Abstract

An earring backing assembly including an earring post having a locking groove, a body, a handle and a spring. The spring is mounted on the handle. The handle is fitted within the body such that the spring presses at one end against the handle and at another end against the body. Together the handle and the body maintain an opening for receiving the earring post with the handle maintaining a locking ridge within the opening. The spring biases the locking ridge towards the center of the opening. When the handle is depressed against the pressure of the spring, the handle pivots, moving the locking ridge away from the center of the opening allowing for the earring post to be inserted into the opening. When the handle depression is released, the spring bias returns the locking ridge back towards the center of the opening, engaging the locking groove of the post.

Description

RELATED APPLICATION

This application is based on and claims the benefit of priority from Korean Patent Application No. 20-2012-0003830, filed on May 9, 2012, the entirety of which is incorporated herein by reference.

BACKGROUND

1. Field of the Invention
The present invention relates to an earring. More particularly, the present invention relates to an earring and backing assembly capable of easily performing the locking/unlocking operation of coupling parts and improving the function and ease of use of the assembly.
2. Description of Related Art
In general, jewelry/accessories may be classified into necklaces, bracelets, anklets, and earrings, which are wound on necks, arms, legs of a human body or worn on ears in order to exhibit individual preferences or characters in combination with dresses. Such accessories are diversely designed according to the users' taste and preference and are on sale in the market.
In the case of earring assemblies there is typically provided, at a final coupling point, a primary earring component attached to a post. The post is the portion of the jewelry item that goes through the piercing/hole in the ear. On the other side, typically earring posts are met by a backing or clamp that is used to provide a thicker/stopper region to the portion of the post on the opposite side of the ear, to prevent the post from sliding out of the piercing/hole.
However, existing, coupling/decoupling operations using conventional earring assembly components are very difficult and the coupling parts are not themselves decorative.
For example FIG. 1 is a prior art image showing a typical earring post and backing clip. The post, as shown, is typically a thin straight post, and the clip is typically a small metallic item that includes an opening for accepting the post and some curved/spring wings that press against the post that is pushed through the hole of the clip to make the clip somewhat stick to the post.
However, despite this design, the clip is small and difficult to place on the post. Likewise, the spring leaves on the clip, although providing some pressure still allow slippage on the post, possibly leading to a lost clip and even the earring possibly falling out in such cases. Additionally, the clip is not aesthetically pleasing.

OBJECTS AND SUMMARY

The present arrangement overcomes these drawbacks by providing an earring and backing assembly that is both stable and easy to use while being more aesthetically pleasing than the existing common earring backings.
To this end, the present arrangement provides for an earring backing assembly for mating with an earring post having a locking groove including a body portion; a handle portion; and a spring, where the spring is configured to be mounted on the handle portion and where the handle portion is configured to be fitted within the body portion such that the spring presses at a first end against an inside surface of the handle and at a second end against an inside surface of the body. The handle portion and the body when fitted together maintain an opening for receiving the earring post with the handle portion maintaining a locking ridge in at least a portion of the opening. The spring biases the locking ridge of the handle portion towards the center of the opening, such that when the handle is depressed against the pressure of the spring, the handle pivots, moving the locking ridge away from the center of the opening allowing for the earring post to be inserted into the opening. When the handle depression is released, the spring bias returns the locking ridge back towards the center of the opening, engaging the locking groove of the earring post.

