2 Claims.

This invention relates to frames for glazing and it has particular relation to a substantially weatherproofed double panel construction.

One object of the invention is to provide an improved sealing arrangement in connection with relatively movable window sashes.

Another object of the invention is toprovide an improved window frame and multiple sash construction in which resilient sealing members maintain a substantial sealing pressure against the sash sides.

In the drawings:

Fig. 1 is a side elevation of a window construction in which the invention has been incorporated; Fig. 2 is a fragmentary vertical section, on a larger scale, taken substantially along the line lI- -II of Fig. 1; Fig. 3 is a fragmentary horizontal section, on a larger scale, taken substan tially along the line III-Il1 of Fig. 1; Fig. 4 is a fragmentary elevation illustrating a comer portion of a glazed sash; Fig. 5 is afragmentary end elevation of the structure shown in Fig. 4; Fig. 6 is a fragmentary horizontal section taken substantially along the line VIVI of Fig. 4; Fig. 7 is a fragmentary cross section, on a larger scale, taken substantialy along the line VII-VII of Fig. 1; Fig. 8 is across section similar to Fig. '7 of another form of sash structure; Fig. 9 is a vertical section similar to Fig. 2 illustrating another form of sealing structure; and Fig. 10 is a cross section similar to Fig. 2 including double glazed units.

In practicing the invention, sashes are slidably mounted in a frame structure 21 which is carried in a wall 23 of a building, or the like. A resilient sealing member 25, which can be composed of rubber or metal, is provided with a base 26, and with inwardly converging resilient flanges 2'! which are clamped between the frame structure 2| and the wall by means of suitable fasteners 28. The flanges 21 are curved inwardly toward each other and are so constructed that their outer edges tend to bear against each other and resiliently resist separation. The sashes 20 are adapted to receive single glazed units 29 (Fig. 2) or double glazed units 29 (Fig. 10).

The frame structure 2| which is T-shaped in cross section includes an inwardly projecting flange 30 and serves as a rail for slidably supporting the sashes 20. Peripherally flanged rollers 38 are mounted'upon pins 33 that are carried transversely and intermittently in the flange 30 and such rollers constitute supporting guides for the sashes 20 on opposite sides of the flange 30. Guide flanges or runners 35 are formed along the edges of the sashes and ride in guided relation upon the flanged rollers 3|.

The inner marginal portion of the flange 30 is formed with an integral transverse section 36 which has guiding ribs 3! along opposite edges thereof running approximately half the distance of the length of the sash-containing frame structure. Grooves 38 formed in the sashes adjacent the guide flange receive these ribs which assist in maintaining the sashesin properly guided relation in the frame structure.

In assembling the elements described, th resilient flanges 21 are spread to receive the marginal portions of the sashes 20 which are inserted in the frame adjacent the ribs 31 and fitted thereon. The rollers 3| are mounted after the sashes have been installed. It is to be understood that the upper portion of the frame is also constructed in the manner described in order to be adapted to receive rollers corresponding to the rollers 3!.

When the sashes 20 are in closed position with their adjacent edges slightly overlapped (Fig. 7), proper sealing relation is maintained at the joint between such sashes by means of rubber channel members 39 having ribbed portions 40 and overlapping lips fll which assist in perfecting the seal. As best shown in Figs. 4, 5 and 6, the inner opposed comer portions of each sash are provided with inclined surfaces 45 and a cut out portion 48 which are designed for the purpose of facilitating the sealing action of the resilient flanges 21. By this arrangement, the gap between the inner extremities of the sashes and the flange 30 is substantially closed without abruptly distorting or bending the resilient flanges 21. In the form of sash shown in Fig. 8, the resilient channels are composed of metal instead of rubber.

Referring to Fig. 9, it is to be noted that he sealing flanges 21 can be in the form of resilient metal channels having lower flanges 48 which are adapted to be snapped behind shouldered elements 49 that are rigidly formed upon opposite sides of the supporting flange 30. These metal flanges 21 operate in substantially the same manner as the rubber flanges of the other construction described although they are not so flexible. closed position abut the flanges 21 as shown in Fig. 3, and these flanges are adapted to yield and maintain sealing pressure upon the ends of the sashes. If desired, a stiffening strip 50 can be inserted in the sealing member 25 along the vertical portions thereof.

Although practical construction involving the The vertical sides of the sashes in their.

in guided relation upon the flanged rollers, the outer opposite faces of the sashes having shoul-' dered portions, and a sealing channel having converging resilient walls yieldably engaging the shouldered portions of the sashes, said walls along their longitudinal edges bri ging th space from the edge oi the sash to the rail and thereby providing a substantially continuous seal from sash to rail at the marginal portions of the sash.

2. In a window construction, a plurality bi glazed sashes relatively movable in adjacent parallel planes, a guide rail interconnected with the sashes in sliding relation, flanged rollers carried by the guide rail, runner flanges formed on the sashes and riding in guided relation upon said rollers, the outer opposite faces of the sashes having shoulder portions, and a flexible channel in fixed relation with th rail and having resilient walls yieldably engaging the shoulder portions, said runner flanges terminating in inclined suri'aces and conforming the flexible edges oi the walls to engage in inclined sealing relation from the sashes to the rail.
