Claims. (Cl. 20-62) This invention relates to window construction, -and moreparticularly has regard to an improved, novel construction for a window of the jalousie type.

Windows of the type described above are finding increasing favor among home owners by reason of their desirable characteristic of facilitating uniform ventilation, and controllingthe inflow of light and air so that they-enter the room at a prescribed angle. Thus, a jalousiewindow has characteristics similar to those of a Venetianblind. At the. same time, however, vthe jalousie window also has a sturdiness and rigidity not found in Venetian blinds or shutters, and more importantly, can be used as a substitute for a window, by reason of the adaptability of the jalousie for being closed tightly in a manner to effectively prevent the flow of air into'the room from the outside.

The main object of the present invention is to provide an improved window of the jalousie type, characterized by the novel manner in which the slats can be adjusted to selected positions, and characterized further by the case and speed with which the slats can be locked in the selected position to which they are tiltably adjusted.A

Another object is to incorporate inthe window operator means a vnovelty designed latching and latch release mechanism, so designed that on adjustment of the slats to a selected position of tiltable adjustment, the slats will automatically lock in the selected position and-can be unlockedA responsive merely to depression ofa conveniently located button.

Another object is to provide,V in a jalousie window, a slat support bracket having a novel, improved construction that Will facilitate manufacture thereof at low cost, and that will be particularly designed forpivotally mounting the slats and for connecting the slats to an. operating A still further object is Yto provide a latching and latch release mechanism so arranged that the slats will lbe automatically opened to selected positions of tiltable adjustment upon actuation of a conveniently located button.

Another object is to provide manually controlled means independent of the latch releasemechanism for swinging the slats to selective partially-closed and fully-closed positions.

Another object is to provide a jointed'handle for clos-- ing the slats, with a portion of the handle rotatable toa position adjacent the window.

Still another object is to provide a jalousie window having slats with beveledjedges so that the slats assume a flat or coplanar position when juxtaposed in closed position.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and Vacocmpanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 19 is a fragmentary sectional view showing a further modification of the invention.

Referring to the drawings in detail, a jalousie window 10 formed according to the present invention is mounted in a window opening provided in a wall W. The jalousie window may be formed yof extruded aluminum, or any other suitable material, and in the illustrated example includes a rectangular frame 11 fixedly engaged in any suitable manner in the window opening, and formed with a horizontally extending sill 12, upwardly extending side jarnbs 14, 16 rigid with and extending upwardly from ,opposite ends of the sill, and a header 18 extending horiformed of rubber or the like and which has a cross-sec-k tional shape mating with that of the groove.

The header 18, as will be understood, is of a crosssectional shape opposite from but otherwise identical to that of the sill.

The side jambs 14, l16 are of opposite but identical cross-sectional formation, and are in the general shape of inwardly facing, confronting channels, thus defining longitudinal recesses in the respective side jambs facing so thatV the description of one will sufce for both.

inwardly, of the window opening to constitute cavities in which the window operating and latching mechanisms are recessed so as to be ordinarily concealed from view.

In any event, the side jambs 14, 16 include inner side walls '30, 32, respectively, coplanar with the depending wall 22 of the sill. In engagement with the sides of the window opening are web or body wall portions 34 vof the Side jarnbs, integral with'the walls 30, 32. Integrally formed upon the web portions are outer side walls 38, these being coplanar with the outer wall 24 of the sill. Projecting outwardly from and integralwith the walls 38 are seal strip support flanges 42 with the sealing strip 28 being of endless formation and being continued within dovetail grooves 43 provided in said flanges 42.

-llxtending longitudinally within the channeled side jambs are elongated, straight, at, wide operating or connector bars 44 disposed within the channels of the Side jambs 14, 16, respectively. Pivotally connected to the operating bars at locations uniformly spaced longitudinally of the respective operating bars, are end brackets 46 pivotally attached to the bars 44. ySupported by and extending between the end brackets are glass slats 52.

