9 Claims. CI. 20-53 1 This invention relates to window construction and more particularly to an awning-type window which is hinged and adjustable to substantially any angular position.

It is a primary object of this invention to provide a window which does not require a sash.

Another object of this invention is to provide-a window which can be readily installed and made weathertight, rattle-proof, and tamper-proof with a minimum of effort.

A further object of this invention is to provide a window construction comprising a fewinexpensive ele ments which are readily assembled without requiring any special skills.

A still further object of this invention is, to provide: a window which shall require a minimum of maintenance in respect to cleaning and painting.

A further object of this invention is to provide, in connection with a window construction, simple means to adjust the opening of the window from withini doors and to hold it in any desired angular position including complete closure.

Still other. objects and attendant advantages of this invention will be manifest from the detailed description following in connection with the attached-drawingsawheree of Fig. 1 is a fragmentary outside elevation of a. window construction embodying the invention.

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

Fig. 3 is a vertical sectional view similar to Fig. 2 except takenwith the window opened.

Fig. 4 is a fragmentary detail of part of the window construction of this invention; 1

Fig. 5 is a plan view partly in elevation showing. the windowlocking means.

Fig. 6' isa detail view of. one of the: primary components of the window structure.

Fig. 7 is a perspective detail view of av hinge joint forming part of the window structure.

Fig. 8 isa perspective detailview of a stop used in the window construction;

Referring now to Fig. 1 a rectangular window frame is formed with vertical side members 10 and 11 and connecting horizontal cross members 12 and 13. The top cross member 12 and the'bottom'membert (not shown) extend to the full depth of the frame as seen best in Fig. 2; while theintermediate cross members suchas 13 are narrower indepth as shown, topermit the use of a single venetian blind or' roller shade for the" full height regardless of the number of window openings. It is understood that theframedescribed here providesa series of vertically'stacked window openings as is customary withawning-type windows.

Secured to the cross members 12 and 13 on the exterior thereof and extending horizontally for the full width of the frame are cap members 14. Shown best in Fig. 4, the cap members 14 have a cross-section in the form of a parallelogram and form with the respective cross members 12- and13- an acute angle pocket 15 running the full width of the frame for receiving the rounded top edge of a pane 16 preferably of bevelled plate glass in a mann-er to be described later.

The frame opening defined by members 10, 11, 12, and 13 cannot be relied on to furnish a true seat for the pane 16. Therefore metal'strips 17, 18, 19, and 20 having a=Z' section are secured-to the four edges of the window opening as seen-best in Fig. 4. These are pushed tightly outward against the inner surface of the glass pane 16in its fully closed position, and serve as stripping to form a weather-tight seal and thus compensate for dimensional irregularities usually found in the roughmilled frame members.

Secured to the central portion of the bottom edge of initurn; is thus urgedinto the hinge pocket 15 by a' spring member24. The member 24 is shown as a very stiff steel vwire spring having few extended small-diameter coils, with a view to making a high-rate spring with a limited extension represented by the fulllength of the wire. This makes practically impossible theunauthorized disengagement of. the pane-.lo from the pockct 15 by pulling down. onv the clamp 21 from the exterior of the window and. thusv promotes security consistent with minimum visual obstruction It is clear that/this member 24 may be. any resilient element: capable of transmitting the requiredforce:

A hingepiece. 25 is secured tothe top member 12 andthe. end of the. spring member 24 is anchored thereto by looping the wire end about ahinge pin 26 as shown best in.Fig.. 7. The. opposite. end of the spring member 24. is formed with. anenlarged upset portion 27 which fits within a threaded sleeve 28 as seen best in Fig. 6. A.screw-29 passesthrough an aperture in the stem portion.22 of the. clamp member 21 and is threaded into the sleeve 28'. It is evident that, by taking up on the screw 29,. the. required. tension may beestablished in the spring. 24. to seat the upper edge of the pane 16 in the hinge. pocket 15.w ith' the required force.

