mans/v70)? Louis Peri/siefn FIG-l2 REINFORCED FRAME MEMBER OF ELASTOMERIC MATERIAL SUMMARY OF THE INVENTION An object of my invention is to provide an elastomeric framing structure for windows; walls and the like composed of rigid reinforcements as integral parts of elastomeric frame strips or members thereby providing. a nonsagging, shock-absorbing, watertight enframent which is impervious to outdoor weathering and nonconducting as respects temperature changes and by which cost of maintenance is substantially eliminated.
Another object is to providea construction in which a rigid elementimbedded in elastomeric material makes it possible to I mechanically fasten the elastomeric material to a rigid support and to. other parts, such as hinge bars and the like and imparts to framing material. sufficientstrengthto withstand wind pressure higher than the wind pressure ordinary elastomeric framing material'will withstand.
Another object of my invention is to provide. an elastomeric frame strip in which the elastomeric material is allowed to vibrate andcushion shocks received by the framed material it supports without creating a thermal-bridge which would speed up temperature changes.
Another object is to provide a reinforced elastomeric strip in which a reinforcing member in the strip is secured by nonelastic fastening devices, such as screws, to a frame member. external to the strip.
. Other objects will be apparent from the following description and accompanying drawings.

' DESCRIPTION OF THE PREFERRED EMBODIMENTS by two wing parts 22 and 23 between which anvedge portion of i a nonflexible panel, such as a pane of glass 24; is received. The wing part 23 at one side of the groove 21 has aninwardly extending flap 25 which forms one, wall ofsaid groove 21.'The outer edge of the flap 25 is integrally connected by a hinge portion 26 with the wing part 23. .1118 inner side of said flap 25 is spaced from the adjacent wall 27 of the wingpart23 and'the inner edge 28 of said flap 25 is spacedfrom the bottom wall 29 of the groove 21. The part of the bottom wall 29 directly in line with the groove 21 is recessed to form alongitudinally extending V-shaped through 19. i
A metal-reinforcing member of modified angle bar shape, FIG. 2, formed of two integral flanges 30 and 31, is adaptedtto be inserted within the cavities provided in the elastomeric member 20. One flange 30 of said reinforcing member is plane and flat and is disposed within the space between theflap 25 and adjacent part of the wingmember 23. The outer edgeportion of the other flange 31 of said reinforcing memberl is shapedto form alongitudinally extendingtroughlike grooved part 32. Two opposed narrow lock ribs 33 are-provided along the spaced apart edges of the trough, like part 32 to'fit within grooves 34 in glass supporting and cushioning strips 35 of elastomeric material as more fully hereinafter explained. Suitable holes 36, FIGS. 4 and 5,, are provided-inthe bottom of the grooved part 32 to receive fastening devices, such as screws 37 which securethe reinforced elastomeric stripto any rigid external structural member, such as a window sill cover 38.
The grooved part 32 ofthe reinforcing member 30, 31 stiffens and strengthens said member and providesroom for the heads of'the screws 37 so they arenot contactedbythe glass 24 and it serves as a'receptacle for parts 39 ofthe glasszsupport strips 35.
A longitudinally extending spline receiving groove 40 is provided in the frame member 20 in offset relation to'th e groove 21 and substantially atthebase of the .wing'part 22rleaving said wing part 22 connected with the strip 20 by afairly'thin hinge portion 41 which makes it possible to incline part122 outwardlyand facilitates'insertion of thereinforcing ;bar:30; I
31 and glass 24. A filler strip or spline 42 of elastomeric material is provided for insertion into and removal fromthe groove 40 and serves to sealingly. wedge the wing part 22 against the glass 24 when said spline is inthe groove'40. Obviously this also sealingly presses the glass 24 against the flap 25 of the reinforced wing part 23. I
The reinforced elastomeric strip 20 functions as. a true frame member which is resistant to bendingin all directions and which protects and lends strength to the-glass. 24 and minimizes breakage and makes the glass easier to handle.
The elastomeric frame member 43 of FIG. 4 is generally similar to the frame member 20 shown in FIG. l but is architecturally .different in appearanceimthat it is provided with a square instead of a rounded corner. Said frame member 43 is internally shaped similarlytothe'frame member 20 to receive a similarreinforcing member. 30, 31. A glass-supporting strip 35 is shown in an operative position in saidiframe member 43. It will be understood :that'the glasssupporting strip 35 may be of any, desired length. The strips 35 are used in the bottomrails or parts of elastomeric frames wherethey are called on tosupport the weight of glass panels and they may, be
- used in the side and top rails of such frames if desired.
