7 Claims.

This invention relates to new and useful improvements in operating handles and more particularly to handle assemblies for operatingand locking jalousiesand Venetian windows in adjusted positions.

v One object of the invention is to provide an improved handle for operating ajalousie and Venetian window and of such construction that the handle may be locked readily in any desired gfoisigion toprevent operation of the jalousie or Another obiect of the invention is to provide an improved handle assembly for operating and locking jalousies and Venetian windows in adjusted positions which includes a pivoted rotatable lever and cam means rotatable with and actuated by pivotal movement of the lever for moving conical surfaces into engagement so as to lock said lever against rotation, together with nmegns for connecting said lever to an operating A particular object of the invention is to provide an im roved handle assembly, of the character described, which includes an angular member journaled in and extending through a support for connecting the lever to an operating link whereby the member is rotated by said lever so as to reciprocate the link and functions as a bearing for said lever.

A further object of the invention is to provide an improved handle assembly, of the character described, wherein the angular member has a shoulder overlying the inner surface of the support and disposed in the bore of a base plate secured to said inner surface whereby said member is confined therebetween and isinsertable inwardly of said support, the lever being connected to said member by an element rotatably and'slidably mounted in said bore. ,7

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the specification and byreference to the accompanying drawing, wherein an example of the invention is shown, and wherein:

Fig. 1 is an exploded, perspective view of a handle assembly constructed in accordance with the invention, I

Fig. 2 is an enlarged, transverse; vertical, sectional view of the handle assembly, shown In the drawing, the numeral lfl designates a handle assembly for operating or tilting or locking the louvers of a jalousie or Venetian window (not shown) in open, closed or intermediate positions. The assembly I includes an angular arm or member H, a connecting element or spindle mounted on a frame member and in its unlocked position, and Fig. 3 is a view, similar to'Fig. 2, showing the locked position of the assembly.

' spindle.

l2, a base or an escutcheon plate l3, a cam member or ring l4 and an actuating lever 15 which is adapted to be pivotally connected to the spindle by a transverse pin l6. As shown in Figs. 2 and 3, the plate 13 is substantially fiat and rectangular and is adapted to be secured in overlying relation to the inner surface of a support or frame member H, which is angular in crosssection, by suitable screws l8 and nuts [9. An operating link is pivotally connected by a rivet 2! or other suitable means to the lateral portion or leg 22 of the arm II.

It is noted that the spindle [2, plate l3, cam ring I4 and lever I5 are shown in the co-pending application of Sanderlin and Grant filed July 18, 1949, Serial No. 105,384. A transversely-extending boss 23 is formed on the plate and has a cylindrical opening or bore 24 for receiving the The major portion of the bore 24 is tapered or flared outwardly toward the inner side of the plate so as to provide a conical counterbore or wedge surface 25. 'An-annular recess 26 is provided at the extremity of the conical counterbore adjacent'the inner side of the plate. The spindle l2, while generally cylindrical, has flat sides 28 and is of a length considerably greater than the length of the bore 24, its counterbore, and recess, so as to project beyond the boss 23 when engaged in said bore. A conical enlargement or wedgesurface 21, complementary to theconical counterbore, is formed on the inner end portion of the spindle for coacting with said counterbore to lock or grip said spindle against rotation. Intermediate the conical and flattened surfaces 21' and 28, a circular portion 29 is provided for coacting with the cylindrical bore 24 in maintaining the spindle in axial alinernent with said bore. It is preferable to round or bevel the outer end of the spindle as shown by the numeral 30. A polygonal socket 3] is formed in the inner end of the spindle (Fig. 3) V The lever includes a curved handleportion 32 and anenlarged head 33 having a deep, rectangular recess or socket 34 complementary. to the outer end portionlof the spindle, said spindle portion being confined in the socketby the connecting pin l6. Limited pivotal movement of the lever about the axis of the pin and relative to the spindle is permitted by a slot 35 cut in the wall of the head 33 opposite the handle portion 32. A pair of inwardly-directed, parallel ears or extensions 36 are formed by the provision of the recess and the slot and the inner ends of these ears are curved or bevelled outwardly and longitudinally to provide cams or cam faces 31 for coacting with the cam ring 14.

