Reynaud, Grosse Pointe Park, Mich. Application February 13, 1956, Serial No. 565,133 10 Claims. (Cl. 20-42) This invention relates to improved awning type window structures and more particularly, but not exclusively, to an operating and locking mechanism for such window structures.

One important object of the invention is to provide a window structure having vertically swingable sashes arranged to swing about horizontally disposed hinge pins so as to permit the sashes to be moved to various positions of adjustment and to provide improved operating and locking means therefor so constructed as to facilitate the operation of such sashes and the locking thereof in their closed position.

This and other objects are accomplished by the practice of the instant invention, one feature of which includes a window structure comprising a frame having side and end members and a sash swingably mounted upon the frame and adapted to hold a sheet of glazing material. A slidable actuating bar is positioned in a recess within the frame and supports the sash upon a pivot. The sash is also swingably secured to the frame by a link pivoted at one end upon the sash and pivoted at the opposite end upon the frame. The link includes ahook portion at the end thereof pivoted upon the sash. The actuating bar carries a pin rigidly mounted thereon and projecting therefrom and positioned selectively to.

engage and to disengage the hook portion of the link when thesash is swung into its closed position Within the frame and the bar is moved in a predetermined direction.

The invention will be described in greater detail in connection with the accompanying drawings of which:

Fig. 13 is a sectional view of the structure shown in Fig. 1 taken along a section line (not shown) closely adjacent to and looking in the opposite direction from the section line 22. This figure shows the structure in a different operative position from that illustrated in Fig. 1.

In the drawings, wherein for the purpose of illustrating the invention there is shown a preferred embodiment thereof including the operating mechanism for the sash members and the various parts incident thereto, the reference character 20 will be generally employed to designate a window frame formed of channel bars or the like including side, top and end bars arranged with their ends connected together in rectangular relationship. The side bars 23 and 25 are of generally channel shape as the side bar 23 shown in detail in the drawings. The side bar 23, and also the bar 25, includes an outer wall 22 shaped to form a separate locking channel 24 having enclosing flanges 26 and facing inwardly toward the main channel of the side bar. The side bars 23 and 25 are adapted to be rigidly secured as by screws or bolts passing therethrough to a structural member of a wall opening in a building or the like thereby securing the frame rigily in place.

The window frame 20 is provided with a series of vertically slidable and swingable sashes 30 and 32 which are rectangular in construction and may be formed of either Wood or metal moldings as desired. The instant description will be concerned with wooden sashes although it is to be understood that metal sashes may be substituted therefore according to known techniques. Glass window panels 34 are installed in the sashes and may be held in place conventionally as by molding strips, glazing triangles and putty (not shown). Each of the sashes includes two frame members 36 and 3S fastened together in overlapping relationship to provide a sealing face 44) extending along the sides of the sash. When the sash is in its closed position, the face 40 abuts against a resilient gasket 42 held in the outer wall 22 of theside bar by means of a channel groove 44 as shown in Fig. 4. The inner frame member 38 of the sash closes against a gasket 48 similarly held in a channel 50 in the inner wall 46 of the side bar.

A slide bar 52 (Figs. 1 and 6-9) is slidably mounted within the channel of the side bar 23, shown in Fig. l at the right-hand side of the window, although if desired it, together with its enacting elements, maybe transposed to the left-hand side of the window to operate in an structure comprising only two sashes in vertical array,

the invention is equally applicable to window structures including an array of one, three or more sashes. If the structure includes only one sash, it will be operated in the manner hereinafter to be described with respect to the lower sash 32. If the window includes more than two sashes in vertical array, all the sashes except the bottom one would be connected and operated in an identical manner to the upper sash 30.

The sashes are pivotally mounted on the slide bar by means of brackets 68 and 69. Each of the brackets includes a dog-leg portion 72 extending upwardly and inwardly toward the interior of the window structure. The brackets may be secured to the sashes by any convenient means such as the screws 70. Pivotpins 74 and 75 extend through holes in the dog-leg portions of the brackets to fasten the brackets to the slide bar. These pins pass through the brackets and the slide bar 52 into the locking channel 24 in the wall 22 (Fig. 6) where they are retained and locked by means of slidable locking plates 80. These pins 74 and 75 are the principal retaining means to hold the slide bar 52 in its operative position within the channel of the side bar 23 of the window frame. The lower and upper sashes are, additionally, linked to the side bar 23 by the links 84 and 86, respectively. The link 86 attached to the upper sash includes a locking hook portion 87 and is pivoted at one end upon the upper sash 30 by one of the screws 70. At its opposite end it is pivoted upon a screw 88 at a fixed point along the side bar 23. The link 84, associated with the lower, or bottom sash 32, is pivoted at one end upon a bracket screw 70 attached to the sash frame. The other end of this link 84 is pivoted upon a screw or pin 90 at a fixed point along the side bar 23.

It will thus be seen that the sashes are mounted so as to be responsive to a sliding motion imparted to the slide bar 52. i. e., movement of the slide bar causes the sashes to swing about axes defined by the screws 70 that secure the ends of the respective links 84 and 86, While simultaneously the axes of the sashes swing about the pivot pins 88 and 90 by which the links are secured to the side bar.

