Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention is related to a mobile phone hand-free holder,
and more particularly to an improved structure of a hand-free holder
for a mobile phone, a U.S. Pat. No. 5,903,645 granted to this same
inventor that can be adjusted to hold mobile phone with its plug
socket not provided at the center, and to switch the receiving of
an incoming phone between a cordless earphone or a car radio or
an externally connected loudspeaker.
(b) Description of the Prior Art
Mobile phone has become so popular now either for emergency contact,
business talk or simply having a chat. However, to cope with the
needs for recharging the battery for the mobile phone or to comply
with traffic law that prohibits holding a mobile phone while driving
a car, a holder exclusively for the mobile phone is provided in
a car. At the beginning, such holder was of a box type. It was useful
for a particular model of mobile phone and was comparatively expensive
to have one. Later, a holder was developed to secure the mobile
phone by pressing it in position, such as the one disclosed in U.S.
Pat. No. 5,903,645 patent by this same inventor. It provides improvement
either in linkage of structure, easy access, reduced cost and wide
coverage of application. However, at present, there are more than
a dozen of mobile phone manufacturers, and each is so anxiously
to introduce updated model from time to time. As the plug socket
adapted to the mobile phone varies depending on the manufacturer,
gaps are usually reserved at the center of the base of the holder
while developing the tooling for the manufacturing of the mobile
phone hand-free holder so to cope with various types of adapter
socket from different models. This problem is not so difficult to
be solved. Certain models have not located their plug sockets at
the center for the purpose of permitting expanded functions or having
a unique style design. Such mobile phone prevents from being securely
seated in the holder. Accordingly, another set of tooling must be
developed to suffer disadvantages of higher production cost, limited
range of application, increased inventory of parts and storage capacity.
Furthermore, while receiving an incoming call in the car, one may
not wish the conversation to be overheard by the passenger(s) or
on the contrary, he may wish that all passengers shared the talk
with him. No alternative between private talk and talk over a speaker
is pending improvement. Besides, the plugging in and out of an earphone
would compromise drive safety.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide an improved
structure of a hand free holder for a mobile phone that can be adapted
to a mobile phone with its plug socket not provided at the center
of its base. To achieve the purpose, the holder is respectively
connected to both ends of a cross link pivoted to the center of
the holder; an insertion is provided to the end of the pivot of
the cross link to slide in a lateral slide way in the upper casing;
a coil spring is each provided to both sides of the slide way. The
holder comprised of two identical halves has a serration provided
on the edge of one side of each half. A resilient locking seat in
U-shape is provided by the serration and has two stoppers protruding
into the serration to cause the holder to only press inwardly and
to be secured in position. Consequently, while pressing to hold
the mobile phone in place, the holder is capable of pursuing the
insertion provided to the pivot of the cross link to laterally displace
along the slide way for the press center to deflect for securing
a mobile phone having its plug socket not provided at the center
in position.
Another purpose of the present invention is to provide an improved
structure of a hand free holder for a mobile phone that may switch
the transmission of an incoming call to a cordless earphone if privacy
is desired or to a car radio or an externally connected speaker.
