Description

1~)5~'7 This application is a division of Serial ~o. 161,817, filed January 22, 1973, now Patent No. 1,013,207, dated July 5, 1977.
The invention relates to building structures and refers more specifically to a sliding door which is esthetically pleasing, easily operated, has weathertight integrity to both air and water, has extremely high structural integrity and substantial universality of components whereby the greatest degree of versatility has been achieved from a specified inventory investment of raw material and finished goods at a relatively low cost. In one modification, the sliding door has been particularly structured to provide high efficiency and economy by modification of the sliding door frame and door panel extrusions and provision of a screen having an extruded frame with a single cross section and unique hardware.
In the past, sliding doors have not generally included all mitered corners. In particular, the jambs at the bottoms of previous sliding doors have generally either been straight-cut across the sill, or where the sill has been inclined, the jambs have been diagonally cut, whereby a high degree of orientation is given to the frame members of previous sliding doors which is undesirable from an inventory and thus cost point of view.
Further, wherein mitered corners have been provided in sliding doors in the past, no means have been provided to prevent mis-alignment of the mitered joints on securing the members forming the mitered joints to each other. Thus, mitered joints in the past have required skilled workmen to produce and have often been misaligned.

105'~
In addition, in prior sliding doors, either two pockets formed by three fins, one pocket for each of a movable and fixed door panel with a fin between the door panels, have been provided in the frame head, or alternatively, three pockets have been provided between two outer fins and two intermediate or guide fins in the frame head for guiding the top rails of a movable and a fixed door panel, with the guide fins received in slots in the door panel top rails.
In both structures, considerablo weather sealing and/or fab-rication of weather seal inter~ocks on the door panels has -been necessary. Again, the added weather sealing and fabrie ``
cation together with the orientation which the fabrication and/or weather sealing require has given the components of and the finished door panels thus constructed has added an undesirable cost factor and inventory requirement to prev-ious sliding doors.
Further, previous sliding doors have usually not been suitably weathertight without expensive and sometimes compli-cated structure. Thus, for example, a complete aluminum s~rD~nd has often been provided in the past for glaiing sliding door panels from the inside to prevent popping of the glazing panels out of the frame therefor under high wind loads. Complicated structure has sometimes been required to prevent entire slid~ng door panels from being blown out of the outer frame therefor.
In addition, with prior sliding doors, stopping of the sliding door on opening has sometimes been a problem.
Wherein stops have been provided only at the tops or bottoms of the movable door panel, the door panel tends to cock in the

-2-105'~6'Z7 frame on hitting the sop, thus wearing door panel rollers and damaging the outer frame or movable door panel. Prior stop structures have in addition also required separate fabrication of the frame member to install and sometimes themselves have b~en complicated and therefore expensive.
Central stops have in general not been utilized dur to their appearance and the fact that they tend to damage the door and/or frame members due to single-point contact, therewith centrally thereof.
FuPther, with prior sliding doors it has often been possible on jiggling the movable door panel to unlock it and t~ -ga~n entrance into the bui~ding in which the doors have been installed. It has generally been impelsible with sliding doors to lock the movable door panel in a partly open position to provide, for example, venti~ation without allow-ing smallchild~n to go out or prowlers ~o come in the doors.
Also, it has been difficult in the field, with the size of sliding doors usually installed today, to obtain square structurQl openings for the sliding door structures. It has therefore been necessary to adjust the movable door panel of slid~ng doors to compensate for the out-of-square door openings. In the past, such adjustment has usually been accomplished by adjusting the movable door panel at both sides thereof, which requires separate adjusting mechanisms and separate adjustments which are not entirelv independent a~ both sides of the movable door panels.
The 81 ding screen doors provided with the sl~ding door structures of the past have usually had roll formed frames and have been required to have deep pockets in the upper and lower frame rails to receive adjustable rollers at the corners of the

-3- -105Z~Z7 screen doors. The frame members have therefore often been of different cross section and have not always been provided with mitered corners. In addition, in the past, screen members have been secured to the frames in rectangular recesses receiving either round or rectangular splines.
Such structure has not always securely held the periphery of the screen to the fr~me. Separate handle and locking struc-tures have usually been provided with prior sliding ecreen doors. ~ ~
Further, in the past, sliding doors have not always .
been adapted for installation in a wide variety of building structu*~s with a single frame, as for example, bu~`lding structures which require nailing fins for securing the frame to the exterior of the building structure. In addition, nei~her interior nor exterior trim for sliding doors have normally been readily available and extensions of slidn~g door frame sills have in the past generally field fabrica-ted.
In accordance with the present invention, there is pro-vided a sldding door including an outer frame having four mitered corners and a plurality of door panels, at least one of which may be fixed and one ~f which is movable, which outer frame and door panels and the individual mem~ers there-of have been constructed with a minimum of orientation to provide the greatest degree of versatility from a specified inventory investment for both raw and finished goods. Thus, where~er~ possible the me~bers of the sliding door structure of the invention are interchangeable right-left, up-down in-side and outside.
In one modification of the preferred embodiment of ., .

lOS'~6Z7 the invention, the members of the frame and door panels have been constructed to provide a cross section which is effic-ient yet particularly economical.
The mitered corners of the outer frame are provided with integral offset abutment structure on one member thereof adapted to engage the other member forming the corner, whereby the corners may be quickly and accurately aligned in assembly and tightly connected without the dan-ger of misalignment on drawing the miter-cut members tightly against each other.
The head of the outer frame of the sliding door st~cture disclosed is provided with a single guide fin for -guiding a movable door panel and no fin is positioned between the movable door panel and the fixed door panel, whereby ~ ~
weather sealing of the door panels is particularly simple ! : . ' and efficient. Hairpin shaped top guide members are provided ~- -between the top of the movable door panels and ~uide fins.
Unique weather seals are provided at both the upper and lower railæ of both the movable and fixed panels of the sldd- -~
ing door structure which ~lso aid in maintaining the struc-tural integrity of the sliding door.
Further, in one modification of the preferred embodi-ment, the fixed ~oor panel of the sliding door structure of the invention is retained at its fixed side rail in assembly with a jamb of the outer frame by staked-out portions therein. The other or free side rail of the fixed door panel of the sl~ g door structure may be secured to the sill by a weather stop bracket to enable the sldding doDr structure to withstand very high winds.

