S 1' E ( L 1` [ ~ A l l 0 N
Ihis applicatioll is a division of Serial No. 161,817, filed January 22, 1973.
The invention re:lates -to building s-tructures and refers more specifically to a sliding door which is esthetically pleasing, easily opera-ted, has weather-tight integrity to bo-th air and water, has extremely high s-tructural integri-ty and sub-stantial universality of componen-ts 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 ex-truded 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 formingthe mitered joints to each other. Thus, mltered joints in the past have required skilled workmen-t to produce and have often been misaligned.

In addition, in prior slidin~ door~ lth~3r two pock~ts formed by three ~in~, one pocket ~or each of a mov~hle and ~ix~d door panel with a fin between the door panels, have been provided in the frame he~d, or alternatively, three poc~ts have been pro-vided b~tween two out~r fins and two intermediate or guide fins in the frame head for guidin~ the top rails of a movable and a fixed - doo,r panel, with the guide fins received in slo~s in the door panel top rails. In both structures, considerable weather seal-ing and/or fabrication o~ weather seal interlocks on the door panels has been necess2ry. Again, the added weather sealing and fabrication together with the orientation which the fabrica-tion and/or weather sealing require has given the components of and the finished doox panels thus constructed has added an undesirable cost factor and inventory requirement to previous sliding doors.
Further, previous sliding doors have usually not been suitably weathertight without expensive and ~ometimes compli-cated structure. Thus, for example, a complete aluminum .: :
surround has often been provided in the past for glazing sliding door panels from the inside to prevent popping of the glazing panels out of the frame therefor under high wind 1oads.
Complicated struc-ture has sometimes been required to prevent entire sliding door panels from being blown out of the outer frame therefor.
In addition, with prior sliding doors, stopping of the slidîng door on opening has sometimes been a problemO
Wherein stops hav~ been provided only at the tops or bottonls of the movable door panel, the door panel tends to cock in the ~3 ; ~:

. ~. ... .

1~37~7 ~rame on hitting -the s-t~p, thus wearing door panel rollers and damaging the outer ~rame or movable door panel. Prior stop structures have in addi-tion also reqwired separate ~abricatlon of the frame member to install and sometimes themselves have been complicated and -therefore expensive. Central stops have in general not been utilized due 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.
Further, with prior sliding doors it has often been possible on jiggling the movable door panel to unlock it and to gain entrance into the building in which the doors have been installed. It has generally been impossible with sliding doors to lock the movable door panel in a partly open position to provide, for example, ventilation without allowing small children to go out or prowlers to come in the doors.
Also, it has been difficult in -the field, with the size ~ -of sliding doors usually installed today, to obtain square struc-tural openings for the sliding door structures. It has there-fore been necessary to adjust the movable door panel of sliding 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 entirely independent at both sides of the movable door panels.
The sliding screen doors provided with the sliding 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 .

'` ) ' '1~37~1q screen doors. The fr~ne members have thereEore o~ten been of dif~erent cross Scction and have not always been provided with mitered cornexs. In addition, in the past, screen members have been secured to the frames in rectangular rec~sses receiving either round or rectangular splines Such structure has not always securely held the periphery of the screen to the frame.
Se~arate handle and locking structures have usually been pro-vided with prior sliding screen doors.
Further, in the past, sliding doors have not always been adapted for instal~ation in a wide variety of building structures with a single frame, as for example~ building struc-tures which require nailing fins for securing the frame to the exterior of the building structure. In addition, neither ¦ interior nor exterior trim for sliding doors have normally been readily available and extensions of sliding door frame sills have in the past generally been field fabricated.
In accordance with the present invention, there is provided a sliding 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 of which is movable, which ~uter frame and door panels and the individual members thereo~ 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, wherever possible the members of the sliding door structure of the invention are interchangeable right-left, up-down, inside and outside.
In one modification of the preferred embodiment of ~, :~ .

" , , .
~. - . . . .

:~L0373~7 the inven~ion, the members o~ the ~rame and door panels have been constructed to provide a cross section which is ef~icient yet particularly economical.
The mitered corners o~ the outer ~xame are provided with integral o~fset abutment structure on one member thereof adapted to engage the o-ther men~er forming the corner, whereby the corners may be quickly and accurately aligned in assembly and tightly connected without the danger of misalignment on drawing the miter-cut members tightly against each other.
The structure of the mitered corners of the invention ~ -includes a pair of elongated members joined at one end of each of them, each o~ the members having a web portion from which flange portions extend perpendicularly thereto, which flange portions are ter~inated at one end of each of the members in a miter cut. The miter cut ends of the members are complementary so that the one ends of the members abut in a miter joint when `
properly aligned. The miter joint structure further includes means securing the one ends of the elongated members together including means for preventing misalignment of the elongated members on securing the one ends of the elongated members together comprising an offset portion in the web portion of one of the elongated members at the one end thereof, which offset portion includes an end which abuts the side of the web por-tion of the other elongated member adjacent the end of the one elongated memher at the one end of the other elongated member.
The method of the invention of forming a mitered joint includes the steps of offsetting a portion of one end of one of the members to abut the side of the other member at the one end thereof with the one ends of the members miter cut and in align-~ .
~ ~' ' .

~', ~ . ' ' ' ~'. ' : , , ~ 0373~7ment and securing the members together by fasteners extending transversely through the end of the other member at the one end thereof and longitudinally into the one end of the one member.
In another modification of the sliding door structure of the invention, the fixed door panel may be retained at its fixed 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.
A unique bumper system is provided for the sliding door structure including a resilient bumper at both the head and sill of the frame engageable with the sliding door panel which require no fabrication of the sliding door structure. In addition, prowler security means are provided at the upper corners of the sliding door structure which prevents upward jiggling of the movable panel and conse~uent unauthorized unlocking thereof along with weather stops at all four mitered corners of the sliding doors, which weather stops al~o ~erve to align the mitered corners in field as~embly. Separate prowler lock structure and modifications thereof are also provided to permit securing the movable panel of the sliding door structure in any of a plurality of closed and partly open positions.
To compensate for out-of-square door openings in ;

9.0373~7 inst~lla~ion, tll~ mo~ le p~nel of th~ slidin~ door is position~d on an ~pand~r ~nd a wed~J~ and a w~d~Je bloc~ are secur~d to the expander and to one edye of the movable panel of the sliding door structure respectively, having ~ngaged, inclined plane surfac~s fox pivoting the movable p~nel in the plane o~ the movable daor panel about one edge thereof. The wed~e is constructed to fit within the expander at two different levels to provide coarse mov~ble panel adjustment. Fine ad~us~ment of the panel is pro- ~
duced by relative movement of the wedge and wedge block. wedge ~ :
and wedge blocks may be provided at one or both edges of the movable door panel.
The sliding screen door of the sliding door structure ~ ;
in one modification is provided with rolled frame membsrs having a relatively deep cross section in the plane o~ the~.screen which is open at the outer edge of the screen at the top and bottom ;
rails to permit adjustment of adjusting rollers position~d therein at the four cornexs thereof. The periphery of a screen member is retained in the frame of the screen door ~y means of ~ ~:
a rectangular recess and round spline means positioned therein.
- In a more economical m~dification of the preferred ` A~
embodiment of the sliding door structure, the screen frame .
members are extrusions and are provided with unique spring loaded adjustable roller assemblies at all four corners thereof which do not requ.ire deep upper and lower rail cross sections.
The ~screen frame extrusions of this modification are also con-structed to eliminate the necessity of separate screen handles and to facilitate lockin~ of the screen to the sliding door structure outer fran~e by particularly simple lock s~ructure and ~ 7 :~

The ~irst modification o~ the preferred embodiment o~
I the sliding door structure 10 sho~m in Figure 1 includes an outer ~rame 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 pluralit~ of ~ixed and~or moving doo_ panels. Thus, the invention is not intended to be limited to sliding doors having a single ~ixed door panel and a single movable door panel.
As sho~n, the outer frame 12 includes ~ header or head extrusion 20, jamb ex~rusions 22 and 24 at o~posite sides of the - . ...... . .. ._ . b~

