Description

ONE HANDED FIRE STARTING TOOL

This invention relates to a self-contained fire-starting tool that can be manually operated by one hand, producing a high volume of extremely hot sparks of ignited particles of a pyrophoric element.
The hardened steel striker facilitating the friction process against the pyrophoric element to discharge the ignited particles is self-contained within the device. No external tool or object is required to manipulate the action of the device to cause the sparking effect to take place. This increases the user-friendliness of the device in relation to recreational uses and also true survival situations.

BACKGROUND OF INVENTION
There have been several different designs invented with the intention to produce a fire-starting tool based on using a pyrophoric element to generate sparks upon striking or scraping the surface with a sharp metallic object, which in turn ignites a combustible material and starts the fire-lighting process. Many of these inventions are intended to use two hands, one to hold the pyrophoric element and the other to use a striking device against the pyrophoric element, in order to successfully create the fire-starting process. While this may be a simple means of fire starting, both hands are still required in some fashion to be at least moderately successful in causing ignition of combustible materials. There are situations where it would be very advantageous to have a fire-starting tool that could be operated sufficiently with the use of only one-hand. The advantage of such a device can easily be realized in the event that the user only has the functional use of one hand due to injury. There are some designs intended to be used with one hand, there are however also drawbacks associated with the current designs on the commercial market, thereby reducing the user friendliness of the device. One such device is quite small and as such does not generate a substantial quantity of sparks for fire-lighting purposes. Also because of the small quantity of sparks it cannot conveniently be used as an emergency signaling device at night. Nor can someone wearing heavy gloves use it without much difficulty, in an inclement weather environment.
Another style of device is much larger and can generate more sparks, but this comes at the expense of a much heavier, larger, and bulkier package. It also requires a hard surface on which to rest the pyrophoric element in order to initiate the striking process. There are many situations where there may not be a hard enough surface in the surrounding environment to operate the device, in which case two hands are once again required to make the process work, thereby negating the sought after one-handed operation ability. Because this device needs a hard surface to function one-handed, it does not lend itself to being easily used as an emergency signaling device without the use of both hands or potentially burning ones fingers from being to close to the sparks as they are generated.
Some of the previous fire-starting tool designs are:

The current designs have limitations and drawbacks inherent to their designs and are not made to provide both true one-handed operation, with or without gloved hands, and generation of very large quantities of hot sparks to easily ignite a combustible material to start a fire. Nor are they able to be easily used as an emergency signaling device in the event of a survival scenario. These limitations and drawbacks are solved by this current application.

SUMMARY OF INVENTION
This invention relates to a self-contained fire-starting tool that can be manually operated by one hand, producing a high volume of extremely hot sparks of ignited particles from a pyrophoric element. The hardened steel striker facilitating the friction process against the pyrophoric element to discharge the ignited particles is self-contained within the device. No external tool or object is required to manipulate the action of the device to cause the sparking effect to take place. The fire-starting tool is composed of two main bodies interconnected, which contain the mechanisms for generating the hot sparks required to ignite a combustible material. The primary body houses the pyrophoric element, the main action spring and the tinder storage compartment.
It also is designed to allow the secondary body to slide into the primary body housing. The secondary body houses the striker device, which rests against the pyrophoric element, and the tension spring that pushes the striker device up against the pyrophoric element. To operate, the user simply grasps the fire-starting tool with one hand, positioning the frontal portion of the device in the direction he/she wishes the sparks to travel, depresses the secondary body with a finger or thumb into the primary body, thereby compressing the main action spring, and then releases the secondary body while pointing the device in the chosen direction. It could be towards a pile of combustible material for igniting or in the direction required to signal an aircraft, vehicle or individual.