. . , . ~

l()S~Z7 In another modification of the sliding door structure of the invention, the fixed door panel may be retained at its fixe!d side rail in assembly with a jamb of the outer frame by screws extending through the jamb of the frame and into the fixed side rail of the fixed door panel. In either modification, the top rail of the fixed door panel may be secured to the head of the outer frame by screws.
Further, a two-member glazing system is provided for the door panels in one modification of the preferred embodiment of the invention which enable the glazing panels to withstand very high wind pressures and permit glazing of the door panels from the in-side of a building in which the sliding door is installed.
Sliding screen door structure is provided in the sliding door structure which is completely reversible end for end, inside for outside and left to right comprising head, jamb and sill frame extrusions secured together at their ends into a rectangular frame defining a flat plane. Each of the extrusions of the frame in-cludes a cross section comprising an inner and outer rectangular portion separated by a solid web portion, which cross section has a center line extending centrally of and parallel to the web por-tion within the web portion. The sliding screen door structure further includes a screen member and means securing the periphery of the screen to the frame centrally of the plane of the frame and parallel to the plane of the frame substantially midway be-tween the inside and outside of the screen door immediately adjacent the center line of the cross section of the frame extru-sions. The sliding door structure also includes a unique bumper system and separate prowler lock structure and modifications thereof.

` 1(~5'~6~7 To compensate for out-of square door openings in in-stallation, the movable panel of the sliding door is positioned on an expander and a wedge and a wedge block are secured to the expander and to one edge of the movable panel of the sliding door structure respectively, having engaged, inclined plane surfaces for pivoting the movable panel in the plane of the movable door panel about one edge thereof. The wedge is constructed to fit within the expander at two different levels to provide coarse movable panel adjustment. Fine adjustment of the panel is pro-duced by relative movement of the wedge and wedge block. Wedgeand wedge blocks may be provided at one or both edges of the movable door panel.
The sliding screen door structure of the invention may be utilized outside of the sliding door structure with which it is disclosed and is completely reversible end for end, inside for outside and left to right and includes head, jamb and sill frame extrusions secured together at their ends into a rectangular frame, each of which extrusions has a cross section comprising an inner and outer rectangular portion separated by a solid web portion, which cross section has a center line extending centrally of and and parallel to the web portion within the web portion, a screen member, and means for securing the periphery of the screen member to the frame centrally of the plane of the frame and parallel to the plane of the frame substantially midway between the inside and outside of the screen door immediately adjacent the center line of the extrusion cross sections.
In a more economical modification of the preferred em-bodiment of the sliding door structure, the screen frame members are extrusions and are provided with unique spring loaded adjust-able roller assemblies at all four corners thereof which do .-, 105~ '7 n ot require deep upper and lower rail cross sections. The screen s,' , ~
frame extrusions of this modification are also constructed to el- -iminate the necessity of separate screen handles and to facilitate loc~ing of the screen to the sliding door structure outer frame by particularly simple lock structure and to receive the periphery of the screen member in a recess having the cross section shape of a parallelogram, which recess is operable in conjunction with a similarly shaped spline to more securely hold the periphery of the screen member The sliding door structure of the invention is ~mpleted with a nailing fin adapter for securing the outer frame in building openings requiring nailing fins. Inside trim extrusions such as resilient bullnose sections adapted to accommodate flooring of different thickness, and exterior trim members including members having a soft core and harder exterior skin are also provided for use in conjunction with the sliding door structure, along with a sill adapter for extending the width of the sill of the outer frame of the sliding door structure. In sliding door structure having two movable door panels, a unique astragal adapter is secured to the locking rail of one movable door panel for receiving the lock-` ing rail of the other movable door panel with the movable door panels in a closed position.

