4 Claims.

This invention lrelates to 'improvements in metal slat rolling doors.

Metal slat rolling doors to which the improvements in accordance with the'present invention are applied, are generally `Well known and comprise a plurality of horizontally disposed slats, in

most instances of'corrugated form, and such slats are provided with vsubstantially semi-cylindrical interengaging edge portions -to facilitate rolling ofthe door from'a closed'to an lopen position and vice versa.

It is a well recognized fact :that windows are desirable in all doorsparticularly when of relatively large dimensions as are mostmetal slat rolling doors. It is appreciated that it iscommon practice to provide doors of vrelatively large dimensions, such as those used on garages and the like with windows, but the use of windows heretofore hasbeen usually in connection with such sectional wooden doors which are lconstructed for hinging or vsliding movement.

Such forms of doors just referred to usually comprise relatively large sections and accordingly the provision of windows in the sections is a simple matter and would readily be suggestive from the long time use of windows in a single section door.

The provision of windows ina metal slat rolling door is'just vas-desiralole'as inany other 'form of door, but due to the construction of such metal slat doors the vprovision of windows-therein presents a problem in no way'suggestive'by the'use of windows in sectional woodendoors,

It is accordingly a--primaryfobject-'of -this invention vtoV provide a metal PSlat-rolling 'door lwith a-win`dow of suiiicient-dimensions to providefnecessa-ry admission of light-as ywell as'for observation from either side of the door.

A further object-ofthe linvention is to provid a multi-section window in a Lmetal fslat rolling door and wherein'the adjacent edges ofthesections have a pivotal movement corresponding with that of the slats of the door.

A vstill further object of Vthe vinvention is to provide novel clips for -removably'securing-transparent VWindow sections to lspaced 'fend portions of metal -slats in a vrolling door.

A :further vobject of 'the invention is 'to provide a'- transparent section in -a `hinged:metal-Slat door with provision of hav=weather-huglit n:ioint l'be- 2 tween the door and all four sides of the transparent section.

'Other vobjects and'a'dvantages ofthe invention Will become apparent in the course of :the following detailed description, taken yin connection with the accompanying drawings, wherein:

Referring now in detail -to :the drawings, ,'by usev of reference characters, B in Fig. ldesignates a Vportion of ra building, such :asa garage, fior the like, D. designatesa` metal lslat rolling door operatively supportedaina'dooropening inlztheiiuilding and W designates the improved window in the door.

The metal slat rolling door may be of usual construction and comprise a plurality of corrugated metal slats IIJ which extend horizontally and in parallel relation. The opposite edges of the slats are rolled in the provision of substantially semicylindrical portions which are in intertting relation to provide the pivotal connections I I between the successive slats.

An opening I2 (Fig. 2) is provided in the door as by cutting away portions of a desired number of the slats depending upon the size of windows desired or required.

While the window herein disclosed is of a height equal to the combined widths of three slats IIJ, it may be of a height equal to the combined widths of a lesser or greater number of slats, and the width of the Window may be of any dimensions desired. f l Y.

The window W comprises a plurality of transparent sections I3 and which lare preferablyl formed from plastic for the dual purpose of with- 4, slats I8, a diiferent form of clip is provided for removably securing the window sections I3 to the door slats IDS'.

Each clip, of which there is one at each end of each window section I3, comprises a portion I6a underlying an adjacent slat end and removably secured thereto by a pair of bolts I1. The clip further includes a wall portion |88 engageable by the adjacent end of the window section and a flange portion I9a underlying the window section and secured thereto by a pair of bolts 20.

' The slat ills*A above the upper `window section lI3 is provided with an apron'ZIa, andthe clip between the door andthe window sections.

standing shock or strain, as well as to facilitate the machining thereof tol proper shape.

VIhe window sections I3 are of substantial thickness as is indicated in Fig. 5, andthe adjacent edgesV of each` two sections have cooperating curved surfaces I4 which are concentric with the axes of the pivotalconnections II of the metal slats, whereby the'window sections will pivot with the metal slats during the rolling movement of the door, and providev a weather-tight'joint when the door is closed. 'y

Each slat I0 is provided with a window section I3," and in order to'removably secure the sections to the slats I8 adjacent Vopposite sides of the door opening I2,'a plurality of novel clip members I5 are providedg.

The clip vmembersIii each comprise a portion I6 shaped to substantially-conform with the corrugations in a` Slat I8, andsu'ch portion engages the interior of the slat and is removably secured thereto as by boltsI'I which extend through alined apertures in`the'portion I6 and the slat I0.

Therclip further includes a wall portion I8 engageable by an end lof arwindow section and a ange portion I9 projects from the wall portion I8 at right angles thereto. "j

The flange portions I9 provide seats for the inner faces of the window sections adjacent the opposite ends thereof, and the window sections I3 are removably secured tothe iiange portions I9 as by bolts 20 Yextended'through alined apertures therein. f

The liiange portions .further function to provide a weather-tight joint between the edges of the window and the doori'i` The lower edge of slatVA I8 above the uppermost window sectionis modified in form in' the provision of an apron 2I in overlapping relation to the upper edge portion 22 of'window section to provideaVweather-tight joint'without aiecting the proper rolling of the door.

f While thewindow sections have been disclosed in a corrugated metal slat rolling door, the invention'is not limited to such application since the window sections may be disposed in a metal slat rolling door wherein the slats are of at rather than corrugated form, as is disclosed in Figs. 2A, 3A, 5A and 8.

l As is' illustrated in these figures, the metal slats Illa are of at form and have pivotal connection at IIa. Since in this embodiment ofthe invention, the slats L.Illa are. of different form than While the window sections have been disclosed as removably disposed in metal slat doors wherein the slats in one embodiment are corrugated and in another embodiment are of ilat form, the essence of the invention is the provision of window Vsections in metal slat rolling doors wherein the bodies of the slats may be of any desired form.

From the above, it will be seen that each window section I3 is rigid with the transversely aligned slat sections to which it is secured, and that the adjacent edges of the window sections are provided with a pivotal connection coaxial with that of the corresponding slat sections whereby the window sectons'will partake of the same movements as the slat sections during rolling movement of the door and thus avoid any strain in the window sections.

While I have disclosed my invention inaccordance With certain fspecic embodiments thereof, such are to be considered as illustrative only, and not restrictive, the scope of the invention being defined in the sub-joined claims.

What we claim and desire to secure by U. S. Letters-Patent is:V