Referring to Figs. and 8, each bracket 46 .is of onepiece formation, being cut and shaped from a single blank of sheet metal material. The brackets 46 at opposite ends of the-slats areof opposite vbut identical formation Each bracket includes a supporting lever arm 45 which is of arcuate formation, having a short outer end 47 offset from the body of the arm. In end 47 is an opening 54.

The leverarm 45 is provided with an outwardly struck opening 79 which forms a tubingand is adapted to receive a complementary opening 28a formed in the sealing strip 2S, within the anges 42. Y

lntegrally formed upon the arm 4S of each bracket is a laterally inwardly projecting, elongated end ange S6 spaced from lips 58 and 58a, the lips being integrally connected to a web :39 extending therebetween. `Lip 589 is interrupted intermediate its ends by a recess 6t1tat the location of the arm 45. Further, lip`58e at its forward end projects beyond the corresponding end of the flange 56, and the projecting part of the lip 58a has a dependingextension 62. An inwardly extendingdimple or knob 61 is formed on extension 62. An inwardly extending knob 63 is formed adjacent one end of flange 56. These knobs together enter recesses 52e o n opposite sides of a slat S2 while the oiset extension 62 bears against the inner or under surfaceof the associated slat 52. The

slat is further engagedrmly by an inwardly-extending projection 65 on the ciset end 66 of lip 58 and opposed Vprojection 67 on ange 56. Thus, the slat is clamped betwen the flange 56 and lip extensions 62 and 66. A hole 69 is provided in flange 56 midway its ends as shown in Figs. 4 and 5 in which a screw 77 vcan be threaded to vpass through van aligned hole 57 in the slat to prevent the slat from accidental disengagement with respect to the bracket. Web 59 has obliquely cut corners 71, 73 which Vconform with the slant of beveled SideA edges'53 and 55 ofthe slat. I Y y ,y

Thus, each slat52 which is' of flat wide formationis Yengaged'in two bracketsl 46 at 'opposite 'ends oftheV slat. .In jFigs. 6 and 7 is "shown aypreferred constructionof'th'e slats. VOpposite lateral edges 53' and 55 ofthe slat are beveled and inclined in the same direction. Centrally located holes 57 are provided toreceive screws 77 for attaching the slat to ythe bracket. Additionally there are provided recesses 52a formed inopposite faces of the slat and spaced from holes 57 for receiving infstruck indentations 61, 63, 65, 67 in the brackets 46. By reason of the -beveled side edges ofthe slats they are enabled to be positioned in hat coplanar alignment, as clearly shown in Fig. ,2, with adjacent lateral edges of the slats i juxtaposed to eachother for forming an elective weathertights'at It is important to note that the sealing strip 28 is located so that the ends of the slats will be brought to bear firmly against the upwardly projecting ridges or ribs when the slats are in the fully closed position. The beveled upper side edgeof the top slat and the beveled lower side edge of the bottom slat in window 10 will abut the sealing strip portions mounted in the sill and header respectively, So that the window is effectively sealed all around. The width of the sealing strips should be greater than the thickness of the slats in their aligned closed copianar position so that a continuous full seal will be formed between the closed slats and the strips.

it will be seen that each end bracket includes supporting lever arm 45, one end of which is integral with a channeled portion receiving the adjacent end of a slat, said channeled portion being extended at right angles to the arrn to which it is integrally connected, and arranged parallel to the offset arm section 47 which section is connected to an associated bar 44 by means of a rivet or pivot pin 7S extending through hole 54. l

The several brackets are pivotally mounted by pivot pins 68 anchored in outwardly'struck tubular openings 79 1n the webs59. The pins 68 are disposed upon their assoclat'ed side jambs in integrally spaced relationto the assoclated connecting bar 44. The pivot pins 68 are disposedY at the locations of and extend through the side portionsv of the sealfng strip 23 and throughthe anges 42 as will be readily seen from Figs. 2, 4 and 5A. The axes of the pivotal connections 68 pass through the channeled body portions of the brackets, that is, said axes are disiposed substantially in the planes of the slats 52, extending longitudinally of an` medially between opposite sides of the slats.

