In Sweden FebruaryZO, 1937 4 Claims. (01. 20-53) inwindows having coupled sashes. I The main object of my invention is to provide a window of the type' referred to, and of such design as to make both surfaces of the two panes My present invention relates to improvements of the window easily available from within the room in order to facilitate the cleaningand polishing of said surfaces. With this main' object in view, the windowaccording to my invention is characterized by the fact, that the sash positioned on the outside when the window is in its closed'position, is hingedly connected to the inner sash at the lower edge-of said sashes, said inner sash being rotatabletol5 gether with the outer sash, which is mountedfto be rotated in the windoW-openingabout horizontal pivots provided approximatelyat the mid I dle of the height of the window, or'preferably slightly below said level, the rotation of the com the vertical members of the window-sashes facing each other, said recesses housing struts pivoted at one end to one of the sashes, and at-the other end tothe other sash, and serving to main- 35 tain the outer sash separated from the inner sash, when the window occupies its turned-over position.

An embodiment of the invention is illustrated, by way of example, in the accompanying draw- 4 ing, in which:

Fig. 1 shows a window according to the invention in closed position and viewed from within the room,

Fig. 2. shows, on an enlarged scale, a vertical 45 sectional .view on line IIII of Fig. 1, with the window in its closed position,

Fig. 3 shows a similar vertical sectional view with the window turned-over, and with the outer window-sash separated from. the inner one, i g

50 Fig. 4 shows, on an enlarged scale, a detail horizontal sectional View through the windowframe and the window-sashes on line IV-IV of Fig. 1, and

Fig. 5 shows a similar sectional view on line 55 Of Fig. 1. i

--In the drawing, I is a window-frame, in the opening of which a, window having coupled sashes 2 and 3'is, rotatable about a horizontal axis in a direction to move its upper edge into the room.

The window is rotatable on hinges comprising 5 two horizontal pivotstuds 4 secured to the inner sash 2, and'bearingmeans 5 for said studs 4 se curedto the Window-frame I. The pivot studs 4 are positioned approximately in the plane of the inner surface of the inner sash 2 and slightly 10'- below the central-line between the upper and lower edges of the window, so as to enable the coupled sashesto be swung round approximately half a revolution about the pivot studs 4, the upper edges of'the sashes thereby moving inwards 1 5 and downwards and the window being positioned substantially inside] the window-opening upon completion of said swinging movement.

The two coupledwindow- sashes 2, 3 are connected to each other by means of hinges 6 at the lower edge of the'window when closed (i. e., the

' edge parallel to the axis of rotation 4-4 and nearest. to said axis), and at the opposite edges the sashes are coupledby means of coupling catches .1 adapted to be operated bypins, or shafts, projecting from thejoint between the two sashes. The two sashes 2,. 3 are provided in those members perpendicular to the axis of rotation 4-4, and in the surfaces of said members facing each other, with longitudinal recesses 8, ID in which-struts 9 are positioned, said struts being pivotally and .displaceably connected at one end to one of the sashes and pivotally connected at the other end to the other sash, and serving to retain the outer sash 3 in a position separated from the inner sash, as shown in Fig. 3.

The two vertical joints between the Windowframe and the sashes are covered by tightening, or caulking, ribs the portions l2 of said ribssituated above the pivot studs 4 being fixedly connected to the inner sash 2 and, for instance, provided with a longitudinal projection, or a flange, l3 (Fig. 4) extending into a groove l4 provided in the window-frame, while the portions l5 of said tightening ribs are secured to the frame I and have a longitudinal projection l6 engaging a groove I! in the inner sash 2 (Fig. 5). The window is retained in a closed position by means of a locking device I8 or an espagnolet.

It should be obvious from the above description that, when desirable to clean or polish the window, said window ought to be rotated approximately on its horizontal studs 4, the-outside of the outer panethen facing towards the interior of theroom and being easily accessible from within said room. When it is desired to polish the surfaces of the panes facing each other in the two sashes, the catches I are released and the outer sash 3 separated from the inner one by rotating it upwards about the hinges 6, as shown in Fig. 3, the surfaces of the panes facing each other then being easily polished from within the room.

I claim:

1. A window comprising a frame, an inner sash adapted to fit in said frame, lugs extending inwardly from said frame and sash, studs connecting the inner ends of said lugs for connecting the sash to said frame for pivotal movement about an axis spaced inwardly from said frame, an outer sash juxtaposed to said inner sash, a hinge connecting the lower edges of said inner and outer sashes, said lugs being positioned ata point slightly below the middle of the height of said sash and frame so that both of said sashes may be rotated as a unit about the pivotal axis through an angle of approximately 180 to bring both sashes on the inner side of the room with the hinge at the top, and means for detachably coupling the non-hinged horizontal edges of said sashes to enable them tobe separated when on the inner side of the frame for access to the facing surfaces of the sash.

2. A window comprising a frame, an inner sash adapted to fit in said frame, lugs extending inwardly from said frame and sash, studs connecting the inner ends of said lugs for connecting the sash to said frame for pivotal movement about an axis spaced inwardly from said frame, an outer sash juxtaposed to said inner sash, a hinge connecting the lower edges of said inner and outer sashes, said lugs being positioned at a point slightly below the middle of the height of said sash and frame so that both of said sashes may be rotated as a unit about the pivotal axis through an angle of approximately 180 to bring both sashes on the inner side of the room with the hinge at the top, and means for detachably coupling the non-hinged horizontal edges of said sashes to enable them to be separated when on the inner side of the frame for access tothe secured to said frame and for connecting the sash to said frame for pivotal movement about a horizontal axis, an outer sash juxtaposed to said inner sash, a hinge connecting the lower edges of said inner and outer sashes, said pivot means being positioned at a point slightly below the middle of the height of said sash and frame so that both of said sashes may be rotated as a unit about the pivotal axis through an angle of approximately 180 to bring both sashes on the inner side of the room with the hinge at the top, and means for detachably coupling the non-hinged horizontal edges of said sashes to enable them to be separated when on the inner side of the frame for access to the facing surfaces of the sash.

4. A window comprising a frame, an inner sash adapted to fit in said frame, pivot means secured to said frame and for connecting the sash tosaid frame for pivotal movement about a horizontal axis, an outer sash juxtaposed to said inner sash, a hinge connecting the lower edges of said inner and outer sashes, said pivot means being positioned at a point slightly below the middle of the height of said sash and frame so that both of said sashes may be rotated as a unit about the pivotal axis through an angle of approximately 180 to bring both sashes on the inner side of the room with the hinge at the top, and means for detachably coupling the non-hinged horizontal edges of said sashes to enable them to be separated when on the inner side of the frame for access to the facing surfaces of the sash, the vertical members of said sashes having recesses in the surfaces facing each other and struts housed in said recesses, said struts being operable to hold said sashes spaced apart when uncoupled.