The first modification of the preferred embodiment of the sliding door structure 10 shown in Figure 1 includes an outer frame 12, a fixed door panel 14, a movable door panel 16 and a movable screen panel 18. The sliding door structure 10 may have a plurality of fixed and/or moving door panels.
Thus, the invention is not intended to be limited to sliding doors having a single fixed door panel and a single movable door panel.
As shown, the outer frame 12 includes a header or head extrusion 20, jamb extrusions 22 and 24 at opposite sides of the 1052~iZ7 sliding door structure 10 and a sill extrusion 26, which extrusions have the cross sections best shown in Figures 2 and 3. Each of the four corners of the outer frame 12 are mitered as shown in Figures 27 through 29 and may be held together by suitable screw means 25. With all four cornera being mitered, the ~ambs are universal in that they have no left, right, up or down orientation.
To air in securing the mitered corners of the frame 12 together inthe desired alignment, one or more portions 31 of the jambs 22 and 24 at the ends thereof are offset or de- -pressed as shown hest in Figure 28 to provide an end abut-ment 33 against which the side of the web 35 of the head 20 and a similar portion of the sill 26 are urged by the screw means 25 extending into the screw runners 37 in the jambs 22 and 24 in assembly of the frame 12. With such struc*ure, the mitered members at the four corners are not permitted to slip past each other along the miter joint as might other-wise happen if the securing screw means 25 are dr~wn too tight. The mitered corners of the frame 1~ m~y thus be accurately constructed by relatively unskilled workmen. It will be understood that the miter joint aligning concept embodied in the abutting portions formed in the jambs is not limited to extrusion structures.
The fixed door panel 14 includes a fixed door panel frame 28 having a top rail 30, a bottom rail 32 and free and fixed side rails 34 and 36 respectively, again~ having the cross section shown best in Figures 2 and 3. The side rails 34 and 36 extend the entire length of the fixed door panel as shown best in Figure 1 and are secured to the top and bottom rails 30 lQ5'~Z7 and 32 at opposite ends thereof by suitable means such as scre~s or the li~e. A glazing panel 38 is secured in the `~
fixedi door panel frame 28. Each ~f the top, bottom and side rails of the fixed door panel 14 is also substantially univ~rsal in that they have as little orientation as possible so that the complete panel 14 as well as the individual members thereof may be used for different sliding door con-figurations.
The sliding door panel 16 includes a top rail 40, a bottom rail 42 and locking and free side rails 44-~and 46, respectively. Also as before, the side rails 44 and 46 ext-end the full length of the movable door panel 16 and are connected to the top rail 40 and bottom rail 42 at the op-posite ends thereof as shown best in Figure 1. The glazing panel 48 is secured in the movable door panel 16 as before and all of the members of the movable panel 16 are construc-ted without particular orientation when possible so as to be interchangeable.
Thus, the sliding door structure 10 may be cDnstructed in a great number of configurations with a minimum of sep-arate parts such as frame jambs and panel rails and the like, and a complete inventory of sliding doors may be stocked, again with a minimum of separate sliding door elements such as exte~ior frames, fixed snd moving panel. The cost of a sl~ing door inventory and production equipment and facilit-ies is thus reduced.
The screen structnre 18 shown in Figure 1 includes the frame 50 having a top rail 52, a bottom rail 54 and side rails 56 and 58. A screen 60 is secured within the frame 50 by convenient means such as a peripheral recess 62 in the rails having screen retaining members 64 positioned therein. Rollers 66 are mounted in the top and bottom screen frame rails and run on tracks 68 and 70 in the frame head 20 and s$11 26 as shown.
Suitable handle structure 72 and latch structure 74 are pro-vided for moving the screen structure 18 in the plane of the frame 12 and retaining the screen in a closed position over the opening provided by the movable door panel 16, respectively.
The head 20 of the door frame 12 has a cross section shown best in Figure 3 which includes an outer fin 76 and an inner fin 78 which are only outside and inside trim in the door -structure 10. A fin 80 which is a seal for the fixed door panel 14 is positioned between th~ outer fin 76 and the inner fin 78 `
and separates the pocket 82 in which the screen panel 18 is received and the pocket 84 in which the top rails 30 and 40 of the fixed door panel 14 and the movable door panel 16 are positioned. A guiding fin 86 is further provided in the pocket 84 for guiding the movable door panel 16 within the frame 12.
Since the head 20 does not include a separate fin positioned between the top rails 30 and 40 of the fixed and movable door panels, no special fabrication of the interlocking portions of free side rails 34 and 46is required and removable interloking portions to facilitate universal orientation of the free side rails is not required. Similarly, since only the movable door panel 16 is provided with a guiding fin 86, spec-ial weather stripping to prevent the passage of wind and water through the door structure 10 between the head 20 and the top rails 30 and 40 is minimi7ed and uncomplicated.
Thus, the fixed door panel 14 is provided with an 105'~627 elong~ted sealing member 88 at the top rail 30 having the cross section shown best in Figure 3. The sealing member 88 performs the dual function of providing structural integrity at the top of the flxed door panel 14 between the head 20 and the top rail 30 and seals the top of the fixed door panel. As shown, the sealing member 88 has a generally S-shaped cross section con-figuration, one portion of which fits over the top of one side portion of the top rail 30 and the other portion of which fits over the bottom of the head fin 80.
An identical sealing member 90 is provided at the bottom rail of the fixed door panel 14 and as shown best in Figure 3 includes a portion fitting over one side portion of the bottom of the bottom rail 32 of the fixed door panel 14 and another portion fitting over the rib 92 on the frame sill 26. Again, the sealing member 90 provides structural integrity between the frame 12 and fixed door panel 14 at the same time that it provides a seal for the sliding door structure 10.
Alternatively~ the sealing member 94 illustrated best in Figure 5 may be used in place of the sealing member 90.
20~ When the sealing member 94 is used, the structural integrity of the fixed door panel 14 at the bottom is provided primarily by the weight of the door panel 14 resting on the sill 26 between the ribs 92 and 96. The member 94 functions primarily as a weather seal.
The sealing of the fixed door panel 14 between the fixed side rail 36 and the fram jamb 24 is accomplished by means of a flexible sealing strip 98 which may be of vinyl, felt or the like in contact with the fin 100 of the frame jamb .

