SLIDING CLOSURE AND SUSPENSION SYSTEM THEREFOR Filed Jan. 16, 1950 3 Sheets-Sheet 3 /N VENTOR.

BY HIS ATTORNEYS.

A BRHHHM GROSS/WAN em M Patented Feb. 3, 1953 UNITED STATES PATENT OFFICE SLIDING CLOSURE AND SUSPENSION SYSTEM THEREFOR 11 Claims. 1

This invention relates to improvements in sliding closures and, more particularly, to sliding closures adapted for use as doors and windows in various types of structures.

To facilitate the disclosure of the construction and mode of operation of a closure constructed in accordance with my invention, the invention is exemplified as embodied in a door having a fixed sash and a movable sash but, of course, any number of movable and fixed sashes can be utilized in combination and it is obvious that the principles of the invention are equally applicable to both door and window construction.

A common deficiency of conventional sliding closures is the fact that such closures are so constructed that the entry of air and moisture into the structures with which they are associated is possible due to the difliculty of completely weather-stripping such movable sash structures by accepted methods.

It is, therefore, a primary object of my invention to provide a sliding sash closure which is characterized by great resistance to the ingress of air and moisture into the structure with which it is associated.

An additional object of my invention is the provision of a sliding closure in which the movable sash of the sliding closure is provided with resilient sealing means for preventing the ingress of air and moisture into the structure with which i the sliding closure is associated. An associated object of my invention is the provision of a sliding closure for structures in which the movable sash component has the resilient sealing means positioned, in recesses formed in the sliding closure, said resilient sealing means being carried in the recesses and moved concomitantly Wtih the movement of the movable sash of the sliding closure.

Another object of my invention is the provision of a sliding closure, the movable sash of which is provided with a plurality of recesses to receive the aforementioned sealing means. These recesses protect the sealing means from injury and also permit the sealing means to be installed without the use of fasteners.

A further object of my invention is the provision of resilient sealing means for the movable sash of a sliding closure which is adapted, in addition to scaling the closure against air and moisture, to orient the movable sash of the closure in reference to the track means upon which the movable sash is supported and upon which it moves.

A further object of my invention is the provision of resilient sealing means for the movable sash of the sliding closure which serves to absorb shock loads imposed upon the movable sash by sudden gusts of wind and accidental blows to prevent the shattering of the glass supported in the movable sash.

Another object of my invention is the provision in the frame of the sliding closure of positioning means adapted to supplement the action of the resilient sealing means in orienting the movable sash with reference to the frame and also to supplement the action of the sealing means in its weather-stripping and shock absorbing functions. An associated object of my invention is the provision of positioning means of the aforementioned type which is resilient in nature and which contacts the entire length of the movable sash at the top, bottom and side thereof.

Another common defect of conventional sliding closures is the fact that it is frequently very difiicult to wash the glass mounted in the sliding closure, particularly if the movable sash of the sliding closure is, in the case of a window, accessible from the interior of the structure only or, in the case of a door, where the movable sash is relatively high and accessible only by specialized cleaning instruments.

A further object of my invention is the provision of a sliding closure for structures in which the movable sash is so mounted in the frame of the closure that it may be readily lifted from its engagement with the frame to facilitate the cleaning thereof. The construction of the movable sash permits its easy removal from engagement with the frame of the closure and permits access to the resilient sealing means of the movable sash and to the component parts of the frame of the closure to permit the adjustment, servicing or replacement thereof.

After conventional closures have been installed in a structure, sagging of the head of the opening in which the closure is istalled frequently occurs, placing bending loads upon the upper portion of the frame of the closure which cause the downward deflection of the upper portion of the frame and prevent the free movement of the movable sash of the closure within the frame. In such cases, it is frequently necessary to remove the closure from the opening and to reinforce the structure around the opening before the closure can be replaced.

A further object of my invention is the provision of a slidable closure for the openings in a structure in which the frame thereof, and particularly the upper portion of the frame, is adjustable to permit the downward sagging of the structure surrounding the frame to be compensated for to prevent the binding of the movable sash of the closure in the frame. This adjustment of the frame may be readily accomplished by removing the movable sash from the frame in the above-described manner.

An additional object of my invention is the provision of a sliding closure for structures, the frame of which can be mounted in an Opening in the structure with a minimum of fastening means, thus greatly facilitating the installation of the closure.

An additional object of my invention is the provision of a sliding closure for structures which is composed of a relatively small number of interchangeable parts which can be used to serve similar functions in different portions of the closure structure. This materially reduces the cost of fabricating the closure and facilitates the shipping and the installation of the closure.

Other objects and advantages of my invention will be apparent from the following specification and the accompanying drawings, which are for the purpose of illustration only, and in which:

Fig. 1 is a perspective view showing the installation in a structure of a door constructed in accordance with my invention;

Fig. 2 is a vertical sectional view taken on the broken line 2-2 of Fig. 1;

Fig. 3 is a longitudinal sectional view taken on the broken line 3--3 of Fig. 2;

Fig. 4 is a fragmentary, partly sectional view taken on the broken line 4-4 of Fig. 2;

Fig. 5 is a fragmentary, partly sectional view taken on the broken line 5-5 of Fig. 2; and

Fig. 6 is a detail of a component part of the frame structure of the closure.

Referring to the drawings and particularly to Fig. 1 thereof, I show a closure In for an opening H in a structure l2, the closure l0 being exemplified as a door |3 having a fixed sash M and a movable sash l5. Although my invention is described as being embodied in a door l3 having a fixed sash I4 and a movable sash I5, I do not intend that my invention be limited to the combination of a fixed sash with a movable sash since it is obvious that the use of a fixed sash can be dispensed with and any number of movable sashes be used in combination. It is also possible to use one movable sash or more than one movable sash in conjunction with a plurality of fixed sashes.

The opening II in the structure I2 is defined at the top thereof, Fig. 2, by a head H to which is attached by suitable fasteners, not shown, a lintel IS, the base of the opening being defined by a sill l9, said lintel and said sill being preferably formed of wood or similar material. The sides of the opening in the structure l2, Fig. 3, are defined by jambs 28. The lintel l8, the sill l9 and the jambs 2|] together define a substantially rectangular opening to which is secured and in which is positioned a frame 22 of the sliding closure which is the subject of my invention.

The frame 22 includes a top member 23 and a bottom member 24, Fig. 2, which are connected to each other by side members 25 and 25, Fig. 3. The top member 23 is constituted by an elongated channel member 29, preferably extruded from aluminum, and having formed integrally therewith at the inner edge thereof a downwardly depending top track 30. The channel member 29 defines a channel 3| in which is adapted to be positioned a plurality of suspension clips 32 which are spaced along the channel 3| at predetermined intervals and which are formed of stainless steel or similar material. A plurality of openings 33 is formed in the channel member 29 adjacent the top track 33, said openings being adapted to register with oppositely positioned openings 34 and 35 formed in the suspension clip 32. Suspension bolts 36 are inserted through the openings 33, 34 and 35 and screwed into the lintel Hi to support the channel member 29 at the top of the frame 22.

The use of the suspension clips 32 in conjunction with the channel member 29 permits the top frame member 23 to be rigidly fastened to the under side of the lintel H3 at the inside edge of the channel member 29 alone, the clip 32 serving to distribute the load through the channel member 29. As will be noted, the top frame member 23 is thus fastened to the lintel |8 by a minimum number of bolts which are juxtaposed to the top track 30 and which are readily accessible from the interior of the structure in a manner which will be described in greater detail below.

It will be noted that a gap 37 is permitted to exist between the top of the channel member 29 and the bottom of the lintel Hi. It has been discovered that, particularly where the openings in the structure are of relatively great length, the lintel I8 bends as the structure settles, causing it to sag and to impose a load upon the top frame member, thus preventing the proper functioning of the movable sash l5 of the closure ID. When such sagging of the llintel |8 due to the settling of the structure |2 occurs in a structure equipped with the closure I0 of my invention, the sagging of the lintel I8 is accommodated by taking up the suspension bolts 36 by screwing them into the lintel I8 a sufiicient distance to accommodate the downward deflection of the lintel. Because of the accessibility of the comparatively few suspension bolts utilized in suspending the channelmember 29, this adjustment can be accomplished with relative ease and the necessity for completely removing the closure from the opening or for reworking the frame of the closure is eliminated. This is a very important feature of my invention.

The bottom frame member 24 is constituted by an elongated channel member 39 having a downwardly sloping upper surface 40 to facilitate the run-off of moisture and having legs 4| and 42 adapted to support it upon the sill Hi. The inner leg 4| is provided with a right angle flange 43 in which is formed a plurality of openings 44 adapted to receive screws 45 which secure the channel member 39 to the sill IS. A mastic sealing compound 46 may be utilized to seal the top and bottom channel members 29 and 39 to the structure l2 against the ingress of air and moisture. Formed integrally upon the inner edge of the bottom channel member 39 and projecting upwardly therefrom, is a bottom track 50 which, in conjunction with the top track 30, supports the movable sash l5 of the door |3 in a manner which will be described in greater detail below.