The latching and latch release mechanism, as best shown in Figs. 10-12, includes an angle bracket plate 70 having an upper side 72 in which is formed a closed slot 74. rlfhe side 72 carries a U- shaped bracket member 76 having aligned'rectangular openings 78, 80 in the legs thereof through which is slidable a rectangular pusher bar 82. An operating knob 84 is provided on bar 82. A coil spring 86 is sleeved on bar 82 between a pin 88 passing through bar 182 and the adjacent end leg of bracket 76. Bracket member 76 has its bight 76a welded to side 72 of the bracket plate 70. The inner end of bar 82 is-formed with a tooth 89. A pin 91 projects from bar S2 between the legs of member 76 and serves as a stop element preventing removal of thebar from member 76 as springi86 expands.

A ratchet bar 90 best shown in Fig. 9 coacts with bracket 70. This bar has a plurality of teeth 94 formed in one edge. A hole 96 near one rounded end 97 serves to receive a pin 98 by which the bar is pivotally mounted on arm 99 carried by bar 44 'as shown in Figs. 3, 11, and 12. A recess100 in bar 90 near the narrow upper end of the bar receives one end of a coil spring 102 'which is received at its other end ina hole 104 in bar the toothed end of bar 82.

The operating bar 44 is normally urged downwardly by a tensioned spring 106 best shownin Figs.' 2 ,Q3 and 4. This -spring is'secured atv one Vend by 'an anchoring p'in108 near thebottom of wall 38 and at its other end by'a hook 11.0v secured to bar 44. Thedownward pull on bar 44 causes the lower at edge of one of the teeth 94 of bar 90 to engage on the inner end edge wall of slot 74 adjacent the protruding tooth 89 of bar 82, as shown in Fig. 11. Spring 102 urges bar 90 toward bar 44 -so that the innery undercut side of one tooth 94 is pressed down firmly on the upper surface of the horizontal side 72 of the bracket 70. The vertical side 112 of the bracket is secured byrscrews 114 passing through holes 116 in side 112 and threaded in holes in wall 34 of the jamb 14.

then released, bar 90 will move toward edge 74a of the slot under bias of spring 102 until tooth 89 is retracted from the engaged tooth 94 whereupon the released tooth 94 will engage at edge 74a of the slot in a position similar to that shown in Fig. 11. During this downward movement of bars 90 and 44, all the slats 52 will pivot on pins 68 to a partially open position. If knob 84 is pressed a number of times in succession the slats will be caused to open more and more a step at a time kuntil the fully open-position, as shown in Fig. 3, is attained.

In order to close the slats, there is provided a cord or cable 120 preferably formed` of twisted steel wire, as

'best shown in Figs. l, 2 and 3. This cable is connected at one end to the top of bar 44 and passes over pulleys or rollers 122 and 124 rotatably mounted on wall 34 of jamb 14. `Pulley 124is disposed in a slot 126 in the front wall 30 of jamb 14 so that the cable extends through the slot. A lead or iron weight 127 is secured to' the cable outside of the jamb. pulling ring 130 issecured to the weight by eyebolt 132. I

To close the slats, it is only necessary to pull downward manually upon the cable 120 so that the bar 44 will be raised to tilt the slats from their open position shown in Fig. 3 to the-closed position shown in Figs. l and 2, or to any intermediate position between fully open and fully closed positions. The selected partially closed position of the slats will be maintained by engagement of one of the intermediate teeth 94 with bracket 70.` As the bar 44 in jamb 14 is pulled upwardly the force is transmitted via the lever'arms 4S and slats 52 to the corresponding bar 44 in jamb 16. The slats will remain in the selected partially closed and in the fully closed position by the operation of the latch mechanism provided by bracket 70V and the ratchet Vbar 90. To open the slats fully or partially from the fully closed position or any partially closed position,l the knob 84 must be manually pushed one or more times to operate the latch release mechanism associated with bracket 70.

Instead of a cord or cable 120 for operating the bar 44, there may be provided a metal chain. As a still further alternative for selectively closing the slats, there may be provided a handle operated linkage 140 as best shown in Figs. 13-17. This linkage includes a bell crank lever 142 having an arm 143 and an enlarged center section 145 provided with a hole 146 just beyond arm 143,!which hole serves to receive a pin 148 for pivotally mounting the lever on wall 34. The center section 145 extends through a slot 147 in wall 3 0. A link 144 is pivotally connected at one end to the end of arm 143 by means of a pivot pin 141 and at the other end to bar 44 by means of an eyelet 150 struck-out from the bar 44, adjacent the bottom end thereof so that as the bar 44 moves downwardly under bias of spring 106, the bell crank lever 142 pivots downwardly within jamb 14. When the lever 142 is pivoted upwardlyvon pin 148, the bar 44 is raised to close the slats.

Attached to the other arm 154 of lever 142 is a lever handle 156. This lever handle has a forked end 160 pivotally attached to arm 154 by va pin 158. The Vfree end 162 of the handle is offset from thecentral longitudinal plane of the bell crank lever 142 by a bent section 164. This offset portion provides clearance for grasping the lever handle and applying a force to it. lt will be noted that the lever handle is pivotally attached to lever 142. This pivotal attachment is so arranged that the lever handle can be rotated angularly from the outwardly extending position shown inldotted llines in Fig.

6. 16 to an upwardly extending position adjacent to flange 30 as shown in full lines in Fig. 16. This permits the lever handle to bepivoted out of the way of curtains, drapes, or the like whichv may be placed adjacent to the window. The lever handle 156 is limited in angular rotation," with respect to the lever 142 at one end to a position of alignment with arm 154 of the lever, as shown in Figs. 13, 15 and 17, because of the angular corner 155 on arm 154. When the lever handle 156 is disposed in a downward position adjacent flange 30, as shown in Fig. 15 the slats are fully closed. When the lever handle is moved Vto an upward-position the slats are fully open as handle may be pivoted with respect to arm 154 shown in Figs. 14 and 16. In any partially open or closed position ofthe slats, the lever handle can also be disposed to a vertical position. It will be understood that whenever the slats are adjusted to open or closed positions, the position of the bell crank lever changes, necessitating a repositioning of the lever handle 156 with respect to the lever if it is desired to place the vlever handle in an out of the way position adjacent to the window.

v j There vtion, means wall 30'.

In Fig.l 178 the ratchet bar 90 is shown to be pivotally mounted to the operating bar 44' by a xed pin 98 which,

engages in hole96' of the rounded end 97 of the ratchet bar 90. A coil spring 102 is provided around pin 98 to urge the ratchet bar 90 functioning position.

It" is possible to fabricate the window structure with conventional fullylflat slats which overlap when in closed position. However, the beveled edge slats as disclosed herein are preferred because of the at coplanar innerv the window in the closed position.

and outer surfaces of Such a wholly dat arrangement of the slats has been found to be easier to clean and to keep clean, and pre-V sents a more attractive appearance. Also, there is an economy eiected in the amount of glass required to form the slats used in the window employing beveled edge slats because narrower slats canl be used.

has thus been provided, according to the invenwindow responsive to manual actuation of a knob controlled latch release mechanism. The opening of the slats being effected in steps from fully closed to fully open position. There has been further provided manual actuation means for closing theslats with the latch mechanism retaining the slats in selective partially closed positions.

In Fig. 19, the pusher bar 82 is shown to be engaged by hand lever 110 pivoted at 111 at the outer side of the In other respects this form of the invention is similar to the previous form and the corresponding parts are indicated with similar reference numerals with a prime added.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and 4desire to secure by United States Letters Patent is:
