15 Claims.

. My invention relates to window shadesand has for an object to. provide a shade constructed of anumber of panels hinged together at their edges and simulating in appearance a Venetian 5 blind.

Another .object of the invention resides in providing certain of the panels with openings and.

other of the panels with deflectors shading said openings.

A still further object of the invention resides in constructing the shade from a sheet of flexible material folded transversely along spaced parallel lines to form plaits'hingedly connected together at their edges.

An object of the invention resides in arranging said openings and deflectors at certain of th edges of the plaits or panels.

Another'object of the invention resides in con structing said deflectors from the material of the shade separated therefrom in the formation of I the openings.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details oi construction hereinafter illustrated'and/or described.

In the drawings:

Fig. 1 is a perspective view of a window illustrating an embodiment of my invention applied thereto and disposed in extended position.

80 Fig. 2'is an elevational view of a portion of the structure shown in Fig. 1 and drawn to a larger scale.

Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 1 and drawn to a larger scale.

35 Fig. 4 is a view similar to Fig. 3 showing the shade collapsed.

Fig. 5 is a developed view of the blank from which the shade is constructed.

For the purpose of illustrating my invention,

I have shown in the drawings an ordinary double hung window which is indicated in its entirety by the reference character A. This window is constructed with a frame Ill having a'casingextending about the same and provided with 45 stops l2, l3, and, I4 between which the upper and lower sash l and I5 oi the window may slide. The window further includes a window sillv l1 which forms part of the frame Ill and which extends up against the lower sash l5.

My invention may be constructed from paper l or any other suitable flexible material which can be scored or otherwise constructed to provide panels hingedly, connected together at their edges orthe same may be constructed from-sep- 55 arate panels of any suitable .,material attached together at their edges by means of any suitable hinge construction. In the drawings I have shown the invention as constructed from a sheet of paper and the following description covers this form of the invention.

The blank from which my window shade is constructed is shown in detail in Fig. 5 and is indicated by the reference numeral Hi. This blank is scored at one end along spaced lines l9 and 2| and adjacent these lines is scored 10 along other lines 22 and 23. The shade is similarly scored at the other end along lines 24, 25, 26, and 21 which correspond to the scores l9, 2|, 22 and 23. Between the scores 23 and 25 the sheet is alternately scored along lines 28 and 23 ,15 which are equally spaced. By means of the va- 1 rious scores, the blank I8 is divided into panels 3|, 32, 33, and 34, at the upper end of the sheet with panels 35, 36, 31, and 38 at the lower end of the sheet-and into alternate panels 4| and 42 intermediate the panels 34 and 38. The lateral edges of the blank l8 are designated by the numerals 43 and 44 which form the ends of the various panels. 1

Intermediate the edges 43 and 44 of the blank I8 are arranged two rows of holes 45 and 45 which are situated along two vertical zones 41 and 48 of the shade. Adjoining-the edges 43 and 44 of the blank are arranged two other zones 5| and 52 which are similar to the zones 41 and 48. The scores 28 extend completely across-the sheet while the scores 29 are confined to the zones 41, 48, 5|, and 52.

In each of the panels 42 is formed a series of openings 53, 54, and 55 which are disposed ad- I jacent the scores 29. These openings are identical in the various panels and only those in the uppermost panel will be described in detail. The openings 53, 5,4," and 55, -"are, constructed by shearing the panel 42 along longitudinally extending lines 56, 51, and 58 which occupy the entire space between the zones 41, 48', 5|, and 52. The panel '42 is'further sheared along trans- ]verse lines 59 which extend up to the lines 28. By 'means of this construction extensions 5|, 52 and 53 'are formed on the panels 4| which project downwardly from the lower edges thereof and which are constructed of the'material removed from the panels 42 in the formation of the openings 53, 54, and 55. These extensions serve as deflectors as will be presently more fully described, and shade the openings .53, 54 and 55 formed in the panels 42. j For the purpose of supportingthe shade at the upper end thereof, the panels 3|, 32, and 33, 5

- beheld in'position by means of are employed-which are wrapped about a bar 64.- This bar may be constructed of paper, wood or any other suitable material and serves to stiifen the upper structure of the shade and provide a means for attaching the same to the window proper. The panels 3|, 32, and 33, are

preferably glued or otherwise secured to the said bar.- The bar 64 is attached to the header,

of the stop M by means of screws 65 which pass through said bar and the panels attached there- At the lowermost end of the shade is provided .another bar 66 constructed similar to the bar 64 and attached thereto by means of the panels 35,

36, and 31, the same as at the bar 64. This barserves as a weight for causing the shade to descend into extended position and in addition serves a purpose which will be presentlydescribedin detail.

When the shade is in extended position, the

panels thereof occupy inclined positions as shown in Figs. 1 and 3. It will be noted that the openings 53, 54, and 55 are arranged toward the window sashes l5 and I6 and likewise the deflectors 6|, 62, and 63inclined downwardly toward the window sashes in a manner to shade said openings. By means of this construction, light may be indirectly transmitted through the shade and at the same time air pu'sed through the shade for the purpose of ventilation.

The movement of the panels of-the shade into extended position is limited by means of two tapes 61 and 68 which are attached at their ends to the bars 64 and 66 and intermediate their ends to the edges of the various panels formed by the 35 scores 28. The tapes 61 and 68 are preferably constructed of a relatively thin paper, fabric, sized cloth or some other suitable material which will readily bend or fold. Said tapes may be secured to said panels by wire or fabric stitching or by 40 gluing the same thereto. In the drawings, I have shown wire staples 69 for securing the said tapes to the panels. When the shade is in extended position, the two tapes 61 and 68 are drawn tautas shown in Figs. land 3 and limit the further 45 extension of the panels. When the structure is collapsed, as shown in Fig. 4, the tapes are doubled back upon themselves to form folds H which occupy the position shown in Fig.4.

For the purpose of raising the shade two draw 50 cords 12 and 13 are utilized which are threaded through the various openings 45 and 46 in the panels of the shade, and also through two eyelets l4 and 15 attached to the bars 54 and 66. The cords are knotted at one end as indicated at I6 to 5 prevent the said cords from passing through the deflectors 6|, 62 and 63 form continuations or extensions of the panels 4| from which they issue and shade the openings 53, 54, and 55 in the ad- 0 joining panels. Due to the fact that the, scores 29 do not extend'across these deflectors, the said deflectors are integral with the panels from which they issue and when the structure is in either collapsed or extended position, lie in the plane of 75 said panels. Whenthe shadeisraised bymeans thereohand a deflector of the draw cords the parts assume the positions shown in Fig. 4, and the shade is entirely out of the way, giving a maximum amount of light through the window.

My invention is'advantageous in that. an extremely simple and practical construction is provided which may be used for the purpose of a from various kinds of materials. The-shade is simple in operation and is not apt to getout of order. By means of the particular opening and deflectors formed in the shade, it becomes unnecessary to adjust the panels thereof as is the case with Venetian blinds. When the shade is constructed of paper, the various panelsthereof may .be folded into an exceedingly compact form so as not to obstruct any appreciable area of the -window. Thedeflectors in addition to shading the openings, serve to deflectrain and prevent its v passage through the shade.

Changes in the speciflc form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:
