees. This rotation through
the second
predetermined angle is in the same direction as the rotation through the first
predetermined angle. Through the first and second external forces applied in
succession
to the front panel the support device is thus rotated relative to the housing -
in the
transition from the fixing state to the unlocking state - in total by the sum
of the first and
second predetermined angles with respect to the position in the fixing state.
The second
external force is applied by a user who, for example, presses by one hand
against the front
panel and/or support device in downward direction, thus in the direction of
gravitational
force.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism is constructed to restore the support device automatically,
for example
by means of a spring force device of the locking and guiding mechanism, to the
securing
state if directly after reaching the unlocking state there is no application
of a third external
force to the front panel for drawing out the support device. The third
external force has to
be applied by the user in a predetermined direction oriented in the direction
of movement
out of the support device. The predetermined directions of the second and
third external
forces differ from one another, preferably by at least 60 degrees.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism is constructed for guided translational and/or rotational
movement of
the support device from the securing state to the fixing state in reaction to
a fourth external
CA 2999742 2018-03-29
6
force, which is applied to the front panel, particularly in the direction of
movement of the
support device into the housing, together with a movement of the front panel
relative to the
support device. The fourth external force is applied by a user who presses
from the front
side of the receiving device against the front panel in order to produce a
rotational
movement of the front panel, which is opposite to the rotational movement of
the front
panel produced by the first external force.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism comprises a first guide device for guidance of the support
device
relative to the housing along a predetermined first guide path with a first
guide path section
associated with the fixing state and the securing state and a second guide
path section
associated with the unlocking state. For preference the first and second guide
path
sections span an obtuse angle at their transition. For preference, at least
the second
guide path section extends rectilinearly.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism is constructed for blocking a movement of the front panel
relative to
the support device in the unlocking state. As a result, the application of
force, which is
required for movement of the support device into the unlocking state, of a
user is reduced,
because an external force applied by a user to the front panel is converted as
fully as
possible into a movement in or movement out of the support device.
In a development of the presented receiving device it is provided that the
locking and
guiding mechanism is constructed for transforming a movement, in particular a
rotational
movement, of the front panel relative to the support device into a guided
translational
and/or rotational movement of the support device. Thus, it is possible by
means of a
rotational movement of the front panel to raise the support device from the
securing
position to the moved-in end position and by means of an opposite rotational
movement of
the front panel to lower the support device from the moved-in end position to
the securing
position.
In an enhancement of the above development it is provided that the locking and
guiding
mechanism comprises a force deflecting device which is rotatably secured to
the support
device and which is formed as, in particular, a rocker arm and is rotated by
the movement,
in particular rotational movement, of the front panel. The force deflecting
device designed
CA 2999742 2018-03-29
7
as a rocker enables a force-saving coupling of a rotational movement of the
front panel
with a movement of the support device, which is particularly advantageous for
single-
handed operation of the presented receiving device.
In an enhancement of the above enhancement it is provided that the locking and
guiding
mechanism comprises a second guide device for guidance of a section of the
force
deflecting device along a predetermined second guide path, which is associated
with the
unlocking state, and for fixing the protruding position of the front panel by
the force
deflecting device.
A development of the presented receiving device is, moreover, provided with a
spring
force device for providing a force for retaining the support device in the
securing position.
As a result, an uncontrolled movement out of the support device in the
securing state is
avoided or at least limited. Alternatively or optionally the spring force
device is constructed
for providing a force for reinforced fixing of the support device in the moved-
in end
position. The support device can thereby also be securely held in the fixing
state even in
the case of large external forces.
A development of the presented receiving device is designed for external loads
of the
support device in the moved-out end position of at least 1,000 Newtons. Safer
operation
of the receiving device in aircraft is thereby made possible. The receiving
device is not
damaged if due to the turbulence a member of the cabin crew supports himself
or herself
on the fully moved-out support device or impinges on this by a part or his or
her body.
A development of the presented receiving device is constructed to be free of
electrics and
electronics. As a result, a high level of security against failure and a
lengthy maintenance-
free service life of the receiving device is made possible.
In a development of the presented receiving device is provided that the
receiving device
comprises a fluid feed device for providing a fluid, particularly water or
steam, or can be
coupled with this. In addition, it is provided the receiving device is
arranged and
constructed for reception of the fluid provided by the fluid feed device and
for feeding the
fluid to the support device, particularly to a food or drink component
received therein, only
in the fixing state.

The object of the present invention is also fulfilled by a food or drink
preparation machine
provided with the presented receiving device or one of its developments and
enhancements. The food or drink preparation machine is provided particularly
for a galley
of an aircraft.