105;~62'7 24 as shown be~st in Fi~ure 2. In addition, the structural inte~rity of the side rail 36 with the jamb 24 is maintain~d by the staked-ou-t portions 10~ of the sid~ ràil 3G fitting behind the returned end portion o~ -the fin 104 of the jamb 24.
If desired, the side rail 36 may be secured to the jamb 2~ by separate screws, clips or the like in keepin~ with present conventional construction.
In assembly, the sealing members 88 and 90 or 94 are positioned on the fix~d door panel 14 and the door panel 14 is positioned in the frame 12 by first placing the fin 80 in the seal 88 and pivoting the fixed door panel 14 inwaraly of the frams 12 at the bottom ~hile movin~ the fixed door panel 14 .
upward so that the bottom rail 32 clears the track 70 and rib 92. When the door panel 14 is thus positioned in the frame 12, the door p~nel l~ is allowed to drop vertically slightly to position the seal 90 or 94 over the rib 92.
The fixed door panel 14 is then moved toward the frame jamb 24 to cam the staked-out portions 102 of the side rail 36 of the fixed door panel 14 into the jamb po~k~t 106, , .
whereby the sealing strip 98 is positioned in contact with th~
fin 100 of the jamb 24 and the fixed rail 36 is locked in assembly with the^jamb 24. Removal of the fixed door panel 14 then requires the placing of~a screwdriver or the li~e between the fin 104 and rail 36 to spring the fin 104 and permit the staked-out portions 102 of the rail 36 to be removed from -the jamb 24~ Such removal of the fixed door panel can only be accomplished from the inside of the door.
Th~ fixed door~panel 14 and the movable door panel 16 .. , .,, ~ . - . .. .... . .. ~ . _ ~052627 are sealed at the interlocking portions of the free side rails thereof by the flexible strips 108 and 110 positioned in the sidle rails 34 and 46 as shown best in Figure 2. :Similarly, the locking side rail 44 of the~movable door panel is sealed in the pocket 112 of frame ~amb 22 with the movable door panel 16 in a closed position by the flexible strip 114. Strips 108~ 110 and 114 may be vinyl, felt or similar material. As shown, a s~it-able handle 116 and lock structure 118 are also secured to the locking side rail 44 of the movable door panel 16 and the frame jamb 22.
The-bottom of the movable door panel 16 is sealed by `
a sealing member 122 having a cross section illustrated best in Figure 3 and extending from the side of the movable door panel expander 124~ which will be considered subsequently. It will be noted that the sealing member 122 extends toward the outside slde of the sliding door structure 10 whereby wind pressure on the door structure 10 increases the seal provided by the sealing member 122.
The top rail 40 of the movable door panel 16 is pro-vided with a weather seal by the dual durometer sealing member126, the cross section of which is shown best in Figure 4. The portion 128 of the sealing member 126 is of relatively rigid plastic which is flexible enough to be snapped in place over the rib 130 on the head 20 of the frame 12, with the opposite end thereof being constructed to cam over and receive the end of the fin 80 of the head 20. Thus, the sealing member 126 may be positioned within the pocket 84 in the head 20 of the frame 12. With the sealing member 126 so positioned, the softer, more 1052~27 pliable portion 134 of the sealing member wipes against the upper rail 40 of the movable door panel 16 to provide a seal therefor.
Thus, both the fixed door panel 14 and the movable door panel 16 are completely sealed around their entire peri-phery when the movable door panel is closed, with a minimum number of simple sealing members. In addition, the sealing system does not orient any of the frame or door panel members so that they are a8ain as universal as possible whereby the sliding door structure of the invention may be produced with a minimum inventory. At the same time, due to the single guiding fin provided in the head member 20 and the deletion of a separating fin between the fixed and movable door panels in the head 20, the unique sealing ~embers 88, 92 or 94, 122 and 126 provided, a more efficient and less expensive sealing system for the sliding door structure 10 than has been avail-able in the past is provided.
Should the sliding door structure 10 shown in Figure 1 be installed in areas where extremely high winds of for example hurricane velocity may be expected, a weather stop bracket 136, shaped as shown best in Figure 6, is provided at the bottom of the free rail of the fixed door panel 14. In installation, the open end of the fixed door panel free side rail 34 is positioned over the rectangular portion 138 of the bracket 136 and posi-tioned within the grooves 141 in the part 142 of bracket 136.
A screw 140 is used to secure the bracket 136 to the sill 26.
In addition to the weather stop 136, the side rail 36 may, if considered necessary, be secured by a screw centrally thereof to the fin 100 of jamb 24~ and the top rail 30 may be ,oS;~
ecured by a screw to the fin 80 of the head 20 ~djac~nt the free side rail 34. With such ad~itional structul-e, the sliding door ~tructure 10 can withstand extremely high winds of hurri-cane velocity.
As shown best in Figure 7, the upper corners of the sliding door structure 10 are provided with a weather stop and prowler security member 144. The me~er 144, which is shown in perspective in Figure 8, includes the triangular fin portion 146 adapted to complete the guide fin 86 of the head 20. The fin 146 is necessary due to the mitered corner and the provision of the fin 86 on the head 20 without a similar fin on the jamb members 22 and 24.
In addition, the member 144 is provided with the rectangular portions 148 and 150 which extend across the pocket 112 in the jamb 22. The member 144 is spaced in the pocket 112 by the projections 152 and 154 thereon. The flanges 156 and 158 aid in retaining the member 144 in position at th2 top of the jamb members 22 and 24 with the upper portion o~ the fin 86 in the slot 160 between the portions 148 and 150. When in-stalled on the head 20, member 144 also aids in the alignment of the mitered upper corners of frame 12 in field assembly of ; the frame.
In use, the member 144 also serves to prevent upward jiggling of the movable door panel 16 and consequent unlocking of the latching mechanism by prowlers or the like. Thus, with the movable door panel 16 close~, the top of the locking side rail 44 will engage the bottom side of the portions 148 and 150 to prevent undesired upward movement thereof.

A simila~ function may be accomplished ~ cut-out and folded-do-~ rectangular portions such as portions 151 and 153 in the hlead 155 of the frame 157 shown in Figure 14. Such cut-out and folded-down portions may be provided anywhere along the length of the head 1~7 where they are desired, but will most uqually be spaced out across the opening provided in the sliding door structure by tlle open movable door panel.
Bumpers 154 as shown best in Figure 7 are provided at the top and bottom of jamb 24 to prevent damage to the movable door panel 16, rollers secured thereto and/or the frame 12 due to rapid opening of the movable door panel 16 and/or coc~;ing of t~e movable door panel 16 which might occur on engagement of the ~ovable door panel with a single bumper 164 at either the head or sill of the frame 12. Thus, separate stop members 164 are positioned both on the rib 130 of the head and on the track 166 of the sill so that they enyage the free rail 46 of the movable door panel 16 as the door panel approaches a fully open position.
The bumpers 164 have the cross section illustrated in Figure 7 and are provided with a slot 166 so that no fabrication of the ~; 20 head 20 or sill 26 is necessary to install the bumpers 164.
The triangular member 168 is provided at the bottom of the frame jambs 22 and 24 to close the bottom of the mitered ~ambs at the jamb fins 104. Fins 104 include the portion lOS
- which wraps around the top of a member 168 and fits within the offset 170 in the top of the triangular member 168 as shown in Fiqure 9. Before being inserted in the ends of the fins 104 at the bottoms of the jamb m~mbers 22 and 24, the triangular mem-bers 168 may be secured in position on sill 26 by means of ,. . . .

