United States Patent 3,006,268 WINDOW VENTILATOR Paul F. Du Bois III, 702 Summit Ave., Westfield, NJ. Filed Jan. 7, 1959, Ser. No. 785,363 3 Claims. (Cl. 9899.4)

This invention comprises a novel and useful window ventilator and more particularly relates to a window ventilator which is readily adjustable to difierent size windows.

A main object of this invention is to provide a window ventilator which may be adjusted to fit various size windows.

Another object of this invention is to provide a window ventilator which may be positioned within the lower portion of the channel in which the lower sash of the window is slidingly received.

A further object of this invention is to provide a window ventilator, in accordance with the preceding objects, which may be pivotally connected to the sides of a window frame so that the window opening may be closed by merely pivoting the ventilator in its brackets, thereby not requiring the removal of the window ventilator before the opening can be completely closed.

A still further object of this invention is to provide a window ventilator of the extendable type whose overlapping sections are slidingly mounted upon one another in a manner which will enable the ventilator to be readily adjustable in length.

A still further object of this invention is to provide a window ventilator which may, if desired, be mounted on the inside surface of the window frame so that the window may be closed without removing the ventilator.

A further object of this invention in accordance with the preceding objects, is to provide an adjustable window ventilator whose overlapping panels are made of a corrugated translucent material thereby allowing more light to enter the room and insuring a lesser amount of transverse motion of the overlapping panels in respect to each her. a a a A still further object of this invention, in accordance with the preceding objects, is to provide an adjustable window ventilator which may have colored translucent extensible panels so as to add color to the light passing therethrough.

Yet a further object of this invention, in accordance with the preceding objects, is to provide an adjustable window ventilator which will lend itself to conventional forms of mass production and one which will be inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a view in perspective of the invention shown mounted in the lower portion of a conventional form of window opening;

FIGURE 2 is an enlarged transverse vertical sectional View of the invention taken substantially upon the plane indicated by the section line 22 of FIGURE 1, parts being broken away;

FIGURE 3 is an enlarged longitudinal horizontal sectional view of the invention taken substantially upon the plane indicated by the section line 33 of FIGURE 1;

FIGURE 4 is an exploded view of the invention in perspective showing the manner in which the various parts of the window ventilator are assembled;

FIGURE 5 is a perspective view of one of the clips 3,006,268 Patented Oct. 31, 1961 used to mount and retain the two ventilator panels in sliding relation to each other; and

FIGURE 6 is an enlarged horizontal sectional view of the invention like that of FIGURE 3, but showing a modified form of end brackets with which a different method is used to mount the ventilator to a window opening, parts being broken away.

Referring now more specifically to the drawings the numeral 10 generally designates the window ventilator comprising the present invention which consists of two overlapping corrugated translucent panels 12 and 14 which are secured within a window opening 16 by means of end brackets 18 and 20.

Referring now to FIGURES 3 and 4, it can be seen that the end brackets 18 and 20 are generally right triangular in shape with the side between the acute angles thereof being inclined upwardly and inwardly from the window opening 16. Channel mounting members 22 and 24 comprising means for mounting the panels 12 and 14 and the end brackets 18 and 20 within the opening 16 are each constructed of resilient material having side flanges 23 and 25 which are normally biased apart so as to be frictionally received and retained in the tracks or channels 26, 28 respectively of the lower window sash 30 and serve to support the ventilator as now set forth.

Formed in each bracket 18 and 20 at the lower ends thereof is an aperture 32, and formed in the upper portion thereof is an arcuate slot 34 which lies upon a segment of a circle having aperture 32 as its center point.

Formed in each of the channel pieces 22 and 24 is a lower aperture 36 and an upper aperture 38, the aperture 32 and the slot 34 being registerable respectively therewith. Inserted and secured through aligned apertures 32 and 36 are suitable fasteners such as rivets 40 which pivotally mount each of the end brackets 18 and 20 to channel pieces 22 and 24 respectively. Passed through aligned apertures 38 and the slots 34 and secured thereto by means of threaded wing nuts 42 are threaded bolts 44. It can readily be seen that the end brackets are in this manner pivotally mounted upon rivets 40, and that their pivoting movement is limited by the ends of the arcuate slots 34 formed therein.

Formed on each of the inclined sides of the end brackets 18 and 20 are inturned flanges 46 which each have at least one bore 48 formed therethrough. The corrugated panels 12 and 14 are supported by the flanges 48 and are secured thereto at the outer ends by means of suitable fasteners and corresponding holes in the panels (not shown.

The panels 12 and 14 lie with their inner ends in overlying relaticn and with their corrugations nested as best seen in FIGURE 1, and are secured to each other in sliding relation by means of clips generally referred to V by reference numeral 50.

As can best be seen in FIGURE 5 of the drawings, the clips 50 each comprise a generally U-shaped member having two U-shaped end portions 52, whose arms define aligned slots or openings 53 of identical width therebetween, and a U-shaped mid-portion 54 whose arms define a slot or opening 55 parallel to and lying betwen the last mentioned openings 53 but of approximately twice their width. The two aligned openings 53 of each clip 50 receive therein a horizontal edge of one of the panels which is secured therein by means of fasteners (not shown) secured through aligned apertures 56 formed in the arms of each of the end portions 53 and corresponding holes in the panels (not shown). The corresponding edge of the other panel is slidingly received in the opening 55. Since the panels are of corrugated material, it is readily apparent 3 that any appreciable transverse motion of the two panels in respect to each other is vitrually eliminated.

Referring now to FIGURE 6 of the drawing in particular, the numeral 58 generally designates a modified form of the brackets which include an outtumed flange 59 formed on the vertical outer edges thereof which is adapted to be secured to the inner face of the window opening 16 by means of suitable fasteners 61 so as to enable the lower sash of the window to be completely lowered to a closed position without having to first remove the window ventilator.

'It is to'be noted that, although the corrugated ventilator panels have been shown in the drawings described herein to be constructed of a translucent material, this is the preferred material, and that any suitable material may be employed in the manufacture of the panels.

Further, since the preferred construction of the ventilator panels is of a material usually having resilient properties, it is to be understood that any suitable means maybe used to fasten the clips 50 to the panels. ceivably apertures 56 could be replaced by indentations which would, when the edge of the panels are forced into the openings 53 defined by the arms of the clips,

retain the clips upon the panels as desired.

It should be especially noted that the clips Edwill be effective to retain the panels in fixed aligned and adjusted relation even if the corrugations were to be omitted.

In operation, the channel pieces 22 and 24 are placed in window channel 26 and 28 respectively and the end brackets 18 and 20 are attached thereto. The extensible ventilator panels may then be adjusted in length and secured to the flanges 46. End brackets 18 and '28 may then be pivoted about the rivets 49 to a desired position.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be restored to, falling within the scope of the invention as claimed.
