FRANK MILAVEC ATTORNEYS LOUVRE Frank Milavec, 18911 Monterey Ave., Enclid, Ohio Filed Oct. 8, 1958, Sen. No. 766,132

7 Claims. (Cl. 189-63) This invention is particularly directed to a louvre structure which is useful in connection with residential housing, commercial and business establishments and it is adapted for attachment to metal screen structures having framing members of aluminum, steel or the like with a suitable fiy screen therebetween.

This invention relates to a louvre structure fonned with dihedral angled slats adapted for attachment to a screen and positioned generally outwardly therefrom to provide a sun shield for the building to which it is. attached.

In general in the prior art in the field of louvre structures there are a number of examples, such as:

U.S. Patent No. 2,355,847 U.S. Patent No. 2,397,458 U.S. Patent No. 1,596,776 U.S. Patent No. 8,679 U.S. Patent No. 2,555,626

However, a structure for simple attachment to a screen or the like has not been found, particularly one having a means for attaching the slats or louvre members in a frame.

This invention is directed to a peripheral framing member or side channel structure generally of E shape in cross section, with a wing attached to said E for attachment tothe trame of a screen. The slat extends be* tween the E shaped cross section framing member and is fitted in angled slots in two legs of the.E to holdthe dihedral angled slat between the oppositely disposed E- shaped frarning members.

In general this invention consists of a louvre structure comprising a multiplicity of dihedral angledslat members positioned between E shaped raming members having angled slots between the outer legs of the E. and having a narrow slot to position one side of the dihedral angle to hold the slat firmly in position.

An object of this invention is to provide a new and simplified louvre structure having a multiplicity of slats with a framing member incorporating an E shaped cross section with a wing or other means for attachmentto the framing structure. Two of the members of the E shaped peripheral framing member have angled slots therein to hold the dihedral angled slat therein.

A further object of this invention is to provide a new and simplified louvre structure with improved holding means for the slat.

To the accomplishment of the foregoing and related ends, said invention thon consists of the means herein after fully described and particularly pointed out in the claims; the following description setting forth in detail one approved means of carrying out the invention, such disclosed means, however, constituting but one of the various ways in which the principles of the invention may be used.

In the drawings:

Fig. 1 is a fragmentary elevation plan view of a corner of this louvre structure;

"lice Fig. 2 is a cross-sectional view of Fig. 1 along the line 22, showing the slats in cross section and the upper framing member;

Fig. 3 is a fragmentary cross-sectional view of Fig. 1

along the line 33, showing the cross section through one of the side framing members;

Fig. 4 is a fragmentary perspective view of a portion of the slat and the portion of the side framing member;

Fig. 5 is a perspective view of a portion ofa modifie slat having a rollededge;

Fig. 6 is a fragmentary perspective view of the framing member itself;

Figs. 7 to 10 inclusive are modifications of the framing member.

In general in connection with louvre structures, there are a great number of devices for holding a series of louvres or slats and these may be either curvedor straight with various types of side framing members. This invention is an improvement and provides for a simplified framing structure which holds the slat by difierent means, in that the slat is not in a single plane, either straight or curved, but forms a dihedral, and it has one leg of the dihedral extending for a greater length than the second leg. T he second leg is substantially vertical within the side framing member. This permits the slats to be positioned on the site or in the factory from extrusions and provides reduced shipping costs as well as case of handling. The slats fit within an E shaped side framing member having a wing or extrusion to attach it to a structure.

Fig. 1 is the fragmentary view of the entire louvre, and 10 shows one side framing member and 11 shows the top framing member with a plurality of louvres12 which are supported by the framing members 10 and 11. This invention is adapted to be fastened to a screen member shown generally at 13 which may be of any particul'ar cross section and has secured thereto a window screen element 14.

As seen in connection With Figs. 1, 2, 3 and 4 the slat 12 is a dihedral having a large planar portion 16 and a smaller planar portion 17. The large planar portion extends between two eut sections or formed sections 18 and 19 in the E shaped cross section side framing member. The vertical portion of the dihedral 17 extends in a slot indicated generally at 21). The shape of the extrusion is generally that of an E having a backing or vertical member 21, a lower leg 22 which is outwardly. of the screen section, a middle leg 23 and an inner leg 24. Between the leg 24 and leg 23 fits the vertical portion 17 of the louvre as seen in slot 21 The inner and middle leg portion may be formed in various shapes to form a wing portion shown generally at 2d.having an inner strip member 27 and an outer strip member 28. The slat 12 will be positioned into the side framing member and securely held in place againstany movement either longitudinally or vertically because of the vertical portion 17 riding in the groove 29 and because the notch' 19 prevents vertical displacement.

