ARRANGEME~T: FOR MOUNTING A WINDOW UNIT
TO A BUILDING FRAME
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an arrangement for mounting a
window unit to a building frame, and more particularly to an
arrangement for mounting a window unit in an opening of a
building frame through upper and lower connecting metal
fixtures fixedly secuxed to the upper and lower parts of the
opening of the building frame, and/or a reinforcing transverse
frame secured at an intermediate position between the upper
and lower connecting metal fixtures.
2. Description of the Prior Art
In a window unit which is generally used, an upper
framework and a iower framework are formed by assembling
an upper frame, a lower frame and left and right longitudinal
frames and disposing a transom transversely between the
longitudinal frames, and then a panel member is mounted
on each of the upper and lower frameworks thereby forming an
upper window unit and a lower window units.
: ~ 20 To mount the above-mentioned window units on a building
~ frame to construct an external wall; in other words, to
:~ construct a curtain wall with window units, mullions are
connected to the building frame, window units are mounted
` '~ '.`
,
13~922~
between the mullions, and window units are mounted through
fasteners onto the building frame.
Since such a window unit is formed by transversely
connecting an upper frame, a transom and a lower frame
between left and right longitudinal frames, it can be
mounted on a building frame by connecting the left and right
longitudinal frames to the mullions and the fasteners.
However in case a pc board is mounted on a building
frame, and a window unit, which is comprised of an upper
window unit and a lower window unlt which have separately
been assembled, is mounted in an opening formed in the pc
board, it is very troublesome to mount the longitudinal frames
in the opening of the building frame using mullions and
fasteners according to the conventional practice, because the
longtidinal frames need to be mounted in a narrow opening.
Further, in case the window unit is a transverse multiple
window, a long transom must be used which is liable to be
deformed or bent either in the indoor or in the outdoor
direction when it is subjected to a strong wind.
Further, as disclosed in Japanese Laid-Open Utility Model
~ Application No. SHO 60-83617, there is known a window unit
; wherein a lower transverse frame is disposed below a lower
window frame forming a window unit so as to form a wall-
through portion between the lower window frame and the lower
transverse frame, the arrangement being made such that the
-- 2 --
13~9;~27
outside air can be introduced through the through-wall
portion into the room.
In such a window unit, the lower window frame is
integrally formed with suspension plates, the suspension
plates are abutted against a lower frame, and the lower
window frame .is connected to the lower transverse frame,
thereby preventing the lower window frame from being deformed
or bent by the action of wind pressure either in the indoor
or in the outdoor direction. According to this arrangement,
however, the outside air inlet holes must be formed in the
suspension plates, and not only the fabrication becomes
troublesome~ but also the area of opening through which the
outside air is introduced is reduced wlth the result that the
; outside air cannot be supplied fully into the room.
To solve this problem, it is only necessary to dispose
the lower window frame apart vertically from the lower
transverse frame. However, by so doing, the longitudinal
ends of the lower window frame is connected and supported
only by the left and right longitudinal frames, and the lower
window frame cannot be supported directly by the building
frame, thus causing the lower window frame to be deformed or
bent by the action of wind pressure etc. either in the indoor
or in the outdoor direction.
This tendency becomes conspicuous, particularly in case
of a transverse multiple window wherein window units are
connected continuously in the transverse direction.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The present invention will now be described in detail
below with reference to the accompanying drawings.
In the first place, the first embodiment of the present
invention will now be described with reference to Figs. l to 5.
As shown in Fig. l, a window unit l has a framework 6
comprising left and right longitudinal frames 6, 6, an upper

~3~27
4a thus forming the above-mentioned wall-through portion 7.
A connection duct 71 is connected to the inner, lower portion
of the lower window frame 5 and the inner, upper portion of
the upper body 4a so as to draw the outside air introduced
through the wall~through portion 7 through the connection
duct 7 into an air--conditioning unit (not shown). Further,
the intermediate portion of the wall-through portion 7 is
partitioned with an insect or bird control net 70 fitted to
tne upper part of the above-mentioned upper body 4a and to the
lower part of the above-mentioned longitudinal plate 5b,
thereby preventing the ingress of insects or birds into the
connection duct 71.
The above-mentioned lower window frame ~ is connected to
a lower, inner surface B2 of the opening B of the building
frame by means of lower connecting metal fixtures 24.
As shown in Figs. 2 to 5, the lower connecting metal
fixture 24 comprises an embedding fastener 80 fixedly secured
to the lower, inner surface B2 of the opening B of the
building frame, and a pair of L-shaped fasteners 82, 82
fixedly secured, respectively, to the fastener 80 by bolts
81, 81. A longitudinal plate shaped cantilever fastener 83
is sandwiched between longitudinal pieces 82a, 82a of the
pair of L-shaped fasteners 82, 82 and tightened and connected
by means of a bolt 84. Further, a transverse piece 85a of a

