Abstract

An anti-tangling device includes a headphone cord having a distal end, a male signal plug at the distal end, a proximal end, and at least one earphone at the proximal end. Each of the plug and the earphone has first or second parts of a two-part connection device. The two-part connection device removably secures the plug and the earphone to one another. In an embodiment, the plug is the first part and the earphone has a plug-in portion as the second part. The plug-in portion defines a female port shaped to removably secure the plug therein and, when secured, forms a continuous loop with the cord, the plug, and the earphone. The plug-in portion can be integral with or removably attached to the earphone. The first and second parts can be a magnet and a magnetized piece, a hook-and-loop type fastener, or parts of a press-fit snap fastener.

Claims (32)

1. An anti-tangling device, comprising:

a headphone cord having:

a distal end;

a male signal plug at said distal end;

a proximal end; and

at least one earphone at said proximal end, said earphone having a plug-in portion removably attached therein and defining a female port shaped to removably secure said plug therein and, when secured, a continuous loop is formed by said cord, said plug, and said earphone.

2. The anti-tangling device according to claim 1 , further comprising:

a magnet emitting a magnetic field and a magnetized piece attracted by said field;

each of said magnet and said magnetized piece is secured to a respective one of said plug and said earphone; and

said magnet and said magnetized piece removably secure said plug and said earphone to one another.

3. The anti-tangling device according to claim 1 , further comprising:

a hook-and-loop type fastener having a first and second part;

each of the first and second parts of said hook-and-loop type fastener is secured to a respective one of said plug and said earphone; and

said first and second parts of said hook-and-loop type fastener removably secure said plug and said earphone to one another.

4. The anti-tangling device according to claim 1 , further comprising:

a press-fit snap fastener having a first and second part;

each of the first and second parts of said snap fastener is secured to a respective one of said plug and said earphone; and

said first and second parts of said snap fastener removably secure said plug and said earphone to one another.

5. The anti-tangling device according to claim 1 , wherein:

said plug-in portion is at least one snap ring attached to said earphone by a press fit and operable to removably secure said earphone to said male plug.

6. The anti-tangling device according to claim 1 , further comprising:

at least one additional earphone at said proximal end; and

each of said plug and said earphones having one of first, second, and third parts of a three-part connection device, said three-part connection device removably securing said plug and said earphones to one another.

7. The anti-tangling device according to claim 6 , wherein said three-part connection device is a plate with three sockets shaped to connectively secure a respective one of said plug and said two earphones therein and, when secured, forming a continuous loop with said cord, said plug, and said earphones.

8. The anti-tangling device according to claim 7 , wherein said three sockets are three female sockets shaped to connectively secure therein a respective one of said plug and said two earphones.

9. The anti-tangling device according to claim 8 , wherein said three female sockets are each press-fit sockets shaped to connectively secure therein a respective one of said plug and said two earphones.

10. The anti-tangling device according to claim 6 , wherein said three-part connection device is a set of three snap connections each positioned to connectively secure a respective one of said plug and said two earphones.

11. The anti-tangling device according to claim 6 , wherein said three-part connection device is a three-armed clip individually securing each of said plug and said earphones to one of said arms.

12. The anti-tangling device according to claim 1 , further comprising:

a geometric solid having an outermost edge and defining at least two inlets for said plug and said earphone starting at said outermost edge, each of said inlets forming a press-fit opening operable to removably secure at least one of said signal plug and said earphone therein.

13. The anti-tangling device according to claim 12 , wherein said geometric solid is separate from said headphone cord.

14. The anti-tangling device according to claim 12 , wherein said inlets have a relatively narrow portion and a relatively larger portion expanding from said narrow portion and continuing inwards towards a middle of said geometric solid.