Fig. 2 shows a vertical cross-section of the horizontafllytherebetween. The lower section is that of a channel member with a return bend portion indicated at 35 forming et U or channel merhber as seen generally at 36 having one portion which is perpendicular to the general plane of the strip as seen at 37 and a portion parallel to the general plane of the strip as seen at 38. This forms a framing member for the top framing element,.

The slat 12 has its vertically ext:ndiiig. planar portion 17 fitted between the slats and securely held- In addition to this structure, the side framing elements are seen generally in connection with Figs. 7 through 10 in four variant forms.

Fig. shows an alternate view of a slat 40 having a vertical portion of the dihedral 41 and an angled portion 43. The dihedral is at an obtuse angle. l'he lower edge of the dihedral 44 has a rolled portion 45, and this may be formed by various techniques and strengthened to provide a sturdier structure against accidentalhlews or possible twisting under strong wind conditions. 4 It will be seen, of course, that the louvre of this invention, shown outwardly of a screen element, has utility for use with the windows et a house to shade the window but at the same time it*may be used in connection with attic louvres. Under some conditions'these louvres would be provided with thescreen outwardly and ivith one or more of the louvres positioned therein. In order to keep the rain off, -these louvres may be inverted from the cross-sectional view shown in Fig. 2 so that rain or the like will drip down and not get inside a house but at the same time insects, birds and animals could not use them for nesting purposes.

The cross-sections shown in the drawings in Figs. 7 through basically have the same general configuration, in that they basically comprise an E shaped member hav ing a Wing portion to secure it to the house, window, 'screen or the like, and though they may differ in the general method of fabrication, such as the -extrusion shown in Fig. 10, members riveted together in connection with Fig. 7, members which are rolled together as in Fig. 8 or a T member as seen in Fig. 9, they provide the same basic components. Because they difier slightly, difierent numerals will be used to define the parts of each of these side framing members.

Figs. 4 and 6 are substantially the same except that Fig. 4 has the obtuse dihedral slat shown in position in fiagmentary form.

Fig. 7 is formed of two members, the channel member generally being designated by the numeral 45 having one leg 46 forming the middle leg of the E, an outer leg forming another portion of the E at 47, each of which has a corresponding slot therein 48 and 49, and this channel member 45 is then riveted as at 50 to a backing member shown generally at 51 having a strip back to back with the back of the channel as at 52 to which it is riveted and a member perpendicular thereto as at 53, and a bend 54 around 180 as well as a fiat member substantially parallel thereto 53 forming the upper leg of the E as at 55.

Fig. 8 shows a further construction generally comprising a Z-shaped member 57 having an outer leg 58 with a slot therein 59, a center web section forming the backing member 60 and a further leg to the Z as at 61. The further leg is folded into an end member shown generally at 62 having one bend portion 63 bent around the leg of the Z and having a further bend portion 64 bent with a return bend portion at 65 into a channel member shown generally at 66 which encompasses the vertical portion of the slat. This is bent to form the middle section of the E of the channel as at 67 and there is a slot shown at 68 in the middle leg.

A further modification is shown in connection with Fig. 9. It comprises a combination of a T section and a channel. A first or outer leg of the channel 70 is fastened at 71 on the back of the channel 73 to the T section 72. The middle leg which is the opposite leg of the channel is seen at 76 and is closely spaced to the T shown at 74 providing an opening for the louvre. The wing or the opposite and of the T shown at 75 serves as a Wing for attachment to the screen. The slot in the flanges of the channel 70 and 76 are shown respectively at 78 and 77.

A further modification of the invention is shown in connection with Fig. 10 which would be an extrusion, the latter having the slots milled or cut therein. It generally consists of a winged channel, having a channel section designated generally at 80 with the first leg of the channel shown at 81, a backing for the channel as at 82, the opposite section of the channel as at 83 with a special angled strip shown at 84 forming a sharp acute angle with the backing section of the channel 83 into which the vertical slat may be positioned. The wing section of the channel is shown generally at 85 permitting attachment to a screen or other structure. Holes therefor are shown as at 86. The slots would be milled or out therein as shown at 87 and 88.

These combinations and variations of my invention provide various ways for making the side framing members and under some conditions one member might be preferred to another. In general, the basic idea is that a plurality of slats preformed may be positioned between the channel members which are simple fabricated structures, and then they are out to the respe tive angles and ready for assembly at a warehouse or shop. In this manner sections are provided which can be conveniently made on the site and reduces the cost.

Most of the work calls for a custom fabricated job and in this connection, it is diflcult to ship the items because of their bulk and light weight, at reasonable costs. However, by shipping disassembled or simple fabricated members to provide these louvres, the cost would be greatly reduced.

Although the present invention has been described in connection with a few preferred embodiments thereof, variations and modifications may be resorted to by those skilled in the art without departing from the principles of the invention. All of these variations and modificatiens are considered to be within the true spirit and scope of the present invention as disclosed in the foregoing description and defined by the appended claims.