In a development, the presented food or drink preparation machine is provided
with a
surface section which is arranged on a front side of the food or drink
preparation machine
and in which the front panel of the receiving device is integrated, wherein
the front panel in
the securing state protrudes from the surface section and in the fixing state
does not
protrude from the surface section. It is thereby ensured that insecure locking
can be
readily recognised visually and by touch. Moreover, the front panel in the
fixing state does
not detract from the visual appearance of the food or drink preparation
machine.
The invention embraces any combinations of the developments presented above.

Embodiments of the invention
The receiving device 1 schematically illustrated in Fig. 1, Fig. 2 and Fig. 3
comprises a
housing 2, a support device 3, a front panel 4 and a locking and guiding
mechanism with
the components 12 to 33. A side wall section 2a of the housing 2 is
illustrated in
transparent form in Fig. 1, Fig. 2 and Fig. 3 for better illustration of the
form and
arrangement of the support device 3 and the locking and guiding mechanism of
the
illustrated embodiment, these being arranged at least partly in the housing 2.
The support device 3 is, by way of example, of multi-part construction
consisting of a
support device base body 3A and a support device front body 3B, which are
rigidly
connected together. The support device base body 3A has at least one recess
(not
shown) for reception of at least one food or drink component, which recess is
designed for
receiving receptacles such as, for example, a container with a food or drink
component
received therein. The support device front body 3B is mounted on the end of
the support
device base body 3A towards the front side of the receiving device 1. In Fig.
1, Fig. 2 and
CA 2999742 2018-03-29
10
Fig. 3 the front side of the receiving device 1 is disposed in each instance
in the side
section on the left. A rotary bearing 11 is provided at the support device
front body 3B.
The front panel 4 is attached by the rotary bearing 11 to the support device
base body 3A
of the support device 3 to be rotatable within a predetermined angular range.
For better capability of illustration, only the locking and guiding mechanism
arranged on
the righthand side of the support device is illustrated in Fig. 1, Fig. 2 and
Fig. 3. For stable
and secure guidance of the support device 3 the locking and guiding mechanism
is
provided at the righthand side and at the lefthand side (not shown in Figures
1 to 3) of the
support device 3. The locking and guiding mechanism in the illustrated
embodiment
comprises - for each of the righthand and lefthand sides respectively - a
lever arm 12, a
contact roller 14, a force deflecting device 16 formed as a rocker, a first
guide device 18
with a guide roller 20, a second guide device 21, a rotary support 23, a
rotary bearing 24, a
spring-force device 33, and a withdrawable guide rail 25. However, in
departure from the
illustration the locking and guiding mechanism can also be provided at one
side, for
example only on the righthand or lefthand side, and/or centrally.
One end of the lever arm 12 is so attached to the front panel 4 that a
rotational movement
of the front panel 4 is converted into a rotational movement or pivot movement
of the lever
arm 12. A rotatably mounted contact roller 14 is attached to the other end of
the lever arm
12 remote from the front panel 4. The contact roller 14 is so arranged and
dimensioned
that at least in the fixing state and in the unlocking state it is in
permanent mechanical
contact with the force deflecting device 16.
The force deflecting device 16 is formed as a rocker and is rotatably attached
to the
support device front body 3B by a rotary joint 17. A lever arm 16A, which
faces the front
panel 4, of the force deflecting device 16 is so constructed and arranged that
it is in the
afore-mentioned mechanical contact with the contact roller 14. The lever arm
16B remote
from the front panel 4 is provided with a guide pin 27, the position or
movement of which is
guided by the second guide device 21.
The rotary support 23 of the locking and guiding mechanism is rotatably
attached to the
inner side of the side wall section 2A of the housing 2 by the rotary bearing
24. The rotary
support 23 is mechanically coupled to the support device base body 3A by way
of the
CA 2999742 2018-03-29
11
withdrawable guide rail 25. Through the arrangement as described above and
mechanical
coupling of the rotary support 23, the rotary bearing 24, the withdrawable
guide rail 25 and
the support base body 3A, the support device 3 is translationally and
rotationally movable
relative to the housing 2 and can be moved out of and moved into the housing
2.
The locking and guiding mechanism is provided with the first guide device 18
and the
guide roller 20 for guidance of the translational and rotational movement of
the support
device 3 relative to the housing 2.
The guide roller 20 is attached to the support device base body 3A to be
rotatable about
an axis of rotation and is movable along a first guide path 19 predetermined
by the first
guide device 18. The first guide device 18 is, as shown in Fig. 1, Fig. 2 and
Fig. 3, formed
as a material recess or as a through-hole in the form of a wide, angled slot
in the side wall
section 2a. The first guide path 19, which is predetermined by the first guide
device 18, is
composed of a first guide path section 19A associated with the fixing state
and the
securing state and a second guide path section 19B associated with the
unlocking state.
