Abstract
A telephone set comprises a main body and a handset. A storage cavity is formed in the main body for receiving the handset which has a slender body to be inserted into an opening of the storage cavity. A resilient actuator is disposed in the storage cavity and mounted to a hook switch on an electronic circuit within the main body. When the handset is received in the storage cavity, the resilient actuator is pressed to push a button that opens the hook switch to disconnect the circuit of the telephone set. When the handset is removed from the storage cavity, the resilient actuator returns to its free position and releases the button that activates the switch to connect the circuit of the telephone.
Description




FIELD OF THE INVENTION




The present invention generally relates to a telephone set, and more specifically to a telephone set having a storage cavity where a handset can be inserted into.




BACKGROUND OF THE INVENTION




A telephone set generally has a main body and a handset. In a conventional wired telephone, the handset is connected to the main body by a cord. The main body is usually provided with a recessed area on which a hook switch is disposed. When the handset is not in use, it is seated on the recessed area of the main body and the hook switch is opened to disconnect the telephone circuit. To use the telephone, the handset is picked up from the main body and the hook switch is activated to connect the telephone circuit so that a dialing can be started.




A wireless telephone does not use a cord to connect the handset to the main body. In addition to the recessed area on the main body for seating the handset, an on-off button may be provided on the handset so as to send control signals to connect or disconnect the telephone circuit in a remote location.




A problem commonly encountered after using a telephone is that the handset is not seated properly back to the recessed area on the main body of the telephone. Only when a user tries to make a next phone call can he discover that the telephone circuit has been in a busy state for a long time because the handset had not been properly seated back to disconnect the telephone circuit. This often causes inconvenience and make a people miss important calls. There is a strong need to provide a convenient and easy to use mechanism for a telephone set to store the handset and ensure the proper disconnection of the telephone circuit.




SUMMARY OF THE INVENTION




This invention has been made to overcome the above-mentioned drawback of a conventional telephone set. The primary object of the present invention is to provide a telephone set that has a storage cavity for receiving a handset and a hook switch mechanism that disconnects the telephone circuit when the handset is received in the storage cavity.




Accordingly, the telephone set comprises a main body and a handset. The main body is formed with a storage cavity and a resilient actuator disposed in the storage cavity and mounted to a hook switch through a fulcrum. The handset has a slender body that can be received in the storage cavity. When the handset is put into the storage cavity, the actuator pushes a button which opens the hook switch to disconnect the telephone circuit. When the handset is removed from the storage cavity, the resilient actuator returns to its free position and releases the button that actuates the hook switch to connect the telephone circuit.




The foregoing and other objects, features, aspects and advantages of the present invention will become better understood from a careful reading of a detailed description provided herein below with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




With reference to

FIGS. 1-3

, the electronic telephone set of this invention comprises a main telephone body


200


and a handset


100


. The main telephone body


200


includes an enclosure, a dialer


10


, a speech electronic circuit


11


, and a storage cavity


12


. At the upper end of the storage cavity


12


is an opening for receiving the handset


100


. As shown in

FIG. 1

, the handset


100


generally includes a slender body


18


formed with a small condense microphone


17


at the bottom end and a speaker or an earphone at the upper end. A handset cord wire


20


connects the handset


100


to the main telephone body


200


.




As shown in

FIG. 2A

, a first embodiment of the handset


100


of this invention has an earphone


16


formed at the upper end. A second embodiment of the handset


100


as shown in

FIG. 2B

has a speaker


21


formed at the upper end. The cord wire


20


is connected to the microphone


17


and the earphone


16


or the speaker


21


. The handset


100


can be received in the storage cavity


12


by inserting the slender body


18


through the top opening of the storage cavity. The slender body


18


may have a round or polygon cross-section. The bottom end of the handset may have an arc or cone shape.




As shown in

FIG. 3A

, the speech electronic circuit


11


includes an actuator


14


and a hook switch


15


. The actuator


14


is mounted on a fulcrum


29


as illustrated in FIG.


3


A. The actuator


14


is a resilient member which generally forms an angle about 30° with a vertical line when it is in a free position without receiving any pressure.

FIG. 3B

shows a top view of the main body


200


and the actuator


14


in its natural position.




The hook switch


15


has a button


22


formed thereon as shown in FIG.


3


C. When the handset


100


is received in the storage cavity


12


as shown in

FIG. 3C

, the slender body


18


presses the actuator


14


which then pushes the button


22


to open the hook switch


15


and break the telephone circuit. When the handset


100


is removed from the storage cavity


12


as shown in

FIG. 3D

, the actuator


14


is restored to the free position by its elastic force and the button


22


is no longer pushed. The release of the button


22


activates the hook switch


15


into a state that connects the telephone circuit.

FIG. 3D

further illustrates the actuator


14


, the fulcrum


29


, the button


22


and the hook switch


15


. The storage cavity of this invention is generally tubular and can have either a round or a polygon circumference.




As shown in

FIG. 4

, the present invention also applies to a wireless telephone. The wireless telephone according to the invention includes a base station


28


with a battery charger


26


and an antenna


27


, and a mobile phone body


24


which also has an antenna


47


. According to the present invention, a storage cavity is formed in the mobile body


24


and the handset can be received in the storage cavity through a top opening. The principle and operation of the wireless telephone of the invention are similar to what has been described above except that the handset is connected to the mobile phone body


24


by a cord.




Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
