Stuart, 5919 St, North Burnaby, British Qoiurnbia, (Ianada Filed Jan. 19, 1962, No. it; ,274 14 Claims. (U. 2-9-52) This invention relates to sliding windows with operators therefor, said windows being either the sash or sashless type.

An object of the present invention is the provision of either a single type or double type sliding window with a very simple operator therefor by means of which the win dow or windows may be quickly and easily opened and shut.

Another object is the provision of a sliding window with an operator therefor so arranged that the sliding pane may be quickly and easily removed for cleaning purposes.

Another object is to provide a sliding window which is operated by a rack and pinion, is of simple and durable construction and which may be economically manufactured.

Another object is to provide a sliding window in which no pressure is exerted on the window from the side opposite the mechanism for moving the sliding window.

Another object is to provide a sliding window in which the driving mechanism for moving the window is held in place below the bottom of the pane.

Another object is to provide a sliding window in which the glass panes of the window are not hung or fixed but are loose and removable and the sliding pane rests in a driving rack.

Another object is to provide a sliding window in which the sliding panes of the windows are driven by a rack and pinion which are not attached to the panes, and in which a locking device is provided on the driving shaft.

Another object is to provide a sliding window in which the rack for operating the sliding panes is held against the pinion by a retainer on one side and the fixed pane on the other side of the sliding pane.

These objects are accomplished by providing a rack in the form of a tray in which the sliding pane of the window rests. The rack slides with the pane in a groove in the window sill and is retained in position by the fixed pane on the outer side and a retainer on the inner side of the sliding pane. A shaft is supported by the sill and has a handle on the inner end and a pinion or pinions on its outer part. The pinion is mounted so as to engage the teeth of the rack and so move the sliding pane to the positions desired. A locking device is mounted on the Tuner part of the shaft for locking the sliding pane in the position desired. In the sash type sliding panes the rack may be mounted on the sash for contact with the pinion on the driving shaft.

Referring to FIGURES 1 to 4 of the drawings, 10 is a sashless window incorporating one form of the present invention. This window includes a frame consisting of a sill 12, jambs I3 and 14, and a header 16. The reference numeral 18 generally designates the operator for window It).

In order to accommodate the panes for window 10 and the operator therefor, sill 12 is formed in its upper surface with spaced,

parallel grooves

20 and 21 extending longitudinally from end to end thereof. A transverse groove 24 is cut through sill I substantially midway between the end thereof and extends from the front to the back of the sill. The bottom 25 of transverse groove 24 is lower than the bottoms of

grooves

20 and 21.

Window 10 is a double window and is so described herein, but it could be a single window.

Grooves

20 and 21 are identical and are made to accommodate inner and outer windows, respectively, and as these are identical, one only, namely, the inner window, will be described in detail, the same numerals being used on the identical parts of the two portions of the window. The parts of the operator for the two sections of the window are identical, and they are shown in association with a common operating shaft so that the parts for the inner window section only will be described in detail. Although the inner and outer sections of the window may be operated by a single operator shaft, it will be understood that each window section may have its own independent operator.

Each of the window sections includes a stationary pane 3% and a horizontally slidable pane 32. A side edge and the top edge of pane fit in grooves and 36 formed in jamb 13 and header 16, respectively. Similarly, a side edge and the top edge of pane 32 fit in grooves 39 and 4% in jarnb 1 and header 16. The lower edge of stationary pane 39 rests on the bottom of a groove or recess 3 formed in sill 12 at the top of groove 20 and extending along one side thereof. By referring to FIGURE 3, it will be seen that the lower edge of pane 30 partially overlaps groove 29. The lower edge of pane 32 rests on a rack which slidably extends along the bottom of groove 20.

Rack 45 has a stop 4-6 at each end thereof, these stops causing pane 32 to move with the rack. The rack has transverse teeth 43 extending along and projecting downwardly from the bottom thereof, and it is preferabie to provide

flanges

49 and 59 depending from the rack bottom along sides thereof. Rack 45 is provided with a relatively short side wall 52 which slidably extends beneath the stationary pane 36, see FIGURE 3, and with an opposed side wall 53 which is higher than wall 52 and has an outwardly projecting flange 54 along its upper end which fits into a recess or notch 56 formed in sill 12 along the upper edge of groove 2t? opposed to the groove or recess 43. A retainer 58 formed of metal, plastic or other suitable material, is removably mounted on the upper surface of sill 12 by suitable means, such as a screw 59. This retainer fits over flange 54 of rack 45 and removably retains the latter in position within the sill groove 20.