DETAILED DESCRIPTION

In one embodiment, as generally shown in FIG. 2, earring and backing assembly 10 includes earring post 100 and backing 200. Earring post 100 is generally cylindrical in shape and has a locking groove 101 which accepts a corresponding locking ridge 212 from backing 200 as discussed in more detail below.
Backing 200 has an opening 222 for the entry of post 100. Backing 200 is formed by inserting, into an accessory body portion 220, a handle portion 210 in a side by side connection. In the present embodiment, accessory body portion 220 and handle portion 210 are in the shape of a figure eight (8), but other shapes are contemplated, provided they have a substantially similar structure and function.
As shown in FIG. 3, backing 200 houses spring 230 such that when accessory body 220 and handle portion 210 are connected, spring 230 is fixed within backing 200 in handle portion 210 at point 221 which is located below opening 222. One end of spring 230 rests within the lower corner of handle portion 210 and the other end of spring 230 rests within the lower corner of accessory body 220 at an internal cutout 223. As noted above, in the region of opening 222, handle 210 has a locking ridge 212 for catching locking groove 101 on post 100.
Referring to FIGS. 4A and 5A these show backing 200 with handle 210 in a depressed configuration. In this arrangement, handle 210 is pressed by a user compressing spring 230 against the inside 223 of accessory body 220. This causes the upper portion of handle 210 to pivot, outwardly around point 221, resulting in locking ridge 212 moving away from the center of opening 222, making opening 222 large enough to receive pin 100. In this configuration, pin 100 may be inserted into backing 200.
Referring to FIGS. 4B and 53, once post 100 is pushed through opening 222 the user may release handle 210. Spring 230 then biases the lower portion of handle 210 outwardly, resulting in the upper portion of handle 210 pivoting inward causing locking ridge 212 to press inwardly against post 100 (now inside opening 222). In this configuration, locking ridge 212 is pressed into a mating relationship with corresponding groove 101 on post 100 securing it into backing 200.
In a second embodiment illustrated in FIGS. 6 and 7, backing 300 is formed by inserting into a circular accessory body 320 a handle portion 310. Backing 300 houses spring 330. As with the above described embodiment in FIGS. 2-5, such backing is configured to accept post 100 from the earring.
When accessory body 320 and handle 310 are connected, spring 330 is fixed within backing 300 at point 321 which is located in an off-set arrangement relative to 322 (in body 320). One end of spring 330 extends along one side of opening 322 and rests within handle 310 just under a flat pressing portion and the other end of spring 321 extends along the other side of opening 322 and rests within accessory body 320 at point 323 so that opening 322 is within the two ends of spring 330. As described below handle 310 has a locking ridge 311 that is configured to catch locking groove 101 of post 100 as described below.
Referring to FIGS. 8A and 9A these show backing 300 with handle 310 in a depressed configuration. In this arrangement, handle 310 is pressed by a user compressing spring 330 against the inside 323 of accessory body 320. This causes the locking ridge 311 portion of handle 310 to pivot/rotate, around point 321, resulting in locking ridge 311 moving away from the center of opening 322, making opening 322 large enough to receive post 100. In this configuration, post 100 may be inserted into backing 300.
Referring to FIGS. 8B and 9B, once post 100 is pushed through opening 322 the user may release handle 310. Spring 330 then biases the locking ridge 311 of handle 310 to rotate, resulting in handle 310 pivoting in a manner causing locking ridge 312 to press inwardly against post 100 (now inside opening 322). In this configuration, locking ridge 312 is pressed into a mating relationship with corresponding groove 101 on post 100 securing it into backing 300.
In a third embodiment, illustrated in FIGS. 10 and 11, backing 600 is formed by inserting into a shaped accessory body 620, a handle portion 610, Backing 600 houses spring 630. As with the above described embodiment in FIGS. 2-5, such backing is configured to accept post 100 from the earring. In FIG. 10, shaped accessory body 620 is shown in the form of a heart. However, it is understood that the other decorative shapes may be substituted, while maintaining the function and functional elements.
