7 Claims. (Cl. 63-14) The present invention relates to supports for ear ornaments, as well as to combination supports and ear ornaments. Specifically the invention is concerned with improvements in earring assemblies, utilizing the term earring in its commonlyaccepted sense of designating an entire class of ear ornaments.
Conventional earrings of the type which are attached to the lobe of the car by means of clips or crew clamps are possessed of numerous limitations, principal among which is the lack of security of attachment. Careless application of such earrings to the ear is a common occurrence due to the fact that uncomfortable pressure on the lobe of the ear is necessary for secure attachment. As a result, the percentage of lost or damaged earrings is extremely high. When it is considered that earrings are invariably sold in matching pairs it is obvious that the loss of one earring destroys the wearability and worth of the other earring of the pair.
Numerous suggestions have been advanced to overcome the above-noted limitation that is attendant upon the construction and use of conventional earrings, one suggested form of earring comprisingv a base member which is inserted into the concha of the ear and from which the ornament proper is supported externally of the ear structure. Earrings of this type not only are insecure since they rely for their support upon outward pressure against the generally conical concha wall, but additionally they interfere with the transmission of sound waves to the inner ear structure through the auditory canal. Other suggested earrings find their support by using hooks which extend over the ear behind the helix in the manner of eyeglass frames, while still others have hook devices which hang in the intertragic notch and rest by gravity behind the tragus and the anti-tragus, some of them clampingly engaging the tragus and the anti-tragus. Earrings which hook over the helix are cumbersome, uncomfortable and lack the neatness associated with conventional earrings, while earrings which hang in the intertragic notch are susceptible to dislodgment by contact with an upwardly moving object, as for example the upward sweep of a comb or of the hand in arranging the hair.
The present invention is designed to eifectively overcome these various limitations which are associated with conventional earrings of the lobe-clamping type and of the special type briefly outlined above and, accordingly, the invention contemplates the provision of a novel form of ear ornament support or base member having parts which fit within the external ear and which lend a threepoint support for the base member as a whole, as well as for the ear ornament carried thereby. According to the present invention, the three points of support for the base member fit within the ear structure in such a manner that shifting of the support in any direction within a vertical plane is effectively precluded, while at the same time lateral shifting and consequent detachment of the base member from within the external ear structure is also prevented.
More specifically, it is among the principal objects of the present invention to provide a base member or car ornament, all portions of which fit within the external ear structure, and having a first portion which lies behind the tragus and the anti-tragus at the extreme bottom region of the concha, thus bridging the intertragic notch from the inside thereof; a second portion which lies deep in the crevice between the conchaand the auti-tragus and remote from the intertragic notch; and a third portion remote from the two other portions and which extends into the crevice existing between the anti-helix and the concha near the top of the latter and which, in the case of certain human ears, may extend also into the crevice existing between the helix and the anti-helix. The base member is thus, to a large extent, concealed by the anatomical parts of the external ear behind which it lies, and those parts which are not completely concealed by portions of the external ear are in part concealed by the ornament proper and, otherwise, they are substantially hidden from view at most viewing angles.
Another and related object of the present invention is to provide a base member for an ear ornament which is of relatively small proportions so that it presents no excess visible material when viewed from normal angles; which is formed from a substantially transparent plastic material to further enhance its lack of conspicuousness when mounted in the ear; and which is sufliciently resilient and is so designed that it will seek to bottom itself, so to speak, within the ear crevices to which it is applied and thus remain concealed within ear structures which vary appreciably in size and contour.
.Another object of the invention is to provide a base member for an ear ornament and which has associated therewith a spring loaded retaining part by means of which the base member is automatically adjustable to fit external ear structures which vary widely in their size and shape characteristics.
Yet another object of the invention is to provide a combined ear ornament and base member therefor where in the ornament and member are readily separable, thus enabling the base member to serve as a common support for a series of interchangeable ornaments. By such an arrangement, the user once properly fitted with a pair of base supporting members may selectively choose ornaments to match various ensembles without necessitating the purchase of more than one initial pair of base members.