r ~ J ~ llL0373 ilL7 slidin~ door structure lO and a si]l extru3ion 26, ~Ihich ~xtrusions ha~e -the cross sect1On!3 best sho~n in Figures 2 and 3. Each of the four cornexs 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 ~ll four corners ; being mitered, the jambs are universal in that they have no left, right~ up or dot~n orientation.
To aid in securing the mitered corners of the frame j 12 together in the desired alignment, one or more portions 31 of the jambs 22 and 24 at the ends thereof are offset or de-pressed as shown best in Figure 28 to provide an end abutmen~
33 against which the side o~ the web 35 of the head 20 and a ! similar portion o~ the sill 26 are urged by the screw means 25 extending into the sc~ew runners 37 in the ja~lbs 22 ana 24 in assembly of the frame 12. With such structure, the mitered members at the ~our corners are not permitted to slip pa~t each other along the miter joint as might otherwise happen if the securing screw means 25 were drawn too tigh-t. The mitered cor--- ners of th~ frame 12 may thus be accurately constructed by relatively unskilled workmsn. 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 ~ixed door panel frame 28 having a top rail 30, a bottom rail 32 and free and fixe~ side rails 34 and 36 respectively, again havin~ th~ 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 shot~
best in Figure l and are secured to the top and botto~ rails 30 ~4 .. j .. . ..... . . . ..

:~L03P~317 and 32 at oppo~ite ends thereoE by suitablc means such as screT~Js or the likc. A glazing parleL 38 is secured in the fixed door panel frame 28. Each of the top, bottoln and side rails of the fixed door panel 1~ is also substantially universal in that they have as little orientation as possible so that the complc-te panel 14 as well as the individual men~ers thereo~ may b~ used for different sliding door confi~urations.
The sliding door panel 16 includes a top rail 40, a bottom rail 42 and loc~cing and free side rails 44 and 46, i 10 respectively. Also as before, the side rails 44 and 46 extend th~ full len~th of the movable door panel 16 and are connected ffl the top rail 40 and bottom rail 42 at the opposite ends --thereo~ as shown best in Figure 1. The ylazing panel 48 is secured in the movable door panel 16 as before and all o~ the-me~bers of the movable panel 16 are constructed without par-ticular ori~ntation when-possible SQ as to b-e interchancJea~le.
Thus, the sliding door structure 10 may be construct:ed in a great number of configurations with a minimum o~ separate par~s such as frame jam~s and panel rails and the like, and a complete inventory o sliding doors may be stocked, again w:ith a minimum of separa-te sliding door elements such-as exte.rior fr~mes, fixed ancl moving panel. The cost of a sliding door inventory and production equipment and facilities is thus reduced.
The screen structure 18 shown in Figure 1 includes the frame 50 having a top rail 52, a bottom rail 54 and SidQ rails 56 and 58~ A screen 60 is secured within the frame 50 by con-venient means such as a peripheral recess 62 in the rails havin~

1al3731~
screen retaining mem~ rs 6-~ pc~ ion~d ~h,~rein. Rolle,r~ 66 are mountcd in thc top arld bottom screen fram-e ~ails and run on tracks 68 and 70 in the frame head 20 and sill 26 as shown.
Suitable handle structure 72 and latch structur~ 7~ are pro-vided Eor moving the screen structure 18 in the plane of thc frame 12 and retaininy the scr,~ n in a closad position over the opaning provided by the movable door panel 16, respectiv?ly.
The head 20 of the door frame 12 has a cross section ~ ;
shown best in Figure 3 ~hich includes an outcr ~in 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 the outer fin 76 and ~he 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 docr panel 16 are positioned. A guidin~ fin 86 is further provicled in the pocket 84 for guiding the movable door panel 16 wlthin 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 f~brication of the interlocking poxtions of free side rails 34 and 46 is required and removable interlocking portions to facilitate universal orientat.ion 3f ¦~
the free side ra.ils is not required~ Similarly, since only the mova~le door panel 16 is provided with a guiding fin 8~, spec-ial weather stripping to prevent the passage of wind and water through the door s~ru~tur~ 10 between the head 20 and the top rails 30 and 40 is minimized and uncomplicated.
Thus, the fixed door panel 14 is providecl with an .~ '` .

