Device for Receiving a Di-awer
The invention relates to a means for the releasable receptacle of a drawer
which is laterally provided with
two telescopic drawer buides in a body of a piece of furnitlu-e with each of
the two telescopic guides
coinprising a rail.
Drawers with telescopic drawer bruides must be accoiiin7odated in the
designiated drawer opening of the
body of a piece of furniture in a nlaiuier that ensures that, on the one hand,
inadvertent complete pulling
out of the drawer is prevented, and, on the other hand, it is possible to
release the drawer so that it can be
fully removed if this is desired, for example for cleaning purposes.
In known devices of drawers as described in the introduction the telescopic
drawer guides are attached to,
for example screwed to, the two lateral inside walls of the drawer opening of
the body of the piece of
furniture. The drawer is fastened to its respective guide rails and can be
released. To accomplish this, the
guide rail engages into a rear recess of the drawer at the rear end. At the
same time the guide rail is
fastened to a coupling device at the bottom of the drawer so that it can be
released. To this end it is
necessary to provide a means at the back edge of the drawer to provide the
areas or recesses necessary so
that the guide rail can engage. In addition, the design efforts for such
coupling devices are relatively
extensive, and the height of this coupling device reduces the useable space of
the drawer.
The object of the invention therefore is to provide a device for receiving a
drawer as defined in the
introduction that allows for the removal of the drawer from the body of the
piece of furniture without
much design effort.
The object is attained in that the rail, on the reai- end thereof, can be
pushed onto a rear receiving fitting
on the body of the piece of fui-niture in the guiding direction, and on the fi-
ont end thereof, can be engaged
with a fi-ont receiving fitting on the body of the piece of fiurniture, that a
lateral snap-in pin proj ects from
the rail close to the fi-ont end thei-eof, said snap-in pin being inscrfable,
ii1 the guiding dii-ection, into a
snap-in slit which is open towards the front and located on the front
receiving fitting. A spring-loaded
locking rockei- secui-es the snap-in pin in the position thei-eof in the snap-
in slit. The locking rocker can be
displaced into a release position for releasing the snap-in tongue by
actuating a release gear.
No additional woi-k on the drawer is neeessary to allow for the connection to
the telescoping drawer

guides. Inserting the drawer can be accomplished easily by inserting the
drawer from the front until the
rear end of the rail is in the rear receiving fitting and the front end
engages with the front receiving fittint,
The locking rocker pi-events an inadvertent pulling out of the telescopic
drawer guides from the receiving
fittings of the body of the piece of furniture. If the dT-awer is to be
removed, the locking rocl:er can be
displaced into a release position by actuating a release gear in which the
locking means releases so that it
can be pulled to the front and out of the snap-in slit. At the same time the 1-
ear end of the 1-ail i-eleases froin
the rear receiving fitting without requiring the release of any coupling
devices or such. Since the
coimection of the rail at the rear end as well as at the front end is
accomplished by a simple pushing
motion, a slanted area can be used at the rear end in a simple marmei- to
ensure that the telescopic drawer
guides are lifted into the operating position at the end of the pushing pi-
ocess.
The locking means can be a snap-in tongue or a snap-in pin.
In a furtller development of the inventive thought the locking rocker pivots
between its locking position
and its release position by overconiing the force of a rocker spring. The
locking rocker thus is a bi-stable
means that is maintained in a spring position in its locking as well as in its
release position until it is
pivoted back into the respective other position. To this end it is practical
if the locking rocker can be
displaced from its locking position by the snap-in tongue until the snap-in
tongue can be inserted into the
snap-in slit and that the locking rocker then returns to its locking position.
The locking rocker in the
locking position therefore is overcome in a resilient mamier due to the snap-
in tongue when the drawer is
inserted and then retui-ns to the locking position to secure the snap-in
tongue.
