21 Claims. (CI. 20-62) This invention relates generally to actuating means for an operating mechanism for pivoted closures, such as the pivoted panes of a jalousie window, and constitutes a continuation in part of my application filed June 3, 1957,

and bearing Serial No. 663,169, now Patent 2,930,251 dated'March 29, 1960.

One of the essential objects of the invention is to provide actuating means of the type mentioned that may be employed either in an original installation of the with the previously installed jalousie operating mechanism without alterations thereto.

Another object is to provide an adaptor structure wherein the adjustable means includes a nut and a cylindrical axial extension thereof that are slidable lengthwise of the body of the adaptor and have registering openings therein adapted to register with the former point of attachment for the previously installed actuating means, or with the proper predetermined point of attachment for the actuating means of an original installation.

Another object is to provide an adaptor structure wherein a part of the body of the adaptor is shaped to guide the nut during sliding movement thereof, and is operable to prevent the nut from turning during such sliding movement.

Another object is to provide an adaptor wherein the cylindrical axial extension of the nut is within and movable lengthwise of an elongated longitudinally extending slot in the body of the adaptor, and wherein the registering openings aforesaid in the nut and extension are adapted to receive a fastening element by which the adaptor may be attached to the connecting bar of the jalousie opertaing mechanism at the former point of attachment for the previously installed actuating means, or with the proper predetermined point of attachment for the actuating means of an original installation.

Another object is to provide an adaptor wherein the body is provided at one end of the elongated slot with a circular opening to permit original insertion or entry of the cylindrical extension into said slot via said' circular opening, and wherein a portion of the body at an edge of the circular opening is distorted after the cylindrical extension has entered the elongated slot via the circular opening, to provide a projection operable to prevent the cylindrical extension from subsequently registering with and being accidentally withdrawn from said circular openmg.

l'alousie windows are controlled by various types of operators, and certain of said operators are movable in vertical slots in the jalousie frame. In my invention, the mechanism is actuated by a rotatively movable lever handle located in 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 jailousie frame is slotted, it is desirable to conceal this slot. Therefore, I have devised a construction in which the operator unit is mounted on a side rail of the jalous1e frame to'engageand conceal a slot or cutaway portion therein and to form a rigid attachment to the side rail.

Generally described, the operator includes a cast aluminum alloy lever handle pivotally mounted on a bearing member 11 having a portion 12 fitting within a slot or cutaway portion 13 in a side rail 14 of the jalousie frame. The side rail 14 is formed of an extruded aluminum channel bar which receives and conceals portions of the operating mechanism, and the lever handle 10 is mounted at the front of said side rail on an angle flange 15 thereof adjacent to a transversely extending web portion 17. To impart the requisite strength to the handle 10, it has cast within a hub portion 18 thereof a polygonal pin 19, preferably hexagonal, formed of harder metal and coaxial with the hub 18. Such pin 19 has a polygonal portion 20 extending outward beyond the hub 18. The pin 19 has a reduced portion 21 within the hub 18, and a part 22 of said hub encircles the reduced portion 21 and forms an anchor for holding the pin 19 from axial displacement. Beyond the polygonal portion 20 is an end portion 23 that is further reduced in diameter and is threaded.

Non-rotatably sleeved upon the polygonal portion 20 of the pin 19 is a bushing 24 which interiorly conforms to and fits about the polygonal exterior of the portion 20 of the pin, but is externally cylindrical to rotate within a bore 25 in a hub 26 of the bearing member 11.

A rock arm 30 is rigidly secured to an outer projecting end portion 31 of the bushing 24, so that when the latter is engaged with the polygonal portion 20 of the pin, a torque transmitting connection is formed between the handle 10 and the rock arm 30.

The bearing member 11 is of a length somewhat greater than that of the slot 13 in the rail 14 and has at opposite ends thereof portions 32 which overlap the side rail and are attached thereto by screws 33. However, the portion 12 within the slot 13 in the side rail will receive the maximum operating stresses and not the screws 33.

To mount the handle 10 on the bearing member 11, the projecting polygonal portion 20 of the pin is first inserted from the outside of the side rail 14 into the bore 25. The bushing 24 is then sleeved upon the polygonal portion 20 of said pin from the inside of the side rail and is held against displacement by a nut 34 engaging the threaded end portion 23.

The rock arm 30 is connected by a substantially aligned flat actuating bar 40 to the jalousie operating mechanism.

The separate panes 41 of the jalousie are mounted in metallic end members 42 which are pivotally attached at '43 to the side rail 14. Actuating arms 44 extend on the opposite side of the pivots 43 and are connected to the back of a channel-shaped common connecting bar 45. Thus a movement of said connecting bar 45 longitudinally will simultaneously turn each of the members 42 on their pivots from the closed position where the pins 41 overlap each other as shown in Fig. 2, to the open position shown in Fig. l or vice versa as desired.

Without further description of the jalousie, its connection to the operator is through the actuating bar 40 that is pivotally connected at its lower end by a headed adaptor structure 48 mounted on the connecting bar 45.

A suitable socket 47 is provided in a longitudinal side edge of the body 54 of the adaptor structure 48 to receive the shank of the headed pivot pin 47. Thus the rocking movement of the handle 10 will be transmitted through the rock arm 30, actuating bar 40, and adaptor structure 48 to the connecting bar 45 to operate the end members -42 and panes 41 of. the jalousie. window,

As my improved actuating means for an 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 45 may have a bore 49 therethrough for engaging a pivot of the old operator, and this bore may be utilized for the attachment of the adaptor structure 48. However, its position may not be right to fit the new installation. Therefore, I have provided a headed pin 50 having a cylindrical portion 51 for engaging said bore 49 wherever located, and having a threaded shank 52 for passing through a longitudinally extending elongated slot 53 in the body 54 of the adaptor structure 48. In this connection, the former point of attachment for the previously installed actuating means, or the point of attachment for the actuating means of an original installation may be at the same or difierent locations in or on the connecting bar 45, as desired. As shown, only one point of attachment is illustrated, because both points above mentioned are at the same location.

