Filed Oct. 1, 1963, Ser. No. 312,910 12 Claims. (Cl. 16S-103) This invention relates to a closure construction of the sliding type adapted for exterior walls of buildings and relates more particularly to a novel combined operator and latch for, as an example, a metal Window or the like. The operator and latch or locking handle of the present invention is operatively connected to the ventilator or sliding closure panel of the window for moving the ventilator horizontally in the opening of the frame to open and close the window.

The window includes a frame having a horizontally movable ventilator or sliding closure panel therein as well as a iixed closure panel. The sliding closure panel is positioned at the outer side or exterior of the frame when the frame is installed in the opening of a building structure and the iixed closure panel is positioned towards the inner side or interior of the frame in relation to the sliding closure panel. An insect screen panel closes the opening which remains when the ventilator is in an open position. lt is desirable to position the screen panel between the inner stile of the ixed closure panel and a jamb member of the frame, with the screen panel being located on the inner side of the iixed closure panel adjacent the interior of the building structure.

With such a construction the Vfixed closure panel is located in a plane intermediate the sliding closure panel and the screen panel. The screen panel overlies the sliding closure panel when the sliding closure panel is in a closed position. It is desirable to operate the sliding closure panel from the interior of the building and it is also desirable to accomplish this purpose without removing the screen panel. The window is of a design which prevents insects or dirt from entering the interior of the building structure through openings which are required for the operating mechanism for the sliding closure panel.

The window is designed for weather resistance and tightness in general and is further designed to prevent insects and dirt from entering the interior of the building structure when the sliding closure panel is in an open position. It is also important that weather tightness be achieved by a construction which can be shipped in knockdown condition and accurately assembled at the job site with minimum labor and time. Prior sliding windows have been proposed to meet this requirement but have r been accompanied with certain disadvantages with respect to assembly, tightness, proper adjustment and attractiveness of the window. Other disadvantages relate to the location of the weatherseal strips or elements and their relation with respect to the operator of the sliding closure panel. i

It is an object of the present invention to provide a sliding closure construction which comprises a frame adapted to be installed in the opening of a building structure, a fixed closure panel, a sliding closure panel, and a screen panel movable in the opening of the frame, with the sliding closure panel being located in the frame adjacent the exterior of the building structure and the screen panel being located in the frame adjacent the interior of the building structure, the bottom of the screen panel being spaced vertically above the frame sill, -a longitudinally extending upstanding rib on the frame sill between and laterally spaced from the screen panel and the sliding closure panel, resilient weatherstrip means interposed between the bottom rail of the screen panel and the rib to close the lateral space between the screen panel and the rib to prevent the entrance of foreign matter into the interior of the building structure through said lateral space, and an operator operatively connected to the sliding closure panel and extending laterally therefrom t0- wards the interior of the building structure across the top of the rib and through the lateral space between the rib and the screen panel to engage and compress the weatherstrip means in Contact therewith and through the vertical space between the screen panel and the sill member.

Another object of the present invention is to provide a sliding closure construction of the aforementioned type wherein the operator terminates in a handle located on the interior of the building structure, said operator being movable longitudinally through the space between the screen panel and the frame sill to open and close the sliding closure panel, said weatherst-rip means being in sealin g engagement with the movable operator at all times.

Still another object of the present invention is to provide a sliding closure construction of the aforementioned type wherein means is provided which is operatively connected to the operator and engageable with the frame sill for locking the sliding panel when in a closed position in the frame.

A further object of the present invention is to provide a structure of the aforementioned type wherein a com bined operator and latch is provided for moving the sliding closure panel without removing the screen panel.

A still further object of the present invention is to provide a window of the sliding type which has a combined operator and latch operatively connected to the ventilator, with the `operator passing beneath the screen panel without leaving an opening for the entrance of insects or dirt. This is accomplished by means of the weatherstrip means ymentioned previously.

Another object of the present invention is to provide a structure of the aforementioned type wherein a cornbined lock and Ioperating handle is provided which will hold the ventilator in partially opened positions.

Still Aanother object of the present invention is to provide a novel sliding window construction of exceptional weather tightness when the ventilator is closed and which is designed to prevent the entrance of insects and dirt when the ventilator is opened.

