Rees and-Douglas Cloutier, Chicago, Ill., assignors to Illinois Tool Works, Chicago, Ill., a corporation of Illinois Application February 3, 19,49, Serial No. 74,338 12 Claims. (Cl. 189-46) The present invention relates in general to improvements in detachable handle constructions for panels and the like.

More particularly the invention relates to improved fasteners and fastener arrangements for detachably securing a handle to a panel in which a fastening stud must pass through an aperture in the handle and extend into interlocking association with the wall of a panel.

One of the objects of the present invent-ion is to provide a handle fastener arrangement of the above mentioned type in which the fastener stud when used with a panels comprising spaced `sections or` walls need not cornpletely penetrate both panel sections.

Another objectof the present invention` is to provide a fastener` of the type described for panels composed of two spaced panel or Wall sections in which a resilient locking dev1ce cooperates with a stud member to hold the panel sections together.

Heretofore it has not ybeen uncommon to thicken the area of a -sheet metal panel section in the vicinity where a handle is to be applied in order to lend suflicient strength, and it is an object of the present invention to provide a h andle fastener arrangement which eliminates the necessity of providing a `thickened panel section and hence materially reduces constructional costs.

ln securing `handles to enameled surfaces, such as oven doors and the like by conventional fasteners enamel cracks frequently result and it is an object of the present inven` tion to provide a handle fastenery arrangement which will reduce to a minimum -any tendency to crack enamel on the panel to which the handle is secured.

Still another object of the invention is to provide a handle fastener arrangement which will resiliently secure or clamp the panel sections together and fasten the handle on the panel in such a manner as substantially to eliminate rattle and vibration noises `in the panel.

Still another object of the invention is to provide a clip which is adapted to :be snappedinto positionto hold together the panel sections of a panel and which is adapted to receive and interlock with a fastener shank for `securing a handle to the panel.

These and other obiects of the invention will best be understood upon consideration of the following specificatio'n and the accompanying drawings wherein:

Referring now to the drawings more in detail wherein like numerals have been employed to designate similar parts throughout the various views it will be seen that Fig'- ure 1 shows a handle 20 fastened to a panel 22 in the manner contemplated by the present invention. As best seen in Figure 2 the panel 22 consists of a front panel section 24 and a back panel section 26 which have laterally extending ange portions 28 and 30 respectively. Between these panel sections 24 and 26 and substantially lling the space therebetween is a body of insulation mat,- ting 32.

The handle 20 is composed of two sections, an upper section 3,4 `and a lower section 36. Upper section 34 has a flange portion 38which is bent `at a relatively acute angle with respect to the main body of the `handle section 34 and which is normally positioned adjacent the front panel section 24. There is positioned on this ilange portion 3.8 a re-entrantly bent section 40 (see Figure 4.) which is positioned at the center thereof and which is adapted to engage an edge of the lower handle section 3 6. The edge of the upper handle section 34 on which is formed the flange portion 38 is recessed at points 42 and 44 to form a ventilating space between the center of the handle 20 and the panel 22. On `the `other edge of the upper handle section 34 is formed a second flange portion 46 which receives .one edge of the lower handle portion 36.

The lower handle portion 36 has a laterally extending portion 48 which engages the flange 46 on the lower edge of upper` portion 34. The center `of the lower handle por-` tion 36 is curved smoothly upwardly to form a handle grip portion 50 and the` upper edge of this handle `grip portion 50 engages the re-.entrantly bent flange 4,0 of the upper handle section 34. On either side of this handle grip portion 50 are two fastener receiving portions 52 and 54 in which are positioned apertures 56 and 58 respectively. The general ,shape and arrangement of the handle is best understood by referring to drawings 2, 3, 4, 6 and 7.

The front and back panel sections 24 and 26 `are held together at their upper end by a resilient locking member or clip 6i). This clip 60 passes through openings in the flange members 28 land 3 0 of the front and back panel sections 24 and 26 and is held in position in a manner which will be described later. A stud 62 passes through .each of the openings 56 and 58 in the lower handle member 36 through an opening 64 in `the front panel section 24 and engages the clip 60. The clip 60 (see Figure` 5) is made of any suitable material such as sheet metal and is formed by first cutting or stamping the clip in the proper shape and then bending to the form shown in Figure 5,

The clip 6i) consists `of a head portion 66 on which 4are formed shoulders 68. From one `side of' head 66 is a depending strip 70 upon which is struck or formed a tongue '72. Opposite the depending strip 70 is a shank portion 74 which has formed thereon an extruded thread or helix 76. On the lower edge of shank portion 74 is a laterally bent brace 78 which is substantially parallel .to the head 66.

