*3 Claims.
This invention relates to clips and more particularly to a type useful in nonpiercing earrings.
It is the object of the present invention to provide a clip construction for earrings which is rugged and economical and which may be worn with comfort and with certainty of retention over long periods of time.
It is a further object of the present invention to adapt conventional button backs for the reception thereby of a resilient metallic wire clip to attain a resilient clip assembly which may be worn with comfort upon the ear lobes. The invention comprehends the combination of all types of ornamental surfaces with metallic button backs in accordance with the present invention, so that earrings of all type may be had by different combinations of ornamental fronts with the metallic backs such as ornamental button shells of metal, plastics, fabric or cabochons of all types.
This invention presents an improvement over the clip type earring described and claimed in my Patent No. 2,377,688, June 5, 1945.
In my earlier patent, an economical clip type earring was disclosed by stamping a channel in a metallic back to form camming edges at the ends of the channel which protrudes from the external surface of the backing element and into which are inserted inwardly disposed trunnions of a bifurcated spring clip. The arms of the clip, having a common junction at the ends thereof opposite the trunnions, exhibit a tendency to spring back to their original position following a spreading of the arms. Normally the junction end of the spring clip is in contact with the external surface of the backing element. A pivotal movement of the spring clip, at the axis of the trunnions engaging the channel at the camming edges, results in a spreading of the arms of the spring clip by the movement of the arms adjacent to the trunnions towards the wider portion of the camming edges so that this spreading, acting against the resilient force of the spring wire material, gives rise to a force to return the spring clip to its normal position adjacent to the surface of the backing element.
The present invention seeks to improve the construction generally described above and disclosed in the patent in several respects. In the first place, the stamping of the channel outwardly of the surface of the backing element presents an objectionable protuberance which in some cases interferes with the engagement of the lobe of an ear of the wearer between the surface of the backing element and the spring clip. In the second place, the permissible length of the trunnions engaging the channel of the backing element is limited, since in any case the combined length of the trunnions must be less than the medial spacing between the camming slits. This gives rise to an easy dis-assembly of the resilient clip from the engaging channel which, in time, affects the resiliency of the unit and eventually tends to destroy its desired resilient effect. In the third place, the camming edges are of extended length as a result of the curved contour thereof formed by the extended lateral area of the pressed channel, and thus may result in a comparatively slight movement of the free ends of the resilient clip for the full range of angu 'lar movement thereof, which in some cases may result in the production of a weak and inadequate resilient clampingforce between the backing element and clip.
The present invention seeks to eliminate the faults noted above in my earlier construction. Accordingly, instead of pressing the channel from the external surface of the backing element, camming slits are out directly in the backing element and the channel is pressed inwardly of the backing element, thus eliminating the protuberance on the external surface thereof which might interfere with the clamping action of the body adapted to be disposed between the external surface of the backing element and the resilient clip. Secondly, the camming slits are arranged to flare towards the center of the backing element and the trunnions are disposed outwardly for cooperation with the slits. Thus, the length of these trunnions may be extended to nearly the complete medial spacing between the slits, whereupon a more secure pivotal action is attained, while rendering more difficult the separation of the resilient clip from the backing element, thereby assuring a longer efiective life for the unit. Thirdly, the effective camming slits being in the plane of the backing element, exert a more positive and direct action upon the arms of the clip as they are pressed towards each other in consequence of the pivotal movement of the clip from the plane of the back.
The other objectives of the instant invention are common to those set forth in connection with my previous construction, as fully set forth in the above-mentioned Patent No. 2,377,688, and include the provision of an economical clip construction which requires no soldering, or the handling of sealing plastics or complicated spring structures to adapt a conventional button back 3 for use as a clip which may be used as an earring or other ornament independent of, or in supplement to, a conventional set of buttons having similar ornamentation.
Other objects and purposes will appear from the more detailed description of the invention following hereinafter, taken in conjunction with the accompanying drawing, wherein Fig. 1 is "a front elevation of a button back in accordance with the present invention;
Fig. 2 is a rear view of Fig. 1;
Fig. 3 is a rear View corresponding to Fig. 2 showing the clip in raised position, at which time it exerts its tendency to return to its position shown in Figs. 1 and 2;
Fig. 4 is a vertical sectional view alongline-ti of Fig. 1 with the clip shown solid lines in its normal position, and in dotted lines in its raised position;
Fig. 5 is a perspective view of the spring clip ele- -niem which maybe used with .the button back in accordance with tlie -present invention to complete the economical and rugged assembly; :and
Fig.6 is a perspective view of the finishedearring in accordance with the present invention, illustrating an' ornamental metallic button shell iavihg the fla'ngethereof surrounding the flange cfthem'etallic back.
