Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application claims the benefit of priority to
German Patent Application No. 20 2009 011 106.7, filed Oct. 2,
2009, the contents of which is incorporated herein by reference in
its entirety.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to a locking configuration, or
locking arrangement, of an adapter or a thrust element, or drawer,
having a pullout guide, which is fastened on a furniture body of a
piece of furniture or in a household appliance, according to the
preamble of Claim 1 and a piece of furniture or a household
appliance.
[0003] Various locking configurations, or locking arrangements, of
an adapter having a pullout guide which is fastened on a furniture
body of a piece of furniture are known from the prior art. To lock
the adapter, the adapter is provided with two tongues or hooks, for
example, which are pluggable into tabs provided laterally on a
slide rail of a pullout guide and are subsequently held in this
position using screws.
[0004] Such a locking configuration, or locking arrangement, has
the disadvantage that many work steps are required for installing
the adapter on the slide rail, for which various tools must be
used.
[0005] The object of the present invention is to provide a locking
configuration, or locking arrangement, of an adapter or a thrust
element, or drawer, having a pullout guide, which is fastened on a
furniture body of a piece of furniture or in a household appliance,
which allows a simplified installation of the locking of the
adapter or the thrust element, or drawer, with the pullout
guide.
[0006] This object is achieved by a locking configuration, or
locking arrangement, having the features of Claim 1.
[0007] According to the invention, the receptacle opening into
which the hook is insertable is shaped so that the hook is
insertable transversely to the movement direction of the slide rail
and is subsequently displaceable in the movement direction of the
slide rail. Through the insertion of the hook into the slot of the
receptacle opening, a lift-out safety is achieved for the adapter
or the thrust element, or drawer, in the transverse direction to
the pullout direction. Furthermore, at least one recess is provided
on the adapter, the thrust element, or drawer, or the slide rail,
and a detent lug which is lockable in the recess is provided on the
slide rail, the thrust element, or drawer, or the adapter, the
recess being positioned so that the detent lug is first lockable in
the recess wherein the hook is displaced in the movement direction
of the slide rail. On the one hand, tool-free installation of the
adapter on the pullout guide is made possible using such a locking
configuration, or locking arrangement, according to the invention.
The locking of the adapter with the slide rail by the detent lug
additionally ensures secure locking, which cannot be detached by
the end-user, of the adapter or the thrust element, or drawer, with
the slide rail. Furthermore, through the fixing with the aid of the
detent lug, fewer components are also required for installing the
adapter or the thrust element, or drawer, on the pullout guide and
therefore also fewer work steps.
[0008] Advantageous embodiments of the invention are the subject
matter of subclaims.
[0009] According to an advantageous embodiment variant of the
locking configuration, or locking arrangement, the adapter is
implemented as an L-shaped bent part which is bent over in the
longitudinal direction, a first leg of the adapter being lockable
on the slide rail and detent means being provided on a second leg
for locking a front panel. Tool-free installation of the front
panel on the adapter is thus also made possible. The installation
of the front panel on the adapter can be performed before or after
the installation of the adapter on the pullout guide.
[0010] According to a further embodiment variant, a holding web for
holding a container is shaped on the adapter along a lower
longitudinal edge. Using such a holding web, a container can be
held removably between two pullout guides which are situated
parallel to one another, for example, on the side walls of the
furniture body.
[0011] In an advantageous embodiment variant, the receptacle
openings are shaped so that the hooks are fixable in receptacle
openings perpendicularly to the sliding direction of the slide
rail. Through the fixing of the adapter using the detent lug in the
sliding direction of the slide rail, fixing of the hooks in the
receptacle openings perpendicularly to the sliding direction of the
slide rail is also ensured by the receptacle openings shaped in
this manner.
[0012] The thrust element, or drawer, is preferably manufactured
from sheet metal.
[0013] Other aspects of the present disclosure will become apparent
from the following descriptions when considered in conjunction with
the accompanying drawings.

DETAILED DESCRIPTION
[0018] In FIGS. 1 and 2, reference numeral 1 refers to a piece of
furniture having a furniture body 2, in which two pullout guides 4
are fastened, on which a movable furniture part, for example, in
the form of a drawer or a container 8 and a front panel 3, is
situated. The piece of furniture 1 can be implemented as living
room furniture, office furniture, kitchen furniture, or also as a
household appliance, in particular as a refrigerator or freezer.
The pullout guide 4 preferably comprises a guide rail 5, which is
fastened on an inner side of the furniture body 2, and a slide rail
7, which is movable in the guide rail 5. At least one
pullout-lengthening middle rail 6 can be situated between the guide
rail 5 and the slide rail 7. The pullout guide 4 is preferably
implemented as a roller body pullout.
