SLIDING SA SH ASSEMBLY WITH STORM WINDOW INVENTOR ROBERT F. OBER Filed Oct. 30. 1967 ATTORNEYS United States Patent 3,427,747 SLIDING SASH ASSEMBLY WITH STORM WINDOW Robert F. Ober, Sr., 2916 Flad, St. Louis, Mo. 63110 Filed Oct. 30, 1967, Ser. No. 679,125 US. Cl. 49-162 4 Claims Int. Cl. Ed 7/06 ABSTRACT OF THE DISCLOSURE A sliding sash assembly of standard construction equipped with a pair of hingedly mounted window panes in which one of the panes provides the normal glazing and the other forms a storm window, the window panes opening relatively inwardly for purposes of access for cleaning and repair.

This invention relates to improvements in sliding sash assemblies, and is particularly concerned with providing inner and outer panes in the standard sliding sash.

A particularly annoying and persistent problem with sliding sash assemblies is the inaccessibility to the panes of glass for the purpose of cleaning the exterior surfaces. In the sliding sash, when one sash member is raised or lowered, it overlaps the companion sash and thereby creates the problem of inaccessibility. This is a great nuisance to the home owner because of the inability to adequately clean the outer surface. In addition to the foregoing problem there is the greater nuisance problem of installation of storm sash or other cold weather protecting means. Usually storm protection is obtained by a completely independent and separately installed storm sash which is applied and removed entirely from the exterior of a building. It is quickl obvious that independent storm sash increases the problem of accessibility to the window pan surface.

The presently improved sliding sash assembly with storm windows overcomes the nuisance problem as above briefly outlined in a very simple and novel manner. In a preferred arrangement each sliding sash is provided with a pair of hingedly mounted frame members, and each frame member supports the usual window pane which may be glass or other suitable transparent material. The hinged frame members are arranged in pairs in each sash so that there is an interior pane and an exterior pane for storm protection. The preferred arrangement is such that the fame members swing inwardly for accessibility when cleaning is necessary, and yet when in the closed position there is secure weather seal protection at the joints.

It is, therefore, an important object of the present invention to provide a sliding sash type of window assembly with improved means for mounting window panes in pairs in each of the sash members for the purpose above outlined.

It is also an important object of the present invention to simplify the arrangement of mounting pairs of frame members in each sash of a normal sliding sash window assembly.

A further object of the present invention is to provide an improved sliding sash window assembly that does not require the usual independentl formed and mounted storm sash.

3,427,747 Patented Feb. 18, 1969 Other objects of the present invention will be set forth in greater detail in the following description of a preferred embodiment, and reference will be made to the several views in the accompanying drawings, wherein:

FIG. 1 is an elevational view from the exterior of a typical sliding sash window assembly in which the present invention is incorporated;

FIG. 2 is a view similar to FIG. 1 but seen from the interior;

FIG. 3 is an elevational view of a window assembly in which the hingedly mounted frame members are shown in perspective view so as to illustrate the direction of movement and the accessibility that is provided by the preferred arrangement of components;

FIG. 4 is a greatly enlarged sectional view of the window assembly as seen along line 4-4 in FIG. 2;

FIG. 5 is a fragmentary sectional detail showing the hinge action of the frame members in each sliding sash;

FIG. 6 is a fragmentary view of a portion of a hinge which is embodied in the present improvement;

FIG. 7 is an enlarged fragmentary perspective view showing the components of and operating action for the latch means preferred for the hinged frame members; and

FIG. 8 is a fragmentary sectional view of the seal at the meeting rails of the upper and lower sash, as seen at line 88 in FIG. 2.

Referring now to FIGS. 1, 2 and 3 in particular, it is seen that the window assembly 10 includes an upper sliding sash 11 and a lower sliding sash 12. As can be noted in FIG. 3, the upper sash 11 is mounted in the outer slideway of the sash frame 13 while the inner sash frame 12 is mounted in a more inwardly disposed slideway. This arrangement is also shown in FIG. 4. It will not be necessary to describe in more detail the parts of the assembly which will permit sliding movement of the outer sash 11 and inner sash 12 as this is generally standard construction.

The present invention is concerned with the provision of a pair of frame members hingedly mounted in each sash. For example, in the outer sliding sash 11 there is provided a frame 14 which is considered the storm window frame and a similar frame 15 which is the normal interior window. These hingedly connected windows are shown respectively at 14 and- 15 in FIGS. 1 and 2. In a similar manner, the inner sliding sash 12 is provided with a storm window frame 16 and with an interior frame 17. These components are indicated in FIGS. 1 and 2.

In FIGS. 1, 4 and 5 it can be seen that the exterior or weather side of the window assembly is provided with weather seal strips 18 along the respective sides of the frames. Each of the weather strips 18 is formed with an enlarged marginal bead 19 so located on the sliding sash frame that the head 19 engages in a preformed surface 20 (see FIG. 5) of the

storm window frames

14 or 16 as the case may be. The respective seal strips 18 are suitably secured in position by screws or other means shown at 21 in FIG. 4. As is seen in FIGS. 4 and 8, there is a seal S provided between the meeting rails of the upper and lower sash, such seal comprising a first strip member 18a suitably attached to the rail 12a of the lower sash 12, and a cooperating strip 18b attached to the rail 11a of the upper sash. Consideration of FIG. 8 will serve to show the tongue on strip 18b fitting into the turned lip on the strip member 18a in order to effect the necessary seal closure.

