The present invention relates -to an o~lter frame or covering or
~acing a wall opening ~or a door or the like. The frame comprises a
covering or liner located ahaad of the soffit of the wall opening, and at
least one covering located on the ~all surface at right angles to the edge
of the liner. The covering, on the not-visible inner side thereof facing
the wall surface, is provided with fastening pins which extend at right
angles to this inner side for connection with the wall. Furthermore, the
liner has a fastening connection which is capable of being inserted.
Canadian Patent 9~5,9~1 discloses an outer frame which is intended
for a door and is provided with a grooved covering and an ornamental or
decorative covering, both of which comprise relatively thick-walled wood
strips or panels which haYe blind holes on the inner side, facing the wallJ
for receiving dowels which can be inserted in blind holes in the wall.
The fastening of the liner, which likewise consists of a wood strip or panel,
is effected at the edges of the liner, likewise via dowels which can be
inserted in blind holes of the liner and of the coverings. With old wood
doors already existing in buildings, especially varnished doors, the surface
of the wood parts, which has been damaged or has become unsightly, is
frequently replaced by a new surface of durable foil-like syn~hetic material
or of natural wood veneer. ~Yhile an old door panel can be refinished or
renovated relatively easily in a shop by known covering with a synthetic
material foil, it is difficult and expensive to provide a rigidly installed
old wood frame with a surface covering of synthetic material foil for
conforming the surface thereof to the new door panel surface, especially when
the surface of the old wood frame is wavy or damaged. If the old wood frame r
with a simple replacement of the old door panel by a new door panel hclving a
- 1 -
natural ~ood surface, likewise is to have a matched surface o:E natural
wood veneer, then the old wood frame must be broken out of the wall opening
for subsequent veneering in a shop or for replacement by a completely new
frame, which causes considerable remodeling dirt, and usually requires a
restoration of the da~aged wall surfaces. In practice it is often the case
that old, usually lacquered steel frames existing in buildings, on the
occasion of the renovation of the old wood door panels, likewise are to
receive a conforming new surface of durable synthetic material, for instance
in a wood decor or of natural wood foil. It is known to cover the coverings
0 and also the liner of an old wood frame with a covering which consists of
U-shaped holding strips, for example of metal, which are fastened with
screws or nails in the form of a frame to the edges of the old frame, and
between which fitting wood plates or panels with the new sur~ace are installed.
This method is costly and cumbersome, especially with respect to an exact
mounting of the covering; furthermore, this method cannot be used for
covering an existing old steel frame.
It is an object of the present invention to provide a Erame with
which an existing old wood frame as well as an existing old steel frame
can be covered for the purpose of surface renovation with the least possible
mounting work and generation of dirt; the frame should also be suitable, for
example in new buildings, as the initial frame for a still uncovered wall
opening.
According to the invention there is provided a frame for covering
an opening in a wall, and specifically for covering the soffit surface of
said wall opening, and that part of at least one of the t~o wall surfaces
adjacent said so~fit surface, said frame comprising:
a liner located ahead of, i.e., spaced from and substantially
parallel -to~ said soffi-t surface;
at least one covering respectively located on one of said two wall
surfaces at right angles to an adjacent edge of said liner; each covering
comprises a U-shaped, thin-walled profiled member having a base which is
substantially parallel to an associated wall surface, and two legs which
; extend perpendicular to said base; one leg of each of said profiled members
faces said wall opening and projects beyond the plane oE said soffit surface;
said liner being mounted on the outer side of said one leg; each of said
profiled members, on that side of said base thereof which ~aces the associated
wall surface, being provided with ~t least one rail which extends in the
longitudinal direction of said profiled member;
fastening dowels, each of which has an enlarged end which is
adapted to be received by said rail in such a way as to be movable therein
and to project at right angles therefrom toward the associated wall surface;
that end of each of said fastening dowels remote from said enlarged end
thereof being adapted to be inserted in bores operatively associated with
said wall surface for effecting connection of said profiled member with
said wall surface; and
connection means for securely holding said liner on said one leg
of said profiled member.
