[0001] The present invention relates to an interior fitting, such as a cabinet door,.shelf
end-piece, door or the like with interchangeable insert or filler, said insert comprising
a closed frame in the form of jointed opposing pairs of frame members, defining a
central opening, each of said frame members being provided on its interior edge surface
facing said opening with a longitudinal groove for housing a peripheral tongue portion
of the essentially board-shaped insert, said insert having at least one raised portion,
the thickness of which is greater than the width of the grooves in the frame members,
the groove in one of the frame members being so deep that it opens onto the opposite
outer edge surface of this frame member.
[0002] The primary purpose of the present invention is to achieve an interior fitting, such
as a cabinet door, door, shelf end-piece or the like, which makes it possible, without
nails, glue, putty or even tools, to interchangeably after- insert such an insert
in the central opening of the already fully assembled frame. The insert in question
has raised portions which are thicker than the assembly grooves for the insert on
the interior edges of the frame members, i.e. an insert, the width and height of which
are greater than the width and height of the central opening defined by the individual
frame members.
[0003] To achieve this the interior fitting mentioned in the introduction is characterized
in that for after-insertion or removal of the insert into or from the finished frame,
the insert is divided into a plurality of sections along at least one dividing line
which is oriented essentially transversally to the longitudinal axis of the frame
member containing the groove opening into said outer edge surface, at least one of
said sections containing the raises portion of the insert, while at least one other
section of the same forms an essentially flat member which can be inserted through
the groove which opens into said outer edge surface. Such a design of the insert makes
it possible to mount in the opening of prefabricated frames of the type described
above to selectively and removably mount all different types of separate inserts,
such as panels, glassed units with cross bars etc., in order to enhance the estetic
value of the interior fittings. If desired, the inserts can be easily interchanged,
so as to provide a flexible system.
[0004] If the insert is a panel, it is preferably divided into two sections, one section
comprising the entire raised portion, while the other section forms a border. After
the section with the raised portion has been inserted, it is locked by insertion of
the border through the groove which opens into said outer edge surface. Suitably,
the longitudinal edge of the border section can be inserted into a longitudinal groove
or slot in the raised portion of the associated section in order to conceal the joint
between the sections when in place as much as possible.
[0005] The inventive idea is also applicable to an interior fitting, in which the insert
is a cross or sash bar type glazed unit. The insert is divided into several sections,
also along at least one dividing line which when the insert is in place is essentially
parallel to the longitudinal axis of the member containing the groove opening into
the outer edge surface, the sections consisting both of panes of glass with a thickness
corresponding to the width of the grooves in the frame members, and of thicker cross
bars with longitudinal grooves for holding the edge portions of the panes of glass.
The last pane of glass is inserted through the through-groove in the frame to complete
and lock the entire unit in the frame.
[0006] As regards the prior art:
DE-B-2 301 213 reveals an interior fitting in the form of a frame and an insert mounted
in the central opening of the frame in the form of a panel for example. This design
makes it impossible, however, to replace or remove inserts in an already assembled
frame, since the assembly of the entire fitting, i.e. frame and insert, is done, as
in all similar conventional designs, at the same time.
[0007] PCT-publication WO 81/00589 reveals a glazed unit with cross bars, in which the panes
of glass after insertion of the cross bars in the frame are inserted into pocket-like
grooves in the bar and frame members, whereafter the panes are fixed with putty or
the like. This design does not permit simple, feasible removal or replacement of inserts
either, since fixed joints, i.e. a number of putty joints, would first need to be
removed.
[0008] DE-A-522 507 reveals a simple frame with a through-slot in one of the frame members,
through which slot a flat board can be inserted into the frame, the thickness of said
board nowhere exceeding the width of the grooves in the frame holding the board in
place. This frame does not of course permit after-insertion of an insert which is
thicker than the frame slot.
[0009] Two embodiments of the invention will now be described below in detail with reference
to the accompanying drawings. Fig. 1 is a perspective view of the back of a finished
frame of a cabinet door, in which an insert according to the invention can be mounted.
Fig. 2 is a cross-sectional view of the frame along the line II-II in Fig. 1. Fig.