The glazing members 174 illustrated in Figures 1-3 can withstand high wind loads on the glazing panels 38 and 48.
However, such channcl type gl~zing is expensive and requires that the panels be removed and disassembled for re~lazin~.
Therefore, since interior glazing of sliding doors is desirable, as for exan~ple in apartment buildings and the like, d~-or panel top, bottom and side rails having a glazing cross section con-figuration such as that illustrated in Figure 15 including the recess i76 are provided. Such rails in conjunction with the ~lazi~g members 180 and 182 or 184 illustrated in Figures 15 and 16 provide a very high wind rcsistant glazing system which may be installed from tha inside of the sliding door and will accommodate substantially the full range of glazing panel thickn~sses from thin, single strength to thicker insulating glazing panels at a moderate cost.
With the glazing systnm illustrated in Figure 15, a glazing panel such as panel 186 is positioned in the door panel opening against the glazing flange 188. The glazing member 180 having the L-shap_d cross section having the leg 190 and the leg 192 is positioned in the recess 176 with the leg 190 as shown within the recess. A glazing member 182 or 184, dopending on the thickness of the glazing panel 186, is inserted between the gla~ing panel 186 and the portion 192 of the glazing member 180 with the projection 194 on the member 180 extending within the recess 196 in the member 182 or 184.
The modi~ied glazing membcr 191 as shown in Figure 17 ~05'~627 is a dual durometer mcmber having a relatively hard portion ~93 simil.ar to the L-shaped glazing member 180 and a relatively soft porti.on 195 similar to the glazing member 182. The portions 193 and 195 of the glazing member 191 are connected by the relatively soft, flexible porti.on 197. In inst~llation, the L-shaped por-tion 193 of the ~lazing member 191 is ins~alled in the recess 176 in the rails of a door panel and the portion 194 is rotated counterclockwise into the position shown for glazing member 182 in Figure 15. Tlle advantage of the dual durom.eter glazing member 191 is a saving in extrusion time, since only one extru-sion need be made, and in cutting and assembly time, since only one glazing member 191 need be cut to len-~th and handled.
The modified dual durometer gla~ing strip 199 illus-trated in Figure 18 has a relatively hard, L-sh~ped portion 201 and the relatively soft portion 203 connected by a frangible portion 205. In assembly of the glazing member 199, th~.L-shaped portion is positioned in recess 176 and the portion 203 is forced between the L-shaped portion 201 and the glazing panel 186.
. To facilitate movement of the sliding door panel along the guide fin 86 without galling the guide fin 86 or causing objectionable noise due to metal to metal scraping between the -- ~ movable.door panel 16 and the guide fin 86, the moving panel - top guide 200 as sho ~ best in Figure 10 is provided. The top guide 200 is provided with a hairpin shaped portion 202 wnich fits within a slot 204 in the upper end of the side rails 44 and 46 of the movable door panel 16 as shown in Figure 3. Thc hairpin shaped portion 02 o~ the top guide 200 includes a slot 206 in which the guide fin 86 is slidably received and a 105;~6Z7 flan~e 20R which aids in securing the men~er 200 in the ~lot'' '204. The top ~uidc 200 is provided with the extension 210 havinlg the spacing structure 212 on the ends thereof whereby with th- top guide 200 in position at the ends of the top rail 40, the slot 20G is position~d centra].ly of the top ra,il.
A modified moving panel top guide 214 is illustrated in Figure 11. The structure 214 is ayain provided with a hair-pin portion 216 for receiving the fin 86 and adapted to be held within the slot 204. A flexible extension 218 is provided on one side of the hairpin portion 216 which engages the side of the guide fin 86 in asse~bly and prevents jiggling of the mov-able door panel 16 transverse of the door panel in operation.
With the larg~r size sliding doors today, it is un-uqual to find a building opening for a door which is exac~ly square. Thus, adjustment of the movable door panel 16 is normally required to provide a desired fit within the frame 12, the members of wh,ich are secured in the building openi.ng and to some extent follow th~ irregularities of the building opening.
The structure shown in Figure 12 provides adjustment of the moving door panel 16 by pivoting the moving door panel about the bottom of the locking rail on vertical adjustment o~
: the free rail side thereof., The adjustment of the ~ovable door panel 16 is accomplished'through the use of expander 124, a wedge 236 adapted to fit within the expander 124, and a wedge block 238 secured within the side and bottom rails 46 and 42 of the door panel 16 in engagement with the wedge 236. In operation, the wedge'236 and the wedge block 238 provide an adjustment great enough so that the adjustment of only one 105~

side of th~ movable doo~- panel 16 is normally required.
As shown, the ~edge having the flanges 240 and 242 thereon fits within the expander 124 ~-ith the inclined plane portion 24~ extending throu~h the slot 246 therein and with the Elanges 240 and 242 resting underneath ana on top of the ribs 248 and 250 in the expander 124, respectively. The wedge block 238 shaped as shown best in Figure 19 is secured to the side rail 46 by the screw 252 and ~x~ends within the bottom rail 42 with the inclined plane surface 254 in engag2ment wit~
the inclined plane surface 244. The adjusting screw 256 extends through the slot 258 in the side rail 46 of the movable aOo~ panel 15.
Thus, in operation, on ad~ustment of the position of the wedge 236 longitudinally in the expander 124, the side rail 46 of the movable door panel 15 is adjusted vertically to pivot the door p~n,el 16 in the plane thereo~ about the bottom of the locking side rail. The movable door panel 16 is thus adjusted relative to the expander 124 which carries the rollers 260 ~or ~ the movable door panel 16 and carries the weather strip member 122 on the side thereof. The movable door panel 16 is thus adjusted to me2t any o~t-of-squareness of the frame 12 ~ithout disturbing the rollers or the weather seal at the bottom of the ~, door.
In addition, the use o~ the e~pander 124 permits exchange of the movable ~oor panel 16 e~d for end to provide right and left hand operation by simply removin~ the expand2r 124 and the wed~e block 238 and placing them in the other Qnd of the movable door p~nel 16.

