DESCRIPTION OF THE PREFERRED EMBODIMENT
Figures 1-2 show the handle and housing assembly 10 (hereinafter referred to simply as "handle assembly") of 15 the present invention in altEarnative positions and engaged with an operator 12 for opening and closing a window. The window operator 12 has a drive input member 14 engaged with a worm gear drive 16 on a window frame-mountable operator base 17.
20 The gear drive 16 i;s intermeshed with a plurality of pivotally interconnected links 20. The links 2o can be attached to a window sash such that rotation of the drive input member 14 is effective. to pivot the interconnected links 20 and open and close a window in a suitable manner.
25 Though one type of operator si:ructure is shown for purposes of illustration in Figs. 1-2, it should be understood that the present invention could be: readily adapted for use with virtually any type of window operator.
Specifically, the handle assembly 10 includes a 30 cover or housing 22 secured to the window operator 12 as described in greater detail hs:reafter. A handle base 24 is drivingly engaged with the drive input member 14. An elon 2087309 _. 6 gate handle 26 is connected at an end 28 thereof to the handle base 24 to allow manu~~l rotation of the drive input member 14. A hinge pin 30 couples the handle end 28 with the handle base 24 so that the handle 26 is movable rela-y tive to the handle base 24 :between an extended operating position (Fig. 2) in which the handle 26 is operable to rotate the drive input member 14 and a folded storage posi-tion (Fig. 1) in which the handle 26 overlies the handle base 24. A knob 32 is mounted in pivotal relation on an opposite end 34 of the handle 26 so that the knob 32 can be rotated relative to the handle 26 to facilitate operation in which the handle 26 is pivoted about the base 24 to apply torque to the drive in~~ut member 14.
An important object. of the present invention is the manner in which the abov~a described components of the handle assembly l0 are interconnected as described in de tail below.
The handle base 24 and the drive input member 14 have complementary interengaged splines 33 for transmitting torque between the handle 26 and the drive input member 14.
A pair of set screws 35 are spaced approximately ninety degrees from each other and e:Ktend through the handle base 24 and engage the drive inpui~ member 14. The use of two set screws prevents the handle base 24 from rocking rela tive to the cover 22.
As shown in Figures 3 - 5, the end 34 of the handle 26 has a generally cylindrical opening 36. The knob 32 has a generally cylindrical opening 38 substantially aligned with the opening 36 in the handle 26. An axial pin 40 has a headed end 42 received in the opening 36 and a shank 44 received in the opening 38 to maintain alignment of the handle 26 with the knob 32. The pin 40 extends through a sleeve 46 positioned in the opening 36. The -_ zo 8~3og ~~_ sleeve 46 preferably is stainless steel and has a knurled exterior surface 48 in frictional press fit engagement with the inner wall of the opening 36 whereby the sleeve 46 acts as a bearing and permits rotation of the pin 40 about its axis relative to the handle :>.6. The shank 44 of the axial pin 40 has an integral knurled surface 50 in frictional press fit engagement with thE: inner wall of the opening 38 to fix the pin 40 to the knob 32.
The above construction of the handle 26 and the knob 32 (i.e., the press fit interconnection of the handle and the knob) provides a structure which is easily assem bled and readily serviceable. In addition, it should be recognized that the advantages of this aspect of the pres ent invention can alternatively be achieved by positioning the headed end 42 of the axial pin 40 and the sleeve 46 in the opening 38 on the knob 32 and by positioning the knurled shank 44 of the pin 40 in the opening 36 on the handle 26.
Structure for re leasably securing the cover 22 to the window operator 12 is shown in Figures 6 - 9.
Specifically, the cover 22 has a circulax opening 52 through which the spline 3:3 on the drive input member 14 extends. A countersunk groove 54 extends around the pe-ripheral edge of the opening ..°i2 and a pair of diametrically opposed slots 55a and 55b extend radially from the opening 52. A tubular boss 56 on the operator base 17 supports the drive input member 14 and has a pair of locking grooves 58 and 59. A retainer clip 60 releasably secures the cover 22 to the tubular boss 56 in the manner described herebelow.
The retainer clip 60 preferably is made of plas-tic and has a neck 62 which extends axially thrpugh the opening 52 on the cover 22. The drive input member 14 extends coaxially through the neck 62 and the opening 52 in _g_ the cover 22 and engages the handle base 24. A pair of undercut tabs 61 on the inside of the retainer clip 60 snap into a corresponding one of the locking grooves 58 and 59 on the boss 56 to releasably secure the retainer clip 60 to the operator base 17.
A pair of diametrically opposed resilient tabs 64 are struck from the retainer clip neck 62. Each tab 64 has an undercut end 66 for snappingly engaging the groove 54 when the neck 62 is inserted into the cover opening 52 (see Figure 8). A pair of radial tabs 66a and 66b on the neck 62 engage the slots 55a and !55b, respectively, and prevent the cover 22 from rotating relative to the boss 56.
In a preferred embodiment of the present inven tion, the clip tabs 61 will be such that the clip 60 will release the boss 56 before the clip tabs 64 release the cover 22. However, as an alternative embodiment, the cover 22 may be configured with an inner surface enclosing the clip 60 at the tabs 61 when assembled. In this manner, the clip 60 may first be assembled onto the boss 56 with the clip 60 flexing slightly outwardly to allow the tabs 61 to snap into position. Then, when the cover is mounted over the clip 60 (as described below), the cover 22 will prevent the clip 60 from thereafter :flexing outwardly and thereby prevent the clip tabs 61 from undesirably disengaging from the locking grooves 58, 59 while assembled.