In the accompanying drawings:
Figure 1 is a cross section of one embodiment of the inventive
frame covering an existing old wood frame, and
Figure 2 is a cross section of another embodiment of the inventive
fral~e for covering an existing old steel frame.
Starting from a frame of the initially men-tioned general type, the
frame of the present invention is characterized primarily in that the
covering compris~s a U-shaped thin~walled pl~o~ile sheet or plate which on the
inner side of its base has at least one rail which extends in the
longitudinal direction of the profile sheet, and which receives -the enlarged
end of fastening dowels which can be moved in the rail and can be inserted
into bores on the wall side; that leg of the profiled sheet which faces the
opening in the wall projects beyond the plane of the soffit of the wall
opening, and the liner is placed or mounted on the outer side of this leg
and is held securely by the insertable fastening connection.
~Vhen the inventive frame is used for normal room doors, with which
the frame as a rule has two coverings - one on each side of the opposite
wall surfaces - each of the two coverings comprises a profiled member
constructed in accordance with the present invention. The profiled sheet or
plate can, to fulfill different desires, be produced, for example, of
aluminum with a color-anodized metallic surface, or, with ~he aid of
conventional coating techniques, can be produced with an adhesively bonded
surface of synthetic material foil or even of wood veneer. The open cross
section of the profiled sheet can be dimensioned large enough that the most
frequently used widths and thicknesses of the covering parts of the old
wood frames can be covered with a single standard model of the inventive
profiled sheet. For an invisible fastening of the profiled sheet, only
that covering part of an existing old wood frame which is to be covered
needs to be provided with several bores for the fastening dowels. Such
bores are drilled easily and simply along a line on the old covering part
and in alignment with the rail of the profiled sheet, The fastening dowels
can be shifted in the rail of the sheet to any desired locations, for
example when during drilling a hidden nail or the like is encountered in the
-- 4 --
old co~ering part~ and a ne~ ore mllst be drilled along -the line which is
aligned with the rail, ~en the frame is, or example, to be utilized for
a new building, the profiled sheet can be fastened directly to the wall,
whereby -the fastening dowels, which are dimensioned sufficiently long, can
be inserted directly into bores drilled in the wall surface; here too the
fastening dowels can be shifted to the appropriate location in the rail of
the sheet in the event that during drilling a wall joint is encountered
which is not sufficient for holding a fastening member, and a new wall bore
must be drilled along the fixed line at a different location. After
fastening the profiled sheet, or in case a frame is used having two coverings,
after the fastening of both sheets, that leg of the profiled sheet which
faces the wall opening and projects beyond the plane of the soffit of the
wall opening, forms an abutment for the liner of the inventive frame, so
that the liner can be placed on this leg independently of unevenness of the
wall opening soffit which is to be covered in a new construction, or of the
liner part to be covered in an existing old frame, and so that the liner can
rest fully and free of any joints on this leg. The liner of the frame
according to the present invention, when the profiled sheet has a surface
coating of synthetic material foil or wood veneer, can be a wood plate or
panel with identical surface coating, or, when a metallic color-anodized
aluminum surface is desired for the profiled sheet, the liner can comprise
a wood plate with a surface of similarly appearing aluminum foil.
According to further advantageous embodiments of the present
invention for the insertable fastening connection for holding the liner of
the frame, that leg of one of the profiled sheets which faces the wall
opening projects at least as far as into the plane of the surface of a blind
- 5 -
or spacing liner of wood arranged a~ the ~all opening sof-f:it; the liner placed
on this leg has, at least on its inner side a wood plate which has blincl holes
on the inner side thereof for receiving connecting dowels which can be
inserted in bores of the blind liner.
That leg of one of ~he profiled sheets which faces the wall opening
may be formed as a groove or recess for a door abutmentl and on its grooved
surface which serves as the door abutment surfaceJ may have a groove-liXe
receiving pocket which projects below the liner and into which pocket ~he
fastening rib of a profiled sealing member can be inserted which covers that
edge surface of the liner which terminates flush with the grooved surface of
the leg.