Accoi-ding to a preferred embodiment of the invention a rocker ann of the
locking rocker in the release
position extends into the path of motion of the snap-in tongue and displaces
the locking rocker due to the
engagemelt of the snap-in tongue on the rocker arm in its locking position.
This nleans that the locking
i-ocker that is displaced into the release position for removing the drawer is
displaced back into the
locking position by the snap-in tongue when the drawer is pulled out so that
the locking rocker is in the
locking position when the drawer is inserted again. This ensures that one does
not forget to retuni the
locking rocker back into the locking position after the drawer is inserted
again and that thei-e is no
possibility of inadvertently removing the drawer completely.
Other advantageous embodiments of the inventive thougllt al-e the subject of
additional dependent claiins.

release of the locking rocker; and
Fig. 14 shows a bottom view according to Fig. 13 of the device in the position
in which the outer rail of
the telescopic drawer guides is partially pulled out.
The device shown in Fig. 1- 9 is used to provide a releasable i-eceptacle of a
drawer I in the body of a
furniture piece 2(Fig. 4). A rear receiving fitting 4 and a fi-ont receiving
fitting 5 ai-e arranged on the two
opposite lateral inside walls 3 of the body of the furnitui-e piece. The terms
"front" and "rear" refer to the
3
CA 02597990 2007-08-15
opening in the body of the furniture piece that acconunodates the drawer 1.
The two receiving fittings 4 and 5 are screwed to the respective inside wall 3
and are connected by a
spacer rail 6.
The drawer I comprises a telescopic drawel- guide 7 on each side with each
having ai-ail S. Arranged at
the rear end of each i-ail 8 is a lioi-izontal i-eceiving slit 9 that expands
towards the rear and that can be
pushed from the fi-ont aci-oss a hoi-izontal ton~a.ie 10 of the rear receiving
fitting 4 protruding to the inside
when the drawer is pushed into the body of the piece of furniture from the
front. The upper edge of the
receiving slit 9 transitions nito an inclining stop edge (9a) towards the
rear.
A lateral, llorizontal snap-in tongue 11 protrudes near the front end of each
rail 8. A snap-in slit 12, which
is open towards the front, is located on the front receiving fitting 5, into
which the snap-in tongue 11 can
be inserted from the fi-ont in the guiding direction, wlule the receiving slit
9 simultaneously is pushed
over the tongue 10.
Based on the position shown in Fig. 1, the lateral rail 8 together with the
drawer reaches the end position
shown in Fig. 2. When the drawer is inserted, the outside rail I a of the
telescopic drawer guide that is
cormected to the drawer glides on a horizontal guide leg 6a of the spacer
rai16 until the inclining stop
edge 9a of the receiving slit 9 engages with the tongue 10. Due to the incline
of the stop edge 9a, the
outside rail 8 and at the same time the wider drawer guide la that is attached
to the drawer 1 is lifted. The
drawer guide 1 a that is indicated with a dash-dotted line in Fig. 1 thus
reaches the indicated position
above the spacer rail 6. This ensures that the mobile drawer guide 1 a moves
freely and without friction
across the leg 6a of the spacer rail 6.
A two-armed locking rocker 13 is arranged in a pivoting matuzer on the fi=ont
receiving fitting 5 around an
axle 14 that extends latei-ally to the guiding dii-ection. A release gear 5 is
airanged in a pivoting nZanner
around an axle 16 that extends laterally to the guiding direction. The release
gear 15 has a touch ai-ea 17
that is accessible from the front.
In the embodiment according to Fig. 1- 6, a leg spring 18 arranged on the axis
16 on the front receiving
fitting 5 provides a rocker spring for the locking rocker 13 comprised of its
first spring leg 19. With its
second spring leg 20, the leg spring 18 pushes onto the back side of the touch
area 17 to keep the r-elease
-ear 15 in counterclockwise du-ection in Fig. I in its resting position shown
in the Figure.
