Abstract

A portable phone comprises a handset having a low power radio transmitter and a base station having a booster transmitter that is optionally coupled to the handset for better transmission. A docking cradle has a nest to receive a boat and the boat has a pocket to receive the handset. The boat is connected to the base by a cord and a connector in the boat is coupled to the handset when the handset is seated in the boat. The cradle, boat and handset are nested together for compact hands-free operation, the handset is removed from the boat for portable operation, or the handset and boat together are removed from the cradle for wire-connected hand-held operation.

Claims

1. A telephone for portable wireless handset use and alternate use connected to a base station comprising:

a handset having first radio means for low power wireless communication and contacts for wired communication;

a base station having second radio means for high power wireless communication, and a cord for coupling to the handset;

a docking cradle;

a boat for removably seating in the docking cradle for hand-held operation when removed and having a pocket for receiving the handset; and

the boat having terminals connected to the cord for coupling to the handset contacts for wired communication when the handset is seated in the boat;

whereby the handset can be used alone for communication via the first radio means and alternatively the handset can be mated to the boat for coupling through the cord to the base station for either hand-held or hand-free communication via the second radio means.

2. The invention as defined in claim 1 wherein the boat is a shell which closely conforms to the handset for securely receiving the handset for ease of handling in combination with the handset when removed from the docking cradle.

3. The invention as defined in claim 1 wherein the docking cradle has a cavity conforming to the outer shape of the boat for securely receiving the boat, and includes means for facilitating removal of the handset and boat from the cavity.

4. The invention as defined in claim 3 wherein the pocket of the boat conforms to the outer shape of the handset for securely receiving the handset whereby when assembled the handset, boat, and cradle are integrated into a compact unit.

5. The invention as defined in claim 1 wherein:

the boat has first latching means for securely holding the handset and first spring release means for releasing the handset from the boat; and

the docking cradle has second latching means for securely holding the boat and second spring release means for releasing the boat and handset together from the cradle.

6. The invention as defined in claim 1 wherein:

a speaker and a first microphone are connected to the handset;

an earpiece and a second microphone are within the handset; and

means responsive to the position of the handset relative to the cradle for enabling the speaker and the first microphone when the handset is installed on the cradle for hands-free operation, and for enabling the earpiece and the second microphone when the handset is removed from the cradle for hand-held operation.

7. The invention as defined in claim 1 including:

means responsive to the position of the handset relative to the boat for enabling the first radio means when the handset is removed from the boat and for enabling the second radio means when the handset is installed in the boat.

8. The invention as defined in claim 1 wherein the docking cradle includes cord storage means for paying out cord when the boat is being removed from the docking cradle, and for receiving cord when the boat is returned to the docking cradle.

9. The invention as defined in claim 1 wherein the terminals extend through a wall of the boat and into the pocket for conductive connection to the handset contacts.