Ihe cam ring is preferably circular externally and has an elongate opening or slot 38 through which the flattened portion 28 of the spindle extends, whereby said ring is rotatable with said spindle; the slot being generally complementary to the cross-sectional shape of the spindle. It is noted that the slot 38 is of a length greater than the largest diameter of the spindle portion 28 so that the ring may slide or move transversely relative to the lever and spindle. Arcuate, undercut cams or cam faces 39 are formed in the outer end surface of the ring parallel to the longitudinal axis of its slot for coacting with the cam faces 31 to draw the

oonicalwedge surfaces

25 and 21 into tight engagement. By ofI- setting the slot longitudinally toward the inner or head end of the lever, the. low points of the cam faces 39 move past the high points of the cam faces 31 upon inward swinging of the lever so as to increase the locking action of said-faces (Fig. 3). Outward swinging of the lever moves the cam faces into registration so as to disengage the conical wedge surfaces (Fig. 2).

The arm ll includes a substantially cylindrical body portion 40 carrying the lateral portion or leg 22 and having an enlarged annular bearing. 4| which is adaptedto be journaled in an opening 42 formed in the support H. An enlargement in the form of a radial shoulder. or flange 43 is formed externally of the bearing t! for engaging the inner 'surfaceof' the support in overlying relation to the opening 42. The enlargement 3-3 is disposed within the recesslt of the plate 13 so as to be confined betweenv said plate and the support. A polygonal stud or shank M is formed onthe inner extremity, of the body G for slidable engagement with the socket 3|.

In operation, thelever is swung outwardly to unlock the spindle and permit rotation thereof by turning of said lever. The camfaces. 3'! and 53' are moved into registration by outward swinging of the lever andthe cam ring M is slid toward the outer end of said lever (Fig. 2). Ihi permits inward movement of the spindle and disengagement of the conical. surfaces 25 and 2?, whereby thelever, spindle and angular arm may be freely rotated to swing the leg 22 of said arm and reciprocate the linkv 20.. Whenever it is desired tolocklthe. linkin an adjusted position, which may be-closed', open or intermediate positions, the lever is swung inwardly (Fig. 3). It is noted that the. ring 14' has a transverse sliding movement and that the arcs, on which the

camfaces

31 and 39 are struck, do not have their centers in the bolt. pin. IS on which the lever 15 swings. In the locked position, the handle is swung inwardly and the ring I4 is moved upwardly (Fig. 3); thus,.fastening the parts against rotation; but when the handle is swung outwardly, the cam ring is moved downwardly (Fig. 2). thereby'freeingthe parts for rotation. Due to the registration of the cam faces, the camring. slides toward the inner end of the lever and into axial alinement with the spindle- Upon continued inwardswinging of the lever, the cam faces31 ri'd'e" slightly past registrationwith the cam faces soa s to force the spindle outwardly and tightly engage the coni- 4 cal surfaces of the bore and spindle. In this manner, the spindle is locked against rotation so as to maintain the link in the desired position.

It is noted that the length of the conical surface 25 is greater than the length of the conical surface 21 of the spindle so as to permit movement of the spindle relative to the arm. As shown in Fig. 3,.the socket 3| and shank 44 provide a slidable connection between the arm and spindle so as to permit relative longitudinal movement of said spindle. The bearing 4| serves to support the spindle for maintaining the same in axial alinement with the bore 24. Due to the provision of the shoulder 43, the arm H is confined by the coaction of the base plate l3 and the support I! and is insertable inwardly of said support. Y

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated. construction may be made, within the scope of theappended claims, without departing from the spirit of the invention.