The sealing member may have a bent or angled-off portion at the
edge of its grooved surface, which angled-o:Ef portion forms an insert groove
with the receiving pocket for securely receiving and holding ~he edge of the
liner; the frame may have a second U-shaped profiled plate or sheet which
forms a second covering and which has an insert groove formed by a bent or
angled-off portion of its edge, ahead of that leg thereof which faces the wall
opening, for securely holding and receiving the other edge of the liner.
Referring now to the drawings in detail, the old wood frame which
is illustrated in Figure 1 and which is to be covered comprises: two facing
or covering parts 1 and 2 which are disposed on both wall surfaces 3 of a
w211; and a covering or lining part 4, which lines or covers the wall soffit
surface 5. The edge of the old frame formed by the covering part 1 and the
lining part ~ is made as a right-angle groove or recess 6 for a door abutment
in the usual manner. The outer frame according to the present invention
correspondingly also comprises three parts, including two coverings and one
-- 6 --
liner ~. The coverings each comprise a U~shaped, thin-walled profiled sheet
or plate 7 or ~, which on the inner side of the:ir base 10 each have a rail
or trac~ 11 e~tending in the longitudinal direction of the profiled member.
'rhe rail 11 receives the enlarged end of each of several fastening dowels 1~,
which ends are adapted to the open cross section of the rail. The fastening
dowels 12 can be moved in the rails 11, and can be inserted into matchingly
drilled bores 13 in the old covering part 1 or 2 which is to be covered. The
bores 13 are drilled along a line which is aligned with the rail 11; -this
line is disposed in such a way that those legs 14 of both of the profiled
sheets 7 and 8 which face the opening in the wall project beyond the plane
of the soffit of the inside wall openings. In the embodiment of Figure 1,
the lining part 4 of the old wood frame forms the soffit of the inside wall
opening, and the legs 14 of the profiled members project at least as far as
into the plane of the surface of the old lining part 4. As a result, the
liner or covering 9 of the inventive frame can be placed or mounted fully
and free of any joints on the leg 14 of the profiled member before an
engagement of the liner 9 occurs with the old lining part 4. The old lining
part 4 can also be used as a blind liner-like base for an insertable
fastening of the liner or covering of the frame according to the present
invention. In addition to this, the liner 9 - which for covering the old
lining part 4 need not be U-shaped and therefore can compromise a standard
wood strip, or at least on the inner side can have a wood plate or panel -
according to a further structural feature of the frame of the present invention
is embodied with blind holes or bores 16 on the inner side of the wood strip;
these bores 16 receive the connecting dowels 17. The connecting dowels 17 can
be inserted in matchingly ar~d identically correspondingly dTilled bores 18
-- 7 --
~ii2~
of the old lining part 4. The fastening dowels 12 and the connecting dowels
17 are advantageously synthetic material, ribbed or finned dowels which only
need to be driven into the bores by the respecti~ely necessary extent, and
bind or catch in the bores with their ribs or fins in a barbed manner with
high resistance against removal or tearing-out. The legs 14 of the profiled
sheets or plates 7 and 8, which legs project beyond the plane of the sur-Face
of the old lining part 4, are advantageously of such a length that they
partially cover the surface of the old lining part 4, and are provided with
holes for nails or screws 15. As a result, the legs 14 of the profiled
members can be fastened to the old lining part ~ at locations whlch are
covered and hidden by the installed liner 9, and can be fastened to the old
liner part 4 in such a way that with the use of only one rail 11 on the inner
side of the profiled sheets 7 and 8, a tilting of the sheets about the
fastening dowels 12 is avoided.
With the utilization of the embodiment of the frame illustrated
in Figure 1, for example in new buildings in which no old wood exists, only
a single blind or spacing liner consisting of a rough wood board needs to
be securely arranged on the soffit 5 of the wall, without costly alignment,
in order to be able to fasten the liner or cover 9 on this blind liner by
means of the connecting dowels 17. The fastening of the profiled sheets 7
and 8 is then effected via bores which are drilled directly into the wall
surfaces 3 and into which appropriately longer fastening dowels 12 are
inserted.
