GUIDE POUR TIROIRS

English Abstract

A B S T R A C T
A pull-out guide for drawers, having a carcass-side bearing rail
(3) and a drawer-side pull-out rail (6) at each side of the
drawer. Load-transmitting rollers (4, 16, 17) are mounted on the
rails (3, 6). The rails (3, 6) have running webs for the rollers
(4, 16, 17) and the rollers (4, 16, 17) of the bearing rails (3)
and of the pull-out rails (6) are offset perpendicular with
respect to the pull-out direction of the pull-out rails (6) such
that the pull-out rails (6) are guided in two tracks. There are
mounted on the pull-out rails (6) two rollers (16, 17) which are
arranged one above the other and which receive between them the
running web (18) of the bearing rail (3). Next to the upper
roller (16), a support block (12) of plastics is arranged in the
track of the roller (4) mounted on the bearing rail (3).

Description

Description
The invention relates to a pull-out guide for drawers, having a
carcass-side bearing rail and a drawer-side pull-out rail at each
side of the drawer, load-transmitting rollers being mounted on
the rails and the rails having running webs for the rollers and
the rollers of the bearing rails and of the pull-out rails being
offset perpendicular with respect to the pull-out direction of
the pull-out rails such that the pull-out rails are guided in two
tracks.
A pull-out guide of this type is described in DE-A1 36 27 408.
It is not suitable for receiving drawers having heavy contents.
The object of the invention is to improve a pull-out guide of
this type such that a good tip-safe guidance of the pull-ou~
rails on the bearing rails is ensured and that the bearing rails
can be constructed to have only one running web.
The object according to the invention is achieved in that there
are mounted on the pull-out rails two rollers which are arranged
one above the other and which receive between them the running
web of the bearing rail, in that in parts the bearing rail has
an inverted L-shaped profile, and in that the bearing rail-side
roller i8 mounted on the side of the vertical web of the bearing
rail opposite the running web.
A preferred embodiment of the inventio~, in which the suspension
of a drawer removed completely from the furniture carcass is
facilitated, provides for a support block, preferably of
plastics, to be arranged at the rear ends of the pull-out rail
next to the upper roller in the track of the roller mounted on
the bearing rail.
An embodiment of the invention will be described in detail below.
Fig. 1 shows, in schematic and exploded manner, a pull-out guide

~ J ~ 3 ~
according to ~he invention having a drawer frame and the drawer
rear wall; Fig. 2 shows a section through a pull-out rail
according to the invention, in the rear region; Fig. 3 shows a
diagram of the pull-out rail according to the invention, in the
rear region; Fig. 4 shows a similar diagram to Fig. 3, with
removed run-on block, and ~ig. 5 shows an end view of the pull-
out guide inserted into the drawer frame.
The pull-out guide according to the invention has on each side
of the drawer a bearing rail 3 secured to the furniture carcass
side walls and a pull-out rail 6 connec~ed to the drawer frame
1. The bearing rail 3 has a running web 18 and is provided at
the side of a vertical web 19 opposite the running web 18 with
a roller 4 which i8 mounted on the vertical web 19 by means of
a rivet 5.
The bearing rail 3 is screwed in conventional manner to the
furniture side wall or frame parts of a furniture carcass by way
of a securing web 20. The bearing rail 3 here describes an
assembled Z- and U-shaped profile (Fig. 5~.
The pull-out rail 6 bears at the front end a holding plate 7 on
which a front fitting 8 for securing a front panel can be
screwed. In the drawer frame 1, located in the outer wall 1' in
the region of the front fi~ting 8, is a cutout which enables the
access of a tool to the front fitting 8 and which is covered by
a cover cap 2.
The pull-out rail 6 is further provided with a supporting web 21
for the drawer base and a running web 22 for the bearing rail-
side roller 4.
At the rear end of the pull-out rail 6 an adapter 13 is secured,
for example screwed or riveted, to the pull-out rail 6. The
adapter 13 bears two rollers 16, 17 which are arranged one above
the other and which are mounted on the adapter 13 and thus on the
pull-out rail 6 by means of rivets 14 which project through holes

15 in the adapter 13.
When the drawer is pushed into the furniture carcass, the rollers
16, 17, as can be seén in particular from Fig. 5, àre ~ocated
above and below the running web 18 of the bearing rail 3. The
pull-out rails 6 and the drawer are thus guided in tip-safe
manner on the bearing rails 3.
The adapter 13 has an upper horizontal web 23. Inserted between
the upper horizontal web 23 of the adapter 13 and the running web
22 of the pull-out rail 6 is a support block 12 which projects
rearwards beyond the running web 22 of the pull-out rail 6 and
has a run-on surface 24 which extends the running web 22 beyond
the rollers 16, 17.
The support block 12 has a lug 25 which projects into a hole 26,
for example a punched hole in the horizontal web 23 of the
adapter 13, and holds the support block 12 which is inserted
between the adapter 13 and the horizontal web 22 of the pull-out
rail 6.
The assembly of the rollers 16, 17 on producing the pull-out
guide is facilitated by the fact that the running web 22 of the
pull-out rail 6 terminates hefore the rollers 16, 17. The
support block 12 can easily be inserted between the adapter 13
-and the pull-out rail 6 after the rollers 16, 17 have been
assembled. It facilitates the suspension of the drawer removed
from the furniture carcass and improves the take-up of force by
the pull-out rail 6.
In order to improve the guidance of the bearing rail-side roller
4 in the region of the run-on block 12, the latter is provided
with lateral guide cheeks 27. The guide cheeks 27 e~actly match
the oblique side webs of the downwardly open profile of the
running web $8. The running web 22 of the pull-out rail 6 also
has a downwardly open profile in which the roller 4 is guided.

Also mounted on the adapter 13 is a rear wall holding means 11
for the rear wall 10.
Mounted in the vertical web of the pull-out rail 6 is a block 9,-
preferably of.plastics, which improves the lateral guidance of
the pull-out rail 6. - - -