4
CA 02597990 2007-08-15
On the side that faces the spring leg 19, the locking rocker 13 has two stop
faces 21 and 22 that are at an
angle in relation to each other. The first spring leg 19 i-ests in the locking
position of the locking rocker 13
on the stop face 22 as shown in Fig. 1. In the position of the locldng i-ockei-
13 shown in Fig. 2, the fi-st
spring leg 19 rests against the othei- stop face 21.
As is shown in Fig. 1, a rockel- arm 23 of the locking i-ockei- 13 in locking
position (Fig. 1) eatends into
the path of rnotion of the snap-in tongue 1 l. When the snap-in tongue 11 is
moved froln the position
shown in Fig. I backward into the snap-in slit 12, the locking i-ocker 13 is
deflected fi-oin its locking
position by the snap-in tongue 1 1 until the snap-in tongue 1 l can be
inserLed into the snap-in slit 12. The
locking rocker 13 subsequently retums into its locking position due to the
effect of the rocker spring
comprised of the spring ann 19 and retains the snap-in tongue I 1 in the snap-
in slit 12.
The locking rocker is comprised of a two-armed lever and has another rocker
ann 24. In order to release
the drawer from its locked position, one pushes on the touch area 17 from the
front. The release gear 15
that is retained in its resting position by the spring force pushes against
the stop face 22 of the locking
rocker 13 with an actuation nose 25 when actuated and in this manner displaces
the locking rocker 13 into
its release position (Fig. 3) against the force of the spring leg 19.
In this release position that is shown in Fig. 2 and Fig. 3, the second rocker
arn124 of the locking rocker
13 in release position extends into the path of motion of the snap-in tongue
11. If the drawer, which now
is released, is pulled out towards the front, the snap-in tongue 11 displaces
the locking rocker 13 into the
locking position shown in Fig. 1 by engaging with the rocker ann 24. Thus the
locking ai7n 13 can be
displaced between its locking position (Fig. 1) and its i-elease position
(Fig. 2) while ovei-coming the force
of the rocker spring 19.
As soon as the snap-in tongue 11 overcomes the locking spi-ing in the
described inannei-, the drawer can
be removed coinpletely and it is no longer necessary to push down the release
gear 15. As soon as the
drawer is inserted again, the snap-in tonbrue 1 I that i-ides on the upper
side of the rocker arin 23 pivots the
rockei- ai7n 23 down until it allows the snap-in tongue I 1 to pass. However,
this does not yet put the
locking rockei- 13 into its i-elease position as a second stable position, but
rather it returns to the locking
position as soon as the snap-in tongue I 1 has passed the i-ocker arnl 23.
The embodiment shown in Fig. 7 - 9 is different from the embodiment described
above substantially only
CA 02597990 2007-08-15
in that the release gear 15 arranged on the fi-ont receiving fitting 5 is not
spring loaded. The locking rocker
13 is retained in its locldng position (Fig. 7) as well as its release
position (Fig. 9) by a rocker spring 27
that rests against an abutment 26 on the fi-ont receiving fitting 5. In the
locking positions (Fig. 7), the
point of impact 27a of the i-ocker spring 27 is on the locking rocker I 3
above the comlecting line between
the abutment 26 and the axis 14 of the locking rocker 13. This locking
position thus is a iii-st stable
position of the locking rocker 13.
After the locking rocker is displaced in a counterclockwise dii-ection against
the force of the rocker spring
27 frorn this locking position by ineans of actuating the release gear 15 from
this locking position (Fig. 8),
the point of impact 27a of the rocker spring 27 reaches a position below the
coiu7ecting line between the
abutment 26 and the axis 14. At the sanle time the locking rocker 13 rests
against an abutment 28 on the
front receiving fitting 5. The locldng rocker 13 now is in a second stable
position. In this release position
(Fig. 9) that con-esponds to the position shown in Fig. 2, the snap-in tongue
11 can be moved out from the
snap-in slit 12 as already described and displaces the locking i-ocker 13 back
into the starting position
according to Fig. 7 when it passes the rocker ann 24.