The side frame members 25 and 26 are constituted by channel members 5| and 52, the configuration of which is identical with that of the top channel member 29, the channel members 5| and 52 being attached to the jambs 20 of the opening H by means of clips 53 and fasteners 54 passing through said channel members 5| and 52 and clips 53. Shims 55 interposed between the channel members 5| and 52 and the jambs 20 serve to adjust the side members 25 and 26 in reference to the opening II in the structure l2. Each of the channel members and 52 has laterally projecting engagement means 56 formed integrally therewith, for a purpose which will be described in greater detail below. Juxtaposed to the engagement means 56 are resilient bumpers 51 which are secured in openings in the channel members 5| and 52. The channel members 29, 39, 5| and 52 may be fastened to each other by any conventional means, such as welding. The use of identical channel members 29, 5| and 52 to form the top and side members 23, 25 and 26 materially reduces the cost of fabricating the frame 22 of the closure H).

The fixed sash I4 includes top and bottom rails 59 and 59 connected to each other by stiles 60 and BI, the top and bottom rails 58 and 59 and the stiles 59 and 5| being formed from lengths of extrusion 63 having identical configurations. Since the extrusions forming the fixed sash M are identical in configuration, a description of the extrusion which constitutes the stile 60, Fig. 3, will sufiice as a description of the extrusion constituting the top and bottom rails 58 and 59 and the other stile 9 I.

The length of extrusion 63 which forms the stile 69 includes a closed channel 64 having juxtaposed thereto a channel 65 provided with a longitudinal opening or slot 95. Formed integrally with the body of the extrusion 53 is a later-ally projecting flange 51 which is spaced from a wedge-shaped key 68 formed integrally with the extrusion 63 and oppositely disposed to the flange 9'5. The stile 69 of the fixed sash I4 is secured to a rib 69 projecting from and formed integrally with the side frame member 25. The opposite stile 9! is fastened to an angle 19 which extends between the bottom frame member 24 and the top frame member 23. The top rail 58 of the fixed sash I4 is secured to a downwardly projecting rib 1| formed integrally with the top frame member 23 and the bottom rail 59 is mounted upon an elongated supporting channel 12 which rests upon the sloping upper surface 40 of the bottom frame member 24 and which is coextensive with the bottom rail 59. The primary function of the channel 72, in addition to supporting the fixed sash, is to prevent ingress of water into the structure by presenting a barrier to the passage thereof under and between the moving and fixed sashes. The upper surface of the longitudinal supporting channel 12 is provided with upwardly projecting detent means 13 which are received in the opening 66 provided in the channel 55 of the extrusion 93 and the open end of the channel 12 is closed by means of the angle which extends between the bottom frame member 24 and the top frame member 23.

A sheet of glass 14 is mounted in the frame of the fixed sash M by means of glass retaining means 15 having keys 16 mating with the keys 68 on the extrusions 63 and pressure arms I1 adapted to force the edges of the sheet of glass 14 against mounting strips 18 preferably formed of mastic impregnated sponge rubber.

The movable sash includes top and bottom rails 99 and 9| and stiles 82 and 83, the top and bottom rails 89 and 8| and the stiles B2 and 83 being formed of lengths of extrusion 63 identical in all respects with the lengths of extrusion 63 constituting the frame of the fixed sash l4. However, the extrusion 63 utilized in the bottom rail, 9| of the movable sash I5 is modified to a certain extent for a purpose which will be described in greater detail below.

The top rail 89 of the movable sash l5, Fig. 2, is constituted by a length of extrusion 63, the channel 65 therein providing a recess which extends the length of the top rail 89 and which is adapted to receive and has positioned therein an elongated, resilient sealing member 86 formed of spring sheet stock and having a central, substantially U-shaped portion 81 and downwardly directed centering arms 89. The U-shaped portion 8? of the resilient sealing member 85 provides a longitudinal groove or recess 89 which is adapted to receive the lower end of the top track 99. The top rail 89 of the movable sash I5 is thus slidably mounted upon the track 3|! through the intermediary oi the resilient sealing member 85 and a seal is created between the lowermost end of the track means 39 and the U- shaped portion 8'! of the resilient sealing member to prevent the ingress of air and moisture past the top rail 89 of the movable sash l5. It will be noted that the lowermost end of the top track 39 is maintained in the center of the top rail 99 by its position in the groove 99 provided by the U-shaped portion 9'! of the resilient sealing member 89, the resilient sealing member thus serving to properly orient the top rail 99 of the movable sash l5 in respect to the track means 39. In addition, when a shock or undue load is placed upon the movable sash, as by means of a gust of wind or an accidental contact with the movable sash l5, the centering arms 99 are able to deflect sufiiciently to absorb the shock and to permit the momentary deflection of the movable sash i5 to prevent injury to the sash. Of interest also is the fact that the contact of the top track 39 with the resilient sealing member is substantially a point-to-point contact and frictional drag induced by the sliding contact of the resilient sealing member 39 with the track 99 is maintained at a minimum, thus permitting the easy movement of the movable sash l5. The sealing means 89 is coextensive with the top rail 89.