As illustrated in FIG. 12, when accessory body 620 and handle 610 are connected, spring 630 is fixed within backing 600 at point 621 which is located in an off-set arrangement relative to 622 (in body 620). One end of spring 630 extends along one side of opening 622 and rests within handle 610 just under a flat pressing portion and the other end of spring 630 extends along the other side of opening 622 and rests within accessory body 620 at point 623 so that opening 622 is within the two ends of spring 630. As described below handle 610 has a locking ridge 650 that is configured to catch locking groove 101 of post 100 as described below.
Referring to FIGS. 11 b and 12 b which shows backing 600 with handle 610 in a depressed configuration. In this arrangement, handle 610 is pressed by a user compressing spring 630 against the inside 623 of accessory body 620, This causes the locking ridge 650 portion of handle 610 to pivot/rotate, around point 621, resulting in locking ridge 650 moving away from the center of opening 622, making opening 622 large enough to receive post 100. In this configuration, post 100 may be inserted into backing 600.
Referring to FIGS. 11 a and 12 a once post 100 is pushed through opening 622 the user may release handle 610. Spring 630 then biases the locking ridge 650 of handle 610 to rotate, resulting in handle 610 pivoting in a manner causing locking ridge 650 to press inwardly against post 100 (now inside opening 622). In this configuration, locking ridge 650 is pressed into a mating relationship with corresponding groove 101 on post 100 securing it into backing 600. Cap 640 may be connected to accessory body 620 in order to cover the sharp end of pin 100. In the arrangement shown in FIGS. 10-12, handle 610 and shaped accessory body 620 are arranged in a manner to improve the overall aesthetic quality of backing 600. In another embodiment as can be seen in FIGS. 14-18, this arrangement, unlike the above described arrangements of FIGS. 2-9, uses two handle buttons 410 a, 410 b, each one positioned at opposite ends of backing 400, along with two springs 430 a, 430 b.
FIG. 14 depicts backing 400 in a disassembled state. Handle 410 a maintains a pivot point 421 a where spring 430 a is fixed. Handle 410 b maintains a pivot point 421 b where spring 430 b is fixed. As with the above embodiments, handles 410 a and 410 b each include a ridge 423 for supporting the springs 430 a and 430 b.
With springs 430 a and 430 b, handles 410 a and 410 b are inserted into accessory body 420 into opposing slots so that handles 410 a and 410 b protrude from accessory body 420 at opposite ends and handle portions 410 a and 410 b overlap at opening 422 forming the region where post locking groove 101 of post 100 is supported.
As shown more clearly in FIG. 15, each of handles 410 a and 410 b have their own locking ridges 411 a and 411 b which, when arranged within accessory body 420, are oppositely positioned around the central axis of opening 422. As shown in FIG. 15, the post 100 used, with this backing arrangement 400 has two locking grooves 101.
As shown in FIG. 15, locking ridges 411 a and 411 b, are formed as a cupped portion of a triangular structure on the inside of handles 410 a and 410 b respectively. This structure adds structural integrity to the locking arrangement within backing 400, as ridges 411 a and 411 b may be subjected to repeated stresses during operation.
Referring to FIGS. 16A, 17A and 18A these show backing 400 with both handles 410 a and 410 b in a depressed configuration. In this arrangement, both handle 410 a and 410 b are pressed by a user compressing springs 430 a and 430 b against the inside of accessory body 420. This causes both locking ridges 411 a and 411 b of handles 410 a and 410 b to pivot, around points 421 a and 421 b respectively, resulting in locking ridges 411 a and 411 b moving away from the center of opening 422, making opening 422 large enough to receive post 100. In this configuration, post 100 may be inserted into backing 400.
Referring to FIGS. 16B, 17B and 18B, once post 100 is pushed through opening 422 the user may release handles 410 a and 410 b. In this case, both spring 430 a and 430 b bias handle 410 a and 410 b in a manner resulting in locking ridges 411 a and 411 b compressing inwardly from both sides against post 100 (now inside opening 422). In this configuration, locking ridges 411 a and 411 b are pressed into a mating relationship with corresponding grooves 101 on post 100 securing it into backing 400.
In another embodiment as can be seen in FIGS. 19-23, this arrangement, unlike the above described arrangements of FIGS. 2-9, uses two handle buttons 510 a, 510 b, each one positioned at opposite ends of backing 500, along with two springs 530 a, 530 b. Unlike the arrangement in FIGS. 10-14, locking ridges 511 a and 511 are configured as open hook shapes instead of raised ridges of a dosed triangle shape and are further configured to fit into a single locking groove 101 on post 100 as described in more detail below.