A polygonal nut 56 having a threaded opening 56' therethrough is on one side of the body 54 beside a longitudinally extending flange 57 which holds said nut from turning while guiding the movement of the nut lengthwise of the flange 57, and thereby guiding the pin 50 lengthwise of the elongated slot 53. The nut 56 is provided at one side thereof with a cylindrical axial extension 58 which is initially inserted through a circular opening 59 at the upper end of the slot 53, and then engages the elongated slot 53. This extension 58 has an annular groove 60 therein which receives a continuous guide flange 61 that extends along the edges of said slot at opposite sides and at the bottom thereof below said circular opening 59. Thus the nut 56 may be assembled with the body 54 by first inserting the cylindrical extension 58 in the circular opening 59 and then moving the extension 58 longitudinally of the slot 53, so that the groove 60 will receive the guide flange 61. To prevent accidental disengagement of the nut 56 after engagement of the annular groove 60 with the flange 61, the upper edge of the opening 58 is pinched or otherwise deformed to provide a projection 62 that serves as an abutment for the cylindrical extension 58 and efiectively prevents subsequent registration or alignment of said cylindrical extension 58 with the circular opening 59. However, the cylindrical extension 58 of the nut is then free to slide lengthwise of the slot 53 between the projection 62 and the lower end of said slot. Thus the projection 62 prevents the return of the cylindrical extension 58 to its position of entry in the circular opening 59.

Laterally projecting lugs 70 and 71 respectively at the upper and lower ends of one side of the body 54 of the adaptor structure 48 slidably engage the channel of the connecting bar 45 to guide the body 54 of the adaptor structure lengthwise of said bar. A longitudinally extending flange 75 of the body 54 of the adaptor structure is spaced from and cooperates with the lugs 70 and 71 to guide the body 54 of the adaptor structure 48 lengthwise of the channel-shaped connecting bar 45. Such flange 75 slidably engages one longitudinal side edge of said connecting bar 45.

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 parts through accidental disengagement.

To attach the operator to the jalousie, the pin 50 is unscrewed and detached from the nut 56 so that said pin may be inserted into the bore 49 of the connecting bar 45. The threaded shank 52 is then re-engaged with the nut 56 after the latter has been slid lengthwise of the slot 53 to the proper location in registration with the bore 49, andupon tightening the pin 50, the

any jalousie construction.

adaptor structure 48will' be connected tothe connecting bar 45.

When the end members 42 and panes 41 of the jalousie 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 30 is turned by the lever handle 10 into a position where the upper end of the rock. arrn abuts and is stopped" by the web portion 17 of the side rail 14; In this position, the pivotal connection 46 has passed beyond its dead center, and the end members 42 of the jalousie window are in closed position. Actually, the arrangement of the bushing 24 and the pivotal connections 46 and 47 is such that the upper end portion of the rock arm 30 will be held in contact with the web portion 17 after the pivotal connection 46 is beyond its dead center, and accordingly the actuating bar 40 and jalousie operating mechanism will be locked in closed position.

A change of the operator from one side to the other of thejalousie frame, such for example from the right side to the left side of the jalousie frame, would cause the lever handle 10 to be 'in the wrong angular relation or position to the rock arm 30, bearing member 11 and side rail 14; To avoid such result, the lever hand1e-10- and the rock arm 30 are relatively positioned with an included angle therebetween which is one-half the angular magnitude between adjacent sides of the polygonal portion 20 of the pin. Also, the lever han- 'dle- 10- and rock arm are positioned relative to the polygonal portion 20 of the pin so that the lever handle 10 may be changed from a given angle on one side of the rock arm 30 to an equal angle on the opposite side thereof, by first disassemblying or withdrawing the'polygonal portion 20 of the pin from the bushing 24 fixed to the rock arm 30, then turning or shifting' the lever handle 10 from one side to the opposite side of the rock arm 30, so that the polygonal portion 2% will be turned or shifted from one side to the next, and then assemblying or inserting the turned or shifted polygonal portion 20 in the bushing 24 to retain the lever handle 10 in its new angular position relative to the rock arm 30; The different positions in which the lever handle 10 and rock arm 30may be assemblied are illustrated' in full and in dotted lines respectively in Fig. 6.

Thus, the locations of the lever handle 10 in open and in closed positions of the end members 42 and panes The operator may be easily applied for operation of If it is used to replace operators which necessitate the slotting or cutting away of the side rails 14 of the jalousie frame, the bearing member 11 will cover such slot or cutaway portion. If the rails on both sides of the jalousie frame have been or are slotted, the bearing member 11 may be used to cover the slot in the side rail 14 where the operator is mounted, and a solid blank 80 similar in shape to the bearing member '11 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.

In Figs. 14 and 15 respectively, I have shown a slightly modified form of adaptor structure wherein the body 81 is provided with transversely spaced longitudinally extending guide flanges 82 and 83 respectively thatslidably engage opposite longitudinal side edges of the channel-shaped connecting bar 45 to guide the body 54 of. the adaptor structure lengthwise of said bar. Other thaw this, the structure illustrated in Figs. 14 and 15 is similar to that shown in Figs. 10 to 13 inclusive.
