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.

, 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 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.

The lower window frame 5 is a member having a substantially T-shaped section, which is formed by a longi-tudinal plate 5b and a transverse plate 5c. And, the lower part of the panel 8 is mounted between the upper part of the longitudinal plate 5c and a batten 18. Further, the lower window frame 5 is vertically spaced apart from the upper body ` - 10 -.
~ .
~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 hook-shaped fastener 85 is fixed by welding to the upper part ~L3~9~27 of the fastener 83. A longitudlnal piece 85b of the hook-shaped fastener 85 is connected to the inner, lower portion of the lower window frame 5 by means of bolts 96a inserted in a groove 19 formed in the inner side of the lower window frame 5, and nuts 86b. Further, reference numeral 89 denotes a reinforcing plate welded to one side of the pair of L-shaped fasteners 82, 82.
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 ~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 ~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 ~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.
~3~92;~7 And, as shown in Figs. 8 and 11, the above-mentioned upper connecting metal fixture 20 comprises the first L-shaped bracket 37 fixedly secured to the upper, inner surface B
of the opening B of the building frame by means of the embedding bolts 36, and the second L-shaped bracket 38 connected to the first bracket 37 by means of the bolt 39.
The second bracket 38 is connected to the inner longitudinal plate 3a of the upper frame 3 by means of bolts 40 passed through and supported by the grooves 30 and nuts 41.
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 ~;~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 the reinforcing transverse member 21.
The above-mentioned reinforcing transverse member 21 is connected to the building frame as shown in Figs. 14 to 17.
; 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 of an auxiliary fastener 67 fixedly secured by an embedding .

fastener 66 thereto and a bolt 68. The upper part of the above-mentioned cantllever 23 is tightened up together with the auxiliary fastener 67 by means of the bolt 68. The lower part of the cantilever 23 is connected to the above-mentioned reinforcing transverse member 21 by means of an L-shaped bracket 69.
The opposed one ends of the pair of reinforcing transverse members 21, 21 is connected to the cantilever 23 by means of a pair of L-shaped brackets 69, 69 as shown in Fig. 15. The other end of each of the reinforcing transverse members 21 is connected to the cantilever 23 by means of another L-shaped bracket 69 as shown in Fig. 16.
The above-mentioned lower window frame 5 comprises the transverse plate 5c and the lon-gitudinal plate 5b, as shown in Fig. 8. The second lower transverse frame 4 is a hollow 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 ~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.

Further, the lower window frame 5 is vertically spaced apart from the upper body ` - 10 -.
~ .
~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 hook-shaped fastener 85 is fixed by welding to the upper part ~L3~9~27 of the fastener 83. A longitudlnal piece 85b of the hook-shaped fastener 85 is connected to the inner, lower portion of the lower window frame 5 by means of bolts 96a inserted in a groove 19 formed in the inner side of the lower window frame 5, and nuts 86b. Further, reference numeral 89 denotes a reinforcing plate welded to one side of the pair of L-shaped fasteners 82, 82.
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 ~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 ~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 ~3~9~