The second guide path section 19B extends rectilinearly and is not curved. The
guide
path sections 19A and 19B include, at their transition, an obtuse angle of
preferably more
than 100 degrees. The translational and/or rotational movement of the support
device in
the unlocking state, thus movement of the support device out of or into the
housing, is
predetermined by the guide roller 20 guided along the second guide path
section 19B. As
illustrated in Fig. 1, Fig. 2 and Fig. 3, the second guide path section 19B
extends not
horizontally, but with a constant negative gradient from the transition to the
unlocking state
up to the moved-out end position. The moved-out end position of the support
device 3 is
defined by an end, which faces the front side of the receiving device, of the
second guide
path section 19B.
The second guide device 21 of the locking and guiding mechanism of the
receiving device
1 is constructed for guiding the guide pin 27, which is secured to the lever
arm 16B of the
force deflecting device 16 and which represents a section of the force
deflecting device,
along a predetermined second guide path 22 associated with the unlocking
state. The
second guide device 21 is, as shown in Fig. 1, Fig. 2 and Fig. 3, formed as a
material
recess or as a slot-like through-hole in the side wall section 2a. The second
guide path 22
of the second guide device 21 is formed in such a way that rotation of the
force deflecting
device 16 relative to the support device 3 during the unlocking state is
blocked. As a
CA 2999742 2018-03-29
12
result, the front panel 4 is fixed in its position protruding from the support
device 3 by way
of the contact roller 14 and the lever arm 12 in the unlocking state. As shown
in Fig. 1,
Fig. 2 and Fig. 3, the second guide path section 19B of the first guide device
18 and the
second guide path 22 of the second guide device 21, which are both associated
with the
unlocking state, are arranged as corresponding slot-like through-holes in the
side wall
section 2A to be offset parallel to one another.
A slot-like widening 26 oriented at right angles to the second guide path 22
is provided in
the side wall section 2A at the end, which is remote from the front panel 4,
of the second
guide path of the second guide device 21. The widening 26 is formed so as to
enable
rotational movement of the force deflecting device 16 about the axis 17 of
rotation thereof.
The fixing state of the support device 3 and of the locking and guiding
mechanism of the
receiving device 1 according to the invention is illustrated in Fig. 1. The
support device 3
has a horizontal disposition in the moved-in end position. The guide roller 20
is pressed
against the end of the first guide path section 19A of the first guide path 19
of the first
guide device 18. The front panel 4 lies as closely as possible to the support
device front
body 38. The contact roller 14 is in mechanical contact with the outer end
section of the
lever arm 16A of the force deflecting device 16 and blocks movement of the
force
deflecting device 16. The spring force device 33 provides a force which, when
the force
deflecting device 16 is not blocked, would lead to a rotation of the force
deflecting device
in anticlockwise sense. Due to the provided force, the lever arm 16a is
pressed more
strongly against the contact roller 14, whereby fixing of the support device 3
in the moved-
in end position is reinforced. This makes it possible for the receiving device
to also remain
securely in the fixing state if a fluid at high pressure, for example from a
fluid feed device
50 schematically illustrated in Fig. 1, Fig. 2 and Fig. 3, is applied to the
support device 3 or
to a food or drink component received therein. The guide pin 27 is located in
the widening
26 so as to allow rotation of the force deflecting device 16 and thus also
movement of the
front panel 4 relative to the support device 3 by an external force applied to
the front panel
4.
The securing state of the support device and of the locking and guiding
mechanism of the
receiving device 1 according to the invention is illustrated in Fig. 2, which
arises when a
user applies to the front panel 4 of the receiving device 1 in the fixing
state illustrated in
Fig. 1 a first external force Fl which is initially oriented in the direction
of movement out of
CA 2999742 2018-03-29
13
the support device and leads to rotation of the front panel 4 into a state
protruding from the
support device 3 as illustrated in Fig. 2, wherein the directional plot of the
force Fl
corresponds with the rotation of the front panel 4. In order to make possible
this rotation of
the front panel 4 the lever arm 16A is provided with a trough-like surface 16C
along which
the contact roller 4 is guided during rotation of the front panel 4 into the
position protruding
from the support device 3. The rotational movement of the front panel 4 in
clockwise
sense is accompanied by rotational movement of the force deflecting device 16
about the
axis of rotation of the rotatory bearing 17 in anticlockwise sense and
rotational movement
of the support device 3, to which the force deflecting device 16 is movably
attached, in
anticlockwise sense. This
rotational movement of the support device 3 through
approximately 5 degrees (see angle W1 in Fig. 2), by which the support device
3 is
lowered and inclined by comparison with the horizontal position, is guided by
the guide
roller 20, which is guided in the first guide path section 19A of the first
guide device 18.
The extent of movement is also determined by the spring force provided by the
spring
force device 33. The guide pin 27 is transferred by the movement of the force
deflecting
device 16 to the start of the second guide path 22 of the second guide device
21.
