IMPROVEMENTS IN DOORS
The invention relates to improvements in doors, particularly in doors which
include a window
light.
By window light is meant a window of glass, plastic or other transparent or
translucent
material which is mounted in an opening of a door. The window light may be of
a single, or
of a multi-layer, construction.
The door may be a wooden door, or of any other suitable material such as
plastic or a
combination of suitable materials.
Whatever the construction of the door, it is necessary that the window light
be firmly and
securely mounted therein, particularly when the door is a fire door. In the
past, window lights
have been mounted in an opening in a door using a plethora of mounts, each of
which
requires the use of securing means such as screws to be screwed into the
fabric of the door.
This can weaken the structure, and is in any event unsightly.
It is accordingly an object of the invention to seek to mitigate these
disadvantages.
According to a first aspect of the invention there is provided a set of parts
for assembly with a
door for mounting a window light in an opening in the door, the set of parts
comprising a
first bracket part for securing to the door and a second bracket part for
assembly with
the first bracket part to define a seating for the window light.

More specifically the present invention provided a set of parts for assembly
with a
door for mounting a window light in an opening in the door, comprising a first
bracket
part for securing to the door and a second bracket part for assembly with the
first
bracket part to define a seating for a window light, the first and second
bracket parts
each comprising a flange which when the parts are assembled are substantially
parallel and spaced apart to define the seating therebetween, the first
bracket part
having a main body part which when assembled with the door, extends over a
boundary of the opening and which has projections extending from the main body
part to embrace the door, the main body part having seatings for receiving
mountings of the second bracket part, the second bracket part being of
substantially
Z-shape and having a part which is adapted to embrace the door between the
projections of the first bracket part.
Using the invention it is possible to provide for mounting a window light
without the
need to screw screws into the door.
The first and second bracket parts may each comprise a flange which when the
parts
are assembled are substantially parallel and spaced apart to define the
seating
therebetween. This provides a relatively simple construction in which the
window
light may be mounted.
The first bracket part may have a main body part which when assembled with a
door,
extends over a boundary of the opening and which has projections extending
from
the main boundary part to embrace the door. This provides a positive securing
of the
assembled set of parts.
The main body part may have seatings for receiving mountings of the second
bracket part. This provides for an integrated assembly of the two bracket
parts,
particularly when the second bracket part may be of substantially Z-shape and
may
have a part which is adapted to embrace the door between the projections of
the first
bracket part.

The first bracket part may also comprise support means for entering the fabric
of a
door surrounding the opening. These support means are in use hidden so that
there
is no adverse aesthetic effect.
There may be an eject frame adapted to eject the window light in case of fire,
or
removal for replacement if a window light is damaged or is required to be
changed.

The bracket parts may be made of metal, particularly iron.
According to a second aspect of the invention there is provided a door
including an opening
for mounting a window light, and a set of parts as hereinbefore defined,
wherein the set
of parts are assembled to define a seating for the window light.
There may be a plurality, suitably four, spaced apart assembled sets of parts.
The window light may comprise a single or multi-pane window.
The door may be made of wood, and may suitably be a fire door.
A set of parts and a door embodying the invention are hereinafter described,
by way of
example, in the accompanying schematic drawings.
Figs. 1 to 4 show respectively first and second bracket parts for assembly
with a door for
mounting a window light in an opening in the door, Fig. 1 showing end
elevational views of
the first and second bracket parts from one elevation, Fig. 2 the first and
second bracket
parts from an elevation opposite to that of Fig. 1, Fig. 3 an elevational view
of the first bracket
part mounted on a door and Fig. 4 the first and second bracket parts assembled
together to
define a seating for a window light;
Fig. 5A and 5B show eight steps in assembly of the bracket parts on a
surrounding of an
opening in the door in which the window light is to be mounted;

Fig. 6 shows an elevational view of a door embodying an embodiment of the
invention;
Fig. 7 shows a section through the door of Fig. 6;
Fig. 8 shows an enlarged view of the mounting of the window light in the
opening; and
Fig. 9 shows an exploded view of a door according to an embodiment of the
invention.
Referring to the drawings, there is shown a door 1 such as a fire door (though
this is optional,
the door may not be a fire door) and a set of parts 2 for assembly with the
door 1 for
mounting a window light 3 in an opening 4 in the door 1, comprising a first
bracket part 5 for
securing to the door 1 and a second bracket part 6 for assembly with the first
bracket part 5
to define a seating 7 for a window light 3.
Both bracket parts 5, 6 are made of metal, such as iron, and are formed from
metal plate.
The first bracket part 5 has a body 8 which in use flanks part of the door
surrounding the
opening. Projecting from the bottom in use and as viewed of the body is a
flange 9 which
forms one part of the seating 7. The top of the body 8 has projections or legs
10 which
embrace part of the door surrounding the opening 4, and there are lower
equivalent
projections or legs 11 so that in use the legs 10, 11 embrace the door part
surrounding the
opening 4. There are also rearwardly (in a direction away from the opening)
spikes or
projections forming support means 12 which have a pointed end 13 and are
inserted into the
door, suitably in slots 14 therein. The second bracket part 6 is of
substantially Z-shape and
has a lower flange 15 which projects from a body 16 to be spaced from and to
be
substantially parallel to the flange 9 to define the seating 7. A flange 17
embraces the door 1

between the projections 10, and there are projections 18 with pointed ends 19
which engage
the door fabric through slots 20 in the body 8 of the first bracket part 5.
The assembled set
of parts, as shown in Figs. 4, 6, 7, 8 and 9 is thus a first, composite unit
which requires no
screws to fix it to the door.
As shown in Figs. 5A and 5B, the first bracket part 5 is mounted on the door,
"1", "2", a first
finish surround, trim or eject frame 20 is then mounted on one side of the
door, "3", "4", the
second bracket part 6 is then assembled with the first bracket part "5", "6",
and a second
finish surround, trim or eject frame 21 is then assembled "7", "8" to provide
a complete
mounting at the opening and in which the window light is mounted. There are as
shown in
Fig. 6, four assembled sets of parts 2 which do not require the use of screws,
or other fixing
means and as there are only four sets, the cost is reduced.
The eject trim 20, 21 covers the edge of the opening 4 for an aesthetic
effect, and covers up
the edge of the surround, including any openings= spaced therealong for
receiving the
projections.