The modified exenzplary embodiment shown in Fig. 10 - 14 is different from the
described einbodiment
in that the snap-in means is not a laterally protruding snap-in tongue but
rather a snap-in pin 29 that
protrudes downward into the snap-in slit 12 that is arranged in a horizontal
plate 30 of the rail 8. The
loclcing rocker 13' is an-anged in a pivoting mam7er around a vertical axis
comprised of a vertical pin 31
on the plate 30 and can be pivoted from its snap-in position (Fig. 12) into
its release position (13) against
the force of a leg spring 18'. The locking rocker 13' has a locking arm 32 on
which a stop hook 33 is
arranged that extends behind the snap-in pin 29 in the snap-in position and
retains and secures it in the
snap-in position (Fig. 12).
In this position the rear end of the rail 8 is fastened to a receiving hook 34
that is bent at a right angle
fi-om the i-ear receiving fitting 4.
The locking rockei- 13' has an actuating ann 35 that is arranged at a distance
to the locking ann 32, on
which a touch ai-ea 17' is arranged, around which the locking rocker 13'
pivots against the force of the leg
spring I 8' fi-oin its locking position shown in Fig. 12 into its i-elease
position shown in Fig. 13. Afler the
stop liook 33 releases the snap-in pin 29, the rail 8 can be pulled out with
tlie now released snap-in pin 29
moving along the snap-in slit 12.

CA 02597990 2007-08-15
The actuation ann 35 of the locking rocker 13' that now is inoved into the
release position shown in Fig.
13 in order to release the snap-in pin 29 can be fixed in this release
position.
To this end, the actuation arm 35 comprises a final section 36 on which a
spring tongue 37 is arranged
that is bent laterally in relation to the plate 30. In the release position
(Fig. 13) of the locking rocker 13',
the tongue 37 snaps into the snap-in slit 12 and i-etains the locking rocker
13' in the position that is
shown.
From the extension 36 a tab 38 protrudes to the rear, i.e. towards the inside
end of the snap-in slit 12 that
is angled diagonally away from the plate 30 and thus forms a diagonal area
against which the snap-in pin
29 runs during its forward motion (towards the right in Fig. 13). During its
motion along the snap-in slit
12, the snap-in pin 29 that is released from its snap-in position engages with
the diagonal area of the
actuation ann 35 to release the actuating ann 35 from its fixed position
diagonal to its pivot plane. The
tongue 371eaves the snap-in slit 12 and the locking rocker 13' returns from
its position shown in Fig. 13
into the position shown in Fig. 14 due to the spring effect of the leg spring
18'. The actuating ann 35 of
the locking rocker 13' thus can be fixed in the release position (Fig. 13) and
can be released from this
fixed position when the snap-in pin 29 moves past.
The stop hook 33 of the locking ann 32 has a front diagonal area 39 against
which the snap-in pin 29 runs
when it is inserted to the left into the snap-in slit 12 from the released
position shown in Fig. 14. When
the snap-in pin 29 is inserted, the stop hook 33 can be displaced against the
spring force of the leg spring
18' from the path of motion of the snap-in pin 29 and is retained by it in the
snap-in position when the
stop hook 33 returns into its retaining position aecording to Fig. 14.
To remove the drawer from the body of the funliture piece, the locking rockers
13' are displaced by
puslling on the touch areas 17' on both latei-ally provided telescopic drawer
guides so that the two snap-in
pins 29 ai-e released. The two i-ails 8 now can be removed together with the
d1-awer.
It is undei-stood that the device described above can be used in any kind of
drawer guides that have a
corresponding rail 8 on the outside. The details of the telescopic drawer
guides al-e not of iinportance and
tl-ierefore are not included in the drawings. Usually these are ball bearing
oi- i-oller beai-ing guides.
