Definitions

  • This invention relates to various constructions for pierced earrings and more particularly to a one-piece pierced earring construction which is quickly, securely and easily locked in position.
  • the clip-on type earring is the clip-on type earring.
  • the second category of earrings is the pierced ear type, and represents earring type to which this application is directed.
  • pierced earrings have been used at least since the turn of the century, little change or innovative variations has been realized in the systems used to securely mount the earring in the pierced ear of the user.
  • the typical configuration found in pierced earrings for the last hundred years is a solid, elongated shaft or stem, to which the particular decorative portion of the earring is secured, with a locking mount or a holding nut slidably engagable along the elongated shaft for attachment thereto.
  • various alternative constructions for the holding nut of this common type of pierced earring has been developed through the years, all of these holding nuts suffer from common deficiencies.
  • Driscoll '033 a one-piece earring holding shaft is disclosed, but without the use of any pivoting or moving portions formed thereon. Instead, Driscoll '033 teaches a one-piece earring shaft construction extending from the ornament, and incorporating a combination of angular bends.
  • Driscoll '033 does teach a system which eliminates the difficulties presently encountered with lock nuts, the Driscoll '033 system requires the user to manipulate the earring in a variety of alternative positions, to insert the elongated peculiarly convoluted shaft into position, with the convoluted portions thereof performing the holding function. Due to the high degree of dexterity and unnatural manipulated movements required in order to completely insert the construction taught by Driscoll '033, this construction has not received popular acceptance.
  • Driscoll '034 another holding system is taught for a pierced earring wherein two or more pendants are required and are supported by nylon filaments connected to a cylindrically-shaped toggle.
  • the independent toggle is inserted through the pierced ear and, when one of the pendants is pulled, assumes a locking position.
  • the pendant connected to the terminating end of the toggle is pulled, aligning the toggle for removal through the pierced ear.
  • this system is extremely limited in that it requires the use of flexible filaments which are positioned in the ear when the earring is worn. This is generally undesirable and unwanted by users.
  • the dual-pendant construction which is required to properly operate the toggle is extremely limiting and prevents a pierced earring construction which will accommodate the majority of present- day pierced earring designs.
  • Another object of the present invention is to provide a pierced earring holding system having the characteristic features defined above having a one-piece construction with the locking portion integrally formed with the pierced earring shaft.
  • Another object of the present invention is to provide a pierced earring holding system having the characteristic features defined above which can be employed on all pierced earring designs regardless of the size or shape or construction of the visible ornamentation.
  • a substantially straight, elongated shaft is mounted to the particular ornament, or to the holding receptacle for the ornament, with the shaft incorporating a terminating portion which is pivotally engaged with the remainder of the shaft.
  • This pivotal portion which forms the terminating end of the shaft, is readily moveable between a first position in which the axis of the pivotal portion substantially coincides with the axis of the elongated shaft, to a second position wherein the axis of the pivotal portion is substantially perpendicular to the axis of the elongated shaft.
  • the pierced earring holding system of the present invention is easily inserted in the pierced ear of the user, in the conventional fashion, with the pivotal portion in its first position.
  • the entire shaft comprises a substantially straight elongated member, which is quickly and easily inserted into the pierced ear of the user without any difficulty being encountered by the user.
  • the pivotal, terminating end portion of the shaft is quickly and easily pivoted into the second position, forming a locking arm which prevents egress of the supporting shaft from the pierced ear.
  • the one piece, unitary self-locking shaft of the present invention assures complete locking engagement in the pierced ear of the user, without requiring any unconventional or difficult manipulative effort by the user, while also eliminating the need for employing any independent piece which can be dislodged or lost during use.
  • the invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.
  • FIGS 1 and 2 one embodiment of the pierced earring holding system of 20 of the present invention is shown mounted to a conventional earring ornamental design structure 21, for exemplary purposes only, design structure 21 is shown as a ring.
  • earring holding system 20 and its associated ring 21 is shown mounted in its securely engaged position in the pierced ear of a user.
  • Pierced earring holding system 20 of the present inventio incorporates a thin, elongated shaft 22 and a locking bar 23 pivotally engaged with shaft 22.
  • Locking bar 23 is mounted to the distal end of shaft 22 by suitable securement means, such as a pivot pin 24.
  • bar 23 preferably comprises smoothly rounded edges and corners and a thickness which is sufficiently less than the diameter of shaft 22 to allow pivoting ease of bar 23. With this construction, locking bar 23 is capable of arcuate movement about the axis defined by pivot pin 24, as well as being smooth constructed for ease of insertion and removal from a pierced ear.
