No. 334,801 Claims. (Cl. 16tl l07) This invention relates to window constructions and is more particularly concerned with improvements in a window of the type having a Venetian blind incorporated therein. n

It is a general object of the invention to provide 1mprovements in a window which is pivotally mounted in an opening in a wall and which is constructed so as to form a compartment for a Venetian blind with the blind mounted therein so that the window can be pivoted to a reversed position without interfering with the blind.

It is a more specific object of the invention to provide a window st-ructure which comprises a sash mounted on a concealed vertical .pivot so that it may be readily reversed for cleaning and which incorporates a compartment between spaced panes for mounting therein a Venetian blind with a control know which is readily accessible for tilting the slats and with concealed pull cords for raising and lowering the blind, the one side of the sash comprising a glazed-in side hinged frame providing ready access to the compartment in which the blind is mounted.

It is another object of the invention to provide a window construction which comprises a supporting frame adapted t-o be mounted in an opening in a wall, a sash assembly mounted in the supporting frame on vertically aligned, concealed pivots with weather stripping which is airtight when the assembly is reversed for cleaning and with the assembly comprising a rectangular frame of substantial thickness formed by hollow frame Imembers and providing glazing channels for receiving a glass pane which forms a normally outside face thereof and a door-like inside fframe which is hinged to the tubular frame and provided with glazing channels for a pane of glass which normally forms an inside face thereof, and a Venetian blind mounted between the two glass panes and having operating cords which are concealed in the tubular frame with a slat tilting knob accessible on the inside of the tubular frame.

It is a further object of the invention to provide a window construction of the type described wherein the sash assembly is held in the supporting frame by key operated lock and latch devices permitting only authorized persons to reverse the window.

It is a still further object of the invention to provide a window construction of the type described wherein the -sash is .provided with means for permitting the circulation therein of outside air so as to reduce the tendency of moisture to condense in the blind accommodating compartment formed between the two glass panes when the inside iframe is closed.

These and other objects and advantages of the invention will be apparent from a consideration of the window structure which is shown yby way of illustration inthe accompanying Adrawings wherein:

Referring to FIGURES l to 4, there is illustrated a window construction l0 which incorporates the principal features of the present invention and which is adapted to be mounted in an opening ll in a vertically disposed wall l2 of a building. The window It) comprises an outer support frame 14 in which there is mounted for pivotal movement a sash assembly l5. The outer supporting frame I4 is rectangular and formed of connected end frame members 16, I7 and side frame members I8, 19 of aluminum, Stainless steel or the like. It extends about the periphery of the opening Il `so as to present inside edge surfaces I6', 1'7, I8 and I9' of substantial Width. The top and bottom end frame members I6 and i7 are provided with vertically aligned apertures in the inside edges lo and I7 which are adapted to receive bearing forming members 2li and 2l for accommodating pivot forming members Z2 and 23 extending from the sash assembly l5 and located midway between the sides I3 and I9 of the supporting fra-me lli.

The sash assembly l5 comprises a -main frame of rectangular shape having top and bottom end members 2d and 25 which extend between and connect the ends of

side frame members

26 and 27. The frame members Z4, 25, 26 and 27 are of hollow construction, preferably formed of extruded metal, such as aluminum, stainless steel or the like, with a generally rectangular cross section. The `

frame members

24, 25, 26 and 27 are connected so as to present peripherally extending exterior edge faces ld, 2:3, 26 and Z7 which are slotted at Sti and 3l for accommodating a pair of

compressible weather strips

32 and 33 which extend `uninterruptedly about the entire periphery of the frame and which engage with the confronting surfaces I6', 17', I8', I9 of the outer frame ld when the inner assembly I5 is in the plane of the frame Id. The

weather strips

32 and 33 are effective for sealing the sash assembly l5 in the outer support frame la in either the normal or the reverse position of the assembly I5 so long as it is swung into the plane of the outer frame Id so that the surfaces lo', I7', I', I9 and 245', 25', 26', 27 are in confronting relation.

The upper frame mem er 2@- of the sash assembly I5 has an aperture 34?- in which the upper pivot pin 22 is seated in fixed relation. The lower frame member 25 has an aperture 35 in which there is seated a bearing and spring housing member 36 for receiving the lower pivot pin 23. The pin 23 has a stem 37 of reduced cross section which extends into the housing forming upper portion of the member 36 and on which a compression spring 33 is seated with its one end bearing against the inside surface of the flange at the top of the housing forming member 36 and with the other end bearing against the shoulder itl on the pin 23 so that this pin is slidably mounted in the housing 36 and urged by the compression spring 38 into position to engage in the bearing 2l in the outer supporting frame I4.

The

frame members

24, 25, 26 and 27 of the sash assembly 15 are formed to provide on the outside face of the assembly 15 a glazing channel 41 in which the margins of a pane of glass 42 are seated with a suitable seal forming glazing assembly 43 for retaining the pane 42 permanently in place therein.

The

frame forming members

24, 25, 26 and 27 of the sash assembly 15 are formed with a continuous recess 44 extending about the inside edge of the frame on the inside face thereof and a glazed panel assembly 45 is mounted by means of a pair of concealed hinges 46 so as to swing about an axis extending along the inside edge of the one vertical side frame member 26. The panel assembly 45 is of rectangular shape and is provided with a glazing channel 47 in which the margins of a pane of glass 48 are seated with a suitable glazing assembly 58 to hold the same therein. The side and end frame members of the panel assembly 45 are formed so as to provide a peripheral flange 51 which extends into the recess 44 in the

frame members

24, 25, 26 and 27 and a compressible sealing member 52 is mounted in a channel 53 which extends continuously about the inner edges of the frame members in panel assembly 45. Portions of the hinges 46 may be formed integral with the one side frame member as shown in FIGURE 4.

A Venetian blind 55 is mounted within the compartment formed by the

frame members

24, 25, 26 and 27, the outer glass pane 42 and the hinged inner glazed panel 45. The blind 55 is of conventional construction having a series of slats 56 mounted on

parallel cords

57 and 58 extending between lower and upper cross bars 59 and 60, the latter constituting the bottom forming plate member of an upwardly opening housing 61 which is of channel shaped cross section and which is secured to the inside along the top sash frame member 24. The blind 55 is provided with the cords 62 (FIGURES 3 to 5) for raising and lowering the same and the cords 63 for tilting the slats. The cords 62 are attached at one end to the bottom cross bar 59 and extend through grommets in the housing member 60, through the housing and out of the one end thereof through a short length of flexible conduit which is turned down beneath a guard plate 64 (FIG- URE at an upper corner of the sash frame. A hook 65 is provided near the bottom of the sash frame member 27 on the inside surface, where it is concealed when viewed from the front of the window, for attachment thereto of a connecting ring 62 on the ends of the cords 62 when the blind is raised as shown in FIGURE 5 in order to hold the blind in a raised position.

The slat tilting cords 63 extend through grommets in the housing member 60 and are attached to a metal tape 66 which is looped around a pulley 67 at one end of the housing 61 so that the ends thereof have a limited travel in a path alongside the front and back walls of the housing 61. Pullcords 63' are attached to the ends of the metal tape 66 and extend through short metal conduits at the end of the housing which extend through the guard plate 64 and also through suitable apertures provided in the inside wall of the side frame member 27. A pair of pulleys or drum members 68 (FIGURES 6, 7 and 9) are mounted side by side on a small shaft 68' which is journaled in the inside wall of the sash frame member 27 and provided with an external knob 69 for turning the same. The two ends of the cords 63 are coiled in reverse directions about the pulleys 68 and secured so that turning the knob will wind the one end of the one cord 63' in one direction and unwind the end of the other cords 63 in the opposite direction for tilting the slats 56 as desired.

Latch assemblies 70 (FIGURES 5 to 7) are mounted in the frame side member 27 near the bottom and top thereof for latching the glazed panel 45 in closed position. Each of the latch assemblies 70 comprises a supporting bracket 71, a latch arm 72, pivotally mounted on the bracket at 73 and having a linger piece 74 which is accessible for operation through a finger slot or opening 75 in the outer edge of the frame member 27. The other end of the latch arm 72 is adapted to be swung into engagement with a slotted keeper 76 extending inwardly of the frame of the panel 45. The sash frame member 27 is slotted at 77 to accommodate the keeper 76. The latch lingers 74 are, of course, accessible for operation only when the sash assembly 15 is pivoted out of the plane of the supporting frame 14 as shown in FIGURE 2. The entire sash assembly 15 may be locked in closed position by means of a barrel-type lock having a pivoted lock bar or finger 80 which is adapted to be received, when turned to locking position, in a keeper slot (not shown) in the sash member 19 of the outer frame 14. The lock assembly 78 preferably includes a key of the type which is removable from the lock only when the lock is in operative position.

In order to eliminate any tendency for moisture to condense in the blind accommodating compartment when the sash assembly 15 is in the normally closed position due to temperature and moisture differences between the air on the inside and the outside of the sash, provision is made for circulation within lthe compartment of the outside air which is normally cooler and drier than the inside air. As indicated in FIGURE 10 weep holes are provided at 81 in the outside wall 82 of the support frame bottom end member 16 and at 83 in the inside wall which forms the inside edge 16 of the hollow frame member 16. The weep holes 83 :are in the central area of Ithe edge 16 so as to lie between the

weather seals

32 and 33 on the sash assembly 15 when the latter is in the closed position. Vertically disposed vent tubes 84 are provided in the -hollow bottom frame member 25 of the sash assembly 15 and grommets 85 are disposed in holes provided in the inside wall 86 of the hollow top frame member 24. The outside wall 87 of the ltop sash frame member 24 is provided with slots 88 which open into a drip cap 89 extending along the top portion of the outside glazing channel formation 41. The drip cap 89 is vented at its ends with the vent openings covered by a screen as indicated at 90. The number of weep

holes

81, 83, vent -tubes 84, grommets and slots 88 and their location will be determined according to the amount of outside air circulation desired within the sash :assembly 15.

The operation of the window will be obvious from the description of the structure thereof. It may be unlocked and the sash assembly 15 pivoted to open position as shown in FIGURE 2 which renders the latches 72 accessible for opening the hinged panel 45 to raise or lower the Venetian blind. The vertical pivot arrangement permits reversing the sash assembly 15 for cleaning purposes with the two frames being airtight when in either normally closed or reversed position. The slats in the Venetian blind may be readily adjusted by turning the knob 69 without any other adjustment of the window.

While particular materials and specific details of construction have been referred to in describing the form of the window illustrated, it will be understood that other materials :and equivalent details of construction may be resorted to within the spirit of the invention.
