Int. Cl. EOSf 17/00; E06b 7/08; Gg 5/06 US. Cl. 74--528 4 Claims ABSTRACT OF THE DISCLOSURE A lever type operator for jalousie windows which opens and closes jalousie louvers by means of a lever type handle connected to an operator plate that is both pivotally and slidably mounted in an operator housing. A sector plate connected to the louvers is pivoted in the housing adjacent to the operator plate. To open or close the louvers, the operator handle must first be slid upwardly to unlock the operator plate; then upon rotating the handle, the sector plate is engaged to open the louvers. To close the louvers, the operator plate is permitted to slide downwardly causing the operator plate and sector plate to become engaged and when the handle is rotated in the opposite direction, the louvers are closed and the operator handle arrives at its retracted position to lock the operator plate and sector plate.

This invention relates to window structures and is more particularly directed to a lever type operator for jalousie windows.

A principal object of the present invention is to provide a lever type operator for jalousie windows which automatically locks the louvers or panels in the closed or any of the open positions so that the louvers cannot be forced to a more open position from the outside.

Another object of the present invention is to provide a lever type operator for jalousie windows with a handle which is both rotatably and slidably mounted whereby slidably moving the handle in one direction places the handle in position to operate the jalousie windows and slidable movement in the opposite direction locks the jalousie louvers against pivotal movement.

A further object of the present invention is to provide a lever type operator for jalousie windows which is interchangeable for either left or right side operation, and has a low profile so that it does not interfere with shades, drapes and the like.

A still further object of the present invention is to provide a lever type operator for jalousie windows which is simple in construction, most effective to open and close a jalousie window, and at the same time permit the locking of the window in an open or closed position.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers to my lever type operator for jalousie windows shown mounted on a face member 11 of a frame 12 of an otherwise conventional jalousie window. Extending between side jambs 13 of the frame 12 is a plurality of glass panels 14 whose ends are supported by pivot clips 15. The pivot clips 15 are each pivoted with an arm portion 16 pivotally mounted as by pin 17 to the side jamb 13 while its free end is pivoted by a pivot pin 18 to an operating or slide bar 19 that is slidably mounted along the side jambs 13. One of the operating bars 19 is secured to one end of a link 20 by a pivot pin 21 while the other end of the link 20 is pivoted by a pivot pin 22 to the free end of an arm 23 of a sector plate 24. Along the upper edge portion of the sector plate 24 is a plurality of teeth 29 while on the lower edge portion are a series of dimples 30. A pivot pin 25 rotatably mounts the sector plate 24 within a chamber 26 of an operator housing 27 that is secured to the wall 11 of the frame 12 by screw bolts 28. Also mounted for rotational movement on the pivot pin 25 is a lever operator handle 31 having a plate member 32 whose midportion is provided with an elongated bore 33 to permit the operator handle 31 to slide along the pivot pin 25 as well as pivot thereabout as is explained in greater detail hereinafter. Secured to the plate member 32 is an elongated handle portion 34 off-set from the plate mem ber 32 as is likewise the finger or projection 35 on the top portion of the plate member 32; the finger 35 extending in the direction of the bore 33. The projection or finger 35 of the operator handle 31 is adapted to become selectively engaged with the teeth 29 of the sector plate 24. At the bottom portion of the plate member 32 is a slotted portion or shoulder 36 that is adapted to receive a detent 37 mounted for limited sliding movement on a support member 38 secured to the housing 27 by a bolt 39.

The support member 38 is slotted at the top portion in alignment with the plate member 32 as at 40 and along the full length of one side as at 41 for receiving a coil spring 42 which retains a ball detent 43 in frictional engagement with the dimples 30 on the sector plate 24. The support member 38 is provided with a stop member 44 that is received by a slot 45 formed in the wall of the detent 37. The stop member 44 permits the limited sliding movement of the detent 37 which is yieldingly maintained in its uppermost position by a coil spring 46. In order that the detent 37 may slide into its locked position in the slot 36 as the handle 31 is rotated back to its neutral position, the detent 37 is provided with an inclined top surface 48 that engages the arcuate edge portion of the plate member 32.