The elastomeric frame. member 44 .shown in. FIG. 5 is similar. to the previously. describedframe, members 20and43 except that. it has a fillerstrip or spline .45which is integrally connected with the member 44 along one edge by ahinge part 46 and is adapted to fit within agroove 47 in said member 44.
FIG. 6 shows two elastomeric frame ,members50and 51-.of modified shape and construction which. are connected with each other by strap or bar type hinge means 52. This hinge means 52 is of a well-known type of construction commonly used to support transom or ventilator sections of windows for opening and closing movement. It is not a part of this invention and is not herein described in detail. The part of the frame member 50 shown uppermost in FIG. 6 is shaped similarly to the frame member 20 and has therein a reinforcing bar 30, 31 which is connected by screws 37 with a part of the hinge means 52. Said frame member 50 has an integral flange 53 protruding from one side thereof. The frame member 51, as
shown in FIG. 6, comprises an upwardly extending flange 54, a horizontal flange 55, and downwardly extending flange 56. The two flanged frame members 50 and 51 cooperate in providing a receptacle 57 for the hinge means 52 and the flange 56 is of the proper shape and dimensions to fit within a glass-receiving groove, such as the groove 21 of FIG. 1. A reinforcing member 59 of angle bar cross-sectional shape is provided in the elastomeric bar 51 and can be connected by a suitable connector member 60, which may be a screw, with a bar of the hinge means 52. The frame and hinge means shown in FIG. 6 can be used to swingingly support smaller transom sections, such as upper transom section 95 and lower transom section 96, FIG. 12, for opening and closing movement, these transom sections commonly being used in windows containing larger panes of glass, such as panes 97, 98 and 99.
The modified elastomeric frame member 61 shown in FIG. 7 has a glass-receiving groove 62 in one side and a reinforcing member receiving groove 63 in an opposite side. The groove 63 has two inwardly protruding anchor ribs 64 and 65. The terminal portions of these anchor ribs are wider than the base or neck portions thereof. Said ribs 64 and 65 are adapted to fit within rib-receiving grooves of mating shape in the sides of a rigid reinforcing bar of generally I-l-shape in cross section which bar is formed of two spaced-apart flanges 66 and 67 connected by a medially positioned integral web 69. Fastening members, which may be screws 37, are used to secure said frame bar to any suitable support and the elastomeric member 61 is applied to the bar before said bar is secured to its support.
The modified elastomeric frame member 70 shown in FIG. 8 has a glass-receiving groove 71 in one side and is suitably recessed on another side to fit over a reinforcing member composed of two flanges 73 and 72 and a web part 74 and a wider head or outer flange 75. The wider outer flange 75 is an external member and the elastomeric part rests against it. Anchor ribs 76 and 77 of the elastomeric member 70 interlock with parts 72, 74 and 75 of the reinforcing member. An edge portion of the flange 73 is of trough shape, as indicated by 78, and corresponds to the trough shaped part 32 of the flange 31 shown in FIGS. 1 and 2 in that it is adapted to receive securing devices 37, which can be applied through holes 79 in member 70.
The elastomeric frame member 80 shown in FIG. 9 is of modified H-shape. It has two glass-receiving grooves 81 and 82 in two opposite sides thereof, a spline-receiving groove 83 in a third side and a groove 84 in a fourth side of suitable shape to receive and interlock with a reinforcing bar 85, which is shaped somewhat like an l-beam in cross section. Bar 85 can be secured to an external frame member 86 and the elastomeric member 80 applied to said bar 85.
The elastomeric frame member 87 shown in FIG. is similar in shape to the member 80 shown in FIG. 9 except that a spline receiving groove 88 in one side thereof and a reinforcing member receiving groove 89 in an opposite side thereof are of sufficient depth and are shaped to receive two auxiliary trough-shaped metal reinforcing members 90 and 91. The trough-shaped reinforcing members 90 and 91 are connected with each other by rigid connector members, which may be screws 92 and these two members 90 and 91 impart increased rigidity to the elastomeric member 87 without introducing a thermal bridge and at the same time permit said member 80 to retain its shock and vibration absorbing characteristics. The
elastomeric member 87 of FIG. 10 is adagted to be applied to and engaged with a main reinforcing bar 5' of approximately the same shape as the bar shown in FIG. 9.