1~1373~
elongated sealing m~mber 88 clt th~ ~op rail 30 havincJ th~ cross s~ction ~ho;~l be~t in Flgure 3. Th~ s~alin~ m~mber 88 per~orm~
the dual function o~ providing structurtl'int~grity at the top of the fi~ed door panel 14 between the head 20 and the top rail 30 and seals the top of the fixed cloor panel. As shown, thF
-- 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 tha 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 1~ and as shown best in - Figure-3 includes a portion fitting over o~e ~i~e portion oE
: :-- the bot~om of the bottom.rail 32 of..the fixed door panel 14. , - ~ :-' and anoiher portion fitting over the rib.92 on the frame sill ~' -~ :26.. - Again, the sealing member 90 provides structur.al integrity - --~-between the frame 12 and fixe~.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 Ittay be used in place of th~ sealing member 90 When the sealing membe~ 94 is-used, the str.~ctural integrity - - of-the fixed door panel 14 at the bottom is provided primaril~ :
by-the weight of the door panel 14 resting on the sill 26 bet~een the ribs 92 and 96. The me~ber 94 functions primarily as a weather seal.
The sealing of the fixed door panel 14 between the fixed side rail 36 and the frame 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 ja~

~7 ~ t ., ' ' ' ., ' ' ' ' ' 7~7 ~4 as 3hown best in Figur~ 2. In addition, th~ struc~ural integrity of th~ ~ide rail 36 w;ith the jamb 2~ is maintained by the staked-out portions 102 of t:he sid~ rail 36 fitting behind the returned ~nd portion o~ tho fin 104 of the jamb 24.
If desiredJ the side rail 36 may be secured to the ~amb 24 by separate screws, clips or the like in keeping with present conventional constructionO --In asset~bly, the sealing mer~bers 88 and 90 or 94 are ~:
positioned on the fixed door panel 14 and the door panel 14 is tO positioned in the frame 12 by first placing the fin 80 in the ! seal 88 and pivoting the-fixed ~oor panel-14 inwardly of the frame 12 at the bottom while moving thè flxed-door panel-14 j 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: aoor panel 14 is allowed ~o drop vertically sliyhtly to - position the seal 90 or 94 over the rib 92.
I The fixed door panel 14 is then moved toward the frame jar~b 24 to cam the staked-out portions 102 of the side ~ ~.
rail 36 of the fixed door panel 14 into the jamb pocket 106, ~ .:
_ whereby the sealing strip 98 is positioned in contact with the fin 100 of the jat~b ~4 and the fixed rail 36 is locked in assembly with the jamb Z4. Removal of the fixed door panel 14 then requires the placing of a screwdriver or the like between the fin 104 and rail 36 to spring the fin 10~ and permit the staked-out portions 102 of the rail 36 to be removed from the jat~b 24. Such retnoval of the fixed door panel can only be accomplished from the inside of the-door.
- The fixed door panel 14 and the movable door panel 16 .. 1~

are sealed at the :inter:Locl~ing portions of` the ~ree sidc rails thereof by the :flexible str:ips 108 ancl 110 positioned in -the side rails 34 and ~16 as shown best in Flgure 2. Similarly, -the locking side rail 44 of the movable door panel is seale~ in the pocket 112 of frame jamb 22 wi-th the movable door panel 16 in a closed posi-tion by the flexible strip 114. S-trips 108, 110 and 114 may be vinyl, felt or similar ma-terial. As shown, a suit-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 bes-t 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 side 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 .... . . . .

~3'7~7 pliable por-tion 13'~ of the sealirlg member wipes aga:inst the ~pper rail 40 o:f the movable door panel 16 -to provide a seal -therefor.
Thus, both -the fixed door panel 14 and the movable door panel 16 are comple-tely 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 again 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 members 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 " " ; ! ' ' .i ~` . ~a~373~7 j secured by a screw to the fin 80 of the head 20 adjacent the frce side rail 34. With such a~dit:ional structure, the sliding ;l door structure 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 1440 The member 144, which is shown in perspective in Figure 8, includes the triangular fin portion 146 adapted to complete the guide fin 86 o~ the head 20. The 10 fin 146 is necessary du~.to the ~itered corner and the provision ~f the fin 86 on the.head 20 without a similar fin on the jamb .. .. .. ..
members 22 and 240 .~I~ addi~ion, 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 pocXet 112 by the projections. l52.and 154 thereon. The flanges 156 and 15B aid in retaining the member 144 in position at the top of the jamb members 22 and 24 with the upper portion of the fin 86 in the slot 160 between the portions 148 and 150. When i.n-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 serv~s to prevent upward jiggling.of the movable door p~el 16 and consequent unlocking D~ the latching mechanism by prowlers or the liXe. Thus, witl the movable door panel 16 closed, the top of the locking side rail 44 will engag~.the bottom side of the portions 148 and 150 to prevent undesired upward movement thereof.