:

1()5~6Z7 It will also be noted that the adjustment of the movab.l~ door panel 16 i5 accomplished with a minimum number of parts in the simplest manner without disturbin~ the weather tightness or structu~al integrity of the movable door panel while preserving the lack of specific orientation of the movable door panel.
To providc a three-step, coarse vertical adjustment for the movable door panel 16, the wedge 236 may be positioned with the flanges 240 or 242 on top of ribs 248 or witll flanges 242 on top of ribs 250. Additional coarse adjustment could be provided by adding ribs intermediate ribs 248 and 250. In any position of wedge 236, fine adjustment of the edge o~ the door is accomplished by movement of the wedge 236 horizontal.ly with respect to the wedge block 238 with the inclined plane portions 244 and 254 th~reo:E in surface to sur ace engagement.
Adjustmant of the other ed~e of the mo~able doo.r panel 16 i5 possible with wedges and wedge blocks at both ends of :
expander 124.
Alternatively, the web 259 of rail 46 may be offset toward wedge 236 and used in place of wedge block 238 in con-junction with wedge 236 to provide adjustment of the edge of ` .
the mova~le door panel 16. . -: Another modification 262 of the-sliding door structure of the invention illustrated best in Figures 13 and 14 is simi-: ~ lar to the sliding door structure 10 and may in fact use an ex-terior frame 157 which is similar to the fra{~e 12 of the sliding door st.ructure 10 but may be of lighter and therefore more economical cross section. The head extrusion 155, jamb extrusions ' :~ .
. . .

1~5~ 7 264 and 266 and the sill e~trusion 268 o~ tlle frame 157 are thus substantially the same as the head, ja~b and sill men~rs.
oE the sliding door 10 as shown in Figure 13 except for the pxeviously consider~d tabs 151 and 152.
Similarly, the fixed and slid.ing panels 270 and 272 respectively are simil~r to door p~nQls 14 and 16. The cross section of the rail members is however altered as shown in Figures 13 and 14 to provide a lighter, more econor~lical and even more universal rail ma~ber. Thus, with the rail member cross sections illustrated in Figures 13 and 14, ~aximum strength per unit weight and maximum universality is provided to reduce inventory and thus cost of the sliding door structure.
As shown in Figures 13 and 14, the sliding door panels 270 and 272 utilize~the dual member glazin~ system previous.~y considered and illustrated in Figures 15-18 to secure the glaz-ing panels 274 and 276 in the door panels. The sliding door - structure 262 may utilize the mitered corner joints as illus-trated in Figures 27-29, the weathPr seal and prowler protection structure and bumpars illustratsd in Figure 7, the weather seal structure illustrated in Figures 4 and 9, and the top guides of Figures 10 or 11, along with the adjusting structure for the :~ movable door panel 272 as illustra~ed in Figure 12.
In the sliding door structure illustrated in Figur~s 13 and 14, the fixed door panel 270 is secured in position by screws passing-through the fins 278 o-E jamb.266 and fin 280 o head 155 in conjunction with an L-shaped bracket 282 secured between the fixed rail 284 of the fixed door panel 270 and sill 268 of the door structure 262.

~'. ' 105;~627 ' In addition, the modified door structure 262 of Figures 13 and 14 in ludes the unique screen door structure 286 illustrated in detdil in Figures 19-25. The screen door struc-ture 286 has been particularly designed for economy and efficiency of o~eration in conjunction with the slidin~ door structure 262 but is equally as economic~l and efficient in use with other sliding door structures such as sliding door struc-'ture 10.
As shown in Figure i9, the scree~ door struct~re 286 :~
includes a frame 288 having top and bottom rails 290 and 292 ./ . . . ., :
and'side rails~294 and 296. The s~reen rails have a cross section as shot~n best in Figure Z0 includL~g a first rectangular ~, portion 298 an& a second rectang~lar portion 300 separa_sd by a web portion 302. T~e rectangular portion,2~8 h~s a width trans-verse of the screen door structure 286 greater than that of the ~ectangular portion 300, which rectangular portion 300 has an open outer side 304'. , . . ',.
:, Also, the cross section of the screen rails as shown .
in Figure 20 includes an integral portion 306 in the shape of a parallelogram having one open side 308 which forms a recess in which the edge of the,screen member 310 is secured by an ~' H-shaped spline 312 having outer dim~nsions which define a parallelogram similar to the recess 314. The inteqral parallel-- ogram structure and the spline securing the periphery of the screen mem~er 310 to the ~rame 288 is illustrated.best in Figure 21.
. Such frame cross section is easily extruded and adapts itself to being connected with a pair of corner brackets 316 and ~'' ~ ' .

. . - .

~18 at each corn2r thercoE whereby tho fram2 2~8 is particularly sti~f. Such frame cross section also eli.minates the necessity for separate handle structure for opening and closing the screen since the screen can be moved by placing the fingers in th~ re-cesse~ formed on either si~e.o~ the web portion 302 of the cross section and applying pressure against either portion 29~ or 300 depending on the directior oE movement of the screen door 286 that is dssired.
The cross section of the rail mem~ers o the ~rame 2~8 further permits the use o a relativ~!ly simple loc~ing structure 320 with the screen door 286. The lo~king structure 320 in-cludes a bushing 322, a lockin~ member 324 having eam~ing beac~
321 thereon positioned adjacen~ one end of th~ buslling 322.and pivotally sQcured thereto by a pivot bolt 326. Ihe pivot bolt 326 extends throu~h the locXing member 324, the bushin~ 322 ~nd the jamb 264 of the sliding door structure 262. Thus, pivoting of the locking membsr 324 into and out of the recess provided between the rectangular portions 298 and 300 o~ the rail cross sections locks and unlocks the screen door 286 in a closed position.
Spring biased adjustable rolle.r assemblies 3~5 are provided in all four corners of the screen door structure 286 to adjust the screen door to sliding door frames which are not exactly square. One adjusting assembly 325 is shown in detail in Figures 22-25. The adjusting asse~bly 325 in~udes the : biasing spring 332, an.adjustable roller assel~bly 334, and an adjusting wedge 336.
As shown best in Figure 25, the adjustable roller ,~ :