Operator 18 also includes a plate 62. fitting in transverse groove 24 and secured to sill 12 by suitable fastening means, such as screws 64 extending through holes in

lateral ears

65 and 66 which project from the plate over the upper surface of the sill between the inner and outer sections of window 10. This plate is bent to form two identical grooves 7t therein, one for each of the inner and outer sections of the window. The grooves 74 are aligned with

sill grooves

20 and 21, and each groove 7%) has a bottom 71 which is below the level of the bottom of the sill groove in which said groove 79 is located. The plate is also formed with grooves or recesses 73 and 74 at the top of groove 74? and which are positioned to align with

sill grooves

43 and 56. With this arrangement, rack 45 extends through plate groove 70 spaced above the bottom 71 thereof, stationary pane 30 extends along the plate groove 73, and movable pane 32 extends along plate groove 74.

Plate 62 is bent downwardly to form a front panel 78 which closes off the adjacent end of transverse groove 24, and if said groove extends completely from the front to the back of sill 12, plate 62 is bent downwardly at its opposite end to form a back panel 79 closing the opposite end of said transverse groove. In this example, the sup porting plate 62 has two spaced parallel grooves 70 formed therein. Aligned holes 81 are formed in the walls that constitute the sides of the two grooves 76 and in front panel .78, and a shaft 84 is journalled in said holes and projects through a casing or block 86 mounted on the outer surface of panel 78. Suitable means is provided for releasably locking shaft 84 against rotation. In this example, the shaft is provided with a plurality of annularly arranged depressions 89 in the portion thereof within block 86, and a locking bolt or set screw 90 is threaded in said block and adapted to be rotated to be moved into and out of said depressions. A suitable handle 92 is mounted on the end of shaft 84, and is secured thereto in any desired manner, such as-by means of a set screw 93.

A pinion 96 is mounted on shaft 84 in each plate groove 70 and meshes with the teeth 48 of rack 45 thereabove. The pinion fits between

flanges

49 and 50 of the rack, and a spring 98 mounted on shaft 84 between pinion 96 and the adjacent wall of plate groove 70 presses against said pinion. and normally urges rack 45 and, consequently, pane 32 inwardly with respect to window as a whole, thus separating said pane slightly from. the stationary pane ,30. 7 a a Y r As stated above, pane 32 rests upon rack 45 and is movable therewith longitudinally of sill 12. This longitudinal movement is achieved by turning handle or crank 92.to cause pinion 96 to shift the rack in accordance with the direction of rotation of shaft 84. In this example, the turning of handle 92 and the rotation of shaft 84 shifts the panes 32 of the inner and outer sections of the window simultaneously between the closed and fully open positions of window 10. If desired, two operators 18 may be provided, in which case the shaft 84 of one would have a pinion 96 for the inner section of the window, while the corresponding shaft of the other would have a pinion for the outer section of the window so that the inner and outer movable panes may be moved independently of each other. In any case, when it is desired to open or close the window, set screw 9h is turned outwardly so that it is free of shaft 84. l/Vhen it is desired to lock the movable pane or panes in a set position, screw 9%} is turned in to engage one of the depressions 89 in the shaft so that the latter cannot be rotated.

Operator 13 is a very simple mechanism for opening and closing window it). If it is desired to clean the panes 3i) and 32, it is only necessary to loosen screw 59 to permit retainer 58 to be swung from above flange 54 of rack 45. Then pane 32 may be lifted upwardly sufliciently to clear the rack, groove 49 being deep enough to permit this, so that it may be swung out of the window. It is now possible to lift pane 3d upwardly and then to swing it out of the window. If desired, rack 45 may be lifted out of place in order that the sill and plate grooves may be cleaned.