When the jalousie window 10 is in its closed and locked position the glass louvers 14 will be closed as shown by FIGS. 1 and 2 and the various parts of the operating mechanism will assume the position as best shown by FIGS. 2 and 3. The operator handle 31 has been pivoted to place the handle portion 34 at its lowest position with its projection 35 engaged with the furthermost tooth 29 of the sector member 24 locking the sector member 24 3 and operator handle 31 together. The sector arm 23 is at its highest position as is the slide bar 19 causing the louvers 14 to have been swung to their closed position, while the detent 37 has slid upwardly to engage the shoulder 36 to lock the operator handle 31 to the housing 27 and prevent any pivotal movement of the operator handle 31. With the operator handle 31 and sector plate 34 locked in position, the link 20 and slide bar 19 are prevented from moving. Consequently anyone trying to pivot the louvers 14 to an open position by applying a force directly on the louvers will find them rigidly locked in position and will resist the attempt to open the louvers.

In order to swing the louvers 14 to an open position, the operator handle must first be slid upwardly to remove the detent 37 from the slot 36 and thereby release the sector plate 24 as shown by FIG. 4. In this position, the louvers 14 are still in a closed position, but the operating mechanism is no longer in a locked position, so that the louvers 14 may be opened upon swinging the handle 34 upward. As shown by FIG. 5, the free end 49 of the operator handle 31 engages a shoulder 50 of the sector arm 23 and causes it to rotate on its pivot pin 25. This causes the arm 23 to swing downwardly carrying the link 20 and the slide bar 19 downwardly with the result of the louvers 14 pivoting to an open position.

It is desired to lock the louvers 14 in their open position, all that need be done while the operator handle 31 is in the uppermost position as shown by FIG. is to pivot the handle 34 about the pivot pin 25 while the pivot pin 25 is in the lower portion of the elongated bore 33 until the slot 36 is aligned with the detent 37. Then a downward force applied on the handle 34 will cause the operator handle 31 to slide downwardly along the elongated bore 33 to position the pivot pin 25 in the upper portion of the elongated bore 33, the projection or finger 35 will engage one of the teeth 29 while the coil spring 46 will urge the detent 37 to slide into the slot and engage the shoulder 36, thereby locking the louvers 14 in their open position. As long as the detent 37 is in engagement with the shoulder 36 and the finger or projection 35 received by a tooth 29, the louvers 14 cannot be opened if closed or swung to a more open position, it in an open position.

To return the open louvers 14, as shown by FIG. 6, to their closed and locked position, as shown by FIGS. 2 and 3, the handle 34 is grasped and forced to slide upwardly to release the detent 37 from the shoulder 36, the finger 35 rises above the teeth 29 and the pivot pin 25 becoming positioned at the lower portion of the elongated bore 33 as illustrated by FIG. 4. The handle 34 is pivoted about the pivot pin 25 until the free end 49 engages the shoulder 50 as best shown by FIG. 5. Now, the operator handle 31 is slid downwardly to compel the pivot pin 25 to be positioned at the upper portion of the elongated 'bore 33 and the finger 35 will be received by the tooth 29 adjacent the shoulder 50 as best shown by FIG. 7. The detent 37 will have slid downwardly against the spring pressure 46 as the arcuate edge portion of the sector plate 32 will have engaged the inclined surface 48 of the detent 37. Upon forcing the handle 34 to swing toward the wall 11 of the frame 12, the sector gear 24 will rotate about the pivot pin 25 and swing the arm 23, link 20 and slide bar 19 upwardly to close the louvers 14. When the louvers 14 have arrived at their closed posi- 4 tion the detent 37 will be received by the slotted portion 36 to lock the operator handle 31, as shown by FIG. 3. Since the finger or projection 35 has engaged the tooth 29, the sector gear 24 will likewise be locked against rotational movement while the louvers 14 will be in their closed and locked position.

The function of the ball detent 43 and peripheral grooves or dimples 30 is to compel the sector gear plate 24 to stop at those positions in which the teeth 29 and finger or projection 35 are in alignment so as they may become engaged upon releasing the handle 34.