As shown in Figure 2, the clip is positioned through openings in the flanges 20 and 30 and after insertion therein the tongue 72 engages the flange 30 and the brace '78 bears against the inner side of the front panel section 24. The shoulder 68 on head 66 prevents the clip 60 from dropping through the openings in the flanges 28 and 30. The portion of the shank 74 in which is p0- sitioned the extruded thread 76 is bent slightly so that this portion of shank 74 is substantially parallel to the plane of the fastener receiving portions 52 and 54. Upon insertion of stud 62, which in this embodiment of the invention is a screw, through apertures 56 and 64, the threaded portion of stud 62 engages the extruded thread 76 on the clip 60. When the stud 62 is screwed tightly into place, the clip 60 will resiliently hold the handle 20 against the front panel section 24 and will also resiliently hold the front and back panel sections 24 and 26 together. This particular construction and method of securing the handle 20 to the panel 22 minimizes the vibration noises and rattling, and also securely holds together the free margin of the front and back panel sections 24 and 26.

Figures 8-10 show another embodiment of the invention in which a quick operating fastener 82 is substituted for the screw 62. The quick operating fastener 82 has a shank portion 84 on which are formed two lugs 86 at one end thereof; the other end of shank portion 84 .has formed thereon a head 88. The shank portion 90 of the clip 92, which corresponds to clip 60 described above, has formed therein an embossed cam portion 94 instead of an extruded thread as is shown in the embodiment of Figure 5. The remainder of the construction of the clip 92 is identical with that of clip 60. The retaining washer 96 is an additional feature of this embodiment of the invention. This retaining washer 96 has a Hat washerlike portion 98 from which extend resilient fingers 100. In the center is an aperture 102 which is large enough to receive the shank 84 of the quick fastener 82.

The purpose of the retainer washer 96 is to keep the quick fastener 82 attached to the handle 20 during the period immediately preceding assembly and whenever the handle is removed from the panel. This is accomplished by inserting the quick fastener 82 through the aperture 58 in the handle 20 and slipping the retaining Washer 96 over the lugs 86 on the quick fastener 82 and positioning it upon the shank 84 until it engages the handle 20. The tension in resilient fingers 100 will keep the washer in place.

Figures 1l-13 show another type of clip which is adapted tobe inserted through the front of the front panel section 24 instead of through the ange on the front panel section 24. The use of this clip 110 necessitates a slight modification in the back panel section 112. The flange 114 at the top of this back panel section 112 is extended until it reaches the rear side of the front panel section 24 and is then bent downwardly to form a clip engaging portion 116. This clip engaging portion 116 may be a flange formed on the end of flange 114 or might be a lug sheared down from the top edge of back panel 112.

Clip 110 is made of any suitable material such as sheet metal. It is formed by stamping a blank 118 such as the one shown in Figure 13 from a strip of sheet metal and then bending this blank 118 into the shape shown in Figure l2. The finished clip has a head portion 120 from which is struck or formed a tongue 122. Depending from two edge's of the head 120 are two flanges 124 which extend beyond the edge of the head 120 and terminate there in ears 126. On the edge opposite that on which is formed the ears is the shank portion 128. In the particular embodiment shown, a thread or helix 130 is extruded from the shank portion and at the lower end of the shank portion is formed a laterally extending brace 132.

This clip is inserted through an aperture in the front panel section 24, and when in position, the tongue 122 engages in clip engaging portion 116 of back panel section 112, and the brace 132 presses against the rear side of front panel section 24. The ears 126 prevent the clip from passing completely through the aperture in front panel section 24. A screw 62 passes through the aperture in the handle and the front panel section 24 and engages the extruded thread 130 of clip 110 in the same manner as the embodiment shown in Figure 2.

Figures 14-16 show another embodiment of the invention in which the clip is adapted to be inserted through the front panel section 24. With this form of the invention it is also necessary to form a clip engaging portion 116 on the back panel member 112. The manner of forming the clip 140 is the same as that described above, and Figure 16 shows the blank 142 for the clip 140 before bending.

The clip has a head section 144 on which is formed Y the tongue 146. On the edge of the head 144 opposite the base of tongue 146 is a vertically extending ange 148. The shank 150 is connected to the head 144 on the side opposite that on which is formed ange 148. The shank 150 has formed thereon an extruded thread or helix 152 and at the lower edge of the shank 150 is a laterally extending flange 154. When the clip 140 is inserted through the hole in the front panel section 24, tongue 146 engages the depending flange 116 of the rear panel section 112 while the laterally extending flange 154 engages the inner side of front panel section 24. When the handle 20 is snapped into position, the vertically extending flange 148 of the clip 140 engages the flange portion 38 of handle 20. A screw 62 passes through the aperture in the handle and the front panel 24 and engages the extruded thread 152 of clip 140. Upon tightening screw 62 the handle 20, front panel section 24 and the rear panel section 112 will be resiliently held together by the action of clip 140.

The clip in all of the embodiments shown resiliently holds the upper end of the panel sections together before the fastening stud is engaged thereby. This feature is particularly important during the sub-assembly period before the handle is attached to the door panel.
