Personal defense device

Abstract

A personal safety device is provided to be held in a user's hand and to apply a striking force at an impact tip. The device includes a body defining a longitudinal axis, an upper end, and a lower end. An upper saddle may be provided to position the user's thumb over the upper end of the body. An index finger saddle may extend around the body adjacent the upper saddle to receive the index finger of the user's hand. A palm swell may curve outwardly from the body to fit into the user's palm. The body may be provided with smoothly curved contours between the saddles and the swell, so that the device is comfortably gripped and the striking force is spread throughout the user's hand. An alarm, strobe, camera, light, wireless transmitter, GPS device, fluid collection port, dye marker, straps, sheaths, and other defense and security features may be provided with the device.

Description

FIELD OF THE INVENTION[0001]A personal safety device may be used for defending against an attack on the user's person by providing an impact tip for striking the attacker. The device may be designed to fit in the user's hand to strengthen the user's fist to reduce the likelihood of injury, to provide an impact point or points for applying a force to the attacker's body, and to conform to the internal contours of the user's palm, thumb, and fingers to distribute the force from the impact point over the structure of the hand.BACKGROUND[0002]The human hand has a natural shape, common to all of us, in what is termed the position of function. In this position, the hand is believed to be most ready to provide a maximum gripping strength on an object. The position of function includes that the thumb is roughly in line with the radius bone of the forearm, the thumb joints are slightly flexed, and the fingers are more extensively flexed, i.e. they are bending inwardly toward the palm at the ...

Benefits of technology

[0006]The personal safety device described in the present application provides an elongate body sized and shaped to conform to the internal contour of a user's hand. The elongate body includes an upper end held under the thumb and a lower end held adjacent the little finger with the hand closed in a fist. The lower end typically extends out of the fis

Problems solved by technology

These attempts have had several drawbacks, including that they do not take into account the position of function of the hand.

Thus, the interface between the hand and the tool does not provide for a grip that distributes forces on the tool throughout the hand.

The lateral force in particular, depending on its direction relative to the thumb and fingers, may make the tool very difficult to hold onto.