A similar function m~ay be accomplish~cl ~y cut-out an~
; folded-do~ rectc~ngular portions such as portions 151 and 153 in the head 155 o~ the frame 157 sho~1 in Figure 14. Such cut-out and folded-down portions may be provid~d an~he~e along ~he length of the head 157 where they are desired, but will most usually be spaced out across the opening provided in the sliding door structure by the open movable door panel.
Bumpers 164 as sho~m 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 cocking of the movable door panel 16 which might occur on-eng~gement o~ the movable door panel with a single bumper 164 at either the head or sill of the frame 12. Thus, separate stop membexs 1~4 are positioned both on the rib 130 of the head and on the track 166 of the slll so-that-they engage the free rail 46~ of the movabIe door panel 16 as the door panel approaches a ull~ 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 `
head 20 or sill 26 is necessary to install the bumpers 164.
- The triangular membar 168 is provided at ths bottom o .:
the frame iambs 22 and 24 to close the bottom o~ the mitered ~`

The glazing members 174 illustrated in Figur~s 1-3 can withstand lligh wind loads on t:he glazing panels 38 an~ 48.
However, such channel type glaz.ing is expensive and requires that the panels be removed and disasser~led for reglazing.
Therefore, since interior gl~zing of sliding doors is desirable, as for example in apartment buildings and the like, door panel top, bottom and side rails haviny a glazing cross section con-figuration such as that illustrated in Figure-15 including th~
recess 176 are-provided. Such rails in conjunc~ion with the glazing members 180 and 182 or 184 illustrated in Figures 15 and 16 provide..a very high wind re~sistant glazing system which may be installed from the inside of the sliding door and will accommodate substantially the full range of glazing panel thicknesses from thin, single strength to thicker insulating . ~
gl~ing panels at a moderate cost. ~.
Wlth the glazing system illustrated in Figure 15, a glazing panel such as panel 186 is positioned in the door panel opening against ths glazing flange 188. The glazing member 180 having the L-shaped 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 me~ber 182 or 184, depending on ~ ' .
the thickness.o the glazing panel 186, is inserted between the ~lazi.ng pan21 186 and the portion 192 of the glazing member 180 with the projecti~n 1~4 on -the memb~r 180 extending within the recess 1~6 in the member 182 or 184. -.

~ The modified glazing member 191 as shown in Figure 17 ~3 I

3~3~L7 is a dual durom~t~r m~mb~r having a relat.ively hard portion 193 similar to thc h-sh~p~d cJlaæing member 1~0 and a relatively sof~ :
portion 195 similar to the glazing m~mber 182. ~he portions 193 and 195 of the glazing member 191 are connected by the r01ativ~1y soft, flcxible portion 197. In installation, kha L-shaped por~
tion 193 of the glazing member 191 is installed in the recess 176 in the rails of a door panel and the portion 194 is rota~ed counterclockwise into the position sh~wn for glazing member 182 in-Figure 15-. The advantage of the dual durometer gla~.ing ;, member 191 is a savin~ in-extrusion time, since only one extru-slon need-~e made, and in cutting and assembl~ time, since only one g~azing member 191 need be cut to length and handled.
The modified dual durometer glazing strip 19~ illus-trated in Figure 18 has a relatively hard, L-shaped portion 201 : :
and the relatively so~t portion 203 connected by a frangible portion 205o In assembly of the glazing me~bex 199~ the 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 movament of the sliding door panel along the guide fin 86 without galling the guide in 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 shown best in Figure 10 is provided. The top `guide 200 is provided with a hairpin shaped portion 20Z which --fits within a slot 204 in the upper end of the side rails 44 and 46 of the movable door panel 16 as sho~m in Figure 3. The , hairpin shaped portion 202 of the top guide 200 includes a slot 206 in which the guide fin 86 is slidably received and a `j~ 2~ .

