9 Claims. (Cl. 74-491) This invention relates generally to operators for the operating mechanism for pivoted closures. and refers more particularly to an operator for jalousie operating mechanism. One of the essential objects of the invention is to provide a construction which is mountable in operative condition on either the right hand or left hand side of a jalousie frame and which is quickly exchangeable from one side to the other. It is a further object to provide a construction which may be used as a replacement for other types of operators and without disfigurement in appearance. Still further it is an object to provide a construction which is composed largely of cast aluminum alloy elements and which has all the required strength for taking care of the stresses to which it is subjected.

With these objects in view the invention consists in the construction as hereinafter set forth.

In the accompanying drawings:

Figs. 1 and 2 are vertical sections through a jalousie window and showing the end members for the panes thereof in opened and in closed positions respectively.

' Fig. 3 is a fragmentary front elevation of the jalousie window illustrated in Figs. 1 and 2.

Fig. 9 is a fragmentary sectional elevation of a side rail, taken from the inner side thereof, and showing the actuating bar for the jalousie operating mechanism in locked position.

Fig. 10 is a detached enlarged front elevation of the member K and nut K constituting a part of the adjust-- K and actuating bar G with a portion of the latter broken away.

Jalousie windows are controlled by various types 'of operators, some of which are movable in a vertical slot in the frame. In my invention the mechanism is actuated by a rotatively movable lever handle locatedfin a convenient position on the jalousie frame. If such construction is used as a replacement for another type of operator, and one in which the jalousie frame is slotted, it is desirable to conceal this slot. I havetherefore devised a construction in which the operator unit is mounted on a side rail of the jalousie frame to engage andconceal a slot or cutaway portion therein and to form a rigid attachment to the side rail. As above stated, the operator is composed largely of cast aluminum alloy elements, but as it is subjected to some considerable stress in its operation, it is reinforced by stronger metal.

Generally described, the operator includes a cast aluminum alloy lever handle A pivotally mounted on a bearing member C having a portion C fitting within a slot or cutaway portion B in a side rail B of the jalousie frame. The side rail B is formed of an extruded aluminum channel bar which received and conceals portions of the operating mechanism and the bearing member C for the lever handle A is mounted on an angle flange B of said side rail adjacent to a transversely extending web portion B thereof. To impart the requisite strength to the handle A, it has cast within a hub portion A thereof a polygonal pin D that is preferably hexagonal.

and is formed of harder metal. Such pin D is coaxial with the hub portion A has a polygonal portion D- extending outward beyond the same and constituting an endwise extension thereof. The pin D has a portion D of reduced diameter within the hub portion A, and a part 8 of said hub portion encircles the reduced portion D and forms an anchor for holding said pin D from axial displacement. Beyond the polygonal portion D' is an end portion D that is further reduced in diameter 7 polygonal portion D of the pin D, as just described, a I

torque transmitting connection is formed between the handle A and said rock arm F. The bearing member C is of a length somewhat greater than that of the slot B in the rail B and has at opposite ends thereof portions C which overlap the side rail B and are attached thereto by screws C However, the portion C within the slot B in the side rail B will receive the maximum operating stresses and not the screws C To mount the handle A on the bearing member C projecting polygonal portion D' of the pin D is first inserted from the outside of the side rail B into the bore C bushing E isthen sleeved upon the polygonal portion D of said pin from the inside of the side rail B and is held against displacement by a nut D engaging the threaded end portion D The rock arm F is connected by a substantially aligned flat actuating bar G to the jalousie operating mechanism. The construction of the latter is not a part of the instant invention, but generally described, is of the following construction:

The separate panes H, H of thejalousie are mounted in metallic end members I which are pivotally attached at I to the side rail B. Actuating arms I extend on the opposite side of the pivots and are connected to the back of a channel-shaped common connecting bar J. Thus a movement of said bar I longitudinally WilLSiiHlll Patented Mar. 2 9', 1960 The scription of the jalousie, its connection to the operator.

is through the actuating bar G, the lower end of which is pivotally connected at 10 to the rock arm F, while its.

upper end is pivoted at 11 to an adapter member K mounted on the connecting bar J. Thus the rocking movement of the handle A will be transmitted through the rock arm F, actuating bar G, and member I to the connecting bar I to operate the end members I and panes H and H of the jalousie window.