The above-mentioned lower transverse frame 4 is
connected to the building frame A by tightening up an L-
shaped bracket 87, which is fitted to the lower body 4b bymeans of a bolt 88, together with the longitudinal pieces
82a of the L-shaped fasteners 82 and the cantilever fastener
83 by means of the bolt 84.
The above-mentioned upper transverse frame 3 has a bracket
38 fitted to the inner side thereof by means of bolts 41, and
the bracket 38 is connected by means of bolt 39 to a bracket
37 fixedly secured to the upper, inner surface Bl of the
opening B of the building frame by means of an embedding
bolt 36, thereby connecting the upper transverse frame 3 to
the building frame A.
Furher, the building frame A in the first embodiment is
a PC board.
Next, a second embodiment of the present invention will
be described with reference to Figs. 6 to 19.
As shown in Fig. 6, a window unit W in the second
- 12 -
~3~g2~7
embodiment consists of an upper window unit Wl, and a lower
window unit W2. The upper window unit W1 is a transverse
multiple window comprising a pair of rectangular Erameworks 6,
each of which is formed by an upper transverse frame 3, a
first lower transverse frame 9 and left and right longitudinal
frames 2, 2. The lower window unit W2 comprises a wall-
-through unit 12 having wall-through portions 7 formed by
connecting a transom 11, a lower window frame 5, and a second
lower transverse frame 4, which is connected to the frame 5
by a pIurality of supports or braces 10. The transom 11
comprises an upper transom 13 and a lower transom 14 which
are connected slidably in the longitudinal direction. A
plurality of mullions 15 are connected between the lower
transom 14 and the lower window frame 5, thereby forming a
transverse multiple window.
Further, the transom 11 may be formed integrally instead
of forming i-t by the upper and lower transoms, and also the
mullions 15 may be connected to the second lower transverse
frame 4 directly without provision of the lower window frame 5.
Stating in briefl the lower window unit W2 may be formed
by connecting the mullions 15 between the transom 11 and the
lower transverse frame 4.
Fig. 7 is a front view showing a condition that the
window unit W is mounted, looking from the indoor side. A
PC board A is mounted on the building frame, not shown, and
- 13 -
~L3~9227
the board A is formed with an opening B, in which the window
unit W is disposed. The indoor side of each of the upper
transverse frames 3 is connected to the upper, inner surface
Bl of ~he opening B of the building frame by means of a pair
S of upper connecting metal fixtures 20, 20. A pair of long
left and right reinforcing transverse members 21 are disposed
along the indoor side of the transom 11. The opposed one
ends of the pair of reinforcing transverse members 21, 21 and
the other ends thereof are connected through the fasteners 22
and the cantilevers 23, etc. to the upper indoor side surface
Al of PC board A having the opening B of the building frame
formed therein. The indoor side of the lower window frame 5
is connected through lower connecting metal fixtures 24 to
the lower inner surface B2 of the opening B of the building
frame. The indoor side of the upper transom 13 of the
transom 11 is connected to the above-mentioned reinforcing
transverse frames 21, and the first lower transverse frames
9 are connected to the upper transom 11. A panel 17 is
mounted in the framework 16, and a glazing 8 is mounted on
the outdoor side of the mullions 15.
Since the transom 11 is thus rigidly connected through
; the reinforcing transverse member 21, the cantilevers 23 and
the fasteners 22 to the building frame, there is no possi-
bility of the transom 11 being deformed or bent either in
indoor direction or outdoor direction.
~3~Z27
Further, since the indoor side of the upper transverse
frame 3 is connected to the building frame by means of the
upper connecting metal fixtures 20, and the indoor side of the
lower window frame 5 is connected to the building frame by
means of the lower connecting metal fixtures 24, the upper
window unit Wl and the lower window unit W2 can be rigidly
mounted in the opening B of the building frame. And, since
each of the window units Wl, W2 can be mounted in the opening
B of the building frame from the indoor side after the upper
and lower connecting metal fixtures 20, 24 and the reinforcing
transverse member 21 have previously been mounted, the window
units can be mounted simply and readily.
For example, the upper and lower connecting metal
fixtures 20, 24 are fitted to the upper and lower inner
surfaces Bl, B2 of the opening B of the building frame, and
the reinforclng transverse member 21 is fitted to the fasteners
22 and the cantilevers 23, and then the transom 11 formed by
the upper and lower transoms 13 and 14 which have been
previously assembled is inserted into the opening B so as
; 20 to connect the upper transom 11 to the reinforcing transverse
member 21.
Then, the framework 6 to which a panel 17 is mounted is
inserted in the opening B of the building frame from the
outdoor side so that the inner side of the upper transverse
frame 3 is connected to the upper connecting metal fixtures
- 15 -
~3~9~
20, and also the ~irst lower transverse frame 9 is connected
to the upper transom 13. Then, the wall-through unit 12 is
inserted into the opening B of the building frame from the
outdoor side so that the lower window frame 5 is connected to
the lower connecting metal fixtures 24. Thereafter, the
mullions 15 are connected to the lower window frame and the
lower transom 14, and then the grazing 8 is mounted on the
outer surfaces of the mullions 15.
Next, each of the component parts will be described in
detail.
As shown in Fig. 8, the upper transverse frame 3 is of a
substantially rectangular hollow shape and has an inner
longitudinal plate 3a formed with a recess or groove 30, and
an outer longitudinal plate 3b formed with a holding piece.
An engaging piece 32 formed on the upper part of the panel 17
is engaged with the holding piece 31 so that it may be swung
freely in the indoor and outdoor directions. The upper
transverse frame 3 and the first lower transverse frame 9 are
abutted by and connected to the left and right longitudinal
frames 2, 2. As shown in Fig. 9, each of the longitudinal
frames 2 is urged against through a sealing material 34 onto
the longitudinal, inner surface B3 of an L-shaped member 33
mounted on the opening B of the building member. As shown in
Fig. 10, the left and right adjacent longitudinal frames 2, 2
are pressed against each other through a sealing material 35.

The above-mentioned transom 13 comprises, as shown in
Fig. 8, an inner longitudinal plate 13a, and a transverse
plate 13b. The inner longitudinal plate 13a is formed with
a groove 42, and the transverse plate 13b has a downward
guide recess or groove 43 and a downward recess 44 formed
longitudinally therein. The lower transom 14 has a T-
shaped upstanding piece 45 and an upstanding piece 46 formed
thereon. The T-shaped upstanding piece 45 is slidably fitted
in the downward guide groove 43 and is provided with a roller
47 so that the lower transom 14 may be slidably moved
longitudinally relative to the upper transom 13. Further,
the upstanding piece 46 is fitted in the downward recess 44
and pressed against a sealing material 48 to thereby prevent
the ingress of rain water towards the inside of the room.
; The above-mentioned mullions 15 are connected to the
lower transom 14 and the lower window frame 5 by means of
- 17 -
~;~09~:27
connectors, not shown. As shown in Fig. 12, the longitudinal
edges of glazings 8 are adhesively bonded onto the outer
surfaces 15a of the mullion 15 by means of adhesive 49. The
upper and lower ends of the mullion 15 are supported, as
shown in Fig. 8, through sealing materials 50 inserted in the
recess 14a of ~he lower transom 14 and the recess 5a of the
lower window frame 5. As shown in Fig. 15, the terminal
mullion 15 is pressed against the above-mentioned L-shaped
member 33 through sealing materials 51. As shown in Fig. 8,
the above-mentioned transom 13 is connected by means of a
bolt 54 inserted in the recess 42 and a nut 55 to an L-
shaped bracket 53 fixedly secured by means of a bolt 52 to

; Stating in brief, the fastener 22 comprises an anchor
fastener 60, a primary plate-shaped fastener 61, a secondary
L-shaped fastener 62, and a pair of L-shaped pieces 63, 63
welded to the primary fastener 61 and the secondary fastener
62. An upper part 64a of an L-shaped bent longitudinal
plate 64 is connected to the secondary fastener 62 by means
of a bolt 65, and a lower part 64b thereof is located
opposite to the upper, inner surface Bl of the opening B of
the building frame and connected to the surface Bl by means

member having a substantially L-shaped section. The insect
control net 70 is fitted to the longitudinal plate 5b and the
upper part of the second lower transverse frame 4. The
- connection duct 71 is connected to the indoor side lower
part of the lower window frame 5 and the indoor side upper
part of the second lower transverse frame 14 so that the
outside air can be introduced through the wall-through
portion 7 into an air-conditioning unit, not shown. As shown
in Fig. 18, an aluminum panel plate 72 is fitted to the
indoor side of adjoining supports 10, 10, and also as shown
- 1 9 -
~3~Z7
in Fig. 19, the terminal support 10 is pressed agalnst the
above-mentioned L-shaped 33 through a sealing material 73.
Since the lower connecting material fixture 24 used
in this embodiment is identical to that described in detail
in the first embodiment, the description thereof is omitted
herein to avoid duplication.
Further, although the window units having the wall-
through portion have been described in the above-mentioned
first and second embodiments, it is needless to say that the
present invention is applicable to window units without
through-wall portions.
It is to be understood that the foregoing description
is merely illustrative of preferred embodiments of the
present invention, and that the scope of the present lnvention
is not to be limited thereto, but is to be determined by the
scope of the appended claims.