The profiled sheet 7, which serves as a so-called grooved
covering~ is, in a manner similar to that edge of the old wood frame which is
formed by the parts 1 and 4 and is to be covered, formed as a groove or
-- 8 --
2~
recess ~or a door abutment at that leg 1~ of the profiled member which faces
the wall opening, so that this leg 1~ has a grooved surface 20 which serves
as a door abutment surface. According to a further structural feature or
embodiment of the present invention, this leg 1~ of the profiled member 7
is constructed in such a way that at its grooved surface 20, the leg 14 has
a groove-like receiving pocket 21 which projects below the correspondingly
recessed liner 9. The fastening rib of a profiled sealing member 22 can be
inserted into this recess or pocket 21. The sealing member 22 is of such
a width tha* it covers that edge surface of the liner 9 which is flush with
the grooved surface 20 of the leg 1~ of the profiled member 7. As a result,
the liner 9 can be pre-fabricated to such a width that it can be used for
different wall opening soffit widths in new bulldings, or for difEerent
liner part widths of existing old wood frames; the liner 9 need only be cut
to the necessary fitting width when ready for mounting on the frame on the
grooved edge thereof. The cut surface is covered by the profiled sealing
member 22, and no longer needs to be provided subsequently with a new
surface covering.
Figure 2 shows another inventive embodiment of the outer frame,
which can be produced especially economically, and which makes it possible
to cover an existing old steel frame 26, though :it can also be used equally
well in new buildings for covering a still rough or unfinished wall opening.
The coverings or linings, as with the embodiment of Figure 1, comprise U-
shaped, thin-walled profiled sheets or plates 7' and 8'. However, the rails
11' arranged on the inner side are displaced or offset laterally to such an
extent that the bores which receive the fastening dowels 12' in each case can
be drilled in the wall laterally from the old steel frame 26. The proflled
_ g _
sheet 7, which serves as a grooved covering, has, as in the embodiment of
Figure 1, a grooved surface 20', as a door abutment surface, on its leg 14',
whicll projects beyond the plane of the soffit of the inside wall opening
formed by the old steel frame 26. ~n this surface 20' is arranged a groove-
like receiving pocket 21' which projects below the liner 9' for the fastening
rib of a profiled sealing member 2~'. The sealing member 22 according to the
present invention, along the edge of its grooved surface 20' has a bent or
angled-off portion 27 which with the receiving pocket 21' forms can insert
groove 23 for securely mounting the edge of the liner 9'. The o~her profiled
sheet or plate 8', which forms the second covering of the frame, is provided
ahead of its leg 14', which likewise projects beyond the plane of the wall
opening soffit, with an insert groove 25,formed by a bent o.-r angled-off
portion 24 of the edge, for securely mounting the other edge of the liner 9'.
After fastening both of the profiled sheets 7' and 8', the liner
9' is placed on the leg 14' of the sheet 8', which leg 14' advantageously is
somewhat longer than the angied-off edge portion 24~ and the liner 9' is
pushed into the insert groove 25. Thereafter, the sealing member 22' needs
only to be inserted in the receiving pocket 21', whereby simultaneously the
other edge of the liner 9' is placed on that portion of the leg 14' of the
sheet 7' which forms the receiving pocket 21', and is pushed into the insert
groove 23. Thereafter, the liner 9' is supported and securely held at that
distance from the old steel frame 26 desired for an exact alignment thereof
In order to avoid a tilting of the profiled sheets 7' and 8' about the
fastening dowels 12', the legs 14' can be fastened to the old steel frame 26,
for example, by a contact adhesive or, in a manner similar to the embodiment
of Figure 1, by driven-in connecting means. Driven-in connecting means on
the leg 14' of the sheet 8' are covered by the liner 9' so as to be no longer
- 10 -
~24~
visible. Connecting llleans driven-in on the leg 141 of the sheet 7' can be
co~ered by an additional sealing lip 28 of the sealing member ?2 I SO as to
be no longer ~isible.
The present invention is, of course, in no way restricted to the
specific disclosure of the specification and drawings, but also encompasses
any modi~ications within the scope of the appended claims.