Secured to the under side of the channel 29 constituting the top frame 23 by means of an elongated extrusion 99, which is disposed upon the under side of the top frame member 29, and secured to the downwardly projecting rim H thereof between the angle i9 and the side frame member 29, is a positioning means 9| exemplified as an elongated spring 92 having a resilient arm 93 impingingupon the outer edge of the top rail 89 of the movable sash l5 and making a point-topoint contact therewith. The positioning means 9| serves to supplement the orienting action of the resilient sealing member 8-5 and also serves as an auxiliary means of preventing the entry of air and moisture into the structuer past the top rail 89 of the movable sash l5. Of course, when the movable sash is subjected to undue and sudden loads, the deflection of the movable sash as permitted by the resilient sealing member 86 causes the simultaneous deflection of the resilient arm 99 of the positioning means 9|.

The bottom rail 9| of the movable sash I5 is formed from a length of extrusion 53, the channel 65 constituting a recess 94 into which the bottom track member 59 projects upwardly through the opening 69. The dividing wall between the channel 94 and the channel 95 has been removed and positioned upon spindles 95 pressed into the side walls of the extrusion 53 are rollers 99 which engage the upper end of the bottom track 59. The rollers 99, as best seen in Fig. 5,

project upwardly into the channel 64 through openings 91 formed in the elongated, resilient sealing means 88 which is positioned in the recess 94 and which engages the sides of the roller 96 to prevent the ingress of air and moisture into the interior of the structure. In addition, it will also be noted, Fig. 2, that the resilient sealing member 83 also contacts the sides of the bottom track 56 and the area of the extrusion 63 adjacent to the opening 66 therein, to insure that no air or moisture will enter the structure past the bottom rail BI of the movable sash I5.

When it is desired to remove the movable sash it from contact with the top track 30 and the bottom track so to facilitate the cleaning thereof, the adjustment of the top frame member 23 to compensate for the downward deflection of the lintel I8 or to permit the servicing and/or repair of any of the portions of the closure, the movable sash is lifted vertically to cause movement of the top track 30 into the groove 89 and to lift the rollers 93 out of contact with the track 59 and to disengage the track 50 from the resilient sealing member 85 and the opening 68 in the extrusion 53. When this has been accomplished, the movable sash I can be lowered to disengage the top track 39 from the groove 89 in the resilient sealing member 86. The movable sash i5 is thus, in two movements, completely freed from engagement with the top and bottom tracks 30 and 59 respectively and may be suitably positioned to facilitate the cleaning of the sash. As is obvious, when the sash is removed from the tracks 30 and 59, the suspension bolts are readily accessible for permitting the adjustment of the top member 23 of the frame 22 to compensate for the vertical deflection of the lintel I8. In addition, should it be necessary to repair or service the resilient sealing members 85 embodied in the top and bottom rails 89 and 8I it is only necessary to press the U-shaped intermediate portions 81 thereof together to pass the resilient sealing members 853 through the openings 56 into the top and bottom rails 83 and BI in order to completely disengage the resilient sealing members from the top and bottom rails.

lhe stiles 82 and 83 of the movable sash I5, Fig. 3, are formed from lengths of extrusion 63 and th longitudinal channels 55 of the stiles are adapted to engage the engagement means 56 formed upon the side members 25 and 26 of the frame 22. Positioned in the recess 65 of the stile 83 is an elongated sealing member 36 which is identical in all respects with the previously discussed sealing members 86 of the top and bottcm rails 89 and 8E and which includes the U-shaped central portion 81 and the centering arms 88, the U-shaped central portion 31 defining a longitudinal groove 89 adapted to receive the engagement means 56 of the side member 28 of the frame 22 when the movable sash I5 is closed thereupon, as best shown in Fig. 3 of the drawings.

