A self-defense device 10 according to an exemplary embodiment of the present disclosure is illustrated in FIGS. 1-11. The exemplary self-defense device 10 includes a body 12. The exemplary body 12 includes an outer surface 14. The exemplary body 12 includes a forward portion 16 and an aft portion 18. The exemplary outer surface includes a surface area 20 defined by the forward portion 16 and a surface area 22 defined by the aft portion 18.

The exemplary forward portion 16 and exemplary aft portion 18 are releasably engageable with one another. The exemplary forward portion 16 and exemplary aft portion 18 are interconnected by a hinge 24 with a hinge axis 26. The exemplary forward portion 16 defines a forward mating face 28. The exemplary aft portion 18 defines an aft mating facing 30. The exemplary forward and aft mating faces 28 and 30 abut one another when the exemplary forward and aft portions 16 and 18 are pivoted together about the exemplary hinge axis 26 into an operating configuration. The operating configuration is shown in FIG. 1. The exemplary forward and aft mating faces 28 and 30 are offset from one another when the exemplary forward and aft portions 16 and 18 are pivoted apart about the exemplary hinge axis 26 into a loading configuration. The loading configuration is shown in FIG. 2. FIG. 2 shows the exemplary forward and aft mating faces 28 and 30 offset from one another.

The front and aft portions 16, 18 can be releasably connected with a lock 140. The lock 140 can include a hook 142 associated with the exemplary front portion 16 and a catch 144 associated with the exemplary aft portion 18. The catch 144 can be spring-biased into the locking position. A user can press down on the catch 144 to release the hook 142.

The exemplary body 12 is graspable and suspendable by human hand when in use. The exemplary body 12 is graspable by hand in that at least a portion of the exemplary body 12 can be surrounded by at least one hundred eighty degrees by a human hand. The body 12 can be grasped and lifted by a single human hand. The body 12 is suspendable by hand in that the body 12 is sufficiently light-weight so that the self-defense device 10 can be held in an elevated position during use, such as above the user's head or at the height of the user's head. Examples of other devices that are graspable and suspendable by human hand are flashlights.

The exemplary self-defense device 10 includes a gun barrel, such as exemplary gun barrel 32. The exemplary gun barrel 32 is partially housed in the body 12. The exemplary gun barrel 32 includes an interior surface 34 extending along a longitudinal axis 36 between an entry port 38 and an exit port 40. The exemplary exit port 40 is not enclosed by the exemplary body 12. A round of ammunition, such as referenced at 42, can be received in the exemplary gun barrel 32 and fired out of the exit port 40. FIG. 2 shows the round 42 during insertion in the gun barrel 32 and FIGS. 8A and 8B shows the round 42 seated for firing. Thus, the exemplary interior surface 34 of the exemplary gun barrel 32 and the exemplary outer surface 14 are respectively defined by separately-formed and subsequently joined structures. The exemplary gun barrel 32 is replaceably engageable with the exemplary body 12. In other words, the gun barrel 32 can be changed as often as desired or needed without having to replace the body 12.

The exemplary self-defense device 10 includes a trigger assembly, such as exemplary trigger assembly 44. The exemplary trigger assembly 44 includes a trigger 46 and a firing pin 48. The trigger assembly 44 can be at least partially housed in the body 12. The exemplary trigger assembly 44 is housed in the aft portion 18 proximate to the exemplary gun barrel 32. The exemplary firing pin 48 is selectively moveable to engage the round 42 positioned at the exemplary entry port 38.

Referring now to FIGS. 9 and 10, the exemplary trigger assembly 44 also includes a first spring 50, a second spring 52, a latch 54, a third spring, and a fastener 56. The exemplary firing pin 48 extends through an exemplary aperture 58 in the exemplary aft portion 18 of the exemplary body 12. The exemplary aperture 58 defines a shoulder 60. The exemplary first spring 50 is positioned between the shoulder 60 and a flange 62 defined by the firing pin 48. The exemplary first spring 50 biases the firing pin 48 toward a cocked position that is shown in FIG. 9 and away from a firing position that is shown in FIG. 10.

The exemplary aperture 58 also defines a threaded portion 64. A fastener 66 is threadingly engaged with the exemplary threaded portion 64. The exemplary second spring 52 is positioned between the flange 62 defined by the firing pin 48 and the fastener 66. The exemplary second spring 52 biases the firing pin 48 biases the firing pin 48 away from the cocked position that is shown in FIG. 9 and toward the firing position that is shown in FIG. 10. The exemplary second spring 52 exerts a great force on the firing pin 48 than the first spring 50 and can overcome the force generated by the first spring 50.

The exemplary 54 latch is mounted in a slot in the firing pin 48. The exemplary 54 latch can be recessed in the firing pin 48, as shown in FIG. 10, and thereby be flush with an outer surface of the firing pin 48. The exemplary 54 latch can also pivot away from being recessed in the firing pint 48, as shown in FIG. 9. The third spring can be mounted between the firing pin 48 and the latch 54 and bias the latch 54 away from being recessed in the firing pint 48. The third spring has not be shown due to its small size relative to the other structures.

The exemplary fastener 56 can interconnect the trigger 46 and the firing pin 48. The exemplary fastener 56 passes through an aperture 68 defined in the trigger 46. The exemplary fastener 56 is threadingly received in a threaded aperture 70 defined by the firing pin 48. A portion of the firing pin 48 also passes through the aperture 68. A head of the exemplary fastener 56 is positioned in an aperture 72 of the trigger 46.

The trigger assembly 44 can be cocked by the user by pulling the trigger 46 along the axis 36 and away from the body 12. A bottom surface 74 of the aperture 72 acts on the head of the fastener 56 to draw the firing pin 48 against the second spring 52. At some point during this movement, the latch 54 is released from being recessed in the firing pin 48. The latch 54 will then catch on the fastener 66 and prevent movement of the firing pin 48 toward the firing position. This is shown in FIG. 10.

When the self-defense device is fired, the user can press the trigger 46 toward the body 12. Initially, the trigger 46 will move relative to the fastener 56 and the firing pin 48. The surface 74 will separate from the head of the fastener 56. As the movement of the trigger 46 along the axis 36 continues, the aperture 68 will act as a cam and the latch 54 will act as a cam follower. The aperture 68 will force the latch 54 against the third spring and into being recessed in the firing pin 48. When the latch 54 is recessed and can clear the fastener 66, the firing pin 48 is released to the biasing force being applied by the second spring 52 and is driven into the round 42.

The exemplary self-defense device 10 includes at least one forward light, such as exemplary light 76. The exemplary light 76 is a light emitting diode (LED). In the exemplary embodiment, the self-defense device 10 includes a plurality of forward lights disposed proximate the exit 40 and disposed about (around) the axis 36.