~ ~373~7 ~lan~e 208 which ~ids in securing the men~er 2ao in thc slot 204. The top g~lide 200 is provided with the extension 210 having the spacing struc-ture 212 on the ends thereo whereby with the top guide 200 in position at the ends of the top rail ~V, ihe slot 206 is position0d centrally of the top rail~
: A modi~ied moving panel top guide 2~4 is illustrated in Figure 11. The structure 21~ is again provided with a hair-pin portion 216 for receiving the fin 86 and adapted to be held within the slot 204. A ~lexible extension 218 is prov.~ded on one side of the'hairpin portion 216 which engages the side of ~he'~guide`fin'86:'in assembly and-prevents-~ gIlng of the mov-ab~e door panel 16 transvarse of th~ door panel in operati~n.
With the larger size sliding doors today, it is un- ~.
usual to ind a building opening for a door which is exactly :
square~ Thus, adjustment of the movable door panel 16 is normally required to provide a desired it within the frame 12, the members o which are secured in the ~ullding opening and to some extent follow the irregularities of the bu~lding opening. ~ ~
The structure shown in Figure 12 provides adjustment .. ' of the moving door panel 16 by pivoting the moving door panel about ~he bottom of the locking rail on vertical adjuscment o~
- the-~ree rail side thereof. The ad~ustment of the movable door panel 16 is accomplished through the use of expander 124, a ' wedge 236 adaptea to it within the expander 124, and a wedge ' ;~;
~ b~oc~'238's~ecured 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 biock 238 provide an a'djustment great enough so that the adjustment of only one 2~ .

side of the movable doo~ pane.l 16 is normally rcquir~d.
Aq shown, thc wcd~e havin~ t~.e flanges 240 and 242 thereon fits within -the expander 1.24 with the inclined plane portion 244 extondin~ th ough the ~lot 246 therein and with th~ flanges 240 and 242 resting underneath and on top of the ribs 248 and 250 in the expander 1:24, respectively.. The wedge block 238 shaped as shown best in :Figure 19 is secured to the ~ide rail 46 by the screw 252 and extends within the bottom rail 42 with the inclined plane surface 254 in engagement with -10 the inclined plane surface 244, The adjusting screw 256 :- :

.. ~hus, in operation~ on adjustment of the ~osition of ;.
the wedge 236 longitudinally in the expander 124, the æide rail ; . .~ ,, 46-of the movable door panel 16 is adjusted vertically to pivat the door panel 16 in the plane thereof about the boktom of the .
locking side rail. The movable door panel ~6 is thu~ adjusted relative to the expander 124 which carries the rollers 260 for -:
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 meet any out-of-squareness of the frame.l2 without .disturbing the rollers or the weather seal at the bottom of the door.
. In addition, the use of the expander 124 permit~
- - .
¦ exchange of the movable door panel 16 end for end to provide right and left hand op~ration by simply removing the expander 124 and. the wedge block 238 and placing them in the other end of the movable door panel 16.

., . ~ . ' ~03 73~L7 I It will also be noted thak the adju~tment o~ the movable door panel 16 i5 acconlp~ishcd with a minimum numb~r $ of parts in the simplest manner wi-thout disturbing thc weather tightness or structural integrity of the movable door panel while preserving the lack o~ specific orientation of the movable door panel.
To provide a three--step, coarse vertical adjustment ~or the movable door panel 16, the wedge 236 may be positioned ~, with the ~langes:240 or 242 on top of ribs 248 or with flanges f 10 242 on top of ribs 250~ Additional coarse adj~stment could be provided by adding ribs intermediate-ribs-248`and ~50.- In any i positlon of wedge 236, fine adjustment of ~he~edge of the door is accomplished by movement of the wedge 236 horizontally with . respect to the wedge block 238 with the i~clined plane portions 244 and 254 thereof in surface to surface engagement. ..
~ Adju~tment o~ the other edge-of the moYable door panel 16- is possible with wedges and wedge blocks at both ends of expander 124~
. Alternatively, the web 259 of rail 46 may be of~se-t , toward wedge 236 and used in place o~ wedge block 238 in con-junction with wedge 236 to provide adjustment o~ the edge of . the-mo~able door panel 16. - ~ -- --Another modi~ication 262 o~ 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 ~act use an ex-terior frame 157 which is similar to the frame 12 of the sliding ~oor structure 10 but may be of lighter and therefore more economical cross section.