FIG. 19 depicts backing 500 in a disassembled state. Handle 510 a maintains a pivot point 521 a where spring 530 a is fixed. Handle 510 b maintains a pivot point 521 b where spring 530 b is fixed. As with the above embodiments, handles 510 a and 510 b each include a ridge 523 for supporting the springs 530 a and 530 b.
With springs 530 a and 530 b, handles 510 a and 510 b are inserted into accessory body 520 into opposing slots so that handles 510 a and 510 b protrude from accessory body 520 at opposite ends and handle portions 510 a and 510 b overlap at opening 522 to form the region where groove 101 of post 100 is supported.
As shown more clearly in FIG. 20, each of handles 510 a and 510 b have their own locking ridges 511 a and 511 b which, when arranged within body 520, are oppositely positioned around the central axis of opening 522. As shown in FIG. 16, the post 100 used with this backing arrangement 400 has only a single locking grooves 101 for receiving the two locking ridges 511 a and 511 b.
As shown in FIG. 20, locking ridges 511 a and 511 b, are formed as cupped or curved open hook shapes with projections from the insides of handles 510 a and 510 b respectively. This structure adds structural Integrity to the locking arrangement within backing 500, by allowing for thick construction of ridges 511 a and 511 b while simultaneously being fit into a single locking groove 101 and being subjected to repeated stresses during operation.
Referring to FIGS. 21A, 22A and 23A these show backing 500 with both handles 510 a and 510 b in a depressed configuration. In this arrangement, both handles 510 a and 510 b are pressed by a user compressing springs 530 a and 530 b against the inside of accessory body 520. This causes both locking ridges 511 a and 511 b of handles 510 a and 510 b to pivot, around points 521 a and 521 b respectively, resulting in locking ridges 511 a and 511 b moving away from the center of opening 522, making opening 522 large enough to receive pin 100. In this configuration, post 100 may be inserted into backing 500.
Referring to FIGS. 218, 223 and 233, once post 100 is pushed through opening 522 the user may release handles 510 a and 510 b. In this case, both springs 530 a and 530 b bias handles 510 a and 510 b in a manner resulting in locking ridges 511 a and 511 b compressing inwardly from both sides against post 100 (now inside opening 522). In this configuration, locking ridges 511 a and 511 b are pressed into a mating relationship with the single corresponding groove 101 on post 100 securing it into backing 500.
In yet another embodiment as illustrated in FIGS. 24-27, backing 700 uses two handles 710 a and 710 b which protrude out of opposite ends of an elongated accessory body 720. Unlike the prior embodiments, where the backings are configured to accept post 100 in a manner perpendicular to the long axis of post 100, backing 700 accepts post 100 in a manner parallel to the long axis of post 100. Two springs 730 a and 730 b are fixed within handle portions 710 a and 710 b respectively. Springs 730 a and 730 b are fixed in a side by side configuration at pivot point 721. One end of spring 730 a rests within handle 710 a and the other end rests on ledge 740 and one end of spring 730 b rests within handle 710 b and the other end rests on ledge 740.
Referring to FIG. 27 b, in this arrangement, both handle 710 a and 710 b are pressed by a user compressing springs 730 a and 730 b against the inside of accessory body 720. This results in locking ridge 711 moving away from the center of opening 722, making opening 722 large enough to receive post 100. In this configuration, post 100 may be inserted into backing 700. As noted above, opening 722 of backing 700 accepts post 100 in a manner parallel to the long axis of post 100.
Referring to FIG. 27 a, once post 100 is pushed through opening 722 the user may release handles 710 a and 710 b. In this case, both spring 730 a and 730 b bias handle 710 a and 710 b in a manner resulting in locking ridge 711 compressing inwardly against post 100 (now inside opening 722). In this configuration, locking ridge 711 is pressed into a mating relationship with corresponding grooves 101 on post 100 securing it into backing 400.
Although the exemplary embodiments of the present Invention have been described, it is understood that the present invention should not be limited to these exemplary embodiments but various changes and modifications can be made by one of ordinary skill in the art within the spirit and scope of the present invention as hereinafter claimed.
For example, according to the present invention, the locking spring mechanism is described as an example for an earring for the purpose of convenience, however, it can be understood that the locking structure can be also applied to a necklace, a bracelet, etc., in addition to the earring.