Another object of the invention, in an ear ornament assembly of the character briefly outlined above, is to provide a novel separable attachment means between the base support and the ornament proper including male and female counterpart devices 'and wherein the male fastening device is aflixed to the base member and serves the additional function of providing a convenient manipulating handle whereby the base support may conveniently be applied to the external car.
Another object of the invention in an ear ornament assembly. is to provide a base ornament support which possesses a sufiicient degree of stability when operatively applied to the external ear that it will support ornaments of considerably heavier construction than is possible in connection with earrings of the clip-on type.
Yet another object of the invention is to provide such an ear ornament assembly wherein the separable fastening device is so disposed on the base member that it projects through the intertragic notch and is substantially concealed therein from view.
A further object of the invention is to provide such an ear ornament assembly wherein the weight of the ornament and its base supporting member is widely distributed over the'surface of the external ear so that no pull will be felt by the user on any part of the ear and so that no discomfort will be apparent to the user.
The provision of an ear ornment assembly which is extremely simple in its construction and which therefore may be manufactured at a relatively low cost; one which is comprised of a minimum number of parts, particularly moving parts and which therefore is unlikely to get out of order; one which, despite its light weight and relatively small mass, is rugged and durable and which therefore is possessed of a long life; one in which the component parts thereof are readily susceptible to injection or other plastic molding operations; one which is attractive in its appearance and pleasing in its design, and one which otherwise is well adapted to perform the services required of it, are further desirable features which have been borne in mind in the production and development of the present invention.
Other objects and advantages of the invention, not at this time enumerated, will become more readily apparent as the following description ensues.

' Referring now to the drawings in detail and in particular to FIG. 3, as a preliminary introduction to the present invention, a right human external ear has been disclosed in this view and designatedin its entirety at E. It is to be noted that the tragus a is a small lobe-like eminence which projects rearwardly over and is spaced slightly from the depression b which leads to the external auditory canal. The anti-tragus c'is a similar small lobelike eminence which opposes the tragus and which projects rearwardly and likewise is spaced slightly from the depression b. The tragus and anti-tragus are separated by socalled intertragic notch d. Both the tragus and the antitragus are formed of relatively firm cartilage and are thus fairly firm so that they constitute suitable spaced anchorage flanges within the lower region of the concha e behind which a portion of an ornament-supporting base member, such as the member designated at 10, may be securely nested.
Still referring to FIG. 3 in the upper regions of the.
external ear E, the relatively flexible helix f bounds the upper margin of the ear, faces forwardly, and overlies the anti-helix g. The latter, in turn, overlies the upper margin of the concha e. The anti-helix g is formed of hard cartilage and this portion of the car, being slightly spaced from the concha, defines a recess or pocket within which another portion of the ornament-supporting base member 10 is nested. The forward upper region of the antihelix g in a large percentage of human ears passes under the extreme forward region of the helix and, in combination with the latter, establishes a notch such as has been designated at m and which will hereinafter be referred to as the interhelix notch, such term being coined merely for descriptive terminology herein since there is no medical authority for it.
Returning now to the intertragic notch d, the depth of the pocket n which exists behind the anti-tragus c is of appreciable magnitude and this pocket is more remote from the auditory canal than is the pocket which lies behind the tragus a. This pocket is thus suitable for the nesting of a third portion of the ornament-supporting base member 10.
With the base member 10 thus nested within three fairly widely spaced pockets within the external ear structure, a three point suspension is provided for the base member as a whole, and for any ornament which may be applied to the base member. Furthermore, since the three pockets or recesses generally oppose one another or, in other words, face toward a common central region, these pockets serve to maintain the base member against shifting in any direction in a vertical plane as well as against rotation in a vertical plane.
