Abstract

A holding strap for wireless ear-bud style earpieces having a cylindrical or prismatic stem, includes: a pair of stem housings, each of which is constructed to form a hollow cylinder or prism having a hollow cylindrical or prismatic space to receive the cylindrical stem, wherein the hollow cylinder or prism has an inlet, an inlet rim, an outlet, and an outlet rim; a connecting strap connecting the pair of stem housings; and a strap holder for holding two places of the connecting strap. The hollow cylindrical or prismatic space is sized for the cylindrical or prismatic stem to fit in, and the stem housing is constructed so that the stem passes through the inlet, the hollow cylindrical or prismatic space and the outlet and then, the cylindrical or prismatic stem is retained in the cylindrical or prismatic space of the stem housing by a friction fit.

wherein an area of the connecting strap ( 30 ) that extends from the outlet rim ( 24 ) and abuts the stem ( 120 ) is rounded to correspond to the shape of the cylindrical stem ( 120 ) and be in contact with the stem ( 120 ).

2. The holding strap ( 10 ) of claim 1 , wherein the inlet rim ( 22 ) is tapered toward the hollow cylindrical space ( 25 ) to allow insertion of the cylindrical stem ( 120 ) into the hollow cylindrical space ( 25 ).

3. The holding strap ( 10 ) of claim 1 , wherein the pair of stem housings ( 20 ) and the connecting strap ( 30 ) are made of thermoplastic elastomer, thermoplastic polyurethane, or mixture of thermoplastic polyurethane and silicone.

4. The holding strap ( 10 ) of claim 1 , further comprising a clip for holding the connecting strap ( 30 ) together when the connecting strap is wound.

5. The holding strap ( 10 ) of claim 4 , wherein the clip is configured to attach to a charging case ( 200 ) using an adhesive.

6. The holding strap ( 10 ) of claim 1 , further comprising a strap holder ( 40 ) for holding two places of the connecting strap ( 30 ) together,
wherein the strap holder ( 40 ) comprises:
a first space ( 41 ) and a second space ( 42 ) for respectively receiving first and second places ( 31 , 32 ) of the connecting strap ( 30 );
a first entry space ( 43 ) and a second entry space ( 44 ) wherein the first and second places ( 31 , 32 ) of the connecting strap ( 30 ) respectively enter the first entry space ( 43 ) and the second entry space ( 44 ) to be retained in the first space ( 41 ) and the second space ( 42 );
a dividing wall ( 45 ) which is located between the first and second spaces ( 41 , 42 );
first side walls ( 46 ) abutting opposite sides of the first space ( 41 );
first flange walls ( 48 ) formed on both sides of the first entry space ( 43 ); and
second side walls ( 47 ) abutting the second space ( 42 ) wherein the second side walls ( 47 ) form an “L”-shaped wall extending from the dividing wall ( 45 ),

wherein the first and second spaces ( 41 , 42 ) are sized for the connecting strap ( 30 ) to fit in and be retained therein by a friction fit.

7. The holding strap ( 10 ) of claim 6 , wherein the strap holder ( 40 ) further comprises a second flange wall ( 49 ) abutting one side of the second entry space ( 44 ), wherein the dividing wall ( 45 ) abuts another side of the second entry space ( 44 ).

8. The holding strap ( 10 ) of claim 6 , wherein the connecting strap ( 30 ) comprises first faces and second faces, wherein a width of the first faces is greater than a width of the second faces,
wherein the first and second entry spaces ( 43 , 44 ) have opening widths less than the width of the first faces, and the opening widths of the first and second entry spaces ( 43 , 44 ) are sized to receive the width of the second faces, of which, allow insertion of the connecting strap ( 30 ) into the first and second entry spaces ( 43 , 44 ).

9. The holding strap ( 10 ) of claim 6 , wherein a height of the first side walls ( 46 ) and the first flange walls ( 48 ) is greater than a height of the second side walls ( 47 ) and a second flange wall ( 49 ).

10. A holding strap ( 10 ) detachably coupled to ear-bud style earpieces ( 110 ) having a stem ( 120 ) that is substantially cylindrical, the holding strap ( 10 ) comprising:
