Description

Patented Jan. 19, 1954 WINDOW SASH FRAME STRUCTURE Michael J. Nardulli, Elmwood Park, Ill., assignor to Michael J. Nardulli, Angelo F. Naples, and Peter F, Nardulli, as trustees, and known as Western Engineering Trust Application August 10, 1949, Serial No. 109,470
4 v Claims.
including corner brackets that extend along or into channels formed in the extruded frame elements. In making such sash it is of course desirable that the frame elements be so connected as to enable the elements to be separated when it is necessary to put new glass in the sash, and where provision has been made for such disassembly, such attachment or joining of the sash elements at the corners has been accomplished by forming bores through the metal members so that screws might be extended through such bores and into threaded engagement with the corner brackets, although in some instances, the threaded portion has been formed in the frame element and the attaching screw has been extended througha bore in the corner bracket. With either of such constructions, it has been necessary to accurately relate the screwreceivingo penings in the corner brackets and the frame elementsfand this, of course, has introduced problems of cost which have been objectionable. In an effort to reduce costs, some manufacturers have resorted to peening of the sash elements or the corner brackets to effect the desired rigid connection therebetween, but this has, of course, made it almost impossible to disassemble the sash frame elements for glass replacement. It is, accordingly, an important object of the present invention to simplify the connection of metallic frame elements in sash of the aforesaid charact and to afford a simple connection that may be easily released for purposes such as glass replacement. A related object is to enable such joining of the frame elements to be accomplished in such a way that the formation of a screw receiving bore or threaded opening in the frame element is eliminated.
Other and related objects are to enable'a fastening screw to be placed in an effective relation between a corner bracket and a frame element in such'a way that an effective interlock is afforded between the screw and the frame element as an incident to the tightening of the screw.
More specifically, it is an object of the present invention to afford an extruded sash frame memher in which an undercut channel is afforded into which the corner brackets may be extended or- 2 inserted from the ends of the frame elements, and to so form the overhanging portions of such slot that a fastening screw extended through the slot and into threaded engagement with the corner bracket may be tightened into engagement with such overhanging portions so as to interlock the screw against displacement endwise along the open edge of the slot. Another object is to enable sash frame elements to be prepared for shipment merely by performing the usual mitering operation at the ends of the sash frame elements, and a related object is to enable the fastening or securing operation to be performed merely by tightening screws that are carried by the corner bracket that is provided at each corner of the sash.
Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings, which, by way of illustration, show a preferred embodiment and the principles thereof and what I now consider to be the best mode in which I have contemplated applying those principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.
In the drawings:
Fig. 1 is an elevational view of the outer face of a storm sash constructed in accordance with the present invention;
Fig. 2 is an enlarged portion of Fig. 1; c
Fig, 3 is a view similar to Fig. 2 and showing the way in which the frame elements are put in position with respect to the corner bracket and the glass panel;
Fig. 4 is a cross sectional view taken substantially along the line 4-4 of Fig. 2;
Fig. 5 is an enlarged portion of Fig. 4 showing the relationship of the fastening screw to the frame member and the corner bracket;
' Fig. 6 is a front elevational view of the corner bracket;
Fig. 7 is a cross sectional view taken substantially along the line "l1 of Fig. 6; and
Fig. 8 is a view similar to Fig. 4 and showing the invention as it is incorporated in a metal framed screen.
For purposes of disclosure, the invention is herein illustrated in Figs. 1 to 7 as embodied in a storm sash l0 having a glass pane II that is supported within a frame l2, such frame being formed from similar extruded metal frame elements IS. The frame elements l3 are enjoined or connected together by means including corner brackets l4. As will be evident in Fig. 4 of the drawings, the extruded metallic frame member 13 has an inner edge portion 13A and an outer edge portion I33, and between these inner and outer edge portions, a pair of similar grooves 13G are formed so that such sections are joined by a relatively thin web portion I3W, this form being such as to afford adequate strength while at the same time conserving in material, The inner edge portion BA is formed with a groove MG into which the edge of glass panel H is adapted to be inserted, and this groove HG inthe present case is so formed as to afford space to receive a" cushioning and sealing member 15 that is of generally U-shaped form and is front-a resilient material such as rubber so that it may embrace the edge of the-glass pane and fit snugly into the glass receiving groove 14G.
The outer edge portion 133 of. the framememher I3 is formed with a generally ectangular channelv [6 that opens laterally through the outer face 11 of the frame element l3, and in this outer face, a slot IBS is formed. aswiljl be evident in Fig. 2 of the drawings. slot at its inner face. opens into the groove 16 in a substantially symmetrical relationship with respect .t'otheqcpposite sidewalls of the groove IfiQand thus overhanging lips. .I-GLar-e formed-r Thelips 46L are formed with rabbetted grooves- L8, as will be evident in Fig. 5 of thedrawingsrand the space withinand between these two rabbetted grooves 18 is related, as will hereinafter be described, to the form.
and size of the head 20H of attachment'scnewsm that are; utilized to cooperate with the carrier brackets 1M.