A complete ear ornament assembly has been illustrated in FIG. 1 and, briefly, it is comprised of two principal parts including the previously mentioned base member 10 and an ornament proper 12. The base member 10 and ornament 12 are separable, the assembly and separation thereof being made possible by a separable male-female connector assembly 14 (see also FIG. 9) which will be described in detail presently.
The ornament 12 illustrated herein is exemplary of a typical ornamental design and it may assume numerous forms and contours. Whatever form the ornament 12 may assume, it is essential that the same be smooth on f base member 10 is so disposed within the external ear that the male portion of the separable connector assembly 14 is'in register with the intertragic notch from the inside of the ear, and the ornament 12,canies the female portion of the assembly 14 at a location where when it is projected through the intertragic notch and caused to become coupled with the male portion, the ornament overlies portions of both the tragus and the anti-tragus, the extent of such overlying being, of course, dependent upon the specific size of the ornament.
Referring now to FIGS. 4 to 8 inclusive, and in particular to FIGS. 4 and 5, the base member 10 is comprised of two principal parts, including a curved part 20 which hereinafter will be referred to as a strut inasmuch as it extends across the outer ear inside the overall cupshaped ear cavity from the lower region to the upper region thereof. Specifically, it extends between the intertragic notch d and the herein termed interhelix notch m. The lower end of the strut 20 is in the form of a small flattened nodule 22 of hollow and somewhat flattened and therefore disk-like design (see also FIGS. 11 and 12) and it is designed to encase certain spring-biasing mechanism, the nature of which will be made clear presently. The nodule 22 fits snugly within the relatively deep pocket (FIG. 2) which lies within and behind the anti-tragus and the tragus.
The upper end 24 of the strut 20 is generally of hook shape design and it is likewise somewhat flattened. In some cars it will extend into the crevice existing between the helix 7 and the concha e; in others it will extend into the crevice between the anti-helix g and the concha. In
most cars it will underlie both the helix and the anti-helix and thus fit in the pocket behind the interhelix notch m. The medial region of the strut 20 between the two notches d and m is more or less oval in transverse cross passes partially across the concha e. The strut 20 is not conspicuous within the ear inasmuch as it is formed of a transparent plastic material such as Lucite or thelike and, if desired, it may be faintly tinted a fiesh color. With the upper and lower ends of the strut 20 nested within respective pockets at widely spaced regions across the ear, and with the bowed medial region thereof resting against the concha e, the strut is prevented from turning about a vertical axis in one direction. It is prevented from turning about such axis in the other direction by means of a spring biased lever arm 26.
The lever arm 26 is formed of a plastic material similar to that of the strut 20 and it is molded about the distal end of one leg 28 of a V-spring 30 (FIGS. and 11) having one or more loops 32 constituting the bight portion thereof. The loops 32 extend around a central shaft 34 which is seated within opposed bosses 36 provided internally of a cylindrical chamber 38 formed in the hollow nodule 22. The other leg '40 of the V-spring 30 is confined within an elongated channel 42 provided internally in the proximate end region of the bowed strut 20. As a manufacturing or molding expediency, the strut 20 may be formed in two sections as shown in FIG. 12, one section 50 being in the form of a cap member and the other section 52 constituting the remainder of the strut 20.
The seam line where the two sections are adhered together by a suitable adhesive or solvent is shown at 54. Both sections are relieved to provide a slot 56 through which the leg 28 of the V-spring 30 as well as the proximate region of the spring biased lever arm 26 project radially outwardly as best seen in FIG. 12.
As shown in FIG. 5, the lever arm 26 is substantially straight and the distal end region 58 thereof is in the form of a flattened nodule. When the strut 20 is properly disposed within the ear structure as previously described with its ends in the vicinity of the notches intertragic and interhelix notches d and m respectively, the lever arm nodule 58 fits behind the anti-helix c in the crevice which exists between the anti-helix and the lower region of the concha e.