To achieve the purpose, a socket for the cordless earphone is also
provided on the casing of the holder and it also functions as a
switch to control the transmission of an incoming call to a cordless
earphone if privacy is desired or to a car radio or an externally
connected speaker

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the accompanying drawings, a preferred embodiment
of the present invention is essentially comprised of a holder (1),
a resilient locking seat (2), a press lever (4), an upper casing
(3) and a lower casing (5) in a structure is substantially similar
to that disclosed in U.S. Pat. No. 5,903,645. Wherein, the holder
(1) includes two identifiable halves, a right one and a left one
arranged in symmetry to be inserted into where between the lower
casing (5) and the upper casing (3), and respectively connected
to both ends of a cross link pivoted at the center. As illustrated
in FIG. 3, an insertion (16) attached to the lower end of the pivot
(15) of the cross link (12) slides onto a lateral slide way (30)
in the upper casing (3). A coil spring (31) is each provided on
both sides of the lateral slide way (30) and a compression spring
(13) is each provided on both sides between two halves of the holder
(1) or two abutted ends of the cross link (12). One side of each
half of the holder (1) is provided with one-way serration (14) and
the resilient locking seat (2) is provided on the upper casing (3)
by the serration (14). The locking seat (2) indicating a U-shape
has its two stoppers (20) to protrude into the serration (14) to
restrict the holder (1) so that the holder (1) is only able to clamp
inwardly for displacement and hold in position. An inclined indention
(21) is each provided on the rear end of the locking seat (2) to
receive the insertion of a press lever (4) and the press lever (4)
holds against a coil spring (40). An inclined groove (41) is each
provided on one side of the press lever (4) in relation to the indention
(21) from the locking seat (2). An adapter socket (35) is connected
to a gap at the center of the upper casing (3) and an earphone holder
(32) containing an adapter socket (35) is provided at where appropriately
on the upper casing (3) to receive the insertion of a cordless earphone
(34) and to also function as a switch for the control of switching
transmission route of an incoming call. Furthermore, to facilitate
adjusting the orientation for easy access and monitor, a connection
socket (6) is provided at where below the lower casing (5) that
swivels laterally at a certain angle and then gets fixed in position.
In practical use, the swivel connection socket (6) is plugged into
an automobile source socket and adjusted to an orientation where
allows easy access or monitor. Then the press lever (4) is depressed
to make it retreating inwardly, thus displacement takes place at
the inclined groove (41) to push against the inclined indention
(21) for the stopper (20) to move backward and clear away from the
serration (14). Consequently, the fixation force of the holder (1)
disappears and the holder (1) instantly opens up when subject to
the tension from the compression spring (13) until it is drawn by
the cross link (12). Meanwhile, equalization from both coil springs
(31) resting in the slide way (30) of the upper casing (3) push
against the insertion (16) to the pivot (15) of the cross link (12).
The cross link (12) moves toward the center due to the displacement
of the insertion (16) for the center of upper casing (3) is at equal
distance respectively to both halves of the holder (1). Once the
press lever (4) is released, it automatically returns to its original
place due to force from the coil spring (40). In the absence of
the pushing force from the inclined groove (41) with its inherited
resilience to cause the stopper (20) to advance into the serration
(14) to secure the holder (1) in position. Once a mobile phone is
plugged into the adapter socket (35) located between two halves
of the holder (1). As one edge of the holder (1) is provided with
a one-way serration (14), the holder (1) clears away inwardly from
the stopper (20) to slide in one direction, thus to urge the holder
(1) to be synchronously adjusted inwardly in conjunction with the
draw by the cross line (12) to press onto both sides of the mobile
phone, and then the mobile phone is instantly secured in position
with the stoppers (20) from the resilient locking seat (2) protruding
into the serration (14). A mobile phone with its socket not located
at the center can also be rapidly and easily held in place by deflection
of the holder (1). Wherein, the holder (1) is pushed to move to
cause the insertion (16) of the pivot (15) from the cross link (12)
to execute lateral displacement along the slide way (30) in the
upper casing (3); consequently, the center of the holder (1) is
deflected to allow adjustment to such extent that it is overlapped
with the central line of the mobile phone. Furthermore, an adapter
socket (33) contained in the earphone plug holder (32) provided
on the upper casing (3) has dual functions for electricity continuity
and as a switch. It recharges the cordless earphone (34). Meanwhile,
if privacy is concerned in receiving an incoming call, just pick
up the cordless earphone (34) to plug in an ear of the user, the
incoming call is immediately switched to wireless transmission to
be received by the cordless earphone (34). When the cordless earphone
(34) is inserted into the adapter socket (33), the incoming call
may be automatically transmitted with or without wire to an externally
connected speaker or to the car radio to achieve hand-free talk.
The present invention, with its concept and structure having not
yet seen in the market or any publication, permitting a fast and
easy adjustment to hold a mobile phone having its socket not provided
at the center, and hand-free talk either through a cordless earphone
or a speaker to achieve significant advancement of its function
meets the requirements of a utility patent.
It is to be noted that the preferred embodiment of the present
invention is in no way to restrict the present invention, and any
alteration or modification falling within the teaching and characteristics
of the present invention shall be included in the scope of the claims
of the present invention. |
