Abstract

A device for a dry firing training assembly includes a magazine body, and a trigger interface member which protrudes upwards from the magazine body and which is configured to be pushed by an action of pulling a trigger of a firearm into which the magazine body is inserted, the trigger interface member being biased by a biasing member. A pivoting lever is coupled to the trigger interface member. The pivoting lever is arranged to pivot about a pivot and to actuate a sound-producing element.

Description

FIELD OF THE INVENTION

The present invention generally relates to firearms, and particularly to a magazine for firearm trigger control dry firing training.

BACKGROUND OF THE INVENTION

Dry firing is a training method commonly used for weapon training that simulates a weapon's action. The object of dry fire training is to practice trigger control and other weapons manipulation techniques without using live ammunition. Many firearms, such as AR15, AR10, M4 and M16, are single action weapons. For the trigger to release the hammer to strike the firing pin, the action must be cycled to reset or cock the firing mechanism. This cycling is normally done automatically by virtue of the weapon action's normal cycle from firing live ammunition. During dry fire practice, however, current simulation devices require the user to manually work the action to reset the trigger and hammer each time before the trigger can be depressed. This reset is inconsistent with live ammunition fire and thus not desirable for training.
A prior art ammunition magazine is shown in FIG. 1. Their basic construction is a containment shell or magazine body 1 with two open ends. One end is the magazine floor 2, which is covered by a floor plate 3. The opposite end is the feed end, which has a rounds follower 4 that interfaces with the firearm. The inner volume of magazine body 1 contains a magazine spring 5. When ammunition is loaded into the magazine, the ammunition pushes the rounds follower 4 down towards the floor 2 and thereby compresses the spring 5. In use, when one cartridge of ammunition is expended, the compressed spring 5 pushes the follower 4 and the associated ammunition upwards towards the feed end, and the next round of ammunition is thereby readied.

SUMMARY OF THE INVENTION

The present invention seeks to provide a magazine for firearm trigger control dry firing training, as is described further below.
There is provided in accordance with an embodiment of the invention a dry firing training assembly includes a magazine body, a trigger interface member which protrudes upwards from the magazine body and which is configured to be pushed by an action of pulling a trigger of a firearm into which the magazine body is inserted, the trigger interface member being biased by a biasing member, and a pivoting lever coupled to the trigger interface member, the pivoting lever being arranged to pivot about a pivot and to actuate a sound-producing element.
The sound-producing element may include a leaf spring which produces a clicking sound when bent by the pivoting lever pushing against it.
The magazine body may be constructed of two halves secured together with fasteners. The magazine body may include an integral floor plate. The magazine body may include a magazine catch groove.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:

FIG. 1 is a simplified pictorial illustration of a prior art magazine for a firearm;

FIGS. 2A and 2B are simplified front view and perspective illustrations, respectively, of two halves of a magazine body of a dry firing training assembly, constructed and operative in accordance with a non-limiting embodiment of the invention;

FIG. 3 is a simplified perspective illustration of the dry firing training assembly, constructed and operative in accordance with a non-limiting embodiment of the invention; and

FIG. 4 is a simplified perspective illustration of two halves of the dry firing training assembly, showing the internal components.

DETAILED DESCRIPTION OF EMBODIMENTS

Reference is now made to FIGS. 2A-2B, which illustrate two halves of a magazine body of a dry firing training assembly 10, and to FIGS. 3 and 4, which illustrate the dry firing training assembly 10, in accordance with a non-limiting embodiment of the invention.
The dry firing training assembly 10 includes a magazine body 12, which may be constructed of two halves 12A and 12B that can be secured together with fasteners (e.g., screws 11 (FIG. 3) that are received in bosses 13 (FIGS. 2A and 2B)), or other joining methods such as welding, bonding, and others. In the illustrated embodiment, the magazine body 12 does not have a separate floor plate, rather it has an integral floor plate 14, wherein each of the two halves 12A and 12B are integrally formed with half- floor plates 14A and 14B, respectively.
The dry firing training assembly 10 includes a trigger interface member 16 which protrudes upwards from magazine body 12, and which can be pushed by the action of pulling the trigger of the firearm into which the magazine body 12 is inserted. The magazine body may include a magazine catch groove 18 which is caught by the magazine catch of the firearm, as is known in the art. Trigger interface member 16 is biased by a biasing member 20 (FIGS. 3 and 4), such as a coil spring.
As seen in FIG. 4, the trigger interface member 16 is coupled to a pivoting lever 22, which pivots about a pivot 24. The pivoting lever 22 is arranged to actuate a sound-producing element 26, such as but not limited to, a leaf spring which produces a clicking sound when bent by pivoting lever 22 pushing against it. Pivoting lever 22 pushes against the sound-producing element 26 by the action of the firearm trigger moving the pivoting lever 22 in the direction of arrow 27, which compresses the biasing member 20. After pulling the trigger, the biasing member 20 pushes the pivoting lever 22 back to its initial position for the next trigger pull.
Alternatively, other sound-producing elements may be used, such as other mechanical clickers, or electrical clickers (wherein the pivoting lever 22 pushes a switch to activate the electrical clicker). The clicking sound imitates the sound of the trigger, or may even imitate the sound of a round being fired from the firearm.
The device may include a side tab 28, which is coupled to the pivoting lever 22. When the magazine body 12 is inserted in the magazine well of some firearms, if the trigger interface member 16 stays in place, it will abut against a portion of the firearm and the magazine cannot be fully inserted. Thus, the trigger interface member 16 has to move aside in order for the magazine to be fully inserted. This is the purpose of side tab 28. As the magazine slides into the magazine well, the side tab 28 abuts against the inside of the magazine well and this pushes the trigger interface member 16 inwards temporarily so that the magazine can be fully inserted. Once fully inserted, the trigger interface member 16 moves back to its initial position and is now ready to be moved by the action of the trigger, as described above.
The magazine body 12 is formed with a window 29, which allows access to inner components without having to take apart magazine body 12.

Claims

What is claimed is:

1. A dry firing training assembly comprising:
