DETAILED DESCRIPTION

U.S. Provisional Application 61/414,203 and U.S. application Ser. No. 13/296,657 are hereby incorporated by reference in their entirety.

Referring now to the drawings in general, the illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.

The present invention provides for a generally tubular-shaped, multifunctional self-defense device, generally described as 100 in FIG. 1. The multifunctional self-defense device includes a blunt end 10 and a sharp end 20. The device is designed to be used as a self-defense striking object. As such, the device is designed to be gripped and preferably contains one or more non-slip sections 30 to prevent slipping when striking. The device is also preferably made from hard, impact-resistant material that can be used to break glass and is also preferably lightweight for ease of carrying. For example, the tubular shape is preferably composed of aluminum, titanium or similar materials. More preferably, the tubular shape is composed of anodized aircraft aluminum or any similar strong material.

The device is composed of first section 40 and a second section 50 that are joined together. The two sections preferably are threaded to screw together. As shown in FIG. 2, the blunt section 40 is further separable to permit the exchange of a battery 60 contained inside the device and the two sections preferably screw together to turn a light on and off. Alternatively, a switch (not shown) can be used to activate the light. The two sections are generally described as a blunt section 40 and a sharp section 50.

The two sections preferably can operate independently of each other. For example, if the blunt section contains a light and the sharp section contains a pen, once the parts are separated the light can still be operated and the sharp section can still be used as a pen or a self-defense weapon. In these cases, the switch to operate the light is completely incorporated in the blunt section. Thus, the device is operable to provide lighting to the user when the user is using the writing device.

The blunt section 40 contains a light source 90 configured so that the device functions as a flashlight. Preferably, the light is a light-emitting diode (LED). As such, the light contained in the blunt section is recessed and/or the blunt end has a lens (not shown) and/or a shield 110 protecting the light. Preferably, blunt end is designed and configured so that the light emitted is not visible laterally. For example, a protective shield xx is solid, rather than perforated.

The blunt section further includes sections housing electronic circuit boards 92 and 94 for controlling an LED light.

All the sections are preferably threaded together. The sections that do not need to be opened or manipulated by a user are preferably locked together using a threadlocking adhesive, such as Loctite adhesives.

The end of the blunt section is smooth to prevent a user from hurting his/her thumb or other digit that is holding the end while striking an object with the device.

The pointed section of the device is pointed such that it will puncture tissue and clothing when struck against these. The pointed section includes large grooves 160, shown in FIG. 3, herein called “blood channels”, to facilitate bleeding upon stabbing.

The pointed section preferably includes a bulbous feature 170 to facilitate bleeding upon stabbing. The bulbous feature 170 is generally shaped like a spear tip or arrowhead.

The pointed section preferably includes tissue-capturing elements for obtaining tissues samples for biological identification. The pointed section preferably includes barbs 180 to capture tissue from an assailant when the sharp end of the device penetrates the assailant's tissue. Deep, narrow grooves 200 are preferably included in the pointed section. The grooves are sufficiently deep and narrow such that they are difficult to clean by merely rinsing and wiping. Thus, the deep narrow grooves make it difficult for an assailant to quickly clean away any tissue samples collected on the device.

The tubular shape preferably includes a writing device 210, such as an ink pen cartridge, that extends from the internal end of the pointed section. The ink pen cartridge is enclosed to prevent damage when the pointed section is being used for self-defense or otherwise to strike an object. Refill pen cartridges are also contained within the pointed section of the pen. In another embodiment (not shown), the pen is reversed, extending out the pointed end, and retractable.

The pointed section also preferably includes threads (not shown), such that accessory devices can be mounted on the flashlight. For example, a firestarter, knife sharpener, hammer head, wrench, and any tool that needs a handle can be mounted on the device. Different sizes of the present invention are possible, as shown in FIG. 4. Smaller versions of the present invention, shown as embodiment A, use a single battery 220 and are sized such that they can be attached to a key chain and not cause an inconvenience. A larger version, shown in embodiment B, uses a larger battery or multiple batteries and is sized more as a writing instrument.

Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. The above-mentioned examples are provided to serve the purpose of clarifying the aspects of the invention and it will be apparent to one skilled in the art that they do not serve to limit the scope of the invention. All modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the present invention.
