(Cl. 1GO-23) 11 Claims.

Ivry Invention relates to improvements in screen holders and particularly to holders for roller screens of the flexible type for windows.

The object of my invention is to yprovide a holder for securing the edge portions of a flexible screen which will not break orv injure the fabric of which the screen is formed.

A further object is to provide casings, adapted to be secured upon the vertical members of a window frame, for holding rotatable locking bars, and provide said bars with longitudinal channels forming runways for the edge portions of the screen. Said bars being adapted for rotation within the casings to radial positions of said channels for bending, or deiiecting, the edge portions of the screen over rounded surfaces of the casings suiiciently for holding the screen in `place without tightly clamping the fabric of the screen.

A further object is to construct the casings so that the bearings for the ends of the roller may be mounted upon the casings.v

A further object is to provide a novel cover for the roller and the screen having detachable parts making the roller accessible.

A further object is to provide novel means for readily operating the screen and for holding it in the raised and lowered positions.

A further object is to construct the casings and parts so that they may be formed of molded plastic material adapted for holding a screen formed of like material.

These together with various other novel features of construction and arrangement of the parts, which will be more fully hereinafter described and claimed, constitute my invention.

Referring to the accompanying drawings:

Fig. 1 is a horizontal lsectional view, as on line II, Fig, 2, showing a screen and holder mounted upon a window frame, embodying my invention.

Fig. 2 is a View in elevation of Fig. 1, showing a portion of a window frame and the screen holder in section.

Fig. 3 is a vertical section as on line 3 3, Fig. 2, showing one of the side casings detached from the window frame.

Fig. 4 is a vertical section as on line 4-4, Fig. 2, showing the locking bar detached from the casing, which latter is shown in dot and dash lines, and showing the screen in the raised position.

Fig. 5 is a vertical section on line 5'-5, Fig. 2, showing the casing detached and the locking bar-removed.`

Fig, 6 is a horizontal section on line Iig-4i,-v

Fig. 2.

Fig. '7 is a perspective View showing a portion of the screen.

In the drawings, in which like reerence'characters refer to like parts, I0 represents a window lrame comprising a Asill I2, side frame members i3 and I4. A sash 'I5 is shown in the raisedl position in Fig. 2.

My novel screen structure comprises side casings Il and I8, adapted to be' secured to the frame members I3 and I4. The casings IT and I8 are of unit construction adapted to be formed of plastic material.

The opposite casings I'I 'and lI3 are provided with bearings I9 and 23, upon which a spring roller 22 is mounted. The roller 22 isv provided withrv a single 'locking pawl, or dog, 23, shown in dotted lines in Fig, 2, adapted for holding the roller against the action of a spring, not shown, in the usual manner. Upon the roller is mounted a exible screen 25, preferably formed of plastic material. The roller 22 is.V shown positioned upon the inner side of the` window frame and adjacent to vthe vertical center of the latter, so as to cover the opening when the sash I5 is raised, as shown in Fig. 2.

A box like cover 26 is provided for encasing the roller 22. Said cover extends between the casings I1 and I8, to which the ends of the cover are detachably secured by screws 21 and 28. The cover 26 comprises a top member '.29 a back member`3, which extends downwardly between the roller and the sash, and a separable front member forming a valance 3| covering the inner face of the roller. The lvalance 3I may be detached by removing the screws.28 thus' making the roller accessible for mounting and removing it from the bearings I9 and 20.

The casings I1 and I8 comprise

side walls

33 and 34 which form facing surfaces adapted to be secured to the framelmembers I3 and I4 by screws 35. Said

walls

33 and 34 extend upwardly and form heads 31 andy 38 upon which the bearings I9 and 20 are located. The cas# ings I'I and I8 are provided with flanges 4I) projecting inwardly from

said walls

33 and 34 and form supports for the ends of the cover 26.

