TITLE: TOY GUN HAVING FIRE-CONTROL ASSEMBLY
(a) Technical Field of the Invention
The present invention generally relates to toy or training guns, and
especially relates to an electronic fire-control assembly for such a gun that
can
be quickly replaced.
(b) Description of the Prior Art
There is a sizable market for toy guns as not only boys but also
grown-ups would enjoy having a toy gun. The toy guns are of various varieties
and types such as automatic, semi-automatic, single-shot, repeater, etc. There
are also hand guns, rifles, machine guns, sniper rifles, etc. These various
varieties and types can fit the needs of hobbyists of all ages.
Structurally, a toy gun contains various parts and mechanisms, each for a
specific purpose jointly working together. Taking an automatic rifle as
example, its motor, ratchets, trigger, etc. have to work harmoniously. When a
part or mechanism is out of order, the toy gun has to be disassembled and the
outside parts or mechanisms have to be removed sequentially to reach and
replace the broken one. These steps are tedious and usually a single small
broken part would cause a lot of time and trouble. It is also not uncommon
that
the toy guns after being dismantled cannot be put back together.
FIG 1 is a sectional diagram showing a conventional toy gun. As

illustrated, inside a toy gun 3, there are a number of gears 31, a trigger 32,
and
a mechanical control assembly 33, interacting with each other. When the
trigger 32 is pulled, the mechanical control assembly 33 is engaged to drive
the gears 31 into action so as the file the toy gun 3. As can be imagined, to
replace a broken part in the toy gun 3, the time and effort for disassembly
and
re-assembly is tremendous.

SUMMARY OF THE INVENTION
A major objective of the present invention is to provide an electronic
fire-control assembly that can control the mode, times, and the on/off of the
trigger so as to achieve firing modes such as single-shot,
single-shot-repeated-firing, repeated-firing, and having safety on. The
electronic fire-control assembly can also detect whether there are bullets in
the
magazine or whether the magazine is plugged, so as to enhance the operation
experience of the toy gun or training gun. A magazine detection module, a
shot selection module, and a trigger on/off module are all housed in the
electronic fire-control assembly. When one of the functions breaks down, a
user just replaces the electronic fire-control assembly, instead of spending
time
and effort to inspect, disassemble, and re-assemble the toy gun.
To achieve the objective, a toy gun according to the present invention
contains a power element electrically connected with a driver element and an
electronic fire-control assembly. The electronic fire-control assembly turns
on
or off the driver element, which in turn engages or disengages a gear set. The
electronic fire-control assembly also detects the presence of a magazine and
responds accordingly. The toy gun also contains a trigger and a power
conversion board electrically connected with the power element, the driver
element, and the fire-control assembly. When the trigger is pulled, the
CA 02786475 2012-08-16
4
electronic fire-control assembly is activated. The electronic fire-control
assembly notifies the power conversion board which controls the power
element to provide electricity to the driver element. The driver element
engages the gear set to conduct firing. When there is no bullet in the
magazine
or the magazine is not plugged, the electronic fire-control assembly would
detect the situation and turns off the power provision.
Through the invention, the problems of the prior arts that the toy gun has
to be disassembled in great effort, inspected to find out the broken part, and
that putting the gun back together would also encounter trouble are obviated.
The foregoing objectives and summary provide only a brief introduction
to the present invention. To fully appreciate these and other objects of the
present invention as well as the invention itself, all of which will become
apparent to those skilled in the art, the following detailed description of
the
invention and the claims should be read in conjunction with the accompanying
drawings. Throughout the specification and drawings identical reference
numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not
intended to limit the scope, applicability or configuration of the invention
in
any way. Rather, the following description provides a convenient illustration
for implementing exemplary embodiments of the invention. Various changes
to the described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the invention as
set forth in the appended claims.
As shown in FIGS. 2 and 3, a toy gun 1 according to an embodiment of
the present invention mainly contains a trigger 11, a slide 12, a slide
detection
switch 121 for detecting the position of the slide 12, a magazine 13, a power
element 14 which is a battery in the present embodiment, a driver element 15
which is a motor in the present embodiment and is electrically connected with
the power element 14, a gear set 16 engaged by the driver element 15, an
electronic fire-control assembly 2, and a power conversion board 17
electrically connected with the power element 14, the driver element 15, and
the fire-control assembly 2. A sliding trough (not shown) inside the toy gun 1
is for the slidable configuration of the electronic fire-control assembly 2. A
tenon (not shown) in the toy gun 1 is for locking the electronic fire-control
assembly 2. The electronic fire-control assembly 2 is housed in the toy gun 1
CA 02786475 2012-08-16

and electrically connected with the power element 14. The electronic
fire-control assembly 2 activates or turns off the driver element 15, which in
turn engages or disengages the gear set 16.
The electronic fire-control assembly 2 is housed in an enclosure and
contains a signal conversion board 21, at least a microprocessor 22 configured
on the signal conversion board 21 which provides electricity to the
microprocessor 22, at least a magazine detection module 23 configured in the
microprocessor 22 for detecting the state of the magazine 13 and responding
accordingly, at least a shot selection module 24 configured in the
microprocessor 22, and a trigger on/off module 25 data-linked with the shot
selection module 24 for interacting with the trigger 11.
The operation of the toy gun 1 is described as follows along with FIGS. 2
to 5. As illustrated, a large electrical current is provided by the power
element
14 and is separated by the power conversion board 17 into two currents which
are routed to the driver element 15 and the electronic fire-control assembly
2,
respectively. The current routed to the electronic fire-control assembly 2 is
a
micro current for turning on and off of the electronic fire-control assembly
2.
In addition, the toy gun 1 has an internal heat dissipation element (not
shown)
for releasing the heat produced by the electronic fire-control assembly 2.
When the magazine 13 is plugged into the toy gun 1, the magazine detection
CA 02786475 2012-08-16

module 23 detects the connection between the magazine 13 and the toy gun 1,
and allows the electrical current to conduct through. On the other hand, the
electrical current is blocked if the magazine 13 is not detected so as to
simulate
a real gun. Subsequently, when the slide 12 is pulled, the slide detection
switch
121 detects the slide 12's being pulled and notifies the electronic fire-
control
assembly 2. Then, when the trigger 11 is pulled, the trigger on/off module 25
conducts firing in accordance with the selection of the shot selection module
24, and the firing action is initiated by the driver element 15 with the
electricity provided by the power element 14, and through the gear set 16.
Through the above described structures and steps, the electronic fire-control
assembly 2 is capable of controlling and operating the toy gun 1.
The present invention has the following advantages.
Firstly, the electronic fire-control assembly 2 can control the shots fired
and the on/off of the trigger 11. The electronic fire-control assembly 2 can
also
detect whether there are bullets in the magazine 13 or whether the magazine
13 is plugged, so as to enhance the operation experience of the toy gun or
training gun. The magazine detection module 23, the shot selection module 24,
and the trigger on/off module 25 are all housed in the electronic fire-control
assembly 2. When one of the functions breaks down, a user just replaces the
electronic fire-control assembly 2, instead of spending time and effort to
CA 02786475 2012-08-16
inspect, disassemble, and re-assemble the toy gun.
Secondly, the electronic fire-control assembly 2 provides multiple
operation modes such as single-shot, single-shot-repeated-firing,
repeated-firing, and having safety on.
5 Thirdly, simply through the trough and tenon, the electronic fire-control
assembly 2 is locked in the toy gun. The signal conversion board is placed on
the bottom near the front of the gear set, and can be easily connected with
the
power conversion board, power element, driver element. Its assembly and
disassembly can be achieved without tools and by ordinary users.