It is thus another object of this invention to provide a simplified low cost structure of the aforementioned type having certain advantages contributing to efficiency, reliability and long life as well as ease of maintenance.

Other objects and features of the invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawings.

Referring to FIGUREl l of the drawings, the window or closure of the sliding type is designated by the numeral 20 and comprises a frame 22, a iixed closure panel 24, a screen panel 26, a combined locking and operating handle 28, and a movable ventilator or. sliding closure panel 30 which is best illustrated in FIGURE 6. FIGURE 1 shows the side of the window 20 that faces the inside of a building structure. When reference is made to the window 20 the inside or interior will refer to the side of the window 20 at the room or inside of the building structure and the outside or exterior will refer to the side at the exterior or weather side of the building strncture.

The frame and closure panels preferably are fabricated from aluminum extrusions. The frame 22 has a vertical jamb member 32 on the side adjacent the ventilator 30', a vertical jamb member 34, a horizontal head member 36 and a sill member 38. The frame members are held together at the corners .by screws indicated at 39 as is conventional in the art.

The jamb stile 40 of the tixed closure panel 24 projects into an elongated recess 42 (FIG. 6) of the jamb member 34. A weatherstrip 44 prevents the entrance of air and moisture around the opening. The top rail 46 of xed panel 24 projects into a recess 48 provided in the head member 36 of the frame 22 as best illustrated in FIGURE 7. A weatherstrip 49 projects into the opening. The horizontal bottom rail S of fixed panel 24 sets on the sill member 38 (FIG. 2) and is positioned and held in place laterally by the upstanding elongated ribs 51 and 52 (FIG. 4) which are provided on the sill member 38. The ribs 51 and 52 extend across the entire length of the sill member 38. The vertical meeting rail or inner stile 54 of fixed panel 24 has an extending portion 56 retaining a weathervstrip 58 as best illustrated in FIGURE 6. A pane of glass 60 is held in place in the xed closure panel 24 by the resilient retaining strip 62. The retaining strip 62 extends around the periphery of the glass. Screws indicated at 63 hold the stiles and rails together at the corners as illustrated in FIGURE 7.

The ventilator 30 positioned at the exterior side of the lframe 22 moves longitudinally from the closed position to the open position represented by the dotted lines 70v as best illustrated in FIGURE 6. A resilient bumper 72 limits the movement of the ventilator 30. The bumper V72 is held by the bracket 74 that is attached to the sill member 38 by the screw 76. The meeting rail or inner stile 80 of the ventilator 30 has an extending portion 82 that meshes with portion 56 of the inner stile 54 of the xed panel 24. The weatherstn'ps 84 and 58 combine to form a weather tight joint between the meeting rails or inner Stiles when the ventilator 30 is in a closed position. The portions 56 and 82 are cut away as indicated at 86 in FIG. 7, to clear the projecting portion 88 on the ylie-ad member 36.

The top rail 90 (FIG. 7) of the ventilator 30 extends into a recess 92 of the frame 36. Weatherstrips 94 and 96 provide a seal. The jamb side member or inner stile 98 of the ventilator 30 extends into a recess 100 of the jamb member y312. A resilient bumper 102 limits the movement of the ventilator 30` in the closed position. Weatherstrips 103 provide a seal.

The horizontal bottom rafil 104 extends between the meeting rail or inner stile 80 and the jamb stile 98 of the ventilator `30 as illustrated in FIGURE 3. The width of the bottom rail -4 is dimensioned to have a snug tit in between the

walls

106 and 108 of the jamb stile 98 as best seen in FIG. 3. The bottom rail 104 also tits in the meeting rail or inner stile 80 and the top rail 90 lits in the Stiles 98 and 80 in the same manner to form the corners of the ventilator. Screws indicated at 110 and 112 in FIGURES 4 and 7 hold the panel members in place. A pane of glass 1v14 is held in the ventilator 30 by the resilient strip 116. The strip extends around the periphery of the glass.

A pair of rollers 120 rides on the rail 122 and supports the ventilator 30 while moving from open and closed positions. The rollers 120 are attached to the bottom rail 104 by brackets 124. Rail 122 is an integral part ott` and extends longitudinally along the sill member 38.

