Mobile Phone Patent Abstract
A mobile phone in-call indicator for connecting to an antenna of
a mobile phone is provided. The in-call indicator mainly includes
a lower base having a lower bolt part and an externally threaded
head, an upper base screwed to the threaded head of the lower base
and having a light-emitting diode and a circuit board mounted thereto,
and an ornamental cover rotatably fitted around the upper base to
cover the upper base. In case the in-call indicator is mounted onto
the mobile phone with the ornamental cover facing toward a direction
not exactly the same as that of the mobile phone and therefore resulting
in an inconsistent appearance, the cover may be adjusted in its
direction simply by separating the upper base from the lower base
and turn the upper base relative to the cover.
Mobile Phone Patent Claims
What is claimed is:
1. A mobile phone in-call indicator comprising a lower base, an
upper base, an ornamental cover, and a light-emitting diode and
a circuit board mounted on said upper base; said mobile phone in-call
indicator being characterized in that:
said lower base has an externally threaded bolt forming a lower
part thereof for directly screwing onto a mobile phone, and an externally
threaded head forming an upper part thereof; and that
said upper base has an internally threaded bottom hole for engaging
with said externally threaded head of said lower base; and that
said ornamental cover may be differently designed but always has
a receiving hole provided at a bottom for said upper base to rotatably
mount therein in a tight fit manner while a bottom of said upper
base abutting against an outer periphery of said receiving hole
of said ornamental cover.
Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
Mobile phones are now very popular among the general consumers
to provide convenient communications. The mobile phones even have
been classified by differently shaped appearances, such as cute
model, streamline model, avant-garde model, etc., to meet the consumers'
demands. To meet the diversified appearances of mobile phones, many
peripheral equipment and/or parts of mobile phones, such as the
antenna thereof, are also uniquely designed.
Some of the commercially available mobile phones are so designed
that the antennas thereof are removed and replaced by light-emitting
antenna heads A to indicate in-calls by emitting light. FIG. 1 illustrates
an example of such light-emitting antenna head A. As shown, the
antenna head A includes a base A1 on which a light-emitting diode
A4 and a circuit board A5 are mounted, and a simple cover A3 in
general geometrical shape for housing the base A1 and the light-emitting
diode A4 and the circuit board A5. The base A1 has an integrally
formed lower bolt A2 for directly screwed onto a mobile phone B.
Whereby, when the mobile phone B receives any in-coming call, the
antenna head A emits light to indicate an in-call. Such light-emitting
antenna head A creates a visual entertainment for users and is widely
welcomed by general consumers. And, the covers A3 originally having
only simple geometrical shapes are now changeful in shape to meet
different consumer demands.
The differently shaped covers A3 are fixedly connected to the bases
A1 during manufacture. Consumers select the antenna head A showing
their most favorite design and directly screw the antenna head A
to the mobile phone B.
A problem found with these differently shaped antenna heads A is
the cover A3 might not be consistent with the mobile phone B in
their facing direction after the antenna head A has been fully screwed
onto the mobile phone B. Some of the angularly deviated antenna
heads A even make the mobile phones B looking ugly. This is because
forces applied to screw the antenna heads A to the mobile phones
B vary with users. It is therefore tried by the inventor to develop
an improved light-emitting in-call indicator to eliminate the drawbacks
existing in the conventional antenna heads.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a mobile
phone in-call indicator that does not have the problem of an angularly
deviated cover to spoil an integral appearance of the mobile phone.
To achieve the above and other objects, the mobile phone in-call
indicator of the present invention mainly includes a lower base
having a lower bolt part and an externally threaded head, an upper
base screwed to the threaded head of the lower base and having a
light-emitting diode and a circuit board mounted thereto, and an
ornamental cover rotatably mounted around the upper base in a tight
fit manner to cover the upper base. The in-call indicator is mounted
on the mobile phone by directly screwing the bolt of the lower base
to an antenna of the mobile phone. In case the in-call indicator
is mounted onto the mobile phone with the ornamental cover facing
toward a direction not exactly the same as that of the mobile phone
and therefore resulting in an inconsistent appearance, the ornamental
cover may be adjusted in its direction simply by separating the
upper base from the lower base and turn the upper base relative
to the ornamental cover.
BRIEF DESCRIPTION OF THE DRAWINGS
The above and other objects of the present invention, and the technical
means adopted by the present invention to achieve such objects can
be best understood by referring to the following detailed description
of the preferred embodiments and the accompanying drawings, wherein
FIG. 1 is a schematic sectional view of a conventional light-emitting
antenna head for mounting on a mobile phone to indicate an in-coming
call;
FIG. 2 is an exploded view showing members included in a mobile
phone in-call indicator according to the present invention; and
FIG. 3 illustrates the mounting of the mobile phone in-call indicator
of the present invention onto a mobile phone.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIG. 2 in which a mobile phone in-call indicator
according to the present invention is shown in an exploded manner.
As shown, the in-call indicator mainly includes a lower base 1,
an upper base 2, an ornamental cover 3, a light-emitting diode 4,
and a circuit board 5.
The lower base 1 is used to directly screw onto a mobile phone
(not shown). The lower base 1 includes an externally threaded head
11 forming an upper part thereof and an externally threaded bolt
12 forming a lower part thereof.
The upper base 2 includes an internally threaded bottom hole 21
for receiving and engaging with the threaded head 11 of the lower
base 1. The light-emitting diode 4 and the circuit board 5 are located
and mounted on the upper base 2.
The ornamental cover 3 may be differently designed to show versatile
shapes. A bottom of the cover 3 is provided with a receiving hole
31 for the upper base 2 to rotatably mount therein in a tight fit
manner.
The light-emitting diode 4 and the circuit board 5 are connected
to the upper base 2 during manufacture. The upper base 2 having
the light-emitting diode 4 and the circuit board 5 connected thereto
is then fitted into the cover 3 with the bottom of the upper base
2 abutting against an outer periphery of the receiving hole 31 of
the cover 3.
Thereafter, the lower base 1 is connected to the upper base 2 by
engaging the externally threaded head 11 with the internally threaded
bottom hole 21 of the upper base 2 to complete a mobile phone in-call
indicator of the present invention.
Please now refer to FIG. 3. To mount the above mobile phone in-call
indicator onto a mobile phone B, a user may hold it at the cover
3 and directly screw the bolt 12 at the lower part of the lower
base 1 onto an antenna of the mobile phone B. After the lower base
1 is fully screwed into the mobile phone B, the cover 3 would usually
face toward a direction the same as that of a front of the mobile
phone B to show a consistent appearance.
In the event the cover 3 of the in-call indicator screwed onto
the mobile phone B should face toward a direction not exactly the
same as that of the front of the mobile phone B, the cover 3 may
be adjusted in its direction by separating the upper base 2 from
the lower base 1 and using a suitable tool to slightly turn the
upper base 2 by a suitable degree relative to the cover 3. The adjusted
upper base 2 and cover 3 may then be connected to the lower base
1 again. The adjusted in-call indicator remounted onto the mobile
phone B would now face toward a direction the same as that of the
mobile phone B.
With the above arrangements, the problem of an inconsistent and
non-balanced appearance of the mobile phone caused by an angularly
deviated in-call indicator due to an improper size thereof or an
improper screwing force applied thereto can therefore be avoided.
Meanwhile, the adjustment of the cover 3 does not require frequent
loosening of the lower base 1 from the antenna of the mobile phone
B, threads on the antenna can therefore have longer useable life.