3 shows an insert according to the invention in the form of a panel. Fig. 4 shows
a front view of the frame in Fig. 1 with the panel section of the insert inserted
in the frame with a border section of the insert shown in a position just prior to
insertion through the upper through-groove in the door frame. Fig. 5 shows a cabinet
door frame similar to that in Figs. I and 4 but with an insert in the form of a glazed
unit with cross bars, the last mounted pane being shown in a position for insertion
through the open groove in the upper frame member. Fig. 6 shows a cross-sectional
view along the line VI-VI in Fig. 5.
[0010] Fig. 1 shows an example of a frame, in which an insert 2 according to the invention
can be after-inserted or removed, in particular a frame for a cabinet door. The frame
I comprises an upper frame member 3, a lower frame member 4 and two opposite side
members 5 and 6. Frame members 3-6 define a central opening 7 and are provided with
grooves 8, 9, 10 and 11, respectively, on their edge surfaces facing the opening 7.
In contrast to the grooves 9, 10 and 11, the form of which is shown in more detail
i Fig. 2, the groove8 extends in the upper frame member 3 through the entire frame
member and forms a through-slot there.
[0011] Fig. 3 shows an example of an insert according to the invention in the form of a
panel 2, which is divided into two sections 12 and 13, one section 12 of which comprising
thin peripheral border portions 14a, 14b and 14c with a thickness corresponding to
the width of the grooves 8-11, and a raised panel portion 15 on the front of the insert
2. As can be seen in Fig. 3, if desired a corresponding or different raised portion
can also be made on the back of the insert, so as to make the insert 2 reversible
for selective insertion in the cabinet door frame 1. The section 12 can be provided
on its edge facing section 13 with a slot or groove 16 for receiving one longitudinal
edge of the section 13.
[0012] With reference to Fig. 4, we will now describe how the insert 2 can be mounted in
the frame 1. First, section 12 is inserted with its edge portion 14b from below into
the groove or slot 8 in the upper frame member 3 (see arrow A) until the lower edge
portion 14c of section 12 is placed directly over the groove 9 in the lower frame
member 4, whereafter the section is pressed downwards in the direction of arrow B.
Section 12 is then slid laterally in the direction of arrow C until the edge portion
14a strikes the bottom of the associated groove in the frame side member 6. Finally,
the second section 13 of the insert is inserted through the slot 8 in the top member
3 and into the groove 16 in section 12 and the groove 11 in the frame member 5 until
the lower edge of the section 13 strikes the bottom of the groove 9 in the lower frame
member 4. If required, the sections can be tensioned against each other by means of
suitable wedges or the like (not shown in the drawing) to lock the sections in the
frame and make the joint line between the border portions 14b and 14c of section 12
and the adjacent upper and lower portions of section 13 as inconspicuous as possible.
[0013] Although this embodiment of the insert according to the invention has been described
in connection with mounting in a frame of a cabinet door, it is of course possible
to apply the same idea to frames for other types of doors, shelf end-pieces and other
interior fittings.
[0014] Fig. 5 shows another embodiment of the invention, in which the insert consists of
a cross bar type glazed unit, which consists of four panes of glass 17, 18, 19 and
20, and cross bars 21, 22, 23 and 24, each of which has a groove 25 (Fig. 6) on opposite
longitudinal edges for holding the edges of the panes.
[0015] When installing this glazed unit, pane 18 for example can be inserted first into
its grooves in the frame members, whereafter the bar 22 is slipped over the free side
edge of the pane. Pane 19 is then inserted into the bar 22 and its grooves in the
frame pieces. The bars 21 and 23 are then put in place above the panes 18 and 19,
and the pane 17 is then inserted into the grooves in the bar 21 and in the associated
side and top members of the frame 1. Finally, the bar 24 is put in place and pane
20 is inserted through the open slot in the upper frame member to complete the glazed
unit and lock the individual components to each other. If desired, bars 21 and 23
or bars 22 and 24 can be made in one piece to facilitate assembly. The grooves 25
in the bars 21-24 and the grooves in the frame and/or edge portions of the panes 17-20
can also be provided with friction locking means (not shown) or the like to prevent
play and rattling between the parts of the entire unit.
[0016] As in the embodiment of the insert described first, the glazed unit can also be inserted
into a frame for another type of door or other interior fitting.
