The invention relates to a hinge, in particular a
single-axis hinge, having a hinge arm mountable on a
wall of a furniture unit, and at least one hinge pot,
rotatably connected to the hinge arm on the door side
and having a recess into which an inner coupling part
may be inserted and in which the latter is releasably
anchorable by means of a locking part, acted upon by a
spring, in the hinge pot, a clamping screw furthermore
being provided.
Such hinges are used in particular in the construction
of office, organizational and functional furniture.
They are used as corner and twin hinges, i.e. hinges to
which two doors are jointed.
In general, they are made as single-axis hinges, but
success is not to be restricted thereto.
In the case of conventional hinges, a baseplate is
secured to the side wall of the furniture unit when the
latter is assembled. A hinge pot is set in the door.
This hinge pot is connected to the actual hinge arm via
an articulated spindle or four articulated spindles and
two articulated levers. In the final assembly, the
hinge is placed on the baseplate, which is mounted on
the side wall of the furniture unit, and connected to
this baseplate. The position of the door can be
~/~
2 ;~037~13
adjusted by relative displacement of the position of
the hinge arm with respect to the baseplate. In
general, conventional hinges provide the possibility of
adjustment in the direction of the width of the
furniture door joint and the depth of the furniture
unit. In some cases, height adjustment is also
possible.
Hinges of the type mentioned at the outset differ from
the said hinges in that the hinge arm is secured
directly to the side wall of the furniture unit, for
example is screwed thereto. This has the advantage that
it can be kept very narrow, and further space is saved
by the omission of an additional baseplat. The entire
width of the furniture unit may be used to the optimum
as a result, this being particularly useful for example
with index card files or the like.
With these hinges, two-part assembly is also known;
i.e. the hinge arm is secured to the side wall of the
furniture unit and a hinge pot is set in the door. When
the door is finally hung, the hinge pot is connected to
the hinge arm via a coupling part jointed to the hinge
arm. In the case of conventional hinges, this is done
by means of a clamping screw.

It is the object of the invention to improve a hinge of
the type mentioned at the outset such that hanging of
the door, i.e. connection of the hinge pot to the
coupling part, is facilitated. Here, it should be
possible for hanging to take place without tools, since
tightening of the clamping screw often poses
difficulties if the door has to be held. Similarly, in
accordance with the invention it should be possible to
take the door off again easily, i.e. to separate the
hinge pot from the hinge arm. It is a particular object
of the invention to make coupling of the hinge pot and
the coupling part possible in any position of the
hinge.
The object according to the invention is achieved in
that there is provided in one of either the hinge pot
or the coupling part at least one shoulder which is
received with form fit in a recess of the other part,
the coupling part being insertable in the hinge pot
perpendicular or approximately perpendicular to the
plane of the door, and in that the locking part, which
is mounted tiltably on the coupling part, bears against
a nose of the hinge pot wall delimiting the recess.
Advantageously, it is provided for the shoulder and the
recess to have diverging side faces. This simplifies
insertion of the coupling part in the hinge pot.

In order to be able to release the coupling part from
the hinge pot easily, advantageously it is provided
that a lever is mounted rotatably in the hinge pot and
may be used to press the locking part away from the
nose.
An example embodiment of the invention is described
below with reference to the figures of the attached
drawings.

section to that of Fig. 11, with the coupling part

5 ~03~613
show two parts of a two-part coupling part,
respectively in plan view, in side view and in section.
The hinge pot 1 shown in Fig. 2 comprises a flat
cylinder 2 provided on the outside with ribs 3 and cut
away in a segment shape on one side so that it has a
flat side 4 ending at the end face of the furniture
unit door 26.
The hinge pot 1 is provided with a flange 5 which bears
against the furniture unit door 26.
The hinge pot 1 has a recess 6 into which the coupling
part 7 may be inserted and in which it may be anchored.
On the two side walls 8 of the recess 6 are shoulders 9
which project into corresponding recesses 10 of the
coupling part 7. In the example embodiment, the
shoulders 9 and the recesses 10 have a straight side
wall 11 and a curved side wall 12, the side walls 11,
12 diverging towards the base of the hinge pot 1.
The locking part 13 is mounted tiltably on an axis 14
at the front end of the coupling part 7. If the
coupling part 7 is inserted in the recess 6 of the
hinge pot 1 in such a way that the recesses 10 receive
the shoulders g snugly, the locking part 13, which is
- 6 ~037613
acted upon by a spring 22, latches behind the nose 15
of the hinge part 1 and thus locks the coupling part 7
in the hinge pot 1.
In order to improve the retention of the coupling part
7 in the hinge pot 1, corresponding stops 16, 17 may be
provided, which prevent the coupling part 7 from being
pressed away at the side facing the hinge arm 20. The
stops 16 are on the flattened-off side 4 of the hinge
pot 1, and the stops 17 are on the corresponding flat
side of the coupling part 7.
Mounted in the hinge pot 1 is a further unlocking lever
18 which ends flush with the flange 5 and whose
function will be explained later.
In order to enable the hinge to be adjusted depthwise,
the coupling part 7 may be of two-part construction,
namely comprising a part 7' which is mounted on the
hinge axis l9 and a part 7" in which the recesses 10
are made and on which the axis 14 or the mounting eye
forming the axis 14, for the locking part 13, is
constructed.
The parts 7', 7" are held together in clamping manner
by a screw 21. To do this, the screw 21 projects
through an elongate hole 28 in the part 7'. The length
Z~37613
of the elongate hole 28 determines the extent of
depthwise adjustment.
The leaf spring 22, which presses the locking part 13
against the side wall of the recess 6 and against the
nose 15 of the hinge pot 1, is held in clamping manner
between the parts 7', 7", as can be seen from Figs. 10-
12.
As can be seen from Fig. 11, a leg 22' of the leaf
spring 22 presses against the base of the hinge pot 1
and is received in a recess 23.
The hinge arm 20 is shown in Fig. 5. It has a leg 20'
which bears laterally against the furniture unit wall
27, a leg 20" and mounting devices 24 for the hinge
axis 25.
On mounting the hinge, the hinge pot 1 is on the one
hand set in the door leaf 26 and the hinge arm 20 is
secured to the furniture unit side wall 27, for example
screwed thereto. Mounted on the hinge arm 20 by means
of the hinge axis 25 is the coupling part 2 with the
locking part 13, the two parts (7',7") of the clamping
part 7 being held together by means of the clamping
screw 21.

In order to mount the door leaf 26 on the furniture
carcass, all that needs to be done is to bring the door
leaf 26 with the hinge pot 1 up to the coupling part 7
such that the shoulders 9 may be pushed into the
recesses 10. This is possible in any position of the
coupling part 7, i.e. at virtually any angle of opening
of the door 26.
The coupling part 7 is locked in the hinge pot 1
automatically, since the locking part 13 (as mentioned
earlier) is pressed below the nose 15 by the spring 14.
If the door leaf 26 is to be released from the
furniture carcass, i.e. the hinge pot 1 is to be
separated from the coupling part 7, all that needs to
be done is to pivot the unlocking part 18 away from the
flange 5 as shown in Fig. ~7, as a result of which the
,~,
locking part 13 is pressed away from the nose 15. At
the same time, the leg 22' of the leg spring 22 presses
the hinge pot 1 away from the coupling part 7, so that
the hinge pot 1 is reliably prevented from getting
stuck.
After the unlocking part 18 has been brought back into
its initial position, i.e. parallel to the flange 5,
the hinge arm be coupled at any time.