Body portions

42 and 43 are formed upon

said walls

33 and 34 and are provided with

cylindrical bores

45 and 46, in' which are mount` ed for rotation locking bars 41 and 48, respectively.

Each of the body portions 42an`d 43 extends from a' point immediately below the head carrying the roller to an enlarged base 50 adapted to rest upon the sill I2. Each of the

body portions

42 and 43 has a longitudinal slot 52 defined by

edge walls

53 and 54. Said

walls

53 and 54 are adapted for retaining the bars 41 and 48 mounted loosely within the bores of the casings. Said bars 41 and 48 extend from adjacent to the top of thedbody

portions

42 and 43 to the bases 50, upon which latter said bars are supported. Said

edge walls

53 and 54 are spaced apart sufliciently to permit the edge portion of the screen to freely enter the bores of the casings and move freely within said slots. Each base 50 is provided with a vertical slot 56 through which the lower end of the screen may pass to the line of the sill I2.

Said bars 41 and 48 are each :provided with a longitudinal channel 58 adapted to be occupied by the edge .portion of the screen. Said channels form free runways for the screen. Each bar is formed with a rounded longitudinal edge surface 59, adapted for engaging the screen when the bar is rotated within thebore of the casing.

Secured upon the lower ends of the bars 41 and 48 are radially extending handles 60 and SI adapted for rotating said bars to the position shown at the right hand end of Figs. 1 and 2, in which the screen is free for vertical movement, or said bars may be rotated to the position shown at the left hand end of Figs. 1 and 2, in which the edge Iportion of the screen is shown secured between the rounded edge surface 59 of the bar and the inner surface of the bore of the casing, with said edge portion of the screen deflected around the edge wall 54 of the casing to an angle, relatively to the main portion of the screen, which is suilicient to hold the screen without injuring the fabric of the latter.

A rigid strip 63 is secured upon the lower end of the screen 25 and extends the full width of the latter.. 'Ihe ends of said strip4 83 enter the bores of the casing I1 and VI8 and also enter the channels 58 formed in the bars 41 and 48.

A finger grip 65 is secured to said strip 63 and is positioned upon the latter so as to permit the handles 68 and 6I to swing over the finger grip 65 when the screen is in the lowered position adjacent to the sill I2. The nger grip 65 is provided with an enlarged bead 65 adapted for holding the handles 60 and 6I in the locked position of the bars 41 and 48, relatively to the screen, as shown at the left hand end of Figs. 1 and 2 and in Fig. 6.

The lower ends of the bars 41 and 48 have reduced end portions which are semicircular in cross section, as shown in Fig. 6, so that the bars will not bend the ends of the strip 63 when the bars impinge the edge portions of the screen.

As shown in Fig. 5, the lower ends of the casings I1 and I8 are each provided with a projection 61, having an off-set vertical facing surface 68, forming a recess 69 and a shoulder 10. When the handles 60 and 6I are in the locked positions, the ends of the strip 63 of the screen are forced into said recesses 69, below the shoulders and retained against said facing surfaces 68 by the cam surfaces 12 formed upon the reduced lower ends of the bars 41 and 48, as shown in Fig. 6. By this arrangement the lower end of the screen is firmly'heldrelatively to the casings without bending the ends of the rigid strip 63 of the screen.

The casings v I1 and I8 are provided with notches 14, which form openings located above the bases 50, which openings permit the handles and 6I to swing to the unlocked positions of the locking bars 41 and 48, as shown in Fig. 2.

When the screen is in the raised position, as shown in Fig. 4, the finger grip engages a stop 15, formed upon the valance 3l. Said stop 15 limits the upward movement of the screen. The finger grip 65 and the stop 15 are positioned for engagement before the rigid strip B3 of the screen passes above the upper ends of the locking bars 41 and 48, thus retaining the screen in alignment with the channels or runways 58 of the locking bars, ready at all time to be lowered to the bottom of the casings I1 and I8.

Various changes in the construction and arrangement of the parts may be made Without departing from my invention.
