The present invention relates to a lift device for a telephone handset, and more particularly to a handset lift device that allows the handset to be lifted by the operation of the lift when a telephone signal is received by the telephone.

As used herein, the term "lift" is defined as a device for lifting and lowering the handset of the telephone slightly upward.

Since the advent of telephones, various accessories have been developed to make telephone usage more convenient and to meet the diverse needs of telephone users. Among these accessories is a cordless telephone. Cordless telephones generally include a base unit and a wireless handset or headset. The base unit is typically coupled to a telephone wall jack or an existing wired telephone set and includes a radio transceiver for transmitting and receiving signals between the base unit and the handset or headset.

Current wireless handsets provide the user with the majority, if not all, of the operating features currently associated with existing corded telephones. These features include the notification of an incoming call, the ability to answer a call, call initiation, dialing a phone number, talking to the other party, and the ability to hang up to end the call. This feature allows the user to rely solely on the wireless handset for all the operating features of all the phones. However, a wireless handset requires the user to hold the handset with one hand or to hold the handset between the user's shoulders and ears, such as a wired handset.

Cordless telephone headsets have emerged as another popular telephone accessory. The wireless headset is worn by a user and typically includes a microphone boom, a microphone, a speaker and a transceiver mounted in the headset that allows the headset to communicate directly with the base unit. As such, the wireless headset allows both hands to be free and to talk to the other party while moving freely within the range of the transceiver.

However, wired and wireless headsets only replace the handset's functions and do not include all the phone's functions. For example, a headset is generally not configured to initiate a call, dial a phone number, or answer an incoming call. As such, the wireless headset typically moves the base unit off-hook to receive an incoming call or on-hook to end the conversation and end the call. It does not provide the ability to control. Thus, there is a limitation to using a wireless headset in that the user must be located near an existing landline telephone set to answer an incoming call. Only after the call has been answered can the user walk around freely while continuing the conversation. The user has to go back to the existing landline telephone to end the call by hang-up.

Wireless headsets are sometimes provided as aftermarket add-ons for existing telephones. As such, wireless headsets made from one source or manufacturer may generally be used with phones made from various sources or manufacturers.

1 shows a state in which a conventional headset system is coupled to a telephone, FIG. 2 shows a prior art instrument device for lifting the telephone handset off-hook, and FIG. 2 shows a prior art device shown in FIG.

An example of a prior art wireless headset system is shown in FIG. 1, where the headset 6 comprises a microphone 6a, a receiver speaker 6b and a transceiver 6c. The headset 6 is designed to allow two hands free telephone conversation once the call is set up. The headset 6 communicates with the base unit 3 coupled to the handset port of the existing telephone 1 by radio frequency signal, and the wireless transceiver 6c powered by a battery is a headset ( 6) is included.

In operation, battery power is removed from the headset 6 when the microphone boom 6d is rotated upwards to be substantially perpendicular to the ground if power is applied from the plug 5. When the boom 6d is turned downward, battery power is provided to the headset 6 so that the user can talk to the other party through the telephone. The headset 6 is designed to be configured for use with the existing telephone 1.

Thus, in order to install the base unit 3, the base unit 3 is electrically coupled to the telephone handset port. The handset 2 is disconnected from the handset port of the telephone 1 and reconnected to the appropriate port of the base unit 3. The headset 6 and the handset 2 can be used interchangeably but not simultaneously. In order to call or answer, the user must remove the handset 2 from the cradle 4.

2 and 3 show a prior art device for mechanically lifting a telephone handset off-hook.

The apparatus shown in FIGS. 2 and 3 is described in US registered patent D358,594. By turning the lever 8, the bar 7 engages the handset 2 and lifts the handset 2 out of the cradle 4 to put the telephone off-hook. Turning the lever 8 in the opposite direction, the handset 2 is put back on the cradle 4 and puts the telephone on-hook. Thus, the device allows the user to manually answer or terminate the call without necessarily removing the handset 2 completely from the cradle 4.

However, the device shown in Figs. 2 and 3 has the disadvantage that the user has to manually lift the handset from the cradle to answer and terminate the call.