To move the ventilator 30 on the track 122 and lock the ventilator 30 in a closed position the combined latch and operator 28 is provided. The operator 28 has an elongated bracket that extends from the ventilator 30 inwardly beyond the screen 26. A handle 132 allows for locking and operating the ventilator 30 without removing the screen panel 26. The handle 13-2 is connected to the bracket 130 by the

links

134 and 136.

A dovetail shaped plate 138 is attached to the ventilator 30 by screws 140. The plate 138 is positioned at an intersecting corner of the ventilator 30, with the screws 140 passing through the

walls

106 and 142 of the bottom rail 104 and the jamb stile 98 respectively. The plate 138 has a tight sliding tit in a matching groove 144 in the portion 146 upstanding at the end of the bracket 130. A screw 148 secures the Abracket 130 to the plate 138.

A detachable sill 150 has ribs 152 and 154 that engage the elongated ribs 51 and 52 respectively provided on the sill member 38, to hold the detachable sill 150 in place laterally. The detachable sill 150 extends longitudinally between the jamb member 32 of the frame 22 and the meeting rail or inner stile 54 of the fixed closure panel 24. Screws 156 hold the detachable sill 150 in place on the sill member 38. A strip 158 attached to the wall 142 of the bottom rail 104 provides a continuous surface across the length of the ventilator 30 for the weatherstrip v160 to bear against.

An upstanding rib 162 which is best illustrated in FIGURE 4 is positioned on the detachable sill 150 so that the side surface 164 is offset from the surface 166 of the recess 168 provided in the jamb member 32 in a direction away from the screen panel 26. The screen panel 26 is positioned at the interior side of the frame 22. Surface 164 is also offset from the surface 170 of the inner stile 54 in a direction away from the screen panel 26.

The bracket extends underneath the horizontal bottom rail 172 of the screen panel 26 and lthe portion 174 passes upwardly between said bottom rail 172 and the rib 162 closely adjacent the surface 164. Portion 176 slopes downwardly and horizontally to join portion 146. Portion 178 connects

portions

174 and 176 to form a grove or downwardly opening slot 180 that receives the rib 162 as best illustrated in FIGURE 4.

Weatherstrip 182 is of the type having flexible pile 184 that is attached to a strip 186. The strip 186 ts in the slot 188 provided in the bottom rail 172 of the screen panel 26. The pile 184 is of a width suicient to span the space between the surface 190 of the bottom rail 172 and the surface 164 or the rib .162. The pile 184 has a density su'lcient to obstruct the passage of insects and dirt through the lateral opening between the aforesaid surface 190 and surface 164. The density of the pile 184 also allows the pile 184 to iiex and to be compressed between the surface 190 and the surface 166 of recess 168 and the surface 191 and surface 170 of the inner stile 54 as best illustrated in FIGURE 6.

As the operator 28 moves the ventilator 30 to open or closed positions, the portion 174 of the bracket 130 passes through the pile 184 flexing and compressing the pile 184 between the surface 190 of the screen 26 and the surface 192 of the bracket 130. After the bracket 130 passes by, the pile 184 restores itself to the extended position closing the lateral opening between the surface 190 and the surface 164 of the rib- 162 thereby keeping and maintaining the opening closed at all times.

The jamb stile 196 on the screen panel 26 extends into the recess 168 of the jamb member 32 and weatherstrip 198 provides a seal which closes the opening 200. The top rail 202 of the screen panel 26, as best illustrated in FIGURE 7, extends into the recess 204 of the head member 36 and weatherstri-p 206 seals the opening 208.

Weatherstrips

198 and 206 can be omitted when the screen rail and stile members are held against the rib 209 of the jamb member 32 and the portions 210 of the head member 36 to prevent the entrance of insects or dirt into the interior of the building.

The inner stile 212 of the screen 26 is positioned adjacent the meeting rail or inner stile 54 of the fixed panel 24 and has the weatherstrip 214 to close the opening at 216. The

screen frame members

172, 196, 202 and 212 are interconnected at the corners with a mitre joint and held together by corner pieces indicated at 217 in FEGURE l. Screen cloth 21S closes the frame opening and is held in piace by the spline 22) that lits in the groove 222 extending around the inner periphery of the screen frame as best illustrated in FIGURE 5.