The unlocking state of the support device and of the locking and guiding
mechanism of the
receiving device 1 according to the invention in the moved-out end position is
illustrated in
Fig. 3, which state arises when a second external force F2, which urges the
support device
downwardly, is applied - subsequently to the first external force Fl - by the
user to the
front panel 4 of the receiving device 1 in the securing state illustrated in
Fig. 2. The force
F2 is thus oriented downwardly and transversely to the direction of movement
out of the
support device. The second external force F2 has to be of sufficient magnitude
to
overcome an opposing force, which is provided by the spring force device 33 in
the
securing state and which prevents further rotation of the support device
beyond the
already effected rotation of approximately 5 degrees (= angle W1), and to
transfer the
guide roller 20 from the first guide path section 19A to the second guide path
section 19B
of the first guide device 18, which at the transition together include an
obtuse angle.
Through application of the second external force F2, the support device 3 by
comparison
with the securing state is rotated, additionally to the rotation through
approximately 5
degrees (= angle W1) at the time of transition from the fixing state to the
securing state,
through approximately a further 5 degrees (= angle W2) in the same direction
of rotation.
In order that the unlocking state is maintained, a third external force F3 has
to be applied
by the user to the front panel 4 directly after application of the second
external force F2.

The third external force F3 is oriented in the direction of movement out of
the support
device 3. Without application of the external force F3, the support device 3
is restored by
the force of the spring force device 33 back to the securing state. In the
unlocking state,
the support device 3 is guided along the second guide path section 19B of the
first guide
device 18 by the guide roller 20, which is attached to the support device 3,
during
movement out or movement in. By comparison with the horizontal position of the
support
device 3 in the fixing state, the support device 3 in the unlocking state is
inclined or
lowered by the sum of the angles W1 and W2, thus by approximately 10 degrees.
The receiving device 1 illustrated in Fig. 1, Fig. 2 and Fig. 3 is intended
for use in a galley
of aircraft and is constructed for external loading of the support device in
the moved-out
end position of at least 1,000 Newtons. In addition, the receiving device 1 is
of electrically-
free and electronically-free design.
Movements of components of the embodiment of the receiving device according to
the
invention illustrated in Fig. 1 to Fig. 3 at the time of transition from the
securing state to the
fixing state are depicted by means of arrows in Fig. 4. An arrow with the
reference Px
denotes in Fig. 4 a movement of the component x on transition from the
securing state to
the fixing state. In order to transfer the locking and guiding mechanism and
the support
device from the unlocking state to the fixing state via the securing state a
fourth external
force F4 oriented in the direction of movement in of the support device has to
be applied
by a user to the front panel 4. However, the components of the receiving
device 1 are
depicted in the state illustrated in Fig. 1, thus in the already achieved
fixing state, for
reasons of simplified illustration.
Fig. 5, Fig 6, Fig 7 and Fig. 8 show an embodiment of a food or drink
preparation machine
in accordance with the invention with the embodiment, which is presented in
the foregoing,
of the receiving device according to the invention in perspective illustration
respectively in
the fixing state, the securing state, the unlocking state with incompletely
moved-out
support device and the unlocking state with completely moved-out support
device. The
illustrated food or drink preparation machine 100 is constructed as a cocoa
preparation
machine (and/or, for example, as a coffee machine and/or espresso machine),
which is
provided with the receiving device 1 presented in the foregoing. The support
device 3 of
the receiving device 1 has two recesses 60 which are each constructed for
reception of a
container (not shown) filled with cocoa milk powder (alternatively: coffee
grinds). Arranged

in the food or drink preparation machine 100 is a fluid feed device (not
shown) which is
coupled with the support device 3 or the receiving device 1 for the feed of
hot water under
high pressure only when the support device 3 is in the fixing state
illustrated in Fig. 5. The
supplied hot water is forced through a membrane or opening of the container
and
subsequently into the cocoa milk powder (alternatively: coffee grinds), which
is
(alternatively: contains) a food/drink component. The thereby-produced cocoa
milk
(alternatively: coffee liquid) is subsequently transferred from the container
to one or more
cups arranged below the support device 3.
A surface section 101 in which the front panel 4 of the receiving 1 is
integrated is arranged
on the front side of the food or drink preparation machine 100. In the fixing
state illustrated
in Fig. 5 the front panel 4 does not protrude beyond the surface section 101,
but is flush
with the surface section 101. In the securing state illustrated in Fig. 6 the
front panel 4
protrudes at an inclination from the surface section 101 and does not bear
tightly against
the support device 3. This also applies to the fixing state of the support
device 3 shown in
Fig. 7 and Fig. 8. It is additionally illustrated, by way of example, in Fig.
8 that the above-
mentioned components of the locking and guiding mechanism are respectively
provided
on the righthand side and the lefthand side of the support device.
