1 Claim.

This invention relates to a construction for a ventilator to be used in an opening such as that as is provided by a window.

It is in general the broad object of the present invention to provide a simple ventilator structure which can be installed in an opening as that provided by a window, to permit access of air and light and yet provide privacy.

A further object of the present invention is to provide a novel ventilator construction which enables the ventilator to be adjusted readily to accommodate openings of different widths.

A further object of the present invention is to provide a novel mounting for a ventilator slat in a support.

The invention includes other objects and features of advantage, some of which, together with the foregoing, will appear hereinafter wherein the present preferred form of ventilator construction embodying this invention is disclosed.

In the drawing accompanying and forming a I part hereof,

Figure 1 is a perspective view with portions of a window frame broken away to illustrate the ventilator blind construction embodying this invention.

Figure 2 is a fragmentary view of one end of the blind.

Figure 3 is a section taken along the line 3-3 in Figure 2.

Figure 4 is a section taken through an intermediate portion of the blind. Referring to the drawing, a window frame is generally indicated at 6 having a sash 1 movable therein. Mounted between the horizontal sill 8 of the window and the side frames is a ventilator generally indicated at 9 and embodying the present invention. The ventilator 9 includes a plurality of spaced vertical supports respectively indicated at ll, [2, l3 and M. A first plurality of slats 16 are extended between the first and second supports H and 13, while a second plurality of slats i! are mounted between the third and fourth supports, [2 and [4. In the embodiment disclosed, the respective slats are preferably provided by thin, flexible metal slats such as the typical aluminum slats now frequently utilized for Venetian blind manufacture, but flat wooden slats can also be utilized. Each slat is preferably curved on a radius about its transverse axis, each slat being suitably painted or otherwise of an acceptable color.

The respective plurality of slats l6 and I! are mounted in their respective supports in a parallel and spaced relation to one another and wherein each plurality of slats are successively suitably superimposed to provide a ventilator suitable for mounting in a window frame. When it is desired to provide a ventilator to fit a window of a given size, and without any feature of adjustment, it is only necessary to mount a single plurality of slats in a pair of the vertical supports, the particular mounting being further presently described. However, when it is desired to provide a ventilator which is adjustable to fit various openings, then the respective plurality of slats are mounted in such relation to one another that the respective and corresponding individual slats in the first plurality are slidable over the corresponding individual slat in the second plurality of slats .whereby the slats can be adjusted to provide a ventilator corresponding to the total length of the two plurality of slats, or else collapsed to the length of substantially only one of the individual plurality of slats. To accomplish this, it is, of course, necessary that the intermediate supports in each support pair, namely supports l2 and I3, be sofashioned that the slats of one plurality are slidable upon the slats in the other pluralities, as will presently appear.

To mount the respective slats in vertical supports H, 13 and i4, each vertical support is provided with an aperture generally indicated at 2|, and corresponding substantially to the shape of the slat in transverse section, but preferably hav ing a shape which is slightly different from that of the slat so that the slat is sli htly flexed in the aperture. Thus, with a curved slat, the aperture receiving the slat is of a curvature slightly different from that of the slat in transverse section. To retain the slats in place, the outer edges of each slat in each of the respective pluralities are notched as at 22 and 23. As appears in Figure 2, the end of each slat will stand slightly above the end of the aperture and so retain the end of the slat in engagement with one of the end vertical supports II and M; to facilitate this, each aperture 2! in an end support I! or M includes a portion 24 extending inwardly in the direction of the radius of curvature to maintain engagement of the

notches

22 and 23 with the vertical suppor In intermediate support i 2, that heretofore designated as the third support, projections 26 are provided, these extending outwardly along the radius from the lower edge of the aperture 2| to engage the notches in the lower slat of the slat pair and permit the outer slats to stand above the lower slat and so permit the two to slide while 3 the lower slat is retained in engagement with the intermediate support.

From the foregoing, we believe it will be apparent that we have provided a novel, simple and improved adjustable Ventilator construction and particularly a novel mounting for the slats comprising the ventilator in their supports. Instead of two pluralitiesmfislats, one canusethree or more, depending on the width to be accommodated.

We claim:

In a ventilator of the class described;.;a7first.pl1r: rality of thin flexible metal slats having transverse notches in each edge thereof adjacent eachend thereof, a first and a second suppprtengagedr with said slats at each end thereof and supporting said slats in a parallel spacedrelation;lay-seem ond plurality of thin flexible metal slats havingvtransverse notches in eachedge thereof adjacent each end of the-second plurality' of-"slats' andsupportingsaid slats in a parallel spaced--relation; each ofthe second and third su-pports beingaper 4 tured to pass slidably the slats of that plurality of slats other than that to which such support is secured, each of the first, second and fourth supports includin an upwardly extending narrow arcuate slot to receive and pass a slat, the lower edge of each slot being recessed to provide upstanding projections to engage the notchesin the ends of the slats" engageditlferewith,s-thetthitd support beingpositioned intermediate the first and second supports to provide support for one end of thesecond plurality of slats and to pass slidably the-.first-pluralitypfslats, said third support having an upwardly extending narrow arcuate slot, thezupperedge of'eachslot being recessed to provide"depending:projections to engage the notches in an'end of the second plurality of slats.