The corner brackets .areformed with two right angularl-yv related arms; MA and MB; and. each ofthese arms, as will. be: evident: Figs. 4 and 7,, is of a rectangularcrosssection that is complemental to the: farm of the-groomer slot i6 :so'that the arms (of the: corner bracketamay be extended into SUQhiEFOGMES 1'6 asshown in'fligs. 3 and 4.. In. this connection it 'wi-ll he noted that the adjacent ends. of the frame elements are IIIitBIEd'ZZLS BIt 212:: swath-aft thesemitened edges may be engaged when thexframe elements are placed in the desired right angle relationship. The corner bracket. :44 thus :be inserted into the open ends xsof the: grooves: 18;. as shown :in Fig :3, and the screws 20 are arrangedito 'zbe aextended through thegopen slat: slhS-Eandrintothreaded: eng-agement with :bmes 23- formed: the-respective arms of the corner: :bracket; The head; 12-.0H of each screw is ithe' -pmeseritizcase zin it'he torimaofl a Phillips head screw, and the headlrigi-cylindrica la in form and with a flatilb'ottom surf-ace so that the head 20H may 'be'fully received within the clear ance space afforded =by the grooves [:85 Thescrews 20 may thus be termed binder head screws; The arrangement issuch that the screw headfl OHLmay be drawn inwardly sorasztotbe flush with rorzscmewhat below the outer face I! of the frame element, and as 'th'eirscrew'iim fis'i drawnxinto' this relationship, the flatilowersurface'of theiscrewsheadim is clamped'againstthe .flat and 'co'planar'zsunfaces of the overhanging portions" il 6L, asrwylll': ibe evident in Fig. 5 of the drawings, and this produces .an: interlocking actionzibetween the screw head .andltheframe element'sozthatxthemorner bracket 14. is. fixed against, displacement ilongitudinally with .respect to thel framexelementi i113.
.Itwillabe aevident nfmourse,rzthatrtlilsxmudewf" 4 connecting the frame elements may also be applied to metallic frame elements that are to be used in producing screens, and in Fig. 8 of the drawings, such an arrangement is shown. Thus, in Fig. 8 the metallic frame element is identified as I I3, and this frame element has an outer portion H33 that is the same as the outer portion i313 of Fig. 4. The frame element H3, however, has an inner portion USA that is formed with a laterally opening channel IMG that is afforded merely to reduce weight while at the same time affording a frame element that is of the same width as the frame element H3. Between the roove [MG and the section 3B, an outwardly opening groove G is formed, and this opening has a slot I I6 and an overhanging ledge I II. This groove 5G is' arranged to receive the edge portion of a screen panel IH, such screen panel being" forced into the groove I I5G by a resilient retaining member I30 that is forced into the groove through the slot 1 i=6. Within the groove 1 I561, a series" of teeth l3'l are afforded to interlock with edge portions of the screen IN to prevent undesired movement of the screen in relation to the frame element H3:
Through the use of the present invention, the extruded metal members, such as the member l3, maybe formed from a relatively soft metal such as aluminum; and in" preparation of the frame elements of the desired size for a particular sash, itis-merely' necessary toperform the mitering operations which afford the miter'ed" ends '22, and these" frame elements may then be assembled merely by association of the corner b a ets d screw elements therewith, it being u necessa y under-the present invention to perform any orin or oth r forming operations-0n the mi 'jr d' sa h frame element's. When the f ame elem'ent'slhav thus been associated in acicor'dan ce with the resent invention, it isposs'ible to detach such frame clementsfolr replacement .of the glass or screen panell-and this maybe accomplished through the use ofordinary tools.
From the foregoing description it will be apparent that-the present invention affords an improved and more advantageous way of manufacturing and: assembling metal frame window ;s,ash or screens, and it will also be apparent that the-extruded metalframeelement that is affended.- by the present invention-is of such a form and character as- .to be adapted for interlocking e gagementwithna fastening element such as a screw, merely as incident .to the tightening of the--screw,thereb y gtoqeliminate costly forming or boring-operationssuch as-those that have been-required-nnder.p ior practi e 7 Thus, while-I have illustrated and-described the prefemedembcdiment ofmy inventiOIL- it is 4 01 understood-that t is ispab1e of va ation and modificationuand I therefcre do not wish to=he limltedt0 th precis d tails s t fo h, but desire to avail myself of such changes and alterations as fall the purview -.ofthe f lowing claims.
