Z'IA TTHEW .d' mrrfMA/v Patented July 27, '1943 OFFlCE 1 VENETIAN SLAT UNIT I Matthew John Witteman, Alhambra, Calif. Application July is, 1940, Serial No; 345,453
12 Claims;
My invention relates to "a Venetian slatjunit and more particularly to a unit comprising a series of Venetian slats, which maybe inserted in and removed from a window opening, as an entirety. An object ofthe invention is to provide a series of metal Venetian slats in such a unit, which may be easily flexed laterally; in order to insert the unit in place and to remove same. 1
Another object of the inventicnis to provide screen means on suchaunit, "whereby to ex clude flies and other insects, but to permitthe passage'therethrough of light and air; Other objects are to provide such a unit that is convenient in use, is of improved structure is easily installed and removed 'from'its 'operative'position, economical of manufacture, relative sim plicity' and general superiorityin seriIiceability.
The invention also coniprises'riovel details of construction and novel combinations and arrangements of parts, which will more fully'appear in the courseoi the following description. However, the drawing merely shows and the following description merely describes one embodiment'of the present invention,gwhich is given'by way of illustration or=exaimpleonly In the drawing, like reference characters desig; nate similar parts in the several views.
i Figure 1 is a broken,'vertical section of an em? bodiment of my invention, in its proper position for use i Figure 2 is a perspective view of the present Venetian slat unit, shown removed from-a win dow opening.
Figure-3 is an enlarged, broken section arts On'the line 3-3 of Figure 1, a Figure 4 is an end view of a modified'cQ; t tion of the unit.
convex and concave sides. Each slat is capable of being folded upon itself and when released assume its original shape; The unit may bearranged-with eitherside'up' in order that either the concave or the convex side of the slats is uppermost.
The ends of the slats are bent at an angle to provide flanges l6 that may be spot-welded against the inner face of the'channel end members it] and i2. Spot-welds are suggested at H.
In order to keep out flies and other insects, a screen [8 may be arranged across a. side of the unit. Ends [9 of the screen are Welded on the outer faces of the end members.
The modified construction'shown in Figures 4 and" 5 comprises a series of slats 28 having their ends Hand 22 bent around an'gularly disposed portions of wires 2; bent in'zigzagform, as best shown in Figure 4.1Th ends 24 and-25 of the wires 23 are bent substantially parallel but in opposite directions. a i e Each embodimentis constructed iriorder that it'may fit within the width of awindow frame. The sash is then lowered into' contact with the upper edge'of the unit. When in place, the unit provides an attractive-arrangement of Venetian slats that permitsthe entrance of light andair but keeps out flies and other insects.
Figure 5 is a broken, front' elevation-looking in the direction of the arrow A of Figure 4.
Referring more in detail'to thedrawin'ggthe reference numeral '1 designates a window sill upon which jambs 8 are mounted. A slidable' in the windowframe.
The embodiment shown-in'Figures i to 3 comprises channeled end members i l 0; and l2,- whose channels face each other. Flat spr'ings l 3 and I l are respectively mounted on the outer faces of the end members It! and 12, in order that-the unit may be firmly and resiliently held in place: between opposed channels 8 ofthe window frame. 7
Spanning the space between the members "lfii and I2 is a series of metalvenetian blind'slats I 5. The slats shown :comprise' a single thickness of material, which are continuously and gradually curved from: edge :to'edg, producing Sash 9 Inorder to insert the unitinto grooves in the Window jambs, such as shown at 26, the slats are flexed laterally, as shown by broken lines 21.
suggested at 28, whereby it may be inserted into the'grooves 26 in the windowjambs. A flexing line in a slat is Suggested at 29; The springs I3, M providea snug lit and prevent rattling of the unit when in place, The window screen [8 is flexed with the slats.
Theform shown in Figures 4 and-6 is inserted in the window frame by similar method, to wit, flexing thslats 20 laterally and permitting the resilience of the slats to snap-the end-wires 23 in position in the grooves in the jambs." a
"'In each form the-resilien'cof the slats tends to snap the unit'in the positionsldescribed. Removal of either form is performed by flexing the they are channel shapedpr' w form) fromthe gr'oovesZG;
with which they are placed in operative positions will be apparent from the foregoing'descriptioni While I 1 have illustrated; and described what I nowregard as the preferredembodimentof my It is believed that the simplicity of each of' the forms of the present invention-and the ease i r, a i dew nam a, s