A particularly important feature of the present invention is arranging the storm window frame and the interior window frame of each sliding

sash

11 and 12 for inward hinging movement so that the panes 22 in each such frame may be completely accessible from the interior of the building. This accessibility is accomplished by means of the continuous hinge assembly 23 shown to advantage in FIGS. 4, and 6. The hinge is formed with

opposite wing plates

24 and 25 and a center plate 26. These respective plates are formed to receive suitable pivot pins 27 that inter-connect the several plates. With a hinge of the type shown in FIG. 6, the plate 25 is preferably secured by suitable screws '28 to the window frame 11. The center plate 26 is then secured by similar screws 28 to the edge of the interior window frame 15, and the remaining plate 24 may then be secured by screws 28 to the edge of the exterior or storm window frame 14. In this manner, the plate 25 supports the pair of window frames 14 and when they are in the open position as shown in FIG. 5, while plate 26 supports the window frame 15. The preferred hinge assembly 23 is similar in its general structure to a continuous type hinge in that the hinge pins 27 extend the full length of the hinge, and the hinge itself extends substantially the full length of the edge of the

respective window frames

14 and 15. On inspection of FIGS. 4 and 5, it can be seen in what manner the preferred hinge 23 operates, and it is further pointed out that the hinge connection at pin 27 between

plates

24 and 26 forms an air leakage block inwardly of the exterior weather seal bead 19, while the hinge connection between plates and 26 is exposed at the interior of the assembly.

Turning now to FIGS. 2, 3, 4 and 7, there is shown in detail the latch assembly 30 for locking or releasing the storm window frame 14 and interior window frame 15 or the

corresponding window frames

16 and 17, depending on which sash is being manipulated. For purposes of this description, reference will be made in FIG. 7 to the

window frames

14 and 15 which are those hingedly mounted in the upper sliding sash 11. At a suitable place along the length of the side member 11a of the sash frame 11 there is provided a slot 31 which receives a suitable latch keeper member 32. The keeper is usually a metallic part to prevent the latch means to be described from digging into the wood in the case where the window assembly is of wood construction as illustrated. The storm window frame 14 at a place opposite the slot 31 is formed with a semicircular recess 33 which aligns itself with the keeper 31 in the sash frame 11. On the exterior of the frame 14 there is secured an angle plate 34 which has its leg 35 secured by screw means 36 such that the other angular leg 37 is positioned over the slot '33. The

legs

35 and 37 of the plate 34 are slotted as is indicated by the slot portion 37a and the cooperating and communicating slot portion 35a. Both of the

slots

37a and 35a communicate with the semicircular slot 33 in the window frame 14. The cooperating interior window frame 15 carries a second angle plate 38 for the purpose of operatively carrying a latch bolt 39 having an actuating handle 40 on the interior for operating the latch pin 41 on the exterior. The bolt 39 is operatively mounted by the angle plate 38 in a suitable bore 42 in the frame 15, the assembly generally being effected by inserting the bolt 39 through the bore 42 in the frame 15 and then mounting the latch pin 41 in the projecting end of the bolt 39.

In operation when the latch operating handle 40 is in the full line position, the latch pin 41 will be directed to pass through the slot 35a thereby permitting the storm window frame 14 and the interior window frame 15 to be brought into close abutment as is shown in FIG. 4. Since dotted line position (FIG. 7) which will rotate or swing the pin 41 to a vertically retracted position within the semicircular slot 33 of frame 14. At this time the

frames

14 and 15 are interconnected and cannot be separated, but the frames can then swing as a composite unit about the hinge pin 27 as an axis to the closed position where the slot 37a of the angle plate 34 lines up opposite the slot 31 in the sash 11. Now the handle 40 may be swung again to the full line position and the pin 41 will swing inwardly of the slot 31 and bear upon the slot liner means 32. As can be seen in FIG. 4, the width of the strip seal 18a is such that the inner end of the bolt 39 clears the strip when either sash is moved to open the window in a normal manner.

It can now be appreciated that the present window assembly of sliding sash has been clearly improved by the preferred arrangement of hingedly mounting inner and outer frame members in each of the window sash so that accessibility is immediately possible to the outside surface of the window panes, and storm protection is also provided in a novel and exceedingly simple manner. In the present assembly it is shown that a simple weather seal may be used so that leakage is completely avoided.

A very important advantage of the present improvement is that there is only a minor reduction in the size or area of the window panes that are accommodated in the preferred embodiment over the slightly increased size or area of normal window panes that would be accommodated in the unimproved sliding

sash

11 and 12.

While a preferred embodiment of the present invention has been shown and described in the foregoing specification and drawings, it is appreciated that changes and modifications may be suggested to those skilled in the art from the foregoing, and it is the intention to cover all such changes and modifications within the scope of the appended claims.
