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.