As my improved operating mechanism is sometimes used as a replacement for that of a previously installed jalousie, it is desirable to provide adjustment for the connections. Thus, as shown in Fig. 11 the connecting bar I may have a bore J therethrough for engaging a pivot of the old operator and this bore is utilized for the attachment of the member K. However, its position may not be right to fit the new installation. I have, therefore, provided a headed pin K having a cylindrical portion 12 for engaging said bore J wherever located, and having a threaded shank K for passing through a longitudinally extending elongated slot K in the member K. A nut K is on one side of the member K beside a longitudinally extending flange K thereof which holds said nut K from turning while guiding the movement of the nut K lengthwise of the flange K and thereby guiding the pin K lengthwise of said elongated slot 5?. The nut K is provided at one side thereof with a cylindrical axial extension K which is initially inserted through a circular opening K at the upper end of the slot K and then engages the elongated slot K This extension K has an annular groove K therein that receives a guide flange K that extends along the edges of said slot K at opposite sides and at thebottomthereof, but terminates below said circular opening K Thus the .nut K may be assembled with the member K by first inserting the cylindrical extension K in the circular opening K and then moving the extension K longitudinally of the slot K so that the groove K will receive the guide flange K To prevent accidental disengagement of the nut K from the member K after engagement of the annular groove K with the flange K the upper edge of the opening K is pinched or otherwise distorted to provide a projection K that selves as an abutment for the cylindrical extension K and effectively prevents subsequent registration or alignment of said cylindrical extension K with the circular opening K".

However, the cylindrical extension K of the nut K is then free to slide lengthwise of the slot K between the projection K and the lower end of said slot K Thus the projection K prevents the return of the cylindrical extension K to its position of entry in the opening K".

Lugs

13 and 14 respectively at the upper and lower ends of the member K engage the channel of the connecting. bar I to guide the member K lengthwise of said bar I. The assembled parts just described, together with the other portions of the operator may be shipped as a unit to wherever it is to be installed and without danger of loss of any part through accidental disengagement} To attach the operator to the jalousie, the pin K is unscrewed and detached from the nut K so that said pin K may be inserted in the bore l" of the connecting bar I. The threaded shank K is then reengaged with the nut K which can then he slid lengthwise of the slot K to the proper location, and upon tightening the pin K the parts will be clamped in this assembled position.

When the end members I and panes H and H of the jalousies are closed it is desirable to lock them in such closed position. This may be accomplished as illustrated in Fig. 9 in which the rock arm F is turned by the lever handle A into a position where the upper end of the rock arm F abuts and is stopped by the web portion B of the frame rail B. In this position, the pivotal connection 10 has passed beyond its dead center, and the end members I of the jalousie window are in closed position. Actually, the arrangement of the bushing E and the

pivotal connections

10 and 11 is such that the upper end portion of the rock arm P will be held in contact with the web portion B after the pivotal connection 10 is beyond its dead center, and accordingly the actuating bar G and jalousie operated mechanism will be locked in closed position. A change of the operator from one side to the other of the jalousie frame, such for example from the right side to the left side of the jalousie frame, would cause the lever handle A to be in the wrong angular relation or position to the rock arm F, bearing member C, and side rail B. To avoid such result, the lever handle A and the rock arm F are relatively positioned with an included angle therebetween which is one-half the angular magnitude between adjacent sidesof the polygonal portion D of the pin D. Also the lever handle A and rock arm F are positioned relative to the poly onal portion D' of the pin D so that the lever handle A may be changed from a given angle on one side of the rock arm F to an equal angle on the opposite side thereof, by first disassembling or withdrawing the polygonal portion D of the pin D from the bushing E fixed to the rock arm F, then turning or shifting the lever handle A from one side to the opposite side of the rock arm P, so that the polygonal portion D will be turned or shifted from one side to the next, and then assembling or inserting the turned or shifted polygonal portion D' in the bushing E to retain the lever handle A in its new angular position relative to the rock arm F. The different positions in which the lever handle A and rock arm F may be assembled are illustrated in full and in dotted lines respectively in Fig. 6. Thus, the locations of the lever handle A in open and in closed positions of the end members I and panes H and H of the jalousie may be made the same relative to opposite sides of the frame when mounted on the right and left sides respectively thereof.

The operator as above described may be easily applied for operation of any jalousie construction. If it is used to replace operators which necessitate the slotting or cutting away of the side rails B of the jalousie frame, the bearing member C will cover such slot or cutaway portion. If the rails on both sides of the frame have been or are slotted, the bearing member C may be used to cover the slot in the side rail where the operator is mounted, and a solid blank L similar in shape to the bearing member C may be used, as illustrated in Fig. 8, for closing the slot or cut-out in the other side rail on which the operator is not mounted.