FIGURES S, 6 and 7 illustrate a horizontally movable pane 11% having a sash 111 fixedly connected to the lower edge thereof. A similar stationary pane, not shown, is provided in the window in overlapped relationship with pane 119 in accordance with standard practice. A rack 113 is fixedly secured to sash 111 and has downwardly projecting teeth 115 along its lower surface which is inclined upwardly and outwardly with respect to sash 111 as viewed in FIGURE 6. An upright member or wall 116 is secured to the window sill 117 and overlaps sash 111. A casing 12% is fixedly mounted on member 116 beneath rack 113 and has an inclined top 122. A shaft 124 is journaled in an opening 125 formed in top 122, and has a pinion 126 on its inner end within casing 120 meshing with the teeth of rack 113. A handle 123 is fixedly mounted on the outer end of said shaft.

Suitable locking means is provided for shaft 124. In this example, a locking plate 132 is threaded on threads 133 formed on said shaft, said plate bearing against the casing top 122. A fingertip 135 projects outwardly from plate 132. When this fingertip is in the position shown in full lines in FIGURE 7, locking plate 132 is in the released position. \Vhen the fingertip is moved into the position shown in broken lines in FIGURE 7, the plate draws pinion 126 against the undersurface of top 122 thereby preventing rotation of said pinion.

When locking plate 132 is released, window pane 110 is shifted along sill 117 by turning handle 128; If it is desired to remove this pane for cleaning, it is only necessary to shift the pane upwardly until rack 113 clears pinion 12.6, at which time the pane may be swung out of'the Window.

The window 143 of FIGURES l to 4 is a sashless type of window. FIGURE 8 illustrates a movable pane having a sash which may be used in a window having operator 18 of window 10. In this example, a slidable pane is mounted in a sash 142 which is U-shaped in cross section. This sash rests in the upper part of an H-shaped holder 144, and-in the lower part of this holder is located a rack 146 having teeth 147 formed therein.

Holder 144 and its rack 146 slidably fit into a groove cut in the sill of the window, said groove corresponding to groove 21) of window 111- A pinion 96 of operator 18 meshes with the teeth 147 of rack 146 so that the pane 140 may be moved by the handle of the operator.

FIGURE 9 illustrates a rack 45a having a bottom 150 with openings 151 formed therein to create teeth 152 therebetween, Rack 4511 may be substituted for rack 45 of Window, 10.

FIGURE 10 shows a rack 45b having a bottom 155 with holes 156 punched out of it. The material removed from the holes is bent downwardly to form teeth 157 to be engaged by pinion 96 when rack 45b is substituted for rack 45. FIGURE 11 illustrates a rack 45c having a bottom 160 which is pressed laterally thereof to form teeth 161.

FIGURES 12 and 13 illustrate a sashless window having an operator similar to that of FIGURES 5 to 7. In this example, a sill 170 has a groove 171 extending from end to end of the upper surface thereof. A U-shaped channel 175 is slidably mounted in this groove, and a movable pane 177 rests within this channel. A stationary pane 179 fits in an L-shaped channel 180 which also fits in sill groove 171. A rack 182 extends upwardly and inwardly from channel 175 and has teeth 183 along the bottom thereof. A pinion 185 meshes with these teeth, said pinion being fixedly mounted on a shaft 186 carried by a supporting block 187 mounted in a notch 188 cut in the upper surface of sill 179. The bottom of this notch is inclined in a plane substantially parallel to the inclined plane of rack 132. A handle 190 is fixedly mounted on the end of shaft 136 by means of which said shaft and the pinion may be rotated. Suitable locking means, not shown, similar to that of the operator of FIGURES l to 4 or of FIGURES 5 to 7, may be employed.

A U-shaped spacer strip 194 fits over the inner edge 195 of pane 177 and extends from the upper edge of channel 275 to the top of the window-frame, not shown. This strip is fixed to pane 177 and moves therewith, and forms a spacer between said pane and stationary pane 179.

Pane 177 is moved between the closed and open positions by turning handle 199. This turns pinion 135 and shifts rack 182 longitudinally in accordance with the direction of rotation. Pane 177 may be removed for cleaning merely by lifting it clear of trough 175, at which time it may be swung out of the window. Once this is done, pane 179 is lifted clear of bracket 18% and swung out of the window-frame. Channel 175 and bracket 13%) may then be removed from sill 179.
