12 Claims.

This invention relates to a mechanical operator and particularly to a jalousie operator.

A main object of the present invention is to provide a mechanical operator which can be used to adjust a wide range of devices such as valves, dampers, pushing devices for turn tables or platforms, etc., and in fact any device where load reactions on the controlled device might disturb the adjustment and wherever the use of a single force to both unlock and actuate the operator would be necessary or convenient. Although the invention will be described in connection with a jalousie operator, the invention is not intended to be limited by this description unless specifically set out in the claims.

A principal object of the present invention is to provide an improved jalousie operator, and particularly to provide a self-locking jalousie operator, operable to automatically unlock to perrnit operation thereof and therefore adjustment of the slats of a jalousie, and to automatically resume a locking condition after adjustment of the slats to thereby retain the slats in adjusted position.

Another object of the present invention is to provide a self-locking jalousie operator as above described which is simple and inexpensive in construction, reliable in operation, compact, and readily applied to'a window frame.

Various other objects of the present invention will be apparent from the following description taken in connection with the accompanying drawings in which:

Fig. 1 is a fragmentary cross-sectional view in side elevation through a window of the jalousie type having ajalousie operator of the present invention incorporated therein.

Fig. 2 is a fragmentary cross-sectional view in side elevation taken through the jalousie operator disclosed in Fig. 1 and showing the parts of the jalousie operator in the positions they occupy when the operator is locked and when the slats are in closed position.

Fig. 3 is a horizontal cross-sectional view taken along line 33 of Fig. 2 in the direction of the arrows.

Fig. 4 is a vertical cross section taken along line 44 of Fig. 2 in the direction of the arrows.

Figs. 5 and 6 show diagrammatically the positions occupied by certain of the parts in the jalousie operator when the operator is being operated for movement in opposite directions.

Referring to the accompanying drawings, wherein similar reference characters designate similar parts throughout, Fig. 1 shows a jalousie operator generally indicated as 9 being mounted on a jamb ll) of a window frame generally entitled l l and connected by a link it to a travel bar i5. Travel bar is is connected by levers I? to a plurality of slats is which are adapted to be adjusted in various angular positions through operation of the jalousie operator 9. Slats 19 are pivotally connected at 2! to the jambs of window frame i l, the general construction of such a jalousie window not being a particular part of the present invention and therefore only described generally.

Jalousie operator 9 includes a case 22 containing a part of the operating mechanism of the jalousie operator. Case 22 assumes the form of an open box casting recessed in jamb l0 and held in place by a mounting plate 23, secured to the case by screws 23a and to the jamb by screws 23b. There is an escutche'on plate 24 secured to the righthand wallof case 22 by screws 24a and to the jamb ill by screws 24b. The operating mechanism 01- the jalousie operator 9 includes a first class composite lever 25 which is pivotal about a pivot pin 21, and at its inner or lefthand end, as the parts are depicted in Fig. 2, is operatively connected to a lever-actuated vertically movable traveling yoke 29 by a pivot pin 3! and a roller 32 carried thereon and disposed within the groove of a horizontally grooved guide block 33 which is secured to travelingyoke 29 by rivets 3 Guide block 33 permits lateral movement of the arcuately movable pivot pin 3! and roller 32 relative to the linearly movable traveling yoke 29' upon operation of lever 25. Traveling yoke 29 is connected by a pivot pin 35 to previously mentioned link l3 whereby slats l9 can be opened, closed or adjusted to any intermediate position by operation of lever 2 5.

Mounting plate 23 has an oblong slot 35 therein through which pivot pin 35 extends and within which pivot pin 35 travels. Jamb it is suitably recessed to accommodate the movement of yoke 29. Escutcheon plate 24 and the wall of case 22 to which it is attached have registered oblong openings formed therein to accommodate the movement of lever '2 5.

