Description

DESCRIPTION (a) Technical Field of the Invention [0001] 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 [0002] There is a sizable market for toy guns as not ony 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.

[0003] 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.

[0004] 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.

[0005] EP 1 701 128 A1 discloses an air gun that comprises a magazine, a battery, a motor electrically connected to the battery, a gear train including gears and a rack in operative coupling with the motor, and an electronic control circuit that receives electrical power from the battery and controls the operation of the motor. The electronic control circuit is capable of detecting the magazine and responds accordingly. The air gun comprises a control-circuit-housing case that also houses therein the electronic control circuit and the deceleration mechanism to decelerate the rotation from the motor. The arrangement of the control-circuit-housing case makes it not possible to independently detach the electronic control circuit from the air gun for maintenance and/or replacement.

SUMMARY OF THE INVENTION

[0006] The above mentioned disadvantage of the air gun mentioned in EP 1 701 128 A1 is overcome by the toy gun of claim 1.

[0007] 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.

[0008] 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 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. The electronic fire-control assembly is housed in an enclosure that is separate from the gear set so that the electronic fire-control assembly is independently detachable from the toy gun.

[0009] 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.

[0010] 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 wall 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.