[0019] An embodiment variant of the slide rail 7, which is situated
on the adapter 9, is shown in detail in FIG. 5. The slide rail 7
essentially comprises a flat plate 23 having bent-over longitudinal
side edges, whose outer sides are enclosed by the inner sides of
bent-over edges of the middle rail 6 and between which a ball
bearing (not shown) is received. Hooks 18 are shaped onto the flat
plate 23, which are shaped so that they initially protrude from the
flat plate 23 by approximately one adapter plate thickness from the
side of the flat plate 23 facing away from the guide rail and are
then bent over parallel to the flat plate 23. An end section 19 of
the hook 18 is bent over away from the flat plate 23 from the part
of the hook 18 running parallel to the flat plate 23. To couple the
slide rail 7 to the middle rail 6 or the guide rail 5, a detent
hook 21 is raised from the side of the flat plate 23 facing toward
the guide rail 5.
[0020] Furthermore, a detent lug 20 protrudes from the side of the
flat plate 23 facing away from the guide rail. The hook 18 and the
detent lug 20 are used for fixing the adapter 9, which is shown in
various perspectives in FIGS. 3 and 4. This adapter 9 is
implemented in the embodiment variant shown here as an L-shaped
bent part which is bent over in the longitudinal direction, a first
leg 10 of the adapter 9 being lockable on the slide rail 7 and
detent means 17 being provided on the second leg 11 for locking
with the front panel 3, which is shown in FIGS. 1 and 2.
[0021] Receptacle openings 13 are implemented on the adapter 9 to
receive the hooks 18, which are situated at the same distance to
one another as to hooks 18 on the slide rail 7. The implementation
of only one hook 18 on the slide rail 7 and one receptacle opening
13 on the adapter 9 is also fundamentally conceivable. It is also
conceivable that the hooks 18 are implemented on the adapter 9 or
the thrust element, or drawer, and the receptacle openings 13 are
implemented on the slide rail 7.
[0022] The receptacle openings 13 are shaped so that the hook 18 is
insertable transversely to the movement direction X of the slide
rail 7 and is subsequently displaceable in the movement direction X
of the slide rail 7.
[0023] Furthermore, at least one recess 15 is provided on the
adapter 9, in which the detent lug 20 on the slide rail 7 can
engage during the installation of the adapter 9 on the slide rail
7. The distance of the recess 15 from one of the receptacle
openings 13 is dimensioned so that the detent lug 20 can first be
engaged in the recess 15 during the displacement of the hook 18 in
the movement direction X of the slide rail 7. In order to allow
this, the receptacle opening 13 is preferably implemented as a
rectangular recess, in which a slot 14, which extends in the upper
edge area in the movement direction X of the slide rail 7, opens.
Thus, as shown in FIGS. 6a to c, the adapter 9 can first be pushed
from above onto the hook 18 of the slide rail 7 (FIGS. 6a and 6b)
and subsequently, by pulling on the adapter 9 in the pullout
direction or by pulling on the front panel 3, which is already
connected to the adapter 9, the hook 18 can be inserted into the
slot 14, as shown in FIG. 6c. As is also shown in FIGS. 6b and 6c,
the detent lug 20 is first locked in the recess 15 in the position
shown in FIG. 6c, i.e., when the hook 18 is inserted into the slot
14 of the receptacle opening 13.
[0024] The front panel 3 can be locked with the adapter 9 via
detent means 17, which are shaped on the second leg 11 of the
adapter 9. Optionally, one or more holes 16 for receiving a screw,
a dowel, or the like can be implemented on the second leg 11, in
order to additionally fix the front panel 3 on the adapter 9 by
screw connections, for example.
[0025] The embodiment variant of the adapter 9 shown in FIGS. 3 and
4 further has a holding web 12 for holding a container 8, for
example, along a lower longitudinal edge. To fix this container 8
on the end of the adapter 9 diametrically opposite to the front
panel 3, the adapter 9 is preferably also implemented having a
holding surface 22 there, so that the container 8 is securely
fixable by the holding surface 22 and the holding web 12.
[0026] The receptacle openings 13 shown here may also be
implemented as pockets in a further embodiment variant (not shown).
It is important that in the design of the above-described locking
configuration, or locking arrangement, tool-free installation of
the adapter 9 on the slide rail 7 is made possible and because of
the design of the hooks 18, the receptacle openings 13, and the
positioning of the detent lug 20 and the recess 15 which receives
the detent lug 20, secure fixing of the adapter 9 on the slide rail
7 is ensured, which can only be disengaged again by an end user
with great application of force and the risk of destroying the
locking configuration, or locking arrangement.
[0027] Although the present disclosure has been described and
illustrated in detail, it is to be clearly understood that this is
done by way of illustration and example only and is not to be taken
by way of limitation. The scope of the present disclosure is to be
limited only by the terms of the appended claims.