In Figs. -1 to i of the drawings 'is:shown a ,cireula r button been .i which maybe formed of diet-a1 orany other suitable material, 1having a fla'ng'e i' (Fig. 4) which'is'adapted to embracean ornamental insert "or have spun ,thereover an ornamental shellorbuttontoradapt the ornament to -be usecl as a clip,.-earringor the like. The exter-nalia'ce oi-the button back'is shown-,inFig-l, and' the obverse View thereoi is-showninFig. 2. l he converaingly: directed camming slits; are cut -in' the plane of the backing:'elementandare disposed on one side of the center-of the element andflare towards "the opposite side -thereoi. A trapezoidal channel Bis pressed iromthe surface of the'ba clcing. elementinwardly thereof in order -=to=provide spacesbetween the ends thereof and the cam-ming slits "2 1 into which spaces are adapted'to be his ted theoutwardly' extending trunni'ons 50f a resilient cli iormedofbifurcated "arms i terminating in a common junction pointt. The -configuration iii-the resilient clip which may be formed of any suitable spring wire material is shown" in 5.
I-n-operation, a pivctal mevement oi the-spring clip from its positionsh'ownin Fig. l" and in Fig. i in solid lines, through an angle approximating 90, as'shown in dotted lines' in Fig.4, causes a movement of the ends ofth adjacent to the trunnions towards eachother, whichisresisted by the natural-resilienceof-thebiturcated arms spreading from the'common:junctionpoint 6. 'lTnr'ereiore release of the clip will automatically cause it to return to its original ,pos-itiolrand to resiliently clamp any body -brought: between the clip and the backingelement.
A circular protuberance i ispressed-outwardly from the backing 'elementt equi-distantly below the' carnming slits f andis designed to .cooper ate with the junctionp'ointt of the-resilient clip to enhance the clamping eifect between the-back and the clip.
\Ffnen the clip ii is pivoted aroundtheaxis of its trunnions 5 fromthe plane of the backing element, the ends of the armadjacent to the trunnions travel towards the more restricted spacings between the slits 2', causing a pressing thereof towards'each other againstthe normal resilience. of
the material which gives rise to a force tending to return the clip to its normal unstressed condition. Thus, when the clip 4 is turned upwardly, as is shown in Fig. 4, from its position shown in solid line to that shown in dotted lines for approximately 90, or to the position shown in Fig. 3 from that shown in Fig. 2, the clip tends to assume its normal position adjacent to the back as shown in full lines in Fig. 4 or in Fig. 1. This action is automatic and is very simple in design.
As shown in Figs. 1 and 4, except for the small circular protuberance I, the external surface of the backing element presents no hindrance to the engagement of anybody between the backing element and the resilient clip. Furthermor the trunnionsze may be of extended length and may be nearly the length of the medial spacing between the camming slits 2 and in any case in excess of one-half the length of this medial length which presents a marked advantage over the size of the trunnions which .is permissible with the arrangementshown in my earlier patent.
Furthermore, the camming slits 2 being formed directly in the plane of :the'bacliing element pro- :duoe a-more direct :action upon theends of the .arms of the resilient clip to obtain a more reliable construction thereof.
In Fig. 6 is shown an. ornamental button shell iii spun over a button back oas shown in Figs. -,l to-,4 having aspart thereof a .resilientib'i'fun cated clip i as-sh e wn in Fig. 5. .Caboehons or otherornamental-inserts,of plastic, onyx orother ornamental materials maybe inserted within the confines of the but ton back. and .have the 'flange l' spuntherearoundto retain the same in place.
{Ijhe featuresof the present invention may be appliedtolbutton backs of different geometrical configurations suchas polygonal figures, orany ;other:ornamental or odd ,design. The jeatures of Lthe'inventionare. also applicable to combined arrangements wherein the button backsimay-be .provided vwithstarnped formations or openings toiadapt vthejunits .for interchangeableuse as clips or buttons, as fullydescribedin myearlier .Patent No. 2,377,688.
It is understood that while the invention is particularly, applicable to the adaptability; of con- .ventionalmetallic button backs to the use of :earrings, the features thereof may as well'be applied to..other jewelry clips of an ornamental nature,
,or-to other utilitarianiclips. Also, the resilient clipinay be applied to bacrsof sheet material functioning in the same manner asjsheet .metal backs, which are extensively used at the present time. While 11 haredescribed my invention as -embodied-ina specific form and .as operating in saspecificmann'erfor.purposes of illustration, it vshould.beunderstoodthat I do not limit my in" v.v ention thereto, sincev-arious modifications will suggest .themselvesto those skilled in theart -w-ithout-.departinggfrom.the spirit oimy inven- .tion,.the.scope.oi which is .setiorth in the annexed= claims.
