REVERSIBLE SLIDING DOOR AND WINDOW CONSTRUCTION Filed Feb. 3, 1965 Tram/5K6 United States Patent 3,370,383 REVERSBLE SLE-SING DR AND WINDW CONSTRUCTGN Harry lli. liegelrnan, Railing Hills, Calif., assigner to Ader Corporation, Fullerton, Calif., a corporation of Caliornia Filed Feb. 3, i965, Ser. No. 436,126 12 Claims. (Cl. t9-425) This invention re.ates generally to sliding closure members, and more particularly to improvements in reversible sliding sash construction r windows, doors and the like.

Sliding door and window construction commonly includes an aluminum-framed glass door or window which slides open from a lock jamb in a direction towards a normally fixed glass panel, usually closely adjacent and parallel thereto. Both the sliding sash and the fined panel are normally mounted in a casing conventionally set in an openinU in the wall of the building. Rollers are normally mounted in the lower rail member of the sli-ding sash, and the casing is usually provided `with cooperating means, such as a parallel upstanding lin in the sill member of the casing, which acts as a runner for the bottom rollers of the sash.

Sliding sashes can be installed to open from left to right, or right to lett, according to the necessity imposed by surrounding structures, or as desired. Moreover, the sliding sash must be set squarely (through adiustable rollers) for proper operation within the casing. if the casing is intentionally constructed out of square in following an inclined course and resembles a parallelogram, the sash must of course be made to conform. Otherwise, the out of square condition encountered gives rise to several problems. First, when the stile of the closure member meets the jamb of the metal frame, the stile will not seat itself parallel to the jamb, and drafts and cold air may readily enter through the gap between the jamb and the stile. Secondly, typical locking mechanisms aixed to the stile usually have a projection adapted to engage a locking groove in the door or window frame or in the mullion of a stationary panel. However, if the metal frame is out of square, the locking projection will not be readily accepted by the locking groove, thus making locking of the slidable closure member diliicult, if not practically impossible.

Hence, it is clearly desirable that a sliding sash have individually adjustable rollers in order to obtain the close adjustment necessary to meet an out of square condition. Such sashes are particularly useful when they can be readily reversed with little or no structural modifications,

While adjustable rollers for slidable closure -members are, per se, well known in the building industry, such rollers have not heretofore proven entirely satisfactory from the standpoints of economy, reliability, range and ease of adjustment, and smoothness of roller action.

Accordingly, it is an object or" the present invention to provide a new and improved sliding sash construction which overcomes the above and other disadvantages of the prior art.

Another object is to provide a reversible sliding sash for doors, windows or the like, which can be readily installed in the casing to open from either left to right or right to left.

' A further object of this invention is the provision of a reversible sliding sash having adjustable rollers which can be easily adjusted to square the sash within the casing in which it slides.

Still another object iS to provide a new and improved roller means for a sliding sash which permits highly eective, nonbinding movement of the sash along the casing in which it is mounted.

Yet another object of this invention is the provision of 31,3 ,383? garenne rei. 2r, lass .dal

a relatively simple, economical, and reliable roller means for a sliding sash which permits easy adjust-ment over a wide vertical range to compensate the sash for the out of square condition ot the frame in which it is adapted to slide.

The above and other objects and advantages of this invention will become apparent from the following description, when taken in conjunction with the accompanying drawing of an illustrative embodiment thereof, and wherein:

FIGURE l is a side elevational view of a sliding sash window construction in accordance with the present invention, as observed from the inside of a building in which the window is mounted;

FIGURE 2 is an enlarged, partial sectional view, taken along the line 2 2 in FIGURE 1, and illustrates the adjustable roller means at the lower right corner of the sliding sash;

FIGURE 3 is a partial, sectional view of the sliding sash and sill, taken along the line 3 3 in FIGURE 2;

FGURE 4 is an enlarged, partial sectional view of the roller means, taken along the line 4 4 in FIGURE 3;

FIGURE 5 is a perspective view of a new and improved roller means in accordance with the present invention; and

FIGURE 6 is a sectional view through the roller means, taken along the line `6 6 in FIGURE 5.

Referring now to the drawings, and particularly to FGURE l thereof, the construction embodying the invention is shown as a window by way of illustration only, and is not to be construed as limiting the invention. The window construction includes an outer window frame or casing l@ which is set in an appropriate opening in the wall i2 of a building. The casing 10 is preferably fabricated from extruded aluminum head, sill and jamb frame members i3, 14, 15, respectively, which are suitably formed to provide cooperating ilanges, ridges and channels that engage and accommodate a movable left hand window sash or panel 16 and a normally fixed window panel 17. The jambs 15 of the casing 10 may be aixed to the head i3 and sill i4 in any suitable manner, as by corner screws or the like (not shown).

