FIEED AND 8ACKGROUND OF THE INVENTION
The invention relates to a fitting for fastening the rail
member of a drawer to a front plate or rear wall of a
drawer, said rail member being provided with a hook member.
In modern furniture construction, drawers are widely known
in which the front plate is adjustably fastened to the
drawer side walls, i.e. to the side walls of the piece
of furniture, by means of clip-in fittings. In some
cases, a rail member is provided at the drawer above each
drawer side wall and extends from the front plate to the
rear wall of the piece of furniture or to a support member
at the rear wall of the piece of furniture.
The same Applicant suggests in a prior application to use
said ra;l member for the adjustment of the front plates.
In this arrangement, the rail member is provided with
a threaded pin which is screwable into a holding member
which is fittable into the front plate.
Furthermore, furniture connectors with dowel-like casings
are generally known which allow a clamping connection
between parts of pieces of furniture~
SUMMARY OF THE INVENTION
It is the object of the invention to provide a connecting
fitting which allows quick engagement of a rail member in
3~

3~14
the front plate or rear wall of a drawer.
According to the invention this is achieved by a dowel
casing which is fittable into the front plate or the like
and into which a hook member is engageable by means of the
hook, said hook member being connected with the rail
member or moulded thereto and projecting through an
opening into the dowel casing.
The dowel casing according to the invention can be
mounted in an easy and quick manner without the necessity
of screws. A particular alignment need not be taken into
consideration. Moreover, the complete fitting is received
in the front plate.
It is advantageously provided that a metallic disk is
inserted into the dowel casing which is made of plastics
material, said disk having an opening through which the
hook member extends with its head.
~y means of the metallic disk, the forces exerted by the
hook can be taken up by a larger area of the dowel casing.
An embodiment of the invention provides that the hook
member is provided with a flange which abuts flush with
the dowel casing in the mounted position and is bevelled
at the side opposite the hook.
Due to this arrangement, the rail member and the hook
member are snuggly held at the dowel casing in the engaged

3C~4
position, the hook member having cylindrical shoulder which is
snuggly received in the opening of the dowel casing, with
engagement and disengagement of the hook member being easy
nevertheless.
In the following an embodiment of the invention will be
described in more detail with reference to the figures of the
drawing in which
Figure 1 shows a diagrammatic view of a drawer
according to the invention,
lo Figure 2 shows a vertical sectional view of a fitting
according to the invention, with the rail member being engaged,

according to the invention, the hook member being shown in an
intermediate position when being engaged and disengaged,
respectively,

of the drawer.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The fitting according to the invention comprises a dowel
casing 5 which is fittable into the front plate 1 and
a hook member 6 which screwed into the rail member 4.
The hook member 6 is advantageously made of diecasting,
but it can equally be of plastics material.
The dowel casing 5 is ;njection moulded plastics material.
The dowel casing 5 has a hollow space 8 and a central
opening 9. A metallic disk 7 is fitted into the hollow
space 8. The metallic disk 7 is held in an undercut 10
by means of a projection or projections 11.
The hook member 6 has a head 12 with a hook 13.
To permit insertion of the head 12 into the opening 9, the
head 12 has a bevelled portion 18. The rail member 4 is
fastened by pushing the dowel casing 5 into the front
plate 1 in a manner known per se and by then scrr-wing or
inserting the hook member 6 into the rail member 4. Then
the rail member 4 is by means of the hook member 6

3~i~
engageable in the dowel casing 5 through the opening 9
in the manner shown in Fig. 3, so that the hook 13
comes to lie behind the metallic disk 7, as shown in
Fig. 2.
The hook member 6 has a flange 14 which abuts flush with
the dowel casing 5, i.e. at the front side thereof. The
flange 14 is provided with a bevelled portion 15 opposite
the hook 13 to avoid that the flange impedes engaging
and disengaging of the hook member 6.
The avoid wobbling of the rail member 4, the hook member
is provided with a cylindrical shoulder 16 which is
snuggly received in the opening 9 of the dowel casing 5.
The dowel casing 5 has in a manner known per se
circumferential r;bs 17 wh;ch ensure ;mproved anchoring
of the dowel casing 5 in the front plate 1.
