4 Claims.
Mly present invention relates to a window screen which can be adapted for use with all types of windows.
An object of my invention is to provide a screen of the type indicated which is automatically operated by the opening and closing movements of the window.
Another object of my invention is to provide a screen of the type indicated adapted to be readily attached to and detached from the sash, while the screen is permanently connected with the frame, or vice versa.
A further object of my invention is to provide a disappearing screen of the type indicated, i. e. a screen which, when not in use, is more or less completely concealed within the frame or within the sash.
Still another object of the invention is to provide a screen of the kind indicated consisting of a number of screen members, which'are substantially slat-shaped and hingedly interconnected so as to form a screen which is foldable like an accordion.
Some embodiments of my invention are described below with reference to the accompanying drawing, in which:
Fig. 1 shows part of a screen,
Figs. 2, 3, 4, and show diagrammatically different types of connections between screen members,
Figs. 6, '7, 8, and 9 illustrate diiferent kinds of corner joints in screens covering window openings in more than one plane, and
Fig. illustrates diagrammatically how one embodiment of my invention can be applied to a certain window type.
In the embodiments of my invention shown in the drawing the screen comprises a number of screen members, three of them being shown partially at I, 2, and 3 in Fig. 1. In this case the screen is made of netting, as indicated in the drawing, and in order to make it occupy as small space as possible in a folded condition the hinged connections at 4, 5 between said members I, 2 and 2, 3, respectively, will have to be made very compact.
This can be accomplished in several different ways, the general ideas of two of said methods being illustrated diagrammatically in Figs. 4 and 5. In these figures the threads 6 and I represent the wefts in a woven fabric and run transversely of each screen member I, 2, 3, so that each longitudinal edge of said screen members has a series of loops like those formed by the threads 6 and I. 5 responding to loops 6, I can not be made in the In Figs. 2 to 5, inclusive, the longitudinal threads of the screen member are not shown.
According to Fig. 4 a thread, or light rod, 8 is inserted through the loops 6, I of two adjacent screen members, thus coupling their longitudinal edges together in 'a way to enable said screen members to turn about said rod 8 without bending or straightening the threads 6, I of members.
In Fig. 5 a rod 9 is inserted into the loops formed by the threads 6 of one screen member, and another rod I0 is mounted in asimilar way in the loops I of another screen member. Said rods the screen 9 and II] are then interconnected by means of 'a' thread II wound aroundsaid rods, as shown in the drawing. .It should be obvious. that also in this case the two screen members are able to assume different relative angular positions without bending or straightening any threads.
.In theembodiment according toFig. 3 another method of connecting the screen members .is illustrated. The threads I of one screen member are inserted into the .loops'formed by theflthreads 6 of another screen member and through the, projecting loops of the threads I therod 8 is inserted.
, It should be evident that, in this case, in addition to the hinge action obtained the coaction between the threads and the rod will cause also a certain limitation of the turning movement of the screen members in the direction of increasing a the angle between them. In some cases this limitating action is of a certain value.
At the free edge of the firstand last screen members of a screen a rod I2 can also be inserted in the loops of threads I, as shown in Fig. 2. Said. rod I2 may be provided with bent portions I241.
I5 and I6 at the corner edge IT. This can be accomplished in several different ways, one method,
being indicated in Figs. 6 to 9, inclusive.
The parts, or pieces, I5 and I B are cut as shown in Figs. 6 and '7, respectively, and assembled as shown in Figs. 8 and 9. The connection proper, at H, can be made in a similar way as the connection between the screen members I, 2, 3 as shown in Figs. 3, 4, or 5. In case the loopsicornormal process of manufacturing the screen netting, they can be plaited into the screen material afterwards.
However, it is not necessary to use such loops, since any other means capable of acting as a hinge without breaking the threads of the netting material can be secured to the edges to be connected. Since screens of this type used to be mounted within the frame or within another cover of a suitable structure it is generally desirable to keep the dimensions of the contracted screen as small as possible, and this should be borne in mind When selecting the hinge means. Of course, also in the case of Figs. 3 to 5, inclusive, the loops could form parts of a separate edge cover or edge lining instead of being parts of the screen material proper and, furthermore, it should be obvious that the dimension of the loops in the direction of length of the screen member is a matter of choice. In some cases the rods may be dispensed with, the loops of two adjacent screen members then engaging each other directly.
It is to be understood that the embodiments described above are intended as exemplifications only and, therefore, they must not in any respect be regarded as limitations of the scope of my invention. The fact is, that several modifications can be made without departing from the spirit of the invention.
What I claim is:
1. A window screen comprising a number of substantiallyslat-shaped screen members connected in series to form -a screen part, hinge means interconnecting adjacent screen members, the ends of the screen members being cut obliquely alternately in one direction and the other direction, of two screen parts being connected together with said obliquely cut ends complementing each other and forming an angle between said parts whereby the screen is foldable like an accordion.
2. A foldable window screen for covering openings in planes at an angle to each other comprising a plurality of slat-like screen members,
hinge means connecting adjacent longitudinal edges of the slat-like screen members for one opening together in accordion fashion, hinge means connecting adjacent longitudinal edges of the slat-like screen members for the other opening together in accordion fashion, the ends of the screen members for one opening being oblique to the longitudinal edges alternately in one direction and the other direction, the ends of the screen member for the other opening being similarly oblique, and the oblique ends of the screen members for'one opening being connected to the oblique ends of the screen member of the other opening.
3. A foldable window screen for covering a rectangular and two triangular openings formed by opening a swinging window, comprising a set of slat-like screen members in edge to edge relation for the rectangular opening, hinge means connecting adjacent longitudinal edges of said slat members together in accordion fashion, the ends of each slat-like screen member being oblique to the longitudinal edges thereof to form trapezoidal members, second and third sets of slatlike screen members for the triangular openings, means joining the adjacent longitudinal edges of the slat-like members for the second set together and for the third set together, the ends of the slat-like members of the second and third sets which are adjacent the ends of the slat-like members of the rectangular opening being oblique to correspond to and complement the oblique ends of the slat-like members for the rectangular opening, and the oblique ends of the slat-like members for the rectangular opening being connected to the adjacent oblique ends of the slatlike members for the triangular openings whereby the screen will open and close with the window in accordion fashion.
4. A window screen comprising a plurality of substantially slat-like screen members in edge to edge relation, loops projecting from adjacent edges, theloops of one member severally projecting through the loops of an adjacent member, and means extending through the loops of said one member to prevent removal of the loops of said one member from the loops of the other member.