Spacer block 224 (FIG. 4) and spacer bracket 226 (FIG. 6) hold the screen panel 26 spaced vertically above the bracket 13) ot the operator 28. The angular shaped upwardly extending portion 228 of the bracket 226 holds the screen panel 26 in place laterally and longitudinally. The bracket 226 is secured to the sill member 33 by screws 230.

ln FIG. 3 of the drawings, the handle 132 is shown locking the ventilator 39 in a closed position. The handle 132 is slotted at 234 to receive the

links

134 and 136. Rivets 236 and 23S secure the

links

134 and 136 to the handle 132.

Rivets

240 and 242 secure the

links

134 and 136 respectively to the bracket 130. 1Rivets 24) and 242 also pass through the plate 244 that extends beneath

links

134 and 136 and cooperate with the portion 246 of the bracket 1349 to hold the links securely in place. The

links

134 and 136 are free to pivot on the rivets. Link 136 has a portion 24S that extends toward the detachable sill d. A lug 250 extends through an opening 252 in the wall 254 of the detachable sill 150, with the rounded portion 256 projecting outwardly beyond the room side of the wall 254. A rounded recess 26@ provided in the link 136 engages the portion 256 of the lug 259. The lug 259 is secured to the detachable sill 150 by screws 253.

In FlG. 5 the ventilator 30 is shown in a partially opened position with the handle 132 in the unlocked position. By engaging the bracket 130 at point 262, the handle 132 is stopped from further clockwise rotation. The ventilator 3l) is held in the partially opened position by moving the handle 132 counterclockwise until the portion 24S o the link 136 is in the position shown by the dotted lines in FIG. 5, with the rounded portions 266 and 263 engaging the wall 254 of the detachable sill 151i. The ventilator 3l? can be held by the locking handle or latch 132 in any partially opened position. The bumper 72 (FIG. 6) is positioned to stop the ventilator 30 in a fully opened position before the bracket 139 of the operator 28 strikes the meeting rail or inner stile 54 ofthe xed closure panel 24.

When the ventilator 3% is moved to the closed position, with the handle 132 in the unlocked position, the rounded portion 266 engages the portion 256. The link 136 begins to pivot about the rivet 242 and the handle 132 moves counterclockwise. Continued movement of the handle 132 draws the portion 268 against the portion 256. The handle 132 is stopped by engagement of the lug 264 with the bracket 13) thereby locking the ventilator 30 securely in place.

The center of the rivet 236 (FIG. 3) is positioned at one side of a line 274 through the center points of the rivets 238 and 24). Any movement of the ventilator 30 from the closed position will tend to move the link 136 Counterclockwise around rivet 242 by the portion 256 of the lug 250. rl`he movement of link 136 also tends to move the handle 132 counterclockwise and the center of the rivet 236 further away from the line 274. The movement is prevented by the engagement of the handle lug 264 with the bracket 130 thereby preventing opening of the ventilator 30 from the exterior of the window 2l). When unlocking the ventilator 30, the movement of the handle 132 in a clockwise direction moves the center of the rivet 236 across the line 274 thereby allowing the 6 handle 132 to swing to the opened position illustrated in FIG. 5.

The window construction of the present invention allows the fixed panel 24 to be easily installed or removed from the frame 22 and prevents removal thereof from the exterior of the building with the ventilator 30 closed and locked when in the position illustrated in FIGURES 1 and 6.

It should be understood that the jamb members, head and sill members may be secured to the structure of the building wall in any suitable well known manner and may be assembled and interconnected at their corners in a well known manner so as to provide a rectangular frame opening which is true and squared. The frame structure of the iixed closure panel is similar to the sliding closure panel.

When the window is closed the sliding panel or ventilator 3l) is in weathersealing relation to the frame 22. It is apparent that the fixed closure panel-is provided with weatherseal means around its entire periphery and likewise the sliding closure panel 36 is provided with weatherseal means at the top and bottom rails and at the inner stile and jamb member when the sliding panel is closed as best illustrated in FIGURE 6. When the ventilator 3) is open, the weatherstrip 132 prevents insects and dirt from entering the interior of the building through the space provided between the screen panel 26 and rib 162 and the vertical space provided between the screen panel 26 and the top of the detachable sill 150. The operator 28 which extends into the interior of the building from the sliding closure panel is always in sealing engagement with the weatherstrip 182 whereby insects and dirt are prevented from entering the building.