": . , ' ` ' ' `

1~5~6~7 ~ssembly 334 includes a roller hous.in~ 338 having a hook 340 at one cnd thereof which is Eivotally engageable with a correspond-ing hook portion 342 on a corner bracket 316 to provide pivoting of the adjustable roller assembly 334 about the point 344 under urging of the bias spring 332.
In the roller assembly 334 illustrated in Figure 22, a hemispherical abutment 346 is provided on the roller housing 338 to limit pivotal movement of the roller assembly 334 out of the recess 348 provided i~ portion 300 of the top rail 290. In the modification of the adjustable roller assembly 334 illustrat~d in Figure 25, the pivotal movement is limited by the abutments 350 on the sides of the roller housing 338. In either case, the pivoting of the adjustable roller assembly 334 into the rec~ss 348 is limited by the flanges 352 on the bifurcated end of the roller housing 338.
Openings 354 are provided in the bifurcated end 356 of the roller housing 338 for receiving the inteyral axle portions 358 of the xoller 360 whereby the roller 360 is secu~ed in the roller housing 338 in alignm~nt with the slot 362 therein pro-duced by the bifurcation of the end 356 thereof. The tra~X 364 - of the frame head ex~rusion 157 is receive~ in the slot 362 of the adjustable roller asse~blies 334 in the top rail 290 of the screen 268, while the track 366 is received in the slot 362 in the adjustable roller asse~blies`in the bottom rail of the : screen 2~6.
The pivotally ad3usted position of the adjust~ble roller assembly 334 is also limited with respect to movement inward of the recess 348 by the adjustin~ wedge members 336 .`, ~ ` .
.

105~6~7 slid~ble alon~ ~e top and hottom rails of the scr~en 286 within the recesses 348. As shown best in Figure 24, the adjusting wedge me~ers 336 include the guide flanges 364 and the adjust-ing flanges 366 by which the wcdge members are guided and moved respectively in the recesses 348. Further, the wed~e members 336 are provided with notches 368 on inclined camming surfaces adjaccnt the adjustable roller assemblies 334, which notches provide points 369 for successively engagin~ a notch 370 in the roller housing 338 of the adjustable roller asse~lies on move-10 ment of the wedge mem2~ers 336 toward or away rom the adjustableroller assemblies.
With such spring biased adjustablc roller asse;l~lies, the actual roller 360 may be relatively small so that the open depth of the top and bottom rails need not be large, whereby a relatively strong frame may be produced with a minimum of material by a simple extrusion cross section.
In four-panel sliding door installa-tions, a portion of one of which is illustrated in Pigure 26, an astragal adapter 373 having the general cross section illustrated in Figure 26 20 and extending substantially the full length of the locking rails 375 and 377 of the two movable door panels in such ~our-panel door installations is secured to ona of the locking rails by-convenient means such as scr~ws and releasably receives the lock-ing rail of the other of the movable door panels. Conventional handle and locking structures~may be secured to the abutting locking rails and/or astra~al adapter.
With such structure, one of the usual sliding screen doors 286 is provided with an L-shaped base bracket 374 secured to --32~

105;~62~7 one of the abuttin~ locking rails 238. A bushing 37~ is posi-tioned with one end against the bracket 374. A locking member 378 is positioned against the other end of the bushing and is pivotally secured to the other end of the bushing by means of the pivot bolt 380 extending through the locking member 378 the bushing 376 and the base bracket 374. The operation of such locking structure 382 is similar to the operation of the locking structure 320.
With the sliding door structures lO and 272, it is often desirable to double lock the movable door panel or open it a few inches to provide ventilation and still maintain the movable door panel locked to prevent entry of prowlers or the like or to prevent small children from going out of the sliding ~ ;~
door. As indicated above, in the past such locks have not been provided on sliding door structure or have either been too complicated or not sufficiently sophisticated. Thus~ in the past a length of pipe which may be inserted between the frame ~amb and the free rail of the movable door panel of the sliding door structures has been used to prevent openiong of the movable door panel more than a predetermined amount.
In accordance with the present invention, a prowler lock structure 384 is provided as shown in Figure 31 which in-cludes a generally V-shaped member 386 having a notch 388 at the end of one leg thereof~ a tamplate opening 390 adjacent the apex thereof and an opening 392 in the apex thereof in which a stud 394 is secured extending on both sides of the member 396.
The stud 394 has enlarged headed portions 396 on the ends thereof. The prowler lock structure 384 has the elevation lOSZ~i27 configuration illustrated in Figure 31 and is substantially flat except for the stud extending therethrough as shown in Figure 32.
On installation, the prowler lock member 386 is posi-tioned with the top of one side of the movable door panel free sicle rail received in the notch 388. The notch 388 and the re]ative dimensions of the prowler lock member 386 together with the positioning of the movable door side rail in relation to the head of the sliding door frame is such that after installation, the prowler lock member 386 cannot be removed from the moving panel side rail without ad~usting the movable panel to its lowermost position.
After installation of the prowler lock member 3~6 on the side rail, the prowler lock member 386 is pivoted counter-clockwise about the top of the side rail portion within the notch 388 until the stud 394 on the prowler lock member 386 engages the fin of the frame head member, at which time a hole 398 is drilled through the template opening 390 in the ad~acent fin of the head member. Such holes are drilled wherever it is desired to lock the movable door panel.
In operation then, with the holes 398 drilled in the head fin and with the prowler lock member 386 positioned as indicated in Figure 31, the movable door panel may be completely opened and closed with the prowler lock member 386 serving no function. Nhen it is desired to lock the movable door panel in a position at which there is a hole 398, the prowler lock member 386 is pivoted counterclockwise so that the stud 394 aligns with the desired hole 398, after which the prowler lock member 386 is moved transversely outwardly of the sliding door structure to . ~ ~ . .. . : .

