The hands-free kit of this invention consists of including but not limited to a plastic carrying case, an adaptor, an earpiece set connected to an on/off switch by thin copper wires coated with flexible plastic. The earpiece set of this invention is small enough to be installed inside the cellular phone carrying case of this invention. The earpiece set consists of, including but not limited to, a microphone, an earpiece, electric wire and a mechanical spring winder. The earpiece set of this invention is coiled inside the cellular phone carrying case of this invention by a mechanical spring winder installed inside the case. One end of the earpiece set is connected to the on/off switch, which is connected to the cellular phone via the earphone jack. The other end of the earpiece set is exposed out of the spring winder. The earpiece is holding on the out side of earpiece hole on the back of the case sustaining a strain of the wire connected to spring winder. The earpiece and speaker are stretched out of the carrying case when the user uses the hands-free kit. When the user does not pull out the earpiece, the power supplied only to the cellular phone. The kit is convenient to carry all set in one package. The kit of this invention minimizes losing earpiece set.

[0011] FIG. 2 is a side view of the carrying holder.

[0012] FIG. 3 is a perspective view of the assembly of the spring winder.

[0013] FIG. 4 is a rear view of the carrying holder.

[0014] FIG. 1 is the front view of the cellular phone carrying case. Power is supplied to the phone through the adapter jack port (11). Voice signals are exchanged through the earpiece jack (12). The earpiece jack (12) is connected by a copper wire(16) to the ring connector (13). Dotted drawings (14) and (15) are microphone and earpiece, respectively.

[0015] FIG. 2 is the side view of the carrying case. The barrier (21) separates the cellular phone and hands-free kit. Earpiece (22) and microphone (23) are connected to the spring winder (24).

[0016] FIG. 3 is a perspective view of the assembly of the spring winder. Top element (31) is illustrated as (13) in FIG. 1. It consists of three copper rings separated by plastic and connected to cellular phone by wire (32). Each ring contacts with each copper knobs (33). The knobs are plated on plastic disc (34) and connected to the wire (35). The wire is wound on the winder (36). The winder is on the spring and gear box (37). In the gearbox, a cramp iron (38) is located on a rod to stop the gear (40) connected to the spring (41). The other end of the spring is fixed the other rod (39) in the gear box. When a user pulls out the earpiece (22) of FIG. 1, the wire (35) turns the center rod (42). Then the spring, connected to the rods, turns to the anti-clock wise and renders tension to the wire (35).

[0017] FIG. 4 is the rear view of the carrying case. As a user stretches out the earpiece, the radius of circle of wire bundle is reduced. Then the switch connector (43), supported on the surface of wire bundle, moves to the inner circle wise drawn by the coil spring (44) to turn on the switch (45). The cellular phone and earpiece are connected while the cellular phone is hanged on a user's pocket or waistband. The earpiece turns off when the user pulls out a little more of the ear piece and let the spring (41) wind the wire (35) and push the connector (43) clock wise and so the switch (45) are disconnected with the cellular phone.
