12 Claims. (Cl. 20-11) The invention relates to windows formed by the assembly of a plurality of window panels, sections or units to provide a sectional window.

The primary object of the invention is to provide a window unit structure which permits a high degree of flexibility in the formation of a sectional window. The window unit structure of my invention permits the formation of stationary, awning or hopper units, or any combination of such units, and further permits the selective assembly of any such units or combination thereof into either a straight or bowed window.

Other objects, advantages and results of the invention will be brought out by the following description, taken in conjunction with the accompanying drawings, in which:

i ig. l is a front elevation of a straight type sectional window made in accordance with my invention;

Fig. 2 is a perspective view of a bay type window assembled from the same window sections as used in the sectional window assembly shown in Fig. 1;

Fig. 3 is a horizontal cross-section taken approximately in the plane of line 33 of Fig. 1;

Fig. 4 is a horizontal cross-section taken approximately in the plane of line 44 of Fig. 2;

Fig. 5 is a vertical cross-section taken approximately in the plane of line 5-5 of Fig. 1;

Fig. 6 is a fragmentary perspective view of a Window section; and

Pig. 7 is a perspective view of a spline or filler strip suitable for connecting adjoining sections.

Generally, the invention resides in providing a window section or unit adapted for assembly with similar units to provide a sectional window having a plurality of lights, the units being constructed so that, without modification, the same units may be used to assemble a sectional window of either the straight line type or the bowed type. This is accomplished by providing a pair of spaced interlockable means in each side stile and so shaping the outer face of the stile that the stiles of a pair of units may be brought into abutting relationship and connected to each other by either one or the other interlockable means to selectively furnish either a straight line type window or a bowed type window.

As illustrated, each window panel, section or unit A comprises top and bottom rails it it? connected in any suitable manner to the spaced side stiles 12, 12. The rails and stiles may be made of any suitable material, such as wood or aluminum. The rails are provided with interlockable means to permit the assembly of two or more units in vertical end-to-end relation, such means preferably comprising longitudinally extending locking grooves 14, 14 shaped to matingly receive a filler strip or spline in when the groove in a bottom rail is aligned with a groove in a top rail of an adjoining unit. The grooves may be dove-tail shaped or formed with an opening and outwardly tapered side walls terminating at a base which is wider than the opening.

To connect the units in side-to-side relationship, the

outer face of each side stile is formed to provide a straight section or portion 18 and a portion 20 inwardly sloped with respect thereto depth-Wise of the stile. As shown for example in Fig. 3, the straight portion 18 is substantially at a right angle with respect to the front face, desig-" nated 22, of the window unit, whereas the inwardly sloped portion 20 is inclined at an obtuse angle with respect to the parallel rear face, designated 24, of the window unit. Thus, each unit has a straight portion on the outer face of each stile extending rearwardly the same distance, approximately one-third to one-half the depth of the stile, with the straight portions on each side parallel to each other. The inclined or inwardly sloped portions 20 of each stile of a unit converge inwardly in a depth-wise direction or toward the rear side of the unit, these per-3 tions having equal length and being flat for abutting engagement with a similar portion of an adjoining unit. The straight portion 18 is provided with means 26 for interlockably connecting adjoining units when the straight portions of a pair of units are placed in abutting relationship. A second, and laterally spaced interlockable means 28 is provided in the inwardly sloped portion 20 to connect a pair of units when their inwardly sloped, portions are brought into abutting relationship. Prefer ably, and as illustrated, both interlockable means are in the form of longitudinally extending dove-tail locking grooves which, when aligned with each other, are adapted to receive a filler strip or spline 16 to connect the units.

Figs. 1, 3 and 5 illustrate a sectional window assembled of the described window units A to form a straight line type of window. The vertically arranged lights are provided by placing one unit on top of the other and .passing the splines 16 into the grooves 14, 14' of adjacent top and bottom rails. To connect the units in side-to-side relationship, the units are brought together with the straight portions 18 in abutting relationship and the locking grooves 26 in alignment. The splines 16 are then pushed into the aligned grooves to interlock or connect the units.

In this assembly, the inside ends of the stiles, desig- To cover these. openings, vertically disposed cover strips or jamb blocksnated 30, are spaced from each other.

32 are inserted in the openings, as shown in Fig. 3. Each jamb block comprises a flat base 34 having a projecting portion 36 extending forward therefrom, the sides 38 of the projecting portion tapering inwardly for mating of the stiles.

of each groove 28. To cover the seam or line'of'abutment between adjacent window units at the front, vertically extending cover strips or mullion casings 42 may be secured over the abutting edges.

To construct a bowed or bay type window, as" show in Fig. 2, from the described window sections or-units A, the same procedure is followed for connecting the units in vertical relationship. To assemble the units in side-to-side relationship, the units are tilted, as shown in Fig. 4, so that the inwardly sloped portions 20 abut each other. A locking bar or spline 16 is inserted in the aligned locking grooves 28 to connect the units. The front or straight portions 18 being laterally spaced from each other at the front of the assembly, vertically extending cover strips or mullion casings 44 are placed over the openings. The covering strip is provided with laterally extending portions 46 to overlie the front faces of adjacent stiles and a central stud 48 is received within the opening between the stiles. To cover the seam or line where the units abut each other on the inside, vertically extending strips or inside mullion casings 50 may be secured thereover.

I window.

The. described window unitsmay be made to provide lights of any desired type. The lights may be of the The former is illustrated; eachs'ection, panel; or unit being providedwitha frame 52; set therein, and. the framemay be rabbeted to receive the sash or glass 54 together with weather stripping 56 around its edges, and suitable molding 58 may be. provided for'holding the glass within the frame, as is well .known in the art. It will be. apparent that any combination'of stationary, awning and hopper type, lights may be assembled into a sectional window.

It is believed that the advantages of the described window; units will be. apparent from the foregoing detailed description. It will also be apparent that while the inventionvhas been shown and described in its preferred form, changesmay bemade without departing from the spirit and-scope of the. inventiomas sought to be defined inthe following claims.
