United States Patent WINDOWS WITH ONE OR MORE METAL SECTION SASHES FOR THREE WINDOW PANES Sven Eric Persson, Malmo, Sweden (263 Park Ave., Youngstown 4, Ohio) Filed Aug. 5, 1957, Ser. No. 676,165
Claims priority, application Sweden Sept. 18, 1956 4 Claims. (Cl. 20-56.5)
The present invention constitutes a link in the endeavours to provide a window structure free from steam or moisture and possessing a good heat-insulating capacity. It is known to make a window with three window panes arranged with intervening spaces in one and the same sash or in interconnected sashes, the space between the middle sash and the outermost sash being larger than the space between the middle sash and1 the innermost sash. A difliculty met with in this window structure was to make the window panes free from moisture or steam, condensate forming on the sides of the panes facing one another, particularly in cold and moist weather.
The substantial distinguishing feature of the invention resides, above all, in that the middle pane and the innermost pane have their edges inserted into grooves in a sash section of metal common to both of said panes, said grooves being limited by mutually rigidly connected and preferably integral side portions, of which portions those located at the sides remote from one another are adapted for wedging in packing material against said sides remote from one another while being of such configuration and strength that hermetical sealing of the space between said panes may be attained by a wedge effect. Through the hermetical sealing of the innermost panes the formation of condensate in the space between them can be avoided, and this is facilitated by said space being made with a relatively small air volume and with a small content of moisture in consequence thereto. On the other hand, the outermost space may be made larger, particularly if it is caused to communicate with the atmospheric air, without any great risk of the formation of condensate being involved thereby. A larger outer space also brings about the advantage of the same being adapted to receive a screening contrivance, such as a roller blind, jalousie, Venetian blind or the like.
A comparatively good heat-insulation at the maintenance of the possibility of providing a window free from steam may be attained according to a modification of the invention involving that the middle pane extends only for a portion, such as the half of the height of the window sash. In cold weather it will prevent the cold body of air in the lower part of the outermost space from reaching the warmer inner space, and consequently brings about a relatively good insulation. If desired, the part pane in consideration may be arranged to be displaceable in its groove so as to permit of being pushed up into an upper position when sunshine becomes annoying, in which upper position it then serves as a shielding member. It should then be made from coloured glass, plastic or other suitable shielding material.
Further features of the invention will appear from the following description of forms of embodiment illustrated in the accompanying drawings. Fig. 1 shows a vertical section at right angles to, the plane of the window, and Fig. 2 shows a corresponding vertical projection of one half of the window which is symmetrical with respect toa vertical middle plane. Fig. 3 is a diagramsofter than the sash material.
2 matically represented perspective view of a modification with the middle pane extending only for a portion of the height of the sash.
In the embodiment shown in Figs. 1 and 2, the window consists of an inner sash 1 and of an outer sash 2 suspended thereon. Of a frame 3 only a lower portion and a lateral portion are indicated, but obviously the frame may be of an arbitrary suitable construction not calling for a more detailed description. The sashes 1, 2 are made from metal sections, namely, each one of a bent section extending as a strap along the lower edge and two side edges of the window, and of a. straight metal section bar extending at the upper edge of the window while being at the ends thereof united rigidly or removably with the upper ends of said strap. The suspension of the outer sash 2 on the inner sash 1 is provided by the top piece of the outer sash being formed with a hook-shaped portion 4 resting on a tightening fillet 5 on the top piece of the inner sash and embracing an obliquely inwardly directed flange 6 of said top piece.
The window has three panes provided therein, that is to say, an inner pane 7, a middle pane 8 and an outer pane 9. The intervening space 19 between the panes 7, 8 of the inner sash 1 is considerably smaller than the space 11 between the middle pane 8 and the outer pane 9. The wide space 11 is suited for the reception of a shielding contrivance, such as a roller blind, Venetian blind or jalousie permitting of being suspended on the top piece of the inner sash.
The inner pane 7 and the intermediate pane 8 have their edges inserted into grooves 12, 14 in the metal section common to both of said panes and constituting the inner sash. These two grooves are limited by mutually rigidly united or integral side portions. The side portions 15, 16 located at the sides of the panes remote from one another are adapted for wedging in packing strips 17 from plastic, for example, against said sides remote from one another, and are of a strength and configuration such that hermetical sealing of the intermediate space between the panes7, 8 can be obtained through a wedge effect. The side portions 15, 16 are formed with edges 18 set obliquely to the panes and forming together with the sides of the panes wedge grooves for the packing material 17. The grooves 12, 14 have a common side portion between the panes 7, 8, and this side or middle portion 19 carries packing material 20, which is It is compressed from opposite directions, when the packing strips 17 are pressed into the wedge grooves, so that a tightening effeet is obtained simultaneously on both sides of the two window panes.
The outer pane 9 is located in a groove 21 in the metal section of the outer sash, and this groove has a side portion 22 on one side thereof, said portion 22 forming together with the outside of the outer pane a wedge-shaped tightening space for the reception of a packing strip 23 from plastic or the like. A packing strip 25 may be fitted into a suitable groove in the opposite side portion 24 of the groove 21.
In the modification shown in Fig. 3, the intermediate pane 8' extends only for a portion of the height of the pane 9 from the inner pane 7. When displaced into its uppermost position or some intermediate position it may be used as a shielding device against sunlight.- It may be made from glass, plastic or other transparent or semitransparent material, which may be coloured, if desired.
I claim:
1. A window comprising an inner and an outer metallic window sash, means removably supporting said outer sash on said inner sash in heat-insulating relationship, window panes secured circumferentially in' said sashes in parallel spaced relationship, said inner window sash having therein two grooves for the insertion of an inner window pane and an intermediate window pane, the outer edge of the groove for said inner window pane being provided with an outwardly extending taper, the outer window sash having therein a groove for the insertion of an outer window pane, said groove being provided on its outer edge with an outwardly extending taper, the distance between the outer window pane and the intermediate window pane being substantially larger than the distance between the intermediate window pane and the inner window pane, said intermediate window pane extending only for a portion of the height of the sash and displaceable in a vertical direction, and packing material to seal the gap between said window panes and the edges of the grooves adapted for hermetically sealing the space between the window panes by a wedge efiect.
2. A window according to claim 1, characterized in that the side portions of the sash grooves located at the sides of the two innermost panes remote from one another have edges set obliquely to the panes, said edges forming wedge grooves for packing material, and that an intermediate portion of the sash material separating the grooves for the edges of said panes carries packing material, which is softer than the sash material and adapted to be compressed from opposite directions by the innermost panes, when packing material is wedged into said wedge grooves.
3. A window according to claim 1, characterized in that the outermost pane is located in a groove in a special metal section which is suspended on the sash section carrying the innermost panes, said groove having on one side thereof a side portion, which together with the outside of the outer pane forms a wedge-shaped tightening space for the reception of packing material.