Referring now to FIGS. 9 and 12 wherein the details of the separable connector assembly 14 are best illus- 'trated, this assembly constitutes an important feature of the present invention in that the male part 18 thereof constitutes a convenient protuberance by means of which the base member 10, as a whole, may be manipulated when installing the same within the external ear. The male member 18 is in the form of an elongated post of I- shaped configuration in transverse cross section and it includes spaced flanges 60 and 62 connected together by a medial web 64. The web diminishes. in thickness toward one end of the member and the narrow end of the web, as well as the adjacent ends of the flanges 60 and 62,
are secured to a face of the hollow nodule 22 in any suitable manner as for example by an adhesive.
The female counterpart 16 of the assembly 14 is in the form of a wide spring clip 70 which is generally of U- shape in longitudinal cross section and has outwardly flared free edges 72. The cross sectional shape of the member 16 is conformable to the longitudinal cross sectional shape of the web portion 64 of the male part 18 of the connector assembly 14. The part 16 is adapted to be forced over the web 64 and be centered between the flanges 60 and 62 when the two parts are assembled.
The bight portion 74 of the female part 16 is adapted to have an ornament such as the exemplary ornament 12 permanently attached thereto and accordingly the bight portion may be flattened as at 76 to facilitate soldering of the ornament thereto in case the clip 16 and male part 18 are formed of metal, or to facilitate the adhesive bonding of the ornament in case the clip and male part are formed of a plastic material. It is contemplated that in marketing the ear ornament of the present invention a purchaser will be supplied with a pair of the base members 10, one constructed to fit the right external ear and the other constructed to lit the left external ear, and that a large variety of the ornaments 12 be made available in pairs for selective attachment to the base members by means of the separable connector assembly 14 described above.
In the application of the base member 10 to the external ear, the male part 18 of the connector assembly 14 may be employed as a manipulating handle since it projects laterally outwardly from the nodule 22 a sufficient distance to enable it to be grasped between the thumb and forefinger. Since it is non-cylindrical in its contour, the necessary degree of torque may be applied to the base member as a whole to properly orient it while inserting it into the overall ear cavity. Present day ear ornaments or hearing .aid devices which employ base members that fit into the external ear cavity and which have detachable ornaments or hearing aid chassis applied thereto usually employ snap fasteners which are circular in transverse cross section and in which the female part of the fastener is carried by the base member so that it is necessary when applying the base member to the ear to grasp the body of the base member. awkwardness in many instances. Particularly where the finger nails of the user are unduly long, there is the danger of scratching or gouging the external car.
When using the male part 18 of the connector 14 as a manipulative handle as described above, the lever arm 26 may first be inserted into the crevice behind the antitragus, after which the spring 30 may be placed under tension to enable the strut 20 to be swung closer to the arm 26 and the distal book 24 to be unserted behind the interhelix notch m. The male part 18 of the separable connector 14 will then project through the intertragic notch d ready for application thereto of the clip or female part 16 and its attached ornament 12.
The pressure exerted by the spring 30 is not great and it is just sufficient to maintain the nodule 58 at the distal end of the lever arm 26 in position within the crevice behind the anti-tragus and to maintain the book 24 at the upper end of the strut 20 within the crevice which lies behind the antihelix notch. The base member is thus automatically adjustable to fit a wide variety of ear sizes and shapes so that it is not required that it be manufactured in more than three or four different sizes to fit the entire range of human ear dimensions. With the three portions of the base member, namely the nodule 22, the nodule 58 and the book 24 disposed behind respective tissue or cartilage portions of the ear which overlie the concha e, the base member is securely held within the external ear against dislodgement outwardly or against shifting in any direction in a vertical plane, as well as against turning movement about a vertical axis.
The invention is not to be limited to the exact arrangement of parts shown in the accompanying drawings or described in this specification as various changes in the details of construction maybe resorted to without departing from the spirit of the invention. Therefore, only insofar as the invention has particularly been pointed out in the accompanying claims is the same to be limited.