To hold slats l9 in any desired position of adjustment, a releasable locking mechanism is provided. This locking mechanism includes a looking rod 31 secured at its ends by screws 38 to end flanges 38a on yoke 29 and slidably receivable through the upper and lower walls of a case 22 and through a pair of latching plates 40. Latching plates 40 are pivotally mounted at their lefthand ends, as the parts are depicted in Fig, 2, in

U notches 40a formed on case 22, and urged apart by a compression spring 4| secured to the plates by rivets 4 a.

Latching plates 40 have the apertures thereof, receiving locking rod 31, of a size to loosely receive the locking rod so that the latching plates, under the influence of compression spring 4|, assume positions angularly transecting the locking rod. Since such latching plates are, per se,

old in the art apart from the present combination, it is apparent to those skilled in the art that the upper latching plate will prevent upward movement of locking rod 31 and the lower latching plate will prevent downward movement of locking rod 31.

For automatically effecting a release of latching plates 45, a release member 43 is provided and pivotally mounted at its lefthand end to case 22 by a pivot pin 47 and operatively connected by the previously mentioned pivot pin 21 to composite lever 25. It is apparent that pivot pin 3| will be held stationary and therefore lever will be held relatively stationary, by the engagement of latching plates with looking rod 37 until a release of the appropriate plate is effected, and, therefore, during the first increment of movement of lever 25 in either of its directions of movement, lever 25 functions as a second class lever, pivoting about pivot pin 3| and swinging release member 43 through the medium of pivot pin 21 in the same direction of movement as the handle end of lever 25.

However, only limited movement of release member 43 is permitted, said release member at its righthand end engaging a stop 49 when lever 25 is pivoted clockwise, and engaging a stop 56 when lever 25 is pivoted counterclockwise, said stops being formed on case 22 (see Figs. 5 and 6). After engagement with either

stop

49 or 50, release member is stationarily held and lever 25 thereafter operates as a first class lever to urge traveling yoke 29 in the opposite direction from which force is applied to the handle end of the lever. In order to release the yoke for movement, release member 43 has a pair of latch-engaging screws 5| threadedly received by offset ears 52 formed on release member 43. One of the screws 5| is adapted, when the release member is moved in one direction, to engage the adjacent latching plate, and the other of which is adapted to engage the other latching plate when the release member is moved in the opposite direction. (Compare Figs. 5 and 6). Such engagement moves the latching plates, individually and separately, from their normal latching positions to positions where their bores are more nearly aligned with looking rod 31, and holds the latching plates, individually and separately, against pivotal movement in the direction urged by locking rod 31, thereby permitting the locking rod to slide through the latching plates and therefore permitting adjustment of slats l9 by operation of lever 25. Release member 43 is moved to a non-releasing position, after lever 25 is released, by a leaf spring secured at one end to case 22 and at its opposite end to release member 43. Release member 43, during such movement, carries lever 25 therewith, the operative connection of pivot pin 3| and roller 32 in guide block 33 permitting such movement of lever 25.

Screws 5|, by virtue of their threaded engagement with cars 52, are adjustable toward and away from their respective latching plates, and adjusted so that when release member 43 is in 2 its non-releasing position, the inner opposed ends of the screws are disposed closely adjacent to but spaced from their respective latching plates. Screws 5| are held in their adjusted positions by compression springs 51. Screws 5| have hex heads to facilitate easy adjustment of the screws.

Composite lever 25 includes a tapered socket portion SI and a removably tapered handle portion 63 fitting in the socket portion. The handle portion is preferably removed after adjustment to avoid possible injury to a person passing the window.

Although the operator is shown as being directly manually operated, it is apparent that the device could be remotely controlled such as by rope, chain or push rod arrangement.

By the present invention, a jalousie operator has been provided which is self-locking so that while it may be readily operated to adjust the slats of a jalousie window construction to any desired position, the jalousie operator is operable to prevent movement of the slats initiated by a force imposed directly on the slats or in any other manner except by a force imposed on the lever.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