~ o5z~;z7 engage one end of the stud 394 in the selected hole 398. The `~
other end of the stud 394 may be used as a handle in accomp-lishing the alignment and movement of the prowler lock member ;
386. On release of the prowler lock member 386, the head por- -tion 396 on the end of the stud 394 within the hole 398 will prevent accidental removal of the stud from the hole and provide a positive lock of the sliding door panel in the -selected position.
In the modified prowler lock structure 400 illustrated in Figure 33, the prowler lock member 402 bas a side elevation as shown and again is generally flat except for a stud 404 extending transversely therethrough, which stud may have a head 406 on the side ad~acent the fin of the sliding door frame -~
head and may ha~e a nut 408 associated therewith which would serve as a handle on the opposlte side thereof, as shown ln Figure 34.
With the prowler lock structure 400 illustrated in Figures 33 and 34, again the prowler lock member 402 is posi-tioned over the end of the side rail by means of the slot 410 in which position the pro*ler lock member 402 may be moved up or down, as desired. Again, an opening through the prowler lock member 402 (not shown) may be used as a tamplate for drilling holes 412 in the flange of the frame head at the locations where locking is required.
In opera~ion, with the prowler lock member 402 in a down position, the prowler lock structure is not operative.
When it is desired to lock the movable door panel in a selected position~ the movable door panel is moved to the position , . . .

105'~6Z7 desired, thc prowler loc~ membec 402 is moved up and ~he stud :
404 is aligned with an opening 412, a~ter wllich the prowler lock membe:r is moved toward the fin of the fràme head to insert the stud 404 through th^ selected hole 412 and p~ovide a positive lock for the movabl~ door panel.
A third pro~ler lock struc-ture 414 suitable for use with the sliding door structures 10 and 262 and illustrated in Figure 30 includes the prowler ~ock lever 416 including the notch 425 therein adapted to receive the upper end of the moving panel Eree side rail. Lever 416 further has a projection ~18 on the end 420 thereof adapted to fit within openings 422 pro-vided in the sliding door frame head. The end 424 of the prowler lock lever 416 is weighted to bias the projection 418 into an opening 422 in the head. A further notch 426 is provided in lever 416 which i5 also adapted to fit over the top of the free side rail of the sliding door moving panel and thus retain the lever 416 in a stored position with the end 418 not biased into engagement with the sliding door frame héad as shown in phantom - in Figure 30.
ThuF, in operation of the prowler locX structure 41A, ~: with the top of the rail within notch 426 in lever 416, the ' .
movable door panel 16 may be moved to any desired location.
With the top of the-~free rail~of the sliding door panel in the notch 425 in lever 416, the projection 418 of the lever 416 will ; be biased into the first opening ~22 in the frame head that it comes to on sliding o~ the movable door panel in either direction to positively lock and movable door panel in a desired position.
In the prowler lock structure 450 illustrated in 105'~27 Figure 35, a member 452 having the elevation illustrated in Figure 35 and a width suitable for fitting within the frame head of the ~liding door structure over the movable door panel is secured to the head of the frame adjacent the free end of the movable door panel by convenient means such as screws (not shown). A flexible spring member 456 having the configuration shown in Figure 35 is positioned in the recess 458 and the locking member 460 is hooked over the rib 462 by means of the hooked end 464 thereof whereby the end 466 thereof will engage the free side rail of the movable door panel and prevent un-desired opening movement thereof.
When it is desired to open the movable door panel, the lock member 460 may be pivoted clockwise by insertion of a finger in the recess 468 after which the locked member 460 may be moved to the right in Figure 35 whereby the spring 456 maintains it in a hori~ontal position out of the way of the movable door panel. A reverse process may be used to move the `
lock member 460 into a locking position.
If desired, the ventilation stop 474 may be secured at the other end of the member 452 by the interlocking hook portions 476 and 478 thereon. In operation, the ventilation stop member 474 permits opening of the movable door panel only a desired amountjas, for example, six inches, to prevent entry of prowlers and undesired exit of small children, and the like.
As shown best in Figure 36, the frames 12 and 157 of sliding door structures 10 and 262 may be secured in a building opening 480 by means of nails passed through nailing strip adapters 482 interlocked with a rib 485 on the frame members lOSZ~27 where direct connection of the frame members in the building opening is not desired. The nailing strip 482 has the cross section illustrated in Figure 36 and may be of any desired length. Alternate nailing strips 484 particularly suitable for use with brick construction may have the configuration shown in Figure 37.
Further, the interior trim of the bullding opening ; 480 may be facilitated with a trim extrusion 486 having the cross section illustrated in Figure 36. While other building constructions are possible, in Figure 36 brick facing 488, interior stud 490, exterior wall 492 and interior wall 494 are illustrated. The joint between the frame ~amb and the interior trim extrusion 486 is closed as shown by a closure strip 494 having substantially lthe same configuration as the glazing ; member illustrated in Figure 16.
Also~ the interior trim of the building opening in which the sliding door structure is secured may be facilitated at the sill by means of the plastic bullnose extrusion 496 having the cross section shown in Figure 38 and adapted to fit between the inner sill flange and the interior flooring 498.
The bullnose extrusion 496 is flexible to permit varying dimensions of flooring to be used in con~unction with a standard sill.
A modification of the bullnose member 496 is shown in Figure 39 to accommodate thicker flooring such as carpeting as may be desired or to accommodate a lower inner flange on the frame sill. To-~this end, the extension 500 is provided on the bullnose interior trim member 502 illustrated in Figure 39.

~OS,'~:6Z7 Furhter, the sill may be extended by means of the adapted extrusion 504 having the cross section illustrated in Figure 38 and shown in con~unction with wood sub-flooring and masonry exterior building members 506 and 508.
The exterior trim member 510 illustrated in Figure 40 is unique in that it includes a relatively soft wood core 512 and an extruded shell 513 of relatively harder and/or more weather resistant material adapted to interloc~ with the sliding door frame as shOwn in conjunction with the frame ~amb. The trim member 510 may be secured to the usual exterior wood building wall by convenient means such as nails (not shown).
Interior trim may assume the configuration of extrusion 514 having the cross section shown in Figure 40 including the pocket 516 for receiving the end 518 of the frame jamb cross section and the flexible leg portions 520 and 522. Assembly of the interior trim strip 514 is as shown in Figure 40.
