demands for further reduction of installation space and
doWnsiZing of coffee makers equipped in the galley.
SUMMARY OF THE INVENTION
DESCRIPTION OF THE RELATED ART
[0002] Conventionally, a galley Which is a service prepa
ration room for preparing food and beverage in a vehicle
such as an aircraft is designed to store food, beverage and
tableWare to be served to passengers, and is generally
equipped With coffee makers for serving hot beverages.
FIG. 5 is a perspective vieW illustrating a galley of an
aircraft capable of having a coffee maker installed therein.
The galley denoted as a Whole by reference number 50
[0007] The present inventors have noticed that the space
for housing the coffee server in the coffee maker is required
only during use of the coffee maker, and attempts to solve
the problem of the prior art by folding in the space for
housing the coffee server When the coffee maker is not in
use.
[0008]
The object of the present invention is to provide a
high rigidity and light Weight, such as honeycomb panels.

When the holder is at an ascended position in proximity to
the coffee maker body.
[0010] According to the present coffee maker, in order to
mount a coffee server, the lock mechanism is unlocked and
the sets of folding arms in folded states are extended. Since
at least tWo sets of folding arms are disposed on each side
of the coffee maker body, respectively, the holder ?xed to the
loWer end of the folding arms descend in parallel to the
coffee maker body When the arms are being extended. Thus,
a space is secured betWeen the maker body and the holder,
and a coffee server can be mounted on the holder that is held
horiZontally and stably. When the coffee maker is not in use,
the folding arms can be folded so as to approximate the

[0022] The coffee maker 1 illustrated in FIGS. 1 and 2
comprises a coffee maker body 2 ?xed to a galley and
vehicle, a ship or a camping car. In a vehicle such as an
aircraft, a railway vehicle, a ship or a camping car, not much
space is allowed to be occupied by the galley. The applica
tion of the present folding coffee maker to the galley
contributes to doWnsiZing the space of the galley While
to a galley to receive supply of hot Water for breWing coffee
from a hot-Water supply unit equipped to the galley. If the
coffee maker itself must be equipped With a heating device
for heating cold Water to make hot Water, the coffee maker
body becomes bulky, taking up too much space. Therefore,
by receiving supply of hot Water for breWing coffee from a
hot-Water supply unit equipped to the galley, the space taken

[0014] According to the folding coffee maker applied to a
galley, itis preferable to dispose the coffee maker body
slidably betWeen a draWn position at a front side of the
galley and a stoWage position at a back side of the galley. By
slidably disposing the coffee maker body betWeen the draWn
position at the front side of the galley and a stoWage position
at the back side thereof, When using the coffee maker, the
coffee maker body is pulled out to the draWn position at the
front side of the galley, and then the holder is loWered for
use. When the coffee maker is not in use, the holder is
elevated and locked onto the coffee maker body, and With the
locked status maintained, the coffee maker body is pushed
back into the stoWage position at the back side of the galley,
thereby safely stoWing the coffee maker in the galley. Even
When the coffee maker is being used, a space exists at the
back side of the compartment installing the coffee maker,
Which can be utiliZed for other purposes. When the coffee
maker is not in use, almost all the space in the compartment
can be used for other purposes.
[0015] According to the coffee maker of the present inven
tion arranged as described above, the coffee maker can be
utiliZed conveniently during use as a normal coffee maker,
but When it is not in use, the coffee maker can be folded up
and stoWed in a compact fashion. As a result, the installation
space for the coffee maker can be doWnsiZed, and the cleared
space can be utiliZed for other purposes.

The holder 4 is a shallow tray-shaped member, and
as shown in FIG. 1, has a depth shorter than the coffee
maker body 2, and is located in the front side of the body.
The Width of the holder 2 is Wider than the coffee maker
body 2, as shoWn in FIG. 2. Therefore, the mounting end 27
of the loWer arm 22 is ?xed to the inner side of the holder
4, so as to prevent pinching of hands and ?ngers When
moving the holder 4 up and doWn. As shoWn in FIGS. 1 and
2 Which illustrate the folding arms 3 in their fully extended
makers 1, 1 are disposed side by side on the loWer surface
of a shelf 41 in the galley, hung on rails R (not shoWn, refer
to FIG. 2) and capable of being draWn out toWard the front.
The folding coffee maker 1 on the left side shoWs a used
state in Which the coffee server is placed in the coffee maker,
and the folding coffee maker 1 on the right side shoWs an
unused state in Which the arms are folded in and the holder
stoWed. Since the folding coffee maker 1 has a compact
structure Without a heating device, When it is in a used state
state, a suf?cient space for mounting a coffee server 5 to the
as shoWn on the left, the compartment has a vacant space
holder 4 is formed betWeen the coffee maker body 2 and the
holder 4, alloWing the coffee server 5 to be placed in or taken
out of the holder 4 through the folding arms 3, 3 disposed on
the front side.
40a beloW and behind the coffee maker 1. When it is in an
unused state as shoWn on the right, there is a large vacant
[0027] FIG. 3 shoWs the folding arms 3 in their folded
state. By pushing up the holder 4, the holder 4 can be placed
directly beloW and in proximity to the coffee maker body 2.
In this folded state, the intermediate shaft 23 is brought up
and folded at a position above the mounting shaft 28
connecting the arm 21 to the coffee maker body 2. In order
to lock the holder 4 at this elevated position, the coffee
maker body 2 is equipped With a lock mechanism 30. The
lock mechanism 30 in this example consists of a spring plate
31 having a bent shape, and according to the illustrated
locked state, the lock mechanism comprises a ?xing portion
32 secured to the bottom surface of the coffee maker body
2, a ?rst contact portion 33 bent and extended doWnWard
from the ?xing portion 32 and capable of coming into
contact With a side surface 4a at a depth (back) side of the
holder 4, a second contact portion 34 bent and extended
sideWays from the ?rst contact portion 33 and capable of
coming into contact With a portion of a bottom surface 4b
adjacent to the side surface 4a at the back side of the holder
4, and a manipulation portion 35 bent and extended doWn
Ward from the second contact portion 34. By manipulating
the manipulation portion 35 With ?ngers, the locking and
unlocking of the lock mechanism 30 is enabled. In other
Words, by pushing the manipulation unit 35 toWard the back

Such vacant space 40a, 40b can be used effectively, for
example, for temporarily placing food, dishes or the like.
[0030] The above-described embodiment illustrates only
one possible example of the folding arms 3, and apparently,
various changes and modi?cations can be made to the
number of arms, the design thereof and so on so long as the
folding arms maintain their folding function. Similarly, the
holder 4, the rail mounts 19, the lock mechanism 30 shoWn
in FIG. 3 or the like of the embodiment are merely
examples, and apparently, various changes and modi?ca
tions can be made so long as they maintain their respective
functions to support a coffee server, to enable sliding move
ment of the coffee maker and to provide a locking mecha
nism capable of locking and unlocking the holder.
[0031] According to the above-described embodiment, the
present invention is applied to an aircraft as one example of
a vehicle, but the present invention is not limited to such
example. It is apparent that the present invention can be
applied to other vehicles such as camping cars, railWay
