14 Claims. (Cl. 20-42) This invention relates to windows and more particularly relates to awning type windows having improved locking devices.

Awning type windows,that is windows which pivot about a horizontal and generally vertically shifting axis, have long been popular for the high degree of ventilation and illumination which they provide and for the generally airy decor which they lend to a room or porch. Most such windows comprise a plurality of windows in a single window frame, with a common operator for all windows. Numerous different operating and locking arrangements have been used and, while the window crank operator normally controls all of the windows in a single frame, the lowermost or the uppermost window is frequently moved differently than the other windows in order to provide proper locking and sealing. Operating and locking arrangements thus have become quite complex and, even in those instances where the windows are made of wood, have become quite costly. This increasing complexity has led to a certain amount of equipment failure and this in itself has militated against a more widespread use of such windows. 7

It is accordingly a primary object of the present invention to provide awning type windows which utilize a simple operating and locking arrangement and which are relatively economical to produce.

It is another object of the invention to provide an improved awning type window which is simple and rugged in construction and durable in use.

It is another object of the invention to provide an improved awning type window having an improved closing and locking device associated therewith. I

It is a still further object of the present invention to provide an improved locking device for awning type windows.

These and further objects and advantages of the invention will become more apparent upon reference to the following specification and claims and appended drawings, wherein:

"ice

Figure 10 is a vertical cross section of the lock taken on the line 1010 of Figure 9;

Figure 11 is a further vertical cross section of the lock taken along the line 11--11 of Figure 9; and

Figure 12 is a plan view, partially in section, showing the top of the glass frame.

Referring to Figure 1 in the drawing there is shown generally at 10 a window consisting of a frame 12 and window sash 14. The window frame 12 consists of a pair of horizontal frame members 16 and 18 which are dadoed at the ends to receive vertical frame members 20 and 22. The window sash 14 comprises a glass frame consisting of a pair of horizontal frame members 24 and 26 and vertical frame members 28 and 30 in which a pane of glass 32 is mounted.

Referring to Figures 2 and 3, a pair of vertical strips 34 and 36 are mounted on the insides of vertical window frame members 20 and 22. These vertical strips 34 and 36 are possessed of an L-shaped cross section having smaller portions 38 and 40 and larger portions 42 and 44. Thelarger portions 42 and 44 are joined at their extremities by horizontal strips 46 which extend across the bottom and top of the window frame on the inside of horizontal members 16 and 18, as is best seen in Figures 3 and 4. The surface 40 of the vertical strips 34 and 36 and horizontal strips 46 form the face which the glass frame rests upon, and the large portions 42 and 44 of the vertical strips 34 and 36 are provided with sealing strips 50 and 52, as can be seen in Figure 2. These strips may be of any suitable type and are preferably of the neoprene or rubber variety having a tubular portion 54 and thin portions 56 which are received in slots in the vertical strips. Similar sealing strips are mounted on the back sides of the horizontal members 24 and 26 in the frame for the pane of glass 32 and these horizontal sealing strips cross the vertical sealing strips 50 and 52 to completely seal the window sash when it is in a closed position. I

The frame for the pane of glass 32 is supported within the window frame 12 by a pair of rollers 58 mounted on either end of the glass frame, as is best seen in Figures 5 and 12. Referring to those figures, it will be seen that the roller 58 is pivotally mounted upon a bracket 60 which is suitably screwed to the vertical member 28 and horizontal member 24 which are offset at 61. This olfset does not interfere with the air tightness of the window since the window is sealed by sealing strips inboard of the offset portions. This bracket 60 may also be seen in. Figures 3 and 4 wherein the frame for the pane of glass appears in dotted lines. The rollers 58 are received in channels 62 for vertical movement therein. The channels 62 are secured to the insides of the vertical members 20 and 22 in the window frame as by means of screws 64 and 66 as is best seen in Figure 3. The bottom screw 66 is provided with a projecting head, as shown in Figure -2, to serve as a stop to limit downward movement of the rollers 58. As can be seen in Figure 5, rollers 58' are located above the top of horizontal members 24 in the glass frame and the horizontal member 16 in the window frame is recessed at 68 to receive the rollers when the window is in a closed position.

