- a rate of extrusion molding of the plastic interior members is substantially smaller than a'rate of extrusion of the metallic exterior members. If the frame or casement were assembled with pairs of horizontal and vertical pieces having four distinct cross-sectional shapes, such an imbalance in productivity would cause an over-production of the exterior members or a shortage of the interior members, resulting in reduction of the productivity of the frame as a whole.
- the interior members so constructed in accordance with the invention as to have an identical cross-sectional shape can accommodate the imbalance in productivity between the interior and exterior members and hence avoid the foregoing problems.
- the interior members 19-22; 106-109 have their respective surface areas coated with the layer of weatherproofing material 133 such as weatherable paint, weatherable plastics or the like, which the surface areas are exposed to the air as the window assembly 10 is mounted on the building wall.
- weatherproofing material 133 such as weatherable paint, weatherable plastics or the like
- the layer 133 makes the plastic interior members 19-22; 106-109 weatherproof against sun light irradiated thereto, and polluted liquid or gases which are liable to cause deterioration or change of properties of the plastic interior members 19-22; 106-109.
- the weatherproofing material layer 133 further extends over part of the exterior members 23-26; 110-113 beyond the connections or joints 53b, 80b, 100b between the respective interior and exterior 19-22; 106-109 and 23-26; 110-113, making the connections proof against rain, wind and other foreign material.
- connections or joints 53b, 80b, 100b between the respective extensions 47,74,97 and the respective stepped walls 32, 56, 82 are located closer to the building wall such an extent that they are covered with the exterior part 54 and hence made proof against rain, wind and other foreign material.
- Each of the horizontal and vertical members 12-15; is assembled by first spreading the extensions 47, 50; 72, 74; 95, 97 of the respective exterior member 23-26 outwardly.
- the interior member 19-22 is then inserted between the extensions 47, 50; 72, 74; 95, 97 until its outer sidewall 35; 58; 84 is brought into abutting engagement with the inner sidewall 45; 70; 93 of the exterior member 23-26.

Theinner wall 91 includes anintegral extension 95 having at its distal end alocking protuberance 96 snugly received in therecess 86 in theinner wall 81 of the interior member 21 (22). The outer wall 92 also has anextension 97 formed integrally therewith and extending in overlying relation to the steppedouter wall 82 of the interior member 21 (22). Theextension 97 has a pair of inwardly directedlocking protuberances 98, 99 adjacent to its proximal and distal ends, respectively for abutting engagement with the recess 87 in and thestepped portion 85 of theouter wall 82 of the interior member 21 (22). A connection 100a or joint between theouter extension 97 and the steppedouter wall 82 is covered with theexterior siding 54. Theweatherproofing material layer 133 covers theinner wall 81 of the respective inner member 21 (22), a portion of theinner wall 91 of the respective exterior member 25 (26) and anotherconnection 100b between theinner walls - The double glazed
casement 31 is pivotably mounted on one of thevertical pieces 14 of theframe 11 by means of hinges 101 (only one being shown in Figure 2) and comprises a pair ofhorizontal pieces 102, 103 (Figure 1) and a pair ofvertical pieces 104, 105 (Figure 2) connecting thehorizontal pieces plastic material - Each interior member 106,107 of the horizontal pieces or top and
bottom rails upper wall 114, a lower wall 115 and a pair of inner andouter sidewalls 116, 117 connecting the upper andlower walls 114, 115, the upper andlower walls 115, 116 having recesses 118,119 adjacent to their respective outer ends or edges, respectively. Theinterior member 106 further includes anintegral mounting flange 102 depending from the inner end or edge of the lower wall 115 for supporting glass panes together with acooperating support 121 which is attached to theexterior member 110 of thetop rail 102. Theexterior member 110 includes asidewall 122 and a pair of spaced upper andlower walls sidewall 122. The upper andlower walls lower walls 114, 115, respectively. Theupper wall 114, outer sidewall 117 and mountingflange 120 of theinterior member 106 and a portion of theupper wall 123 of theexterior member 110 are coated with theweatherproofing material layer 133. For clarification, only thetop rail 102 has been explained in structural details thereof by affixing reference numerals thereto. - As will become apparent from Figures 1 and 2, the
interior members vertical pieces bottom rail members exterior members bottom rail 103 andvertical pieces top rail member 110 described above, and structural details thereof can therefore be omitted. - The mullion 27 (Figure 2) consists of an inner member of thermal
insulating material 127 such as thermal insulating rigid plastics and an exterior member ofmetal 128 such as extruded aluminum joined together by interlocking engagement ofrecesses locking protuberances interior member 127 and a portion of theexterior member 128 are coated with'theweatherproofing material layer 133. - As described hereinbelow, the respective interior members of thermal insulating plastic material 19-22; 106-109 and the respective exterior members of metal 23-26; 110-113 are joined directly together without connecting members interposed therebetween, with the result that the respective horizontal and vertical pieces 12-15; 102-105 and hence the
frame 11 and thecasement 31 have excellent thermal insulating properties and can be assembled easily with an increased degree of positional stability and firmness. - Furthermore, at least three
interior members frame 11 orcasement 31, reducing a number of components to a minimum and increasing a rate of production. - In this regard, it is noticed that a rate of extrusion molding of the plastic interior members is substantially smaller than a'rate of extrusion of the metallic exterior members. If the frame or casement were assembled with pairs of horizontal and vertical pieces having four distinct cross-sectional shapes, such an imbalance in productivity would cause an over-production of the exterior members or a shortage of the interior members, resulting in reduction of the productivity of the frame as a whole. The interior members so constructed in accordance with the invention as to have an identical cross-sectional shape can accommodate the imbalance in productivity between the interior and exterior members and hence avoid the foregoing problems.
- The interior members 19-22; 106-109 have their respective surface areas coated with the layer of weatherproofing
material 133 such as weatherable paint, weatherable plastics or the like, which the surface areas are exposed to the air as thewindow assembly 10 is mounted on the building wall. - The
layer 133 makes the plastic interior members 19-22; 106-109 weatherproof against sun light irradiated thereto, and polluted liquid or gases which are liable to cause deterioration or change of properties of the plastic interior members 19-22; 106-109. Theweatherproofing material layer 133 further extends over part of the exterior members 23-26; 110-113 beyond the connections orjoints - The connections or
joints respective extensions walls exterior part 54 and hence made proof against rain, wind and other foreign material. - Each of the horizontal and vertical members 12-15; is assembled by first spreading the
extensions extensions outer sidewall 35; 58; 84 is brought into abutting engagement with theinner sidewall 45; 70; 93 of the exterior member 23-26. With this condition, theextensions protuberances recesses 37, 38; 60, 61; 86, 87 and the steppedportion 36; 56; 85 of the exterior member 19-22.