Hinged to the end of the stem portion 22 is a link 30: of fiatspring steel. to. the opposite end of which is hinged a flat operator member 31 which terminates in a turned-up portion 32 serving as. afinger hold for easy manipulation- Parts 21,.3ll,.and 31 thus form an articulated' window operator by means of which the pane 15 may. be adjusted. for. all'degrees of opening including fulllocked closure ina mannerto be described.

Secured to the intermediate cross member 13 by means of. screws 33 isv a. box like guide bracket- 34 which receives in sliding engagement, the flat members 21,, 3d, and 3.1 of the. articulated. window operator as seen best in Fig. 3; whichshowszthe window pane 16- in its fullyopened'positiom. Positioned Within thebracket 34 is an arcuate leaf spring. 35presenting its convex surface to the members. 22, 30,. and: 31' as. they slidethrough the bracket. 34. during adjustment of. thepane 16.

An eccentric actuator 36 is j ournaledin the bracket 34 and' is formed with-an exterior handle portion 37 and an interior offset portion 38. It will be seen that, with the handle portion 37 turned up, as in Fig. 3, the leaf spring 35 exerts only light pressure against the Window operator member 31 and it slides freely through the bracket. It will be noted that, at the hinge point between elements 30 and 31, there is a build-up of thickness due to the two elements plus the rivet head and this resists passage under the spring 35 to provide an important anti-slam feature. However, when the desired position of the pane is reached, the actuator handle 37 is turned down as shown in Fig. 2 whereby the offset portion 38 turns downward to urge the leaf spring 35 into frictional engagement with the members 22, 30, or 31, as the case may be, to clamp them securely against the cross member 13 thus securing the pane in that position. It will be noticed that this locked position of the actuator 36 corresponds to a locked-over-center condition of the offset portion 38, thus maintaining the actuator in locked position until released by manipulation of the handle 37.

A notch 39 is provided in the exterior edge of the cross member 13 as shown in Fig. 3 into which enters the clamp member 21 as seen in Fig. 2 when the pane is in fully closed position. This allows the pane 16 to fully seat tightly against the strips 17, 18, 19, and 20 in weather-tight engagement. It will be seen that, in this fully closed and locked condition, the head of the screw 29 cannot be reached from the exterior and the window is thus rendered tamper-proof.

When the operator elements 30 and 31 are pulled in to fully close the window they may be folded about their hinge points in nested fashion as shown in Fig. to prevent unsightly and inconvenient protrusion into the room and to provide additional locking security.

To prevent sidewise displacement of the pane 16 in the hinge pocket 15, stop pieces 40 shown in detail in Fig. 8 are secured to the side members 10, and 11 as seen in Fig. 1. These pieces may be formed of sheet metal and have a portion 41 which may be turned down to fit into the pocket and against each end of the top edge of the pane 16 serving as lateral stops therefor.

The three hinged elements 22, 30, and 31 provide an articulated, relatively stiff, semi-flexible member which bends to follow the arc of the pane 16 as it is moved to various angular positions. Further, the three elements 22, 30, and 31 represent the optimum number of parts to give the required flexibility consistent with lateral stability and convenient disposition of the parts in closed position. A larger number of parts would destroy lateral stability while a smaller number would be inconvenient as member 31 would become unduly long for a given window opening. The removal of the pane 16 for cleaning, painting, or replacement is readily accomplished by loosening screw 29 to release the tension in the wire 24 to the point where the pane may be pulled down and disengaged from the hinge pocket 15. The cap member 14 provides a weather-tight seal against entry of wind and water at the top edge of the pane in all positions of the window.

A screen 42 (or storm window) may be readily inserted in the window frame using the strips 17, 18, 19, and as positioning stops as seen best in Figs. 2 and 3.

While the window construction shown is described as preferably employing a glass pane without a sash, this invention is not to be construed as so limited, but includes the form of construction in which a sash may be used if desired.

From the above it will be evident that the constructional elements of this invention provide a fully adjustable window which may be readily constructed from a few simple parts with ordinary skill in assembly, with insurance against leaking, rattling and tampering and with minimum requirements as to servicing.