The slide bar 52 is actuated by a crank and worm mechanism generally designated 54 to which it is connected by a draw bar 51. The crank and worm assembly forms no part of the instant invention and may be of conventional construction. It may include, for example, an operator crank 92 which turns a worm (not shown) to drive a worm wheel (not shown) to turn the actuating crank 56. The actuating crank 56 is pivotally connected by a screw 58 or any other suitable means such as a rivet to one end of the draw bar 51. The slide bar 52 is connected to the other end of the draw bar 51 by means of the pin 75 heretofore described that also retains the lower sash bracket 69 and the slide bar 52 in position.

The bracket 68 that holds the upper sash 30 is fitted with an auxiliary pin 94 closely adjacent to the pivot pin 74 in the dog-leg portion of the bracket. This pin, as shown in greater detail in Fig. 8, projects from the bracket into a shaped, lost motion and cam aperture 96 in the slide bar. This aperture serves two purposes. First, it permits a predetermined movement of the slide bar independently of the movement of the sash so that, as hereinafter described, the slide bar may be moved downwardly to unlock the sash before it exerts a downward force upon the pivot pin 74 of the sash. Secondly, it is shaped to limit the movement of the pin combination (the pivot pin 74 and the auxiliary pin 94) to hold the window rigidly in a fixed position at any point in the travel of the slide bar.

The link 86 by which the upper sash 30 is connected to the side bar 23 of the window frame includes a hook portion 87 at the end of the link that is pivoted upon the sash. This hook is shaped to cooperate with a pin 98 mounted upon the slide bar and shown in greater detail in Fig. 9. The pin 98 is secured within the side bar retaining channel 24 of the window frame by means of a slidable plate 100 and it, also serves to retain the slide bar 52 in its desired position within the side bar channel.

A locking device, generally designated 102 and shown in detail in Figs. through 12, is disposed in the opposite side bar 25 of the window frame from the slide bar. This lock includes an auxiliary link 104 slidably mounted within the channel of the left-hand side bar 25 of the window frame. The link 104 is pivoted upon a lever 106 by a rivet or pin 108. The lever 106 has a handle portion 110 which projects through a slot in the Wall of the side bar 25 into the interior of the building in which the window is mounted. The lever is pivoted to the frame and held in alignment as by the screw 112 so that a swinging d movement of the handle 110 produces generally rectilinear movement of the link 104. A sash supporting link is connected between the lower sash 32 and the side frame bar 25. This link 105 is generally similar to the link 86 connected to the opposite side of the upper sash 30 and has a cam-shaped hook portion 107 at its upper end adjacent to its pivot point 109 upon the sash. A pin 114 projects from the side of the link 104 at the upper end thereof and in a position to be engaged by the hook 107 when the sash is closed and the lever handle 110 is raised. The hook 107 and pin 114 thus lock the lower sash firmly and rigidly in a closed position. The hook is preferably formed as a cam with sloping sides so that as it engages the pin it tends to draw the sash inwardly toward the frame to insure a weather-tight seal between the sash and the gaskets 42 and 48. The sides of the sashes opposite from the crank and worm mechanism 54- and adjacent to the left side bar 25 may be supported by a slide bar and link assembly generally similar to the assembly heretofore described except that an actuating crank and draw bar need not be included. The sashes generally are sufficiently rigid to maintain themselves in alignment.

In operation with the relative parts positioned as shown in Figs. l-l2, the window sashes 30 and 32 are in a fully closed position and are locked against unauthorized opening from the outside of the building by means of the interengaging hooks and pins, the hook 87 being associated with the upper sash and engaging the pin 98 as shown in Fig. 2, and the hook 104 being associated with the lower sash and engaging the pin 114 as shown in Fig. 12. In this position the slide bar 52 is in its fully raised position and the window sashes are completely closed relative to the frame 20.

Should it be desired to open the window sashes 30 and 32, the slide bar 52 may be moved downward in a vertical direction by turning the operator crank 92 which is connected through the worm and wheel assembly 54, the actuating crank 56 and the draw bar 51 to the slide bar. Before the operator crank is turned, however, the locking lever 106 must be depressed to release the pin 114 on the lower sash from engagement with the hook 104 in order to free the lower sash 32. As the slide bar descends the lower sash 32 starts to open and, simultaneously, the pin 98 is withdrawn from engagement with the hook 87 of the upper sash link 86. As the pin is drawn free of the restraining edge of the hook, the edge of the slide bar defining the aperture 96 is brought into contact with the pivot pin 74 that holds the upper sash bracket 68. Further downward movement of the slide bar 52 moves the pivot pins 74 and 75 of the two sashes downwardly and in cooperation with the links 84 and 86 forces the sashes to swing outwardly. When the slide bar reaches its fully extended downward position, the relative parts are in the position shown in Fig. 13 and the sashes are substantially fully open in an almost horizontal position.

The links 84 and 86, it should be noted, are pivoted upon the respective sashes at points closer to the bracket pivots 74 and 75 than to the lower edges of the sashes. Thus, the sashes are unbalanced so that their weight tends to close them and the force exerted by the sashes upon the pivot pins 74 and 75 is in an upward direction when the sashes are in an open position.

When it is desired to close the sashes 30 and 32, the slide bar 52 is moved upwardly by turning the operator crank in its reverse direction to swing the actuating crank toward its vertical position. The weight of the sashes themselves assists in this operation so that relatively little force is required of the actuating crank. The upper sash 30 closes first as the slide bar is raised after which the lower sash closes and the hook 87 is engaged by the pin 98 to lock the upper sash in its closed position.

It will thus be seen that the improved mechanism herein described provides a window structure wherein all of the operative parts are concealed and which is relatively simple and rugged in construction tion.