- 5imilarly, the fixed ancl slidin~ panels 270 and 272 respectively ar~ similar to door panels.14 and 16. The cross section o~ the rail members is however altered as shown .in Figures 13 and 14 to provide a lighter, more economical and even more universal rail memberO Thus~ with the rail member cross sections illustrated in Figures.13 and 14, ~aximum strength per unit weight and maximum universali.ty~i~.provided to reduce : .-~

- --As shown in Figures 13 and 14, the sliding door panels 270 and 272 utilize the dual member glazing system previously 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 weather seal and prowler protection structure and bumpers illustrated in Figure 7, the weakher seal s~ructure illustrated in Figures 4 and 9, and the top guides .
of Figures 10 or 11, along with the adjusting stxucture for the mo~ble door panel 272 as illustrated in Figure 12.

In addition, the mod.ifiecl door structure 262 of F.igures 13 arld 14 includes the uniquc screen door structure 286 illustrated in detail in Figures 19 25. The screen door struc-ture 286 has been particul~rl~ des:igned for economy and efficiency of operation in conjunction.with the sliding door structure 262 bu-t is equally ~s economical and efficient in use with other sliding door structures such as sliding door struc~
ture 10~
As shown in Figure.l9, the screen door structure 286 .
includes a frame 288 having top and bottom rails 290 and 292 and side rails 294 and 296. The screen rails have a cross sectio~ as shown best in Figure 20 including a ~irst racta~gular .. . . . . . .. . . ~ .
portion 298 and a second rectangular portion 300 separated by a web portion 302. .The rectangular portion 298 has a width trans-. :
verse.of the screen door structure 286 greater than that of the rectangular 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 includss an integral portion 306 in the shape o~
20 - a parallelogram having one open side 308 which forms a recess in which the edge o~ the screen member 310 is secured by an H-shaped spline 312 having outer dimensions which de~ine a parallelogram similar to the recess 314. The integral parallel-ogram structure and the spline securing the periphery o the screen member 310 to the ~rame 288 is illustrated best in ~ ~.

S~h f.~a~e cross sectiorl a.l.so eliminates th~ necessity for se~arate handle structure for opening and closing the scr~en since the screen can b~ move~ by placing the ~ingers in the re- -cesses for~d on either side of the web porti~n 302 of the cross ~- ;
section and applying pressure agalnst either portion 298 or 300 ~-depending on the direction o~ movement o~ the screen door 286 that is desir~dO
The cros~ section of the rail members o~ the frame 288 further permits the use of a relatively simple locXing structure 320 with the screen door 286. Th~ locking structure 320 in-cludes a bushing 322, a locking member 324 having camming beads .
321 thereon positioned adjacent one end of the bushing 322 and .
. . . . : :..: .
. pivotally secured thereto by a pivot bolt 326. The pivot bolt 1 326 extends through the locking member 324, the bushing 322 and the jamb 264 of the sliding door structure 262~ Thus, pivoting of the locking member 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 adjustahle roller assemblies 325 are provlded in all four corners of the screen door structure 28G
to ad~ust the screen door to sliding door frames which are not ¦ exactly squareO One adjusting assembly 325 is shown in detail ¦ in Figures 22-25. The adjusting assembly 325 includes the biasing spring 332, an adjustable roller assem~ly 334, and an adjusting wed~e 336.

asscl~bly 33~ includes a rollcr hou5ing 338 having a hook 3~0 at one end th~of which is pivotâlly ~ngageable with a corraspond-ing hook portion 342 on a corncr bracket 31~ to provide pivotin~
of the adjustabl~ roller assembly 334 about the point 344 under urging of the bias spring 332.
In the roller assembly 334 illustra-ted in FigurQ 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 in portion 300 o~ the top rail 290. In the modification of the adjustable roller assembly 334 illustrated 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 recess 348 is limited by the ~langes 352 on the biurcate~ end o~ the ~ :
roller housing 338.
Openings 354 are provided in the b;.furcated end 356 of the roller housing 338 for receiving the integral ax1e portions 358 of the roller 360 whereby the roller 360 is secured in the roller housing 338 in alignment with the slot 362 therein pro-20- ducea by the bifurcation o the end 356 thereof. The track 364 of the frame head extrusion 157 is received in the slot 362 o~
the adjustable roller assemblies 334 in the top rail 290 o~ the screen 268, while the track 366 is received in the slot 362 in the adjustable roller assemblies in the bottom rail o~ the screen 286.

