Abstract: Earring having a body, a pin provided at one end of the body and formed with a locking groove, an accessory body provided at the other end to be locked with the locking groove, a handle and a spring. The spring is to be mounted in the lower portion of the accessory body, and the handle is configured to be fitted within the accessory body such that the spring presses at a first end against the inside of the handle and at a second end against the inside of the accessory body. The accessory body maintains an opening for receiving the pin and is formed with an insert groove within the opening into which the pin is inserted, which is elastically locked with the locking groove of the pin by a spring. When the handle is pressed the upper portion of the accessory body opens and the pin is released.

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.

Abstract: A jewelry item including a body, a locking bar provided at one end of the body with a locking groove, and a locker provided at the other end with an insert groove and an internal hinge post. A locking release button is mounted within the locker and rotatable around the internal hinge post. The release button has a first end for engagement of the locking groove and a second pressing end protruding out of the locker. A spring is mounted about the internal hinge post. When the first end of the release button is received within the locking groove in a closed position and the pressing end is depressed, the first end of the release button is rotated against the elastic spring force and the locking bar is decoupled from the locker into an open position.

Abstract: An earring includes an earring body, a locking bar provided at one end of the earring body and formed with a locking groove, and a locker provided at the other end of the earring body to be selectively locked with the locking bar. The locker is formed with an insert groove, the insert groove is provided at an inside thereof with a locking protrusion, and a locking release button is positioned adjacent to the locking protrusion while protruding out of the locker. The spring includes a compression spring and the locking protrusion is adapted to lock with the locking groove of the locking bar while performing a straight movement in a state in which the locking protrusion is elastically supported to the spring. The locking/unlocking operations of the coupling parts are easily performed and an aesthetic appearance of the earring is improved.
