vertically sliding window Figures 15 to 18 are sectional views of strips and frame units in conformance with the invention for fixed Figure 19 illustrates an example of a stamped znetal strip sheathed in the extruded and Figure 20 shows a sectional view of a door In order to simplify the ing parts in the various Figures bear the same reference A long thin planar metal strip 1 shown in section in Figure 1 is totally or partially covered with a coating of thermoplastic material for by ing material on the metal strip in the shape indicated in Figure 1 including the integral longitudinally extending ribs 3 and 4 and the marginal part 2 e first step in ing a frame from the coated strip is to convert the strip as shown in 1 to the shape shown in 3 by reducing the width of the strip thus forming a pair of longitudinally extending channels which define a pair of grooves for receiving the edges of window After so forming the coated the ribs will be located at the mouth of each channel extending thereinto for the purpose of sealingly engaging a window panel in the The next step in fabricating a frame is to cut the formed strip to a length corresponding to the peripheral dimension of the window opening to be equipped with the length of formed strip is then bent lengthwise to conform to the shape of the window opening such that the channels open inwardly of the At this the ends of the length of formed strip will be in and can be joined together by welding the metal reinforcing for to establish a closed frame with a continuous Having thus fabricated a it is inserted into the dow opening illustrated in 3 opening in door In this case ribs 4 en a e the window o enin in door 5 and form a 6a seal Margin part 7 of the frame can then be bent easily by hand over a flange 6 which defines a part of the window opening in door Subsequent to the separate shaped trim or cover strip 8 can be inserted as shown in 3 to complete the assembly of the frame into the window opening of the door and form a decorative joint In the case of Figures 4 to one of the strips or ribs 3 is formed by a section 10 which fits over the flange 6 in manner and simultaneously fits over the extension 9 of the metal strip as shown in Figure In additio the extrusion has an extra sealing strip 11 forming a trim or covering strip on the side of the door opposite to the flange In the case of Figures 7 the extrusio has a bent hook flange 12 along one of its edges and a space is left between this flange and body of the whereby the flange can hook engage over the flange 6 in the window To fix the frame unit securely to the it suffices to straighten out the flange 12 for example by pulling on a cord which is inserted at the bottom of the slot so as to enable the flange 12 to pass ove the flange 6 of the Due to its resilient properties this flange 12 regains its former shape on release so as to be with the flange this assembly operation has been the door will have been provided with a frame unit ensuring an easy operation and tight sealing of the slidin window On the opposite side of the extrusion to the flange 12 is provided the integral strip 11 which serves as a trim and sealing The frame unit being attached to the the strip 11 projects over the door leaving no unsightly gap to cause between the frame unit and the body on which it is The outer surface of the unit has sealing strips 4 compressed against the frame structure during the These strips offset the tolerances generally accepted in the construction of vehicle leaving no play between the frame unit and the The extrusion shown in Figures 12 and 13 is of similar but has a section It is designed for the installation of vertically operated sliding window panels opposed to the preceding system for horizontally sliding window The part of the extrusion designed to form the base of the frame unit is provided with a slot 18 allowing passage of the vertically sliding window panel She window panel 19 will be guided within the door by two straight standard runners 20 fixed in the door on each side of the vertical edges of the window panels In this special case of vertically sliding window the invention eliminates the interior and exterior felt strips normally installed in conventional window frames with the object of ensuring of the window panel at opposite vertical sides of the enabling the panel to penetrate into the lower part of the In the strips installed above the opening provided for passage of the window panel ensure of the inner and outer surfaces of the extrusion shown in Figure 15 after extrusion md in Figure 16 after is similar to the section shown in Figure without the the strips 3 being replaced by ribbed surfaces 21 designed to bear on the fixed window The extrusion shown in Figure 17 before shaping and in Figure 18 after shaping is designed to form a double a pair of channels for two fixed windows Four sealing strips 21 are Figure 19 shows an example of a metal strip 1 with spaces 25 which give the required flexibility for It will be understood that the examples described above and illustrated in the drawings are not She extruded reinforced strip utilised in the construction of the frame unit may take varying forms by a judicious choice of extrusion stri bent or curved in different enables frame units of extremely varied sizes and appearance to be the combination of the attaching means with one or the other of the above considered solutions open up a wide range of insufficientOCRQuality
