6 Claims.

My present invention relates to new and improved screening means for windows.

An object of my invention is to provide a screen for windows the main feature of said screen being that it is extremely simple and yet eifective and durable.

Another object of my invention is to provide a screen of the type indicated which leaves the View through the window unobstructed.

A further object of the invention is to provide a screen of the type indicated which is automatic in its function, so that the window can be closed and opened to a certain extent without interfering with the function of the screen.

Still another object of my invention is to provide a screen of the type indicated in which said automatic function is brought about Without the use of any rollers or other means for housing the screen or part of it in closed or partly opened positions of the window.

A further object of my invention is to provide a screen of the type indicated, which is readily mounted and dismounted, and which can also readily be detached either from the window frame or from the window sash, or from both, in order to enable the window to be opened further than allowed by the screen, when in its effective position.

Still another object of my invention is to provide a screen of the type indicated which has an inherent tendency to bend, or bulge, in the proper direction when the window is being closed.

The invention is illustrated diagrammatically in the accompanying drawing, in which:

Fig. 1 shows a pespective View of a screen device for a pivoted window according to the invention,

Fig. 2 shows a sectional View of the top pieces of the window and screen with the sash in closed position,

Fig. 3 shows a sectional view of the bottom pieces of the window and screen with the sash in closed position,

Fig. 4 shows a sectional view of a slightly modified top piece with the sash in opened position,

Figs. 5 and 6 show sectional views of the side pieces of the Window and screen above and below the pivots, respectively, with the sash in closed position, and

Fig. 7 shows a perspective View of a member of the screen, certain parts being cut away for the sake of clearness.

In the embodiments of my invention shown in the drawing, the screen is applied to a window, the sash I of which is mounted to pivot in a frame 2 on a central horizontal axis, as indicated in Fig. l. This type of window is, of course, selected only as an example, the use of the screen according to my invention being by no means limited to said window type.

The screen according to the drawing comprises parts 3, 4, 5 and 6, l, 8 covering all the openings between the frame and the sash, thus leaving the view through the window pane entirely unobstructed. Each part 3, Il, 5, 6, l, 8 of the screen can form a separate member connected with one or more of the other members by any suitable means which may or may not be releasable. In another embodiment, the parts 3, 5 are made of one continuous piece of material and the parts 9, 'I, 8 of another piece of material, both pieces being arranged in a suitable way at the corners in order to permit the necessary movements of the screen.

Each part of the screen comprises a piece of netting 9 (Fig. '7), preferably of cloth, and said piece is provided along its longitudinal edges with linings I0, II carrying suitable means for detachably securing the screen to the window frame 2 and the window sash I, such as press buttons I2 and I3, respectively, or Zippers, etc.

Said pieces of netting Si are further provided with cross strips of fabric I4 or any suitable ma teria] secured to the netting 9 by means of stitchings I5, I6. In between said netting E and said strip of fabric I4 a thin elastic steel strip I'I is provided having an inherent tendency to occupy a curved shape or at least a tendency, when forced to occupy a curved position, always to bend in the same direction. This can be accomplished, for instance, simply by making said steel strip Il curved also in cross-section. It then has a tendency to bend to its concave side, when at all forced to bend.

In order further to ensure said bending, or bulging, in the desired direction, the longitudinal edge portions of the screen, or the linings It, II, are secured to the window frame 2 and the window sash I in a certain way. As shown in Fig. 2, one edge portion I 6 of the screen 4 is fastened to the lower surface of the top member of the frame 2 with the edge of the screen facing outwards, i. e. to the left in Fig. 2. The other edge portion II of said screen 4 is secured to the inner surface of the top piece of the sash I with the edge of said screen facing upwards.

At the bottom of the window, a s shown in Fig. 3, the edge portions Iil and I I of the screen 'I are 5 secured to the bottom pieces of the frame 2 and sash I, respectively, with both edges of said screen 'I facing downwards.

Figs. 5 and 6 show the mounting of the screens 3 and 6, respectively, at the side members of the window above and below the pivots, respectively. As shown, the edge portions I0 and II of the screens 3 and 6 are secured to the frame 2 and sash I, respectively, with the edges of the screens facing away from the centre of the window both above and below the pivots of the window. In Figs. 2 to 6, inclusive, the direction of movement of the sash is indicated by an arrow A.

In Fig. 4, corresponding to Fig. 2 but with the sash I in opened position, a member I8 is shown secured to the sash I for the purpose of making the screen 4 bend evenly thus avoiding sharp bends which would be likely to damage the screen. Similar devices can, of course, be used at every point where bending of the screen occurs, when the window is being opened as, for instance, at I9 in Figs. 5 and 6.

The screen can, of course, be attached to the window members in other ways than as shown and described, the general feature being that it is attached in a manner to facilitate its bending, or bulging, in the proper direction, when the window is being closed.

Instead of the steel strips l'I and its holding means I4, strips and holding means of any other suitable type and material can be used, such as leather strips stitched to the screen material, etc. The screen members 3, 8, 5, 8 can be made rectangular or tapering towards the pivots of the window, and at said pivots said screen members can, if necessary, readily be closed by any suitable means, such as inserted screen pieces stitched on, etc.

It should be obvious that the embodiments of my invention shown in the drawing and described above are only for the explanation of the invention and must not in any respect be regarded as limiting the scope thereof, since numerous modications of said embodiments are feasible without departing from the spirit of my invention.