Pivotally attached to the brackets 60 are a pair of actuator bars 70 and 72 associated with the operator 74 and lock-76 respectively, as is best seen in Figure 2. The actuator bars 70 and 72 are pivoted at 73 to the brackets 60 and at the other ends within the operator 74 and lock 76 respectively. The operator 74 is of a conventional sector and worm type and causes rotation of the actuator bar 70 upon rotation of the crank 78. As is well known with this type of window, this causes the glass frame to pivot about the rollers 58 while the rollers move vertically in the channels 62 to open and close the window. Referring to Figure 3, the window sash is shown in a partially opened condition, whereas in Figure 4 the window sash is shown in a closed position. The maximum open position is limited by the engagement of the roller 58 with the lowermost screw 66 in the channel 62, as is best seen in Figure 3.

While the principle of operation of this type of awning window has been known for some time, it will be apparent from the foregoing that the construction and hardware for operating this particular window is extremely simple and inexpensive. Each window sash is assembled as a separate unit and where it is desired to utilize a plurality of these window sashes one above the other, individual window sash units are stacked but are still opened and closed by their individual operators. This provides a high degree of flexibility for the designer and permits a widespread use of such awning windows, since the cost of the windows can be kept at a reasonable level. While the windows may be made of any materials wood is preferred.

Referring toFigures 6 through 11, there are shown details of the lock of my window. This lock consists of a casing 80 having one vertical edge 82 and a rounded edge 84. The casing has an outer wall 86 and an inner wall 88. A skirt 96 projects from the outer surface of the inner wall and the edge of this skirt engages the inner surface of vertical member 22 in the window frame when the lock is mounted as shown in Figure 2. The skirt comprises a vertical portion 92, shown in Figure 9, a horizontal portion 93, a rising portion 94, an arcuate portion 96, and a straight portion 98. Attached to the ends of the casing are a pair of mounting feet 100 and 102 which receive mounting screws 1G4 and 106, as is best seen in Figure 8.

Referring to Figures 8 and 11, a pivot pin 108 is mounted in an aperture in outer wall 86 and it is received in a bushing 110 in inner wall 88. The outer wall 86 is thickened at 122 -at the point Where the pivot pin 108 passes therethrough. Upon the pivot pin 108 there is mounted a locking plate 112 which is attached to the actuator bar 72. The locking plate 112 is generally sector shaped and is provided with a pair of converging edges 114 and 116, a generally arcuate end 118 and a locking lug 120. When the lock is mounted on vertical strip 36 the locking plate extends through a slot 109 therein.

Cooperating with the locking lug 120 is a locking cam 124 having a reduced diameter stud 126 at one end thereof. The stud 126 is received in an aperture in a thickened wall portion 128 on outer wall 86 and the other end of the cam is provided with an additional stud 129 attached to an operating lever 130 extending upwardly past inner wall 88. A suitable handle 132 may be provided on the lever 130. Referring to Figure 8, the cam 124 is cut away at 134. When the cam is in the position shown in Figure 8 the locking lug 120 engages the came 124 so that rotation of locking plate 112 or movement of actuator arm 72 is impossible. Thus in this position the window is locked. If the cam 124 is rotated until the cutaway surface 134 is in the position of the broken lines shown at 136, the locking lug 129 then clears the cam so that the window is unlocked and locking plate 112 and actuator arm 72 are free to move.

In closing the window, when the cam 124 is in the position shown by the broken line 136 and when the locking plate 112 is in the position shown by the broken line 138, rotation of the cam 124 in a counterclockwise direction positively cams the locking plate 112 into the position shown by the solid lines in Figure 8, wherein the window is completely locked. This. positive camming action permits tight sealing of the window and assists the operator in closing the window. This is important since the position of the actuator arm of the operator during the last few degrees of closing is such that it is ditficult to exert adequate force to obtain a tight seal. The lock shown in Figures 6 through 11 thus not only serves its function as a secure lock for the window, but also aids in closing and Sealing the window.

Referring to Figures 2 and it will be seen that when the lock is mounted in position on a window there are no pivot pins extending outwardly therefrom so that they might be bent and the unit damaged. Thus the pivot pin 124 on which lock operating lever 130 is mounted 7 is completely concealed. The arm 130 further extends out from the lock adjacent vertical member 22 so that it is absolutely impossible to bend the lever in such a manner as to damage the pivot pin. Movement of the lever is limited by horizontal position 93 and rising position 94 of skirt 90, as may be seen in Figure 9.

The window and lock of this invention are quite simple in construction, low in cost, and relatively easy to assemble. The lock is rugged and diflicult to damage and serves the dual function of locking the window and moving it into a position for locking.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