  • this embodiment of pierced earring holding system 20 incorporates a shaft 22 having a suitable recess 25 form therein for accommodating a portion of bar 23.
  • Recess 25 accommodates a portion of bar 23 when bar 23 is pivoted into position with its longitudinal axis substantially coincident with the central axis of shaft 22.
  • holding system 20 of the present invention forms a substantially continuous elongated shaft.
  • Recess 25 can take many different constructions, dependii upon the particular construction for bar 23.
  • bar 23 is mounted to shaft 22 substantial: midway along the length of bar 23, and is pivotable into recess 25 in either direction.
  • shaft 22 preferably incorporates elongated arms 27 extending from the major portion of shaft 22, with these arms being in juxtaposed spaced facing relationship to each other. The space formed between facing arms 27 comprises recess 25.
  • bar 23 is fully rotationally about axis -24, capable of both entering recess 25 from either direction, as well as completely passing through recess 25.
  • Pierced earring holding system 20 of the present invention is securely mounted to ring 21, or any other design structure, in the conventional manner.
  • shaft 22 extends into an accommodating hole formed in ring 21, and is affixed thereto in a conventional fashion, such as brazing.
  • pierced earring holding system 20 can be employed with any pierced earring design, regardless of its physical structure, by merely affixing holding system 20 to the particular design structure using present state of the art techniques employed for the conventional elongated straight shafts requiring locking nuts.
  • FIGs 3 and 4 the quick, easy and efficient insertion and locked engagement of the pierced earring holding system 20 of the present invention in a pierced ear can best be understood.
  • pierced earring holding system 20 is shown being advanced towards a pierced ear 30 in which a channel 31 has been formed.
  • locking bar 31 pivoted into its aligned position, pierced earring holding system 21 assumes the shape of a continuous straight elongated shaft, which is quickly and easily inserted into channel 31 of ear 30, with ease and simplicity with which pierced earring wearers have become adept.
  • shaft 22 of holding system 20 is located within channel 31 of ear 30, as shown in Figure 4.
  • the user can easily pivot locking bar 23 from' its axially aligned position into its locking position, wherein the longitudinal axis of locking bar 23 is substantial perpendicular to the axis of shaft 22.
  • locking bar 23 has been pivoted through this 90° arc of rotation, the earring is securely engaged and locked in the pierced ear of the user, completely eliminating fear of dislocation, dislodgement, or loss of any separate, removable locking portion.
  • This securely engaged lock position is also represented in Figure 1.
  • the cuff link structure requires a biasing system since a positive force is necessary to resist the various rotation-inducing forces acting upon the locking member during use of the cuff link. If any of these forces were successful, the cuff link could become dislodged from the shirt and possibly lost.
  • biasing systems are not . required due to the synergistic interaction of this embodiment of the locking and holding system of the present invention with the user's ear.
  • the user elongates ear 30, when the earring is being inserted, by pulling downward on the ear lobe. This downward force causes channel 31 to widen while also producing an overall thinning of ear 30.
  • locking bar 23 is pivoted from in first, ear inserting position to its second, locked position. Once locking bar has been pivoted to its locked position, the downward force on ear 30 is removed, allowing ear 30 to return to its original length and thickness.
  • elongated shaft 22 comprises an overall diameter of about one millimeter. Furthermore, the overall length of shaft 22, which includes juxtaposed facing arms 27, would preferably be about 7/16 inches long.
  • locking bar 23 Since locking bar 23 is pivotally engaged at the distal end of shaft 22 and has a position wherein a portion of locking bar 23 is coaxially aligned with shaft 22, bar 23 must have an overall thickness less than the one millimeter diameter of shaft 22. Preferably, locking bar 23 comprises a thickness of 0.5 to 0.75 millimeters. Although locking bar 23 may comprise a variety of lengths, it has been found that an overall length of about 5/16 inches assures secure locked engagement of pierced earring locking system 20, while also being easily handled and manipulated by the user.
  • elongated shaft 22 of locking and holding system 20 of the present invention comprises a proximal end similar in structure to the proximal end of the posts presently employed with locking nuts. Consequently, locking and holding system 20 of this invention can be used in each and every design on which straight elongated posts with locking nuts are now being used in pierced earring constructions.