When the movable is in either the extreme open or extreme closed position, the bumpers 57 mounted upon the side members 25 and 26 of the frame 22 are contacted by the stiles 32 and 83 respectively and also serve to prevent damage of the movable sash I5 when the movable sash is closed or opened with undue force. Mounted upon the side frame member 26 and adapted to engage the outer surface of the stile 83 when the movable sash I5 is moved into closed position and into engagement with the engagement means 56,

is an auxiliary sealing means 99 constituted by an elongated, vertically positioned resilient weather stripping IOI which is secured to the side frame member 26 by means of an extrusion H22 which is, in turn, fastened to the vertical frame member 26. The auxiliary sealing means 99 supplements the action of the resilient sealing means 85 mounted in the recess 65 of the stile 83 and prevents ingress of air and moisture into the structure with which the closure is associated.

Secured to the stil 82 of the movable sash is an engagement means I06 constituted by a vertically positioned extrusion 205 having a leg I06 adapted to engage with engagement means I01 constituting a portion of the angle I0. Thus, as best shown in Fig. 3, when the movable sash I5 is in the closed position the leg I06 of the engagement means I04 engages the engagement means lfi'i to form a seal therebetween to prevent the ingress of air and moisture between the stile 82 of the movable sash i5 and the stile 6! of the fixed sash i4. Secured to the stile SI of the fixed sash I4 is a positioning means I69 for the engagement means Hi4 and it! which is adapted to impinge upon the end of the leg IE6 of the engagement means I64 and which is adapted to force the engagement means I04 into closer contact with the engagement means I07. The positioning means 659 is constituted by an elongated spring 5 is secured to and disposed between the angle I0 and the stile 6!. In this manner, the entry of moisture and air between the stile SI of the fixed sash. and 82 of the movable sash is obviated.

Positioned in the frame of the movable sash I 5, as constituted by the top and bottom rails and Si and the stiles 82 and 83, is a sheet of glass II2 which is retained therein by means of glass retaining means 75, the sheet of glass II2 being positioned between the glass retaining means 15 and strips f 8 of mastic impregnated sponge rubber sealing material.

As may be observed from Figs. 2 and 4 of the drawings, when the movable sash I5 is in closed position a gap II3 exists between the under side of the movable sash I5 and the edge of the supporting channel '52 which would permit the entry of air and moisture into the interior of the structure if some means were not provided for automatically closing off the gap I Hi. To prevent the ingress of air and moisture through the gap II3, there is mounted upon a base II4 by means of a screw IE5 a weather block II 6 consisting of a resilient spring II? which impinges on the under side of the movable sash I5 and thus closes off the gap IE3 to prevent the ingress of air and moisture therethrough, as best seen in Figs. 2, 3 and 4. I thus provide by my invention a sliding closure for structures which is characterized by extreme simplicity of construction and by the utilization or relatively few, interchangeable parts. A window or door constructed in accordance with my invention, when installed in a structure, will prevent the ingress of air and moisture into the structure since sealing means to prevent such ingress have been provided at all points of the closure where such entry of air and moisture might take place. H An additional feature of my invention is the Iact the sealing means embodied therein serve also to orient the movable sash of the closure with respect to the frame thereof and to absorb shock loads imposed thereupon to prevent breakage of the glass supported in the movable sash. Also of note is the fact that the movable sash o1 the closure can be very easily translated because the sash is supported upon the frame of the closure by point-to-point contact and frictional losses occasioned by frictional drag are reduced to a minimum.

Also of importance is the fact that the movable sash of the sliding closure can be readily removed from the frame of the closure in which it is mounted to facilitate the washing of the-sheet of glass supported in the movable sash or to permit the servicing or adjustment of the component parts of the movable sash or the closure frame. The adjustability of the frame of the closure to compensate for sagging in the structure with which the closure is associated is also an important feature since it insures that the movable sash of the closure will not be subjected to bending loads which would cause it to bind and prevent free movement thereof. Generally speaking, a door or window when constructed in accordance with my invention is characterized by extreme resistance to the entry of air and moisture therepast, by ease of maintenance and repair, by extremely easy movement of the movable sash of the door or window, by eliminating any contact of the sash with rigid metal in operating or closed positions, and by facility of installation and construction.

Although I have shown and described a preferred embodiment of my invention for the purpose of illustrating the construction and mode of operation thereof, it is obvious that changes, modifications and alterations may be made in the specific details of said construction and I, therefore, do not desire to be limited to said specific details but prefer, rather, to be afforded the full scope of the following claims.