The sliding sash lo is also preferably fabricated from extruded aluminum frame members including left and right stile members 18, 2li, respectively, and upper and lower rail members 22, Zal, respectively. The stiles 18, 2li are secured to the

rails

22, 24 in any appropriate manner, as by the corner Screw 26 shown in FIGURE 2.

Referring now more particularly to FEGURES 2 5, the frame of the sliding sash lo has two individually adjustable roller means 3i) aixed to the stile at each lower corner thereof. Each of these roller means 3Q is vertically adjustable along the stile in which it is mounted, to control the height of the sash corner at which the partrcular roller means is located. In this manner, the Sash le can be aligned within the casing lo regardless of the out of square condition ofthe casing.

As best observed in FIGURES 4 6, the roller means 3d comprises a mol-ded, one-piece plastic roller body 32, preferably fabricated from nylon or the like. The roller body 3?. has a generally elongated rectangular crosssection and is formed with an elongated channel 34 of a prescribed width. The channel 34 extends from the base of the roller body 32 approximately half way up the roller body, and thus divides the lower part 0f the roller body into a pair of parallel,

resilient walls

36, 38.

The inside face of each of the walls 35, 3S dened oy the channel 34 is provided with integral half axles 4d, 42, respectively, which normally abut each other to dene a single axle for mounting a wheel 44 and to prevent inward flexing ofthe walls 36, 33.

The wheel 44 is also preferably made 0f nylon or other tough plastic material, and the wheel is provided with a central aperture adapted to receive the half axles 49, 42 when the wheel is installed within the roller body 3i). The thickness of the wheel 44 is slightly less than the normal spacing between inside faces of the

walls

36, 38.

Y In order to mount the wheel 44 upon the half axles 4l), 42, the normally

parallel walls

36, 38 are spread apart to permit'insertion of the wheel 44 between the walls in a'manner enabling the half axles to enter the central aperture of the wheel. Once this has been done, the

walls

36, 38 are permitted to return to their normal parallel state. This brings the leading ends of the half axles 4G, 42, into abutment with each other to prevent further inward movement of the

walls

36, 38. Hence, the wheel 44 rotates freely within the channel 34 of the roller body 30 with` no tendency whatsoever to bind against either of the

roller body walls

36, 38.

As best observed in FIGURES 2 and 4, the stile 2t) includes a pocket 46 defined between an inner stile cross member 4S and a pair of outer guide flanges S0, 52 which run the entire length of the stile extrusion. A portion of the roller body 32 is housed within the pocket 46 and moves along the stile guide flanges St), 52. When the roller body 32 is in the desired position, a nut 54 (preferably of metal) is drawn tightly against the inside faces of the guide fianges S0, 52 by means of an adjusting screw 56 whichV passes through the roller body 32 and into threaded engagement with the nut S4.

In order to enable the roller body 32 to move along the stile 2) in the space between the

guide iianges

50, 52, opposite sides of the roller body are provided with longitudinal guide grooves S8, 60 extending the full height of the roller body and adapted to mate in sliding engagement with the corresponding

stile guide flanges

50, 52, respectively.

In addition, a pocket 62, extending between and intersecting the grooves 58, 6i), is formed in the roller body 32 at the upper end thereof to house the nut 54 within the roller body.

The cooperation between the

stile flanges

50, 52 and the roller body guide grooves 58, 60 enables smooth, easy movement of the roller means 30 vertically along the stile. When the desired position of tbe roller means 30 along any particular stile has been reached, the screw 56 is rotated to wedge the stile flanges 50, S2 between one face of the nut 54 and the opposite roller body walls defining the guide grooves 58, 60. The clamping action obtained thereby is highly etcient and reliable. The metal nut 54 bites into the metal of the

stile fianges

50, 52 and is not prone to looseness induced by vibration encountered during use of the window.

In order to limit the vertical travel of the roller means 30 along the stile, the lower end of the roller body 32 Y is provided with a pair of horizontally outwardly extending, integral limit tabs 64, 66 projecting from the outer faces ofthe

walls

36, 38, respectively.

Since the roller means 30 are completely interchangeable and may be mounted in any corner of the sash frame, the sash 16 is readily reversible for either left to right or right to left sliding movement within the casing 10. All that is necessary in order to reverse the sash 16 is to remove the sash, rotate the sash 180 about an axis perpendicular to the plane of the sash, remove the roller means 30 from the two corners of the sash. which were previously at the bottom (now on top), and re-install the roller means 30 in each of the new Vbottom corners of the sash.

It will be apparent from the foregoing that, while a particular form of my invention has been illustrated and described, various modifications can be made without departing from the spirit and scope of my invention. Accordingly, I do not intend that my invention be limited, except as by the appended claims.