Of course, it is also desirable to match the cover 22 and the operator bass: 17 in such a manner that the outer perimeter of the cover 22 is secured to the base 17 by the above described assembJ.y in such a manner that cover 22 is secured against twisting relative to the base 17.
Further, the retainer clip neck 62 is preferably matched to the input member 14 by an interference fit and is attached to the handle base. 24 as previously described.
zo s~3o9 ..-9-As a result of this arrangs:ment, location tolerances be-tween the cover 22 and the handle base 24 are kept to a minimum. This is particular:Ly desirable with handle struc-tures like that shown where aesthetics and function require that the handle properly nest in the cover 22 when closed.
Referring next to Figure 10, and also with refer ence to Figures 1 and 2, the: cover 22 has a pair of oppo sitely sloped sidewalls 68 and 70 and a recess 72 inter posed between the sidewalls 68 and 70 for receiving the l0 handle 26 when the handle 26 is in the folded position.
The handle 26 has a pair of spaced apart side-walls 74 which define a cavity 76 on the underside of the handle 26 for concealing the handle base 24 from view when the handle 26 overlies the cover 22 in the folded position.
In addition, one end 34 of the handle 26 is angled with respect to the other handle End 28 so that the knob 32 and the handle end 34 overlie and conform to the sloped side-wall 70 when the end 28 of the handle 26 is received in the recess 72.
In order to properly align the handle 26 with the recess 72 when the handle 26 is moved to the folded posi-tion, a locator member or block 78 is positioned in the cavity 76 and is attached to the underside of the handle 26. The locator block 78 has a pair of spaced apart open-ings 80 suitably secured to corresponding alignment pegs 82 on the handle 26 (by, for ex<;mple, an adhesive bonding or a friction fit) to maintain a preferred position of the locator block 78 on the handle 26. The recess 72 on the cover 22 has a notched end wall 84 which is adapted for positive engagement with a complementary surface 86 on the locator member 78. Engagement between the locator member 78 and the notched wall 84 ho:Lds the folded handle 26 in a centered position on the cover 22 and prevents the folded -- zo 8~3os ~1°-handle from being shifted laterally and rotating the drive input member 14.
Further, the handy: 26 could be secured in either its extended or folded position, if desired, by suitable means such frictional engagement, detent structures or the like.
As will be understood by those who have gained an understanding of the present invention from the disclosure herein, the above described handle assembly l0 provides efficient and reliable operas=ion over the long life of the window with which it is used. This handle assembly 10 conveniently folds into an aesthetically pleasing configu-ration wherein the handle 2E. conceals the handle base 24 from view and the knob 32 Overlies and conforms to the shape of the cover 22. Moreover, the compact arrangement of the folded handle assembly reduces the likelihood that an exposed handle member will be scratched, bent, or other-wise damaged. The simple yet. reliable connections between the handle assembly components facilitates assembly and maintenance throughout the serviceable life of the inven-tion. The simplicity of this invention contributes to ease and low cost of manufacture.
Still other aspects, objects, and advantages of the present invention can be obtained from a study of the specification, the drawings, and the appended claims.

Referring next to Figure 10, and also with refer ence to Figures 1 and 2, the: cover 22 has a pair of oppo sitely sloped sidewalls 68 and 70 and a recess 72 inter posed between the sidewalls 68 and 70 for receiving the l0 handle 26 when the handle 26 is in the folded position.
The handle 26 has a pair of spaced apart side-walls 74 which define a cavity 76 on the underside of the handle 26 for concealing the handle base 24 from view when the handle 26 overlies the cover 22 in the folded position.
In addition, one end 34 of the handle 26 is angled with respect to the other handle End 28 so that the knob 32 and the handle end 34 overlie and conform to the sloped side-wall 70 when the end 28 of the handle 26 is received in the recess 72.
In order to properly align the handle 26 with the recess 72 when the handle 26 is moved to the folded posi-tion, a locator member or block 78 is positioned in the cavity 76 and is attached to the underside of the handle 26. The locator block 78 has a pair of spaced apart open-ings 80 suitably secured to corresponding alignment pegs 82 on the handle 26 (by, for ex<;mple, an adhesive bonding or a friction fit) to maintain a preferred position of the locator block 78 on the handle 26. The recess 72 on the cover 22 has a notched end wall 84 which is adapted for positive engagement with a complementary surface 86 on the locator member 78. Engagement between the locator member 78 and the notched wall 84 ho:Lds the folded handle 26 in a centered position on the cover 22 and prevents the folded -- zo 8~3os ~1°-handle from being shifted laterally and rotating the drive input member 14.
Further, the handy: 26 could be secured in either its extended or folded position, if desired, by suitable means such frictional engagement, detent structures or the like.
As will be understood by those who have gained an understanding of the present invention from the disclosure herein, the above described handle assembly l0 provides efficient and reliable operas=ion over the long life of the window with which it is used. This handle assembly 10 conveniently folds into an aesthetically pleasing configu-ration wherein the handle 2E. conceals the handle base 24 from view and the knob 32 Overlies and conforms to the shape of the cover 22. Moreover, the compact arrangement of the folded handle assembly reduces the likelihood that an exposed handle member will be scratched, bent, or other-wise damaged. The simple yet. reliable connections between the handle assembly components facilitates assembly and maintenance throughout the serviceable life of the inven-tion. The simplicity of this invention contributes to ease and low cost of manufacture.
Still other aspects, objects, and advantages of the present invention can be obtained from a study of the specification, the drawings, and the appended claims.