  • locking and holding system 20 comprises a shaft 35 which incorporates a substantially straight portion 36 and a arcuate portion 37, with arcuate portion 37 terminating in an eyelet from which the particular ornament is either directly engaged or suspended by suitable decorative link members.
  • this embodiment incorporates a locking bar 38 which is pivotally engaged in the terminating end of straight section 36 of shaft 35, using a pivot pin 39, with locking bar 38 being pivotally engaged near one of its ends.
  • locking bar 38 pivots between substantially the same two positions, namely a first position wherein the longitudinal axis of bar 38 is substantially aligned with the central axis of straight portion 36 of shaft 38, and a second position wherein the longitudinal axis of locking bar 38 is substantially perpendicular to the axis of straight portion 36 of shaft 35 (shown in Figure 6).
  • the major difference between this construction and the locking bar of the previous embodiment is that locking bar 38 is not capable of pivoting 360° about the pivot axis formed by pivot pin 39.
  • locking bar 38 would be pivoted into its first position with its longitudinal axis substantially aligned with the central axis of straight portion 36 of shaft 35, and inserted in the conventional fashion through the pierced ear of the user.
  • the earring is mounted in its proper position when arcuate portion 37 of shaft 38 is located within the channel of the pierced ear.
  • the user simply pivots locking bar 38 into its second position, with the longitudinal axis of locking number 38 extending substantially perpendicular to the longitudinal axis of straight portion 36 of shaft 35. In this position, the user is assured of secure, locked engagement of the pierced earring in the pierced ear without fear of dislodgement, dislocation, or loss of any separate removable portion.
  • shaft 42 comprises a substantially straight, thin, elongated shaft member with a locking bar 43 pivotally engaged at the distal end of shaft 42.
  • locking bar 43 is pivotally mounted near one of its ends to shaft 42 by means of a pivot pin 44.
  • This construction is similar to the construction discussed above in reference to Figure 6, with this embodiment comprising only an elongated straight shaft 42, similar to the locking and holding system 20 of Figures 2 and 5.
  • the proximal end of shaft 42 is secured to the base of a gemstone holder 46.
  • Gemstone holder 46 is shown with a gemstone 48 securely mounted therein, forming the particular ornament which will be viewable when the pierced earring is mounted in position.
  • shaft 42 comprises a recess 45 formed in the distal end of shaft 42, extending substantially along the central axis of shaft 42, and accommodates the pivoting movement of locking bar 43.
  • recess 45 need only extend a short distance from distal end of shaft 42, since only a small portion of locking bar 43 need move therethrough during the pivoting movements of locking bar 43.
  • recess 45 could extend from the distal end of shaft 42 inwardly, along the shaft's central axis, a distance equal to the entire length of locking bar 43 from pivot pin 44 to the far end of locking bar 43. This construction allows locking bar 43 to rotate 360° about its pivot axis. However, as the length of recess 45 is increased, the solid portion of shaft 42 decreases. This imparts a potential weakness in the overall strength of shaft 42, and is preferably avoided.
  • locking bar 43 is capable of pivoting about pivot pin 44 through an arcuate distance equal to about 270°
  • locking bar 43 preferably is moved between only two major positions, which are about 90° apart.

In Figure 15, wire 81 is shown with substantially equal length segments 83 having been formed but not completely bent into their substantially parallel configuration.
  • Segments 83 are then intertwiningly twisted to form the intertwined, twisted rope-like elongated shaft 82 shown in Figure 16. It has been found that this construction provides a quick and easy assembly procedure while also providing an extremely sturdy, well constructed embodiment for locking and holding system 20.
  • locking bar 23 pivots about a portion of wire 81, thereby eliminating the necessity for use of a separate pivot pin. Furthermore, locking bar 23, as shown in Figure 16, is mounted in a manner which allows complete rotation of locking bar 23 about its pivot axis without affecting the inherent strength or rigidity of shaft 82.

  • locking bar 73 is free to rotate 360° about the axis defined by pivot pin 74.
  • this construction essentially provides 72 with a split, fork-like distal end having two tines or arms 78 in juxtaposed spaced facing relationship, creating recess 75 therebetween.
  • this embodiment can employ a locking bar 73 having two independent sections, represented by phantom sections 76 and 77.
  • this elongated recess embodiment provides locking and holding system 20 with a shorter overall length, it is believed that the increased length of recess 75 imparts a slight reduction in the rigidity of shaft 72. Consequently, although this embodiment can be employed if so desired, the alternative embodiments discussed above are preferably employed.