A.; sho~ best in Figure 2~, the adjusting wedge members 336 include the guid~ flanges 364 and the adjust- -ing flange_, 3i6 by which the wedge members are guided and moved respectively ln the reccsses 348. ~urther, the wedge members 336 are provided with notches 368 on inc1ined camming suraces adjacent the adjustable roller assemblies 334, which notches pro~ide poin,_s 369 for successively engaging a notch 370 in the rol~er housing 338 of the adjustable roller assemblies on move- -10 ment of the wedge members 336 toward or away ~rom the adjustable roller assemblies.
¦ With such spring biased adjustable roller assemblies, ~ : :
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 rela~ively strong frame may be produced with a minimum o material by a simple extrusion cross section.
In four-panel sliding door installations, a portion of one:of which is illustrated in Figure 26, an astragal adapter :~.
373 having ~he general cross section illustrated in Figure 26 20 and extending substantially the ~11 length of the locking rails 375 and 377 of the two movable door panels in such four-panel door installations is secured to one of the locking rails by convenient. means such as screws.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.

one of the abuttinq l~k~g rQils Z38. ~ bu.shing 376-is posi-tioned with Otle end a.3ainst the bracket 374. A locking member 378 is positioned again~-t the other end of -the bushing and is pivotally secured to the othex end of the bushing ~y means of the pivot bolt 38~ extending th.rough the locking member 378, the bushin~ 376 and the ba~e bracket 374. The operation of such locking structure 382 is similar to the operation of the locking structure 320.
- With the sliding door structures 10 and 272, it is :
10 o~ten desirable to double lock the mova~le-door pane-l or open a few inches to-provid~ ven~ilation-an.d stil~ a~ntain the m~able doo~ panel locked to prevent entry o prowlers or the like or to prevent $mall children from ~in~ out o~ the sLiding -door_ As indicated above, in.the past such locXs have not been provided on sliding door str~cture or have either been too .complicated or not suf~iciently sophisticated~ Thus, in the past a length of pipe which may be inser~e~ between the frame jamb and the ~ree rail of the movable door panel of the sliding '':
door structures has been used to prevent opening o.f the movable door panel mor~ than a predeter~ined 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 ths :end of one.leg thereof, a tamplate opening 390 adjacent the apex thereof and an opening 392 in the apex thereaf in which a stud 394 is secured extending on both sides of the member 396. `~
:The stud 394 has enl~rgad headed portions 396 on the ends -theroof. The prowler lock stxucture 384 has the elevation ;

,373~L7 configuration ill~stratacl in Fi~ure 31 and is substan~ lly ~lat except for the stud extending there~hrough 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 ree side rail received in the notch 388. The notch 388 and the relative dimensions o~ the prowler lock me~ber 386 togekher with the positioning oE the movable door side rail in relation to the head o~ the sliding door frame is such that after installation, the prowler lock member 386 cannot be removed from the moving panel side rail without adjusting the movable panel to its lowermost position. - ~ ~ -¦ After installation of the prowler lock member 386 on the side rail, the prowler lock member 386 is pivoted counter-clockwise about the top o the side rail portion within the ;~
notch 388 until the stud 394 on the prowler lock member 386 engages the fin of the ~ra~e head member, at which time a hole 398 is drilled through the template opening 390 in the adjacent -`
fin of the head member. Such holes are drilled wherever it is desired to locX 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 movahle door panel may be completely opened and closed with the prowler lock member 386 serving no function. When it i5 desired to lock the movable door panel in a position at which there is a hole 398, the prowler lock member 386 is pivoted counterclock~wise 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 ~.. . .. . . .
